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 fission reactor safety concept providing for fission excursion abatement following a temperature excursion is here described. This concept is based on the in-situ placement of trigger isotopes in the core which upon a temperature excursion promptly breed strong neutron absorbers thereby generating negative reactivity. No external controller action is necessary.
