SUMMARY

The Annual Radiological Environmental Operating Report is published pursuant to Section 6.6.2 of the Nine Mile Point Unit 1 (NMP1) Technical Specifications and Section 5.6.2 of the Nine Mile Point Unit 2 (NMP2) Technical Specifications.

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 Manuals (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 Interlaboratory Comparison Quality Assurance Program (ICQAP) required by the NMP 1 and NMP2 ODCM.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 and 40 CFR 190. 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 2011, there were 2,430 analyses performed on environmental media collected as part of the REMP.The results demonstrate that there was no significant or measurable radiological impact from the operation of either the NMUP1 or NMP2 facilities.

The 2011 results for all pathways sampled were consistent with the previous five-year historical results and exhibited no adverse trends.On March 11, 2011 at 1446, a magnitude

9.0 earthquake

struck off the east coast of Japan. The Fukushima Daiichi Nuclear Power Station, operated by Tokyo Electric Power Co., withstood the earthquake but lost all offsite electrical power sources to the site. Forty-one minutes later however, the plant was hit with a series of tsunamis and all AC power was lost and the facility went into a state of emergency.

The Nuclear Safety Commission of Japan estimated approximately 17 million curies of iodine-131 (1-131) equivalent radioactive material was released into the air and 0.127 million curies into the sea between March 11 and April 5. 1-131 was detected at the Nine Mile Point Nuclear Station site from the Fukushima Daiichi Nuclear Power Station event in both the indicator and control air sampling locations from March 22 through April 12, 2011.In summary, the analytical results from the 2011 REMP demonstrate that the routine operation of both facilities at the Nine Mile Point site had no significant or measurable radiological impact on the environment.

The results of the REMP continue to demonstrate that the operation of the plants did not result in a significant measurable dose to a member of the general population, or adversely impact the environment as a result of radiological effluents.

The program 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 and 40 CFR 190.1-1

2.0 INTRODUCTION

Nine Mile Point Units 1 and 2 are operated by Nine Mile Point Nuclear Station, 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 2011.Nine Mile Point Unit 1 (NMP1) and Nine Mile Point Unit 2 (NMP2) Radiological Environmental Monitoring Program (REMP) requirements reside within the NMP1 Offsite Dose Calculation Manual (ODCM) and NMP2 ODCM, respectively.

Throughout this report, references will be made to the ODCM.This refers to both the NMPI ODCM and the NMP2 ODCM.2.1 PROGRAM HISTORY Environmental monitoring of the Nine Mile Point (NMP) site has been on-going 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 data obtained during reactor operation.

In 1969, NMP1, a 1,850 Megawatt-Thermal (MWt) Boiling Water Reactor (BWR) began full power operation.

In 1975, the James A. FitzPatrick Nuclear Power Plant (JAFNPP), a 2,536 MWt BWR, currently owned and operated by Entergy, began full power operation.

In 1988, NMP2, a 3,323 MWt BWR located between NMP1 and JAFNPP, began full power operation.

In 1995, NMP2 was uprated to 3,467 MWt.In 1985, the individual station's Plant Effluent Technical Specifications were standardized to the generic Radiological Effluent Technical Specifications, much of which is common to both NMP1 and JAFNPP, and subsequently to NMP2. Subsequent Technical Specification amendments relocated the REMP requirements to the ODCM for all three plants. Data generated by the REMP is shared between Nine Mile Point Nuclear Station (NMPNS) and JAFNPP, but each operating company reviews and publishes their own annual report.In summary, the three BWRs, which together generate approximately 7,853 MWt, have operated collectively since 1988. A large database of environmental results for the exposure pathways has been collected and analyzed to determine the effect 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 of the 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 and the Offsite Dose Calculation Manuals.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: o Air o Fish* Food Products o Milk* Shoreline Sediment" Surface Waters" Groundwater 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 sample analysis 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 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 TABLE 3.0-1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM REQUIRED SAMPLE COLLECTION AND ANALYSIS Nine Mile Point Unit 1 Exposure Pathway and/or Sample Number of Samples (a) and Locations Sampling and Collection Frequency (a)Type of Analysis and Frequency AIRBORNE a.

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 shown in Section 3.3, Figure 3.3-5.3.1.2 FISH Samples of available fish species that are commercially or recreationally important to Lake Ontario, such as lake trout, salmon, walleye, and smallmouth bass, are collected twice per year, once in the spring and again in the fall. Indicator samples are collected from a combination of the two on-site sample transects located offshore from the site. One set of control samples are collected at an off-site sample transect located offshore, 8 -10 miles west of the site. Available species are selected using the following guidelines:

a. 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.

b. Samples are composed of the edible portion only.Selected fish samples are frozen 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 gamm-emitting radionuclides.

Fish collection locations are shown in Section 3.3, Figure 3.3-5.3.1.3 SURFACE WATER Surface water samples are taken from the respective inlet canals of the JAFNPP and the NRG Oswego Generating 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 Generating 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 Generating Station are also obtained using automatic sampling 3- 13 I 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.

i A portion of the monthly sample from each of the locations is saved and composited to form quarterly composite samples, that are analyzed for tritium. i In addition to the sample results for the JAFNPP and Oswego Generating Station collection sites, data is presented for the Nine Mile Point Unit 1 (NMP1) and Nine Mile Point Unit 2 (NMP2) facility inlet canal samples and from the City of Oswego drinking water supply. These 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.Sampling for groundwater and drinking water, as found in Section D 3.5.1 of the NMP2 ODCM, was not required during 2011. There was no groundwater source in 2011 that was tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties support contamination migration; I therefore, drinking water was not a dose pathway during 2011.Surface water sample locations are shown in Section 3.3, Figure 3.3-4. i 3.1.4 GROUNDWATER 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) 7 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 I 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.

During the operating year 2011, there were no unplanned releases or spills of radioactive liquids on the NMPNS site.Groundwater samples are analyzed using liquid scintillation detection and gamma isotopic analysis.Groundwater tritium results are documented in the 2011 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 3.3-6.3-14 3.1.5 AIR PARTICULATE

/ 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 annual site average ground-level deposition factor (D/Q) based on historical meteorological data.These stations (R-1, R-2, and R-3) are located in the E, ESE, and SE sectors as measured from the center of the NMP2 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 R-4. A fifth station required by the ODCM is a control location designated as Station R-5. Station R-5 is located 16.4 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 D 1, 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 SW sector in the vicinity of the City of Oswego and is designated as Offsite Station G. Three remaining air sampling stations are located in the ESE, SSE, and SSW sectors and range in distance from 7.2 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 sample cartridges (2 x 1 inches). 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 (Environmental Stations) are shown in Section 3.3, Figures 3.3-2 and 3.3-3.3.1.6 THERMOLUMMINESCENT DOSIMETERS (DIRECT RADIATION)

Thermoluminescent dosimeters (TLDs) are used to measure direct radiation (gamma dose) in the environment.

Environmental TLDs are supplied and processed quarterly by the AREVA NP Environmental Laboratory.

The laboratory utilizes a Panasonic based system using UD-814 dosimeters that are constructed of rectangular .teflon wafers impregnated with 25% CaSO 4:Dy phosphor.

Each dosimeter contains three calcium sulfate elements and one lithium borate element.Environmental TLDs are placed in five different geographical regions around the 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: 3- 15 TLD Geographical Category Description Category Description Onsite Site Boundary Offsite TLDs placed at various locations within the Site Boundary are not required by the ODCM, with the exception of TLD # 7, 18 and 23. (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)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*)An outer ring of TLDs placed -4 to 5 miles from the site in each of the eight 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*)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 groupare:

9, 10, 11, 12, 13, .15*, 19, 51, 52, 53, 54, 55, 56*, 58*, 96*, 97*, 98*, 99, 100, 101, 102, 108, and 109)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 12.6 to 24.7 miles. This category is also required by the ODCM. (TLD locations comprising this group are 8, 1'4*, 49*, 111, 113)Special Interest I I I I I I I I I I I I I I I I Control* TLD location required by ODCM 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 data.Two dosimeters are placed at each TLD monitoring location.

The TLDs are sealed in polyethylene packages to ensure dosimeter integrity, placed in open webbed plastic holders, and attached to supporting structures, such as utility poles.Environmental TLD locations are shown in Section 3.3, Figures 3.3-2 and 3.3-3.3- 16 3.1.7 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 during 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 next sampling year. Milk samples were not collected in January through March of 2011, as there were no positive detections of plant related radionuclides in Samples collected during November and December 2010.The ODCM also requires that a sample be collected from a control location nine to twenty miles from the site and in a least 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 butterfat.

Two gallons are collected from each indicator and control location during the first half and second half of each month. 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 shown in Section 3.3, Figure 3.3-4.3.1.8 FOOD PRODUCTS (VEGETATION)

Food products are collected once per year during the late summer harvest season. A minimum of three different kinds of broadleaf vegetation, edible or inedible, is collected from two different indicator garden locations.

Sample locations are selected from gardens identified in the annual census that have the highest calculated annual site average D/Q values based on historical site meteorological data. Control samples are also collected from available locations greater than 9.3 miles distant from the site in a least 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 and for carbon-14 (C-14) using liquid scintillation detection.

Food product locations are shown in Section 3.3, Figure 3.3-5.3.2 ANALYSES PERFORMED The following environmental sample analyses are performed by the JAFNPP Environmental Laboratory:

, FGMX-MW1 3 -28 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: This census is performed once per year in the summer 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 answered, 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. Several of the site meteorological sectors are located 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 is performed.

The census is conducted each year to identify the gardens near the site that are to be used for the collection of food product samples. The results of the garden census are not provided in this report. The results are used only to identify appropriate sample locations.

The garden census is not required by the ODCMs if broadleaf vegetation sampling and analysis is performed.

These methodologies include determination of standard deviation, the 3 mean and associated error for the mean and the lower limit of detection (LLD).I 3 -301

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 NMPNS REMP. The following equations were utilized to compute the mean (X) and the standard deviation (s): A. Mean n Xi N Where, X = estimate of the mean i = individual sample, i N, n = total number of samples, with positive indications Xi = value for sample i above the lower limit of detection B. Standard Deviation S-.1/2 n (N-i)-Where, X = mean for the values of X s = standard deviation for the sample population, 3.7.2 ESTIMATION OF THE MEAN AND THE ESTIMATED ERROR FOR THE MEAN In accordance with program policy, two recounts of samples are performed when the initial count indicates the presence of a plant-related radionuclide(s).

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 is available, the mean of the sample results and the estimated error for the mean are reported in the Annual Report.3 -31 The following equations were utilized to estimate the mean (X) and the associated propagated error.A. Mean-I I xi i=1 I N Where, 3 X = estimate of the mean i = individual sample, i N, n = total number of samples with positive indications 3 Xi = value for sample i above the lower limit of detection I B. Error of the Mean n ( 1/2 ERROR MEAN = (ERROR)2 N Where, ERROR MEAN = propagated error i = individual sample ERROR = 1 sigma* error of the individual analysis N, n = number of samples with positive indications

• Sigma (a)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.3.7.3 LOWER LIMIT OF DETECTION (LLD)The LLD is the predetermined concentration or activity level used to establish a detection limit for the I 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: 3-32 4.66 Sb LLD =(E) (V) (2.22) (Y) exp (-XAt)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 At = the elapsed time between sample collection (or end of the sample collection period) and time of counting The ODCM LLD formula assumes that:* The counting times for the sample and background are equal" 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 3.7-1 lists the ODCM program required LLDs for specific media and radionuclides.

The LLDs actually achieved are routinely lower than those specified by the ODCM.3-33 TABLE 3.7-1 REQUIRED DETECTION CAPABILITIES FOR ENVIRONMENTAL SAMPLE ANALYSIS LOWER LIMIT OF DETECTION (LLD)Analysis Water (pCi/1)Airborne Particulate or Gases (pCi/m 3)Fish (pCi/kg, wet)Milk (pCi/1)Food Products (pCi/kg, wet)Sediment (pCi/kg, dry)Gross Beta H-3 Mn-54 Fe-59 4 0.01 3000 (a)Co-58, Co-60 Zn-65 Zr-95, Nb-95 1-131 Cs- 134 Cs-137 Ba/La- 140 15 30 15 30 15 130 260 130 260 15 (a)15 18 15 0.07 0.05 0.06 1 130 150 15 18 15 60 60 80 150 180 (a) No drinking water pathway exists at the Nine Mile Point Site under normal operating conditions due to the direction and distance of the nearest drinking water intake.

3.8 COMPLIANCE

WITH REQUIRED LOWER LIMITS OF DETECTION (LLD)Tables D 4.6.20-1 and D 3.5.1-3 of the NMPI ODCM and NMP2 ODCM, respectively, specify the detection capabilities for environmental sample analysis (See Table 3.7-1). The reporting requirements of NMIP1 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.

All sample analyses performed in 2011, 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 DOSE LIMITS Two federal agencies, the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA) have responsibility for regulations promulgated for protecting the public from radiation and radioactivity beyond the site boundary.3.9.1 The Nuclear Regulatory Commission The NRC, in 10 CFR 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 10 CFR 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 radionuclides with half-lives greater than eight days in gaseous effluents is limited to:* less than or equal to 15 mrem per year to any organ.3 -35 I I 3.9.2 Environmental Protection Agency The EPA, in 40 CFR 190.10 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 whole 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.I I I I I I I I I I I I 3 -36 i

Introduction Each year, the results of the Radiological Environmental Monitoring Program (REMP) are evaluated with consideration of 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. This report not only presents the data collected during the 2011 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 radionuclide detection.

B. 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.Smaller units of the curie are used in this report. Two common units are the microcurie (uCi), which is one millionth (0.000001) of a curie, and the picocurie (pCi), which is one trillionth (0.000000000001) of a curie. The picocurie is the unit of radiation that is routinely used in this report. 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.C. 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 the possible biological damage resulting from exposure to any 5-1 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.

D. 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).

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:** Tritium (H-3), present as a result of the interaction of cosmic radiation with the upper atmosphere.

0 Beryllium-7 (Be-7), present as a result of the interaction of cosmic radiation with the upper atmosphere e Potassium-40 (K-40) and Radium-226, naturally occurring radionuclides found in the human body and throughout the environment Be-7 and K-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 wds signed. Since the treaty, the global inventory of manmade radioactivity in the environmenit 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 wyeapons:tests have been conducted by the People's Republic of China and underground Weapons testing'b.ij 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 (Cs-137)and Strontium-90 (Sr-90). The highest weapons testing concentrations were noted in samples 5-3 I 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 related to nuclear power technology.

These radionuclides are the byproduct of the operation of light water reactors.

These byproduct radionuclides are the same as those produced in atmospheric weapons testing and have been found in the Chernobyl and Fukushima Daiichi Nuclear Power Station fallout. This commonality makes a determination of the source of these radionuclides that may be detected in environmental samples difficult to determine.

During 2011, 1-131 was detected in REMP samples and has been attributed to the trans-Pacific transport of airborne releases from Fukushima Daiichi Nuclear Power Stations fallout following the Tohoku earthquake and is not related to the operations of NMP1 or NMP2. There were no other plant-related radionuclides detected in the REMP samples collected during 2011. 5 A number of factors must be considered in performing radiological sample data evaluation and interpretation.

An attempt has been made not only to report the data collected during 2011, but n 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 i very small and are of no or little, significance from an environmental or dose to man perspective.

3 The 2009 per capita average dose was determined to be 620 mrem 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 mrem per year. The per capita radiation dose from nuclear power production nationwide is less than one mrem per year.The naturally occurring gamma radiation in the environs of the Nine Mile Point site, resulting from 3 radionuclides in the atmosphere and in the ground, accounts for approximately 60-65 mrem 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 Thorium-232 (Th-232).

A dose of 60 mrem per year, as a background I dose, is significantly greater than any possible doses as a result of routine operations at the site during 2011. 5 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 3 findings with a dose to man estimate where appropriate, and an analysis of possible long-term and short-term trends.5-4 During routine. implementation of the REMP, additional or optional environmental pathway media are sampled and analyzed.

These samples are obtained to: o 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" Maintain the analytical data base established when the plants began commercial operation 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 2011 program.Section 7.0, titled Historical Data, 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 four environmental pathways.

These pathways are:* Shoreline Sediment* Fish* Surface Waters* Groundwater Section 6.0, Tables 6-1 through 6-4 present the analytical results for the aquatic samples collected for the 2011 sampling period.Sampling for groundwater, as found in Section D 3.5.1 of the NMP2 ODCM, was not required during 2011. There was no groundwater source in 2011 that was tapped for drinking or irrigation purposes in 5-5 I areas where the hydraulic gradient or recharge properties were suitable for contamination; therefore, groundwater was not a dose pathway during 2011.5.1.1 SHORELINE SEDIMENT RESULTS A. Results Summary I Shoreline sediment samples were obtained in April and October of 2011 at one off-site 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 2011 sample program, two indicator and two control. These results continue to show a downward trend over the past 10 plus years. Cs-137 was not detected in samples collected from the control or indicator locations during 2011. I Historical mean concentrations measured at the Sunset Bay indicator location ranged from a maximum of 0.33 pCi/g in 1993 to a minimum of less than lower limit of detection

(<LLD) in 2011. The results I for the 2011 control location were less than the detection limit. The one naturally-occurring radionuclide detected was K-40, which was not related to plant operations.

No other plant-related radionuclides were detected in the 2011 shoreline sediment samples.The following is a graph of the average Cs-137 concentration in shoreline sediment samples over the previous ten years. This graph illustrates a general downward trend in the Cs-137 concentrations since 2001.I Shoreline Sediment Cs-I137 1.U.U0 0.08 0.07 0.06 0,05 0,04 0.03 0.02 0.01 0 I MCC ntrol N Indicator Note: Years with values of less than the lower limit of detection are presented as zero In the graph.2004 2005 2006 2007 2008 2009 2010 2011 Year 5-6 I I 2001 2002 2003 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 2011. The results of these sample collections are presented in Section 6.0, Table 6-1, Concentrations of Gamma Emitters in Shoreline Sediment Samples -2011. K-40 was the only significant radionuclide detected in the sediment samples.C. Dose Evaluation The calculated potential whole body and skin dose 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 ytear can be calculated.

The following regulatory guide values and the maximum 2011 shoreline sediment indicator Cs-137 concentration were used in calculating the dose to man:* A teenager spends 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> per year at the beach area or on the shoreline,* The sediment has a mass of 40 kg/m 2 (dry) to a depth of 2.5 cm;'* The shoreline width factor is 0.3, and* The maximum 2011 Cs-137 concentration of <0.106,pCi/g (dry) (<LLD).Using these conservative parameters, the potential dose to the maximum exposed individual (teenager) would be 0.00036 mrem/year to the whole body and 0.00042 mrem/year to the skin.This calculated dose is very small and is insignificant when compared to the natural background annual exposure of approximately 48 mrem as measured by control TLDs in the vicinity of the site.D. Data Trends Cs-137 was not detected at the indicator or the control samples locations in 2011. The average Cs-137 concentration (LLD) for the Shoreline sediment indicator sample for 2011 was <0.091 pCi/g (dry). This is consistent with mean concchtratioh-measured at the indicator location over the past ten years.The previous five years of data show a general dedreasing~mean concentration values measured at the indicator locations.

Over the five year period, mean concentrations ranged from a high of 0.08 pCi/g (dry) in 2005 to a low value of 0.04 pCi/g (dry) measured in 2007. Cesium-137 was not detected in the control location samples over this same five-year period.5-7 I The general absence of Cs-137 in the control samples is attributed to the differences in the sediment types between the two sample locations.

Few shoreline regions west of the site contain l fine sediment and/or sand that are characteristic of the indicator location.

It is difficult to obtain control samples that are comparable in physical and chemical characteristics to the indicator samples. Other factors, which include changing lake level and shoreline erosion, further I complicate attempts at consistency in shoreline sediment sampling.

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 the shoreline sediment samples collected in the past. The Cs-137 is commonly found in soil samples and is attributed to weapons testing fallout. Shoreline samples containing soil or sediment are likely to contain Cs-137. 3 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 i period of 2001 through 2010, mean concentrations at the indicator location ranged from a maximum of 0.08 pCi/g (dry) in 2005 to a minimum of 0.04 pCi/g (dry) measured in 2004 and again in 2007. Cs-137 was not detected at the indicator location for 2008 thru 2011. This continues I to support the long-term decreasing trend in Cs-137 concentration in shoreline sediment samples.Cesium- 137 was not detected in the control samples collected over the previous ten years. i Shoreline sediment sampling at the indicator location commenced in 1985. Prior to 1985, no data was available for long-term trend analysis.

.I Section 7.0, Tables 7-1, Historical Environmental Sample Data, Shoreline Sediment (Control) and 7-2, Historical Environmental Sample Data, Shoreline Sediment (Indicator), illustrate historical environmental data for shoreline sediment samples.5.1.2 FISH SAMPLE RESULTS A. Results Summary 3 A total of 18 fish samples were collected for the 2011 sample program. Species collected were: smallmouth bass, brown trout, chinook salmon and walleye. The analytical results for the 2011 fish samples showed no detectable concentration of radionuclides 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 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 2011 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 chain.The 2011 results are consistent with the previous years' results in that they continue to support the I general long-term downward trend in fish Cs-137 concentrations over the last 34 years. Cs-137 5-8 I was not detected in fish samples collected in 2003 to 2011 from indicator locations.

The period of 2001 through 2011 as a group are the lowest results measured since the beginning of the Site Environmental Monitoring Program in 1969.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, Concentration of Gamma Emitters in Fish Samples- 2011, shows individual results for all the samples collected in 2011 in units of pCi/g (wet).The spring fish collection was made up of 9 individual samples representing three separate species.Walleye, smallmouth bass and brown trout were collected.

The total fall fish collection was comprised of 9 individual samples representing three individual species. Chinook salmon, smallmouth bass and brown trout were collected.

Cs-137 was not detected in any of the fish species collected for the 2011 sample program.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. 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. The lack of detectable concentrations of plant-related radionuclides in the 2011 fish samples demonstrates that there is no attributable dose to man from operations at the site through the aquatic pathway.D. Data Trends The Cs-137 data for fish samples over the previous five years (2006 through 2010) show that the number of positive detections has decreased over this period relative to historical data. There were no positive detections of Cs-137 over the previous five-year period at the indicator locations.

The graph below illustrates the mean control and indicator Cs-137 concentrations for 2011 and the previous ten years.5-9 Annual Mean FIsh Cs-137 Concentrations 0,018 0.016 F mControl aIndcator 0.014 Note: Years with values of less than the 0.012 lower limit of detection are presented as 0.01 zero in the graph.IL 0.008 0.006 0.004 0,002 0 Y80ar The ten-year data trend shows a consistent decrease in the level of Cs-137 measured in fish between 2001 and 2011. The 2001 through 2011 results, as a group, are the lowest Cs-137 concentrations measured over the existence of the sample program.The general long-term decreasing trend for Cs-137, illustrated in the following graph, is most probably a result of the cesium becoming unavailable to the ecosystem due to ion exchange with soils and sediments and radiological decay. The concentrations of Cs-137 detected in fish since 1976 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.Section 7.0, Tables 7-3, Historical Environmental Sample Data, Fish (Control) and 7-4, Historical Environmental Sample Data, Fish (Indicator), show the historical environmental sample data for fish.I I I I i I I I I I I i I I I I I I Fish Cs-137 1.4 EControl Mludicator 1.2 Note: Years with values of less than the lower limit I of detection are presented as zero in the graph.0.8 0.6 0.4 0.2 J Year 5-10

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 Generating 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 Nine Mile Point Unit 1 (NMP 1)Intake and the Nine Mile Point Unit 2 (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 2011 Sampling Program. The two nattirally-occurring radionuclide detected were K-40 and Ra-226 and were not related to plant operations.

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 of 20 samples were analyzed for tritium as part of the 2011 REMP program. The results for the 2011 samples showed no positive detection for tritium in samples taken during 2011.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 2011 samples. This is consistent with historical data, which has not shown the presence of plant-related radionuclides in surface water samples.Tritium samples are quarterly samples that are a composite of the applicable monthly samples for a given location.

Tritium samples' analyzed for the 2011 sample program were analyzed to an instrument detection level of 500 pCi/l.The ODCM required indicator location (JAFNPP inlet canal) showed no positive detections of tritium.The 2011 results had LLD values that ranged from <410 pCi/l to <432 pCi/l. The ODCM control location (Oswego Generating Station inlet canal) results showed no positive' detections, and the sample results had LLD values in the range of <412 pCi/l to <432 pCi/l.Tritium was not detected in any of the twelve optional Lake Ontario samples collected in the 2011 program.The Oswego City Water 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 7.8 miles west of the site in an "up-stream" direction based on the current patterns in the lake.5-11 The following table provides the specific results for the 2011 sample program: Sample Location Tritium Concentration pCi/liter Minimum Maximum Mean (Annual)JAFNPP Inlet (Indicator)*

<410 <432 * <419.Oswego Generating Station Inlet (oto) <412 <432 " <419 (Control)*

NMP1 Inlet <417 <432 <419 NMP2 Inlet <412 <432 <419 Oswego City Water Supply <412 <450 <428 Sample location required by ODCM The LLD values are below the ODCM required LLD of 3000 pCi/1 for a non-drinking water pathway.Analytical results for surface water samples are found in Section 6.0, Table, 6-3,.

." The radiological impact to members: 6fithe 0ublc from low levels of tritium in water is insignificant.

This-can .be illustrated by calculatifig., dose to- the -whole botay-and maximum organ using the maximum LLD value and Regulatory Guidel. 109 methodology.

Based on a water ingestion rate of 510 liters/yr and the maximum 2011 LLD concentration of <450 pCi/l, the calculated dose would be less than 0.045 mrem to the child whole body and less than 0.045 mrem to the child liver (critical age group/organ).

D. Data Trends There are no data trends for gamma-emitters such as Cs-137 and Co-60, as historically these radionuclides have not been detected in lake water samples.Tritium results for the 2011 lake water samples were consistent with results from the previous five-years for both the indicator and control locations.

The mean measured tritium concentrations for the previous five-year period of 2006 to 2010 was <LLD pCi/l for the control and the indicator location.The mean 2011 tritium concentrations were <419 pCi/l for the control and <419 pCi/l for the indicator locations.

The previous five-year data indicates no significant trends in either the indicator or the control mean concentrations.

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, 2001 through 2010, are representative of natural variations in environmental tritium concentrations with no significant levels of tritium measured.

The 1999 mean control value of 337 pCi/I is the highest concentration 5-12 I I I I I I I I I I I I I I I I I measured since 1989 and is within the variability of results measured over the life of the program. The ten-year historical results are consistent between the control and indicator locations with no large variation in the measured results.The following graph illustrates the concentrations of tritium measured in Lake Ontario over the previous 21 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 Generating Station, the current control location.Surface Water Tritium 500 450 Note: Years with vw 400 detection are prese 350 300 250 200 150 100 50 0 a, a, 0, ON 0% 0% a, 0 0 0 0 0 10 0 0'ear N 0% 0 Year Section 7.0, Tables 7-5, Historical Environmental Sample Data Surface Water (Control) and 7-6, Historical Environmental Sample data Surface Water (Indicator), show the historical environmental sample data for surface water Co-60 and Cs-137.

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 3.3-1.5-13 U A total of 44 tritium samples were collected for the 2011 sample program using ten indicator locations and three control locations.

All samples results for 2011 groundwater monitoring program were less than the LLD for tritium. i A total of 86 samples were collected for plant-related gamma-emitters, and thirteen strontium-90 (Sr-90) samples were collected for the 2011 sample program using ten indicator locations and three i control locations.

All samples results for 2011 groundwater monitoring program were less than the LLD for plant-related gamma-emitters and Sr-90.B. Data Evaluation and Discussion Plant related gamma-emitters and strontium-90 analysis were performed on samples from the indicator i and control locations.

No plant-related radionuclides were detected in the 2011 samples. This is consistent with historical data, which has not shown the presence of plant-related radionuclides in groundwater samples.Tritium samples analyzed for the 2011 sample program were analysed to a lower limit of detection i of 500 pCi/l. The tritium results for the control locations had LLD values that ranged from <386 pCi/I to <424 pCi/l. The indicator locations results ranged from <407 pCi/1 to <430 pCi/l.C. Dose Evaluation Sampling for groundwater, as found in Section D 3.5.1 of the NMP20DCM, was not required during 2011. There was no groundwater source in 2011 that was 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 2011.D. Data Trends There are no data trends for gamma-emitters or Strontium-90 as these radionuclides have not been detected in groundwater samples. l Groundwater tritium results are documented in the Annual Radiological Effluent Release Report for 2011. Historical data for groundwater tritium is presented in Section 7.0, Tables 7-9, Historical Environmental Sample Data, Surface Water Tritium (Control) and 7-10, Historical Environmental Sample Data, Surface Water 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, and* Food Products.Section 6.0, Tables 6-5 through 6-12 present the analytical results for the terrestrial samples collected for the 2011 reporting period.5.2.1 AIR PARTICULATE GROSS BETA A. Results Summary Weekly air samples were collected and analyzed for particulate gross beta particulate activity.

For the 2011 program, a total of 52 samples were collected from control location R-5, and 208, samples were collected from indicator locations R-1, R-2, R-3, and R-4. 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 (R-5) in 201 1 was 0.0 18 pCi/m 3.The mean gross beta concentration for the samples collected from the indicator locations (k-I, R-2, R-3, and R-4) in 2011 was 0.018 pCi/m 3.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. The indicator results are consistent.

with concentrations measured over the last twenty years. This consistency demonstrates that the natural baseline gross beta activity has been reached. The man-made radionuclide contribution to the natural background from atmospheric weapons testing and Chernobyl can no longer be detected above the background concentrations of naturally occurring beta-emitting radionuclides.

B. Data Evaluation and Discussion The air monitoring system consists of fifteen sample locations, six on-site and nine off-site.

Each location is sampled weekly for particulate gross beta activity.

A total of 780 samples were collected and analyzed as part of the 2011 program. Five of the nine off-site locations are required by the ODCM. These locations are designated as R-1, R-2, R-3, R-4, and R-5. R-5 is a control location required by the ODCM and is located beyond any local influence from the site. In addition, optional off-site and on-site air sample locations are maintained from which weekly samples are collected.

The optional off-site locations are designated as D-2, E, F and G. The optional on-site locations are designated as D-l, G, H, I, J and K.5-15 I I Gross beta analysis requires that the samples be counted no sooner than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 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.

-2011, present the weekly gross beta activity results for samples collected from the off-site and on-site locations.

The mean annual gross beta indicator concentrations for the ODCM indicator stations (R-1, R-2, R-3 and R-4) was 0.018 pCi/m 3.The off-site ODCM control station (R-5) annual mean gross beta concentration was 0.018 pCi/m 3.The minimum, maximum and average gross beta results for sample locations required by the ODCM were as follows: I Concentration pCi/m3 Minimum Maximum Location Mean R-1 0.007 0.033 0.018 R-2 0.007 0.032 0.017 R-3 0.008 0.034 0.018 R-4 0.008 0.033 0.018 Summary (RI -R4) 0.007 0.034 0.018 R-5 (Control) 0.008 0.034 0.018 The mean weekly gross beta concentrations measured in 2011 are illustrated in the following graphs: I I I I I I I I I I I I I I I I Air Particular Filter -Gross Beta (2011)A ..-....--Indicator

~ -Control Week No.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 1980.5-17 I The mean gross beta concentrations measured in 1977 to 2011 are illustrated in the following graph: I Air Particulate Filter -Gross Beta 0.18 0.16 0.14 0.12 0.1 0.08 0.06 0.04 0.02 0*Control KIndicator 1980AtmosphRbc Nuclear Tests 1986 Chernobyl Yea" The trend for the previous five years represents a base line concentration or natural background level for gross beta concentrations.

This trend is stable with minor fluctuations due to natural variations.

5.2.2 AIRBORNE

RADIOIODINE(I-131)'

A. Results Summary From 1987 through 2010, no radioiodine (1-131) has been measured offsite at any of the air monitoring stations.During the 2011 air sampling program, airborne radioiodine wasAdetected, in 15 of the 260 weekly samples collected at the five sampling stations required by the ODCM.'7 1-131 was detected at both the indicator and control stations during the weeks of March 29; April 5, and April 12. The measurable 6oncentrations of I-.1,31 are attributed to fallout from the Fukushima Daiichi Nuclear Power Station event that occufred on March 11, 2011 and not operations at the site. Observed detectable concentrations of 1-131 ranged from 0.031 to 0.11 pCi/m 3 for the indicator stations, and 0.034 to 0.093 pCi/m 3 for the control station.1-131 was also detected in 30 of the 515 weekly samples collected from the ten optional sampling stations.

The positive detections of 1-131 were observed during the same weeks of March and April as noted above for the ODCM required stations.

These measurable concentrations of 1-131 are also attributed to fallout from the Fukushima Daiichi Nuclear Power Station event. Observed detectable concentrations of 1-131 ranged from 0.025 to 0.111 pCi/m 3 for the ten optional onsite and offsite stations.B. Data Evaluation and Discussion Airborne radioiodine (1- 131) is monitored at the fifteen air sampling stations also used to collect air par-ticilate samples. There are nine off-site' locations, five of which are required by the ODCM.The off-site locations required by the ODCM are designated as R-1, R-2, R-3, R-4 and R-5. R-5 is a control station located beyond any local influence from the plant: Ten air sampling locations are also maintained in addition to those required by the ODCM. Six of these stations D-1, G, H, I, J and K are located on-site. D-2, E, F and G are the optional stations located off-site.

Samples are collected using activated charcoal cartridges and analyzed weekly for 1-131. 1-131 was detected in 45 of the 780 samplescollected during 2011.The analytical data for radioiodine are presented in Section 6.0, Tables 6-7, Environmental Charcoal Cartridge Samples -Offsite Sample Locations

-2011 and 6-8, Environmental Charcoal Cartridge Samples -- Onsite Sample Locations

-2011.C. Dose Evaluation The 1-131 sampling program demonstrated no offsite dose to man from this pathway as a result of operation of the plants located at Nine Mile Point.5-19 I I The impact of 1-131 concentrations as a result of the Fukushima Daiichi Nuclear Power Station fallout can be assessed by projecting a maximum organ dose (thyroid) and whole body dose to the critical individual.

The critical individual, in this case, would be a child. Using standard Regulatory Guide I 1.109 methodology and an inhalation rate of 3700 m 3 per year, the thyroid and whole body doses were calculated.

The calculated doses due to the average 1-131 concentration from the indicator stations (0.055 pCi/m 3)were 0.05 mrern/yr to the thyroid and 8.6 E-05 mrem/yr to the whole body of the above mentioned critical individual.

The calculated doses due to the average 1-131 concentration from the control station (0.055 pCi/m 3) were 0.05 mrem/yr to the thyroid and 8.6 E-05 mrem/yr to the whole body. The I calculated doses from the indicator stations and control station were identical.

The calculated dose is very small when compared to the natural background annual exposure of 3 approximately 50 mrem as measured by control TLDs in the vicinity of the site.D. Data Trends In 2011, 1-131 was detected at all 15 sampling locations over a three week period. The positive detections were the result of the trans-Pacific transport of airborne releases from Fukushima Daiichi I Nuclear Power Station fallout following the Tohoku earthquake.

No radioiodine had been detected in samples collected from the air sampling locations required by 3 the ODCM since 1987 until 2011.There has been no positive detection of 1-131 in air samples collected over the last ten years that could be attributed to the operation of the Nine Mile Point Site. This demonstrates that there is no measurable environmental impact Or positive trend for iodine buildup due to plant operations during the period from 2001 through 2011. 1-131 has previously been detected in samples I collected during the last twenty five year period in 1986 and 1987. The 1986 detection of 1-131 was the result of the Chernobyl accident, the 1987 detection was the result ofplant operations and the 2011 detection of 1-131 was the result of the Fukushima Daiichi Nuclear Power Station accident.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/mr 3 , and further decreased by a factor of ten to 0.03 pCi/m 3 in 1978. 1-131 was not detected in samples n 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/m 3.1-131 has been detected in samples collected from the on-site indicator locations during 1976 to 1978, 1980 to 1983, 1986 to 1987 and 2011. The mean concentrations ranged from 0.013 pCi/m 3 in 1980 to a maximum of 0.33 pCi/m 3 in 1976. The maximum mean indicator 1-131 concentration of 0.33 pCi/m 3 was the result of the atmospheric nuclear testing. The Chernobyl accident resulted in 1-131 being detected in a total of 75 weekly samples collected during the 1986 sample program.The 1986 measured concentrations ranged from a minimum of 0.023 pCi/m 3 to a maximum of 0.36 pCi/m 3.Each positive detection of 1-131 in samples collected in 1986 was the direct result of the 5-20 I Chernobyl Nuclear accident.

The Fukushima Daiichi Nuclear Power Station accident resulted in I-131 being detected in a total of 3 weekly samples collected during the 2011 sample program. The 2011 measured concentrations ranged from a minimum of 0.021 pCi/m 3 to a maximum of 0.11 pCi/rm 3.Each positive detection of 1-131 in samples collected in 2011 was the direct result of the Fukushima Daiichi Nuclear Power Station accident.Historical data for 1-131 are presented in Section 7.0, Tables 7-15, Historic Environmental Sample Data, Air Radioiodine (Control) and 7-16, Historic Environmental Sample Data, Air Radioiodine (Indicator).

5.2.3 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; four are located off-site near the site boundary, and one is located off-site 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 air monitoring stations provide 780 individual air particulate samples that are assembled by location into 60 monthly 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 2011.The, gamma analysis results for the quarterly composite samples routinely showed positive detections of Be-7,.K-40, and Ra-226. Each of these radionuclides is naturally occurring.

B. Data Evaluation Discussion A total of fifteen air sampling stations are in continuous operation and located both on-site and in the off-site sectors surrounding the Nine Mile Point site. Five of the fifteen monitoring stations are required by the ODCM, and the remaining ten are optional to provide an effective monitoring network. Composite air filter samples are assembled for each of the fifteen sampling locations.

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 R-1, R-2, R-3, R-4 and R-5. Other sample locations not required by the ODCM, for which analytical results have been provided, include six on-site locations and four off-site locations.

The analytical results for the 60 air particulate filter composites in 2011 showed no detectable activity, of plant related radionuclides.

5 -21 The results of the quarterly composite samples are presented in -Section 6.0, Table 6-9, Concentration of Gamma in Quarterly Composites of JAFNPP/NMPNS Site Air Particulate Samples -2011.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 2011. The monthly air particulate sampling program demonstrated .no off-site dose to man from this pathway as a result of operations of the plants located at the Nine Mile Point site.D. Data Trends i No plant-related radionuclides were detected during 2011 at the off-site air monitoring locations.

3 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 off-site 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 NMP1 facility.

There have been no subsequent measurable concentrations of Co-60 in the environment surrounding the Nine Mile Point site. 3 Historical data shows that cesium-137 (Cs-137) is the fission product radionuclide most frequently detected in the air particulate filter composites.

Cs-137 was detected in each of the years from 1977 through 1983 at both the control and indicator sampling locations.

The presence of Cs-137 in the air samples collected during these years was the result of atmospheric, weapons testing. Cs-137 3 was again detected in 1986 as a result of the Chernobyl accident.

Since 1986 there have been no detections of Cs-137 in the environment surrounding the Nine Mile Point site.After 1986, no plant-related or fallout radionuclides were detected in any of the off-site air I particulate composite samples with the exception of the isolated detection of Co-60 in 2000 in a single sample. A review of the past five years' data for air particulate filter composites indicates i no plant related radiological impact on the environment.

All previous historical positive detections of fission product radionuclides were associated with atmospheric weapons testing or the Chernobyl accident, with the exception of the 2000 detection noted above. i Historical data for air particulate results are presented in Section 7.0, Tables 7-13, Historic Environmental Sample Data, Air Particulate (Control) and 7-14, Historic Environmental Sample I Data Air, Particulate (Indicator).

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 2011 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 2011. 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: " On-site (areas within the site boundary:

TLDs 3, 4, 5, 6, 7, 23, 24, 25, and 26; TLDs 18, 27, 28, 29, 30, 30, 31, 39, 47, 103, 106, and 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 direct shine, TLDs 7, 18, 78, 79, 80, 81, 82, 83, and 84; TLDs 23, 75, 76, 77, 85, 86, and 87 are excluded)* Off-site Sector (area four to five miles from the site in each of the eight land based meteorological sectors: TLDs 88, 89, 90, 91, 92, 93, 94, and 95)" Special Interest (areas of high population density and use: TLDs 15, 56, 58, 96, 97 and 98)" Control (areas beyond significant influence of the site! TLDs 14 and 49)All geographical locations are required by the ODCM with the exception of the On-site area which was optional.

Description of the five geograpical categories and the designation of specific TLD locations that make up each category is presented in Section 3.1.6, TLD (Direct Radiation) of this report. A summary of the 2011 dose rates for each of the five geographical locations is as follows: Dose inmrem per standard month Geographic Category Minimum Maximum Mean On-site (Optional) 3.1 13.0 5.1 Site Boundary (Inner Ring) * () 3.1 5.3 4.1 Off-site Sectors (Outer Ring)

• 3.0 5.3 4.0 Special Interest * (2) 2.9 4.9 4.0 Control*(3) 2.6 4.7 3.8* Geographical locations required by the ODCM 1 Only includes TLD results that are not affected by radwaste direct shine (TLDs. 7, 18, 78, 79, 80, 81, 82, 83, and 84)2 Only includes TLD results required by the ODCM (TLDs 15, 56, 58, 96, 97, and 98)3 Only includes TLD results required by the ODCM (TLDs 14 and 49)5-23 I 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 I measured at the site boundary and control locations.

The results for the Site Boundary, Off-site Sectors and Special Interest (Off-site) were well within expected normal variation when compared to the Control TLD results.The results for the 2011 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 systems used at 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 2011, 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: On-site, Site I Boundary, Offsite by Sector, Special Interest, and Control locations.

All categories are required by the ODCM with the exception of the On-site TLDs. On-site TLDs are placed at various locations within the site boundary to provide additional information on direct radiation levels at and around the NMP1, NMP2 and JAFNPP facilities.

On-site TLDs are optional and are subdivided into three categories for which direct radiation results are evaluated.

The 2011 direct radiation results for On-site TLD locations were as follows: 1. Results for TLDs located near the NMP1, NMP2 and JAFNPP facilities and at previous or existing on-site air monitoring stations ranged from 3.1 to 13.0 mrem per standard month.2. Results for TLDs located near the north shoreline of NMP1, NMP2 and JAFNPP in close proximity to the Radwaste and NMP1 Reactor Building ranged from 2.6 to 28.8 mrem per standard month.3. Results for TLDs located on-site near the Energy Information Center and its associated shoreline ranged from 3.9 to 6.0 mrem per standard month.Site Boundary TLD results ranged from 3.3 to 11.6 mrem per standard month in 2011. This range included all TLDs placed in each of the 16 meteorological sectors in the general area of the site boundary.

The highest dose rate measured at a location required by the ODCM was 11.6 mrem per standard month. This TLD, (TLD 85) represents the site boundary maximum dose and is located in i the WNW sector along the lake shore in close proximity to the NMP 1 plant. The TLD locations along the lakeshore close to the plants (TLDs 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 I public, and the TLD results for these areas are not representative of dose rates measured at the 5-24 i remaining site boundary locations.

The remaining Site Boundary TLD locations, which are located away from the plant ranged from 3.1 to 5.3 mrem per standard month resulting in an average dose* rate of 4.1 mrem per standard month.* Off-site 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 3.0 to 5.3 mrem per standard month with an average dose rate of 4.0 mrem per standard month.Special Interest TLDs from all locations ranged from 2.9 to 4.9 mrem per standard month with an annual average dose rate of 4.0 mrem per standard month.The Control TLD group required by the ODCM utilizes locations positioned well beyond the site.2011 Control TLD results ranged from 2.6 to 5.5 mrem per standard month with an annual average dose rate of 4.0 mrem per standard month. These results include both the ODCM required control TLDs (14 and 49) and the additional controlTLDs (8, 111 and 113).TLD analysis results are presented in Section 6.0, Table 6-10, Direct Radiation Measurement Results -2011.C. Dose Evaluation 2011 annual mean dose rates for each geographic location required by the ODCM are as follows: Site Boundary:

4.1 mrem per standard month (TLDs: 78, 79, 80, 81, 82, 83, 84, 7 and 18)Off-site Sectors: 4.0 mrem per standard month (TLDs: 88, 89, 90, 91, 92, 93, 94 and 95)Special Interest:

4.0 mrem per standard month (TLDs: 15, 56, 58, 96, 97 and 98)Control: 3.8 mrem per standard month (TLDs 14 and 49)The measured mean dose rate in the proximity of the closest resident was 4.2 mrem per standard month (TLD #s: 108, 109), which is consistent with the control measurements of 3.8 mrem 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 off-site environment.

5-25 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 off-site 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, Off-site 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, Off-site Sectors and Special Interest groups from 2002 through 2011: TLD Data 5 4 3I I I I I I I I I I I I I I I I I I I 0 Year TLDs located at the site boundary averaged 4.1 mrem per standard month during 2011 (Site Boundary average results do not include TLDs influenced by radwaste buildings and radwaste shipping activities).

This result is consistent with the previous five year average of 4.1 mrem per standard month.Off-site Sector TLDs averaged 4.0 mrem per standard month during 2011. This result is also consistent with the previous five-year average of 4.0 mrem per standard month for off-site sectors.Special Interest TLD locations averaged 4.0 mrem per standard month during 2011 which is consistent with the previous five-year average of 4.0 mrem per standard month.The last group of TLD locations required by the ODCM is the Control Group. This group utilized TLD locations positioned well beyond the site. 2011 control results from all Control TLDs averaged 3.8 mrem per standard month, consistent with the previous five-year average of 4.1 mrem 5 -26 per standard month. The 2011 TLD program results, when compared to the previous ten years, showed no significant trends relative to increased dose rates in the environment.

Section 7.0, Tables 7-17 through 7-22 show the historical:

environmental sample data for environmental TLDs.5.2.5 MILK A. Results Summary A total of 36 milk samples were collected during the 2011 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 2011 from the two milk sample locations.

".The 2011 :results' demonstrate'thaf 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 milch animal census, there were no adequate .milk sample locations within five. miles of the site in 2011.Samples were collected from two farms located beyond the five-mile requirement to ensure the continued monitoring of this important pathway. The indicator location is approximately 9 miles east from the site. The control samples were collected from a farm located 16.0 miles from the site and inia 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)

SSW 16.0 5 -27' Samples were collected from Indicator location #55 and Control location #77 from April through December.

Sampling occurs during the first and second half of each month. Samples were not required to be collected during January through March of 2011 as a result of 1-131 not having been detected in samples collected during November and December of 2010, as stipulated in the ODCM.C. Data Evaluation and Discussion Each milk sample is analyzed for gamma-emitters using gamma spectral analysis.

The 1-131 analysis is performed using resin extraction followed by spectral analysis for each sample. 1-131 and gamma analysis results for milk samples collected during 2011 are provided in Section 6.0, Table 6-11, Concentration of Iodine-131 and Gamma Emitters in Milk- 2011.Iodine 131 was not detected in any indicator or control milk samples analyzed during 2011. 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 2011. 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. Cs-137 was not detected in any indicator or control milk sample collected in 2011.The results of the milk samples are presented in Section 6.0, Table 6-11, Concentration of Iodine-131 and Gamma Emitters in Milk 2011.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 K-40.E. Data Trends Man-made radionuclides are not routinely detected in milk samples. In the past twenty five years, Cs-137 was only detected in 1986, 1987, and 1988. The mean Cs-137 indicator activities for those years were 8.6, 6.8 and 10.0,pCi/liter, respectively.

1-131 was measured in two milk samples collected in 1997 from a single indicator sample location, having a mean concentration of 0.50 pCi/liter and was of undetermined origin. The previous detection was in 1986 with a mean 5-28 concentration of 13.6 pCi/liter in a control location.

The 1986 -1988 activity was a result of the Chernobyl accident.The comparison of 2011 data to historical results over the operating life of the plants shows that Cs-137 and 1-131 levels in milk have decreased significantly since the 1980's.Historical data of milk sample results for Cs-137 and 1-131 are presented in Section 7.0, Tables 7-23, Historical Environmental Sample Data, Milk (Control) and 7-24, Historical Environmental Sample Data, Milk (Indicator).

5.2.6 FOOD PRODUCTS (VEGETATION)

A. Results Summary There were no plant-related radionuclides detected in the 14 food product samples collected and analyzed for the 2011 program.Detectable levels of naturally occurring K-40 were measured in all control and most of the indicator samples collected for the 2011 program. Be-7 a naturally-occurring radionuclide, was also detected intermittently in samples collected in 2011. These results are consistent with the levels measured in previous years.The results of the 2011 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 five 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 miles away in a predominately upwind direction.

Food product samples collected during 2011 did not include any varieties considered to be edible broadleaf vegetables.

The general lack of edible broadleaf vegetation samples was the result of grower preference and such varieties were not available in local gardens. Where broadleaf vegetables were not available, non-edible broadleaf vegetation was collected.

Non-edible vegetation consisting of brussel sprout leaves, corn leaves, horseradish leaves, rhubarb leaves, tomatoes leaves, cabbage leaves, grape leaves and squash leaves were collected for the 2011 program. 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.

At least one sample from each garden location was analyzed for Carbon-14.

5-29 The analysis of food product samples collected during 2011 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 and K-40 were detected in food product samples. The results for naturally-occurring radionuclides are consistent with the data of prior years. I Analytical results for food products are found in Section 6.0, Table 6-12, Concentration of Gamma Emitters and C-14 in Food Products -2011. I C. Dose Evaluation 3 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 I measurable off-site dose to man from this pathway as a result of operations of the plants located at the Nine Mile Point site.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 of 0.008 pCi/g (wet). i Historically, Cs-137had 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 1979. The trend for Cs-137 is a general reduction in concentration to non-detectable levels in samples collected during the 2001 through 2011 sample programs.Historical data of food product results are 'presented in Section 7.0, Tables 7-25, Historical Environmental Sample Data, Food Products (Control) and 7-26, Historical Environmental Sample Data, Food Products (Indicator).

5.2.7 LAND USE CENSUS RESULTS A. Results Summary 3 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 2011, a milk animal census, a nearest resident census, and a garden census were performed.

5-30 The results of the closest residence census conducted in 2011 required no change to either the* NMP I or NMP2 ODCMs' closest resident location.A garden census, not required by the ODCM, is performed to identify appropriate garden sampling locations and dose calculation receptors.

Garden samples were collected from a number of locations listed in Table 5-1 of the NMP1 and NMP2 ODCMs and identified in the census as active for 2011. See Table 3.3-1 for 2011 sampling locations.

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. The census, covering areas out to a distance of 10 miles exceeds the 5 mile distance required by the ODCM. A resident census is conducted and is designed to identify the nearest resident in each meteorological sector out to a distance of 5 miles.The milk animal census is an estimation of the number of cows and goats within an approximate 10 mile radius of the Nine Mile Point Site. The annual census is conducted during the first half of the grazing season by sending questionnaires to previous milk animal owners and also by road surveys to locate any possible new locations.

In the event the questionnaires are not answered, the owners are contacted by telephone or in person. The local county agricultural extension service is also contacted as an additional source of information concerning new milk animal locations in the vicinity of the site.The number of milk animals located within an approximate 10-mile radius of the site was estimated to be 352 cows and no goats based on the 2011 land use census. The number of cows has decreased by 57, when compared to the 2010 census. The results of the milk animal census are found in Section 6.0, Table 6-13, Milk Animal Census -2011.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 water sectors include: N, NNE, NE, ENE, W, WNW, NW and NNW. The results of the residence census, showing the applicable sectors and degrees and distance of each of the nearest residence, are found in Section 6.0, Table 6-14, Residence Census -2011. There Were no changes identified in the 2011 census for the closest resident in the land based meteorological sectors. The nearest resident locations are illustrated in Section 3.3, Figure 3.3-5.

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 5-31

!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- 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 bodydose 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 results of the 2011 REMP continue to clearly demonstrate that there is no significant short-term or chronic long-term radiological impact on the environment in the vicinity of the Nine Mile Point site. No unusual radiological characteristics were measured or observed in the local environment.

The REMP continues to demonstrate that the effluents from the site to the environment contribute no significant or I 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 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 1980s, the* 1986 accident at the Chernobyl Nuclear Power Plant, and the March 11, 2011 accident at Fukushima Daiichi Nuclear Power Stations.

" The results for the 2011 sample program demonstrate that the concentrations of man-made radionuclides continue to decline. This reduction in environmental background concentrations will allow for the site environmental program to become more sensitive to the measurable impact of plant operations on the environment as time goes on.The REMP did not detect any plant-related radionuclide in the sample media collected during 2011. 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 I 5-32 approximately 50 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 2011 Radiological Environmental Monitoring Program, it can be concluded that the levels and variation of radioactivity in the environment samples were consistent with background levels that would be expected for the lakeshore environment of the site.

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 reported 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.6-1 TABLE 6-1 CONCENTRATIONS OF GAMMA EMITTERS IN SHORELINE SEDIMENT SAMPLES -2011 Results in Units of pCi/kg (dry) +/- 1 Sigma GAMMA EMITTERS Sample Location *** Collection Date K-40 Co-60 Cs-134 Cs-137 Zn-65 Others t 04/25/it 22240 +/- 1124 < 106.6 < 76.0 < 75.7 < 251.5 <LLD Sunset Bay (05) *10/24/11 21330 +/- 1267 < 74.5 < 62.2 < 106.0 < 329.6 <LLD-04/25/11 12500 +/- 905 < 106.0 < 92.6 < 68.1 < 183.9 <LLD Lang's Beach (06, Control)10/24/11 10820 +/- 722 < 48.2 < 48.7 < 49.8 < 146.9 < LLD* Sample Location required by the ODCM Corresponds to Sample Location noted on Figure 3.3-5 t Plant related radionuclides 6-2 I I -M M M M I M M M M I mmmmm m -m m m m m m m m m m m m TABLE 6-2 CONCENTRATIONS OF GAMMA EMITTERS IN FISH SAMPLES -2011 Results in Units of pCi/kg (wet) + 1 Sigma FITZPATRICK

8.0 QUALITY

ASSURANCE

/ QUALITY CONTROL PROGRAM 8.1 PROGRAM DESCRIPTION The Offsite Dose Calculation Manuals (ODCM), for Nine Mile Point Unit 1 (NMP 1) and Nine Mile Point Unit 2 (NMP2), Part II, Section 4.0 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 James A. FitzPatrick Nuclear Power Plant (JAFNPP) Environmental Laboratory has engaged the services of Eckert & Ziegler Analytics, Incorporated in Atlanta, Georgia (Analytics).

Analytics supplies 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 JAFNPP Environmental Laboratory using standard laboratory procedures.

Analytics issues a statistical summary report of the results.The JAFNPP Environmental Laboratory uses predetermined acceptance criteria methodology for evaluating the laboratory's performance.

The JAFNPP Environmental Laboratory also analyzes laboratory blanks. The analysis of laboratory blanks provides a means to detect and measure radioactive contamination of analytical samples. The analysis of analytical blanks also provides information on the adequacy of background subtraction.

Laboratory blank results are analyzed using control charts.8-1

The sample evaluation method is discussed below.8.3.1 SAMPLE RESULTS EVALUATION Samples provided by Analytics are evaluated using what is specified as the NRC method. This method is based on the calculation of the ratio of results reported by the participating laboratory (QC result) to the Vendor Laboratory Known value (reference result).8-2 An Environmental Laboratory analytical result is evaluated using the following calculation:

The value for the error resolution is calculated.

The error resolution

=Reference Result Reference Results Error (1 sigma)Using the appropriate row under the Error Resolution column below, a corresponding Ratio of Agreement interval is given.The value for the ratio is then calculated.

Ratio of Agreement QC Result Reference Result If the value falls within the agreement interval, the result is acceptable.

ERROR RESOLUTION RATIO OF AGREEMENT<4 No Comparison 4 to 7 0.5 to 2.0 8 to 15 0.6 to 1.66'16 to 50 0.75 to 1.33 51 to200 0.8 to 1.25>200 0.85 to 1.18 This acceptance test is generally referred to as the "NRC" method. The acceptance criteria is contained in Procedure EN-CY-102 (JAFNPP).

The NRC method generally results in an acceptance range of approximately

+/- 25% of the Known value when applied to sample results from the Eckert & ZieglerAnalytics Interlaboratory Comparison Program. This method is used as the procedurally required assessment method and requires the generation of a deviation from QA/QC program report when results are unacceptable.
