摘要

压水型核反应堆压力容器的密封性能是保证核电厂安全运行的关键因素之一。为了探索反应堆压力容器密封性能的数值模拟技术

本文建立了CPR1000反应堆压力容器（RPV）密封结构的热弹塑性三维有限元分析模型

考虑了运行期间的载荷及载荷组合

得到了反应堆压力容器在升温、运行和降温瞬态过程中上下法兰的轴向分离量、径向滑移量以及螺栓载荷等。分析结果表明热弹塑性三维有限元密封分析模型能够较好地模拟密封结构的性能。

Abstract

Background: Pressurized water Reactor Pressure Vessel（RPV） sealing capability is one of the key factors to ensure the safety operation of nuclear power plants.Purpose: In order to explore the numerical simulation technology of the RPV sealing behaviors.Methods: In this paper

the 3-D thermal elastoplastic finite model is established

which based on the CPR1000 project.Results: The load and its combination of equipment during operation are considered

then the separation of RPV upper and lower flanges

radial slip and bolt loads etc.are also obtained.Conclusions: The results show the 3-D thermal elastoplastic finite model can simulate the sealing performance of the structure.
