根据国内各在建核电厂的经验,对核岛燃料厂房辅助电动双梁桥式起重机的小车配置进行了优化改进。将原单独设置的安装小车的功能集成到运行小车上,并从功能、安全、环境、安装、维护、服务范围、成本等方面综合分析了方案改进的影响。结果表明该改进方案可以满足原功能要求,不会对其安全、可靠性产生不利影响。但有利于现场的安装和操作,并降低设备采购成本。
According to the experience of each nuclear power plant under construction in China, the configuration of the car for the auxiliary electric double girder overhead crane of Nuclear Island Fuel Plant is optimized and improved. Integrate the functions of the originally installed trolley into the running trolley and comprehensively analyze the impact of the program improvement from aspects of function, safety, environment, installation, maintenance, service range and cost. The results show that the improved scheme can meet the original functional requirements without adversely affecting its safety and reliability. But it is good for site installation and operation, and reduces equipment procurement costs.
