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.

An electrolytic plutonium decontamination process for stainless steel was developed for use as the final step in a proposed radioactive waste handling and decontamination facility to be constructed at the Rockwell International Rocky Flats plutonium handling facility. The process utilizes a basic (pH > 7) electrolyte which has been patented (U.S. Patent 4 193 853). Filtration can be used to separate most radioactive contaminants and dissolved metal from the electrolyte. A test plan was executed comparing the basic electrolyte with phosphoric acid and nitric acid electrolytes. Laboratory-scale testing was done with stainless steel exposed to plutonium and americium. The alpha activity was reduced to <0.14 dis/min-cm-2. The amount of wet sludge generated with the basic electrolyte was ∼170 mg/cm2 of surface decontaminated.
