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.

An experimental program was set up at SCKCEN to determine the thermal neutron-induced fission cross section of curium isotopes. These transuranium nuclei are produced in nuclear reactors and are candidates for transmutation. This paper presents our 243Cm(n,f) measurement, yielding a cross-section value of (667 ± 26) b. A detailed analysis of the experimental results published by previous groups is performed, and the renormalized values are compared with our result. In general, a good agreement with old data is observed, questioning the values adopted by different nuclear data libraries.
