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.

We use molecular dynamics simulations to study the irradiation-induced point-defect clustering kinetics in CeO2 as a surrogate for UO2, the most widely used nuclear fuel. Remarkably, the cluster-formation mechanism involves a partial self-healing response of the perfect crystal to the radiation-induced defects, by spontaneous creation of new point defects with negative formation energy. These "structural" defects neutralize the cluster by screening its long-range Coulomb potential, thereby localizing the damage. The observation of a similar lattice response in MgO and UO2, in spite of very different types of clusters involved, suggests that this partial self-healing screening behavior may be intrinsic to all ionic crystals.
