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.

Taiwan’s Maanshan Nuclear Power Station (MNPS) consists of two pressurized water reactors [2775 MW(thermal)]. The reracking method has received licensing approval and has been successfully implemented by the Taiwan Power Company for MNPS to increase the spent-fuel storage capacity of each unit from 746 to 2160 fuel assemblies. MNPS is the only nuclear power station in the world that can store the accumulated spent-fuel assemblies from 40 yr of plant life in its on-site spent-fuel pool after reracking. The safety concerns regarding various aspects of this reracking project are presented. These safety concerns include thermal hydraulics, criticality, structure, radiation, and heavy loads.
