Anyone interested in comparative costs between thorium-fuelled
and uranium-fuelled nuclear reactors, and the relative risks?

Yep, particularly for the second world where its not a great
idea for them to be able to produce bombs etc and where
its very desirable to have fail safe systems instead of systems
that need very high quality designs.

For the avoidance of any misunderstanding, I am making no comment
at this stage either as endorsement or criticism of that web site.
