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.

Cross sections for the production of gamma rays by bombardment with 14.2-MeV neutrons were measured for 20 samples ranging from beryllium to plutonium. Differential cross sections are given as a function of gamma-ray energy over the region from 0.2 to 9.0 MeV for angles between the incident neutrons and emitted photons of 90 to 130 deg. For some of the light elements, cross sections are also presented for individual gamma rays. Pulsed-beam neutron time-of-flight techniques were employed to reduce background effects in the large NaI(Tl) gamma-ray spectrometer.
