ABSTRACT (Limit to 1400 spaces, i.e., approximately 15 single-spaced typewritten lines)
On November 8, 2005, at 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br />, the 11 Safety Injection (SI) pump discharge valve (1 1SJ35) was found closed. The normally locked open valve was discovered closed by operators performing a pretest valve lineup for a normally scheduled SI pump surveillance test. The valve had been unlocked and closed on November 3, 2005 for check valve leak rate testing during refueling outage 1 R17. Following discovery of the closed discharge valve, Technical Specification Action Statement (TSAS) 3.5.2 b was entered and the valve placed in its proper position (locked open) and the TSAS exited. The SI pump discharge valve being inappropriately left shut effectively disabled one of the redundant trains of Safety Injection.
The direct cause was procedure non-compliance. The root cause was attributed to less than adequate application and enforcement of operator fundamentals. Corrective action was taken to revise the procedures and corrective actions are taking place to improve operator fundamentals.
This event is reportable under 10CFR 50.73(a)(2)(i)(B) "Any operation or condition which was prohibited by the Plants Technical Specifications" NRC FORM 366(6-2004)

(if more space is required, use additional copies of (if mre space is required, use additional copies of (If more space is required, use additional copies of NRC Form 366A)LER 311/2004-001 is an event where a sampling procedure directed valves to be verified open, contrary to the procedure sampling valves were not verified to be open and a Technical Specification required containment sample was not performed for thirty six hours. Corrective actions were specific to this event and would not have prevented this event from occurring.
SAFETY CONSEQUENCES AND IMPLICATIONS
There was no actual safety consequences associated with this event. The redundant train of ECCS was available during this event and a recirculation flowpath existed to protect the pump if a demand for system operation would have been initiated. Once the 11 SJ35 valve was discovered closed, actions were immediately taken to restore the system to operable status.
A review of this event determined that a Safety System Functional Failure (SSFF) IAW NEI 99-02 did not occur because this event would not have prevented the fulfillment of a safety function.
CORRECTIVE ACTIONS
- 1. Salem reviewed the extent of condition and revised ninety Operations and Chemistry procedures to correct the inadequate procedure guidance that directly lead to this event.
- 2. Station management has focused efforts on improving operator effectiveness. Management has placed a priority on allowing operators to focus on their primary functions. Operations department is in the process of implementing an Operator Fundamentals Program, consisting of weekly observations of non-licensed operators by Control Room Supervisors and weekly paired observations by Shift Managers. This will allow supervisors to focus on enforcement of operator fundamentals. These observations will be trended for crew and individual opportunities for improvement.
