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 neutron cross sections of 10B for elastic scattering have been measured for ∼30 incident neutron energies between 4 and 8 Me V. Neutrons inelastically scattered from the 0.717-MeV level were completely resolved from the elastic group except at the most forward angles at energies above 7.5 MeV. Generally, the differential cross sections are slowly varying with energy, indicating little resonance structure in this region. These data are consistent with earlier lower energy measurements done at Edwards Accelerator Laboratory and provide detailed data in a region where only sparse data were previously available to evaluators and designers in the nuclear energy field.
