摘要
为应对核电厂在寿期内可能遇到的厂址条件变化、日常运维偏差、改造与改造累积效应等给设计基准带来的挑战问题,包括国际原子能机构(IAEA)、世界核电运营者协会(WANO)在内的一些国际组织提出在运核电厂应开展设计基准维护。明确设计基准的定义、内容及技术框架是开展设计基准的基础,但目前各个组织的定义却不尽相同。为此,本文首先研究了系统工程理论中通用的基准概念,比较分析了IAEA、WANO、美国核管会(NRC)以及我国在设计基准方面的定义和内容的异同,提出适用于在运核电厂的定义。基于上述结论,本文还进一步提出了分层级的核电厂设计基准内容技术框架,引入了设计基准维护的基本概念,为在运核电厂设计基准维护提供参考。
In order to deal with the challenges brought by the changes of nuclear power plants(NPP)’site conditions,deviations of daily operation and maintenance,modifications and their accumulations effects,design bases maintenance is promoted by international nuclear organizations such as IAEA and WANO.However,the definition of design basis and its content is still not clearly specified,or the definitions are inconsistent.In order to identify the definition for NPP in operation,the definition from system engineering is introduced and definitions from IAEA,WANO,NRC are discussed.Adapted definition is chosen and framework of design basis is discussed according to V-mode of NPP design.The application of the definition and design basis maintenance concept is also introduced base on the definition and hierarchy structure of design basis framework.
