Registration opens today for 2013 limited-availability public tours of the Savannah River Site.
The former Cold War site and laboratory complex will host 22 tours in 2013 for up to 1,100 people. Dates can be found here, with check-in for each tour beginning at 12:30 p.m. at the Center for Hydrogen Research in Aiken County, S.C. Each lasts about four hours and includes a demonstration at the Savannah River Ecology Laboratory, as well as a driving tour of the broader site.
The tours are free, but entry is restricted. To meet the site's security measures, participants must be adult U.S. citizens with two forms of ID available on the day of the tour.
