SUMMARY

The Annual Radiological En vironmental Operating Report is published in accordance with the J.A. Fit z Patrick N.P.P. Offsite Dose Calculation Manual (ODCM), Part I, Section 6.1. The ODCM requires that the results from the Annual Radio logical Environmental Monitoring Program (REMP) be provided to the Nuclear Regulatory Commission by May 15 th of each year.

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

The REMP is a comprehensive surveillance program, which is implemented to assess the impact of site operations on the environment and co mpliance with 10CFR20 , 40CFR190 and 10CFR72. 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 2005 there were 2318 analyses performed on environmental media collected as part of the required monitoring program. These results demonstrated that there is no sign ificant or measurable radiological impact from the operation of the FitzPatrick plant. Cesium-137 was detected in one aquatic pathway (shoreline sed iment) at very low levels and was attributed to fallout from past weapons testing. The 2005 resu lts for al l pathways sampled are consistent with the previous five year historical results and exhibit ed no adverse trends.

In summary, the analytical results from the 2005 Radiological Environmental Monitoring Program demonstrate t hat the routine operation at the James A. FitzPatrick site had no significant or measurable radiological impact on the environment. No elevated radiation levels were detected in the off-site environment as a result of the hydrogen injection program, the storage of radioactive waste, or t he implementation of the Independent Spent Fuel Storage Installation.

The results of the REMP continue to demonstrate that the operation of the plant did not result in a significant measurable dose to a member of the general population, or adversely impac t the environment as a result of radiological effluents. The environmental program continue s to demonstrate that the dose to a member of the public as a result of the op eration of the James A. FitzPatrick Nuclear Power Plant remain s significantly below th e federally required dose limits specified in 10CFR20 , 40CFR190 and 10CFR72.

2.0 INTRODUCTION

The James A. FitzPatrick N.P.P. is owned and operated by Entergy Nuclear

FitzPatrick, LLC (ENF), Entergy Nuclear Operations, Inc. (ENO). This report is

submitted in accordance with Offsite Dose Calculation Manual, Part I, Section 6.1.

This report covers the calendar year 200 5. 2.1 PROGRAM HISTORY Environmental monitoring of the Nine Mile Point site has been on

-going since 1964.

The program includes five years of pre

-operational data, which was conducted prior to any reactor operatio ns. In 1968, the Niagara Mohawk Power Company began the required preoperational environmental site testing program. This pre

-operational data serves as a reference point to compare later data obtained during reactor operation. In 1969, the Nine Mile Poi nt Unit 1 reactor, a 615 Megawatt Boiling Water Reactor (BWR) began full power operation. In 1975, the James A. FitzPatrick Nuclear Power Plant, owned and operated at that time by the New York Power

Authority, began full power operation. The FitzPatrick Plant, an 881 Megawatt (Rated) BWR, occupies the east sector of the Nine Mile Point site, approximately 0.57 miles east of Nine Mile Point Unit 1. In 1988, The Nine Mile Point Unit 2

reactor, also owned and operated by Niagara Mohawk, began full power ope ration. This 1207 Megawatt BWR is located between Unit 1 and FitzPatrick.

In 1985, the individual plant Effluent Technical Specifications were standardized to the generic Radiological Effluent Technical Specifications, much of which was

common to the tw o reactors, and subsequently Nine Mile Point Unit 2. Subsequent Technical Specification amendments relocated the REMP requirements to the ODCM for all three plants. Data generated by the Radiological Environmental

Program is shared, but each utility revi ews and publishes their own annual report. On November 21, 200 0 the ownership and operation of the James A. FitzPatrick N.P.P.

was transferred from the New York Power Authority to Entergy Nuclear FitzPatrick, LLC and Entergy Nuclear Operations Inc. The f acility operating license No. DPR

-59 and Docket No. 50

-333 remained the same. On November 07, 2001, the ownership of the Nine Mile Point Unit I and II facilities was transferred to Constellation Nuclear. These facilities are operated by Nine Mile Point N uclear Station, LLC.

2-2 In summary, three Boiling Water Reactors, which together generate 270 3 Megawatts, have operated collectively at the Nine Mile site since 1988. A large database of environmental results from the exposure pathways have been collected

and analyzed to evaluate the potential impact from reactor operations.

2.2 SITE DESCRIPTION The Nine Mile Point 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 southeast of the site.

The J.A. FitzPatrick generating facility and support buildings occupy a small

shoreline portion of the 70 2 acre Entergy site, which is partially wooded. The land, soil of glacier deposits, rises gently from the lake in all directions. Oswego County is a rural environment, with about 18% of the land devoted to agriculture.

2.3 PROGRAM

OBJECTIVES The objectives of the Radiological Environmental Monitoring Program 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 JAFNPP site.

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

3-1 3.0 PROGRAM DESCRIPTION To achieve the objectives listed in Section 2.3, an extensive sampling and analysis program is conducted every year.

The James A FitzPatrick N

.P.P. (JAFNPP)

Radiological Environmental Monitoring Program (REMP) consists of samplin g and analysis of various media that include:

• Shoreline Sediment

• Fish

• Surface Waters

• Air

• Milk

• Food Products In addition, direct radiation measurements are performed using thermoluminescent dosimeters (TLDs). These sampling programs are outlined in Table 3.0-1. The JAF REMP sampling locations are selected and verified by an annual land use census. The accuracy and precision of the program is assured by participation in an Interlaboratory Comparison Quality

Assurance Program (ICP). In addition to the pa rticipation in the ICP Program, sample splits are provided to the New York State Department of Health for cross checking purposes.

Sample collections for the radiological program are accomplished by a dedicated site environmental staff from both the Nine Mile Point Nuclear Stations (NMP NS) 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).

3-5 NOTES FOR TABLE 3.0

-1 (a) It is recognized that, at times, it may not be possible or practical to obtain samples of the media of choice at the most desired location or time. In these instances suitable alternativ e media and locations may be chosen for the particular pathway in question. Actual locations (distance and directions) from the site shall be provided in the Annual Radiological Environmental Operating

Report. Calculated site averaged D/Q values and mete orological parameters are based on historical data (specified in the ODCM) for all licensed site reactors.

(b) Particulate sample filters should be analyzed for gross beta 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or more after sampling to allow for radon and thoron daughter decay. If g ross beta activity in air is greater than 10 times a historical yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

(c) Gamma isotopic analysis means the identification and quantification of gamma emitting radionuclides that may be attributable to the effluents from the plant.

(d) The purpose of these samples is to obtain background information. If it is not practical to establish control locations in accordance with the distance and wind direction criter ia, other sites, which provide valid background data, may be substituted.

(e) One or more instruments, such as a pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. For the purpose of this table, a thermoluminescent dosimeter may be considered to be one phosphor and two or more phosphors in a pocket may be considered as two or more dosimeters. Film badges shall not be used for measuring direct radiation.

(f) The "upstream sample" shall be taken at a distance beyond significant influence of the discharge.

The "downstream sample" shall be taken in an area beyond, but near, the mixing zone, if practical.

(g) Composite samples should be collected with equipment (or equivalent) which is capable of collecting an aliquot at time intervals which are very short (e.g., hourly) relative to the compositing period (e.g., monthly) in order to assure that a representative sample is obtained.

(h) A milk sampling location, as re quired in Table 3.0

-1, is defined as a location having at least 10 milking cows present at a designated milk sample location. It has been found from past experience, and as a result of conferring with local farmers, that a minimum of 10 milking cows is ne cessary to guarantee an adequate supply of milk twice per month for analytical purposes.

Locations with less than 10 milking cows are usually utilized for breeding purposes, which eliminates a stable supply of milk for samples as a result of suckling calv es and periods when the adult animals are dry. In the event that 3 milk sample locations cannot meet the requirement for 10 milking cows, then a sample location having less than 10 milking cows can be used if an adequate supply of milk can reasonably and reliably be obtained based on communications with the farmer.

3-6 3.1 SAMPLE COLLECTION METHODOLOGY

3.1.1 SHORELINE

SEDIMENTS One kilogram of shoreline sediment is collected at one area of existing or potential recreational value. One sample is also col lected from a location beyond the influence of the site. Samples are collected as surface scrapings to a depth of approximately 1 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, Walle ye 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 off shore from the site. One set of control samples are collect ed at an off-site sample transect located off shore 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 s ample location. Samples selected are limited to edible and/or sport species when available.

b. Samples are composed of 0.5 to 1 kilogram of the edible portion only.

Selected fish samples are frozen immediately after collection and segregat ed by species a nd location. Samples are shipped frozen in insulated containers for analysis. Edible portions of each sample are analyzed for gamma emitting radionuclides. Fish collection locations are shown in Section 3.3, Figure 3.3

-5. 3.1.3 SURFACE WATER Surface w ater samples are taken from the respective inlet canals of the James A.

Fitzpatrick Nuclear Power Plant (JAFNPP) and the NRG's Oswego Steam Station. The JAFNPP facility draws water from Lake Ontario on a continuous

basis. This is used for the "downstream

" or indicator sampling point for the Nine Mile Point site. The Oswego Steam Station inlet canal removes water from Lake Ontario at a point approximately 7.6 miles west of the site. This "upstream"

location is considered a control location because of the distance from the site as well as the result of the lake current patterns and current patterns from the Oswego River located nearby.

3-7 Samples from the JAFNPP facility are composited from automatic sampling equipment which discharges into a compositing tan k or bottles. Samples are collected monthly from the compositor and analyzed for gamma emitters.

Samples from the Oswego Steam Station are also obtained using automatic

sampling equipment and collected in a holding tank. Representative samples from this location are obtained weekly and are composited to form a monthly composite sample. The monthly samples are analyzed for gamma emitting radionuclides.

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

In addition to the sample results for the JAFNPP and Oswego Steam Station collection sites, data is presented for the Nine Mile Point Unit 1 and Unit 2

facility inlet canal samples and from the City of Osw ego drinking water supply.

The latter three locations are not required by the ODCM. These locations are optional sample points, which are collected and analyzed to enhance the surface

water sampling program. Monthly composite samples from these three lo cations are analyzed for gamma emitting nuclides and quarterly composite samples are analyzed for tritium.

Surface water sample locations are shown in Section 3.3 on Figure 3.3

-4. 3.1.4 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 deposition factor (D/Q) based on historical meteorological data. These s tations (R

-1, R-2, and R-3) are located in the E, ESE, and SE sectors as measured from the center of the Nine Mile Point Nuclear Station Unit 2 Reactor Building. The ODCM also require 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 16.2 miles from the site in the NE meteorological sector.

In addition to the five ODCM required locations, there are ten additional sampling stations. Six of these sampling stations are located within the site boundary and

are designated as On

-Site Stations D1, G, H, I, J, and K. These locations are within the site boundary of the NMPNS and JAFNPP. One air sampling station is located Off

-Site in the southwest sector in the vicinity of the City of Oswego and is designated as Station G Off

-Site. Three remaining air sampling stat ions are located in the ESE, SSE, and S SW sectors and range in distance from 7.1 to 9.0 miles. These are designated as Off

-Site Stations D2, E and F respectively.

3-8 Each station collects airborne particulates using glass fiber filters (47 millimeter diamet er) and radioiodine using charcoal cartridges (2x1 inch). The samplers run continuously and the charcoal cartridges and particulate filters are changed on a weekly basis. Sample volume is determined by use of calibrated gas flow meters located at the sam ple 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 monthly by location and analyzed for gamma emitting radion uclides. Air sampling station locations are shown in Section 3.3, Figures 3.3

-2 and 3.3-3. 3.1.5 TLD (DIRECT RADIATION)

Thermoluminescent dosimeters (TLDs) are used to measure direct radiation (gamma dose) in the environment. Environmental TLDs are sup plied and processed quarterly by the Areva/Framatome Environmental Laboratory. The laboratory utilizes a Panasonic based system using UD

-814 dosimeters, which 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.

A. Environmental TLDs Environmental TLDs are placed in five different geographical regions around site to evaluate effects of Direct Radiation as a result of Plant Operat ions. The following is a description of the five TLD geographical categories used in the NMPNS and JAFNPP Environmental Monitoring Program and the TLDs that make up each region:

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

Site Boundary An inner ring of TLD s placed in the general area of the Site Boundary in each of the sixteen meteorological sectors. This category is required by ODCM. (TLD locations comprising this

group are:

7*, 18*, 23*, 75*, 76*, 77*, 78*, 79*, 80*, 81*, 82*, 83*, 84*, 85*, 86*, and 87*)

3-9 TLD Geographical Category Description Off-site Sector An outer ring of TLDs placed 4 to 5 miles from the site in each of the 8 land based meteorological sectors. This category is required

by the ODCM. (TLD locations comp rising this group are 88*, 89*, 90*, 91*, 92*, 93*, 94*, and 95*) Special Interest TLDs placed in Special Interest areas of high population density and use. These TLDs are located at or near large industrial sites, schools, or nearby towns or communit ies. This category is required by the ODCM. (TLD locations comprising this group are: 9, 10, 11, 12, 13, 15*, 19, 51, 52, 53, 54, 55, 56*, 58*, 96*,

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

Control TLDs placed in areas beyond significant influence o f 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*, 14*, 49*, 111, 113)

• TLD location req uired by the ODCM Although the ODCM require a total of 3 2 TLD stations, environmental TLDs are also placed at additional locations, not required by the ODCM, within the On-site, Special Interest and Control TLD categories to supplement the ODCM required d irect radiation readings.

Two dosimeters are placed at each TLD monitoring location. The TLDs are sealed in polyethylene packages to ensure dosimeter integrity and placed in

open webbed plastic holders and attached to supporting structures , such as utili ty poles. Environmental TLD locations are shown in Section 3.3, Figures 3.3

-2 and 3.3-3.

3-10 B. Independent Spent Fuel Storage Installation (ISFSI)

In order to provide adequate spent fuel storage capacity at the FitzPatrick plant, Entergy constructed an Indep endent Spent Fuel Storage Installation (ISFSI) on site. On April 25, 2002, the ISFSI facility was placed in service.

TLDs are used to monitor direct radiation levels in the vicinity of the ISFSI facility. Twelve TLD locations were established around the ISFSI pad on the perimeter fence. Six additional TLD locations are located at varying distances from the pad to determine dose rates at points of interest relative to the storage area and are designated as optional locations. Background data was collect ed starting in October 2000 at eight of the TLD locations on the perimeter fence.

The remaining locations were established in October 2001.

Two dosimeters are placed at each TLD monitoring location. The TLDs are sealed in polyethylene packages to ensure dosimeter integrity and placed in the field using a supporting structure such as a fence or other immovable object. ISFSI TLD locations are shown in Section 3.3, Table 3.3.1.

3.1.6 MILK Milk samples are routinely collected from four farms during the sa mpling year.

These farms include three indicator locations and one control location. Samples are normally collected April through December of the sample year. If plant related radionuclides are detected in samples in November and December of the

previou s 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 sampling year. Milk samples were not collected in January through March of 2005 as there were no positive detections of plant related radionuclides in samples collected during November and December of 2004. The ODCM also requires that a sample be collected from a control location nin e to twenty miles from the site and in a less prevalent wind direction. This location is in the south sector at a distance of 16 miles and serves as the control location.

Milk samples are collected in polyethylene bottles from a bulk storage tank at each sampled farm. Before the sample is drawn, the tank contents are agitated to assure a homogenous mixture of milk and butterfat. Two gallons are sampled from each indicator and control location at each collection. The samples are

chilled, preserved and s hipped 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. (Refer to Section 3.3, Table 3.3

-1 for location designation and descriptio ns.)

3-11 3.1.7 FOOD PRODUCTS (VEGETATION)

Food products are collected once per year during the late summer harvest season.

A minimum of three different kinds of broad leaf vegetation (edible or inedible) are collected from two different indicator garden loc ations. Sample locations are selected from available gardens identified in the annual census that have the highest estimated deposition values (D/Q) based on historical site meteorological data. Control samples are also collected from available locations greater than 9.3 miles distant from the site in a less prevalent wind direction. Control samples are of the same or similar type of vegetation when available.

Food product samples are analyzed for gamma emitters using gamma isotopic analysis. Food prod uct locations are shown in Section 3.3, Figure 3.3

3 - 19 3 - 20 3 - 21 3 - 22 3 - 23 3 - 24 3 - 25 3.4 LAND USE CENSUS The ODCM requires that a milch animal census and a residence census be conducted annually out to a distance of five miles. Milch animals are defined as any animal that is routinely used to provide milk for human consumption.

The milch animal census is an estimation of the number of cows and goats within an approximate ten mile radius of the Nine Mile Point Site. The census is done once per year in the summer. It is conducted by sending questionnaires to previous milch animal owners, and

by road surveys to locate any possible new owners. In the event th at 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 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 ODCM if broadleaf vegetation sampling and analysis are performed.

3 - 26 3.5 CHANGES TO THE REMP PROGRAM The following changes were implemented during the 200 5 sampling program:

A. Food P roduct Samp ling Program During the reporting period, no changes were made to the Environmental Monitoring locations samples to implement the requirements of the ODCM, Part I, Table 5.1

-1. Sample locations selected were based on the 2005 annual land use census. Bas ed on the garden census, food product location 68 was added to the ODCM as a potential sampling location. This sample location was utilized to implement the 2005 food

product sampling requirements.

3 - 29 3.7 STATISTICAL METHODOLOGY There are a number of statistical calculation methodologie s used in evaluating the data from the environmental monitoring program. These methodologies include determination of standard deviation, the mean and associated error for the mean and the lower limit of

detection (LLD).

3.7.1 ESTIMATION

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

A. Mean N X X i n i==1 Where, X = estimate of the mean.

i = individual sample, i.

N, n = total number of samples with positive indica tions. X i = value for sample i above the lower limit of detection.

B. Standard Deviation 2/1)1 (2)(1úú

ú

úû

é--==N X i X n i s Where, X = mean for the values of X s = standard deviation for the sample population.

3 - 30 3.7.2 ESTIMATION OF THE MEAN & 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 radio

-nuclide 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.

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

A. Mean N X X i n i==1 W here, X = estimate of the mean.

i = individua l sample, i.

N,n = total number of samples with positive indications.

X i = value for sample i above the lower limit of detection.

B. Error of the Mean (Reference 18) 2/1 1)(2úúúúûé==n i ERROR MEAN ERROR N Where, ERROR MEAN

3 - 31 3.7.3 LOWER LIMIT OF DETECTION (LLD)

The LLD is the predetermined concentr ation or activity level used to establish a detection limit for the analyti cal 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 u sed to calculate the LLD is:

)(exp)()22.2 ()()(66.4 t Y V E S LLD b D-=l Where: LLD = the a priori lower limit of detection, as defined above (in picocuries per unit mass or volume);

s b = 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 applicabl e); l = the radioactive decay constant for the particular radionuclide; D t = 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 approxima tely 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 negati ve). Table 3.8

-1 lists the ODCM program required LLDs for specific media and radionuclides as specified by the NRC.

The LLDs actually achieved are routinely lower than those specified by the ODCM.

3 - 32 3.8 COMPLIANCE WITH REQUIRED LOWER LIMITS OF DETEC TION (LLD)

ODCM, Part 1, Table 5.1

-3 specify the detection capabilities for environmental sample analysis (see Report Table 3.8

-1). ODCM, Part 1, Section 6.1 require that a discussion of all analyses for which the required LLDs specified were not routin ely achieved be included in the Annual Radiological Environmental Operating Report. Section 3.8 is provided pursuant to this requirement.

3.8.1 All sample analyses performed in 2005 , as required by the ODCM, achieved the Lower Limit of Detection (LLD) as specified by ODCM, Part 1, Table 5.1

-3. See report Table 3.8-1 for required LLD values.

3 - 33 TABLE 3.8-1 REQUIRED DETECTION CAPABILITIES FOR ENVIRONMENTAL SAMPLE ANALYSIS LOWER LIMIT OF DETECTION (LLD)

Analysis Water (pCi/l) Airborne Particulate or Gas es (pCi/m 3) Fish (pCi/kg, wet) Milk (pCi/l) Food Products (pCi/kg, wet) Sediment (pCi/kg, dry) Gross Beta 4 0.01 H-3 3000 (a) Mn-54 15 130 Fe-59 30 260 Co-58, Co-60 15 130 Zn-65 30 260 Zr-95, Nb-95 15 I-131 15 (a) 0.07 1 60 Cs-134 15 0.05 130 15 60 150 Cs-137 18 0.06 150 18 80 180 Ba/La-140 15 15 (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. Therefore an LLD value of 3000 pCi/liter is used for H

-3 and an LLD value of 15 pCi/liter is used for I

-131.

3 - 34 3.9 REGULATORY LIMITS Two federal agencies, the Nuclear Regulatory Commission and Environmental Protection Agency, have responsibility for re gulations promulgated for protecting the public from radiation and radioactivity beyond the site boundary.

3.9.1 The Nuclear Regulatory Commission (NRC):

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

• less than or equal to 100 mrem per year to the total body.

In addition to this dose limit, the NRC has established design objectives for nuclear plant licensees.

Conformance to these guidelines ensures that nuclear power reactor effluents are maintained as far below the legal limits as is reasonably achievable.

The NRC, in 10CFR 50, Appendix I, establishes design objectives for the dose to a

member of the general public from radioactive material in liquid effluents released to unrestricted areas to be limited to:

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

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

The air dose due to release of noble g ases in gaseous effluents is restricted to:

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

• 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 8 days in gaseous effluents is limited to:

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

3 - 35 The NRC, in 10CFR72.104(a)

, establishes criteria for radioactive materials in effluents and direct radiation from a n Independent Spent Fuel Storage Installation (ISFSI). During normal operations and anticipated occurrences, the annual dose equivalent

to any real individual who is located beyond the controlled area must not exceed:

• 25 mrem per year to the total body;

• 75 mrem per year to the thyroid and

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

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

2. Direct radiation from ISFSI.

3. Any other radiation from fuel cy cle operation in the region.

3.9.2 Environmental

Protection Agency (EPA).

The EPA, in 40CFR190.10 Subpart B, sets forth the environmental standards for the uranium fuel cycle. During normal operation, the annual dose to any member

of the public from th e entire uranium fuel cycle shall be limited to:

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

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

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

5 - 1 5.0 DATA EVALUATION AND DISCUSSION A. Introduction Each year the results of the Annual Radiological Environmental Monitoring Program (REMP) are evaluated considering plant operations at the site, the natural processes in the

environment and the archive o f 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, pop ulation dose estimates, risk estimates to the general population based on significance of environmental concentrations, effectiveness of plant effluent controls and specific research areas. The report not only presents the data collected during

the 2005 s ample 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 radion uclide in terms of potential increased dose to man, in relation to natural background, is necessary to determine the true significance of any detection.

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

Radioactiv ity 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 curi e 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), one millionth (0.000001) of a curie, and the picocurie (pCi), 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.

5 - 2 C. Dose/Dose to Man The dose or dose equival ent, 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 ca n 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 mu ltiplied by the absorbed dose, the result is the dose equivalent, which is an estimate of the possible biological damage resulting from exposure to any type of ionizing radiation.

The dose equivalent is measured in rem (roentgen equivalent man). In terms of environmental radiation, the rem is a large unit. Therefore, a smaller unit, the millirem (mrem) is often used. One millirem 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 There are three separate groups of radionuclide that were measured in the environment in the media analyzed for the 2005 sampling program.

The first of these groups consists of those radionuclide s 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 part icles from space called cosmic radiation, naturally

-occurring radioactive isotopes in the human body like potassium

-40, medical procedures, man-made phosphate fertilizers (phosphates and uranium are often found together in nature), and household items like televisions. In the United States, a person's average annual exposure from background radiation is 360 mrem, as illustrated on the following Background Radiation Chart.

5 - 3 Background Radiation Radiation Exposure in the U.S.(Percent of Total Effective Dose)

NCRP 93, 1987

< A number of radionuclid es are present in the environment due to sources such as cosmic radiation and fallout from nuclear weapons testing. These radionuclides 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 , present as a result of the interaction of cosmic radiation with the upper atmosphere,

• Beryllium

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

• Pota ssium -40 and radium

-226 , naturally occurring radionuclides found in the human body and throughout the environment, and

• Fallout radionuclides from nuclear weapons testing, including cesium

-137, and strontium

-90. Beryllium-7 and potassium

-4 0 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 natural

background radiatio n 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.

5 - 4 The second group of radionuclides that were detected are a result of the detonation of thermonuclear devices in the earth's atmosphere. Atmospheric nuclear testing during the early 1950s produced a measurable inventory of radionuclides presently found in the lower

atmosphere as well as in ecological systems. In 1963 an At mospheric Test Ban Treaty was signed. Since the treaty, the global inventory of man

-made radioactivity in the environment has been greatly reduced through the decay of short lived radionuclides and the removal of radionuclides from the food chain by such natural processes as weathering and sedimentation. This process is referred to in this report as ecological cycling. Since 1963, several atmospheric weapons tests have been conducted by the People's Republic of China. In each case, the usual radionuclid es 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 t he 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. The highest weapons testing concentration s were noted in samples collected for the 1981 REMP. Cs

-137 was the major byproduct of this testing and is still occasionally detected in a few select number of environmental media.

The third group of radionuclides that may be detected in the environment are those that 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 found in the Chernoby l fallout. This commonality makes a determination of the source of these radionuclides that may be detected in environmental samples difficult to determine. During 2005 , Cs-137 was the only potential plant

-related radionuclide detected in the REMP sampl es. A number of factors must be considered in performing radiological sample data evaluation

and interpretation. The evaluation is made using several approaches including trend

analysis and dose to man. An attempt has been made not only to report the da ta collected during 2005 , but also to assess the significance of the radionuclides detected in the environment as compared to natural and other man

-made radiation sources. It is important to note that detected concentrations of radionuclides in the local environment as a result of man's technology are very small and are of no or little significance from an environmental or dose to man perspective.

The 1987 per capita average dose was determined to be 360 mrem per year from all

sources, as noted in NCRP R eport No. 93 (Reference 1 3). This average dose includes such exposure sources as natural radiation, occupational exposure, weapons testing, consumer products and nuclear medicine. The 1987 per capita dose rate due to natural sources was 295 mrem per yea

r. The per capita radiation dose from nuclear power production nationwide is less than one mrem per year.

5 - 5 The natural background gamma radiation in the environs of the Nine Mile Point site, resulting from 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 Th

-232). A dose of 60 mrem per year, as a background dose, is significantly greater than any possible doses as a result of routine operations at the site during 2005. 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 detections with a dose to man estimate where appropriate, and an analysis of possible long term and short term trends.

During routine implementation of the REMP, additional or optional environmental

pathway media are sampled and ana lyzed. These samples are obtained to:

• Expand the area covered by the program beyond that required by the ODCM.

• Provide more comprehensive monitoring than is currently required,

• Monitor the secondary dose to main pathways, and

• Maintain the analytical d ata 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 t he 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 pr ovided for each required sample medium analyzed during the 2005 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 inc ludes 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 s ignificantly since 1969 due to technological advances in laboratory procedures and analytical equipment.

5 - 6 5.1 AQUATIC PROGRAM The aquatic program consists of samples collected from three environmental pathways. These pathways are:

• Shoreline Sediment

• Fish

• Surface Waters Section 6.0, Tables 6

-1 through 6

-4 present the analytical results for the aquatic samples collected for th e 2005 sampling period.

5.1.1 SHORELINE

SEDIMENT RESULTS A. Results Summary Shoreline sediment samples were obtained in Ap ril and October of 2005 at one offsite control location (Lang's Beach located near Oswego Harbor) and at one indicator location (Sunset Bay) which is an area east of the site considered to have recreational value.

A total of four sediment samples were co llected for the 2005 sample program, two indicator and two control. Cs

-137 was detected in two of the samples collected from the Sunset Bay indicator location in 2005 , measuring 0.090 and 0.063 pCi/g (dry). These results continue to show a downward t rend over the last 10 years. Cs

-137 was not detected in samples collected from the control location during 2005; however, Cs

-137 has been detected in past control samples. Cs

-137 was detected in control samples collected in 1993 at an average concentrat ion of 0.027 pCi/g.

The general lack of Cs

-137 at the control location is attributed to the differences in the sediment types between the two sample locations (See Data Evaluation and Discussion).

The source of the Cs

-137 detected in the indicator s horeline sediment is considered to be the result of fallout from atmospheric nuclear weapons testing and not from operations at the site. The mean concentration of Cs

-137 measured in the 2005 indicator sample is consistent with measured concentrations s ince shoreline sediment sampling began in 1985.

Historical mean concentrations measured at the indicator location ranged from a maximum of 0.33 pCi/g in 1993 to a minimum of 0.04 pCi/g (dry) in 2004. The results for the 2005 control location were less t han the detection limit. No other plant

-related radionuclides were detected in the 2005 shoreline sediment samples.

5 - 7 The calculated potential whole body and skin doses which may result from the measured Cs-137 concentrations are extremely small and are i nsignificant when compared to natural background doses.

The following is a graph of the average Cs

-137 concentration in shoreline sediment samples over the previous 12 years. This graph illustrates a general downward trend in the Cs-137 concentrations si nce 1993. Shoreline Sediment Cs-137 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 pCi/gram (dry)

CONTROL INDICATOR Control< LLD Value 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 2005. The results of these sample collections are presented in Section 6.0, Table 6

-1, "Concentrations of Gamma Emitters in Shoreline Sediment Samples

- 2005". Cesium-137 (Cs-137) and Potassium

-40 (K-40) were the primary radionuclides detected in the sediment samples.

Cs-137 was detected in the indicator sample s collected in April and October for the 2005 program. The measured concentration for t hese samples were 0.090 and 0.063 pCi/g (dry).

The presence of Cs

-137 in certain environmental sample media such as soil, shoreline sediment and fish is historically common. Cs

-137 is a fission product that is produced in nuclear power reactors and duri ng atmospheric weapons testing. In addition to the Cs

-137 found in the environment as a result of past weapons testing, a significant inventory of Cs

-137 was also introduced globally as a result of the Chernobyl accident in 1986. Because Cs-137 is found in environmental samples as a result of weapons testing and Chernobyl, it 5 - 8 is difficult to accurately determine the source of Cs

-137 measured in the sediment sample.

It is highly probable that the source of the cesium is from sources other than the operati on of plants at the Nine Mile Point Site. It is likely that any sediment sample containing Cs

-137 which was the result of plant operation would also contain other plant related isotopes such as Co

-60 and Cs-134. The absence of corroborating radionuclides would indicate that the source of Cs

-137 in sediment samples is from the existing background Cs

-137 which is attributed to weapons testing and the Chernobyl accident. This assessment is further substantiated by the fact that Cs

-137 was detected in the 19 93 sediment control sample.

Historically, Cs

-137 has been routinely measured in the control samples of other environmental media such as fish and soil.

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 fine sediment and/or sand which would be representative of the indicator location.

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

sampling. Recent soil samples from locations beyond any expected influen ce from the site have contained levels of Cs

-137 equal to or greater than the concentrations found in the 2005 shoreline sediment samples. The Cs

-137 is commonly found in soil samples and is attributed to weapons testing fallout. Shoreline samples conta ining soil or sediment are likely to contain Cs

-137. C. Dose Evaluation The radiological impact of Cs

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

regulatory guide values and the maximum 2005 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 measured Cs-137 concentration of 0.090 pCi/g (dry).

Using these conservative parameters, the potential dose to the maximum exposed

individual (teenager) would be 0.00030 mrem/year to the whole body and 0.00036 mrem/year to the skin. This calculated dose is very small and is insignificant when compared to the natural background annual exposure of approximately 60 mrem as measured by control TLDs in the vicinity of the site.

5 - 9 D. Data Trends The mean Cs

-137 concentration for the shoreline sediment indicator sample for 2005 was 0.08 pCi/g (dry).

This is consistent with mean concentration measured at the indicator location over the past ten years. The previous five years of data show a stable mean concentration values measured at the indicator location

s. Over the five year period, mean concentrations ranged from a high of 0.07 pCi/g (dry) in 2000 and 2001 to a low value of 0.04 pCi/g (dry) measured in 2004. Cesium-137 was not detected in the control location samples over this same five year period. The previous ten year data trend for indicator shoreline samples showed a overall downward trend in concentration measured at the indicator sample locations. Over the previous ten year period of 199 5 through 2004 , mean concentrations at the indicator location ranged from a maximum of 0.17 pCi/g (dry) in 199 6 and 1997 to a minimum of 0.04 pCi/g (dry) measured in 200 4. The mean indicator concentration measured in 2005 of 0.08 pCi/g (dry) continues 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

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

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

5 - 10 5.1.2 FISH SAMPLE RESULTS A. Results Summary A total of 20 fish samples were collected for the 2005 sample program. Speci es collected were: smallmouth bass, brown trout, walleye and Chinook salmon. The analytical results for the 2005 fish samples showed no detectable concentration of radionuclide that would be attributable to plant operations at the site or past at mospheric weapons testing. The absence of Cs

-137 in the 2005 fish samples is significant in the fact that it continues to validate the absence of Cs

-137 in fish samples observed in the previous two years

. With the exception of 2001, 2003, 2004 and 2005 , positive concentrations of Cs

-137 have been measured in fish samples collected in the previous 20 years at a combination of both the indicator and/or control locations. (Refer to Tables 7

-3 and 7-4). These low levels of Cs

-137 represented no significant dose to man or impact on the environment.

The 2005 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 2005 re sults are consistent with previous year's results in that they continue to support the general long

-term downward trend in fish Cs

-137 concentrations over the last 24 years. Cs

-137 was not detected in fish samples collected in 2000, 2001, 2003, 2004 and 2 005 from indicator locations. The period of 2000 through 2005 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 a nd JAFNPP samples served as indicator samples. All samples were analyzed for gamma emitters. Section 6.0, Table 6

-2 shows individual results for all the samples collected in 2005 in units of pCi/g (wet).

The spring fish collection was made up of 9 indi vidual samples representing three separate species. Walleye, smallmouth bass and brown trout were collected from all three locations.

The total fall fish collection was comprised of 11 individual samples representing four individual species.

Brown tro ut, Chinook salmon and walleye were collected from all three sampling locations.

Smallmouth bass were collected at the control and JAFNPP indicator locations.

Cs-137 was not detected in any of the fish species collected for the 2005 sample progr am 5 - 11 C. Dose Evaluation Fish represent the highest level in the aquatic food chain and have the potential to be a contributor to the dose to man from the operations at the site. The lack of detectable

concentrations of plant

-related radionuclides in the 2 005 fish samples demonstrates that there is no attributable dose to man from operations at the site through the aquatic pathway. Some Lake Ontario fish species may be considered an important food source due

to the local sport fishing industry. Therefore , these fish are an integral part of the human food chain.

D. Data Trends The Cs-137 data for fish samples over the previous five years (2000 through 2004) show that the number of positive detections has decreased over this period relative to historic al data. With the exception of 2002 there was no positive detection of Cs

-137 over the previous five year period at the indicator locations. There are no positive detections in 2001, 2003 or 2004 and only intermittent detections in the remaining years o f this period.

The general lack of positive detections was continued in the 2005 sample year.

The graph below illustrates the mean control and indicator Cs

-137 concentrations for 2005 and the previous ten years.

5 - 12 The ten year data trend shows a cons istent level of Cs

-137 measured in fish between 1994 and 2000. After 2000, the number of positive detections drops off as noted in the five year trend. The 1994 through 2004 results, as a group, are the lowest Cs

-137 concentrations measured over the exis tence of the sample program.

The general long

-term decreasing trend for Cs

-137, illustrated in the graph below, is most probably a result of the cesium becoming unavailable to the ecosystem due to ion exchange with soils and sediments and radiological dec ay. 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.

5 - 13 5.1.3 SURFACE WATER (LAKE)

A. Results Summary The ODCM requires that monthly surface water samples be taken from the respective inlet water supplies of the JAFNPP and NRG Energy's Oswego Steam Station. In conjunction with the required samples, three additional Lake Ontario surface water locations are sampled and analyzed. These additional locations are the Oswego City Water Intake, the NMP1

Intake and the NMP2 Intake. Gamma spectral analysis was performed on 24 monthly composite samples from the ODCM locations and on 36 monthly composite samples collected from the additional sample locations. The results of the gamma spectral analyses

showed that only naturally

-occu rring radionuclides were detected in the 60 samples from the five locations collected for the 2005 Sampling Program. The two naturally

-occurring radionuclide detected were K-40 and Ra-226 and were not related to plant operations.

Monthly composite samp les 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 wer e analyzed for tritium as part of the 2005 REMP program.

The results for the 2005 samples showed no positive detections of tritium. All results for 2005 were below the established measurement sensitivity and are reported as less than the lower limit of detection (<

LLD). There is no indication of a long

-term buildup of tritium concentrations in the surface waters adjacent to the site.

B. Data Evaluation and Discussion Gamma spectral analysis was performed on monthly composite samples from five Lake Ontario sampling locations.

No plant-related radionuclide s were detected in 2005 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 s amples that are a composite of the applicable monthly samples for a given location. Tritium samples analyzed for the 2005 sample program were analyzed to an instrument detection level of 500 pCi/l.

The tritium results for the JAFNPP inlet canal sampl es contained no positive detections. The 2005 results had LLD values that ranged from

<41 6 pCi/l to <498 pCi/

l. The ODCM Control location (Oswego Steam Station inlet canal) results showed no positive detections and the sample results had LLD values in t he range of

<413 pCi/l to <

471 pCi/l.

5 - 14 Tritium was not detected in any of the twelve optional Lake Ontario samples collected in the 2005 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.

No positive detections of tritium were identified in 2005. The following is a summary of LLD results for the 2005 sample program: Tritium Concentration pCi/liter Sample Location Minimum Maximum Mean (Annual) JAF Inlet (Indicator)*

<416 <498 <440 Oswego Steam Inlet (Control)*

<413 <471 <432 NMP #1 Inlet

<413 <471 <432 NMP #2 Inlet <413 <471 <432 Oswego City Water Supply

<413 <471 <432

• Sample location required by ODCM The above LLD values are far below the ODCM required LLD value of 3000 pCi/l.

Analytical results for surface water samples are found in Sectio n 6.0, Tables 6

-3 through 6-4. C. Dose Evaluation The radiological impact to members of the public from low levels of tritium in water is insignificant. This can be illustrated by calculating a dose to the whole body and maximum organ using the maxim um LLD value and Regulatory Guide 1.109 methodology. Based on a water ingestion rate of 510 liters/yr and the maximum 2005 LLD concentration of <4 98 pCi/l, the calculated dose would be less than 0.0 52 mrem to the child whole body and less than 0.0 52 mre m to the child liver (critical age group/

organ).

5 - 15 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 2005 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 2000 - 2004 ranged from <LLD pCi/l to 212 pCi/l for the co ntrol and 185 pCi/l to 297 pCi/l for the indicator location. By comparison, the mean 2005 tritium concentrations were

<432 pCi/l and <440 pCi/l for the control and indicator locations respectively. The previous five year data indicates no significant t rends 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, 1995 through 2004 , is representat ive of natural variations in environmental tritium concentrations with no significant levels of tritium measured. The 1999 mean control value of 337 pCi/l is the highest concentration 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 On tario over the past 20 years at both an indicator and control location. Prior to 1985, the Oswego City Water Supply results were used as control location data as this location closely approximates the Oswego Steam Station, the current control location.

T here is no existing preoperational data for comparison to recent data.

5 - 16 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 200 5 r eporting 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 2005 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 concentrati on for samples collected from the control location (R

-5) in 200 5 was 0.019 pCi/m 3. The mean gross beta concentration for the samples collected from the indicator locations (R

-1, R-2, R-3, and R-4) in 2005 was 0.01 9 pCi/m 3. The mean gross beta res ults for the indicator and the control stations were equivalent in 2005. 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 indic ator results are consistent with concentrations measured over the last fifteen years. This consistency demonstrates that the natural baseline gross beta activity has been reached. The man

-made radionuclide contribution to the natural background from atmo spheric weapons testing and Chernobyl can no longer be detected above the background concentrations of naturally occurring beta emitting radionuclides

.

5 - 17 B. Data Evaluation and Discussion The air monitoring system consists of fifteen sample locations, six onsite and nine offsite.

Each location is sampled weekly for particulate gross beta activity. A total of 780 samples were collected and analyzed as part of the 2005 program. Five of the nine offsite 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 offsite and onsite air sample locations are maintained from which weekly samples are collected. The optional offsite locations are designated as D-2, E, F and G. The optional onsite locations are designated as D

-1, G, H, I, J and K.

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.

Section 6.0, Tables 6

-5 and 6-6 present the weekly gross beta activity results for sample s collected from the offsite and onsite locations.

The average annual gross beta indicator concentrations for the ODCM indicator stations (R-1, R-2, R-3 and R-4) was 0.01 9 pCi/m 3. The offsite ODCM control station (R

-5) annual mean gross beta concentrat ion was also 0.019 pCi/m 3. The minimum, maximum and average gross beta results for sample locations required by the ODCM were as follows: Concentration pCi/m 3 Location Minimum Maximum Mean R-1 0.009 0.036 0.019 R-2 0.008 0.04 1 0.019 R-3 0.008 0.032 0.018 R-4 0.007 0.034 0.01 9 R-5 (control) 0.008 0.034 0.019 R1 - R4 Indicator Stations Min 0.007 Max 0.041 Mean 0.019 5 - 18 The mean weekly gross beta concentrations measured in 2005 are illustrated in the following graphs:

The concentrations of naturally

-occurring radionuclides in the lower levels of the atmosphere directly abo ve the land are affected by time

-related processes such as wind direction, precipitation, snow cover, soil temperature and soil moisture content.

5 - 19 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 contr ol value was 0.165 pCi/m

3. The 1981 samples were affected by fallout from a Chinese atmospheric nuclear test which was carried out in 1980. The mean gross beta concentration measured in 1977 to 2005 are illustrated in the

following graph:

Air Particulate Filter - Gross Beta 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 1969 1977 1981 1985 1989 1993 1997 2001 2005 pCi/m 3 INDICATOR CONTROL Chernobyl Accident The tren d 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. The change in concentrations over the period of

199 2 th rough 2005 is very small

. This is illustrated by the following graph.

-5) has remained steady with a narrow range of 0.01 3 pCi/m 3 to 0.019 pCi/

m 3. The mean annual concentrations for the indicator stations for this same time period were similar to the control and ranged from a minimum of 0.010 pCi/m 3 in 1997 to a maximum mean of 0.018 pCi/m 3 in 2005. Historical data of air particulate gross beta activity are presented in Section 7.0, Tables 7

-9 and 7-10. 5.2.2 MONTHLY PARTICULATE COMPOSITES (GAMMA EMITTERS)

A. Results Summary Fifteen air monitoring stations are maintained ar ound the Nine Mile Point Site. Five of the 15 air monitoring stations are required by the ODCM and are located offsite near the site boundary and offsite as a control location. Ten additional air sampling stations are also maintained as part of the sampl ing 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 pro vide 780 individual air particulate samples which are assembled by location into 180 monthly composite samples. The monthly composites are analyzed using gamma spectroscopy

. No plant-related gamma emitting radionuclides were detected in any of the air p articulate filter samples collected during 200 5. The gamma analysis results for the monthly composite samples routinely showed positive

detections of Be

-7, K-40, and Ra

-226. Each of these radionuclides is naturally occurring.

5 - 21 B. Data Evaluation Discus sion A total of fifteen air sampling stations are in continuous operation and located both onsite and in the offsite 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 month is assembled by location to form monthly compos ite samples. The monthly 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 onsite locations and four offsite locations. The analytical results for the 180 air particulate filter composites in 2005 showed no detectable activity of plant related radionuclides.

The results of the monthly composite samples are presented in Section 6.0, Table 6

-9. C. Dose Evaluation The calculated dose as a result of plant effluents is not evaluated due to the fact that no plant related radionuclides were detected in 2005. The monthly air particulate sampling program demonstrated no offsite dose to man from thi s pathway as a result of operations of the plants located at the Nine Mile Point Site.

D. Data Trends No plant related radionuclides were detected during 2005 at the off site air monitoring locations.

The ten year database of air particulate composi te 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 cont rol locations, with the exception of 1980 when Co

-60 was not detected at the control location. The presence of Co

-60 in the air samples collected during these years was the result of atmospheric weapons testing. Co

-60 was again detected in an offsite 200 0 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 C o-60 in the environment surrounding the N ine Mile Point site.

5 - 22 Historical data shows that 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 was again detected in 1986 as a result of the Chernobyl accid ent. Since 1986 there have been no detections of Cs

-137 in the environment surrounding the N ine Mile Point site. After 1986, no plant related or fallout radionuclides were detected in any of the offsite air particulate composite samples with the exc eption of the isolated detection of Co

-60 in 2000 in a single sample. A review of the past five year's data for air particulate filter composites indicates no plant related radiological impact on the environment from operations at the FitzPatrick plant. 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.

Historical data for air particulate results are presented in Section 7.0, Tables 7

-13 and 7-14. 5.2.3 AIRBORNE RADIOIODINE (I

-131) A. Results Summary Iodine-131 (I-131) was not detected in any of the 780 samples analyzed for the 2005 program. No radioiodine has been measured offsite at the constant air monitoring stations since 1987. B. Data Evaluation and Discussion Airborne radioiodine is monitored at the fifteen air sampling stations also used to collect air particulate samples. There are nine offsite locations, five of which are re quired by the ODCM. The offsite 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 onsite. D

-2, E, F and G are the optional stations located offsite.

Samples are collected using activated charcoal cartridges. They are analyzed weekly for I

-131. I-131 was no t detected in any of the 2005 samples collected. The analytical data for radioiodine are presented in Section 6.0, Tables 6

-7 and 6-8.

5 - 23 C. Dose Evaluation The calculated dose as a result of I

-131 was not evaluated due to the fact I

-131 was not detecte d during 2005. The I-131 sampling program demonstrated no off site dose to man from this pathway as a result of operation of the plants located at Nine Mile Point.

D. Data Trends No radioiodine has been detected in samples collected from the air sam pling locations required by the ODCM since 1987.

There has been no positive detection of I

-131 in air samples collected over the last ten years. This demonstrates that there is no measurable environmental impact or positive trend for iodine buildup due t o plant operations during the period from 1996 through 2005. I-131 has previously been detected in samples collected during the last twenty year period in 1986 and 1987. The 1986 detection of I

-131 was the result of the Chernobyl accident and the 1987 detection was the result of plant operations.

Iodine-131 has been detected in the past at control locations. Control samples collected during 1976 had a mean I

-131 concentration of 0.60 pCi/m

3. During 1977 this mean decreased to 0.32 pCi/m 3 , and further decreased by a factor of ten to 0.03 pCi/m 3 in 1978.

I-131 was not detected in samples collected from the control location during 1979

- 1981 and 1983 to 1985. I

-131 was detected once at the control location during 1982 at a concentration o f 0.039 pCi/m

3. Iodine-131 has been detected in samples collected from the on

-site indicator locations during 1980 to 1983 and 1986 to 1987. The mean concentrations ranged from 0.013 pCi/m 3 in 1980 to a maximum of 0.119 pCi/m 3 in 1986. The maximum mean indicator I

-131 concentration of 0.119 pCi/m 3 was the result of the Chernobyl accident. I

-131 was 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 I

-131 in samples collected in 1986 was the direct result of the Chernobyl Nuclear accident.

Historical data for I

-131 are presented in Section 7.0, Tables 7

-11 and 7-12.

5 - 24 5.2.4 DIRECT RADIATION THERM OLUMINESCENT DOSIMETERS (TLD)

A. Results Summary Thermoluminescent dosimeters (TLDs) are used to measure direct radiation (gamma dose) in the environment. As part of the 2005 environmental monitoring program, TLDs were placed at a total of 72 different environmental TLD locations (3 3 required by the ODCM and 39 optional locations). These TLDs were placed, collected and read each quarter of 2005. As a result of placing two TLDs at each location, the results presented in this report are the avera ge of two TLD readings obtained for a given location.

The 72 TLDs were placed in the following five geographical locations around the site

boundary:

• Onsite (areas within the site boundary),

• Site Boundary (area of the site boundary in each of the 16 meteor ological sectors),

• Offsite Sector (area four to five miles from the site in each of the eight land based meteorological sectors),

• Special Interest (areas of high population density and use), and

• Control (areas beyond significant influence of the site).

A ll geographical locations are required by the ODCM with the exception of the Onsite 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

.1.5, TLD (Direct Radiation) of this report.

A summary of the 2005 dose rates for each of the five geographical locations is as follows: Dose in mrem per standard month Geographic Category Min Max Mean Onsite (Optional) 3.4 14.1 5.4 Site Boundary (I nner Ring) *

(1) 3.4 4.8 4.2 Offsite Sectors (Outer Ring)

• 3.2 4.7 4.0 Special Interest *

(2) 3.4 5.1 4.1 Control *

(3) 3.4 5.1 4.3

• Geographical locations required by the ODCM 1 Only includes TLD results that are not affected by radwas te direct shine (TLD #s. 78, 79, 80, 81, 82, 83, 84, 7, 18) 2 Only includes TLD results required by the ODCM (TLD #s. 15, 56, 58, 96, 97, 98) 3 I ncludes TLD results from locations #8, 14 & 49.

5 - 25 Comparison of annual m ean 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 wit h the dose rates measured at the site boundary and control locations. The results for the Site Boundary, Offsite Sectors and Special Interest (Offsite) were well within expected normal variation when compared to the Control TLD results.

The results fo r the 2005 environmental TLD monitoring program indicate that there was no significant increase in dose rates as a result of operations at the site. The Hydrogen Water Chemistry system and the Independent Spent Fuel Storage Installation (ISFSI) in use at the FitzPatrick plant 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 locatio ns during 2005 , 3 3 of which are required by the ODCM. These locations are grouped into five geographical location categories for evaluation of results. The five categories include: Onsite, Site Boundary, Offsite Sector, Special Interest and Control

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

JA FNPP facilities.

Onsite TLDs are optional and are subdivided into three categories for which direct radiation results are evaluated. The 2005 direct radiation results for Onsite TLD locations were as follows:

1. Results for TLDs located near the NMP1, NMP2 and JAFNPP generating facilities and at previous or existing on

-site air monitoring stations ranged from 3.4 to 14.1 mrem per standard month.

2. Results for TLDs located near the north shoreline of NMP1, NMP2 and Fitzpatrick facilities in cl ose proximity to the Radwaste and Unit 1 Reactor Building ranged from 3.4 to 37.3 mrem per standard month. 3. Results for TLDs located onsite near the Energy Information Center and its associated shoreline ranged from 4.1 to 5.6 mrem per standard mont h.

5 - 26 Site Boundary TLD results ranged from 3.4 to 9.2 mrem per standard month in 2005. 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 r equired by the ODCM was 9.2 mrem per standard month. This TLD, (TLD 85) represents the site boundary maximum dose and is located in the WNW sector along the lake shore in close proximity to the NMP1 plant. The TLD locations along the lakeshore close to the plants (TLD #s 75, 76, 77, 85, 86 and 87) are influenced by radwaste buildings and radwaste shipping activities. These locations and are not accessible to members of the public and the TLD

results for these areas are not representative of dose rates m easured at the remaining site boundary locations. The remaining Site Boundary TLD locations, which are located away from the plant ranged from 3.4 to 4.8 mrem per standard month resulting in an average dose rate of 4.2 mrem per standard month.

Offsite Sector TLDs, required by the ODCM, located 4 to 5 miles from the site in each of the 8 land based meteorological sectors ranged from 3.2 to 4.7 mrem per standard month with an average dose rate of 4.0 mrem per standard month. Special Interest TLDs from all locations ranged from 3.4 to 5.1 mrem per standard month with a 2005 annual average dose rate of 4.1 mrem per standard month. The Control TLD group required by the ODCM utilizes locations positioned well beyond

the site.

2005 Control TLD results ranged from 3.4 to 5.1 mrem per standard month with an annual average dose rate of 4.3 mrem per standard month. These results include both the ODCM required control TLDs and the additional control TLDs. TLD analysis results are presented in Sect ion 6.0, Table 6

-10. C. Dose evaluation 2005 annual mean dose rates for each geographic location required by the ODCM are as follows: Site Boundary:

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

Offsite Sectors:

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

Special Interest:

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

Control: 4.3 mrem per standard month (TLD #s 8, 14, 49) 5 - 27 The measured mean dose rate in the proximity o f the closest resident was 4.2 mrem per standard month (TLD #s: 108, 109) which is consistent with the control measurements of 4.3 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 offsite environment.

D. Data Trends A comparison of historical TLD results can be made using the different geographical categories of measurement locations. These include Site Boundary TLDs located in each of the 16 meteorological sectors, TLDs located offsite in each land based sector at a

d istance of 4 to 5 miles from the site, TLDs located at special interest areas and TLDs located at control locations. Site Boundary, Offsite Sector and Special Interest TLD locations became effective in 1985; therefore, trends for these results can only be evaluated from 1985 to the present.

The following graph illustrates TLD results for the Control, Site Boundary, Offsite Sectors

and Special Interest groups from 1992 through 2005

TLD Data - Yearly Mean 0 1 2 3 4 5 6 1994 1996 1998 2000 2002 2004 mRem/Standard Month Control Site Boundary Offsite Specials 5 - 28 TLDs located at the site boundary averaged 4.2 mrem per standard m onth during 2005 (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 4.4 mrem per standard month. Offsite Sector TL Ds averaged 4.0 mrem per standard month during 2005. This result is also consistent with the previous five year average of 4.3 mrem per standard month for offsite sectors.

Special Interest TLD locations averaged 3.

9 mrem per standard month during 2005 which is consistent with the previous five year average of 4.4 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. 2005 control results from all Control TLDs averaged 4.3 mrem per standard month, consistent with the previous five year average of 4.4 mrem per standard month. The 2005 TLD program results, when compared to the previous twenty years, showed no signi ficant trends relative to increased dose rates in the environment.

5.2.5 MILK A. Results Summary A total of 72 milk samples were collected dur ing the 2005 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 (I-131). I-131, a possible plant related radionuclide, is measured to evaluate the cow/milk dose pathway to man. I

-131 was not detected in any of the 72 milk samples collected in 2005 from the four milk sample locations. Gamma spectral analyses of the milk samples showed only naturally occurring

radionucli des, such as K

-40, were detected in milk samples collected during 200

5. K-40 was detected in all indicator and control samples.

K-40 is a naturally occurring radionuclide and is found in many environmental sample media.

The 2005 results demonstrat e that routine operations of the Nine Mile Point Site resulted in no measurable contribution to the "dose to the public" from the cow/milk pathway.

5 - 29 B. Sampling Overview Milk samples were collected from three indicator locations and one control location.

The ODCM requires that three sample locations be within five miles of the site. Based on the milk animal census, there were no adequate milk sample locations within five miles of the

site in 2005. Samples were collected from four farms located beyond the five-mile requirement to ensure the continued monitoring of this important pathway. The three indicator locations ranged from 6.

3 to 8.7 miles from the site. The control samples were collected from a farm located 16.0 miles from the site and in a low frequency wind sector (upwind). The geographic location of each sample location is listed below:

Location No.

Direction From Site Distance (Miles) 76 E SE 6.3 55 E 8.7 4 ESE 7.6 77 (Control)

S 16.0 Samples were collected from Indicator locations #4, #

55 , # 76 and Control location #77 from April through December, during the first and second half of each month. Samples were not required to be collected during January through March of 2004 as a result of I

-131 not having been d etected in samples collected during November and December of 2004 , as stipulated in the ODCM.

C. Data Evaluation and Discussion Each milk sample is analyzed for gamma emitters using gamma spectral analysis. The I

-131 analysis is performed using resin e xtraction followed by spectral analysis for each sample. I

-131 and gamma analysis results for milk samples collected during 2005 are provided in Section 6.0, Table 6

-11. Iodine-131 was not detected in any indicator or control milk samples analyzed durin g 2005. All I-131 milk results were reported as Lower Limits of Detection (LLD). The LLD results for all samples ranged from

< 0.34 to < 0.85 pCi/

liter. No plant

-related radionuclides were detected in any milk sample collected in 2005. 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. The K

-40 concentration for all milk samples analyzed range d from 1310 to 1930 pCi/liter. Cs-137 was not detected in any indicator or control milk sample collected in 2005.

5 - 30 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 th e 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 (inhalatio n, 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 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.

I-131 was measured in two milk samples collected in 1997 from a single 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 concentration of 13.6 pCi/liter. The 1986 activity was a result of the Chernobyl accident.

The comparison of 2005 data to historical results over the operating life of the plants shows that Cs

-137 and I-131 levels have decreased significantly since 1983. Historical data of milk sample results for Cs

-137 and I-131 are presented in Section 7.0, Tables 7-17 and 7-18.

5.2.6 FOOD PRODUCTS (V EGETATION)

A. Results Summary There were no plant

-related radionuclides detected in the 16 food product samples collected and analyzed for the 2005 program. Detectable levels of naturally occurring K

-40 were measured in all control and indicator sample s collected for the 2005 program. Be-7 a naturally

-occurring radionuclide, w as also detected intermittently in samples collected in 2005. These results are consistent with the levels measured in 2004 and previous years

. The results of the 2005 sampli ng program demonstrate that there is no measurable impact on the dose to the public from the garden pathway as a result of plant operations

.

5 - 31 B. Data Analysis and Discussion Food product samples were collected from four 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 2005 included one variety considered to be an edible broadleaf vegetabl

e. Collards, an edible broadleaf vegetable, was collected from one indicator location. Collards was not available from the control location. 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 squash leaves, bean leaves, rhubarb, grape leaves, pumpkin leaves, squash leaves, and cucumber leaves were collected for the 2005 program. The leaves of these plants were sampled as representative of broadleaf vegetati on which is a measurement of radionuclide deposition. In addition to the broadleaf vegetation, tomato samples were collected from three locations. Samples were collected during the late summer/fall harvest season. Each sample was analyzed for gamma emi tters using gamma spectroscopy.

The analysis of food product samples collected during 2005 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 ga rden food products grown in areas close to the site. Naturally occurring Be

-7 and K-40 were detected in food product samples. The concentration of Be

-7 in vegetation samples ranged from 0.28 to 1.

02 pCi/g (wet). The concentration of K-40 in indicator and control samples ranged from 1.95 to 4.16 pCi/g (wet). The results for naturally

-occurring radionuclides are consistent with the data of prior years.

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

-12. C. Dose 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 food product sampling program demonstrated no measurable offsite dose to man from this pathway a s a result of operations of the plants located at Nine Mile Point.

5 - 32 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 p roducts 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 0.00 7 pCi/g (wet).

Historically, Cs

-137 had been detected in ten separate years since 1976 ra nging from a maximum mean concentration of 0.047 pCi/g (wet) in 1985 to a minimum of 0.008 pCi/g (wet) in 1999. The trend for Cs

-137 is a general reduction in concentration to non detectable levels in samples collected during the 2000 through 2005 sample programs. Historical data of food product results are presented in Section 7.0, Tables 7

-19 and 7-20. 5.2.7 LAND USE CENSUS RESULTS A. Results Summary The ODCM requires that an annual land use census be performed to identify potential new locatio ns for milk sampling and for calculating the dose to man from plant effluents. In 2005 , a milk animal census, a nearest resident census and a garden survey were performed. The results of the closest residence census conducted in 2005 required no change t o the James A. FitzPatrick Nuclear Power Plant Dose Calculation Manual (ODCM)

. 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 Appendix H of the ODCM and identified in the census as active for 2005. See Table 3.3

-1 for 2005 sampling locations. B. Data Evaluation and Discussion A land use census is conducted each year to determine the utilizatio n 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.

5 - 33 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 n ew 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 507 cows and 7 goats based on the 2005 land use census. The number of cows has increased by 7 a nd the number of goats has decreased by 3 when compared to the 2004 census. The goats identified during the census were not milking goats. The results of the milk animal census are found in Section 6.0, Table 6

-13. The second type of census conducted i s 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. No changes were identified i n the 2005 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. 5.2.8 DIRECT RADIATION, THERMOLUMINESCENT DOSIMETERS (TLD)

Independent Spent Fuel Stora ge Installation (ISFSI)

A. Results Summary Thermoluminescent Dosimeters (TLDs) are used top measure direct radiation (gamma dose) in the localized environment of the ISFSI pad. Eighteen TLD locations are in place

around the perimeter of the ISFSI pad.

TLDs were placed at these locations prior to loading the first storage casks for baseline dose rate determination in the general area of the pad. On April 25, 2002, the ISFSI facility was placed in service with the installation of the first

storage cask o n the pad. Two subsequent storage casks were moved to the storage facility on May 8, 2002 and M ay 21, 2002. A second series of six storage casks were added to the storage facility star t in g on September 6, 2005. The sixth and last cask in this series was placed in the storage facility on November 12, 2005 bringing the total number of casks in 5 - 34 storage to nine. Dose rates measured around the p eri meter of the storage facility during the first 3 quarters of 2005 were consist e nt with tho se measured in the pre vious year. The mean quarterly dose rates increased by a factor of 1.3 in the fourth quarter over a the mean of the previous three quarters. The maximaum dose rate measured in the first 3 quarters of 2005 was 29.7 mrem per standard month. The maximum dose rate in the fourth quarter of 2005 was 33.2 mrem per standard month total or 19.7 mrem per standard mo n th above the applicable baseline dose rate. The change in dose rate is the result of the six casks that were loaded on the pad starting in September of 2005. The nine casks are located on the northern end of the pad are in close proximity to the north ISFSI perimeter fence. In addition, the radiation exposure from hydrogen water chemistry also contribute to the higher dose rates measured at the north fe nceline of the ISFSI storage facility.

The increase in dose rate is limited to the general area of the storage facility. The implementation and loading of the ISFSI project has resulted in no increase in dose at the site boundary or to the public. The an alysis of offsite doses from direct radiation measurements, presented in Section 5.2.4 of this report, concludes that there is no significant difference in annual dose to the public at or beyond the site boundary. The

measured annual dose rate at the near est residence to the site was consistent with the dose rates measured at the site boundary and the offsite control locations. The results for the Site Boundary, Offsite Sectors, and Special Interest (offsite) were well within expected normal variation whe n compared to the Control TLD results. The results for the 2005 environmental TLD monitoring program indicate that there is no significant increase in dose rates as a result of operations at the site. The use of hydrogen injection and the

implementation of the Independent Spent Fuel Storate Installation (ISFSI) at the FitzPatrick plant did not measurably increase the ambient radiation exposure rate at or beyond the site boundary. The lack of a dose rate increase at or beyond the s i te boundary is consiste nt with design calculations performed to evaluate compliance with 10 CFR72.104(a).

The measured results of the 2005 TLD monitoring program demonstrate compliance with

the offsite dose limits to members of the public specified in 40CFR190 and

10CFR72.104(a

). B. Program Design An array of eight TLD locations was established around the perimeter of the ISFSI pad 18

months prior to facility usage. Six months prior to the facility becoming operational, an

additional 10 TLD locations were established at areas of interest on the facility perimeter.

These preoperational TLDs were used for baseline dose rate determination. The TLDs are placed, collected and read each quarter. Two dosimeters are placed at each location and 5 - 35 the average of the two dosimeters is r eported. The quarterly results are compared to baseline data to assess the contribution to ambient dose rates in the vicinity of the storage facility from casks as they are placed on the storage pad.

C. Dose Evaluation The maximum dose rate of 19.7 mrem per standard month above the baseline dose rate was measured during the fourth quarter at the north perimeter fence. The lowest measured dose rate in the fourth quarter of 2005 was 5.6 mrem per standard month above th e baseline dose rate and was measured at the southern perimeter fence due to the larger distance between the casks and the perimeter fence.

The maximum dose at the southern perimeter fence was slightly higher at 8.6 mrem per standard month.

The western perimeter fence had a maximum measured dose rate of 12.2 mrem above the baseline. The maximum measured dose rate on the eastern perimeter fence was 10.5 mrem per standard month above the baseline.

An evaluation of Site Boundary TLDs and Control TLDs results for 2005 shows that there

is no increase in dose rate at or beyond the site boundary. A detailed discussion of this evaluation is found in Section 5.2.4. The Environmental TLD results for this period show no significant difference in control and site boundary dose rates for 2005.

5.3 CONCLUSION

The Radiological Environmental Monitoring Program (REMP) is an ongoing program implemented to measure and docum ent the radiological impact of the James A. FitzPatrick operations on the local environment. The program is designed to detect and evaluate small changes in the radiological environment surrounding the site. Environmental media representing

food sources consumed at the higher levels of the food chain, such as fish, food products and milk, are part of a comprehensive sampling program. Results of all samples are reviewed closely to determine any possible impact to the environment or to man. In addition, p rogram 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 do se 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 (10CFR20).

The Environmental Protection Agency (EPA) limits the annual whole body dose to 25 mrem/yr, which is specified in Section 10, Part 190, Title 40, of the Code of Federal Regulations (40CFR190). 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 2005 Ra diological Environmental Surveillance Program 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 characte ristics were measured or observed in the local environment. The Environmental Monitoring Program continues to demonstrate that the effluents from the site to the environment contribute no significant or even measurable radiation exposures to the general p ublic 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 and the onsite Independent Spent Fuel Storage Installation (ISFSI) program. Environmental radiation levels measured at the nearest residence are at the background level based on control station TLD results. The only measurable radiological impac t on the environment continues to be the result of atmospheric weapons testing conducted in the early 1980s and the 1986 accident at the Chernobyl Nuclear Power Plant. Both of these source terms have contributed to a measurable inventory of Cs

-137 in the environment. The results for the 2005 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 mo re sensitive to the measurable impact of plant operations on the environment as time goes on.

5 - 37 The environmental monitoring program detected one potential plant

-related radionuclide in the sample media collected during 2005. Cs-137 was detected in one s horeline sediment sample. The source of the Cs

-137 measured in this sample is considered to be fallout from past atmospheric nuclear weapons testing. The measured concentration of Cs

-137 in the sample was small and consistent with historical results fo r shoreline sediment. The impact of these Cs

-137 concentrations are minimal in terms of dose to man. Dose from man

-made sources in the environment is very small when compared to the dose originating from naturally

-occurring sources of radioactivity.

R adiation 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 comp arison to the dose contribution from natural background levels and sources other than the plants. The whole body dose in Oswego County due to natural sources is approximately 50

- 60 mrem per individual per year as demonstrated by control environmental TL Ds. The fraction of the annual dose to man, attributable to site operation, remains insignificant.

Based upon the overall results of the 2005 Radiological Environmental Monitoring Program, it can be concluded that the levels and variation of radioactiv ity in the environment samples were consistent with background levels that would be expected for the lakeshore environment of the site.

6 - 1 6.0 REPORT PERIOD ANALYTICAL RESULTS TABLES

6.1 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 posi tive values and LLD values where applicable.

6.2 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 "rea l" signal (see Section 3.7.3 for detailed explanation).

6.3 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 analyti cal results for that radionuclide is reported as the mean of the positive detections and the associated error for that mean (see Section 3.7.2 for methodology).

6.4 Many of the tables are footnoted with the term "Plant Related Radionuclides".

Plant rela ted radionuclides are radionuclides that are produced in the reactor as a result of plant operation either through the activation or fission process.

7 - 1 7.0 HISTORICAL DATA TABLES Sample Statistics from Previous Environmental Sampling The mean, minimum value and maximum value were calculated for selected sample mediums and isotopes.

Special Considerations:

1. Sample data listed as 1969 was taken fr om the NINE MILE POINT, PREOPERA

-TION SURVEY, 1969 and ENVIRONMENTAL MONITORING REPORT FOR NIAGARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION, NOVEMBER, 1970.

2. Sample results listed as 1974 and 19 75 w ere taken from the respective Annual R adiological E nvironmental O perating R eports for Nin e Mile Point Unit 1 Nuclear Station

. Sample results listed as 1985 through the current year were taken from the respective James A. FitzPatrick Nuclear Power Plant Annual Radiological Environ

-mental Opera ting Reports.

3. Only measured values were used for statistical calculations.

4. The term MDL was used prior to 1979 to represent the concept of Lower Limit of Detection (LLD). MDL = Minimum Detectable Level.

8-1 8.0 QA/QC PROGRAM

8.1 PROGRAM

DESCRIPTION The Offsite Dose Calculation Manual (ODCM), Part 1, Section 5.3 requires that the licensee participate in an Interlaboratory Comparison Program. The Interlaboratory Comparison

Program shall include sample media for w hich samples are routinely collected and for which c omparison samples are commercially available. Participation in an Interlaboratory Comparison Program ensures that independent checks on the precision and accuracy of the measurement of radioactive materi al 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 JAF Environmental Laborato ry has engaged the services of two ind ependent laboratories to provide quality assurance comparison samples.

The two laboratories are Analytics, Incorporated in Atlanta, Georgia and the U.S.

Department of Commerce's National Institute of Standards and Technology (NIST) in Gaithersburg, Maryla nd. 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 using standard laboratory procedures. The results are submitted to A nalytics, which issues a statistical summary report. The JAFNPP Environmental Laboratory uses predetermined acceptance criteria methodology for evaluating the laboratory's

performance for Analytic's sample results.

In addition to the Analytics Program, the JAF Environmental Laboratory participates in the NEI/NIST Measurement Assurance Program. In 1987, the nuclear industry established a Measurement Assurance Program at the National Bureau of Standards (now

the National Institute of Standards and Technol ogy) to provide sponsoring nuclear utilities an independent verification, traceable to NIST, of their capability to make accurate measurements of radioactivity, as described in NRC Regulatory Guide 4.15.

The program includes distribution to sponsoring uti lities, approximately six times a year.

The samples are prepared by NIST to present specific challenges to participating laboratories. For 2005, the two mixed gamma samples analyzed tested the ability of the JAF Environmental Laboratory to accurately acco unt for coincidence summing from Cs

-134. NIST supplies sample media as blind sample spikes. These samples are prepared and analyzed by the JAF Environmental Laboratory and the results are submitted to the Entergy Nuclear Northeast representative, who use s predetermined acceptance criteria methodology for evaluating the laboratory's performance. The performance results along with the NIST Report of Test (Certifies what activities are present in the sample) are

forwarded to the laboratory.

8.3 ACCEPTANCE

CRITERIA Each sample result is evaluated to determine the accuracy and precision of the laboratory's analysis result. The sample evaluation method i s discussed below.

8.3.1 SAMPLE

RESULTS EVALUATION Samples provided by Analytics and NIST 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 r esult).

8-3 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 Using the appropriate row under the Error Resolution column in Table 8.3.1 below, a corresponding Ratio of Agreement interval is given.

The value for the ratio is then calculated.

Ratio = QC Result

of Agreement Ref erence Result If the value falls within the agreement interval, the result is acceptable.

-04.01 and was taken from the Criteria of Comparing Analytical Results (USNRC) and Bevington, P.R., Data Reduction and Error Analysis for the Physical Sciences, McGraw

-Hill, New York, (1969). The NRC method generally results in an acceptance range of approximately +/- 25% of the Known value when applied to sample results from the Analytics and NIST. Interlaboratory Comparison Pro gram. This method is used as the procedurally required assessment method and requires the generation of a nonconformity report when results are unacceptable.
