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 transient velocity difference model called the dynamic slip model has been integrated into the FLASH-4 numerical scheme. The numerical scheme resulting from combining this model with the general purpose RELAP4 network computer code is described. The result is a code that calculates slip in all junctions both vertical and horizontal. Results of computations are compared to U.S. Nuclear Regulatory Commission standard problems 1 and 6.
