Electrical Power Distribution System for Clinch River Breeder Reactor Plant

This paper describes the auxiliary electric power system for the Clinch River Breeder Reactor Plant (CRBRP). The power systems covered are the utility grid interconnections, plant power supply systems medium and low voltage AC systems, 125/250V DC system, 120V vital AC system, and safety related AC distribution system. The paper also describes the mode of connection of non-Class 1E loads to Class 1E power systems, and a cross-connect feature between Division 1 and Division 2 Class 1E AC Power Systems.
