SUMMARY OF FINDINGS
tR 05000227t2011005, 0500027812011005; 1010112011 - 1213112011; Peach Bottom AtomicPower Station (PBAPS), Units 2 and 3; Maintenance Effectiveness and Radioactive Gaseousand Liquid Effluent Treatment.The report covered a three-month period of inspection by resident inspectors and announcedinspeciions performed by regional inspectors. One self-revealing (Green) finding and oneinspector-identified finding were identified. The significance of most findings is indicated by theircolor (Green, White, Yellow, or Red) using Inspection Manual Chapter (lMC) 0609, "SignificanceDetermination Process" (SDP). The cross-cutting aspect associated with the findings wasdetermined using IMC 0310, "Components Within the Cross-Cutting Areas." Findings forwhichthe SDP does not apply may be Green, or be assigned a severity level after NRC managementreview. The NRC's program for overseeing the safe operation of commercial nuclear powerreactors is describeO inNUREG-1649, "Reactor Oversight Process," Revision 4, datedDecember 2006.Cornerstones: Initiating Events, Mitigating Systems, and Barrier lntegrityGreen. The inspectors determined that Exelon's failure to promptly correct a conditionaOverse to quality associated with a safety-related motor-operated valve (MOV)constituted a Green, self-revealing NCV of 10 CFR Part 50, Appendix B, Criterion XVl,"Corrective Action." Specifically, corrective actions to prevent recurrence of MOVprogram testing failures due to degraded stem lubrication in 2009 were not performed ina timely manner to prevent the inoperability of a safety-related MOV due to degradedlubricaiion, as identified on September 22,2011. PBAPS entered this issue into theCAP via issue reports (lRs) 1266600 and 1266604'This finding was more than minor because it was associated with the configurationcontrol attribute of the Barrier Integrity (Bl) cornerstone and affected the cornerstoneobjective of providing reasonable assurance that physical design barriers protect thepu-Oti" from iadionuciide releases caused by accidents or events. Specifically, the Unit 3reactor water cleanup (RWCU) outboard isolation valve MO-3-12-018 did not developsufficient thrust at the torque switch trip setpoint during diagnostic testing on September22, 2011. The RWCU MOV would not have been able to perform its safety function toclose during the most limiting design condition. Using the Phase '1 worksheet inAppendix a of IMC 0609, "SDP," the finding affected the Bl cornerstone and was of verylow safety significance (Green) because it did not represent an actual open pathway inthe physical integrity of containment.This finding had a cross-cutting aspect in the area of Problem ldentification & Resolution(pl&R), CAP, because Exelon did not take appropriate corrective actions to address theadverse trend of degraded stem lubrication on a safety-related MOV in a timely manner(Section 1 R12) IP.1(d)1.
Cornerstone: Public Radiation Safety
- Green.
The inspectors identified a Green finding associated with the failure to establish,imptement, and maintain adequate quality assurance (QA) program elements in the areaEnclosure 4of effluent and environmental monitoring as required by Peach Bottom, Units 2 and 3Technical Specification (TS), Section 5.4.1. Specifically, Exelon's QA program foreffluent and environmental monitoring was not sufficient to ensure: 1) that bothadequate and timely evaluation and assessment of changes described in the PublicLand Use Census were conducted for purposes of dose validation and samplingprogram modification; 2) that changes in meteorological parameters, used for publicdose projections and assessment, were promptly and adequately evaluated; and 3) thatlaboratory QA programs for effluent and environmental sample analysis measurementsystems were adequate and implemented properly. Exelon placed thes_e issues in itsinp as Action Requests (ARs): 1226969, 1226202,1299543, 1299476,1302720, and1303308.The finding is more than minor because it is associated with the Public Radiation Safetycornerstone attribute of programs and processes and adversely affected the associatedcornerstone objective in that failure to establish, implement, and maintain an adequateQA program in the effluents and environmental monitoring program area adverselyaffected the licensee's ability to ensure adequate protection of public health and safety.The finding was assessed for significance using IMC 0609, Appendix D, and determinedto be of very tow safety significance (Green) because: the issue was contrary to TSsand is a radioactive effluent release program deficiency; there was no indication of a spillor release of radioactive material on the licensee's site or to the offsite environs thatwould impact public dose assessment, and there was no substantialfailure to implementthe radioactive effluent release program. The licensee re-assessed the dose tomembers of the public from routine releases and determined that projected doses didnot, nor were likely to, exceed applicable limits, including as low as is reasonablyachievable (ALARA) design specifications of 10 CFR Part 50, Appendix l; or 10 CFR20.1301(e). The cause of this finding is related to the cross-cutting area of HumanPerformance, Work Practices, Aspect H.4(b) because the licensee did not ensurepersonnelfollowed procedure compliance requirements activities for effluent andenvironmental monitoring program. (Section 2RS06) tH.4(b)1.
Other Findings
Two violations of very low safety significance, which were identified by the licensee, have beenreviewed by the inspectors.' CoireCtive actions taken or planned by Exelon have been enteredinto the CAp. Tnese violations and the corrective action tracking numbers are listed in Section4OA7 of this report.Enclosure 5

Inspection ScopeThe inspectors reviewed the samples listed below to assess the effectiveness ofmaintenance activities on structures, systems, and components (SSCs) performanceand reliability. The inspectors reviewed system health reports, CAP documents,maintenance WOs, and maintenance rule (MR) basis documents to ensure that PBAPSwas identifying and properly evaluating performance problems ryitJ,f the scope of theMR. For "".lirarple seletted, the inspectors verified that the SSC was properlyscoped into the MR in accordance with 10 CFR 50.65 and verified that the (aX2)performance criteria established by PBAPS staff was reasonable. As applicable, forSSCs classified as (a)(1), the inspectors assessed the adequacy of goals and correctiveactions to return tnese'SSCs to (a)(2). Additionally, the inspectors ensured that PBAPSstaff was identifying and addressing common cause failures that occurred within andacross MR system boundaries.o Unit 3 RWCU system leaks on October 16 and 22,2011o Unit 3 RWCU outboard isolation MOV diagnostic testing failure and degradedlubrication on November 14, 15, and 21 , 2011b. FindinqsIntroduction. The inspectors determined that Exelon's failure to promptly correct acondition adverse to quality associated with a safety-related MOV constituted a Green,self-revealing NCV of 'tO ifn 50, Appendix B, Criterion XVl, "Corrective Action."Speci1cally, iorrective actions to prevent recurrence of MOV program testing failuresdue to degraded stem lubrication in 2009 were not performed in a timely manner toprevent thL inoperability of a safety-related MOV due to degraded lubrication, asidentified on SePtember 22.Description. During as-found diagnostic testing performed by Exelon on September 22,the unit 3 RWCU o-utboard Mov Mo-3-12-018 did not develop sufficient thrust at thetorque switch trip setpoint to ensure that the valve would close under the most limitingdesign basis differeniial pressure scenario. Subsequent inspeclionby Exelonmaintenance personnel determined that the MOV stem lubrication, Exxon Nebula EP-1'was dry and caked on the valve stem with no functioning lubricant on the stem threads.pBApS determined that the cause of the underthrust condition was attributed todegraded stem lubrication and the resultant increased coefficient of friction on the valveEnclosure
9stem. lmmediate corrective actions included cleaning and removing the Nebula EP-1grease, applying MOV Long-Life grease to the valve stem, and performing successfulIs-left diagnostic testing. PBAPS-'s extent-of-condition (EOC) efforts are summarized inthe last paragraph of the "Description" section of this finding'pBApS root cause evaluation report 892191-08 determined that degraded MOV stemlubrication resulted in four safety-related MOV program test failures in March and April of2009. pBAPS performed multiple corrective actions to address the 2009 MOV programtesting failures, as well as an EOC scoping that included inspection, diagnostic testing,and/oi corrective maintenance on 45 safety-related MOVs in March and April of 2009.Additional corrective actions included revising MOV program procedures and preventivemaintenance (PM) frequencies. PBAPS also identified degraded Nebula EP-1 greaseon MOV program valves in 2006, 2007, and 2008, as discussed in root cause evaluationieport Agbt g-1-Oe, Attachment 1 . The root cause evaluation identified that PBAPS hadthe longest allowable MOV PM lubrication intervals (10 years) in the United Statesnuclear-industry. Another factor related to MOV stem lubrication, the vendor cancelledproduction of lriebula EP-1 in 2001, stating a one-ye_ar limited shelf life. Additionally,Lxelon internal operating experience identified a MOV test failure due to degraded stemlubrication at Braidwood on June 21 ,2010. As a result of the PBAPS and Braidwooddegraded MOV grease events, Exelon has initiated corporate actions to transition allsites from Nebula EP-1 to MOV Long-Life by the end of 2014'Root cause evaluation report 892191-08 required changing the MOV stem lubricantto MOV Long-Life grease as a corrective action to prevent recurrence of MOV programtesting failures Oue to degraded stem lubrication. PBAPS implemented a risk-informedif ign,heOium and tow riif) corrective action plan based on the level of susceptibility toOelraOeO stem lubrication. RWCU outboard isolation valve MO-3-12-018 was includedin iire ',medium," risk population of MOV program valves that had not yet been convertedto MOV Long-Life grease at the time of the diagnostic test_failure on September 22.MO-3-1 Z-}1-Bwas scheduled for PM and conversion to MOV Long-Life following as-found diagnostic testing, which constituted a six-year PM interval. PBAPS identified thatthe MOV program scofing for MO-3-12-018 did not include the correct high temperaturestem factor, wnicn would have reduced the PM frequency to four years'At the close of the inspection period, PBAPS had transitioned 128 of the 182 MOVprogram valves to MdV Long-111" grease. In addition to the previously discussedcoriective actions in responsl to thl Mo-3-12-018 degraded grease, PBAPS.performedan EOC review of all MOVs that have not yet been converted to MOV Long-Life grease,including MOV program calculations to identify additional errors such as theaforeme-ntioneO nign temperature stem factor on MO-3-12-018. Field walkdowns werealso performed onlll Unit g MOVs with NebulaEP-1grease, as well as all accessibleUnit 2 MOVs with Nebula EP-1 grease. Based on the EOC review, 14 MOVs had theirgrease conversion dates moved fonrvard. Additionally, PBAPS has expedited correctiveIctions to complete the MOV Long-Life conversion on all MOV program valves fromDecember 2O14to December 2013. The NRC inspectors reviewed the final EOCscoping and determination performed by PBAPS, and found that it was appropriate tothe circumstances.Analvsis. The inspectors determined that Exelon's failure to promptly correct a conditionlEffito quality associated with a safety-related MOV constitutes a performanceJ"ti"i"n.y. 'speiiticatty, degraded Exxon Nebula EP-1 stem lubricant caused RWCUEnclosure 10outboard isolation valve MO-3-12-018 to fail diagnostic testing on September 22,2011,after a root cause evaluation required changing the stem lubricant to MOV Long-Lifegrease to prevent recurrence of multiple safety-related MOV diagnostic testing failures inMarch and April of 2009. This finding was more than minor because it was associatedwith the containment configuration control attribute of the Barrier Integrity cornerstoneand affected the cornerstone objective of providing reasonable assurance that physicaldesign barriers protect the public from radionuclide releases caused by accidents orevents. Specifically, the RWCU outboard isolation valve MO-3-12-018 did not developsufficient thrust at the torque switch trip setpoint during diagnostic testing on September22,2011, and therefore would not have been able to perform its safety function to closeduring the most limiting design condition. Using the Phase 1 worksheet in Attachment 4of IMC 0609, "SDP," the inspectors determined that this finding was of very low safetysignificance (Green) because it did not represent an actual open pathway in the physicalintegrity of reactor containment.This finding had a cross-cutting aspect in the area of Pl&R, CAP, because Exelon didnot take appropriate corrective actions to address a safety issue in a timely mannerlP.1(d)]. Specifically, Exelon failed to address the adverse trend of degraded MOV stemlubricant in a timely manner, which resulted in loss of the RWCU outboard isolation valveclosing safety function for the most limiting design condition.Enforcement. 10 CFR 50, Appendix B, Criterion XVl, "Corrective Action," states, in part,that measures shall be established to assure that conditions adverse to quality arepromptly identified and corrected. Contrary to the above, Exelon failed to promptlycorrect a condition adverse to quality associated with degraded stem lubrication onRWCU outboard isolation valve MO-3-12-018. Specifically, root cause evaluation892191-08 required Exelon to change MOV stem lubrication from Nebula EP-1 to MOVLong-Life, as a corrective action to prevent recurrence of multiple MOV program testingfailures due to degraded stem lubrication identified in 2009. As a consequence ofExelon's failure to promptly correct this condition adverse to quality, MO-3-12-018 faileddiagnostic testing due to degraded Nebula EP-1 stem lubrication on September 22,2011. Because this finding is of very low safety significance and has been entered intothe CAP via lRs 1266600 and 1266604, this violation is being treated as a Green NCVconsistent with the NRC Enforcement Policy.

Inspection ScopeThe inspectors reviewed station evaluation and management of plant risk for themaintenance and emergent work activities listed below to verify that PBAPSperformed the appropriate risk assessments prior to removing equipment for work. Theinspectors selected these activities based on potential risk significance relative to theReactor Safety cornerstone. As applicable for each activity, the inspectors verified thatPBAPS personnel performed risk assessments as required by 10 CFR 50.65(aX4) andthat the assessments were accurate and complete. When PBAPS performed emergentwork, the inspectors verified that operations personnel promptly assessed and managedplant risk. The inspectors reviewed the scope of maintenance work and discussed theresults of the assessment with the station's probabilistic risk analyst to verify plantconditions were consistent with the risk assessment. The inspectors also reviewed theEnclosure l1TS requirements and inspected portions of redundant safety systems, when applicable,to veriiy risk analysis assumptions were valid and applicable requirements were met..

Unit 3 SLC tank temperature control degraded equipment on November 15,2Q11o primary containment overpressure credit for emergency core cooling pumps onNovember 23 and 29,2011The inspectors selected these issues based on the risk significance of the associatedcomponents and systems. The inspectors evaluated the technical adequacy of theoperability determihations to assess whether TS operability was properly justified andthe subject component or system remained available such that no unrecognizedincrease in risk occurred. The inspectors compared the operability and design criteria inthe appropriate sections of the TSs and UFSAR to PBAPS's evaluations to determinewhether the components or systems were operable. Where compensatory measureswere required to maintain operability, the inspectors determined whether the measuresin place would function as intended and were properly controlled by PBAPS' Theinspectors determined, where appropriate, compliance with bounding limitationsassociated with the evaluations.b. FindinqsNo findings were identified.1 R18 Plant Modifications (71111.18 - 1 sample)Permanent Mod ifications10,2011regulator malfunction and emergentEnclosure 12a. Inspection ScoPeThe inspectors evaluated the permanent modification to the Multiple Spurious OperationMotor Control Center Breaker implemented by Engineering Change Request (ECR) 10-OO44g, "Multiple Spurious Operation Motor Control Center Breaker Rework" onNovember 1d and 17. The inspectors verified that the design bases, licensing bases,and performance capability of the affected systems were not degraded by themodification. In addition, the inspectors reviewed modification documents associatedwith the upgrade and design change, which included 10 CFR Part 50.59 documentationand post-mbdification testing resulis. The inspectors also conducted field walkdowns ofthe modifications to verify that the temporary modifications did not degrade the designbases, licensing bases, and performance capability of the affected systems.b. FindinqsNo findings were identified.
1R19 Post-Maintenance Testinq (71111.19 - 8 samples)a. Inspection ScopeThe inspectors reviewed the post-maintenance tests (PMTs) for the maintenanceactivities listed below to verify that procedures and test activities ensured systemoperability and functional capability. The inspectors reviewed the test procedure toverify tnai tne procedure adequately tested the safety functions that may have beenaffeited by the maintenance activity, that the acceptance criteria in the procedure wasconsistenfwith the information in the applicable licensing basis and/or design basisdocuments, and that the procedure had been properly reviewed and approved. Theinspectors also witnessed the test or reviewed test data to verify that the test resultsadequately demonstrated restoration of the affected safety functions..

The inspectors discussed correctiveactions-for identified concerns with Exelon personnel'Findinoslntroduction. The inspectors identified a Green Finding associated with failure toestabl'Sh, 'rnplement, and maintain adequate QA program elements in the area ofeffluent and environmental monitoring as required by Peach Bottom Units 2 and 3TSs Sectio n 5.4.1.c, "Quality assurance for effluent and environmental monitoring."Specifically, Exelonjs QA program for effluent and environmental monitoring was notsufficient to ensure: 1) that Ootfr adequate and timely evaluation and assessment of.h"ngur described in ifre 2010 Public Land Use Census were conducted for purposes ofdose validation and sampling program modification; 2) that changes in meteorologicalfarameters, used for public Oose prolections and assessment, were promptly andEnclosure
22adequately evaluated; and 3) that laboratory quality assurance programs for effluent andenviionmental sample analysis measurement systems were adequate and implementedproperly.Description. Peach Bottom Units 2 and 3 TSs require in Section 5.4.1.c, among otherrequtrements, that QA procedures for effluent and environmental monitoring beestablished, implemented, and maintained'Exelon established various effluent and environmental monitoring QA programprocedures to provide QA for important elements of the effluent and environmentalmonitoring program that could collectively and individually impact public dose projectionsattributable to effluent releases from the Peach Bottom Station. These QA elementscovered such matters as: 1) evaluation of public land use around the station to ensuredose pathway analyses were conducted taking into consideration current land usearound the facility; 2) evaluation of changes to important meteorological parametersused for public dose'projection; and 3) various laboratory QA program elements toprovide assurance that onsite and vendor laboratories were providing acceptableanalytical results. The inspectors identified six examples where the effluent andenvironmental QA program was ineffective as follows:. Exelon did not conduct an evaluation of its 2010 Land Use Census results inaccordance with Procedure CY-AA-1 70-1 000, Revision 5, "RadiologicalEnvironmental Monitoring Program and Meteorological Program lmplementation."The evaluation supports tfre Oetermination, from a QA perspective, of the need foradditional new monitoring stations (compensatory measures) based on changes inthe land use and calculaied dose or dose commitment. Procedure CY-AA-170-1000required in section 4.5, that the census be reviewed against the requirements listedin ine station's ODCM, and the ODCM required that compensatory measures betaken to add new environmental monitoring locations, within 31 days, if needed'Exelon had completed its 2010 Land Use Census (dated January 4, 2011) for PeachBottom and provided a summary of the census to the NRC in its May 31,2011'Annual Radiological Operating Report (No. 63). Exelon subsequently conducted anevaluation of the 2010 Land Use Census in July 2011, which included newinformation, and concluded no change in monitoring was required. Exelon placedthis issue into its CAP (AR 1226969)'. Exelon did not conduct an assessment of its long term meteorological data tocompare the 2010 annual meteorology values of )UQ (dispersion factor) and D/Q(deposition factor) against long term averages to determine if non-conservativeirends existed. Exel6n Procedure CY-AA-170-1000, Revision 5, "RadiologicalEnvironmental Monitoring Program and Meteorological Program lmplementation,"required in Section +.0.+ltnatihe annual meteorologicalXQ (dispersion) and D/Q(deposition) values be compared to the long term historical X/Q and D/Q values forsignificant changes in a non-conservative direction. The procedure required that ifthe values were-found to be trending non-conservatively higher over a period of time,then action was to be initiated, including initiating the corrective action process, ifthere was a gap between ODCM requirements and sample locations. Exelonsubsequently compared the data in June 2011 and placed this issue in the CAP (AR1226202).Enclosure 23. The inspectors identified that Exelon's QA program for meteorological dataevaluation failed to detect that the existing ground-level meteorological )UQ value,for the Units 2 and 3 vent stacks, used in the ODCM for purposes of dose projection,was non-conservative relative to the latest calculated long term meteorologicalaverage values resulting in potential incorrect dose calculations. Exelonsubsequently evaluated this new data in December 2011 and concluded there wasno significant change in critical sector dose projections and that public doseprojections continued to be well within 10 CFR Part 50, Appendix l, ALAM designvalues and 10 CFR 20.1301(e). Exelon placed this issue into its CAP (AR 1299543).. The inspectors identified that Exelon did not conduct an evaluation of its first,second, and third quarter 2011 inter-laboratory cross-check samples to determineif sample analyses met applicable QA requirements, as required by ProcedureCY-AA-130-201, Revision 1, "Radiochemistry Quality Control," Section 4.3. Thecross-check samples that were not evaluated included: tritium; gross alpha;Sr-89/90; and filter gas and solid samples. The inter and intra laboratory sampleswere subsequently evaluated in December 2011 using the criteria within ProcedureCY-AA-130-201, Attachment F. Exelon placed this issue into its CAP (AR1299476).. The inspectors identified that Exelon's QA program did not ensure that actual QAsample analysis results, obtained from a vendor laboratory for analysis, weresubsequently critically evaluated against applicable criteria specified in procedures.Exelon did not conduct its onsite biennial evaluation for liquid tritium analysis duringsecond quarter 2011 sampling activity, in that a traceable standard was not analyzedonsite in accordance with the QA program requirements specified in CY-AA-130-201Revision 1. Exelon subsequently placed this issue into its CAP (AR 1302720), andsuccessfully performed the analysis in December 2011.o The inspectors identified that Exelon's QA cross-check procedure, RT-C-095-861-2,"Radiochemistry Intra-laboratory Cross-Check Analysis Program," did not containsufficient guidance to ensure appropriate analytical data was used for sample inter-comparison resolution. Exelon subsequently identified similar concerns in othercross-check procedures. ln addition, incorrect sample inter-comparison analysisresultswere identified (e.9., November 14,2011 tritium sample analysis). Exelonplaced this issue into its CAP (AR 1303308) to correct the procedural deficienciesand re-perform the cross-check using appropriate analytical methods.Given the identified issues, Exelon conducted extensive re-analysis of projected offsitedoses taking into consideration new Land Use Census data as well as the identifiedchanges in meteorological parameters. Exelon concluded there was no significantimpact on public doses and public dose projections remained well within 10 CFR Part 50Appendix I ALARA design specifications. Exelon also reviewed environmental sampledata and did not identify any anomalous results. Exelon also evaluated those samplesresults (as well as inter-comparison results) that had not been critically evaluated (orincorrectly evaluated) and concluded, based on data review, that the sample results metcomparison criteria once evaluated properly. Exelon was continuing its data review.Further, Exelon conducted a liquid tritium analysis and concluded that the analysisresults were within acceptance criteria. The inspectors discussed and selectivelyreviewed Exelon's analyses and did not identify any significant dose consequence.Enclosure 24Analvsis. Exelon did not establish, implement, and maintain an adequate QA program inthe area of etfluent and environmental monitoring as required by Peach Bottom Units 2and 3 TSs, Section 5.4.1.c, for elements of its effluent and environmental monitoringprogram. Specifically, Exelon's QA program for effluent and environmental monitoringwaJnot sufficiently robust to ensure: 1) that both adequate and timely evaluation andassessment of chinges described in the 2010 Public Land Use Census were conductedfor purposes of dose validation and sampling program modification; 2) that changes inmeteorological parameters, used for public dose projections and assessment, werepromptly a-nd adequately evaluated; and 3) that laboratory QA programs, for effluent andenvironmental sample analysis measurement systems were both adequate andimplemented. The failures to establish, implement, and maintain such a QA programwas reasonably within the Exelon's ability to foresee and should have been prevented.The finding is more than minor because it is associated with the Public Radiation Safetycornerstone attribute of programs and processes and adversely affected the associatedcornerstone objective in thai failure to establish, implement, and maintain an adequateeA program inine effluents and environmental monitoring program area adverselyaffeiteO the licensee's ability to ensure adequate protection of public health and safety'Specifically, Exelon's QA program for effluent and environmental monitoring, was notsufficienly robust to ensuie: i; tnat adequate and timely evaluations and assessment ofchanges described in the 2010 Public Land Use Census were conducted for purposes ofdose validation and sampling program modification; 2) that changes in meteorologicalparameters, used for public dose projections and assessment, were evaluated in anadequate and timely manner; and 3) that laboratory QA programs for effluent andenviionmental sample analysis measurement systems were adequate and properlyimplemented.This finding was assessed using IMC 0609, Appendix D, and determined to be of verylow safetyiignificance (Green) because: the issue was contrary to the licensee's TSs;there wai no indication of a spill or release of radioactive material on the licensee's siteor to the offsite environs that would impact public dose assessment; and there was nosubstantial failure to implement the radioactive effluent release program. The licenseewas able to re-assess the dose to members of the public from routine releases anddetermined that projected doses did not nor were likely to exceed applicable limitsincluding ALARA design specifications of 10 CFR Part 50, Appendix l, or ..10 CFR20.1301(e). There was no effluent monitor calibration issue and the licenseehad data by which io assess dose to a member of the public. Exelon plans to provideupdated efiluent release and dose reports, as necessary, to reflect revised analyses.The cause of this finding is related to the crosscutting area of Human Performance,Work Practices, Aspect H.+(O) because the licensee did not ensure personnelfollowedprocedure compliance requirements activities for the effluent and environmentalmonitoring programs.Enforcement. The violation related to this finding is currently under review by the NRC.When that review is completed, the decision relative to any violation will be transmittedto Exelon via separate correspondence. In accordance with NRC IMC 0612, since thesignificance determination of ihe underlying finding has been completed and does notinlerfere with the NRC's current review of the violation, the finding can be issued at thistime. The finding and associated violation, although dispositioned separately, only countaS one input into the plant assessment process. However, the number andcharacterization of violations is subject to change pending the NRC's final review.Enclosure 25Exelon entered this matter into its CAP (ARs: 1226969,12262Q2,1299543,1299476,13O272O,and 1303308), (FtN 0500027712011005-02;0500027812011005'02; Failure toEstablish, lmplement,'and Maintain Adequate QA for Effluent and EnvironmentalMonitoring)2RS07 Radioloqical Environmental Monitorinq Proqram (71124.07 - 1 sample)a.

The inspectors selectivelyreviewed CAP records and projected monthly and quarterly dose assessment resultsdue to radioactive liquid and gaseous effluent releases; for the past four completequarters. The review was against the applicable criteria specified in NEI 99-02,"Regulatory Assessment Pl Guideline," Revision 6. The purpose of this review was toverify that occurrences that met NEI criteria were recognized and identified as Pls.As part of this review, the inspectors also reviewed Exelon's evaluations and public doseassessments, as necessary, associated with identification of localized onsite groundwater contamination within the restricted area.FindinosNo findings were identified.ldentification and Resolution of Problems (71152 - 4 samples)Routine Review of Pl&R Activitieslnsoection ScopeAs required by Inspection Procedure71152, "Problem ldentification and Resolution,"the inspectors routinely reviewed issues during baseline inspection activities and plantstatus reviews to verify that PBAPS entered issues into the CAP at an appropriatethreshold, gave adequate attention to timely corrective actions, and identified andaddressed adverse trends. In order to assist with the identification of repetitiveequipment failures and specific human performance issues for follow-up, the inspectors.4b.40.p.2.1a.Enclosure b.29performed a daily screening of items entered into the CAP and periodically attended CRscreening meetings.Findinqs and ObservationsNo findings were identified.(71152 - 1 annual.2b.sample)Inspection ScopeThe inspectors reviewed the CRs and the corresponding corrective actions from the lastRFO on Units 2 and 3. The inspectors interviewed key site personnel regarding theincidents and changes to the refueling process. The inspectors evaluated effectivenessof the corrective actions, EOC, and station personnel knowledge of the processchanges. The inspectors reviewed Peach Bottom procedures related to FH and therecenl training provided to the FH personnel. The inspectors assessed Exelon'sproblem ident-ification threshold, cause analyses, EOC reviews, compensatory actions,and the prioritization and timeliness of corrective actions to determine whether Exelonperson nel were appropriately identifyi ng, characterizi ng, and correcti ng problemsassociated with this issue, ahd whether the planned or completed corrective actionswere effective. The inspectors compared the actions taken to the requirements ofExelon's CAp and 10 iFR Part 50, Appendix B, "QA Criteria for Nuclear Power Pantsand Fuel Reprocessing Plant." In addition, the inspectors performed in plant walkdownsand interviewed site p6rsonnel to assess the effectiveness of the implemented correctiveactions.The inspectors reviewed Peach Bottom's process to identify, prioritize-, and resolverefuel floor distractions in an attempt to minimize operator burdens. The inspectorsobserved Exelon personnel conducting fuel movement in the reactor vessel during theSeptember 2011 Unit 3 RFO.Findinos and ObservationsNo findings were identified.The inspectors determined that the Exelon corrective actions were comprehensive andimplemented in a timely fashion. Specifically, the just-intime training of the FH crewswas performed at the sjte prior to the Unit 3 outage. The inspectors observed. goodcommunications between the FH crew members during fuel movement' The inspectorsobserved a constant management presence during FH activities. The inspectorsobserved that plant personnel involved with the FH activities were knowledgeableregarding the previous FH events and associated corrective actions. The inspectorsobserved a strong commitment toward zero FH events.The inspectors observed that the revised Potential Obstruction Compensatory Plan'compleied the day before the FH and core verification, would have provided morebenefit to refueling personnel if it had been updated at the start of the Unit 3 RFO. Therevision to the plan'was a corrective action determined from the FH events during the2010 Unit 2 RFO.Enclosure 30.3Review of the Units 2 and 3 Spent Fuel Pool (SFP) Boraflex Deqradation CorrectiveActions (71152 - 1 annual sample)lnspection ScopeThe inspectors assessed Peach Bottom's historical SFP shutdown margin. Theinspectors compared Exelon's SFP Boraflex CAP documentation and 10 CFR Part 50,Appendix B, 'QA Criteria for Nuclear Power Plants." The SFP criticality calculationslisted in lR 1225840-13 were evaluated to determine the significance of the Boraflexdegradation. The Exelon SFP Boraflex technical evaluation was reviewed to determineif the SFP TS sub-criticality margin remained less than
b.31Findinos and ObservationsNo findings were identified.Based on the overall review of the selected sample, the inspectors concluded thatpBApS was appropriately identifying and entering issues into the CAP, adequatelyevaluating the identified issues, and properly identifying a.dverse trends before theybecame riore safety significant problems. However, the inspectors did note the threeadverse trends discussed below'Human performance and configuration control continued to be focus areas for PBAPSduring the second half of 2011. PBAPS identified four configuration control events fromJune-1 through December 1, 2A11, (lRs 1234874 (two events), 1245157, a1! 1271883);seven total in 2011, and five configuration control events were identified in 2010' Acommon cause analysis (ccA) was performed in June of 201 1 (lR 1203953.), and aConfiguration Control Recovery Team was implemented to focus on correcting theadverle trend. Since July 1, two additional configuration control events were noted.None of the configuration control events in 2011 resulted in significant consequences.lndustrial safety issues continue to challenge PBAPS. There were three OccupationalSafety and Heilt6 Administration recordable injuries in September of 2011 (lRs12616gg,1264502, and1265372). Additionally, there were 45 first aid events during'theSeptember and October 2011Unit 3 RFO (P3R18). PBAPS identified this negativetrend, and has performed a CCA to address the adverse trend in industrial safetyperformance during P3R18 (\R1277414). The inspecto_rs noted that PBAPS hasferformed additionil causal investigations in the area of industrial safety performance:a CCA was completed in April of ZOtl to address an inadequate trend in industrial safetyperformance between January 1 and April 25 of 20]l (lR 1203002): and an ApparentCause Evaluation was completeO in November of 2011 in response to Nuclear OversighttruOSl identifying pBAPS's failure to complete actions to address unsatisfactoryperformance from 2010 in the area of industrial safety'The inspectors identified an adverse trend in the area of equipment reliability. Duringthe review period from June 't to December 1, 2011, PBAPS submitted five licenseeevent reports (LERs) related to degraded or failed equipment, and also noted a sixthequipment reliabilitY issue:o Failed Relay Results in Unplanned EDG Actuation during Surveillance Testing(LER 0500 0277 l2O1 1 -003-00)o EDG Oil Leak (LER 0500027712011-004-00)o Hardened Grease in a Safety-Related MOV (LER 05000278/2011-001, this findingwas documented in Section 1R12 of this report)o Leaking Relief Valve in the RHR System (LER 0500027812011-002-00).

Repeiitive Leaks on the Unit 3'B'RWCU System (lR 1281888)The inspectors verified that all of the equipment issues identified above have beenentered into the PBAPS's CAP.Enclosure 32.5Actions(71152- 1 annual samPle)Inspection ScopeThe i"spectors 'eviewed licensee actions to resolve vital bus degraded voltageprotectibn issues. The inspectors selected lR 01 119440 as a Pl&R sample for a detailediollow-up review because it tracked the analysis and disposition of the issue' Therewere numerous lRs associated with the vital bus degraded voltage protection issue. Asdocumented in NRC Inspection Report 0500027712008007 and 0500027812008007, anunresolved item (URl) was opened to determine whether the approved PBAPS licensingbasis included the use of automatic load tap changers (LTCs) to protect the vital"r"tg"n.y buses from unacceptable low voltage co1d!!i91s during a design basisLOCA. As documented in inspection report 0500027712010004 and 0500027812010004,the NRC, Region l, requested that a formal review (task interface agreement (TlA) 2009-007) be cond-ucted Oy tfre NRC, Nuclear Reactor Regulation to resolve the issue' Thelnaf ttn response determined that PBAPS license basis for degraded voltage relayiettings did not include credit for the LTCs on the startup transformers to protect theclass"l-E safety-related equipment during a design basis LocA. The inspection reportalso closed the URI and enforcement action was documented. The licenseesubsequently issued LER 2010004-00 which was reviewed by the Nfp and closed asdocumentedin inspection report 0500027712010005 and 0500027812010005 with noadditional enforcement action.The inspectors assessed Exelon's problem identification threshold, EOC reviews,operabiiity evaluations, technical evaluations, modification packages, a1d interimcompensatory measures. The inspectors also assessed Exelon's prioritization andtimeiiness of corrective actions to determine whether Exelon was appropriatelyidentifying, characterizing, and correcting problems associated with the identified issueand whether the compleieO or planned c-orrective actions were appropriate to preventrecurrence. Additionally, the inspectors performed walkdowns of accessible portions ofaffected motor control ienters (lrrtCCs) and components to assess if abnormal conditionsexisted. The inspectors also interviewed plant personnel to gain insights regarding theidentified issues and implemented or planned corrective actions'Findinqs and ObservationsNo findings were identified.The inspectors determined that Exelon properly implemented their CAP regarding theinitial discovery of the reviewed issue. The lR package was complete and included'operability evaiuations, technical evaluations, interim compensatory measures, EOCreviews, and contained implemented and planned corrective actions. Additionally, theelements of the lR, technical evaluations, and operability evaluations were detailed andthorough. lmplemented and planned corrective actions appeared appropriate tominimiie the potential of recurrence. The inspectors determined that corrective actionsincluded performing an operability evaluation, which included electrical calculations thatused the most limiiing uoitrg" level allowed by the TS (excluding the LTC), identifyingcomponents that wou"ld not-have adequate voltage to operate under the identified.ondition, implementing interim compensatory measures (revising operationsprocedures and operaior training) to operate equipment that would not have adequatea.b.Enclosure 33voltage to operate in the design basis LOCA, and creating and implementingmodification packages for MOVs and MCCs to allow equipment to operate under theanalyzed condition. The inspectors found the operability evaluation and interimcompensatory measures reasonable. Exelon had completed all modificationsassociated *itn ftlOvr and MCCs that would not have adequate voltage during a designbasis LOCA.Additional corrective actions included performing an evaluation of vital buses at a lowervoltage (3737 volts) than the TS lower limit for the function four LOCA relay setting. Thisanalysis'was perfoimed to identify equipment needing margil impro.vement, butremiined operable for the TS function four relay setting band. The inspectorsdetermined that Exelon had completed modifications on some of the equipmentidentified in the analysis and had scheduled modifications on the remaining equipmentidentified..6 ldentification and Resolution of Problems (71124.01,71124'Q2,71124'03,71124'04,71124.05,71124.06)a. lnspection ScoPeThe inspectors selectively reviewed corrective action documents for occupationalradiation safety program and effluent and environmental monitoring program' Seedocuments reviewed.The review was against criteria contained in 10 CFR ParI20, TSs, ODCM, andapplicable station audit and surveillance procedures'b. FindinqsNo findings were identified.(71153 - 4 samples)(closed) LER 05000277/2011003-00: Delayed Relay operation Results in E-3 EDGActuation during Surveillance TestingOn Septem ber 21, 2011, during the P3R18 RFO, an unplanned, valid actuation of theE-3 EDG occurred during surveillance (functional) testing of the E-33 4 kV emergencybus undervoltage relays.- The E-3 EDG started unexpectedly when time delay relay3-54-1g3-1708 did noi operate properly, resulting in a delayed E-33 bus fast-transferbetween the TS off-site sources. This delay resulted in the operation of an additionalundervoltage relay and thereby caused a valid actuation of the E-3 EDG on low voltage'Because the E-33 bus delayed fast transfer occurred prior to the EDG reaching fullspeed and voltage, the EDG output breaker was not required to close.The cause of the event was due to the failure of the 3-54-183-1708 time delay relay topioperty tunction. The relay was replaced and tested satisfactorily. There was no actualsafety consequences assoiiated with this event. PBAPS entered this item into the CAPfor additional evaluation and investigation. The inspectors determined that there was noperformance deficiency associated with the failed relay. This LER is closed.40A3.1Enclosure 34.2(Ctosed) LER 05000277/2011004-00: Oil Leak Resulting in E-1 EDG lnoperabilityOn September 23,2011, during the P3R18 RFO, an oil leak was discovered on the E-1EDG when the engine was being shutdown during 4kV emergency bus lesting. The leakwas determined to be from a crack on the lube oil drain line for the combustion air intakeblower (supercharger). Analysis determined that the leak previously existed and theEDG would not have been able to perform its safety function to successfully run for a24-hour mission time.pBApS determined that the cause of the event was ineffective maintenance practices,and the drain line should have previously been replaced during maintenance activities.The leaking drain line was replaced on September 23,2011, and the E-1 EDG wastested suciessfully with no leaks in the drain line. PBAPS entered this issue into theCAp, performed EOC inspections, and took corrective action to revise the associatedmaintenance procedure. The enforcement aspects of this LER are discussed in Section4OA7. This LER is closed.(Ctosed) LER 05000278/2011001-00: Containment lsolation Valve Inability to Close fora Design Basis Event due to Degraded LubricantOn Septem ber 22, 2011 , during the P3R18 RFO, it was identified that the ability of theUnit 3 RWCU outboard isolation valve (MO-3-12-018) to close was degraded due to amotor-operator greasing deficiency. This deficiency was identified during performanceof routine MOV maintenance and diagnostic testing. lt was determined that thiscondition was prohibited by TSs since this primary containment isolation valve wasdetermined to be inoperable for containment isolation purposes during the previousoperating cycle for a time period longer than allowed by TS. The cause of the greasingdeficienjy was due to inadequate lubrication. The valve was repaired on September 23,2011. There was no actual safety consequences associated with this event. Theenforcement aspects of this LER are discussed in Section 1Rl2' This LER is closed.(Ctosed) LER 05000278/201 1002-00: RHR Leaking Relief Valve Results in ConditionProhibited by TSOn September 19, 2011, during the P3R18 RFO, Engineering personneldetermined thata leak on the inlet connection to the'D' RHR suction piping thermal relief valve was dueto cracking of the relief valve body and not due to a mechanicaljoint leak as originallyidentified -uring cycle 18 operations on April 27 , 2010. On April27 , 2010, PBAPSidentified the leik to be one drop per two minutes, and incorrectly determined that theleak was from a threaded connection. Subsequent non-destructive evaluation followingthe September 19, 201 1 determination confirmed the leak to be through the relief valvebody. Based on analysis, PBAPS determined the relief valve could have becomedetjched from the piping during the worst case design basis seismic event' Thiscondition would resuit in tfre 'D; RHR pump being inoperable, thereby affecting theRHR low pressure coolant injection function.pBApS determined the cause of the delay in identifying the inoperable condition wasdue to inadequate technical rigor when evaluating the operability of the relief _valve onApril 27, 2010. The leaking relief valve was replaced on October 2,2011. EOC reviewswere performed for similar components in Unit 2 and Unit 3. Operations has instituted.3.4Enclosure a.35additionaltraining and procedure revisions to drive improved performance regardingoperability evaluitions. There were no actual safety consequences as result of thisevent. This event was considered as a condition prohibited by TSs and loss of safetyfunction. The enforcement aspects of this LER are discussed in Section
lnspection ScoPeThe inspectors selectively reviewed routine operational surveillance data, includingradiological surveillance,ior the Independent Spent Fuel Storage Installation (lSFSl)facility. The inspectors toured the facility and made independent radiationre"rur"rents of the facility. The data was evaluated against 10 CFR Part 20 andapplicable Exelon Procedures.FindinqsNo findings were identified..2a.Enclosure 364046 Meetinqs. lncludinq ExitQuarterlv Resident Exit Meetinq SummarvOn January 20,2012, the resident inspectors presented the inspection results toMr. Thomas Dougherty and other PBAPS staff, who acknowledged the findings.Mr. P. Krohn, Cniet, U-SrunC, Region 1, Division of Reactor Projects, Branch 4,attended this quarterly inspection exit meeting. The inspectors verified. that noproprietary informatioh was retained by the inspectors nor documented in this report'4C,A7 Licensee-ldentified ViolationsThe following violations of very low safety significance (Green) were identified by thelicensee "nd-rr" violations of runC requirem-ents which meet the criteria of the NRCEnforcement Policy for being dispositioned as NCVs'. TS b.4.1 states, in part, that written procedures shall be implemented a1d maintainedas recommended ln nC 1.33, Appendix A, November 1972. RG 1'33, Appendix A'Section l, "procedures for Performing Maintenance," subsection 1, states thefollowing: "Maintenance which can affect the performance of safety-relatedequipm6nt should be properly preplanned and performed in accordance with writtenprocedures, documenied insiructions, or drawings appropriate to the circumstances'bkill, nottally possessed by qualified maintenance personnel may not requiredetailed step--by-step delineition in a procedure." Contrary to the aboye,. PBAPSdid not properly preplan and perform maintenance which affected the E-1 EDG'Specifically, pAApd determined that a damaged lubricating oil drain line should havebeen identified and replaced during planned maintenance activities prior to theoccurrence of leakage. As a consequence of not identifying and replacing thedamaged drain line,-pBAPS determined that the E-1 EDG was unable to perform its24-hour mission time, and therefore was inoperable, during the period of timebetween April27 , 2011, and September 23, 2011'The finding was determined to be of very low safety significance, for both PeachBottom Units 2 and 3, in accordance wit-h lMc 0609, Appendix A, "Delgrlnining theSignificance of Reactor Inspection Findings for At-Pow-er Situations" (lMC 06094)uslng SDp phase s 1,2 and 3. Phase 1 screened the finding to Phase 2 becauseit reiresented a loss of the E-1 EDG safety function, between April27 andSepiember 23,2011 (149 days), longer thln the TS limiting condition for operation(Lco) of 14 dayi. A ilegion i senioi Reactor Analyst (SRA) conducted a Phase 3analysis because the Phlse 2 analysis, conducted by.the inspectors using- the PeachBottom pre-solved Risk-lnformed lnspection Notebook, indicated that the findingcould be more than very low significance'The SRA used the peach Bottom Standardized Plant Analysis Risk (SPAR) model,Revision 8.19 and 8.17, for units 2 and 3 respectively and SAPHIRE 8 to conductthe phase 3 analysis, with the conservative assumption that the E-1 EDG would nothave operated at all for its 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> mission time over the 149 day exposure period'This analysis was conservative given the EDG could have operated for over twohours assuming that the drain line broke and the potential that operators could havetemporarily limiied the leakage from the supercharge lube oil drain line. ThisEnclosure 37analysis indicated an increase in core damage frequency (ACDf) forinternalinitiaiing events in the range of one core damage accident in 2,500,000 years ofreactor operation, in the low E-7 range per year for each unit. The dominate coredamage sequences included losses of offsite power with the failure of all EDGsresulting in a station blackout (SBO), followed by the failure of operators to reducedirect current loading to allow extended operation of the RCIC system alq -depressurize the realtor, and with inability to recover offsite power, the SBO sourceof power from the Conowingo Dam or an EDG in two hours. In accordance with IMCOObgR, for a finding with an internal events ACDF above 1E-7, the SRA assessedthe impact of the tinOing on: 1) External events such as fire, seismic and flooding,determining, using the external events portion of the Peach Bottom Unit 2 and 3SpAR modlls, tfrit tne total ACDF (internal plus external) would not be above the1 E-6 threshold; and 2) the increase in large early release frequency (ALERF)'determining that given the operators ability, following core damage, to recover offsitepower and depressurize and inject water to the reactor from low pressure sourcesand to flood the containment that the ALERF was in the low E-8 per year range'Because this finding is of very low safety significance and has been entered intoExelon's CAp under lR 1266b37, this violation is being treated as a Green, licensee-identified NCV consistent with the NRC Enforcement Policy.. TS LCO 3.5.1, Condition A, requires that one inoperable low pressure ECCSinjection subsystem should be iestored to an OPERABLE status within seven daysduring operatibnal modes 1 and 2, or requires action to place the unit in operationalmode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Contrary to the above, the 'D' LPCI pump was inoperableduring a period of time between April27,2O1O, and October2,2011. Specifically'pBApS determined that the leaking relief valve body, as identified on April 27,2010,could have become detached from the 'D' RHR suction piping during the worst casedesign basis seismic event. This condition would result in the 'D' RHR pump beinginop6rable, thereby affecting the RHR LPCI function. Because the 'B' RHR pumpwas unaffected by this even-t, there was no total loss of the 'B' LPCI train safetyfunction. The inspectors determined that this event screens to Green using theTable 4b seismic screening criteria in Attachment 4 of IMC 0609, "SDP." Becausethis finding is of very low sifety significance and has been entered into Exelon's CAPunder lR i264g09, ihis violation iJbeing treated as a Green, licensee-identified NCVconsistent with the NRC Enforcement Policy'ATTACHMENT:
