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.

No reaction was observed between B-type 244Cm2O3 and tungsten, molybdenum, or rhenium matrices in cermet compacts fabricated by cold pressing and sintering at temperatures up to 1850°C. Reaction was observed, however, between the oxide and tantalum matrices sintered as low as 1400°C. Cold pressing and sintering at the highest temperatures produced generally well-consolidated Cm2O3 refractory metal compacts of 85% or greater theoretical density. In compacts produced from well-mixed powders, the oxide was distributed uniformly in the metal matrix with little vaporization loss of Cm2Os.
