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 prompt- and delayed-neutron multiplicities for photofission of the eight isotopes, 232Th, 233U, 234U, 235U, 236U, 238U, 237Np, and 239Pu, have been measured using bremsstrahlung with end-point energies ranging from 8 to 13 MeV. The measured multiplicities are compared with those from the same compound nucleus formed in neutron-induced fission where such data exist.
