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.

A model calculation of neutron activation cross sections is carried out with SINCROS-II for all stable isotopes of molybdenum. Results of the calculation are compared with experimental data, which were measured over the wide range from threshold to 20 MeV. The general agreement between the calculated and experimental cross sections is good, but some cross sections remain in significant disagreement. The calculational method is applicable to the estimation of production cross sections for the long-lived radioactive nuclides.
