Sorry, Greg, I am not convinced.
I have reviewed the reference you provided, and have learned a lot. Mainly, I have learned that nuclear power plant design has come a long way from the early 70's, when I researched LMFBR's (liquid metal fast breeder reactors) for Senator John Tower R-TX.
Depending on design, the wastes may be mitigated by a factor of 100, but not eliminated. The accident potential remains the same as light water reactors. The sodium cooled designs introduce a new risk factor, if the core cooling sodium should come into contact with the water used for steam, the resulting explosion will obliterate the core. Perhaps in a few more decades, the concept may mature to a safe alternative.
Regarding your second argument, it is very lame ..... one of your examples picked Solindra as a winner, and another cannot find his way off a podium. Not to worry, it is the Congress (both houses) that pick the winners and losers, and their win/loss record would get them fired if they managed a sports team.
Slick
