Dr. Neff actually made his idea public in an Op-Ed article in The New York Times, entitled : A GRAND URANIUM BARGAIN.
The Op-Ed was published Oct. 24,1991. Read it here:
Some comments upthread mention our 'burden' of storing all the used fuel assemblies resulting from this. That isn't as much the result of adopting leftist nukes as fuel as it is from adopting leftist ideas about managing the valuable, NOT expensive 'used' fuel. Thorium reactors offer one way to profitably reuse that. I'm impressed by what I've read about them, but lack the background to exclude there being some 'catch' I'm overlooking. Thorium isn't the only method to reuse 'spent' fuel. France, the most nuclear dependent nation, uses another method, presumably with its own risks, and produces minimal 'waste' at the end of its fuel cycles. Thanks to Carter we're using the most 'wasteful' option.
