The federal government has picked up the tab for the security for the Savannah River Site for the next decade. The U.S. Department of Energy has signed a nearly $1 billion contract with an international private security company to continue to serve as the security arm to protect the Savannah River Site. Officials announced Thursday that the D.O.E. had hired Wackenhut Services for $989 million over the next 10 years. The company based in Palm Beach, Florida currently provides security at the S-R-S site near Aiken. The contract includes protecting nuclear material and facilities from sabotage.
