Conference ·
OSTI ID:5194725
The Shippingport Station Decommissioning Project (SSDP) is a US Department of Energy (DOE) sponsored project to dismantle the Shippingport Atomic Power Station (SAPS) and return the government-leased property in a radiologically safe condition to its owner, Duquesne Light Company. One key feature of the project includes the removal of the RPV/NST package from its existing location at SAPS and its transportation by barge to the government-owned Hanford Reservation in Richland, Washington. The package, which consists of the RPV, its non-fuel-bearing internals, and the integral Neutron Shield Tank (NST), will be prepared as a monolithic metal/concrete package for shipment. The package which is about 5.1 meters (18') in diameter by 12 meters (41') in length with a gross weight of about 907 metric tons (1000 tons), will contain approximately 16,000 curies of radioactivity, and have a surface contact radiation exposure rate of approximately 2 mrem/hour. The package is currently located approximately 19 meters (63') below grade in the Reactor Enclosure. 7 refs., 1 fig.
