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 critical evaluation was made of the experimental data regarding the rate of tritiated water formation. The evaluation tested the validity of the rate expression shown in Eq. 1. The experimental data does not appear to support the use of this rate expression for predicting tritiated water formation rates over wide ranges of initial tritium concentrations and large spans of reaction times. Modeling results are discussed which indicate the complexity of the tritiated water formation mechanism. The simplicity of Eq. 1 can not express the effects of the mechanistic complexity on the rate.
