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 large oil-free reciprocating pump was developed for high level tritium service. The pump is a water-cooled, single acting, four stage vertical piston vacuum pump. The characteristics of the pump were measured with H2, D2, He and N2 gases. Pumping speeds were approximately 180 M3/hr for these gases and almost constant above 10 torr of suction pressure., while it drastically dropped in the lower pressure region. The pump combination with a magnetic levitated turbomolecular pump worked well with N2, however He, D2 and H2 could not be pumped well due to poor matching of the characteristics of these pumps.
