SUMMARY OF FINDINGS
IR 05000293/2007-002; 01/01/2007-03/31/2007; Pilgrim Nuclear Power Station;Post-Maintenance Testing.The report covered a 13-week period of inspection by resident and region-based inspectors. One Green finding, which was a non-cited violation (NCV), was identified. The significance of most findings is indicated by their color (greater than Green, or Green, White, Yellow, Red)using IMC 0609, "Significance Determination Process" (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000.A.
NRC-Identified and Self-Revealing Findings
- Green.
A Green self-revealing NCV of 10 CFR 50, Appendix B, Criterion XVI,"Corrective Action," was identified for Entergy's failure to promptly correct a condition adverse to quality associated with the "B" emergency diesel generator (EDG). During the post overhaul surveillance of the "B" EDG on January 25, 2007, the "B" EDG experienced unexpected load oscillations of approximately 150 kilowatt (kW).
Subsequently, on February 23, 2007, oscillations of greater than 200 kW were seen, which resulted in the shutdown of the "B" EDG and an entry into a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Technical Specification (TS) Limiting Condition for Operation (LCO). Entergy corrected the kW load oscillations by replacing the mechanical portion of the "B" EDG governor. The "B" EDG was declared operable following successful testing. The issue was entered into Entergy's corrective action program. The inspector determined that this finding was more than minor because it wasassociated with the Equipment Performance attribute of the Mitigating Systems cornerstone; and, it affected the cornerstone objective of ensuring the reliability, availability, and capability of systems that respond to initiating events to prevent undesirable consequences. A Phase 3 SDP evaluation was necessary due to a potential for a greater than green finding as indicated in the site specific pre-solved Phase 2 worksheets. The Phase 3 evaluation concluded that the finding was of very low safety significance (Green). The inspector also determined that this finding had a cross-cutting aspect in the area of Problem Identification and Resolution, Corrective Action Program, in that Entergy personnel failed to thoroughly evaluate the unexpected kW oscillations. (Section 1R19)
B.Licensee-Identified Violations
Two violations of very low safety significance, which were identified by the licensee,have been reviewed by the inspector. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. The violations and corrective actions are listed in Section 4OA7 of this report.

Introduction.
A Green self-revealing NCV of 10 CFR 50, Appendix B, Criterion XVI,"Corrective Action," was identified when Entergy failed to promptly correct a condition adverse to quality associated with the "B" EDG.
As a result, the EDG was not capable of performing its safety function for 29 days.
Description.
On January 21, 2007, the "B" EDG was taken out of service for a plannedmaintenance overhaul. The overhaul consisted of inspections and preventive maintenance of the "B" EDG and support systems. One of the maintenance tasks was a flush and change of the "B" EDG governor oil. On January 25, 2007, following the completion of the overhaul, Entergy began a "B" EDG operability test which included a full load run to 2600 kW, in accordance with Entergy procedure 8.9.1, "Emergency Diesel Generator and Associated Emergency Bus Surveillance." During the operability run, operators noted unexpected oscillations in both kilowatts and generator amperage.
Kilowatt oscillations measured approximately 150 kW and generator amperage oscillations measured approximately 10 to 12 amperes. Procedure 8.9.1 states that if kilowatt oscillations are greater than 200 kW, then shutdown of the diesel engine is required. Although not exceeding the 200 kW abort criteria, Entergy entered the degraded condition in their corrective action program as CR 20070293. Entergy concluded that the oscillations were minor and, since they did not exceed the abort criteria in procedure 8.9.1, the operability run was successful and the "B" EDG was operable. Corrective actions planned for the kW oscillations included instrumenting the "B" EDG with a test recorder to obtain data to tune the governor in order to achieve a more stable operation of the "B" EDG. The corrective actions were scheduled to coincide with the next surveillance run on February 23, 2007, which was 29 days after the initial kW oscillations were observed.During the February 23, 2007, "B" EDG operability run, Entergy again noted kWoscillations at a full load of 2600 kW. Entergy noted this condition in their corrective action program in CR 20070703. Specifically, approximately 50 minutes into the full 9Enclosureload portion of the operability run, kW oscillations were observed at 100 kW andcontinued to increase during the run to 200 kW at a full load of 2600 KW. The full load run portion of the test was completed and the control room operator started to unload the engine in accordance with the procedure; as the load was reduced to 1800 kW, the kW oscillations were observed to exceed 200 kW. At this time, the control room supervisor ordered that the "B" EDG be secured due to the procedure abort criteria of greater than 200 kW being exceeded. Entergy's subsequent investigation included reviewing the test recorder data and sampling the oil from the mechanical portion of the governor (referred to as the "EGB"). Entergy found that the sampled oil from the EGB was gray and cloudy, and had a burnt smell, unlike the oil that was installed in the governor during the January 2007 overhaul. Initial testing of the EGB oil by the site Chemistry department indicated the presence of unidentified contaminants. Based largely on the condition of the governor oil sample, Entergy concluded that the EGB required replacement.
Entergy Maintenance replaced the EGB on February 24, 2007, and tuned the governor system in accordance with Entergy procedure 3.M.3-61.7, "Woodward Governor Tuning." The governor oil system was vented, and on February 25, 2007, an operability run was commenced. During the operability run, load oscillations did not exceed 30 kW.
Entergy further tested the governor by performing a load-reject test of the "B" EDG. The purpose of this test was to monitor the response of the governor control system when a large load (core spray pump) was started and tripped. This test was satisfactorily completed. The "B" EDG was then declared operable.On March 7, 2007, Entergy shipped the EGB to the vendor for testing and failureanalysis. When tested by the vendor, the EGB lost pressure within a few minutes and the test was aborted. The vendor performed an inspection of the EGB and found shreds of aluminum in the governor oil. The source of the aluminum was determined to be an aluminum label that was originally attached to the shutdown solenoid valve located inside the EGB. Entergy concluded that the most likely scenario was that the label was installed during maintenance in 2002 and became dislodged as a result of the governor oil change during the January 2007 engine overhaul. The label was then ground up by the relay bushing gears. The ground particles then clogged the internal passages of the governor, resulting in a degraded governing ability of the EGB. This resulted in the unexpected kW oscillations of the "B" EDG.Entergy conducted an extent of condition review and tested the oil from the "A" EDGgovernor. Test results showed that the oil in the "A" EDG governor was acceptable with no aluminum particles present. The root cause investigation concluded that this issue was isolated to the "B" EDG. Entergy analyzed the effects that the 200 kW oscillations would have had on connected emergency core cooling system loads while the "B" EDG operated. The frequency changes resulting from 200 kW oscillations were found not to cause any premature tripping of loads or other adverse consequences.Analysis. The inspector determined that the failure to promptly correct a conditionadverse to quality associated with the "B" EDG was a performance deficiency. While the kW swings during the January test did not exceed the 8.9.1 abort criteria, the 10Enclosureoscillations were not typical of historical performance. The inspector concluded that the"B" EDG was inoperable for 29 days because the EGB function was impacted with an ongoing degradation mechanism. The inspector determined that this finding was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone; and, it affected the cornerstone objective of ensuring the reliability, availability, and capability of systems that respond to initiating events to prevent undesirable consequences.The finding was determined to be of very low safety significance (Green) in accordancewith Inspection Manual Chapter (IMC) 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations." The inspector initially evaluated the significance of this finding using IMC 0609, Appendix A, and determined that a Phase 2 analysis was required since the finding represented an actual loss of safety function of a single train for greater than the TS allowed outage time. An NRC Senior Reactor Analyst (SRA) determined a Phase 3 analysis was necessary due to the indication of a greater-than-green finding using the site-specific Phase 2 notebook. The SRA used the Pilgrim Standardized Plant Analysis Risk (SPAR) model to analyze the finding and noted differences in how the Phase 2 notebook and the SPAR model credited the use of the 23kV offsite power source and the SBODG. The SPAR model dominant cutsets are a station blackout with the HPCI train unavailable and a stuck open safety relief valve. The SRA determined that the SPAR model correctly characterized the significance of the finding. The SRA further evaluated the potential risk contribution from large early release frequency and the contribution from external events including seismic and fire initiated loss of offsite power events. Based on this review, the SRA concluded that the finding was of very low safety significance (Green).The inspector determined that this finding had a cross-cutting aspect in the area ofProblem Identification and Resolution, Corrective Action Program, in that Entergy personnel failed to thoroughly evaluate the unexpected kW oscillations.Enforcement. 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," requires thatmeasures be established to assure that conditions adverse to quality are promptly identified and corrected. Contrary to the above, on January 25, 2007, Entergy failed to promptly correct a condition adverse to quality when load swings of 150 kW were found during a post maintenance operability run of the "B" EDG. Because this violation is of very low safety significance and has been entered in Entergy's corrective action program (CR 20070703), this violation is being treated as an NCV, consistent withSection VI.A.1 of the NRC Enforcement Policy: NCV 05000293/20070201, InadequateEvaluation of Unexpected Emergency Diesel Generator Load Swings

a. Inspection Scope
(2 samples)The inspector reviewed Entergy's plans and preparations for the refueling outagescheduled to begin in April 2007. This inspection activity represents two samples.*Review of Refuel Outage Plan. The inspector reviewed the refueling outage(RFO) -16 Outage Shutdown Risk Assessment and procedure TP07-023, "Compensatory Measures," to verify that Entergy addressed the outage impact on defense-in-depth for the five shutdown critical safety functions: electrical power availability, inventory control, decay heat removal, reactivity control, and containment. The inspector reviewed how Entergy planned to provide adequate defense-in-depth for each safety function, and the planned contingencies to minimize the overall risk where redundancy was limited or not available.
Consideration of operational experience was also assessed. *New Fuel Receipt and Inspections. The inspector observed licensee activities toreceive and inspect new fuel for Operating Cycle 17, install fuel channels, and store the fuel in the spent fuel pool. The inspector used the following references for the review: Procedure 4.1, "Receiving and Handling of Unirradiated Fuel Assemblies;" Procedure 4.2, "Inspection and Channeling of Nuclear Fuel;" TS 3.7, "Containment Systems;" and UFSAR Section 10.3, "Spent Fuel Storage."

.2 Annual Sample - Station Blackout Diesel Generator
a. Inspection Scope
(1 sample)The inspector reviewed Entergy's corrective actions for the failure of the SBODG to starton demand in January 2005. Specifically, on January 23, 2005, following the loss of electrical power to its auxiliary equipment, operations attempted to start the SBODG, as specified in procedure 2.4.146, "Station Blackout Diesel Generator," when jacket water outlet temperature dropped to 80F. The diesel generator failed to start, tripping on lowlube oil pressure. The inspector reviewed responses to CRs 200501177, 200500392, and 200500256; and the procedure changes specified for procedures 2.2.146, "Station Blackout Diesel Generator;" 2.4.16, "Distribution Alignment Electrical System Malfunctions;" and 2.4.A.23, "Loss/Degradation of 23 kV Line."
b. Findings and Observations
No findings of significance were identified. However, a negative observation regardingEngineering Department performance was noted during this review. Engineering's original proposed solution, to increase the jacket water outlet temperature from 80F to 85F, lacked an adequate basis to assure the diesel engine would start. Afterprompting by Operations Department personnel, the issue was re-evaluated and Entergy determined that the appropriate corrective action was the revision of station procedures to require starting the SBODG as soon as possible following a loss of power to its auxiliary equipment. Prior testing had demonstrated the SBODG was able to start 15Enclosure10 minutes following loss of power to its auxiliary equipment. This inspection activityrepresents one sample.4OA3Event Follow-up (71153)
a. Inspection Scope
(4 samples)The inspector assessed the control room operator performance during the followingplanned and un-planned non-routine evolutions. The inspector evaluated personnel performance based on control room observations, interviews, and reviews of operator logs, alarm response procedures, and operating procedures. This inspection activity represents four samples.*The inspector observed a planned plant power reduction to 62 percent power onJanuary 26-27, 2007, per procedure 2.1.14, "Station Power Changes," and power suppression testing, per procedure 9.32, "Power Suppression Testing."
The inspector used power maneuvering plan MAN.C16-76 as a reference for this review. The inspector reviewed Entergy's actions to identify a potential fuel leak, suppress the fuel defect, and follow the fuel pre-conditioning operating guidelines.*The inspector reviewed the operator response to a partial loss of the 23 kVpower supply on January 26, 2007, due to a line failure on the site access road.
The inspector reviewed the operator actions per procedure 2.4.A.23, "Loss/Degradation of 23 kV Line," and the actions to restore plant conditions following the restoration of power. *The inspector responded to the site on March 17, 2007, to review Entergy'sactions to shutdown and cooldown the plant in response to increasing drywell leakage. During plant operations at 86 percent power in end-of-cycle coast down on March 17, 2007, the operators noted unidentified drywell leakage increased from 0.57 gallons per minute (gpm) to 1.16 gpm over a 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> period. The operators began a controlled shutdown at 12:30 p.m. to place the plant in cold shutdown in order to investigate and repair the leakage source. The operators reduced reactor power using recirculation flow and control rods, and manually scrammed the reactor from 30 percent power at 4:55 p.m. on March 17, 2007. The reactor responded as expected during the scram and safety systems operated properly. Reactor Building and containment isolations and RWCU system isolation occurred as expected due to low reactor vessel level following the scram [Event Number 43235]. Drywell unidentified leak rate increased to a maximum value of 2.59 gpm, and then decreased as the reactor was cooled down and depressurized. Drywell leakage remained below the TS 3.6.C.1 limits for total (25 gpm) and unidentified (5 gpm) leak rate.
16EnclosureThe plant entered cold shutdown at 4:32 pm on March 18, 2007. Entergypersonnel entered the drywell and identified a packing leak from RWCU system valve MO-1201-85, which was subsequently repaired (MR 07104403). This item was entered into Entergy's corrective action program as CR 20070949 to investigate the root cause of the packing leak. During the above sequence of events, the inspector observed the operatorsreduce power per power maneuvering plan MAN.C16-84 and shutdown the reactor by inserting a manual scram per procedure 2.1.6, "Reactor Scram." The inspector observed Entergy actions to implement plant cooldown activities using procedure 2.1.5, "Controlled Shutdown from Power," and 2.1.7, "Vessel Heatup and Cooldown." The inspector reviewed Entergy's scram report and verified that the cause of the shutdown was understood and corrected prior to plant restart.
Additional references used during this review are listed in the attachment to this report.*The inspector reviewed Entergy actions on March 18-19, 2007, to restart theplant using procedures 2.1.1, "Startup from Shutdown," and 2.2.70, "Drywell and Torus Inerting," and power maneuvering plan MAN.C16-84. The startup activities observed included the approach to criticality, rolling the main turbine, and synchronizing the unit to the electrical grid. The reactor was restarted at 3:08 p.m. on March 19, 2007. The unidentified leak rate in the drywell was 0.03 gpm following the resumption of plant power operations. The inspector reviewed Entergy actions to enter deficiencies into the corrective action program. The references used during this review are listed in the attachment to this report.
b. Findings
No findings of significance were identified.4OA6Meetings, Including ExitExit Meeting SummaryOn April 5, 2007, the inspection results were presented to Mr. Kevin Bronson, andmembers of his staff. The inspector asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.4OA7Licensee-Identified ViolationsThe following violations of very low safety significance (Green) were identified byEntergy and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as a Non-Cited Violation.
17Enclosure*TS 5.4.1 requires, in part, that Entergy establish and implement procedures tocover the activities specified in Regulatory Guide 1.33, Appendix A. Contrary to the above, the requirements contained in procedures 8.5.3.1, "Reactor Building Closed Cooling Water System Quarterly and Biennial Comprehensive Operability," and 1.3.34.2, "Limiting Conditions For Operation Log," were not implemented on February 24, 2007, for a failed surveillance test of the "D" RBCCW pump (P-202D). Specifically, operators did not identify the pump's total dynamic head of 81.5 ft was below the minimum allowed total dynamic head of 82 ft. The error was identified by system engineering on February 26, during review of the completed procedure. Condition Reports 200700719 and 200700737 were issued and operations entered P-202D into tracking LCO (Track-1-07-0016), as required by procedure 1.3.34.2. The finding is more than minor per MC-0612, Appendix E, examples 2a and 2c, in that the total dynamic head was below the minimum specified value. The issue is not greater than Green (very low safety significance) because the RBCCW loop remained operable due to the availability of the two remaining pumps.*TS 5.4.1 requires, in part, that procedures be established and implementedcovering the activities specified in Regulatory Guide 1.33, Appendix A.
Contrary to the above, plant personnel did not implement the requirements of procedures 7.3.36, "Offgas Sampling and Analysis," and 7.4.63, "Process Radiation Monitoring Setpoints," when samples of the offgas system indicated the setpoints for offgas radiation monitors 1705-3A/B were non-conservative. The setpoints are used to assure the controls of Offsite Dose Calculation Manual (ODCM) 3.1.2 are met. The discrepancy was identified after 26 samples had been taken from January 16, 2007, through March 3, 2007. The licensee entered action statement LCO-ACT-1-07-035 and completed actions to adjust the setpoints on March 3, 2007. The issue was more than minor per MC-0612, Appendix A, because the non-conservative setpoints impact the public radiation safety cornerstone which involves radiological effluent monitoring and was contrary to the controls in the ODCM 3.1.2. The issue was not more than Green because offgas release rates remained well below the levels specified in TS 3.8.1, and other radiation monitors (post-treat and main stack) in the effluent pathway were operable and would have alerted the operators of the need for action. This discrepancy was entered into the Entergy's corrective action system as CR 20070784.ATTACHMENT:
