1 thing Sabine failed to mention about the Fukuashima accident is that the backup generators that run the cooling pumps were on the basement floor of the plants. So when the tsunami struck it flooded the basement rendering the generators inoperative. In an area with frequent severe earthquakes you would have thought the designers would have foreseen that.

The plant was designed and built according to american engineers, which had placed no thoughts to the idea that the generator room could be flooded, because they thought the tsunami wall would remove any form of danger to the plant what they forgot however is that their little tsunami wall was not really designed for the kind of tsunami that eventually did end up hitting Fukushima, even in Soviet Union the nuclear plants had several generator backups in case of WW3, there were several in bunkers, some on taller floors capable of all running the pumps in emergency, but in ol' Japan there no such thing as WW3 so its all peachy! Whats ironic is Chernobyl was designed to survive Earthquake up to 7 on the richer scale as required by all Soviet buildings in case of nuclear attack.

Great video as usual! I am a retired engineer from a large US utility company. About 20 years ago, I pushed, as best I could, the modular nuclear plant idea. My thought at the time was suggesting using pre-approved (Nuclear Regulatory Commission (NRC)), shop-fabricated and inspected (as physically possible, given size to ship), 200-300 MW (thermal) size nuclear modules. These would be based on, or exactly the same as, the proven (since the 1950s) Pressurized Water Reactors (PWR) that the US Navy uses in over 150 nuclear powered vessels. The thought was to reduce siting, permitting, warship reactors are "hardened" for war, and can withstand many G's (earthquakes), and construction times, via maximized shop-fabrication of nuclear and other components. As far as I can tell, from public information, these reactors have a perfect safety and reliability record. For electrical generation, the reactor steam (thermal) output could be headered together to drive a single large turbine generator or several smaller turbine generators. I could go on, but enough said for now. Keep up the great work...!!

[@T33K3SS3LCH3N]

The problems with modular nuclear reactors are that nobody has a real concept how to produce them at a reasonable cost. The projects so far have all exploded in costs. Test projects have failed. We won't see any serious designs until the 2030s now. There are also all sorts of other problems with using these at a singnificant scale. They generally either produce an obscene amount of waste or rely on completely unproven technologies. Small modular reactors sure look like vaporware at this point. They continue to get more expensive due to issues like rising steel prices and higher personell requirements. They then to make up for their problems by proposing increasingly exotic fuel cycles, making them less and less feasible. Whereas renewables and battery storage continue to become cheaper at a massive rate. And as the share of renewables continues to increase, nuclear plants become even less attractive since they are even less efficient if they get pushed into the role of load-following plants. Nuclear is already looking bad and only falls further behind.

Well, the world has moved on…now solar and wind are much cheaper. And that is not even mentioning hydro.

[@johninky5160]

@@JuanCEOs725 Wind and Solar are NOT suited to BASE LOAD (24/7) operation. And, many hydro sites are also NOT suited to base load operation due to environmental issues like fish habitat and other water uses. Nuclear plants run best at base load (24/7). Wind and solar are neither dispatchable, nor is their capacity committable. That is, their capacity and energy cannot be committed the day or week before to serve load and/or schedule other generation sources to load follow. In addition, their energy output cannot dispatched (controlled at will or automatically) during the daily load cycle. To make up for these wind and solar shortcomings, a system operator must either, commit (schedule) other generating units to have on-line spinning reserve capacity (much more than would be necessary without wind and solar on the system) and dispatch it to follow load, or have some type of energy storage device(s) (battery, compressed air, pumped hydro) on the system to allow load following during passing clouds, wind shifts, darkness, etc. Without some type of storage, generation capacity (power output, Megawatts) must match electrical load (power demand, Megawatts) in REAL TIME, second by second. Today's wind and solar, operating on a large scale system, is not as cheap as it may seem due to these (and other) accommodations required to integrate them into a reliable large scale electrical system.

Thanks for the video.

[@laura-ann.0726]

I was employed in the nuclear power industry from 1974 through 1988, and worked on design for Watts Bar unit 1, Sequoyah unit 1, McGuire Unit 2, and Catawba Unit 2, and lastly was employed for 4 years at Rancho Seco, which was operational by the time I arrived there. These were all pressurized LWR's, but I've come to wonder if the Canadian CANDU is a superior design. It has 1 overwhelming advantage over all of the American reactor designs: it doesn't have to be shut down every couple of years for up to 4 months at a time for refueling. The fuel channels in a CANDU reactor can be accessed with the reactor running at full power. The reactor is built on it's side rather than vertically, and at each end of the reactor, there's a big machine that seals itself to the fuel channels, and a new fuel bundle is pushed in at one end, while a spent fuel bundle, which has spent about 18 months traveling from one end of the reactor to the other, is extracted. CANDU reactors do occasionally have to be shut down for repairs and upgrades, but over many years, average "availability" of the reactor is around 90%, compared to 60% for a PWR. The CANDU has a high initial cost to produce the deuterium oxide (heavy water) needed for the moderator, but another advantage that offsets this cost is that the CANDU's fuel is natural uranium, so the U-235 enrichmnent costs of a typical American LWR are eliminated. The walls of the Calandria of a CANDU reactor don't have to be as thick as those of typical American PWR, so it's less expensive, and easier to transport from the fabrication plant to the reactor site. It may be possible to design the reactor and fuel geometry of a CANDU to burn Thorium-232 (a fertile isotope that can be bred into fissile U-233), or MOX, which is recycled LWR spent fuel that contains some Plutonium-239 in addition to U-235 and U-238. Any power plant is only paying off it's construction and operating costs when it's actually running, and there are very few other reactor designs that can match the availability factor of a CANDU. I wonder, if you did a detailed comparative analysis of all 4th generation reactor designs on the drawing board, if the newest proposals for the Advanced CANDU would come out a clear winner because of that high availability factor?

When Chernobyl happened, my young wife was pregnant and we were very worried about the health of our unborn son. But if you look at the death zone there today, it's a nature paradise. And technology goes on and gets saver. The tremendous danger, humanity has to face is the global warming caused by CO2 emissions, that have to stop immediately, and renewables alone cannot do that. So we should be open in all directions. Sabine is a bit on one side here, I don't see a sense in reckoning deaths from one to another topic. But anyhow she did a great job in provocing and starting a fruitfull debate. Coal mining causes low radioactvity if course, but over a gigantic region, while nuclear waste is ridiculous small, Sabine is right at that point. But it's not the major issue as you can see here in western NRW. Its the incredible land use, the destroying of whole landscapes and forests, the massive expulsion of the population - and we're not in China, toxic dust and an incredible amount of CO2 emission. Now Germany buys nuclear power from France and Belgium and imports fracking LNG, that's even worse than the own brown coal.

The catch is that you can sell solar panels and wind turbines without addressing these issues and just kick the can. Can you imagine if a nuclear plant stalled intermittently throughout the day?

LCOE is also just using Vogtle's build costs for its basis which paints a really misleading picture on costs as you're using a huge outlier, not the global average. This is due to the fact Lazard is more US centric as they've admitted to. Also, their Solar/Wind estimates do not include firming requirements, and the moment they did include it, it was only 4 hours MAX which is insufficient if you want a stable grid. Yet even with 4 hours of firming requirements, the costs actually balloon quite a bit nearing even their Nuclear costs. This is because nameplate capacity =/= generation capacity when factoring capacity factors which is around 25% for solar, and 40% for wind vs 92% for Nuclear. You'd need to overbuild more than 1GW nameplate capacity for Solar/Wind to even get near 1GW nameplate capacity for a Nuclear plant.

Doesn’t France do this? It has 56 nuclear reactor in operation and might build as many as 14 more by 2050.

(And other countries, such as South Korea and Japan, might be models for deploying uniform designs as well.)

[@Prometheus4096]

Yes, this is how nuclear power could compete with fossil the past 4 decades. You pick one simple design. You mass produce at least 10 to 30 plants that are very large, at least 0.5 to 1 GW. And you fund it all with tax payer money. That was the only way you could actually do nuclear in the past. But today we live in the age of cheap energy through solar and wind. Solar is beating dirty coal on price. No one is going to build a dozen of nuclear reactors. It is insanity. The market wants to pay for solar and wind and you want the US and Canada, or the entire EU to put 100 to 200 billion tax payer money into a new nuclear project? It just can't happen.

[@luciobaggio8695]

Keeping a fixed blueprint definitely helps cost saving, however size matters, too. In the big reactor businness, the building site will need a lot of unique features and infrastructures built from scratch that will preclude any benefit from economy of scale, ask the French with their PWR. Massive nuclear cores need to be welded on the spot, for instance. People like the Thorcon guys inverted the design phase by starting from questions as "how big today's existing shipyard facilities can off-site mass produce a steel core", then by sizing down the reactor to fit into those existing infrastructure capacities. Only then one can actually send the blueprints to those shipyards and ask "please, 1000 more of this". This should keep the time and cost (per kWh) lower than coal plants.

Very interesting video, as usual. One thing to note is that the planning stage was not part of this discussion, but it puts a hindrance on things. Lots of people don't even to have a Wind Mill or heck, some even don't want Solar Cells near their place. Regulations and laws allow the "Not In My Backyard" (NIMBY) problem to bring lots of projects to stop (at least for some time), even less impactful than a nuclear power plant. Planning more in the more densely populated countries will prove a challenge. Of course, how much political will can mean and could change: In Germany, entire villages have been demolished to get more coal. That's more than just a "Not In my Backyard" problem, that's: "We don't just want your backyard, we take your entire home and everything around it to do continue to do somethig harmful for the environment, and that's it". And Japan is also pretty densely populated, and they managed it to. I am still just not sure it's worth the effort and risks, if solar power and wind are as efficient as they are.

[@joshuasenior4370]

The issue with solar and wind is mainly the fact that they can’t provide a base load power i.e. they can’t provide the constant minimum reliable power we need for every day. If it’s not sunny or not windy, then you get no power. This needs to be filled by something like nuclear which can provide power all the time. And if not by nuclear, then it will continue to be fossil fuels.

[@evil17]

I like green energy to, but wind & solar do come at great cost & are susceptible to storm damage, take up a lot of area sometimes native protected species, koala’s, birds, etc, and don’t supply a base load of power 24/7.

Love the discussion about construction time. One word of warning though, we might exclude the time to build some of the earliest plants because their construction was much simpler. With improved safety standards, some of those plants would not be allowed today. As the industry matured and post TMI, requirements have changed and thus plant designs. A small criticism, but I think we should be careful of this. Another factor that has changed besides overall plant design is the (in the US) shift from separate construction/ operating licenses to a combined one. Some plants in the early 70's were built under one permit, but then sat unusable until a separate operating permit (with long reviews, public hearings all over again, and other beauruacratic delays) was granted. I guess the point is, that historic construction times must be looked at warily.

[@jeffbenton6183]

You're probably right. While we're on the subject of reactor construction time, I wanted to bring up that the US Navy builds reactors fairly quickly without a single accident in it's entire history operating them. The time it takes is mostly red tape.

[@gymhayes4613]

Id argue that the time differences probably dont matter. Sure they had less red tape but the tech was new and being desinged while being built slowing down construction. Where now we have more red tape but safer facilities that are much easier to get parts for and build than the first ones being designed. Overall these factors probably cancel eachother out. China and japan being able to do them faster tells me its more about labour slowing down a build. As their countries view labour differently than the west.

Fairly well said. One thing I should point out is that the "freeze plug" passive safety for Molten Salt Reactors has gone out of fashion now. There's a better way whcih I've heard referred to as "bucket" safety. Instead of a plug that has to melt in the event that the salt gets too hot or the power to the plug cooling goes out, the core is ALWAYS draining into the safe storage tank at all times and there's a pump which brings it back from the storage tank and into the active reactor. This version still ensures that in the event of a power loss (or if high temperature is detected) the pump stops and the core safely drains away and cools down but because it operates continuously you can be absolutely certain that it works and it works at the speed it's supposed to work at.

[@clarkkent9080]

I actually worked in the nuclear industry for 40+ years at five different facilities including one in California ....as if that really matters. Here is what matters: New nuclear is the most expensive way to generate power. Old nuclear power plants can be operated beyond their design life but it is NOT economically feasible and the reason why so many fully paid for plants are being shut down by the investor owned utilities. Diablo Canyon Units 1 and 2 can only continue to operate IF the state pitched in a billion or so. Biden that has a $30 billion slush fund to bribe utilities to keep old plants running has offered a billion. These plants may be required to keep California's grid powered but that is only because it is so hard to build new power plants in that state. These plants will be shutdown in the next 10 years no matter what. The state needs to decide if they are willing to let natural gas plants be built, buy expensive power from other states, or limit their grid capacity. New nuclear is not the answer as proven by the VC Summer nightmare and the massive cost over runs of Vogtle. Diablo Canyon Units 1 and 2 are already beyond their design life and it is only a matter of time before they shutdown.

​@@MarcoNierop I'll start from the end of your comment: 1- I do agree that is a terrible statistics, because that is NOT how you make statistics. You need to look at the death toll per TWh of energy produced. And nuclear is even safer the wind and solar. 2- That video you mentioned is a total mess of cherry-picked misleading if not at worst completerly false information. (like France's nuclear fleet water consumption and weapon proliferation) 3- Comparing the costs (LCOE) of energy sources is a very misleading and blind comparisons. If you read the last assessment of LAZARD on the LCOE, you notice that if you inlcude the firming intermittency you get a higher cost value than the energy produced by the most expensive nuclear plant in the world (Vogtle, Georgia) Anyway, in general, that is true that the cost of VREN is lower that nuclear but a WHOLE system with only VREN, compared with a system which include Nuclear and VREN, is actually higher because you are NOT taking into account the system cost. System cost are NOT the VREN's costs but rather they are the cost to stabilize the solar and wind intermittency and to bring renewable energy where you actually need it. Because i cannot place for example wind turbines whenever i want, but i need to place them where wind is avalaible. For example, off-shore wind turbines in UK sells their electricity for around 30£ per MWh which is really cheap. But in order to connect those wind turbines the UK government also allocated around 54 billions pounds to connects wind turbines to the grid. Those 54 billions are NOT counted in the LCOE costs of VREN. They are actually "hidden" system cost. The aforementioned is just the tip of the iceberg, there are also, backup system (batteries), backstop system, grid guarding system, energy flow management system, curtailment, capacity market, dispatch priority, duck shape curve and so on... The energy cost is just a single variable. Electricity cost are of interest for the investors. Lower electricity cost doesn't mean lower electricity bill. the "costs" are not the "prices". The price of electricity is determined by the system marginal price, therefore by the demand and offer mechanisms in the energy market where production costs is just meaningless because all the suppliers are then paid by the same amount of money. Lower cost means a higher net income for the supplier and the investors. The consumers should care about the merit curve. Nuclear have the advantage of decreasing the merit curve which means it actually reduces the energy price, because its not important to substitute the lower part of the merit curve, but rather you need to displace the higher part of the curve which are the fossils fuels and thats what makes the final prices. If you look at the report by the european commissions on the actual energy prices, you can see that France electricity is one of the cheapest of the whole Europe.

TLDR: 11-12 years for the building time is more realistic, because construction time is measured from first concrete pouring and ignores the steps before construction can start (planning etc.). But 75% of projects experience delays and take longer. Just looking at build times is not a good approach. Well, the construction time is a flawed statistic in itself. It ignores the time that is needed before construction is started, finding a location, planning, contracts, etc. takes multiple years as well. Also the construction time in the statistic is starting with first concrete pouring, it therefore ignores the time of construction site preparation, which is significant. According to researchgate the time for site preparation takes between 18-24 months. The source assumes 52 months for construction itself. But the excavation needs to be added to that which usually happens together with the first concrete pouring and comes down to ~12 months. So 52+12 months for construction and + 18-24 for site preparation. All of this is still not including the stuff before the major contract which is usually the kickoff for the site preparation phase. This time is often ~2.5 years. So even if we decide to build more nuclear reactors, we won't have them in 2-5 years, 10 years is more realistic if other times are included, if there are no protests and court dealings and political decisions delay the time before and during construction. This happens very often. This is based on the study "Importance of Advanced Planning of Manufacturing for Nuclear Industry", which gives a time of 11-12 years for the process. It also mentions that about 75% of the projects face delays, so take longer. 11-12 years is the baseline.

Fine video, thanks. But let me comment to some details (I have nearly 32 years professional experience in NPP, mainly Chemistry, Reactor Physics, Health Physics, nuclear waste etc.). You're right, Fukushima is an example that even in worst case conditions, nuclear power with light water reactors does not kill people. But it could have been avoided. The main reason, "built too fast", is rather the occurrence of tsunamis, happening every some decades, were not evaluated during commissioning. The government must be blamed for that. Second, management failure during the accident was horrible. Societal restrictions worsened the scenario. There should absolutely be no restrictions about who can of may talk to whom. During the accident, I followed the incoming news and was desperate. In my head, all the training about accidents was rolled up and I saw helpless the catastrophe coming. About the explosion of hydrogen: They had no recombinator catalysts (Palladium). In a rich country like Japan, no one can tell me that they hat no money to buy these essential things in a case of LOCA and meltdown. About construction costs and productivity: I agree, that management failures are wide spread. But one main problem to delay constructions is on the regulatory level. I one applies to build the same reactor on different sites, the authorities differ and have their learning process, individual questions, huge delay. In Germany, one solution found at a place was not accepted in another state. The other issue is the number of suppliers of nuclear grade materials. Today, you are lucky to find one. In the 1970s, there were several, number growing. Problems occur when manufacturing faults are detected very late. That rises costs enormously. During the last decade costs to finance long therm loans would have been low. In Germany, we calculated the costs for fuel and operation about 10 % of the total costs. In case of Natural gas, the fuel costs dominate heavily. The very high energy density is the main advantage of nuclear, as you said. But, as known for decades, only relying on U-235 is not the solution. But, all opportunities with U-238 and Th-232 combine technical issues with weapons grade material in hands of unscrupulous dictators. To solve the energy problems of the world, nuclear energy can't be restricted to stable democracies with skilled and educated personal. And, are those democracies really stable? To reduce the amount of nuclear waste to be stored underground, reprocessing is necessary. In the wrong hands, even these plants are dangerous. Sure, I'm a supporter of reprocessing instead of direct disposal.

The idea that a higher cost by a factor of 2 or 3 is not huge, is a good example of how the perspective of a Physicist may still be very skewed when talking about economics.

@@marcosolo6491 I wasn’t arguing in favour of fossil fuel! I was making a purely economical remark. There is no indication in her video (and in general) that economies of scale apply to the production of nuclear plants. You may be right, but sisnce I’ve seen no evidence of it I cannot take your position at face value. A 2-3x greater cost is really large and I don’t believe it’s gets “drowned out” as we have more plants. The profit margins of most companies are actually really small and expecting them to take such a risky bet is hard. I think the best way to argue in favor of is what she suggested: to research contexts where the construction time was shorter and more efficient and understand clearly the causal factors there. as to the final point: the point of the entire video is precisely that to this day, economics may be the biggest hurdle to nuclear and not peoples opinion about it, without discounting that they both matter

[@crt137]

​​@@86damn86she does make a point on economies of scale. She said lack of skilled labor and bad management from inexperience delays constructions which directly contribute to costs. Building more NPPs directly contributes to industry experience, improving labor productivity and reducing total construction times. Especially in an industry like nuclear where cooperation between plants is substantial. Also, and this a controversial opinion so feel free to ignore me, but costs for coal are only cheaper because they are externalized to the rest of the planet. It's a quirk of an unregulated free market and governments are "supposed" to make sure those costs are reflected in the construction of fossil fuel plants. If we, as a species, knows that fossil fuels are bad, why would we let a man-made system like the economy stop us for implementing the right solutions?

That is a strong hypothetical. If that is what she is arguing for, I would expect her (or anybody) to do so with the same scientific rigor that she brings to other matters. My original point was not that economics of scale are not possible (see my comment to the comment) but that her arguement is overly simplicistic when it comes to economics. She has a history of overstepping her expertise into other fields, especially social sciences, and her statement seemed to me another example of that.

Unless it's a corporation or a tunnel girl. And corporations made sure that their lobbyists go for the most ridiculous regulations that make it harder for small scale homes so that the only ones who'll build and own are bigger landlords that have in-house architects that slave away and some very well paid people that are there to find/create loopholes so they can save a couple of underpaid architects. Why do you think home inspections are not mandatory? On the other hand you'll have government employees that are trying to stay up to date with the latest "tricks" while at the same time not being as bright as those 500+k/yr people who are creating them. At the same time they'll certainly won't do overtime for Joe from rural Kansas and are anyways already understaffed(Republicans are very good at causing that - not that they're the only ones). This leaves you, Joe, with long wait times and high fees for a 700sqft bungalow. The US is afterall the biggest socialist country in the world: corporation losses are spread among everyone and profits are kept. As for nuclear power plants: we're no longer talking about a bungalow anymore I hope that's clear. There have been plenty accidents already in nuclear power plants and each causes new regulation to come in place. The regulations are so complex that you really have to get multiple (highly specialized=expensive) people just to implement and oversee them. Most of these plans are already accredited(in fact, in most countries you're not even allowed to just come up with a new design - governments don't even want to touch that stuff). As far as I know, all accidents this century (only a handful I think) have been due to not abiding by regulations. Almost as if they made sense.

22:00 - another issue with the coverage of the Fukushima disaster is that it has nothing to do with the plant and everything to do with the flood wall, which the company dithered for years about raising to the level they should've been at.

[@EDE_358]

Right. All other NPPs on the same coastal line who were hit by the Tsunami were covered by flood walls of about 9m height. The Fukishima plant had a 6m wall, not high enough. The scandal is that 2 years earlier engineers demanded an increase of that wall. With the help of politicians the operator managed to circumvent that. In short: Similar to Chernobyl or to the Explosion of the Challenger Space Shuttle poor human made decisions were the cause. Technology should be child proof.

[@piotrd.4850]

It had everything to do with the incorrectly designed and inspected and operated plant which shouldn't be there in such shape in a first place. You see - there was another similar plant nearby, with backup generators installed PROPERLY. No drama whatsoever. Fukusihima with 3 reactors on meltdown was collosal FAQUP, saved only by containment vessels. Also - it has problem all huge PWR/BWR share - heat dissipation.

[@ryukisai99]

Thank you Sabine + crew for this nice video. Yes in the 70s 80s many countries were building Pressurised Water Reactors quite efficiently in large numbers. In these times they had nice teams of specialised workers that had training, experience, were iteratively getting more efficient, plus these programs were backed by governments. Side note: PWRs are normally much safer than Chernobyl's RBMK or Fukushima's Boiling Water Reactor. The current PWRs being built are impeded by several context issues: First of all they must indeed meet much tougher (nonetheless desirable) standards than the existing plants. Second the workforce has to be mostly trained from the ground up. Thirdly the work organisation of modern companies tend to rely too much on management (implying less productivity since there are now almost as many white collars as blue collars). I firmly believe in nuclear energy as a viable way to help reduce co2 emissions. Yours truly, a former blue collar of the nuclear power field (9 years+ experience in both reactor maintenance and construction).

[@iurlc]

Whats so nice at this video? The statement at 1:00 that there is only a little waste - ok 15.000t in Germany is real a little waste. But we have no idea where to place this little 15.000t. When atomic wast store ASSE was opened, it was promised, that the waste is save for 1 million years. A few years later the waste come out and now we have an further big cost issue to solve the ASSE problem. And yes it would she not bother at all to live near nuclear waste, because it would not happen to her. And we have now good other possibilities to get rid of the nuclear waste. We put it into bullets for the army and should on countries which we don't like. I have seen a man who suffer from nuclear waste in real. To get an first impression whats going on look the video "deadly dust" from Frieder Wagner. I would really know where she has the numbers of did by nuclear events? And then she compare it with people die on climate change - where we have no real sign for it. It was claimed by climate experts in 2007, that in 2013 the North pol is ice free. Now we are 10 years above and its still ice there. 2018 it was announced coldest temperature in antarctic since measurement are done. And what all about the statistics of building time - and Japan with 3 years. Do we not know, that they where to fast - they made mistakes in evaluating earth quacks? And US - did they in the past not work to fast and not evaluting the human factor - think about 3 mile island? And yes the insurance fee is low - because in case of an nuclear event, the liability for the operator is limited. Exceeding cost have to take over the state - so we all. And also very interesting - manufacturer liability is excluded. The new housing for Tschernobyl was paid from a lot of countries. And this housing will last only a few decades. Then additional big cost will rise up - a never ending story. And it is more expensive than solar power. So why we should spend money into expensive system, where a lot of cost for nuclear waste and nuclear events still not included? And small nuclear reactors are fine? Due to the high number of reactors needed the statistical chance for fault rises up! The only explanation for this video is - she get paid for it.

[@connieeify]

​@@iurlcLet me clear some misconceptions you have. The waste Storage in Asse was never intended as a final storage facility, that's why there was only mild and medium radioactive waste stored there (so mostly contaminated labtrash or construction waste). In fact is was seen as a test site to research the long-term storage of nuclear waste. A different story is Gorleben, which was a final storage, but that location was mainly chosen for political reasons (it's very close to the GDR border). Uranium bullets are not nuclear waste and not radioactive. You would damage yourself more than the enemy, if they were. In fact Uranium is used because it is dense and hard, ergo good to penetrate armor. The real way to recycle radioactive waste, and now I mean burned fuel rods, is recycling/refurbishment. Plus the fact, that newer reactors probably use the fuel more efficient so that you don't have to through away your fuel rods after only burning 5% of the fuel.

[@connieeify]

​@@iurlcFor the climate change comparison, I think Sabine is talking about future deaths here. Further, it's hard to pin done the death toll here anyways, but if we say e.g. that the Ahrtal catastrophy, was only caused partially or made worse by climate change, we have a higher death toll easily than Fukushima has. Though I have to criticise Sabine here for here Whataboutism.

That is a valid point. For us who grew up in the Cold War era, even the word 'nuclear' causes some anxiety. So it's is hard for most people who went through that to separate the difference between nuclear war and nuclear energy. But we are slowly getting there. Really, we are just on the cusp of this new technology, even though it's been around for decades. It's only now that it's need and understanding is reaching the masses. But it will be a whole new industry. Just like when we started flying airplanes, then military jets, then commercial airliners...we went through some pretty steep learning curves. Same with the creation of railways across the world, vehicles built on a massive scale and the building of highways and traffic systems, the building of the first traditional power lines and telephone lines, building oil rigs in the oceans, and even the invention of the internet. It is akin to the beginning of the Industrial Revolution all those years ago. But now the Technical Revolution I guess. But the same challenges. In the end we will have a whole new industry, a whole new set of educational programs to supply the skills needed both in labor and administration, a whole new infrastructure of getting that energy to market. So, not only will be have a chance at saving the planet, we will also create many, many jobs. Even in the US, cities like Detroit and Chicago, who used to rely heavily on industrial companies for building cars, steel plants, logging, shipping, and more, who are now without those industries and have plunged into decline for many years now; well, they have the potential to become places that produce nuclear energy, thereby reviving the cities. It's just an example. But the point is that nuclear energy is where we are going, have to go, and will provide benefits that society in general cannot even imagine right now. There will room for blue collar workers, white collar workers, entrepreneurs, and everything in between. It's exciting I think. And I grew up in the cold war era. Literally in grade 1, along with fire drills as usual, we did 'nuclear bomb' drills. It was simple. Hide under your desk, keep your eyes closed and cover your face with your clothes, breathe less, and pray. Pretty stupid looking back. But what else could we do? lol

Decomissioning, risks and radioactive waste are never included in the total costs. Those costs are externalized. There is also no insurance company that takes the risk for a nuclear power plant.

With PV costs below 1ct per kWh, the nuclear power BS will find its natural termination.

[@ryoukokonpaku1575]

Decommission data is plenty and is often factored into a plant's costs. This is because plants last super long (most running up to 80+ years with recent regulatory updates) that they can get enough revenue to pay for their own decommissioning without subsidies. The biggest issue is often the initial construction costs and interests, due to that a running plant in the west would take a quite a bit of years to actually pay that debt even before they actually start turning a profit.

Main few problems is: 1 we dont have a common way to build them - so checking for errors and improving them with the red tap becomes a nightmare. 2) Larger and larger something gets - the larger the complexity gets as well and that means any changes can reset the design/building back years. Recommend we just stop building bigger plants - and start looking at making them smaller and more module in design using a few companies to make them in house and then ship out to locations instead. This would fix a number of those issues and make any red tap issues really a non-issue as you can just keep improving the design for everything under the sun. The design though would have to be shared across countries - or at least - work togather to make it happen. NATO could allow for this. Granted, Solar isnt much behind either... in terms of new tech that could help 1) make it cheaper, and 2) improve the collection rate from 20% up to 40%. Batteries are also going to see some improvement here shortly as well by moving away from Li to Na follow up by getting away from active carbon to Si and S for double the power dens per cell 180 -> 540 for home and grid scale storage.

Also, it is somehow inappropriate to only consider construction time when e.g. planning does takes months or years. Time is running up and every year counts. 2. You compare the cost of nuclear power plants with other energy sources. However, you state that nuclear energy is much cheaper in e.g. China etc. But isn’t it also the case that solar, wind,… are much cheaper there? This has to also be considered.

Hello Sabine, when discussing LCOE for different generation methods it is also important to consider the limitations of LCOE calculations. As long as there are limitations to energy storage, not every kWh is equally valuable as electricity generation has to be matched to the current demand. This is escpecially true for intermittent energy sources such as wind and solar and makes nuclear even more competitive because it is assured low-carbon power.

Storage costs 45$/MWh. Just buy enough: battery, gravity or hydrogen. Still waaaaaaaaaaaay less than 222$ for nuclear.

Construction time and cost arent even the main drawbacks. Uranium has to be imported which makes you very dependant on the exporter Nuclear power is non renewable and currently makes a very small % of our energy sector. If we ramped up production uranium would run out in a few years.

[@traumflug]

Her consclusion is quite odd, though. "Nuclear costs just twice as much as other plants, so we should build nuclear." Everybody else would build these other plants.

[@abslon4772]

​@traumflug I think the conclusion makes sense in context. Nuclear is 2 or 3 times more expensive than solar. But that difference in cost is in part due to no political will existing for nuclear. And lack of experienced people to build modern plants. If we started building plants, we would get more efficient at building them, and make the costs approach solar and wind. Now nuclear will likely still be somewhat more expensive than solar or wind, but that is fine because they are not direct competitors. The biggest problem with solar and wind is that they can not run all day. While Nuclear is best for providing a base load of energy throught the day. So in that context, it's fine if nuclear is a little more expensive as it is more reliable.

[@traumflug]

@@abslon4772 Except that this "context" is pure fantasy. Hundreds of nuclear plants exist already, nuclear had plenty if "political will" for several decades. It didn't work out.

[@riky-gl8nl]

Just want to add a thing or two that were slightly out of the scope of the video. When talking about cost usually we talk about LCOE, but LCOE is not perfect, in the case of renewables it fails to consider that becomes progressively difficult to add new renew sources past a certain trashhold that is different from state to state. Also it fails to consider cost of system (renew such as solar panels and wind turbines are more "diffused" so you need more connection to move the electricity from point A (where there are ideal condition to install these sources to point B the consumer), also, they do not take into consideration batteries to store the energy. Essentially while using LCOE it appears that renew have a big advantage over other sources when other variable are taken into account then there isn't anymore as clear of an advantage. If you want any source you can search for different metric, the IEA has suggested a metric called "VALCOE: Value adjusted levelised cost of energy"

[@frankb__431]

Adding decentralized infrastructure like solar power does not strain the grid significantly. The grid connections for solar power are already there and since the electricity is sourced AND consumed locally the necessity for huge transmission lines that carry GWs of Power is reduced. You might have a minor point with wind power but in reality your argument actually stands against huge power plants which additionally add lots of several points of failure to the grid. There is some merit in considering the cost of energy storage solutions for LCOE but these as well synergize with other necessities in shifting the way we use energy. the use of fossil energy for things other than electricy gets overlooked frequently. Natural gas is used for heating, liquid fuels are needed for transportation purposes. Coke is needed for steel production. The list goes on. Liquid fuels will still be needed in the future as electrifying is not viable e.g. for planes. Steel production will need to switch to a hydrogen-based process. Storage infrastructure for renewables is contrary to popular belief not only batteries but consists mostly in the need for a hydrogen-infrastructure. The hydrogen-infrastructure can provide replacements for bot liquid fuels as well as natural gas. That also leaves the possibility to leave gas-powered infrastructure (from single home heating appliances to natural gas power plants) in place and utilizing it further until it can be replaced organically due to not being needed anymore. Those synergies are the reason why just adding the cost of storage infrastructure to the LCOE of the solar grid is not viable. An honest approach would be to look at the LCOE of battery storage separately, knowing that it will be quite high compared to the LCOE of wind or solar power. One might argue that we can build nuclear powered hydrogen infrastructure as well, but that would be ON TOP of the already high LCOE of nuclear power AND you would need even more power plants to cover the energy needs. Even narrowing the topic down to electricity Sabine seems to ignore the practical side of things. Building one NPP might take 3-5 years but as another commenter discovered as well, you can only build so many at once. Replacing only fossil electricity would take 20-30 years but then there's a giant supply gap for replacing direct consumption of fossil fuels. I am quite bummed about Sabines narrow and incomplete approach to the topic in this video as she does not really consider anything besides electricity. For 2022 in germany electricity represented 21% of the total direct energy consumption with natural gas taking the top spot at 28%, mineral oil at 18%, coal at 15%. At this point it is fair to say that Sabine leaves out 80% of the problem to make her numbers and conclusions look good which is at most a sorry excuse for a scientific approach.

[@riky-gl8nl]

@@frankb__431 I partly agree with you but some things I want to add: 1. Hydrogen is a power vector whose efficiency power to power is around 30%. Hydrogen is quite voluminous so it's difficult to carry in its gaseous form, so you would need to invest energy to convert it to a liquid and then back into gaseous when you need to burn it. 2. The cost of a hydrogen infrastructure is huge, while I too think it will be used to some degree I doubt that it would be able to completely substitute fuel and natural gas. 3. There is the cost of production, currently hydrogen is nearly entirely "gray" hydrogen the one produced by natural gas. The "green" hydrogen is extremely low % and has the problem of cost, renewables produce intermittently this means that you can have periods when the electrolysis plants are not working and period when they are. What do you do? Do you build enough so that no energy is wasted? Ok but then you have some plants that are non-operational 70%-60% of the year. 4. "Pink" hydrogen (the one produced with nuclear) seems good (as of cost/production) because it's a bit more reliable and constant compared to "green" hydrogen" but data is still limited.

[@frankb__431]

@@riky-gl8nl thank you, great response! 1. That is true. Hydrogen is expensive, but needed for lots of processes in the chemical industry with steel being the most prominent example. Nonetheless we won't get anywhere without a hydrogen infrastructure albeit limited to the applications where it is not feasible to directly use electricity in any way. Planes and ships come to mind. Those will also be the fields where energy costs will rise. 2. Indeed it is. But I don't see any viable alternatives that would allow getting on a net zero path. Carbon sequestration on that scale is equally as expensive while not really providing a final solution AND not benefitting from the synergies I mentioned. 3. Yes, I think that we will need loads of capacity for hydrogen synthesis. Upside is that it can be used as a means to regulate grid stability. Currently the grids are regulated on the supply side. In the future grid regulation will take place mostly on the load side. What we have to consider is this: We don't need enough production capacity to cover peak outputs as we can utilize short-time battery storage as well. The problem is that a hydrogen infrastructure is needed nonetheless, although to a lesser extent (guesstimation: at most 30-40% less?) for a nuclear powered grid at the cost of losing the synergetic and therefore cost-cutting effects with seasonal storage. Meanwhile hydrogen production facilities are much easier built and scale much better to higher capacities than a NPP. 4. "Pink" hydrogen seems good but one of the strongest argument for expanding nuclear energy is that we would not need that much excess production capacity. From my understanding pink hydrogen would introduce the same excess capacity through the backdoor. Speaking as a german we are currently at ~70GW peak consumption. Pink hydrogen would double or triple that number leading us to a whopping 100-200 additional reactors needed. At this point all the public bawling about shutting down our last 3 reactors in 2022 is not even remotely adequate.

In Asia in the 2000s they have programs building several reactors of similar type after each other. If you do that in Europe and the US you will likely get similar costs for the plants. That is more important than SMR:s (which is likely a little bit too small to be cost effective).

In the 1970's nuclear construction halted rapidly as the US and France realised they had overbuilt and the costs were higher than expected. The chinese built about fifty in short order, but they also slowed down remarkably. Maybe they are not finding them as cheap or straightforward as advertised? Certainly they have doubled and redoubled renewables construction in the same time frame, so they want the energy. Increasing build rates in the US is unlikely to get the sudden economies you suggest. Even if Santa could just give the US a couple of dozen new reactors for free, they might not stay open. In the last twenty years, the most common reason for closure has been "operational losses" on paid-off plant, with plants closing an average decade before their license expires. SMRs are not just a "little" too small for economical operation. Gigawatt(electrical) plants are uneconomical. Globally, over 100 Nuclear reactors are likely to close by end of 2030. Build completion rates would need to increase by 2.5x just to maintain existing capacity. Nuclear engineering graduate numbers are stagnant or down compared to the 1990s, and all of those will be required for decommissioning work. There simply is no scope to increase graduate numbers without a three to five year delay, and no scope to even marginally increase the fleet without more than triple the present build completion rate.

[@torericson2089]

I agree with you. It will be a challenge just to keep the same power generation from nuclear power as today, but maybe that is the ambition we need to have at least. The key problem is how the future energy system should look like (let us say in year 2060) if you want to get rid of most of the fossile fuels until then. When you have maxed out the amount of wind and solar that is practical to deploy without costly and difficult massive storage then all alternatives will be costly and difficult to handle.

@@torericson2089 I do not think that even maintaining existing nuclear capacity is a worthwhile ambition. There are states with 70% non-hydro renewables, and no indication that there are limits to further deployment. Storage requirements can be minimised by planning further rollout to match the highest spot prices. Placing PV further west and orienting towards the western horizon extend solar generation later in the day, supplying more of the evening peak consumption directly with less storage. Choosing wind sites with consistent late afternoon and evening winds does similar. Even if we hit some point, say 95%, where supplying the last 5% is more expensive, the question is then "how expensive". At that point, not very. Not only are renewables costs still falling, but supply lines are stronger, with more stock awaiting installation or upgrade than ever. Putting this generation and storage in distributed locations that otherwise see little use need not be a loss, it can be an investment in resilience: Community emergency centers with facilities in case of floods or cyclones, and other public buildings. This last few percent may be under-utilised, hence expensive, but not "difficult to handle", as they will simply be "more of the same" of components that are commonly available. There may be some very remote regions at high latitude where nuclear will always be necessary, at unavoidably high cost. Maybe. However, in any location where renewables can function at all, even at low efficiency, they will easily undercut nuclear, which simply isn't getting cheaper at all.

It would be helpful to also take a closer look at those numbers. To even look at build times from the last millenia is not useful, as security standards have, for good reason, dramatically improved since then. (Fukushima hadn't happened if the plant would have been built according to todays standards.) China however is much faster in building nuclear plants. The USA was faster, but haven't built a nuclear powerplant for more than three decades.

Hi Sabine, as always an interesting video, however I'm left with few questions 1. Does cost analysis include a clean up cost after all major events world wide? What would be a mark up on energy if we distribute that cost over every MWh of nuclear energy produced world wide? I just did a rough calculation for Fukushima Daichi and for this power plant a clean up cost is min ~380$/MWh. For Chernobyl it is min ~600$MWh. There was an article in National Geographic that mentioned (if I remember correctly) that Belarus lost ~20% of land due to contamination. If that is true that what is an economic impact and cost of this. 2. Is it right to extrapolate that if accidents happened in the past, they will happen in the future, regardless of technological advances? Especially when we live in the world of increasing terrorism (not excluding USA and Russian governments). After all Fukushima design didn't predict what happened, so can we predict what we can't predict?

[@kanucks9]

To answer 2. First: No. We can expect future reactors to have fewer, and smaller accidents. To answer 1. note that there were two major incidents against 667 reactors ever built, so you must divide your values (av ~$500) by 667, for $0.74/MWh, as an upper limit to the total cleanup cost for incidents.

The world has produced roughly 92,000 TWh = 92e9 MWh of nuclear electricity since Chernobyl.

Let's say it goes up to 200 billion USD when all is said and done. Then the average cost is 200e9/92e9 = 2.2 USD/MWh. *"There was an article in National Geographic that mentioned (if I remember correctly) that Belarus lost ~20% of land due to contamination."* I really doubt that, but we should be mindful that the contamination is Cs-137 with half life of 30 years, and 30 years had first passed in 2016. If original land lost was 20%, it should've been 10% in 2016 and will be 5% in 2046, even ignoring sedimentation and such. *"Is it right to extrapolate that if accidents happened in the past, they will happen in the future, regardless of technological advances?"* No, of course not. Chernobyl was a Russian design without containment, negative void coefficient and graphite cooling, giving a prompt criticality accident and then burning graphite that helped mobilize the inventory of radionucleides. Fukushima was a triple meltdown with 1/10th of the Chernobyl release, i.e. 1/30-th per reactor. New reactor designs have probably 2 orders of magnitude lower accident frequency due to lessons learned and longer core cooling reqs, and they also have tougher containment, ventilation and more preventing hydrogen explosions, so any core melt should stay enclosed like in TMI. Also there's e.g. more accident tolerant fuel being tried out now. So if Fukushima era reactors gave 2.2 USD/MWh in accident cost, we can assume gen 3+ reactors having

Very informative and interesting video. I also liked the football joke. It reminds me of an article in the Guardian: "Football pitch-sized area of tropical rainforest lost every six seconds". Here in Oz an observant ABC reporter once pointed out that if we reforested one football field every six seconds then we could not only compensate for deforestation but also help reduce certain kinds of bad behaviour. By the way, it seems to me that the graph at time 6m42s in the video has 'median' and 'mean' swapped.

[@tobias131314]

Re median/mean: I initially thought this too, but actually the video graph is correct, since the mean always sits closer to the “long tail”, which in this case is the left side of the distribution. Though the video would have been much clearer if instead the example graph had the long tail to the right (long tail of high values instead of long tail of low values), showing how the mean becomes artificially high when a small number of high values are included, which is the point of the Sabine’s argument. Whereas the video graph shows the opposite example where extreme low values bring down the mean, which despite being valid, causes confusion since it’s incongruous with the discussion

Thank you, Sabine, for some rational words on this topic 👏

[@deadwalking100]

Dear Sabine, you are one of the great science educators of our time and I amongst many have greatly benefited from you and your teams wide ranging knowledge and scientific insights...along with the ability to convey complex scientific issues to a wide audience; and of course not forgetting sense of humor. Thank you! I do have a question about costs; decommissioning to long term disposal of waste. Are these costs added to the final total cost of nuclear power? 🤔 The expenses related to decommissioning are substantial, and often the estimates are prone to surpass the initial construction costs of the plant. 🧐 The time it takes for the radioactive waste to be considered "safe" for disposal can span thousands of years, posing long-term challenges for safe waste management. ☢ One notable example of decommissioning costs is the case of the San Onofre Nuclear Generating Station in California, USA. The plant was shut down in 2013 due to safety concerns related to faulty steam generators. The estimated cost of decommissioning the San Onofre plant was initially around $4.4 billion. The decommissioning process involves safely dismantling the plant, managing radioactive waste, and restoring the site to a condition suitable for other uses. The high costs were attributed to the complexity of the decommissioning tasks, including the removal and disposal of nuclear fuel, decontamination of equipment and structures, and the need for long-term monitoring of the site. This example illustrates the substantial financial commitments required for decommissioning nuclear power plants, which can be a significant consideration in the overall evaluation of nuclear energy as a power source. Don t get me wrong I am not against nuclear par se, indeed in the first instance will I am sure no doubt be needed to drive our off world endeavors.

[@hardcorelace7565]

I think that the parts of nuclear waste that take thousands of years to become safe are quite rare compared to the majority which becomes safe relatively quickly, as sabine said some of it can be recycled and reused quite quickly. Also when fusion becomes possible several nuclear fission byproducts are required for the reactions, so more waste will be used then. It is a good question that would do well with a very in depth and researched video though! 😂

[@MattCasters]

@hardcorelace7565 That wasn't the point of the video. She aimed to answer 2 questions on construction time and costs. She essentially confirmed that it takes too long and is at least twice as expensive per kWh. The rest were arguments why we should ignore all that because nuclear is going to save us because "science". I disagree on behalf of poor people.

[@hardcorelace7565]

@@MattCasters it's more expensive than the alternatives in other renewables and fossil fuels, but fossil fuels are terrible for the environment and are going to run out, and nuclear is much more space efficient and location unrestricted than other renewables. And if we build more nuclear plants then each one gets cheaper and faster to build, since a lot of the cost is due to time to build, and time to build goes down when experience in building nuclear plants increases. Japan can build nuclear plants nearly as fast as other power plants and not much more expensive but much less environmentally unfriendly than fossil fuels and a hell of a lot more space efficient than wind or solar farms, hydropower is still better but those can only be built in very specific areas. There are pros and cons. However we should try and keep as diverse an energy infrastructure as possible, as with wind and solar especially reliability can be a problem. And BTW, poor people aren't going to be paying for these, the money a government subsidises for nuclear plants has already been taken from you, them building one or not means nothing, your money is going to be spent on something so it may as well be spent on more energy infrastructure rather than a politicians pay rise. And private companies will also be paying for these so it's not like governments are paying the full price. $10 billion isn't a large on the scale of government spending, the US pays $800 billion on its military alone, if they reduced that by half and spent it on nuclear then they could pay for 40 of the unrealistically priced plants, they could pay for like 50-60 regular priced ones.

Thank you Sabine, it’s very useful to have context on the risks and cost of nuclear power. While SMR appears to offer cost reductions, France has approved the build of 6 EPR2 reactors. SMR deployment in France is not expected before 2030.

[@danilooliveira6580]

yes, that is the sad thing, SMRs are not better or more efficient, they just skip the bureaucracy and complexity of construction. I legitimately think SMRs have their place if they do manage to make it cheap, but ideally we would be building more large reactors.

[@NoName-cx3gk]

Regarding your point about SMRs and the recent decision by France to build EPR2 reactors, it's worth noting that SMR technology is still evolving, with promising developments like the Integral Molten Salt Reactor (IMSR) by Terrestrial Energy. This Canadian innovation is an example of how SMRs can go beyond just reducing bureaucracy and construction complexity. IMSRs use a liquid fuel that doubles as a coolant, offering inherent safety features and efficiency improvements over traditional reactors. Terrestrial Energy has been progressing through the Canadian Nuclear Safety Commission's pre-licensing process since 2016, aiming to have commercial IMSRs operational in the 2020s.

25/27 on the quiz, looks like I need to study more. I will point out that nuclear power plants are not the only construction projects that tend to take too long and go over budget. HS2 among other infrastructure projects are bad for it as well. Having worked on a number of large construction projects I am familiar with the shortage of project management skills in the west. There ate some really good project managers out there but they are definately in the minority. Having stringent safety regulations is a good thing but I have often seen these applied in unnecessarily convoluted ways which at best slows everything down and at worst is downright confusing and leads to errors. Good project management simplifies everything so everybody else can just get on with their jobs.

[@peterfmodel]

Good video. The effort building nuclear is built into its LCOE, or levelized cost of electricity. This metric is used for investors to determine optimum ROI when there are a number of different choices. This value varies by location, type of nuclear reactors considered, local regulation and expected opposition. The value also changes with time. I do find it interesting Germany removed the nuclear LCOE value from most government sites when listing different energy options a number of years ago. I am not sure if its back or why it was removed. When you look at a list of energy options with robust LCOE values for your country or location you can get a good view of what makes sense, or does not. Nuclear is expensive to build, but when you look at LCOE, which factors in cost over expected lifespan, this gives us a more reasonable result. If we focus on base load power nuclear tends to be a better choice than most renewable energy choices. Renewable can only provide base load if it can store the power, which dramatically increases its cost, of if you rely on geographically separated sources, which requires very high voltage power lines to be built. For the latter choice this is typically not built into LCOE. The cost of that depends on the country, but does increase costs. The LCOE changes on a regular basis so you need recent values for your locations. I have seen it move around a lot in the last 20 years, but I suspect its economically viable if compared against renewable, when you want base load. I suspect it could even be a lot cheaper. One point to note the cost of decommission nuclear is normally built into the LCOE, which is not the case for most other energy costs in most countries.

[@salahidin]

the LCoE she mentions is Lazard's and it's 20 years. Lazard moreover, excludes many externalities related to renewables, such as grid upgrade and energy storage. It's useful for investors who don't really care about externalities, and who expect early return on investments. We pretty much wrote the same comment at the same time. :)

[@MattCasters]

Storage costs of electricity will keep dropping as battery technology advances and refinery/production capacities grow. The price drops of solar, wind, and batteries are the real enemies of nuclear and fossil fuel plants. Already millions of households are installing home batteries and the new generations of EV will surely also support vehicle-to-grid capabilities.

[@y0uCantHandle]

Something to note: most LCOE calculations only run for 25 or 30 years. Nuclear power plants run longer than this. When LCOE is extended to 60 or 80 years run time, nuclear plant LCOE is comparatively lower due to other forms of energy generation having to be completely rebuilt. Also, a lot of LCOE for nuclear assume no or little subsidies (in line with current government policies) whereas other forms of energy generations including coal receive subsidies.
