Experimental stress analysis at reactor and plant components using hard- and software

Abstract

Abstract Increasing the reliability of pressure vessels the methods of experimental stress analysis are world-wide used for additional data. Components and software programs extend and improve the possibilities of the experimental stress analysis continuously. On-line display of stress results during applications is now possible. Field portable modular equipment with numerous instrument configurations meet the plant and field environmental constraints. The following paper describes a transportable quasistatic multipoint measuring unit with data processing and its use during the first pressure test of a nuclear reactor containment and further applications.
