1.0 SUMMARYRADIOLOGICAL

ENVIRONMENTAL SURVEYJanuary1-December31,1997TheAnnualRadiological Environmental Operating Reportispublished inaccordance withSectionVloftheOffsiteDoseCalculation Manual,(ODCM).Thisreportdescribes theRadiological Environmental Monitoring Program,(REMP),anditsimplementation asrequiredbytheODCM.TheREMPisimplemented tomeasureradioactivity intheaquaticandterrestrial pathways.

TheaquaticpathwaysincludeLakeOntariofish,LakeOntariowater,andDeerCreekwater.Measurement resultsofthesamplesrepresenting thesepathwayscontained onlynaturalbackground radionuclides orlowconcentrations ofCs-137resulting frompastatmospheric nuclearweaponstesting.The1997resultswereconsistent withdataforthepastfiveyearsandexhibited noadversetrends.Terrestrial pathwayswerealsomonitored.

Theseincludedairborneparticulate andradioiodine, milk,foodproducts, anddirectradiation.

Analysisofterrestrial pathwaysdemonstrated nodetectable increaseinradiation levelsasaresultofplantoperation.

The1997resultswereconsistent withdataforthepastfiveyearsandexhibited noadversetrends.Theanalytical resultsfromthe1997Radiological Environmental Monitoring Programdemonstrate thattheoperation oftheRobertE.GinnaNuclearPowerStationhadnomeasurable radiological impactontheenvironment.

Theresultsalsodemonstrate thatoperation oftheplantdidnotresultinadosetothegeneralpopulation abovenaturalbackground levels.During1997,1454sampleswerecollected foranalysisbygrossbetacountingandgammaspectroscopy.

Theseincluded928airsamples,292watersamples,16fishsamples,7vegetation samples,58milksamples,and153thermoluminescent dosimeter measurements.

During1997therewere3deviations fromthesamplingscheduleforTLD'sand9fortritiumanalysis.

TheminimumnumberofsamplesrequiredinODCMTableV-1werecollected forallpathways.

Sampleswerecollected byGinnaStationchemistry personnel andanalyzedbytheJ.A.Fitzpatrick NuclearPowerPlantEnvironmental Laboratory.

Asummaryofthedatacollected indicating theresultsofalldataforindicator andcontrollocations isgiveninTable1-1.
