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.

With reference to loss-of-coolant accidents in light water reactors, the critical flows of subcooled liquids are examined, particularly from the viewpoint of the time extension of the metastability state. “Ad hoc” tests have outlined an upper limit of this time range at 10−4 s. The flow characteristics of the unbounded jets have been investigated both externally (via photographic measurements of the external shapes at various subcoolings) and internally (via pressure profiles in the radial direction). As far as pressure profiles within the jet are concerned, the presence in the jets characterized by the subcooled inlet conditions of a central liquid core gradually evaporating has been outlined.
