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.

In the High Average Power Laser (HAPL) program, we have developed an integrated target tracking and engagement system designed to track an inertial fusion energy target traveling 50-100m/s in three dimensions and to steer laser driver beams so as to engage it with ±20 m accuracy from a stand off distance of ~20 meters. The system consists of separate axial and transverse detection techniques to pre-steer individual beamlet mirrors, and a final fine-correction technique using a short-pulse "glint" laser to interrogate the target's position 1-2 ms before the target reaches chamber center.We are working to demonstrate the viability of this concept by conducting a table top engagement demonstration at reduced speeds and distances. Integration of the various components has been completed and hit-on-the-fly experiments are now being conducted. Initial engagement efforts from a simulated driver beam overfilling a falling target yielded a 150-m standard deviation for targets placed ±1.5mm from chamber center. Since then, our efforts have focused on systematically defining and eliminating all sources of error in each component and subsystem. Current engagement accuracy is 42m RMS. The engagement effort and the step-wise improvements realized are reported, as well as the path toward our goal.
