A fire at the Savannah River National Laboratory in South Carolina triggered an emergency declaration on Wednesday after an unfiltered, ground-level radiological release. The blaze was contained to a single room, and no contamination has been reported outside the affected facility.
Fire and emergency response
The site area emergency was declared at 5:39 pm after flames broke out in one room at the laboratory near Aiken. The Savannah River Site (SRS) posted an update on its official X page confirming the fire had been extinguished.
Officials told local broadcaster WRDW that there was “an unfiltered, ground-level radiological release,” emphasizing that no contamination was reported outside the impacted facility and no consequences have been indicated beyond the site's boundaries.
Restrictions and precautions
The Federal Aviation Administration imposed a flight restriction, citing a US government “nuclear incident” at the location. SRS stated that barricades at site entrances had been closed to incoming traffic, with rail, river, and air traffic in the vicinity also restricted.
“As a precaution, barricades at site entrances have been closed to incoming traffic. Rail, river, and air traffic in the vicinity of SRS is also being restricted. SRS officials are directing response efforts and have notified the appropriate state and local government agencies,” the statement added.
Residents were advised to tune in to local radio and TV stations for any actions state officials may announce. Staff in Area A, the laboratory section, sheltered in place behind barricades before being permitted to depart, though no entry was allowed.
Site background and status
The origin of the blaze, the type and quantity of substance discharged, and whether any injuries occurred remain undisclosed. The emergency declaration, the second-highest of three categories at the site, indicates “something more serious has occurred,” according to the site's community preparedness information. It ended Wednesday night after the fire was extinguished.
The SRS spans approximately 310 square miles along the South Carolina-Georgia border. Established in the 1950s, it produced plutonium and tritium for atomic weapons during the Cold War and now focuses on nuclear materials management, environmental remediation, and research.
