Description:
http://thoriumremix.com Thorium is readily available & can be turned into energy without generating transuranic wastes. Thorium's capacity as nuclear fuel was discovered during WW II, but ignored because it was unsuitable for making bombs. A liquid-fluoride thorium reactor (LFTR) is the optimal approach for harvesting energy from Thorium, and has the potential to solve today's energy/climate crisis. LFTR is a type of Thorium Molten Salt Reactor (Th-MSR). This video summarizes over 6 hours worth of thorium talks given by Kirk Sorensen and other thorium technologists.THORIUM REMIX 2011 starts with a 5 minute TL;WL summary, to hold you over until you find your Ritalin. YouTube Closed Captioning is available in English, and many other languages.To learn more about the Liquid Fluoride Thorium Reactor visit: http://energyfromthorium.com/See http://THORIUMREMIX.com/ for full list of multimedia source material.Key YouTube video components:Kirk Sorensen @ TEDxYYC http://www.youtube.com/watch?v=N2vzotsvvkwKirk Sorensen @ Protospace - http://www.youtube.com/watch?v=YVSmf_qmkbgKirk Sorensen @ MRU - http://www.youtube.com/watch?v=D3rL08J7fDAKirk Sorensen @ TEAC3 - http://www.youtube.com/watch?v=6-uxvSVIGtUKirk Sorensen @ Dr. Kiki Science Hour #84 - http://www.youtube.com/watch?v=vEpnpyd-jbwAfter Fukushima: The Fear Factor - http://www.youtube.com/watch?v=OVQ0NvEcyqwRobert Hargraves @ TEAC3 - http://www.youtube.com/watch?v=BOoBTufkEogAlexander Cannara @ TEAC3 - http://www.youtube.com/watch?v=aUVq81kBKykJames Kennedy @ TEAC3 - http://www.youtube.com/watch?v=mrDeB86YpV4Q: What is thorium and what makes it special?A: Thorium is a naturally-occuring mineral that holds large amounts of releasable nuclear energy, similar to uranium. This nuclear energy can be released in a special nuclear reactor designed to use thorium. Thorium is special because it is easier to extract this energy completely than uranium due to some of the chemical and nuclear properties of thorium.Q: What is a liquid-fluoride reactor?A: A liquid-fluoride nuclear reactor is different than conventional nuclear reactors that use solid fuel elements. A liquid-fluoride reactor uses a solution of several fluoride salts, typically lithium fluoride, beryllium fluoride, and uranium tetrafluoride, as its basic nuclear fuel. The fluoride salts have a number of advantages over solid fuels. They are impervious to radiation damage, they can be chemically processed in the form that they are in, and they have a high capacity to hold thermal energy (heat). Additional nuclear fuel can be added or withdrawn from the salt solution during normal operation.Q: Are the salts safe?A: Very safe. Unlike other coolants considered for high-performance reactors (like liquid sodium) the salts will not react dangerously with air or water. This is because they are already in their most stable chemical form. Their properties do not change even under intense radiation, unlike all solid forms of nuclear fuel.Q: What is nuclear waste and how does a liquid-fluoride reactor address this issue?A: So-called "nuclear waste" or spent-nuclear fuel is produced in conventional (solid-core) nuclear reactors because they are unable to extract all of the nuclear energy from their fuel before they have to shutdown. LFTR addresses this issue by using a form of nuclear fuel (liquid-fluoride salts of thorium) that allow complete extraction of nuclear energy from the fuel.

May 11, 2012 - Just a heads up, some might bring up the formation of cataclysmically corrosive HF which is understandably a problem but there are solutions/materials that can combat it, and ensuring that none of the fuel mix comes in contact with water is key.

May 20, 2012 - Question: at 3:40, he mentions burning U-235 for power. Actually the fuel (MOX) is only 7% U-235/Pu, the rest is U-238, is that not right? Thorium fuel needs to have this U-235/Pu in order to convert the thorium to U-234 at startup, right? So is the scarcity of U-235 a red herring?Just trying to get this density of facts straight in my mind. Thanks for comments.

May 21, 2012 - According to the diagram on pagge 12 of thoriumenergyalliance(.)com/downloads/TEAC3%20presentations/TEAC3_Sorensen_Kirk.pdf , the fluorine comes out as fluorides of various fission product isotopes. If it is advantageous (for chemical engineering reasons) to leave them that way, then that is the way they will be stored; otherwise they'll be reduced and the fluorine will become NaF or KF or some such, or perhaps ultimately recycled to produce more LiF, BeF2 or ThF.
puncheex Says:
May 21, 2012 - As he said, it's not used because its chemistry and nuclear physics haven't been plumbed to the same depth, so there are more unknowns.
puncheex Says:
May 21, 2012 - Look up "hormesis" and read into it. The linear model was developed in Japan after WWII, and there were a dearth of people with low exposure examined, so the linear model was used as the simplest available. Chernobyl has created a lot of interest in hormesis, and makes sense to a lot of the medical people who have studied that accident.
puncheex Says:
May 21, 2012 - You can't question hormesis without making an implicit assumption of linear threshold, aka policy status quo.
puncheex Says:
May 21, 2012 - Sorry - reality is the judge. If you think Kirk is wrong, then it is your privilege to bring your evidence that that is so to this and any other forum you care to. If you can't, then the next best thing is to trust someone else who does. If there are none such, then your "sane society" hasn't got a leg to stand on.

May 21, 2012 - Sure it would, if we lived in a purely capitalist society, but we live in a republic, with governmental regulations around the edges, so perhaps such would not be prudent (consumer relations) and/or legal. It might even happen that one would be compelled to pay the true price of coal (including environmental remediation) for its use.
puncheex Says:
May 21, 2012 - (I think delphi was referring to the slide in which it was demonstrated that LFTR could do more than "just electricity", and that the electricity could be turned to creating fuels for transportation. Feedstocks for those processes might well include raw carbon (coal) as opposed to CO2 from the air.)
puncheex Says:
May 21, 2012 - You asked why "how did this guy just say with a straight face that radiation is good for you because it damages your cells". That question assumes you that you consider his stance outlandish with respect to ... something. I would recognize that something as the linear threshold model, it being the only other game in town. Free-form comparisons are not very logical.
puncheex Says:
May 21, 2012 - This is a pretty common latter-day feeling, but it doesn't really make sense. After all, we elect the government, and its employees are ... us. If they do silly things, it's our fault. They delivered mail long before anyone saw money in it; they fought the Nazis in Europe. They fund NASA, the US Weather Bureau, oceanography, and your local agricultural extension service. You just want everything your way.
puncheex Says:
May 21, 2012 - Most of the problems with industrial level uses of fluorides were solved by the Manhattan Project, 60 years ago.
puncheex Says:
May 21, 2012 - The problem with salt water in the FD reactors is that it corrodes a vessel which is designed to handle only pure water. The LFTR vessel is designed to handle the salts involved, and probably a range of possibilities brought on by accident as well. The two cases simply aren't comparable in the way that he is trying to do it; they are different "by design".

dbirchle Says:
May 26, 2012 - Do you not get the concept? The policy currently in place is that there is a linear relationship between amount of radiation and negative health effects. This is an idea sprouted from high-dose radiation studies, but all data from low-dose studies contradict that idea. It seems there is a threshold after which negative health effects take place and before which there are actual benefits, which is good news for a lot of reasons.
dbirchle Says:
May 26, 2012 - Do you not understand the concept of cost? Cost represents that which an individual or group will be giving up by making or purchasing, not just a number of dollars. High cost + low utility (includes efficiency) = bad idea. High cost + high utility + low side effects = very good idea.
dbirchle Says:
May 26, 2012 - I'm not convinced it is necessarily the best way to go, and his analogies comparing fission to fusion don't really apply to the small companies building small fusion reactors. One cannot lump all fusion together just as one cannot lump all fission together. Here's hoping, though, that FliBe energy is well-funded and many LFTRs are built and used in the US.
