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.

Absolute cross-section measurements for reactions among light-mass nuclei (A < 10) are important in feasibility studies of controlled thermonuclear reactor systems. For a 6Li-d fueled fusion reactor, the 6Li (p,3He)α reaction is of particular interest. The absolute cross sections for this reaction are incomplete and poorly known and have accordingly been remeasured in the range Ep = 3 to 12 MeV. The results support recent measurements below 3 MeV in finding the cross section to be higher in this region than previously supposed. Additional results for the 6Li(p,p)6Li and 6Li(p,p′)6Li* reactions imply the cross sections for these reactions are ∼40% higher than earlier measurements. A plot of the Maxwell-averaged reaction rate parameter, , for the 6Li(p,3He)α reaction is presented as a function of kT, the temperature of a p – 6Li plasma.
