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.

Two techniques have been developed for the underwater dismantlement of the steel components of the Japan Power Demonstration Reactor (JPDR): the plasma arc for dismantling the reactor internals and the arc saw for cutting the reactor pressure vessel. In parameter tests, the cutting capability for these techniques was improved, and the characteristics of the byproducts were evaluated to enable proper design of the water purification and dross collection systems. Mockup tests, conducted as final systems performance checks, proved that the cutting systems developed are practical for dismantling the JPDR steel structures.
