I saw a lot about the thorium cycle. Apparently the Indians have worked a lot on it. Australia, India and the US have the largest reserves.
Thorium is unnecessary we have mined enough uranium for.thousands of years of human use as long as you one reprocessed spent fuel into MOX and then burn said MOX in a high conversion ratio reactor. The choices of HC ratio reactor is large you can use sodium fast reactors with a CR of 1.4 or you can use BWR water reactors with a tight lattice and a moderator to fuel ratio of less than 0.5 those have CR=1.1 or greater same for a PWR reactor with a MF ratio of 0.3 or less. You can also use supercritical water mixed spectrum reactor with a CR or 1.2+ or supercritical CO2 with a CR of 1.4+ any of those create more fuel the form of PU239 than they burn in the fuel cycle. You MUST reprocess the fuel using fuel once and throwing it away is a crime against humanity. The ONLY reason Carter and the anti nuke zealots banned reprocessing is to cripple the nuclear industry and soon it to designed failure. There is a reason the Russians,Chinese,French, Japanese and Koreans all reprocess fuels they understand science that spent fuel is still 96% fuel. In a once through cycle you get 1% of the energy out of uranium the rest is thrown away with reprocessing you get access to the other 99% just the spent fuel in the USA alone has TRILLIONS of barrel equivalent energy this says nothing of the 600,000 tons of depleted uranium from the enrichment program that contains TRILLIONS more enough to support Western standard of.living level energy consumption for tens of thousands of years. It was 100% designed to cripple the nuclear industry in America by banning reprocessing. Carter should have been tried as a traitor and with crimes against humanity for that one executive order. F him when he finally gets to room temp I hope I live long enough to piss on his grave.
