摘　　要：核电厂安全壳整体性试验是电厂调试过程中关键路径的重要主线工作,试验期间安全壳升压速率是影响该主线工作的重要因素。本文调研典型核电厂安全壳整体性试验的不同供气方式和升压速率,提出采用压缩空气系统为卡拉奇2号机组安全壳打压的方案。为验证方案的可行性,采用理想气体方程计算分析压缩空气系统供气方式下安全壳升压速率和试验时。根据供气方案实施了充压管线的改造设计和充压过程控制,并最终通过卡拉奇2号机组安全壳试验验证了本文研究内容的正确性。The containment integrity test of nuclear power plant is an important mainline work on the critical path of power plant commissioning,and the air pressure rising rate in the containment is an important factor directly affecting the mainline work.This article studies different air supplying methods and air rising rates of the containment integrity test in a typical nuclear power plant 9 and proposes a scheme for the containment test with the compressed air system in K-2.In order to verify the feasibility of the scheme,the ideal gas equation is used to calculate and analyze the pressure rising rate and time of the containment test under the air supplying method of the compressed air system.According to the air supply scheme,the reformation design of the charging pipeline and the charging process control were implemented.Finally,the correctness of the research content of this article was verified by the containment test of K-2.
