Shippingport Atomic Power Station decommissioning, Shippingport, PA. (c.1986)

DOE description:
"The Shippingport Atomic Power Station was constructed during the mid-1950s to develop and demonstrate Pressurized Water Reactor (PWR) tchnology and to generate electricity. During its operation, the reactor, which produced 6.35 billion kilowatt-hours of electricity was fueled with three different types of cores, the last being a Light Water Breeder core. The station was shut down in October of 1982, after completion of the breeder demonstration program, and is to be decommissioned. All fluids, piping, equipment, components, structures and waste having radioactivity levels greater than those permitted for unrestricted use of the property are to be removed from the site. The 25-foot high, 10½-foot diameter reactor vessel is to be encased in a shielding material and moved, in one piece, to the Hanford site for permanent disposal. Plant disassembly is expected to demonstrate the safe and economical decommissioning of a commercial power reactor."
 
"This structure was constructed of reinforced concrete. A large ram-hoe and headache ball was used to demolish the structure."
