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.

Energy-averaged total neutron cross sections of elemental vanadium were measured from ∼1.0 to 5.5 MeV. Differential elastic and inelastic neutron scattering cross sections were measured from 1.8 to 4.0 MeV. Neutrons corresponding to the excitation of states in vanadium at 321 ± 10, 938 ± 15, 1603 ± 19, 1811 ± 21, 2409 ± 27, ∼2500, 2706 ± 30, and 2773 ± 30 keV were observed. These experimental results were used to deduce an energy-averaged nuclear model suitable for extrapolating the measured values and calculating unmeasured cross sections for applied use.
