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.

Consideration is given to the use of booster rods in a D2O moderated H2O -cooled boiling water power reactor to provide reactivity control to override 135Xe buildup. A booster rod, generally containing highly 235U enriched uranium, is equivalent to a highly effluent fuel assembly. It is shown that the fuel distribution within the most effective booster rod is such that the fuel importance function is flat. Several models of booster rods are evaluated.
