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 commercial viability of high field tokamaks is critically dependent upon the development of high field, high energy superconducting magnets. In this paper, superconducting magnet development requirements are discussed in terms of superconducting materials, structural materials and magnet engineering. Superconducting and structural materials are evaluated for processing techniques, properties and applicability to large scale magnets. Both conventional low Tc and high Tc ceramic superconductors are considered. For structural materials, cryogenic steels as well as fiber reinforced composite materials are discussed. The application of advanced materials, in particular high Tc superconductors and fiber reinforced composites, poses unique engineering problems that must be addressed. These problems are exacerbated by the very large stored energy inherent to any large high field magnet. Potential solutions are analyzed and areas of uncertainty are identified. A 30 year development program leading to a 24 Tesla toroidal field coil for a commercial reactor is outlined.
