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 study of the properties of the neutron production target for the China accelerator-driven system induced from 150-MeV incident proton energy and a 3-mA beam current is performed. The selection of the material and geometry design for the target; the physics properties of the target involved in this work including the neutron yield, energy, and space distribution for the neutrons leaked from the target; and the spallation fragment of charge and mass distribution have been investigated using the SHIELD code. An analysis of the target radiation damage and energy deposit is also carried out.
