The power supply to the shutdown cooling isolation valves is shown below.

the numbers adjacent to valves indicate the source of power.

Train A valva UV655 UV653 UV651 Source of Power*

Train B UV656 UV654 UV652

  • Sources of Power (1)

Fed from Class IE MCC E-PHA-M35 (2)

Fed from Class IE MCC E-PHB-M36 (3)

Fed from Class IE Channel C battery through Class IE Inverter E-PKC-N43 (4)

Fed from Class IE Channel D battery through Class IE Inverter E-PKD-N44 Thus PVNGS meets the single failure criterion.
