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.

Hastelloy X electron beam (EB) weld metal shows higher creep rate and slightly lower rupture strength, and the tungsten inert gas (TIG) weld metal shows remarkably lower creep rate and rupture strength as compared with the base metal. Creep behavior for welded joint is determined mainly by the relation between the welding direction and the loading one, the creep rupture times, and the secondary creep rates of base and weld metal. In applying TIG and EB welding to joints of the shell or tubes, there are few problems for EB welding, but for TIG welding it is necessary to improve the weld metal.
