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.

In an earlier paper we proposed a method for the measurement of subcritical reactivity utilizing reactor noise. The theory has now been applied to the analysis of data obtained with the Berkeley TRIGA Mark III Reactor. A two-delayed-group approximation was found necessary to fit parameters in the expression for the variance-to-mean ratio of the neutron counting distribution. Results were found to be in good agreement with those from control rod calibrations.
