摘要
人员设备闸门作为ACP100堆型安全壳上的最大贯穿件,其密封性能对防止放射性物质外泄起着至关重要的作用。该研究针对直接影响人员设备闸门密封性能紧密相关的门板和锁紧结构开展研究工作,通过有限元分析方法研究了锁紧结构位置和数量对闸门密封性能的影响,得到最优锁紧结构设计方案,解决了有限空间内尺寸增大后的人员设备闸门密封问题,并通过人员设备闸门样机的启闭锁紧试验和密封试验,进一步验证了门板锁紧结构设计方案的有效性。该研究成果为人员设备闸门优化奠定了技术基础,也可以为类似大型设备门板的密封性能研究提供参考。
The personnel equipment airlock,as the largest penetration component of the ACP100 reactor containment vessel,plays a crucial role in preventing the leakage of radioactive materials due to its sealing performance.This article mainly conducts research on door panels and locking structures that are closely related to the sealing performance of personnel equipment airlock.The influence of the position and quantity of locking structures on the sealing performance of the airlock was studied through finite element analysis method,and the optimal locking structure design scheme was obtained,which solved the problem of sealing for personnel and equipment airlock with increased dimensions in limited space.And the effectiveness of the door panel locking structure design scheme was further verified through the open-close and sealing tests of the personnel equipment airlock prototype.The results of this article lay a technical foundation for the optimization of personnel equipment airlock and provide reference for similar research of the sealing performance of large equipment door panels.
