The prcgram includes the collectionof samples fiom the environment and the determination of the concentations of radioactivematerials in the samples. Samples are takcn from stations in thc general area of the plant andfirom areas that should not be influenced by plaot operations. Material sampled includes air,atuosphoic moisfine, watetr, milt food cK)ps, soil, fislr, sedimelrt, and dircct radiation levels.Results from stntions neuthe plant are compared with concentations from contol locations andwith prcoperational measuremeirts to determine potential impacts of plant operations.The majority of eirvironmenal radioactivity measured by the program was dge to natqrallyoccuning radioactive materials or radionuclides commonly found in the elrvircnmelrt as a resultof atuospheric fallout and the operation of other nuclear facilities in the area low levels ofCesium (Cs)-137 wer* measured in soil, fisL and shoreline sediment samples. The Cs-137concentations werc consistent with the prcoperational monitoring pogram results and withIevels normally found in the envircnment as the result of past nuclear wealx)ilt testiug. Thefrllout from accidents at the Chernobyl plant in the tlkraine in 1986 and Frrtushima plant in "Japan in 201I may bave also contibuted to the low levels of Cs-137 measured in environmeotalsamples. Trace lwels oftitirm were detected in a limited uumber of atuosphcric moisturemmples. Tritium at concentations slighfly above the aoalytical decction limit was also detectedin a small number of ualer samples collected from Chickamauga Resemoir. These levels wouldnot rcpreseNrt a significant contibution to the radiation exposutt to members of the public.Tritirm was detected in onsite gtrormd water monitoring wells. The tritium was the result ofonsite gromd $raner contamioation from prwiotuly idqrtified andrepaired leaks in plantsystems. In addition, cobalt (Co)r60, Cs-137, and antimony (Sb)-125 were identified iu scdimentcollected from the onsite ponds. The level of activity measured in these onsite lcations woulduot prcsent a risk of exposurc to the general public.-l-INTRODUCTIONThis rcport descdbes and summarizes the results of radioactivity measurcm@ts made in thevicinity of WBN aud laboratory analyses of samples collected in the area- The measurements aremade to comply with the pquirements of l0 CFR 50, Appendix A Criterion 64 and l0 CFR 50,Appendix I, Section [V.8.2, IV.B.3 and tV.C and to determine poteatial effects on public healthand safety. This report satisfies the annual reporting requirements of WBN TechnicalSpecification 5.9.2 and Offsite Dose Calculation lvlanual (ODCM) Adoinistative Control 5.1.In addition to rcporting the data presoibed by specific requirementsi other infonuation isincluded to help correlate the significance of rcsults measured by this monitoring program to thelevels of environmental radiation resulting from ncurally occurring radioactive materials.Naturally Occunins and Backgrormd RadioactivityMost matedals in orn world today contain tace amounts ofnaturally occuning radioactivity.Potassium (K)40, with a half-life of 1.3 billion yeaf,s, is one ofthe major types of radioactivematerials formd naturally in our environment Approximately 0.01 perccot of alt potassium isradioactive potassium-40. Other examples of naturally occuni4g radioactive mafedals arcberyllium (Be)-7, bismuth (Bi)"212 atd2l4,lead (Pb)-212 and 214, thallis6 (n)-20E, actinium(Ac)-228,uranftrm (U)"238 and 235, thorium (Th)-234, radium (Ra)-226, radon (Ra)-222 and220, wllrcln (C) -14, aod hydrogen (tt)-3 (generally calld tititm). These naturally occuningradioactive materials are in &e soil, our foo4 ou drinking watcr, and our bodies. The radiationfromthese materials makes up apartofthe low-level natural backgpundradiation Theremainder of the Datural backgrcrmd radiation results from cosmic rays.It is possible to get an idea of the relative hazard of differqrt types of radiation sources byevduatitg the amount of radiation the U.S. population rcceives from each general type ofradiation source. The information below is primuily adaptd ftom Refwnces 2 and 3.-)-ta u.s.

Thisindicates that nuclear plant operations normally rezult in a population radiation dose equivalentwhich ig insignificant compared to that which rcsults from nanrral background radiation. Itshould be noted that the use of radiation and radioactive materials for medical uses has resultedin a similar effective dose equivalent to the U.S. population as tbat catrsed by natual backgrcuudcomic and terrestial radiation.Electic Power MuctionNuclear po\rEr plants are similar in many rcspects to conventional coal buming (or other fossilfuel) electrical generating ptants. The basic psocess behind electrical povrcr production in bothtyryes of plants is tbat fuel is usd to heat water to prod,rce stcam which prcvides the force to tumturbines aud gencrators. In a nuclear power planq the fuel is uranium and heat is poduced in ttrereactor through the fission of the uranium. Nuclear plants include mey complex systems tocontrrol the nuclear fission process and to safegrrard against the possibility of reactor malfimctioaThe nuclear reactions produce radionuclides commonly refErred to as fission and activationproducts. Very small aoormts ofthese fission aad actination products re reteased into the plantsystems. This radioactive material can be tansportd throtrghout plant systems aod some of itreleased to the environment. The nuclear reactions produce radionuclides commonly refetred to as fission and activatiouproducts. Very small amounts of these fission and activationproducts are released into the plantsystems. This radioactive material can be tanspofted tbrouglout plant systc,ms and some of itreleased to the elrvironment.Paths thrcugh which radioactivity finom a nuclearpower plaut is routinely released are monitored.Liquid and gaseous efluent monitors record the radiation levels for each release. Thesemonitors also provide alarm mecbanisxns to p,rompt termination of any rclcase above limits.Releases are monitored at the onsite points of rclease and throtrgh the radiological environm:ntalmonitoring program which measunes the envirjnmental radiation in areas arormd the plant Inthis way, the release of radioactive matcrials from the plant is tightly confiolle4 and verificationis provided that the public is not exposed to significant levels of radiatibn or radioactivematerials as the result of plant operations.The WBN ODCM, which describes the program required by the plant Technical Specifications,prescribes limits for the releasc of radioactive effluents, as well as limits for doscs to the generalpublic ftom the release of these efluents.The dose to a member of the general public ftom radioactive materials rcteased to uorestrictedanEas, as given iu Nuclear Regulatory Commission (NRC) guidelines and the ODCM, is limitedas follows:Liquid EffiuentsTotal bodyAny organ<3 mrem/Year<10 mrern/YearCraseous EffluentsNoble gases:Crammaradiation <10 millirad (mradlYearBeta radiation <20 mrad/YearParticulates:Any organ4-<15 mrem/Year The EPA limits for the total dose to the public in the vicinity of a nuclear power plan!established inthe Environmental Dose Standard of CI CFR 190, are as follows:Total body <25 mrem/yearThyroid !75 mrem/yearAny other organ <25 rnrem/yearAppendix B to l0 CFR 20 presents annual average limits for thc conce,ntations of radioactivematerials releasd in gaseous and liquid efluents at the bormdary of the mrcsfticted arcas.Table I of this report prcsents the annual average concentation limits for the pnncipalradionuclides associarcd with nuclear power plant efluents. The table also prese,nts (1) theconcentrations of radioactive materials in the environment which would require a spocial reportto the NRC aod (2) the detection limits for measued radionculides. It should be noted that thelevels of radioactive materials measured in the environme,nt are tpically below or only slightlyabove the lower limit of detection. SITE/PLAI{T DESCRIPTIONThe WBN site is locatcd in Rhea @rmty, Tennessee, on the west bank of the Te,nnessee River atTennessee River Mle (TRM) 528. Figrre I shows the site in relation to other TVA projects.The WBN sirc, containing approximately 1770 acres on Chickamauga Iake, is approximately2 miles south of the Wafb Bar Dam and approximately 3t miles north-norlteast of TVA'sSequoyah Nuclear Ptant (SQN) site. Also looated within the neserrration are the Wafis Bar Damand Hydro-Electric Plant the Watts Bar Steam Plant (not in operation), the TVA Ceotallvlaintenance Facility, and the Watts Bar Resort ArcaApproximdely 16,000 people live within l0 miles of the WBN site. More thm 80 percent ofthese live beturecn 5 and 10 rnilss fr'o* the sirc. Two smell towns, Spnng City and Degatur, arcIocated in this area Spring City, with a population of approximately 2,200,is uorthwest andnor&-northwest from the srtg while Decatur, with about 1,500 people, is sotrth and south-southwest from the plant The remainder ofthe area within l0 miles of thc sie is sparselypopulatc4 consisting primarily of mall farms and individual residences.The area betrreen I0 and 50 miles from the sirc includes portions of the cities of Cbattanoogaand lfuoxville. The largest rnban concentatioa in this area is the crty of Chdtanooga, located tothe southwest and south-sordhwest The city of Cbattanooga has apopulation of about 170,000,with approximately 80 perceot located between 40 and 50 miles from the sirc and the remainderlocated beyond 50 miles. The city of Ifuoxville is located to the east-northeasg with not moretha' 10 percent of its 185,000 plus people living within 50 miles of the site. Three smattel urbanareas of greater than 20,000 people are located betw*en 30 and 40 miles from the site. OakRidge is approximately 40 miles to the northeast, th* twin citics of Alcoa and Maryville uelocated 45 to 50 miles to the east-northeast, and Cleveland is located about 30 miles to the soutt.Chiclcamarga Reservoir is one of a series of highly contolled multiple-use reservoirs whoseprimary us*s are flood contol, navigation, and the generation of electric power. Secondaryus*s include industrial and public water zupply and naste disposal, fishin& aod recreationPublic acce$ araas, boat docks, and residential suMivisions have been developed along thereservoir shorelinc. WBN consists of two pressudzed wafisr reactors. WBN Unit I received a low power operatinglicense (NPF-20) onNovember 9, 1995 and achieved iDitiat lriticality inJanuary 1996. The fullpowet operating license (MF-90) was received on February 7,7996. Commercial operation wasachieved May 25,1996. WBN Unit 2 was defercd October 24,20N, in accordance with theguidance in Creneric Letter 87-15, *Policy Statement on Deferred Plants.' On August 3,2007,TVA ptovided ootice of its intent to reactivate and complete constnrction of WBN Unit 2. WBNUnit 2 resumed constnrction in late 2OO7,and orpects to complete consfruction and request anoperating license by December 2015.-7' RADIOLOGICAL E}.IVIRONMENTAL MoNIToRING PRoGRAI\{Most of the radiation and radioactivity generared in anuclearpowerreac.tor is contained withinthe reaotor systems. Plant efluent radiation monitors are designed to monitor radionuclidesreleased to the environment. Environmental monitoring is a final verification tbat the systemsare performing as planned. The monitoring program is designed to monitor the pathwaysbetween tbc plant and ths people in the immediate vicinity of the plant Sample types are chos*nso thm the potelrtial for detection of radioactivity in the environment will be morimized. TheRadiological Environmental Monitoring Program (RElrP) and sampling locations for WBN areouflined in Appendix A.There are two primary parhways by which radioactivity can move thrcugh the environment tohumans: air and water (see Figure 2). The air pathway can b s4arat*d into trro comlrcnents:the direct (airborne) pathuray and the indirect (gormd or terresnial) pathnay. The directairbome pathway consists of direct radiation and inhalation by htrmans. ID th* ter*sfrialpathway, radioactive materials may be depositcd on the glotmd or on plants and subsequcntlyingested by animalg and/orhumans. Hum; exposlrre through the liquidpdhway may resultfrom drinking $rater, eating fislU or by direct erryosur* at the shoreline. The tlpes of samplescollected in this prcgram are designed to monitor these pattrwaysA number of factors were considered in determining the locations for collecting environmentalsamples. The locdions for the tuogphcrio monitoring stations were determined from a cdticalpathuay analysis based on weafher patterns, dose projections, populdion disfribution, and landllse. T*rrestrial sampling stations were selected after reviewing such 'irgs as the locations ofdairy nnimals and gardens in conjrmction with the air pathrvay aoalysis. Liquid pathway stationswere selected basd on dose projections, water rse information, and availability qf media sgch asfish and sediment. Table A-2 (Appendix A, Table 2: This notation system is used for all tablesand figrres glven inthc appendices.) lists the sampling stations andthetlpes of samplescollected from each. Modifications made in the WBN REMP h 2013 are reported inAppcndix B. Deviations o@ur in the monitoriug prcgram due to equipment problems with automatic samplingsystems, and/or sample unavailability. Deviations to the sampling prcgram during 2013 areincluded in Appendix C.To determine the amotmt of radioaotivity in the eirvironment prior to the operdion of WBN, apreoperatioual radiologioal environmental monitoring progrm was initiated in December 1976and operated thugh December 31, 1995. Mpasurements of the same tlpes of iadioactivemarcrials thd are measurd currently were assessed during the preoperdional phase to establishnomal backgrcrmd levels for various radionuclides in the envitonment Dufug the 1950s,1960q and 1970q tuospheric nuolear weapons testing released radioactive matedal to theelrvironment causing fluctuations in backgrcund radiation levels. Ifuowlillge of preoristingradionuclidc patterns inthc environmentpermits adetermination, tbrcughcomparisonandThe determination of envircnmental impact during the operating phase also considers theprcsense of control stations that have been established in the environment Results ofenvironmental samples taken at conful stations (frr from the plant) are compared with thosefrom indicator strtions (nar the plant) to aid in the determination of the impaets fi,om WBNoperationThe s"mple analysis is performed by the Tennessee Valley Authority's (fVA's) EnvironmartalRadiological Monitoring and Instnrmentation (ERI\{&I) group located atthe WesternAreaRadiological Labontory (WARf) in Muscle Shoals, Alabama, except forthestrontirm (Sr)-89, 90 analysis of soil samples which is performed by a conEact lahratory.Analyses ae oonducted in accordance with written and approved procedur,es and are based on .accepted methods. A summary of the analysis techniqucs and methodolory is presarted inAppendix D. Datatables summarizingthe sample analysis results are pteselrted inAppendix H.The Data Supplement to this report contains the results of all measurements made as a part ofthis program. The radiation dctection devices and analysis methods used to determine the radionuclide contentof samples collectcd in the environment arc very se,nsitive to small amounts of radioactivity. Thesensitivity of the measuremeirt prooess is defined h tcrms ofthe lower limit of detection (LLD).A description of the nominal LLDs fot the ERM&I laboratory is presented in Appendix E.Tbe ERM&I laboratory operates under a comprehensive quality assnance/quality contolprogram to monitor laboratory performance throughout the year. The program is intended todetec't any problems in the mesuement prccess as soon as possible so thcy can be cotrected.This pmogram includes equipment chects to ensure tbat the radiation detectioa insfitments areworking properly and the aoalysis of quality contol samples which are included alongsidercutine environmental samples. To provide for interlaboratory comprison prograq thelaboratory participatcs in an environmental cmoss-check program administercd by Eckert and7-regler Aoalytics. A completc description of the prcgram is presented in Appdix F.- l0-DIRECT RADIATION MONITORINGDircct radiation levels are measured at various monitoring points around the plant site.These measurements include contibrtions from cosmic radiation, radioactivity in thegroun4 frllout fiom amospheric nuclear weapoffr tests coaducted in the pas( and anyradioactivity that may be prese,nt as a result of plant operdions. Because of the relativelylarge variations in backgrouud radiation as compared to the small levels Aom the pla4contibutions from the plant may be difficult to distinguish.Measurement TechniquesThe Landauer Inlight environmental dosimeter is used in thc radiological environmentalmonitoring prcgram for the measurement of direct radiation. This dosimetEr containsfou ele,me,nts consisting of alurninum oxide det*ctors with open windows as well as plastic andoopper fiIt*rs. The dosimeter is processed using optically stimulated luminescence (OSL)technology to determine tbc amount of radiation o(posure.The dosimeters are placed approximafiely one meter above the grormd, with two at eaohmonitoriog location. Si:rteen monitoring points are located atound the plant near the sitebouudary, one location in each ofthe 16 compass spctotr. One monitoring point is alsolocaied in each of the 16 compass sectors at a distance of appnoximately four to five milesfromthe plaatDosimeters are also placd at additional monitoring locations out to approximately15 miles ftom the site. The dosimetcn are exchanged every tbree montbs. The dosimeters arcseirt to Landauer Inlight for processing and rezults repoting. The values are conected fortrarsit and shielded background exposur*. An average ofthe two dosimaer results iscalculated for each monitoring point. The system meets or exceeds the performancespecifications outlined inAmericaoNational Standads Institfie (A].ISD N545-1975 and HealthPhysics Society (IPS) f,trafr Standard N13.29 for environmental applications of dosimeters.WBN Technical Specification s.g.z,Annual Radiological Environmeirtal Operanng Reporqrequires that the AnilEl Radiological Environmental Op*rating Report identi$ TLD resula thatrcpres*nt collocatcd dosimeters in relation to the NRC TLD program and the er(posure period-1 l-associated with each result. The NRC collocated TLD program was terminated by the NRC atthe end of 1997,therefore, therc are no TLD rezults that represe,lrt collocated dosimeters includedin this reportksultsThe results for eirvironmental dosimetq mgasruements are normalized to a standardquarter (91.25 days or 2190 hours). The monitoring locations are grouped according tothe distance ftom the plant The first goup consists of all monitonng points within2 miles of the plant The second group is made up of all locations grcater than 2 miles fromthe planl Past dats have shorvn tbat the average results fiom thc locations more than2 miles fiom the plant are essentially the same. Therefore, for prrposes of this r*port,monitoring points 2 miles or less from the plantae identified as'otrsite" stations andlocations greater than 2 miles are considered *offsite.'The qtrarterly gamma radiation lwels detennined from the dosimeters deployed arormdWBN in 2013 are summarized in Table H-1. The ocposures are measrr,ed inmilliroentgens (mR). For purposes of this report one mX! one mrem and one mradarc assumed to bentmerically equivalentThe rouaded average annual exlrosues, as measured in 2013, are Sown below. Forcomparison purlroses, the average dircct radiation measuemsrts made in thepreoperational phase of the monitoring program arc also shown.Annral WBN AverageDirect Radiation LevelsmR/YearOnsite StationsOffsite Stations20t363s8PreoperationalAverage6s57'12-The data in Table H-I indicates tbat the averagc quarterly dircct radiation levels at theWBN onsite stntions are approximately 1.3 mR/quartcr higher than'levels at the oftitestations. This difference is consistent with levels measured for the preoperation andconsfruction phases of TVA nuclear power plant sircs where the average levels onsitewer,e slightly hig[er thm levels oftite. Figue H-l compares plots of the data ftom the onsitestations with those fiom the oftite stations over the period from 1977 throrrgh 2013. The newIandauer Inlight Optically Stimulated Luminescence (OSL) dosimeters were deployed since2007 replacing the Paoasonic LJD-814 dosimeters used dudng the previous years.The data in Table H-2 contains the results of the individtnl monitoring stations. The resultsreported in 2013 are consiste,nt with direct radidion levels id*otifid at locations which are notinflueirced by the operation of WBN. There is no indication that WBN activities increased thebackgrormd radiation levels normally observed in thc areas sunormding the plaot. ATMOSPHERIC MONITORINGThe ahosphedc monitoring netrrork is divided into three grcups identified as local, perimeter,and remotc. Four local air monitoring stations arc located on or adjaceirt to the plant site in thegenenal directions of greatest wind frequency. Four perimeter air monitoring stations are locatedbetween 6 to 1l miles fiom the plant, and two air monitors are located out to 15 miles and usedas oontrol or baseline stations. The monitoring program and the locations of monitoriqg statioDsare identified in the tables and figures of Appendix A.Results from the analysis of samples in the atuospheric pathway are preseirtcd in Tables H-3,H-4, and H-5. Radioactivity levels identified in this reporting pedod are consistcnt withbackground and preoperational program data Thcre is no indication of an increase inffiospheric radioactivity as a restrlt of WBN operations.Sample Collection and AnalysisAir particutates are collest*d by continuously sampling air at a flow rate of approximately2 cubio feet per Eirute (cfu) through a 2-inch glass fiber filter. Thc sampling system consists ofapurnp, amagnchelic gauge formeasrring the drcp in pressure acnoslttbe system, and a dry gasmeter to measure the total volume of air sampled" This system is housed in a buildingapproximately 2 feetby 3 fea by 4 feet- The filter is contained in a sampling head mormtpd onthe outside of the monitoring hdlding. The filter is replaced weekly. Each filter is analyzed forgross beta activity about 3 days after collection to allow time for the radon darrghtcrs to decay.Every 4 wecks composites of the filt*rs fiom each location are ualyzed by gamma sptroscopy.Craseous radioiodine is sampled using acommercially available crtidge oontainingTriahylenediamine (TEDA)-imprregnated chucoal. This system is designed to collect iodine inboth the elemental form and as organic compormds. The cartidge is located in the samesampling head as the air particulate filter and is dormstcam of the particulate filter. Thecutridge is e;hanged at the same time as the particulate filter and samples the same volume of air.Each cartridge is analyzed for I-l3l by gamma specfioscopy analysis.'14' Atuospheric moisture sampling is conducted by pulling air at a constant flow ratc througb acohmn loaded with approximately 400 grams of silica gel. Every two weeks, the column isorchanged oa the sampler. The atuospheric moisture is removed from silica gel by heating andeallzed fortritium.ResultsThe results from the analysis of air particul66 samPles are summarired in Table H-3. Gross betaactivity in 2013 was consistelrt with levels reported inprevious years. The average gross betaastivity measued for air particulate samples was 0.021 pCi/m3. The annual avemges of thegross beta activity in air particulate filters at thrcse stations for the friod 197?-2013 arepr*s*Nil.ed in Figrre H-2. Increased levels due to fallout from atmospheric nuclear wealxlnstesting are evident in the years prior to 1981 and a small iacrcase fiom the Chcrnobyl accidelrtcan be seen in 1986. These patterns are consistent with data from monitoring programsconducted by TVA at other nuclear power plant constnraion sites. Comparison with the samedata for the preoperational period of 1990-1995 indicates tbat the aonual av*ragc gross betaactivity for air particulaes as measured in the 2013 monitoring program was consistent with thepmeoperatioDal data"Only natural radioagtive materials were identified by the monthly s;auupa spcchal analysis of theair particulafe samples. As shown in Table H-4, I-l3l was not detected in any chrooal cartidgesamples collected in 2013.The results for atmospheric moistrne sampling are reportcd in Table H-5. Tritium was measuredin a limitcd number of amospheric moisture samples at levels slightly above the nominal LLDvalue of 3.0 pCi/m3. These values were consistent with prwiously reported data TERRESTRIAL MOMTORINGTercstial monitoring is accomplished by collecting samples of environmenhl media that maytansport radioactive material from the atuosphe,re to humans. For e:rample, radioactive materialmay be depositcd on a vegetable gaden and be ingested along with &e vegetables or it may bedeposited onpasture grass where dairy catle are grazing. When the cow ingests the radioactivematerial, some of it may b* transfer*d to the milk and consumed by humans who ddnk the milkTherefore, samples sf millc, soil, and food crops are collected and analyzed to determinepotential impads ftom exposure througb this pathway. The from the analysis of thesesamples arc shown in Tables H-6 tbrcugb H-12.A land use survey is conducted annually benreen April and Octobq to identify the location ofthe nearest nilk eimal, &e nearest residence, and the nearcst garden of greater than500 square feet productng fresh lea$ vegaables in each of 16 meteorological sectors within adistance of 5 miles ft,om the plant. This land use survey satisfies the requirements l0 CFR 50,Appmdix I, Section fV.B.3. From data produced by the land use suney, radiation doses arcprojected for individuals living nearthe plant. Doses from air submersion re calculated forthencarest residence in each s@tor, while doses from ddnking milk or eating foods produced nearthe plant are calculated for the areas with milk-producing nnimnls and gardenq respeotively.These dose projections are h5ryothetical erfiemes and do not represeirt affid doses to the generalpublic. The results of the 2013 land use survey arc preselrted in Appendix G.Samole Collection and AnalvsisMiIk samples are collected everytwo wccks from two indicator dairies and Aom atleast oneconhol dairy. Milk samples ale ptaced on ice for fiansport to the radioanalytical laboratory.A specific analysis for I-l3l and a gamma sp*ctal aoalysis are performed on cach sample andonoe per quarter samples are analyzed for Sr-89 and Sr-90.-l 6-The monitoring program includes a provision for sampliag of vegetatiou from locations whememilk is being produced 41d yfiql milk sampling cannot be conducted.

A timer tums on the system d, container. A one-gallon sample is removed from the container at 4-week inteivals and thercmaining water is discarded. Each sample is analped for gamma+rnitting radionculides, gtossbeta activity, and tritiuur.Sgmples are also collectcd by an automatic sampling system at the firsttwo downstneam driokingwater intakes. These samples are collected in the sane menn*tr as the $dace water samples.These monthly samples are analy.d for gamma-emitting radionuclidesi gross beta aotivity, andtritium. The samples collectcd by the automatic sampling device are taken directly from theriver at the intake stRrcture. Since these samples are unteated water collected at plant intake,the upsteam surface nder sample is used as a contol sample for drinking watsr.-t9-Grcund wateris sampled fiom one onsite well down gradientfrom the planq one onsite well upgradient ftom the plaog aod four additional onsite ground urater monitoring wells located alongundcrgrcund discharge lines. The onsite wells are sampled with a continuous sampling system.A compositc sample is collected from the onsite wells every four weeks and analped forgamme+rnitting radionuclides, gr)ss beta activity, and tritium content In addition, a gabsample is collectcd evety forn weeks ftom a private well in ao area rmaffected by WBN. Thegfab sample is also analyzed for gross beta activity, gamma-emitting radionuclides, and fortritium.Sanples of commercial and game fish qpecies are collected semiarnuab from each oftworeservoirs: the reservoir on uihich the plaot is located (Chickaoauga Reservoir) and theupstcam rescrvoir (Watts Bar Reservoir). The samples are collected usit g a combination ofneting techniques md elechofishing. The ODCM specifies analysis ofthe edible portion ofthefish. To comply with this requiremen! filleted portions are taken from seve,lal fish of eachspecies. The samples are analyzed by samma spectroscopy.Samples of shoreline sediment art collected fiom recreation areas in the vicinity ofthe plant.The samples are drieq goun4 and aoalped by gam-a qpectroscopy.Samples of sediment are also collected from the onsite ponds. A total of five samples werecollected in2013. The samples arc &ie4 g!ou4 and analyzed by gamma spectroscopy.ResultsChoss beta activity was detectable above the nominal LLD in most oftte surface nder samples.The gross beta concentatiom averaged 3.6 pCinit*r in dovvnsheam (indicaior) samples frd,2.7pCinitq in upstream (control) samples. These levels were consistelrt with res;ults found duringthe preoperational monitoring program. Tritium at a level slightly above the nominal LLD valueunas detected in one surface water sample. The titium concentation was 279 fiifhrc;r whiohwas significantly below the EPA drinking water limit of 20,000 pCi/titer. Low levels of Cs-137were detected in trro surfape water semJrles. An investigation rilas condtrcted that det*rminedthat the Cs-t37 was duc to external contamination of the samples. The investigatioD walrdocumented in Problem Evaluation Report (PER) 727222. A summary table of the results for surface nrater samples is shown in Table H-13. The annual average gross baa activity in s,rfrcewater samples forthe period 1977 through 2013 areapresenrcd in Figure H-4.No fission or activation products were identified by the gauum analysis of drinking watcrsamples &om either of two dorrylsheam monitoring locations. Average gross beb activity atdownstream (indicator) stations uas 2.8 pCi/litcr aod the average for gpstream (confol) stationwas also 2.7 llCJlhtrr. Iow levels of titium were detected in two samples collected ft,om thetwo downsfieam public water sampling locations. These titium levels were sictrificantly belowthe EPA ddnking water limit of 20,000 pCi/liter. The rcsults are shom in Table H-14. Trendplots ofthe gross beta activity in drinking water samples from 1977 thrcugh 2013 are presentcdin Figtue H-5.Thc gamma isotopic analysis of ground watcr samples identified only ndrrally occgrringradionuclides. Crross beta concenfiations in samples from tbe ousite indicator locations averaged3.1 pCi/liter. The average gross beta astivity for samples from the contol locations was2.5 fiitlitfi. Tritium was detected in samples from the onsite monitoring wells locatcd nearplant discharge lines. The titium in onsite gouod water was the result of previously id*ntifiedleaks ftrom plant systems. Repairs were made to resolve the leaks but the plume of contaminatedgpund wat*r continues to move slowly across the sitc tourad the river. The highest titiumconcentation in samples from these monitoring locations was 1,510 pCi/liter. There was notitium daected inthe onsite up gradientwell orthe oftite gormdwatermonitoring location-The results are presented in Table H-15.Measurable lerrels of Cs-I37 were identified in a total oftbree fish samplcs. The maximumCs-137 conccntation was 0.05 pCi/g measured in commercial fish collec.ted at the upstreamlocation Other radioisotopes found in fish were naturally occuning, with the most notable beingK-40. The results are summarized in Tables H-16 and H-17. Trend plots ofthe annual averagecs-137 concqrtations mcasured in fish samples arc presented in Figue H-6. TheCs-137 activities are consistent with preoperational results produced by fallout or efluents ftomother nuclear facilities.ab Cs-137 consistent with the concentations present in the envircnment as the result of past nuclearweapons testing or other nuclear operations in the arca was measur*d in atotal of three shorelinesediment sarrples. The rezults forthe analysis of shorcline sediment is presented in Table H-18.Trend plots of the average concentatioo of Cs-137 in shoreline sediment ue presented in FigrreH-7.Consistent with previous monitoring conducted for the onsite pon&, Cs-137 $as detestcd in thesedime,nt samples. The average ofthe Cs-I37 levels measured in sediment from the onsite pondswas 0.07 pcrtp. In addition, Co-60 and Sb-125 wene also detected in some ofthe samplescollected from the onsite ponds. The resul* for the analysis of pond sediment sapples areprovided in Table H-19. Since these radionuclides wer* present in relatirrclylow concentationsaud confined to the ponds located iD the owner controlled area not opeo to the ge,lreral public, thepr*s*nce ofthese radionuclides would not repreent an iucreased risk of orposrre to the gcneralpublic. ASSESSMENT A}.ID EVALUATIONPotential doses to the public arc estimated from measured efluents using computer models.These models were developed by TVA and are based on guidance provided by the I.IRC inRegulatory Guide 1.109 for aeterrrining the potential dose to individtrals and populations livingin the vicinity oftbe plant The results ofthe efluent dose calculations are reportcd in theAnnual Radiological Efluent Release Report" The doses calculated are a rqnesentation of thedose to alnaximum cxposed individual." Some of the frcton usd in these calculations (zuchas ingestionraf*s) are ma,rimum expected values rvhichwilltendto overestimde &e dose to the'tlpothetical'person Thecalculatedmardmumdoseduetoplaoteffueirtsaresmallfuctiousofthe applicable r*gulatory limits. In reality, the expected dose to actual individuals issignificantly lower.Based on the very low concentrations of radionuclides actually prescnt in tbe plant eflucnb,radioactivity levels Eeasured in the environment as result of plant operations, are expected to benegligible. Tbe results for the radiological environmental monitoring couduc'ted for WBN 2013operations confirm this orpectatiouResultsAs statcd eulier in this rcpor! the estimated increase in radiation dose equivalentto the generalpublic rcsulting from the operation of WBN is insignifioant when comparcd to thedose fromnatral background radiation The resrlb fiom each environmental sample are compared withthe conceirtrations from the corresponding control stntions and appropriatc prpoperational andbackground data to determine influences from the plant During this report perio4 Cs"137 wasdetected in sboreline sediment, soil, and fsh colected for the WBN program. The Cs-137conceirtrations were consistent with levels mcalrured during the preoperational monitoringprcgram. The low levels of tritium measurpd in water samples fiom Chickmauga Rescrvoirrepresented conoentations rhat were a small fraction of the EPA drinking watet limii.The levels of tritium det*ctcd in the onsite ground water monitoring wells aod the radionuolidesmeasu*d in samples of sediment from the onsite ponds do not reprcsent an incresd risk ofa3-exposurc to the public. These radionuolides were limited to the owner contnolled area aod wouldnot present ao exposurc pathway for the genetal public,:I Conclusions, tt is concluded from the above analysis of environmental samples aad ftom the tnend plotsp,r*s*nted in Appendix H, that exposur* to mcmbers of the general public which may have been:: attributable to WBN is negligible. The radioactivity rcported herein is pimarily the result ofi fallout or natural background.

Air particulate filt*rs are oouuted directly in a shallowplanchetThe specffic analysis of I-l3l in milk is pcrformed by first isolati'g and puri$ing the iodine byradiochemical separationand then counting the finalprecipitae on abeta-gamma coincideircecounting sptem. The normal count time is 50 minutes. With the beta-gamma coincidencccounting system, backgrouDd cormts are virtually eliminated and or&emely low lwels of activitycan be detected.After a radiochemical separation, milk samples analyzrdfor Sr-89, 90 are counted on a lowbackground baa counting system. The sample is countd a second time after a74ay ingroui'thpedod. From the two @unts, the Sr-89 and Sr-90 concentatiout can bc determinedWater samples are analyzed for trititrm content by first distilling a portion of the sample and the,ncormting by liquid scintillation. A commercially available scintillation cocktail is used.Cramma analyses are performed in various cor.uting geometies on the sample tlpe andvolume. All gamma counts are obtained with germanium tlpe detectors interfaced wirh a highresolution ganna specfuoscopy system The charcoal cartridges usedto sample garcoun radioiodine are analyzedby gamma specfioscopyusing a high resolution gamma spechoscopy systcm with gemadlm detectonr.Afuospheric moisture samples are collected on silica gel fiom a metered air flow. The moisture isreleased from the silica gel by heating and aportion ofthe distillate is cormted by liquidscintillation for tritium rsing commercially available scintillation cochail.The necessary efficiency values, weight-efficiency surves, and geometry tabtes are established udmaintaiDed on each detector and cotrnting system. A series of daily aod pedodic quality contolchecks are performed to monitor counting instnrmelrtation System logbooks and controt cbarts ueused to document the results of the quality contol checks.47-APPEI\TDIXENOMINAL LOWER LIMITS OF DETECTION Appendix ENopdnal Lower Limits of DetgctionA numbs of factors influence the Iower Limit of Detection (LLD), including sanple size, cormttine,counting efficiencn chemical plocesses, radioactive decay frctors, and interfering isotopes encounteredin the sample. The most probable values for thesc factors have been evaluated for the various analysespedormed in the environmental monitoring prcgrm. The nominal LLDs are calculted in accordancewitti the methodologr prescribed in the ODCM, are presented inTable E-1.

This program includes the use of writren, appoved procedures inperforming the wor\ provisions for stafftraining and certification, interDal self assessmeots ofptogram performance, atrdits by various orternal organizetisas, and a laboratoryquality control program.The quality contol program employedby the radioanalytical labordory is designedto ensuretbat the sampling and analysis prccess is working as intenied. The prognm inchades equipmelrtchecks md the analysis of quality contol som,ples along with routine samples. Instrumentqualityconfiolchecksincludebaokgroundcountrate aadcormtsreproducibility. Inadditiontothese two geireral checkq other quality contol check are performed on the variety of detectorsusd in the laboratory. The exact naturc ofthese checks depends on the tlpe of dwice and themethod it uses to detect radiation or storp the information obtainedQuality contol samples of a variety of tlpes are used by the laboratory to veri$ the performanceof different portions of thc anatytcd prccess. These quality contnol samples include Uenks,replicatc samples, aoalytrcal knowns, blind samples, and sross-checks.BlaDks are samples which contain no measurable radioactivity or no activity of the t,"e beingmeasured. Such samples are analyzed to determine whether there is my contaminmion ofequipment or commercial laboratory chemicals, ctoss-contaminstion in the chemical plocess, orinterference from isotopes othcr than the one being measured.Duplicate samples are geireratcd atrandom by tbe sample comprrterprogram which schedulesthe collection of the routine samples. po1 sxsmple, if the routine progpm calls for fe6 milksrrnplels evetry lveek, on arandom basis each farm might provide an additional sample serreraltimes a year, Thcse duplicate samples are analyzed along with othcr routine mmples. Theyprovide information aboutthe vadability of radioactive content inthe various sample media If enough sample is available for aparticular analysis, the laborafory staffcan split it into trroportions. Such a sample provides information about the variability of the analytical prccesssince two identical portions ofmatedat are anallzed side by side.Analytical knowns are anothercategory of quality contol sample. A knolm amount ofradioactivity is added to a sample medium. The lab staffknows the radioactive content of thesample. Whenever possible, the analytical knoums contain the same amount of radioactivityeach time they are ruu. ln this way, analytcal knowns provide immdiate data on the quality ofthe measurcmelil prccess.Blind spikes are samples radioactivity which are intoduced into the aoalysisprocess disguised as ordinary environmental samples. The lab staffdoes not know thc sampleoontains radioactivity. Since the bulk of the ordinary workload of the environmelrtal laboratorycontains no measurable activity or only naturally occurring radioisotopes, blind spikes can beused to test the detection capabitity ofthe laboratory or can be used to test the dara reviewprcce$. If an analysis routinely ge,nerates numerous zeroes for aparticular isotope, the presenceof the isotope is brought to the atteirtion of the laboratory zuperrrisor in the daily review ptoc*ss.Blind spikes test this process since the blind spikes contain radioactivity at levels high enough tobe detected- Furthermore, the activity can be put into such samples at tk e:rte, e limit ofdctection (near the LLD) to veri$ tbat the labor*ory can detect very low levels of activity.Another category of quality conbol samples is th internal cross-ohecks. These samples have aknom amotmt of radioactivity addd and are presented to the lab stafflabeled as ctoss-checksamples. This means tbat the quality conEol staffknows the rddioactive content or tightanswed'but the lab petonnel performing the analysis do uot Such samples test the best -performance ofthe laboratory by determining ifthe lab can find the'tight answetr' Thesesamples provide information abort the accuracy of the measurcmentprocess. Flrthcrinformation is available about the variability of the prccess if multiple analyses are requested onthe same sample. Like blind spikes or analytical knonns, these samples can also be spiked withlow lcvels of activity to test dercction limia. The aoalysis results for intemal soss+hecksamples met program performance goals for 2013. To provide for an independent verification ofthe laboratory's ability to make acouratemeasurements, the laboratory participated in an e,nvironmental level cross-check plogramavailable through Ectert md Zegler Analytics during 2013. The results of fiA's participationin this cr'oss-check program are presentod in Table F-l. The results for thcse qoss-ohecksamples were all within the pogram agreement limits.The quatity contol data are routinely collecte4 exaqined and reported to laboratory supervisorypersonnel. They are checked for tends, problem aneias, or other indications that a portion of theanatytical proc*ss needs cotleqtion or implovement. The end result is a measuremcnt pmccss. tbat provides reliable and verifiablc data and is scnsitive eirough to measurc the presence ofradioactivity far below the levels which could be harmful to humans.-56: Tablc F-lBcsultfFgf ?013 Eldcrml Cross CtpcksTcst Pcri,odtrittlt QurrtcrFlrrt QurrlcrFilrt Qurrlcrtrftrt @rrterfm QurrErFftlt QurrlcrThhd aurrtrrThhd QorrtcrThlrd QurrtrThlrd QurrtcrThtrd QurrtrThlrd QuettrSamolc Typc l.tnalwisWaE(pCi/t)Cross B*taWaGr (pci/t)3Hw8E(pCi/L)rsrItlct,r.csItrcsttco"MnseFe65znocolllccSyutbcilic Urinc (pCi/L)rHMIk(pCi/L)BII'sr*srAir Filu (pCi/Fihff)Choss BcttWEEr(pcl/t).,HStd (pci/gram)t'crtrlcsl37G*co\,Intheo?.n'coAir Filffi (pCi/Filer)Crros BctEAir Filtr (IrCiffiltcr)ttcrt'cs,rcstcosMo5eFc6?.r,'coSymhaic Urirc (pCi/L)hMilk (pCi/L)r3rItst*srResultsKnown TVA3.00EjO2 2.5tE+021.40E+04 1.459+049.2t8+0I 9.528+014S28+i2 4.568+O22.058+02 2.0,,E+{22.54E+{2 2,56E<+21.998+02 2.0t8+02t.9.E+t2 2.l0BO22.4lB+s2 2.358i{lI22.88E+{2 3.128+023.t3E+02 3.ttE+02L79E+i2 l.t4E1O21.41E+Ot t.328+041.008+tD t.058+02t.908+0I 9.76E+0t9.828+00 1.058+018.468+01 8.208+019.968+03 1.068{{46.01E{r s.r?Eor3.738{1 3.39E{r2.r38{r Z70ESI2.33F.{lt 2"43E413.0tE{t 3.23E4t2.r3E{r 2.8tE{l5.nB4l 6.318{t4.24F.4t 4.4lE4t9.258+01 8.63E+012.228+{2 2.WE+{2t.388'10 l.l6E+021.05E+02 1.028+u8.63Et{l t.638{Oll.l lEj{r2 l. t4E+02t.058+02 1.058+02z.,3B+ry2 2.21E*ry2,1.578fi2 t.59E+02l.0lE+04 1.028+ot9.568+01 l.O0E+Olt.988+0t 1.008+m1.248+01 1.028+{lAgEW[YcsYesYesYesYesYesYesYcsYsYesYesYesYcsYesYesYesYesYesYesYesYcsYcsYesYesYcsYeYcsYesYesYcsYesYesYcsYesYesYesYesYcsYcs APPENDD(GLA}IDUSE SURVEY-58' Appendix GI"and Use.$-uryeyA tand usc suryey was conducted in accordancc with the govisions of ODCM Confiol 1.3.2 toidenti$ the location of the nearest milk nnimal, the nearest residence, and the neetst garden ofgreater tban 500 square feet producing fresh leafy vegetables in each of 16 meteorologicalsectors within a distance of 5 miles (8 km) from the plantThe land use survey was conducted between April l, 2013, and.October l, 2013, usingappropriate tecbniques such as door-todoor srrvey, meil suvsy, telephone survey, aerial survey,or informdion from local agricultrual authorities or other rcliable sources.Using the suwey data, relative radiation doses were projected for individuals
