On the reliability of creep damage assessment of power plant steam pipings

    Abstract

    The replica technique is an attractive method for the assessment of safety and minimum life time of creep loaded power plant components. This technique must be applied with care to ensure the observation of maximum creep damage since the replica inspections are spotwise in character. If properly carried out, the replica method has the advantage of not necessarily requiring information about the stress and temperature history of the components. The assessment rules that are used for the first inspections are conservative enough but even more damage can usually be tolerated especially in small and old power plants.
