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 measurements were made on a sample of fission product palladium at the Oak Ridge Electron Linear Accelerator time-of-flight facility. One hundred thirty resonance peaks were parameterized up to 3.5 keV and the average cross section from 3 to 600 keV was derived. The data exceed the ENDF/B-Vevaluation by ∼25% in the 3- to 300-keV range but drop steeply below it at higher energies where neutron inelastic-scattering competition becomes important. The Maxwellian average cross section for kT = 30 keV is calculated as 1.34 ± 0.06 b, and the dilute resonance capture integral as 108.1 ± 4.3 b.
