Specific schedulingcriteriaare included in IWE-2412forplants,whichareemploying InspectionProgramB.This paragraph references Table IWE-2412-1,whichincludesminimumand maximum percentages of examinationsrequiredtobe completedbyeachinspectionperiod.Table3.3.8-2 summarizes this information.Figure3.3.8-1providesinterval,periodand approximate outage dates.Per IWE-2412(a),thefollowing examinationslistedinTableIWE-2500-1as deferrable totheendofthe inspectionintervalarenotrequiredtomeetthecriteriainTable IWE-2412-1:

IWE-2420(a) statesthatthe sequence of component and component support examinations establishedduringthefirstintervalshallberepeatedduringthe successive intervalstotheextentpractical.Entergywillselectand examine a majorityoftheClassMC components and component supports in accordancewiththiscriteria.However,EntergyhasadoptedCodeCaseN-624asapprovedin RegulatoryGuide1.147,whichstatesthatthe sequence of examinationsmaybe modifiedprovidedthe percentage of requirements ofTableIWE-2412-1aremet.CodeCaseN-624allowsthe sequence of examinations establishedduringthefirstintervaltobemodifiedbyfactorssuchas scaffolding erection, radiological concerns,insulationremovalorother considerations.

The Containment Inspection Engineer selects examinationsforagivenintervalandforagivenperiodin accordancewiththe requirementsof1OCFR50.55aandASMESection XI.Examination selections are documentedinthe IDDEALdatabase.The implementing organization determines the appropriate schedule for completionofthe examinationswithinagivenperiod.
