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.

Absolute cross sections for the 6Li + 6Li ⇒ 34He reaction have been measured for center-of-mass energies from 0.5 to 2.75 MeV. Thermonuclear reaction rate and reactivity parameters have been calculated for kT values from 10 to 1000 keV. At the higher energies, the reactivity parameters are comparable to those of other potential fusion reactions.
