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.

Capture cross sections and gamma-ray spectra for the neutron-induced reactions with mTa and 197Au have been calculated using the level density parameters derived from a new low-lying level fitting method in which the constant temperature partial level density formula and the spin-selected level cumulation were used. The gamma-ray profile functions, of the Brink-Axel type with an anomalous bump, were employed for both nuclei. The capture cross sections, spectra, and gamma-ray strength functions obtained in the present calculation agree well with the experimental ones.
