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.

Electron Cyclotron Resonance Heating by injection of two microwave beams with different k// has been investigated in the GAMMA 10 tandem mirror. In experiments, measurements of an effective temperature of an end loss electron flux and an end plate potential indicate that, for the same total incident power, heating efficiency of two beam heating is a little worse than that for one beam heating. Numerical analysis of electron energy gain by two beam ECRH gives the result of a little worse heating efficiency agreeing with that of the measurements, and the result is able to be explained as spatially sequential heating due to Doppler-shifted resonance gap for two beam heating.
