The extension, announced Friday, will bring the total value of the company’s contract to about $8 billion, according to company officials. The extension will run from Aug. 1, 2013, to September 2016.
The company was awarded a five-year contract in January 2008 over a competing proposal from Savannah River Alliance, composed of incumbents of Washington Savannah River Co., which had managed the site since 1989.
Savannah River Alliance appealed the award to its competitor on grounds that its rival’s price was higher and that conflicts of interest existed within its management, but the decision was upheld after scrutiny from the Government Accountability
Activities under way at the site include continuing nuclear cleanup, long-term nuclear materials management and support to the nuclear weapons stockpile and nonproliferation requirements.
