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.

A brief history of the extended transport correction for Legendre differential scattering cross-section expansions is presented in conjunction with calculations intended to investigate the validity of such expansions for the extremely forward-peaked scattering characteristic of that experienced by electrons. It is concluded from the results that approximate P11 cross sections obtained with the extended transport correction can yield excellent scalar flux solutions for electrons with energies between 10 keV and 1 MeV, even though P11 expansions are totally inadequate for representing the exact cross sections.
