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.

A fission gas sampling device for selectively locating leaking TRIGA reactor fuel elements was developed. The device, and the associated scintillation spectrometer, measures the radioactivity of the particulate daughter products of the fission gases escaping from a single failed fuel element. Details of the design of the device and the operating procedures are described. Several different approaches for locating faulty elements were evaluated and the most suitable one was used to locate a fuel element cladding break in the TRIGA reactor of the University of Texas at Austin.
