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.

In the functional description of the ductile-brittle transition of ferritic steels, the authors assumed in an earlier paper that the increase of material fracturing in the ductile fracture mode with the increase of temperature follows a Gauss distribution function. In this paper, evidence is presented that justifies this assumption for the pressure vessel steel 20 MnMoNi 55 (A533 B Cl.1).
