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.

Fabrication and welding methods used to make 217-rod grid spacers for liquid-metal fast breeder reactor application have been developed. Grid straps are formed from cold-worked Type 316 stainless-steel strip material and are assembled into a hexagonalshaped honeycomb grid, using resistance welding. A support strap is then welded onto the periphery of the grid using a manual gas tungsten arc welding (GTAW) process. The grids (11) are then located and appropriately spaced inside a hexagonal duct and attached using an automatic GTAW process. Three of these subassemblies have been completed and are awaiting loading of the fuel rods. After loading, the subassemblies are to be inserted in driver positions of the Fast Flux Test Facility for the acceptance test phase.
