1. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Oyster Creek Generating Station (OCGS) by Exelon Nuclear covers the period 01 January 2008 through 31 December 2008. During that time period, 1372 analyses were performed on 1165 samples. In assessing all the data gathered for this report and comparing these results with historical data, it was concluded that the operation of OCGS had no adverse radiological impact on the environment.

Surface and drinking water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No tritium and no fission or activation products were detected in any of the surface or drinking water samples collected as part of the Radiological Environmental Monitoring Program during 2008.

Fish (predator and bottom feeder), clams, crabs, and sediment samples were analyzed for concentrations of gamma emitting nuclides. No OCGS-produced fission or activation products were detected in fish, clams, crabs or sediment.

Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Cosmogenic Be-7 was detected at levels consistent with those detected in previous years. No fission or activation products were detected.

High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity.

Strontium-89 and strontium-90 and gamma analyses were performed on quarterly composites of air particulate samples. All strontium-89 and strontium-90.results were below the minimum detectable activity.

Vegetation samples were analyzed for gamma emitting nuclides, strontium-89, and strontium-90. Concentrations of naturally occurring K-40 were consistent with those detected in previous years. All strontium-89 results were below the minimum detectable activity. Strontium-90 activity was detected at levels consistent with those detected in previous years at both control and indicator stations, and can be attributed to historical nuclear weapons testing and the Chernobyl accident.

Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters. Similar to previous years, there was no indication of an increase in offsite direct radiation dose rates with the exception of a few locations at or near the site boundary where public access is restricted.

The maximum dose to any member of the public attributable to radioactive effluents and direct radiation from the OCGS was less than the 25 mRem/year limit established by the United States Environmental Protection Agency.

II. Introduction The Oyster Creek Generating Station (OCGS), consisting of one boiling water reactor owned and operated by Exelon, is located on the Atlantic Coastal Plain Physiographic Province in Ocean County, New Jersey, about 60 miles south of Newark, 9 miles south of Toms River, and 35 miles north of Atlantic City. It lies approximately 2 miles inland from Barnegat Bay. The site, covering approximately 781 acres, is situated partly in Lacey Township and, to a lesser extent, in Ocean Township. Access is provided by U.S. Route 9, passing through the site and separating a 637-acre eastern portion from the balance of the property west of the highway. The station is about 11/4 mile west of the highway and 11/4 miles east of the Garden State Parkway. The site property extends about 21/2miles inland from the bay; the maximum width in the north-south direction is almost 1 mile. The site location is part of the New Jersey shore area with its relatively flat topography ,and extensive freshwater and saltwater marshlands. The South Branch of Forked River runs across the northern side of the site and Oyster Creek partly borders the southern side.

A preoperational Radiological Environmental Monitoring Program (REMP) for OCGS was established in 1966, and continued for two years prior to the plant becoming operational in 1969. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Global Dosimetry, and Environmental Inc.

(Midwest Labs) on samples collected during the period 01 January 2008 through 31 December 2008.

A. Objectives of the REMP The objectives of the REMP are to:

1. Determine whether any significant increase occurs in the concentration of radionuclides in major pathways.

2. Identify and evaluate the buildup, if any, of radionuclides in the local environment, or any changes in normal background radiation levels.

3. Verify the adequacy of the plant's controls for the release of radioactive materials.

4. Fulfill the obligations of the radiological surveillance sections of Oyster Creek's Offsite Dose Calculation Manual (ODCM).

2

B. Implementation of the Objectives The implementation of the objectives is accomplished by:

1. Identifying significant exposure pathways.

2. Establishing baseline radiological data for media within those pathways.

3. Continuously monitoring those media before and during Station operation to assess Station radiological effects (if any) on man and the environment.

C. Discussion

1. General Program The Radiological Environmental Monitoring Program (REMP) was established in 1966, three years before the plant became operational. This preoperational surveillance program was established to describe and quantify the radioactivity, and its variability, in the area prior to the operation of OCGS. After OCGS became operational in 1969, the operational surveillance program continued to measure radiation and radioactivity in the surrounding areas.

A variety of environmental samples are collected as part of the REMPat OCGS. The selection of sample types is based on the established pathways for the transfer of radionuclides through the environment to humans. The selection of sampling locations is based on sample availability, local meteorological and hydrological characteristics, local population characteristics, and land usage in the area of interest. The selection of sampling frequencies for the various environmental media is based on the radionuclides of interest, their respective half-lives, and their behavior in both the biological and physical environment.

2. Preoperational Surveillance Program The federal government requires nuclear facilities to conduct radiological environmental monitoring prior to constructing the facility. This preoperational surveillance program is aimed at collecting the data needed to identify pathways, including selection of the radioisotope and sample media combinations to be included in the environmental surveillance program conducted after facility operation begins. Radiochemical analyses performed on the 3

environmental samples should include not only those nuclides expected to be released during facility operation, but should also include typical radionuclides from nuclear weapons testing and natural background radioactivity. All environmental media with a potential to be affected by facility operation as well as those media directly in the major pathways, should be sampled on at least an annual basis during the preoperational phase of the environmental surveillance program.

The preoperational surveillance design, including nuclide/media combinations, sampling frequencies and locations, collection techniques, and radioanalyses performed, should be carefully considered and incorporated in the design of the operational surveillance program. In this manner, data can be compared in a variety of ways (for example, from year to year, location to location, etc.) in order to detect any radiological impact the facility has on the surrounding environment. Data collection during the preoperational phase should be planned to provide a comprehensive database for evaluating any future changes in the environment surrounding the nuclear facility.

OCGS began its preoperational environmental surveillance program three years before the plant began operating in 1969.

Data accumulated during those early years provide an extensive database from which environmental monitoring personnel are able to identify trends in the radiological characteristics of the local environment. The environmental surveillance program at OCGS will continue after the plant has reached the end of its economically useful life and decommissioning has begun.

3. Consideration of Plant Effluents Effluents are strictly monitored to ensure that radioactivity released to the environment is as low as reasonably achievable and does not exceed regulatory limits. Effluent control includes the operation of monitoring systems, in-plant and environmental sampling and analyses programs, quality assurance programs for effluent and environmental programs, and procedures covering all aspects of effluent and environmental monitoring.

Both radiological environmental and effluent monitoring indicate that the operation of OCGS does not result in significant radiation exposure of people or the environment surrounding OCGS and is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency 4

(EPA).

There were no liquid radioactive effluent releases from the OCGS during 2008. Utilizing gaseous effluent data, the maximum hypothetical dose to any individual in the south-east sector of the plant (sector of predominant wind direction) during 2008 was calculated using a mathematical model, which is based on the methods defined by the U.S. Nuclear Regulatory Commission.

These methods accurately determine the types and quantities of radioactive materials being released to the environment.

The maximum hypothetical calculated organ dose (thyroid) from iodines and particulates to any individual due to gaseous effluents was 3.58E-3 mRem (0.00358 mRem) which was approximately 0.00024 percent of the annual limit. The maximum hypothetical calculated whole body dose to any individual due to gaseous effluents was 4.22E-4 mRem (0.000422 mRem) which was 0.000084 percent of the annual limit.

The total maximum hypothetical organ dose (thyroid) due to all radiological effluents of 3.58E-3 mRem (0.00358 mRem) received by any individual from gaseous effluents from the Oyster Creek Generating Station for the reporting period is more than 83,000 times lower than the dose the average individual in the Oyster Creek area received from background radiation, including that from radon, during the same time period. The background radiation dose averages approximately 300 mRem per year in the Central New Jersey area, which includes approximately 200 mRem/year from naturally occurring radon gas.

During 2008, the maximum direct radiation dose potentially attributable to the operation of Oyster Creek beyond the site boundary in the southeast sector, as shown by offsite thermoluminescent dosimeter (TLD) readings, was 1.8 mRem/year at Station 109. Therefore, the maximum combined direct radiation and whole body effluent dose potentially attributable to Oyster Creek in the south-east sector during 2008 was 1.800422 mRem, or approximately 7.2 percent of the 40 CFR 190 limit of 25 mRem/year.

Additionally, comparison of environmental sampling results to iodine and particulate gaseous effluents released, showed no radioactivity attributable to the operation of OCGS. Both elevated and ground-level release paths were considered in this review, with total iodines released of 1.58 mCi and total particulates with half-5

lives greater than 8 days released of 0.339 mCi. (1 mCi is one/one-thousandth of a Ci).

Ill. Program Description A. Sample Collection Samples for the OCGS REMP were collected for Exelon by on-site personnel and Normandeau Associates, Incorporated. This section describes the general collection methods used to obtain environmental samples for the OCGS REMP in 2008. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-i, B-2, and B-3, Appendix B. The collection procedures are listed in Table B-3.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, fish, clams, crabs, and sediment. One gallon water samples were collected monthly from two surface locations (33 and 94), semiannually at two surface water locations (23 and 24), and quarterly from four drinking water wells(l, 37, 38, and 39). Control locations were 94 and 37. All samples were collected in plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprising the flesh of two groups, bottom feeder and predator, were collected semiannually at three locations (33, 93 and 94 (control). Clams were collected semiannually from three locations (23, 24, and 94 (control)). One annual crab sample was collected from one location (93). Sediment samples were collected at four locations semiannually (23, 24, 33, and 94 (control)).

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate and airborne iodine. Airborne iodine and particulate samples were collected and analyzed weekly at eight locations (C, 3, 20, 66, 71, 72, 73, and 111). The control location was C. Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis.

6

Terrestrial Environment The terrestrial environment was evaluated by performing radiological analyses on samples of garden vegetation.

No commercial dairy operations and no dairy animals producing milk for human consumption are located within a 5 mile radius of the plant.

Therefore, vegetation samples were collected in lieu of milk. Vegetation samples were collected, when available, at three locations (35, 36, and 66). Station 36 was the control location. All samples were collected in 18" x 24" new unused plastic bags and shipped promptly to the laboratory.

Ambient Gamma Radiation Direct radiation measurements were made using Panasonic Model 814 calcium sulfate (CaSO 4 ) thermoluminescent dosimeters (TLD). The TLDs were placed on and around the OCGS site and were categorized as follows:

A site boundary ring consisting of 19 locations (1, T1, 51, 52, 53, 54, 55, 56, 57, 58, 59, 61, 62, 63, 64, 65, 66, 112, and 113) near the site boundary.

An intermediate distance ring consisting of 31 locations (4, 5, 6, 8, 9, 22, 46, 47, 48, 68, 73, 74, 75, 78, 79, 82, 84, 85, 86, 98, 99, 100, 101,102, 103, 104, 105, 106, 107, 109, and 110) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.

Special interest stations consisting of 9 locations (3, 11, 71, 72, 81, 88, 89, 90, and 92) representing special interest areas such as population centers, state parks, etc.

Background (Control) stations consisting of two locations (C and 14) greater than 20 miles distant from the site.

Indicator TLDs were placed systematically, with at least one station in each of 16 meteorological compass sectors in the general area of the site boundary. TLDs were also placed in each meteorological sector in the 3 3/4 to 5 mile range, where reasonable highway access would permit, in areas of public interest and population centers. Background locations were located greater than twenty miles distant from the OCGS and generally in an upwind direction from the OCGS.

Two TLDs - each comprised of three CaSO4 thermoluminescent 7

phosphors enclosed in plastic - were placed at each location approximately three to eight feet above ground level. The TLDs were exchanged quarterly and sent to Global Dosimetry for analysis.

B. Sample Analysis This section describes the general analytical methodologies used by TBE and Environmental Inc. (Midwest Labs) to analyze the environmental samples for radioactivity for the OCGS REMP in 2008. The analytical procedures used by the laboratories are listed in Table B-3.

In order to achieve the stated objectives, the current program includes the following analyses:

1. Concentrations of beta emitters in air particulates.

2. Concentrations of gamma emitters in surface and drinking water, fish, clams, crabs, sediment, air particulates, and vegetation.

3. Concentrations of tritium in surface and drinking water.

4. Concentrations of 1-131 in air iodine cartridges.

5. Concentrations of strontium in air particulates and vegetation.

6. Ambient gamma radiation levels at various locations around the OCGS.

C. Data Interpretation For trending purposes, the radiological and direct radiation data collected during 2008 were compared with data from past years. The results of environmental sampling show that radioactivity levels have not increased from the background radioactivity detected prior to the operation of OCGS.

The operation of OCGS continues to have no measurable radiological impact upon the environment.

Several factors were important in the interpretation of the data:

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation 8

represents a "real" signal. The LLD is intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criterion for the presence of activity. All analyses were designed to achieve the required OCGS detection capabilities for environmental sample analysis.

The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2. Net Activity Calculation and Reportingq of Results Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations may result in sample activity being lower than the background activity, which results in a negative number.

An MDC was reported in all cases where positive activity was not detected.

Gamma spectroscopy results for each type of sample were grouped as follows:

For surface and drinking water 12 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-140, and La-140 were reported.

For fish eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-1 37 were reported.

For clams eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-1 37 were reported.

For crabs eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-137 were reported.

For sediment seven nuclides, Be-7, K-40, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-134, and Cs-1 37 were reported.

For air iodine cartridges one nuclide, 1-131 was reported.

For vegetation seven nuclides, Be-7, K-40, 1-131, Cs-134, Cs-137, 9

Ba-140, and La-140 were reported.

Means and standard deviations of the results were calculated. The standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.

D. Program Exceptions For 2008 the OCGS REMP had a sample recovery rate in excess of 99%.

Exceptions are listed below:

1. Only two fish samples were available (3 samples are desired, but not required) for spring collection for the following period and location:

04/15/2008 - 04/16/2008, Location 33

2. Air particulate and air iodine samples were not available because the main fuse box had been turned off (vandalism suspected) for the following period and location:

01/09/2008 - 01/16/2008, Location 20

3. Air particulate and air iodine sampler lost power for a portion of time due to a blown breaker. Sampler did not run long enough to constitute a valid sample for the following period and location:

06/25/2008 - 07/01/2008, Location 73

4. Air particulate and air iodine sampler pump was not running for a portion of time. Although the hour timer was still running, it is not known how long the pump ran. Air sample was collected, but should not be considered valid for the following period and location:

10/15/2008 - 10/22/2008, Location C

5. No broadleaf vegetation sample was collected due to seasonal availability for the following periods and locations: *NOTE 06/08/2008, Location 35 06/08/2008, Location 36 06/08/2008, Location 66

6. A cabbage QC sample was collected in September to replace a sample collected in August that did not arrive at the primary lab:

08-09/2008, Location 36

7. One of the two TLDs at Location 98 was missing during collection (vandalism suspected, the remaining TLD was available for analysis) for the following period and location:

07/1'6/2008 - 10/08/2008, Location 98 10

8. Both TLDs were missing during collection for the following periods and locations:

01/08/2008 - 04/16/2008, Location 6 04/16/2008 - 07/16/2008, Location 105

• NOTE: Per the Oyster Creek ODCM, if garden vegetation samples are unobtainable due to any legitimate reason, the missed sample will be documented in the annual report, with no further actions necessary.

Program exceptions are tracked and investigated to understand the causes of the program exception. Sampling and maintenance errors are reviewed with the personnel involved to prevent recurrence.

The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation.

E. Program Changes Air sampling Station 111 was added to the REMP during the first quarter of 2008.

TLD sampling Stations 100, 101, 102, 103, 104, 105, 106, 107, 109 and 110 were added to the REMP in the first quarter of 2008.

TLD sampling Stations 112 and 113 were added to the REMP in the third quarter of 2008.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were taken via grab sample methodology at two locations (33 and 94) on a monthly schedule. In addition, grab samples were collected semi-annually at two locations (23 and 24). Of these locations 23, 24, and 33, located downstream, could be affected by Oyster Creek's effluent releases. The following analyses were performed:

11

Tritium Samples from all locations were analyzed for tritium activity (Table C-1.1, Appendix C). No tritium activity was detected. Data from this year indicates that surface water tritium concentrations remain very low and not significantly different from recent previous years.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-1.2, Appendix C). All nuclides were less than the MDC.

Surface water sampling began in 1966, and the samples were analyzed for tritium as well as other radioactivity. During this preoperational program, tritium was detected at an average concentration of 1.05E+3 pCi/liter. At that time, counting instrumentation was not as sensitive as it now, and the minimum detectable concentration was 1E+3 pCi/liter versus 2E+2 pCi/liter used today. By comparing the 2008 sampling results to the decay corrected average preoperational concentration reported in the 2007 Annual Radiological Environmental Operating Report (11.11 E+2 pCi/liter), it can be seen that the inventory of tritium in the environment is due to fallout from past atmospheric nuclear weapons testin.g and Chernobyl, and is decreasing with time.

2. Drinking water Quarterly samples were composited from monthly grab samples from four drinking water wells (1, 37, 38, and 39). Station 1, because it is located on the OCGS site, could potentially be affected by radioactive releases from the plant. Station 38, the Ocean Township Municipal Utility Authority Well, could potentially be affected by effluent releases from the OCGS. Given its distance from the facility (1.6 miles) and depth (approximately 360 feet),

however, the probability of any OCGS related impacts is very small.

Stations 37 and 39, Lacey Township Municipal Utility Authority wells, are not likely to be impacted by effluents from the OCGS.

These wells are located generally up-gradient of the regional groundwater flow direction (southeast). In addition, because of their depth (> 200 feet) and distance from the site (2.2 and 3.5 miles respectively), they are unlikely to be affected by OCGS operations.

The following analyses were performed:

12

Tritium Quarterly samples from all locations were analyzed for tritium activity (Table C-11.1, Appendix C). No tritium activity was detected.

Gamma SpectrometrV Samples from all locations were analyzed for gamma emitting nuclides (Table C-11.2, Appendix C). All nuclides were less than the MDC.

Drinking water was sampled during the preoperational program and throughout the 38 years of the plant's operational program. Tritium sampling results during the preoperational years, yielded results all less than the minimum detectable concentration of 1E+3 pCi/liter.

2008 results are all less than the current MDC of 200 pCi/liter.

3. Fish Fish samples comprised of American eel and flounder (bottom feeder) and striped bass, bluefish, sea trout, and perch (predator) were collected at three locations (33, 93, and 94) semiannually.

Locations 93 and 33 could be affected by Oyster Creek's effluent releases. The following analysis was performed:

Gamma Spectrometry The edible portions of fish samples from three locations were analyzed for gamma emitting nuclides (Table C-111.1, Appendix C).

Naturally occurring potassium-40 was found at all stations and ranged from 3,080 to 5,340 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.

No fish were sampled during the preoperational sampling program for OCGS.

4. Clams and Crabs Clams were collected at three locations (23, 24, and 94) semiannually. Crabs were collected at one location (93) annually.

Locations 23, 24, and 93 could be affected by Oyster Creek's effluent releases. The following analysis was performed:

13

Gamma Spectrometry The edible portions of clam samples from all three locations were analyzed for gamma emitting nuclides (Table C-111.2, Appendix C).

Naturally occurring potassium-40 was found at all stations and ranged from 1,610 to 2,320 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found. Historical levels of Co-60 in clams are shown in Figure C-1, Appendix C.

Preoperational clam sample results for potassium-40 ranged from 600 to 9,800 pCi/kg wet, which are consistent with current sample results.

The edible portions of crab samples from one location were analyzed for gamma emitting nuclides (Table C-111.2, Appendix C).

Naturally occurring potassium-40 was found at a concentration of 2,730 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.

Crabs were not sampled during the preoperational years of the OCGS environmental monitoring program.

5. Sediment Aquatic sediment samples were collected at four locations (23, 24, 33, and 94) semiannually. Of these locations, stations 23, 24, and 33 located downstream, could be affected by Oyster Creek's effluent releases. The following analysis was performed:

Gamma Spectrometry Sediment samples from all four locations were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). The only radionuclide detected was naturally occurring K-40.

Potassium-40 was found at all stations and ranged from 505 to 15,100 pCi/kg dry. No fission or activation products were found.

Figure C-3, Appendix C graphs Cs-137 concentrations in sediment from 1984 through 2008 and figure C-2, Appendix C graphs Co-60 concentrations in sediment from 1984 through 2008.

While aquatic sediment sampling was part of the preoperational program, samples were not analyzed for gamma emitting nuclides 14

until 1981.

In conclusion, the 2008 aquatic monitoring results for surface water, drinking water, fish, clams and crabs, and aquatic sediment showed only naturally occurring radioactivity and were consistent with levels measured prior to the operation of OCGS, and with levels measured in past years. No radioactivity attributable to activities at OCGS was detected in any aquatic samples during 2008 and no adverse long-term trends are shown in the aquatic monitoring data.

B. Atmospheric Environment

1. Airborne

a. Air Particulates Continuous air particulate samples were collected from eight locations on a weekly basis. The eight locations were separated into three groups: Group I represents locations near the OCGS site boundary (20, 66 and 111), Group II represents the locations at an intermediate distance from the OCGS site (71, 72, and 73), and Group III represents the control and locations at a remote distance from OCGS (C and 3). The following analyses were performed:

Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table C-V.1 and C-V.2, Appendix C).

Detectable gross beta activity was observed at all locations.

Comparison of results among the three groups aids in determining the effects, if any, resulting from the operation of OCGS. The results from the Site Boundary locations (Group I) ranged from <6 to 29 E-3 pCi/m 3 with a mean of 15 E-3 pCi/m 3 . The results from the Intermediate Distance locations (Group II) ranged from <7 to 30 E-3 pCi/m 3 with a mean of 15 E-3 pCi/m . The results from the Distant locations (Group Ill) ranged from <7 to 35 E-3 pCi/m 3 with a mean of 15 E-3 pCi/m 3 . The similarity of the results from the three groups indicates that there is no relationship between gross beta activity and distance from the OCGS. These results are consistent with data from previous years and indicate no effects from the operation of OCGS (Figures C-4 and C-5, Appendix C).

15

Air sample filters have been analyzed for gross beta activity since the inception of the preoperational environmental monitoring program in 1966. The preoperational data values ranged from 1.90E-2 to 2.77E-1 pCi/m 3 . 2008 gross beta activity values ranged from <6E-3 to 35E-3 pCi/m 3 . The 2008 results are consistent with historical operational data (Figure C-5, Appendix C) and fall within the range of results observed during the preoperational period.

Strontium-89 and Strontium-90 Weekly samples were composited quarterly and analyzed for strontium-89 and strontium-90 (Table C-V.3, Appendix C).

No strontium was detected in any of the samples. These results are consistent with historical operational data. The preoperational environmental monitoring program did not include analysis of air samples for strontium-89 and strontium-90.

Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-V.4, Appendix C).

Naturally occurring Be-7 due to cosmic ray activity was detected in all samples. The values ranged from 37 to 128 E-3 pCi/m 3 . All other nuclides were less than the MDC.

These results are consistent with historical operational data.

The preoperational environmental monitoring program did not include analysis of air samples for gamma emitting nuclides.

b. Airborne Iodine Continuous air samples were collected from eight (C, 3, 20, 66, 71, 72, 73, 111 ) locations and analyzed weekly for 1-131 (Table C-VI.1, Appendix C). Consistent with historical operational data, all results were less than the MDC.

The preoperational environmental monitoring program for OCGS did not include analysis of air media for iodine-1 31.

In conclusion, the atmospheric monitoring data are consistent with preoperational and prior operational data and show no long-term trends in the environment attributable to 16

the operation of OCGS.

2. Terrestrial

a. Vegetation Samples were collected from three locations (35, 36, and 66) when available. The following analyses were performed:

Strontium-89 and Strontium-90 Vegetation samples from all locations were analyzed for concentrations of strontium-89 and strontium-90 (Table C-VII.l, Appendix C). All strontium-89 results were less than the MDC. Strontium-90 was detected in 32 of 35 samples.

The values ranged from 2 to 37 pCi/kg wet, which is consistent with historical data. The mean strontium-90 concentration at control location 36 (15 pCi/kg wet) was higher than the mean concentrations observed at indicator stations 35 and 66 (12 and 10 pCi/kg wet respectively).

These results indicate that the strontium-90 detected in vegetation samples is attributable to fallout from past atmospheric nuclear weapons testing and the Chernobyl accident.

Gamma Spectrometry Vegetation samples from locations 35, 36, and 66 were analyzed for concentrations of gamma emitting nuclides (Table C-VII.l1, Appendix C). Naturally occurring K-40 activity was found in all samples and ranged from 1,840 to 5,300 pCi/I. All other nuclides were less than the MDC.

Preoperational vegetation sample analyses did not include strontium analyses, or gamma spectroscopy.

In conclusion, terrestrial monitoring results for vegetation samples during 2008 showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and Chernobyl.

The radioactivity levels detected were consistent with levels measured in past years, and no radioactivity attributable to activities at OCGS was detected in any terrestrial samples.

The terrestrial monitoring data show no adverse long-term trends in the terrestrial environment.

17

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic Model 814 (CaSO 4 ) thermoluminescent dosimeters. Sixty-one TLD locations were monitored around the site. Results of non-background corrected TLD measurements are summarized in Tables C-VIII.1 to C-VIII.3, and Figures C-6 and C-7, Appendix C.

The non-background corrected TLD measurements ranged from 11.7 to 23.7 mR/standard quarter. In order to correct these results for background radiation, the mean of the dose rates measured at the background TLD stations (C and 14) was subtracted from the dose measured at each indicator station. The maximum annual background corrected dose was 18.5 mR/year at Station 55, located near the site boundary, 0.3 miles west of the OCGS. This TLD is located in an area where public access is restricted. All background corrected TLD measurements were less than the 40 CFR 190 limit of 25 mR/year.

Similar to previous years, there was no strong relationship between dose measured with TLDs and distance from the OCGS, and the mean background dose exceeded the mean indicator dose in three of the four quarterly monitoring periods during 2008.

The preoperational environmental monitoring program utilized film badges, the results of which are not comparable with the doses measured using thermoluminescent dosimeters during the operational REMP.

In conclusion, the 2008 TLD results are consistent with past operational measurements of direct radiation, and demonstrate that the OCGS continues to be in compliance with the 40 CFR 190 limit on maximum dose to the public.

D. Land Use Survey A Land Use Survey, conducted during 2008 around the Oyster Creek Generating Station (OCGS), was performed by Normandeau Associates, Inc. for Exelon Nuclear. The purpose of the survey was, in part, to determine the location of animals producing milk for human consumption in each of the sixteen meteorological sectors out to a distance of 5 miles from the OCGS. None were observed. Another purpose of the survey was to determine the location of gardens greater than 500 square feet in size producing broad leaf vegetation, as well as the closest residence within each of the sixteen meteorological sectors. The distance and direction of 18

all locations from the OCGS Reactor Building were determined using Global Positioning System (GPS) technology. There were no changes required to the OCGS REMP, as a result of this survey. The results of this survey are summarized below.

• Greater than 500 ft2 in size producing broad leaf vegetation E. Errata Data This section provides corrections to the 2006 and 2007 Annual Radiological Environmental Operating Reports (AREOR).

TLD data has historically been reported as mR/standard quarter in the AREOR. In the AREORs for 2006 and 2007 however, the TLD data in Tables C-VIII.1 through C-VIII.3 were inadvertently reported as mR/total exposure period, not corrected to mR/standard quarter. The corrections for this deviation involve the following sections in the 2006 and 2007 AREORs:

Appendix A - Summary Table A-1, TLD results Appendix C - TLD Table C-VIII.1 Appendix C - TLD Table C-VIII.2 Appendix C - TLD Table C-VIII.3 Appendix C - Graphs C-6 and C-7 Text - Ambient Gamma Radiation section IV.C 19

The corrected pages for the 2006 and 2007 reports are contained in Appendix E of this report.

F. Summary of Results - Inter-laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices (Appendix F). The PE samples, supplied by Analytics Inc.,

Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:

1. Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.

2. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.

The MAPEP defines three levels of performance: Acceptable (flag =

"A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value.

Performance is acceptable with warning when a mean result falls in the range from +/-20% to +/-30% of the reference value (i.e., 20% <

bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.

20

For the primary laboratory, 16 out of 18 analytes met the specified acceptance criteria. Two samples did not meet the specified acceptance criteria for the following reasons:

1. Teledyne Brown Engineering's Analytics December 2008 Sr-89 in milk result of 18.0 pCi/L was higher than the known value of 12.6 pCi/L, resulting in a found to known ratio of 1.43. NCR 09-02 was initiated to investigate this failure.

2. Teledyne Brown Engineering's Analytics' ERA Quik Response water sample January 2008 Sr-89 result of 37.33 pCi/L exceeded the upper acceptance limit of 25.2 pCi/L. No cause could be found for the failure. Studies bracketing these results, RAD 71 and RAD 72 had acceptable Sr-89 results. NCR 08-03 For the secondary laboratory, all 15 analytes met the specified acceptance criteria.

In conclusion, the Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

concentrations of strontium-89 and strontium-90 (Table C-VII.l, Appendix C). All strontium-89 results were less than the MDC. Strontium-90 was detected in eight of twenty samples. The values ranged from <2 to 124 pCi/kg wet, which is consistent with historical data.

Gamma Spectrometry Vegetation samples from locations 35, 36, and 66 were analyzed for concentrations of gamma emitting nuclides (Table'C-VII.1, Appendix C). Naturally occurring K-40 activity was found in all samples and ranged from 1,930 to 8,480 pCi/I. No Cs-137 activity was detected in any routine REMP samples. (See Section III.D.4.) All other nuclides were less than the MDC.

Preoperational vegetation sample analyses did not include strontium-89, strontium-90, or gamma spectroscopy.

In conclusion, terrestrial monitoring results for 2006 of vegetation samples, showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and Chernobyl.

The radioactivity levels detected were consistent with levels measured in past years, and no radioactivity attributable to activities at OCGS was detected in any terrestrial samples.

The terrestrial monitoring data show no adverse long-term trends in the terrestrial environment.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic Model 814 (CaSO 4 ) thermoluminescent dosimeters. Forty-nine TLD locations were monitored around the site. Results of TLD measurements are listed in Tables C-VIII.1 to C-VIII.3, Appendix C.

All TLD measurements were below 23 mR/standard quarter, with a range of 9.3 to 22.5 mR/standard quarter. 2006 gamma radiation data from the control location were plotted along with similar data from the Site, Intermediate Distance, and Outer Ring Locations (Figure C-6, Appendix C). Historical ambient gamma radiation data from the control location was plotted along with similar data from the Site, Intermediate Distance and 19 E-7

Outer Ring Locations (Figure C-7, Appendix C). In conclusion, the 2006 TLD results are proportionally consistent with preoperational and past operational measurements of direct radiation.

D. Land Use Survey A Land Use Survey, conducted during 2006 around the Oyster Creek Generating Station (OCGS), was performed by Normandeau Associates, RMC Environmental Services Division for Exelon Nuclear. The purpose of the survey was, in part, to determine the location of animals producing milk for human consumption in each of the sixteen meteorological sectors out to a distance of 5 miles from the OCGS. None were observed.

Another purpose of the survey was to determine the location of gardens greater than 500 square feet in size producing broad leaf vegetation, as well as the closest residence within each of the sixteen meteorological sectors. The distance and direction of all locations from the OCGS Reactor Building were positioned using Global Positioning System (GPS) technology. There were no changes required to the OCGS REMP, as a result of this survey. In conclusion, the results of this survey are summarized below.

Strontium-89 and Strontium-90 Vegetation samples from all locations were analyzed for concentrations of strontium-89 and strontium-90 (Table C-VII.1, Appendix C). All strontium-89 results were less than the MDC. Strontium-90 was detected in 23 of 30 samples.

The values ranged from 3 to 37 pCi/kg wet, which is consistent with historical data.

Gamma Spectrometry Vegetation samples from locations 35, 36, and 66 were analyzed for concentrations of gamma emitting nuclides (Table C-VII.1, Appendix C). Naturally occurring K-40 activity was found in all samples and ranged from 1,690 to 4,890 pCi/I. All other nuclides were less than the MDC.

Preoperational vegetation sample analyses did not include strontium-89, strontium-90, or gamma spectroscopy.

In conclusion, terrestrial monitoring results for 2007 of vegetation samples, showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and Chernobyl.

The radioactivity levels detected were consistent with levels measured in past years, and no radioactivity attributable to activities at OCGS was detected in any terrestrial samples.

The terrestrial monitoring data show no adverse long-term trends in the terrestrial environment.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic Model 814 (CaSO 4 ) thermoluminescent dosimeters. Forty-nine TLD locations were monitored around the site. Results of non-background corrected TLD measurements are listed in Tables C-VIII.1 to C-VIII.3, Appendix C.

All non-background corrected TLD measurements were below 25 mR/standard quarter, with a range of 12.6 to 24.0 mR/standard quarter.

Subtracting the appropriate background gives a range of 0 - 5.5 mR/standard quarter. No location exceeded the 40CFR190 limit of 25 mRem/year.

2007 gamma radiation data from the control location were plotted along with similar data from the Site, Intermediate Distance, and Outer Ring 17 E-15

Locations (Figure C-6, Appendix C). Historical ambient gamma radiation data from the control location was plotted along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-7, Appendix C). A review of the TLD data from 2005 through 2007, showed three step-change biases attributable to processing, two of the biases were in the positive direction (adding dose). One of these was in 2006 and one was in 2007. These account for the slightly higher doses seen in Figure C-7.

In conclusion, the 2007 TLD results are consistent with preoperational and past operational measurements of direct radiation.

D. Land Use Survey A Land Use Survey, conducted during 2007 around the Oyster Creek Generating Station (OCGS), was performed by Normandeau Associates, RMC Environmental Services Division for Exelon Nuclear. The purpose of the survey was, in part, to determine the location of animals producing milk for human consumption in each of the sixteen meteorological sectors out to a distance of 5 miles from the OCGS. None were observed.

Another purpose of the survey was to determine the location of gardens greater than 500 square feet in size producing broad leaf vegetation, as well as the closest residence within each of the sixteen meteorological sectors. The distance and direction of all locations from the OCGS Reactor Building were positioned using Global Positioning System (GPS) technology. There were no changes required to the OCGS REMP, as a result of this survey. The results of this survey are summarized below.

Summary and Conclusions This report on the Radiological Groundwater Protection Program (RGPP) conducted for the Oyster Creek Generating Station (OCGS) by Exelon covers the period 01 January 2008 through 31 December 2008.

In 2006, Exelon instituted a comprehensive program to evaluate the impact of station operations on groundwater and surface water in the vicinity of the Oyster Creek Generating Station. This evaluation involved numerous station personnel and contractor support personnel.

This is the second in a series of annual reports on the status of the Radiological Groundwater Protection Program (RGPP) conducted at the Oyster Creek Generating Station. This report covers groundwater and surface water samples collected from the environment, both on and off station property in 2008. One hundred and sixty-seven (167) analyses were performed on 81 samples from 35 locations.

Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) as specified in the Offsite Dose Calculation Manual (ODCM) in any of the groundwater or surface water samples. In the case of tritium, Exelon specified that its laboratories achieve a lower limit of detection 100 times lower than the drinking water limit specified by the United States Environmental Protection Agency (USEPA) (200 pCi/liter versus 20,000 pCi/liter).

Tritium was not detected in groundwater or surface water samples at concentrations above the LLD of 200 pCi/liter. These results are consistent with historical background tritium levels in surface water and groundwater at the OCGS.

Strontium-90 was not detected in any groundwater or surface water sample during 2008.

In assessing all the data gathered for this report, it was concluded that the operation of the Oyster Creek Generating Station had no adverse radiological impact on the environment, and there are no known active releases into the groundwater or surface water at the Oyster Creek Generating Station.

II. Introduction The Oyster Creek Generating Station (OCGS), consisting of one boiling water reactor owned and operated by Exelon, is located on the Atlantic Coastal Plain Physiographic Province in Ocean County, New Jersey, about 60 miles south of Newark, 9 miles south of Toms River, and 35 miles north of Atlantic City. It lies approximately 2 miles inland from Barnegat Bay. The site, covering approximately 781 acres, is situated partly in Lacey Township and, to a lesser extent, in Ocean Township. Access is provided by U.S. Route 9, passing through the site and separating a 637-acre eastern portion from the balance of the property west of the highway. The station is about 11/4 mile west of the highway and 11/4 'miles east of the Garden State Parkway. The site property extends about 21/2 miles inland from the bay; the maximum width in the north-south direction is almost 1 mile. The site location is part of the New Jersey shore area with its relatively flat topography and extensive freshwater and saltwater marshlands. The South Branch of Forked River runs across the northern side of the site and Oyster Creek partly borders the southern side.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. (Midwest Labs) on samples collected in 2008.

A. Objectives of the RGPP The long-term objectives of the RGPP are as follows:

1. Identify suitable locations to monitor and evaluate potential impacts from station operations before significant radiological impact to the environment and potential drinking water sources.

2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up-to-date knowledge of flow patterns on the surface and shallow subsurface.

3. Perform routine water sampling and radiological analysis of water from selected locations.

4. Report new leaks, spills, or other detections with potential radiological significance to stakeholders in a timely manner.

5. Regularly assess analytical results to identify adverse trends.

6. Take necessary corrective actions to protect groundwater resources.

B. Implementation of the Objectives The objectives identified have been implemented at the Oyster Creek Generating Station as discussed below:

1. Exelon and its consultant identified locations as described in the Phase 1 study. Phase 1 studies were conducted by Connestoga Rovers and Associates (CRA) and the results and conclusions were made available to state and federal regulators as well as the public on an Exelon web site in station specific reports.

http://www.exeloncorp.com/ourcompanies/powergen/nuclear/Tritiu m.htm

2. The Oyster Creek Generating Station report describes the local hydrogeologic regime. Periodically, the groundwater flow patterns are updated based on ongoing measurements.

3. The Oyster Creek Generating Station will continue to perform routine sampling and radiological analysis of water from selected locations.

4. The Oyster Creek Generating Station has implemented new procedures to identify and report new leaks, spills, or other detections with potential radiological significance in a timely manner.

5. The Oyster Creek Generating Station staff and independent consultants, including a hydrogeologist, assess analytical results on an ongoing basis to identify adverse trends.

C. Program Description Samples for the OCGS site were collected for Exelon by on-site personnel and Normandeau Associates, Inc. This section describes the general collection methods used to obtain environmental samples for the OCGS RGPP in 2008. Sample locations can be found in Table A-i, Appendix A.

1. Sample Collection Groundwater and Surface Water Samples of water are collected, managed, transported and analyzed in accordance with approved procedures following EPA methods. Both groundwater and surface water are collected.

Sample locations, sample collection frequencies and analytical frequencies are controlled in accordance with approved station procedures. Contractor and/or station personnel are trained in the collection, preservation management, and shipment of samples, as well as in documentation of sampling events. Analytical laboratories are subject to internal quality assurance programs and industry cross-check programs, as well as nuclear industry audits.

Station personnel review and evaluate all analytical data deliverables as data are received.

Analytical data results are reviewed by both station personnel and independent consultants, including a hydrogeologist, for adverse trends or changes to hydrogeologic conditions.

D. Characteristics of Tritium (H-3)

Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called "tritiated water." The chemical properties of tritium are essentially those of ordinary hydrogen.

Tritiated water behaves the same as ordinary water in both the environment and the body. Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through the skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Tritium is excreted primarily through urine with a clearance rate characterized by an effective biological half-life of about 14 days. Within one month or so after ingestion, essentially all tritium is cleared. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period. Tritium atoms can exchange with any hydrogen atom. If the hydrogen atom is part of an organic molecule, the tritium becomes 'organically bound' and is transported with the molecule rather than moving freely like water.

Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotopes lithium-7 and/or boron-10 are activated to produce tritium. Also, tritium was released into the atmosphere from Chernobyl in 1986. Like normal water, tritiated water is colorless and odorless. Tritiated water behaves chemically and physically like non-tritiated water in the subsurface, and therefore tritiated water will travel at the same velocity as the average groundwater velocity.

Tritium has a half-life of approximately 12.3 years. It decays spontaneously to helium-3 (He-3). This radioactive decay releases a beta particle (18.6 keV low-energy electron). The radioactive decay of tritium is the source of the health risk from exposure to tritium. Tritium is one of the least dangerous radionuclides because it emits very weak radiation and leaves the body relatively quickly. Since tritium is almost always found as water, it goes directly into soft tissues and organs. The associated dose to these tissues is generally uniform and is dependent on the water content of the specific tissue.

Ill. Program Description A. Sample Analysis This section describes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the Oyster Creek Generating Station RGPP in 2008.

In order to achieve the stated objectives, the current program includes the following analyses:

1. Biennial concentrations of gamma emitters in groundwater and surface water.

2. Biennial concentrations of strontium-90 in groundwater and surface water.

3. Semi-annual concentrations of tritium in groundwater and surface water.

B. Data Interpretation The radiological data collected prior to Oyster Creek Generating Station becoming operational, as well as background data from publicly available databases, were used as a baseline with which these operational data were compared. For the purpose of this report, Oyster Creek Generating Station was considered operational at initial criticality. Several factors were important in the interpretation of the data:

1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD is intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criterion for the presence of activity. All analyses were designed to achieve the required OCGS detection capabilities for environmental sample analysis.

The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2. Laboratory Measurements Uncertainty The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the measurement value.

Statistically, the exact value of a measurement is expressed as a range with a stated level of confidence. The convention is to report results with a 95% level of confidence. The uncertainty comes from calibration standards, sample volume or weight measurements, sampling uncertainty and other factors. Exelon reports the uncertainty of a measurement created by statistical process (counting error) as well as all sources of error (Total Propagated Uncertainty or TPU). Each result has two values calculated.

Exelon reports the TPU by following the result with plus or minus

(+/-) the estimated sample standard deviation, as TPU, that is obtained by propagating all sources of analytical uncertainty in measurements.

Analytical uncertainties are reported at the 95% confidence level in this report for reporting consistency with the AREOR.

C. Background Analysis A pre-operational radiological environmental monitoring program (pre-operational REMP) was conducted to establish background radioactivity levels prior to operation of the station. The environmental media sampled and analyzed during the pre-operational REMP were atmospheric radiation, fall-out, domestic water, surface water, marine life, and foodstuffs. The results of the monitoring were detailed in the report entitled, Pre-Operational Environmental Radiation Survey, Oyster Creek Nuclear Electric Generating Station, Jersey Central Power & Light Company, dated March 1968.

This report contains analytical results from samples collected from both surface water and groundwater.

Monthly surface water sampling began in 1966, and the samples were analyzed for tritium as well as other radioactivity. During the preoperational program, tritium was detected at an average concentration of 1.05E+3 pCi/liter, indicating that these preoperational results were from nuclear weapons testing and are radioactively decaying as predicted. At that time, counting instrumentation was not as sensitive as it is now, and the minimum detectable concentration was 1E+3 pCi/liter versus 2E+2 pCi/liter used today. Gamma isotopic and radio strontium analyses results average concentrations were all greater than radioisotope analyses results from operational data.

1. Background Concentrations of Tritium The purpose of the following discussion is to summarize background measurements of tritium in various media performed by others. Additional detail may be found by consulting references.

a. Tritium Production Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man-made) sources. In the upper atmosphere, "cosmogenic" tritium is produced from the bombardment of stable nuclides and combines with oxygen to form tritiated water, which will then enter the hydrologic cycle. Below ground, "lithogenic" tritium is produced by the bombardment of natural lithium present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant uranium and thorium. Lithogenic production of tritium is usually negligible compared to other sources due to the limited abundance of lithium in rock. The lithogenic tritium is introduced directly to groundwater.

A major anthropogenic source of tritium and strontium-90 comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased significantly during the 1950s and early 1960s, and later with additional testing, resulting in the release of significant amounts of tritium to the atmosphere. The Canadian heavy water nuclear power reactors, other commercial power reactors, nuclear research and weapons production continue to influence tritium concentrations in the environment. Also, tritium was released into the atmosphere from Chernobyl in 1986.

b. Precipitation Data Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides. Two publicly available databases that provide tritium concentrations in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet database. GNIP provides tritium precipitation concentration data for samples collected world wide from 1960 to 2006.

RadNet provides tritium precipitation concentration data for samples collected at stations throughout the U.S. from 1960 up to and including 2006. Based on GNIP data for sample stations located in the U.S. Midwest, tritium concentrations peaked around 1963. This peak, which approached 10,000 pCi/liter for some stations, coincided with the atmospheric testing of thermonuclear weapons. Tritium concentrations in surface water showed a sharp decline up until 1975 followed by a gradual decline since that time. Tritium concentrations in precipitation in New Jersey have typically been below 100 pCi/liter since around 1980. Tritium concentrations in wells may still be above the 200 pCi/liter detection limit from the external causes described above. Water from previous years and decades is naturally captured in groundwater, so some well water sources today are affected by the surface water from the 1960s that was elevated in tritium.

c. Surface Water Data Tritium concentrations are routinely measured in large surface water bodies, including Forked River and Barnegat Bay. New Jersey surface water data were typically less than 100 pCi/liter.

The USEPA RadNet surface water data typically has a reported 'Combined Standard Uncertainty' of 35 to 50 pCi/liter. According to USEPA, this corresponds to a +/-70 to 100 pCi/liter 95% confidence bound on each given measurement. Therefore, the typical background data provided may be subject to measurement uncertainty of approximately +/- 70 to 100 pCi/liter.

The radio-analytical laboratory is counting tritium results to an Exelon specified LLD of 200 pCi/liter. Typically, the lowest positive measurement will be reported within a range of 40 - 240 pCi/liter or 140 +/- 100 pCi/liter. Clearly, these sample results cannot be distinguished as different from background at this concentration.

IV. Results and Discussion Gamma spectroscopy results for each type of sample were grouped as follows:

For groundwater and surface water 14 nuclides, Be-7, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, 1-131, Cs-134, Cs-137, Ba-140 and La-140 were reported.

A. Groundwater Results Samples were collected from on-site wells in May, September and October in accordance with the station radiological groundwater protection program. In addition to the wells sampled during 2007, a groundwater sample was also obtained from lysimeter CST-9, located near the Station's main condenser discharge, during the fall 2008 sampling event. As reported in CRA's 2006 Hydrogeologic Investigation Report and previous groundwater investigations at the Station, groundwater flow in the vicinity of the Torus Water Storage Tank and the-Condensate Storage Tank is towards the intake and discharge structures. Groundwater accumulating in the vicinity of the intake and discharge structures is directed into the discharge canal via a system of gravel drains installed during Station construction. Lysimeter CST-9 is positioned to intercept this flow.

Due to the limited amount of water available from this lysimeter, the sample was only analyzed for tritium. Analytical results and anomalies are discussed below.

Tritium Samples from 31 locations were analyzed for tritium activity (Table B-1.1 Appendix B). Tritium was not detected at a level above the LLD of 200 pCI/liter.

Strontium Strontium-90 was not detected in any location sampled in 2008.

Gamma Emitters No gamma emitting nuclides, other than naturally occurring potassium-40, were detected in any of the samples analyzed during 2008. (Table B-1.2, Appendix B).

B. Surface Water Results Samples were collected from on-site locations in May, September and October in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.

Tritium Samples from three locations were analyzed for tritium activity (Table B-11.1, Appendix B). Tritium was not detected at a level above the LLD of 200 pCI/liter.

Strontium Strontium-90 was not detected in any location sampled in 2008.

Gamma Emitters No gamma emitting nuclides, other than naturally occurring potassium-40, were detected in any of the samples analyzed.

(Table B-11.2, Appendix B).

C. Drinking Water Well Survey A drinking water well survey was conducted during the summer of 2006 by CRA (CRA 2006) around the Oyster Creek Generating Station. CRA reviewed the New Jersey Geological Survey Bureau of Water Allocation Database Search included in the report entitled "Remedial Action Work Plan - Non-Radiological GPU Nuclear, Inc.; Oyster Creek Nuclear Generating Station U.S. Route 9 Forked River New Jersey" (URS GWC, 2000). The database provides a list of permitted wells within a 5-mile radius of the station and includes private, public, and industrial water supply wells and monitoring wells. The database indicates no public water supply well permits exist within a 0.5-mile radius of the center of the station (i.e., Reactor Building).

In addition to the two domestic water supply wells located on the OCGS site, the database indicated that there were three individually owned locations permitted for a water supply well within a 0.5-mile radius of the station.

In addition to the water supply wells identified in the database, there are seven wells located on the property to the west of the station (i.e.,

combustion turbine facility). These seven wells supply water for fire protection (4 wells), process water for the combustion turbine system (2 wells) and one domestic water supply well.

D. Summary of Results - Inter-Laboratory Comparison Program Inter-Laboratory Comparison Program results for TBE and Environmental Inc. (Midwest Labs) are presented in the 2008 Oyster Creek AREOR.

E. Leaks, Spills, and Releases The OCGS records inadvertent releases of radioactive liquids in accordance with 10 CFR 50.75(g). As part of the hydrogeologic investigation associated with Exelon's fleet wide assessment in 2006, a third party environmental engineering firm was contracted to evaluate historic releases, if any, and determine if a potential pathway to the environment existed. Those releases that were determined to have potentially impacted groundwater were subsequently investigated as part of the fleet wide assessment. The hydrogeologic investigation determined that there were no radiological impacts to groundwater at the Oyster Creek Generating Station.

There were no inadvertent radiological leaks, spills, or releases during 2008, other than one actuation of the Isolation Condensers. The Isolation Condensers were actuated during a reactor scram on November 28, 2008, resulting in a ground-level release of approximately 4.57 microcuries of tritium. Based upon the results of historical groundwater monitoring at the OCGS, this release is not expected to have any impact on groundwater quality.

F. Trends No trends have been identified.
