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 theory is presented to account for the wave energy in lower hybrid current drive experiments when the density threshold for decay into ion cyclotron quasi-mode is exceeded. Immediately above the threshold, convective losses dominate and discrete sidebands are excited. These sidebands have much larger wave-numbers, and strong minority ion heating is possible. Majority ion heating occurs, however, only at high power. At higher densities, ion Landau damping becomes important. The frequency spectrum is non-monotonic in this region with the minimum frequency determined by nonlinear coupling. Majority ion absorption is significant even at moderate power levels.
