Pilgrim Nuclear Power Station 600 Rocky Hill Road Plymouth, MA 02360-5508 SUBJECT: PILGRIM NUCLEAR POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000293/2009005 AND NOTICE OF VIOLATION
Dear Mr. Bronson:
On December 31,2009, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection alt your Pilgrim Nuclear Power Station (PNPS). The enclosed inspection report documents the results, which were discussed on January 14, 2010, with you and other members of your staff.
The inspection examined activities performed under your license as they relate to safety and compliance with the Commission's rules and regulations. and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, the NRC has determined that a Severity Level IV violation of NRC requirements occurred. The violation was evaluated in accordance with the NRC Enforc:ement Policy included on the !\I RC's Web site at www.nrc.gov; select About NRC, How We Regulate, Enforcement, then Enforcement Policy.
The violation is cited in the enclosed Notice of Violation (Notice) and the circumstances surrounding it are described in detail In the subject Inspection report. During the inspection; the NRC identifIed a violationinvo]vlng Entergy's submittal of inaccurate information to the NRC related to the medical qualifications of licensed operators. Letters to the NRC certified that the operators had been medically examined and had met all medical qualifications, when, In fact, one test (namely, a specific olfactory test) had not been performed. An olfactory test is required to ensure that operators can distinguish among various hazardous odors by smell. Although a test was done for operators to detect tracer gases, a test to detect products of combustion was not performed.
Violations involving the provision of inaccurate or incomplete information are of particular concern to the NRC, and may be considered for escalated enforcement under certain circumstances. However, in this case, the NRC has classified this violation at Severity Level IV, after considering that the inaccurate information did not invalidate the NRC licensing since. all of the operators subsequently passed an olfactory test when Entergy administered it shortly after the NRC identified the violation. Further, the actual and potential safety Significance of this violation was low in that the olfactory test for combustion products was subsequently conducted and successfully passed by each of the licensed individuals. Nonetheless, this violation demonstrates the importance of taking all of the necessary steps and conducting all of the necessary reviews to assure that information submitted to the NRC is complete and accurate in all material respects.
Although this violation has been placed in your corrective action program, a Notice of Violation is being issued and a response is being required to better understand: 1) what actions were taken in 2004 in response to NRC Information Notice (IN) 2004-20, URecent Issues Associated with NRC Medical Requirements for Licensed Operators," which, in part, reminded facility licensees that licensed operators and the personnel who perform and interpret their medical examinations need to be familiar with the regulatory requirements and guidelines (it should be noted that this IN specifically described an instance in which a facility licensee had not conducted some tests required in the ANSI standard for any of its licensed operators); 2) why action was not taken in*
response to IN 2004-20 to assure appropriate olfactory testing was being conducted; and 3) the corrective actions taken and planned at this time to assure all information submitted to the NRC is complete and accurate in all material respects.
You are required to respond to this letter and should follow the instructions specified in the enclosed Notice when preparing your response. The NRC will use your response, in part, to determine whether further enforcement action is necessary to ensure compliance with regulatory requiremen1ts.
Based on the results of this inspection, the NRC has identified one additional issue that was evaluated under the risk Significance determination process as having very low safety significance (Green). The NRC has also determined that a violation is associated with this issue. This violation is being treated as a non-cited violation (NCV), consistent with Section VI.A of the Enforcement Policy. The NCV is described in the subject inspection report. If you contest the violation or significance of the NCV, 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:
(1) the Regional Administrator, Region I; (2) the Director, Office of Enforcement, United States Nuclear Re!~ulatory Commission, Washington, DC 20555-0001; and (3) the Senior Resident Inspector at the PNPS. In addition, if you disagree with the characterization of the finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis fOlr your disagreement, to the Regional Administrator, Region I, and the NRC Senior*
ReSident Inspector at PNPS. The information you provide will be considered in accordance with Inspection Manual Chapter 0305. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice/, a copy of this letter, its enclosures, and your response, will be made available electronically for public inspection in the NRC Public Document Room or from the NRC's document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the public without redaction.

SUMMARY OF FINDINGS
IR 05000293/2009005; 10/01/2009-12131/2009; Pilgrim Nuclear Power Station; Licensed
Operator Requalification; Surveillance Testing The report covered a three-month period of inspection by the resident and region based inspectors. One Significance Level IV cited violation (VIO) and one Green non-cited violation (NCV) was identified. The significance of most findings is indicated by their color (Green, White,
Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP). The cross-cutting aspect for the finding was determined using IMC 0305,
"Operating Reactor Assessment Program." Findings for which the SOP 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 commercial nuclear power reactors is described in NUREG 1649, "Reactor Oversight Process," Revision 4, dated December 2006,
Cornerstone: Mitigating Systems
Severity LevellY. A Severity LevellV violation (VIO) of 10 CFR 50.9, "Completeness and Accuracy of Information," was identified due to the submittal of inaccurate medical information for licensed operators. The submittals to the NRC were inaccurate because they certified that the operators had been medically examined and had met all medical qualifications, when in fact, olfactory testing to detect odor of products of combustion had not been performed. The facility has completed corrective actions to develop and administer an appropriate test. All licensed operators passed this new test, and no new license conditions were required.
The licensee's medical physician failed to adequately test all licensed operators (both initial and renewal licensees) in accordance with 10 CFR 55.21 and 55.33 with respect to ANSIIANS-3.41983. The licensee submitted medical information for its licensed operators and applicants that was incomplete and incorrect in its assessment of the medical condition and general health of its licensed operators and initial applicants. The licensee's failure to provide complete and accurate information to the NRC, which could havH resulted in an incorrect licensing action, is a performance deficiency because the licensee is expected to comply with 10 CFR 50.9, and bec.ause it was within the licensee's ability to foresee and prevent. Because violations of 10 CFR 50.9 are considered to be violations that potentially impede or impact the regulatory process, they are dispositioned using the Traditional Enforcement process. The applicability of cross cutting aspects related to the performance deficiency of this finding will be determined after NRC review of Entergy's response to the Notice of Violation. (Section 1R11)
- Green.
A selfMrevealing, non-cited violation (NCV) of very low safety Significance (Green)of Technical Specification (TS) 5.4.1, "Procedures," was identified for inadequate proc.edural guidance which resulted in repeated lifting of the "A" Standby Liquid Control (SBlC) system relief valve and the subsequent failure of the "A" SBLC system.
Specifically, the SBLC system test procedure did not provide precautions or identify methods to avoid exceeding the pressure set point of the system relief valve during testing. The issue was entered into the corrective action program and the surveillance proc.edure was revised to add cautions against exceeding 1300 psig and to reduce the test pressure window upper limit. In addition. if 1350 psig is exceeded, a condition report must be written to evaluate the impact on the system. Corrective actions are also planned to increase the relief valve design set point and to replace the test throttle valve with one more suited to adjusting system pressure.
The performance deficiency was that Entergy did not specify adequate test controls to ensure that SBLC system relief valve set points were not challenged during tes~
performance. This led to repeated relief valve lifts which over time contributed to the degradation of the relief valve that rendered the "A" SBLC train inoperable. The inspectors determined that the finding was more than minor because the finding was associated with the Procedure Quality attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone's objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences (Le., core damage). Specifically, one train of SBLC was unavailable for several days. Using Inspection Manual Chapter 0609, "Significance Determination Process," Attachment 0609.04. "Phase 1-lnitial Screening and Characterization of Findings," the inspectors determined that the finding is of very low safety significance because it is not a design or qualification deficiency, did not represent a loss of system safety function, did not represent an actual loss of a single train for greater than its TS allowed outage time and was not made risk significant because of external events. This finding has a cross cutting aspect in the Human Performance cross-cutting area, Resources component, because Entergy did not provide complete procedures. Specifically, the procedure did not include precautions and/or techniques to avoid exceeding the relief valve set point during testing. H.2(c) (Section 1R22)

===Seasonal Susceptibilitv
a. Inspection Scope
(1 sample)===
The inspectors reviewed actions taken by Entergy in preparation for the onset of cold weather during the weeks of October 12,19, and 26, 2009. The inspectors reviewed Procedure 8.C.40, Revision 24, "Seasonal Weather Surveillance," and verified that selected steps had been completed. The inspectors walked down selected areas addressed in the procedure to determine if heat tracing as well as plant heating systems were properly aligned. The inspectors also walked down exterior portions of the Fire Water Storage Tanks and the Demineralized Water Storage Tank heating coil valve lineups. The inspectors also reviewed the alignment of the "S" Emergency Diesel Generator (EDG) fire water main heat tracing, and the Technical Support Center EDG sprinkler system heat tracing. The documents reviewed during this inspection are listed in the Attachment.
No findings of significance were identified.
1R04 Equipment Alignment
Partial System Walkdowns (71111.04Q)a.
Inspection Scope (3 samples)
The inspectors performed three partial system walkdowns during this inspection period.
The inspectors reviewed the documents listed in the Attachment to determine the correct system alignment The inspectors performed a partial walkdown of each system to determine if the critical portions of the selected systems were correctly aligned in accordance with these procedures, and to identify any discrepancies that may have had an effect on operability. The walkdowns included selected control switch and valve position checks, and verification of electrical power to critical components. Finally, the inspectors evaluated other elements, such as material condition, housekeeping, and component labeling. The following systems were reviewed based on their risk significance for the given plant configuration:
- K-110 Air Compressor with the K-111 Air Compressor out-of-service;
- "B" Reactor Building Closed Cooling Water (RBCCW) Loop while the "C" RBCCW Pump and the "A" Salt Service Water Pump were out-at-service; and

The inspectors observed licensed operator as-left simulator training on November 12, 2009. The inspectors observed crew response to a loss of coolant accident complicated by a loss of a vital bus. The inspectors assessed the licensed operators' performance to determine if the training evaluators adequately addressed observed deficiencies. The inspectors reviewed the applicable training objectives from the scenario to determine ifthey had been achieved. The inspectors also observed a simulator laboratory demonstration of the effects of various instrument failures. In addition, the inspectors performed a simulator fidelity review to determine if the arrangement of the simulator instrumentation. controls, and tagging closely paralleled that of the control room. The documents reviewed during this inspection are listed in the

.2 Biennial Review - Licensed Operator Regualification Program (71111.11 B)
a. Inspection Scope
(1 sample)
The following inspection activities were performed using NUREG 1021, "Operator licensing Examination Standards for Power Reactors," Rev. 9, Supplement 1, Inspection Procedure Attachment 7111111, "licensed Operator Requaliflcation Program," and 10 CFR Part 55, "Operators' Licenses."
A review was conducted of two years of operating history documentation found in inspection reports, licensee event reports, the licensee's corrective action program, and the most recent NRC plant issues matrix. The inspectors also reviewed specific events from the licensee's corrective action program to evaluate for possible training defil~iencies or appropriate training corrective actions. The resident inspectors were also consulted for insights regarding licensed operators' performance.
Observations were made of the dynamic simulator exams and job performance measures (JPMs) administered during the weeks of October 5 and October 12, 2009.
These observations included facility evaluations of crew and individual performance during the dynamic simulator exams and individual performance of Simulator and in plant JPMs. Four additional weeks of operating examination material administered in 2009 and six weeks of written examinations administered in 2008 were reViewed for compliance with the criteria of the examiner's standards. In addition, written exam grading for the three lowest scoring operators in 2008 was validated.
The remediation plans for one crew failure during the 2009 exam and four individual failures during training sessions were reviewed to assess the effectiveness of the remedial training.
Compliance with operator license conditions was evaluated by reviewing six operator medical records and two years of profiCiency records for six individuals. In addition, reactivation records completed in the last two years were reviewed.
Simulator performance and fidelity were reviewed for conformance to the reference plant control room. Selected simulator deficiency reports were reviewed to assess licensee prioritization and timeliness of resolution. Simulator testing records were reviewed to verify that scheduled tests were performed and deficiencies addressed. Simulator fidelity was observed during simulator scenarios and JPMs. In addition, one plant design change (PDC-98-02) that replaced RHR panel instrumentation was verified to be incorporated into the simulator.
A review was conducted of licensee requalification exam results for the current testing cycl~~. The inspection assessed whether pass rates were consistent with the guidance of the examination standards and NRC Manual Chapter 0609, Appendix I, "Operator Requalification Human Performance Significance Determination Process."
Upon completion of all scheduled examination activities, the inspector reviewed examination results and verified that:
- Crew pass rate was greater than or equal to 80% (Pass rate was 87.5%);
- :Individual pass rate on the dynamic simulator test was greater than 80% (Individual pass rate was 98.1 %.);
- Individual pass rate on the walkthrough (JPMs) was greater than 80% (Pass rate was
'99.2%);
- Individual pass rate on the comprehensive written exam was greater than 80% (No written examination was administered at Pilgrim this year); and
- More than 80% of the individuals passed all portions of the exam (87.5% of the individuals passed all portions of the exam).
b. Findings
===.1
Introduction:
A Severity Level IV violation (VIO) of 10 CFR 50.9, "Completeness and===
Accuracy of Information," was identified due to the submittal of inaccurate medical information for licensed operators. The submittals to the NRC were inaccurate because they certified that the operators h~d been medically examined and had met all medical qualifications, when in fact, olfactory testing to detect odor of products of combustion had not been performed.
Description:
The NRC's requirements related to the conduct and documentation of medical examinations for operators are contained in Subpart C, "Medical ReqUirements,"
of 10 CFR Part 55, Operators' Licenses. Specifically, Section 55.21, "Medical EXclmination," requires every operator to be examined by a physician when he or she first applies for a license, and every two years once receiving their license. The physician must determine whether the operator meets the requirements of Section 55.33(a)( 1), Le.,
the operator's medical condition and general health will not adversely affect the performance of assigned operator duties or cause operational errors that endanger public health and safety.
.
On November 24,2004, the NRC issued Information Notice (IN) 2004-20, "Recent Issues Associated with NRC Medical Requirements for Licensed Operators." The IN communicated that due to recent examples, facility medical requirements may not be receiving sufficient management oversight to ensure that the fitness of licensed operators is being maintained at the required level. The IN also stated that the facility licensee must certify which industry standard (Le., which specific version of ANSIIANS-3.4,. "Medical Certification and Monitoring of Personnel Requiring Operator Licenses for Nu(:lear Power Plants," or other NRC-approved method) was used in making the fitness determination. For this inspection, the 1983 industry standard was required for completion of the medical examination. ANSI-3.41983, Paragraph 5.4.2 "Nose,"
requires licensed operators to have the "ability to detect odor of products of combustion
!*
and of tracer or market gasses."
Durin9 the medical records review, the inspectors determined that the olfactory testing performed by the facility licensee did not meet the ANSI/ANS-3.4 1983 testing requirements. The facility had exclusively tested for tracer gases (natural gas) with the use of a "scratch and sniff' test but had not performed a specific test for products of combustion. The inspectors noted that a checklist used by medical personnel specified "Ability to detect odor of prod ucts of combustion and/or tracer or market gasses."
The failure to perform olfactory testing for products of combustion has the potential to be significant since, during a fire, the operators are required to perform actions to mitigate the effects of a postulated fire. The inability to detect the onset of fire by smelling products of combustion could result in the fire becoming more destructive. It should be noted that most areas of the plant (including control room panels) are equipped with smoke detectors. In this case, all of the operators subsequently passed an olfactory test for products of combustion when Entergy administered it shortly after the NRC identified the violation.
Analysis:
The inspectors determined that a long-standing deficiency had existed at the Pilgrim Nuclear Power Station, in that the licensee's medical physician was not adequately testing all licensed operators (both initial and renewal licensees) in accordance with 10 CFR 55.21 and 55.33 with respect to ANSIIANS-3.4 1983.
10 CFR 55.23 requires that an authorized representative of the facility licensee shall certify the medical fitness of an applicant by completing and signing an NRC Form 396.
NRC Form 396, when signed by an authorized representative of the facility licensee, certifies that a physician conducted a medical examination of the applicant as required in 10 CFR 55.21, and that the guidance contained in ANSIIANS-3.41983 was followed in conducting the examination and making the determination of medical qualification.
The licensee's failure to provide complete and accurate information to the NRC, which could have resulted in an incorrect lioensing action, is a performance deficiency because the licensee is expected to comply with 10 CFR 50.9, and because it was within the licensee's ability to foresee and prevent. Because violations of 10 CFR 50.9 are considered to be violations that potentially impede or impact the regulatory process, they are dispositioned using the Traditional Enforcement process. The finding is more than minor because information was provided to the NRC signed under oath by the company medical doctor and the Site Vice PreSident, which documented that each operator was given a complete examination. There was no evidence that the operators endangered plant operations as a result of inadequate olfactory exams while performing licensed duties. The applicability of cross-cutting aspects related to the performance deficiency of this finding will be determined after NRC review of Entergy's response to the Notice of Violation.
Enforcement:
10 CFR 50.9 states, in part, "Information provided to the Commission by an applicant for a license or by a licensee or information required by statute or by the Commission's regulations, orders, or license conditions to be maintained by the applicant or the licensee shall be complete and accurate in all material respects." Contrary to the above, from April 29, 1999 to October 13, 2009, the licensee submitted inaccurate information to the NRC on NRC Form 396 regarding the medical certification and testing of its licensed operators and initial applicants. This information was material to the NRC because the NRC relied on this certification to determine whether the applicant met the requirements to operate the controls of a nuclear power plant pursuant to 10 CFR Part 55.
The licensee implemented immediate corrective action and satisfactorily performed the required test. The inspectors verified the adequacy and promptness of the licensee's corrective actions for the medical issue. These corrective actions included the development of a smell discrimination test that included products of combustion and tracer gases including natural gas, lemon and lilac. The new tests were administered to all licensed operators and senior licensed operators. All operators passed the test and no new deficiencies were identified. This issue has been entered into the facility corrective action program and is of low safety significance. This violation is being treated com.istent with other licensed operator medical examination findings and the NRC Enforcement Policy.

Introduction:
The inspectors identified an Unresolved Item (URI) involving===
10 CFR 50.59, "Changes, Tests and Experiments," due to a failure to properly implement a procedure change which may have resulted in a "more than minimal increase in the likelihood of occurrence of a malfunction of a structure, system or component (SSC)important to safety...." Pilgrim incorrectly allowed an existing 50.59 evaluation to support a High Pressure Coolant Injection (HPCI) procedure change that allowed actions that were beyond the scope of the existing 50.59 evaluation.
Description:
In February 2000, Pilgrim revised procedure 2.2.21.5, "HPCI Injection and Pressure Control," to provide procedural direction when shutting down the HPCI system.
One of the changes that were made in this revision was the addition of a new section, Section 8, "Preventing HPCllnjection," to the procedure. These changes were evaluated using NOP83E5, "10 CFR 50.59 Process," to evaluate whether this change was allowed a
per '1 CFR 50.59 regulations. Pilgrim concluded that the change to the facility could be made without a safety evaluation or license amendment.
During the performance of a simulator exam scenario, the examiners observed the HPCI system being defeated as drywell pressure approached the automatic initiation setpoint for the HPCI system {2.2 pounds per square inch gage (psig>>. The system was defeated by a Reactor Operator placing the HPCI oil pump in Pull-to-Lock (PTL). This action prevents HPCI from starting in response to Emergency Safeguards Feature (ESF)automatic initiation signals. The order to defeat HPCI was made before the automatic initiation setpoint was reached, which is also the required entry into the Emergency Operating Procedures (EOPs). The examiners requested the procedural guidance that directed this action, since the Emergency Operating Procedures (EOPs) had not yet been entered when HPCI was defeated. The examiners reviewed the revised procedure as well as the procedure change paperwork and 50.59 preliminary evaluation checklist developed to support the revised procedure.
The examiners concluded that the 50.59 preliminary evaluation checklist developed to support the revision to procedure 2.2.21.5 was incorrect and did not support the proc:edure revision. The basis for the procedure change was:
"to provide enhanced instructions for the operation of the HPCI System under various emergency operating modes. Several of these operations, such as pressure control and placing HPCI to 'inhibit'are required to be performed during the execution of various EOPs. These evolutions are analyzed in Emergency Procedure Guidelines (EPGs) Rev. 4 and have been approved by the NRC per SER # 1.88.196."
Since the procedure change can be used outside the EOPs, the EPGs and SER No. 1.88.196 do not fully support the conditions under which the HPCI system may be secured. Therefore, the 50.59 preliminary evaluation checklist was incorrect, and a separate safety evaluation was required to allow the HPCI system to be secured ,outside the EOPs. This issue remains unresolved until the facility completes their development of a new safety evaluation to determine whether prior NRC's approval would have been required before implementing the described procedure change.

.2 Failure of the "A" Standby Liquid Control Train, URI 05000293/2009004-03 (Closed)
a. Inspection Scope
On July 10, 2009, the "A" Standby Liquid Control (SBlC) train failed during the quarterly surveillance test. The inspectors opened an Unresolved Item (URI) in Pilgrim Integrated Inspection Report 2009004 pending Entergy's review of the apparent causes. The inspectors reviewed additional information documented in the condition report and discussed it with plant staff in order to determine whether or not a performance deficiency existed.
b. Findings
Introduction:
A self-revealing, non-cited violation (NCV) of very low safety significance (Green) of Technical SpeCification (TS) 5.4.1, "Procedures," was identified for inadequate procedural guidance which resulted in repeated lifting of the ~A" Standby Liquid Control (SBlC) system relief valve and the subsequent failure of the uN' SBlC system.
SpeCifically. the SBlC system test procedure did not provide precautions or identify methods to avoid exceeding the pressure set point of the system relief valve during testing.
Description:
On July 10, 2009. during the quarterlY surveillance on the "A" SBlC train, the system relief valve, PSV-11 05A. lifted and did not reseat, which diverted flow such that the system could not meet its TS acceptance criteria. During the performance of the surv'eillance, operators adjust the test throttle valve while the pump is running to achieve a test pressure between 1275 and 1300 psig. Entergy determined that the test throttle valve is not well-suited for throttling at those pressures. In addition, the targeted pressure band is close to the relief set point of the valve, the positive displacement pump design causes pressure perturbations in the system during throttle valve manipulation, and the operators have a very limited amount of time to achieve the test pressure due to a small test tank volume. The system test procedure does not provide precautions or other methods to limit the aggregate impact of these system limitations. As a result. the pressure set point of the relief valve has historically been exceeded. The relief valv~ is not designed to lift during normal system operation and Entergy concluded that repeated lifting during testing contributed to wear on the valve and its subsequent failure. The train was declared inoperable, the relief valve was replaced, and the system was restored to service onJuly 12,2009.
This issue has been entered into Pilgrim's corrective action program and the surveillance procedure has been revised to add a requirement for operators to write a condition report if SBLC system pressure exceeds 1350 psig during performance of the test. In addition, the test pressure window has been narrowed to 1275-1290 psig, and a caution has been added to the procedure to avoid exceeding 1300 psig while operating the test throttle valve. Long term corrective actions include increasing the design set point of the relief valve and replacing the test throttle valve with one more suited to adjusting system pressure.
Analysis:
The performance deficiency was that Entergy did not specify adequate test controls in their test procedure to ensure that SBLC system relief valve set points were not challenged during test performance. This issue was within Entergy's ability to foresee and correct and should have been prevented. This led to repeated relief valve lifts which over time contributed to the degradation of the relief valve that rendered the "A" train inoperable. Traditional Enforcement did not apply, as the issue did not have actual or potential safety consequence, had no willful aspects, nor did it impact the NRC's ability to perform its regulatory function. The inspectors determined that the finding was more than minor because the finding was associated with the Procedure Quality attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone's objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences (Le., core damage). Specifically, one train of SBLC was unavailable for several days.
A review of NRC Inspection Manual Chapter (IMC) 0612, Appendix E, "Minor Examples,"
revealed that no minor examples were applicable to this finding. The inspectors determined the significance of the finding using IMC 0609.04, "Phase 1 - Initial ScrE~ening and Characterization of Findings." The finding was determined to be of very low safety significance (Green) because the finding did not involve a design or qualification deficiency resulting in loss of operability or functionality, did not result in a loss of system safety function, and did not screen as potentially risk significant due to external initiating events.
This finding has a cross~cutting aspect in the Human Performance cross-cutting area, Resources component, because Entergy did not provide complete procedures.
Specifically, the procedure did not include precautions and/or techniques to avoid exceeding the relief valve set point during testing. H.2(c)
Enforcement:
TS 5.4.1.a, "Procedures," requires that written procedures be maintained as recommended in NRC Regulatory Guide (RG) 1.33, Revision 2, Appendix A, February 1978. RG 1.33, Appendix A, Section 8b includes procedures for surveillance tests for the "Liquid Poison System." Contrary to the above, Procedure 8.4.1, Revision 68, "Standby Liquid Control Pump Quarterly and Biennial Capacity and Flow Rate Test," was not appropriately maintained in that it did not include adequate precautions or methods to avoid exceeding the system relief valve lift pressure set point when throttling to achieve test pressure. This led to repeated relief valve lifts which contributed to the degradation of the relief valve that eventually rendered the "A" SBlC train inoperable. Corrective actions include revising the surveillance procedure to add cautions against exceeding 1300 psig and to reduce the test pressure window upper limit. In addition, jf 1350 psig is exceeded, a condition report must be written. Entergy has also planned corrective actions to increase the relief valve design set point and to replace the test throttle valve with one more suited to adjusting system pressure. Because this finding is of very low safety significance and Entergy has entered it into their corrective action program (CR PNP-2009-3088), this violation is being treated as an NCV, consistent with Section VI.A 1 of the NRC Enforcement Policy.

1EP3 EmE~rgency Response Organization Staffing and Augmentation System
a. Inspection Scope
(1 sample)
The inspectors performed a review of Pilgrim's ERO augmentation staffing requirements and the process for notifying and augmenting the ERO. This was performed to ensure the readiness of key Entergy staff to respond to an emergency event, and to ensure*
Entergy's ability to activate their emergency facilities in a timely manner. The inspectors reviewed the Pilgrim ERO roster, training records, applicable procedures, drill reports for augmentation, quarterly EP drill reports, and CRs related to the ERO staffing augmentation system. The inspection was performed in accordance with NRC Inspection Procedure 71114.03. Planning Standard 10 CFR 50.47(b )(2) and related requirements of 10 CFR 50, Appendix E, were used as reference criteria.
b. Findings
No findings of significance were identified.
1EP4 Emergency Action Level (EAl) and Emergency Plan Changes
a. Inspection Scope
(1 sample)
Since the last NRC inspection of this program area in April 2008, Entergy had implemented various revisions of the different sections of the Pilgrim Nuclear Power Station Emergency Plan. Entergy had determined that, in accordance with 10 CFR 50.S4(q), any change made to the Plan, and its lower-tier implementing procedures, had not resulted in any decrease in effectiveness of the Plan, and that the revised Plan continued to meet the requirements of 10 CFR S0.47(b) and Appendix E to 10 CFR 50.
The inspectors reviewed all EAL changes that had been made since April 2008, and performed a sampling review of other Emergency Plan changes, including the changes to lower-tier emergency plan implementing procedures, to evaluate for any potential decreases in effectiveness of the Emergency Plan. However, this review was not documented in an NRC Safety Evaluation Report and does not constitute formal NRC approval of the changes. Therefore, these changes remain subject to future NRC inspection in their entirety. The inspection was performed in accordance with NRC Inspection Procedure 71114.04. The requirements in 10 CFR 50.54(q) were used as reference criteria.
b. Findings
No findings of significance were identified.

a. Inspection Scope
The inspectors performed a screening of each item entered into Entergy's CAP. This review was accomplished by reviewing printouts of each Condition Report (CR),attending daily screening meetings and/or acceSSing Entergy's database. The purpose of this review was to identify conditions such as repetitive equipment failures or human*
performance issues that might warrant additional follow-up.
No findings of significance were identified .
.2 Semi-Annual Review to Identify Trends:
a. Inspection Scope
(1 sample)
The inspectors performed a review of Entergy's Corrective Action Program (CAP) and associated documents to identify trends that could indicate the existence of a more significant safety issue. The review was focused on repetitive equipment and corrective maintenance issues, but also considered the results of daily inspector CAP item screening. The review included issues documented in CAP trend reports and the site CAP performance indicator data. The review focused on the six month period of July 2009, through December 2009, although the inspectors also evaluated previous trend results for CRs from December 2008, through June 2009, which were discussed in Pilgrim Integrated Inspection Report 2009003. The documents reviewed during the inspection are listed in the Attachment.
b. Findings and Observations
No findings of Significance were identified. Two low level trends discussed in Pilgrim Integrated Inspection Report 2009003 were reviewed and are discussed below. No additional low level trends were identified by the inspectors during this time period.
Post Maintenance Modification Testing The inspectors reviewed CR-PNP-2009-2778, which was written to perfonn an assessment of post maintenance test activities documented at Pilgrim during and since Pilgrim's refueling outage (RF017). The inspectors performed additional post maintenance test inspection samples and continued to monitor post-maintenance test issues during the last two quarters of 2009. During the past two quarters the inspectors continued to identify deficiencies in post maintenance testing. Examples included 1)review of a work package by the inspectors determined that acceptance criteria for a control rod drive pump had not been met; and 2) inspector review of a Station Blackout EDG post-maintenance test identified a value for the air cleaner differential pressure which was outside of its specified range with no condition report or other assessment of acceptability documented in the work package. Due to the identification of continued deficiencies and because corrective actions to improve post maintenance testing at Pilgrim have not been in effect long enough to conclude whether they have been effective, the inspectors will continue to monitor this trend during the next two quarters.
Temporary Modification Controls The inspectors reviewed CR-PNP-2009-3064, which was written to perfonn an assessment of temporary modification issues documented at Pilgrim since January 2008.
The inspectors also performed additional temporary modification inspection samples.
The inspectors determined that Entergy has performed an in-depth review of temporary i
I modification program administration issues. This review identified a significant number of procedures which were revised to include specific requirements for the documentation of activities associated with temporary modifications. Entergy also conducted training for shift managers in their responsibilities during the implementation of the temporary modification process. In addition, Entergy has implemented process changes for the replacement of control room drawings and alarm response procedures to preclude the inadvertent removal of temporary modification tags. The inspectors have determined that the above actions should be effective in improving the administration of the temporary modification program and consider this low level trend closed .
.3 Annual Sample: Failure of Secondary Containment Damper
a. Inspection Scope
(1 sample)
This inspection focused on Entergy's identification, evaluation, and resolution of deficiencies associated with the failure of a secondary containment damper as documented in Licensee Event Report (LER) 2008-001, CR-PNP-2008-0140 and CR PNP*2008-0143. Specifically, on January 10, 2008, a secondary containment damper, AO-N-78, did not go full closed during online cycling performed as part of damper preventative maintenance. On January 14, 2008, during the work order review process, it was noted that the damper had not met the acceptance' criteria of the maintenance procedure, and thus should have been immediately closed to maintain secondary containment integrity. Subsequent to this discovery, secondary containment was declared inoperable, and the a~sociated Limiting Condition for Operation (LCO) action statement was entered. The associated in-line damper, AO-N-79, was closed, the maintenance procedure was re-performed on AO-N-78, and all acceptance criteriawere met. Damper AO-N-78 was then determined to be operable and the LCO for Secondary Containment operability was exited.
The inspectors reviewed Entergy's associated apparent cause analysis, extent-of condition review, identification of compensatory actions, and the short and long-term corrective actions associated with the damper failure to determine if Entergy had corrective actions in place commensurate with the. safety significance of the issue. The I
inspectors reviewed condition reports written for previous secondary containment damper failures, historical work orders, leak rate test trending, and the applicable maintenance rule basis document to evaluate past performance of the dampers and to determine if Entergy had properly identified and corrected conditions adverse to quality.
The inspectors interviewed the system engineer and licensed operators, and reviewed plant procedures, related industry operating experience, and preventative maintenance schedules to verify Entergy's ability to adequately monitor damper performance in order to identify damper degradation and assess the adequacy of their maintenance program as it pertains to maintaining the operability of safety related structures, systems and components (SSCs). The documents reviewed during the inspection are listed in the
.
.
b. Findings and Observations
No findings of significance were identified. While reviewing condition reports written for secondary containment damper failures prior to 2008, the inspectors determined that Entergy's use of a category level D (Administrative Closure) CR was not in accordance with the site-assigned categorization levels as described in Attachment 9.1 of procedure EN-Ll-102, "Corrective Action Process." Specifically, the inspectors identified that CR PNP-2007-1172, pertaining to three secondary containment damper failures (AO-N-78, AO-N-79, and AO-N-80) in April 2007, documented a condition adverse to quality related to TS-related equipment without sufficient CR supporting documentation that would allow Entergy personnel to support a level D categorization in accordance with EN-U-102. The inspectors' review determined that a level C (Non-significant Correction Only)categorization would typicaJly ensure higher management visibility, more timely corrective actions, and more thorough documentation of corrective actions, including final closure documentation to ensure damper operability and TS implications were fully addressed.
Specifically, the corrective action to re-inspect and cycle the secondary containment dampers as a follow-up to CR-PNP-2007-1172 was not completed until January 10, 2008, at which time damper AO-N-78 again did notfully close. The failure of AO-N-78 to fully close was not reported to Operations until January 14, 2008, at which time secondary containment was declared Inoperable. CR-PNP-2008-0143 documented an apparent cause for the delay in notifying Operations of the problem with the AO-N-78 damper not going completely closed. The documented apparent cause included unclear
. damper seal inspection acceptance criteria and a mindset that since the damper was previously found not able to fully close but was still considered operable in 2007, the present condition in 2008 was also acceptable. Entergy has taken additional corrective action to address these issues.
The inspectors also noted that Entergy's maintenance rule program does not provide clear documented guidance for determining maintenance rule functional failures for secondary containment dampers. Additionally, the maintenance rule bases document applicable to secondary containment covers all heating, ventilation, and air conditioning (HVAC) systems and includes 14 maintenance rule functions, only some of which are safety-related. The inspectors determined that the vague nature of the maintenance rule program, as it pertains to secondary containment, makes it difficult for Entergy to monitor the performance and condition of the dampers in a manner sufficient to provide reasonable assurance that these SSCs are capable of fulfilling their intended functions.
This issue was captured in Entergy's corrective action program as part of CR-PNP-2009 419i' .
.4 Annual Sample: Foreign Material Exclusion (FME) Events during RFO 17
a.
InsQ.ection Scope (1 sample)
This inspection focused on Entergy's identification, evaluation, and resolution of deficiencies associated with foreign material exclusion events that occurred during the 2009 Refueling Outage, as documented in CR-PNP-2009-1467, CR-PNP-2009-1503, CR-PNP-2009-1614, CR-PNP-2009-1767, CR-PNP-2009-1778, CR-PNP-2009-1812, CR-PNP-2009-1850, and CR-PNP-2009-2002.
The inspectors reviewed Entergy's associated apparent cause analysis, extent-of condition review, identification of compensatory actions, and the short-term and long term corrective actions associated with the FME events to determine if Entergy had corrective actions in place commensurate with the safety significance of the issues. The I
i inspectors reviewed site and corporate procedures and interviewed the site FME Coordinator and Outage Manager to assess timeliness of Entergy's assimilation of I outage lessons learned specific to the FME program. The inspectors also utilized these interviews, along with a review of a vendor report that tracked FME issues during the I outage, to assess Entergy's coordination of long-term and short-term corrective actions with vendors and contractors involved in a large number of the FME events that occurred during the outage. The inspectors reviewed operability determinations and engineering evaluations performed following the FME events to verify that, in developing corrective actions for each event, Entergy adequately evaluated potential impacts of the FME on core and safety related equipment performance. The documents reviewed in the inspection are listed in the Attachment.
b. Findings and Observations
No findings of significance were identified. The inspectors determined that Entergy's corrective actions were reasonable with respect to the FME events that occurred during RFO 17. The CR packages varied in composition based on specific FME issues, but in general included an initial apparent cause evaluation, extent-at-condition reviews, completed corrective actions. planned corrective actions, and compensatory actions.
The inspectors concluded that the elements of the CR packages were detailed and thorough and the proposed corrective actions were adequate to address deficiencies identified. The inspectors concluded that the long-term corrective actions in place to evaluate the RFO 17 FME events in the aggregate, while incorporating the RFO 17 lessons learned into their FME program. were adequate. Additionally, the inspectors determined that Entergy's coordination of corrective actions with vendors and contractors involved in the subject FME events was adequate.
