This system supplies power to the reactor system and its auxiliaries and
is designed to operate with a high degree of reliability to assure
reactor safety during all phases of operation and shutdown.
It includes all load control and protective devices, containment wiring,
metering, interlocking and alarms associated with electrical loads for
the reactor system. Power for the system normally is supplied by two
turbine-generators, each rated at 1,500 kw, 0.8 pf, 450-volts, 3 phase
and 60 cycles. For increased reliability, a double bus type arrangement
is used. In the event of a bus fault, an automatic transfer of all vital
loads to the other bus will occur. During normal operation, a circuit
breaker ties the two busses together.
