This paper considers the use of on-line structural health monitoring in advanced nuclearpower systems such as IRIS. The motivation for the on-line health monitoring is to prevent routinemaintenance from interrupting long-term continuous reactor operation. However, the outcome of theon-line monitoring implementation has a broader impact, and amounts to a paradigm shift inmaintenance strategy from outage-based maintenance to continuous real-time monitoring ofoperational and structural integrity. Indeed, on-line health monitoring data will provide a foundationfor diagnostics and prognostics (i.e., predictive) capabilities that will detect component degradationprior to failure, thus allowing for proactive rather than reactive maintenance strategies. Specifically,this paper briefly reports on our studies on (1) on-line monitoring strategy and its benefits, (2)candidate reactor components where on-line monitoring provides maximum benefits, (3) applicableon-line NDE sensor methodologies and conceptual sensor designs, and (4) model-based sensorperformance estimations
