Methodology for pressurized thermal shock evaluation. Proceedings of the IAEA specialists meeting. Working material

摘要

The meeting was held within the scope of activities of the International Working Group, recognizing that the importance of the PTS phenomena and advances in the subject require regular information exchange in this field. The purpose of the meeting was to provide an opportunity to exchange information as well as new results in research and development, concentrating on the total PTS calculation and including PTS evaluation and application in RPV life time and integrity assessment. The papers presented at the meeting covered problems of thermohydraulics, RPV temperature-stress fields calculations, fracture mechanics approach to integrity assessment as well as discussions on PTS modeling, general procedures for RPV life assessment and mitigation methods other than RPV annealing.
