核电工程建设进度控制的关键路径分析

以M310堆型为基础．结合大亚湾、岭澳工程的建设经验．研究核电工程建设进度控制的关键路径分析表明．核电工程建设的关键路径是核岛土建、核岛安装、与一回路冷态调试相关的单系统调试及联合调试。对于核岛土建．关键路径在反应堆厂房主体土建施工、预应力张拉、重点区域的土建房间移交和关键土建／安装接口移交；对于核岛安装．有4条关键路径：对于调试．分为冷态调试相关的16个单系统调试和联合调试两个阶段。

Analysis of Critical Paths for Schedule Control of Nuclear Power Projects

Study on the critical paths for the schedule control of nuclear power projects has been performed for reactor M310,based on the experiences from Daya Bay project and Ling Ao project.The study shows that the critical paths for the nuclear power project are from NI civil work,NI erection,commissioning of single systems directly serving the CFT to the joint-test.For NI civil work,the critical path is the main civil work of the reactor building,pre-stressing,handover of room s for important areas,and key CW-erection interfaces;there are four critical paths for NI erection;For startup,two stages can be identified: commissioning of 16 single systems directly serving the CFT and joint-test.
