The resulting classification then determines relevant design criteria.The design criteria are the measures of quality by which the adequacy of each function inrelation to its importance to plant safety is ensured. In this standard, the criteria are those offunctionality, reliability, performance, environmental durability (including seismic) and qualityassurance (QA).This standard is applicable to all the information and command functions and the instrumentationand control (I&C) systems and equipment that provide those functions. The functions,systems and equipment under consideration provide automated protection, closed or openloop control and information to the operating staff. They keep the NPP conditions inside thesafe operating envelope and provide automatic actions, or enable manual actions, thatprevent or mitigate accidents, or that prevent or minimize radioactive releases to the site orwider environment. The I&C functions that fulfil these roles safeguard the health and safety ofthe NPP operators and the public.This standard follows the general principles given in IAEA safety code NS-R-1 and safetyguide NS-G-1.3, and it defines a structured method of applying the guidance contained inthose codes and standards to the I&C systems that perform functions important to safety in aNPP. This standard should be read in association with the IAEA guides and IEC 61513 inimplementing the requirements of IEC 61508 series.【中国标准分类号】: F69【国际标准分类号】: 27_120_20【页数】: 38P.;A4【正文语种】: 英语
