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 new computer program, PLENUM-2A, has been developed to predict the conditions in the outlet plenum of a liquid-metal fast breeder reactor after a transient scram. This program divides the transient into three main consecutive discrete states. Two additional stages, one occurring before the transient begins and the other occurring as the transient ends, are also considered. The three main stages are described in detail, and calculations and experimental results are compared. The agreement between the calculations and experimental data is very good.
