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.

Some solutions of the differential equations, which describe an elementary model of the disposition of material carried by a fluid flowing in a pipe, are derived and investigated. The solutions pertain to a variety of assumptions made regarding the initial concentrations of the material in the fluid within the pipe and on the pipe interior surface, and the concentration of the material in the fluid entering the pipe. The means of obtaining some of the model parameters using the derived solutions and measured values of the concentrations of matter on the pipe surface and in the fluid are illustrated.
