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.

Mound Laboratory is engaged in the recovery of tritium from waste materials generated at U.S. Atomic Energy Commission sites. A scrubber system for tritium removal has been designed and constructed at Mound Laboratory. The solutions to be analyzed are first boiled to dryness, and then baked 1 h at 500°C using H2SO4, HCl, or HNO3 as a carrier. The vapors from these solutions are passed through (a) a condenser to remove the bulk of the acid vapors, (b) an NaOH scrubber to remove acid fumes, (c) a mist eliminator to entrap fine mist particles, and (d) a molecular sieve bed to remove all traces of tritiated water. Environmental release is monitored by a Kanne electrometer system which measures the tritium content of the effluent. Use of the scrubber system yields residues with beta counts of <50 count/min with minimal release of tritium to the environment.
