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 survey of plasma-type neutron sources is presented. Mirror devices are found to be most suitable for use as a neutron source because their high-β values allow a high-intensity flux of 14-MeV deuterium-tritium neutrons at a moderate plasma size. Mirror devices also have a convenient geometry for radiation tests. A conceptual design and performance of a neutron source based on the gas dynamic trap are described. Components (neutral beam injectors, tritium system, etc.) of the plasma-type neutron source are compared with those of the International Thermonuclear Experimental Reactor (ITER) facility. It is shown that the current level of technology is sufficient for construction of a mirror-based neutron source.
