Have the efforts to promote the peaceful spread of nuclear technology been successful? At first glance, the answer seems to be yes: more than twenty countries have active nuclear reactors without having nuclear weapons programs. But perhaps this only underscores the fact that the proliferation of nuclear weapons operates by altogether different means. As in the cases of North Korea of Israel, it is clear that the technology, expertise, and fissile material necessary to create weapons can (and does) circulate independently of the regulated systems of nuclear power production. While nuclear power presents its own safety and environmental problems, restricting nuclear power may do quite little to address problems of nuclear weapons production.


I've also made maps of nuclear explosions and uranium production.
