Objective

Thermal fatigue is a recurring problem when LWR plants become older and life time extension activities are initiated. In general, the common thermal fatigue issues are understood and can be controlled by plant instrumentation systems. However, the Civaux 1 and other incidents indicate that certain piping system Tee's are susceptible to turbulent temperature mixing effects that cannot be adequately monitored by common thermocouple instrumentations, putting the reliability of integrity evaluation procedures in doubt. THERFAT proposes to review field data and perform advanced thermohydraulic flow simulations and stress and fracture analysis. Critical elements of the procedure will be investigated by targeted verification tests. Proposals will be made for improved thermal fatigue assessment procedures, screening criteria and for establishing a European Methodology on Thermal Fatigue.
