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.

The neutrino transport equation is nonlinear due to the Pauli exclusion principle. Enhanced absorption and spectrum hardening are typical phenomena stemming from this nonlinearity. The numerical methods used for the solution of the linear neutron transport equation were applied to the nonlinear neutrino transport equation. The sensitivity of the total energy leakage to the numerical parameters of a sample problem is presented in detail.
