amendment wouldnot(1)involveasignificant increaseinthe.probability orconsequences ofanaccidentpreviously evaluated; or(2)createthepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated; or(3)involveasignificant reduction inamarginofsafety.Eachstandardisdiscussed belowfortheproposedamendments.
Discussion (1)Operation ofthefacilityinaccordance withtheproposedamendments wouldnotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated.
Theproposedamendments donotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated duetothefollowing reasons:a)Theseproposedchangesareallconsistent withNRCrequirements andguidanceforimplementation of10CFR50,AppendixZOptionB,exceptfortheuseofBechtelTopicalReport.BN-TOP-1fortypeAtesting.BN-TOP-1hasbeenpreviously approvedforuseinaccordance with10CFR50Appendix'.
b)BasedonindustryandNRCevaluations performed insupportofdeveloping OptionB,thesechangespotentially resultinaminorincreaseintheconsequences ofanaccidentpreviously evaluated duetotheincreased testingintervals.
However,theproposedchangesdonotresultinanincreaseinthecoredamagefrequency sincethecontainment systemisusedformitigation purposesonly.
St..LucieUnit2DocketNo.50-389L-96-081, Attachment 2Page4of5c)Thesechangesareexpectedtoresultinincreased attention oncomponents withpoorleakagetesthistoryaspartofthe'performance-based natureofOptionB,suchthatthemarginally increased consequences fromtheexpandedtestingintervals maybefurtherreducedornegated.Therefore, thesechangesdonotinvolveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated.
Operation ofthefacilityinaccordance withtheproposedamendments wouldnotcreatethepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated.
Theuseofthemodifiedspecifications cannotcreatethepossibility ofanewordifferent kindofaccidentfromanypreviously evaluated sincetheproposedamendments willnotchangethephysicalplantorthemodesofplantoperation definedinthefacilityoperating license.Nonewfailuremodeisintroduced duetotheimplementation ofaperformance-based programforcontainment leakageratetesting,sincetheproposedchangesdonotinvolvetheadditionormodification ofequipment, nordotheyalterthedesignoroperation ofaffectedplantsystems,structures, orcomponents.
Operation ofthefacilityinaccordance withtheproposedamendments wouldnotinvolveasignificant reduction inamarginofsafety.Theoperating limitsandfunctional capabilities oftheaffectedsystems,structures, andcomponents arebasically unchanged bytheproposedamendments.
Theincreaseinintervals betweenleak-test surveillances willnotsignificantly reducethemarginofsafetyasshownbyfindingsinNUREG1493,"Performance-Based Containment Leak-TestProgram",
whichwasbasedonimplementation oftheperformance-based testingofOptionB.Therefore thesechangesdonotinvolveasignificant reduction inthemarginofsafety.
St.,LucieUnit2DocketNo.50-389L-96-081, Attachment 2Page5of5SummaryBasedontheabove,FPLhasdetermined thattheproposedamendment requestdoesnot(1)involveasignificant increaseintheprobability orconsequences ofanaccidentpreviously evaluated, (2)createthepossibility ofanewordifferent kindofaccidentfromanyaccidentpreviously evaluated, (3)involveasignificant reduction inamarginofsafety;andtherefore theproposedchangesdonotinvolveasignificant hazardsconsideration asdefinedin10CFR50.92.
