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

Abstract

Abstract: Abstract: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.

Key words: Key words:AP1000 nuclear power unit, steam turbine, operating floor, equipment arrangement, overhaul efficiency
