Abstract :
Salient features of the electric system for the Peach Bottom nuclear power plant include a variation on the normal unit-transformer scheme, effective application of the principle of duality for enhanced reliability of essential auxiliaries, and a unique utilization of main turbine — generator coastdown power for emergency-shutdown cooling. Peach Bottom is the prototype plant for the high-temperature gas-cooled reactor concept, in which steam conditions of 1,450 psi and 1,000 F are attained
