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.

A method is described for suppressing secondary electron emission from the negatively biased electrode of a beam direct energy converter by surrounding it with magnetic field lines. Experiments in a positive ion beam converter with a magnetically protected suppressor have shown that the secondary electrons generated by ion bombardment are successfully prevented from leaving the suppressor. It is also found that backscattered ions from the positive electrode occupy a noticeable portion of the loss currents generated in a converter with a copper electrode.
