Ok, I looked briefly at the thorium thing. Sounds like a nice reactor technology, already demonstrated. It seems the fuel cycle is actually U-233 based, and that is made from Thorium by neuteration. Overall it seems a superior fuel cycle re waste and safety. BUT, it inherently does require fuel processing which in past experiences has had both cost and maintenance and safety issues. That salt will still be quite radioactive, hard to handle for reprocessing, and producing traces of product species that could lead to corrosion. Would I support a $200M project to explore thorium cycle in the US? If the nuclear engineers said it looked feasible, I would. Is it clear that it is easy as pie and the solution to all our problems? Not yet.
