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.

Cross sections of (n,p) and (n,np +pn + d) reactions have been measured at neutron energies near 14 MeV for 46,47,48,50Ti, 52,53Cr, 54,56,57,58 Fe, 59 Co, 50,60,61,62Ni, and 64,66,67,68Zn by means of the activation technique relative to the well-known 27Al(n,p)27Mg or 27Al (n,α) 24Na reaction cross sections. The samples are made of natural elements mixed with aluminum oxide (Al2O3), both in powder form. Gamma rays emitted by the residual radioactive nuclei are detected with a Ge(Li) detector in close contact with the sample. The data are compared with recently measured and calculated cross sections.
