UNITED STATES NUCLEAR REGULATORY COMMISSION May 5, 2008

SUBJECT:

HOPE CREEK GENERATING STATION - NRC INTEGRATED INSPECTION REPORT 05000354/2008002

Dear Mr. Levis:

On March 31, 2008, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Hope Creek Generating Station. The enclosed integrated inspection report documents the inspection results discussed on April 14, 2008, with Mr. Barnes and other members of your staff.

The inspections examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

The report documents one NRC-identified finding of very low safety significance (Green). The finding was determined to involve a violation of NRC requirements. Additionally, two licensee-identified violations determined to be of very low safety significance are listed in this report.

However, because of their very low safety significance and because they are entered into your corrective action program, the NRC is treating these findings as non-cited violations (NCVs)

consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Hope Creek Generating Station.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/

SUMMARY OF FINDINGS

IR 05000354/2008002; 01/01/2008 - 03/31/2008; Hope Creek Generating Station; Other

Activities.

The report covered a three-month period of inspection by resident inspectors and an announced inspection by a regional health physics specialist. One Green non-cited violation (NCV) was identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter (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 NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversignt Process,

Revision 4, dated December 2006.

NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green.

The inspectors identified a non-cited violation of Technical Specification (TS)6.2.2.d, Unit Staff, because four individuals worked beyond the TS limit of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in a 7-day period without proper authorization. Additionally, PSEG did not approve the work hour deviations of 20 individuals prior to them working the hours. PSEG entered this issue into their corrective action program in notification 20357323.

The finding was determined to be more than minor because, if left uncorrected, exceeding TS work hour limits would increase the likelihood of a fatigue-related human performance error during normal plant operations or plant events. The inspectors used Inspection Manual Chapter 0609 Appendix M, "Significance Determination Process Using Qualitative Criteria," because other significance determination process guidance was not suited to provide reasonable estimates of the significance of this inspection finding. With the assistance of Region 1 management and a Senior Risk Analyst, the inspectors determined that the finding was of very low safety significance (Green) because there were no human performance issues that were linked directly to worker fatigue. The finding had a cross-cutting aspect in the area of human performance because PSEG did not follow procedure LS-AA-119 to authorize deviations from working hour limits described in Technical Specification 6.2.2.d.

(H.4(b)) (Section 4OA5)

Licensee Identified Violations

Violations of very low safety significance that were identified by PSEG have been reviewed by the inspectors. Corrective actions taken or planned by PSEG have been entered into PSEG's corrective action program. These violations and corrective actions tracking numbers are listed in Section 4OA7 of this report.

REPORT DETAILS

Summary of Plant Status

The Hope Creek Generating Station (HCGS) began the inspection period operating at full power. HCGS operators reduced plant power to 20% on January 5, 2008, to repair a steam leak on the main turbines high pressure turbine casing. HCGS returned to full power operation on January 7. Reactor power was reduced to 78.5% due to an intermediate recirculation pump runback on February 8. The runback was caused by an unplanned trip of the C secondary condensate pump breaker. HCGS returned to full power on February 8 (see section 71153).

a. Inspection Scope

The inspectors reviewed PSEGs program for gathering, evaluating and reporting information for the performance indicators (PIs) listed below. The inspectors used the definitions and guidance contained in (Nuclear Energy Institute) NEI 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 5, to assess the accuracy of PSEGs collection and reporting of PI data. The documents reviewed by the inspectors are listed in the Attachment.

Cornerstone: Initiating Events

  • Unplanned Scrams per 7000 Critical Hours
  • Unplanned Scrams with Complications
  • Unplanned Power Changes per 7000 Critical Hours The inspectors reviewed the data reported for these PIs for the period January 1 through December 31, 2007. The records reviewed included PI data summary reports, licensee event reports, monthly operating reports, and operator narrative logs. The inspectors verified the accuracy of the number of critical hours reported, and interviewed the system engineers responsible for data collection and evaluation.

b. Findings

No findings of significance were identified.

4OA2 Identification and Resolution of Problems

.1 Review of Items Entered into the Corrective Action Program:

As required by Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of all items entered into PSEG's corrective action program. This was accomplished by reviewing the description of each new notification, reviewing the details of selected notifications, and attending daily management review committee meetings.

4OA3 Event Followup

.1 Main Turbine Control Valve (TCV) #2 slow closure on January 14, 2008

a. Inspection Scope

On January 29, 2008, while operating at 100% power, Hope Creek experienced a slow closure of TCV #2. A small pressure transient occurred as a result of the slow valve closure, with peak reactor thermal power reaching 100.4%. All plant equipment responded to the pressure transient as designed. Following the transient, operators maintained the plant at 99% reactor power. Operators reduced reactor power to 50% to repair TCV #2 on February 2, 2008, to perform inspections and repairs of the other three TCVs. PSEG determined that vibration induced failure of the TCV position indication transmitter caused the slow closure. PSEG modified the position indicators on all four TCVs to mitigate the effects of vibration induced failure and also installed monitoring equipment to improve the capability to identify degrading position indicators.

The inspectors responded to the control room following the transient to observe post-transient operations. The inspectors observed and participated in interviews with plant personnel to gain an understanding of how operators and plant equipment responded to the transient. The inspectors observed engineering technical analysis and evaluation meetings and interviewed engineers to gain an understanding of the transient, to assess PSEGs evaluation process, and to evaluate whether PSEG identified and corrected the cause of the transient. Documents reviewed are listed in the Attachment.

b. Findings

No findings of significance were identified.

.2 Secondary Condensate Pump Trip and Recirculation Pump Runback on February 8,

2008

a. Inspection Scope

On February 8, 2008, while operating at 100% power, the C secondary condensate pump (SCP) power supply breaker tripped, which caused an intermediate reactor recirculation pump runback to 78.5% power. All power plant systems performed as designed during and following the transient. PSEG reviewed plant conditions prior to, during, and following the transient to verify that the plant responded appropriately.

PSEG determined that the C SCP low suction pressure signal conditioner card had failed, resulting in the SCP trip. Corrective actions included replacing the failed logic card associated with the C SCP, as well as an extent of condition review. Documents reviewed are listed in the Attachment.

The inspectors responded to the control room following the transient to observe post-transient operations. The inspectors observed and participated in interviews with plant personnel to gain an understanding of how operators and plant equipment responded to the transient. The inspectors observed engineering technical analysis and evaluation meetings and interviewed engineers to gain an understanding of the transient, to assess PSEGs evaluation process, and to verify that PSEG appropriately resolved the issues that led to the transient. Documents reviewed are listed in the Attachment.

b. Findings

No findings of significance were identified.

.3 (Closed) LER 05000354/2007-002-001, Performance of Vital Bus Surveillance

Caused a Partial Loss of Feed Resulting in a Manual Scram On May 29, 2007, while operating at 100% reactor power, a manual scram was initiated in anticipation of a low reactor water level condition. During monthly relay testing, an unexpected slow (dead bus) transfer of a 4 KV Class 1-E bus from the normal to alternate source occurred. As a result, a non-safety related motor control center (MCC) was also de-energized resulting in a loss of two of three reactor feedwater pumps. Reactor water level could not be maintained in the required band; therefore, the operators manually scrammed the reactor in accordance with station procedures. This LER provided supplemental information to LER 2007-002-00 regarding the cause of the event. The supplemental information did not change the inspectors disposition of the event. The NRC documented the performance deficiency and associated enforcement aspects of this issue in NRC report 05000354/2007003. This LER is closed.

.4 (Closed) LER 05000354/2007-003-00, Grab Samples Not Performed As Required by

Technical Specification 3.3.7.1 On July 1, 2007, Hope Creek operators observed the main condenser offgas flow rate increasing. As required by the main condenser vacuum abnormal operating procedure, the control room supervisor (CRS) directed radiation protection technicians to enter correction factor changes into the offgas pretreatment radiation monitoring system (RMS) in anticipation of offgas flow approaching an instrument limit of 75 cubic feet per minute (CFM). The offgas pretreatment RMS must be declared inoperable when offgas flow increases to 75 cfm, but can be declared operable once the required correction factor changes are entered into the RMS. On July 4, 2007, offgas flow decreased below 75 cfm. The CRS directed radiation protection technicians to remove the correction factors from the RMS. The technicians stated that no correction factors were ever entered into the RMS, but the alert setpoint was raised instead. The offgas pretreatment RMS was declared inoperable from July 1 through July 4, 2007. Technical Specification 3.3.7.1 required grab samples to be taken at least once per 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> period and analyzed within the following 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. PSEG did not take the required grab samples during the period of July 1 through July 4, 2007. The inspectors reviewed the LER and associated root cause to verify that PSEG complied with the reporting requirements in 10 CFR 50.73. The enforcement aspects of this issue are documented in section 4OA7. This LER is closed.

.5 (Closed) LER 05000354/2008-001-00, Reactor Recirculation Pump Motor generator Set

Scoop Tube Mechanical and Electrical Stop Over-Speed Set Points Found Outside of Technical Specification Limits On January 19, 2008, during the performance of 18-month Technical Specification Surveillance Requirement (SR) 4.4.1.1.3, which demonstrated the operability of the reactor recirculation pump motor generator (MG) set scoop tube mechanical and electrical stops, the A and B MG set mechanical and electrical stops were found set non-conservatively high. PSEG immediately set the MG mechanical and electrical stops at the appropriate setting prescribed by station procedures. PSEG determined through an apparent cause analysis that the most likely cause of the issue was that PSEG changed the operational methodology for matching recirculation loop flows in June 2006, that is, they stopped matching recirculation drive flows and began matching jet pump loop flows to meet recirculation flow mismatch requirements in TS. This change reduced the net resistance to flow in the recirculation loops and made the recirculation pumps more efficient at driving flow. As a result, the previously set mechanical and electrical stops were too high. PSEG also determined that the change in hydraulic behavior was not promptly detected. PSEG created corrective actions to evaluate and improve system monitoring techniques.

PSEG determined that with the mechanical and electrical stops set high, no safety limit maximum critical power ratio or fuel rod thermal mechanical limits would be exceeded even if both pumps ran up to their mechanical stops. Furthermore, by procedure, Hope Creek does not operate reactor recirculation pumps in master manual mode; therefore, a single failure could not have caused both recirculation pumps to fail in a manner that resulted in both pumps speeding up to their mechanical stops.

The inspectors reviewed the LER, the apparent cause, and interviewed cognizant engineers. No findings of significance were identified. The inspectors identified one violation of T.S. 3.4.1.1, Recirculation Loops. The inspectors determined the finding was not more than minor because, as described above, no safety limits would have been exceeded. This LER is closed.

a. Inspection Scope

The inspectors reviewed PSEGs record of working hours for several plant employees during fourteenth refueling outage (October 25 through November 6, 2007). The inspectors also reviewed notifications in the corrective action program and interviewed employees and station management.

b. Findings

Introduction.

The NRC identified a non-cited violation of Technical Specification (TS)6.2.2, "Unit Staff," when some PSEG employees exceeded work hour limits specified by TS 6.2.2 and plant procedures. The finding was determined to be of very low safety significance (Green).

Description.

The inspectors identified that PSEG did not evaluate and approve working hour deviations for four individuals who worked more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in a 7-day period.

Additionally, there were 20 examples of TS work hour limit deviation forms that were not completed in accordance with procedure LS-AA-119, "Overtime Controls." Specifically, the deviation forms were not signed prior to the individuals exceeding the limit of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in a 7-day period.

The inspectors determined that a performance deficiency existed because PSEG did not manage the work hours of some individuals who perform safety-related functions within the limits of Technical Specification 6.2.2 and procedure LS-AA-119. The inspectors concluded that it was reasonable for PSEG to foresee and correct deficiencies with managing the work hours of employees within the guidelines of TS 6.2.2 because procedure LS-AA-119 described the process of maintaining, approving, and documenting worker hours to comply with TS 6.2.2.

Analysis.

The finding was determined to be more than minor because, if left uncorrected, exceeding TS work hour limits would increase the likelihood of a fatigue-related human performance error during normal plant operations or plant events. The inspectors used Inspection Manual Chapter 0609 Appendix M, "Significance Determination Process Using Qualitative Criteria," because other significance determination process guidance was not suited to provide reasonable estimates of the significance of this inspection finding. With the assistance of Region 1 management and a Senior Risk Analyst, the inspectors determined that the finding was of very low safety significance because there were no human performance issues linked directly to worker fatigue.

The finding had a cross-cutting aspect in the area of human performance associated with work practices because personnel did not follow procedures. Specifically, PSEG did not follow procedure LS-AA-119 to authorize deviations from working hour limits described in Technical Specification 6.2.2.d. PSEG determined that personnel did not follow the procedure because they were not adequately trained on its use. (H.4(b))

Enforcement.

Technical Specification 6.2.2.d, "Unit Staff," requires that administrative procedures shall be implemented to limit the working hours of unit staff that perform safety-related functions. Additionally, the TS states that any individual should not be permitted to work more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in any 7-day period. Any deviation from the above guidelines shall be authorized by the appropriate department manager in accordance with established procedures and with documentation of the basis for granting the deviation. Contrary to the above, PSEG did not authorize four individuals to exceed the Technical Specification limit of working no more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in a 7-day period for the time period of October 25 through November 6, 2007. Furthermore, PSEG did not authorize an additional 20 individuals to exceed the Technical Specification limit of working no more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in a 7-day period prior to the work being performed.

Because this issue was of very low safety significance and PSEG entered this issue into their corrective action program (notification 20357323), this finding is being treated as a non-cited violation, consistent with section VI.A of the NRC Enforcement Policy. (NCV 05000354/2008002, Improper Management of Working Hours During Refueling Outage)

4OA6 Meetings, Including Exit

On April 14, 2008, the inspectors presented their findings to members of PSEG management led by Mr. George Barnes. None of the information reviewed by the inspectors was considered proprietary.

4OA7 Licensee-Identified Violations

The following violations of very low significance (Green) were identified by PSEG and are violations of NRC requirements that met the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as non-cited violations

  • Technical Specification 6.8.1.j, Procedures and Programs, requires that PSEG implement a quality assurance program for the effluent monitoring program. The quality assurance program for the effluent monitoring program includes participation in an interlaboratory comparison program to verify the quality of radioactive effluent sampling analysis performed. Contrary to the above, PSEG did not participate in an interlaboratory comparison program for the second quarter of 2006, and had multiple comparison failures that were not investigated or documented in their corrective action program (CAP). This was identified in PSEG=s CAP as notifications 20347099 and 20354301. This finding is of very low safety significance because while it impaired PSEG=s ability to assess dose, there was no dose impact to a member of the public.
  • Technical Specification (TS) 3.3.7.1, Monitoring Instrumentation, requires that PSEG take grab samples at least once in every 8-hour period and analyze the sample within the next 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> when the offgas pretreatment radiation monitoring system is inoperable. Contrary to the above, PSEG did not take the required grab samples when the offgas pretreatment RMS was inoperable from July 1 through July 4, 2007. The issue was documented in their corrective action program in notification 20328891. Additionally, PSEG conducted a root cause analysis to determine the causes of the error. PSEG determined that the root cause was that radiation protection technicians did not have adequate procedural guidance to perform actions directed in an operations abnormal operating procedure. This finding is of very low safety significance because it did not represent an unmonitored release path and there was not an actual release that exceeded regulatory requirements.
