PD IEC/TR 63123:2017

What is PD IEC/TR 63123-I&C electrical power systems in nuclear power plant about? 

PD IEC/TR 63123 gives guidance for the application in the IAEA/IEC framework of the IEC 63147:2017/IEEE 497 corresponding to the adoption without modification of IEEE 497:2016. 

During their review of IEEE 497:2016, the experts of the review team noted that between the 2010 edition of the IEEE 497 and its 2016 edition: 

• Some IEC standards were added as normative references 
• An additional group of Type F variables was defined to cover parameters providing information to manage fuel damage scenarios and associated technical requirements were given 
• Several paragraphs were removed from 6.2 of the 2010 edition, which gave requirements 
• On diversity of design and defence in depth 
• The term “1E” was replaced by “safety system” 

Who is PD IEC/TR 63123-I&C electrical power systems in nuclear power plant for? 

PD IEC/TR 63123 on nuclear power plants. Instrumentation, control, and electrical power systems are applicable to: 

• Nuclear power stations 
• Atomic energy agencies 
• Atomic research organizations 
• Nuclear power plants Instrumentation, control, and electrical power systems manufacturers 
• Operators of NPP, systems evaluators and licensors 
• Nuclear safety authorities 
• Regulatory authorities 

Why should you use PD IEC/TR 63123-I&C electrical power systems in nuclear power plant? 

A nuclear power plant (NPP) has a large number of components and equipment, which are all coordinated by instrumentation systems. hence, the safety of nuclear power plant instrumentation is important for support and reliable power generation through controlling plant processes. 

PD IEC/TR 63123 provides you guidance for the application in the International atomic energy agency/ International Electrotechnical Commission IAEA/IEC framework of the IEC 63147:2017/IEEE 497 corresponding to the adoption without modification of IEEE 497:2016.
