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.

The (n,α) reaction cross section for 59Ni has been measured at thermal-neutron energies. The experiment utilized dielectric, alpha-particle track detectors and a known thermal-neutron flux. Twelve measurements were made with nickel samples of different thickness and 59Ni enrichment and with track detectors of varying efficiency. The average of all measurements gave the result σ(n,α) (2200 m/sec) = 13.7 ± 1.2 b.
