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 of KrF laser issues for fusion in the laboratory environment is presented. In this fusion method, lasers are used to compress the deuteriumtritium fuel in the pellet to several thousand times its initial density. Krypton-fluoride lasers offer favorable wavelength, bandwidth, pulse-shaping, efficiency, and high-repetition rate properties for achieving fusion. Large-scale demonstration plants for fusion, however, rely on the improvement or resolution of significant issues: front-end capabilities, amplifiers and amplifier scaling, optical engineering for the ultraviolet, alignment systems, kinetics, beam quality, target coupling, cost, and overall system factors. We feel that KrF lasers may be able to meet the required inertial confinement fusion driver characteristics, driver-target coupling particularities, and capsule physics issues necessary to achieve the final conditions in the implosion that will produce net energy release from the fusion reaction.
