Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

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.
