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 new approach for solving electron transport problems by the Monte Carlo method has been developed. The present approach uses pseudo-reduced single elastic and inelastic scattering cross sections instead of the multiple scattering distributions commonly used in conventional Monte Carlo calculations. Transmission and albedo factors for 1- and 0.5-MeV electrons normally incident on materials of low and high atomic number (aluminum and gold) have been obtained and compared with earlier results. The agreement is reasonably good. The present method is simple and considerably reduces data storage in the computer's memory.
