Development of a Reactor Coolant Pump Monitoring and Diagnostic System. Topical Report: System Development and Installation, July 1980-May 1984

摘要

Reactor coolant (RC) pump seal failures have resulted in the excessive leakage of primary coolant into reactor containment buildings. In some cases, high levels of airborne activity and surface contamination following these failures have necessitate extensive cleanup efforts and personnel radiation exposure. The cost of reduced plant availability and increases in radiation exposure have been serious concerns to reactor vendors and the utilities. The RC pump monitoring and diagnostic system has been developed, designed, and installed at Toledo Edison's Davis-Besse Nuclear Power Station to examine the relationships between seal failures and the environment in which the pumps operate. The data collection task, started recently, will closely examine the rotordynamic aspects of pump behavior and the operational environment that is controlled by the plant operator to characterize the effects upon pump seal performance. 7 refs., 6 figs.
