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 conceptual design for a demountable TF coil is presented. The work is being pursued as part of an ongoing study of the Resistive Magnet Commercial Tokamak Reactor (RCTR) at MIT. The RCTR is an attractive commercial tokamak option which utilizes resistive magnets characterized by low stresses, low current density and moderate dissipated power. The demountable coil design for RCTR presented here features a relatively simple configuration with a large cross-section available for current transfer in the joint. The concept allows for complete removal of the TF coil with the blanket/first wall in place. Analysis also indicates significant advantages for the overall RCTR concept due to the possibility of placement of the EF and OH coils within the TF bore. These advantages include reduced PF coil size, dissipated power and TF overturning.
