Service Water System Inspection Locator (SWSIL)

Inspection and maintenance of a service water system is a key to reliable system operation. As emphasized by NRC Generic Letter 89-13, service water system reliability in nuclear plants must by assured since the SWS may support safety related equipment The diversity of design, water chemistry, and operating regimens, coupled with the tremendous size of these systems (literally miles of piping and hundreds of heat exchangers) makes the selection of locations to be inspected a difficult chore. In cooperation with the Electric Power Research Institute (EPRI) and the New York Power Authority (NYPA), a Service Water System Inspection Locator (SWSIL) has been developed to explore the feasibility of using an expert system to evaluate the corrosion susceptibility of the thousands of locations and components associated with nuclear service water systems (SWS). Such an expert system provides utilities with a method for planning and prioritizing inspections. SWSIL, Version 1.0, has been applied to the emergency diesel generator service water cooling loop of the emergency service water (ESW) system of the James A. FitzPatrick plant. The feasibility demonstration described in this report provided a framework for applying SWSIL to a system of any size. The demonstration also showed that refinement of the plant data input interface and flow modeling are required. Applicability of SWSIL in its current configuration to large systems is limited and awaits these improvements.
