TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The lack of progress with the back end of the fuel cycle in the United States has been a source of great frustration to most parties involved, including industry, regulators, and governments at all levels. With the Yucca Mountain project going nowhere, calls for "consent based siting" have re-emerged despite a lack of consensus on what it means in our system of government. Over the next few months, the Biden Administration is expected to put forward its proposals for a new approach. Private used fuel consolidated interim storage facilities are expected to receive licenses this year, but both face opposition from their host states. Alternative technologies to conventional direct disposal are part of the discussion again. Informed panelists representing important constituencies will offer their insights into how the country may be able to move forward again with an integrated approach to nuclear waste management.
