某三代核电机组设备舱门技术特点及维修管理分析

EPR机组的设备舱设计与CPR1000机组有着明显不同,主要由闸门封头、闸门支撑结构、闸门导轨、重型地板组成;设备舱门的提升机构、设备舱门的锁紧方式以及设备舱通道的连接方式较二代机组都是全新的设计,其维修操作方法也就存在差异.为了提高设备可用性,保障设备在机组大修期间能够正常运行,该文通过研究设备舱的基本机构、工作原理...

Analysis on the Technical Characteristics and Maintenance Management of the Equipment Hatch of a Third-generation Nuclear Power Unit

The equipment hatch design of EPR is obviously different from CPR1000,which mainly composed of hatch,Tightening clamp,Hydraulic group,Heavy duty floor.Compared with the second generation nuclear power station,the Closure of the equipment hatch,the Lifting unit of the equipment hatch and the connection mode of the equipment hatch passage are all brand-new design,and there are also differences in the operation and maintenance methods.In order to improve equipment availability,ensure the normal operation of equipment during the outage can,in this paper,by studying the basic structure,working principle of equipment,analyzing the common mechanical failure of equipment doors during debugging as well as the prevention and treatment methods,sums up the equipment doors during daily and overhaul maintenance management strategy,for the security of nuclear power unit overhaul period has a positive significance.
