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.

Radiation measurements were made during recent high power, high neutron yield experiments, and used to calibrate the neutronics simulation of the radiation shielding system. The results indicate that the present radiation shielding is more effective than predicted by the initial design estimates. This is attributed to the effects of changes in the experimental configuration since the initial design and to the design margin included to accommodate initial uncertainties in material properties and distributions. With the present radiation shielding, the production of 5 × 1020 D-T neutrons/yr will result in a total annual dose equivalent at the PPPL property line of less than the 10 mrem/yr design objective.
