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 response of a truck package to a radiation fire model is simulated for a range of fire durations using three-dimensional finite element analysis. A model is developed to determine the cumulative seal degradation from its temperature-versus-time history. This model is used to determine the minimum fire duration that causes the seal to lose containment integrity. The fire durations that cause the cladding to reach its long-term creep deformation and burst rupture temperatures are determined and found to be longer than the durations that cause the seal to lose containment integrity. These simulations are repeated for package models without the compliant regions of the impact limiters, and for a package with the impact limiter completely removed. Those simulations quantify the level of thermal protection the impact limiters provide to the seals and cladding during simulated fires.
