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.

All cross sections, energy spectra, and double-differential cross sections of six outgoing particles (neutron, proton, deuteron, triton, 3He, and alpha particle) for the p+90Zr reaction are consistently calculated and analyzed at incident proton energies below 200 MeV by using nuclear theoretical models. The optical model; distorted wave Born approximation theory; the intranuclear cascade model; the exciton model; Hauser-Feshbach theory and the evaporation model; and, especially, the improved Iwamoto-Harada model of light composite particle (deuteron, triton, 3He, and alpha-particle) emission have been included in the calculation, which is in good agreement with the experimental data.
