How do nuclear power plants work? - M. V. Ramana and Sajan Saini

[@coldsun1]

These are mostly challenges of outdated nuclear technology. The newer technology has solved a lot of these problem. The latest designs of nuclear power plants can actually use the nuclear waste from the older nuclear plants.

[@lighto2240]

ًThen why did the use of nuclear power plants to generate electricity has decreased from 18% to 11% in the last 20 years

[@seanjordan6549]

There are things called public opinion, and money. I hope that answers your question.

[@coldsun1]

Lighto The reason there has been reduced nuclear power usage is because the irrational fear of all things nuclear. I think they kind of associate the danger of nuclear bombs with nuclear power. Since most people don't like nuclear anything, there is pressure to shut down all current nuclear plants and switch to alternate power sources which caused the decrease from 18% to 11%. Also most governments are using old nuclear powerplant technology which aren't as safe or as efficient. Most operational nuclear power plants were created 20+ years ago with old technology. the technology they used was severely outdated before they even started. Look up thorium reacters. From what I've read they seem to be the future. Also there are working designs that actually use nuclear waste for fuel.

[@gusstavv]

You can look up for Thorium reactors and they are not fully developed. And the reason governments are not interested in this safe and clean nuclear power is because it doesn't produce weapon-grade plutonium. At the end, everything is reduced on the war economics system we love to have.

[@whykhr]

The reason is Big Oil buys all the politicians, all the media, NGOs like Greenpeace, the Sierra Club, lobbyists, institutions so of course nuclear is in decline. Corruption, crony capitalism that is how our government works. Man people are just so naive.

[@easportsforever]

They completely ignored the fact that the "waste" Plutonium-239 produced from the transmutation of Uranium-238 in the nuclear fuel rods can be filtered out and used in fast breeder reactors as an energy source. There are several of these in the world currently. In addition fast breeder reactors don't need moderators to slow down neutrons and the fuel is self-sustaining in a sense because the neutrons released from the fission of Pu-239 can be used to transmute U-238 into Pu-239 again.

[@metazoxan2]

It skips a lot of important explanations though. Like how modern plants have many more safeguards to prevent a containment breach (the disaster in Japan a few years back was because it wasn't built to code to withstand earthquakes which cracked containment and then a Tsunami washed the material out to sea). Or the fact that material with long enough halflives are harmless and emit less radiation per second than what's naturally present around us everyday.

[@paulswanee5855]

Yes there are challenges, but there are also solutions to the challenges suggested here. For example @3:14 they describe the fission rate of being too low. What is occurring is that U-235 has too small of a neutron cross section for uranium 238 to split the parts. However there is a solution to this problem. Instead of using U-238 which has 5% probability of fission production, you can use Th-234 (thorium) to transmute U-233 which has an 80% probability of fission production due to a significantly larger cross section. This is why thorium reactors do not require as much fuel, and why they don't produce as much waste as the common reactors of today.

[@gusstavv]

Thorium reactors solve (almost?) every problem of actual nuclear power production. But they are too expensive to be implemented... or even mentioned.

[@paulswanee5855]

+Gusstavv's Stuff Nuclear power has never really had a problem with production. By far nuclear requires the least amount of fuel of an energy sector. Even the issues of uranium supply can be solved by engineering cost competitive harvesters to pull uranium deposits from the ocean. The major issues of nuclear have always been public reception of safety and economics of design. I believe if you factor in all the potential reductions in cost combined with reductions in come regulations you can make thorium reactors cheaper than LWRs and more competitive with natural gas.

As a future nuclear engineer, I give this mostly a B+ on facts, which is actually a cut above the rest of internet videos on nuclear power :D Couple of minor physics details were off (it isn't that water doesn't slow down neutrons enough, it is that it absorbs to many that we need enrichment!) One of the things missing, and this is hard to do with a primer like this, are other reactor types. See the one mention in the video is one of dozens or ways to do nuclear. It happens to be one of the most popular designs, but not the only design and many competing designs can resist meltdown dangers, recycle spent fuel, ect ect. Basically, most of the downsides could be engineered away if we had the desire to. I know that is what I am in school for!

@@biswajitpramanik3426 Per unit of energy produced, coal power causes over 300 times as many deaths as nuclear power (and some estimates even say over 1000 times as many deaths).

By your logic, we should immediately shut down all power plants and engines that run on coal, oil, and natural gas, because they aren't foolproof! In fact, the deaths per unit of energy produced caused by solar, wind, and hydro power are pretty much the same as for nuclear power. Shut all of those down too! Not foolproof, after all!

[@mikeall7012]

saying this is biased, is an understatement. it leaves a lot of very important qualifiers and caviates on modern countermeasures and engineering which prevent such issues. new reactor deaigns deal with most of these problems. in addition, making a bomb from light water spent fuel is incredibly difficult and messy (meaning easily detrctable). i hate it when these ted eds speak with an agenda, instead of presenting facts

[@ndog37]

In a way they try to be fair. Clean Nuclear power like clean coal can be achieved through breakthroughs in modern tech, new design and reprocessing but politics and bad past experience make it hard to sell.

[@Apostate_ofmind]

Hah no they dont. and making a bomb means having a drived mind behind it, and we know thoose stop at nothing.

[@mikeall7012]

wow, im glad you backed that up with a lot of facts. light water power reactors use a long fuel burn, for increased efficiency, which builds pu240 and other non undesirable components into the spent fuel. these products cause the fuel to be almost impossible to create weapons grade material from. in addition, the process required for reprocessing and enriching the spent fuel would leave a large industrial and radioactive foot print. furthermore, seperating pu239 from pu240 and pu238 is unbelievably difficult and has never even been attempted. i work in the field and tire of fear mongering, when it comes to modern nuclear technologies. modern reactors absolutly address the meltdown concerns by making the cooling systems passively safe. that means they can be cooled no active components, such as electic pumps ans diesel generators.

[@lokegustafsson247]

Harry Ferrari That is actually an amazing way to summarize much of the nuclear power debate.

[@HobbesHobbiton]

Key word there; "deal with most of these problems". Sure, they may be safer but are they still really better? You still have nuclear waste that is a huge problem, as it will keep accumulating and the chance of it polluting the environment increases as well. (If you think we should just launch it into space, it would be even more expensive, watch Kurgestats video on it) And even if you have a very safe reactor, accidents do, and have happened.

[@zodiacfml]

It is sad to see it go down as this kind of power generation has the most potential using cutting edge science. I've read some developments in using the plutonium as fuel, where the nuclear plant doesn't consume fuel but creates them. I never heard of it again these days.

What the fuck. This was such a biased piece and I am disappointed in it. They didnt talk about how we are designing nuclear reactors to run off that waste. They didn't talk about how nuclear power plants 'leak' less radiation than coal power plants. How nuclear power plants are safer for humans and the environment than coal power plants (this includes the major disasters). How about how we would still need to process those radioactive materials because many industries rely on the byproducts of the refinement process to get things like Yellow Cake and Depleted Uranium. We have learned a lot sense Chernobyl and the industry has banded together to make nuclear power MUCH safer because our entire industry is at risk. Fukushima may also be brought up but let me remind you that they recovered much of the land around the Fukushima power plant (and moving closer each year) and the radioactive levels of the ocean is almost down to its natural levels. Nuclear isnt perfect, nothing is, but the world is far away from being able to function without power plants that have a stable source of power. Nuclear is the safest type of plant for that job. Dont take my word as the gospel, go and look at the facts for yourself. Just remember that nuclear is not the terror that the media frames makes it out be. I am sad that TED-Ed has sunk down to this level also.

They also didn't talk about the fact that long half lives are safer. What most people don't understand is that radiation isn't just instant death it's about how much you're exposed to and material with a longer half life emits LESS radiation per second. so material with a half life of 20,000 years is generally pretty safe as long as you don't just litterally eat it and even then it might not do too much.

Nuclear power is high-risk and high-reward. To those who herald it as the solution to climate change and the use of fossil fuels, I believe it'd be better if we balance out the usage of nuclear power vs renewable non-nuclear power. That should hopefully give us enough time to fix the problems associated with fossil fuels and find ways to manage long-term nuclear waste. Afterwards, we could easily rely on nuclear power and sources such as solar and wind power for our needs (maybe even fusion power if it ever becomes a reality!) Here's one long-term nuclear storage solution that's being tried out by Finland: en.wikipedia.org/wiki/Onkalo_spent_nuclear_fuel_repository

Nuclear power is no where near high risk. The chance of a meltdown is currently required to be 1 in 10 million, which is considered statistically improbable. Even if a nuclear reactor melted down, they are currently built to withstand a melt down and are extremely safe.

1:54 I’m dying 😂

loolololololol my brother when he dies in minecraft

Honestly, I wish we have more budget to make Nuclear power safer and more acceptable. It just seems like the proper way to progress to the future rather than continue with our current one which is slowly ruining us and being spent completely.

The vault dweller coming out of the vault at the end should be wearing a vault 13 suit. 13 was the main character's vault in Fallout 1.

Gorgeous animation as always!

I was waiting for fusion reactions to be brought up, even thorium

[@king89053]

The hidden references made this video soooooo enjoyable to watch

[@josef5341]

so ... many .... references... so.... awsome.

Congratulations Ted, You managed to fascinate me and scare the hell out of me.

YourPalDaniel this video exaggerates and depicts mostly the negative. Use multiple sources for more reliable information.

Humans need to start thinking in a more recycling and reusing system. Nuclear Power waste products could be recycled into nuclear medicine, if only we have the technology and resources. By applying this type of thinking we will lower a lot of the obstacles associated with nuclear energy, and see its true potential.

Fallout Reference in Ted-Ed video = A sick science lesson

[@hitheshkarthikeya9055]

use thorium

[@almahnak12]

no u

[@Fishtyi]

you don't understand how much this helped me thanks you so much

1:20 I just went swimming, and now I glow...

I love how the Neutrons just goes zooming past the Uranium Nuclei like a extroverted friend with a introverted friend just waiting for them to notice they're standing there. 3:34

Biggest problem is people's fear of nuclear energy

[@maxrockatansky3710]

Nice to learn these things as I only work for stress analysis of pipes near the turbine and have no idea what happens inside reactors.

Why are we sleeping on my boy Thorium ?

[@CoinuMedus]

I’m so used to the typically striking, one-line conclusions of Ted-Ed videos that this one kinda left me hanging.

What I Gained From This Video: "Water is rad, dude"

[@arkamitra4735]

A lot of careful engineering goes into designing a nuclear power plant. fuel rod has many levels of barriers (like clad, inner and outer containment). For LOCA ( loss of coolant accident) which is pretty improbable to happen, they have ECCS ( emergency core cooling system). Every plant has rigorous analysis and safety reviews before commissioning ( like fault and event tree analysis of the whole system). Also regulatory bodies keep a close watch on whether the safety protocols are properly followed or not. Also problems of spent fuel are being addressed by vitrification, storage bay and also accelerator driven subsystem ( which can burn the long lived fission product to turn them into short lived daughter products). So, many apprehensions conveyed by the video are not very substantial and if we look for a better and greener future, nuclear energy is one of the best possible options that we have.

That nuke scene at the end hit like a truck
