'.1.1.1.4.1 SPECIFICRULESFORCLASSIFICATION GeneralDesignCriterion 1of10CFR50,AppendixA,requiresthatnuclearpowerplantsystemsandcomponents important tosafetybedesigned, fabricated, erected,andtestedtoqualitystandards commensurate withtheimportance ofthesafetyfunctiontobeperformed.

Thesepressureretaining components offluidsystemsarepartofthereactorcoolantpressureboundary(RCPB),andotherfluidsystemsimportant tosafety,whererelianceisplacedonthesesystemsto:(1)preventormitigatetheconsequences ofaccidents andmalfunctions originating withintheRCPB,(2)permitshutdownofthereactorandmaintainitinasafeshutdowncondition, and;(3)retainradioactive material.

AtNMP2,QualityGroupAcomponents havebeenclassified asASMEHI,Division1,Class1inaccordance with10CFR50.2(v).

QualityGroupBcomponents havebeenclassified asASMEIII,Division1,Class2.QualityGroupCcomponents havebeenclassified asASMEIII,Division1,Class3.(Bothinaccordance withRegulatory Guide1.26guidelines.)

Therearetwonotableexceptions:

(1)Themainsteamlines&omtheoutermost containment isolation valvestotheturbinestopvalveswereneitherclassified norconstructed toASMEIII,Division1,Class2criteria.

Rather,theywereconstructed totheANSIB31.1Code,withaugmented qualityrequirements.

Theyhavebeenclassified asASMEXIClass2inthisprogram,andareinspected accordingly..

(2)TheReactorWaterCleanupSystempipinginthereactorbuilding, beyondtheoutermost isolation valve,althoughclassified as"notimportant tosafety,"wasnevertheless classified asASMEIII,Division1,Class3,andNMP2.IS1406 Rev.iSectioniPage2of16

Itretainsthatclassification (mostnotablyforrepair&replacement activities) inthisprogram.QualityGroupDcomponents arenotcategorically addressed inthisplan.However,singularqualityGroupDitemshavebeenincludedtosatisfyrelatedqualityinspection concerns.

USNRChasfound(inNUREG-1047, thesafetyevaluation reportrelatedtotheoperation ofNMP2)thatthesespecificrulesforclassification areinconformance withtheASMECodeandindustrystandards, theCommission's regulations, andtheguidancefoundinRG1.26.Theseclassifications ofASMEIIIClass1,2,or3havebeenassociated withitemsclassified asa"component" intheplant'sMasferEquipment List(MEL)thusallowingfortherapidacquisition ofCodeclassification byplantpersonnel.
