Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

Analysis of process data from initial detritiation tests in a pilot-scale Combined Electrolysis and Catalytic Exchange (CECE) Facility1 indicated that very high detritiation factors (DFs), at least 10 000, could be achieved in the facility. Performance requirements for process equipment were evaluated and some minor refinements were made to selected components. In particular, the recombination efficiency of tritium in the electrolytic oxygen stream was improved and the tritiated-water feed point was moved to a location lower in the catalyst column. With these modifications, the facility was able to remove more than 99.998% of the tritium (i.e., achieve a DF greater than 50 000) from a heavy water feed stream containing 330 GBq/kg, with 7.8 TBq/kg in the electrolysis cell. The processing rate at these conditions was about 2.2 Mg/a, compared with a rate of 5 Mg/a for a DF of 180.
