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.

In the framework of the Paul Scherrer Institute (PSI) transient analysis project STARS, a boiling water reactor (BWR) stability analysis methodology based on the BWR system code RAMONA3 has been developed. The time series analysis based on parametric mixed autoregressive/moving average models is conducted by a MATLAB code package using the system identification and the signal-processing toolboxes of MATLAB. A short description of the PSI methodology is presented and two aspects of the stability analysis are discussed. First, the physical mechanism underlying the BWR power oscillations from the nonlinear feedback system point of view is discussed, and second, some experiences collected by the analysis of the regional stability phenomenon are presented.
