L Summary and Conchisions This report on the Radiological Environmental Monitoring Program conducted for the Byron Nuclear Generating Station by Exelon covers the period 1 January 2016 through 31 December 2016. During that time period, 1,482 analyses were performed on 1,320 samples.
In assessing all the data gathered for this report and comparing these results with preoperational data, it was concluded that the operation of BNGS had no adverse radiological impact on the environment.
Surface water samples were analyzed for concentrations of gross beta, tritium, Nickel-63 (Ni-63), and gamma-emitting nuclides, Ground water samples were analyzed for concentrations of tritium and gamma-emitting nuclides. Gross beta activities detected were consistent with those detected in previous years. All surface water samples analyzed for Ni-63 were less than the minimum detectable concentration. Tritium detected in downstream surface water was well below reportable limits and consistent with expected levels as a result of permitted liquid discharges.
Fish (commercially and/or recreationally important species) and sediment samples were analyzed for concentrations of Ni-63 and gamma-emitting nuclides. Non-plant produced Cesium-I 37 (Cs-I 37) activity was detected at one sediment location at a concentration of 225 pCi/kg. Low levels of Cs-I 37 are detected occasionally and are consistent with data from previous years and are not a result of plant effluents.
Air particulate samples were analyzed for concentrations of gross beta and gamma-emttrng nuchdes No fsson or actvaton products were detected High sensitivity lodine-I3I (1-131) analyses were performed on weekly air samples. All results were less than the minimum detectable concentration for 1-131.
Cow milk samples were analyzed for concentrations of 1-131 and gamma-emitting nuclides. All 1-131 results were below the minimum detectable activity.
No fission or activation products were found.
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 Luminescence Dosimeters (OSLO). Beginning in 2012, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry were deployed and Thermoluminescent 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 s dfferent than that used rn a TLD but has the same purpose (to measure dwect rathaton)

Introduction Byron Stafion, a two-unit PWR stafion, is located about two mes east of the Rock River and approximately three miles southwest of Byron in Ogle County, Illinois, The reactors are designed to have capacities of 1,268 and 1,241 MW gross, respectively. Unit One loaded fuel in November 1984 and went on line February 2, 1985 Unt Two went on hne January 9, 1987 The staton has been designed to keep releases to the environment at levels below those specified in the codes of federal regulations.
This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Landauer on samples collected during the period 1 January 2016 through 31 December2016.
A Objectves 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 Ill.
Program Description A.
Sample Collection Samples for the BNGS REMP were collected for Exelon Nuclear by Environmental Inc. (Midwest Labs). This section describes the general
collection methods used by Environmental Inc. to obtain environmental samples for the BNGS REMP in 2016, Sample locations and descriptions can be found in Table Bi and Figures Bi through B---5, Appendix B.
quatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, ground water, fish and sediment.
Two gallon water samples were collected weekly from two surface water locations (BY12 and BY-29 [Control location]) and quarterly from six ground water locations (BY-14-1, BY-18-i, BY-32, BY-35, BY-37 and BY-38). All samples were collected in new unused plastic bottles, which were rinsed with source water prior to collection. Fish samples comprising the flesh of golden redhorse, shorthead redhorse, quillback, river carpsucker, and channel catfish were collected semiannually at two locations, BY-29 (control) and BY-31. Sediment samples composed of recently deposited substrate were collected at two locations semiannually, BY-12 and BY-34 (control).
Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate, and airborne iodine. Airborne iodine and particulate samples were collected and analyzed weekly at eight locations (BYOl, BY-04, BY-06, BY-08, BY-21, BY-22, BY-23 and BY-24). The control location was BY-08. Airborne iodine and air particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters attached. The pumps ran 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 samples of milk and food products. Milk samples were collected monthly from January through April and November through December, and biweekly May through October. The control location was BY-26-2 and the indicator location was BY-20-1. AN samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfate and shipped promptly to the laboratory.
Food products were collected annually in July at five locations (BYControl, BY-Quad 1, BY-Quad 2, BY-Quad 3 and BY-Quad 4).
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 2012, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP).
Optically Stimulated Luminescent Dosimetry (OSLD) were deployed and Thermoluminescent Dosimetry (TLD) were discontinued. This change may result in a step change in readings, up or down, depending on site 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 sets. The OSLDs were exchanged quarterly and sent to Landauer for analysis. The OSLDs were placed at locations on and around the BNGS Station site as follows:
An j nor rin consisting of 16 locations (BY-i 01, BY-i 02, BY-I 03, BY 104, BY-105, BY-106, BY-107, BY-108, BY-109, BY-hO, BY-Ill, BY-112, BY-113, BY-114, BY-l15 and BY-116) near and within the site perimeter representing fence post doses (Le., at locations where the doses will be potentially greater than maximum annual offsite doses) from BNGS releases.
An outer rjq consisting of 16 locations (BY-201, BY-202, BY-203, BY-204, BY-205, BY-206, BY-207, BY-208, BY-209, BY-21 0, BY-21 1, BY-212, BY-213, BY-214, BY-215 and BY-2l6) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.
A pçJal interest set consisting of nine locations (BY-30I -1, BY-301 -2, BY-309-l, BY-309-2, BY-309-3, BY-309-4, and BY-314-2) to measure possible exposures from on-site storage facilities.
An other set consisting of seven locations (BY-Oh, BY-04, BY-06, BY-2I, BY-22, BY-23 and BY-24) at locations where air samplers are present.
The balance of one locaton (BY-08) representng the control area The specific OSLD locations were determined by the following criteria:
I The presence of relatively dense populaton, 2.
Site meteorological data taking into account distance and elevation
-4
for each of the sixteen22 1/2 degree sectors around the site, where estimated annua dose from BNGS, if any, woud be most significant; 3.
On hilts free from oca obstructions and within sight of the vents (where practic&);
4.
And near the cosest dweiling to the vents in the prevailing downwind direction if appNcabe.
Two OSLDs were paced at each ocation ocated at a minimum of five feet above ground eveL The OSLDs were exchanged quartery and sent to Landauer for anaysis.
B.
Sampe Anaysis This section describes the genera anaytic& methodoogies used by TBE to anayze the environmenta sampes for radioactivity for the BNGS REMP in 2016. The anaytica procedures used by the aboratory are isted in Tabe 8-2.
n order to achieve the stated objectives, the current program incudes the foNowing anayses:
1.
Concentrations of beta emitters in surface water and air particuates 2.
Concentrations of gamma emitters in ground and surface water, air particuates, milk, fish, sediment and vegetation 3.
Concentrations of tritium in ground and surface water 4.
Concentrations of odine-1 31 in air and milk 5.
Concentrations of Nickel-63 in surface water, fish and sediment 6.
Ambient gamma radiation eves at various site environs C.
Data Interpretation The radiological and direct radiation data collected prior to Byron Nuclear Generabng Staton becomng operatonal were used as a basehne wth which these operational data were compared. For the purpose of this report, Byron Nuclear Generating Station was considered operational at initial criticality.
In addition, data were compared to previous year&
operatonal data for consstency and trendng Several factors were
important in the interpretation of the data:
Lower Limit of Detection and Minimum Detectable Concentration The lower hmt of detecton (LLD) was defned as the smaNest 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 BNGS detection capabilities for environmental sample analysis.
The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after-the-fact estimate of the presence of activity.
2.
Net Activiyjculation 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 surface water, ground water and vegetation twelve nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, 1-131, Cs-I 34, Cs-137, Ba-140 and La-140 were reported.
For fish, sediment, air particulate and milk eleven nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, Cs-I 34, Cs-I 37, 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 BNGS REMP had a sample recovery rate in excess of 99%.
Sample anomalies and missed samples are listed in the tables below:

Results and Discussion A.
Aquafic Environment 1.
Surface Water Samples were taken weekly and composited monthly at two locations (BY-I 2 and BY-29). Of these locations only BY-I 2 located downstream, could be affected by Byron Nuclear Generating Stations effluent releases. The following analyses were performed:
Gross Beta Samples from both locations were analyzed for concentrations of gross beta (Table CL1, Appendix C). The values ranged from 30 to 65 pCi/L Concentrations detected were consistent with those detected in previous years (Figure CI, Appendix C).
Tntum Quarterly composites of weekly collections were analyzed for tritium activity (Table Cl.2, Appendix C). Tritium was detected in four samples. The concentrations ranged from 371 2200 pCi/L (Figure C2, Appendix C). Tritium detected in downstream surface water was well below reportable limits and consistent with expected levels as a result of permtted hqwd dscharges Nickel Samples from both locations were analyzed for concentration of Ni-63 (Table Cl.3, Appendix C). All results were less than the minimum detectable concentration.
Gamma Spctprn Samples from both locations were analyzed for gamma-emitting nuclides (Table CIA, Appendix C). No nuclides were detected, and all required LLDs were met.
2.
Ground Water Quarterly grab samples were collected at seven locations (BY14-1, BY1 8-1, BY-32, BY-35, BY-37 and BY-38). These locations could be affected by Byron Nuclear Generating Stations effluent releases. The following analyses were performed:
Tritium Quarterly grab samples from the locations were analyzed for tritium activity (Table C-L1, Appendix C). No trftium was detected, and the required LLD was met (Figures C3 through C-7, Appendix C).

Location BY-31 could be affected by Byron Nuclear Generating Stations effluent releases. The following analyses were performed:
Nickel The edible portion of fish samples from both locations was analyzed for Ni-63 (Table CllLl, Appendix C). Nickel-63 was not detected and the required LLD was met.
Gamma Spectrometr The edible portion of fish samples from both locations was analyzed for gamma-emitting nuclides (Table Clll.1, Appendix C).
No nuclides were detected, and all required LLDs were met.
4.
Sediment Aquatic sediment samples were collected at two locations (BY-I 2 and BY-34) semiannually. BY-12, located downstream, could be affected by Byron Nuclear Generating Stations effluent releases.
The following analyses were performed:
Nickel Sediment samples from both locations were analyzed for Ni63 (Table CV.1, Appendix C). Ni63 was not detected and the required LLD was met.
Gamma Spectromeiy Sediment samples from both locations were analyzed for gamma-emitting nuclides (Table CV.1, Appendix C). Cesium-137 was detected in one sample. The concentration was 225 pCi/kg dry.
The concentrations detected was consistent with those detected in previous years and is not a result of plant effluents. No other nuclides were detected, and aN required LLDs were met.
B.
Atmospheric Environment Airborne a.
Air Particulates Continuous air particulate samples were coHected from eight locations on a weekly basis. The eight locations were separated into three groups: Nearsite samplers within 4 km of the site (BY-21, BY-22, BY-23 and BY-24), Far Field samplers between 4 and 10 km of the site (BY-Ol, BY-04 and BY-06) and the Control sampler between 10 and 30 km from the site (BY-08). The following analyses were performed:
Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table CV.1 and C.-V.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 BNGS.
The results from the Nearsite locations (Group I) ranged from 6 to 41 E3 pCi/rn 3 with a mean of 16 E3 pCi/rn 3
The results from the Far Field locations (Group II) ranged from 6 to 39 E3 pC/m 3 wth a mean of 16 E-3 pCUm 3
The results from the Control location (Group HI) ranged from
8 to 36 E3 pCi/rn 3 with a mean of 16 E3 pCi/rn 3
Comparison of the 2016 air particulate data with previous years data indicate no effects from the operation of BNGS.
In addition, a comparison of the weekly mean values for 2016 indicate no notable differences among the three groups (Figures C8 through C12, Appendix C).
Gamma Spectromejry Weekly samples were composited quarterly and analyzed for garnmaemiffing nudlldes (Table CV.3, Appendix C). No nudildes were detected, and all required LLDs were met.
b.
Airborne Iodine Continuous air samples were collected from eight locations (BY-01, BY04, BY06, BY08, BY21, BY-22, BY23 and BY24) and analyzed weekly for p131 (Table C.-Vl.1, Appendix C). AN results were less than the minimum detectable concentration for [1 31.
2.
Terrestrial a.
Milk Samples were collected from two locations (BY201 and BY26-2) monthly from January to April and November through December, and biweekly May through October.
The following analyses were performed:
lodine131 Milk samples from all locations were analyzed for concentrations of [131 (Table CVlL1, Appendix C). No nuclides were detected, and all required LLDs were met.
Garnmaçrometry Each milk sample was analyzed for concentrations of gammaemitting nuclides (Table CVlL2, Appendix C). No nudildes were detected, and all required LLDs were met.
b.
Vegetation Vegetation samples were collected at five locations (BYControl, BYQuad 1, BYQuad 2, BYQuad 3 and 11
BY-Quad 4). Four locations (BY-Quad 1, BY-Quad 2, BY-Quad 3 and BY-Quad 4) could be affected by Byron Nuclear Generating Stations effluent releases. The following analysis was performed:
Gamma Sectrometry Samples from all locations were analyzed for gamma-emitting nudlldes (Table CVlll.1, Appendix C). No nudlldes were detected, and all required LLDs were met.
C.
Ambient Gamma Radiation Ambient gamma radiation levels were measured utHizing OSLDs.
Ninety-one OSLD locations were established around the site. Resu[ts of OSLD measurements are listed in Tables C!Xi to C-iX3, Appendix C.
All OSLD measurements were below 30 mR/standard quarter, with a range of 16 to 28 mR/standard quarter. A comparison of the Inner Ring, Outer Rang, Specal Interest Other and Control Locaton data ndcate that the ambient gamma radiation levels were comparable among the groups.
D.

Summary of Results Inter-Laboratory Comparison Program The primary laboratory analyzed Performance Evaluation (PE) samples of ar partculate, aw odne (charcoal) mlk sol, vegetahon and water (including fish) matrices (Appendix D). The PE sample matrices were chosen based on the types of samples submitted to the primary laboratory for analysis. The selected parameters for the PE samples are based on the appropriate matrices, methodologies and geometries, which include geometries that are comparable. The PE samples, supplied by Analytics Inc., Environmental Resource Associates (ERA) and DOEs Mixed Analyte Performance 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, TBEES evahiates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.
2.
ERA Evaluation Criteria ERAs evaluation report provides an acceptance range for control and warning limits with associated flag values. ERAs acceptance Hmits are estabHshed per the USEPA, NELAC, state specific PT program requirements or ERAs SOP for the Generation of Performance Acceptance Limits, as appHcable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage Hmit promulgated under the appropriate regulatory document.
3.
DOE Evaluation Criteria MAPEPs 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 s acceptable wth warrnng when a mean result falls vi the range from +/-20% to +/-30% of the reference value (Le, 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 obtarned at commercal nuclear power facthtes 1.
Teledyne Brown Engineerings MAPEP March 2016 air particulate cross check sample is now being provided to TBE by Analytics.
MAPEPs policy is to evaluate as failed non reported nuclides that were reported vi the prevous study Svice the Sr-90 was reported in the previous MAPEP study but not in this study MAPEP evaluated the Sr90 for SoN as faNed. NCR l6l4 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 wth the actvty and correct uncertanty of 0.301 +/- 0.230, MAPEP would have evaluated the result as acceptable. NCR 16-14 2.
Teledyne Brown Engineerings Analytics March 2016 mUk 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 Engineerings 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 Engineerings 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 aNquot into the LIMS system. To achieve a lower error term TBE uses a larger aliquot of I.2L (Normally we use.6L for client samples).
If the technician had entered an aliquot of I.2L into the LIMS system, the result would have been 12.2 pCiIL, which would have been considered acceptable. NCR 16-35 The Inter-Laboratory Comparison Program provides evidence of in control counting systems and methods, and that the laboratories are producing accurate and reliable data.

SUMMARY
Calculations based on gaseous and quid effluents and meteoroogical data indicate that pubc dose due to radioactive material attributable to Byron Station during the period does not exceed regulatory or Offsite Dose Calculafion Manual (ODCM) Hmits.
The Total Effective Dose Equivalent (TEDE) due to licensed activities at Byron Station calculated for the maximum exposed individual for the period is 261 E01 mrem. The annual ilmit on TEDE is 100 mrem.
The assessment of radiation doses to the public is performed in accordance with the ODCM. The resufts of these analyses confirm that the station is operating in compliance with IOCFR5O Appendix I, IOCFR2O and 4OCFRI9O.
There were no additional operational controls implemented which affected the areas of radiological effluents in 2016.
There were no measurements which exceeded the reporting levels, including any which would not have been attributable to station effluents.
The results of the current radiological environmental monitoring program are approximately the same as those found during the preoperational studies conducted at Byron Station.
INTRODUC11ON Liquid effluents from Byron Station are released to the Rock 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 weekly grab samples and grab samples of batch releases prior to the release of noble gases as well as continuously collected composite samples of iodine and particulate radioactivity sampled during the course of the year. The results of effluent analyses are summarized on a monthly basis.
Airborne concentrations of noble gases, 1-131, and particulate radioactivity in offsite areas are calculated using isotopic composition of effluents and meteorological data.
C-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 Byron Station to measure changes in radiation or radioactivity levels that may be attributable to station operation. If significant changes attributable to Byron 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),
nhalaton, vegetatfion meat and mlk Lqud pathways nclude potable water and freshwater fish. The critical pathway for 2016 gaseous dose was vegetation. The critical pathway for 2016 liquid dose was freshwater fish.

3.0 DOSE TO MAN 3.1 Gags Effluent Pathwa Table 3.2-1 summarizes the doses resulting from r&eases of airborne radioactivity via the different exposure pathways.
3.1.1 Noble Gases 3.1.1.1 Gamma Dose Rates Offsite Gamma air and whole body dose rates are shown in Table 3.2-1 and were calculated based on measured release rates, isotopic composition of the noble gases, and average meteorological data for the period. Dose rates based on concurrent meteorological data are shown in Table 3.4-1. Based on measured effluents and average meteorological data, the maximum gamma air dose was 5.13E-05 mrad based on measured effluents and average meteorological data, and 9.35E-06 mrad based on measured effluents and concurrent meteorological data. (Table 3.4-1).
3.1.1.2 Beta Air and Skin Dose Rates The range of beta particles in air is r&atively smaU (on the order of a few meters or less); consequently, plumes of gaseous effluents may be considered semi-infinite for purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to senstve skn tssues s dfflcult 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 based on measured effluents and average meteorological data was 1.53E-05 mrem, and I.31 E-05 mrem based on measured effluents and concurrent meteorological data.
The maximum offsite beta air dose for the year based on measured effluents and average meteorological data was 2.30E05 mrad. The beta air dose based on measured effluents and concurrent meteorological data was 1.73E-05 mrad.
3.1.2 Radioactive dine & Particulate The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. p131 released during routine operation of the station may be made available to man resulting in a dose to the thyroid. C14 is also included in this category. C14 exhibits a capacity to concentrate in bone. C-14 is released in gaseous form and is absorbed into vegetation through photosynthesis. The principal pathways of interest for C14 are the consumption of vegetation by humans and milk from which animals have ingested C-14 through the consumption of vegetation. With the addition of C14 to plant effluents, 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 C14) to any organ was 6.93EO1 mrem (child/bone) based on measured effluents and average meteorological data and 6.65EO1 rnrem based on measured effluents and concurrent meteorological data. The maximum dose from radioactive iodine and particulate (including C-14) to the whole body was 1.41 EO1 mrem (child) based on measured effluents and average meteorological data and I.36E-O1 mrem based on measured effluents and concurrent meteorological data.
3.1.3 Gaseous Total Dose The maximum total dose from gaseous releases to any organ was 6.93EO1 mrem (child/bone) based on measured effluents and average meteorological data, and 6.65EO1 mrem (child/bone) based on measured effluents and concurrent meteorological data.
The maximum total dose from gaseous releases to the whole body was 1.41 EO1 mrem (child) based on measured effluents and average meteorological data, and I 36EO1 mrem (child) based on measured effluents and concurrent meteorological data.
3.2 qjd Effluent Pathways The principal pathways through the aquatic environment for potential doses to man from Hquid waste are ingestion of potable water and eating aquatic foods. Liquid dose was calculated based on the ingestion of potable water and sport fish.
It should be noted, however, there were no communities within 10 km downstream of the plant using the Rock River for drinking water. NRCdeveloped equations were used to calculate the doses to the whole body, bone, liver, thyroid, kidney, lung, lower GI tract, and skin. Specific parameters for use in the equations are given in the Exelon Offsite Dose Calculation Manual (ODCM). The maximum dose from Hquid releases to any organ was I.73E-O1 mrem (adultlgHli). The maximum dose from liquid releases to the whole body was I Al E0l mrem (adult).
3.3 Total Dose The maximum total dose to any organ via both gaseous and liquid effluents to any organ is 7.74E01 mrem (child/bone). The maximum dose to the whole body via both gaseous and liquid effluents is 2.61 E01 mrem (child).
3 4 Assessment of Dose to Member of Pubhc Byron Station did not exceed any of the dose limits as shown below based on concurrent or historical meteorological data.
The RETS limits on dose or dose commitment to a member of the public due to radioactive materials in liquid effluents from each reactor is 1.5 mrem to the whole body or 5 mrem to any organ during any calendar quarter and 3 mrem to the whole body or 10 mrem to any organ during a calendar year.
The RETS limits on air dose in noble gases released in gaseous effluents to a member of the public from each reactor is 5 mrad for gamma radiation or 10 mrad for beta radiation during any calendar quarter and 10 mrad for gamma radiation or 20 mrad for beta radiation during a calendar year.
The RETS hmts on dose to a member of the pubhc due to radoactve iodine & particulate with halNives greater than eight days in gaseous effluents released from each reactor is 7.5 mrem to any organ during any calendar quarter and 15 mrem during a calendar year.
The IOCFR2O Hmit on Total Effective Dose Equivalent to indMdual members of the pubhc is 100 mrem during a calendar year.
The 4OCFRI9O limits on individual members of the public is 25 mrem to the whole body, 25 mrem to any organ (except thyroid), and 75 mrem to the thyroid.
4.0 SITE METEORQLO Detailed records of the site meteorological measurements taken during each calendar quarter of the year are maintained by the meteorological vendor, retained on site, and are available upon request. The data are presented as cumulative joint frequency distributions of the wind direction for the 250 level and wind speed class by atmospheric stability class determined from the temperature difference between the 250 and 30 levels. Data recovery for all measurements on the meteorological tower was 99.8% during 2016.

L Summary and Concu&ons n 2006, Ex&on nsttuted a comprehensve morntonng program to evauate the impact of station operations on groundwater in the vicinity of Byron Nuclear Generating Station. The monitoring was conducted in two phases. Phase I of the monitoring was part of a comprehensive study initiated by Exelon to determine whether groundwater or surface water at and in the vicinity of Byron Nuclear Generating Station had been adversely impacted by any releases of radionuclides. Phase I was conducted by Conestoga Rovers and Associates (CRA) and the conclusions were made avaHable to state and federal regulators as well as the public.
Phase 2 of the RGPP was conducted by Exelon corporate and station personnel to initiate follow up of Phase I and begin long-term monitoring at groundwater locations selected during Phase 1. This is the ninth in a series of annual reports on the status of the Radiological Groundwater Protection Program (RGPP) conducted at Byron Nuclear Generating Station. This report covers groundwater and surface water samples collected from the environment both on and off station property in 2016. During that time period, 116 analyses were performed on 54 samples from 16 locations.
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 samples tested.
In the case of tritium, Exelon specified that its laboratories achieve a lower limit of detection 10 times lower than that required by federal regulation.
In 2016, one surface water and fifteen (15) Radiological Groundwater Protection Program (RGPP) monitoring wells were sampled. The samples were obtained throughout the year and analyzed for tritium In addition, for the samples obtained in June, a study of gamma, beta, and alpha radioisotopes was performed in accordance with Nuclear Energy Institute (NEI) 07-07, Groundwater Protection Initiative. Three wells contained levels of tritium above the lower limit of detection (LLD) of 200 pCi/L. They were: AR-4, with concentrations ranging from 381 661 pCi/L; AR-7, with concentrations ranging from 213 421 pCi/L; and AR-I 1, with concentrations ranging from 588 920 pCi/L. Wells AR-4 and AR-i I are near the Circulating Water Blowdown piping, where historical leakage through vacuum breakers was known to have occurred. Tritium concentrations in these wells have gradually decreased since being first sampled in 2006 Well AR-7 is located on-site, just west of plant structures Tritium has been measured in this well just above detectable limits on an intermittent basis since the well was first drilled in 2006. The tritium present in this well is at or below tritium levels that have been measured in rainwater as a result of precipitation recapture from permitted gaseous releases and it is not believed to be the result of new leak(s).
In August 2014, a break in the AR-7 well piping was discovered about six feet below the surface that could have served as the entry point for tritium in the
recapture water. Should the water in these aquifers migrate to off-s[te wells used for drinking, the off-site dose consequence from tritium present in any of these three wells would be negligible. There are no existing or new leaks evident at the site and all groundwater well sample results are well below the drinking water standard of 20,000 pCIL tnhum Strontium-89 (Sr-89) and Strontium-90 (Sr-90) were not detected in any samples above their respective LLDs of 10 and 1 pCiIL.
Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second quarter sampling in 2016.
Gross Alpha (dissolved) was not detected in any of eight groundwater locations.
Gross Alpha (suspended) was detected in one of eight groundwater locations at a concentration of 2.4 pCi/L.
Gross Beta (dissolved) was detected in seven of eight groundwater locations.
The concentrations ranged from 1.8 to 26.7 pCiIL. Gross Beta (suspended) was detected in one of eight groundwater locations at a concentration of 2.6 pCiIL.
The concentrations of Gross Alpha and Gross Beta, which are slightly above detectable levels, are considered to be background and are not the result of plant effluents.
Hard-To-Detect analyses were not performed in 2016.
In assessing all the data gathered for this report, it was concluded that the operation of Byron Nuclear Generating Station had no adverse radiological impact on the environment, and there are no known active releases into the groundwater at Byron Nuclear Generating Station.
lntroducton The Byron Station, a two-unit PWR station, is located about two miles east of the Rock River and approximately three miles southwest of Byron in Ogle County, Illinois.

Characteristics of Tritium (H-3)
Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called tritiated water. The chemical properties of tritium are essentially those of ordinary hydrogen Tritiated water behaves the same as ordinary water in both the environment and the body. Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Tritium is excreted primarily through urine with a clearance rate characterized by an effective biological half-life of about 14 days Wthrn one month or so after ngeston, essentally all tntum s cleared. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period.
Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotopes lithium-7 and/or boron-lO are activated to produce tritium.
Like normal water, tritiated water is colorless
and odorless. Tritiated water behaves chemicaNy and physicaNy like non tritiated water in the subsurface, and therefore tritiated water wiN travel at the same velocity as the average groundwater v&ocity.
TrWum has a half-fe of approximately 12.3 years. It decays spontaneously to Helium-3(
3 He). This radioactive decay releases a beta partcle (low-energy electron) The radioactve decay of tntum s the source of the health risk from exposure to tritium. Tritium is one of the least dangerous radionucNdes because it emits very weak radiation and leaves the body relatively quickly. Since tritium is almost always found as water, it goes directly into soft tissues and organs. The associated dose to these tissues is generally uniform and is dependent on the water content of the specific tissue.

Program Description A.
Sample Analysis This section describes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the Byron Nuclear Generating Station RGPP in 2016.
In order to achieve the stated objectives, the current program includes the following analyses (as required by procedure):
1.
Concentrations of gamma emitters in groundwater 2
Concentrahons of stronhum n groundwater 3.
Concentrations of tritium in groundwater 4.
Concentrations of gross alpha and gross beta in groundwater B.
Data Interpretation The radoIogcaI data collected pnor to Byron Nuclear Generatng Staton becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, Byron Nuclear Generating Station was considered operational at initial criticality.
Several factors were important in the interpretation of the data:
I Lower Umt of Detecton and Mnmum Detectable Concentraton 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 Uncf1fly The estimated uncertainty in measurement of tritium in environmenta sampes is frequenty on the order of 50% of the measurement vague.
StatisticaNy, the exact vaue of a measurement is expressed as a range with a stated eve of confidence. The convention is to report resufts with a 95% ev& of confidence. The uncertainty comes from cahbration standards, sampe voume or weight measurements, samphng uncertainty and other factors. Ex&on reports the uncertainty of a measurement created by statistica process (counting error) as we as aN sources of error (Tot&
Propagated Uncertanty or TPU)
Each resu[t has two vaues c&cuated Exelon reports the TPU by foHowng the resuft wth pus or mnus +/- the estmated sampe standard devaton as TPU, that is obtained by propagating aN sources of anaytica uncertainty in measurements.
Anaytica uncertainties are reported at the 95% confidence eve in ths report for reportng consistency wfth the AREOR C.
Background An&ysis A pre-operatona radoogca envwonmenta morntonng program (pre operatona REMP) was conducted to estabhsh background radoactvty eves pnor to operaton of the Staton The envwonmenta meda samped and an&yzed dunng the pre-operatona REMP were atmosphenc radaton, faN-out, domestc water, surface water, manne hfe, and foodstuffs. The resu[ts of the monitoring were detaied in the report entUed, Enwronmental Radiological Monitoring for Byron Nuclear Generating Nuclear Power Station Commonwealth Edison Company, Annual Report 1984, April 1985 The pre-operatona REMP contaned analytca resufts from sampes coNected from the surface water and groundwater. AN groundwater sampes hsted rn the pre-Operatona REMP report were <200 pC/L I
Background Concentratons of Tntum The purpose of the following discussion is to summarize background measurements of tntum rn vanous meda performed by others Addtona deta may be found by consuftrng references (CRA 2006)
a.
Tritium Production Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., rnanmade) 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 cyde. 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 Sr90 comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased sign ificanfly during the I 950s and early 1 960s, and later with additional testing, resu[ting 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 USEPAs RadNet database. GNIP provides tritium precipitation concentration data for samples collected worldwide from 1960 to 2006.
RadNet provides tritium precipitation concentration data for samples collected at stations throughout the U.S. from 1960 up to and including 2006. Based on GNIP data for sample stations located in the U.S. Midwest, tritium concentrations peaked around 1963. This peak, which approached 10,000 pCi/L for some stations, coincided with the atmospheric testing of thermonuclear weapons. Tritium concentrations in surface water showed a sharp dechne up unhl 1975 followed by a gradual dechne snce that hme Tnhum concentrahons 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 I 960s 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 pCiIL.
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 radioanalytical 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.
Groundwater Results Groundwater Samples were collected from on and offsite wells throughout the year in accordance with the station radiological groundwater protection program Analytical results and anomalies are discussed below Tritiurn Samples from all locations were analyzed for tritium activity (Table Bl 1, Append ix B) Tritium values ranged from less than the detection limit to 920 pCi/L Outside of the station boundary, tritium concentrations were all less than detection limit (<200 pCi/L) This is based on evaluation of groundwater sample results obtained as part of the Byron Station REMP In 2016, fifteen (15) Radiological Groundwater Protection Program (RGPP) monitoring wells were sampled The samples were obtained throughout the year and analyzed for tritium
n addWon, a study of gamma, beta and apha radosotopes was performed n accordance w[th Nucear Energy nstftute (NEt) 07-07, Groundwater Protecfion nitiative, for the sampes obtained n June. Three wells contained lleves of tritium above the sower Nmit of detection (LLD) of 200 pCi/L. They were: AR-4, with concentrations ranging from 381 661 pCi/L; AR-7, with concentrations ranging from 213 421 pCi/L; and AR 11, with concentrations ranging from 588 920 pCi/L. Wells AR-4 and AR-I I are near the Circuating Water Bowdown piping, where historica eakage through vacuum breakers was known to have occurred, Tritium concentrations in these wells have gradually decreased since being first samped in 2006. Well AR-7 is ocated on-site, just west of pant structures. Tritium has been measured in this well just above detectabe imits on an intermittent basis since the well was first drilled in 2006. The tntum present n ths well s at or beow tntum Deves that have been measured rn raniwater as a resut of precptaton recapture from permtted gaseous r&eases and it is not beNeved to be the resu[t of new eak(s). n August 2014, a break in the AR-7 well piping was discovered about six feet b&ow the surface that coud have served as the entry point for tritium in the recapture water. There are no existing or new eaks evident at the site and all groundwater well sampe resuts are well b&ow the drinking water standard of 20,000 pCi/L tritium. The tritium detected in groundwater sampes has been isoated to the Gaena-Patteville aquifer, which is isoated from the deeper regiona groundwater aquifer by the semi-confining Genwood Formation. Groundwater quaity data from producton wells and morutonng wells at the staton ocated beow thus aquifer do not indicate concentrations of tritium greater than the LLD of 200 pC/L As such, the tntum impact s hmted to the Gaena-Pattevlle aquifer Strontium Strontium-89 (Sr-89) and Strontium-90 (Sr-90) were not detected in any sampes above their respective LLDs of 10 and 1 pCiIL.
Gross Apha and Gross Beta (dssoved and suwended)
Gross Apha and Gross Beta an&yses in the dissoved and suspended fractions were performed on groundwater sampes during the second quarter samphng ni 2016 Gross Apha (dssoved) was not detected ni any of eght groundwater ocatons Gross Apha (suspended) was detected ni one of eght groundwater ocations at a concentration of 2.4 pCi/L.
Gross Beta (dssoved) was detected ni seven of eght groundwater ocatons The concentratons ranged from 1 8 to 26 7 pC/L Gross Beta (suspended) was detected n one of eght groundwater ocatons at a concentraton of 2 6 pCIL
The concentrations of Gross Apha and Gross Beta, which are sllghfly above detectabe eves, are considered to be background and are not the resu[t of pant effluents.
Gamma Emitters Gamma-emiffing radionudlldes associated with Ncensed pant operations were not detected at concentrations greater than their respective LLDs in any of the sampes during 2016.
Hard-To-Detect Hard-To-Detect anayses were not performed n 2016 B
