Department of Energy Savannah River Site
For nearly 60 years, the federal reservation known as the Savannah River Site has proudly served the nation.
Born in the midst of Cold War secrecy, SRS has always operated safely and efficiently to execute its missions. During the Cold War, it produced one-third of the nation's weapons-grade plutonium and all of the nation's tritium - both integral components of nuclear weapons.
When the Cold War ended, the United States no longer needed the amounts of new nuclear materials as before. There was more than enough plutonium to supply the nation's reduced nuclear arsenal. Tritium, which is a gas that decays much more rapidly than plutonium, had to be replenished regularly, but this could be accomplished for years by recycling and repurifying existing tritium.
