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.

Differential cross sections for neutrons scattered elastically from 6Li and 7Li have been measured at 14 incident neutron energies between 4 and 7.5 MeV. For 7Li, neutrons inelastically scattered from the 0.478 MeV-level were not resolved from the elastic group and have been included with the elastic group in calculating the cross sections. The present 6Li data are in good agreement with the ENDF/B-IV evaluation, while the present 7Li(n,n0 + n1) data are generally larger than the corresponding ENDF/B-IV evaluation particularly at forward angles.
