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 detailed cost study of the ESPRESSO blanket concept for the Tandem Mirror Fusion Reactor has been performed to complement the thermal-hydraulic parametric study of Reference 1. A computer code was developed to size the magnet, blanket and piping components and to evaluate the central cell contribution to the cost of electricity. The two most promising solid breeder/neutron multiplier configurations were studied: natural lithium oxide as the breeder with no multiplier (Case I), and 30% enriched gamma-lithium aluminate as the breeder with beryllium as the multiplier (Case IV). A design window was obtained for each case based on maximum material temperatures and spacing constraints. The minimum cost designs for Case I and Case IV correspond to 31 and 41 mills/kW-hr for the central cell contribution to the cost of electricity, and to optimum neutron wall loadings of 2.3 and 3.4 MW/m2, respectively.
