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.

Neutron emission spectra from targets bombarded by 14-MeV neutrons have been calculated using three nuclear models. The elements studied included aluminum, iron, copper, nickel, and niobium and were selected because of their potential importance in fusion reactor design and because measured cross sections and evaluated cross-section libraries were available for comparison with the calculations. Contributions from statistical, pre-equilibrium, and direct reactions are included to achieve a good fit to the data. The calculated spectra are also compared with the predictions of the ENDF/B-IV and the Livermore ENDL neutron libraries.
