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.

Experiments to determine the mass transfer efficiencies of the packed columns making up the Krypton Absorption in Liquid CO2 (KALC) process were performed at a nominal pressure of 2 MPa over a wide range of flow rates and flow ratios for the CO2-O2-Kr system. The height of the transfer unit values, which were relatively independent of gas or liquid flow rates, were 0.13 m for krypton in the absorber, 0.16 m for O2 in the fractionator, and 0.21 m for krypton in the stripper.
