Parametric Study on RPV Integrity Assessment under Pressurized thermal Shock

The objective of this study is to evaluate the structural integrity of a reactor pressure vessel during a pressurized thermal shock event by applying deterministic fracture mechnics. The deterministic fracture mechanics analysis was performed by using the three dimensional finite element models. The impacts of the input parameters, such as the crack location, the aspect ratio, and the cladding properties were reviewed with the corresponding...
