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.

The transport equation is considered in toroidal geometry using an expansion of Ψ(r, Ω) in unnormalized spherical harmonics, i.e., with being associated Legendre polynomials. The variable r is the position vector and Ω the direction with axial and azimuthal angles θ and , respectively. Equations for ψlm(r) and γlm(r) are obtained and a method of solution that has worked in other geometries is outlined.
