LFTR (Thorium-MSR) - Kirk Sorensen of Flibe Energy @ University of Tennessee, Knoxville

[@gordonmcdowell]

This video combines Flibe Energy animations with Kirk's University of Tennessee presentation (where Kirk was showing the Thorium Fuel Cycle animation as part of this talk). Flibe's original fuel cycle animation is here: kzbin.info/www/bejne/g6eYdqmlpJ2hp5Y and I'd also recommend checking out Flibe's animation on Targeted Alpha Therapy: kzbin.info/www/bejne/oqXMhmiQir1-eac Kirk was extracted from the UofT video using DaVinci Resolve Studio's "Magic Mask" feature. I've been taking multiple stabs at this, and you'll see 2 different approaches used in even just this one video. Am continuing to experiment with it... there are dozens of KZbin tutorial videos showing a variety of approaches. Most non-intuitively to me, there's a "Fusion" tool and a "Color Correction" tool which both offer "Magic Mask" with different feature sets. DaVinci users on Reddit recommend that the "Color Correction" Magic Mask has more features and what most people tend to use. Tutorial videos tend to show one or the other, and never seem to compare pros/cons of either approach. While the bigger Thorium project remains in Adobe's Premiere Pro, I'm hoping to one day turn off that subscription and only pay to use PPro when needed. This DaVinci Resolve Studio was a bit expensive as a one-time purchase, but would easily pay for itself within a single year's use. (Black Magic who created DaVinci Resolve don't survive on software sales, but rather hardware sales. DaVinci exists to support their hardware business.) If you'd like to support my own communication efforts, this is my preferred mechanism: www.patreon.com/thorium ...I don't have an ETA for next large narrative release, but that is what I basically use Patreon to fund. These smaller one-off videos are components used towards that end.

In effect, you are wishing us all that success, if I may. I sometimes imagine what would happen - not as in a movie but in very real terms - if someone were to come up with a low-cost, high-efficiency, reliable, clean, scalable energy system. It is the stuff of movies (and conspiracy theories), too, of course, but I imagine a bullshit-free demonstration of something like this working, and the screams and gnashing of teeth in the biggest energy companies and stock market.

No proof or even evidence it’s lost or hidden.

There has never been any technology like this discovered and proven to be fusion or fission capable.

[@GreezyWorks]

Gordon, did you know? Caesium-137 can be transmuted to stable Barium 136 & 137 by proton bombardment (~13 MeV) from an accelerator. In the process, a gamma ray and a neutron is released, which could be absorbed by Thorium, for instance. Even this fission product has more to give, if used creatively and treated with respect. Keep-up the good work.

[@stanm25]

I have been following up on this for quite some time particularly his design. I’m aware that he uses graphite moderator and that the majority of the vessel will contain graphite. I do have a few questions though. How long will the graphite moderator last before it needs replacing, or will it be the entire housing with the graphite inside that is going to be replaced with a new one? Also what do they plan to do with the vessels containing the used graphite? Can the spent graphite be extracted with some items being recycled while others safely disposed of?

[@alanmcnaughton3628]

Obvious question. Do ceramics have graphite as a reinforcement mechanism?

[@dalesplitstone6276]

My nephew works at a solid fuel nuclear power plant. He revealed that the operators are looking forward to installing an MSR on site, but not a thorium reactor. They want a waste burning MSR. They do not obect to having a thorium blanket in which to breed U233, indeed they recognize the potential of U233 being denatured with U238 and used to fabricate fuel rods, as an alternative fuel for their current reactor, but the main goal is to burn the waste from their current reactor.

[@StarlessSky2000]

Kirk talked about an SNF burning MSR with a thorium blanket, the very reactor you are describing in the video. It’s a very appealing option both for reduction in waste profile and for the potential to build LFTR’s later. Unfortunately, a number of plants and utilities I am familiar with have said they arent looking to do anything about their waste problem because no one is making them do anything. You should encourage your nephew to reach out to Flibe if there is genuine interest in a waste burning msr.

[@EdPheil]

Exodus Energy is specifically focused on recycling Slightly Used Nuclear Fuel from LWRs, CANDUs, & thermal MSRs, SFRs, LFRs, or open cycle MCFRs, like TerraPower's. Just not TRISO, since it is not economically recyclable, yet only reaches 10% burnup at most, leaving 90% unused.

[@Scientist538]

any adoption of molten salts is beneficial

[@DanMoridin]

Wait, so you can essentially recycle and thus mitigate the hazards of long term storage of nuclear waste?

[@MatthewHolevinski]

I love the fact that making electricity is literally the least valuable and least interesting thing you can do with molten salts. As a species right now, targeted alpha therapies has got to be one of the most important things we could possibly do right now. That would be game changing at a global level. There is no reason we should be having a bunch of children die right now because of something stupid like leukemia.

[@EdPheil]

China has a small water reactor at the CAEA, designed for installing in hospitals with fast & thermal neutron & boron alpha therapy at hospitals. This reactor was in use treating patients when I saw it.

[@benthere8051]

I love listening to Kirk Sorensen. He has a wonderful command of thorium and its nuclear chemistry. I wish that the DOE would get more interested in developing nuclear energy. We need a second Manhattan Project directed at developing ways to convert thorium into energy generation and the chemistry that can use its high heat to make fertilizers, distilled water, manufacture fuels, and do thousands of other chemical processes. I think the final step of using thorium as a fuel will be as a liquid salt.

[@williamgrimberg2510]

Kirk is and has been one of the most influential people in the thorium community for years and l have learned a lot from his podcasts that I try to pass on to others which sometimes can be difficult because most people don’t understand the technology and or don’t want to take time to learn about it . Pretty sad since just about everything they touch needs some form of energy which keeps going up no matter where it’s coming from because of all the different suppliers. Until TMS Reactors finally come online ,we will have a lot of JP Morgans keep trying to hold it back all for their own mighty bucks and not the people as a whole .

Glad to see inside the protactinium removal step. Was the main thing I didn't understand about the process. So its got molten bismuth in the cell. Is the bismuth going to react with the floride at all? Interesting that bismuth and FLiBe have very similar melting and boiling points. approx 300C melt and 1500C boil.

[@tbix1963]

Thanks for sharing your thoughts, ideas and videos. Always nice to see a new video posted concerning this technology even if there is very little new concepts being portrayed. It’s important to keep the information fresh so new people can learn of its benefits. A question I’d like asked is concerning the xenon production during operation. I know that in current reactors they operate to minimize xenon production. Can the fuel cycle be tuned to maximize xenon production and how much is created during operations. Could enough xenon be made to use as a propellant in a space craft by the reactor that is powering the spacecraft.

[@gordonmcdowell]

I don't think there's much influence at all over how much Xenon is produced per-fission, but with liquid fuel we have a choice between keeping it all in the flux and deliberately letting it absorb neutrons, or to move it from out of the flux and retain all the Xenon which is created.

[@tbix1963]

@@gordonmcdowell thanks for the reply, my personal experience was as a system operator that provided transmission for a nuclear BWR. Often had to deal with limitations on plant due to xenon and the need to remove it prior to increased loading on the plant. Have been an avid fan of various forms of power generation including space technology amongst others. Recently watched an interview with Elon Musk in which he said Nuclear really wasn’t an option in space since you still need a propellant that it can’t provide. And me thinking is there more than one element called xenon? Seem to remember seeing it as a possible propellant in electric rocket engines and that it’s also made in nuclear reactors. Curious that I know something that Elon either doesn’t or doesn’t mind pretending not to know.

One of the arguments against molten salt is the chemistry getting out of spec and fissionable material settling out of solution and causing unplanned excursions. Is this an unfounded risk?

[@generaljackripper666]

The chemistry doesn't change unless you change it.

[@no_rubbernecking]

While I am neither physicist, chemist, nor nuclear engineer, and haven't studied in these fields in depth, I know that the MSRE, running between June '65 and December '69, produced over 90 GWh thermal (324 TJ), the equivalent of running at full power continuously for a year and 3 months, and to my knowledge never had an excursion. It generated first with ²³⁵U, and then for the last 1½ years it generated with ²³³U.

[@Rob_Moilanen]

​@@generaljackripper666exactly, the dude is asking the same thing the others have... but to answer you, it is an unfounded risk, it's too hot physically to get at the fuel (the fuel runs at 650 celsius), and it's too hot cause the release of gamma bursts it would kill you with to get at it....

[@Rob_Moilanen]

​​@@no_rubbernecking it has since had all the actinides taken out of the salt solution and put into storage at the Y-12 plant storage vault....the salt still remains in the drain sump at the MSRE building....

[@mntbighker]

@@generaljackripper666 I f you study the LFTR design you see that it's a fairly advanced chemical plant. Chemistry is continuously monitored and changing. LFTR practically has a liver and kidneys to keep the fuel salts stable. Thorium is added and things are removed/recycled. Physicists have argued that if the fuel chemistry goes out of certain tolerances the fissionable materials can settle to the bottom of containment causing an unwanted criticality. It's rarely discussed by fans of the technology. So the question becomes, is someone being alarmist? Or is it a dirty little secret that we will "figure out when the time comes"? I've heard arguments both ways. I have never heard Kirk mention it.

Is it possible to have a fissile materials processing plants next to these reactors, where they can transmute long lived isotopes into much shorter lived isotopes, in order to minimize long term storage?

[@philipyoung7034]

My back of the envelope calculations determine that “burning” nuclear waste in a thermal reactor is painfully slow. The transmutation percentages of the 7 long-lived fission products in a CANDU going full blast (neutron flux of 10¹³ n/cm²/s) for 20 years are: 27% for selenium-79; iodine-129 17%; technetium-99 13.8%; pallad­ium-107 5.67%; caesium-135 5.10%; zirconium-93 1.4%; and worst of all tin-126 0.06%. The neutron flux in a LFTR may be higher, increasing the rate of processing.

[@MrDhalli6500]

So the last question that was asked was about I&C instruments and corrosion. When you say corrosion are you talking about the kind of corrosion where salt water eats away at the metal parts of a ship with all the pitting and removal of metal? And that corrosion would be inside the pipes of the reactor where the molten salt is flowing where you can't see it unless you remove the pipe and look down inside of the pipe.

[@lexpox329]

Yes, as I understand it that what is going on. The acoustic monitoring is interesting though, because that would let you know when a part is reaching end of life without having to take it apart to look. Then once its past tolerance, then shut down the system and rebuild the requisite components and start it up again. If the downtime can be infrequent like once a year or something then it could be viable.

[@MrDhalli6500]

@@lexpox329 I agree the acoustic monitoring is like an ultra sound very non invasive no need to break the system open. but does the system need to be shut down because of heat issues while doing the acoustic monitoring? or can they do it while the system is running @ normal operating temps? 600 to 800 C seems a bit hot for me to get to close with an acoustic monitoring device, I'd hate to have to wear a baked potato suit to get the sampling done.

Great chit chat. But scale it up and having a workable project would be better. What is the time frame for a working thorium MSR ??

@timmundorff2354 So Tim, what is the "time frame" for "your solution" to be "scaled up" for a viable "project" or potential "iteration": or would that be "sprints"? Moving on, and slightly sideways purely for example because I am not a fan of Gelato: It seems that team evaluation towards the progress of a sprint associated with fusion can be elusive. It is not uncommon to hear statements covering a multitude of iterations going forward that fusion is 8-10 years away. It is always 8-10 years away. For those involved; data is good. Research, iterations, trial & error are to a large degree removed from real world everyday markets. Some might give credence to the geo-political military-industrial influence directed at certain areas of scientific endeavour. There is a need for the achievability and realism of fusion and fission. Those global points are patently obvious. Thus the use of "scale it up and have a workable . . . ." seems to lack some sort of clarity for you. A better description could have been; when will the sum total of agile methods presented in this specific vid as outlined by Kirk result in a economically/financially viable power plant delivering energy to the national grid ? There have been very few experimental reactors and even less power reactors using the Thorium fuel cycle. Some individuals involved in nuclear research & development think Thorium of good, others do not. I congratulate all individuals working towards improving energy supply via next generation nuclear research. The hope is that SMR designs can be part of the energy mix sooner; rather than perpetually viewed as iterations going forward.

I like how you think it's possible to just take out a permit and build something of this nature. There's 50,000 hoops to jump through, even without the government agencies throwing more hoops at you every day of the week.

Animations where awesome dude

[@robertbrandywine]

Based on a video I watched a couple of days ago, we should consider making a shield out of Tardigrades!

[@chrism.1131]

Are you still planning to use super critical CO2?

[@upresins]

That decay of Pa to U233 releases energy, doesn't it? In what form would it be? Hope not Gamma

[@bobthebomb1596]

A hell of a lot of gamma yes, that's why the idea of someone stealing it is so unlikely.

[@upresins]

@@bobthebomb1596 So the containment during this stage would have to be somewhat excessive, I guess

[@bobthebomb1596]

@@upresins He does talk about being able to handle it, so "excessive" might not be the word. It would certainly ruin your day (all of your few remaining days in fact) if you tried to remove the material without proper shielding though.

@@bobthebomb1596 🙂 Thanks

[@M0rmagil]

Pa 233 -> U233 is the result of beta decay.

So, why don't we have these reactors now?

[@chapter4travels]

Because the overall system is much harder to do than they first thought and the regulators don't have a clue how to regulate it.

[@markfinley3703]

According to John Madden, "When the question is why, the answer is usually MONEY."

[@chapter4travels]

@@markfinley3703 Flibe chose to develop its reactor in the US, so they are working under the NRC regulations. If the NRC approves a reactor design then no one will be able to afford it. NuScale just proved that.

[@stanmitchell3375]

I read about it @ 1975

[@Sonex1542]

I totally support this work. But for FS... Why isn't MUSK or GATES funding this work?

Gates is funding Terrapower.

One man trying to save the world, I have to question why there hasn't been any major government support into these reactors. Especially with the feigned concern over climate change. I would like to see an energy future without scarcity, I do hope this technology will function one day. Solar and wind are not the answer.

[@john3pq-ss8su]

Simple: Westinghouse and GE. They have all the fuel contract for the current nukes and they make bundles off them. They take every opportunity they can to delay and obstruct new nuclear technology for fear of the world discovering that there's a much better.safer and tremendously cheaper alternative. And they have LOTS of lobbying power & influence. When your business is buggy whips manufacturing, you don't want cars on the road. IMHO.

[@stanmitchell3375]

I could invest once the first reactor is going, or the nuclear waste recycling is proven
