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.

Sodium boiling situations in a fast-reactor fuel element can be calculated with the BLOW-2 code from their initiation until fuel-pin failure occurs. The model, which is used, is substantiated by means of a theoretical analysis of the cause of the typical piston-type bubble generation, and it is checked against water and sodium tests. Typical examples of sodium boiling incidents are given. The probability of occurrence of severe nuclear excursions generated by sodium boiling is calculated.
