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 thermal-neutron capture cross sections for the reactions 128Te (n,γ) 129gTe and 128Te (n,γ) 129mTe have been measured by a neutron activation method, using gold as a standard. Samples of powdered tellurium enriched to 96.5% in 128Te were measured by gamma spectrometry. The found values are 199.7 ± 8 and 16.1 ± 0.7 mb, respectively. The resonance integrals have been calculated by irradiating tellurium and gold, or cobalt, with and without cadmium covers; their values are 1.48 ± 0.13 b and 77.4 ± 5.2 mb, respectively.
