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 general multidirectional modal representation for the angular density of the one-speed neutron transport equation is discussed. The properties of orthogonality and recurrence are presented together with expressions for several neutranic parameters. The system of equations for the spatial moments are established and certain features described. It is shown that some known solution formulations are special cases of this more general representation.
