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 electrochemical behavior of La2O3 was investigated in LiF-NaF-KF (FLiNaK, 46.5-11.5-42.0 mol %) eutectic at 700°C. In the electrochemical tests, two kinds of working electrodes, i.e., tungsten and graphite, were utilized. The present study showed that La3+ ions can be deposited in the form of La metal on a tungsten cathode or LaC2 on a graphite cathode, and O2− can be removed in the form of CO/CO2 using a graphite anode. Therefore, a graphite or tungsten cathode (for La3+ removal), and a graphite anode (for O2− removal) are good options to remove both La3+ and O2− from the molten salts. In addition to the electrochemical tests, inductively coupled plasma mass spectroscopy analysis was used to measure the concentration of the lanthanum element and X-ray powder diffraction techniques were applied to determine the chemical forms of lanthanum in the salt. It turned out that the solubility of La3+ in the molten FLiNaK was 6.81 × 10−4 wt% at 700°C and LaOF was formed by the chemical reactions between La2O3 and alkali fluorides during the heating process.
