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.
ANS has made every effort to secure the best possible nightly room rate for you at the Double Tree by Hilton. That rate results from a negotiated overall package of event needs including but not limited to sleeping rooms, meeting room space and other requirements.
Please help ANS keep the costs of this event as low as possible by booking your housing needs at the host hotel and through the reservation process created by ANS. Reserving your rooms elsewhere means you are booking outside the contracted room block, jeopardizing ANS’ ability to meet its contracted obligations. Unfortunately, if this happens, event costs will continue to increase if ANS falls short of its minimum room block guarantee. ANS appreciates your support and understanding of this important issue. Thank you!
Nightly Room Rates: $299 + tax
