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 results of a recent measurement of the neutron fluence at the vessel outer boundary of the Caorso Nuclear Power Plant show that the neutron flux per unit power was not constant during the reactor operation. This effect, usually not mentioned, may induce serious errors in the results of neutron dosimetry by the multiple foil activation technique.
