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.

Creep rupture tests on six candidate alloys for intermediate heat exchangers of high-temperature gas-cooled reactors were carried out at 1173 to 1323 K in helium with small amounts of H2, CH4, CO, and C02, and at 1173K in H2 + 15% CO + 5% C02. The creep rupture strengths of each alloy were scarcely different at 1173 K in both environments. At higher temperatures in helium environments, the degradation of the creep rupture strengths appeared in carbide-strengthened alloys because of decarburization. The alloy, which mainly uses α-W as a strengthener, showed stable creep rupture strength up to 1323 K in spite of severe decarburization.
