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 temperature distribution in a cylindrical fuel rod has been calculated on the assumption that the flux distribution is expressible in the form of a series of Bessel functions, whether or not it actually obeys the simple diffusion equation. Variable thermal conductivity has been taken into account and a generalization of the classical solution has been obtained. A simplified design formula for a solid rod has been derived.
