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.

The importance of waste categories other than high-activity waste in the context of long-term risk potential has been increasingly stressed over the last few years. Particular emphasis has been placed on the need for improved techniques for alpha waste reduction, conditioning, and disposal. One way to achieve this is based on an oxalate precipitation technique that recovers the actinides from all liquid alpha waste stream sources. As a result, a fully integrated alpha waste management is conceived that provides a rework unit for plutonium recovery, operating on line with reprocessing and with added incentives, such as savings in fissile material, reduced downtime, reduced medium level liquid waste volumes, and the possibility of confining neptunium and its precursors to a single stream.
