Probably the most critical aspect of nuclear power plant operation is plant maintenance. The ideal situation, from the plant maintenance perspective, would be to have an expert in every phase of plant design and operation constantly available. There are alternatives, however, to the human expert for some aspects of plant maintenance. This paper discusses a microcomputer-based expert system designed to assist nuclear power plant maintenance activities. Impell Corporation's PbSHIELDING system, which is currently in use at nuclear power plants throughout the country, including three Commonwealth Edison plants, has been developed for the on-site evaluation of temporary lead shielding placement on piping systems. This paper focuses on the benefits gained from the use of computerized expert systems such as PbSHIELDING for plant operations and maintenance activities. Time and cost savings resulting from the use of such an expert system as well as benefits seen from reduced radiation exposure due to increased allowable lead shielding quantities are discussed in detail. This cost/benefit study will be based on actual evaluation data gathered from current users of the PbSHIELDING expert system.
