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.

Excitation of ion cyclotron resonance frequency (ICRF) waves in tokamak plasmas by using the waveguide antenna is investigated. To obtain the surface impedance of the plasma, the wave propagation equation for the fast wave is solved. The reflection/transmission coefficient is calculated for the parallel plates launcher that simulates the ridged waveguide. Dependence of the transmission coefficient on geometrical and plasma parameters is studied. It is found that the transmission coefficient can be of the order of 10%, comparable to that of the loop antenna. Non-plasma loss of the launcher is also discussed.
