PSEG Nuclear LLC P.O. Box 236, Hancocks Bridge, New Jersey 08038-0236 JAN 2 7 2003 LRN-03-0033 Nuclear LLC United States Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 Special Report 354103-001 Hope Creek Generating Station Facility Operating License NPF-57 Docket No. 50-354 This special report is being submitted pursuant to the requirements of Hope Creek Technical Specification 3.3.7.5, ACTION 81 b, due to the North Plant Vent (NPV) high range noble gas monitor being inoperable for greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
On January 8, 2003 at 0401 hours0.00464 days <br />0.111 hours <br />6.630291e-4 weeks <br />1.525805e-4 months <br />, Technical Specification (TS) 3.3.7.5 "Accident Monitoring Instrumentation' Limiting Condition for Operation (LCO) and Offsite Dose Calculation Manual (ODCM) 3.3.7.11, Radioactive Gaseous Effluent Monitoring Instrumentation" Action Statements were entered to perform scheduled maintenance and testing.
Technical Specification 3.3.7.5, Action 81 states; "With the number of OPERABLE accident monitoring instrumentation channels less than required by the Minimum Number of Channels OPERABLE requirement, either restore the inoperable channel (S) to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or: a. Initiate the preplanned alternate method of monitoring the appropriate parameter(s), and b.
Prepare and submit a Special Report *. The requisite alternative monitoring was initiated and in place for the LCO duration.
The maintenance evolution was planned for approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> to complete.
However, a number of unexpected occurrences caused the work window to expand. Although the maintenance work on the NPV RMS was completed prior to the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, the planned testing on the NPV RMS was not completed prior to the LCO action time. The NPV RMS was returned to service January 12, 2003 at 0050, approximately 21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> beyond the LCO action time.
95-2168 REV. 7199
rJAN 2 7 2003 Document Control Desk LRN-03-0033 The apparent cause of exceeding the LCO action time was a failure of the work management planning process and execution oversight by management to recognize the full impact of the NPV RMS work (sample pump maintenance and surveillance testing) on the 72-hour LCO work window. This resulted in scheduling the NPV RMS sample pump maintenance work early and surveillance tests over an extended period. The NPV RMS was tagged and declared INOPERABLE for maintenance on January 8, 2003 at approximately 4 a.m.
The original schedule included the NPV RMS sample pump work only. This maintenance work window was scheduled for approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />. The remaining work (retest and surveillances) for the NPV RMS (which makes the monitor INOP when this testing is being performed) was scheduled to occur at least a day later. If the work had been laid out to include both the work and testing consecutively within the window and the allowed outage time guidance (per procedure NC.WM-AP.ZZ-0001, Work Management Process) for 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> LCO followed, the problems encountered would have been completed and the LCO exited prior to the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
The accumulative affect of the late start and other problems was that the NPV RMS was declared OPERABLE and returned to service approximately 21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> beyond the LCO action time (January 12, 2003 at 0050 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br />).
