A fire broke out at the Savannah River National Laboratory on Wednesday, October 28, 2026, in South Carolina. At 5:39 a.m.local time (2139 GMT) the Department of Energy’s Savannah River Site declared an emergency, shutting down traffic ramps and temporarily restricting rail, river, and air traffic near the facility.
Employees who were not directly involved in firefighting or shutdown operations were moved to sheltered areas as a precaution. The lab’s social-media statement explained that the blaze had been contained and no contamination had spread beyond the building.
"The fire has since been extinguished. No contamination has been reported outside the affected facility," the SRS said.
The Savannah River Site, built in the 1950s to produce tritium and plutonium for U.S. weapons, is now used for environmental stewardship, waste management and the disposition of nuclear materials. Despite the wide use, the emergency was resolved quickly; by 9:45 p.m. local time (0145 GMT Thursday) the emergency declaration was terminated and normal operations resumed.
Officials emphasized that the quick response prevented any environmental exposure and that the site’s safety systems effectively contained the incident.
