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 sodium pumps, intermediate heat exchangers, and steam generators for the liquid-metal fast breeder reactor (LMFBR) SNR-300 were delivered by Neratoom and its industrial partners Royal Schelde and Stork Boilers. All main components were delivered to and erected in the plant between 1983 and 1985 after a long period of delay, caused mainly by continuously changing requirements with respect to the latest state-of-the-art construction and design. It is therefore concluded that to realize an effective manufacturing of breeder components an authorized and final specification is absolutely necessary. After the legal formalization of the licensing step Teilgenehmigung 7/5, it was hardly possible to further change the specification of the SNR-300 components. This led to a speeding up of manufacturing activities; the components were even completed ahead of the new schedules. Therefore, the procedure now foreseen for the post-SNR-LMFBR, to obtain a manufacturing license first before starting fabrication, should be regarded as the most important step toward a commercial LMFBR. The engineering work on the components was accompanied by extensive research and development (R&D) activities. Besides basic R&D work, all components were full-scale tested under SNR-300-like conditions in a 50-MW sodium test facility. The experiences gained from engineering, testing, and manufacturing of the Kalkar components can be used well in the design of the post-Kalkar SNR-2 plant.
