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 theory of pulsed neutron experiments for thermal, nonmultiplying polycrystalline media is presented. Existence theorems for discrete eignevalues are examined together with the role of various continua. It is found that discrete eigenvalues can exist with values greater than the minimum collision frequency. A new continuum contribution, directly related to elastic scattering, provides a bound for the discrete eigenvalues in small assemblies.
