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.

Deviations from normal mechanical properties observed in stainless steel irradiated by neutrons have been attributed to the production of helium in neutron reactions with nickel. A measurement of the thermal-neutron cross section for the 59Ni(n,α)56Fe reaction has been made in which the alpha-particle emission was determined by a silicon surface-barrier particle spectrometer. The 2200 m/sec cross section obtained is 18.0±1.6 b. This value disagrees with 13.7 ± 0.6 b reported earlier by Eiland and Kirouac.
