The Department of Energy’s Office of Environmental Management recently announced that, with the help of contractor Central Plateau Cleanup Company, it has completed the safe demolition of the 175-foot-tall exhaust stack of the K West reactor at the Hanford Site in Washington state.

DGR Grant Construction will construct a safe-storage enclosure over the K East Reactor building at the Department of Energy’s Hanford Site in Washington state. Two construction subcontracts, worth about $9.5 million, were awarded to the Richland, Wash.–based company by Central Plateau Cleanup Company, the DOE’s Richland Operations Office site cleanup contractor.
