FINDING 2.1: Predefined frameworks have been developed and used to assess the proliferation resistance of partial or full nuclear fuel cycles. These methods provide a useful framework for comparing the intrinsic metrics or “attributes” of existing and potential future nuclear fuel cycles and for identifying where safeguards can be most effective in raising barriers to proliferation. However, these comparisons address a small subset of the wider range of issues faced by policy makers and the committee was able to determine that the frameworks have rarely been used to inform policy decisions. Additionally, there have been shortcomings in their execution.
