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.

Cross sections have been measured for the 14N(n, p0) reaction from 0.5 to 7.0 MeV and for the (n, α0) and (n, α1) reactions from 1 to 15 MeV and from 4 to 15 MeV, respectively. The data were obtained using a gaseous scintillator containing nitrogen and xenon mixtures. A Linac was used as a pulsed white neutron source with a 29-m flight path. The results of the measurement are compared to the current evaluated file for nitrogen; agreement is good for neutron energies below 8 MeV, but the measurement is substantially higher than the evaluation for neutron energies near 10 MeV.
