Most ofthese analyses were performed to satisfy the requirements of the Offsite Dose Calculation Manual (ODCM) (Ref. 6), the Environmental Technical Specifications (Ref. 5) and theIndependent Spent Fuel Storage Installation (ISFSI) Technical Specifications (Ref. 10). Some ofthese samples, although not required by either the ODCM or the Technical Specifications, werecollected to maintain our commitments to the surrounding community and to maintain historical continuity of the CCNPP Radiological Environmental Monitoring Program (REMP) that startedin 1970. The entire monitoring program in place around CCNPP is divided into three parts: theoriginal REMP, the ISFSI monitoring

program, and the Non-ODCM Radiological Environmental Monitoring.

The following paragraphs describe each of these parts in more detail.A total of 651 radiochemical analyses were performed on 583 environmental samples and 546thermoluminescent dosimeters (TLDs) were analyzed for ambient radiation exposure rates aspart of the original REMP. These analyses were performed to satisfy the requirements of theODCM (Ref. 6) and the Environmental Technical Specifications (Ref. 5).For the ISFSI monitoring

program, 360 radiochemical analyses were performed on 300environmental

samples, 64 of which were in common with the original REMP. In addition, 480TLDs, 24 in common with the original REMP, were analyzed for ambient radiation exposurerates. These analyses were performed to satisfy the requirements of the ODCM (Ref. 6) and theISFSI Technical Specifications (Ref. 10).In addition, 675 analyses were performed on 586 additional environmental

samples, and 480additional TLDs were analyzed for ambient radiation exposure rates.And lastly, 232 radiochemical analyses were performed on 232 quality assurance samples and126 quality assurance TLDs were analyzed as part of an internal and external quality assurance program associated with Teledyne Brown Engineering.

Laboratory intercomparison samplesobtained from Environmental Resource Associates (ERA) and Analytics' Inc. were alsoanalyzed.

Samples collected from the aquatic environment included bay water, fish, oysters, and shoreline sediment.

Bay water was analyzed for tritium and gamma emitters.

Fish, oysters, and shoreline sediments were analyzed for gamma emitting radionuclides.

Monitoring the atmospheric environment involved sampling the air at various locations surrounding CCNPP and the ISFSI. Air particulates and gaseous iodine were collected on glassfiber filters and charcoal cartridges, respectively.

The particulate filters were analyzed for betaactivity and gamma emitting nuclides.

The charcoal cartridges were analyzed for airbornegaseous radioiodine.

I January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 Samples from the terrestrial environment consisted of vegetation and soil samples collected andanalyzed for gamma emitters.

Vegetation samples for the original REMP were also analyzed for1-131.Measurements of direct radiation, as required by the ODCM, were performed by analyzing TLDsfrom forty locations surrounding CCNPP and the ISFSI.Natural radioactivity was detected in essentially all 3468 radiological analyses performed.

Lowlevels of man-made fission products were also observed in 17 of these analyses for the CCNPPREMP. Sixteen of these observations were attributed to fallout from past atmospheric weaponstesting while one analyses yielded low level positive results for the presence of H-3, which isattributable to plant operation.

Detailed discussions about the results of these analyses arecontained in the body of this report.To assess the plant's contribution to the radiation levels of the ambient environment, dosecalculations were performed using the plant's effluent release data, on-site meteorological data,and appropriate pathways.

The results of these dose calculations indicate:

a. a maximum thyroid dose of 1.56 x 10-2 mrem via liquid and gaseous pathways, which is about 0.02 1% of the acceptable limit of 75 mrem/yr as specified in40CFR190 "Environmental Radiation Protection Standards for Nuclear PowerOperations" and 1 OCFR72.104, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste";b. a maximum whole body gamma dose of 1.17 x 10-3 mrem via liquid and gaseouspathways, which is about 0.005% of the acceptable limit of 25 mrem/yr asspecified in both 40CFR190 and 1OCFR72.104; andc. a maximum calculated dose to all other organs via liquid and gaseous pathwayswas equal to 1.64 x 10-3 mrem to the skin. This dose is about 0.007% of theallowable limit of 25 mrem/yr as specified in both 40CFR190 and 1OCFR72.104.

Thus, it is concluded, based upon the levels of radioactivity observed and the various dosecalculations performed, that CCNPP Units 1 and 2 and the ISFSI did not cause any significant radiological impact on the surrounding environment.

2 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 II. CALVERT CLIFFS NUCLEAR POWER PLANTRADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAMII.A. INTRODUCTION Constellation Energy Nuclear Generation (CENG), previously known as Baltimore Gas andElectric Company (BGE), has been conducting a REMP in the environs of the CCNPP since thesummer of 1970. The Calvert Cliffs site is an operating nuclear generating station consisting oftwo pressurized water reactors.

Unit 1 achieved criticality on October 7, 1974 and commenced commercial operation in May 1975. Unit 2 achieved criticality on November 30, 1976 and wentinto commercial operation April 1, 1977. The location of the plant in relation to localmetropolitan areas is shown on Figure A-1.Results of the monitoring program for the pre-operational period have been reported in a seriesof documents (Ref. 1-4). The results from previous operational periods are contained in annualreports submitted to the Nuclear Regulatory Commission (NRC) as required.

Results of the monitoring program for the current operational period are included in this report.The report presents the content of the REMP (Table 1), the sampling locations (Appendix A), thesummary of the analytical results (Table 2), a compilation of the analytical data (Appendix B),the results of the Interlaboratory Comparison Program and the Quality Assurance Program(Appendix C), the results of the Land Use Survey (Appendix D), a compilation of the analytical data for extra samples collected (Appendix E), and Errata for the 2011 AREOR (Appendix F).Interpretation of the data and conclusions are presented in the body of the report.The environmental surveillance data collected during this reporting period were compared withthat generated in previous periods whenever possible to evaluate the environmental radiological impact of CCNPP Units 1 and 2.ll.B. PROGRAMII.B.1 Objectives The objectives of the REMP for the Calvert Cliffs Nuclear Power Plant are:a. To verify that radioactivity and ambient radiation levels attributable to plantoperation are within the limits specified in the ODCM (Ref. 6) and theEnvironmental Radiation Protection Standards as stated in 40CFRI90,

b. To detect any measurable buildup of long-lived radionuclides in the environment,

c. To monitor and evaluate ambient radiation levels, andd. To determine whether any statistically significant increase occurs in theconcentration of radionuclides in important pathways.

3 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 II.B.2 Sample Collection The locations of the individual sampling stations are listed in Table A-i and shown in Figures A-2 and A-3. All samples were collected by contractors to, or personnel of Constellation EnergyNuclear Group according to CCNPP Procedures (Ref. 7, 8 and 12).II.B.3 Data Interpretation Many results in environmental monitoring occur at or below the minimum detectable activity(MDA). In this report, all results at or below the relevant MDA are reported as being "less than"the MDA value.II.B.4 Pro2ram Exceptions There was a loss of data for a weekly air sample collected from an ODCM (Ref. 6) samplinglocation during this operating period. The iodine cartridge and particulate filter at theEmergency Offsite Facility (sample code A5) for the week ending 02/11/2013 was mistakenly redeployed at another location for a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. New air sample filters were replaced toprevent further loss of data. The filters for A5 were analyzed and found to be within normalranges however the data was rejected since it was a mishandled sample. This program exception was entered into the site's Corrective Action Program.One direct radiation dosimeter, in 1st quarter was found missing from an ODCM (Ref. 6)sampling location during this operating period. A direct radiation dosimeter was not taken fromthe Route 765, Auto Dump sampling location (sample code DR02) in the 1st quarter of thisoperating period. No substitute sample was collected in lieu of the sample not taken from thislocation.

A direct radiation dosimeter was replaced at this location for the purposes ofmonitoring direct radiation per the ODCM (Ref. 6), and this program exception was entered intothe site's Corrective Action Program.II.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using Constellation Energy laboratory procedures (Ref. 8). The analytical results for this reporting period arepresented in Appendix B and are also summarized in Table 2. For discussion, the analytical results are divided into four categories.

The categories are the Aquatic Environment, theAtmospheric Environment, the Terrestrial Environment, and Direct Radiation.

These categories are further divided into subcategories according to sample type (e.g., Bay Water, AquaticOrganisms, etc., for the Aquatic Environment).

II.C.1 Aquatic Environment The aquatic environment surrounding the plant was monitored by analyzing samples of baywater, aquatic organisms, and shoreline sediment.

These samples were obtained from varioussampling locations on the Chesapeake Bay near the plant.4 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 H.C.l.a Bay WaterMonthly bay water samples were taken from two locations during the year. These locations arethe Intake Area (sample code WAI) and the Discharge Area (sample code WA2). Composite samples were obtained from each location for the entire sampling period. These samples wereanalyzed for tritium and gamma emitters.

The tritium analyses, performed on quarterly composites of the monthly bay water samples,revealed evidence of tritium in one of the samples taken from the Discharge Area (sample codeWA2) during the 3rd quarter of the year.Figure 1 compares tritium observed in the plant discharge and intake with annual effluentreleases as reported in the Radioactive Effluent Release Report.Monthly analyses of bay water samples from both locations for gamma emitters exhibited nodetectable concentrations of any plant-related radionuclides.

lI.C.l.b Aquatic Organisms Twelve samples of aquatic organisms were obtained from four locations during the year.Samples of fish, when in season, are normally collected from the Discharge Area (sample codesIA1 and IA2) and from the Patuxent River (sample codes IA4 and IA5). As shown in Table B-2,two species of fish were sampled at both the plant discharge and the control point in the PatuxentRiver. Oyster samples were obtained quarterly from Camp Conoy (sample code IA3) andKenwood Beach (IA6).Figure 2 compares K-40 and Ag-II Om observed in oysters from Camp Conoy (IA3) with annualeffluent releases of Ag- I1Oim as reported in the Radioactive Effluent Release Report.Edible portion of the fish and oyster samples were analyzed for gamma emitters.

Gamma spectrometric analyses of the fish exhibited naturally occurring K-40 but no detectable concentrations of any plant-related radionuclides.

Oyster samples likewise exhibited naturally occurring K-40 but no detectable concentrations of any plant-related radionuclides.

II.C.l.c Shoreline SedimentSemiannual shoreline sediment samples are taken from one location during the year. Thislocation is Shoreline at Barge Road (sample code WB 1). The semiannual shoreline sedimentsamples obtained from this location were analyzed for gamma emitters.

Gamma spectrometric analyses of these samples exhibited naturally occurring radionuclides, butno detectable concentration of any plant-related radionuclides.

These samples were collected from five locations surrounding the plant. These locations are On Site before the Entrance to Camp Conoy (samplecode Al), Camp Conoy Road at the Emergency Siren (sample code A2), Bay Breeze Road(sample code A3), Route 765 at Lusby (sample codeA4),

and at the Emergency Operations Facility (sample code AS).II.C.2.a Air Particulate FiltersWeekly composite air particulate filter samples were collected from the five locations during theyear. These samples were analyzed for beta activity and gamma emitters.

Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic of background levels. The values ranged from 0.8 x 10-2 to6.7 x 10.2 pCi/mi3 for the indicator locations and 1.0 x 10-2 to 4.7 x 10"2 pCi/m3 at the controllocation.

The location with the highest overall mean of 2.4 x10-2 pCi/m3 was A4, Route 765 atLusby.Gamma spectrometric analyses of monthly composited air particulate samples exhibited nodetectable concentrations of any plant-related radionuclides in any of these samples.

Naturally occurring radionuclides, such as Be-7, were detected in nearly all samples.Figure 3 depicts the historical trends of beta activity.

II.C.2.b Air IodineWeekly composited charcoal cartridges (for trapping radioiodine species) were collected fromthe five locations during the year. These samples were analyzed for radioiodine species.Weekly radioiodine analyses of charcoal cartridges collected from all five locations exhibited nodetectable concentrations of 1- 131.Figure 3 depicts the historical trends of radioiodine.

monthly, when available, from various sampling locations near the plant during the normalgrowing season.lI.C.3.a Vegetation Vegetation samples were collected from three locations during the year. These locations areGarden Plot off Bay Breeze Road (sample codes IB, 13B2, and 1B3), On Site before the Entranceto Camp Conoy (sample codes IB4, IB5, and 1136), and the Emergency Operations Facility(sample codes 1B7, 1B8, and IB9). These samples were analyzed for gamma emitters, including analyses for 1- 13 1.All samples showed detectable amounts of naturally occurring K-40 and Be-7. Low level Cs-137 was identified in three of the 27 samples collected during the growing season. Samplescollected from the locations, On Site before the Entrance to Camp Conoy (sample codes 1134,1B6) and the Emergency Operations Facility (sample codes 1B8). The data are consistent withhistorical trends in low level Cs-137 attributable to weapons related Fallout in the soil. No plant-related radionuclides were found in any of these samples.II.C.4 Direct Radiation Direct radiation is measured by a network of TLDs in each overland sector surrounding the Plantboth at the plant boundary and at 4 miles from the Plant.TLDs were collected quarterly from twenty-three locations surrounding the plant. The twentyindicator locations are On Site Along the Cliffs (sample code DRI), Route 765 Auto Dump(sample code DR2), Giovanni's Tavern (sample code DR3), Route 765 across from White Sands(sample code DR4), John's Creek (sample code DR5), Lusby (sample code DR6), On Site beforethe Entrance to Camp Conoy (sample code DR7), On Site at Emergency Siren (sample codeDR8), Bay Breeze Road (sample code DR9), Decatur and Calvert Beach Roads (sample codeDR1O), Dirt Road off Mackall and Parran Roads (sample code DRI 1), Mackall and BowenRoads (sample code DR12), Wallville (sample code DR13), Rodney Point (sample code DRl4),Mill Bridge and Turner Roads (sample code DRI5), Appeal School (sample code DR16), CovePoint and Little Cove Point Roads (sample code DR 17), Cove Point (sample code DR18), LongBeach (sample code DR19), and On Site Near Shore (sample code DR20). The three controllocations are the Emergency Operations Facility (sample code DR21), Solomons Island (samplecode DR22), and Taylors Island, Anderson's Property (sample code DR23).The mean 90 day ambient radiation measured at the indicator locations was 12.68 mR andranged from 9.62 to 18.15 mR as reported in Table 2. The control locations showed a 90 daymean of 14.65 mR with ranges from 11.55 to 20.27 mR. The location with the highest overallmean of 18.25 was Taylors Island, Anderson's Property (sample code DR23), which ranged from17.38 to 20.27 mR. Figure 4 shows the historical comparison of the average monthly radiation levels per calendar year for TLDs on site, at four miles, and at the control locations.

CONCLUSION No man-made fission or activation by-products attributable to plant operations were observed inthe environment surrounding the plant during the year.Historical trends for tritium in bay water, Ag-i 1Oim and K-40 in oyster samples, nuclear falloutin the Calvert Cliffs area, and TLD data are depicted in Figures 1 through 4. As can be seenfrom these figures, the plant made no adverse radiological contributions to the surrounding environment.

To assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calculations were performed using the plant's effluent release data, on site meteorological data (see X/Q and D/Q values presented in Figures 5 and 6), and appropriate pathways.

Theresults of these dose calculations indicate:

Gaseous PathwaysA maximum thyroid dose of 1.50 x 10-2 mrem to a child via the plume, ground, vegetable, andinhalation pathways at 1.8 km SW of the containments at Calvert Cliffs. This is about 0.02% ofthe acceptable limit of 75 mrem/yr as specified in 40CFR190 and 10CFR72.104.

A maximum whole body gamma dose of 3.45 x 10-4 mrem to a child at 1.8 km SW of thecontainments at Calvert Cliffs. This is about 0.001% of the acceptable dose limit of 25 mrem/yras specified in 40CFR190 and I OCFR72.104.

A maximum dose to any other organ, in this case the skin, of 5.25 x 10-4 mrem to a child at 1.8km SW of the containments at Calvert Cliffs. This is about 0.002% of the acceptable dose limitof 25 mrem/yr as specified in 40CFR190 and 10CFR72.104.

Liquid PathwaysA maximum thyroid dose of 6.27 x 10-4 mrem to an adult for all liquid pathways, which is about0.0008 % of the acceptable dose limit of 75 mrem/yr as specified in 40CFR190 and10CFR72.104.

A maximum whole body dose of 8.26 x 10-4 mrem to an adult via all liquid pathways, which isabout 0.003 % of the acceptable dose limit of 25 mrem/yr as stated in 40CFR190 andI OCFR72.104.

A maximum dose to any other organ, in this case Bone, of 1.55 x 10-3 mrem to a child for allpathways, which is 0.006% of the acceptable dose limit of 25 mrem/yr specified in 40CFRI90and 1OCFR72.104.

13 January I -December 31, 2013Docket Nos. 50-317/50-318/72-8 Gaseous and Liquid Pathways CombinedA maximum thyroid dose of 1.56 x 10-2 mrem via liquid and gaseous pathways, which is about0.021% of the acceptable limit of 75 mrem/yr as specified in 40CFR190 and 1OCFR72.104.

A maximum whole body dose of 1.17 x 10-3 mrem via liquid and gaseous pathways, which isabout 0.005% of the acceptable limit of 25 mrem/yr as specified in 40CFRI90 andIOCFR72.104.

A maximum calculated dose to all other organs via liquid and gaseous pathways is equal to1.64 x 10-3mrem to the skin. This dose was about 0.007% of the allowable limit of 25 mrem/yras specified in 40CFRI90 and IOCFR72.104.

In all cases, the calculated doses are a small fraction of the applicable limits specified in40CFRI90 and 1OCFR72.104.

Therefore, it is concluded that the operation of Calvert Cliffs Units I and 2 producedradioactivity and ambient radiation levels significantly below the limits of the ODCM,40CFR190, and 1OCFR72.104.

There was no significant buildup of plant-related radionuclides in the environment due to the operation of the CCNPP in 2013.14 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 FIGURE 5Atmospheric Dispersion Around CCNPP Average Relative Air Concentrations (X/Q)02;PRiNIF ýFCRGF,I21PM POE .-lot LjoSHWWI 4-oo2E-0081E.009TýBOAO~~W-*Y0-6-Ygfl0 2 4'HODWSd -mHog WK4(1441ZIPTwwS0.0.',24615 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 FIGURE 6Atmospheric Dispersion Around CCNPP Average Relative Ground Deposition (D/Q)I*fpNjo~CJstiRoc~

18 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 III. INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAMIII.A. INTRODUCTION In August 1990 BGE initiated a program of additional radiological environmental monitoring around the site for the Independent Spent Fuel Storage Installation (ISFSI).

The first dry fuelstorage canister was loaded into the ISFSI in November of 1993 with more canisters beingloaded in subsequent years. During this operating period, no canisters of spent fuel weretransferred to the ISFSI. This area was also used as a temporary storage area for additional radioactive material.

Results of the monitoring program for the ISFSI for the current period are included in this report.This report presents the content of the ISFSI REMP (Table 3), the ISFSI sampling locations (Appendix A), the summary of the analytical results of the period (Table 4), and a compilation ofthe analytical data for the period (Appendix B). Interpretation of the data and conclusions arepresented in the body of the report.The ISFSI monitoring program is as described in this section of the report.The results were compared with that generated during the previous ISFSI pre-operational periods(Ref. 11) and the current and previous CCNPP REMP periods.

These results are discussed inmore detail in Section III. C.III.B. PROGRAMIII.B.1 Objectives The objectives of the radiological environmental monitoring program for the ISFSI are:a. To satisfy the community concern regarding the impact of the ISFSI on theenvironment,

b. To verify that radioactivity and ambient radiation levels attributable to operation of the ISFSI are within the limits specified in the Environmental Radiation Protection Standards as stated in 40CFRPart 190 and 1OCFR72.104,

c. To detect any measurable buildup of long-lived radionuclides in the environment due to the ISFSI,d. To monitor and evaluate ambient radiation levels around the ISFSI, ande. To determine whether any statistically significant increase occurs in theconcentration of radionuclides near the ISFSI.19 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 III.B.2 Sample Collection The locations of the individual sampling sites are listed in Table A-2 and shown in Figures A-4and A-5. All samples were collected by contractors to, or personnel of, Constellation EnergyNuclear Group personnel according to Constellation Energy Laboratory Procedures (Ref. 7, 8,12).IlI.B.3 Data Interpretation Many results in environmental monitoring occur at or below the minimum detectable activity(MDA). In this report, all results at or below the relevant MDA are reported as being "less than"the MDA value.III.B.4 Program Exceptions There were no program exceptions during this operating period.III.C. RESULTS AND DISCUSSIONS All the environmental samples collected were analyzed using Constellation Energy laboratory procedures (Ref. 8). The analytical results for this reporting period are presented in Appendix Band are also summarized for the period in Table 4. For discussion, the analytical results aredivided into three categories.

The categories are the Atmospheric Environment, the Terrestrial Environment, and Direct Radiation.

These categories are further divided into subcategories according to sample type (e.g., Vegetation and Soil for Terrestrial Environment).

III.C.1 Atmospheric Environment The atmospheric environment was monitored by analyzing air particulate filters.

These sampleswere collected from five locations surrounding the ISFSI.No source of airborne radioiodine exists for the ISFSI. Airborne radioiodine is, therefore, notconsidered in assessing the radiological impact of the ISFSI.llI.C.l.a Air Particulate FiltersWeekly composite air particulate filter samples were collected from five locations during theperiod. These locations are On Site before the Entrance to Camp Conoy (sample code A 1; incommon with the CCNPP REMP), Meteorological Station (SFA 1), CCNPP Visitor's Center(SFA2), NNW of the ISFSI (SFA3), and SSE of the ISFSI (SFA4). These samples wereanalyzed for beta radioactivity and gamma emitting radionuclides.

Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic of levels routinely observed in the REMP. These values rangedfrom 0.8 x 10-2 to 5.0 x 10-2 pCi/mi3 for the indicator locations and 0.9 x 102to 4.8 x 10-2 pCi/mi3for the control location.

The location with the highest overall mean of 2.3 x 10-2 pCi/mi3 wasSFAI, Meteorological Station.20 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 Gamma spectrometric analyses of monthly composited air particulate samples exhibited nodetectable concentrations of any plant-related radionuclides in any of these samples.

Naturally occurring radionuclides, such as Be-7, were detected in nearly all samples.IH.C.2 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation and soil collected quarterly from the vicinity of the air sampling locations for the ISFSI.If.C.2.a Vegetation Vegetation samples were collected quarterly from five locations during the year. These locations are: Meteorological Station (sample code SFB 1), CCNPP Visitor's Center (sample code SFB2),NNW of the ISFSI (sample code SFB3), SSE of the ISFSI (sample code SFB4), and On Sitebefore the Entrance to Camp Conoy (sample code SFB5).Vegetation samples were analyzed for gamma emitting radionuclides.

Cesium-137 was detectedin one sample at an indicator location.

The Cs-137 concentration was 72 +/- 27 pCi/kg. While thepresence of Cs-137 in this sample may be plant-related, this range is consistent with that found tobe due to the residual fallout from past atmospheric nuclear weapons testing.

The activities ofthis radionuclide are well below the federal limits established in 40CFRI90 and IOCFR72.104.

These are comparable to those observed in previous annual reporting periods for the CCNPPREMP and in the earlier pre-operational data for the ISFSI. No detectable concentrations ofplant-related radionuclides were found in any of these samples.

Naturally occurring radionuclides such as K-40 were detected in all samples.III.C.2.b SoilsSoil samples were collected quarterly from five locations surrounding the ISFSI in the vicinity ofthe air samplers.

These locations are: Meteorological Station (sample code SFS 1), CCNPPVisitor's Center (sample code SFS2), NNW of the ISFSI (sample code SFS3), SSE of the ISFSI(sample code SFS4), and On Site before the Entrance to Camp Conoy (sample code SFS5).Soil samples were analyzed for gamma emitting radionuclides.

Cesium-137 was detected ineight quarterly samples from both indicator and control locations.

The Cs-137 concentrations ranged from 52 +/- 25 to 200 + 40 pCi/kg. While the presence of Cs-137 in these samples may beplant-related, this range is consistent with that found to be due to the residual fallout from pastatmospheric nuclear weapons testing.

The activities of this radionuclide are well below thefederal limits established in 40CFR190 and 1OCFR72.104.

These are comparable to thoseobserved in previous annual reporting periods for the CCNPP REMLP and in the earlier pre-operational data for the ISFSI. No detectable concentrations of plant-related radionuclides werefound in any of these samples.

Naturally occurring radionuclides such as K-40 were alsodetected in all these samples.21 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 III.C.3 Direct Radiation Direct radiation is measured by a network of TLDs surrounding the ISFSI. These TLDs arecollected quarterly from nineteen locations surrounding the ISFSI, plus one control TLD locationat the Visitor's Center (sample code SFDR7). The locations include On Site before the Entranceto Camp Conoy (sample code DR7, common to both the CCNPP Program and the ISFSIProgram) and the Meteorological Station (sample code DR30, previously a location maintained for historical continuity.)

The other sampling locations are: SW of ISFSI (sample code SFDR1);NNW of ISFSI (sample code SFDR2); North of ISFSI (sample code SFDR3); NE of ISFSI(sample code SFDR4); East of ISFSI (sample code SFDR5); ESE of ISFSI (sample codeSFDR6); NNW of ISFSI (sample code SFDR8); SSE of ISFSI (sample code SFDR9); NW ofISFSI (sample code SFDRIO);

WNW of ISFSI (sample code SFDR1 1); WSW of ISFSI (samplecode SFDR12);

South of ISFSI (sample code SFDRI3);

SE of ISFSI (sample code SFDRI4);ENE of ISFSI (sample code SFDR15);

SSW of ISFSI (sample code SFDR16);

NNE of ISFSI(sample code SFDR17) and West of ISFSI (sample code SFDR18).

Sampling locations areshown on Figures A-4 and A-5.The mean 90 day ambient radiation measured at the ISFSI indicator locations was 28.80 mR andranged from 10.63 to 52.54 mR as reported in Table 4. The control location showed a 90 daymean of 13.90 mR and ranged from 12.29 to 15.23 mR. The location with the highest overallmean of 49.99 mR with a range of 47.67 to 52.54 mR was SFDR18, West of ISFSI. Thesereadings are consistent with those expected from the storage of spent fuel in the ISFSI. Acomparison of the average monthly radiation levels per calendar year of the ISFSI TLD datafrom the indicator locations with the ISFSI control location at the Visitor's Center, SFDR7, canbe seen in Figure 7.III.D. CONCLUSION Low levels of Cs-137 were observed in the environment surrounding the ISFSI during theperiod. The Cs-137 observations were attributed to fallout from past atmospheric weaponstesting.

No plant-related radionuclides were observed in the environs of the ISFSI.In general, the results in the following tables continue the historical trends previously observed atthe official sites of the CCNPP REMP.22 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 FIGURE 7Mean TLD Gamma Dose, ISFSI1210806E42010 J ~-4-*Control Location (SFDR7)--- ISFSI Mean (DR7, SFDR1-6, 8-18)Calendar Year0 --423 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 Table 3Synopsis of 2013 Calvert Cliffs Nuclear Power PlantIndependent Spent Fuel Storage Installation Radiological Environmental Monitoring ProgramSample TypeSampling, Frequency Number ofLocations NumberCollected AnalysisAnalysisFrequency' NumberAnalyzedAtmospheric Environment Air Particulates2 Direct Radiation Ambient Radiation Terrestrial Environment Vegetation W5260Gross BetaWMCGamma26060480Q20480TLDQQ520GammaQ20Soil Q 5 20 Gamma Q 201 W=weekly, M=monthly, Q=quarterly, SA=semiannual, A=annual, C=composite 2 Beta counting is performed after >72 hour decay, Gamma spectroscopy performed on monthly composites of weekly samples24 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 Table 4Annual Summary of Radioactivity in the Environs of theCalvert Cliffs Nuclear Power Plant Independent Spent Fuel Storage Installation Medium orPathway Sampled(Unit ofMeasurement)

Itconsists of Table C-1 which is a compilation of the results of the Constellation Energylaboratory's participation in an interlaboratory comparison program with Environmental Resource Associates (ERA) located in Arvada, Colorado and Analytics, Inc. located in Atlanta,Georgia.

It also includes Table C-2, which is a compilation of the results of the Constellation Energy laboratory's participation in a split sample program with Teledyne Brown Engineering located in Knoxville, Tennessee, and Table C-3, which is a list of typical MDAs achieved byTeledyne Brown for Gamma Spectroscopy.

All the Constellation Energy laboratory's results contained in Table C-i generally agree with theinterlaboratory's comparison results within the range of +/-2a of each other. One result for Zinc inERA Study RAD 95 was just outside the acceptable range but did pass the NRC Resolution TestCriteria'.

In addition, all the sets of intercomparison results in the table are in full agreement, and when appropriate, they were further evaluated using the NRC Resolution Test Criteria.

Theuncertainties for the Constellation Energy laboratory's results and Analytics' results are +/-2owhile the ERA laboratory's uncertainty is based on USEPA guidelines 2.All the results contained in Table C-2 agree within the range of +/-2a of each other with theirrespective Constellation Energy laboratory

original, replicate and/or Teledyne BrownEngineering's split laboratory

samples, except for the comparisons of one bottom sedimentsample and a fish sample involving Cs-137 results.

The original and replicate analysis of thebottom sediment sample from WBS4 collected on 6/19/13 do agree within +/-2a of each otherhowever the replicate does not agree within +/-2a of the split lab results.

The original analysis ofthe fish sample from IA2 collected on 8/15/13, and the split lab sample do agree as below MDAand the replicate analysis of the fish sample has a low level positive result near the MDA butoutside +/-2a of the respective QC comparison samples analyzed.

These minor discrepancies, which have been observed in previous reporting

periods, are most probably due to countingstatistics and/or the non-homogeneous nature of this type of sample. Other samples whosenature generally preclude sample splitting are marked "**" in the Split Analysis column.lNRC Inspection Manual, Inspection Procedure 84750, March 15, 19942 National Standards for Water Proficiency Testing Studies Criteria

A table listing the raw data of this survey and adiscussion of the results are included in thisappendix.

Table D-1Land Use SurveyDiscussion A Land Use Survey was conducted to identify, within a distance of 5 miles, the location of thenearest milk animal, the nearest residence, andthe nearest garden greater than 50 m' in each ofthe nine sectors over land. A detailed description of the Land Use Survey is given in a separatedocument (Ref. 9). The position of the nearestresidence and garden in each sector out to 5 milesis given in the adjacent table. There are noanimals producing milk for human consumption within the 5 mile radius. The nearest garden/resident in the NW and SSE sectors have changedsince 2012 and are still located within the 5-mileradius.Distance From Plant(miles)Sector Residence GardenSE 1.5 1.5SSE 1.6 2.4*S 1.6 1.6SSW 1.5 1.6SW 1.1 1.1WSW 1.3 1.4W 1.3 1.3WNW 2.7 2.7NW 2.0 2.1*The closest residence to the plant is situated in the SW sector and the nearest garden is also in theSW sector, which is one of the least prevalent wind directions.

In the S, SSE, and SE sectors,there is the highest probability of wind blowing from the direction of the plant. The two gardensused for vegetable samples by the REMP have been placed in the sectors with the highest X/Q.One sampling garden is located in the S sector at a distance of 0.4 miles, and another is situatednear the site boundary in the SSE sector at a distance of 1.6 miles from the plant. These twosampling sites are considered good indicator locations for radioactive depositions around theplant.The dose assessment using this operating period meteorological data was performed, and nosignificant impact from the plant was found.*GPS was used to determine distance from the central point between the two containment buildings.

74 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 APPENDIX EAdditional Samples and Analysis ResultsAppendix E is a presentation of the analytical results for additional samples collected in theenvirons of CCNPP. These extra samples are not required by the ODCM (Ref. 6). Table E-1 liststhe locations of all the additional samples and the remaining tables in this appendix provide theresults.

Some of these samples were collected and analyzed to maintain the historical continuity for samples and sampling pathways discontinued when the Environmental Technical Specifications were changed in March, 1985.Table E-4 through E-10 contain analytical results for samples taken from the various radiological pathways (i.e., aquatic, atmospheric, terrestrial, and direct radiation) surrounding the plant. Ingeneral these results continue the historical trends previously observed in the official sites of theCCNPP REMP and ISFSI.Table E- 11 shows the direct radiation readings from TLDs placed at the perimeter of the ResinStorage Area which is a temporary waste resin storage and cask transfer area located to the westof the ISFSI facility.

The TLD values are somewhat higher than those in the REMP program dueto their proximity to this source of the radiation.

However, when the direct radiation readings forthe Resin Storage Area are compared with those from the ISFSI and Site Boundary TLDs, it isapparent that temporary storage of spent resin and cask transfers are having no significant, measurable effect on the environs surrounding CCNPP.The NEI Industry Groundwater Protection Initiative was established to determine the potential impact nuclear power plants may have on the surrounding environment due to unplanned releases of radioactive liquids.

Under the Groundwater Protection Initiative, groundwater monitoring is accomplished through routine sampling of the water table around the plant andanalysis for gamma and tritium.Groundwater samples were collected from 17 on-site piezometer tubes in 2013. Eight of the 17were new piezometers added at Calvert Cliffs during this reporting period. These were identified as Piezometers 23 -30 on Figure E-1, Site Map Groundwater Monitoring Wells. A piezometer tube is a shallow monitoring well which allows access to groundwater at a depth ofapproximately 40 feet beneath the site. Of the piezometer tubes sampled, only # 11 piezometer showed any plant-related activity.

This activity was previously identified and evaluated inDecember of 2005. The activity consists of tritium originating from normal radiological wastedischarges and was previously reported in the Annual Radioactive Release Reports.

The tritiumcontamination is contained on site. No drinking water has been affected; the groundwater at thislocation does not impact any drinking water pathway.

The 2013 analysis results for tritium areshown in Table E-I 1, and analysis results for gamma emitting radionuclides are shown in TableE-12.75 January 1 -December 31, 2013Docket Nos. 50-317/50-318/72-8 TABLE OF CONTENTS

To clarify the 2011 AREOR report for theREMP and the ISFSI, this Appendix is provided as errata.Section 1I.B.4 Program Exceptions, page 5, read "There were no program exceptions during thisoperating period,"

and the section should read:Air sampler power outages at On Site Before Entrance to Camp Conoy (samplecode Al) during the weeks beginning August 22 and September 5 resulted in theloss of air samples available for concentrations of beta emitters in airparticulates analyses.

The air sample from the week beginning September 5 alsowas unavailable for analysis of concentration of Iodine-131 in filtered airbecause of this power outage. These program exceptions have been entered intothe site's Corrective Action Program to ensure they do not recur.Three direct radiation dosimeters, one in the 1st quarter and two in the 3rdquarter, were found missing from ODCM sampling locations during thisoperating period.
