The team'sfocusin addressingthisinspection elementwasontheprocessHMDuses1)to control procedure distributionand2)to translate vendorsupplieddesign information into controlled HMD procedures and drawingsforfabricationactivities.
Document ControlTheteamreviewedthe documentationcontrolprocesstoverifyitwasbeingproperly implementedatHMD.Thefollowing procedureswerereviewed:
Holtec Quality Procedure#Revision Title 6.0 10 Document Control 6.1 8 Project Document TransmittalandControl HMD personnelshowedtheteamhownewproject documentsorchangestoongoingproject documents are generatedatthe CorporateDivisionand transmittedtothe manufacturingdivision(HMD)viaa Document TransmittalForm(DTF).Thesedocuments,namelyreports, procedures, specifications,drawings,etc...,arereviewedandapprovedbythe designated Project Manager (PM).Afterreview,thePM approves the distributionofthe documents to locationswithintheHMDfacilitywhereneeded.When changes/revision to drawingsaremade,thePMissuesaDTFtoa designated HMD employee to physicallyreplacethepaperdrawings,locatedat documentationareasineachfabricationshop,withthelatestrevision.TheteamreviewedseveralDTFsusedtoreplaceexisting drawingsinthe fabricationshopandverifiedthattheprocesshadbeenproperly implemented.HMDusesa computerizedsystemforallitsprojectstoarchive,distribute,processandtrackrevisionsforall associatedprojects.Thesystemis effectively implementedatthe documentareaswithineach fabricationshopbyhavingpapercopiesof drawingsavailableanda computerterminalavailablethatallowsHMDpersonneltoretrievethemostupdated document information.Theteamspotverifiedthattherevisionnumberofpaperfabricationdrawingsprovidedatthe documentareaintheNorthfabricationshopwerecurrent,andverifiedthat travelersbeingusedonthe fabricationshopfloorwere incorporatedintothe computerized system.ControlofDesign InformationTheteamnotedthatthedesign developmentprocessforHoltecoccursat theircorporateofficesinNewJersey.The translationoftheintendeddesignatthe fabricationlevelandfromthe corporate design drawingswasverifiedbytheteam.Theteamusedsamplesofmaterialsfromtheshopfloorandtracedthembacktotheirassociatedpurchaseordersand applicable designdrawings.Ineachcase,theteamverifiedthatthematerialsamplesconformedtothe requirementsofthe associateddesigndrawlnqs.Page2of10 Theteamalso reviewed various statements made in Section9oftheFinal Safety Analysis Report (FSAR)forthe HI-STORM system (CoC 72-1014)to verify they were properly implemented in appropriate fabricationortest proceduresusedatHMD.The resultsofthis review are discussed below.The team reviewed the following relevant design parameters and verified thattheywere appropriately translatedfromthe FSAR licensing drawingstotheHMD fabrication drawings: Requirement FSAR Location HMO Document/drawingFuelcellpitch CoC#1014 AppendixB3.2.5DWG3752 MPC-32 FUELDWG3927 Sheet3Rev16 BASKET ASSEMBLYRev13MPCLifting Holes Min.DWG 3923 Sheet7Rev25DWG3753MPC SHELLRev28 Depth Overpack Shielding DWG 4116 sheet2Rev19 DWG 3996 HI-STORM 100S Thickness VERSIONBRev33 FSAR Section 9.1.1[Fabrication and Nondestructive Examination (NDE)], paragraph 4, states thattheMPC, HI-STORM Overpack, and HI-TRAC cask weldsshallbe visually examined in accordance with ASME Code,Section V, Article9with acceptance criteria per ASME Code,Section III, Subsection NF, Article NF-5360, excepttheMPCfuel basket cell plate-to-cell plate weldsandfuel basket support-to-canisterweldswhichshallhave acceptance criteria to ASME Code Section III, Subsection NG, Article NG-5360.Itis further stated in paragraph4that FSAR Table 9.1.4 identifies additional nondestructive examination (NDE)requirementstobe performed on specificwelds,andthe applicable codes and acceptance criteriatobeusedin order to meet the inspection requirementsofthe applicable ASME Code,Section III.Acceptance criteriaforNDEshallbein accordancewiththe applicableCodefor whichtheitem was fabricated.
These additional NDE criteriaarealso specifiedonthe design drawingsforthe specific welds.The team requested copiesoftheMPCand HI-TRAC fabrication drawings to determineifthe NDE requirements for specific welds were properly incorporated from FSAR Table 9.1.4tothe fabrication drawings.Drawing 4838, Sheets1-9,revision16 (Standard MPC-Shell and Details for MPC-24,32,&68)and drawing 7464, Sheets 1-3, revision 1 (Sub-assembly, HI-TRAC 125D VersionA)were provided.Theteam reviewed the drawings and determinedthattheNDE requirements for specific welds shown in FSAR Table 9.1.4hadbeen properly incorporated into the fabrication drawings.FSAR Section 9.1.2.1 (Lifting Trunnions)
requires thattheHI-TRAC lifting trunnions be tested at 300%ofthe maximum design (service)liftingloadand thattheloadshallbe appliedfora minimumof10 minutes.The accessiblepartsofthe trunnionsandthe adjacent HI-TRAC cask trunnion attachmentareashallthenbe visually examined to verify no deformation.
The team reviewed procedure HSP-113, revision 8,"Trunnion Load Test Procedure for HI-TRAC100and 125 Systems," and determined that the FSAR requirements fora300%loadtest,10 minute minimumholdperiod,and post test inspections,hadbeen properly incorporated.
FSAR Section 9.1.5.2 (Shielding Effectiveness Tests)requires that effectivenessofthelead platesinthe HI-TRACpoollid(all transfer cask designs)and transfer lid (HI-TRAC125and100only)shallbe verified during fabrication by performing an ultrasonic test(UT)ontheleadplates.TheUTis performed before the installationoftheplates.Theteam reviewed procedure Page3of10 SC-240, revision 0,"Ultrasonic ExaminationofLeadBasedPlate,"anda material dedication reportforleadplatetobeusedina HI-TRACPoollid.Theteam determinedthatUT thickness testingonleadplates prior to installation in HI-TRACpoollidswasbeing performedasstatedintheFSAR.FSAR Section 9.1.5.2 (Shielding Effectiveness Tests)permits,asan alternativetopouredleadinthe HI-TRAC 125D transfercaskbody,theuseof individual lead sheets layered together.FSAR Section 9.1.5.2 specifiesthat,"All sheets regardless of thicknessshallbe measured for thicknessinatleast four corner locations,ata minimumoftwo inchesfromanyedge."The team reviewed procedure HSP-336,revision9,"Lead Installation Procedure for HI-TRAC." While there were detailed instructionsinthe procedure for inspecting and installingthelead sheets, therewasno specificstepfor measuring the thicknessofthe individual lead sheets at their fourcorners.The discrepancy betweentheFSAR statementandthe fabrication procedure was broughttothe attentionoftheHMDQA Managerandtheissuewas documented in Quality Program Violation(QPV)854.Further discussion with Holtec/HMD personnel indicatedthatthe intent of these measurementswasforuseon thicker lead sheetsandthatthe thinner sheetsbeinguseddidnot require this measurement.
FSAR Section 9.1.2.2.1 (HI-TRAC Transfer Cask Water Jacket)provides hydrostatic pressure requirements for testing the HI-TRAC transfer cask water jacket.The section statesthatthe testingshallbein accordance with written and approved procedureswiththe test pressure gauge installedonthe water jackethavingan upperlimitof approximately twice thatofthe test pressure.Theteam reviewed procedure HSP-112, revision 6,"Hydro-test Procedurefor TRAC100and125 TransferCasks,"and determinedthatthe procedure step addressing pressure gaugesstatedthat,"Analogtype gaugesshallbe graduatedoverarangenotlessthan 1.5 timesnormorethan4 times the required test pressure." Therefore, the procedure requirement for pressure gaugesdidnotmatchtheFSAR statement.
This discrepancy was broughttothe attentionoftheHMDQA Manageranditwas includedonQPV854, written for the previous issue discussed above.Thetwo issues documentedintheQPV were discussedwiththe Holtec CorporateQAManager.Theteamwas informedthatthe FSAR Section 9 discrepancieswouldbe addressed through the10CFR 72.48 processandthatafull reviewofFSAR Section9wouldbe undertaken by Holtec to ensure therewereno other statements that werenotbeing implementedinHMD fabrication or testing procedures.Theteam assessed that therewasno safety significancetothe differences betweentheFSAR statementsandtheactual fabrication and testing procedures.Thisfailureto complywith10CFR72.146,"Design control," constituted a violation of minor significancethatisnot subject to enforcementactionin accordancewiththe NRC's Enforcement Policy.02.02: Determine whether corrective actions for identified fabrication deficiencies have been implementedina time frame commensurate with their significance, and whether nonconformance reports documenting the deficiencieshavebeen initiated and resolved.Theteam reviewed Holtec Quality Procedure(HQP)15.2,"Nonconformances," the procedure thatispartofthe problem identification and corrective action program,usedby HMD/Holtec, applicable to nonconformances.Theteam reviewed a representative sampling of nonconformance reports.Resolutionofthe issues documentedinthe various reports was assessedtobe appropriatewiththereports closedina timeframe commensuratetotheir importance.Inthefewcases where human performance or programmatic issues appeared asPage4of10 contributorycausestoanNCR,theteamnotedthattheseissueswere appropriately documentedthroughthe higherlevelQualityProgramViolation correctiveactionprogramprocess.TheteamalsoverifiedthatforNCRsthatwereinopenstatus,theaffected componentsintheshophadbeentaggedasrequiredbyHQP15.2.TheteamnotedthattheQuality Manager(QM)isrequiredtoperformtrackingandtrendingofallNCRs.Theteam discussedwiththeCorporateQA ManagerhowtrendingisperformedandtheresultspresentedtoHoltec management.Theteamwasprovidedcopiesofthelasttwo HMO QuarterlyNCRReports(2ndand3rd Quarter-2010)fromwhichtheteamverified appropriatetrendingofNCRswasoccurring,asrequiredbyHQP15.2,andthatthis information was presentedforHoltec management review.Overall,noconcernswereidentifiedinthe mannerinwhichHMOresolves nonconformances.
02.03: Determine whether individuals performing quality-related activities are trained and certified where required.TheteamreviewedNOEpersonnel certificationrecordstoascertainthattheywerecertifiedin accordance with ASNT-TC-1a-1992editionsandHoltec procedureHQP-9.1,revision11,"WrittenPracticefor QualificationofNOEPersonnel."Theteamreviewed qualification recordsofaPTLevelII InspectorandanRTLevelII Inspector and determinedtheywerebothqualifiedandcertifiedin accordancewithHMOHCP-9-1.
02.05a: Determine whether materials, components, and other equipment received by the fabricator meet DCSS (dry cask storage system)design procurement specifications.
02.05b: Determine whether the procurement specifications conform to the design commitments and requirements contained in the SAR and, as applicable, the CoC or the site-specific license and technical specifications.
ProcurementTheteamreviewed procurementprocedures,reviewedvariousapproved vendorauditsand surveillances,andtracedthe procurementhistoryof components undergoing fabrication toverifythattheywereprocuredfromqualifiedsuppliersandmet specifications.
As discussedin02.01above,theteamobtainedasamplingofmaterialsinuseontheshopfloorforusein evaluatingHMO'smaterial procurementprocess.HMO staff demonstrated traceabilityforeachofthematerialsselectedbacktotheapplicablepurchaseorderandtheassociatedheat/lotnumbers.Theteamalsonotedthat10CFRPart21(Part21)
