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.

Within the framework of the Hauser-Feshbach-Moldauer formalism for calculating fast-neutron cross sections, resonance interference effects are contained in the parameter Q. This parameter is shown to be a function of the corresponding transmission coefficients. From a parametric analysis of Q and of the channel coefficients, it is concluded that resonance interference has a negligible effect on the calculated cross sections.
