When arriving in Calgary to present at TEDxYYC, Kirk Sorensen was immediately raced from his late arrival flight to MRU, where Brett McCollum had helped organize a lecture.
Kirk gave a brief overview of Molten Salt Reactors (MSR) and specifically Liquid Fluoride Thorium Reactors (LFTR). Half of the time was spent fielding questions from the Calgary students.

[@francisgaliegue6645]

A Nobel piece prize would be appropriate, I believe...

[@darthvader5300]

​@@francisgaliegue6645 The American political establishment does not like it for it will solve one problem which is a big money maker for the contractors who are the biggest campaign fund contributors to corrupt American politicians because it will CONSUME NUCLEAR WASTES ALSO AS A NUCLEAR FUEL. And nuclear wastes storage is a BIG MONEY MAKER for corrupt government contractors and corrupt government politicians. Russia and China already went ahead with their BFMSR power reactors power plants, with Russia using plutonium 239 and China using thorium. More than 200 Russian military underground BFMSR power reactors power plants are already on line and China has more than 500 underground BFMSR power reactors power plants on line. You won't hear or see that on your American and European mainstream media.

[@victorarnault]

I can't get enough of Kirk's lecture.

[@TheBibliofilus]

Kirk is a master orator, his ability to talk about and explain advanced nuclear technology to the public in such a relaxed manor is of unprecedented importance for humanity's future. Hope that some day in the far future he'll be awarded a Nobel prize for peace and/or technology for his work if all goes well and China don't end up ruling the world with this technology.

Thanks for this Gordon. I found it enjoyable, very informative and more relaxed and 'human' than the intense condensed compilations of the three Google Tech Talks. Of course this wasn't edited down to 10 minutes, but in my opinion the extra time taken here to include the questions and interactions adds another, important dimension to the other videos you've done and was well worth the extra time involved. Thanks again.

The new book describing Thorium as the ideal fuel is "SuperFuel: Thorium, the Green Energy Source for the Future", by Richard Martin, which includes mention of Kirk Sorensen throughout. Excellent book.

[@dustinpecora6935]

To hit on 1:35:00 on the security: the upscale security measures are not only to protect spent fuel, but to protect the radioactive wastes such as cesium-137 and Cobalt-60 that are highly radioactive, protect calibration sources, etc which can be used in dirty bomb construction. 10-CFR-37 describes these requirements.

[@brianwild4640]

[@gordonmcdowell]

Dear "T Karlo", when you hop all over KZbin posting "Thorium is not the answer" without raising any points specific to the video you're commenting on, that is called spamming. You need to counter a SPECIFIC POINT touched on in the video. Not just the element itself, which is like saying "gravity isn't an answer to our energy problems". Leave better comments or I'll block you.

It’s almost as though there are people who don’t like advanced technology that can help everyone, who would have thought 🤷🏻‍♂️?

Michael, well he's currently co-founder of Flibe Energy, and wants to build LFTR. When he delivered this material in 2011 he was on the tail-end of trying to simply get anyone to try build it. That was his interest in MSR at NASA... it looked like a great way to power a manned moon outpost, given tough energy constraints on the moon.

Totally captivating....let's do it! A great orator and enthusiast. Thanks.

[@whitepoststudio3947]

Kirk Sorensen will go down in history as a visionary and a prophet of future logical energy development. Even if other energy sources are discovered, Thorium MSRs are ideal for burning up plutonium waste stockpiles and reducing their half life to one that is within humanities ability to store successfully until they decay to safe levels.

At 1:13:00 the question comes up regarding interest in development. The interest would be limited to those who have a genuine concern for the human race, which is not the goal of the .001% who run the world. We have to overcome the .001% before any positive advancements will ever take place.

Actually it's cheaper than coal, so even they're interested once they understand how much money they're looking at.

[@shainemaine1268]

[@b43xoit]

A conventional steam locomotive is also, in a sense, a load-following system. The rate of burning in the firebox depends on the draft. The draft is pulled by exhaust steam from the engine flowing through a nozzle in the smokebox. The draft thus depends on the load, and so does the rate of burning.

[@wildshepherd5918]

Fantastic and desperately needed

[@MrDobrod]

Great idea. Great presentation, Great speaker.

[@williamwaugh8670]

Load Following -- The blowpipe of a conventional coal-burning steam locomotive makes the firebox tend to follow the load imposed on it by the engine proper. So the combination of the firebox and the blowpipe constitutes an engineered load-following heat supply.

[@Reddimus82]

I heard of this at the University I work at. A student was doing a project with this idea. If only the nuclear society would be a bit more enthusiastic about this. It might just work out. Else... Asia will have a head start....

[@gordonmcdowell]

There's occasional online Q&A sessions where MSR notion could be bounced off him. I don't think an MSR question would get enough upvotes or retweets to be noticed without preparation and coordination. I'm not gonna coordinate that, but it is a strategy that hasn't been tried yet, in terms of getting POTUS attention directly.

[@gordonmcdowell]

The "need" for LFTR waste being recycled is pretty high, since some impede reaction, and NEED to come out. I'd take a look at NASA's needs for Xenon (ion drive Dawn mission) and Pu-238 (RTG for Curiosity mission) as prime examples. This is an in-the-USA process. Since PV aren't REALLY being recycled yet it will end up looking like electronics recycling... ship the used up PV waste to China. If there's no heavy rare earths the PV just isn't that valuable. NOT like hybrid car batteries.

[@KarthikSoun]

In India we already have a 300MW Thorium reactor which is the world first working Thorium reactor!

[@kenstech]

I find this all very interesting I ran across this last night and have spent the whole night watching these videos and reading about this issue., thanks for the work you do in this Kirk. I would recommend that you shift your focus from trying to get the government to fund this, to approaching venture capitalists for funding. The government wont fund this because 1: There are too many vested interest that back the politicians (on both sides) and who will push out any competitors. also...

[@spacehabitats]

In physiology we describe a self-regulating, inherently stability system as being "homeostatic". We expect to find this in living organisms but to find this in a nuclear energy source is serendipitous to the point of incredulity.

[@ElevenHymn]

Good presentation, I found it really interesting. When he doesn't need to raise his voice to reach a larger audience (TED talks) his voice sounds just like Tom Hanks' to me. That might be one of the reasons (on top of it being very interesting) why I, knowing absolutely nothing about nuclear energy in general, watched the whole video.

Gordon, I was merely commenting facetiously upon your reply to "t karlo", not on the video. I have been following the efforts of Kirk, and subsequently, your good self, since Kirk's 2009 GoogleTalk hit youtube. Also a big fan of David Leblanc and his DMSR approach. I think IMSR may be what's needed to pave for way for LFTR. A version of IMSR might also make for a good space reactor - no way Musk will colonise Mars using only solar or an LWR. Keep up the good work - you guys are all true heroes.

[@DouglasASean]

I'm not qualified to know if what this guy is saying is accurate but I like the way he speaks - he has conviction. its convincing.

[@zbret]

@yorryyorry Yes - go to energyfromthorium. On the right side is "Java Programs" - download and run your own simulation or join the forum. I can also recommend my site lftrnow which is geared towards summarizing the key points that make LFTR and Thorium great, with links to back up the points. Finally, the quick answer - most products from LFTR decay quickly with fairly little left after a few 100 years rather than 100,000+ years.

[@BTC_DNA]

To the camera person: With respect, getting a close-up of the presenter's head while he is explaining an image on the screen is the exact opposite of what is needed. In fact, it detracts from the presentation. Thank you.

[@NukeMarine]

1. What do you mean by 95% recyclable. There's material used to make the solar cells, cost involved in installation and upkeep and there's a set useful lifetime. Over that time, it generates certain number of gw/hours. Plus, while there are hazardous substances with LFTR and other nuclear powered variants, those substances have been found to be very beneficial to medical and space research. Hazardous is not anthesis to benefits.

[@HerrDrAlex]

On fission products & wastes, the purpose of using 232Thorium is it's 6 neutron captures away from Plutonium, while natural 238Uranium is but 1 away. So, the amount of heavy, long-lived (transuranic) waste is under 1/1000 of what current reactors leave in 'spent' fuel.& there's no spent fuel because the liquid cycle makes just what's needed. Regular fission products also occur, as for regular 235U reactors, but their lives are relatively short & are retained in the salt, unless noble gasses.

Hi Kirk, given the news that the Japanese are pulling out of the construction of a Reactor on coast of North Wales UK. Could this project become Liquid Flouide

[@travismoore7849]

Why don't we use a fast sodium chloride reactor to breed a blanket of thorium salt chlorides that would slow down high neutron flux by boron carbide, graphite or zirconium hydride with zirconium as the salt containment vessel or window? The idea is we can breed more thorium faster for burners short term or fuel existing reactors, while consuming our nuclear waste spent fuel rods. I figure that thorium is more common and cheaper to breed as a fuel. With wast u238 can drive the breeding in the high flux fast salt reactor. So you can do both.

Bret McCollum PhD was the MRU guy who organized the lecture/visit date at MRU. I graduated from MRU back when it was a College (MRC), and is why I visited and asked around Physics dept to see if anyone was interested in hosting a short Kirk talk while he was in town for sake of TEDxYYC talk.

Had there been a water tower on the hill behind the Fukashima power station cold water fed by gravity could have cooled the rods as a back up for the diesel power plant.

[@jimmyb6541]

Mr Sorensen how can I help with this project

[@dnickaroo3574]

There seem to be a lot more problems with developing the Thorium Reactor than I was first led to believe, especially related to Radiation levels that a decent sized one will produce. Only Research and Development sized ones are being produced; with problems still with materials for the containment vessel. Kun Chen estimates that it will take 20+ years for the introduction of a Functional Reactor. Fukushima was a major turning point; and problems from it will continue for many years, the situation being still very unstable. It has turned things back to Coal, Fracking and Natural Gas, and the continuing drop in Oil production. I shudder to think what will happen when Oil output drops below a critical level. That's when there will be a sudden drop in Food production. Either this Thorium Reactor gets built within the next few years or we might as well forget about it.

[@OtakuBozu]

***** no, India's thorium program is based on the heavy-water CANDU reactor design. Solid fueled, water-cooled.

[@douglasdobson8110]

+D Nickaroo Chen didn't say it would take 20+ years for a "functional reactor" He was guessing a timeframe to having a commercial capacity operating reactor online providing power to their grid in 20+ years, there's a huge difference there. What levels of radiation will a "decent sized" one produce?

[@dnickaroo3574]

Douglas Dobson. Yes, I can see that there would be a significant interval between the development of a design for a commercially viable Reactor and when it is built and functioning on the grid. I do not know the exact levels of radiation, but this would appear to be main problem: container materials become brittle. However, technical problems usually seem to solved sooner than one expects; so I feel rather more optimistic that this will occur. I understand that Uranium is a rather scarce resource, with only enough to last another 100 years or so. The solid Thorium Reactor as developed in India seems to be an available technology. Although there are continuing improvements in Solar and Wind Energy, it appears that Nuclear Reactors will be needed to replace Coal, Natural Gas etc to solve the problem of storage; and Thorium-based Reactors seem to be the only ones with assured long-term availability of fuel.

[@tureytaino2785]

+Douglas Dobson It will be even longer if they don't start right now.

[@brianwild4640]

so how did they burn the U233 from thorium back in the 60's yet everyone was safe. yes it will have a high radiation area which no one can go in for a while after it has stopped reacting. just like any reactor. or even fusion

[@VicVlasenko]

Actually, Chernobyl happened because of stupidity of operators, who violated instructions and also didn't understand the processes that go in reactor. Each RBMK can produce up to 1500 MW of electricity and plutonium for atomic bombs. It's not such a terrible design, main problem is that this reactor was originally designed as a small reactor, and when it becomes bigger and bigger - a lot of safety problems appears. I remembered Chernobyl because in 80-s some of USSR scientists also told that RBMKs are extremely safe. They couldn't even imagine, that such shit could happen.

[@robertweekes5783]

***** I don't think anyone was "vaporized" from Chernobyl but it killed about 30 workers from radiation poisoning (from what I heard). It's laughable for anyone to compare Fukushima to Chernobyl, Ch. was 100-1000x worse.

[@NukeMarine]

Ok, I'll bite: 1. What is the cost of LFTR that makes it much too expensive? 2. When has complexity stood in the way of implementation? A passenger airplane is a complicated piece of equipment, it still gets manufactured. 3. If profit exceeds costs, it's economical. Considering such devices are used for more than electricity, it seems very economical. 4. What risks are there that are not present in nuclear powered solar and thermal energies?

[@dhouse1990]

Will there be fluoride air or water pollution caused by liquid fluoride thorium reactors

[@francisgaliegue6645]

Short answer: no. Long(ish) answer: an LFTR does not need a water source for cooling -- and while it can use it, this waste heat can then be used to desalinate water, so that's the first point. As to fluorine gas/fluorides, they are used in the fuel/blanket closed cycle and as such never get released in the environment. If a danger exists here, it's in the manufacturing and transport of fluorine (which never is transported as such anyway), not in the LFTR itself.

[@DuelingBongos]

This video was posted 11yrs ago, and yet the rate of CO2 emissions are higher than ever. Where are all the thorium molten salt reactors? I suspect that, like all forms of zero carbon energy production, the fossil fuels industries and the uranium based nuclear power sector are heavily lobbying congress to obstruct and thorium reactors as long as possible. Since there is already enough greenhouse gases in the atmosphere to make the Arctic Ocean ice-free by the 2030s, which will trigger an abrupt 3 degree increase in average global temperature. That will be game-over for the anti-thorium lobbyists, as well as the rest of the human race.

[@gordonmcdowell]

LFTR specifically hasn't seen much progress. TerraPower is using molten-salt to buffer thermal energy in their Natrium reactor (fast-spectrum Uranium fuelled solid fuel). Moltex is building an SSR-W in New Brunswick that is a fast-spectrum MSR which will recycle used CANDU fuel. Kairos finalized construction (in 2022) the Engineering Testing Unit (ETU) which simulates Hermes their demo unit which they've submitted to NRC. ThorCon will likely build Indonesia's first nuclear reactor, a molten-salt reactor. There's progress but is scattered in western world. The only fast and impressive progress is in China, where they've actually built their MSR. There's been no announcement but most people think it is likely already fissioning. Is a small test reactor similar to MSRE built in Oak Ridge.

You can consume, hold even, or create surplus (breed) U-233 depending how reactor is tuned & operated. Good questions. Takes only seconds to ask them. I don't want to dig up answers which can't be completely accurate, there's material science still to do and components need to be put under neutron bombardment to see how they do. Am not worried about ANY unit of waste measure since E=[MC^2]/1500 is energy density. 4g Th per year per human. Mass isn't being created, so small waste footprint.

@MrDobrod Chernobyl's released radiation killed thousands of people within weeks of the accident. Several months later, zero people have died due to radiation from Fukushima. At worst Fukushima will cause a few more radiation-caused cancer cases to spring up, but the radioactive material fallout released by the accident still pales in comparison to Chernobyl's mess. For that matter, the average coal plant produces more radiation than Fukushima daily, why aren't those level 7 nuclear disasters?

I guess nearly all fission products come out as fluorides. But what about stuff like gold which (I think) eschews collaboration with any other elements? The fission product stream must require a lot of processing, but it sounds like a cornucopia for chemists.

'Remember 95% of the people seem to like their government because of the lies they are told.'

The reason they have security at nuclear plants isn't about proliferation problems, it's because of 911, and the ramifications of that. Chernobyl isn't embedded in concrete; they built a concrete shelter over it.
