- A Nuclear Renaissance. This Molten salt reactor can use ANYTHING! From nuclear waste, to depleted Uranium, to weapons grade plutonium.
It uses molten salt so it can never explode or melt down.
It can be made in a factory and shipped anywhere by road.

Ed Pheil is the principle designer at Elysium. The design is meant to slot into any existing power station you already have too. So if you have a coal power station, just swap out the coal burning part and keep your turbine generators & transformers etc. As Ed has said there is 100s of years of nuclear waste to consume here, so efficiency is not critical. Using less efficient existing infrastructure is fine.
I have to say I was a thorium fan, but consuming nuclear waste has to be the most sensible win. Also as pointed out metal alloys that can handle chloride salts are already nuclear rated. Ones for fluoride salts that Kirk needs, not yet. Thorium will have its day, but we have nuclear waste that needs attention 1st.
Honestly, we really wanted to include more about the founders. Both of them have really interesting stories :)
The problem was that we didn't reach out to them. I think the video could have been much better with some of their quotes and insights.
@@TechforLudditesSira Ed is a really approachable guy. Drop the team a message. Make a follow up video :)
Thorium isn't used because it doesn't generate plutonium so they don't care but I think that a nuclear power plant is actually a pyrophoric generator that uses high energy light to generate heat.
@@mrrolandlawrence That is definitely on the agenda! :)
Thorium can also consume nuclear waste.
"Give them something to like, and then they'll do the work required to understand it. People are smart when they're interested in something."
That is shockingly profound.
This is the fundamental principle behind how I strive to approach teaching. Find out how to make the student interested, and then let their own creativity and curiosity guide their learning.
That may work for consumer goods like smart phones, dust suckers or cars; but I doubt that this applies also for large energy infrastructure installations such as power plants, refineries or chemical plants.
The problem is that people don't like things they don't understand, and if they don't like it, they'll resist learning about it at virtually any cost.
The one sure way to make people appreciate reliable, affordable energy is to take it away from them.
@@phamnuwen9442 Hinkley Point needed 92,5 GBP/MWh to make a utility interested in the investment. How much do you think will the Elysium concept need to get going? How do you define the attribute "affordable"? Even very expensive radio-isotope generators are affordable if there is no other option available.
@@gunnarkaestle I don't know the details of Hinkley Point C, or the EPR, but from a first principles standpoint, a well designed nuclear reactor should beat any other technology by a wide margin. Korea is an example of reasonably affordable PWR deployment. I think they're building them for $5/watt.
I'm not a nuclear fundamentalist though. I'll use any reliable, affordable energy source including fossil fuel if I'm denied the freedom to invest in and consume energy from advanced reactors.
By the way, if you think an MSR is similar to a PWR in some general sense you need to study the technology further.
“Give humans something to like, and then they’ll do the work required to understand it.”

@@jimseldiesel1362 I mean there’s clues right? We somehow dupe people into rebuying the same cell phone every two years. If we could channel that kind of marketing genius into something other than bilking people, we’d have flying nuclear cars by now.

Yes, that was great!
When you mentioned how people are more likely to know a sports score than something which actually influences their lives, I became a fan. I am a book author, columnist, and radio show host. I have said as much, many times in print and on the radio--much to my chagrin. Keep up the good work!

The sacrifice disappears in a puff of feathers and blood.
That's all it took?
This is the deep and specific research based futurist channel i was looking for
Her last point is absolutely true: nuclear reactors seriously need a face-change! Do the chimneys really have to be so monolithic and frightening?
Though I must say wind-farms also give me the willies.
honestly, i’m an architecture major and i’ve thought a lot about approaching this when i graduate. Oklo’s design for their plant was really inspiring, but all that waste heat can be put to good use for the building. like imagine vertical farms that use waste heat as energy and heat in cold climates, or creating small parks around the plant needed per regulations. or, conversely, using the waste heat to power stirling engines designed to facilitate carbon capture. Also, i can see some of these designs being 3D printed with massive 3D printers - and then repurposing the 3D printer as a crane for refueling. then instead of a beige concrete dome - maybe build a pyramid or some other interesting shape instead and mound the earth around it. in other words, celebrating our gift of the atom rather than treating it like a caged dragon. really honestly, the sky’s the limit.
More reactor videos!
I really hope we can stray away from this whole irrational nuclear fear soon
Yes, more such videos, please. You are gift to a parched and thirsty world. Namaste!😄

@@harsha6655 "The house gives paper"? I must be missing something.
In 1979 I was the youngest craftsman working on a reactor at a nuclear site in Washington state. I spent over a decade working on power plants of all types and then went on to work in water and wastewater treatment for multiple employers. Be curious, keep learning. I spent 40 years going to classes and learning about everything I could. And it has been a great adventure to build across North America, from the Arctic Circle to the Sonoran desert.
That’s so cool! :)
@YutbcanskMyBawlz ! You obviously don’t know much about how construction and specialty craft work. I got offered far more jobs than I had time to work on. It might make more sense to you if you considered me a contractor that had an extremely busy schedule and a long list of clients.

Yes, please. More episodes covering progress with all forms of molten salt reactors! I’m really enjoying this channel. A joy to watch! Keep up the great work!
WOW. This was fascinating! I've been watching a lot of videos about upcoming energy storage/energy regeneration and this one by far is the most in-depth one I've seen.
Wow, now this is interesting! Countries like France and UK with older fission plants could do well to move this way, it sounds a lot more viable than waiting for fusion etc
I have just binged a few of your videos and I am really struck with the quality of the info and how it is presented.
You have got a new sub, All best from UK 👍😊
France and the UK and the rest of Europe, need to get their Heads out of the Sand and look at Molten salt reactors that can USE UP most of the Fuel instead of the Wasteful methods they use today that see the need for deep earth containment for THOUSANDS of years, that is absolutely ridiculous, use Molten salt reactors and "Burn" your old waste to Nothing, and get Gigawatts of Electricity basically Free.

But your tax dollars could. Contact your local representative.

Enjoyed your video. Very well spoken and easy to understand. Looking for more!
I would be interested in hearing about Thorcon. They are trying to deploy first of a kind reactor in Indonesia. They want to build molten salt reactors in a shipyard and float them to their destination.
Yes, a talk covering Sorensen’s LFTR work would be great.
I've heard people poo-poo thorium LFTR technology, and I'd like to see something discussing a point-counterpoint. What are thorium's detractors saying, and why? If they're wrong, how?
@@joshuaholton7547 The two main engineering barriers to the LFTR technology are the breakdown of the barrier between the core and the enrichment blanket due to neutron radiation, and the safety risks associated with the removal and chemical separation of the highly-radioactive (but useful) fission products. Neither of these are insurmountable.
The two main political barriers are far worse; the irrational fear of nuclear power on the part of the public, and the requirement for research funding to bring the technology to maturity.
The freeze plug safety system, low pressure operation, ubiquitous fuel, lack of astronomically expensive fuel assemblies (looking at you General Electric..), and the fact that a molten salt reactor has already been demonstrated and shown to be incredibly stable make it a promising technology worth looking into. We really need to get away from high-pressure designs, and certainly far far away from burning stuff like cavemen to make power. Renewables are nice, but we need base-load capacity now. The anti-science folks can cry all they like, it doesn't change the fact that all this extra CO2 we're producing is going to make this a very tough place for our grandchildren to live.
@@MechMan0124 Thanks for the comprehensive response! I wish I could recall where I'd heard it, but an engineer from the established nuclear industry publicly stated that thorium was a dead end that would provide less power and do nothing to alleviate proliferation concerns, and that really surprised me. I mean, if the guy was just sent out to take a dump on an upstart technology, then OK, that's disappointing, but no surprise, I guess. But one would think that, if anything, the nuclear industry as it exists today would be hungry to accommodate new designs and ideas that would help their image and profit margin. What I have seen so far speaks to the opposite. They seem to see LFTR as a threat instead of an opportunity!
@@joshuaholton7547 The LFTR is a lot more complex than Elysium's MCSFR, so it seems likely to be more expensive. The MCSFR core is just a vat filled with a fuel/coolant mixture, there are no moderator structures or control rods. The LFTR has two separate fluids, graphite moderators and (I think) control rods. The fuel processing system on the LFTR is probably also a lot more complex.
Having said that, it's probably a good idea that several ideas are being worked on since you can't tell for sure in advance what will be the most economical solution.
Either way, Kirk definitely deserves credit for educating the world about the MSR.
@@joshuaholton7547 That is true, weapons can still be created using the Thorium cycle. The U233 produced would be contaminated by U232 though, which produces some nasty daughter nuclides that would discourage weapons manufacture and make them difficult to handle and hide (lots of easily detectable gamma radiation).
I agree though, Thorium isn't the end-all be-all of nuclear power. It presents lots of challenges, and we really have no shortage of Uranium available to mine anyway.
The molten salt technology is a separate and proven technology though. Running non-Thorium conventional reactor fuel, molten salt would still offer huge benefits; avoiding the expensive engineered fuel assemblies, operating at safer low pressures, operating at more efficient higher temperatures, allowing "walk-away safe" reactor designs, and giving us easy access to the useful byproducts. The blanket plate deterioration problem goes away with Uranium fuel since there's no enrichment necessary, and uranium nuclides are far more tame to process chemically. Proliferation becomes an issue again, but that's more of a social problem that we need to solve at its underlying causes.
Sadly, most reactors are designed and built by GE. GE builds reactors at a a loss and makes their profit by selling the fuel assemblies over the course of the reactors life. GE is the big (only?) fish in the pond, and switching to molten salt designs means losing out on their "Fuel Assembly Subscription" cash cow. They still profit when no new reactors are built. The nuclear industry doesn't even need big oil to stifle progress, it handles that all on its own.
Thankyou for making this. thanks for explaining fission in an accesible way. I'm now going to read more about this tech, also you have a great presenting voice that makes me listen
Please do continue this series! Absolutely wonderful delivery of some otherwise dry material. Great job.

I like this channel. :) High tech explanations that are easy to understand.
How have I not heard of this Chanel before, you definitely have a new subscriber. Keep up the great work.
I watch a lot of science and technology videos and read some articles every now and then, but this was the best summary of the basics on nuclear power I have every seen by a factor of 2 :)
Very clearly explained and a pleasure to watch and listen to.
Great vid. I hope molten salt reactors are adopted and pave the way to cheaper and more available energy.
Why don't you use renewables and energy conservation and get ten times the results in 1/5 the time for less than half the cost? Oh and no proliferation risk or nuclear waste.
@@jackfanning7952 Nuclear IS renewable. Rain replenishes the Uranium supply in seawater forever.
@@EdPheil Tell me. How did that uranium get in the atmosphere? How did all those man made fission byproducts and actinoids get in the atmosphere? Did a fairy godmother sprinkle them there? If they are renewable, please tell me how you plan to extract them out of the seawater to reuse them. Maybe you could include an estimated cost for the recovery of these elements and how you intend to pay for it.
@@jackfanning7952
Uranium gets into to seawater because rain falls on the ground and dissolves the Uranium oxide out of the ground into the water,which then flows down river to the ocean. In the ocean water evaporates, but thecuranium oxide does not, resulting in increased uranium concentration, until the uranium oxide solubility limit is reached, and is maintained at that cincentration by more rain dissolutiin, and uranium excess precipitating out to the ocean floor. This cycle has been going on for billions of years, and will continue for billions if years, before and after humans exist on earth, unaffected by our use or not.
Not sure what you are talking about. It haa nothing to do with this natural renewable uranium cycle.
@@EdPheil Tell me about radioactive cesium, strontium, tritium, americium, plutonium, iodine and the over 200 fission by-products and actinides in the ocean and scattered around everywhere else. Were they around billions of years ago? Are their concentrations, and even their presence at all, a result of human activity? You know, like maybe after 1940? You know where they came from, don't you? Have they been affected by our use or not? Are the alpha, beta and gamma radiation from them any different than the alpha radiation in the naturally occurring radioactive uranium? Is plutonium any different than the naturally occurring radioactive material (NORM) that has existed, mostly buried by the way, for billions of years? How about strontium (bone breaker) or cesium (heart stopper) or tritium (you know, heavy water)? Did you know that strontium substitutes for calcium in bones, cesium for potassium in muscle and tritium for water? How much of our bodies are made up of water? Maybe we are gaining weight as a society because of all that heavy water. Haha. Do you like that joke? Not very funny, is it? Neither is nuclear. Which do you think will kill us first: the 2200 test nuclear bombs or the 440 nuclear reactors and their nasty, nasty waste?
Is uranium underground or in the bottom of the ocean less hazardous than if it is dug up at a uranium mine and scattered all over the earth's surface in hundreds of millions of tons of ore tailings? How about when they take those still radioactive (and acidic) tailings and pave children's playgrounds and roads in the reservations or use it in building foundations? Is that alpha radiation any more dangerous when it is on the surface like that, right in close proximity to humans, especially children? Or is it the same as when it is on the bottom of the ocean or buried deep in the earth's crust? Is it a little clearer for you now about what I am talking about? If not, I have a million more reasons why I am not pleased with idiots risking all life on Earth messing with something they should leave well enough alone, deep in the underworld. We don't need no steenkin' Pandora's Box.

*pictures of wind turbines* "...you can almost hear the birds chirping in joy..."
I would not say they are chirping out of joy...
Came here to say this ^^
I think that new nuclear reactors, and especially designs that have not been proven by reactor-centuries of service, are the wrong way to proceed. The two reasons are that renewables are cheaper and fuel-free, and the public has already had it with the broken promises and damages of nuclear power. Just keep what we still have running and replace the coal plants with renewables plus storage. it's working just fine in California, it can work just fine in the rest of the US if the politics, corruption and big money can be overcome.
@@acmefixer1 Dude, there is 440 active nuclear reactors in the world right now and about the same number being built and proposed. France is the lead by number of reactors, for which covers ~75% of their electricity used.
And also, last time I checked, some part of electricity in California comes from hidro, some are solar plants (for which either of those effected greatly nature life just to build them) and still buys electricity from other countries...
@@acmefixer1 >new
The tech is 60 years old 😂 you have a preconceived notion and are shoe horning in your ignorance thinking wind and solar are actually clean. Big oil propaganda. Please continue to ignore the 400mw natural gas plants parked outside every single wind and solar farm and, by all means, keep calling it "green." You don't know what you're talking about. Nuclear power is by far the safest and most effective energy source on the planet right now.
Tgatis NOT a picture of wind turbines. Too wide. Just a futuristic building.
Nuclear fission reactors are perfectly safe as long as you maintain them. They have an operational life of 35 years before components start to fail. Keep up with the maintenance and they are the greenest energy type we currently have.

The second atomic age, litterally using up and utilizing the mistakes of the old for the good of all
That’s because people prefer solar panels and hydro.
I’d rather choose reactors that last LONGER & re use the waste. That is IF our government actually invest it rather than being scared. Just don’t build it near the coast so we don’t have Fukushima 2.0.

I'm curious how this differs from LIFTR. One idea Sorensen pointed out was that, if somehow the container broke, the radioactive salt mixture would not sit around killing people, but would bore a hole down into the planet and bury itself because it is liquid and because it is just that hot.

I used to follow a company called Moltex, who were also planning some sort of modular moten salt reactor, but I have lost track of them and how they are doing.
Love the videos, looking forward to teh updates on how these companies' plans are going!
From all I've watched on utube, they're very active. I think they'll have their first reactor in New Brunswick in about a decade or less, but don't quote on the exact timeline. Their technology looks promising also.
@@paulbradford6475 Will this be at Lapreau?
@George Mann I hope your conclusions about the corruption in the UK are unfounded. If true, I'm appalled. I'll say that Moltex working with New Brunswick is going to do some good. This will mean Ontario and potentially Saskatchewan will also get in on the game. See, the traditional canadian reactors (CANDU) used D20, so could get away with simple U238 fuel. The spent fuel is really attractive for reuse. So Ontario will be giving them the waste as fuel, New Brunswick will be operating the plants, and Moltex will be designing it for these applications. Saskatechewan has signed a memorandum saying they're in, but I'm not sure of their role. They host Uranium mines, but that's not actually useful to this scenario. Maybe they want to be customers.
Yes please!! LFTR videos would be great, especially in longer format / more in depth. Great channel, thanks much
This will be my go-to channel for my engineering projects.
A series like this for every different propsed Gen IV nuclear powerplant?
Yes, please.
Or Gen V, like Elysium. Gen IV doesntbrequire closing the fuel cycke, just do better than an LWR, but MCSFR closes the fuel cycke and greay beats the economics of LWR CAPEX & OPEX, instead of just beating it a little. LWR is our fuel source not Elysium's competitor. Gas is our competitor.
@@EdPheil I am 100% an Elysium fan. Y'all seem to be the quickest and simplest path to get off carbon. If I had the dough, y'all would be getting constant funding from me. Of course, you wouldn't be the only one, as my feelings about future needs for energy and nuclear assets are heretical. None the less, you have my vote as a first step in the right direction.
As to Gen IV vs Gen V fission chain reactors, I am still confused as to the nomenclature. "Closing the fuel cycle" means the fuel doesn't go through the core just once but visits it several times in order to have a very high percentage of burnup?
I understand that Elysium deliberately shys away from any chemical processes that could be considered "nuclear reprocessing"; IE, reconsentrating fissile material by removing it from the bulk material. And I understand it as a regulatory necessity. It seems a shame, tho. All those actinides are useful! (Sigh)
In your humble opinion, if it couldn't be Elysium --pretend some jackass had a patent that somehow prevented you to make the Elysium reactor-- what reactor design would you choose instead? Who's the runner up?

2028 sounds so far away, but I guess this is the kind of thing that can't be sped up too much...
Actually, we should’ve BEEN having reactors during the 70’s until radical environmentalist NIXON doesn’t like this idea.
Now we rely on gas and oil, and now solar and wind farms that require a lot of rare materials to be extracted from the mining, which does produce a lot of carbon emissions.
America could’ve been the leading country in the lowest carbon level.
I want it by 2025

According to the official, internationally recognised death toll, just 31 people died as an immediate result of Chernobyl while the UN estimates that only 50 deaths can be directly attributed to the disaster. In 2005, it predicted a further 4,000-93,000 might eventually die as a result of the radiation exposure.
this is much less than fossil fuels killing 4-7 million a year
cool! Please more molten salt! Flibe, Thorcon, Moltex ...
DFR
I'd be very interested in those topics, please and thanks for making this!
Good to see this topic presented to public, especially in such a sympathetic and charming way.
Elysium sounds like the name of a futuristic monopoly
Well maybe they are planning ahead? XD Design better power plants now to corner the market and become that futuristic monopoly by 2100. far simpler to start with the name than to rebrand later
"...not these edifices to brutalism." HAHAHA XD I LOVE IT!
I don't "love it" as "Brutalist Architecture" is excellent Technology. Steel Reinforced Concrete Construction is the best Building Technology for Containment Domes, which all Nuclear Reactors need, as not only does it protect against any Nuclear Accident, it also protects the Reactor from Loonies & Accidents. A crashed aircraft or truck bomb won't damage the Containment Dome, and thus can't damage the Reactor...
@@davidhollenshead4892 I wasn't criticising that, just the language made me chuckle is all.
Thank you for the video! Very well done!!
Very interesting subject, I’m hooked! Keep um coming on this subject area!
Since I first heard about LFTR reactors I have had a great interest in them and have been hoping more research would be done here in the U.S. That doesn't seem to be the case however. I am glad research is continuing elsewhere and thanks for providing explanations and updates. (insert happy face emoji here)
I am highly disappointed in my government (both political parties) for the lack of interest in this.
Some people have got a lot chutzpah for going on about "American innovation" when we have so thoroughly ignored such promising tech.
ahhh you know how "Uncle Sam" is. the rest of the world will spend all tge money and when all the world had done the work and mistakes we pounce
@@joshuaholton7547 Aside from you know, actually pioneering the tech at Oak Ridge, in Tennessee. I think that American monied interests quashing innovation that threatens their rice bowls is the phenom that your are railing about, But then, monied interests would never rig things against public interest, *cough cough* Gamestop *cough cough*

When Elysium is talking about inefficient thermal conversion, they are not talking about using fewer heat exchangers than the core can support. They are talking about using an inefficient thermal to electrical conversion systems. With natural gas there is a choice between using cheap low efficiency fast response turbines, or more expensive high efficiency slow response turbines. Elysium proposes that, since the actual nuclear core only accounts for 15% of the total cost of the power plant, minimize the total cost of the power plant by using inexpensive low efficiency fast response turbines.
One of the problems with using natural gas to back up solar and wind is that they need fast response to offset the intermittent nature of these renewables. This means replacing slow response high efficiency (up to 60%) turbines with fast response low efficiency (less than 40%) turbines. What this means is that, depending on the percentage of total energy that can be supplied by the renewable energy source, increasing renewables can lead to an increase in carbon emissions because of the change over from high efficiency turbines to low efficiency turbines. Backing up solar or wind with gas can lead to at least a 66% increase in the amount of CO2 produced per kwh in the natural gas backup power plant.
For a spent nuclear fuel burner, this is not an issue. Indeed, the way Elysium sees it, the less efficient the turbines that generate the electricity, the more SNF that is burned for a given amount of electricity. Thus, using fast response low efficiency turbines not only reduces total plant cost, it also results in SNF being consumed at a faster rate.
The one flaw I see in Elysium's current strategy is they now intent to use SNF as a feed stock as well as for start up of the reactor. I feel that thorium should be used as the feed stock. The problem I have with using SNF as the feed sock is that, with the exception of reactors located where the SNF stockpiles are, this would involve transporting SNF cross country.
Excellent description and argument. I agree with using Thorium as an initial fuel because the designers know exactly what they using. Spent reactor fuel is unlikely to be as uniform.
@@gregwarner3753 Thorium can not be the starting fuel. Thorium in non-fissile. With regards to uniformity, that is the point of starting with SNF. Elysium realized that, if they start with high assay low enriched uranium, they would have to design a reactor that could start with this HA-LEU and transition to consuming SNF as the HA-LEU was consumed. By starting out with SNF to begin with, the reactor can be designed to burn a less variable mixture throughout its operation.
My argument is that, while they should design reactors that will burn SNF at the sites of SNF stockpiles. there are both logistical and political problems with transporting SNF off site. Therefore, thorium should be the feed stock to these reactors to produce the U233 that can be transported relatively safely off site to start up off site reactors. Indeed, using inefficient thermal to electrical conversion systems would be even more desirable in this case because, this would optimize the amount of thorium being converted to U233.
Of course, I also disagree with Elysium's plan to leave the reactor sealed for 40 years. For one thing, the NRC requires that a test reactor be operated for the planned operational life of the commercial reactor before they will approve commercial deployment. That means, if Elysium is going to operate these reactors for 40 years, they will have to operate the test reactor for v40 years before the NRC will license commercial reactors.
The proper way to do this is to start with reactors that will operate for 7 years before being shut down and refueled. The test reactor would then have been in operation for 14 years by the time of the first shutdown, so the commercial reactor can be relicensed for 14 years of continuous operation before refueling. When being refueled, the reactor can be refueled with a fresh batch of SNF.
There are certain problems Elysium wil face, beginning with the limited supply of plutonium stockpiles. As I understand the situation, there is only enough plutonium in the stockpiles to fuel about 20 Elysium reactors. After the plutonium stockpiles are depleted Elysium will have to, like Flibe with their LFTR49 SNF burner reactors, remove SNF uranium to get a concentrated enough mixture of transuranics to start up a reactor. Of course, the NSA requires that each new fuel mixture be tested before bein used, so Elysium will have to start up a test reactor using this more highly purified SNF before they run out of plutonium. Indeed, if off site reactors are to be started up with uranium, Elysium will also have to run a test reactor using this fuel prior to commercial deployment.
I understand there are about 150 SNF stockpiles nationwide. If Elysium starts with installing one MCSFR at each of these sites, they will be able to install about 150 reactors before they have to install any off site. The uranium extracted from the SNF stockpile can be sent to enrichment plants, replacing natural uranium. The uranium from the spent core can be processed separately at the same enrichment facilities, and prior to licensing of commercial MCSFRs started up with uranium containing U233, this U233 enriched uranium could be used in LFTR23 reactors. possibly in India. Eventually, this U233 enriched uranium coyld be used to start up off site MCSFR reactors.

@George Mann The US should not go with one individual technology.
Personally, I think sodium reactors are one more dangerous technology. But what do I know. I bet a friend $20 that the first space shuttle would either blow up during launch, because of the O-rings, or burn up during re-entry because of the ceramic trials. I lost $20 on that bet, but was glad I did.
The molten salt storage loop is not unique. Moltex has a system they call Grid Reserve. Their idea is to use solar salts from the concentrated solar industry, indeed they propose to use the exact same turbines as the concentrated solar industry. They plan on, later on, switching to thorium salts as a coolant, so the coolant can double as a breeding blanket.
Bill Clinton was the most honest President we have had post Kennedy, which is not to say he was the best. The best candidate we have had since Kennedy was Big OIl Pappy Bush. Clinton did kill the molten salt reactor program, but not because of big oil. It was due to the influence of the light water reactor industry that the molten salt reactor program was killed.
While I claim that Clinton was the most honest President, that does not absolve him of blame for major screw ups, including deposing the elected leader of Afghanistan to install the Taliban, to appease the rich who were being harmed by the elected communist. And cow towing to the light water reactor industry is just as bad as doing so for the oil industry.

No LWR ooerated for 100 years, yet NRC is working on the licensing needed.
Wow you covered a lot. Excellent job.
I very much enjoyed this video. I played it at a lower speed to absorb everything you were saying. The molten salt reactor idea is what turned me on to CZcams actually. Kirk is the founding father of the new movement from old ideas of course.
"An offering to the turbine fairy..." I love it. I wish I'd used this when teaching the subject.
How come that every time I watch a video on SMRs no-one mentions the CAREM that is the first design of an SMR and the ONLY SMR currently in construction?
Because unfortunately we Argentinians stopped being technologically and geopolitically relevant to the rest of the world during the last 3 decades. CAREM is a nice design, a downscaled version of NuScale's if you will (i.e. a PWR with passive natural circulation for decay heat removal) and I believe the conceptual engineering was done by CNEA back in the 80s.
Let's see if construction finishes before the end of the decade though (fiscal restrictions notwithstanding).
Hey Manuel, this is a Fast Molten Salt Reactor, not an SMR.
I’ll definitely look into CAREM, now that you’ve mentioned it. Thanks for the comment! :)
@@TechforLudditesSira MCSFR Can be a SMR or a Large Moulsr Reactor, uprateable without buying a new reactor.
I love watching your videos. I have learned so much and you make it really easy to understand. Thank you 😊
Very informative, thank you. Looking forward to more.
