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 19F(n, p)19O and 19F(n, α)16N reactions from near threshold to 9 MeV. The 238U(n, f) reaction was used as a standard for determining neutron fluence, and a cyclic activation technique enabled measurements to be made on the short half-life activities of the reaction products. The results from this work are compared with corresponding data sets from the literature. These measurements support, qualitatively, the previously reported structure in the excitation functions for these reactions.
