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 reactor blanket having a large tritium breeding ratio (TBR) is proposed. The blanket has a front breeder zone on the plasma side near its multiplier. A suitable zone thickness is 1 cm when 6Li enrichment is 50%. Combined with a multiplier composed of only ∼18-cm-thick beryllium, the TBR is maximized at a value over 20% larger than that of a blanket without a front breeder zone. Since the beryllium multiplier is supposed to include 5% of SUS as structural material in addition to cooling channels, a 12-cm-thick multiplier gives the maximum TBR as >1.4 for the blanket with the front breeder zone.
