Thesecondinspection intervalisdefinedasfollows:August8,1993August7,2003ThisdocumentoutlinestheISTProgramforSt.LuciePlant,Unit2,basedontherequirements oftheASMEBoilerandPressureVesselCode(theCode),SectionXI,1986Edition.References inthisdocumentto"IWP"or"IWV"correspond toSubsections IWPandIWV,respectively, oftheASMESectionXI,1986Edition,unlessotherwise noted.TheISTprogramhasbeenupdatedtoreplacetherequirements ofASME/ANSI OM-1981,Part1withASME/ANSI OM-1987,Part1,"Requirements forInservice Performance TestingofNuclearPowerPlantPressureReliefDevices".

NRCSafetyEvaluations datedAugust23,1993,andMay2,1994determined certainreliefrequestswerenotrequiredpursuantto10CFR50.55a(f)

1.Measurement ofbearingtemperatures asrequiredby'EIWP-3300and'KIWP-4310 arenotrequiredbyASME/ANSI OMa-1988, Part6,forinservice testingofpumps.Therefore, themeasurement ofbearingtemperatures isnotarequirement oftheISTProgram.2.Thevalveexercising requirements ofASME/ANSI OMa-1988, Part10,94.2.1.2and4.3.2.2willbefollowedasalternatives to'3IWV-3412(a) andIWV-3522notincluding IWV-3522(a) and(b).

Theinservice testingrequirements identified inthisPlanwerepreparedtoverifytheoperational readiness ofISIClass1,2,and3pumpsandvalveswhichhaveaspecificfunctioninmitigating theconsequences ofanaccidentorinbringingthereactortoasafeshutdown.

Inthisregard,thegeneralrequirements ofParagraphs IWP-1100andIWV-1100formthefollowing basicscopedocumentasitappliestoISIClass1,2,and3.Specifically components tobeincludedare:Centrifugal andpositivedisplacement pumpsthatarerequiredtoperformaspecificfunctioninshuttingdownthereactororinmitigating theconsequences ofan=accidentandthatareprovidedwithanemergency powersource,andValves(andtheiractuating andpositionindicating systems)whicharerequiredtoperformaspecificfunctioninshuttingdownthereactortothecoldshutdowncondition orinmitigating theconsequences ofanaccident.

Typically, allpumps,power-operated valves,checkvalves,andsafetyvalvesremainedinthepopulation designated forfurtherevaluation.

2.Eachsystemwasbrokendownbycomponent and,basedongeneralsystemoperational requirements, anarrative description ofeachcomponent's safetyfunction(s) duringtheproposedscenarios wasdrafted.3.Sequentially, plantdocuments thatrefertoordiscusssafety-related component orsystemfunctions werereviewedindetailandinformation fromthesedocuments wascomparedtothedraftsdeveloped intheabovestep2.Whereappropriate, corrections andreferences wereappliedtotheindividual narratives.
