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.

A position-sensitive neutron detector is used to measure the differential cross sections of 14.8-MeV neutrons from iron, nickel, and chromium scattered in the angular range of 2.5 to 16 deg. The data are corrected for flux attenuation, multiple neutron scattering, and finite geometry by the Monte Carlo method. The angular distributions are calculated with the coupled-channel code ECIS79. The measured and calculated results are compared and discussed.
