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.

Recently, analytical formulas have been derived for the Feynman- and Rossi-Alpha measurements in accelerator-driven systems. In such systems, due to the multiplicity of the sources, the Feynman- and Rossi-Alpha formulas contain additional terms as compared with the traditional cases. A numerical evaluation of these formulas for systems with such sources is given. An assessment of the contribution of the terms that are novel as compared to the traditional formula is made. These include the terms arising from the source multiplicity, and the prompt-delayed and delayed-delayed correlations. Further, the consequences of averaging the delayed-neutron families are analyzed. Finally, a comparison is made, assuming traditional core material and one possible type of future accelerator-driven system.
