Kairos Power has received the go-ahead from the Nuclear Regulatory Commission to build its Hermes demonstration reactor at the Heritage Industrial Park in Oak Ridge, Tenn., making it the first non–light water reactor approved for construction in the United States in more than 50 years.

The Nuclear Regulatory Commission staff has completed its final environmental impact statement (FEIS) for Kairos Power’s application to build the Hermes demonstration reactor in Oak Ridge, Tenn., and is advising that the construction permit (CP) be issued.

“After weighing the environmental, economic, technical, and other benefits against environmental and other costs, and considering reasonable alternatives, the NRC staff recommends, unless safety issues mandate otherwise, that the NRC issue the CP to Kairos,” the FEIS states.

Having completed its review of the construction permit application for Kairos Power’s Hermes test reactor early last month, the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) recently submitted its conclusions to the agency, recommending approval.

The Nuclear Regulatory Commission is requesting public input on environmental issues that the agency should ponder as it reviews Kairos Power’s application for a construction permit to build the Hermes low-power demonstration reactor at the East Tennessee Technology Park in Oak Ridge, Tenn.

In a notice published in the February 18 Federal Register, the NRC says it will conduct a scoping process to gather information necessary to prepare an environmental impact statement (EIS) for the proposed project.
