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 total neutron cross sections have been measured and resonance parameters determined for 243Cm, 245 Cm, and 246Cm from 0.01 to 30 eV and for 244Cm up to 90 eV. A total thermal neutron cross section at 0.0253 eV was determined for 244Cm of 23 ± 3 b and 2900 ± 450 b for 245Cm. Resonance absorption integrals of 2345 ± 470 b for 243Cm, 605 ± 40 b for 244Cm and 897 ± 180 b for 245Cm were calculated from the resonance parameters.
