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 aim of the MoI-7C in-pile local blockage experiments is to ascertain the consequences of local cooling disturbances in fuel subassemblies of liquid-metal fast breeder reactors. The experiments are carried out in the BR2 reactor at Mol/Belgium within the framework of a joint program of Kernforschungszentrum Karlsruhe and Studiecentrum voor Kernenergie/Centre d’Etude de VEnergie Nucleaire Mol. The last two experiments, Mol-7C/6 and 7, performed with the support of the Joint Research Centre Ispra in June 1988 and June 1989, respectively, are dealt with. The particular objective of these two tests is to investigate the consequences of local faults at high burnup and of blockages having contact with the subassembly wrapper tube. The test sections, the performance of the tests, and the results obtained are described. A preliminary interpretation is presented.
