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.

Precise cross sections were measured for the 90Zr(n,)87mSr, 94Zr(n,)91Sr, 92Mo(n,)89m+gZr, 45Sc(n,)42K, 51V(n,)48Sc, 59Co(n,)56Mn, 93Nb(n,)90mY, 92Mo(n,p)92mNb, 96Mo(n,p)96Nb, 97Mo(n,p)97m+gNb, 90Zr(n,p)90mY, 91Zr(n,p)91mY, 92Zr(n,p)92Y, and 60Ni(n,p)60m+gCo reactions in the 7- to 14.7-MeV neutron energy range. Excitation functions were completed with a number of new differential data.Spectrum-averaged (n,) and (n,p) cross sections were measured for the 54Fe(n,)51Cr, 68Zn(n,)65Ni, 27Al(n,)24Na, 58Ni(n,p)58m+gCo, 64Zn(n,p)64Cu, 59Co(n,p)59Fe, 94Zr(n,p)94Y, 56Fe(n,p)56Mn, 46Ti(n,p)46m+gSc, 47Ti(n,p)47Sc, 48Ti(n,p)48Sc, and 62Ni(n,)59Fe reactions in addition to those aforementioned using a thick target Be(d,n) neutron field at Ed = 9.72 MeV. Results were compared with the ENDF/B-VI, IRDF90, JENDL-3, BROND, JEF-2, CENDL-2, and ADL-3 data files and the SINCROS-II system for testing the validation of differential data and the nuclear model calculations.
