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.

To investigate the feasibility of applying a porta-ble neutron generator for neutron radiography (NR), an underwater NR facility was designed and constructed in the water pool in a hot laboratory. By using the system, including neutron converters and films, it was possible to obtain NR images within ∼10 min. Various characteristic tests and photography by both emulsion and tracketch methods were carried out for various objects containing irradiated nuclear fuel samples. Some combinations of the converter and x-ray films, such as gadolinium foil/Type AA, were found to be suitable for NR in this case, but the much more sensitive converter NE426 was able to reduce the exposure time considerably. The strongly irradiated nuclear fuel samples were successfully photographed by CA-8015 track-etch films with a 10BN converter.
