Fire at South Carolina nuclear lab triggers brief emergency

The Savannah River National Laboratory in South Carolina declared a Site Area Emergency on Wednesday evening following a fire in one of its laboratories. The incident began at 5:39 pm local time, prompting officials to initiate protective protocols and restrict movement around the facility. By 9:45 pm the same evening, the emergency status had been lifted after firefighters extinguished the blaze and confirmed no radioactive contamination.

One employee sustained minor injuries and was transported to a hospital. A spokesperson for the US Department of Energy confirmed the injury and stated that no radiological contamination was reported. The department noted that safety remains a priority for workers, the public, and the environment.

Following the extinguishing of the fire, officials removed temporary barricades from Highway 125 and the site’s entrances. Traffic returned to normal flow. Earlier in the response, restrictions were placed on rail, river, and air traffic near the location. State and local authorities were notified, and residents were advised to monitor local radio and television for updates.

The Savannah River Site issued a notification indicating that there are currently no operational emergencies or scheduled delays. Workers who were due to start their shifts were instructed to report as usual. Employees who had been told to shelter in place received the all-clear to resume normal duties. Other staff members were instructed to return to work on Thursday, October 29.

The facility is a component of the US nuclear weapons complex and has supported the country’s strategic deterrence program for more than 75 years. Built in the 1950s, the site originally included five reactors constructed to produce tritium and plutonium-239 for nuclear weapons. It also houses two chemical separation plants. The site currently manages nuclear materials and radioactive waste, with ongoing clean-up operations designed to protect the surrounding environment.
