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.

In the GAMMA10 tandem mirror, waves with ion cyclotron range of frequency (ICRF) have been used for plasma production and heating. Magneto Hydro Dynamic (MHD) stability is kept with the anchor cells which have minimum-B configuration. In a typical discharge, plasmas in the anchor cell are heated with ICRF waves excited by Type-III antennas installed in the central cell. In order to produce high performance plasma, anchor heating should be enhanced. Double-Arc Type (DAT) antennas are installed in both east and west anchor cells. In this study, direct heating experiments in both east and west anchor cells with DAT antenna are performed. DAT antenna is driven with the different frequency from Type-III antenna and driven with the same frequency. In the same frequency case, the phase difference between both antennas can be changed. In both the different and the same frequency cases, the increase of the line density is clearly observed in the central and anchor cells. Stronger effects are observed in the east anchor than in the west anchor.
