Great song, and not a bad way to introduce someone new to Thorium/MSR/LFTR.
When a LFTR (Liquid Fluoride Thorium Reactor) is used to extract energy from thorium, we could effectively “burn rocks” for energy.
Imagine a cube, perhaps roughly the size of a small car. In order to see the tiny amount of thorium that would be contained within the average dirt pile, we need to zoom in.
Thorium is only ~0.001% in an average pile of dirt, but it packs in so much energy, that – using LFTR, it contains the equivalent energy content of 30 times the amount of crude oil, compared to the size of the original dirt cube!

LFTR offers greater efficiency and safety over today’s operating reactors, and even proposed light water / boiling water reactors. LFTR also provides spare processes heat and valuable isotopes as a byproduct of normal operation, something today’s reactors can not, due to their low operating temperature.

We need a profound revolution in the way power is generated and delivered to our economies – cheap power, modular power, clean power. We need a revolution in power innovation, we need a new stream engine. – Simon Irish
Mark (writer for Smartplanet) contrasts thorium molten salt reactors with Bill Gates’ TerraPower, General Atomics, QPower (pebble bed) and other companies pursuing modular reactors. China itself could build as many as 100 reactors by 2030, and is actively pursuing a wide range of nuclear technologies (100 companies).
Richard was one of the first energy experts to promote the development of thorium (in Wired Magazine). SuperFuel explains how we can wean ourselves off our fossil-fuel addiction, deliver a safe energy source for a millennia, and avert the risk of catastrophic climate change.

You wouldn’t use a 20 year old cellphone, so why are we using 20+ year old nuclear technology? The curious reason we are, is because it works, but we could be doing so much better.
Here is the short overview on LFTR and Thorium (the fuel of the future):
– Element 90, found as Thorium 232 in nature, is 4 times more common than Uranium and about 200-400x more common than U-235, the fuel we burn in Light Water Reactors (LWRs) in the US and much of the world. That’s just the start…
– Thorium is naturally radioactive like uranium, and has a half-life equal to the age of the universe (about 15 billion years) so it will be with us for a long time
– It is found in large quantities in “Rare Earth” mines, which are rare in the US because they dig up Thorium. Thorium is (weakly) radioactive, and US law requires it be treated as a radioactive waste and buried. Too much Thorium in a rare earth mine makes it unprofitable, but it is these rare earth mines that bring up the high technology metals we need in society today, such as Neodymium for magnets (think generators and motors).
– A LWR (Light Water Reactor) in the US burns about 0.5%-5% of the fuel put in it, the remaining is disposed of as unburned fuel as part of the radioactive waste. A LFTR on the other hand, running from Thorium could burn 100% of the fuel
– Because it can all be consumed, if you held a marble a little over an inch across (~3 cm) made of Thorium, it could power your entire (western world) needs for your entire life. (more: http://www.youtube.com/watch?v=qbGZ_Y-xkPM)
– The “waste” products are far less than that of the Light Water Reactor technology used today. Also, the amount of mining is far less – and a natural result of a rare earth mine (see above). (more: http://energyfromthorium.com/2007/01/09/uranium-vs-thorium-mining-processing-waste-generation/ and http://en.wikipedia.org/wiki/Liquid_fluoride_thorium_reactor#Economy_and_efficiency)
– The byproducts of a LFTR are radioactive, but contain few “transuranic” elements – which would be radioactive for a very long time. Instead, much of the “waste” could be recycled into useful products after a month or a few years of cooling off, and by about 100 years, much of the radioactivity is gone.
– There is less risk of proliferation with LFTR (Thorium) fuel, since Thorium doesn’t fission in of itself, and stolen active LFTR fuel would contain U232 (a natural byproduct of the LFTR process, not required to be added). U232 is very radioactive and would damage electronics and irradiate the people stealing it, and make any stolen material easy to find.
LFTR – Liquid Fueled Thorium Reactor (A molten-salt reactor using thorium)
– A LFTR is a different kind of reactor. It was invented during the 1950s and 1960s in Oak Ridge Labs, but was quickly abandoned since the nuclear reactions were found to be not good for bomb-making. (more: http://youtu.be/bbyr7jZOllI?t=1m6s)
– Since the focus was on bombs and Uranium originally, the infrastructure of LWRs (light water reactors) quickly grew and stabilized, ignoring Thorium technologies such as LFTR (more: http://youtu.be/bbyr7jZOllI?t=12m1s – hear the Nixon tape – very damning evidence, and a real shame).
– This kind of reactor can’t “melt down” as it is already liquid. It runs in the 700°C [1300 °F] range giving far superior thermodynamic efficiency. High pressure is nowhere near the core, since a hot salt loop transfers the heat to the generators.
– The reactor is designed with a “salt plug” in its base, cooled by a fan. If power is ever lost, the system fan would shut down (due to lost power), and the plug melts, draining the fuel into a storage container where fission stops. The fuel would also cool and solidify. If there were ever a breach in the reactor, material would drain into the same tank. Even if the tank broke, the fuel would simply solidify on the floor. Safety can be done completely passively, no worries about hoping systems will be online when needed. (more: http://youtu.be/enjc4arwH7U?t=3m30s)
– The reaction has a natural “negative feedback”, which means that if demand for power grows, the reactor will run faster, but if it falls, it will reduce its output. It also will run slower as it gets too hot, so more heat does not make the reaction go out of control, it actually slows the reaction (due to expansion making fission less likely).
– The fuel is cheap (see Thorium above), and since there is no high pressure, huge thick walls and buildings are not necessary. This lowers the space and cost requirements of a building.
– Any nuclear fuel generates Xenon gas while in a reactor. This gas slows reactions and in the case of LWRs and other solid fueled reactors that we use today, it cracks and damages the fuel pellets. Since LFTRs are liquid, it simply bubbles out of solution. It can also be collected, and in a few months is no longer radioactive and can be sold. This is also one reason the fuel in our current LWRs is only 0.5%-5% consumed, because if it were to be left in longer, the expansion from this would damage the fuel tubes inside of the reactor.
– LFTRs can make isotopes of materials we desperately need. Mo-99 is needed by hospitals for radiation treatments, Pu238 is needed by NASA for space missions to the outer reaches of the solar system, and Bi213 for new targeted (Leukemia and Pancreas) cancer treatments. (more: http://www.youtube.com/watch?v=2at8C8YrX80)
– LFTRs can also burn radioactive “waste” we are currently storing, made from the LWR units of today. We could actually reduce our radioactive waste using LFTRs and other Molten-Salt Reactors (MSRs) (more: https://www.youtube.com/watch?v=i1fqB6p9pgM).
– China is already working on LFTR technology and stockpiling Thorium. India is working on Thorium for solid fueled reactors, but will probably move to LFTR as a natural part of that research. (more: http://en.wikipedia.org/wiki/Liquid_fluoride_thorium_reactor#Recent_developments)
Did you know?
– A typical coal burning plant emits far more radioactivity into the air than any nuclear plant. Nuclear plants keep their fuels inside the building, but the smoke from coal contains all manner of poisonous materials (mercury, cadmium, etc) and several naturally radioactive ones such as Uranium and Thorium. These materials are fairly safe as rocks, but as a breathable dust, not so much.
– Nuclear power is over 1,000,000 times more energy dense than burning fossil fuels. The comparison is nuclear energy to that of a carbon-hydrogen bond. (more: https://www.youtube.com/watch?v=NG2jN–D2Es – See a visit to Arizona’s Palo Verde Energy Education Center outdoor exhibits)
– US current needs for energy burn a rail car of coal about every 1-3 seconds. That’s about 100 tons per rail car.
– There have been far more deaths from coal mining than all nuclear power accidents combined. (more: https://www.youtube.com/watch?v=4E2GTg7W7Rc – graphs at 2m:40s)
