March 8, 1976-
- Gas Turbine Becomes Inoperable at Millstone ailure sequence was:
he isolation condemsor was inoperable.
t was decided to start the emergency power system (a gas turbine and a iesel generatorlT as a precaution as hurricane Belle passed.
he gas turbine failed to run because the governor was out of adjustment.
he reactor was placed in cold shutdown since both the IC and the FWCI ystems were inoperable.
ctive action:
he governor was adjusted.
n purpose of failed system or component:
he I.C. is a natural circulation system which serves as a heat sink en the reactor is isolated.
he FWCI system provides for a source of high pressure coolant given Loca.
