The Nuclear Regulatory Commission has authorized Southern Nuclear Operating Company to begin loading fuel into Unit 4 at the Vogtle nuclear expansion site near Waynesboro, Ga., making the unit the second reactor to reach this milestone in the agency’s combined license process—a little less than one year after Vogtle-3. (Prior to 1989, reactors were licensed under a two-step process, requiring both a construction permit and an operating license.)

The Nuclear Regulatory Commission staff has completed its final safety evaluation for Kairos Power’s application to build its Hermes advanced test reactor at a site in Oak Ridge, Tenn., the agency announced recently. The evaluation found no safety aspects precluding issuance of a construction permit for the proposed reactor.

The Nuclear Regulatory Commission has authorized the restart of a test reactor at the National Institute of Standards and Technology, in Gaithersburg, Md. The reactor was shut down in February 2021 when a fuel element became damaged during startup and approach to full power. The incident violated the NRC’s fuel cladding temperature safety limit, although public health and safety were not affected, according to the agency.

The reactor is located at NIST’s Center for Neutron Research.

The Nuclear Regulatory Commission has authorized Vogtle plant operator Southern Nuclear to load fuel and begin operation at Unit 3—the first reactor to reach this point in the agency’s combined license process. (Prior to 1989, reactors were licensed under a two-step process, requiring both a construction permit and an operating license.)
