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.

A preferential dissolution by a factor of 1.1 to ∼10 of the radiogenic nuclides 234U, 230Th, and 228Th relative to their corresponding structurally incorporated isotopes 238U and 232Th has been observed upon leaching of natural monazite samples in a bicarbonate-carbonate solution. This isotopic fractionation may be attributed to radiation damage caused by alpha-recoil atoms. The observations have implications for the storage of crystalline nuclear waste forms in deep geological formations. The damage may endanger the integrity of any crystalline phase that contains alpha-emitting nuclides in groundwater environments. It is inferred that in monazite-like phases the overall alpha-recoil damage may increase nearly in proportion to the alpha-particle dose over the long time range (∼105 yr) required for the isolation of actinide wastes.
