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 swelling of mixed oxide in fuel elements irradiated within the irradiation program of the German Fast Breeder Project was determined. In fuel pins with a burnup-independent high power level, a constant swelling rate of 0.5% per percent burnup was found at burnups above 4%. It is concluded that this swelling rate is induced by solid fission products. The volume-averaged swelling due to fission gases seems to be saturated at a value of ∼6%.
