Attachment 3SafetAnalsisIntroduction ThischangeisproposedtorevisetheSt.LucieUnits1and2Technical Specifications toremoveTable4.4-5,ReactorVesselMaterialSurveillance ProgramWithdrawal

Schedule, andanyreferences tothetablefromtheTechnical Specifications.

Theappropriate reactorvesselmaterialwithdrawal schedules havealreadybeenincorporated inTable5.4-3oftheUnit1FUSARandTable5.3-9oftheUnit2FUSAR.Discussion Inaccordance withGenericLetter91-01,theproposedchangetotheSt.LucieUnits1and2Technical Specifications revisestheReactorCoolantSystemSection3/4.4.9,Pressure/Temperature Limits,byremovingTable4.4-5andanyreferences tothetablefromtheTechnical Specifications.

AppendixHSectionII.B.'3of10CFRPart50,states,that:."Aproposedwithdrawal schedulemustbesubmitted withatechnical justification asspecified in10CFR50.4.Theproposedschedulemustbeapprovedpriortoimplementation."

HavingthisscheduleintheTechnical Specifications duplicates thecontrolonchangestothisschedulethathasbeenpreviously established in10CFR50AppendixH.Thelimitingconditions foroperation (LCO)fortheReactorCoolantSystemincludeoperating limitsonpressureandtemperature thataredefinedinFigures3.4-2a,3.4-2band3.4-3oftheSt.LucieUnit1Technical Specifications andFigures3.4-2,3.4-3,3.4-4oftheSt.LucieUnit2Technical Specifications.

Theyprovideanacceptable regionforoperation duringheatup,cooldown, criticality, andinservice leakandhydrostatic testing.Thesurveillance requirement associated withthisLCOaddresses thefrequency ofverifying that,operation iswithinthespecified limitsduringtheseoperating conditions.

Alsoincludedisanadditional surveillance requirement thatstates(Thereactorvesselmaterialirradiation surveillance specimens shallberemovedandexamined, todetermine changesinmaterialproperties, attheintervals requiredby10CFR50AppendixHinaccordance withthescheduleinTable4.4-5.Theresultsoftheseexaminations shallbeusedtoupdateFigures3.4-2a,3.4-2band3.4-3-for theSt.LucieUnit1Technical Specifications andFigures3.4-2,3.4-3,and3.4-4fortheSt.LucieUnit2Technical Specifications."

TheproposedchangewouldremoveTable4.4-5,andanyreferences tothetablefromtheTechnical Specifications.

Becausethesurveillance

'l' requirement specifies thattheresultsoftheseexaminations shallbeusedtoupdateFigures3.4-2a,3.4-2band3.4-3forSt.LucieUnit1and3.4-2,3.4-3and3.4-4forSt.LucieUnit2forthepressureandtemperature limitsthisrequirement willberetained.

St.LucieUnits1and2Technical Specification BasesSection3/4.4.9,Pressure/Temperature Limits,givesadetaileddescription ofthebasesforthisLCOandtherelatedsurveillance requirements.

TheStandardTechnical Specification (STS)basesreferences Table4.4-5whichprovidesthescheduleforsurveillance specimenwithdrawal.

ThisBasesSectionprovidesconsiderable background information ontheuseof.thedatagatheredfrommaterialspecimens.

Thisbackground information clearlydefinestheobjective ofthisdataasitrelatesto10CFR50AppendixHandtheAmericanSocietyofMechanical Engineers (ASME)Code.Deletionofthereference toTable4.4-5doesnotaffectthecontentofthissection.Conclusion Thereactorvesselmaterialwithdrawal schedules havealreadybeenincorporated intotheUnit1and2FUSAR.RemovingthemfromtheUnit1and2Technical Specifications willnotresultinanylossofclarityorcontrolovertheregulatory requirements of10CFR50AppendixH.

J Attachment 4Determination ofNoSinificantHazardsConsideration Thestandards usedtoarriveatadetermination thatarequestforamendment involvesnosignificant hazardsconsideration areincludedintheCommissions regulation, 10CFR50.92,whichstatethatnosignificant hazardsconsiderations areinvolvediftheoperation ofthefacilityinaccordance withtheproposedamendment wouldnot(1)involveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated; or(2)createthepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated; or(3)involveasignificant reduction inamarginofsafety.Eachstandardisdiscussed asfollows:(1)Operation ofthefacilityinaccordance withtheproposedamendment wouldnotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated.

Theproposedamendment changedoesnotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated becausetheregulatory requirement of10CFR50AppendixHwillremainineffectintheTechnical Specifications.

RemovingTable4.4-5,andanyreferences toit,willnotresultinanylossofregulatory controlbecausechangestothisschedulearecontrolled bytherequirements of10CFR50AppendixH.(2)Useofthemodifiedspecification wouldnotcreatethepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated.

Theuseofthismodifiedspecification cannotcreatethepossibility ofanewordifferent kindofaccidentfromanypreviously evaluated becauseaspreviously statedinAppendixHSectionII.B.3of10CFR50,thelicenseemusthaveawithdrawal scheduleapprovedbytheNRCpriortoimplementation.

ByremovingTable4.4-5,andanyreferences tothattable,FPLwillonlyeliminate duplication ofarequirement thatitalreadyadherestoin10CFR50AppendixH.(3)Useofthemodifiedspecification wouldnotinvolvesignificant reduction inamarginofsafety.ByremovingTable4.4-5themarginofsafetywouldnotbecompromised becausethesurveillance requirement stillrequiressurveillance specimens toberemovedandexamined, todetermine changesinmaterialproperties, atintervals requiredby10CFR50AppendixH.Inadditiontheresultsof

theseexaminations shallbeusedtoupdatethefiguresforthepressureandtemperature operating limitsrequiredbytheTechnical Specifications.

Basedontheabove,wehavedetermined thattheproposedamendment doesnot(1)involveasignificant

increase, intheprobability orconsequences ofanaccidentpreviously evaluated, (2)createtheprobability ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated, or(3)involveasignificant reduction inamarginofsafety;andtherefore doesnotinvolveasignificant hazardsconsideration.
