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.

The behavior of tritium on the surface of various piping materials is discussed considering the various mass transfer steps. It is observed in this study that the isotope exchange reaction between gaseous hydrogen in gas stream and surface water and transfer of hydrogen isotopes and water through surface layer formed on materials or pores are most effective when an oxide film layer is formed on a material surface such as stainless steel. The amount of tritium sorbed on the stainless steel is correlated and compared with that observed for copper or quartz. The memory effect observed for an ionization chamber having stainless steel electrodes is also compared with that having copper electrodes.
