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.

U. S. Department of Energy, Retired
Alex Larzelere is the former Federal Director for the DOE Office of Nuclear Energy’s Modeling and Simulation Energy Innovation Hub. As such, he was involved with developing the original vision, writing the Funding Opportunity Announcement, and conducting the Merit Review Process that resulted in CASL. Over the next six years, Alex executed the “light federal touch” for the oversight of the Hub. Alex has been involved with advanced computing and modeling and simulation for about 30 years in a variety of roles. These include, running technology transfer programs, helping to start the Accelerated Strategic Computing Initiative (ASCI) for the simulation of nuclear weapons, working for private industry, and starting his own companies.
He is the author of, “Delivering Insight, the History of the First 10 Years of ASCI”. Also, Alex served in the U.S. Coast Guard, sailing on cutters in Southeast Alaska. He is a graduate of the U.S. Coast Guard Academy. Alex Larzelere is now retired, traveling with his wife, Mary Ann, playing with his grandson, and writing his memoirs.
