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 feasibility of using a fast pulse reactor as a neutron source in the production of time-resolved neutron radiographs has been demonstrated at the U.S. Army Pulse Radiation Facility. The radiographs were obtained using the transfer radiographic method. Pulses with a full width at half maximum of 50 µsec and 1.2 × 1017 fissions were utilized to obtain time-resolved radiographs of objects moving at speeds up to 76 m/sec. Investigation of double images, observed in radiographs of test objects moving within this speed range, suggests a method of producing “motion pictures” of these objects using one reactor pulse and a suitable stack of detection foils. Resolution of objects moving at speeds greater than 76 m/sec can be obtained by reducing source exposure time to a lower limit of 1 µsec through employment of electronic gating and image intensification techniques.
