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.

New approach to a vacuum ultraviolet (VUV) source based on mirror-confined plasma is presented. A plasma cloud with ne=1016−1017 cm−3 and Te=10–50 eV serves as an active medium. Such plasma can be obtained in GOL-3 facility by means of two-stage heating by relativistic electron beam. Current experiments on GOL-3-II facility are described. Results of recent study of VUV flush from hydrogen and nitrogen plasma with calculations of ionisation balance and radiation power are presented. Transitions in Li-like ions for recombination scheme and in Ne-like ions for collision excitation scheme are considered as a candidates for coherent VUV generation. Prospects of population inversion and gain achievement are discussed.
