Effects of Material Property on Reactor Pressure Vessel Structure Integrity During Pressurized Thermal Shock Events

摘要: 介绍了承压热冲击（PTS）分析的背景和研究现状，阐述了基于确定性断裂力学的反应堆压力容器（RPV）结构完整性分析方法。分析了材料性能模式（线弹性和弹塑性）和辐照效应对PTS下RPV结构完整性的影响。

Abstract: The background and research status in quo of pressurized thermal shock (PTS) analysis were introduced and the reactor pressure vessel （RPV） structure integrity analysis method based on deterministic fracture mechanics was also explained in this paper. The research emphasis was focused on the effect on the RPV structure integrity of material mode and irradiation during PTS events.
