The Thermal Hydraulic Experimental Test Article (THETA) at Argonne National Laboratory is now operating and providing data that could support the licensing of liquid-metal fast reactor designs by validating thermal-hydraulic and safety analysis codes. The new equipment has been installed in Argonne’s Mechanisms Engineering Test Loop (METL), and its first experiments are supporting data validation needs of Oklo, Inc., by simulating normal operating conditions as well as protected and unprotected loss-of-flow accidents in a sodium-cooled fast reactor.

Natrium, a 345-MWe sodium fast reactor with a molten salt energy storage system, was developed by TerraPower and GE Hitachi Nuclear Energy. TerraPower is planning to build the first Natrium demonstration reactor by 2028 with 50-50 cost-shared funding of about $2 billion from the Department of Energy’s Advanced Reactor Demonstration Program. And for the requisite data and testing of reactor components to support that deployment, TerraPower is looking to Japan—a country with decades of experience developing sodium fast reactor designs and testing infrastructure.
