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 simple calculational procedure of the kinetic energy distribution of the residual nuclei resulting from nuclear reactions with multiple particle emission is presented. This method can easily be implemented in reaction model codes employed for nuclear data evaluation. Some properties of recoil spectra from neutron-induced reactions are illustrated by means of the reaction 58Ni + n at 40 MeV.
