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.

In the GAMMA10 tandem mirror, the first pellet injection experiments in open systems have started.1 The tandem mirror machine is suitable for measuring propagation of pellet-fueled particles along the magnetic field lines. We observed a very low frequency oscillation in various diagnostic signals from the plasmas with a pellet injection. The frequency of the oscillation is a few hundred Hz. It is found that the phase of those signals changes to anti-phase at a certain place. The oscillation continued during plug-ECH for the formation of confining potential and its amplitude decays within a several ms after the end of ECH pulse. Measurements at several locations along the field lines indicates that this oscillation is a standing wave along field lines of plasma density perturbation due to the pellet injection. The wavelength of the oscillation is estimated to be about 6m. The oscillation has mode number n = 3.
