[en] Project plans are the primary documentation used by the DOE Decision Authority to identify the Major System Acquisition Process - Key Decision Points. For the Shippingport Station Decommissioning Project (SSDP) the four key decision points are: approve the mission need, project objective, and the initiation of project activity; approve the selection of the SSDP decommissioning mode; approve the initiation of SSDP decommissioning operations; and approve the release of the Shippingport Station site as safe from a radiation standpoint. The purpose of the SSDP is to place the Shippingport Atomic Power Station in a long-term radiologically safe condition following defueling of the reactor, to perform decommissioning in such a manner as to demonstrate to the nuclear industry the application of decommissioning procedures to a large nuclear power plant, and to provide useful planning data for future decommissioning projects

[en] An outline of the Shipping-port Station Decommissioning Project is presented. The objectives of the decommissioning operations stage are detailed and technical features of the project are discussed. The estimated costs for the total decommissioning project are given. (U.K.)

[en] Decommissioning of the Shippingport nuclear power station commences in September 1985 and is due for completion in April 1990. After 25 years of operation as a pioneering power plant, Shippingport will now become the most significant reactor decommissioning operation so far anywhere in the world. It is close enough to a full scale commercial nuclear power station to give hard data on costs and relevant experience on the practical implications of decommissioning. The operating history of Shippingport is summarised, then the decommissioning programme is tabulated. The two aims of the decommissioning are; no primary system decontamination and one-piece removal of the reactor pressure vessel. These are discussed. The estimated cost is given. (U.K.)

[en] The overall objective of the project is to place Shippingport in a long term radiologically safe condition following termination of operations and to perform the decommissioning in such a manner so as to provide engineering, technology and cost information for future projects. The Decommissioning Assessment, Environmental Assessment, and a draft outline for the EIS have been completed. The results of the assessments are summarized. In addition, the management of the Shippingport decommissioning project is discussed

[en] Shippingport was shut down in October 1982. Defueling operations were complete September 1984. The decommissioning project consists of 2 phases and will be completed in April 1990. This overview discusses the schedule, technical statistics, organization, operations, scope of activity specifications, final site configuration, radiological condition, and cost summary

[en] The Shippingport Station Decommissioning Project (SSDP) is the first commercial size nuclear power plant to undergo decommissioning in the United States. One of the objectives in decommissioning the plant is to demonstrate the technology used and thoroughly document the results for dissemination to utilities, government entities, the nuclear industry, and the decommissioning community. DOE has established a Technology Transfer Program to assure that useful information compiled on the project, such as management techniques, radiological controls, decommissioning methods, lessons learned and other special studies and tests, expected to be of interest to the industry, is adequately documented and available to outside parties or participants. The Shippingport decommissioning experience will create a significant data base for the nuclear utility industry in future decommissioning of commercial nuclear power generating facilities

[en] The Shippingport Atomic Power Station was operated with the Light Water Breeder Reactor (LWBR) core primarily at high power levels (base load) until September 12, 1980 when a planned semi-annual shutdown for testing and maintenance began. During this operating period, the originally planned core lifetime of 18,000 equivalent full powers (EFPH) of operation was achieved on August 31, 1980. Station startup commenced on November 5, 1980. The Station was shutdown on November 13, 1980, and while in this plant condition, a primary coolant leak was discovered on the 1'' bonnet vent line of a 1C loop manual isolation valve. Repairs were completed and satisfactorily tested. The Station returned to power operation on November 26, 1980. Power Operation continued through the end of the report period

[en] The Project Scheduling system being employed by the Decommissioning Operations Contractor at the Shippingport Station Decommissioning Project (SSDP) is described. Results from the planning system show that the project continues to achieve its cost and schedule goals. Initial technical, cost, and schedule baseline guidance was issued for the project in a Decommissioning Plan in September 1983. An integrated cost and schedule control system (C/SCS) which uses the concept of earned value for measurement of performance was instituted in accordance with DOE orders. The schedule and cost variances generated by the C/SCS system are used to confirm the management's assessment of project status. The types of schedules and tools used on the SSDP project to plan and monitor the work are described, and factors that are unique to a decommissioning project that make scheduling critical to the achievement of the project's goals are identified

[en] The project assigned by the Department of Energy to General Electric for the complete dismantling of the 60MW pioneer Shippingport nuclear power station which was operational from 1957 to 1983 is described. The company sees one of its main aims as the gathering of practical experience for future decommissioning of worn-out nuclear power stations. New handling techniques for radioactive material are to be tried, and parts of the light-water reactor broken up under water. The work is expected to take four and a half years. (M.B.D.)

[en] The Shippingport Atomic Power Station consists of the nuclear steam supply system and associated radioactive waste processing systems, which are owned by the US Department of Energy (DOE), and the turbine generator and balance of plant, which is owned by the Duquesne Light Company (DLC). The station is located at Shippingport, Pennsylvania on seven acres of land leased by the US DOE from the Duquesne Light Company. The Shippingport Station Decommissioning Project (SSDP) is being managed by the General Electric Company for the US DOE. The lessons learned from a management perspective during the performance of the SSDP are described. The lessons learned are presented in a chronological sequence during the life of the project up to the present time. The careful analysis of the lessons learned at SSDP and the implementation of corresponding actions have contributed toward improving the effectiveness of the SSDP as time progresses. The lessons learned should be helpful in planning future decommissioning projects
