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.

Double-differential neutron yields from 400 MeV/nucleon 56Fe stopping in C, Al, Cu, and Pb targets are reported, along with Particle and Heavy Ion Transport Code System (PHITS) transport model calculations of the data. The yields were measured at 90, 120, and 160 deg in all four systems. Neutron energies were measured from 1 to 2 MeV up to a few hundred mega-electron-volts. The data augment previous measurements made by Kurosawa et al. that were reported for angles between 0 and 90 deg. The measurements for each target were made at two different target orientations, resulting in two different thicknesses of target that neutrons had to traverse before reaching the neutron detectors. The differences in the spectra between two different target orientations are due to neutron transport through the target and as such provide an interesting test of transport model calculations. The data indicate that PHITS reproduces the effects of neutron transport very well but may overestimate neutron production between energies of 10 to 50 MeV in some cases.
