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 removal of deuterium retained in boron, titanium, and titanium oxide films by neon glow discharge was investigated. The films were exposed to deuterium glow plasma to retain the deuterium and subsequently exposed to neon glow plasma. The temperature of the exposures was room temperature. The residual deuterium was estimated by thermal desorption spectroscopy. The removal ratio of deuterium by neon glow discharge largely depended on the material. Namely, the ratios for boron, titanium, or titanium oxide were 14%, 2%, or 40%, respectively. The ratios for the boron and the titanium oxide roughly agreed with the estimation from SRIM code calculations, while the ratio for the titanium did not agree with the estimation. These results suggest that the reduction of the deuterium retention is owing to the etching and the ion impact desorption of neon ions in the cases of boron and titanium oxide, and the prompt re-trapping of deuterium by titanium atoms might occur in the case of titanium. The comparison between titanium and titanium oxide clearly shows that the removal effect by glow discharge largely depended on the surface conditions, such as oxygen impurity.
