Appendix H Annual Radiological Groundwater Protection Program Report (ARGPPR) 1 I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP) conducted for Exelon's Braidwood Station covers the period January 1, 2014 through December 31, 2014. During that time period 1, 574 analyses were performed on 1

, 3 47 samples. In assessing all the data g athered for this report and comparing these results with preoperational data, it was concluded that the operation of Braidwood Station had no adverse radiological impact on the environment.

Surface, public, and ground/well water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Surface water and public water samples were also analyzed for concentrations of gross beta. Gross beta and tritium activities detected were consistent with those detected in previous years. No fission or activation products were detected. As part of an effort to implement industry best practices, both gaseous and liquid station effluents were evaluated for all 10CFR61 required nuclides. Nuclides exceeding 1% relative abundance in the waste stream were added to the list of nuclides that Teledyne Brown evaluates in potentially impacted REMP matrices. For Braidwood Station, Ni-63 exceeds 1% relative abundance in the radwaste resins. Occasionally, Ni-63 is observed in liquid release tank quarterly composites, therefore, beginning in the fall of 2013 the station requested that Ni

-63 be evaluated in the downstream surface water, sediment, and fish analyses. Ni

-63 has not been observed in downstream surface water.

Fish (commercially and/or recreationally important species) and sediment samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected in fish. Nickel-63 was not detected in any fish or sediment samples analyzed.

T wo sediment sample s had Cs-137. The concentration was consistent with levels observed during the preoperational years. No plant produced fission or activation products were found in sediment.

Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. No fission or activation products were detected

. High sensitivity I

-131 analyses were performed on weekly air samples. All results were less than the minimum detectable concentration for I

-131. Cow milk samples were analyzed for concentrations of I-131 and gamma emitting nuclides.

Iodine-131 was not detected in any milk sample s. Concentrations of naturally occurring K

-40 were detected. No fission or activation products were found and all required LLDs (Lower Limit of Detection) were met. Food Product samples were analyzed for concentrations of gamma emitting nuclides. No plant produced fission or activation products were detected

. Environmental gamma radiation measurements were performed quarterly using 2 Optically Stimulated Luminescence Dosimeters (OS LD). Beginning in 2012 , Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry were deployed and Thermo

-luminescent Dosimetry (TLD) were discontinued. This change may result in a step change in readings , up or down, depending on site characteristics. The relative comparison to control locations remains valid.

OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation

).

II. Introduction The Braidwood Station, consisting of two 3

, 58 7 MWt pressurized water reactors owned and operated by Exelon Corporation is located in Will County, Illinois. Unit No. 1 went critical on May 29, 1987. Unit No. 2 went critical on March 08, 1988. The site is located in northeastern Illinois, 15 miles south

-southwest of Joliet, Illinois, 60 miles southwest of Chicago and southwest of the Kankakee River.

This report covers those analyses performed by Teledyne Brown Engineering (TBE), Landauer Technologies and Environmental Inc. (Midwest Labs) on samples collected during the period January 1, 2014 through December 31, 2014.

A. Objective of the REMP The objectives of the REMP are to:

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

2. Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.

B. Implementation of the Objectives The implementation of the objectives is accomplished by:

1. Identifying significant exposure pathways.

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

3. Continuously monitoring those media before and during Station operation to assess Station radiological effects (if any) on man and the environment.

III. Program Description A. Sample Collection Samples for the Braidwood Station REMP were collected for Exelon Nuclear by Environmental Inc. (Midwest Labs). This section describes the general collection methods used by Environmental Inc. (Midwest Labs) to obtain environmental samples for the Braidwood Station REMP in 2014.

Sample locations and descriptions can be found in Table B

-1 and Figures B-1 through B

-3, Appendix B. The sampling methods used by Environmental Inc. are listed in Table B

-2. Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, public water, well water, fish, and sediment. Two gallon water samples were collected weekly from six surface water locations (BD

-10, BD-25 [control], BD

-38, BD-40, BD-55 and BD-56), and one weekly composite sample s of public drinking water at location (BD

-22) and ground/well water samples collected quarterly from eight locations (BD

-13, BD-34, BD-35, BD-36, BD-37, BD-50, BD-51 and BD-54). All samples were collected in new unused plastic bottles, which were rinsed with source water prior to collection. Fish samples comprising the flesh of largemouth bass, golden redhorse, shorthead redhorse , smallmouth bass , and common carp were collected semiannually at three locations, BD

-25 (control), BD

-28 and BD-41. Sediment samples composed of recently deposited substrate were collected at three locations semiannually, BD

-10, BD-25 (control), and BD-57. Atmospheric Environment

The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate and airborne iodine.

Air particulate samples were collected and analyzed weekly at eight locations (BD

-02, BD-03, BD-04, BD-05, BD-06, BD-19, BD-20 and BD-21). The control location was BD

-03. 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 filters and air iodine samples were replaced weekly and sent to the laboratory for analysis.

Terrestrial Environment

The terrestrial environment was evaluated by performing radiological analyses on milk and food product samples. Milk samples were collected biweekly at one location (BD

-17) from Ma y through October and monthly from November through April. Control location (BD

-18) was unavailable, due to cows being sold.

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 were collected annually in September at five locations (BD

-Control , BD-Quad 1, BD

-Quad 2, BD

-Quad 3 and BD-Quad 4). The control location was BD-Control. Various types of samples were collected and placed in new unused plastic bags and sent to the laboratory for analysis.

Ambient Gamma Radiation Beginning in 201 2, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP).

Optically Stimulated Luminescent Dosimeters (OSLD) were deployed and the use of Thermoluminescent Dosimeters (TLD) w as discontinued. This change may result in a step change in readings , up or down, depending on site characteristics. The relative comparison to control locations remains valid. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation

).

Each location consisted of 2 OSLD s. The OSLDs were exchanged quarterly and sent to Landauer for analysis. The OSLDs were placed at locations on and around the Braidwood Station site as follows:

An inner ring consisting of 16 locations (BD

-101, BD-102, BD-103, BD-104, BD-105, BD-106, BD-107, BD-108, BD-109, BD-110, BD-111a, BD-112, BD-113a, BD-114, BD-115 and BD

-116) at or near the site boundary.

An outer ring consisting of 16 locations (BD

-201, BD-202, BD-203, BD-204, BD-205, BD-206, BD-207, BD-208, BD-209, BD-210, BD-211, BD-212, BD-213, BD-214, BD-215 and BD-216) extending to approximately 5 miles from the site.

An additional (other) set consisting of seven locations (BD

-02, BD-04, BD-05, BD-06, BD-19, BD-20 and BD-21).

The balance of one location (BD

-03) represent s the control area.

The specific OSLD locations were determined by the following criteria:

1. The presence of relatively dense population;

2. Site meteorological data taking into account distance and elevation for each of the sixteen

-22 1/2 degree sectors around the site where estimated annual dose from Braidwood Station, if any , would be most significant.

B. Sample Analysis This section describes the general analytical methodologies used by TBE and Environmental Inc. (Midwest Labs) to analyze the environmental samples for radioactivity for the Braidwood Station REMP in 2014. The analytical procedures used by the laboratories are listed in Table B

-2.

In order to achieve the stated objectives, the current program includes the following analyses:

1. Concentrations of beta emitters in public and surface water and air particulates.

2. Concentrations of gamma emitters in public, ground/well and surface water, air particulates, milk, fish, sediment and food products.

3. Concentrations of tritium in public, ground/well and surface water.

4. Concentrations of I

-131 in air , mi lk and public water. 5. Concentrations of Ni

-63 in surface water, fish and sediment

. 6. Ambient gamma radiation levels at various site environs.

C. Data Interpretation The radiological and direct radiation data collected prior to Braidwood Station becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, Braidwood Station was considered operational at initial criticality. In addition, data was compared to previous years' operational data for consistency and trending. Several factors were important in the interpretation of the data:

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) was defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD was intended as a before the fact estimate of a system (including 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 Braidwood Station detection capabilities for environmental sample analysis.

The MDC is the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5% probability o f falsely concluding that a blank observation represents a "real" signal. The MDC is an a postori determination.

2. Net Activity Calculation and Reporting of Results Net activity for a sample was calculated by subtracting 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 resulting in a negative number. An MDC was reported in all cases where positive activity was not detected.

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

For surface, ground/well water

, and fish 12 nuclides, Mn

-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95 , I-131, Cs-134, Cs-137, Ba-140 a nd La-140 were reported.

For public water, sediment, air particulate, milk and vegetation 11 nuclides, Mn

-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, Cs-134, Cs-137, Ba-140 and La-140 were reported.

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

D. Program Exceptions For 20 1 4 the Braidwood Station REMP had a sample recovery rate in excess of 98.2%. Sample anomalies and missed samples are listed in the tables below:

BD-56 Each program exception was reviewed to understand the causes of the program exception. Sampling and maintenance issues were reviewed with the personnel involved to prevent recurrence. Occasional equipment breakdowns

, power outages and weather related issues were unavoidable.

The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation.

E. Program Changes There were no program changes in 2014.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water

Samples were taken weekly and composited monthly at six locations (BD

-10, BD-25 (control), BD-38, BD-40, BD-55 and BD-56). Of these locations

, only BD-10 could be affected by Braidwood Station's effluent releases as it is downstream of the NPDES permitted outfall. The following analyses were performed.

Gross Beta Samples from all locations were analyzed for concentrations of gross beta (Table C-I.1, Appendix C). Gross beta was detected in 66 of 69 samples. The values ranged from 2.

4 to 13.9 pCi/L. Concentrations detected were consistent with those detected in previous years (Figures C

-1 through C

-3, Appendix C).

Tritium Quarterly composites of weekly collections were analyzed for tritium activity (Table C

-I.2, Appendix C).

Tritium activity was detected in two samples. The values ranged from 2 21 to 2 41 pCi/l (Figures C

-4 through C

-6, Appendix C)

. Nickel-63 Monthly samples were analyzed for Nickel

-63 activity (Table C

-I.3, Appendix C).

Nickel-63 was not detected and the required LLD was met. Gamma Spectrometry

Samples from all locations were analyzed for gamma emitting nuclides (Table C

-I.4, Appendix C). No nuclides were detected and all required LLDs were met.

2. Public Water Monthly composite s of weekly samples were made at one location (BD-22). This location could be affected by Braidwood Station's effluent releases. The following analyses were performed:

Gross Beta Samples from the location were analyzed for concentrations of gross beta (Tables C

-II.1, Appendix C). Gross beta was detected in 11 of 12 samples. The values ranged from 2.7 to 4.5 pCi/L. Concentrations detected were consistent with those detected in previous years (Figure C

-7, Appendix C).

Tritium Monthly composites of weekly samples from BD

-2 2 were analyzed for tritium activity (Table C

-II.2, Appendix C). Tritium was detected in 11 of 12 samples. The concentration ranged from 2 23 to 1 , 410 pCi/L. Concentrations detected were consistent with those detected in previous years (Figure C

-8, Appendix C). Iodine Monthly composites of weekly samples from the location were analyzed for I

-131 (Table C-II.3, Appendix C). Iodine was not detected in any samples and the required LLD was met

. Gamma Spectrometry

Samples from the location were analyzed for gamma emitting nuclides (Table C

-II.4, Appendix C). No nuclides were detected and all required LLDs were met.

3. Ground/Well Water Quarterly samples were collected at eight locations (BD

-13, BD-34, BD-35, BD-36, BD-37, BD-50, BD-51and BD-54). The following analyses were performed:

Tritium Quarterly grab samples from the locations were analyzed for tritium activity (Table C

-III.1, Appendix C). Tritium was not detected in any sample and the required LLD was met.

(Figures C-9 through C-13, Appendix C)

. Gamma Spectrometry

Samples from all locations were analyzed for gamma emitting nuclides (Table C

-III.2, Appendix C). No nuclides were detected and all required LLDs were met.

4. Fish Fish samples comprised of largemouth bass, golden redhorse , shorthead redhorse , smallmouth bass, and common carp were collected at three locations (BD

-25, BD-28, and BD

-41) semiannually. Location BD

-28 could be affected by Braidwood Station's effluent releases. The following analysis was performed:

Gamma Spectrometry The edible portion of fish samples from all three locations was analyzed for gamma emitting nuclides (Table C

-IV.1, Appendix C). No fission or activation products were found. No nuclides were detected and all required LLDs were met.

5. Sediment Aquatic sediment samples were collected at three locations (BD-10, BD-25, and BD-57) semiannually. The locations at the Braidwood Station outfall to the Kanakakee River and downstream of the outfall, could be affected by Braidwood Station's effluent releases. The following analysis was performed:

Gamma Spectrometry Sediment samples from the location were analyzed for gamma emitting nuclides (Table C

-V.1, Appendix C).

Concentrations of the fission product Cs

-137 were found at location s BD-10 and BD-57. The concentration ranged from 1 0 4 to 1 62 pCi/kg dry. The activity detected was consistent with those detected in previous years (29 pCi/kg to 260 pCi/kg from 1995 to 2006). No other Braidwood fission or activation products were found and all required LLDs were met.

B. Atmospheric Environment

1. Airborne a. Air Particulates Continuous air particulate samples were collected from eight locations on a weekly basis. The eight locations were separated into three groups: Near field samplers (BD

-06, BD-19, BD-20 and BD-21), far field samplers within 10 km of the site (BD

-02, BD-04 and BD-05) and the Control sampler between 10 and 30 km from the site (BD

-03). The following analyses were performed:

Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table C

-VI.1 and C

-VI.2, Appendix C).

Detectable gross beta activity was observed at all locations. Comparison of results among the three groups aid in determining the effects, if any, resulting from the operation of Braidwood Station. The results from the near field (Group I) ranged from 8 E-03 to 32 E-02 pCi/m 3 with a mean of 1 8 E-02 pCi/m 3. The results from the far field (Group II) ranged from 8 E-03 t o 33 E-02 pCi/m 3 with a mean of 1 8 E-02 pCi/m 3. The results from the Control location (Group III) ranged from 8 E-03 to 49 E-02 pCi/m 3 with a mean of 1 9 E-02 pCi/m 3. Comparison of the 2014 air particulate data with previous years data indicate no effects from the operation of Braidwood Station. In addition a comparison of the weekly mean values for 2014 indicate no notable differences among the three groups (Figures C

-14 through C-18, Appendix C). Gamma Spectrometry

Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C

-VI.3, Appendix C). No nuclides were detected and all required LLDs were met.

b. Airborne Iodine Continuous air samples were collected from eight locations (BD-02, BD-03, BD-04, BD-05, BD-06, BD-19, BD-20 and BD-21) and analyzed weekly for I

-131 (Table C

-VII.1, Appendix C). All results were less than the minimum detectable concentration for I

-131. C. Terrestrial Environment

1. Milk Samples were collected from one location (BD-17) and are typically collected from the control location (BD

-18). Sampling frequencies were increased to biweekly in Ma y and continued through October and monthly sampling was performed November through April. The following analyses were performed:

Iodine-131 Milk samples from the indicator location were analyzed for concentrations of I

-131 (Table C

-VIII.1, Appendix C).

Iodine-131 was not detected in any sample s. All required LLDs were met.

Gamma Spectrometry Each milk sample was analyzed for concentrations of gamma emitting nuclides (Table C

-VIII.2, Appendix C). No nuclides were detected and all required LLDs were met. 2. Food Products Food product samples were collected at five locations (BD

-Control, BD

-Quad 1, BD

-Quad 2, BD

-Quad 3 and BD

-Quad 4) when available. Four locations, (located downwind, BD-Quad 1, BD

-Quad 2, BD

-Quad 3 and BD

-Quad 4) could be affected by Braidwood Station's effluent releases. The following analysis was performed:

Gamma Spectrometry

Samples from all locations were analyzed for gamma emitting nuclides (Table C

-IX.1, Appendix C). No nuclides were detected and all required LLDs were met. D. Ambient Gamma Radiation

Ambient gamma radiation levels were measured utilizing Optically Stimulated Luminescence Dosimeter (OSLD). Eighty Six OSLD locations were established around the site. Results of OSLD measurements are listed in Tables C

-X.1 to C-X.3, Appendix C.

Most OSLD measurements were below 3 0 mrem/quarter, with a range of 13.9 to 30.1 mrem/quarter. A comparison of the Inner Ring, Outer Ring and Other data to the Control Location data, indicate that the ambient gamma radiation levels from all locations were similar.

E. Land Use Survey

A Land Use Survey conducted during August 20 1 4 around the Braidwood Station was performed by Environmental Inc. (Midwest Labs) for Exelon Nuclear to comply with section 12.5.2 of the Braidwood Station's Offsite Dose Calculation Manual. The purpose of the survey was to document the nearest resident, milk producing animal and garden of greater than 500 ft 2 in each of the sixteen 22 1/2 degree sectors around the site. For dose calculation, a garden is assumed at the nearest residence. There were no changes required to the Braidwood Station REMP, as a result of this survey. The results of this survey are summarized below.

F. Errata Data

CY-BR-170-301, Offsite Dose Calculation Manual (ODCM), requires the AREOR to include the results of all radiological environmental samples and of all environmental radiation measurements taken during the period pursuant to the locations specified in the tables and figures in the ODCM.

1. A 2011 revision to the Braidwood ODCM added six Independent Spent Fuel Storage Installation (ISFSI) dosimeters to the Radiological Environmental Monitoring Program (REMP). The ISFSI dosimeters and the radiation dose recorded by the dosimeters were not included in the analyses reported in the 2011, 2012, and 2013 Annual Radiological Environmental Operating Reports (AREORs). Additionally, the land use census included in the AREOR does not identify the nearest resident to the ISFSI.

The ODCM also requires the nearest residence to the ISFSI be identified and reported in the land use census included in the AREOR.

Reporting omissions identified in the 2011, 2012, and 2013 AREORs:

Dosimeters for the ISFSI added to the ODCM in 2011 need to be included in the analyses documented in the following areas of the 2014 AREOR:

G. Summary of Results

- Inter-Laboratory Comparison Program

The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices (Appendix D). The PE samples supplied by Analytics Inc., Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP) were evaluated against the following pre

-set acceptance criteria:

1. Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of laboratory results and Analytics' known value. Since flag values are not assigned by Analytics, TBE

-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.

2. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, State Specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance 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 regulatory document.

3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.

The MAPEP defines three levels of performance: Acceptable (flag = "A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value. Performance is acceptable with warning when a mean result falls in the range from +/-

20% to +/- 30% of the reference value (i.e., 20% < bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.

In reviewing our environmental inter

-laboratory crosscheck programs, we identified 1) duplication of efforts on some matrices and isotopes and 2) that we are performing crosscheck samples on some matrices and isotopes that we do not perform for clients. Since the DOE MAPEP is designed to evaluate the ability of analytical facilities to correctly analyze for radiological constituents representative of those at DOE sites, the needed changes were made to the MAPEP program. Therefore, the following isotopes were removed from the MAPEP program:

Soil - gamma - will be provided by Analytics twice per year, starting in 2015. For 2014, one soil gamma is provided by MAPEP, the 2 nd soil gamma is provided by Analytics.

AP - gamma - is currently provided by Analytics.

Water - gamma, H-3, Sr-90, uranium, gross alpha and gross beta currently provided by ERA.

MAPEP evaluates non

-reported (NR) analyses as failed if they were reported in the previous series.

For the TBE laboratory, 16 3 out of 169 analyses performed met the specified acceptance criteria. Six analyses (Ni-63, K-40 and I-131 in water, and two Sr

-90s and one Gross Alpha in AP samples) did not meet the specified acceptance criteria for the following reason s: 1. Teledyne Brown Engineering's MAPEP March 2014 Ni

-63 in water result of 32.7 +/- 1.69 Bq/L was overlooked when reporting the data but would have passed the acceptance range of 23.9

- 44.2 Bq/L. NCR 14-04 2. Teledyne Brown Engineering's MAPEP March 2014 K

-40 in water result of 1.63 +/- 2.49 Bq/L was overlooked when reporting the data but would have passed the false positive test. NCR 14

-04

3. Teledyne Brown Engineering's ERA November 2014 I

-131 in water result of 15.8 pCi/L was lower than the known value of 20.3 pCi/L, failing below the lower acceptance limit of 16.8. The result was evaluated as failed with a found to known ratio of 0.778. No cause could be found for the slightly low result. All ERA I

-131 evaluations since 2004 have been acceptable. NCR 14

-08 4. Teledyne Brown Engineering's MAPEP March 2014 Sr

-90 in AP result of 0.822 Bq/sample was lower than the known value of 1.18 Bq/sample, failing below the lower acceptance limit of 0.83 Bq/sample. The rerun result was still low, but fell within the lower acceptance range of 0.836. The rerun result was statistically the same number as the original result. No cause could be found for the slightly low results. NCR 14

-04 5. Teledyne Brown Engineering's MAPEP September 2014 Sr-90 in AP result of 0.310 Bq/sample was lower than the known value of 0.703 Bq/sample. The gravimetric yield of 117% was very high (we normally see yields of 60% to 70 %) and could account for the low activity. NCR 14

-09 6. Teledyne Brown Engineering's MAPEP September 2014 Gr

-Alpha in AP result of 0.153 Bq/sample was lower than the known value of 0.53 Bq/sample. The AP sample was counted on the wrong side. The AP was flipped over and recounted with acceptable results.

NCR 14-09 For the EIML laboratory, 85 of 90 analy ses met the specified acceptance criteria.

Five analy ses (Water - Pu-238, Pu-239, Fe-55; AP - Co-57; Soil, Cs134) did not meet the specified acceptance criteria for the following reason s: 1. Environmental Inc., Midwest Laboratory's MAPEP February 201 4 water Pu-238 result of 1.28 Bq/L was higher than the known value of 0.83 Bq/L, exceeding the upper control limit of 1.08 Bq/L. The high bias on the plutonium was traced to contamination from a newly purchased standard. The result of the reanalysis with the new tracer was 0.68, which fell within the acceptance criteria.

2. Environmental Inc., Midwest Laboratory's MAPEP February 201 4 water Pu-239/240 result of 0.91 Bq/L was higher than the known value of 0.68 Bq/L, exceeding the upper control limit of 0.88 Bq/L. The high bias on the plutonium was traced to contamination from a newly purchased standard. The result of reanalysis with the new tracer was 0.66 Bq/L, which fell within the acceptance criteria.

3. Environmental Inc., Midwest Laboratory's MAPEP February 201 4 AP Co-57 result of 1.60 +/- 0.05 Bq/total sample failed the false positive test. Interference from the Eu

-152 resulted in the misidentification of Co

-57. 4. Environmental Inc., Midwest Laboratory's MAPEP February 2014 soil Cs-134 result of 6.10 +/- 1.80 Bq/kg failed the false positive test.

Long sample counting time lead to interference from naturally occurring Bi

-214 in the sample matrix with a close spectral energy. 5. Environmental Inc., Midwest Laboratory's MAPEP August 201 4 water Fe-55 result of 55.10 +/- 14.80 Bq/L was higher than the known value of 31.50 Bq/L, exceeding the upper control limit of 41.00 Bq/L. The result of the reanalysis of Fe

-55 was 32.63 +/- 16.30 Bq/L, which fell within the acceptance criteria.

The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

1 INTRODUCTION Braidwood Station, a two

-unit PWR station, is located in Will County, Illinois, fifteen (15) miles south

-southwest of Joliet, Illinois. Each reactor is designed to have a capacity of 3,587 thermal megawatts. Unit No. 1 went critical on May 29, 1987, and Unit No. 2 went critical on March 8, 1988. The station has been designed to keep releases to the environment at levels below those specified in the regulations.

Liquid effluents from Braidwood Station are released to the Kankakee River in controlled batches after radioassay of each batch. Gaseous effluents are released to the atmosphere and are calculated on the basis of analyses of grab samples of noble gases and tritium, as well as continuously collected composite samples of iodine and particulate activity sampled during the course of the year. The results of effluent analyses are summarized on a monthly basis. Airborne concentrations of noble gases, I

-131, and particulate radioactivity in offsite areas are calculated using effluent and meteorological data.

Carbon-14 concentration in offsite areas is calculated based on industry

-approved methodology for estimation of the amount released and meteorological data.

Environmental monitoring is conducted by sampling at indicator and control (background) locations in the vicinity of Braidwood Station to measure changes in radiation or radioactivity levels that may be attributable to station operations. If significant changes attributable to Braidwood Station are measured, these changes are correlated with effluent releases. An environmental monitoring program is conducted which also includes all potential pathways at the site. Gaseous pathways include ground plane (direct), inhalation, vegetation, meat, and milk.

Liquid pathways include potable water and freshwater fish. The critical pathway for 201 4 gaseous dose was vegetation. The critical pathway for 201 4 liquid dose was fresh water fish

.

SUMMARY

Calculations based on gaseous and liquid effluents, Kankakee River Flow and meteorological data indicate that public dose due to radioactive material attributable to Braidwood Station during the period does not exceed regulatory or Offsite Dose Calculation Manual (ODCM) limits.

The maximally exposed individual's total body dose due to gaseous and liquid emissions from licensed activities at Braidwood Station is 5.68E-01 mrem.

The assessment of radiation doses to the public is performed in accordance with the ODCM. The results of these analyses confirm that the station is operating in compliance with 10CFR50 Appendix I, 10CFR20 and 40CFR190.

3 1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere Measured concentrations of noble gases, radioiodine, and particulate radioactivity released to the atmosphere during the year, are listed in Table 1.1-1.

A total of 3.42E-01 curies of fission and activation gases were released with a maximum quarterly average release rate of

1.81E-02 µCi/sec for Unit 1 and 1.59E-02 µCi/sec for Unit 2. A total of 2.7 3E-04 curies of radioiodine were released during the year with a maximum average quarterly release rate of 1.04E-05 µCi/sec for Unit 1 and 2.10E-05 µCi/sec for Unit 2.

A total of 1.15E-04 curies of beta-gamma emitters were released as airborne particulate matter with a maximum average release rate of <LLD µCi/sec for Unit 1 and 2.10E-05 µCi/sec for Unit 2. Alpha-emitting radionuclides were below the lower limit of detection (LLD) for the year.

A total of 2.7 1E+0 2 curies of tritium were released with a maximum average quarterly release rate of 3.70E+00 µCi/sec for Unit 1 and 7.79E+00 µCi/sec for Unit 2.

A total of 8.61E+00 curies of C

-14 was released with a maximum average quarterly release rate of 1.41E-01 uCi/sec from Unit 1 and 1.41E-01 uCi/sec from Unit 2. 1.2 Liquids Released to Kankakee River A total of 7.42E+06 liters of radioactive liquid wastes (prior to dilution) containing 9.48E-02 curies (excluding tritium, noble gases and alpha) were discharged from the station. These wastes were released at a maximum quarterly diluted average concentration of 1.29E-08 µCi/ml. Alpha-emitting radionuclides were less than the LLD for the year. A total of 3.00E+03 curies of tritium were released from the station. Quarterly release activities are given in Table 1.2

-1. 2.0 SOLID RADIOACTIVE WASTE Solid radioactive wastes were shipped by truck to the Envirocare of Utah and Waste Control Specialists disposal facilities and various waste processors. For detail s, refer to the Braidwood Station 201 4 Radioactive Effluent 4 Release Report.

3.0 DOSE TO MAN

3.1 Gaseous

Effluent Pathways Table 3.1-1 summarizes the doses resulting from releases of airborne radioactivity via the different exposure pathways.

3.1.1 Noble

Gases 3.1.1.1 Gamma Dose Rates Offsite Gamma air and total body dose rates are shown in Table 3

.1-1 and were calculated based on measured effluents and average meteorological data. Based on measured effluents and average meteorological data, the maximum total body dose to an individual would be 5.25E-01 mrem for the year (Table 3.1

-1) with an occupancy or shielding factor of 0.7 used. The maximum total body dose based on measured effluents and concurrent meteorological data would be 5.39E-01 mrem (Table 3.4

-1). The maximum gamma air dose was 7.01E-06 mrad (Table 3.1

-1) based on measured effluents and average meteorological data and 1.17E-05 mrad based on concurrent meteorological date (Table 3.4-1). 3.1.1.2 Beta Air and Skin Dose Rates The range of beta particles in air is relatively small (on the order of a few meters or less); consequently, plumes of gaseous effluents may be considered "infinite" for purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive skin tissues is difficult to calculate due to the effect of the beta particle energies, thickness of inert skin and clothing covering sensitive tissues. For purposes of this report the skin is taken to have a thickness of 7.0 mg/cm 2 and an occupancy factor of 1.0 is used. The skin dose from beta and gamma radiation for the year was 1.71E-05 mrem based on concurrent meteorological data (Table 3.4

-1).

5 The maximum offsite beta air dose for the year was 1.66E-05 mrad (Table 3.1

-1) based on measured effluents and average meteorological data and 1.71 E-05 mrad based on concurrent meteorological data (Table 3.4

-1). 3.1.2 Radioactive Iodine

& Particulate The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. I

-131 released during routine operation of the station may be made available to man resulting in a dose to the thyroid. C

-14 is also included in this category. C

-14 exhibits a capacity to concentrate in bone.

C-14 is released in gaseous form and is absorbed into vegetation through photosynthesis. The principal pathway s of interest for C-14 are the consumption of vegetation by humans and milk from which animals have ingested C

-14 through the consumption of vegetation. With the inclusion of C-14 i n plant effluent calculations, human dose in this category is primarily driven by the release of C

-14 from the plant.

The hypothetical dose to the maximum exposed individual living near the station via ingestion of milk and vegetation was calculated. The source of milk and vegetation was assumed to be at the nearest site boundary with the cows pastured and vegetation grown from May through October. The maximum dose from radioactive iodine and particulate (including C

-14) to any organ was 2.3 1E+00 mrem (child/bone) based on measured effluents and average meteorological data and 2.40E+00 mrem based on concurrent meteorological data. The maximum dose from radioactive iodine and particulate (including C

-14) to the whole body was 5.25E-01 mrem (child) based on measured effluents and average meteorological data and 5.39E-01 mrem based on concurrent meteorological data.

3.2 Liquid

Effluent Pathways The three principal pathways through the aquatic environment for potential doses to man from liquid waste are ingestion of potable water, eating aquatic foods, and exposure while on the shoreline. Not all of these pathways are significant or applicable at a given time or station but a reasonable approximation of the dose can be made by adjusting the dose formula for season of the year or type and degree of use of the aquatic environment. NRC developed equations* were 6 used to calculate the doses to the whole body, lower GI tracts, thyroid, bone and skin; specific parameters for use in the equations are given in the Braidwood Offsite Dose Calculation Manual. The maximum whole body dose and any organ dose for the year was 4.26E-02 mrem and 8.60E-02 mrem, respectively (Table 3.2

-1 [adult]). 3.3 Assessment of Dose to Member of Public During the period January to December, 201 4 , Braidwood Station did not exceed the following limits as shown in Table 3.1

-1 and Table 3.2-1 (based on annual average meteorological data), Table 3.4-1 (based on concurrent meteorological data), and Table 3.3-1: The RETS limits on dose or dose commitment to an individual due to radioactive materials in liquid effluents from each reactor unit (1.5 mrem to the whole body or 5 mrem to any organ during any calendar year; 3 mrem to the whole body or 10 mrem to any organ during the calendar year).

The RETS limits on air dose in noble gases released in gaseous effluents to a member of the public from each reactor unit (5 mrads for gamma radiation or 10 mrad for beta radiation during any calendar quarter; 10 mrad for gamma radiation or 20 mrad for beta radiation during a calendar year).

The RETS limits on dose to a member of the public due to iodine-131, iodine

-133, tritium, and radionuclides in particulate form with half

-lives greater than eight days in gaseous effluents released from each reactor unit (7.5 mrem to any organ during any calendar quarter; 15 mrem to any organ during any calendar year).

The 10CFR20 limit on Total Effective Dose Equivalent to individual members of the public (100 mrem) during any calendar year.

4.0 SITE METEOROLOGY A summary of the site meteorological measurements taken during each calendar quarter of the year is given in Appendix F. The data are presented as cumulative joint frequency distributions of the wind direction for the 203' level and wind speed class by atmospheric stability class determined from the temperature difference between the 199' and 30' levels. Data recovery for these measurements was 99.8% during 201 4.

I. Summary and Conclusions In 2014, Exelon continued a comprehensive program that evaluates the impact of station operations on groundwater and surface water in the vicinity of Braidwood Station. This evaluation involved numerous station personnel and contractor support personnel. This report covers groundwater and surface water samples collected from the environment, both on and off station property

, in 2014. During that time period , 751 analyses were performed on 2 75 samples from 72 locations.

In assessing all the data gathered for this report, it was concluded that the operation of Braidwood Station had no adverse radiological impact on the environment.

Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) as specified in the Offsite Dose Calculation Manual (ODCM) in any of the groundwater or surface water samples. In the case of tritium, Exelon specified that its laboratories achieve a lower limit of detection 10 times less than Braidwood's ODCM and 100 times less than federal regulation.

Strontium-89/90 was not detected at a concentration greater than the LLD of 10.0 and 1.0 picoCuries per liter (pCi/L) respectively in any of the groundwater samples tested.

No tritium was detected in the groundwater or surface water samples at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission Reporting Limit) of 20,000 pCi/L. Low levels of tritium were detected in groundwater and surface water at concentrations greater than the LLD of 200 pCi/L in 73 of 2 67 analyses. The tritium concentrations ranged from 164 +/- 1 0 1 pCi/L to 4 , 02 0 +/- 453 pCi/L. The tritium that was detected in the groundwater or surface water is believed to be the result of isolated historical releases and/or background from external sources greater than 200 pCi/L.

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater and surface water samples throughout the sampling year in 2014. Gross Alpha (dissolved) was detected in t wo groundwater and surface water samples. The concentrations ranged from 0.

9 to 21.3 pCi/L. Gross Alpha (suspended) was detected in two groundwater samples. The concentrations ranged from 2.8 to 4.0 pCi/L. Gross Beta (dissolved) was detected in 53 groundwater and surface water samples. The concentrations ranged from 1.0 to 49.3 pCi/L. Gross Beta (suspended) was detected in three groundwater samples

. The concentrations ranged from 2.5 to 7.2 pCi/L. Hard-To-Detect , or difficult to measure nuclides , were not sampled or analyzed in 2014.

II. Introduction Braidwood Station, a two

-unit PWR station is located in Will County, Illinois, fifteen (15) miles south

-southwest of Joliet, Illinois. Each reactor is designed to have a capacity of 3, 587 thermal megawatts. Units No. 1 went critical on May 29, 1987 and Unit No. 2 went critical on March 8, 1988. The station has been designed to keep releases to the environment at levels below those specified in the regulations.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. Midwest Labs (EIML) on samples collected in

2014.

A. Objective of the Radiological Groundwater Protection Program (RGPP) The long-term objectives of the RGPP are as follows:

1. Identify suitable locations to monitor and evaluate potential impacts from station operations to preclude radiological impact to the environment and potential drinking water sources.

2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up

-to-date knowledge of flow patterns on the surface and shallow subsurface.

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

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

. 5. Regularly assess analytical results to identify adverse trends.

6. Take necessary corrective actions to protect groundwater resources

. B. Implementation of the Objectives The objectives identified have been implemented at Braidwood Station as discussed below:

1. Exelon identified locations to monitor and evaluate d potential impacts from station operations.

2. The Braidwood Station reports describe the local hydrogeologic regime. Periodically, the flow patterns on the surface and shallow subsurface are updated based on ongoing measurements.

3. Braidwood Station will continue to perform routine sampling and radiological analysis of water from selected locations.

4. Braidwood Station has implemented procedures to identify and report new leaks, spills, or other detections with potential radiological significance in a timely manner.

5. Braidwood Station staff and consulting hydrogeologist assess analytical results on an ongoing basis to identify adverse trends.

C. Program Description

1. Sample Collection Sample locations can be found in Table A-1 and Figures A

-1 through A-3, Appendix A.

Groundwater and Surface Water Samples of groundwater and surface water are collected, managed, transported and analyzed in accordance with EPA methods. Sample locations, sample collection frequencies and analytical frequencies are managed in accordance with approved station procedures. Contractor and/or station personnel are trained in the collection, preservation management and shipment of samples as well as in documentation of sampling events. Analytical laboratories are subject to internal quality assurance programs, industry cross

-check programs as well as nuclear industry audits. Station personnel review and evaluate all analytical data as it is received. Additionally, analytical data results are reviewed by an independent hydrogeologist for adverse trends or changes to hydrogeologic conditions.

D. Characteristics of Tritium (H

-3) Tritium is a radioactive isotope of hydrogen. Its chemical properties are the same as hydrog en. Tritiated water behaves the same as ordinary water in both the environment and the body. Tritiated water can be taken into the body by drinking water, breathing air, eating food or absorption through the skin. Once tritiated water enters the body, it disperses quickly and is uniformly distributed. Tritiated water is excreted primarily through urine with a clearance rate characterized by an effective biological half

-life of about 14 days. With such a short biological half

-life, an acute ingestion would be cleared rapidly.

Organically bound tritium (tritium that i s incorporated into carbon containing compounds) can remain in the body for a longer period.

Tritium is produced naturally in the upper atmosphere when cosmic rays interact with air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity and in special production reactors

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

III. Program Description A. Sample Analysis This section describes the general analytical methodologies used by Teledyne Brown Engineering (TBE) and Environmental Incorporated Midwest Laboratory (EIML) to analyze the environmental samples for radioactivity for the Braidwood Station RGPP in 2014.

In order to achieve the stated objectives, the current program includes the following analyses:

1. Concentrations of gamma emitters in groundwater and surface water. 2. Concentrations of strontium in groundwater and surface water.

3. Concentrations of tritium in groundwater and surface water.

4. Concentrations of Gross Alpha and Gross Beta (Dissolved and Suspended) in groundwater and surface water. 5. Concentrations of Am

-241 in groundwater.

6. Concentrations of Cm

-242 and Cm

-243/244 in groundwater.

7. Concentrations of Pu

-238 and P u-239/240 in groundwater.

8. Concentrations of U

-234, U-23 5 and U-238 in groundwater.

9. Concentrations of Fe

-55 in groundwater.

10. Concentrations of Ni

-63 in groundwater.

B. Data Interpretation The radiological data collected prior to Braidwood Station becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, Braidwood Station was considered operational at initial criticality. Several factors were important in the interpretation of the data:

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is specified by federal regulation as a minimum sensitivity value that must be achieved routinely by the analytical parameter.

2. Laboratory Measurements Uncertainty The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the measurement 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 (+/-) the estimated sample standard deviation, as TPU, that is obtained by propagating all sources of analytical uncertainty in measurements.

Analytical uncertainties are reported at the 95% confidence level in this report for reporting consistency with the AREOR.

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

For groundwater and surface water 14 nuclides, Be

-7, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, I-131, Cs-134, Cs-137, Ba-140 and La

-140 were reported.

C. Background Analysis

A pre-operational radiological environmental monitoring program (pre-operational REMP) was conducted to establish background radioactivity levels prior to operation of the Station. The environmental media sampled and analyzed during the pre

-operational REMP were atmospheric radiation, fall

-out, domestic water, surface water, marine life

and foodstuffs. The results of the monitoring were detailed in the report entitled, Environmental Radiological Monitoring for Braidwood Nuclear Power Station Commonwealth Edison Company, Annual Report 1986, May 1987. 1. Background Concentrations of Tritium The purpose of the following discussion is to summarize background measurements of tritium in various media performed by others. a. Tritium Production Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man

-made) sources. In the upper atmosphere, "Cosmogenic" tritium is produced from the

bombardment of stable nuclides and combines with oxygen to form tritiated water, which will then enter the hydrologic cycle. Below ground, "lithogenic" tritium is produced by the bombardment of 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 tritium is introduced directly to groundwater.

A major anthropogenic source of tritium and strontium

-90 comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased significantly during the 1950s and early 1960s and later with additional testing, resulting in the release of significant amounts of tritium to the atmosphere. 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

Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides. Two publicly available databases that provide tritium concentrations in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet database. GNIP provides tritium precipitation concentration data for samples collected world wide from 1960 to 2014.

RadNet provides tritium precipitation concentration data for samples collected at stations through out the U.S. from 1960 up to and including 2014. 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 testing of thermonuclear weapons. Tritium concentrations in surface water showed a sharp decline up until 1975 followed by a gradual decline since that time. Tritium concentrations in Midwest precipitation have typically been below 100 pCi/L since around 1980. Tritium concentrations in wells may still be above the 200 pCi/L detection limit from the external causes described 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 in tritium.

c. Surface Water Data Tritium concentrations are routinely measured in large surface water bodies, including Lake Michigan and the Mississippi River. Illinois surface water data were typically less than 100 pCi/L.

The USEPA RadNet surface water data typically has a reported 'Combined Standard Uncertainty' of 35 to 50 pCi/L.

According to USEPA, this corresponds to a

+/- 70 to 100 pCi/L 95% confidence bound on each given measurement. Therefore, the typical background data provided may be subject to measurement uncertainty of approximately

+/- 70 to 100 pCi/L.

The radio-analytical laboratory is counting tritium results to an Exelon specified LLD of 200 pCi/L. Typically, the lowest positive measurement will be reported within a range of 40

- 240 pCi/L or 140 +/- 100 pCi/L. Clearly, these sample results cannot be distinguished as different from background at this concentration.

IV. Results and Discussion

A. Missed Sample

Exelon maintains a RGPP as part of the nuclear industry's voluntary groundwater protection initiative as described in NEI 07-07. As part of this program, samples are obtained routinely from monitoring wells and surface waters at Braidwood based on the frequencies outlined in station procedures.

According to the Station RGPP, the following remediation wells were not sampled in 2014; BL

-11, MW-11, MW-2, MW-4, MW-7, MW-BW-201S, MW-BW-202S, MW-BW-203S, VB-10-1, MW-134D, MW-BW-130D, MW-BW-141D, MW-BW-142D, MW-BW-143D, MW-BW-207I, 0WM31P, RW-10, RW-5, RW-6, RW-7, and RW-9. Additionally one surface water sample was missed in 2014; Ditch (DS

-2). The Station RGPP requires the wells designated as detection wells to be sampled and analyzed for tritium on a quarterly basis. The aforementioned locations were not sampled during one or more of the quarters in 2014. Reasons for lack of sampling include well condition deficiencies, low well production, frozen water preventing sampling an d

remediation pumps not working.

The Station RGPP also requires designated detection wells be analyzed for gamma

-radionuclides, gross

-alpha and beta, and strontium 89/90 on an annual basis. Remediation well

RW-9 did not have these analyses performed during 2014. The sample was not able to be obtained because RW

-9 was not operating.

B. Groundwater Results Groundwater

Samples were collected from on and off

-site wells throughout the year in accordance with the Station radiological groundwater protection program. Analytical results and anomalies are discussed below.

Tritium Samples from all locations were analyzed for tritium activity.

Tritium values ranged from the lower detection limit to 4 , 02 0 pCi/l These wells are located onsite and are not available as a drinking water sour ce. Some contamination still exists and monitoring is ongoing (Table B-I.1, Appendix B)

.

Strontium Strontium-89 and Strontium

-90 were analyzed for in 63 sample s. Strontium-89 was less than the required detection limit of 10.0 pCi/liter. Strontium

-90 was less than the required detection limit of 1.0 pCi/liter (Table B-I.1, Appendix B).

Gross Alpha and Beta (dissolved and suspended)

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater and surface water samples throughout the sampling year in 2014. Gross Alpha (dissolved) was detected in two groundwater and surface water samples. The concentrations ranged from 0.

9 to 21.3 pCi/L.

Gross Alpha (suspended) was detected in two groundwater samples

. The concentrations ranged from 2.8 to 4.0 pCi/L.

Gross Beta (dissolved) was detected in 53 groundwater and surface water samples. The concentrations ranged from 1.0 to 49.3 pCi/L. Gross Beta (suspended) was detected in three groundwater samples

. The concentrations ranged from 2.5 to 7.2 pCi/L.

Gross alpha and gross beta are routinely seen in environmental samples and are not necessarily attributable to Station's effluents (Table B-I.1, Appendix B). Hard-To-Detect Hard-To-Detect analyses were not performed in 2014 (Table B-I.3, Appendix B)

. Gamma Emitters

Naturally occurring K-40 was detected in two samples. The concentrations ranged from 64 to 1 85 pCi/L. No other gamma emitting nuclides were detected in any of the samples analyzed. (Table B-I.2 , Appendix B)

C. Surface Water Results

Surface Water

Samples were collected from three surface water locations throughout the year in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.

Tritium Samples from all locations were analyzed for tritium activity (Table

B-II.1, Appendix B). Tritium values ranged from the minimum detection limit to 255 pCi/l. Strontium Strontium-89 and Strontium

-90 were analyzed for in two samples. Strontium-89 was less than the required detection limit of 10.0 pCi/liter. Strontium

-90 was less than the required detection limit of 1.0 pCi/liter (Table B

-II.1, Appendix B).

Gamma Emitters

No gamma emitting nuclides were detected in any of the samples analyzed (Table B-I I.2, Appendix B)

. D. Drinking Water Well Survey

Requested drinking water wells near Braidwood Station were sampled on a quarterly basis in 2014. E. Summary of Results - Inter-Laboratory Comparison Program

Inter-Laboratory Comparison Program results for TBE are presented in the AREOR.

F. Leaks, Spills, and Releases

There are no new previously unidentified leaks or plumes at Braidwood Station. G. Trends and Analyses

Monitoring of remediation activities indicate that tritium concentrations in affected areas have remained relatively unchanged since 2010. Tritium has been routinely detected in samples from remediation well RW-6 since 2008, however sampling results from the 3 rd and 4 th quarter of 2014 show a significant increase over the 2 nd quarter 2014 results when tritium concentration measurements were less than LLD.

Tritium concentrations measured in RW

-6 are likely due to the migration of a known plume, caused by identified historic spills and leaks at the Station.

H. Investigations There were no investigations that took place in 2014 as a result of groundwater sample result. Location RW

-6 will continue to be monitored to evaluate whether the elevated results in the 3 rd and 4 th quarter of 2014 were due to the migration of a former plume or if there is a potential release from the blowdown line.

I. Actions Taken

1. Compensatory Actions

No compensatory actions were initiated in 2014.

2. Installation of Monitoring Wells No new monitoring wells were installed in 2014.

3. Actions to Recover/Reverse Plumes No actions were undertaken to recover/reverse plumes in 2014.
