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 63Cu(n,α)60Co cross section has been measured by activation relative to the well-known 27Al(n,α)24Na cross section. The 60Co and 24Na activities induced were measured with a 5- × 5-in. NaI(Tl) well-type scintillation detector. The average neutron energy was 14.80 ± 0.02 MeV, with an energy spread of ∼0.3 MeV. As the result, a value of 40.7 mb was obtained for the cross section with an accuracy of approximately ±2.5% (effective standard deviation) on a 1σ confidence level.
