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.

Borate waste is the main liquid waste generated by nuclear power plants (NPPs). Vitrification is conceptually attractive because of the potential durability of the final product, the flexibility of the process in treating a wide variety of waste streams, and the economy of large volume reduction. The vitrification of borate waste from NPPs, including the glass formulation and product characterization, is examined. The Minimum Additive Waste Stabilization (MAWS) concept was utilized to design the glass formulation. The glass formulation named SL-1, which can incorporate 45 wt% of waste oxides, was selected. The SL-1 glass has good chemical stability, the melting temperature is 1000°C, and the viscosity of molten glass is ~5.0 Pas at 1000°C. The borosilicate glass form could satisfactorily solidify borate waste with high volume reduction.
