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 fusion ignition experiment will produce large numbers of neutrons and alpha particles. The detection and characterization of these particles will be important in understanding the physics of ignited plasmas. The methods for detection of neutrons are well developed, but detection and characterization of alpha particles may prove more difficult in a high-availability fusion ignition experiment. The proposed systems for the IGNITEX experiment are chosen to be simple and reliable. The systems include a foil absorption system for escaping alpha detection, a foil activation system for total neutron count, and a time-of-flight spectrometer for real-time neutron count and for neutron energy spectra.
