A lot of the problems with nuclear technology have to do with nuclear weapons proliferation. Some of the better energy-production technology has high risk of proliferation (e.g., produces plutonium as a byproduct).

The paragraph swapping was excellent. I'm serious. The danger (for me, who would like to learn the language) of keeping the paragraphs on their respective sides, is that I will tend to read one and then go to the other for reference. I imagine a lot of readers would go for their prefered language and perhaps glance across occasionally. But flipping randomly (and I especially liked that it didn't happen at the beginning. Get the flow going first, and then whang!, hey! I'm reading spanish, no english, no ingles, no espanol, hey, I'm reading two languages! That was the effect on me, anyway.)
Plus there was a relevant news story attached. Don't fight forces, use them R. Buckminster Fuller.
So I don't disagree on that, I am saying that the reason breeder reactors are not more widely used is that <gasp> they can be used to proliferate. Nothing is 'mere'. — Richard P. Feynman
The real reason breeders aren't widespread is cheap uranium.
