適用范圍：This International Standard provides requirements for the software of computer-based I&Csystems of nuclear power plants performing functions of safety category A as defined byIEC 61226.According to the definition in IEC 61513, I&C systems of safety class 1 are basically intendedto support category A functions, but may also support functions of lower categories. Howeverthe system requirements are always determined by the functions of the highest categoryimplemented.For software of I&C system performing only category B and C functions in NPP as defined byIEC 61226, requirements and guidance of IEC 62138 are applicable.This standard provides requirements for the purpose of achieving highly reliable software. Itaddresses each stage of software generation and documentation, including requirementsspecification, design, implementation, verification, validation and operation.The principles applied in developing these requirements include:– best available practices;– top-down design methods;– modularity;– verification of each phase;– clear documentation;– auditable documents;– validation testing.Additional guidance and information on how to comply with the requirements of the main partof this standard is given in Annexes A to I.
