核电厂核岛主设备专用吊具载荷分析及系数取值方法研究

Load Analysis and Factors Determined Method of Special Lifting Device for NPP Nuclear Island Major Components

核电厂核岛主设备专用吊具用于反应堆一回路系统重要设备吊运,目前国内尚无针对性的设计标准规范。本文对其计算载荷、安全系数和试验载荷等进行分析,并结合标准规范和工程经验,对系数取值方法进行探讨,给出适用于主设备专用吊具的载荷计算公式,同时对设计经验进行总结。

At present, no standards is appropriative to the design of the special lifting device for the nuclear island major components, which is used to hoist the major components of reactor and main loop. This paper analyzes the specified rated load, safety factor and trial load of the special lifting device for NPP nuclear island major components, and gives the method to determine the factors according to the standards and experience. Furthermore, design experience and feedback are discussed in this paper.
