LFTR in Five Minutes – Is thorium better than a silver bullet energy solution?
ByRod Adams October 12, 2011July 5, 2020

…m safety. In a perfect world, the United States would develop both IFR and LFTR reactors in parallel. IFRs would complement LFTRs and could potentially be valuable for reducing some spent nuclear fuel issues (Minor Actinides) that LFTRs operating in a thermal neutron spectrum can only resolve rather slowly over the span of decades. Unfortunately, the history is that Sodium Cooled Reactors has been the design that (without good technical justificat…

The Atomic Show #121 – LFTR with Kirk Sorensen and Charles Barton
ByRod Adams January 6, 2009December 15, 2022

…rton and Kirk Sorensen for all you two have done to get the word out about LFTRs. I first heard about the LFTR from Alex Canarra, PHD, at a Sierra Club meeting, who I have learned a lot about this from since. Also, I discovered lots of web sites with information about LFTRs too. Hey, I never heard of a LFTR before. Since then, I have sent out hundreds of letters to my State and Federal politicians, newspapers, investors, Philanthropists, Investors…

Kirk Sorensen – Why didn’t molten salt thorium reactors succeed the first time?
ByRod Adams December 23, 2011July 16, 2020

…metimes extol the air-cooling advantages of high temperature reactors like LFTRs, (HEAVY)LFTRs would benefit greatly from water cooling to help keep components of manufacturable size. Even with water cooling, it would probably be necessary to build turbine halls with multiple S-CO2 turbine-generator power-blocks connected to the single (HEAVY)LFTR. The concept of a Large Modular LFTR composed of multiple 1.6 GWe LFTRs mounted together is possible…

LFTR – Kirk Sorensen Visits a Tech Paradise to Share His Knowledge About Liquid Fluoride Thorium Reactors
ByRod Adams July 24, 2009July 18, 2020

…on talking to a group of Google employees about LFTR. I have written about LFTR’s on Atomic Insights several times in the past; I even gave it a slightly different spelling – Liftr™ – so that people realize it is pronounced Lifter. As Kirk says much better than I do, liquid fluoride thorium reactors are an approach that makes energy resources for the future almost infinite. Go and invest an hour and twenty two minutes of your time to watch the tal…

Open letter to advocates of Generation IV reactors (IFR, LFTR, NGNP, PBHTR)

…t of us here and, in other venues in the pro-nuclear world. I’m a very big LFTR fan and I am active in LFTR circles but the success of of LFTR and any other Gen IV technology in my opinion is *wholly predicated on the success of Gen III*, specifically the current crop of AP1000s, CAP1000s, ABWRs, EPRs and APR1400s to name most of the first-of-a-kind-soon-to-be-built-or-already-being-approved Gen III reactors. The Chinese really understand this whi…

Open letter to Ralph Nader from Timothy Maloney – Atomic energy is much better than you think
ByGuest Author October 20, 2013July 11, 2020

…The actinides, mostly uranium and plutonium, are the proliferation worry. LFTR has almost no actinide waste. That is because, unlike a solid-fuel Generation 2 or 3 reactor, it does not have its fuel removed before it has all been consumed. LFTR fuel atoms are in liquid state so they can keep recirculating through the core tubes indefinitely until they are completely used up. The 2nd kind of waste, FPs such as cesium and iodine, can be further sub…

Kirk Sorensen’s Plan to Avert Climate Change – LFTR Presentation at Manchester Report

…dress climate change. (I have to admit a slight bit of professional jealousy here – I also entered into the contest, made the short list and then found out that I had not been selected as presenter. Darn.) Kirk has provided an excellent summary of his experience in a post titled LFTR and the Manchester Report. I encourage you to go and read that post, download his presentation, and share in the after glow of a job well done. Hat tip to Dave Bradis…

There are three Superfuels – uranium, thorium and plutonium

…aste that has longer half lives and requires sequestration). Every Thorium LFTR is a Uranium burning reactor (LFTR just burns U-233 instead of U-235). You will never get a LFTR to operate on Thorium alone. Cal Abel Joel’s comment on the spectrum is spot on. The transparencies above Pu-239 require a fast spectrum to fission in thermal specta they tend to build up. From a salt perspective you need something that is suitable fast spectrum fuel. The t…

The Atomic Show #185 – Is Thorium Superior to Uranium?

…risen too. It’s too easy to “dis” LWR when pointing out the superiority of LFTR. I think LFTR is superior in every way the LWR but unlike Kirk, I don’t believe it’s necessary to ‘put down’ LWR tech. I don’t think this is what Kirk “means’ to do but it comes off in his videos and interviews. I just think Kirk and others in the LFTR advocacy community have to be more consciousness about this. Rod, however, is overly ecumenical. The fact is that peop…

Identifying antinuclear slants in Richard Martin’s “Superfuel”
ByRod Adams June 26, 2012July 4, 2020

…vent of loss of coolant is not as safe as a molten salt based reactor like LFTR. LFTR achieves higher levels of safety with simplicity and out of the intrinsic qualities of chemically stable high temperature molten salts. There is literally no way that plumbing of molten salt reactors can explode like the high temperature steam plumbing of PWRs and BWRs, it is just not possible. This is also a significant safety difference that does matter to deci…
