vue - Thorium: An energy solution - THORIUM REMIX 2011
http://patreon.com/thorium Thorium is plentiful & can be used to generate energy without creating 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.

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 Additional nuclear fuel can be added or withdrawn from the salt solution during normal operation.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. "Fluid Fuel Reactors", James A. Lane, U.S. Atomic Energy Commission, 1958. http://moltensalt.org/references/static/downloads/pdf/

no chinese?

I'm super young and want to make working on Lftrs as a full time job (I know they aren't 100% operational yet, but eventually they will right?) How would I go about doing this? What degree should I aim for, Nuclear Physicist or nuclear engineer? what University should I aim for? I took a lot of advanced science classes in high school, so I'm familiar with the sciences. What general course of action should I take to help this get off the ground? Please answer. I just really want to be a part of this.

I'm sorry but Elizabeth May is a dumbass.

Google translate of ieder andere vertaalmachine welke was gebruiken is niet de goed manier voor ondertitel in Nederlands. Ik wil blij zijn te verstaan de originele gesprek; maar storend toch wel die vertaling in de tekst in de beeldenfilm.

I wrote to a US senator about this and I got the usual canned reply back thanking me for my interest in the senator blah, blah. I don't think they know what your talking about or care. I wish I could believe we had the same energy and clarity of purpose we had back in the 60s to do this but I don't see it. I do see that we have made some kind of deal in 2015 where our researchers will be helping China build their reactors and sharing the information gained. I guess it is better someone do it even if it is not us but sometimes you just have to wonder where did we start going so wrong. To have the green party and other environmental groups who want desperately to halt climate change leading the opposition just makes it seem like a betrayal.

Awesome vid! I can't stand when some people say "new-cue-lar" like some kind of republican though.
-
An amazing video!!! I will be hounding my state reps and EVERYONE about this.

Hello. I am a psychologist here in brazil, and one of the most valuables teachings of our job is that every point of view is important; the given wrong ones are so not only for a matter of fact, but mostly by contingency -social, financial, you name it. This i would really like to thank you for sharing this vídeo. Im personally a nuclear power entusiastas and yeah, this vid. was quite refreshing as a counterpoint of what weve grown weary to see about radiation.
Always good to see something new -
I'm watching this documentary for the 5th time, it's so fascinating! I find out new facts every time! Thank you Gordon and Kirk for making these!

Why is the water pressure measured in, or expressed as such and such atmospheres?
Instead of 150 Atmospheres, why not say 2100 PSI? -
All of this sounds amazing but I have a looming sense of dread that tells me this is too good to be true.
Can a nuclear physicist please tell me that I don't have to worry that this will be the next placebo solution to our energy problems? -
I would like to organize a project with you to start in nyc with RhombuZoid INC, think tank.

Hey! San Onofre!! I've been inside the steam generator - I've worked over the massive the turbines, etc.
I was thunderstruck (in awe of) Unit One - Until I worked at Units 2 and 3. EVERYTHING in them is massive.
While in construction phase we had a lot of prank fun. - Once they started putting in the heavy water, fuel rods, etc, we could get fired immediately, and escorted to our cars with armed security for any reason they thought a threat. (All joking stopped.)
My security clearance was as high as the President's.
An incredible time in my life. -
we just need smart people to take the microphone so that the information being disseminated to the public, is the right information. We can't afford fear mongers and worse, people and newsies who are being told what to say on televised news by people with dangerously low levels of knowledge.

People! Go watch the 2016 version of this with the practical applications of LFTR: Space exploration and colonization. This would be right up Elon Musks alley, to get humanity first on the Moon permanently and later Mars.

Fantastic loved your
Video. Kirk I loved they way you put things in such simple terms that
many people can understand (including me). I've already read about Thorium
reactors about a year ago (or more) and was already thinking the same
thing when I first saw how much better is sounded than most other
energy solutions we now look at. I am also happy to see that there
is now continued research at Cambridge University as of October 2014
that shows that we do seem to be moving in the right direction as
seen
http://www.cam.ac.uk/research/news/cambridge-team-explore-power-of-thorium-for-improved-nuclear-design.
I was surprised that it wasn't a university in the USA, but any
research is good thing. But as Kirk pointed out sounds like China is
already pumping more money into it and will probably be the winners
at getting to a solution to making a profitable return on it long
before USA or the UK. I assume the USA government and corporations
are just too short sited to see the benefits to mankind and the world
rather than just looking for short term profits gains with the
infrastructure they already have. The USA should have at least a 1$
billion program to be used to develop and build a working scalable
power plant that I imagine with funding could be done within 8 years
or less. I can imagine from what they learn, will probably pay for
itself within 10 years. Is that such a big long term investment to
make to save the planet from global warming and wars over oil? -
Build an LFTR reactor to bring energy to the oil sands for oil extraction at 1:04:15 ? Are you kidding? I could not believe my ears. LFTR is to nuclear power as the computer mouse is to computers. When the mouse was proposed it was mostly ignored and scoffed. Today, it is an obvious, essential technology tool choice. Great presentation here. Why aren't we building more of these in favor of the water reactors? The reason can't be cost because all nuclear power plants are expensive. Given that nuclear is expensive, initially, it seems the lowest health, safety, and environmental risk impact would be LFTR due to low pressure, no need for triple+ redundant backup systems, the reaction itself is positive stable, the efficiency is 90%+ and not less than 1% like the other reactor types. Then there's the ingenious "freeze plug" concept which drains the liquid salt, by gravity, which inhibits the reaction if, for any reason, the power to the electric circulation pumps is disrupted. The availability of fuel - Thorium - is on par with Lead whereas Uranium is on par with Platinum. The cost of mining for Uranium, alone, would scare venture capital, based on it's difficulty to find. The primary concern should 100% be safety and not whether or not Plutonium can be made. There are too many positives for this LFTR method of nuclear power to be ignored: no carbon emissions, high efficiency, built-in safety (not engineered safety), abundant and available fuel source, relative simplicity and elegance of design, no giant cooling towers because the heat energy extracted when the water cycle steam expands through the turbines of the electric generator (I assume that a condenser similar to what coal plants use would be needed in that case), and there is even an isotope useful for fighting cancer that results from this reaction.
