Introduction

Nuclear power plant safety is based on the functions of the various categories of security settings can be guaranteed. Different functions of systems, equipment design, construction and operation Process to comply with different standards and norms. To this end, International Atomic Energy Agency (IAEA) for nuclear power plant safety instrumentation and control systems important EC (including computer software) should be classified on its safety significance, and determine the appropriate technical requirements and quality requirements, the instrument and control system System design, construction and operation of its security importance consistent. GB/T 15474-1995 "nuclear power plant instrumentation and control systems and their electrical equipment safety classification" is a nuclear power plant instrumentation and control systems According to the importance of safety equipment into the security level, safety and non-safety related equipment important equipment for each level provides assurance function, can By guarantees, performance guarantees, the ability to ensure resistance to environmental and quality assurance requirements. GB/T 15474-1995 Reference IEC 61226. 1993 "Nuclear power plant safety instrumentation and control important functional class" (in English) and RCC-P. 1984 "900MW PWR nuclear power plant system design Design and construction rules "establishment, but the IEC and RCC-P for instrumentation and control systems, the concept of security classification of different equipment, different classification methods, so GB/T 15474-1995 There are many problems in the course. In recent years, IEC standard architecture for nuclear power plant instrumentation and control systems important to safety made adjustments, and formed a IEC 61513 "Nuclear Power plant instrumentation and control systems important to safety - General requirements "(in English) for the first level, IEC 61226" Nuclear power plant instrumentation and control systems important to safety tester Control functional classification "(in English) as the second level, the relevant equipment standards for the third-level nuclear power plant engineering standards. IEC 61226. 2005 follows the IAEA Safety Standards NS-R-1 proposed nuclear power plant safety design requirements, and extends the Safety Guide NS-G-1.3 on real The importance of security classification policy applied function, the nuclear power plant instrumentation and control systems important to safety (including safety systems and safety related systems) power Can be classified according to their safety significance (A Class A, B, or C), and the provisions of the various types of functions and features, performance, reliability, resistance equipment Relevant technical requirements and quality requirements for environmental capacity. This revised standard adopts IEC 61226.2005 "Nuclear power plant instrumentation and control systems important to safety instrumentation and control the functional classification" (in English), not only correct N GB/T 15474-1995 IEC 61226 for the deviation, but also with reference to other existing standards IEC series of standards revision phase coordination. Nuclear power plant safety instrumentation and control important functional classification

1 Scope

This standard specifies the classification of the functions of systems and equipment important to safety instrumentation and control functions and the implementation of nuclear power plants, and identified Technical requirements for each category and quality in functionality, reliability, performance, durability and environmental aspects of the seismic performance assurance requirements. This standard applies to all instrumentation and control systems important to safety, the new nuclear power plant (including safety systems and safety-related instrumentation and control systems) design. Note. There is a reference power plant has been carried out and the design of new nuclear power plants according to the actual situation, the implementation of this standard may be conditionally.
