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.

We consider all 25 projectile-target combinations of the particles p, d, t, 3He, and α. We obtained nuclear plus interference elastic cross sections for such interactions by subtracting Coulomb contributions from experimental data. We present evaluated graphs of the following resulting quantities, integrated over center-of-mass scattering cosine: reaction rate, average fractional energy loss per collision, average fractional energy loss per unit path length, and average laboratory scattering cosine. This information can be used to correct energy loss rates due to Coulomb scattering, or in more exact transport calculations that account for large-angle nuclear scattering.
