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.

An instrument has been developed to continuously measure the steam content in flowing steam/air mixtures. This instrument is nonintrusive and thus can be used in existing and proposed future experimental facilities in such a way as to not affect the flow field. The instrument detects the steam content by measuring the differential attenuation of infrared radiation passing through the flowing fluid. A small steam/air test facility has been designed and constructed and was used to calibrate this instrument. Experiments have indicated an instrument accuracy of ±5% in the measurement of steam/air fraction. This is particularly impressive considering the small (1.9-cm) steam/air attenuation path utilized.
