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.

Consistent evaluation of the 232Th capture cross section is performed in the energy range from 4 keV to 5 MeV. The Hauser-Feshbach-Moldauer theory and coupled channel optical model are employed. Total, differential scattering, fission, and inelastic scattering data are consistently reproduced as a major constraint for the capture cross-section estimate. Average resonance parameters are obtained, which are consistent with the capture cross-section database.
