........ 92 IV I.SUMMARY January I -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 During 2016, Calvert Cliffs Nuclear Power Plant (CCNPP) Units I and 2, a total of 3614 radiological analyses were performed and the analytical results reviewed.

Most of these analyses were performed to satisfy the requirements of the Off site Dose Calculation Manual (ODCM) (Ref. 6), the Environmental Technical Specifications (Ref. 5) and the Independent Spent Fuel Storage Installation (ISFSI) Technical Specifications (Ref. 10). Some of these samples, although not required by either the ODCM or the Technical Specifications

, were collected to maintain our commitments to the surrounding community and to maintain historical continuity of the CCNPP Radiological Environmental Monitoring Program (REMP) that started in 1970. The entire monitoring program in place around CCNPP is divided into three parts: the original 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 659 radiochemical analyses were performed on 591 environmental samples and 546 thermoluminescent dosimeters (TLDs) were analyzed for ambient radiation exposure rates as part of the original REMP. These analyses were performed to satisfy the requirements of the ODCM (Ref. 6) and the Environmental Technical Specifications (Ref. 5). For the ISFSI monitoring program, 365 radiochemical analyses were performed on 305 environmental samples, 64 of which were in common with the original REMP. In addition, 480 TLDs, 24 in common with the original REMP, were analyzed for ambient radiation exposure rates. These analyses were performed to satisfy the requirements of the ODCM (Ref. 6) and the ISFSI Technical Specifications (Ref. I 0). In addition, 746 analyses were performed on 637 additional environmental samples, and 480 additional TLDs were analyzed for ambient radiation exposure rates. And lastly, 343 radiochemical analyses were performed on 245 quality assurance samples and 132 quality assurance TLDs were analyzed as part of an internal and external quality assurance program associated with Teledyne Brown Engineering.

Laboratory intercomparison samples obtained from Environmental Resource Associates (ERA) and Analytics

' Inc. were also analyzed. 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 glass fiber filters and charcoal cartridges

, respectively. The particulate filters were analyzed for beta activity and gamma emitting nuclides. The charcoal cartridges were analyzed for airborne gaseous radioiodine

.

January 1 -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 Samples from the terrestrial environment consisted of vegetation and soi I samples collected and analyzed for gamma emitters.

Vegetation samples for the original REMP were also analyzed for I-131. Measurement s of direct radiation

, as required by the ODCM, were performed by analyzing TLDs from forty locations surrounding CCNPP and the ISFSI. Natural radioactivity was detected in essentially all 3340 radiological analyses performed.

Low levels of man-made fission products were also observed in 7 of these analyses for the CCNPP REMP. All of these observations were attributed to fallout from past atmospheric weapons testing.

Detailed discussions about the results of these analyses are contained in the body of this report. To assess the plant's contribution to the radiation levels of the ambient environment

, dose calculations were performed using 2016 data from the plant's effluent releases, 2016 on-site meteorological data, and appropriate pathways.

The results of these dose calculations indicate: a. a maximum thyroid dose of 6.13 x I 0-3 mrem via liquid and gaseous pathways, which is about 0.008% of the acceptable limit of 75 mrem/yr as specified in 40CFR 190 "Environmental Radiation Protection Standards for Nuclear Power Operations" and 1OCFR72.104

, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste"; b. a maximum whole body dose of 3.21 x 10*3 mrem via liquid and gaseous pathways, which is about 0.013% of the acceptable limit of 25 mrem/yr as specified in both 40CFR190 and I OCFR72.104

and c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 5.80 x 10*3 mrem to the liver. This dose is about 0.023% of the allowable limit of 25 mrem/yr as specified in both 40CFRI 90 and 10CFR72.104.

Thus, it is concluded based upon the levels of radioactivity observed and the various dose calculations performed

, that CCNPP Units I and 2 and the ISFSI did not cause any significant radiological impact on the surrounding environment.

2 January I -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 II. CAL VERT CLIFFS NUCLEAR POWER PLANT RADIOLOGICAL ENVIRONMENT AL MONITORING PROGRAM II.A. INTRODUCTION The REMP has been conducted in the vicinity of CCNPP since the summer of I 970. The Calvert Cliffs site is an operating nuclear generating station consisting of two 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 went into commercial operation April 1, 1977. The location of the plant in relation to local metropolitan areas is shown on Figure A-1. Results of the monitoring program for the pre-operational period have been reported in a series of documents (Ref. 1-4 ). The results from previous operational periods are contained in annual reports 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 I), the sampling locations (Appendix A), the summary 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), and a compilation of the analytical data for extra samples collected (Appendix E). 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 with that generated in previous periods whenever possible to evaluate the environmental radiological impact of CCNPP Units 1 and 2. 11.B. PROGRAM 11.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 plant operation are within the limits specified in the ODCM (Ref. 6) and the Environmental Radiation Protection Standards as stated in 40CFR 190, b. To detect any measurable buildup of long-lived radionuclides in the environment

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

3 11.B.2 Sample Collection January l -December 31, 2016 Docket Nos. 50-3 I 7 /50-318/72-8 The locations of the individual sampling stations are listed in Table A-1 and shown in Figures A-2 and A-3. All samples were collected by contractors to, or personnel of Exelon Generation according to CCNPP Procedures (Ref. 7, 8 and 12). 11.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. 11.B.4 Program Exceptions Sample A5 at the Emergency Operations Facility, was out of operation due to a power outage which required a reset of the breaker, and insufficient sample was collected due to low flow for the weeks of February 22nd to March 7th. This program exception has been entered into the site's Corrective Action Program to ensure it does not recur. Direct radiation dosimeters

, in the 4th quarter, were found missing from an ODCM (Ref. 6) sampling location during this operating period. Direct radiation dosimeters were missing due to the removal of the pole they were mounted on at Cove Point and Little Cove Point Roads sampling location (sample code DR 17) in the 4th quarter of this operating period. No substitute samples were collected in lieu of the samples not taken from these locations.

New dosimeters ere deployed on an alternate pole about 35 feet away in the same sector. Direct radiation dosimeters were replaced at these locations for the purposes of monitoring direct radiation per the ODCM (Ref. 6), and these program exceptions were entered into the site's Corrective Action Program.

11.C. RES UL TS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using Exelon Industrial Services laboratory procedures (Ref. 8) with the exception of Tritium analyzed by Gel Laboratories LLC.(Ref. 14). The analytical results for this reporting period are presented 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

, the Atmospheric Environment

, the Terrestrial Environment

, and Direct Radiation.

These categorie s are further divided into subcategories according to sample type (e.g., Bay Water, Aquatic Organisms

, etc., for the Aquatic Environment)

. Il.C.1 Aquatic Environment The aquatic environment surrounding the plant was monitored by analyzing samples of bay water, aquatic organisms

, and shoreline sediment.

These samples were obtained from various sampling locations on the Chesapeake Bay near the plant. 4 11.C.1.a Bay Water January 1 -December 31, 2016 Docket Nos. 50-317/50-318/72-8 Monthly bay water samples were taken from two locations during the year. These locations are the 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 were analyzed for tritium and gamma emitters. The tritium analyses, performed on quarterly composites of the monthly bay water samples, revealed no evidence of tritium in any of the samples taken from either site throughout the year. Figure 1 compares tritium observed in the plant discharge and intake with annual effluent releases as reported in the Radioactive Effluent Release Report. Monthly analyses of bay water samples from both locations for gamma emitters exhibited no detectable concentrations of any plant-related radionucl ides. 11.C.1.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 codes IAl 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 Patuxent River. Oyster samples were obtained quarterly from Camp Conoy (sample code IA3) and Kenwood Beach (IA6). Figure 2 compares K-40 and Ag-I I Om observed in oysters from Camp Conoy (lA3) with annual effluent releases of Ag-11 Om 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

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

Gamma spectrometric analyses of these samples exhibited naturally occurring radionuclides

, but no 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 (sample code Al), Camp Conoy Road at the Emergency Siren (sample code A2), Bay Breeze Road (sample code A3), Route 765 at Lusby (sample code A4), and at the Emergency Operations Facility (sample code A5). 11.C.2.a Air Particulate Filters Weekly composite air particulate filter samples were collected from the five locations during the year. 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 to 5.3 x 10-2 pCi/m3 for the indicator locations and l .O x 10-2 to 3.6 x 10-2 pCi/m3 at the control location.

The location with the highest overall mean of 2.0 x10-2 pCi/m3 was A2, Camp Conoy Siren, an indicator location, and the mean for all the indicator locations was 2.0 x 10-2 pCi/m3. Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples. Naturally occurring radionuclides

, such as Be-7, were detected in nearly all samples.

These locations are Garden Plot off Bay Breeze Road (sample codes lB 1, IB2, and IB3), On Site before the Entrance to Camp Conoy (sample codes IB4, IB5, and IB6), and the Emergency Operations Facility (sample codes IB7, IB8, and IB9). These samples were analyzed for gamma emitters, including analyses for 1-131. All samples showed detectable amounts of naturally occurring K-40 and Be-7. No plant related radionuclides were found in any of these samples.

11.C.4 Direct Radiation Direct radiation is measured by a network of TLDs in each overland sector surrounding the Plant both at the plant boundary and at 4 miles from the Plant. TLDs were collected quarterly from twenty-three locations surrounding the plant. The twenty indicator locations are On Site Along the Cliffs (sample code DR 1 ), 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 DRS), Lusby (sample code DR6), On Site before the Entrance to Camp Conoy (sample code DR7), On Site at Emergency Siren (sample code DR8), Bay Breeze Road (sample code DR9), Decatur and Calvert Beach Roads (sample code DR I 0), Dirt Road off Mackall and Parran Roads (sample code DR 11 ), Mackall and Bowen Roads (sample code DR12), Wallville (sample code DR13), Rodney Point (sample code DR14), Mill Bridge and Turner Roads (sample code DR 15), Appeal School (sample code DR 16), Cove Point and Little Cove Point Roads (sample code DR 17), Cove Point (sample code DRl 8), Long Beach (sample code DRl 9), and On Site Near Shore (sample code DR20). The three control locations are the Emergency Operations Facility (sample code DR21 ), Solomons Island (sample code DR22), and Taylors Island, Anderson's Property (sample code DR23). The mean 90 day ambient radiation measured at the indicator locations was 1 1.17 mR and ranged from 8.75 to 14.77 mR as reported in Table 2. The control locations showed a 90 day mean of 12.78 mR with ranges from 10.21 to 15.45 mR. The location with the highest overall mean of 14.85 was Taylors Island, Anderson's Property (sample code DR23) which ranged from 13.52 to 15.45 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.

A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data shows no plant-related contribution to the measured direct radiation exposure.

/72-8 No man-made fission or activation by-products attributable to plant operations were observed in the environment surrounding the plant during the year. Historica l trends for tritium in bay water, Ag-11 Om and K-40 in oyster samples, nuclear fallout in the Calvert Cliffs area, and TLD data are depicted in Figures 1 through 4. As can be seen from 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 2016 effluent release data, on site meteorological data (see X/Q and D/Q values presented in Figures 5 and 6), and appropriate pathways. Carbon 14 dose in not included here and is instead reported in the Annual Radiological Effluents Release Report. The results of these dose calculations indicate:

Gaseous Pathways A maximum thyroid dose of 4.33 x 10*3 mrem to a child via the plume, ground, vegetable

, and inhalation pathways at 1.1 miles SW of the containments at Calvert Cliffs. This is about 0.006% of the acceptable limit of 75 mrem/yr as specified in 40CFR 190 and 1OCFR72.l04. A maximum wh le body gamma dose of 3.18 x l 0*4 mrem to a child at 1.1 miles SW of the containment* at alv rt Cliffs. This is about 0.001 % of the acceptable dose limit of 25 mrem/yr as sp ci 1ed

  • n 40CFR 190 and 1OCFR72.104. A m imu 11 ose to any other organ, in this case the skin, of 3.35 x 10*4 mrem to a child at 1.1 mile SW oft' e contai ments at Calvert Cliffs. This is about 0.001% ofthe acceptable dose limit of 25 mrem/yr a specified in 40CFR 190 and 1OCFR72.104. Liquid Path ays A maximum thyroid d se of 1.80 x 10*3 mrem to a teen for all liquid pathways, which is about 0.002 % of the acceptable dose limit of 75 mrem/yr as specified in 40CFR 190 and 1OCFR72.l04.

A maximum whole body dose of2.89 x 10*3 mrem to a teen via all liquid pathways, which is about 0.012 % of the acceptable dose limit of 25 mrem/yr as stated in 40CFR 190 and 10CFR72.104.

A maximum dose to any other organ, in this case liver, of 5.46 x I 0*3 mrem to a teen for all pathways, which is 0.022% of the acceptable dose limit of 25 mrem/yr specified in 40CFR190 and 1OCFR72.l04. 12 Gaseous and Liquid Pathways Combined January l -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 A maximum thyroid dose of6.13 x 10-3 mrem via liquid and gaseous pathways, which is about 0.008% of the acceptable limit of 75 mrem/yr as specified in 40CFR190 and 1OCFR72.l04.

A maximum whole body dose of 3.21x10-3 mrem via liquid and gaseous pathways, which is about 0.013% of the acceptable limit of 25 mrem/yr as specified in 40CFRI 90 and 1 OCFR72.104.

A maximum calculated dose to all other organs via liquid and gaseous pathways is equal to 5.80 x 1 o-3mrem to the liver. This dose was about 0.023% of the allowable limit of 25 mrem/yr as specified in 40CFR 190 and I OCFR 72.104. In all cases, the calculated doses are a small fraction of the applicable limits specified in 40CFR190 and 1OCFR72.l04. Therefore

, it is concluded that the operation of Calvert Cliffs Units 1 and 2 produced radioactivity and ambient radiation levels significantly below the limits of the ODCM, 40CFR190, and I OCFR 72. l 04. There was no significant buildup of plant-related radionuclides in the environment due to the operation of the CCNPP in 2016. 13 ---------

INTRODUCTION ln August 1990 BGE initiated a program of additional radiological environmental monitorin g around the site for the Independent Spent Fuel Storage Installation (ISFSI). The first dry fuel storage canister was loaded into the ISFSI in November of 1993 with more canisters being loaded in subsequent years. During 2016, three additional canisters of spent fuel were transferred to the ISFSI. 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 of the analytical data for the period (Appendix B). Interpretation of the data and conclusions are presented 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 ( ef.11) and the current and previous CCNPP REMP periods.

These results are discussed in m re detail in Sec ion Ill. C. III.B. PROGR _ Ill.B.1 Objecti cs The objectives of the radiological environmenta l monitoring program for the ISFSI are: a. To atisfy the community concern regarding the impact of the ISFSI on the environment, 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 radionucli des in the environment due to the ISFSl, d. To monitor and evaluate ambient radiation levels around the ISFST, and e. To determine whether any statistically significant increase occurs in the concentration of radionuclides near the ISFSL 111.B.2 Sample Collection 18 January I -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 The locations of the individual sampling sites are listed in Table A-2 and shown in Figures A-4 and A-5. All samples were collected by contractors to, or personnel of, Exelon Industrial Services personnel according to Exelon Industrial Services Laboratory Procedures (Ref. 7, 8, 12). llI.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. 111.B.4 Program Exceptions There were no program exceptions during this operating period. 111.C. RESULTS AND DISCUSSIONS All the environmental samples collected were analyzed using Exelon Industrial Services laboratory procedure (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 are divided 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).

IH.C.1 Atmo pheric Environment The atmospheric environment was monitored by analyzing air particulate filters.

These samples were collec ed from five locations surrounding the lSFSl. No source of airborne radioiodine exists for the ISFSl. Airborne radioiodine is, therefore

, not con "dered in assessing the radiological impact of the ISFSl. 111.C.1.a Air Particulate Filters Weekly composite air particulate filter samples were collected from five locations during the period. These locations are On Site before the Entrance to Camp Conoy (sample code A 1; in common with the CCNPP REMP), Meteorological Station (SFAI), CCNPP Visitor's Center (SFA2), NNW of the lSFSI (SFA3), and SSE of the ISFSI (SFA4). These samples were analyzed 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 ranged from 0.8 x 10*2 to 3 .8 x I 0*2 pCi/m3 for the indicator locations and 1.0 x I o*2to 4.0 x I 0*2 pCi/m3 for the control location.

The location with the highest overall mean of 2.0 x 10*2 pCi/m3 was A I, Entrance to Camp Conoy. 19 January 1 -December 31, 2016 Docket Nos. 50-317/50-318/72-8 Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclid es in any of these samples.

Naturally occurring radionuclides

, such as Be-7, were detected in nearly all samples. 111.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 ISFSl. 111.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 lSFSl (sample code SFB4), and On Site before the Entrance to Camp Conoy (sample code SFB5). Vegetation samples were analyzed for gamma emitting radionuclides.

No detectable concentrations of plant-relat ed radionuclides were found in any of these samples. Naturally occurring radionuclides such as K-40 were detected in all samples. llJ.C.2.b Soils Soil amples were col cted quarterly from five locations surrounding the ISFSl in the vicinity of the air samplers. These locations are: Meteorological Station (sample code FS I), CCNPP Visitor's Center ( *:unple code SFS2), NNW of the JSFSI (sample code SFS3), E of the ISFSI (sample code F , ), und On ite before the Entrance to Camp Conoy (sample code FS5). Soil m les wer *analyzed for gamma emitting radionuclides

. Cesium-13 7 was detected in six quarterly samples from both indicator and control locations. The Cs-137 concentrations ranged from 73 +/- 27 to I 2 +/- 37 pCi/kg. While the presence of Cs 137 in these samples may be related, this range i.* consistent with that found to be due to the residual fallout from past atmospheric nuclear weapons testing.

The activities of this radionuclide are well below the ederal .imits established in 40CFR 190 and I OCFR72. I 04. These are comparable to those observed in previous annual reporting periods for the CCNPP REMP and in the earlier operational data for the ISFSI. No detectable concentrations of plant-related radionuclides were found in any of these samples. Naturally occurring radionuclides such as K-40 were also detected in all these samples. 111.C.3 Direct Radiation Direct radiation is measured by a network of TLDs surrounding the ISFSl. These TLDs are collected quarterly from nineteen locations surroundin g the ISFSl, plus one control TLD location at the Visitor's Center (sample code SFDR7). The locations include On Site before the Entrance to Camp Conoy (sample code DR7, common to both the CCNPP Program and the ISFSI Program) and the Meteorological Station (sample code DR30, previously a location maintained for historical continuity.) The other sampling locations are: SW of ISFSl, (sample code SFDR I): NNW of ISFSI, (sample code FDR2); North of ISFSI, (sample code SFDR3); NE of 20 January l -December 31, 2016 Docket Nos. 50-317/50-318/72-8 ISFSI, (sample code SFDR4); East of ISFSI, (sample code SFDR5); ESE of ISFSl, (sample code SFDR6); NNW of ISFSI, (sample code SFDR8); SSE of ISFSI, (sample code SFDR9); NW of ISFSI, (sample code SFDR10);

WNW of ISFSI, (sample code SFDRl l); WSW ofISFSI, (sample code SFDR12);

South of ISFSI, (sample code SFDR13);

SE oflSFSI, (sample code SFDR14);

ENE of ISFSI, (sample code SFDRl5);

SSW ofISFSI, (sample code SFDR16);

NNE of ISFSI, (sample code SFDRl 7) and West of ISFSI, (sample code SFDRl 8). Sampling locations are shown on Figures A-4 and A-5. The mean 90 day ambient radiation measured at the ISFSI indicator locations was 27.59 mR and ranged from 9.09 to 44.58 mR as reported in Table 4. The control location showed a 90 day mean of 11.89 mR and ranged from I 0.65 to 12.51 mR. The location with the highest overall mean of 42.52 mR with a range of 40.76 to 44.58 mR was SFDRl 6, SSW of ISFSI. These readings are consistent with those expected from the storage of spent fuel in the ISFSI. A comparison of the average monthly radiation levels per calendar year of the ISFSI TLD data from the indicator locations with the ISFSI control location at the Visitor's Center, SFDR7, can be seen in Figure 7. 111.D. CONCLUSION Low levels of Cs-137 were observed in the environment surrounding the I. FSI during the period. The Cs-137 observatio ns were attribuced to fallout from past atmospheric weapons testing. No plant-related radionuclid es were ob erved in the environs of the ISFS!. In general, the results in the following tables continue the historical trends previously observed at the official ites of th CCNPP REMP. 21 I L __ _ FIGURE 7 _________________

's quality assurance program. It consists of Table C-1 which is a compilation of the results of the EIS Laboratory

'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 EIS 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 MD As achieved by Teledyne Brown for Gamma Spectroscopy.

All the EIS Laboratory

's results contained in Table C-1 generally agree with the intercomparison laboratory's results within the range of +/-2 CJ of each other. In addition, all the sets of intercomparison results in the table are in full agreement when they were further evaluated using the NRC Resolution Test Criteria1* The uncertainties for the Constellation Energy laboratory's results and Analytics

' results are +/-2CJ while the ERA laborator y's uncertainty is based on USEPA guidelines2. All the results contained in Table C-2 agree within the range of +/-2CJ of each other with their respective EIS Laboratory original, replicate and/or Teledyne Brown Engineering's split laboratory samples.

The comparisons of two samples involving Cs-13 7 results: bottom sediment sample at WBS4 collected on 6/14/16 and soil at SFS5 collected on 9/26/16 were in full agreement.

The original and replicate analysis of the bottom sediment sample at WBS4 collected on 6/14/16 agrees within +/-2 CJ of each other. Low level Cs-137 was observed in the comparison set for SFS5 collected on 9/26/16 in the original, duplicate and split lab sample. Results are in agreement within +/-2 CJ of each other. Other samples whose nature generally preclude sample splitting are marked"**" in the Split Analysis column. 1 NRC Inspection Manual, Inspection Procedure 84750, March 15, 1994 2 National Standards for Water Proficiency Testing Studies Criteria Document, December 1998 57 Table January 1 -December 31, 2016 Docket Nos. 50-317/50-318/72-8 TABLE OF CONTENTS

Docket Nos. 50-317 /50-318/72-8 Appendix D contains the results of a Land Use Survey conducted around Calvert Cliffs Nuclear Power Plant during this operating period. A table listing the raw data of this survey and a discussion of the results are included in this appendix.

Table D-1 Discussion A Land Use Survey was conducted to identify, within a distance of 5 miles, the location of the nearest milk animal, the nearest residence

, and the nearest garden greater than 50 m2 in each of the nine sectors over land. A detailed description of the Land Use Survey is given in a separate document (Ref. 9). The position of the nearest residence and garden in each sector out to 5 miles is given in the adjacent table. There are no animals producing milk for human consumption within the 5 mile radius. The nearest garden location has changed in the SSW, Wand WSW Sector SE SSE s SSW SW WSW w WNW NW sectors since 2015 and are still located within the 5-mile radius. Land Use Survey Distance From Plant (miles) Residence 1.5 1.6 1.6 1.5 I. I 1.3 1.3 2.7 2.0 Garden 1.5 4.2 1.6 1.4 I. I 1.8 1.8 2.7 2.1 The closest residence is situated in the SW sector and the nearest garden is also in the SW sector, which is one of the least prevalent wind directions

. ln the S, SSE, and SE sectors, there is the highest probability of wind blowing from the direction of the plant. The two gardens used for vegetable samples by the REMP have been placed in the sectors with the highest D/Q. One sampling garden is located in the S sector at a distance of 0.4 miles, and another is situated near the site boundary in the SSE sector at a distance of 1.6 miles from the plant. These two sampling sites are considered good indicator locations for radioactive depositions around the plant. The dose assessment using this operating period meteorological data was performed

, and no significant impact from the plant was found. 75 APPENDIXE January I -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 Additional Samples and Analysis Results Appendix Eis a presentation of the analytical results for additional samples collected in the environs of CCNPP. These extra samples are not required by the ODCM (Ref. 6). Table E-1 lists the locations of all the additional samples and the remaining tables in this appendix provide the results.

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. In general these results continue the historical trends previously observed in the official sites of the CCNPP REMP and ISFSI. Table E-10 shows the direct radiation readings from TLDs placed at the perimeter of the Resin Storage Area which is a temporary waste resin storage and cask transfer area located to the west of the ISFSI facility.

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

However, when the direct radiation readings for the Resin Storage Area are compared with those from the ISFSI and Site Boundary TLDs, it is apparent 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 Lnitiative 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 and analysis for gamma and tritium.

Groundwater samples were collected from 17 on-site piezometer tubes and three subsurface manholes in 2016. In addition four precipitation and two surface water locations were monitored.

The Piezometers 1 I -30 are shown on Figure E-1, Site Map Groundwater Monitoring Wells. Figure E-2, Site Map R W Locations

, shows precipitation collection sites. A piezometer tube is a shallow monitoring well which allows access to groundwater at a depth of approximately 40 feet beneath the site. Of the locations sampled, only# 11 piezometer

, MH28, and MH30 showed any plant-related activity. This activity was previously identified and evaluated in December of 2005. The activity consists of tritium originating from normal radiological waste discharges and was previously reported in the Annual Radioactive Release Reports.

The tritium contamination is contained on site. No drinking water has been affected; the groundwater at this location does not impact any drinking water pathway.

The 2016 analysis results for tritium are shown in Table E-1 I, and analysis results for gamma emitting radionuclides are shown in Table E-12. 76 Table January l -December 31, 2016 Docket Nos. 50-317 /50-318/72-8 TABLE OF CONTENTS
