The renewed interest in and activities related to nuclear power worldwide have raised concerns about proliferation, safety and security. The Obama administration is constructing policies that are at the same time consistent with and different from those of the Bush administration. For example, the administration is proceeding with efforts to win support for tighter rules on sensitive nuclear technologies in the Nuclear Suppliers Group (NSG) and to establish international nuclear fuel banks and other supply assurances. By contrast, the fate of the Global Nuclear Energy Partnership (GNEP), a centrepiece of the Bush administration’s nuclear approach, is still to be determined. However, concerns such as enhancing safeguards and security and efforts against nuclear terrorism will be integral to President Obama’s international nuclear energy policies.
