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.

The theory developed by Lindhard and co-workers for the partition of energy as an energetic ion slowing down in a solid has been applied to the calculation of neutron displacement cross sections for iron, chromium, nickel, stainless steel, and tantalum. ENDF/B data were used to incorporate anisotropic elastic and isotropic inelastic neutron scattering. A contribution from (n,γ) recoils has also been included. The results for stainless steel are presented in tabular form for convenience.
