Hermes 2 Demonstration Plant

under construction

Hermes 2 is Kairos Power's first commercial-scale advanced nuclear reactor and the first power-producing Generation IV reactor to receive a construction permit from the US Nuclear Regulatory Commission. The 50-MW facility will supply clean electricity to the Tennessee Valley Authority grid, supporting decarbonization of Google data centres in Tennessee and Alabama. It builds on lessons from the Hermes 1 Low-Power Demonstration Reactor and uses fluoride salt-cooled high-temperature reactor technology with Triso coated particle fuel and molten fluoride salt coolant.
