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.

Uranium-232 production has been calculated in a 1200-MW(e) liquid-metal fast breeder reactor as a function of position, time, and core composition. Whenever thorium is present in the core, large quantities of 232U relative to uranium (∼1000 ppm) are generated, For 232U generated in the blanket, production is on the order of 50 ppm.
