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.

Four different epicadmium neutron flux spectra were produced by boron filter insertion in a beam port of the Cornell University 100-kW TRIGA reactor. The first spectrum was the unaltered (except for cadmium covers) fission slowing down spectrum; three hardened spectra were produced by the insertion of boron filters enriched in 10B. The shapes and amplitudes of the spectra were determined by the computer code SAND II to reproduce foil activation data obtained from a set of resonance and threshold detectors.
