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.

Gamma radiation fields grow with time on the piping and other components in the primary circuit of all water-cooled nuclear reactors. Corrosion products that have been released from the out-reactor surfaces, made radioactive in the core, and then deposited on out-reactor surfaces cause the fields to grow. Corrosion product deposits on fuel sheaths exposed to nonboiling water in an in-reactor loop test are used to show the importance of high-temperature pH in the process of corrosion product transport. A possible mechanism for radiation field growth in light water reactors is then deduced from this test.
