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.

Total cross sections for the emission of protons and alpha particles have been measured for 9.4- and 11-MeV neutrons incident on a 4.11 mg/cm2 thick Type 316 stainless steel target. A newly developed charged-particle time-of-flight spectrometer was used to obtain (n, xp) and (n, xα) cross-section data. The measured gas-production cross sections have been compared with the values predicted on the basis of measured or calculated cross sections of the constituent materials.
