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.

Cell homogenization methods for the neutronics analysis of the blanket region of a plate-type liquid-metal fast breeder reactor critical assembly are investigated, and an improved method is proposed, which calculates cell-averaged cross sections so as to preserve groupwise reaction rates in each cell in a multidrawer cell model. The present homogenization method has been applied to the analysis of the heterogeneous fast critical assembly ZPPR-13. It was found that the keff difference between homogeneous and heterogeneous fast critical assemblies was reduced from 0.4 to 0.2% Δk/k by using the present method.
