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 automated startup of a boiling water reactor (BWR) plant is discussed. A startup procedure and a logic representation of the operational guidance given in current BWR plants are examined. Based on these examinations, a knowledge representation of the sequential operations is proposed. Plant startup is a process in which various plant functions are brought in to establish an operational plant state. Based on this understanding, the relationships between plant functions can be used to deduce a BWR plant operation procedure. Finally, the proposed knowledge representation is evaluated using a prototype system, and it is shown that the representation is very effective in the startup of an automated BWR plant even if abnormalities arise during operation.
