NRC could improve decommissioning trust fund oversight, OIG reports
The Nuclear Regulatory Commission could do more to improve its oversight of decommissioning trust funds, according to an assessment by the NRC’s Office of Inspector General. In particular, the assessment, which was conducted by Crowe LLP on behalf of the OIG, identified four areas related to developing policies and procedures, workflows, and other support that would enhance NRC oversight of the trust funds.

The absolute ratio of fission densities due to thermal- and epicadmium-neutron fluxes has been measured by solid-state track detectors. A systematic deviation from this absolute ratio is observed when measuring gamma activities of fission products. From a careful analysis of the gamma spectra with a Ge(Li) detector, it was concluded that this systematic deviation is due to important changes in the mass distribution of fission products produced by epicadmium neutrons, with respect to the well-known mass distribution for thermal neutrons.
