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.

Lithium-lead is a candidate tritium-generating material in conceptual designs of magnetic fusion power plants. Its prolonged utilization, ultimately during the entire lifetime of such a facility, has the potential to minimize amounts of active waste and improve the economic performance. Limits to a prolonged use are production of long-lived radioactive waste and depletion of lithium and reduction of the tritium production rate to levels where self-sufficiency is compromised. The methodology and calculations performed to estimate the transmutation of LiPb following its prolonged irradiation in two of the models in the European Power Plant Conceptual Study are presented. It is shown that no waste requiring permanent disposal is expected regardless of the irradiation length. Time-dependent tritium generation is discussed: Lithium replenishment seems unavoidable, but depletion rates are found to be lower than assumed in the design. The effect of the LiPb flow pattern in the irradiation history proves to be crucial in order to support these results.
