Title | High Pressure Core Spray Pump Oil Leak |
Event Description | At 1023 CST on 11/07/2010, the HPCS System was declared inoperable due to a steady stream oil leak issuing from the lower motor bearing drain plug. The oil was being collected by an absorbent pad installed around the oil drain plug below the lower bearing sight glass. When the rag was removed from the drain plug, oil issued from the installed plug in a stream with the diameter of a number two pencil lead. River Bend personnel are currently making plans to repair the oil leak.
The licensee notified the NRC Resident Inspector. |
