SUMMARY

OF MONITORING RESULTS 5 38 SummaryTheAnnual Radiological Environmental Operating Report presents data obtained through analyses of environmental samplescollected.forGrand Gulf Nuclear Station's (GGNS)Radiological EnvironmentalMonitoringProgram(REMP)fortheperiod January1,2014, through December 31,2014.Thisreport fulfills the requirementsofGGNSTechnical Specification 5.6.2.To supplementtheREMP,GGNS personnel installed duplicateTLDsandcollected duplicate samplesduringthereportingperiod.

Radiological Environmental Monitoring Program GGNS establishedtheREMPin1978priortothestation becoming operational(1985)toprovidedataon backgroundradiationand radioactivity normally presentinthearea.GGNS has continued to monitor the environmentbysamplingair,water, sediment,fishandfoodproducts,aswellas measuringradiationdirectly.GGNSalso samplesmilk,ifcommercialmilk productionoccurswithinfivemilesoftheplant.TheREMP includes sampling indicatorandcontrol locationswithinan18-mileradiusoftheplant.TheREMPutilizes indicator locations nearthesitetoshowany increasesorbuildupof radioactivitythatmightoccurduetostation operationandcontrol locations fartherawayfromthesitetoindicate naturally occurring background radioactivity.

GGNS personnel compare indicatorresultswithcontroland preoperationalresultstoassessanyimpactGGNS operationmighthaveonthe surrounding environment.In2014,GGNS personnel collected environmentalsamplesfor radiologicalanalysis.The monitoringresultsfor indicator locationswhencomparedtocontrol locations and previousstudiesshowthatGGNShasno significant effectonthelocal environment.Thereviewof 2014 monitoringdata,inmanycases,showed undetectableradiationlevelsinthe environmentandnear bac.kgroundlevelsin potential exposure pathways associatedwithGGNS.Harmful Effects or Irreversible.

Specifications Table 6.12.1-2;the analyticalresultsdidnot trigger any Radiological MonitoringProgramSpecialReports.

Radioactivity Not AttributabletoGGNS Over previousyears,theGGNSREMP detected radioactivity attributable to other sources.These.sourcesincludedthe Chinese nucleartestin1980andthe accidentatthe Chernobyl Nuclear PowerPlantin1986.In2011,theGGNSREMP detected radioactivityreleasedfrom 6

the Fukushima Dai-ichi Nuclear Power Plant followingtheMarch11,2011, Tohoku earthquake.In2014,the GGNS REMP detected no radioactivity attributable to other sources.Comparison to Federal and State Programs GGNS personnel compareREMPdatato federalandstate monitoring programs.Historically, the programsusedfor comparison includedtheU.S.Nuclear Regulatory Commission (NRC)Thermoluminescent Dosimeter(TLD)Direct Radiation Monitoring Networkandthe Mississippi State DepartmentofHealth(MSDH),Divisionof Radiological Health monitoring program.AlthoughtheNRCTLD Network Program was discontinuedin1998, these results compared favorably to thosefromthe GGNS REMP.TheMSDHandthe GGNSREMPhave similar monitoring requirements.

These programs include co-located air samplingandsharing samplemediasuchaswater, sediment,fishand food products.Both programs have obtained similarresults.The2014resultsoftheMSDH monitoring program compared favorablywiththeGGNSREMPresults.

Sample Deviations

MilkTheGGNS aDCM requires collectionofmilk samples if thereisa commercially available sourcewithin5miles(8km)oftheplant.In2014,theREMPdidnot include milk sampling because no commercial milk production occurredwithin5milesofGGNS.GGNS personnel instead collected vegetation samples to monitor the ingestionpathway,as specified in aDCM Specifications Table 6.12.1-1.*Required Lower Limit of Detection (LLD)Values Analytical lowerlimitof detection (LLD)valuesrequiredbythe aDCM specifications were achievedin2014werewithinthelimitsforallsamples.

Thermoluminescent DosimetersTLDM-50was retrieved wetinthe2nd quarter.TLDM-98wasretrievedwetinthe4th quarter.Similarly locatedTLDdata werereviewedandfound consistent with previousdata,with readings near background.Forthefirst quarterof2014,a higher than averageresultforTLDM-33wasreported.TLDM-33is considered a control location.Follow up inspectionbythevendor, Stanford Dosimetry, determined thattheTLDhadbeen damaged,andtheinitiallyreportedresultwasnotreliable.The sampling field notes show no indication of damagetoTLDM-33 during collection.

2.4 Sediment Sample Results Sedimentsampleswerecollectedfromtwo locations (indicatorandcontrol)andanalyzedforgammaemittingradionuclides.Inthisreportingperiod,plantrelatedgammaemitting radionuclideswerebelow detectable concentrationsintheupstream(control)location.

Cesium-137 was detectedatan average concentrationof39.4+/-25pCi/kginthe downstream(indicator)location.AreviewofREMPdatacollectedatthe downstreamlocationfrom1983through2013 indicates the Cesium-137 concentrationhasrangedfromlessthan detectableto300 pCi/Kg.Cesium-137 has previously been detectedintheupstream(control)location.

The presence of Cesium-137 is attributed to atmospheric weapons testing.Basedonreviewofresultsandhistoricaldata,plant operationshadno significantimpactonthispathwayduringthereportingperiod.

The differences were compared to the locations and assumptions used in calculations for compliance with the ODCM Limiting Condition for Operation 6.11.6 and 6.12.2.The locations and assumptions currently used in ODCM were determined more conservative thananyof the changes.Determinations from the most recentLandUse Census results are:*Because of downwind location and/or distance from thesite,inno casewillthe occupancyofan existing unoccupied residence cause any existing ODCM critical receptor calculation resultstobeless conservative.*No additional sampling locations are required as the onsite vegetation sampling location (SectorJ,0.4 miles)is more conservative than changes identifiedinthelanduse census.*Cattleareraised for human consumption (most notably in SectorsF,H,J,and K).GGNS uses the Grass/Cow/Meat pathway.*The milk pathway does not needtobe activated because no commercial dairy production is occurring within5miles,as referenced by ODCM Table 6.12.1-1.*SectorsM,N,P,andQare remote areas in which the primary use is hunting.Areas were surveyed by vehicle, aerial photographs, and interviews.

Gardens, regardlessofsize, were included in the census data Based on evaluation of theLandUse Census data, no ODCM revision is required.25 Table2.1 2014 Land Use Census Parameter Sector A*Sector B Sector C*Sector 0*I.Nearest Occupied a.Distance (mile)1.76 1.51 0.70 2.60 Residence b.Degreesfromtruenorth 351.6 23.7 42.3 60.8 II.Nearest Unoccupied a.Distance (mile)0.94 0.83 None None Residence (closer b.Degreesfromtruenorth 8.0 15.1 than occupied residence)

SUMMARY

Routine quality control (QC)testing was performed for dosimeters issued by the Environmental Dosimetry Company (EDC).During this annual period, 100%(72/72)ofthe individual dosimeters, evaluated against the EDC internal performance acceptance criteria (high-energy photons only), met the criterion for accuracy and 100%(72/72)met the criterion for precision (Table1).In addition, 100%(12/12)of the dosimeter sets evaluated against the internal tolerance limits met EDC acceptance criteria (Table2)and100%(6/6)of independent testing passed the performance criteria (Table 3).Trending graphs, which evaluate performance statistic for high-energy photon irradiations and co-located stations are given in Appendix A.Two assessments were performedin2014, one internal and one external.There were no findings.\-iv-I.INTRODUCTION The TLD systems at the Environmental Dosimetry Company (EDC)are calibrated and operated to ensure consistent and accurate evaluation of TLDs.The qualityofthe dosimetricresultsreported to EDC clients is ensured by in-house performance testing and independent performance testingbyEDC clients,andboth internal and client directed program assessments.

The purpose of the dosimetry quality assurance programisto provide performance documentation of the routine processingofEDC dosimeters.

Performance testing provides a statistical measure of the bias and precision of dosimetry processing against a reliable standard, whichinturn pointsoutany trends or performance changes.Two programsareused:A.QC Program Dosimetry quality control tests are performed on EDC Panasonic 814 Environmental dosimeters.

These tests include: (1)the in-house testing program coordinated by theEDCQA Officerand(2)independent test performbyEDC clients.In-house test are performedusingsix pairsof814 dosimeters, a pair is reportedasan individual resultandsix pairs are reportedasthe mean result.Results of these tests are described in this report.Excluded from this report are instrumentation checks.Although instrumentation checks represent an important aspectofthe quality assurance program, they are not included as process checks in this report.Instrumentation checks represent between 5-10%of the TLDs processed.

B.QA Program An internal assessment of dosimetry activities is conducted annually by the Quality Assurance Officer (Reference 1).The purpose of the assessmentisto review procedures, results, materials or components to identify opportunities to improve or enhance processes and/or services.II.PERFORMANCE EVALUATION CRITERIA A.Acceptance Criteria for Internal Evaluations1.Bias For each dosimeter tested, the measure of bias is the percent deviation of the reported result relative to the delivered exposure.The percent deviation relative to the delivered exposure is calculated as follows: where: H;=the corresponding reported exposure for the ith dosimeter (i.e., the reported exposure)Hi=the exposure delivered to the ith irradiated dosimeter (i.e., the delivered exposure)1of6 2.MeanBiasForeach group of test dosimeters,themeanbiasisthe average percent deviationofthe reported result relativetothe delivered exposure.The mean percent deviation relativetothe delivered exposure is calculated as follows: where:=the corresponding reported exposurefortheith dosimeter(Le.,the reported exposure)Hi=the exposure deliveredtotheith irradiated test dosimeter,(Le., the delivered exposure)n=the number of dosimetersinthetest group 3.PrecisionFora groupoftest dosimeters irradiatedtoa given exposure, the measure of precisionisthe percent deviation of individual results relativetothemean reported exposure.Atleasttwo values are requiredforthe determination of precision.

The measure of precisionforthe l" dosimeter is:(H'-R J l;H100 where:=the reported exposurefortheith dosimeter(Le.,the reported exposure).-(1)H=themean reported exposure;Le., H=nn=the number of dosimetersinthe test group 4.EDC Internal Tolerance Limits All evaluation criteria are takenfromthe"EDC Quality System Manual," (Reference 2).These criteriaareonly applied to individual test dosimeters irradiated withhigh-energyphotons (Cs-137)andareas follows for Panasonic Environmental dosimeters:

+/-15%forbiasand+/-12.8%for precision.

20f6 B.QC Investigation Criteria and Result Reporting EDC Quality System Manual (Reference 2)specifies when an investigation is required duetoaQC analysis thathasfailed theEDCbias criteria.The criteriaareas follows:1.No investigation is necessary when an individual QC result falls outsidetheQC performance criteria for accuracy.2.Investigations are initiated when the meanofaQC processing batch is outside the performance criterion for bias.C.Reporting of Environmental Dosimetry ResultstoEDC Customers 1.All resultsaretobe reportedina timely fashion.2.IftheQA Officer determines that an investigation is requiredfora process, the resultsshallbe issued as normal.IftheQCresults, prompting the investigation, have a meanbiasfrom the known of greater than+/-20 0/o, the resultsshallbe issuedwithanote indicating that theymaybe updatedinthefuture, pending resolutionofaQAissue.

3.Environmental dosimetry resultsdonot require updatingifthe investigation has shown that the mean bias between the original resultsandthe corrected results, based on applicable correction factorsfromthe investigation, does not exceed+/-20 0/0.III.DATA

SUMMARY

FOR ISSUANCE PERIOD JANUARY-DECEMBER 2014 A.General Discussion Results of performance tests conducted are summarized and discussedinthe following sections.Summariesofthe performance tests for the reporting period are given in Tables 1 through3and Figures 1 through 4.Table 1 provides a summary of individual dosimeter results evaluated against the EDC internal acceptance criteria for high-energy photons only.Duringthisperiod, 100%(72/72)ofthe individual dosimeters, evaluated against these criteria met the tolerance limits for accuracyand100%(72/72)met the criterion for precision.

A graphical interpretation is provided in Figures1and2.Table 2 providestheBias+Standard deviation results for each group(N=6)of dosimeters evaluated against the internal tolerance criteria.Overall, 100%(12/12)ofthe dosimeter sets evaluated against the internal tolerance performance criteria met these criteria.A graphical interpretation is provided in Figures 3 Table 3 presents the independent blind spike results for dosimeters processed during this annual period.All results passed the performance acceptance criterion.

GEL procures single-blind performance evaluation samples from Eckert&Ziegler Analytics to verify the analysis of sample matrices processedatGEL.Samples are receivedona quarterly basis.GEL's Third-Party Cross-Check Program provides environmental matrices encounteredina typical nuclear utility REMP.The Third-Party Cross-Check Program is intended to meet or exceed the inter-laboratory comparison program requirements discussedinNRC Regulatory Guide 4.15.Once performance evaluation samples have been prepared in accordancewiththe instructions providedbythePT provider, samples are managed and analyzedinthe same manner as environmental samples from GEL's clients.3.Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessmentofeachareaofthe laboratory is conducted in accordancewiththe pre-established schedule from Standard Operating Procedureforthe Conduct of Quality Audits, GL-QS-E-001.

The annual internal auditplanis reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's QA program.Internal audits are conducted at least annually in accordancewitha schedule approvedbythe Quality Systems Director.Supplieraudits'are contingentuponthe categorizationofthe supplier, and mayormaynotbe conducted priortotheuseofa supplier or subcontractor.

Type I suppliers and subcontractors, regardlessofhow they were initially qualified, are re-evaluated at least once every three years.In addition, prospectivecustomersaudit GEL during pre-contract audits.GEL hosts several external audits each yearforbothour clients and other programs.These programs include environmental monitoring, waste characterization, and radiobioassay.

The followinglistof programs may audit GEL at least annuallyorupto every three years dependingonthe program.*NELAC, National Environmental Laboratory Accreditation Program*DOECAP, U.S.Department of Energy Consolidated Audit Program*DOELAP, U.S.Department of Energy Laboratory Accreditation Program*DOEQSAS,U.S.
