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 meteorological information system is operated at the Kernforschungszentrum Karlsruhe (KfK). It consists of a tower equipped with instruments and a data processing system. An essential feature of software is the real-time computation of the local and temporal distribution of near-ground activity concentrations in the environment of KfK. After accidental activity releases, the display of concentration distribution serves to initiate concerted intervention.
