RELIABILITY STUDY. EQUIPMENT AND COMPONENTS IN NUCLEAR POWER PLANTS (A FINAL ENGINEERING REPORT). Project No. 6185
The operating experience at five nuclear power plants is reviewed and analyzed. The various events recorded are categorized according to the nature and severity of the event and by the type of equipment or component involved. The problems encountered are discussed by type category, and certain general and specific recommendations concerning reliability improvement are made. More than 1800 incidents are reviewed. 0f these, nearly 300 caused unscheduled loss of load by the plant involved. Most of these unscheduled load-loss failures and many other occurrences are discussed in the report. The five nuclear power plants included in the study are as follows: Experimental Boiling Water Reactor (EBWR), Shippingport Atomic Power Station, Stationary Medium Power Plant No. 1 (SM-1), Stationary Low Power Plant No. 1 (SL-1), and Vallecitos Boiling Water Reactor (VBWR). The most significant area of trouble has been instrumentation and control, particularly in the nuclear portion. Among more conventional apparaths, the turbine-generator, piping, electrical auxiliary equipment, instruments, controls, and valves accounted for many maintenance problems and failures. These problems are discussed, and corrective or preventive measures are recommended. An over-all program aimed at improving the reliability of nuclear power plants is presented in terms of responsibilities of the sponsoring agency, administrator, designer, engineer, manufacturers, erectors, and operators.
