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 fatigue crack-growth behavior of Type 304 stainless-steel base metal and Type 308 stainless-steel weld metal at elevated temperature was investigated using axially loaded single-edge-notch specimens. The crack-growth rates were determined and are presented as a function of the stress-intensity factor range. Both the base- and weld-metal specimens were tested in the as-received (or as-welded) and thermally aged condition. The results indicate that the crack-growth rates in the weld metal are significantly lower than in the base metal. In addition, aging at 593°C for 1000 h improved the resistance to fatigue crack growth in both the base and weld metals.
