Integrated Inspection Report 50-334/95-13 and 50-412/95-13 Letter Dated September 22,1995 2
VIOLATION (Severity Level IV, Supplement I)
Description of Violation (50-412/95-13-01)
Technical Specification 3.5.4 requires that reactor coolant pump seal injection flow shall be less than or equal to 28 gpm with the charging pump discharge pressure greater than or equal to 2410 psig and the seal injection flow control valve full open. With the seal injection flow not within the limit, adjust manual seal injection throttle valves to give a l
flow within the limit with the charging pump discharge pressure greater than or equal to 2410 psig and the seal injection flow control valve full open within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
Contrary to the above, between March 22 and March 23, and between July 23 and July 25,1995, reactor coolant pinnp seal injection flow exceeded 28 gpm and was not 4
restored within limits within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
Reason For The Violation j
The reason for the violation was a failure of the operator to follow operating procedure 2OM-7.4A, " Placing a Charging Pump in Standby or Inservice" through to completion.
Corrective Action Taken Procedure 2OM-7.4A has been revised (effective 10-5-95) to add requirements to initial and date each action step in the procedure and to perform a document review with a l
signature at the completion of the procedure. This will ensure completion of the step that measures total seal injection flow.
l Action Taken to Prevent Recurrence The equivalent procedure at Beaver Valley Unit 1 (BV-1) already contains a document review with a signature requirement.
A review of the BV-1 operating logs was
]
performed. No similar occurrences of missed surveillances of the reactor coolant pump 1
l seal injection flow after charging pump transfer were identified. Based on the results of this review it is felt that the BV-2 procedure revision will prevent recurrence. However, to further reinforce procedure compliance, licensed Unit 2 Operations personnel will review this event in conjunction with the requirements governing procedure usage.
Date When Full Comoliance Will Be Achieved We are in full compliance at this time. The review of this event and procedure usage requirements will be completed by November 23,1995.
