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 separation nozzle process, the enrichment of 235U is achieved by extremely high centrifugal forces in a curved flow of UF6 diluted by a light gas. Remarkable progress has been made in the economy of the process by bringing up the gas pressure and by introducing a nozzle system with double deflection of the jet. While the specific energy consumption is comparable to that of the American diffusion plants, the separation effect per stage is considerably higher than that of the classical technology. Therefore an economical application is possible for smaller and correspondingly cheaper plants. The process finds its first commercial application within the framework of German/Brazilian Cooperation. A so-called First Cascade consisting of 24 separation nozzle stages is under construction in Brazil. The development of components for commercial separation nozzle plants is well under way.
