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 attempt is made to describe the in-process inventory of enrichment cascades with a close separation process as a product of gas in-flow and the average holdup time of gas molecules. The holdup time is calculated on the basis of a simple random-walk model of the transients and the output response to input perturbation. Calculations are carried out for a gaseous diffusion plant producing slightly enriched uranium. Experimental determination is proposed for safeguards purposes.
