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.

The design of a cooling system for a power plant is approached as a problem in systems synthesis. The cooling system is optimized with respect to both the independent variables associated with each cooling unit and the arrangement of the cooling units in the system. A sample cooling system is optimally synthesized with two methods of systems synthesis—a structural parameter problem formulation with a direct search and a dynamic programming formulation. Other approaches are also considered. Two types of cooling units—a mechanical draft cooling tower and a cooling pond—are used in the example. The methods proposed for the development of the optimal design are sufficiently general so that any number, type, or combinations of types of cooling units could be included in the optimal systems synthesis.
