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.

Prediction of the room-temperature fatigue life of Type-347 stainless steel, irradiated to 5.5 × 1021 and 11 × 1021 n/cm2, was attempted from tensile tests and the use of Manson's relationship. It was found that the total strain vs cycles-to-failure for irradiated Type-347 stainless steel can be predicted reasonably well for total strains of 1 to 2% at both levels of irradiation. However, the predicted fatigue lives were conservative for total strains that are <1% for material irradiated to a fast fluence of 11 × 1021 n/cm2. Not enough experimental data points were available to correlate the measured fatigue life with predicted fatigue life at total strains of <1% for stainless steel irradiated to a fast fluence of 5.5 × 1021 n/cm2.
