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 rotating gas cell has been developed as a target for charged-particle beams to produce monoenergetic neutrons via the reactions 1H(t,n), 2H(d,n), 2H(t,n), 3H(p,n), and 3H(d,n). An intense monoenergetic neutron source results when this cell is equipped with a rugged entrance foil and pressurized to 1 MPa, and when a prolific source reaction such as 1H(t,n) is chosen. Neutron flux levels of typically 4 × 109 cm-2 ·s-1 between En = 8 and 12 MeV are being used to measure activation cross sections.
