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 scattering cross sections were determined experimentally for more than ten elements in the energy region between 8 and 14 MeV. Comprehensive measuring and data analysis methods were elaborated to obtain cross sections with the highest precision presently possible. The experimental procedure was extended in such a way that cross sections of the complete neutron emission spectrum ranging down to the energy of 1.5 MeV could be derived, thus overcoming the problems usually arising when a nonmonoenergetic neutron source is applied. Typical results are selected for discussion and comparison with the results of other authors and with results taken from several libraries of evaluated neutron data.
