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.

Two techniques for measuring the effective delayed neutron fraction have been developed. The techniques are based on a combination of the Rossi-α technique and the source-multiplication technique. They require minimal knowledge of the assembly, use variables that can be measured, and are independent of the detector efficiency and the neutron lifetime.
