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 analysis of two 91Zr neutron transmission experiments performed some years ago at the Oak Ridge National Laboratory and Geel electron Linacs showed systematic discrepancy in the resonance neutron width estimation. The two sets of data are comprehensively reanalyzed by a shape least-squares method that builds up a single system of normal equations. An accurate resolution function description was obtained by Monte Carlo calculation of the moderation and detection contributions. The two experiments are found to be in complete agreement and a single set of resonance neutron widths is obtained.
