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 decay schemes for a few of the radionuclides of potential importance in routine releases from nuclear fuel cycle facilities may contain significant uncertainties with regard to applications of the decay data to radiation dosimetry. These radionuclides include 92Sr, 115Cd (44.6 day), 133Te (55.4 min), 141La, 142Ba, 166Ho (1200 yr), 229Th, and 245Cm. The sources of uncertainty in each decay scheme are discussed, and additional measurements are proposed.
