1.0 PURPOSE The Annual Radiological Environmental Operating Report is published pursuant to Section 6.6.2 of the Nine Mile Point Unit 1 (NMPl) Technical Specifications and Section 5.6.2 of the Nine Mile Point Unit 2 (NMP2) Technical Specifications. The Offsite Dose Calculation Manual (ODCM) requires that the results from the annual Radiological Environmental Monitoring Program (REMP) be provided to the Nuclear Regulatory Commission by May 15th of each year.

This report describes the Radiological Environmental Monitoring Program (REMP), the implementation of the program, and the results obtained as required by the Offsite Dose Calculation Manual (ODCM). The report also contains the analytical results tables, data evaluation, dose assessment, and data trends for each environmental sample media. Also included are results of the land use census, historical data, and the Environmental Laboratory's performance in the Quality Assurance Interlaboratory Comparison Program.

The REMP is a comprehensive surveillance program, which is implemented to assess the impact of site operations on the environment and compliance with 10 CFR 20, 40 CFR 190 and 10 CFR 72.

Samples are collected from the aquatic and terrestrial pathways applicable to the site. The aquatic pathways include Lake Ontario fish, surface waters and lakeshore sediment. The terrestrial pathways include airborne particulate and radioiodine, milk, food products and direct radiation.

During 2016 there were 2,181 analyses performed on environmental media collected as part of the REMP. These results demonstrate that there is no significant or measurable radiological impact from the operation of either the NMPl or NMP2 facilities. The 2016 results for all pathways sampled are consistent with the previous five-year historical results and exhibited no adverse trends.

In summary, the analytical results from the 2016 REMP demonstrate that the routine operation of both facilities at the Nine Mile Point Nuclear Station had no significant or measurable radiological impact on the environment. The pro gram continues to demonstrate that the dose to a member of the public, as a result of the operation of NMP 1 and NMP2, remains significantly below the federally required dose limits specified in 10 CFR 20, 40 CFR 190 and 10 CFR 72.

2.0 INTRODUCTION

The Nine Mile Point Nuclear Station is owned by Nine Mile Point Nuclear Station, LLC and operated by the Nuclear Regulatory Commission (NRC) licensee, Exelon Generation Company, LLC. This report is submitted in accordance with Appendix A (Technical Specifications) Section 6.6.2 to License DPR-63, Docket No. 50-220 for Nine Mile Point Nuclear Station, Unit 1, and Appendix A (Technical Specifications) Section 5.6.2 to License NPF-69, Docket No. 50-410 for Nine Mile Point Nuclear Station, Unit 2, for the calendar year 2016.

Nine Mile Point Unit 1 (NMPl) and Nine Mile Point Unit 2 (NMP2) Radiological Environmental Monitoring Program (REMP) requirements reside within the NMP 1 Offsite Dose Calculation Manual (ODCM) and NMP2 ODCM, respectively. Throughout this report, references will be made to the ODCM. This refers to both the NMPl ODCM and the NMP2 ODCM.

2.1 PROGRAM HISTORY Environmental monitoring at the Nine Mile Point (NMP) site has been ongoing since 1964. The program includes five years of pre-operational data, which was conducted prior to any reactor operations. In 1968, the Niagara Mohawk Power Company began the required pre-operational environmental site testing program. This pre-operational data serves as a reference point to compare later data obtained during reactor operation. In 1969, the NMPl reactor, a 1,850 megawatt-thermal (MWt) Boiling Water Reactor (BWR) began full power operation. In 1975, the James A. FitzPatrick Nuclear Power Plant, owned and operated at that time by the New York Power Authority, began full power operation. The FitzPatrick plant, a 2,536 MWt BWR, occupies the east sector of the Nine Mile Point site, approximately 0.57 miles east ofNMPl. In 1988, the NMP2 reactor also owned and operated by Nine Mile Point Nuclear Station, LLC, began full power operation. This 3,988 MWt BWR is located between the Nine Mile Point Unit 1 and FitzPatrick sites.

In 1985, the individual Plant Effluent Technical Specifications were standardized to the generic Radiological Effluent Technical Specifications, much of which was common to the two reactors, and subsequently NMP2. Subsequent Technical Specification amendments relocated the REMP requirements to the ODCM for all three plants. Data generated by the Radiological Environmental Monitoring Program (REMP) is shared, but each utility reviews and publishes their own annual report. On November 21, 2000 the ownership and operation of the James A. FitzPatrick Nuclear Power Plant was transferred from the New York Power Authority to Entergy Nuclear FitzPatrick, LLC and Entergy Nuclear Operations, Inc. On November 7, 2001, the ownership of the NMPl and NMP2 facilities was transferred to Constellation Energy Nuclear Group (CENG). In March 2012, Constellation Energy merged with Exelon Generation and prior to March 25, 2014, Exelon Generation was an intermediate 50.01 percent parent company of CENG, which is the parent company owner of Nine Mile Point Nuclear Station, LLC. Following the transfer, Exelon Generation remains an intermediate parent company and also became the co-licensee of Nine Mile Point Nuclear Station, LLC and the operator ofNMPl and NMP2.

In summary, three Boiling Water Reactors, which together generate 8,374 MWt, have operated collectively at the Nine Mile Point site since 1988. A large database of environmental results from the exposure pathways have been collected and analyzed to evaluate the potential impact from reactor operations.

2.2 SITE DESCRIPTION The NMP site is located on the southeast shore of Lake Ontario in the town of Scriba, approximately 6.2 miles northeast of the city of Oswego. The nearest metropolitan area is located approximately 36 miles south southeast of the site. The reactors and support buildings occupy a small shoreline portion of the 900-acre site. The land, soil of glacier deposits, rises gently from the lake in all directions. Oswego County is a rural environment, with about 15% of the land devoted to agriculture.

2.3 PROGRAM OBJECTIVES The objectives ~fthe Radiological Environmental Monitoring Program (REMP) are to:

1. Measure and evaluate the effects of plant operation on the

environs and to verify the effectiveness of the controls on radioactive material sources.

2. Monitor natural radiation levels in the environs of the NMP site.

3. Demonstrate compliance with the requirements of applicable federal regulatory agencies, including Technical Specifications and the Offsite Dose Calculation Manual.

2-2

3.0 PROGRAM DESCRIPTION To achieve the objectives listed in Section 2.3, an extensive sampling and analysis program is conducted every year. The Nine Mile Point Nuclear Station (NMPNS) Radiological Environmental Monitoring Program (REMP) consists of sampling and analysis of various media that include:

Air

Fish

Food Products

..* Milk Shoreline Sediment

Surface Waters In addition, direct radiation measurements are performed using thermoluminescent dosimeters (TLDs). These sampling programs are outlined in Table 3.0-1 and Table 3.0-2. The NMPNS REMP sampling locations are selected and verified by an annual Land Use Census. The accuracy and

. precision of the program is assured by participation in an Interlaboratory Comparison Quality Assurance Program (ICQAP). In addition to the participation in the ICQAP, sample splits are provided to the New York State Department of Health for cross-checking purposes.

Sample collections for the radiological program are accomplished by a dedicated site environmental staff from both the Nine Mile Point Nuclear Stations (NMPNS) and James A. FitzPatrick Nuclear Power Plant (JAFNPP). The site staff is assisted by a contracted environmental engineering company, EA Engineering, Science and Technology, Inc. (EA).

3.1 SAMPLE COLLECTION METHODOLOGY 3.1.1 SHORELINE SEDIMENTS Shoreline sediment is collected at one area of existing or potential recreational value. One sample is also collected from a location beyond the influence of the site. Samples are collected as surface scrapings to a depth of approximately one inch. The samples are placed in plastic bags, sealed and shipped to the lab for analysis. Sediment samples are analyzed for gamma emitting radionuclides.

Shoreline sediment sample locations are listed in Section 3.3, Table 3.3-1 and shown in Figure 3.3-5 3.1.2 FISH Samples of available fish species that are commercially or recreationally important to Lake Ontario; such as Brown Trout, Chinook Salmon, Smallmouth Bass, and Walleye, are collected twice per year, once in the spring and again in the fall. Indicator samples are collected from a combination of the two onsite sample transects located offshore from the site. One set of control samples are collected at an offsite sample transect located offshore 8-10 miles west of the site. Available species are selected using the following guidelines:

1. A minimum of two species that are commercially or recreationally important are to be collected from each sample location. Samples selected are limited to edible and/or sport species when available.

2. Samples are composed of the edible portion only.

Selected fish samples are frozen immediately after collection and segregated by species and location. Samples are shipped frozen in insulated containers for analysis. Edible portions of each sample are analyzed for gamma emitting i:'adionuclides.

Fish sample locations are listed in Section 3.3, Table 3.3-1 and shown in Figure 3.3-5.

3 -13

3.1.3 SURFACE WATER Surface water samples are taken from the respective inlet canals of the JAFNPP and NRG's Oswego Steam Station. The JAFNPP facility draws water from Lake Ontario on a continuous basis. This is used for the "downstream" or indicator sampling point for the Nine Mile Point site. The Oswego Steam Station inlet canal removes water from Lake Ontario at a point approximately 7.6 miles west of the site. This "upstream" location is considered a control location because of the distance from the site, as well as the result of the lake current patterns and current patterns from the Oswego River located nearby.

Samples from the JAFNPP facility are composited from automatic sampling equipment which discharges into a compositing tank or bottles. Samples are collected monthly from the compositor and analyzed for gamma emitters. Samples from the Oswego Steam Station are also obtained using automatic sampling equipment and collected in a holding tank. Representative samples from this location are obtained weekly and are composited to form a monthly composite sample. The monthly samples are analyzed for gamma emitting radionuclides.

A portion of the monthly sample from each of the locations is saved and composited to form quarterly composite samples, which are analyzed for tritium.

In addition to the sample results for the JAFNPP and Oswego Steam Station collection sites, data is presented for the Nine Mile Point Unit 1 and Unit 2 facility inlet canal samples and from the City of Oswego drinking water supply. The latter three locations are not required by the ODCM. These locations are optional sample points, which are collected and analyzed to enhance the surface water sampling program. Monthly composite samples from these three locations are analyzed for gamma emitting nuclides, and quarterly composite samples are analyzed for tritium.

Surface water sample locations are listed in Section 3.3, Table 3.3-1 and shown on Figure 3.3-4.

3.1.4 AIR PARTICULATE I IODINE The air sampling stations required by the ODCM are located in the general area of the site boundary. The sampling stations are sited within a distance of 0.2 miles of the site boundary in sectors with the highest calculated deposition factor (D/Q) based on historical meteorological data. These stations (RI, R2, R3 and R4) are located in the E, ESE, and SE sectors as measured from the center of the Nine Mile Point Nuclear Station Unit 2 Reactor Building. The ODCM also requires that a fourth air sampling station be located in the vicinity of a year-round community. This station is located in the SE sector at a distance of 1.8 miles and is designated as Station R4. A fifth station required by the ODCM is a control location designated as Station R5. Station R5 is located I6.2 miles from the site in the NE meteorological sector.

In addition to the five ODCM required locations, there are ten additional sampling stations.

Six of these sampling stations are located within the site boundary and are designated as Onsite Stations DI, G, H, I, J, and K. These locations are within the site boundary of the NMPNS and JAFNPP. One air sampling station is located offsite in the southwest sector in the vicinity of the City of Oswego and is designated as Station G Offsite. Three remaining air sampling stations are located in the ESE, SSE, and SSW sectors and range in distance from 7.I to 9.0 miles. These are designated as Offsite Stations D2, E and F respectively.

Each station collects airborne particulates using glass fiber filters (47 millimeter diameter) and radioiodine using charcoal cartridges (2xI inch). The samplers run continuously and the charcoal cartridges and particulate filters are changed on a weekly basis. Sample volume is determined by use of calibrated gas flow meters located at the sample discharge.

Gross beta analysis is performed on each particulate filter. Charcoal cartridges are analyzed for radioiodine using gamma spectral analysis. The particulate filters are composited quarterly by location and analyzed for gamma emitting radionuclides.

Air sampling station locations are listed in Section 3.3, Table 3.3-I and shown on Figures 3.3-2 and 3.3-3.

3.1.5 TLD (DIRECT RADIATION)

Thermo luminescent dosimeters (TLDs) are used to measure direct radiation (gamma dose) in the environment. Environmental TLDs are supplied and processed quarterly by Stanford Dosimetry. The vendor utilizes a Panasonic based system using UD-814 dosimeters, which contain three CaS04 phosphor elements under 1OOOmg of lead and one lithium borate element.

1. Environmental TLDs Environmental TLDs are placed in five different geographical regions around site to evaluate effects of direct radiation as a result of plant operations. The following is a description of the five TLD geographical categories used in the NMPNS and JAFNPP Environmental Monitoring Program and the TLDs that make up each region:

TLD Geographical Category Description Onsite TLDs placed at various locations within the site boundary, with three exceptions, are not required by the ODCM. (TLD locations comprising this group are: 3, 4, 5, 6, 7*, 18*, 23*, 24, 25, 26, 27, 28, 29, 30, 31, 39, 47, 103, 106 and 107)

Site Boundary An inner ring of TLDs placed in the general area of the site boundary in each of the sixteen meteorological sectors. This category is required by the ODCM. (TLD locations comprising this group are: 7*, 18*, 23*, 75*, 76*, 77*, 78*, 79*, 80*, 81*,

82*, 83*, 84*, 85*, 86*, and 87*)

Offsite An outer ring of TLDs placed 4 to 5 miles from the site in each of the 8 land based meteorological sectors. This category is required by the ODCM. (TLD locations comprising this group are 88*,

89*, 90*, 91*,92*, 93*, 94*, and 95*)

Special Interest TLDs placed in special interest areas of high population density and use. These TLDs are located at or near large industrial sites, schools, or nearby towns or communities. This category is required by the ODCM. (TLD locations comprising this group are: 9, 10, 11, 12, 13, 15*, 19, 51, 52, 53, 54, 55, 56*, 58*, 96*,

97*,98*,99, 100, 101, 102, 108,and 109)

Control TLDs placed in areas beyond significant influence of the site and plant operations. These TLDs are located to the SW, S and NE of the site at distances of 12.5 to 24.7 miles. This category is also required by the ODCM. (TLD locations comprising this group are 8, 14*,49*, 111, 113)

TLD location required by the ODCM 3 -16

Although the ODCM requires a total of 32 TLD stations; environmental TLDs are also placed at additional locations not required by the ODCM, within the Onsite, Special Interest and Control TLD categories to supplement the ODCM required Direct Radiation readings.

Two dosimeters are placed at each TLD monitoring location. The TLDs are sealed in polyethylene packages to ensure dosimeter integrity and placed in open webbed plastic holders and attached to supporting structures, such as utility poles.

Environmental TLD locations are listed in Section 3.3, Table 3.3-1 and show on Figures 3.3-2 and 3.3-3.

2. Independent Spent Fuel Storage Installation (ISFSI)

In order to provide adequate spent fuel storage capacity at NMP 1 and NMP2, NMPNS constructed an ISFSI onsite west of NMPl. During 2012 the NMPNS ISFSI facility was placed into service.

TLDs are used to monitor direct radiation levels in the vicinity of the ISFSI facility. Sixteen (16) TLD locations were established around the site boundary. Background data has been collected from the initiation of the NMPNS REMP TLD program in 1985.

In addition, fourteen (14) Optically Stimulated Luminescence Dosimeters (OSDLs) are located around the ISFSI and in areas where personnel are assigned routine work activities.

These locations are designated as optional locations. Background data was collected starting in June, 2011.

REMP TLD locations are shown in Section 3.3, Table 3.3-1 and Figures 3.3-2 & 3.3-3.

3 -17

3.1.6 MILK Milk samples are routinely collected from farms during the sampling year. These farms include one indicator location and one control location. Samples are normally collected April through December of the sample year. If plant related radionuclides are detected in samples in November and December of the previous year, milk collections are continued into the following year starting in January. If plant related radionuclides are not detected in the November and December samples, then milk collections do not commence until April of the following sampling year. Milk samples were not collected in January through March of 2016 as there were no positive detections of plant related radionuclides in samples collected during November and December of2015.

The ODCM also requires that a sample be collected from a control location nine to twenty miles from the site and in a less prevalent wind direction. This location is in the south sector at a distance of 16 miles and serves as the control location.

Milk samples are collected in polyethylene bottles from a bulk storage tank at each sampled farm. . Before the sample is drawn, the tank contents are agitated to assure a homogenous mixture of milk and butter fat. The samples are chilled, preserved, and shipped fresh to the analytical laboratory within thirty-six hours of collection in insulated shipping containers.

The milk sample locations are listed in Section 3.3, Table 3.3-1 and shown on Figure 3.3-4.

3.1.7 FOOD PRODUCTS (VEGETATION)

Food products are collected once per year during the late summer harvest season. A minimum of three different ki.nds of broad leaf vegetation (edible or inedible) are collected from two different indicator garden locations. Sample locations are selected from available gardens identified in the annual census that have the highest estimated deposition values (D/Q) based on historical site meteorological data. Control samples are also collected from available locations greater than 9 .3 miles distance from the site in a less prevalent wind direction. Control samples are of the same or similar type of vegetation when available.

Food product samples are analyzed for gamma emitters using gamma isotopic analysis.

Food product locations are listed in Section 3.3, Table 3.3-1 and shown on Figure 3.3-5.

3.1.8 GROUND WATER MONITORING PROGRAM The Nuclear Energy Institute (NEI) Groundwater Protection Initiative was established to determine the potential impact nuclear power plants may have on the surrounding environment due to unplanned releases of radioactive liquids. Under the NEI 07-07.

Groundwater Protection Initiative (GPI) - Final Guidance Document, August 2007, groundwater monitoring is accomplished through sampling of the water table around the plant and analyzing for tritium. In addition to the groundwater monitoring requirements specified in the NMP2 ODCM, NMPNS started monitoring groundwater wells in October 2005 and has been monitoring the plant dewatering systems as part of the response to Generic Letter 80-10 for several years. Samples collected from these locations are analyzed for tritium, gamma emitters, and strontium.

Samples obtained from these wells are analyzed on a quarterly basis to determine gamma emitters and tritium concentrations. Ground water samples are analyzed for gamma emitters using gamma-spectrum analysis and tritium using liquid scintillation detector.

Groundwater tritium results are documented in the 2016 Annual Radiological Effluent Release Report.

Historical groundwater data is presented in Section 7, Historical Data Tables.

Groundwater sample locations are shown in Section 3.3, Figure 3.3-6.

3.2 ANALYSES PERFORMED Environmental sample analyses are performed at the JAFNPP Chemistry Laboratory or by a contract laboratory. The following analyses were performed:

1. Air Particulate Filter - Gross Beta

2. Air Particulate Filter Composites - Gamma Spectral Analysis

3. Airborne Radioiodine - Gamma Spectral Analysis

3.4 LAND USE CENSUS The ODCM requires that a milch animal census and a residence census be conducted annually out to a distance of five miles. Milch animals are defined as any animal that is routinely used to provide milk for human consumption.

The milch animal census is an estimation of the number of cows and goats within an approximate ten mile radius of the Nine Mile Point site. The census is done once per year in the summer. It is conducted by sending questionnaires to previous milch animal owners, and by road surveys to locate any possible new owners. In the event that questionnaires are not answer~d, the owners are contacted by telephone or in person. The Oswego County Cooperative Extension Service was also contacted to provide any additional information.

The residence census is conducted each year to identify the closest residence in each of the 22.5 degree meteorological sectors out to a distance of five miles. A residence, for the purposes of this census, is a residence that is occupied on a part time basis (such as a summer camp), or on a full time, year round basis. Eight of the site meteorological sectors are over Lake Ontario; therefore, there are only eight sectors over land where residences are located within five miles.

In addition to the milch animal and residence census, a garden census was performed for the 2016 growing season. The census is conducted each year to identify the gardens nearest the site, within a 5 mile radius, that are to be used for the collection of food product samples.

3.5 CHANGES TO THE REMP PROGRAM Based upon the results of the 2016 Land Use Census, there were no. changes to the 2016 sampling program.

3.6* DEVIATION AND EXCEPTIONS TO THE PROGRAM The noted exceptions to the 2016 sample program address only those samples or monitoring requirements which are required by the ODCM. This section satisfies the reporting requirements of Section D 6.9.1.d of the NMPl ODCM and Section D 4.1.2 of the NMP2 ODCM.

3 - 32

3.6.1 ODCM Program Deviations The following are deviations from the program specified by the ODCM:

1. 03/24/16 - 03/29/16 Air Station R2 Offsite sample pump was inoperable for approximately 126 hours0.00146 days 0.035 hours 2.083333e-4 weeks 4.7943e-5 months . Out of service time was determined based upon- sample pump run time integrator. The inoperability was due to loss of power to the sample station. No corrective actions were required to restore power to the station. (AR 02647640 stated alternate power supply was used to provide power and follow up requested on breaker and switch)

2. 07/18/16 - 07/26/16 Air Stations Rl, R2, R3, R4 and RS Offsite samples were not shipped in a timely manner. The 1-131 concentration was not determined within the

. one week requirement. Vendor Laboratory received samples on 08/03/16 and all samples met the required Lower Limit of Detection (LLD) for 1-131.

3. 10/29/16 - 11/01/16 Air Station Rl Offsite sample pump was inoperable for approximately 61 hours7.060185e-4 days 0.0169 hours 1.008598e-4 weeks 2.32105e-5 months . Out of service time was determined based upon sample pump run time integrator. The inoperability was due to sample pump overheating when installed cabinet cooling fan failed. Sample pump and the cooling fan were replaced.

4. 10/25/16 - 11/01/16 Air Station R4 Offsite particulate filter was found misaligned in filter housing resulting in partial sample collection for approximately 168 hrs.

Technician installing particulate filter validated position as procedure requires.

Cabinet cooling fan was not operating during the 10/25/16 particulate filter change.

Maintenance replaced the cabinet cooling fan later that day. Turning the sample pump on and off, to support fan replacement, may have disturbed the particulate filter positioning.

3.6.2 Air Sampling Station Operability Assessment The ODCM required air sampling program consists of 5 individual sampling locations.

The collective operable time period for the air monitoring stations was 43, 733 hours0.00848 days 0.204 hours 0.00121 weeks 2.789065e-4 months out of a possible 43,920 hours0.0106 days 0.256 hours 0.00152 weeks 3.5006e-4 months . The air sampling availability factor for the report period was 99.6%.

Air sampling equipment found inoperable was returned to service. Identification of locations for obtaining replacement samples was not required.*

3.7 'STATISTICAL METHODOLOGY There are a number of statistical calculation methodologies used in evaluating the data from the environmental monitoring program. These methodologies include determination of standard deviation, the mean and associated error for the !llean, and the lower limit of detection (LLD).

3.7.1 ESTIMATION OF THE MEAN AND STANDARD DEVIATION The mean (X) and standard deviation(s) were used in the reduction of the data generated by the sampling and analysis of the various media in the JAFNPP Radiological Environmental Monitoring Program (REMP). The following equations were utilized to compute the mean (X) andthe standard deviation(s):

1. Mean n

x L xi i =1 N

Where, x = estimate of the mean 1 = individual sample N, n = total number of samples with positive indications xi = value for sample i above the lower limit of detection.

2. Standard Deviation 1/2 S=

(N-1)

Where, x = mean for the values of X s = standard deviation for the sample population 3 - 34

3.7.2 ESTIMATION OF THE MEAN & THE ESTIMATED ERROR FOR THE MEAN In accordance with program policy, when the initial count indicates the presence of a plant related radionuclide(s) in a sample, two recounts of the sample may be required. When a radionuclide is positively identified in two or more counts, the analytical result for the radionuclide is reported as the mean of the positive detections and the associated propagated error for that mean. In cases where more than one positive sample result exists, the mean of the sample results and the estimated error for the mean are reported in the Annual Report.

The following equations were utilized to estimate the mean (X) and the associated propagated error.

1. Mean n

I X*l i = 1 N

Where, x = estimate of the mean 1 = individual sample N,n = total number of samples with positive indications xi = value for sample i above the lower limit of detection

2. Error of the Mean 11 2 ERROR MEAN = [ £ i=l (ERROR. )

2

]

N Where, ERROR MEAN = propagated error

= individual sample ERROR = 1 sigma* error of the individual analysis N,n = number of samples with positive indications

Sigma (cr)

Sigma is the Greek letter used to represent the mathematical term Standard Deviation.

Standard Deviation is a measure of dispersion from the arithmetic mean of a set of numbers.

3 - 35

3.7.3 LOWER LIMIT OF DETECTION (LLD)

The LLD is the predetermined concentration or activity level used to establish a detection limit for the analytical procedures.

The LLDs are specified by the ODCM for radionuclides in specific media and are determined by taking into account the overall measurement methods. The equation used to calculate the LLD is:

LLD= 4.66 Sb (E) (V) (2.22) (Y) exp (-A.lit)

Where:

LLD = the a priori lower limit of detection, as defined above (in picocuries per unit mass or volume)

Sb the standard deviation of the background counting rate or of the counting rate of a blank sample, as appropriate (in counts per minute)

E = the counting efficiency(in counts per disintegration)

V the sample size (in units of mass or volume) 2.22 = the number of disintegrations per minute per picocurie Y the fractional radiochemical yield (when applicable)

/.., the radioactive decay constant for the particular radionuclide lit the elapsed time between sample collection (or end of the sample collection period) and time of counting The ODCM LLD formula assumes that:

1. The counting times for the sample and background are equal

2. The count rate of the background is approximately equal to the count rate of the sample In the ODCM program, LLDs are used to ensure that minimum acceptable detection capabilities are met with specified statistical confidence levels (95% detection probability with 5% probability of a false negative). Table 3.8-1 lists the ODCM program required LLDs for specific media and radionuclides as specified by the NRC. The LLDs actually achieved are routinely lower than those specified by the ODCM.

3 - 36.

3.8 COMPLIANCE WITH REQUIRED LOWER LIMITS OF DETECTION (LLD)

Tables D 4.6.20-1 and D 3.5.1-3 of the NMPl ODCM and NMP2 ODCM, respectively, specify the detection capabilities for environmental sample analysis (See Table 3.8-1). The reporting requirements ofNMPl ODCM, Section D 6.9.1.d and NMP2 ODCM, Section D 4.1.2 require that a discussion of all analyses for which the_ LLDs required by Tables D 4.6.20-1 and D 3.5.1-3 were not achieved be included in the Annual Radiological Environmental Operating Report. This Section is provided pursuant to this requirement.

3.8.1 All sample analyses performed in 2016, as required by the ODCM, achieved the LLD specified by ODCM Tables D 4.6.20-1 and D 3.5.1-3.

3.9 REGULATORY LIMITS Two federal agencies, the Nuclear Regulatory Commission and Environmental Protection Agency, have responsibility for regulations promulgated for protecting the public from radiation and radioactivity beyond the site boundary.

3.9.1 The Nuclear Regulatory Commission (NRC):

The NRC, in 10 CPR 20.1301, limits the levels of radiation in unrestricted areas resulting from the possession or use of radioactive materials such that they limit any individual to a dose of:

less than or equal to 100 mrem per year to the total body In addition to this dose limit, the NRC has established design objectives for nuclear plant licensees. Conformance to these guidelines ensures that nuclear power reactor effluents are maintained as far below the legal limits as is reasonably achievable.

The NRC, in 10CFR 50, Appendix I, establishes design objectives for the dose to a member of the general public from radioactive material in liquid effluents released to unrestricted areas to be limited to:

less than or equal to 3 mrem per year to the total body, or

less than or equal to 10 mrem per year to any organ.

The air dose due to release of Noble gases in gaseous effluents is restricted to:

less than or equal to 10 mrad per year for gamma radiation, or

less than or equal to 20 mrad per year for beta radiation.

The dose to a member of the general public from Iodine-131, tritium,_and all particulate radionuclide's with half-lives greater than 8 days in gaseous effluents is limited to:

less than or equal to 15 mrem per year to any organ.

3 - 39

The NRC, in 10 CFR 72.104(a), establishes criteria for radioactive materials in effluents and direct radiation from an Independent Spent Fuel Storage Installation (ISFSI).

During normal operations and anticipated occurrences, the annual dose equivalent to any real individual who is located beyond the controlled area must not exceed:

25 mrem per year to the total body,

75 mrem per year to the thyroid, and

25 mrem per year to any other organ as a result of :

1. Planned discharges of radioactive material, radon and its decay products excepted, to the environment

2. Direct radiation from ISFSI

3. Any other radiation from uranium fuel cycle operations in the region 3.9.2 Environmental Protection Agency (EPA)

The EPA, in 40CFR190.10, Subpart B, sets forth the environmental standards for the uranium fuel cycle. During normal operation, the annual dose to any member of the public from the entire uranium fuel cycle shall be limited to:

less than or equal to 25 mrem per year to the total body,

less than or equal to 75 mrem per year to the thyroid, and

less than or equal to 25 mrem per year to any other organ.

TABLE NOTES:

Data for Table 4.0-1 is based on NMPl and NMP2 ODCM required samples unless otherwise indicated.

(a) LLD values as required by the ODCM. LLD units are specified in the medium column.

(b) Fraction of number of detectable measurements to total number of measurements. Mean and range results are based on detectable measurements only.

(c) Location is distance in miles and direction in compass degrees based on NMP2 reactor center-line. Units in this column are specified in medium column.

(d) Data includes results from optional samples in addition to samples required by the ODCM.

(e) The ODCM specify an I-131 and tritium LLD value for surface water analysis (non-drinking water) of 15 pCi/liter and 3000 pCi/liter respectively.

(t) The ODCM does not specify a particular LLD value for environmental TLDs. The NMPl and NMP2 ODCM contain specifications for environmental TLD sensitivities.

(g) Indicator TLD locations are: #7, 15, 18, 23, 56, 58, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, and 98.

Control TLDs are all TLDs located beyond the influence of the site (TLD #14 and 49).

(h) This dose is not representative of doses to a member of the public since this area is located near the north shoreline, which is in close proximity to the generating facility and is not accessible to members of the public (See Section 5.2.4, TLDs).

(i) The ODCM criteria for indicator milk sample locations include locations within 5.0 miles of the site. There are no milk sample locations within 5.0 miles of the site. Therefore, the only sample location required by the ODCM is the control location. There was one optional location during 2016.

5.0 DATA EVALUATION AND DISCUSSION Introduction Each year the results of the annual Radiological Environmental Monitoring Program (REMP) are evaluated considering plant operations at the site, the natural processes in the environment, and the archive of historical environmental radiological data. A number of factors are considered in the course of evaluating and interpreting the annual environmental radiological data. This interpretation can be made using several methods including trend analysis, population dose estimates, risk estimates to the general population based on significance of environmental concentrations, effectiveness of plant effluent controls, and specific research areas. The report not only presents the data collected during the 2016 sample program but also assesses the significance of radionuclides detected in the environment. It is important to note that detection of a radionuclide is not, of itself, an indication of environmental significance. Evaluation of the impact of the radionuclide in terms of potential increased dose to man, in relation to natural background, is necessary to determine the true significance of any detection.

Units of Measure Some of the units of measure used in this report are explained below.

Radioactivity is the number of atoms in a material that decay per unit of time. Each time an atom decays, radiation is emitted. The curie (Ci) is the unit used to describe the activity of a material and indicates the rate at which the atoms are decaying. One curie of activity indicates the decay of 37 billion atoms per second.

The mass, or weight, of radioactive material that would result in one curie of activity depends on the disintegration rate or half-life. For example, one gram of radium-226 contains one curie of activity, but it would require about 1.5 million grams of natural uranium to equal one curie. Radium-226 is more radioactive than natural uranium on a weight or mass basis.

Smaller units of the curie are used in this report. Two common units are the microcurie

(µCi), which is one millionth (0.000001) of a curie, and the picocurie (pCi), which is one trillionth (0.000000000001) of a curie. The picocurie (pCi) is the unit of radiation that is routinely used in this report.

Dose/Dose to Man The dose or dose equivalent, simply put, is the amount of ionizing energy deposited or absorbed in living tissue. The amount of energy deposited or ionization caused is dependent on the type of radiation. For example, alpha radiation can cause dense localized ionization that can be up to 20 times the amount of ionization for the same energy imparted as from gamma or x-rays. Therefore, a quality factor must be applied to account for the different ionizing capabilities of various types of radiation. When the quality factor is multiplied by the absorbed dose, the result is the dose equivalent, which is an estimate of 5-1

the possible biological damage resulting from exposure to any type of ionizing radiation. The dose equivalent is measured in rem (roentgen equivalent man). In terms of environmental radiation, the rem is a large unit. Therefore, a smaller unit, the millirem (mrem) is often used. One millirem (mrem) is equal to 0.001 of a rem.

The term "dose to man" refers to the dose or dose equivalent that is received by members of the general public at or beyond the site boundary. The dose is calculated based on concentrations of radioactive material measured in the environment. The primary pathways that contribute to the dose to man are; the inhalation pathway, the ingestion pathway, and direct radiation.

Discussion In the United States, a person' s average annual radiation dose is 620 mrem. About half that amount comes from naturally occurring radionuclides. Radon and thoron gases account for two- thirds of this exposure, while cosmic, terrestrial, and internal radiation account for the remainder. The other half comes from manmade sources and is mostly from diagnostic medical procedures.

The pie chart below shows a breakdown of radiation sources that contribute to the average annual U.S. radiation dose of 620 mrem. Nearly three-fourths of this dose is split between radon/thoron gas (naturally occurring) and diagnostic medical procedures (manmade ).

There are three separate groups of radionuclides that were measured and analyzed for in the 2016 environmental sampling program.

1. The first of these groups consists of the radionuclides that are naturally occurring. The environment contains a significant inventory of naturally occurring radioactive elements.

The components of natural or background radiation include the decay of radioactive elements in the earth's crust, a steady stream of high-energy particles from space called cosmic radiation and naturally-occurring radioactive isotopes in the human body like potassium-40.

A number of naturally occurring radionuclides are present in the environment. These are expected to be present in many of the environmental samples collected in the vicinity of the Nine Mile Point Site. Some of the radionuclides normally present include:

Beryllium- 7, present as a result of the interaction of cosmic radiation with the upper atmosphere

Potassium-40 and Radium-226, naturally occurring radionuclides found in the human body and throughout the environment Beryllium-7 and Potassium-40 are especially common in REMP samples. Since they are naturally occurring and are abundant, positive results for these radionuclides are reported in some cases in Section 6.0 of this report. Comparisons of program samples to naturally occurring radiation are made throughout this section to help put program results into perspective and to aid the reader in determining what, if any, significant impact is demonstrated by the REMP results .

2. The second group consists of radionuclides that may be detected in the environment as a result of the detonation of thermonuclear devices in the earth' s atmosphere. Atmospheric nuclear testing during the early 1950' s produced a measurable inventory of radionuclides presently found in the lower atmosphere, as well as in ecological systems. In 1963, an Atmospheric Test Ban Treaty was signed. Since the treaty, the global inventory of manmade radioactivity in the environment has been greatly reduced through the decay of short lived radionuclides and the removal of radionuclides from the food chain by such natural processes as weathering and sedimentation. This process is referred to in this report as ecological cycling. Since 1963 , several atmospheric weapons tests have been conducted by the People' s Republic of China and undergrourid weapons testing by India, Pakistan & North Korea. In some cases, the usual radionuclides associated with nuclear detonations were detected for several months following the test, and then after a peak detection period, diminished to a point where most could not be detected.

Although reduced in frequency, atmospheric testing continued into the 1980's. The resulting fallout or deposition from these most recent tests has influenced the background radiation in the vicinity of the site and was evident in many of the sample media analyzed over the years. Fallout radionuclides from nuclear weapons testing included Cesium-137 and Strontium-90. The highest weapons testing concentrations were noted in samples collected for the 1981 REMP . Cs-137 was the major byproduct of this testing and is still occasionally detected in a few select number of environmental media.

3. The third group consists of radionuclides that may be detected in the environment are 5-3

related to nuclear power technology. These radionuclides are the byproduct of the operation of light water reactors. These byproduct radionuclides, the same as those produced in atmospheric weapons testing, are found in the Chernobyl and Fukushima Daiichi Nuclear Power Station fallout. This commonality makes a determination of the source of these radionuclides, which may be detected in environmental samples, difficult.

During 2016, there were no plant-related radionuclides detected in the REMP sampling.

A number of factors must be considered in performing radiological sample data evaluation and interpretation. The evaluation is made using several approaches including trend analysis and dose to man. An attempt has been made not only to report the data collected during 2016, but also to assess the significance of the radionuclides detected in the environment as compared to naturally occurring and manmade radiation sources. It is important to note that detected concentrations of radionuclides in the local environment as a result of man' s technology are very small and are of no, or little, significance from an environmental or dose to man perspective.

The 2009 per capita average dose was determined to be 620 rnrem per year from all sources, as noted in National Council on Radiation Protection and Measurement (NCRP) Report No. 160. This average dose includes such exposure sources as industrial &

occupational, consumer products, terrestrial, cosmic, internal, nuclear medicine, medical procedures, radon and thoron. The 2009 per capita dose rate due to naturally occurring sources was 310 rnrem per year. The per capita radiation dose from nuclear power production nationwide is less than 1 rnrem per year.

The naturally occurring gamma radiation in the environs of the Nine Mile Point site, resulting from radionuclides in the atmosphere and in the ground, accounts for approximately 50 rnrem per year. This dose is a result of radionuclides of cosmic origin (for example, Be-7) and of primordial origin (Ra-226, K-40, and Th-232). A dose of 47 rnrem per year, as a background dose, is significantly greater than any possible doses as a result of routine operations at the site during 2016.

The results of each sample medium are discussed in detail in Sections 5.1 and 5.2. This includes a summary of the results, the estimated environmental impact, a detailed review of any relevant findings with a dose to man estimate where appropriate, and an analysis of possible long-term and short-term trends.

During routine implementation of the REMP, additional or optional environmental pathway media are sampled and analyzed. These samples are obtained to:

Expand the area covered by the program beyond that required by the ODCM,

Provide more comprehensive monitoring than is currently required,

Monitor the secondary dose to man pathways, and

Maintain the analytical data base established when the plants began commercial operation.

5-4

The optional samples that are collected will vary from year to year. In addition to the optional sample media, additional locations are sampled and analyzed for those pathways required by the ODCM. These additional sample locations are obtained to ensure that a variety of environmental pathways are monitored in a comprehensive manner. Data from additional sample locations that are associated with the required ODCM sample media are included in the data presentation and evaluation. When additional locations are included, the use of this data is specifically noted in Sections 5.1 and 5.2.

Section 6.0 contains the analytical results for the sample media addressed in the report. Tables are provided for each required sample medium analyzed during the 2016 program.

Section 7.0, titled Historical Data Tables, contains statistics from previous years' environmental sampling. The process of determining the impact of plant operation on the environment includes the evaluation of past analytical data to determine if trends are changing or developing. As state-of-the-art detection capabilities improve, data comparison is difficult in some cases. For example, Lower Limits of Detections (LLDs) have improved significantly since 1969 due to technological advances in laboratory procedures and analytical equipment.

5.1 AQUATIC PROGRAM The aquatic program consists of samples collected from three environmental pathways. These pathways are:

Shoreline Sediment

Fish

Surface Waters Section 6.0, Tables 6-1 through 6-4 present the analytical results for the aquatic samples collected for the 2016 sampling period.

5.1.1 SHORELINE SEDIMENT RESULTS A. Results Summary Shoreline sediment samples were obtained in April and October of 2016 at one offsite control location (Lang' s Beach located near Oswego Harbor) and at one indicator location (Sunset Bay) which is an area east of the site considered to have recreational value.

A total of four sediment samples were collected for the 2016 sample program, two indicator and two control. Cs-13 7 was not detected in samples collected from the Sunset Bay indicator location or the Lang' s Beach control location during 2016. No plant-related radionuclides were detected in the 2016 shoreline sediment samples.

The following is a graph of the average Cs-13 7 concentration in shoreline sediment samples over 20 years. This graph illustrates a general downward trend in the Cs-13 7 concentrations since 1995 . No Cs-137 has been detected in shoreline sediment samples since 5-5

2007.

0 B. Data Evaluation and Discussion Shoreline sediment samples are routinely collected twice per year from the shoreline of Lake Ontario. Samples are collected from one indicator location (Sunset Bay), and one control location (Lang's Beach). Samples were collected from both the indicator and control locations in April and October 2016. The results of these sample collections are presented in Section 6.0, Table 6-1 , "Concentrations of Gamma Emitters in Shoreline Sediment Samples - 2016". Potassium-40 (K-40) and Radium-226 (Ra-226), Thorium-228 (Th-228) and Thorium-232 (Th-232) all naturally-occurring isotopes, were the only radionuclides detected in the sediment samples.

C. Dose Evaluation The calculated potential whole body and skin doses which may result from the measured Cs-137 concentrations in previous years are extremely small and are insignificant when compared to natural background doses.

The radiological impact of Cs-137 measured in the shoreline sediment can be evaluated on the basis of dose to man. In the case of shoreline sediments, the critical pathway is direct radiation to the whole body and skin. Using the parameters provided in Regulatory Guide 1.109, the potential dose to man in mrem per year can be calculated. The following regulatory guide values were used in calculating the dose to man:

A teenager spends 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months per year at the beach area or on the shoreline,

The sediment has a mass of 40 kglm2 (dry) to a depth of 2.5 cm,

The shoreline width factor is 0.3 , and

The maximum 2016 LLD concentration of <0.084 pCi/g (dry).

5-6

Using these conservative parameters, the potential dose to the maximwn exposed individual (teenager) would be 0.00028 mrem per year to the whole body and 0.00033 mrem per year to the skin. This calculated dose is very small and is insignificant when compared to the natural background annual exposure of approximately 47 mrem as measured by control TLDs in the vicinity of the site.

D. Data Trends Cs-13 7 was not detected at the indicator and control sample locations from 2008 through 2016.

The general absence of Cs-137 in the indicator and control samples can be attributed to changing lake levels and shoreline erosion. Recent soil samples, from locations beyond any expected influence from the site, have contained levels of Cs-137 equal to or greater than the concentrations found in shoreline samples collected in the past. Cs-13 7 is commonly found in soil samples and is attributed to weapons testing fallout.

The previous ten year data trend for indicator shoreline samples showed an overall downward trend in concentration measured at the indicator sample locations. Over the previous ten year period maximum concentration at the indicator location was 0.04 pCi/g (dry) in 2007. Cs-13 7 was not detected at the indicator location for 2008 through 2016. This continues to support the long term decreasing trend in Cs-13 7 concentration in shoreline sediment samples. Cs-137 was not detected in the control samples collected over the previous ten years.

Shoreline sediment sampling at the indicator location commenced in 1985. Prior to 1985, no data was available for long term trend analysis.

Section 7.0, Tables 7-1 and 7-2 illustrate historical environmental data for shoreline sediment samples.

5.1.2 FISH SAMPLE RESULTS A. Results Summary A total of 18 fish samples were collected for the 2016 sample program. The analytical results for the 2016 fish samples showed no detectable concentration of radionuclide that would be attributable to plant operations at the site or past atmospheric weapons testing. Since 2003 , no Cs-137 has been measured in fish samples. Over the previous 20 years prior to 2003 , Cs-137 has been detected at a combination of both the indicator and/or control locations. (Refer to Tables 7-3 and 7-4). These low levels of Cs-137 represented no significant dose to man or impact on the environment.

The 2016 fish sample results demonstrate that plant operations at the Nine Mile Point Site have no measurable radiological environmental impact on the upper levels of the Lake Ontario food 5-7

chain. The 2016 results are consistent with previous year' s results in that they continue to support the general long-term downward trend in fish Cs-137 concentrations over the last 25 years. Cs-13 7 was not detected in fish samples collected from 2003 to 2016 at indicator locations.

B. Data Evaluation and Discussion Fish collections were made utilizing gill nets at one location greater than five miles from the site (Oswego Harbor area) and at two locations in the vicinity of the lake discharges for the NMPNS and the JAFNPP facilities. The Oswego Harbor samples served as control samples while the NMPNS and JAFNPP samples served as indicator samples. All samples were analyzed for gamma emitters. Section 6.0, Table 6-2 shows individual results for all the samples collected in 2016 in units of pCi/g (wet).

The spring fish collection was made up of 9 individual samples representing three separate species. Brown Trout, Smallmouth Bass, and Walleye were collected.

The fall fish collection was comprised of 9 individual samples representing three individual species. Chinook Salmon, Smallmouth Bass and Walleye were collected. Due to the inability to gill net walleye a second independent sample of Chinook Salmon was used . Results recorded in Table 6-2 labeled sample results as Chinook Salmon 1 and Chinook Salmon2

C. Dose Evaluation Fish represent the highest level in the aquatic food chain and have the potential to be a contributor to the dose to man from the operations at the site. The lack of detectable concentrations of plant-related radionuclides in the 2016 fish samples demonstrates that there is no dose to man attributable from operations at the site through the aquatic pathway. Some Lake Ontario fish species may be considered an important food source due to the local sport fishing industry. Therefore, these fish are an integral part of the human food chain.

D. Data Trends The positive detection of Cs-13 7 in fish samples ceased in 2003. The graph below illustrates the mean control and indicator Cs-13 7 concentrations for 2016 and the previous fourteen years.

The concentrations of Cs-13 7 detected in fish since 197 6 are considered to be the result of weapons testing fallout. The general downward trend in concentrations will continue as a function of additional ecological cycling and radiological decay.

The data trend shows a consistent level of Cs-13 7 measured in fish between 1997 and 1998. After 1998, the number of positive detections drops off as noted in the five year trend. The 1995 through 2016 results, as a group, are the lowest Cs-13 7 concentrations measured over the existence of the sample program.

5.1.3 SURFACE WATER (LAKE)

A. Results Summary The ODCM requires that monthly surface water samples be taken from the respective inlet water supplies of the JAFNPP and NRG Energy's Oswego Steam Station. In conjunction with the required samples, three additional Lake Ontario surface water locations are sampled and analyzed. These additional locations are the Oswego City Water Intake, the NMPl Intake and the NMP2 Intake. Gamma spectral analysis was performed on 24 monthly composite samples from the ODCM locations and on 36 monthly composite samples collected from the additional sample locations. The results of the gamma spectral analyses showed that only naturally-occurring radionuclides were detected in the 60 samples from the five locations collected for the 2016 Sampling Program. Monthly composite samples showed no presence of plant-related gamma emitting isotopes in the waters of Lake Ontario as a result of plant operations.

The monthly surface water samples are composited on a quarterly basis and are analyzed for tritium. A total of20 samples were analyzed for tritium as part of the 2016 REMP program. The results for the 2016 samples showed no positive detection of tritium above 500 pCi/L.

B. Data Evaluation and Discussion Gamma spectral analysis was performed on monthly composite samples from five Lake Ontario sampling locations. No plant-related radionuclides were detected in 2016 samples. This is consistent with historical data, which has not shown the presence of plant-related radionuclides in surface water samples.

The tritium results for the JAFNPP inlet canal samples contained no positive detections. The .2016 results had LLD values that ranged from <336 pCi/l to <477 pCi/l. The ODCM Control location (Oswego Steam Station inlet canal) results showed no positive detections and the sample results had LLD values in the range of <191 pCi/l to <473 pCi/l.

Tritium was not detected in any of the twelve optional Lake Ontario samples collected in the 2016 program.

The Oswego Steam Inlet is sampled to monitor drinking water quality and is representative of a control location due to its distance from the site. The city water inlet is located 7.6 miles west of the site in an "upstream" direction based on the current patterns in the lake.

5 - 10

The following is a summary of LLD results for the 2016 sample program:

Sample Tritium Concentration (pCi/liter)

Location Minimum Maximum Mean (Annual)

JAF Inlet (Indicator)* <336 <477 <399 Oswego Steam Inlet (Control)* <191 <473 <363 NMP #1 Inlet <190 <474 <360 NMP #2 Inlet <188 <464 <359 Oswego City Water Supply <186 <471 <358

Sample location required by ODCM The above LLD values are below the ODCM required LLD value of 3000 pCi/l. Analytical results for surface water samples are found in Section 6.0, Tables 6-3 through 6-4.

C. Dose Evaluation The radiological impact to members of the public from low levels of tritium in water is insignificant. This can be illustrated by calculating a dose to the whole body and maximum organ using the maximum LLD value and Regulatory Guide 1.109 methodology. Based on a water ingestion rate of 510 liters/yr and a maximum LLD concentration of <4 77 pCi/l, the calculated dose would be less than 0.049 mrem per year to the child whole body and less than 0.049 mrem per ye a r to the child liver (critical age group/organ).

D. Data Trends There are no data trends for gamma emitters such as Cs-13 7 and Co-60 as historically these radionuclides have not been detected in lake water samples.

Tritium results for the 2016 lake water samples were consistent with results from the previous five years for both the indicator and control locations. The mean 2016 tritium concentrations were <363 pCi/l for the control and <399 pCi/l for the indicator location. For the previous five years, there were no positive detections for the indicator and control locations. This previous five year data set is consistent with long term tritium results measured at the site. The indicator data from the previous ten year period, 2007 . through 2016, tritium concentrations show no detectable levels of tritium measured. The 1999 mean control value of 365 pCi/l is the highest concentration measured since 1987 and is within the variability of results measured over the life of the program.

The following graph illustrates the concentrations of tritium measured in Lake Ontario over the previous 20 years at both an indicator and control location. Prior to 1985, the Oswego City Water Supply results were used as control location data as this location closely approximates the Oswego Steam Station, the current control location. There is no existing preoperational data for comparison to recent data.

5.1.4 GROUNDWATER A. Results Summary A groundwater monitoring program is not required by the ODCM. The program is being implemented as the result of Nuclear Energy Institue (NEI) Ground Water Protection Initiative.

Groundwater samples were collected from a number of locations shown in Section 3.3, Figure 3.3-6 and listed in Table 3.3-1.

A total of 116 tritium samples were collected for the 2016 sample program using twenty five indicator locations and three control locations.

A total of nineteen monitoring well samples were collected for plant-related gamma-emitters, and seventeen monitoring well samples were collected for strontium-89/90 (Sr-89 and Sr-90) during the 2016 sample program using twenty five indicator locations and three control locations. All sample results for 2016 groundwater monitoring program were less than the LLD for plant-related gamma-emitters and strontium 89/90.

5 - 12

B. Data Evaluation and Discussion Plant related gamma-emitters and strontium-89/90 analysis were performed on samples from the indicator and control locations. No plant-related radionuclides were detected in the 2016 samples.

This is consistent with historical data, which has not shown the presence of plant-related radionuclides in groundwater samples.

Monitoring well tritium samples analyzed for the 2016 sample program were analyzed to an LLD of 200 pCi/l. The tritium results for the control locations and indicator locations ranged from <108 to 749 pCi/l.

The NMP2 storm drain system indicator location results ranged from <147 to 201 pCi/l tritium.

C. Dose Evaluation Sampling for groundwater, as found in Section D 3.5.l of the NMP2 ODCM, was not required during 2016. There were no groundwater sources in 2016 that were tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties support contaminant migration; therefore, drinking water was not a dose pathway during 2016.

To assess the dose associated with tritium, the highest value was used :

Maximum tritium concentration 749 pCi/l (highest value)

510 liters of water consumed per year.

The theoretical dose to the whole body and maximum organ using the maximum value and Regulatory Guide 1.109 methodology were determined. The calculated dose would be 0.078 rnrem to the child whole body and 0.078 rnrem to the child liver (critical age group/organ).

D. Data Trends There are no data trends for gamma-emitters or Strontium-89/90 as these radionuclides have not been detected in groundwater samples.

Groundwater tritium results are documented in the Annual Radiological Effluent Release Report for 2016. Historical data for groundwater tritium is presented in Section 7.0, Table 7-25, Historical Environmental Sample Data, Groundwater Tritium (Control), Table 7-26, Historical Environmental Sample Data, Groundwater Monitoring Wells Tritium (Indicator) and Table 7-27, Historical Environmental Sample Data, NMP2 Storm Drain Tritium (Indicator).

5.2 TERRESTRIAL PROGRAM The terrestrial program consists of samples collected from four environmental pathways. These pathways are:

Airborne particulate and radioiodine

Direct Radiation

Milk

Food Products Section 6.0, Tables 6-5 through 6-12 present the analytical results for the terrestrial samples collected for the 2016 reporting period.

5.2.1 AIR PARTICULATE GROSS BET A A. Results Summary Weekly air samples were collected and analyzed for particulate gross beta activity. For the 2016 program, a total of 53 samples were collected from control location R5 and 212 samples were collected from indicator locations Rl , R2, R3 , and R4. These five locations are required by the ODCM. Additional air sampling locations are maintained and are discussed in Section 5.2.1.B below. The mean gross beta concentration for samples collected from the control location (R5) in 2016 was 0.014 pCi/m3. The mean gross beta concentration for the samples collected from the indicator locations (Rl , R2, R3 , and R4) in 2016 was 0.015 pCi!m3. The consistency between the indicator and control mean values, demonstrates that there are no increased airborne radioactivity levels in the general vicinity of the site from plant effluents.

B. Data Evaluation and Discussion The air monitoring system consists of fifteen sample locations, six onsite and nine offsite. Each location is sampled weekly for particulate gross beta activity. A total of 795 samples were collected and analyzed as part of the 2016 program. In addition, optional offsite and onsite air sample locations are maintained from which weekly samples are collected.

The optional offsite locations are designated as D2, E, F and G. The optional onsite locations are designated as Dl , G, H, I, J and K.

Gross beta analysis requires that the samples be counted no sooner than 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months after collection.

This allows for the decay of short half-life naturally-occurring radionuclides, thereby increasing the sensitivity of the analysis for plant-related radionuclides.

Section 6.0, Tables 6-5 and 6-6 present the weekly gross beta activity results for samples collected from the offsite and onsite locations.

The minimum, maximum and average gross beta results for sample locations required by the ODCM were as follows:

The fluctuations observed in the gross beta activity over the year can be attributed to changes in the environment, especially seasonal changes. The concentrations of naturally-occurring radionuclides in the lower levels of the atmosphere directly above the land are affected by time-related processes such as wind direction, precipitation, snow cover, soil temperature and soil moisture content.

C. Dose Evaluation Dose calculations are not performed based on gross beta concentrations. Dose to man as a result of radioactivity in air is calculated using the specific radionuclide and the associated dose factor.

See Section 5.2.2.C for dose calculations from air concentrations. The dose received by man from air gross beta concentration is a component of the natural background.

D. Data Trends With the exception of the 1986 sample data, which was affected by the Chernobyl accident, the general trend in air particulate gross beta activity has been one of decreasing activity since 1981, when the mean control value was 0.165 pCi/m 3. The 1981 samples were affected by fallout from a Chinese atmospheric nuclear test which was carried out in 1980.

The mean gross beta concentration measured in 1969 to 2016 are illustrated in the following graph:

5.2.2 QUARTERLY PARTICULATE COMPOSITES (GAMMA EMITTERS)

A. Results Summary Fifteen air monitoring stations are maintained around the Nine Mile Point Site. Five of the 15 air monitoring stations are required by the ODCM and are located offsite near the site boundary and offsite as a control location. Ten additional air sampling stations are also maintained as part of the sampling program. Together, these fifteen continuous air sampling stations make up a comprehensive environmental monitoring network for measuring radioactive air particulate concentrations in the environs of the site. Annually, the fifteen air monitoring stations maintained around the Nine Mile Point Site provide 795 individual air particulate samples which are assembled by location into 60 quarterly composite samples. The quarterly composites are analyzed using gamma spectroscopy.

No plant-related gamma emitting radionuclides were detected in any of the air particulate filter samples collected during 2016.

The gamma analysis results for the quarterly composite samples routinely showed positive detections of Be-7 and K-40. Both of these radionuclides are naturally occurring.

5 - 17

B. Data Evaluation Discussion A total of fifteen air sampling stations are m continuous operation and located both onsite and in the offsite sectors surrounding the Nine Mile Point Site. Each of the weekly air particulate filters collected for the quarter is assembled by location to form quarterly composite samples. The quarterly composite samples required by the ODCM are composite samples assembled for RI , R2, R3 , R4 and RS. Other sample locations not required by the ODCM, for which analytical results have been provided, include six onsite locations and four offsite locations. The analytical results for the 60 air particulate filter composites in 2016 showed no detectable activity of plant related radionuclides.

The results of the quarterly composite samples are presented in Section 6.0, Table 6-9.

C. Dose Evaluation The calculated dose as a result of plant effluents is not evaluated due to the fact that no plant related radionuclides were detected in 2016. The monthly air particulate sampling program demonstrated no offsite dose to man from this pathway as a result of operations of the plants located at the Nine Mile Point Site (NMP).

D. Data Trends No plant related radionuclides were detected during 2016 at the offsite air monitoring locations.

The ten year database of air particulate composite analysis shows that there is no buildup or routine presence of plant related radionuclides in particulate form in the atmosphere around the site. Historically Co-60 was detected in each of the years from 1977 through 1984 at both the indicator and control locations, with the exception of 1980 when Co-60 was not detected at the control location. The presence of Co-60 in the air samples collected during these years was the result of atmospheric weapons testing. Co-60 was again detected in an offsite 2000 indicator sample and was the only positive detection of Co-60 since 1984. The detection of Co-60 in the one 2000 sample was an isolated event associated with effluents from the NMPl facility. There have been no subsequent measurable concentrations of Co-60 in the environment surrounding the NMP site.

Historical data shows that Cs-13 7 is the fission product radionuclide most frequently detected in the air particulate filter composites. Cs-13 7 was detected in each of the years from 1977 through 1983 at both the control and indicator sampling locations. The presence of Cs-13 7 in the air samples collected during these years was the result of atmospheric weapons testing. Cs-13 7 was again detected in 1986 as a result of the Chernobyl accident. Since 1986 there have been no detections of Cs-13 7 in the environment surrounding the NMP site.

Historical data for air particulate results are presented in Section 7.0, Tables 7-11 and 5 - 18

5.2.3 AIRBORNE RADIOIODINE (1-131)

A. Results Summary Iodine-131 was not detected in any of the 795 samples analyzed for the 2016 program.

B. Data Evaluation and Discussion Airborne radioiodine (I-131) is monitored at the fifteen air sampling stations also used to collect air particulate samples. There are five offsite locations, required by the ODCM. Ten air sampling locations are also maintained in addition to those required by the ODCM. Six of these stations Dl , G, H, I, J and Kare located onsite. D2, E, F and Gare the optional stations located offsite. Samples are collected using activated charcoal cartridges. They are analyzed weekly for I-131.

The analytical data for radioiodine are presented in Section 6.0, Tables 6-7 and 6-8.

C. Dose Evaluation The calculated dose as a result of I-131 in plant effluents is not evaluated due to the fact that no I-131 was detected in 2016. The I-131 sampling program demonstrated no offsite dose to man from this pathway as a result of operation of the plants located at Nine Mile Point.

D. Data Trends There was no 1-131 detected in any of the samples, collected from the 15 sample stations, for 2012 through 2016.

In 2011 , 1-131 was detected at all 15 sampling locations over a three week period. The positive detections were the result of the Fukushima event. Prior to then, there had been no positive detection ofl-131 in air samples collected from 2002 to 2010.

1-131 has previously been detected in samples collected in 1986 and 1987. The 1986 detection of I-131 was the result of the Chernobyl accident and the 1987 detection was the result of plant operations.

1-131 has been detected in the past at control locations. Control samples collected during 1976 had a mean 1-131 concentration of 0.60 pCi!m 3 . During 1977 this mean decreased to 0.32 pCi!m3, and further decreased by a factor of ten to 0.03 pCi!m 3 in 1978. 1-131 was not detected in samples collected from the control location during 1979 - 1981 and 1983 to 1985.

1-131 was detected once at the control location during 1982 at a concentration of 0.039 pCi!m3 Historical data for 1-131 are presented in Section 7 .0, Tables 7-13 and 7-14.

5.2.4 DIRECT RADIATION THERMOLUMINESCENT DOSIMETERS (TLD)

A. Results Summary Thermoluminescent dosimeters (TLDs) are used to measure direct radiation (gamma dose) in the environment. As part of the 2016 environmental monitoring program, TLDs were placed at a total of 72 different environmental TLD locations (32 required by the ODCM and 40 optional locations). These TLDs were placed, collected and read each quarter of 2016. As a result of placing two TLDs at each location, the results presented in this report are the average of two TLD readings obtained for a given location.

The TLDs were placed in the following five geographical locations around the site boundary:

Onsite (areas within the site boundary, includes TLD #s 3, 4, 5, 6, 7, 23 , 24, 25 , 26; TLD

s 18, 27, 28, 29, 30, 31 , 39, 47, 103, 106, 107 are excluded)

Site Boundary (area of the site boundary in each of the 16 meteorological sectors: Only includes TLD results that are not affected by radwaste building direct shine, includes TLD

s 7, 18, 78, 79, 80, 81 , 82, 83 , 84; TLD #s: 23 , 75 , 76, 77, 85 , 86, 87 are excluded)

Offsite Sector (area four to five miles from the site in each of the eight land based meteorological sectors, includes TLD #s: 88, 89, 90, 91 , 92, 93 , 94, 95)

Special Interest (areas of high population density, includes TLD #s 15, 56, 58, 96, 97, 98)

Control (areas beyond significant influence of the site, includes TLD #s 14, 49)

All geographical locations are required by the ODCM with the exception of the Onsite area which was optional. Description of the five geographical categories and the designation of specific TLD locations that make up each category is presented in Section 3.1.5, TLD (Direct Radiation) of this report.

A summary of the 2016 dose rates for each of the five geographical locations is as follows:

Dose in rnrem per standard month Geographic Category Min Max Mean Onsite (Optional) 3.5 11.3 4.8 Site Boundary (Inner Ring)

3.5 4.8 4.0 Offsite Sectors (Outer Ring)

3.3 4.6 3.9 Special Interest

3.5 4.4 3.9 Control* 3.6 4.3 3.9

Geographical locations required by the ODCM Comparison of annual mean dose rates associated with each geographical location indicate that there is no statistical difference in annual dose as a function of distance from the site boundary.

The measured annual dose rate at the nearest resident to the site was consistent with the dose rates measured at the site boundary and control locations. The results for the Site Boundary, Offsite Sectors and Special Interest (Offsite) were well within expected normal variation when compared to the Control TLD results.

5 - 20

The results for the 2016 environmental TLD monitoring program indicate that there was no significant increase in dose rates as a result of operations at the site. The Hydrogen Water Chemistry system and the Independent Spent Fuel Storage Installation (ISFSI) in use at the JAFNPP and NMPNS did not measurably increase the ambient radiation exposure rate beyond the site boundary.

B. Data Evaluation and Discussion Direct Radiation (Gamma Dose) measurements were taken at 72 different environmental locations during 2016, 32 of which are required by the ODCM. These locations are grouped into five geographical location categories for evaluation of results. The five categories include: Onsite, Site Boundary, Offsite Sector, Special Interest and Control locations. All categories are required by the ODCM with the exception of the Onsite TLDs. Onsite TLDs are placed at various locations within the site boundary to provide additional information on direct radiation levels at and around the NMPl , NMP2 and JAFNPP facilities.

Onsite TLD results ranged from 3.5 to 11.3 mrem per standard month resulting in an average dose rate of 4.8 mrem per standard month in 2016.

The highest dose rate measured at a location required by the ODCM was 8.2 mrem per standard month. This TLD, (TLD 87) represents the site boundary maximum dose and is located in the NNW sector along the lakeshore in close proximity to the Nine Mile Point 1 plant. The TLD locations along the lakeshore close to the plants (TLD #s: 23, 75, 76, 77, 85, 86 and 87) are influenced by radwaste buildings and radwaste shipping activities. These locations are not accessible to members of the public and the TLD results for these areas are not representative of dose rates measured at the remaining site boundary locations.

Offsite Sector TLDs, required by the ODCM, located 4 to 5 miles from the site in each of the 8 land based meteorological sectors ranged from 3.3 to 4.6 mrem per standard month with an average dose rate of 3.9 rnrem per standard month.

Special Interest TLDs from all locations ranged from 3.5 to 4.4 rnrem per standard month with an average dose rate of 3.9 rnrem per standard month.

The Control TLD group required by the ODCM utilizes locations positioned well beyond the site.

2016 Control TLD results ranged from 3.6 to 4.3 rnrem per standard month with an annual average dose rate of3.9 rnrem per standard month.

TLD analysis results are presented in Section 6.0, Table 6-10.

C. Dose Evaluation 2016 annual mean dose rates for each geographic location required by the ODCM (excluding TLD #s: 23, 75, 76, 77, 85, 86, 87) are as follows:

5 - 21

Site Boundary: 4.0 mrem per standard month (TLD #s: 7,18, 78, 79, 80, 81 , 82, 83, 84)

Offsite Sectors: 3.9 mrem per standard month (TLD #s: 88, 89, 90, 91 , 92, 93, 94, 95)

Special Interest: 3.9 mrem per standard month (TLD #s: 15, 56, 58, 96, 97, 98)

Control: 3 . 9 mrem per standard month (TLD #s: 14, 49)

The measured mean dose rate in the proximity of the closest resident was 4.0 mrem per standard month (TLD #s: 108, 109) which is consistent with the control measurements of 3.9 rnrem per standard month.

The mean annual dose for each of the geographic location categories demonstrates that there is no statistical difference in the annual dose as a function of distance from the site. The TLD program verifies that operations at the site do not measurably contribute to the levels of direct radiation present in the offsite environment.

D. Data Trends A comparison of historical TLD results can be made using the different geographical categories of measurement locations. These include Site Boundary TLDs located in each of the 16 meteorological sectors, TLDs located offsite in each land based sector at a distance of 4 to 5 miles from the site, TLDs located at special interest areas and TLDs located at control locations. Site Boundary, Offsite Sector and Special Interest TLD locations became effective in 1985; therefore, trends for these results can only be evaluated from 1985 to the present.

The following graph illustrates TLD results for the Control, Site Boundary, Offsite Sectors and Special Interest groups from 2000 through 2016:

The 2016 TLD program results, when compared to the previous ten years, showed no significant trends relative to increased dose rates in the environment.

Historical data for the various TLD groupings are presented in Section 7.0, Tables 7-15 through 7-20.

5.2.5 MILK A. Results Summary A total of 36 milk samples were collected during the 2016 program and analyzed for gamma emitting radionuclides using gamma spectroscopy. In addition, each sample undergoes an iodine extraction procedure to determine the presence of Iodine-131 (1-131 ).

1- 131, a possible plant related radionuclide, is measured to evaluate the cow milk dose pathway to man. 1-131 was not detected in any of the 36 milk samples collected in 2016 from the two milk sample locations.

Gamma spectral analyses of the milk samples showed only naturally occurring radionuclides, such as K-40, were detected in milk samples collected during 2016. K-40 was detected in all indicator and control samples. K-40 is a naturally occurring radionuclide and is found in many environmental sample media.

The 2016 results demonstrate that routine operations of the Nine Mile Point Site resulted in no measurable contribution to the dose to the public from the cow/milk pathway.

B. Sampling Overview Milk samples were collected from one indicator location and one control location. The ODCM requires that three sample locations be within five miles of the site. Based on the milk animal census, there were no adequate milk sample locations within five miles of the site in 2016.

Samples were collected from two farms located beyond the five- mile requirement to ensure the continued monitoring of this important pathway. The indicator location was located 8.8 miles from the site. The control samples were collected from a farm located 16.0 miles from the site and in a low frequency wind sector (upwind). The geographic location of each sample location is listed below:

Location No. Direction From Site Distance (Miles) 55 E 8.8 77 (Control) s 16.0 Indicator location #55 and Control location #77 were sampled from April through December.

Sampling occurs during the first and second half of each month. Samples were not required to 5 - 23

be collected during January through March of 2016 due to I-131 not having been detected in samples collected during November and December of 2015, as stipulated in the ODCM.

C. Data Evaluation and Discussion Each milk sample is analyzed for gamma emitters using gamma spectral analysis. The I-131 analysis is performed using resin extraction followed by spectral analysis for each sample. I-131 and gamma analysis results for milk samples collected during 2016 are provided in Section 6.0, Table 6-11.

Iodine-131 was not detected in any indicator or control milk samples analyzed during 2016. All I-131 milk results were reported as Lower Limits of Detection (LLD). No plant-related radionuclides were detected in any milk sample collected in 2016. Cs-137 was not detected in any indicator or control milk sample collected in 2016. K-40 was the most abundant radionuclide detected, and found in every indicator and control sample collected. K-40 is a naturally-occurring radionuclide and is found in many of the environmental media samples.

D. Dose Evaluation The calculated dose as a result of plant effluents is not evaluated due to the fact that no plant related radionuclides were detected.

The dose to man from naturally occurring concentrations of K-40 in milk and other environmental media can be calculated. This calculation illustrates that the dose received due to exposure from plant effluents is negligible compared to the dose received from naturally occurring radionuclides. Significant levels of K-40 have been measured in environmental samples. A 70 kilogram (154 pound) adult contains approximately 0.1 microcuries of K-40 as a result of normal life functions (inhalation, consumption, etc.). The dose to bone tissue is about 20 mrem per year as a result of internal deposition of naturally-occurring KAO.

E. Data Trends Man-made radionuclides are not routinely detected in milk samples. In the past thirty.years, Cs-137 was only detected in 1986, 1987, and 1988. The mean Cs-137 indicator activities for those years were 8.6, 7.4 and 10.0 pCi/liter, respectively. I-131 was measured in two milk samples collected in 1997 from a single sample location, having a mean concentration of 0.35 pCi/liter and was of undetermined origin. The previous detection was in 1986 with a mean concentration of 13 .6 pCi/liter. The 1986 activity was a result of the Chernobyl accident.*

The comparison of 2016 data to historical results over the operating life of the plants shows that Cs-137 and I-131 levels in milk dropped to less than the lower limit of detection since 1988.

Historical data of milk sample results for Cs-13 7 and I-131 are presented in Section 7 .0, Tables 7-21 and 7-22.

5.2.6 FOOD PRODUCTS (VEGETATION)

A. Results Summary There were no plant-related radionuclides detected in the nine food product samples collected and analyzed for the 2016 program.

Detectable levels of naturally occurring K-40 were measured in all of the indicator and control samples collected for the 2016 program. Be-7 and Th-228 both naturally-occurring radionuclides, were also detected intermittently in samples collected in 2016. These results are consistent with the levels measured in 2015 and previous years.

The results of the 2016 sampling program demonstrate that there is no measurable impact on the dose to the public from the garden pathway as a result of plant operations.

B. Data Analysis and Discussion Food product samples were collected from two indicator locations and one control location. The indicator locations are represented by nearby gardens in areas of highest D/Q (deposition factor) values based on historical meteorology and an annual garden census. The control location was a garden 15.4 miles away in a predominately upwind direction.

Food product samples collected during 2016 included both edible and nonedible vegetation.

Nonedible samples include: grape leaves, horseradish leaves, rhubarb leaves, squash leaves and pumpkin leaves. The edible vegetation used in this year's sampling was cabbage. The leaves of these plants were sampled as representative of broadleaf vegetation which is a measurement of radionuclide deposition. Samples were collected during the late summer/fall harvest season.

Each sample was analyzed for gamma emitters using gamma spectroscopy.

The analysis of food product samples collected during 2016 did not detect any plant- related radionuclides. Results for the past five years also demonstrate that there is no buildup of plant-related radionuclides in the garden food products grown in areas close to the site.

Naturally-occurring Be-7, K-40 and Th-228 were detected in food product samples. The results for naturally-occurring radionuclides are consistent with*the data of prior years.

Analytical results for food products are found in Section 6.0, Table 6-12.

C. Dose Ev;:tluation The calculated dose as a result of plant effluents is not evaluated due to the fact that no plant-related radionuclides were detected. The food product sampling program demonstrated no measurable offsite dose to man from this pathway as a result of operations of the plants located at Nine Mile Point.

5 - 25

D. Data Trends Food product/vegetation sample results for the last five years demonstrate that there is no chronic deposition or buildup of plant-related radionuclides in the garden food products in the environs near the site.

The last positive indication was for Cs-137 which was detected at one indicator location in 1999 with a concentration of0.007 pCi/g (wet).

Historically, Cs-137 had been detected in ten separate years since 1976 ranging from a maximum mean concentration of 0.047 pCi/g (wet) in 1985 to a minimum of 0.004 pCi/g (wet) in 1980.

The trend for Cs-137 is a general reduction in concentration to non detectable levels in samples collected during the 2000 through 2016 sample programs.

Historical data of food product results are presented in Section 7.0, Tables 7-23 and 7-24.

5.2. 7 LAND USE CENSUS RESULTS A. Results Summary The ODCM requires that an annual land use census be performed to identify potential new locations for milk sampling and for calculating the dose to man from plant effluents. In 2016 a milk animal census, a nearest resident census, and a garden survey were performed.

B. Data Evaluation and Discussion A land use census is conducted each year to determine the utilization of land in the vicinity of the Nine Mile Point site. The land use census consists of two types of surveys.* A milk animal census is conducted to identify all milk animals within a distance of 10 miles from the site. This census, covering areas out to a distance of 10 miles exceeds the 5 mile distance required by the ODCM.

A total of 225 milk cows and 167 heifers were observed. Additionally approximately 30 goats were counted at one location during the survey. Attempts to contact the land owner were made by phone, post card and visitation but no response was received. The milking/non-milking status of these approximately 30 goats is currently unknown. There are no farms with milking animals with the 5 mile radius of the site.

The second type of census conducted is a residence census. The census is conducted in order to identify the closest residence within 5 miles in each *of the 22.5 degree land- based meteorological sectors. There are only eight sectors over land where residences are located within 5 miles. The survey for 2016 found new construction located in the South Sector at 294 Miner Road, Lycoming, New York. The location was determined to be 1.59 miles away from the center of the NMP2 Reactor Building at the 162 degrees. The new location is closer than the previously used 268 Miner Road address, which was 1.67 miles away at the 171 degree line.

5 - 26 L_

The results of the residence census, showing the applicable sectors and direction and distance of each of the nearest residern;:e, are found in Section 6.0, Table 6-14. There was 1 change identified in the 2016 census. A new residence was found in the SSE meteorological sector and it has been added to the residence census table. The nearest resident locations are illustrated in Section 3.3, Figure 3.3-5.

The results of the nearest residence census conducted m 2016 required no change to ODCM's closest resident location.

A garden survey, not required by the ODCM, is performed to identify appropriate garden sampling locations and dose calculation receptors. The 2016 garden survey identified a total of 63 gardens for consideration for the sampling program. Garden samples were collected from two locations (144 and 484) as well as a control lOcation (C2) identified in census as active for 2016. See Table 3.3-1for2016 sampling locations.

5.2.8 DIRECT RADIATION, THERMOLUMINESCENT DOSIMETERS (TLD)

Independent Spent Fuel Storage Installation (ISFSI)

A. Results Summary TLDs are used to measure direct radiation (gamma dose) at the site boundary and Optically Stimulated Luminescence Dosimeters (OSLDs) are used to measure direct radiation (gamma dose) in the localized environment of the ISFSI pad. Sixteen TLDs are located around the site, one in each of the sixteen compass sectors, and fourteen OSLDs are located around the perimeter of the ISFSI pad and specific areas of interest. OSLDs were placed at these locations prior to- loading the first storage casks for baseline dose rate determination in the general area of the pad.

During 2016, there were no casks moved to the storage facility. The total number of casks in storage is twenty four.

The implementation and loading of the ISFSI project has resulted in no increase in dose at the site boundary or to the public. The analysis of offsite doses from direct radiation measurements, presented in Section 5.2.4 of this report, concludes that there is no significant difference in annual dose to the public at or beyond the*site boundary. The measured annual dose rate at the nearest residence to the site was consistent with the dose rates measured at the site boundary and the offsite control locations. The results for the Site Boundary, Offsite Sectors, and Special Interest (offsite) were well within expected normal variation when compared to the Control TLD results. The results for the 2016 environmental TLD monitoring program indicate that there is no significant increase in dose rates as a result of operations at the site. The implementation of the ISFSI at the NMPNS plant did not measurably increase the ambient radiation exposure rate 5-27

at or beyond the site boundary. The lack of a dose rate increase at or beyond the site boundary is consistent with design calculations performed to evaluate compliance with 10 CFR 72.104(a).

The measured results of the 2016 TLD monitoring program demonstrate compliance with the offsite dose limits to members of the public specified in 40CFR190 and 10 CFR 72.104(a).

B. Program Design An array of ten OSLD locations was established around the perimeter of the ISFSI pad and four OSLD locations were placed in specific areas of interest twelve months prior to facility usage.

These pre-operational OSLDs were used for baseline dose rate determination. The OSLDs are placed, collected and read *each quarter. Two dosimeters are placed at each location and the average of the two dosimeters is reported. The quarterly results are compared to baseline data to assess the contribution to ambient dose rates in the vicinity of the storage facility from casks as they are placed on the storage pad.

C. Dose Evaluation The pre-operation minimum and maximum dose rates were 2.9 and 6.3 mrem per standard month, respectively. During 2016, the maximum dose rate of 9 .3 mrem per standard month was measured at OSLD location 241, north of the ISFSI.

The following table presents the pre-operation dose rate data and the operational dose rate data for 2016:

Pre-Operation 2016 OSLD Sector mrem per Standard mrem per Standard Number month Month 233 WNW 3.5 5.4 234 WSW 2.9 3.6 235 s 4.2 3.5 236 SSE 3.8 3.5 237 SE 3.0 3.7 238 ESE 3.5 3.9 239 E 4.0 6.3 240 NE 3.6 6.4 241 N 5.1 8.3 242 NE 6.3 5.3 243 NNW 4.8 5.8 244 NE 4.6 4.1 245 NE 4.0 6.2 246 ENE 4.8 4.5 5 - 28

An evaluation of Site Boundary TLDs and Control TLDs results for 2016 shows that there is no increase in dose rate at or beyond the site boundary. A detailed discussion of this evaluation is found in Section 5.2.4. The Environmental TLD results for this period show no significant difference in control and site boundary dose rates compared to 2015 and preoperational data gathered in 2012.

5.3 CONCLUSION

The Radiological Environmental Monitoring Program (REMP) is an ongoing program implemented to measure and document the radiological impact of NMPNS operations on the local environment. The program is designed to detect and evaluate small changes in the radiological environment surrounding the site. Environmental media representing food sources consumed at the higher levels of the food chain, such as fish, food products and milk, are part of a comprehensive sampling program. Results of all samples are reviewed closely to determine any possible impact to the environment or to man. In addition, program results are evaluated for possible short-term and long-term historical trends.

The federal government has established dose limits to protect the public from radiation and radioactivity. The Nuclear Regulatory Commission (NRC) specifies a whole body dose limit of 100 mrem/yr to be received by the maximum exposed member of the general public. This limit is set forth in Section 1301, Part 20, Title 10 of the U.S. Code of Federal Regulations (10 CFR 20). The Environmental Protection Agency (EPA) limits the annual whole body dose to 25 mrem/yr, which is specified in Section 10, Part 190, Title 40, of the Code of Federal Regulations (40 CFR 190). Radiation exposure to members of the public, calculated based on the results of the REMP, is. extremely small. The dose to members of the public from operations at the Nine Mile Point site, based on environmental measurement and calculations made from effluent releases, is determined to be a fraction of limits set forth by the NRC and EPA.

The REMP continues to demonstrate that the effluents from the site to the environment contribute no significant or even measurable radiation exposures to the general public as confirmed by the sampling and analysis of environmental media from recognized environmental pathways. Based on TLD results there was no measurable increase in radiation levels beyond the site boundary as a result of the hydrogen water chemistry and ISFSI programs. Environmental radiation levels measured at the nearest residence are at the background level based on control station TLD results.

The only measurable radiological impact on the environment continues to be the result of atmospheric weapons testing conducted in the early 1980's, the 1986 accident at the Chernobyl Nuclear Power Plant, and the March 11, 2011 accident at the Fukushima Daiichi Nuclear Power Station.

The REMP did not detect any plant-related radionuclide in the sample media collected during 2016. Dose from man-made sources in the environment is very small when compared to the dose originating from naturally-occurring sources of radioactivity.

Radiation from naturally-occurring radionuclides such as K-40 and Ra-226 contributed the vast majority of the total annual dose to members of the general public. The dose to members of the public, resulting from plant operations, is extremely small in comparison to the dose contribution from natural background levels and sources other than the plants. The whole body dose in Oswego County due to natural sources is approximately 4 7 mrem per individual per year as demonstrated by control environmental TLDs. The fraction of the annual dose to man, attributable to site operation, remains insignificant.

Based upon the overall results of the 2016 Radiological Environmental Monitoring Program, it can be concluded that the levels and variation of radioactivity in the environment samples were consistent with background levels. Effluents from the site to the environment contribute no significant or even measurable radiation exposures to the general public.

6.0 REPORT PERIOD ANALYTICAL RESULTS TABLES Environmental sample data is summarized in table format. Tables are provided for select sample media and contain data based on actual values obtained over the year. These values are comprised of both positive values and LLD (Lower Limit of Detection) values where applicable.

The LLD is the smallest concentration of radioactive material in a sample that will be detected with 95% probability and with 5% probability of falsely concluding that a blank observation represents a "real" signal (see Section 3.7.3 for detailed explanation).

When the initial count of a sample indicates the presence of radioactivity, two recounts are normally performed. When a radionuclide is positively identified in two or more counts, the analytical results for that radionuclide are reportec;l as the mean of the positive detections and the associated error for that mean (see Section 3.7.2 for methodology).

Many of the tables are footnoted with the term "Plant Related Radionuclides". Plant Related Radionuclides are radionuclides that are produced in the reactor as a result of plant operation, either through the activation or fission process.

8.0 QUALITY ASSURANCE I QUALITY CONTROL PROGRAM 8.1 PROGRAM DESCRIPTION The Offsite Dose Calculation Manual (ODCM), Part 1, Section 5.3 requires that the licensee participate in an Interlaboratory Comparison Program. The Interlaboratory Comparison Program shall include sample media for which samples are routinely collected and for which comparison samples are commercially available. Participation in an Interlaboratory Comparison Program ensures that independent checks on the precision and accuracy of the measurement of radioactive material in the environmental samples are performed as part of the Quality Assurance Program for environmental monitoring. To fulfill the requirement for an Interlaboratory Comparison Program, the Teledyne Brown Engineering (TBE) Environmental Services laboratory has engaged the services of Eckert &
Ziegler Analytics, Incorporated in Atlanta, Georgia, The Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) located in Idaho Falls, Idaho, and Environmental Resource Associates (ERA) in Golden, Co.
The Interlaboratory Comparison providers supply sample media as blind sample spikes, which contain certified levels of radioactivity unknown to the analysis laboratory. These samples are prepared and analyzed by the Teledyne Brown Engineering Environmental Services laboratory using standard laboratory procedures.

8.3.1 SAMPLE RESULTS EVALUATION.
Analytics:
Analytics evaluation report provides a ratio of TBE's result and Analytics' known value.
Since flag values are not assigned, TBE evaluates the reported ratios based on internal QC requirements, which are based on the DOE/MAPEP criteria. The ratio of 0.80 to 1.20 is evaluated as acceptable. The ratios of 0.70 to 0.79 and 1.21 to 1.30 are evaluated as acceptable with warning.
DOE Evaluation Criteria (Handbook for the Department of Energy's Mixed Analyte Performance Evaluation Program (MAPEP), Revision 13 (June 2012), pp 37-38, retrieved from http://www.id.energy.gov/resl/mapep/handbookv 13 .pdf)
MAPEP:
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.
False positive/negative testing and sensitivity evaluations are used in radiological performance evaluations. The specific analytes used for testing vary among performance evaluation test sessions.
The MAPEP program uses false positive testing to identify laboratory results that indicate the presence of a particular radionuclide in a MAPEP sample when, in fact, the actual activity of the radionuclide is far below* the detection limit of the measurement. Not acceptable ("N") performance, and hence a false positive result, is indicated when the range encompassing the result, plus or minus the total uncertainty at three standard deviations, does not include zero (e.g. 2.5 +/- 0.2; range of 1.9 - 3.1). Statistically, the probability that a result can exceed the absolute value of its total uncertainty at three standard deviations by chance alone is less than 1%. The MAPEP uses a three standard deviation criterion for the false positive test to ensure confidence about issuing a false positive performance. evaluation. A result that is greater than three times the total uncertainty of the measurement represents a statistically positive detection with over 99%
confidence.
Sensitivity evaluations are routinely performed to complement the false positive tests. In a sensitivity evaluation the radionuclide is present at or near the detection limit, and the difference between the report result and the MAPEP reference value is compared to the
propagated combined total uncertainties. The results are evaluated at three standard deviations. If the observed difference is greater than three time the combined total uncertainty, the sensitivity evaluation in "Not Acceptable". The probability that such a difference can occur by chance alone is less than 1%. If the participant did not report a statistically positive result, a "Not Detected" is noted in the text field of the MAPEP performance report. A non-detect is potentially a false negative result, dependent upon the laboratory's detection limit for the radionuclide.
False negative tests are also performed in combination with the sensitivity evaluations. In this scenario, the sensitivity of the reported measurement indicates that the known specific activity of the targeted radionuclide in the performance evaluation sample should have been detected, but was not, and a "Not Acceptable" performance evaluation is issued.
The uncertainty of the MAPEP reference value and of the reported result at three standard deviations is used for the false negative test.
The false positive/negative and sensitivity evaluation tests are conducted in a manner that assists the participants with their measurement uncertainty estimates and helps ensure they are not under estimating or over inflating their total uncertainties. If the total uncertainty is over inflated to try to pass a false positive test, it will result in a "Not Detected" if the test is actually a sensitivity evaluation, and vice versa for a false positive test. False negatives and failed sensitivity evaluations can also result from under estimating the total uncertainty. An accurate estimate of measurement uncertainty is required for consistent performance at the acceptable level.
ERA:
The ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. The ERA's acceptance limits are established per the. USEPA, NELAC, state specific performance testing 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.

SUMMARY
The Interlaboratory Comparison Program numerical results for the TBE Environmental Services laboratory are provided on Table 8-3.
8.4.1 ECKERT & ZIEGLER ANALYTICS, DOE MAPEP, and ERA QA SAMPLES RESULTS For the TBE laboratory, 156 out of 160 analyses performed met the specified acceptance criteria, for a 97.5 agreement ratio. 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.
1. Teledyne Brown Engineering's MAPEP February 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. 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 The MAPEP February 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 December 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 l .2L (Normally we use .6L for client samples). NCR 16-35

SUMMARY
Routine quality control (QC) testing was performed for dosimeters issued by the Environmental Dosimetry Company (EDC) .
During this annual period, 100% (72/72) of the individual dosimeters, evaluated against the EDC internal performance acceptance criteria (high-energy photons only), met the criterion for accuracy and 100% (72/72) met the criterion for precision (Table 1). In addition, 100% (12/12) of the dosimeter sets evaluated against the internal tolerance limits met EDC acceptance criteria (Table 2) and 100% (6/6) of independent testing passed the performance criteria (Table 3). Trending graphs, which evaluate performance statistic for high-energy photon irradiations and co-located stations are given in Appendix A.
One internal assessment was performed in 2016. There were no findings.

I. INTRODUCTION The TLD systems at the Environmental Dosimetry Company (EDC) are calibrated and operated to ensure consistent and accurate evaluation of TLDs. The quality of the dosimetric results reported to EDC clients is ensured by in-house performance testing and independent performance testing by EDC clients, and both internal and client directed program assessments.
The purpose of the dosimetry quality assurance program is to provide performance documentation of the routine processing of EDC dosimeters. Performance testing provides a statistical measure of the bias and precision of dosimetry processing against a reliable standard, which in turn points out any trends or performance changes. Two programs are used:
A. QC Program Dosimetry quality control tests are performed on EDC Panasonic 814 Environmental dosimeters. These tests include: (1) the in-house testing program coordinated by the EDC QA Officer and (2) independent test perform by EDC clients. In-house test are performed using six pairs of 814 dosimeters, a pair is reported as an individual result and six pairs are reported as the mean result.
Results of these tests are described in this report.
Excluded from this report are instrumentation checks. Although instrumentation checks represent an important aspect of the quality assurance program, they are not included as process checks in this report. Instrumentation checks represent between 5-10% of the TLDs processed.
S: QA Program An internal assessment of dosimetry activities is conducted annually by the Quality Assurance Officer (Reference 1). The purpose of the assessment is to review procedures, results, materials or cc;imponents to identify opportunities to improve or enhance processes and/or services.
II. PERFORMANCE EVALUATION CRITERIA A. Acceptance Criteria for Internal Evaluations
1. Bias For each dosimeter tested, the measure of bias is the percent deviation of the reported result relative to the delivered exposure. The percent deviation relative to the delivered exposure is calculated as follows:
( H'I -H.)
I 100 Hi where:
H~ = the corresponding reported exposure for the i1h dosimeter (i.e., the reported exposure)
Hi = the exposure delivered to the i1h irradiated dosimeter (i.e., the delivered exposure) 9-1
2. Mean Bias For each group of test dosimeters, the mean bias is the average percent deviation of the reported result relative to the delivered exposure. The mean percent deviation relative to the delivered exposure is calculated as follows:
where:
H; = the corresponding reported exposure for the i1h dosimeter (i.e., the reported exposure)
Hi = the exposure delivered to the i1h irradiated test dosimeter (i.e., the delivered exposure) n = the number of dosimeters in the test group
3. Precision For a group of test dosimeters irradiated to a given exposure, the measure of precision is the percent deviation of individual results relative to the mean reported exposure. At least two values are required for the determination of precision. The measure of precision for the i1h dosimeter is:
where:
H; = the reported exposure for the i1h dosimeter (i.e., the reported exposure)
R = the mean reported exposure; i.e., R= :LH;(~)
n = the number of dosimeters in the test group
4. EDC Internal Tolerance Limits All evaluation criteria are taken from the "EDC Quality System Manual,"
(Reference 2). These criteria are only applied to individual test dosimeters irradiated with high-energy photons (Cs-137) and are as follows for Panasonic Environmental dosimeters: +/- 15% for bias and +/-
12.8% for precision.
9-2
B. QC Investigation Criteria and Result Reporting EDC Quality System Manual (Reference 2) specifies when an investigation is required due to a QC analysis that has failed the EDC bias criteria. The criteria are as follows:
1. No investigation is necessary when an individual QC result falls outside the QC performance criteria for accuracy.
2. Investigations are initiated when the mean of a QC processing batch is outside the performance criterion for bias.
C. Reporting of Environmental Dosimetry Results to EDC Customers
1. All results are to be reported in a timely fashion.
2. If the QA Officer determines that an investigation is required for a process, the results shall be issued as normal. If the QC results, prompting the investigation, have a mean bias from the known of greater than +/-20%, the results shall be issued with a note indicating that they may be updated in the future, pending resolution of a QA issue.
3. Environmental dosimetry results do not require updating if the investigation has shown that the mean bias between the original results and the corrected results, based on applicable correction factors from the investigation, does not exceed +/-20%.

SUMMARY
FOR ISSUANCE PERIOD JANUARY-DECEMBER 2016 A. General Discussion Results of performance tests conducted are summarized and discussed in the following sections. Summaries of the performance tests for the reporting period are given in Tables 1 through 3 and Figures 1 through 4.
Table 1 provides a summary of individual dosimeter results evaluated against the EDC internal acceptance criteria for high-energy photons only. During this period, 100% (72/72) of the individual dosimeters, evaluated against these criteria met the tolerance limits for accuracy and 100% (72/72) met the criterion for precision.
A graphical interpretation is provided in Figures 1 and 2.
Table 2 provides the Bias + Standard deviation results for each group (N=6) of dosimeters evaluated against the internal tolerance criteria. Overall, 100%
(12/12) of the dosimeter sets evaluated against the internal tolerance performance criteria met these criteria. A graphical interpretation is provided in Figure 3.
Table 3 presents the independent blind spike results for dosimeters processed during this annual period. All results passed the performance acceptance criterion. Figure 4 is a graphical interpretation of Seabrook Station blind co-located station results.

B. Result Trending One of the main benefits of performing quality control tests on a routine basis is to identify trends or performance changes. The results of the Panasonic environmental dosimeter performance tests are presented in Appendix A The results are evaluated against each of the performance criteria listed in Section II, namely: individual dosimeter accuracy, individual dosimeter precision, and mean bias.
All of the results presented in Appendix A are plotted sequentially by processing date.
IV. STATUS OF EDC CONDITION REPORTS (CR)
No condition reports were issued during this annual period.
V. STATUS OF AUDITS/ASSESSMENTS A Internal EDC Internal Quality Assurance Assessment was conducted during the fourth quarter 2016. There were no findings identified.
B. . External None.
VI. PROCEDURES AND MANUALS REVISED DURING JANUARY - DECEMBER 2016 Several procedures were reissued with no changes as part of the 5 year review cycle.
VII. CONCLUSION AND RECOMMENDATIONS The quality control evaluations continue to indicate the dosimetry processing programs at the EDC satisfy the criteria specified in the Quality System Manual. The EDC demonstrated the ability to meet all applicable acceptance criteria.
