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.

Previous work on the automated selection of refueling patterns under equilibrium conditions has been extended to situations where operational difficulties or changes have been encountered. The approach has been embodied in the REFUEL computer program, which is capable of determining the refueling pattern to be used with conventional boiling water reactor cores or the newer minimum shuffle control cell core configuration.
