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.

Perturbation analysis of cross-section differences between the ENDF/B-III file and the KEDAK file helped identify those differences to which keff of large fast systems was sensitive. The interpretation of differences between independently evaluated files as inherent inaccuracies in current experimental data led to recommended requirements for experimental accuracy in 239Pu and 238U fission and capture cross sections.
