Security alert at US nuclear site Savannah River Lockdown at US nuclear site Savannah River comes to end
(31 minutes later)
A nuclear processing site in South Carolina has been locked down because of a security alert. A lockdown caused by a security alert at a nuclear processing site in South Carolina has ended, officials say.
In a statement on the Savannah River facility's Facebook page, officials said an emergency response was under way and the site closed to traffic. The Savannah River facility was closed after a bomb-sniffing dog detected possible explosive residue on a truck.
According to an internal memo seen by Reuters news agency, a threat has been identified at an area used for uranium enrichment. But a US official told Reuters news agency that the site had since been deemed safe, though they were still investigating the delivery vehicle.
A news release from the site in Aiken did not say what kind of alert it was. The facility, which is owned by the US Department of Energy, purifies highly enriched uranium.
But it said there was no indication it was having any effects beyond the site's boundaries. Earlier, on its Facebook page, officials said an emergency response was under way and the site was closed to traffic.
