Calvert Cliffs Nuclear Power Plant Life Cycle Management/License Renewal Program: Containment system component evaluation and program evaluation. Final report

Central to the Life Cycle Management (LCM) Program for the Calvert Cliffs Nuclear Power Plant (CCNPP) plant is its Integrated Plant Assessment (IPA) process. The IPA is a comprehensive, systematic evaluation of the effectiveness of age-related degradation management for the plant`s important systems, structures, and components. Components of structures identified as functionally important and within the scope of license renewal in the screening step are evaluated to determine if they are subject to aging management review. For those that are, further evaluations of aging issues are performed. At Calvert Cliffs, a detailed method and procedures for conducting component evaluations of structures have been developed and thoroughly tested. The development and application of these procedures have resolved problems that other utilities can avoid by adapting these methods to their own plants. The first report of this series contains an overview of the LCM and IPA process. This report, which is another in the series of EPRI reports on the Calvert Cliffs IPA process, describes the methodology for performing component and program evaluations for structures.
