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.

Interactive graphic techniques have been employed to analyze and interpret the discrepancies found between the integral measurement and the prediction of neutron flux in sodium. Direct adjustments have been made to improve the calculation-experiment agreement in the 10-keV to 1-MeV energy range. In general, the adjusted values for elastic cross sections have been found to be lower than the ENDF/B-IV values. Sensitivity of sodium spectra to the angular distribution of elastically scattered neutrons has also been determined.
