Themathematical modelsusedtocalculate liquidandgaseousradioactive releaseswereobtainedfromtheNuclearRegulatory Commission's Regulatory Guide1.112,"Calculation ofReleasesofRadioactive Materials inGaseousandLiquidEffluents fromLight-Water-Cooled PowerReactors,"

April,1976andthereferenced documentspecifictoBoilingWaterReactors, NUREG-0016, April,1976.Nodesignchangeshavebeenmadetocauseincreases insourceterms.Anychangesinreleasesbetweenthisreportandthosepreviously reportedinthePetitionforConversion fromProvisional Operating LicensetoFull-Term Operating LicenseandEnvironmental Reportarecausedbythenewmathematical modelsandrevisedflowratesfortheliquidradioactive wastesystemtobeconsistent withRegulatory Guide1.112andNUREG-0016 andarenotcausedbyanychangetotheradioactive wastesystemcomponents themselves.

All'alculated doseratesresulting fromreleasesfromNineMilePointUnit1areshowntobewithinthedesignobjectives setforthinSectionsII.A,II.B,andII.Cof10CFR50AppendixI.Thecalculated dosestothepopulation residingwithinaradiusof*50milesare0.18man-remand6.3mn-thyroid-rem fromliquideffluents and0.23man-remand3.3man-thyroid-rem fromgaseouseffluents.

Cost-benefit analysesarepresented inaccordance withSectionII.Dof10CFR50AppendixI.Inperforming theseanalyses, radwasteaugmentswhicharejudgedtobethemostcosteffective havebeenconsidered, basedonthelistsofpotential augmentspresented inRegulatory Guide1.110,"Cost-Benefit AnalysisforRadwasteSystemsforLight-Water-Cooled NuclearPowerReactors,"

March,1976.Theseanalysesdemonstrate (Tables1.1.2-11and-12)thatadditional radwasteequipment ofreasonably demonstrated technology cannotbejustified ona.-cost-benefit basis.

.doseratesforindividual

pathways, from.whichtheTable1.1.1-1summaryhasbeenprepared, arepresented inTables1.1.1-2through1.1.1-12.Table1.1.1-2presentsthemaximumcalculated annualdosesfromnoblegaseffluents atthelocationofhighestdoseratelevel(6,300fteast,attheboundaryoftherestricted ea).Tables1.1.1-3through1.1.1-6presentmaximumcalculated doseratesintheadult,teen,childandinfantagegroupsresulting fromradioiodine andparticulate gaseouseffluents.

Thedoseratetothetotalbodyandvariousbodyorgansisreportedonthefollowing bases:Theindividuals, areassumedtobelocatedattheleastfavorable locationintheunrestricted area(i.e.,6,300fteast)relativetocontributions tothedoseratefrominhalation anddeposition ontheground.Theseindividuals areassumedtoconsumefreshleafyvegetables grownatthenearestactualvegetable garden(7,300fteast)andstoredvegetables fromthenearest.developed orchard(7,000ft.east).Theyarefurtherassumedtoconsumemeatfromthenearestactuallocationofmeatanimals(8,900fteast.-southeast)

.Theseareintentionally conservative assumptions.

.Theinfantthyroiddoseatthecowlocationisseentobethelargestcalculated value,ie.,0.75mrerq/yr.

Thecalculated maximumannualdosesforindividuals intheadult,teen,childandinfantagegroupsresulting fromliquideffluents arereportedinTables1.1.1-9through1.1.1-12.Forthepurposesoftheseanalyses, theseindividuals arecon-'ervatively assumedtoreceivecontributions totheirannualdosesfrom:ingestion*of potablewaterfromthenearestpublic 0

Thedosetothepopulation residingwithinaradiusof50milesiscalculated withtheplantsystemsandequipment asdescribed inSections1.2and2.1inthisreport.Thesepopulation doses'reforthesamebasecaseusedtocalculate theindividual dosesreportedinSection1.1.1.Theresulting population dosesarepresented inTable1.1.2-1.Theresultant population exposures are0.18and6.3man-remandman-thyroid-rem, respectively, fromliquideffluents and0.23and3.3man-remandman-thyroid-rem,respectively, fromgaseouseffluents.

Thesedataformthebasecasefromwhichthecost/benefit analysesareperformed.

Thepotential dosefromtheingestion ofaquaticinvertebrates isconsidered incomputing dosestoindividuals (seeTable1.1.1-9).However,thisisconsidered tobeaninconsequential pathwayrelativetolargepopulation groupsandisnotconsidered inthepopulation man-xemcalculations.

Noadditional significant pathwayswhichcouldcontribute 10percentormoretoeitherindividual orpopulation dosesareknowntoexistintheregionaroundthesite.Thefollowing radwasteaugmentsareconsidered intheseanalyses:
