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.

Through experimental data of total, nonelastic scattering, elastic scattering cross sections, and elastic scattering angular distributions of Sn, a set of neutron optical model potential parameters is obtained. All reaction cross sections, angular distributions, energy spectra, gamma-ray production cross sections, gamma-ray production energy spectra, especially, the double-differential cross section for neutron, proton, deuteron, triton, and alpha emission, and inelastic scattering cross sections and inelastic scattering angular distributions for low-lying residual nucleus states are calculated and analyzed for n + 112,114-120,122,124,natSn at incident neutron energies from 0.1 to 20 MeV based on measured data and the nuclear model theory, which are an optical, semiclassical model of multistep nuclear reaction processes and distorted-wave Born approximation theory. Theoretical calculations are compared with existing experimental data and other evaluated data from JENDL-3.
