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.

Steady-state and hybrid-mode operation of a tokamak fusion reactor is investigated by power balance calculations, and operation points are optimized with respect to divertor heat load. The dependence of the divertor heat load on a variety of models is also discussed. Several schemes to reduce the heat load are investigated, and the goal of physics research and development is clarified. Hybrid-mode operation appears to be suitable for technology testing, which requires a long burn time and a high neutron wall load. The divertor heat load can be reduced to the ignition-mode level without impurity seeding if the energy confinement is enhanced by 10%. The relation between the divertor heat load and the controllability of the current profile, that is, the fraction of the beam-driven current, is also discussed.
