| 摘 要： | 考虑反应堆压力容器在役期间可能发生的典型的过冷瞬态(大破口失水和小破口失水事故),针对不同的裂纹形式运用MSC Marc程序进行断裂力学分析,进而确定容器在哪种裂纹和哪种瞬态下最危险,分析中考虑了堆焊层对断裂分析的影响. 运用有限元法进行断裂力学分析结果与理论解进行比较,二者吻合较好.

| Abstract: | The fracture mechanics analysis for different flaw is illustrated using MSC Marc. During the typical overcooling transients (LBLOCA and SBLOCA) for RPV in service, comparison is made to probe what kind of flaw and what kind of transient are most dangerous. The influence of the cladding on the fracture analysis is investigated. The fracture analysis results between finite element method and theoretic method have a good agreement. |
