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.

Corrosion current transients synchronized with the cyclic strain were observed when AISI Type 316 stainless steel plate was strained by reverse bending at 24 Hz in selected aqueous media. This was accomplished by extracting for oscilloscope display the regular fluctuating component of the corrosion current flowing when the sample was polarized to prescribed potentials. The amplitude of the cyclic current transient could be correlated with the expected stability of the passive condition of the steel when it was polarized to potentials within its passive range. Chloride ions increased and chromate ions decreased the amplitude of the signals. These results are interpreted as providing evidence that (a) the dominant stress-environment interaction for this material is strain-induced rupture of the passive film at persistent slip bands, accelerating crack initiation and (b) the chemical depassivating or passivating influence of the environment is additive to the mechanical depassivating effect of the applied cyclic stress.
