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.

Fewer neutrons are produced from 11B(11B, n) than from 11B(p, n)11C for temperatures from 100 to 800 keV. For temperatures below 300 keV, 11B(d, n)12C produces more neutrons than either of these reactions if the normal isotopic mixture of hydrogen is used. Potentials generated by the double-folding method and tested against 7Li + 7Li data were used to generate 11B + 11B cross sections for energies where there were no measurements.
