NRC Question 1Pleaseprovide asummarylist ofthosecontainmentpenetrations(includingtheirtestscheduleintervals)thathavenotdemonstratedacceptableperformancehistoryinaccordancewiththeprimarycontainmentleakagerateprogram.

Page1of10 SerialNo.08-0176DocketNo.50-281 Attachment 1 MechanicalTypeC Penetrations In accordancewiththe guidanceofNEI94-01,Rev.0, mechanical penetration valves with acceptable performancemaybeplacedona 60-month testing interval after passing two consecutive refueling outagetests.Ifthevalvefailsatest,itisreturnedtotheshortinterval (every outage)untilitagain passes two consecutive refueling outage tests.Attachment 3 includes tables that providethetest historyandthe currentrequiredtest frequencyforthe mechanical penetrations.

The unacceptable leakageratetestresultsforthe mechanical penetrations are identifiedinboldtypeinthetables.

These penetrations were placedonthe shorterintervalandhavebeenorwillbe tested each refueling outageuntiltwo acceptable tests were/are performed.

The 5-year extensiontotheTypeAtestintervalwillhavenoeffectontheType Band C test programsorthetest frequencies.

NRC Question 2 Please provide a summarytableforType B and Type C tests (including the interval schedule dates)thatare plannedtobe performed prior to and during the requested 5-year extension period of the integrated leakratetest(ILRT)interval.

Dominion ResponseAsnotedabove, Attachments2and3 include tables that providethetest historyandthe current test frequencyforUnit2 electrical and mechanical penetrations, respectively.

Currently, the electrical penetrationsareona 60-month test schedule.Withfew exceptions, the mechanical penetrationsarealsoona 60-month test schedule.Bold entriesinthetablearethe penetration/valves with"as-found" leakageresultsthat exceeded the acceptance criterionandrequiredan increased frequency in testing.NRC Question 3 Regulatory Position C.3 of RG 1.163 recommends that visual examinations should be conducted prior to initiating aTypeAtest, and during two other refueling outages before the nextTypeA test based on a 10-year ILRT interval.Pleasedescribe,with a schedule, how you would supplement this 10-year interval-based visual inspections requirementforthe requested 15-year ILRT interval.Page 2of10 SerialNo.08-0176DocketNo.50-281 Attachment 1 Dominion ResponsePerSection9.2.1ofNEI94-01,Rev.0,and RegulatoryPositionC.3ofRG1.163,the normal inspection frequencyrequiresthree examinationsinthe 10-yearinterval.Two examinationsarerequiredduringthe 10-yearintervalwithathird examinationjustpriortotheTypeAtest.

In accordancewithNEI94-01,Rev.0,ageneralvisual examination is performedoftheaccessibleinterior and exterior surfacesofthe containment and components, includingthelinerplate,forstructuralproblemsthatmayaffect either the containment structureleakageintegrityorthe performanceoftheTypeAtest.SurryUnit2has completedgeneralvisual examinationsduringthecurrent 10-yearIntegratedLeakRateTest(ILRT)intervalin:

• October 2003*October 2006Baseduponapprovalofthe 5-yearextensiontotheILRTinterval,two additional examinationswillneedtobecompleted,oneofwhichwillbeduringtheoutageoftheTypeAtest (October2015).Theother examinationwillbe scheduledduringoneofthefollowingoutages:

• October 2009*October 2012Inadditiontothese examinations,generalvisual examinationsofthe containment linerareperformedin accordancewiththeIWESectionoftheASMECode.NRCQuestion4 Please provide information relativetothe findings (if any)and actionstakenwhere existence of or potential for degraded conditions in inaccessible areas of the containment structure and metallic liner were evaluated based on conditions found in accessible areas as required byTitle10 of the Code of Federal Regulations(10CFR), Part 50, Section 50.55a(b)(2)(viii)(E) and 10 CFR 50.55a(b)(2)(ix)(A).

Dominion Response No evaluationsper10CFR 50.55a(b)(2)(viii)(E)or10CFR 50.55a(b)(2)(ix)(A) wererequiredforSurryUnit2fromthe conditionsfoundduring examinations.Page3of10 SerialNo.08-0176 DocketNo.50-281 Attachment 1 NRC Question 5InSection 4.6 of Attachment 1tothelicensee's letter dated December 17,2007,itis statedthatno augmentedCategoryE-C examinations are plannedforthe second 10-year intervalIWEexaminations.Pleaseprovide a summary ofareasthatwere identified for augmentedexaminationinthefirst 10-year interval IWE.Considering the proposedTSchange per the licensee's letter dated December 17,2007,to allow a 5-year extension of Type Atestinterval,please provide specific information to justify discontinuing the augmented examination of suspectarea(s)duringthe second 10-yearIWEinterval.

Although the caulkhadsomecracks,itwasin relatively good condition,waselastic,andwas firmly adheredtothe concrete.The caulk was estimatedtohavebeen installedatleast10to15yearsprior.Small sectionsofthe caulkwereremovedin approximately 12 different locations.

Only minor surfacerustwasnotedbehindthecaulk.Two areasofthelinerthathad visiblerustand exfoliation justabovethecaulkwere inspected.Thecaulkwas removedandtheloose surfacerustwasalsoremoved.The linerwasthenUT inspected.Onearea measured0.399inches,andthe other area measured at 0.417 inches.(Nominal thicknessforthe lineris0.375inches).

In summary,itwas concludedthatthe existing caulk was firmly adheredtothe concreteandwasnot expected to dislodge and becomedebris.In addition, the linerwasingood conditionwithonly minor surfacerustbehindthecaulk.APlantIssueReportwasissuedto document the condition.

In responsetothePlantIssueReport,theUnit2 containment steel liner to basement concrete floor (Elevation

-27'-7")interface joint wasrestored.Thework scope includedremovalofthe caulk and approximately2"x2"of concretearoundtheliner perimeter; cleaning and coatingofthe exposedliner;and restorationofthe concrete floor.NRCQuestion7Relativetotheresults ofthelastthreeType A tests includedinsection 4.2 of Attachment 1tothe licensee's letter dated December 17,2007,thereis a significantreductionin measured as-foundleakagefrom0.414 LA (May 1991)to0.05 LA (October2000).Please provide further informationrelativetothisreduction.Also, provide the actual as-leftleakageresults and their comparisonwiththe allowableleakagerate specifiedinthe plant TSs.DominionResponse Many factorsmayaffecttheresultsofaTypeAtestas indicated below.*The fundamental approach to testing has changedsince1995.Prior tests extensively drainedandventedthe systems that penetrated the containment boundary.However,since10CFR50 Appendix J, OptionB,wentintoeffect,the containment is isolatedandtheintentisto measure leakagefromthe structure,Page6of10 SerialNo.08-0176 DocketNo.50-281 Attachment 1notfromleakagepathsthatarealreadyincludedinthelocalleakratetest(LLRT) program.*AsindicatedbytheresultsofthepastthreeAs-Foundleakagetests,SurryPowerStationiscommittedtomaintaining containment LLRTleakagevaluesverylowbymaintainingequipmentcondition.*IntegratedTypeAleakageratesarenotconducivetotrendingduetothemanyvariationsthatoccurwhenconductingthetestsandanalyzingthedata.*Duringthe2000Unit2integratedleakageTypeAtest,Unit1trippedfromfullpowerduringUnit2pressurization.ThiscausedchangestoSurry'scoolingwatersystem(commontobothunits),whichaffectedthesteadystateconditionsonUnit2.Theindicatedvalueofinducedleakageratesettledataverystablevalueslightlyabovetheupperlimit.Sevenhoursandsixminutesaftertheinducedleakratetestbegan,theleakwassecured.Followingabriefstabilizationperiod,theTypeAtestwasrestarted.Thisextendedtesttimecausedasignificantreductioninmeasuredas-foundleakagefrom0.59Laforthefirsttestto0.061Laforthesecondtest.PerANSI/ANS56.8-1994and NEI94-01,"theAs-FoundTypeAtestleakageratesmustbelessthantheacceptancecriterionof1.0LagiveninthePlantTechnicalSpecifications.Priortoenteringamodewhere containmentintegrityisrequired,theLeftTypeAleakagerateshallnotexceed0.75La."Unit2 As-FoundTypeA History Dates:Nov1986May1991Oct2000TypeATestResult0.638La0.418La0.060LaTotalLeakageSavings0.090La0.034La0.001LaAs-FoundTypeATotal:0.728La0.452La0.061LaUnit2As-LeftTypeA History Dates:Nov1986May1991Oct2000MeasuredLeakRatewithUCL(UpperConfidenceLimit)Margin0.635La0.414La0.050LaTypeCPenalty0.003La0.004La0.010LaAs-LeftTypeATotal:0.638La0.418La0.060LaPage7of10 SerialNo.08-0176DocketNo.50-281 Attachment 1 NRC Question 8 Ifbellowsareusedon penetrations through containment pressure-retaining boundariesatSurry 2,pleaseprovideinformationontheirlocation,inspection,testingandoperatingexperiencewithregardtodetection ofleakagethroughthe penetration bellows.Dominion ResponseThesinglefuel transfertubefortheSurryUnit2 containment structureistheonlypenetrationthatutilizesabellows arrangementtoestablishsealsbetweenthe containment liner, transfercavity,spentfuelpool,andthepenetrationitself.Pressure test channelsareinstalledontheweldinterfacebetweenthe penetrationpipingandthe containmentlinerandwereusedtoverifyweldqualityduringinitial construction.
