• provides requirements and recommendations for the overall Electrical Power System . In particular, it covers interruptible and uninterruptible Electrical Power Systems including the systems supplying the I&C systems ;

• is consistent and coherent with IEC 61513. Like IEC 61513, this document also highlights the need for complete and precise requirements, derived from the plant safety goals. Those requirements are prerequisites for generating the comprehensive requirements for the overall Electrical Power System architecture, and for the electrical power supply sub-systems;

• has to be considered in conjunction with and at the same level as IEC 61513. These two standards provide a complete framework establishing general requirements for instrumentation, control, and Electrical Power System for Nuclear Power Plants.

   This document establishes: 
   
      
         
            

• the high level specification and requirement to implement a suitable Electrical Power System in a NPP that...
