The Areva Integrated and Sustainable Concept of Fatigue Design, Monitoring and Re-assessment: The paper was given at the 'ANSYS Conference & 26th CADFEM Users' Meeting 2008', Darmstadt/Germany, October 22 to 24, 2008

摘要

Figure 1 shows the typical arrangement of components within the primary circuit of a pressurised water reactor (PWR). The possible layout of measuring points for in-service fatigue monitoring is marked with full circles. Thus, the main role of the temperature measurement system can easily be identified. The principal modules of the Areva Fatigue Concept (AFC) are schematically shown and logically combined in Figure 2. It is obvious that for all plant life management activities, the quality of all fatigue analyses crucially depends on the determination of the real operational loads in the plant.
