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.

A method for predicting (Z,A,En) is developed and tested against available experimental data for isotopes ranging from 229Th to 249Cf The only input values required are the charge and mass numbers (Z and A) and the binding energy of the last neutron in the (A + 1) nucleus. For incident neutron energies greater than the threshold of multiple-chance fission, the method is extended by accounting for each fission process separately. This method is an extension of work reported by the author in 1963 and 1971.
