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 neutron capture and subthreshold fission cross section of 241Am was measured in the energy range from 10 to 250 keV, using 197Au and 235U as the respective standards. Neutrons were produced via the 7Li(p,n) and the T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon-Rae detector and fission events by a NE-213 liquid scintillator with pulse-shape discriminator equipment. Flight paths as short as 50 to 66 mm were used to obtain optimum signal-to-background ratio. The capture cross section could be determined with a total statistical and systematic uncertainty of 4 to 10% while the respective values are 13 to 20% for the fission cross section. The results are compared with recent data of other authors, which in some cases are severely discrepant.
