> That list includes the US, which hasn't had commercial reprocessing in many decades. But it also includes many countries that reprocess currently. The US has not reprocessed fuel in many decades, and never on any significant scale, because the Carter Administration outlawed it based on mistaken concerns about proliferation, and it's been a political pariah ever since. It has nothing to do with any rational technical assessment.

Pakistan and India do it for their nuclear weapons programs. You don't want to be making that argument. The UK, France, Japan, and Italy don't reprocess anymore (I'm not sure Italy ever did on any substantial scale). Carter stopped reprocessing by executive order, but Reagan quickly reversed that order. No reprocessing then occurred, because reprocessing made no economic sense. It turned out Carter's order isn't what killed reprocessing in the US; cold hard economics did. It did provide a convenient excuse for those who wish to ignore that reality.

  > Carter's order isn't what killed reprocessing in the US; cold hard economics did. No, "cold, hard economics" would say, if you are correct that it's not even cost effective to do any reprocessing now, that the spent fuel should be stored for 100 years or so and then reprocessed, when it's economically cost effective. But US policy has been that spent fuel has to be stored in a facility that's good for 100,000 years. That makes no sense if the waste is going to be reprocessed 100 years from now. It makes sense only as part of a political scheme to kill nuclear power altogether. Which is exactly what it was, even if on paper reprocessing was "allowed" after the Reagan administration.

    You do raise a good question: why was there this idea that burying waste now was a good idea? I can think of two reasons: First, it may have been thought that opposition to nuclear energy is due to waste, and that burying it would remove the opposition. I consider this ill-founded, both because those predisposed to oppose nuclear use waste only as one of many arguments, and because the actual objective argument (economics) as nothing to do with waste. Second, it may have been thought in the height of the Cold War that spent fuel at the surface would be a tempting target for ground burst H-bombs, where it would then contribute to long term fallout (each 1 GW(e)-year of spent fuel has about the same long lived fission products as a 20 MT bomb.) This is not an argument the government would have been pushing publicly, of course.

      > why was there this idea that burying waste now was a good idea? I've already answered that: nobody actually thought it was a good idea. It was imposed as a policy because the actual (though of course not publicly admitted) purpose of the policy was to kill nuclear power by imposing unreasonable requirements on it. (It's possible, I suppose, that the Cold War rationale you give played a role, but I don't think it's very likely; that objective could have been met without requiring anything like 100,000 year storage.)
