Attachment Res onse to I.E.Bulletin 79-27, Item 2 Each alarm associated with a loss of power to these buses is addressed in the appropriate Annunciator List procedures (ONOP 0208.3 through ONOP 0208. 13).
Included in these procedures are verifying indications, automatic actions, and required operator actions.
In addition to the Control Panel
- alarms, the plant data logger provides redundant indication of a loss of power to the buses.
Alternate indications, powered from redundant buses, for all vital parameters are available to the operator.
Operators have been trained to use redundant indications to ensure reliable interpretation of information.
Procedure ONOP 0208. 14, "Deviation or Failure of Reactor Protection and Safety Related Hagan Instrumentation Channels,"
provides instructions for ensuring a transfer to redundant instrumentation in an off-normal condition.
Additionally, plant Emergency Procedures include warnings to use redundant indications.
Restoration of power to Vital AC or DC buses is accomplished in accordance with established plant operating procedures:
OP 9659. 1 (3A and 4B Batteries-Removing and Returning to Service),
OP 9659.2 (3B and 4A Batteries-Removing and Returning to Service),
and OP 9700. 1 (Instrument AC Power Supply-Operation of Normal and Spare Inverters).
Attaining cold shutdown is accomplished through use of Operating Procedures ONOP 0208. 1 (Shutdown Resulting from Reactor Trip or Turbine Trip), or OP 0205. 1 (Unit Shutdown, Full Load to Hot Shutdown Conditions) and OP 0205.2 (Reactor
- Shutdown, Hot Shutdown to Cold Shutdown Conditions).
