Workers demolishing an old power house Friday at the Hanford Nuclear Reservation used explosives to bring down five struct-ures, including a pair of 250-foot exhaust chimneys.
Controlled blasts also took down the power house’s two 90-foot air-filter structures and a 140-foot water tower, the Tri-City Herald reported.
The power house was built in 1943 as part of the Manhattan Project to build the first atomic bomb. It burned coal to provide steam for chemical processes used to produce pluton- ium and to heat nearby offices.
The power house was taken out of service in 1992, although the water tower was used until 1998.
