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.

We have measured detailed axial profiles of electron density, floating potential, and axial magnetic field in the field-reversed configuration (FRC) sustained by the rotating magnetic field. To study the influence on the equilibrium of two kinds of bias magnetic field configuration - straight (pure solenoidal) and mirror -, experiments have been carried out in the FRC Injection Experiment apparatus. The case of mirror configuration has longer quasi-steady state compared with the case of straight configuration. The steeper density gradient outside the separatrix is generated by the uniform gradient of magnetic field due to the mirror configuration. The axial parallel diffusion is suppressed due to the steeper density gradient outside the separatrix. Therefore, the mirror bias magnetic field configuration works to improve the plasma confinement.
