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 radiolytic gas production rate in boiling water reactors has been reevaluated. The results of recent measurements of the dissolved gases in the main steam samples agree very well with the average production rate measured from the off-gas samples. The best estimate total gas (H2 and O2) production rate is 19.3 ± 0.06 cm3/s-MW(thermal)−1, and the average O2 content in steam is 17.5 ppm. The observed G(H2) and G(O2) values in the reactor core are estimated to be 0.24 and 0.12 molecule/100 eV, respectively.
