Abstract

Advanced lifetime prediction methodologies are necessary in securing the safe and reliable operation of nuclear power plants. Stress corrosion cracking is the most common corrosion mechanism, which can cause a major integrity loss in metallic components. The cracking is caused by the combined action of corrosion, tensile stresses and a susceptible material. Risk-informed inspection is a more recent technique for better focusing of in-service inspections. Stress corrosion cracking is considered in the lifetime analyses. In addition to the metallic materials, there are also non-metallic components, whose lifetime can restrict the lifetime of a plant. In this chapter, lifetime prediction principles in case of concrete structures are also introduced.
