Crust asks:

We're likely to see a lot more nuclear energy globally because of global warming and energy prices. What is the right way to reduce the proliferation risk?



This is easy (to answer, not to actually do) you need to multinationalize the nuclear fuel cycle:



You can also see "Multilateralism as a Dual-Use Technique: Encouraging Nuclear Energy and Avoiding Proliferation" by John Thomson and Geoffrey Forden for the Stanley Foundation which I've recommended in the past. I note that proliferation risk is one of several good reasons to hope that we don't respond to global warming with huge new investments in civilian nuclear power, but as at least some expansion of nuclear power seems inevitable it's important that we get this right from a security standpoint.
