Summary and Conclusions Thisport nthe Radiological Envir ental Monitoring Program conducted for the Dresden Nuclear Power Station (DNPS) by Exlon covers the peridd I January 2013 through 31 December 2013. uring that time period 2,023 analyses were performed on 1,885 samples. In assessing all the data gathered for this report it was concluded that the operation of DNPS had no advere radiological impact on the environment.

In 2013, the Dresden Generating Station released toithe environment through the radioactive effluent liquid and geseous pathways approximately 55 curies of fission and activation gases, 33 curies of Carbon-14 itid apprfietely 24 curies of tMitium. The dose from both, liquid and gaseous effiuents was conservatively calculated for the.Maximum Exposed Member.Qf the public. The results of those calculations and their comparison to the allowable timits were as follows:

1. Liquid Dose to a Member of the Public for 2013 Total Body: 1.22E-08 mrem which is 4.07E-07% of the 3 mrem/year limit.

Organ: 1.22E-08 mrem Which 1 .22E-07%'of the 10 mrem/year limit.

2. Gaseous Dose to a Member of the Public for 2013' '..

Total Body: 2.19E.02 mrem which is 2. IE-01% of the 10 mrad/ye limit.

Skin: 5.35E-03 mrnrm which is'2.68E-02% of the 20 mradlyear limit Organ (Pti"uAImodn*.):-. 9.22E-02 mrem .1SE-Ot% of the 15'°.-

mrem/yesr limit.

3. Direct Radiation Pose to a Member of the Public for '2013 Total Body: 8.76E+00 mrem which is 3.50E+01% of 40CFRI90 Limit of 25 mremlyear (Whole Body and Organ).

Thyroid dose: 2.30E-02 mrem which Is 3.07E-02% of 40CFRI90 Limit of 75 mrern/year limit.

The doses as a refaut of the radiological effluents released from the Dresden Generating Station were a very small percentage of the allowable limits, with the exception of 40CFRI90 whole body radiation which was calculated to be 35.0 %

of the 25 mrmnVyr limit. The largest component of 40CFRI90 dose is attributable to BWR skyshine from N-16. This value is co i calulated for the hypothetical maximum exposed member of the public.

Surface water samples were analyzed for concentrations of gross beta, tritium and gamma emitting nuclides. Ground water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No anthropogenic gamma emitting nuclides were detected. Gross beta and tritium activities detected were consistent with those detected in previous years.

Fish (commercially and recreationally important species), and sediment samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected in fish. Cesium-137 was detected In one sediment sample at a concentration consistent with levels observed In previous years. No power station produced fission or activation products were found in sediment.

Air partitouate samples were analyzed for concontations of 96a bet and gamma:emitting nuclides. Qrosw bete resui at the 1rdiccatof tloctons wer.

Optically Stimulated Luminescent Dosimetry were deployed and Thermolumindsbant Dosimetry (TLD) were dotinued. This change may result in a step change In readings, up or down, deperding on sits characterstc. The relatie comprisn to control locations rmnainvalid.

A. Objeotive of the Radiological Environment Monitonng Program REMP)

The objecMes of the REMP are to:

1. Provide data on measurable levels of radiation and radioactive materials in the sit environs.

2. Evaluat the relationship betmrn quantities of radioactive material released from the plant and resultant radiation.doses to individuals from principal psaths of exposure.

B. ImPlementtion of the Objece. -.-

The Implementn of the objectives is accomplished by:,

I. Identifying significanetexposure pathways.

2. Establishing baseline radiological data of media within those pathways. .

3, :Continuously monitoring those media before and during Station

.. :,-operation to assess Station radiologica effects (if any) on man and the environment...

Ill. Program Description A. Sample Collection Samples for the DNPS REMP were dollected for Exelon NuclearWb Environmental Incorporated Midwest Laboratory (EIML). This section describes the general collection methods used by EIML to obtain environmental samples for Vie DNPS REMP in 2013. Sample locations and descriptions can be found In Appendix B, Table B-1 and Figures B-1 and B-2. The collection methods used.bElML-re listed Ih8Table -2.

Agogai Envir~onmen . ,.qM' -...

The aquatic environment was fvaluated by perforihigradiological analyses on samples of surface-water (SV), ground WAter (GW), fish (FI) and sediment (SS). Samples were colled from three surfooe water locations (D-21, 0-52 and D-57) and cothposited for analysis. Control locations were D-52 and D-57. Samples were collected quarterly or more frequently from two well wate locations (0-23 and D-35)" -AN samples were collected in new unusedsplastic bottles, which were rinsed with source water prior to collection. Fish samples comprising the flesh of channel catfish, largemouth bass; common carp and freshwater drum were collected smiu at two locaut, D-28 and 046 (Contol).

Sediment samples composed of recently deposie substreib were collected at one location semiannually, 0-27.

Atmonohg nvtfoMeMnt °'::* ."..:.

The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate and airborne iodine (AP/AI).

Airborne iodine and particulate samples were colledm at fourteen locations (0-01, D-02, D-03, D-04, D-07, D408,,0-10, D-12; D-14, 0"45, D-63, D-55, D-56 and D-58). The control location was D-12. Airborne iodine and particulate samples were obtained at each location using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The air fltters and air iodine samples Were replaced weekly and sent to the laboratory for analysis.

Terrestrial Eimea t Milk (M) samples were collected biweekly at one control location (0-25) from May through October and monthly from November through April.

There are no Milking animals within 10 km (6.2 miles) of the site. All samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfite and shipped promptly to the laboratory. Food products (FL) were collected annually in September at five locations (D.Control, D-Quad 1, D-Quad 2, D-Quad 3 and O-Quad 4). The control location was D-Control. Various types of samples were collected and placed Innew unused plastic bags and sent to the laboratory for analysis.

AmIA Gama RlUggin *° Beginning In2012, ExeW changed the type of dosimetry used for the Radological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry (OSLD) were deployed and Thermoluminescent Dosimetry (TLD) were discontinued. This change may result in a step change in readings, up or down, depending on site charactefistics. The relative comparison to control locations remains valid. OSLO technology is different than that used in a TLD but has the same purpose (to measure direct radiation).

Each location consisted of two OSLO sets. The OSLD locations were placed on aind around the DNPS site as follows:

An inner doconsisting of 17 locations (D-58, 0-101, D-102, D-103, D-104, D-105, -106, 0-107, D-106, 0-109, D-110,0D-111, D-112a, D-113, D-114, 0-115 and D-118) atornearthesite boundary.

An gWK djg-oonsistin of 16 locationis (D-201,0D-202;,0-203,0D-204, D-205, D-20W, D-207, D-206,'0.209, 0-210,0-211,0-212,0-213, D-214, 0-21 5 anid D-216) approkdmately 5 to .10 km (3.1 to 6.2,miles) from the site.

Qft consisting of OSLO sets at tOe 13 -air sampler locations (D-01, D-02, D003, D-04,0-07, D-08, 0-1, 0),14,0--45, D-53,.D-55, 0-56 and 0-58).

The balance of one location (D-12) represents the control area!OSLD set.

The OSLOs were exchangod quarerly and sent to Lnda.er for analysi.

B Sample Analysis This section describes the general analytical metwodologimused by TBE and EIML to analyze the environmental samples for radioactivity for the DNPS REMP in 2013. The analytical procedures used by-the laboratories are listed in Appendix B Table B-2, In order to achieve the stated objectives the current program includes the following analyses:

1. Concentrations of beta emitters In surface water and air particldates.

2. Concentrationsof gamma emitters in ground and surface water, air particulates, milk fh,fsedlment and vegetation.

3. Concentratonsof Mtium in ground and surfae water..

4. Concentration*of t31 in air and milk.

5. Ambient gammaradiation levls at vrious, fte environs.-

C. Data Interpreta..o, For the purpose of this report, Dresden Nuclear Power Station was considered operational at initial criticality. In addition, data were cpared to prsvki yars' opational data for consistency and trnding:..Several factors were Impotant in the interpeto of the data:

The lower limit of detection (LLD) wm defined as the smallest concentration of radioactive material in a sample that would yield a net count (above backgound) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "rear' signal. The LLD was Intended as a before the fact estimate of a system (incklding instrumentation, procedure and sample type) and not as an after the fact criteria for the presence of activity. All analyses were designed to achieve the required DNPS detection capsbiti for environmental sample analysis.

The minimum detectable concentration (MDC) is calculated the same as the LLD with the exception that the measurement is an after the fac estimate of the presnce of activity.

2. Net A*tv't Calculation and ReBoMrina of Results Net activity for a sample was calculated by subtractirg background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations may result in sample activity being lower than the background activity effecting a negative number. An MDC was reported in all Cases where positive activity was not detected.

Gamma spectoscopy results for each type of sample were grouped as follows:

For groundwater, surface water, and vegetation twelve nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn45, Nb-95, Zr.95, 1.131, C9-134, Cs-137, Ba-140 and La-140 won reported.

For fish, sediment, air particulate end milk elevern nuc~ides;,

Mn-54, Co-58, Fe-59, Co-60, Zn45, NW-95, Zr-95, Cs-134, CA-137, Ba-140 and La-140 were re .: ,,.

Means and standard deviations of the result were" calculated. The standard deviations represent the varIabi of measured results for different samples rather than single analysis uncertainty.,

D. Program Exceptions For 2013 the DNPS REMP had a sample recovery rate greater than 99%.

Sample anomalies and missed samples are isted in the tables below.

1. Surface Watero'w Samples were composited or taken weekly and cmposi*td for analysis at three locations (D-21, D-52 and D-57). Of these locations only 0-21, located downmstra, could be affected by Dresden's effluent rmlas. The win analyses w*ar performed:

Monthly composites from all locations were analyzed for concentonsof gross beta (Table 0-4.1, Appendix C). Gross Beta was detected in afllsamples. The values ranged from 3.2 to 26.2 p0CUA. -Concenbutions deMtcted were consistent with those detected In previous years (Figures C-I, C-2 end C-34 Appendix C).

TAUm Quarterly composite from all locations were analyzed for tritium activity (Tiabl. -l.2, Appendix C). "Three samples at indicator tation D.21 were positie for tritium. The values ranged from 475 to 687 pCi/L. Four samples at control station D-57 were positive for tritium. The values ranged from 618 to 6550 pCilL. Concentrations detected were consistent with those detected in previous years (Figures C-4, C-5 and C-6, Appendix C).

B. Atmospheric Environment I. Arbome

a. Air Particulates Continuous air particulate samples were colaecod from fou -elocationson a wely basis. The fouteen locations wete spat Ito four grups: O-t.sbsamplers (D601, D.

02 and D-03), Near-eld 6a lrs witMh 3.1 miles of the sie (D-04, DO7, D"45; 0-53, D-66 and 0-58), Far.4ield samplers between 5 and 10 km (3.1 and 6.2 miles) from the site (D-08, 0-10, D-14 and 0-55) and the Control sampler between 10 and 30 km (6.2 and 18.8 miles) from the site (0-12). The followhn analyses were perfiormd:

Weekly samples were analyzed for concentra',ios of beta emtes (Tabe C-V.1 and C-V.2, Appendix C)..

Detectable gross beta activity was observed at all locations.

Comparison of results among the four groups aid in determining the effects, If any, resulting from the operation of DNPS. The results from the On-Site locations ranted from 7 to 57 E-3 pCi/m3 with a mean of 20 E-3 pCi/mi. The results from theNear-Field locations ranrd from 5 to 54 E-3 pCi/m 3 with a mean of 20 E-3 pCi/m . The results from the Far-Field locations ranged from 8 to 63 E-3 pCI/m 3 with a mean of 21 E-3 pCi/M3 . The resufts from the Control location ranged from 5 to 52 E-3 pCi/m 3 with a mean of 21 E-3 pCi/m 3 . Comparison of the 2013 air particulate data with previous years data indicate no effects from the operation of DNPS. In addition a comparison of the weely, mean values for 2013 indicate no notable differences among the four groups (Figures C-8 through C-14, Appendix C).

Ga1mmagwoefotbl Samples were comp**W quartry and analyzed for gamma emitting nuclides (Table C-V.3, Appendix C).

Naturally occurring We-7 due to cosmic.ray activity was detected in 53 of @4 samples and ranged from 37..5 to. 110 E-3 pCi/M3. Naturally occurring K-4-0 was detected in one of 54 samples at a concentration of 24.7 E-3 pCi/rn3. No anthropogenic nuclides were detected and all required LLDs were met. These samples were consistent with historical quarterly results. Al other nudides were less than the MDC.

b. Airborne Iodine Continuous air samples ware collected from fowteen locations (D-01, 0-02, 0-03, 0.04, D-07, D-08, 0-10, D-12,

.- 14, D-45, 0-53, 0-55, D-568 and -68)and analyzed

-. weekly for 1-131 (Table C-VI.1, ppendix C). All results

--.*... wmlesa e than the MDC forl1-131,.-.

2. Terresial.I

a. Milk There are no Indicator locations within 10 kilometers of the station. Samples were collected from one control location (0-25) biweekly May through October and monthly November through April. ,The following analyses were performed:

Milk samples from the location were analyzed for concentrations of 1-131 (Table C--VLI., Appendix C). No 1-131 was detected and all required LIDs were met.

Each milk sample was analyzed for concentrations of gamma emitting nuclides (Table C-V1I.2, Appendix C).

Naturally occurring K-40?0ctivity was found in all samples.

No other nuclides were deftote1 and a09 required LLDs were

,met. L- ..

b. Food Products .

Food product samples were collected at five locations (D-Contol, 1-Quad 1, 0-Quad 2, D-Qua4d3 and D-Quad 4) wihen available. Four locations, (O.Quad 1, -Quid 2',.....

0-Quad 3 and D-Quad 4) could be affected by Dresden's effluent releases. The following analysis was performed:

Samples from aN locaions were analyzed for gamma emitting nuclidi (Table C-MIl.I, Appendix C). No nuclides were detected and all required LLDs were met.

C. Ambient Gamma Radiatio Beginning in 2012, Exolon changed the type of dosimetry used for the Radiological Enviro1m Monitoring Program (REMP). Optically Stimulated Luminescent Dositmey (OSLD) were deployed and Thermolunnewent Doswimy (TLD) were discontinued. This change may result in a stop change in readings, up or down, depending on site characteistics. The relative companson to control locations remains valid. OSLD technology is different than that used In a TLD but has the same purpose (to measure direct radiation). Forty-six OSLD locations wer established around the site. Results of OSLO measurements are listed in Tables C-IX.I to C-IX.3, Appendix C.

MostOSLD meauement wre below 30 mR/quarter, with a range of 22.6 to 38.7 mRlquarter. A comparison of the Inner Ring, Outer Ring and Other locations' data to the Control Location data, Indicate that the ambient gamma radiation levels from the Control location (D-1 2-01and D-12-02) were comparable.

D. Land Use Survey A Land Use Survey conducted on August 28, 2013 around the Dresden Nuclear Power Station (DNPS) was performed by EIML for Exelon Nuclear to comply with Section 12.6.2 of the Dresden Offiste Dose Calculation Manuat (ODCM). The purpose of the survey was to document the nearest resident or industrial facility, milk producing an"in , and livestock in each of the sixteen 22 % degree sectors within 10 km (6.2 miles) around the site. There were no changes required At the DNPS REMP as a result of this survey. The results ,thi survey are summarized below.

For the gamma system, when the new detector number 08 was added to the system in January 2012, the default value of 3.29 was uLWtoca.ltculated the'MDCs on detector 08. The activity!and unceftnty were not 'affected. The multiplier has been Chg from 3.29 the required 4.66.

When the MDCs are recalculated using 4.66,. the MDC values will Increase by 41.6%. The greatest impact will be on the short-,ived nuclides which have an LLD requirement, e.g. 1-131, Ba-140 and La-140. Which means there could be some missed LLDs which will be Identified in the Errata Data Appendix table of the 2013 annual report. This is not a reportable Issue for the NRC. There isalso the possibility that naturally produced nuclides that wre detectod would become a n4 c, e.g, Th-228, Th-230, etc.

F. Summary of Results - IntMr'bordary. Campafson Program The primary laboratory analyzed Evaluation (PE) samples of air padrule, O'r iodine, milk,sodil, vegetaon and watWe matrices (Appendix 0). The PE sampl,,supplie b Analytics Inc., Envirnmental Resource Associ (ERA) and DOE's d An*lyt Pef Evaluation Program (MAPEP), were evaluatedigainst the followi pre.

Analy' evaluation-rea provides a ratio of lborory results and AnalyW' known value. Sinos flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on Intemral OC requirements, which are based on the DOE MAPEP criteria.

2. ERA, Evaluation Criteria ERA's evaluation report provides an acceptance range for cntrol and wa*!rng lims with issocieW flag values. ERA's abceptance limits are established per the USEPA, NELAC, state specific PT

-.16-

program requirements or ERA's SOP for the Generation of PeormAnce Acptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or-a fixed percentage limit promulgated under the appropriate r~gator document.

3. DOE Evaluation Cr1tea48 MAPEP's evalu*a*inreport provides an , .ceptane,ranewth associated fn values.

The MAPEP defines three levels,Of performaonce; Apaeptabe (Nag = "A'), Acceptable with Warn (flag.= ) and NWt Acceptable (flag = 14-). Performance is considered acceptable when a mean result for the specified arialyte is

If the bras is.grater than 30%, the For the TOE laboratory, 178 out of 185 analyses performed met the specified acceptance criteria. Seven analyses (Sr-89 and Sr-90 in milk, Co-S?, Zh-85 ohd:S90 in soil, Cs-1 34 in air particulate and Sr-90 in vegtat~n two ta*warning ina rowJ) did not meet the spSedW accptacecriteria, or Infternal Q eurmnsfor the fOoll"M reason:

1. Troyne Brown En's Analytics Sepmber 2013 Sr-89 in milk rsu of 63.9 pCi/L was lower than the knwmn vakuof 96.0 pCU/L. The failure was a result of analyst error and was specific to the Analytics sample. Client samples for the associated time period ware evaluated and no client samples ware affected by this failure. NCR 13-15

2. Teledyne Brown Engineerng's Analytics September 2013 Sr-S0 in milk result of 8.88 pCi/L was lower than the known value of 13.2 pCi/L. The failure was a result of analyst error and was specific to the Analytic sample. Client samples for the associated time period were evaluated and no client samples were affected by this failure. NCR 13-15

3. & 4. Teledyne Brown Engineering's MAPEP September 2013 Co-57 and Zn.O5 in soil were evaluated as falling the false positive test.

While MAPEP evaluated the results as failures, the gamma software listed the results as non identified nuclides. The two nuclides would never have been reported as detected nuclides to a client. MAPEP does not allow laboratories to put in qualifiers for the submitted data nor "less than" results. MAPEP evaluates results based on the relationship between the activity and the uncertainty. MAPEP spiked the soil sample with an extremely large concentration of Eu-152, which was identified by the gamma software as an Interfering nuclide, resulting in fgrr. activity results that were evaluated by MAPEP as detected Co-57 and Zn-65. No client samples were affected by these failures. NCR 13.14

5. Teledyne Brown Engineering's MAPEP September 2013 Sr-90 In soil result ofe64 Sq/kg was higher than the known value of 460 Sq/kg, exceeding the upper control limit of 598 Sq/kg. An inconrect Sr-90 result was entered Into the MAPEP database. The correct Sr-90 activity of 322 Bq/kg would have been evaluated as acceptable with warning. No client samples were affected by this failure. NCR 13-14

6. Teledyne Brown Engineering's MAPEP September 2013 Cs-134 in air particulate activity of -0.570 Sq/sample was evaluated as a failed false positive tet, based on MAPEP's evaluation of the result as a significant negative value at 3 standard deviations. A negative number would never have been reported as a detected nuclide to a client, therefore no client samples were affected by this failure.

NCR 13-14

7. Teledyne Brown *flgel', MAPEP September 2013 Sr-90 In vegetation result was dvt lue to two low warnings In a row. It appears the September sample was double spiked with carrier, resulting in a low activity. With a recovery of around 50%

lower, the Sr-90 result would have fallen within the acceptance range. No client samples ware affected by this issue. NCR 13-14 APPENDIX A RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT

APPENDIX E ERRATA DATA

iftnftlohlyleft blan

Due to an Incorrect setting on gamma detector 0C, 3.29 rather tna 4.66 was used in fte MDC calculatIon. Nonconfomisnoe 13-07 was initiated and corrective actions have been implemftd to address this issue. AN samples counted on detector 08 were repwoessed using the correct calculation. As a result, all MDCs for these samples have Increased by 41.6%. The previously reported activities and uncertaintles were not affected. In some cames, the increased MDC resulted in missed LL. All samples with MDC* affected by this Issue are listed below. The samples with missed LLDs are shown in the tble for 2011, 2012, and 2013. All other required LLDs wre met.

L.Suiwny andCoceln Dresden Station is situated on approximately 600 acres of lanW that borders the Illinois River to the north and the Kankakes River to the east. This land Is referred to as the owner-controlled area. The Dresden power plant itself takes up a small parcel of the owner-controled area and Is surrounded by a Security fence. The security fence defines what is known as the ProtectedAAre (PA).

The Dresden power plant has experienced leaks from underground lines and spills from systems containing radioactive water over its 50 yew history. These iwfntshave created a number of areas of localized contamination within the PA. The liquid .

scintillation analyses of groundwater in many of these areas show measuable cocentrons of tritium (H-3).

Dresden participated in a flsetwide hydrogeologic iainduring te-summer of 2006 in an effort to charactei gundwar movement at each site. This-Invstigon also compiled a list ofhe histric spilsand leaks as well as a detailed analysis on groundwar hydrology for Dresden Nuce Genertion Station. ComiiMg the brtur concentration In a locally conteminated arms with the speed. and rection of groundwater in the vicinity can produce a contaminated, grounrw!1 plums projection. If the plume of contaminated gmundwater passes through the path of.a groundwater motring well, it can be anticipated that the tritiumconcenratin .th hi weft will increase to some maximum concentration, then decrease over time.

The fleetwide Hydrogeologc In on Report (HiR) shows that goundwater movement on the Dresden site is wery slow. In addition, ther is a confing rock layer, the Maquoketa Shale layer, about 55 feet below the surface that impedes oundwater movement below this depth.

Dresden has a domestic water system that is supplied by two deep wells (1500 feet deep) that were installed about 50 years ago south of the PA. Samples taken from domestic water supply have never shown any detectable tritum carcentration.

Tritium has a halflife of 12.3 years. This means that 40yare from now 90% of the tritium on site today will havedecayed away to more stable elements. Given the limited volume of contaminated groundwater on site, radloacive decay, slow groundwater movement and dilution efffcts, the-condulsion of the HIR is-that the operation of Dresden Nuclear Power Station has no adversoradiological impact on the environment As a result there is little potential for contaminated groundwater on site to affect off-site drinking water.

111.- ktroduction Radloloaicat Groundwater Monltor9t ProaMm MRee):

Dresden has a Radiological Groundwater Monitoring Program (RGPP) that provides long-term monitoring intended to verify the fleet-wide hydrogeologic study conclusions.

Dresden uses deweoped groundwater wells and surface water sample points In the RGPP."

The Dresden RGPPws=established in 200 and them hae been no significant changes to-this program. This program does not impact theopeation of the plant and is independent of the REMP.- . '

Developed groundwate wells areelthat r were Insalled specifically for monitoring groundwater. These wells are equipped with screens and are properly sealed near the surface to avoid surface water Intrusion. The wells were designed in accordance with appropriate codes and developed in accordance with appropriate standards and procedures. Dresden has;groudwaellr monioring wellsidentifiKd as "shallow" (depths from 15 to 35 et),-nmedftW (depths from 35 -to55 fet) and "deep" (depths beyond 100 feet).,-.All wells installed to a depth greater then 100 feet ("deep" wells) were found to be dry and removed from the RGPP. Surface water sample points are ident sample-locatins In the station's canals and cooling pond.

There are 98 sampling poinitin the RGPP:

Dresden has 47 deIloped groundwater monitoing ellst within the Proed Ares (PA). Somewf thesewes form a ring just inside the security fence and the remaining wellswere installed rna underground plant system piping that contains, radioactive waer.

Dresden has 30 developed groundwater monitoring wells outside the PA the majority of which form a ring just within te perimeter of the property.

Dresden has 11 surface water monitorng locations on the owner-conVolled area sampled as part of theDresden RGPP.

Dresden Me 4.precipitation peter monitoring locations sampled as part of the Dresden RGPP.:.Anadditional 8 locations were studied in 2011 through 2012, but only 4 locations are currently permarnetly, a part of the RGPP program.

Dresden has,6,sentinel wells..' These-wells are not constructured to code or developed to a standard. The majority of these wells are idle and only used for qualitativetroubleshooting. - ,

"2-

The Dresden stespwfi RGPP procedure Identifies the historic 'event that would affect the individual RGPP sample results. This procedure identifies threshold values for each sample point, which If exceeded, could be an indication of a new spill from an above ground system or a new leak in an underground pipe containing tritiated water.

The RGPP sample points are currently sampled on a frequency determined by the well detection category in accordance with site document EN-DR-408-4160, Dresden RGPP Reference Material. During 2013, there were 578 analyses that were performed on 251 samples from 74 sampling points.

Sentinel Wells, sometimes referred to as "baby wells are wells that were installed to monitor local shallow groundwater; typically in associated with a historic underground pipe leak. These wells are not constructed to code or developed toe.,tandard, Most sentinel wells are from 6 to 12 feet deep and consist of 2" PVC pipe without screens.

These wells are categorized as idle wells and are used only for troubleshooting purposes.

Dresden has tw basic storm water runoff sewer systems within the PA: one storm-system routes to the east, then north and discharges into the Unit I intake canal, the second storm-system routes to the west, then north, through a large Oil/Water Separator and discharges to the hot canal. Both the Unit I intake canal and the hot canal eventually route to the cooling pond. The Dresden Station RGPP has eight RGPP surface water sampling points to monitor these sysms.

A. Objectives of the RGPP ..

The Objective of the RGPP is to provide long-term monitoring intended to verify the fleet-wide hydrogeologic study conclusions. The objective of the site-specifi RGPP is to provide indication of shot-term changes to groundwater trtium con tations within the PA.

If isotopic results of groundwater samples exceed the thresholds specified in this procedure it could be an indication of a new spill from an above ground system or a new leak in an underground pipe containing Vitiated water. -

Specific Objectives include:

1. Perform routine water sampling and radiological analysis of watW from selected locations.

2. Report new leaks, spills, or other detections with potential radiological significance to stakeholders in a timely manner.

3. Regularly assess analytical results to identify adverse trends.

D. Charctrmstics of-.Tritium (H.-3)

Tritium (chemical symbol-H-3) is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called "tVitiated water." The chemical properties of tritMum am esmmetilly those of ordinary hydrogen.

Tritiated water behaves the same as ordinary water in both the environment and the body. Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through skin. Once tritium enters the body, it dsperse quickly and Isuniformly distributed throughout the body. Tritium is excreted primarily through urine with a clearance rate characti zed by an effective biological half-life of about 14 days. Within one month or so after ingestion, essentially all tritium Is cleared. Organically bound tritium (tritlum that Is incorporated in organic compounds) can remain in the body.for a longer period.

Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium isalso protuced during nudles( wmpons explosions, as a by-product inreactors producing electricity and Inspecial production reactors, where the isotopes lithium-7 and/or boron-lO are activated to produce tritium.

Like normal water, tritiated water Is colorless and odorless. Tritlated water behaves chemically and physically like non-tritlated water in the subsurface and therefore tritiated water will travel at the same velocity as the average groundwater velocity.

Tritium has a half-lif of approdmately 12.3 years It decayspottamoousiy to hellum-3 (31H.). This radioactive decay rolee a beta pulft (low1n1rgy electron). The radioactive decay of tritium Is the wota of the heMlth risk from exposure to tritium. Tritium emit very weak radiatio Od leavethe body ' -

relatively quickly. Since tritium is almost always found as water itgoes directly into soft tissues and orgns. The associated dose to them tissues Is gonerally uniform and is dependent on the water conrte of the specfi tissue.

UL Progrm DesPUion A. Sample Analysis This section describes the general analytical metoologies Wued by Teledyne Brown Engineers (TBE) to analyge the environmental samplfs for radioe*t1ty for the Dresden Nuclear Power Station RGPP in 2013.

In order to achieve the stated objectives, the cuttfet program includes the following analyses: : * - ...-.. ,, "

1. Concentrations of gamma emitters in grotndwOs. and surface water.

2. Concentrations of strontium in groundwater.

3. Concentrations of tritlum in groundwater, surface water and precipitation weter..

4. Concentrt0ons of gross alpha and gross beta Ingroundwater.

5. Concentrations of Am-241 in groundwater.

6. Concntmaons of Cm-242 and Cm-243/244 in groundwater.

9. Concentrations of Fe-55 in groundwater.

10. Concentrations of N1.63 in grudwatr.

B. Data Interdfaion Ills radiogical data collected prior to Dresden Nuclea Power Station becoming operational wet9 used as a basel with which thes operaionl~date were compared. For the purpose of this report, Dresden Nuclear Power Station was cseredoperationalt initialcrtclity. Severa factors waee I ttnImtn t the interptation of the data:-

1. -LK M iQM an t~nimUMu The Lower Umit of Detection (LLD) is the minimum sensitity value that must be achieved routinely by the analytical parameter.

2. LIT The estimated uncertainty in measurement of titlum in environmental samples is frequently on the order of 50% of the meaurement value.

Statistically, the exact value of a measurement is expressed as a.

range with a stated level of confidence. The convention is,to.report results,with.a 95% level of confidence. The uncertainty comes from calibration standards, sample volume or weight measurements, sampling uncertainty and other factors. Exelon..

reports the uncertainty of a measurement created by statistical process (counting error) as well as all sources of error (Total Propagated Uncertainty or TPU). Each result has two values calculated. Exelon reports the TPU by following the result with plus or minus t the estimated ample standard deviation as TPU that is obtained by propagati all sources of analytical uncertainty In measuremnents.

Analytical unceitainties ar reported at the 96% confidence level in this report for reporting consistency.with the AREOR;.

The purpose of the following discumlon is to summarize.

bacgrod meurmesof tritum:in various media performed by otwS. Addiol detal mn"be fou by ecnultn referenoce (CRA 2006)..:* "

a. Tritium Production processes both cmic and suberranMean, as well as from anthropogenic (i.e., man-tmad), ourmes. In the upper atmohere *Cosmogenlc tritium Isproduced from fth bomb ent of stable nucies and combines with oxygen to form tritlated water, which wilt then enter the hydrologic cycle. Below ground, lithogenlcW tritium is produced by the bmArdmntof natural lithium present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant uranium and thorium. Lithogenic production of tritium Is usually negligible compared to other sources due to the limited abundance of lithium In rock. The lithogenic tMtum is introduced directly to groundwater.

A major anthropogenic source of Mritium and strontium-O comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium In precipitation increased lnfficantly durng Me 1960.sn early .196s,and, er with additional testing, resulting in the release of significant amounts of tritium to the almosphere. The Canadian heavy water nuclear power reactors, other commercial poWer reactors, nuclear research, and weapons production continue to influence tritium concentrations In the environment.

b. Precipitation Data PreAIpitatUon samples are routinely collected at stations around the world for te analysis of tWum and other radionuclides. Two publicly available databases that provide tritium concentraiorns in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet detabase. GNIP provides tritium precipitation concentration data for samples collected woldwide from 1960 to 2006.

RadNet provides tritium precipitation concntratio ditaf6X &

samples collected at stations throughout the U.S. from 1960 up to and including 2006. Based on GNIP data for sample

°* stations located In the U.S. Midwest, tritium concentrations peaked around 1963. This peak, which approached 10,000 pCi/L for some stations, coincided with the atmospheric -

test"in of thermonuclear weapons.

Tritium concentrations In surface water showed a'sharp decline up uhtil 1975 followed by a gradual decline since that time. Thitium-concentrations in Midwest precipitation have typically- ben below 100 pCi/L since around 1986.

Tritiumconcentrtions in wells may still be above the 20W' pCilL detection limit from the external causes described

.8-

majority were installed in areas of historic spills or close to piping containing tritiated water (Table 8-1. 1, Appendix B).

IMDI&m Samples were collected and analyzed for strontlum-89 and strontium-G0 activity (Table B-1.1, Appendix B). Stronthun-89 was not detected in any of the samples. Strontium was detected at a concentration greater than I pCi/L at two sampling locations (DSP-108 and MW-DN-105-S). The concentrations ranged from 1.5 to 4.9 pCi/L. C. .1i .

Gross Aloha gnd Gros §Mt Wdisove MAn Suonded)

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples throughout the sampling year In 2013. Gross Alpha (dissolved) was detected in ten groundwater locations. The concentrations ranged from 1.3 to 15.6 pCi/L.

Gross Alpha (suspended) was detected in one groundwater location at a concentration of 1.0 pCi/L. Gross Beta (dissolved) was detected In 32 of the groundwater locations. The concentrations ranged from 2.7 to 46.8 pCi/L. Gross Beta (suspended) was detected in one groundwater location at a concentration of 30.2 pCUL. The conoentrations of Gross Alpha and Gross Beta, which are slightly above detecable levels, are considered to be background and are not the result of plant effluents.

Gammna EmM Naturallyocc(ung K-40 was detected in two samples. The concentrations ranged from 37 to 65 pCi/L. No other gamma emitting nuclides were detected (Table 8.4.2, Appendix 0).

Hard-To-Detect analyses were performed on two groundwater locations to establish background levels. The analyses included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-2391240, U-233/234, U-235 and U-238. The isotope U-233/234 and U-238 was detected at one of the two groundwater monitoring locations. The concentration of U-234 was 1.0 pCi/L and the concentration U-238 was 0.39 pCi/L (Table B-1.3, Appendix B). The concentrations detected are considered background.

All other hard-to-detect nuclides ware not at oentrations greater than their rspective MDCs. ..

above. Water from previous years and decades is naturally captured in groundwater, so some well water sources today are affected by the surface water from the 1960s that was elevated Intritium.
