| Title | Failure to Follow Procedures Results in Draining of Emergency Core Cooling System Pump Oil |
| Description | On November 23, 2009, a self-revealing violation of Technical Specification 5.4.1.a was identified when a technician failed to follow procedure and emptied 45 gallons of oil from centrifugal charging Pump A rendering the pump inoperable. The technician was supposed to remove the temperature indicator for calibration but instead removed the thermowell which breached the lube oil subsystem of centrifugal charging Pump A. An unplanned entry into Technical Specification 3.5.2, Condition A, was made for approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />. The licensee entered this issue in their corrective action program as Condition Report 21993. The failure to follow station procedures and correctly remove the detector was a performance deficiency. The finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the significance of this finding using Phase 1 of Inspection Manual Chapter 0609.04, and determined that the finding was of very low safety significance (Green) because the pump was inoperable for less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Also, the finding did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The inspectors identified a human performance crosscutting in the area of work practices because self-checking and communication with the supervisor failed to prevent the event H.4.a] (Section 1R13) |
