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.

Neutron capture and transmission measurements were made on a sample of fission product palladium. The level parameters were obtained for 34 107Pd resonances below 700 eV. The observed average level spacing was 〈D〉 = (10.7 ± 1.5) eV, and the s-wave neutron strength function was determined to be 104 S0 = . The capture width Γγ for the 6.834-eV 107Pd resonance was deduced to be (125 ± 15) meV. Assuming that all 107Pd resonances have the same radiation width as the 6.834-eV resonance, the resonance capture integral for all 34 resonances is 87 b.
