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.

The effect of low-energy neutrons on activation cross-section measurements was analyzed carefully and proved by the measured neutron spectra of T(d,n)4He and D(d,n)3He reactions. The 58Ni(n,p)58m+gCo and 64Zn(n,p)64Cu reactions were used to confirm this analysis, and their cross sections were measured accurately. In addition, their evaluated excitation functions are given.
