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 241Pu total cross-section measurement of Kolar and Carraro and the neutron fission cross-section measurements of Blons et al. and Weston and Todd were analyzed with the R-matrix resonance analysis program SAMMY, which uses Bayes’ equation to extract resonance parameters from the experimental data. A set of Reich-Moore-type resonance parameters that describes the cross sections up to 100 eV was obtained. It is shown that existing data are not adequate for a precise evaluation of the resonance cross sections, and the need for additional work is discussed.
