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 500-MW(electric)-capacity Prototype Fast Breeder Reactor (PFBR) using sodium as a coolant is under construction at Indira Gandhi Centre for Atomic Research, Kalpakkam, India. Instrumentation for the measurement of physical and chemical characteristics of liquid sodium in reactor coolant and related applications is described. Various properties of liquid sodium are used for measurement of flow, temperature, level, and leaks. Temperature-dependent solubility of impurities in the liquid sodium is a basis principle of instruments for monitoring the general purity and the specific impurities of oxygen, hydrogen, and carbon. This technical note deals with the properties of sodium that are relevant to successful sodium instrumentation used for PFBR.
