Good performance is essential for boiling water reactor (BWR) plant life extension (PLEX). Economic evaluations show that the benefits attributable to extended service of a typical BWR depend on maintaining a high capacity factor. Plant reliability as measured by forced outage rate must also be managed to recover the investments made for longevity. In addition to economic factors, technical evaluations suggest that sustained high availability is a reliable indicator of sound equipment and operating procedures, both necessary elements for long BWR life. Many performance improvements that are made to reach short- or medium-term goals also enhance longevity. Examples include hydrogen water chemistry to avoid stress corrosion cracking (SCC), predictive maintenance, enhanced feedwater control, and scram reductions. From a regulatory perspective, the good performance of a BWR usually implies a high safety margin. This paper illustrated the relation between performance and longevity for BWR plants in the economic, technical, and regulatory areas.
