New Construction Technology for Condenser Shell Module of Large Scale Nuclear Power Station

摘要

The shell is one important part of steam turbo-set condenser. Fangjiashan nuclear power project in Zhejiang Province is the domestic millions-kilowatt class PWR nuclear power plant. Its condenser shell modules have large size and heavy weight. At the same time by turbine house structure restriction, the traditional construction scheme is unable to satisfy the installation requirements. According to the condenser shell module structure characteristics and construction environment, the new construction technology such as four cranes integration operation, many times of changing hook, temporary hanging on the beam of steam turbine house, is studied and adopted. The supporting lifting frame is researched and developed. Four pieces of condenser shell modules with different hanging point size are successfully constructed. This can provide reference for the construction of similar equipment.
