I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for*

the Dresden Nuclear Power Station (DNPS) of Exelon covers the period 1 January 2016 through 31 December 2016. During that time period 2,044 analyses were performed on 1,909 samples. In assessing all the data gathered for this report it was concluded that the operation of DNPS had no adverse radiological impact on the environment.

In 2016, the Dresden Generating Station released to the environment through the radioactive effluent liquid and gaseous pathways approximately 6.35E+01 curies of fission and activation gasses, 2.93E+01 curies of Carbon-14 (C-14) and approximately 6.88E+OO curies of tritium. The dose from both liquid and gaseous effluents was conservatively calculated for the Maximum Exposed Member of the Public. The* results of those calculations and their comparison to the allowable limits are excerpted from the Dresden Generating Station 2016 Annual Radioactive Effluent Release Report (Radiological Impact on Man, starting at page 79):

Regulatory annual gaseous dose limits are listed on page 1 section 1.a. and section 1.b.c., of the 2016 Annual Radioactive Effluent Release Report as well as in Dresden ODCM. The above annual gaseous dose values are well below any regulatory limits.

3. Doses to a Member of the Public due to Direct Radiation in 2016 (from 01/01/2016 to 12/31/2016):

These numbers are calculated .*per ODCM methodologies, and are used to demonstrate compliance with 40CFR190 total dose limit requirements listed on page 1 section 1.e, of the 2016 Annual Radioactive Effluent Release Report as well as in Dresden ODCM.

4. Total body doses to the population and average doses to individuals in the population from all receiving-water-related-pathways are not applicable to Dresden Station. No downstream drinking water pathway exist within the specified distance of 10 kilometers (6.2 miles).

5. Total body doses to the population and average doses to individuals in the population from gaseous effluents to a distance of 50 miles from the site are not applicable to Dresden Station.

' 6. Doses from liquid and gaseous effluent to members of the public due to their activities inside the site boundary for the report period are not applicable to Dresden Station. Any member of the public who is onsite for a significant period of time is issued an Optical Stimulated Luminescent Dosimeter (OSLO) to monitor direct radiation exposure.

7. Liquid and Gaseous Effluent Radiation Monitors and Instrumentation Unavailability for the Period Beyond the Requirements of the ODCM, Including Sampling Deviation: For the report period, there was one radiation monitor that exceeded its ODCM allowed inoperability time of 30 days. The Unit 2 Service Water rad monitor was non-functional for 31 days from 4/6/16 to 5/7/16. Issue Report 2667212 was written to describe the event and to track corrective actions. Compensatory sampling was in place from the time the monitor was considered non-functional until it was returned to functional status. The rad monitor was initially declared non-functional due to repeated failure and multiple replacements of the of the pump/motor/gearbox combination. Troubleshooting activities were performed throughout the ODCM allowed inoperability time, as a team of individuals determined potential causes of the pump problems, and then worked to systematically determine the actual cause. It was determined that the seal purge line was plugged, which lead to a successful pump replacement and pump run. The U2 Service Water rad monitor was restored to functional status on 5/7/16.

8. 40 CFR 190 / 10 CFR 72 Compliance:

The General Electric Hitachi Nuclear Energy Morris Operation (GEH Morris Operation) facility is physically located near Dresden Station, hence it is considered in the evaluation of the uranium fuel cycle on members of the public in the general environment.

Dresden decommissioning activities (Unit 1) and operations (Units 2 and 3) resulted in a maximum 9.34E-02 mrem organ dose and

8. 79E+OO mrem total body dose. The Radiological Environmental Monitoring Program (REMP) direct radiation monitoring at or near the site boundary demonstrates that total body *dose calculations to account for skyshine as found in the ODCM are conservative.

No effluents were released from the Dresden Independent Spent Fuel Storage Installations (ISFSls) during 2016. REMP direct radiation monitoring at or near the site boundary demonstrates that the ISFSls do not result in measurable dose to the public.

According to the 2016 GEH Morris Operation 10 CFR 72.44(d)(3) report, dated 2/24/2017, for the 2016 calendar year, the maximum dose at their site boundary from direct radiation exposure was 4.1 OE-01 mrem. The maximum organ dose from site activities was 1.20E-07 mrem for 2016.

Maximum combined total body dose from Dresden Station and GEH Morris Operation activities was 9.20E+OO mrem during 2016, which was 36.80 % of the 40 CFR 190 limit of 25 mrem.

Maximum combined organ dose from Dresden and GEH Morris Operation activities was 9.34E-02 mrem during 2016. This was 0.37 % of the 40 CFR 190 limit of 25 mrem to any organ. The combined thyroid dose was 2.63E-02 mrem. This was 0.04 % of the 40 CFR 190 limit of 75 mrem.

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

Fish (commercially and recreationally important species), and sediment samples were analyzed for concentrations of gamma-emitting nuclides. No fission or activation products were detected in fish. Cesium-137 was detected in both sediment samples in 2016 .at levels slightly higher than the level of detection.

4

Air particulate samples were analyzed for concentrations of gross beta and gamma-emitting nuclides. Gross beta results at the indicator locations were consistent with those at the control location. No fission or activation products were detected.

High sensitivity lodine-131 (1-131) analyses were performed on weekly air samples. All results were less than the minimum detectable activity for 1-131.

Cow milk samples were analyzed for concentrations of 1-131 and gamma-emitting nuclides. All 1-131 results were Jess -than the minimum detectable activity. No fission or activation products were detected. Food product samples were analyzed for concentrations of gamma-emitting nuclides. No fission or activation products were detected.

Environmental gamma radiation measurements were performed quarterly using Optically Stimulated Luminescent Dosimetry (OSLO). The relative comparison to control locations remains valid.

II. Introduction The Dresden Nuclear Power Station (DNPS), consisting of one retired reactor and two operating boiling water reactors owned and operated by Exelon Corporation, is located in Grundy County, Illinois. Unit No. 1 went critical in 1960 and was retired in 1978. Unit No. 2 went critical on 16 June 1970. Unit No. 3 went critical on 02 November 1971. The site is located in northern Illinois, approximately 12 miles southwest of Joliet, Illinois at the confluence of the Des Plaines and Kankakee Rivers where they form the Illinois River.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Landauer on samples collected during the period 1 January 2016 through 31 December 2016.

An assessment of the station's radioactive effluent monitoring results and radiation dose via the principle pathways of exposure resulting from plant emissions of radioactivity including the maximum noble gas gamma and beta air doses in the unrestricted area, an annual summary of meteorological conditions including wind speed, wind direction and atmospheric stability and the result of the 40CFR 190 uranium fuel cycle dose analysis for the calendar year are published in the station's Annual Radioactive Effluent Release Report.

A. Objective of the Radiological Environmental Monitoring Program (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; 6

Ill. Program Description A. Sample Collection Samples for the DNPS REMP were collected for Exelon Nuclear by Environmental Incorporated Midwest Laboratory (EIML). This section describes the general collection methods used by EIML to obtain environmental samples for the DNPS REMP in 2016. Sample locations and descriptions can be found in Appendix B, Table B-1 and Figures B-1 and B-2. The collection methods used by EIML are listed in Table B-2.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water (SW), ground water (GW), fish (Fl) and sediment (SS). Samples were collected from three surface water locations (D-21, D-52 and D-57) and composited for analysis. Control locations were D-52 and D-57. Samples were collected quarterly or more

frequently from two well water locations (D-23 and D-35). All samples

were collected in new unused plastic bottles, which were rinsed with source water prior to collection. Fish samples comprising the flesh of freshwater drum, largemouth bass, common carp, channel catfish, and golden redhorse were collected semiannually at two locations, D-28 and D-46 (Control). Sediment samples composed of recently deposited substrate were collected at one location semiannually, D-27.

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

Airborne iodine and particulate samples were collected at fourteen locations (D-01, D-02, D-03, D-04, D-07, D-08, D-10, D-12, D-14, D-45, D-53,* D-55, D-56 and D-58). The control location was D-12. Airborne iodine and particulate samples were obtained at each location using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The air filters and air iodine samples were replaced weekly and sent to the laboratory for analysis.

Terrestrial Environment Milk (M) samples are typically collected biweekly at one control location (D-25) from May through October and monthly from November through April. Other than D-25, there are no additional milking animals within 10 km (6.2 miles) of the site. All milk samples from D-25 were collected in 7

new unused two gallon plastic bottles from the bulk tank, preserved with sodium bisulfite and shipped promptly to the laboratory. Food products (FL) were collected annually in August at five locations (0-Control, 0-Quad 1, 0-Quad 2, 0-Quad 3 and o:.Quad4). The control location was 0-Control. Various types of samples were collected and placed in new unused plastic bags and sent to the laboratory for analysis.

Ambient Gamma Radiation Each location consisted of two OSLO sets. The OSLO locations were placed on and around the ONPS site as follows:

An inner ring consisting of 17 locations (0-58, 0-101, 0-102, 0-103, 0-104, 0~105, 0-106, 0-107, 0-108, 0-109, 0-110, 0-111, 0-112a, 0-113, 0-114, 0-115 and 0-116) at or near the site boundary.

An outer ring consisting of 16 locations (0-201, 0-202, 0-203, 0-204, 0-205, 0-206, 0-207, 0-208, 0-209, 0-210, 0-211, 0-212, 0-213, 0-214, 0-215 and 0-216) approximately 5 to 10 km (3.1 to 6.2 miles) from the site.

Other locations consisting of OSLO sets at the 13 air sampler locations (0-01, 0-02, 0-03, 0-04, 0-07, 0-08, 0-10, 0-14, 0-45, 0-53, 0-55, 0-56 and 0-58).

The balance of one location (0-12) represents the control area OSLO set.

The OSLOs were exchanged quarterly and sent to Landauer for analysis.

B. Sample Analysis This section describes the general analytical methodologies used by TBE and EIML to analyze the environmental samples for radioactivity for the ONPS REMP in 2016. The analytical procedures used by the laboratories are listed in Appendix B Table 8-2.

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

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

2. Concentrations of gamma emitters in ground and surface water, air particulates, milk, fish, sediment and vegetation 8

3. Concentrations of tritium in ground and surface water

4. Concentrations of 1-131 in air and milk

5. Ambient gamma radiation levels at various site environs C. Data Interpretation For the purpose of this report, Dresden Nuclear Power Station was considered operational at initial criticality. In addition, data were 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 DNPS detection capabilities for environmental sample analysis.

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

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 effecting 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 groundwater, surface water, and vegetation twelve nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, 1-131, Cs-134, Cs-137, Ba-140 and La-140 were reported.

For fish, sediment, air particulate and milk eleven nuclides, 9

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 single analysis uncertainty.

D. Program Exceptions For 2016 the DNPS REMP had a sample recovery rate of approximately 99%. Sample anomalies and missed samples are listed in the tables below:

E. Program Changes There were no program changes in 2016.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were composited or taken weekly and composited for analysis at three locations (D-21, D-52 and D-57). Of these locations only D-21, located downstream, could be affected by

Dresden's effluent releases. The following analyses were performed:

Gross Beta Monthly composites from all locations were analyzed for concentrations of gross beta (Table C~l.1, Appendix C). Gross Beta was detected in 36 of 36 samples. The values ranged from 12

3.1 to 12.1 pCi/I. Concentrations detected were consistent with those detected in previous years (Figures C-1, C-2 and C-3, Appendix C).

Tritium Quarterly composites from all locations were analyzed for tritium activity (Table C-1.2, Appendix C). Three samples at indicator station D-21 were positive for tritium at concentrations ranging from 282 to 666 pCi/L. Four samples at control station D-57 were positive for tritium. The values ranged from 242 to 1,270 pCi/L.

Concentrations detected were consistent with those detected in previous years (Figures C-4, C-5 and C-6, Appendix C).

Gamma Spectrometry Monthly composites from all locations were analyzed for gamma-emitting nuclides (Table C-1.3, Appendix C). No nuclides were detected and all required LLDs were met.

2~ Ground Water Quarterly or more frequent grab samples were collected at two locations (D-23 and D-35). These locations could be affected by Dresden's effluent releases and by sources upstream on the Kankakee River. The following analyses were performed:

Tritium All samples were analyzed for tritium activity (Table C-11.1, Appendix C). Tritium was detected in 12 of 16 samples. The concentrations ranged from 354 to 636 pCi/I. Concentrations detected were consistent with those detected in previous years (Figure C-7, Appendix C).

Gamma Spectrometry All samples were analyzed for gamma-emitting nuclides (Table C-11.2, Appendix C). No nuclides were detected and all required LLDs were met.

3. Fish Fish samples comprised of common carp, freshwater drum, largemouth bass, channel catfish, and golden redhorse were 13

collected at two locations (D-28 and D-46) semiannually. Location D-28 could be affected by Dresden's effluent releases. The following analysis was performed:

Gamma Spectrometry The edible portion of fish samples from both locations was analyzed for gamma-emitting nuclides (Table C-111.1, Appendix C).

Only naturally-occurring nuclides (not shown on the tables) were found at both locations. No fission or activation products were detected.

4. Sediment Aquatic sediment samples were collected at one location (D-27) semiannually. This downstream location could be affected by Dresden's effluent releases. The following analysis was performed:

Gamma Spectrometry Sediment samples from the location were analyzed for gamma-emitting nuclides (Table C-IV.1, Appendix C). Cesium-137 (Cs-137) was found in both samples. The concentrations ranged from 153 pCi/kg dry to 218 pCi/kg dry.

B. Atmospheric Environment

1. Airborne

a. Air Particulates Continuous air particulate samples were collected from fourteen locations on a weekly basis. The fourteen locations were separated into four groups: On-site samplers (D-01, D-02 and D-03), Near-field samplers within 3.1 miles of the site (D-04, D-07, D-45, D-53, D-56 and D-58), Far-field samplers between 5 and 10 km (3.1 and 6.2 miles) from the site (D-08, D-10, D-14 and D-55) and the Control sampler between 10 and 30 km (6.2 and 18.6 miles) from the site (D-12). The following analyses were performed:

Gross Beta Weekly samples were analyzed for concentrations of beta 14

emitters (Table C-V.1 and C-V.2, Appendix C).

Detectable gross beta activity was observed at all locations.

Comparison of results among the four groups aid in determining the effects, if any, resulting from the operation of DNPS. The results from the On-Site locations ranged from 6 to 37E-3 pCi/m 3 with a mean of 16E-3 pCi/m 3 . The results from the Near-Field locations ranged from 5 to 40E-3 pCi/m 3 with a mean of 17E-3 pCi/m 3 . The results from the Far-Field locations ranged from 6 to 41 E-3 pCi/m 3 with a mean of 16E-3 pCi/m 3 . The results from the Control location ranged from 8 to 36E-3 pCi/m 3 with a mean of 16E-3 pCi/m 3 . Comparison of the 2016 air particulate data with previous year's data indicate no effects from the operation of DNPS. In addition a comparison of the weekly mean values for 2016 indicate no notable differences among the four groups (Figures C-8 through C-14, Appendix C).

Gamma Spectrometry Samples were composited quarterly and analyzed for gamma-emitting nuclides (Table C-V.3, Appendix C). Only naturally-occurring nuclides (not shown on the tables) were found in these composite samples. No anthropogenic nuclides were detected and all required LLDs were met.

These samples were consistent with historical quarterly results. All other nuclides were less than the MDC.

b. Airborne Iodine Continuous air samples were collected from fourteen locations (D-01, D-02, D-03, D-04, D-07, D-08, D-10, D-12, D-14, D-45, D-53, D-55, D-56 and D-58) and analyzed weekly for 1-131 (Table C-Vl.1, Appendix C). All results were less than the MDC for 1-131.

2. Terrestrial

a. Milk Milk (M) samples are typically collected biweekly at one control location (D-25) from May through October and monthly from November through April. Other than D-25, there are no additional milking animals within 1O kilometers (6.2 miles) of the site. The following analyses were 15

performed:

lodine-131 Milk samples from location D-25 were analyzed for concentrations of 1-131 (Table C-Vll.1, Appendix C). No 1-131 was detected and the LLD was met.

Gamma Spectrometry Milk samples from location D-25 were analyzed for concentrations of gamma-emitting nuclides (Table C-Vll.2, Appendix C).

Only naturally-occurring nuclides (not shown on the tables) were found in all samples. No other gamma-emitting nuclides were detected and all required LLDs were met.

b. Food Products Food product samples were collected at five locations (D-Control, D-Quad 1, D-Quad 2, D-Quad 3 and D-Quad 4) when available. Four locations, (D-Quad 1, D-Quad 2, D-Quad 3 and D-Quad 4) could be affected by Dresden's effluent releases. The following analysis was performed:

Gamma Spectrometry Samples from two locations were analyzed for gamma-emitting nuclides (Table C-Vlll.1, Appendix C). No nuclides were detected and all required LLDs were met.

C. Ambient Gamma Radiation Forty-six OSLO locations were established around the site. Results of OSLO measurements are listed in Tables C-IX.1 to C-IX.3, Appendix C.

Most OSLO measurements were below 30 mrem/quarter, with a range of 18.2 to 71.4 mrem/quarter. A comparison of the Inner Ring, Outer Ring and Other locations' data to the Control Location data, indicate that the ambient gamma radiation levels from the Control location (D-12-01 and D-12-02) were comparable.

16

D. Land Use Survey A Land Use Survey conducted on September 16, 2016 around the Dresden Nuclear Power Station (DNPS) was performed by EIML for Exelon Nuclear to comply with Section 12.6.2 of the Dresden Offsite Dose Calculation Manual (ODCM). The purpose of the survey was to document the nearest resident or industrial facility, milk producing animal, and livestock in each of the sixteen 22 % degree sectors within 10 km (6.2 miles) around the site. There were no changes required to the DNPS REMP as a result of this survey. The results of this survey are summarized below:

F. Summary of Results - Inter-Laboratory Comparison Program The primary laboratory 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:

17

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.

For the TBE laboratory, 156 out of 160 analyses performed met the specified acceptance criteria. Four analyses (Milk - Sr.:.90, Vegetation -

Sr-90, and Water - H-3 samples) did not meet the specified acceptance criteria for the following reasons and were addressed through the TBE Corrective Action Program.

Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.

18

1. Teledyne Brown Engineering's MAPEP March 2016 air particulate cross check sample is now being provided to TBE by Analytics.

MAPEP's policy is to evaluate as failed non-reported nuclides that were reported in the previous study. NCR 16-14 1a. Since the Sr-90 was reported in the previous MAPEP study but not in this study MAPEP evaluated the Sr-90 for Soil as failed. NCR 16-14 1b. The MAPEP March 2016 Sr-90 in vegetation was evaluated as failing a false positive test. In reviewing the data that was reported vs the data in LIMS, it was found that the error was incorrectly reported as 0.023 rather than the correct value of 0.230. If the value had been reported with the activity and correct uncertainty of 0.301 +/- 0.230, MAPEP would have evaluated the result as acceptable. NCR 16-14

2. Teledyne Brown Engineering's Analytics' March 2016 milk Sr-90 result of 15 +/- .125 pCi/L was higher than the known value of 11.4 pCi/L with a ratio of 1.32. The upper ratio of 1.30 (acceptable with warning) was exceeded. After an extensive review of the data it is believed the technician did not rinse the filtering apparatus properly and some cross contamination from one of the internal laboratory spike samples may have been transferred to the analytics sample.

We feel the issue is specific to the March 2016 Analytics sample.

NCR 16-26

3. Teledyne Brown Engineering's ERA November 2016 sample for H-3 in water was evaluated as failing. A result of 918 pCi/L was reported incorrectly due to a data entry issue. If the correct value of 9180 had been reported, ERA would have evaluated the result as acceptable. NCR 16-34

4. Teledyne Brown Engineering's Analytics' December 2016 milk Sr-90 sample result of 14. 7 +/- .26 pCi/L was higher than the known value of 10 pCi/L with a ratio of 1.47. The upper ratio of 1.30 (acceptable with warning) was exceeded. The technician entered the wrong aliquot into the LIMS system. To achieve a lower error term TBE uses a larger aliquot of 1.2L (Normally we use .6L for client samples). If the technician had entered an aliquot of 1.2L into the LIMS system, the result would have been 12.2 pCi/L, which would have been considered acceptable. NCR 16-35 19
