SUMMARY

The Annual Radiological Environmental Operating Report is published pursuant to Section 6.9.1.d of the Nine Mile Point Unit 1 Technical Specifications, Section 5.6.2 of the Nine Mile Point Unit 2 Technical Specifications and 10 CFR 50.4.

This report describes the Radiological Environmental Monitoring Program (REMP), the implementation, and the results obtained as required by Technical Specifications (TS) and the Offsite Dose Calculation Manuals (ODCM). The report also contains the analytical results tables, data evaluation, dose assessment, and data trends for each environmental sample media. Also included are results of the land use census, historical data and the Environmental Laboratory's performance in the Quality Assurance Intercomparison Program required by the Unit 1 and Unit 2 ODCM.

The REMP is a comprehensive surveillance program, which is implemented to assess the impact of site operations on the environment and compliance with 10CFR20 and 40CFR190.

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 2002, samples collected as part of the required monitoring program demonstrated that there is no significant radiological impact from the operation of either the Nine Mvile Point Unit 1 (NNTv1) or Nine Mile Point Unit 2 (NMP2) facilities. Cesium-137 was detected in several aquatic pathways at low levels and is directly attributed to fallout from past weapons testing. Tritium was detected in two surface water samples near the detection limit and are not considered to be plant related. The 2002 results for all pathways sampled are consistent with the previous five year historical results and exhibit no adverse trends.

In summary, the analytical results from the. 2002 REMP demonstrate that the routine operation of the facilities at the Nine Mile Point 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 either the NMPI or NMP2 hydrogen injection programs. The results of the REMP continue to demonstrate that the operation of the plants did not result in a significant measurable dose to a member of the general population, or adversely impact the environment-as a result of radiological effluents. The environmental program continues to demonstrate that the dose to a member of the public as a result of the operation of NMP1 and 1-1

NMP2 remains significantly below the federally required dose linits specified in 10CFR20 and 40CFRl90.

2.0 INTRODUCTION

Nine Mile Point Units 1 and 2 are operated by Nine Mile Point Nuclear Station, LLC. This report is submitted in accordance with Appendix A (Technical Specifications) Section 6.9.1.d to License DPR-63, Docket No. 50-220 for the Nine Mile Point Nuclear Station Unit 1 and Appendix A (Technical Specifications) Section 5.6.2 to License NPF-69, Docket No. 50-410 for the Nine Mile Point Nuclear Station Unit 2 for the calendar year 2002.

Nuclear Regulatory Commission (NRC) amendment #176 to the Niie Mile Point Unit 1 (NMP1) Technical Specifications, implemented on November 07, 2002, resulted in the relocation of the Radiological Environmental Monitoring Program (REMP) requirements from the NMP1 Technical Specifications to the NMP1 Offsite Dose Calculation Manual (ODCM). Nine Mile Point Unit 2 (NMP2) REMP requirements also reside within the NMP2 Offsite Dose Calculation Manual (ODCM). Throughout this report references will be made to TS/ODCM. This refers to the NMP1 Technical Specifications (TS) REMP requirements in effect from January 01, 2002 through November 06, 2002, the subsequent NMP1 TS amendment #176., effective November 07, 2002 and the NMP2 ODCM REMP requirements.

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 operations.

In 1968, the Niagara Mohawk Power Company began the required pre-operational environmental site testing program.

This pre-operational data serves as a reference point to compare later data obtained during reactor operation. In 1969, Nine Mile Point Unit 1, a 615 Megawatt Boiling Water Reactor (BWR) began full power operation. In 1975, the James A. FitzPatrick Nuclear Power Plant, a 883 Megawatt Boiling Water Reactor (BWR), currently owned and operated by Entergy, began full power operation.

In 1985, the individual station Effluent Technical Specifications were standardized to the generic Radiological Effluent Technical Specifications, much of which is common to both plants.

Data generated by the Radiological Environmental Monitoring Program (REMP) is shared, but each utility reviews and publishes their own annual report. In 1988, the Nine Mile Point Unit 2 reactor, a 1080 Megawatt BWR located between Unit 1 and Fitzpatrick, began full power operation. In 1995 Nine Mile Point Unit 2 was uprated to 1207 megawatts.

In summary, three Boiling Water Reactors, which generate approximately 2705 megawatts, have operated collectively at the Nine Mile Site since 1988.

A large data base of 2-1

environmental results for the exposure pathways has been collected and analyzed to determine the effect 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 7 miles east of the city of Oswego. The nearest metropolitan area is located approximately 23.8 miles southeast of the site. The reactors and support buildings occupy a small shoreline portion of the 900 acre 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 34% of the land devoted to agriculture.

2.3 PROGRAM OBJECTIVES The objectives of the Radiological Environmental Program are to:

1. Measure and evaluate the effects of plant operation on the environs and to verify the effectiveness of the controls of radioactive material sources.

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

3. Demonstrate compliance with the various environmental conditions and requirements of applicable state and federal regulatory agencies, including Technical Specifications and 40CFR Part 190.

2-2

SECTION 3.0 PROGRAM DESCRITON

3.0 PROGRAM DESCRIPTION To achieve the objectives listed in Section 2.3, an extensive sampling and analysis program is

.conducted every year. The NMPNS REMP consists of sampling and analysis of vaious media that include:

Shoreline Sediment Fish Surface Waters Air Milk

• Food Products In addition, direct radiation measurements are performed using thermoluminescent dosimeters (TIDs). These sampling programs are outlined in Table 3.0-1 and Table 3.0-2. The NMPNS REMP. sampling locations are selected and verified by an annual land use census.

The accuracy and precision of the program is assured by participation in an Interlaboratory Comparison Quality Assurance Program (ICP). In addition' to the participation 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 NMPNS and James A. FitzPatrick Nuclear Power Plant (JAFNPP). The site staff is assisted by a contracted environmental engineering company, EA Engineering, Science and Technology,-Inc. (EA).

3.1 SAMPLE COLLECTION METHODOLOGY 3.1.1 SHORELINE SEDIMENTS One kilogram of shoreline sediment is collected at one area of existing or potential recreational value. One sample is-also collected from a location beyond the influence of the site. Samples are collected as surface scrapings to a depth of approximately 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, Walleye and Smallmouth Bass, are collected twice per year, once in the spring and again in the fall.

Indicator samples are collected from a combination of the four on-site sample transects located off shore from the site. One set of control samples are collected 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 sample 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 segregated by species and 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.

3-13

3.1.3 SURFACE WATER Surface water 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.

Samples from the JAFNPP facility are composited from automatic sampling equipment which discharges into a compositing tank or bottles.

Samples are collected monthly from the compositor and analyzed for gamma emitters. Samples from the Oswego Steam Station are also obtained using automatic sampling equipment and collected in a holding tank.

Representative samples from this location are obtained weekly and are composited to form a monthly composite sample.

The monthly samples are analyzed for gamma emitting radionuclides.

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

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

Surface water sample locations are shown in Section 3.3 on Figure 3.3-4.

Sampling for ground water and drinking water, as found in Section D.3.5.1 of the Nine Mile Point Unit 2 Offsite Dose Calculation Manual (ODCM), was not required during 2002. There was no Groundwater Source in 2002 that was tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties were suitable for Contamination; therefore, Drinking Water was not a dose pathway during 2002.

3.1.4 AIR PARTICULATE / IODINE The air sampling stations required by the TS/ODCM are located in the general area of the site boundary. -The sampling stations are sited within a distance of 0.2 miles of the site boundary in sectors with the highest calculated deposition factor (D/Q) based -on historical meteorological data. These stations (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 TS/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 TS/ODCM is a control location designated as-Station R-5. Station R-5 is located 16.4 miles from the site in the NE meteorological sector.

In addition to the five TS/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 Dl, 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 stations are located in the ESE, SSE, and S sectors and range in distance from 7.2 to 9.0 miles. These are designated as Off-Site Stations D2, E and F respectively.

Each station collects airborne particulates using glass fiber filters (47 millimeter diameter) 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 sample discharge. Gross beta analysis is performed on each particulate filter.

Charcoal cartridges are analyzed for radioiodine using gamma spectral analysis.

The particulate filters are composited monthly by location and analyzed for gamma emitting radionuclides.

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 (gamna dose) in the environment. Environmental TLDs are supplied and processed quarterly by the JAFNPP Environmental Laboratory. The laboratory utilizes a Panasonic based system using UD-814 dosimeters which are constructed of rectangular teflon wafers impregnated with 25%

CaSO4:Dy phosphor. Each dosimeter contains three calcium sulfate elements and one lithium borate element.

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

TLD Geographical Category On-site Description TLDs placed at various locations within the Site Boundary and are not required by the TS/ODCM.

(TLD locations comprising this group are: 3, 4, 5, 6, 7*, 23*, 24, 25, 26, 27, 28, 29, 30, 31, 39, 47, 18*, 103, 106 and 107)

Site Boundary Off-site Sector An inner ring of TLDs placed in the general area of the Site Boundary in each of the sixteen meteorological sectors.

This category is required by TSIODCM. (TLD locations comprising this group are: 75*, 76*, 77*, 78*, 79*, 80*, 81*, 82*, 83*, 84, 7*, 18*,

85*, 86*, 87* and 23*)

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 TS/ODCM. (TLD locations comprising this group are 88*, 89*,

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

3-16

TLD Geographical Category Description Special Interest TLDs placed in Special Interest areas of high population density and use. These TLDs are located at or nearlarge industrial sites, schools, or nearby towns or communities. This category is required by the TS/ODCM. (TLD locations comprising this group are: 9, 10, 11, 12, 13, 15*, 19, 51, 52, 53, 54, 55, 56*, 58*, 96*, 97*, 98*,

99, 100, 101, 102, 108, and 109)

Control TLDs placed in areas beyond significant influence of the site and plant operations. These TLDs are located to the SW, S and NE of the site at distances of 12.6 to 24.7 miles. This category is also required by the TS/ODCM. (TLD locations comprising this group are 14*, 49*, 8, 111, 113)

TLD location required by TS/ODCM Although the TS/ODCM require a total of 32 TLD stations, environmental TLDs are also placed at additional locations, not required by the TS/ODCM, within the On-site, Special Interest and Control TLD categories to supplement the TS/ODCM required direct radiation readings.

Two dosimeters are placed at each TLD monitoring location.

The TLDs are sealed in polyethylene packages to ensure dosimeter integrity and placed in open webbed plastic holders and attached to supporting structures, such as utility poles.

Environmental TLD locations are shown in Section 3.3, Figures 3.3-2 and 3.3-3.

3.1.6 ILK Milk samples are routinely collected from six farms during the year. These farms include five indicator locations and one control location. Samples are collected twice per month, April through December, and each sariple is analyzed for gamma emitting radionuclides-and I-131.

Samples are collected in January, February and March in-the event that I-131 is detected in November and December of the preceding year.

3-17

The selection of milk sample locations is based on maximum deposition calculations (D/Q).

Deposition values are generated using average historical meteorological data for the site. The TS/ODCM require three sample locations within 5.0 miles of the site with the highest calculated deposition value. During 2002 there were no milk sample locations within 5.0 miles that were suitable for sampling based on production capabilities. There were however, five optional locations beyond five miles that were sampled as indicator locations for the 2002 routine milk sampling program.

The TS/ODCM also requires that a sample be collected from a location nine to twenty miles from the site and in the least prevalent wind direction. This location is in the SSW sector and serves as the control location.

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

The samples are chilled, preserved and shipped fresh to the analytical laboratory within thirty-six hours of collection in insulated shipping containers.

The milk sample locations -are shown in Section 3.3, Figure 3.3-4. (Refer to Section 3.3, Table 3.3-1 for location designation and descriptions.)

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 locations. Sample locations are selected from 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 product locations are shown in Section 3.3, Figure 3.3-5.

3-18

3.2 ANALYSES PERFORMED The majority of environmental sample, analyses are performed by the James A. FitzPatrick

Nuclear Power Plant (JAFNPP) Environmental Laboratory. Tritium analyses for samples collected during 2002 were performed by Framatome ANP Environmental Laboratory. The following samples are analyzed at the JAFNPP Environmental Lab:

Shoreline Sediment - gamma spectral analysis Fish - gamma spectral analysis Surface Water Monthly Composites - gamma spectral analysis /I-131 Air Particulate Filter - gross beta

• Air Particulate Filter Composites - gamma spectral analysis Airborne Radioiodine - gamma spectral analysis Direct Radiation - Thermoluminescent Dosimeters (ILDs)

• Milk-gamma spectral analysis and l-131 Food Products (Vegetation) - gamma spectral analysis Special Samples (soil, food products, bottom sediment, etc.) - gamma spectral analysis 3.3 SAMPLE LOCATIONS Section 3.3 provides maps illustrating sample locations.

Sample locations referenced as letters and numbers on the report period data tables are consistent with designations plotted on the maps.

This section also contains an environmental sample location reference table (Table 3.3-1).

This table contains the following information:

3.4 LAND USE CENSUS The TS/ODCM require that a milch animal census and a residence census be conducted annually. Mlch animals are defined as any animal that is routinely used to provide milk for human consumption.

The milch animal census is an estimation of the number of cows and goats within an approximate ten mile radius of the Nine Mile Point Site. The census is done once per year in the summer. It is conducted by sending questionnaires to previous milch animal owners, and by road surveys to locate any possible new owners. In the event that questionnaires are not 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 TS/ODCM if broadleaf vegetation sampling and analysis is performed.

3-30

3.5 CHANGES TO THE REhlP PROGRAM The following changes were implemented during the 2002 sampling program:

A.

Food Product/Vegetation The food product/vegetation sample locations are evaluated each sampling season based on meteorology and product availability.

The following sample location changes were implemented in 2002:

• The sampling program did not utilize food product vegetation locations (Battles, Hail, Lee, and Vitullo) sampled in 2001 for the 2002 sampling program. These locations were not sampled due to the general unavailability of samples.

The 2002 Land Use Census identified a new garden location that was sampled as an optional location due to limited produce availability. The garden is located in the east sector (96°) at a distance of 1.7 miles.

There were no changes to the program outlined by the TS/ODCM.

3-31

3.6 DEVIATION AND EXCEPTIONS TO THE PROGRAM Exceptions to the 2002 sample program concern those samples or monitoring requirements

'which are required by the TS/ODCM. This section satisfies the reporting requirements of Section D6.9.1.d of the Nine Mile Point Unit 1 Offsite Dose Calculation Manual and Section D4.1.2 of the Nine Mile Point Unit 2 Offsite Dose Calculation Manual.

A.

TS/ODCM PROGRAM DEVIATIONS The following are deviations from the program specified by the TS/ODCM:

B.

AIR SAMPLING STATION OPERABILITY ASSESSMENT The TS/ODCM required air sampling program consists of 5 individual sampling locations. The collective operable time period for the air monitoring stations was 3-32

43,787 hours0.00911 days <br />0.219 hours <br />0.0013 weeks <br />2.994535e-4 months <br /> out of a possible 43,800. The air sampling availability factor for the report period was 99.97%.

3-33

3.7 STATISTICAL METHODOLOGY There are a number of statistical calculation methodologies used in evaluating the data from the environmental monitoring program.

These methodologies include determination of standard deviation, the mean and associated error for the 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

Xi

~i=l N

Where, X

= estimate of the mean.

i

= individual sample, i.

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

Xi

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

3-34

B.

Standard Deviation S= E(Xi-)2M (N -1)

Where, X = mean for the values of X s = standard deviation for the sample population.

3.7.2 ESTINATION OF THE MEAN AND THE ESTIMATED ERROR FOR THE MEAN In accordance with program policy, two recounts of samples are performed when the initial count indicates the presence of a plant related radionuclide(s).

When a radionuclide is positively identified in two or more counts, the analytical result for the radionuclide is reported as the mean of the positive detections and the associated propagated error for that mean. In cases where more than one positive sample result is available, the mean of the sample results and the estimated error for the mean are reported in the Annual Report.

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

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

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

3.7.3 LOWER LIMIT OF DETECTION (LLD)

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

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

4.66 Sb LLD-(E) (V) (2.22) (Y) exp (-XAt)

Where:

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

Sb

=

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

E

=

the counting efficiency (in counts per disintegration);

V

=

the sample size (in units of mass or volume);

2.22 =

the number of disintegrations per minute per picocurie; Y

=

the fractional radiochemical yield (when applicable);

X

=

the radioactive decay constant for the particular radionuclide; At =

the elapsed time between sample collection (or end of the sample collection period) and time of counting.

3-37 1

The TS/ODCM ILD formula assumes that:

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

The count rate of the background is approximately equal to the count rate of the sample.

In the TS/ODCM program, LLDs are used to ensure that minimum acceptable detection capabilities are met with specified statistical confidence levels (95% detection probability with 5% probability of a false negative). Table 3.8-1 lists the TS/ODCM program required LLDs for specific media and radionuclides as specified by the NRC.

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

3.8 COMlPLIANCE WITH REQUIRED LOWER LIrvllS OF DETECTION (LLD)

Tables D 4.6.20-1 and D 3.5.1-3 of the Nine Mile Point Unit 1 Offsite Dose Calculation Manual and Nine Mile Point Unit2 Offsite Dose Calculation Manual, respectively, specify the detection capabilities for environmental sample analysis (See Report Table 3.8-1).

The reporting requirements of Nine Mile Point Unit 1 Offsite Dose Calculation Manual, Section D 6.9.1.d and Nine Mite Point Unit 2 Offsite Dose Calculation Manual Section D 4.1.2 require that a discussion of all analyses for which the LLDs required by Tables D 4.6.20-1 and D 3.5.1-3 were not achieved be included in the Annual Radiological Environmental Operating Report. Section 3.8 is provided pursuant to this requirement.

All sample analyses performed in 2002, as required by the TS/ODCM, achieved the Lower Limit of Detection (LLD) specified by ODCM Tables D 4.6.20-1 and D 3.5.1-3.

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

3.9.1 The Nuclear Regulatory Connission (NRC):

The NRC, in 10CFR20.1301 limits the levels of radiation in unrestricted areas resulting from the possession or use of radioactive materials such that they limit any individual to a dose of:

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

In addition to this dose timit, 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 10CFR50, 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 gases 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.

3-41

3.9.2 Environmental Protection Agency (EPA)

The EPA, in 40CFR190.10 Subpart B, sets forth the environmental standards for the uranium fuel cycle. During normal operation, the annual dose to any member of the public from the entire uranium fuel cycle shall be limited to; less than or equal to 25 mrem per year to the whole body, less than or equal to 75 mrem per year to the thyroid, and

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