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 section of 241Am was determined from transmission data obtained at the Lawrence Livermore Laboratory 100-MeV electron Linac for the neutron energy range from 0.5 to 25 MeV Neutron energies were measured using the time-of-flight technique. The transmission of a 12C sample was measured simultaneously to test the precision of this experiment. The measured 241Am cross section is compared with the evaluated data files, and discrepancies are noted.
