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 simple fuel performance code, SESAME, has been developed to analyze the steady-state irradiation behavior of metallic fuels. Important characteristics of metallic fuels such as fission product gas release, swelling, material redistribution, bonding sodium infiltration, and axial elongation are studied. Simple models have been developed for the SESAME code, which have been found to be successful in predicting irradiation data and useful in investigating the basic mechanisms that contribute to these particular irradiation behaviors of metallic fuels.
