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 penetration in water and through iron-water shields of practical interest obtained from P3 multigroup calculations employing P0-P3 scattering components has been reasonably reproduced by P3 11-group (10 nonthermal) calculations limited to P0 and P1 scattering components to which an extended transport approximation incorporating empirically determined cross-section adjustment factors is applied.
