核电厂安全级光缆鉴定内容研究

Research on Qualification Content of Safety-Grade Fiber Optic Cables in Nuclear Power Plant

针对核电厂特殊环境下应用的安全级光缆,开展安全级光缆鉴定内容及参考标准的研究,并建立安全级光缆的鉴定标准体系。根据安全级光缆在核电站应用的环境条件、功能要求,分析光缆与电缆的在结构和功能上的差异性、光缆自身光学特性,确定核电厂安全级光缆的鉴定内容、鉴定要求或规范,并建立核电厂安全级光缆鉴定标准体系。该鉴定标准体系可指导安全级光缆设计、选型、制造及鉴定活动,促进光缆设计、制造和采购的标准化。

Aiming at the safety-grade optical cables used in the special environment of nuclear power plant,the qualification content and reference standard of safety-grade optical cables are studied,and the qualification standard system of safety-grade optical cables is established.According to the environmental conditions and functional requirements of the application of safety-grade optical cable in nuclear power plant,the differences in structure and function of optical cables and electric cables,the optical characteristics of optical cables itself are analyzed and the qualification content of safety-grade optical cables in nuclear power plant,qualification requirements or specifications are determined,and the qualification standard system of safety-grade optical cables is setup.The qualification standard system can guide the design,model selection,manufacture and qualification of safety-grade optical cables,and promote the standardization of optical cable design,manufacture and procurement.
