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.

High resolution measurements of the total neutron cross section from 200 eV to ∼50 keV in natural copper have been performed using time-of-flight techniques. From the R-matrix analysis of the data, values of E0, Γn, Jπ of resonances, strength functions, and average level spacings are obtained. For in units of eV−1/2 were obtained. Similarly, the average level spacings are determined for 63Cu〈D〉 J = 1 = (2.38 ± 0.38) keV, 〈D〉J = 2 = (3.57 ± 0.70) keV and for 65Cu〈D〉J = 1 = (3.85 ± 0.88) keV and 〈D〉J = 2 = (5.0 ± 1.2) keV.
