The U.S. Energy Dept has awarded its last major revamped management contract this year at a U.S. nuclear cleanup megasite, selecting a URS Washington-division-led team for a $3.3-billion, six-year award to manage liquid wastes at the Savannah River Site in Aiken, S.C. It bested a competing bid from a team led by Parsons Corp. and including Fluor Corp., a Parsons spokeswoman confirms. The URS venture also includes Babcock & Wilcox, Bechtel National Inc., CH2M Hill Constructors Inc. and AREVA Federal Services LLC, the U.S. unit of the French nuclear technology firm. The award returns URS to a significant management role at the site, where DOE is in the process of consolidating its remaining nationwide stores of plutonium, once used to manufacture nuclear bombs. Earlier this year, URS lost a bid to secure a separate $4-billion Savannah River site-management contract to a Fluor-led team. Under its new contract, the URS team will manage closure of waste tanks and related production, disposal and tank-farm operations. Three other rescoped multibillion-dollar management contracts were awarded earlier this year at DOE’s Hanford nuclear weapon cleanup site in Washington state.
