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.

An overview is presented of the general status of materials research and development activities related to the needs of controlled thermonuclear fusion reactors. Emphasis is placed on materials research and applications pertinent to magnetic confinement reactor concepts vis-à-vis inertial confinement reactor requirements; this reflects the greater maturity of the magnetic confinement technology programs. The research efforts associated with materials development for first-wall applications are given special attention; in addition, the research and general status of programs aimed at nonfirst-wall or nonstructural fusion reactor materials requirements are also reviewed.
