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 neutron-induced nuclear reactions of 46,47,48,49,50,natTi are calculated and analyzed for the CENDL library. First, one set of optimized optical model potential parameters for n + 46,47,48,49,50,natTi below 20 MeV is obtained. Based on these parameters, the complete neutron data are computed though the UNF and DWUCK4 codes for each of the Ti isotopes and the natural nuclide. All of the theoretical results are compared with the experimental data, together with the updated evaluations of other evaluation libraries. In addition, we verify the new results through the benchmark integral measurements from OKTAVIAN.
