"Demonstration of a Probabilistic Fracture Mechanics Framework for Predictive Maintenance Using an MSIV Example," Matthew Kirby

A predictive maintenance approach was used to extend the life of 17-4 PH steel main steam isolation valve (MSIV) stem components used in nuclear power generation, which are susceptible to thermal embrittlement. This presentation will demonstrate the software framework that was used for probabilistic fracture mechanics to determine the risk of failure of a component and/or the critical flaw sizes that require corrective action. This predictive risk assessment software framework taken together with monitoring and sensing technology could provide a quasi-real-time understanding of the state of a component along with a prediction of the future status of the component, assuming the service conditions.
