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 basic neutron physics investigations and the conceptual design of a cylindrical fast subcritical facility for investigating the properties of fast reactor blankets have been completed. The Department of Nuclear Engineering at Purdue University plans to construct this facility to enable students to carry out studies in fast reactor blankets and reflectors. Fast neutron flux spectra in this facility can be made very similar to the spectra anticipated in the blanket of either a typical large liquid-metal or gas-cooled fast breeder reactor. Fast neutron spectra, spatial flux distributions, plutonium production rates, neutron transmission, and other physics parameters of typical fast reactor blanket designs can be investigated with this facility. The results can be used to refine the analysis and to improve the designs of blankets and structures outside the blankets in future fast breeder reactors.
