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 catalyzed exchange reaction between liquid water and hydrogen gas has been studied using a hydrophobic catalyst of platinum deposited on a porous Teflon support. The reaction was studied with a new method in which a mixture of water mists and hydrogen gas moves downward through the catalyst bed co-currently. This new method was employed to improve the poor contact efficiency between liquid water and hydrogen gas in the hydrophobic catalyst bed. It was found that the reaction rate increased an order of magnitude over the conventional method in which liquid water and hydrogen gas react countercurrently. These experimental results have been analyzed in terms of a rate determining step and compared with previous ones.
