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.

Among the useful properties of a high TC superconductor (HTSC), the pinning effect included in these properties is considered effective one to reduce a plasma instability in the tokamak reactor. This is because the magnetic flux lines produced by plasma current are trapped in the pinning centers, and the trapping force reduces its motion. However, a proper operating scenario of plasma current ramp-up phase is necessary to achieve a practical stabilizing effect,
This paper proposes an operating scenario of plasma start-up for the purpose of optimizing the stabilization method of tokamak plasma by using the HTSC. The operating scenario was designed by introducing several compensation coils. According to computed results, this operating scenario has fully feasibility.
