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.

Established in 1946, Major Tool & Machine (MTM) is a contract manufacturer in Indianapolis, Indiana, just minutes from the ANS annual meeting, that provides manufacturing solutions for our customer’s most complex needs. MTM specializes in large CNC milling and turning machining, manual and robotic welding, engineering, program management, inspection, and assembly services. Major Tool & Machine proudly serves a variety of industries, including nuclear, and specializes in many areas of the nuclear fuel cycle:
MTM offers turning, milling, high-speed machining, flexible manufacturing, welding, semi and automated robotic welding, fabrication, and material processing. You really have to see the facilities to fully appreciate the vast capabilities that are available. MTM was acquired in September 2021 by Precinmac, a family of precision machining and fabrication companies, and shares a sister company, Petersen Inc., which also heavily supports the nuclear industry.
Attire should be business casual/comfortable, closed-toed shoes are required. Safety glasses will also be required but will be provided to attendees.
