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.

Calculations are presented of the thermal-neutron flux as a function of position in a water moderator surrounding a variety of thick targets which are bombarded by protons in the energy range 540 to 2000 MeV. The calculated results are compared with experimental values, and very good agreement is obtained. Results are also given for the thermal-neutron flux as a function of position in a D2O moderator and for the energy deposition in the targets and the moderators.
