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 previous hot spot statistical analysis was extended to a more complete assessment of the reliability of a reactor core against over-temperatures. A simple procedure allows the designer to evaluate the expected number of hot spots and the average number of pins and subassemblies in which they occur. The influence of the different types of uncertainties on these quantities is examined.
