NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

Based on the experimental data of the total, nonelastic-scattering, and elastic-scattering cross sections and the elastic-scattering angular distribution of 209Bi, a set of optimal neutron optical potential parameters is obtained, and all cross sections of the neutron-induced reaction, angular distribution, energy spectra, gamma-ray production cross sections, and gamma-ray production energy spectra, especially the double-differential cross section for neutron, proton, deuteron, triton, and alpha-particle emission, are calculated and analyzed for n + 209Bi at incident neutron energies <20 MeV. Theoretical calculated data are compared with existing experimental data and other evaluated data from ENDF/B6 and JENDL-3.
