The Carter Administration was right on this one--remember, he was a nuclear engineer. Looking at France's record with reprocessing their spent fuel should be instructive enough--I've excerpted below what I found out when you posted the article about Frances' nuclear waste program:
"Poking around to find out more about their reprocessing decisions and proliferation risks, I ran across this pretty scary report about France's role in proliferation of nukes around the world--seems that it helped Israel develop its reprocessing plant which has created its nuke stockpile, and even gave Saddam Hussein a reprocessing plant at Osirak, which Israel had to blow up to stop. France has not solved its radioactive waste problems with reprocessing--in fact it has made it worse. It's more expensive than standard waste storage, plus now they have a huge security risk by having accumulated 60 TONS of plutonium that could be made into nuclear weapons, and are still getting 8 tons/year more every year since 2005.
