三门核电汽轮机运转层设备检修布置方案分析

Analysis on equipment maintenance layout scheme of turbine operating floor in Sanmen Nuclear Power Plant

三门核电有限公司AP1000机组汽轮机缸体尺寸大、转子质量大。在汽轮机大修期间，运转层部分区域要能够承受较大的局部载荷。根据^#1机组汽轮机全面解体检修状态，结合运转层的楼板设计数据及设备特点，采用相应的载荷均布措施以满足设备堆放的需求。该布置方案可确保整个平台的安全，提高检修效率。

The turbine cylinder of AP1000 unit of Sanmen Nuclear Power Company Limited has large size,and its rotator mass is large.Some partial regions of the operating floor must be able to bear larger local load during the steam turbine overhaul.According to the overhaul situation of the turbine of unit No.1,when which was disassembled overall,combining with the floor slab design data of the operating floor and the characteristics of the equipments,the relevant load uniform distribution measures were adopted to satisfy the requirement of equipment stacking. The scheme can ensure safety of whole platform and improve the overhaul efficiency.
