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.

A logical first step toward incorporating a precompound nuclear reaction theory in the Hauser-Feshbach formalism, widely used for compound reaction cross-section calculations, is to develop unified level density formulas needed for the two parts of the calculation. An advanced, simplified formulation of the spin cutoff factors for particle-hole level densities, based on the uniform pairing model, is presented. This simplified formula, explicitly dependent on the excitation energy and the exciton number, is easy to use for the precompound part of the calculation and is shown to be consistent with the formula used for the Hauser-Feshbach part of the calculation. Differences between the present approach and a previous one are analyzed.
