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 mathematical model is derived for correlated neutron signal multiplets. These multiplets are expressed as functions of the spontaneous fission rate, of the neutron detection probability, of the probability that a neutron generates a fast fission, and of nuclear data expressing fission neutron emission probabilities. For the moments of the correlated multiplets, simple analytical expressions are obtained with the assumption of an exponential detector response function. These moments permit multiparameter determination.
