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 new mixed fossil/nuclear energy system for the production of electricity from coal is presented, in which the process heat of a high-temperature reactor is used to produce a synthesis gas in a fluidized bed, via a water/gas reaction. A gas turbine, or alternatively a high-temperature solid oxide fuel cell, is used to produce electricity in a combined steam cycle as well as pure CO2, which is condensed and disposed in the deep ocean. The overall efficiency of such a system is higher than that of the classical CO2 recovery system, particularly for a high-temperature solid oxide fuel cell. Thus, the recovery and disposal of CO2 from an energy system, based mainly on fossil fuels, seem to be no longer utopian.
