Executive Summary

We will detect and characterize stable isotope signatures in material created during the nuclear fuel-cycle process to provide new information about production processes beyond that determined through environmental sampling. Our research will address the threat of the spread of nuclear materials by developing new signatures of nuclear proliferation and improving our capability to assess activities at nuclear facilities.
