The Nuclear Regulatory Commission announced yesterday that it has directed staff to issue construction permits to Kairos Power for the company's proposed Hermes 2 nonpower test reactor facility to be built at the Heritage Center Industrial Park in Oak Ridge, Tenn. The permits authorize Kairos to build a facility with two 35-MWt test reactors that would use molten salt to cool the reactor cores.

Nuclear Regulatory Commission staff has completed its final safety evaluation for Kairos Power’s application to build its Hermes 2 molten salt–cooled reactor test facility in Oak Ridge, Tenn., the agency announced July 22. Earlier, and independently, the NRC’s Advisory Committee on Reactor Safeguards (ACRS) reviewed safety-related aspects of the Kairos application and provided its review to the Commission on July 17. The evaluation concluded that there are no safety aspects that would preclude issuing a construction permit for the facility, but that can’t happen until the NRC staff issues its final environmental assessment later this summer and the Commission assesses the staff’s work (under newly streamlined procedures for mandatory hearings) this fall before voting on whether to authorize a construction permit.
