The train t3 station battery system provides an independent 250 volt OC power supply for power and control of the turbine driven auxiliary feedwater pump train. The limiting conditions of operation for the train H battery are consistent with the requirer..ents of the auxiliary feedwater system. The surveillance requirements for the train battery system are colisistent with <'l with requirements of the AB and CD station batteries. Standby circuits provide the capability to connect the train << battery system to the AS or Co station battery trains. The train N battery loads are derived from equipment in the turbine driven auxiliary feodwater pump tl ain and battery sizing is consistent with the functional requirements of these components.
