    Abstract - (Show below) - (Hide below)

    Specifies the performance and the functional characteristics of the electrical supply systems required for the instrumentation and control (I&C) systems important to safety of a nuclear power plant. Gives also guidance on the possible use of these supplies for other I&C systems. Defines the methods of application of the relevant IAEA Safety Guide NS-G-1.3.
