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 approximate method is developed to allow S(&alpha, β) thermal collision contributions to next-event estimators in Monte Carlo calculations. The new technique is applicable to the more general problem of contributions to next-event estimators from any discrete probability distribution. The method is incorporated into the MCNP Monte Carlo radiation transport code.
