Title | Hpci Declared Inoperable |
Event Description | High Pressure Coolant Injection [HPCI] system was declared inoperable due to failure of alarm 'HPCI Turbine Exhaust Drain Pot Hi Level' to clear. The level switch associated with the alarm is the suspected failed component. When the line is drained there is evidence of water flow but the alarm does not clear. There are no other indications of the exhaust drain line filling with water.
As a precautionary measure, the HPCI auxiliary oil pump has been placed in pull-to-lock, which will prevent the auto initiation of HPCI. HPCI will be manually started when required and proper operations assessed to ensure the exhaust line is intact. Hourly draining of the HPCI turbine exhaust drain line has been instituted based on the previously established frequency of the alarm. HPCI is considered available. The NRC Senior Resident Inspector has been notified of this event. |
