Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

The validity conditions of compartment models for cesium migration in soils are investigated. A compartment model is derived from a diffusion-convection model. The model considers free and bound cesium compartments and is applied to measured profiles of 137Cs of undisturbed soil in Northern Greece. It is concluded that the rate of cesium transfer must vary linearly with depth and that from measured equilibrium profiles, the ratios of model parameters can be determined but not the parameters themselves.
