AIKEN, S.C. (AP) - South Carolina's former nuclear weapons complex is again offering the public a chance to tour the facility.
Starting Monday, people can sign up for the Savannah River Site tours that begin in January. Organizers say that they are offering 22 free driving tours next year, with about 1,100 openings.
Guests will be given an overview and safety briefing before the four-hour tour. Officials say visitors can learn about how the U.S. Department of Energy has used the site and what happens there now.
Participants must be U.S. citizens who are at least 18 years old.
The 310-square-mile site once produced plutonium and tritium for atomic bombs. Work there is now focused mostly on research and cleaning up areas of the site contaminated during weapons production.
