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.

The near-equilibrium energy spectrum of the delayed neutrons from the fast neutron-induced fission of 240Pu has been measured over the energy range from 40 to 1500 keV. The spectrum is somewhat similar in shape to near-equilibrium spectra previously reported for other isotopes, and the peak structure is consistent with results from both fissionable isotopes and from various individual delayed neutron precursors.
