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.

Production of 18F, a positron emitter, with fast protons from D-3He fusion reactions and oxygen (18O) impurities in a large tokamak is studied numerically. A high-energy deuterium beam is used for proton production enhancement. The yield of 18F is found to be optimized in a somewhat dirty plasma with an effective ionic charge number of Zeff ∼ 5 and doubled by the inclusion of the possible resonance in the 18O(p,n)18F reaction. The yield in the deuterium beam-injected 3He plasma is 1000 times larger than by standard methods using a cyclotron. A comparison is also made with the yield in an advanced plasma regime.
