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.

Intermunicipal collaboration in Greater Stockholm has been in operation for several years. In parallel with this collaboration, the Stockholm municipality and the Swedish State Power Board have entered into a collaboration on a nuclear combined district heating power station (NHPS) in Greater Stockholm. These municipalities and the state have jointly studied the future heat supply for Greater Stockholm and, in particular, the alternative based on heat from an NHPS. The investigations embrace an NHPS located in Greater Stockholm or at the Fors-mark nuclear plant (future units 3, 4, and/or 5) and various alternatives in which Greater Stockholm is supplied with heat by expansion of oil-fired plants. Different technical solutions were taken into account—type of turbine, method of transporting hot water, various outgoing temperatures, etc.—and the alternatives have been evaluated on different assumptions regarding fuel prices, investment costs, energy forecasts, and continued nuclear power expansion. A brief and general summary of the results is not possible. Nevertheless, taking into consideration the circumstances in the Greater Stockholm area, the investigations show that district heating and combined district heating power stations will expand in the region. If the relation of costs between nuclear and oil power continues, the investigations indicate lower total annual costs of oil-based systems than systems based on an NHPS. This conclusion is valid even if the oil price should increase ∼50%, provided that the number of nuclear power units is independent of whether or not they are used for district heating. But if the heat extracted from the station implies that the number of nuclear power units may be increased, the best nuclear alternative will be more economical than the best oil-fired alternative.
