摘要
介绍了核电厂设备安全分级的目的以及安全分级的定义。比较了几种安全分级标准的差异,确定了安全分级的对象。根据安全分级的法规依据,阐述了安全功能的定义和种类,探讨了安全分级的方法、具体步骤和安全等级的分界,以及对确定为安全级机械设备的要求,最后提出了机械设备安全分级与电气设备安全分级的关系,以及机械设备安全分级与系统安全分级的关系。
The purpose and definition of the equipment safety classification in nuclear plant are introduced.The differences of several safety classification criterions are compared,and the object of safety classification is determined.According to the regulation,the definition and category of the safety functions are represented.The safety classification method,safety classification process,safety class interface,and the requirement for the safety class mechanical equipments are explored.At last,the relation of the safety classification between the mechanical and electrical equipments is presented,and the relation of the safety classification between mechanical equipment and system is also presented.
