GTS Duratek, a Columbia hazardous-waste-disposal company, said yesterday that it and several partners have reached agreement with the Department of Energy on a contract worth about $6.9 billion for cleanup at a federal storage site for radioactive waste.
GTS Duratek and its lead partner, BNFL Inc. of Britain, will immobilize up to a quarter of the radioactive materials in 54 million gallons of waste at the federal Hanford Site near Richland, Wash.
The government stores radioactive byproducts and nuclear waste in 177 underground tanks at Hanford.
The work is to be completed by 2018. GTS Duratek treats low-level nuclear waste through vitrification, in which the dangerous material is melted into inert glass.
