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.

At the LOTUS facility, an extremely efficient online detector system, based on the detection of the charged particles associated with the 6Li(n, α)t reaction, has been designed, fabricated, and tested. The system offers an interesting possibility for directly measuring the tritium production rate (TPR) at any experimental site. The charged particles emitted in opposite directions can be detected by a double parallel plate ionization chamber (DIC) configuration. The real events are identified by employing a coincidence circuit. The complete fabrication details, testing under different conditions, measurement of TPR, and its comparison with the liquid-scintillation method (LSM) are detailed. The DIC response to thermal neutrons agrees well with the theoretical calculations. Also, the detector system is insensitive to a contact gamma dose rate of 1.3 rem/h. The direct TPR measurements and the salient feature of higher efficiency in comparison with the LSM are demonstrated. The TPR determined by both methods are in excellent agreement.
