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 technology of the free electron maser (FEM) has advanced to where it now is an attractive source for electron cyclotron heating (ECH) in tokamaks at reasonable cost. FEM's are capable of producing CW power at frequencies 50–400 GHz with power levels up to 5 MW/module. They can operate as a high gain (30–40 db), wide band amplifier (Δf/f = 5–10%). Such systems incorporate high quality (low emittance and energy spread) electron beams of moderate current which are electrostatically accelerated before passing through a large amplitude wiggler. Highly efficient recovery of the energy from the “spent” beam is feasible and enhances the total FEM system energy to nearly 50% even though the beam extraction efficiency is rather modest.
