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.

In the nuclear fuel reprocessing plant, dissolver off-gas (DOG) is supposed to include nitrogen oxides (NOX) during the operation. An adsorption process by mineral zeolite has been studied for DOG treatment that follows a dehydration and iodine removal process. According to the results, the characteristics of the mineral zeolite hydrogenated by 1 N HCl are very favorable for this purpose. As for the actual operation, a small fraction of iodine is supposed to penetrate the I2 removal process to the NOX adsorption process. No degradation has been observed for the NOX adsorption of mineral zeolite by the presence of I2.
