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 thermal conductivity of loose, pyrolytic carbon-coated fuel particles in helium was studied at temperatures from 1800 to 2700°F using a convenient comparative technique. The conductivities of coated particles with both 150- and 795-µm overall diameters were shown to rise and then remain constant as the helium pressure was increased to 4 atm. Measurements using particles with various coating thicknesses and structures indicated that bed conductivity was relatively insensitive to the properties of the coating.
