1.0 Introduction

Thisreportissubmitted incompliance with10CFR50.36a(a)(2) andTechnical Specification 5.6.3.Itincludesasummaryofthequantities ofradioactive liquidandgaseouseffluents andsolidradwastereleasedfromWNP-2duringtheprevioustwelvemonthsofoperation.

Effluentdataissummarized onaquarterly basis.2.0LiquidEffluents Theradwasteliquideffluents werereleasedin"batchmode"duringthereporting period.Table2-0summarizes thenumberanddurationofbatchreleases, dilutionflowandcalculated maximumindividual doses.Theliquidbatchreleaseswererecirculated beforesampling.

Arepresentative samplewasobtainedandanalyzedforeachbatchrelease.Acomposite ofthebatchsamplesforeachmonthwasanalyzedfortritium,andacomposite sampleforeachquarterinwhichliquidsweredischarged wasanalyzedforstrontium 89,strontium 90,andiron55.Themethodsusedformeasuring thetotalradioactivity weregammaspectroscopy, liquidscintillation andproportional counting.

Table2-1providesasummation ofallliquidreleasesduringthisreporting period.TheaverageflowrateoftheColumbiaRiverduringJanuarythroughDecember1997was1.65E+05cubicfeetpersecond.Thepercentage ofMPClimitinTable2-1isbasedonthetotaloftheMPCfractions usingthenuclidesinTable2-2andtheconcentrations listedintheformer10CFR20,AppendixB,Table2,Column2.Doseswerecalculated usingtheLADTAPIIcomputercode,NUREG/CR-4013.

Estimated totalerrorsarelistedinTable2-1,andarepropagated fromindividual errorestimates ofsampleactivity, samplevolume,tankvolume,andtankhomogeneity.

Theestimated totalerrorswerecalculated byobtaining thesquarerootofthesumofthesquaresoftheindividual errorcontributions andmultiplying by1.96fora95percentconfidence level.Therewerenoliquideffluentmonitorswhichwereoutofserviceformorethan30days.Therewerenoabnormalreleases.
