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 total neutron cross section of 182Ta has been measured from 0.01 to 1000 eV using the MTR fast chopper. The observed total neutron cross section at 0.0253 eV is 8200 ± 600 b. Parameters of individual resonances below 30 eV and average parameters at higher energies give a resonance absorption integral of 943 ± 50 b and a neutron s-wave strength function of (1 ± 0.1) × 10−4 (eV) 1/2. The possible use of 182Ta as a neutron temperature monitor is discussed.
