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.

Fewer neutrons are produced from 11B(11B, n) than from 11B(p, n)11C for temperatures from 100 to 800 keV. For temperatures below 300 keV, 11B(d, n)12C produces more neutrons than either of these reactions if the normal isotopic mixture of hydrogen is used. Potentials generated by the double-folding method and tested against 7Li + 7Li data were used to generate 11B + 11B cross sections for energies where there were no measurements.
