EPR核电厂安全级防火阀分级

Classification for Safety Classified Fire Damper in EPR Power Plant

EPR核电厂的安全分级采用功能分级指导物项分级的理念。对于具体设备,其分级包括设备的本体分级和仪控分级。通过对防火阀所属系统的功能分析确定其功能分级,再以功能分级为基础并结合系统运行工况确定防火阀的设备本体分级和仪控分级。

Functional Classification is used to direct item classification in EPR power plant. Equip-ment classification includes equipment body classification and equipment I＆C classification. For fire damp-er, functional classification is identified firstly according to the functional analysis on the relevant system, and then equipment body classification and equipment I＆C classification are identified on the basis of the functional classification combined with system operation analysis.
