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 kinetics of a flux-trap cylindrical reactor system were studied both theoretically and experimentally. A state-variable approach was used to develop a twenty-fourth-order model describing neutron and temperature kinetics in 14 regional system components. The modified Mikhailov method was used to determine the stability of the model. The reactor system was studied using step testing and pseudorandom multifrequency binary sequence testing procedures with a small-computer based instrumentation system. Measurements were made at powers of 1, 2.5, and 4 MW. The frequency response analysis of the system model compared favorably with experimental observations.
