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 possibility of obtaining ignition in the Tokamak Fusion Test Reactor (TFTR) by means of very centrally peaked density profiles is examined. It is shown that local central alpha heating can be made to exceed local central energy losses (“central ignition”) under global conditions for which Q 1. Time-dependent one-dimensional transport simulations with a simplified transport model show that the normal global ignition requirements are substantially relaxed for plasmas with peaked density profiles. More realistic simulations with recently developed profile-consistent microinstability based models for electron and ion confinement show that TFTR may form a small centrally ignited region if peaked central density can be maintained.
