The Department of Energy’s Savannah River Site is now allowing traffic onto the property after locking down for several hours Monday.
Officials with the former nuclear warheads site halted all traffic after they said electronic canine scans and drug-sniffing dogs indicated “a possibility of explosive residue” on a delivery truck. SRS officials said later Monday evening that a follow-up found no residue.
Law enforcement agencies from South Carolina and Georgia were called and are on the scene to assist Centerra, the site’s security contractor.
The SRS statement said there is “no indication of a consequence beyond the Savannah River Site boundaries.”
The Savannah River Site is a nuclear reservation located on land in Aiken, Allendale and Barnwell Counties adjacent to the Savannah River. The site was built during the 1950s to refine nuclear materials for deployment in nuclear weapons. It covers 310 square miles and is owned by the U.S. Department of Energy.
Although the Energy Department oversees the site, its day-to-day operations are mostly run by contractors cleaning up radioactive and other hazardous waste.
