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.

A procedure for measuring neutron cross sections and their ratios based on the multiplicity spectrometry of gamma quanta and neutrons emitted by excited nuclei is considered. Multiplicity spectrometers are described, and their functional characteristics are presented. Results of the radiative capture of fissile nuclei and highly precise alpha value measurements are analyzed in detail. Certain results of the absolute alpha value measurement at 235U resonances over the energy range up to 35 eV are given. The accuracy of the data obtained is ∼2%.
