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 2007 Recommendation of the International Commission on Radiological Protection [ICRP Publication 103, Elsevier (2007)] requires implementation of the concept of a dose constraint for members of the public living around nuclear facilities. Under the paradigm of regulatory science, the use of dose constraints is still highly debatable. This study determines whether a dose constraint is necessary for members of the public living near U.S. nuclear power plants (NPPs) using data from the years 2007 to 2009, which were provided by the Nuclear Regulatory Commission. As a result of analysis of exposure data, it is concluded that a dose constraint is not necessary for members of the public living around U.S. NPPs and that such a constraint may place an unnecessary regulatory burden on the licensees.
