摘要

摘要: 为解决秦山核电厂设冷水大厅中安全级与非安全级物项混杂布置、地震工况下可能产生交互作用的问题，采用试验分析方法，对布置在设冷水大厅中的安全级阀门和管道在地震工况下受其他非安全级风管、管道的影响进行研究和分析。试验中1:1复现了秦山核电厂设冷水大厅的物项尺寸和位置高度，通过平落、单摆、倾倒等多种交互方式进行测试，以管道、阀门的保压性能作为破坏准则，并对形变、冲击加速度进行测量和分析。为了验证试验的可靠性，采用数值模拟的方法对风管-管道交互作用的工况进行失效分析和对比，结果与试验方法保持了一致。最终研究结果表明，秦山核电厂设冷水大厅顶部3.6 m高处布置的风管、8 m高处布置的DN50的管道等非安全级物项不会对下方的安全级设冷水母管、阀门的功能和结构完整性产生破坏。

Abstract: In order to solve the problems of mixed arrangement of safety-related and non-safety-related items in the equipment cooling water system room of Qinshan Nuclear Power Plant and possible interaction under seismic conditions, by using the method of test and analysis, the safety-related valves and pipes arranged in the equipment cooling water system room are studied and analyzed under the influence of other non-safety-related ducts and pipes under seismic conditions. In the test, the size and height of the items in the equipment cooling water system room of Qinshan Nuclear Power Plant are reproduced 1:1, and the tests are carried out through various interactive methods such as flat fall, single pendulum, and dumping. Taking the pressure retaining performance of pipes and valves as the failure criterion, the deformation and impact acceleration are measured and analyzed. In order to verify the reliability of the test, the numerical simulation method is used to analyze and compare the failure of the duct-pipe interaction conditions, and the results are consistent with the test method. The final research results show that the non-safety-related items such as the duct arranged at 3.6 m above the top of the equipment cooling water system room and the DN50 pipe arranged at 8 m above the top of the equipment cooling water system room in Qinshan Nuclear Power Plant will not damage the function and structural integrity of the safety-related equipment cooling water system header and valve below.
