The United Kingdom’s Department of Energy Security and Net Zero has signed off on Westinghouse’s AP300 small modular reactor earlier this month.

The Tennessee Valley Authority this week discussed the potential for new nuclear technology at its sites during its second-quarter earnings call.
TVA and GE Hitachi signed an agreement in 2022 to develop and deploy a BWRX-300 small modular reactor at the Clinch River site near Oak Ridge, Tenn.

Earlier today, on a site in Oak Ridge, Tenn., that was formerly home to the K-33 Gaseous Diffusion Plant, Kairos Power marked the start of construction on its low-power demonstration reactor. Named Hermes, the 35-MWt test reactor claims status as the first Gen IV reactor to be approved for construction by the Nuclear Regulatory Commission and the first non–light water reactor to be permitted in the United States in more than 50 years.

Eielson Air Force Base in central Alaska has been the preferred location to demonstrate the benefits of microreactors to the U.S. Air Force—and by extension the Defense Department—since 2018. Now, a protracted solicitation process is nearing an end, and the Air Force and the Defense Logistics Agency Energy (DLA Energy) expect to announce a final procurement decision by the end of the summer—or about one year after Oklo Inc. announced that it had been tentatively selected to supply a microreactor under a 30-year power purchase agreement.

A public hearing in Kemmerer, Wyo., drew dozens of comments and questions about TerraPower’s plans to build the Natrium nuclear reactor demonstration project in the coming years.

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.

Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

Aalo reported last week that it has submitted a regulatory engagement plan to the Nuclear Regulatory Commission in “a huge step forward in getting regulatory approval for our Aalo-1 reactor.”
