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.

Neutron capture up to 700 keV was measured for arsenic and bromine and for an enriched sample of 81Br. Individual resonance capture was parameterized in the first several kilo-electron-volts and average capture cross sections derived at the higher energies. Maxwellian average cross sections found for 79,81Br and 75As, respectively, were 741 ± 30, 244 ± 10, and 455 ± 18 mb for a temperature kT = 30 keV. Resonance capture integrals calculated for 79,81 Br, respectively, were 130 ± 5 and 46.6 ± 1.8 b.
