Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 capture by the heavier stable ruthenium isotopes and by natural rhodium has been measured at the Oak Ridge Electron Linear Accelerator time-of-flight facility up to 500 to 700 keV. Most of these isotopes are important as fission products. Strength functions S0, S1, S2, and Sγ were fitted to the average cross sections derived for the pure isotopes up to 113 keV. Resonance parameters were fitted for ∼100 cross-section peaks for each isotope.
