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.

Neutron spectra in uranium depleted in the 235U isotope are analyzed with ENDF/B-III data, accounting for high-order anisotropic scattering. Two principal conclusions are made. First, changes made to inelastic scattering data relative to earlier ENDF/B files are not effective in reducing discrepancies between calculated and measured spectra. Second, changes made to unresolved capture data lead to significant improvement in the relation between calculation and experiment.
