Claims that new nuclear technologies are leading to “cleaner, safer and more efficient energy production” could only be justified with reference to concepts that exist only as designs on paper.
There’s nothing that can be said about ‘advanced’ reactor rhetoric that wasn’t
said by Admiral Hyman Rickover ‒ a pioneer of the US nuclear program ‒ all the way back in 1953:
“On the other hand, a practical reactor plant can be distinguished by the following characteristics: (1) It is being built now. (2) It is behind schedule. (3) It is requiring an immense amount of development on apparently trivial items. Corrosion, in particular, is a problem. (4) It is very expensive. (5) It takes a long time to build because of the engineering development problems. (6) It is large. (7) It is heavy. (8) It is complicated.”‘
