Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP) conducted for the Oyster Creek Generating Station (OCGS) by Exelon Nuclear covers the period 01 January 2011 through 31 December 2011. During that time period, 1622 analyses were performed on 1244 samples. In assessing all the data gathered -forthis report and comparing these results with historical data, it-was concluded that the operation of OCGS had no adverse radiological Impact on the envi nment On March 11,2011 an earthquake off the Japanese islands produced a massive tsunami that caused a nuclear accident at four of the six Fukushima Dailichi reactors. In planning for the potential radioactive plume reaching the United States, Exelon Nuclear increased the sampling frequency and added additional analyses of select media from pathways that were expected to be the most sensitive to any Increase in ambient radiation levels. Low level 1-131 analyses and gamma spectroscopy analyses were performed on air particulates, air Iodine, and milk, as appropriate.

The resulting radioactive plume was first detected in the environs of Oyster Creek Generating Station on March 16, 2011. The final date of positive detection was April 13, 2011. The radionuclide identified was Iodine-1 31.

Maxdmum activity levels found by media were 64 E-3 pCI/m 3 for air iodine.

Samples collected were compared to offsite control locations to verify that these positive detections were not attributable to licensed activities. All other radionuclides analyzed for were below MDC (Minimum Detectable Concentration).

The radioactive half-life of 1-131 Is about 8 days. This short half-life allowed the affects of this radioactive plume to subside over about 4 weeks. As of April 14, 2011 no further impacts from the Fukushima Daiichi accident was evident.

REMP designated surface water samples were analyzed for concentrations of tritium and gamma emitting nucides. No tritium and no fission or activation products were detected in any of the surface water samples collected as part of the Radiological Environmental Monitoring Program during 2011.

REMP designated drinking water samples were analyzed for concentrations of gross beta, tritium, 1-131, and gamma emitting nuclides. The preoperational environmental monitoring program did not include analysis of drinking water for gross beta. No tritium, 1-131, or fission or activation products were detected In any of the drinking water samples collected.

REMP designated groundwater samples were analyzed for concentrations of tritium and gamma emitting nuclides. No tritium and no fission or activation products were detected in REMP groundwater samples.

Fish (predator and bottom feeder), dams, crabs, and sediment samples were analyzed for concentrations of gamma emitting nuclides. No OCGS-produced 1

fission or activation products were detected in fish, clams and crabs.

Cesium-1 37 was not detected in any sediment samples.

Air particulate samples were analyzed for ntrations of gross beta, gamma emitting nuclides, Strontium-89, and Strontium-90. Gross beta and cosmogenic Be-7 was detected at levels consistent with those detected in previous years. No

-fission or activation products were'deteced. Strontium-89 and Strontium-90 analyses were performed on quadrbe*l composites of air particulate samples. All Strontium489 and Strontium-90 results w below the minimum detectable activity. -

High sensitivity 1-131 analyses were performed on weeldy air samples. All results were less than the minimum. detectable concentration with the exception of 24 samples which were positive for 1-131. These positive results are directly attributed to the Fukushima event in March of 2011.

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 historicalnuclear weapons testing and the Chemobyl accident."

Environmental gamma radiatiqn measurements were performed quarterly using thermolurminescent dosimeters. The maximum dose to any member of the public attributable to radioactive effluents and direct radiation from the OCGS was less than the 25 mreo/year limit established by the United States Environmental Protection Agency (EPA).

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 froi Bamegat Bay. The site, covering approximately 781 acres, is situad party 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 % mile west of the highway and 1% miles east of the Garden State Parkway. The site property extends about 2% miles inland from the bay; the maximum width in the north-south direction is almost I 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), Midon Technologies, and Environmental Inc. (Midwest Labs) on samples coll1cted during the period 01 January 2011 through 31 December2011.

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).

3

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

1. Identifying signilcant 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. 1This 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, theoperational surveillance program

ýcontinued to measure radiation and radioactivity in the surrounding areas.

A variety of environmental samples are collected as part of the REMP at 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 halflives, 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 4

operation begins. Radiochemical analyses performed on the environmental samples should include not only those nuclides expected to be released during facility operation, but should also include typical radionucides 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 radloanalyses 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 environmenL 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 PlantEffluents 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 the people or the environment surrounding OCGS and is well below the applicable levels set by the Nuclear Regulatory

• 5

Commission (NRC) and the EPA.

There were liquid radioactive effluent releases during 2011 of concentrations of tritium too, low, to detect at an LLD of 200 picocudes per liter (pCI/L) at the NJPDES permitted main condenser outfall., The: releases, were part. of nearly continuous pumping of groundwater at, approximately..70 gpm containing low levels of tritium and. no detectable gamma.. Exelon and the State of New Jersey.. Department of, Environmental Protection (NJDEP) agreed to this remediation action after a period of natural attenuation to address concentrations of tritMum in groundwater.

Well 73 and supporting equipment and piping were installed to pump groundwater to the Intake structure at the inlet of the main circulating water pumps. Provisions were established for both batch and continuous releases of groundwater. There was one batch release in August of 2011 and nearly continuous releases for the entire year of 2011. Nearly continuous releases occurred from January 1, 2011 through December 31, 2011 with a total of 3.28E+07 gallons of groundwater pumped resulting, in 9.63E-01 Ci of tMitlum released to the discharge canal. The dose to the most limiting member of.,the public due to the release of groundwater was 4.59E-06 mrem.

.;'...Utilizing gaseous effluent data, the maximum hypothetical dose to any individual In the southeast sector of the plant (sector of predominant wind direction) during 2011 was calculted 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 hypotheticalcalculated.organ dose (Bone) from iodines and particulates to any individual due to gaseous effluents was 4.42E-01mrem (0.42mrem) which was approximately 3.14 percent of the annual limit. The maximum hypothetical calculated whole body dose to any individual due to noble. gas effluents was 3.46E-03 mrem (0.00346.mrem)-which was 6.92E-04 percent of the annual limit.

The total maximum hypothetical organ dose (Bone) due to all radiological effluents of 4.42E-01 mrem (0.442 mrem) received by any individual from gaseous effluents from the Oyster Creek Generating Station for the reporting period is more than 678 times lower than the dose the average individual in the Oyster Creek area received from background radiation, including that from radon, 6

during the same lime 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 2011, the maximum direct radiation dose to the most likely exposed MEMBER OF THE' PUBLIC potentially attributable to the operation of Oyster Creek beyond the site boundary In the southeast sector, as shown by offsite thermoluminescent dosimeter

("LD) readings at stations 66, 109 and 11, was less than the dose at the control locations.

Environmental sampling of airborne iodine and particulates showed no radioactivity attributable to the operation of OCGS.

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%2011. Sample locations and descriptions can be found in Tables B-I and B-2, and Figures B-I, B-2, and B-3, Appendix B. The collection procedures are listed in Table B-3.

Aauatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, groundwater, 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), monthly from six drinking water wells (IN, IS, 37, 38, 39, and 114) and quarterly from 2 groundwater stations (MW-24;-3A and W-3C). 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, ware collected semiannually at three locations (33, 93 and 94 (control)). Clams were collected semiannually from three locations (23, 24, and 94 (control)). Two annual crab samples were collected from two locations (33 and 93). Sediment samples were collected at four locations semiannually (23, 24, 33, and 94 (control)).

7

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 11). 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.

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 four locations (35, 36, 66, and 115). Station 36 was the control location. All samples werevcollected 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 (CaSO4 )lthermoluminescent dosimeters (TLD). The TLDs were placed on and around the OCGS site and were categorized as follows:

A site boundary rina consisting of 19 locations (1, TI, 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..

SDecial 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.

8

Backaround (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. TIDs were also placed in each meteorological sector in the I 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 CaSO 4 thermoluminescent 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 Mirion Technologies 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 theOCGS REMP in 2011. 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 and drinking water.

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

3. Concentrations of tritium in REMP designated surface, drinking water and groundwater.

4. Concentrations of 1-131 In air iodine cartridges and drinking water.

5. Concentrations of strontium In air particulates and vegetation.

6. Ambient gamma radiation levels at various locations around the OCGS, 9

C. Date Interpretation For trending purposes, the radiological and direct radiation data collected during 2011 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 ofOCGS continues to have no measurable radiological impact upon the environment.

Several factors were important in the interpretation of the data:

I. Lower Limit of DQtection 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 "rear 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 thepresence of activity.

2. Net Activity Calculation and Reoortina 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, drinking water, and groundwater 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, 10

Cs-134, and Cs-137 were reported.

For clams eight nucides: K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-i 34. and Cs-I 37 were reported.

For crabs eight nuclides: K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-134, and Cs-I37were reported.

For sediment seven nuclides: Be-7, K-40, Mn-54, Co-58, Co-60, Cs-134, and Cs-137Twere reported.

For air particulate six nuclides: Be-.7, Mn-54, Co-58, Co-60, Cs-I 34, and Cs-I 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-I 37, 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 2011 the OCGS REMP had a sample recovery rate in excess of 99%.

Exceptions are listed below.

1. January 5, 2011, air particulate/air iodine stations 3 and 20 were analyzed as 14 days samples instead of normal weekly sampling due to a snow storm the previous week preventing filter change.

2.: Drinking water station 39 (Lacey Twp., MUA Pump Station) was not collected January.1, 2011. through April 6, 2011. The station was off line for this period of time.

3. Week of April 24, 2011, One TLD from Station 63 was missing and one TLD from Station 99 was missing.

4. Week of July 17, 2011, no samples were collected at vegetation station 66. Crops were too small and even- a collection of the minimum amount required by the lab would have not allowed any crops for later in the season.

5. Starting with the July 2011 drinking water composite sample, the II

station changed the LLD for 1-131 from 15 pCi/I to 1 pCi/I for REMP drinking water samples. The July drinking water composites had been collected when the vendor lab was notified to make this change. The change in LLD for 1-131 requires a different analysis to be performed which uses more sample to obtain the lower LLD.

The vendor used the entire sample for two out of the five drinking water sample locations prior to performing gross beta analysis. This resulted in gross beta not being performed for sample locations IN and IS forthe month of July.

6. Week of August 14, 2011, vegetation station 66, samples less than 1000 grams were collected because the plants were small and to collect the full amount would not have allowed samples for the next month. Enough mass was collected to complete the required analysis.

7. Week of August 28, 2011, air particulate/air iodine stations 71, 73, 66 and C all had shorter run times than usual. The stations are believed to have lost power for some time during hurricane Irene.

All of the samples were valid and sent to the lab for analysis.

8. Week of August 28, 2011, drinking water station 39 (Lacey Twp.,

MUA Pump Station) was out of service due to hurricane Irene.

9. September 7, 2011, air particulate/air iodine station 20 vacuum pump was not running during the time of collection. Sample pump was replaced and verified to be functional. All of the samples were valid and sent to the lab for analysis.

10." Week of September 11-0 2011, only one species of vegetation was collected at Station 66. There were no other samples collected at this-garden due to crop failure, most likely due to too much rain.

This was the last sample at this location for the year. Only two species were collected at Stations 35 and 115., The cabbage was done at both locations.

11. September 22, 2011, the pump at air particulate/air iodine station C was changed out because the vacuum gauge was reading low.

12. Drinking water station 38 (Ocean Township MUA Pumping Station) was not collected October 27, 2011 through December 31, 2011.

The station was off line for this time period.

13. The December 2011 Drinking water composite for sample location IN was only two weeks due to the IN location being out of service 12

for upgrades between December 18, 2011 and December 31, 2011. Due to insufficient sample volume, the 1-131 (Low Level) analysis was not performed.

• NOTE: Per the Oyster Creek ODCM, if garden vegetation samples are unobtainable due to any legitimate mason, 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 Starting in July, 1-131 is now being analyzed in drinking water by the low level method to detect down to 1 pCi/L.

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:

Tritium Samples from all locations were analyzed for tritium activity (Table C-1.1, Appendix C). No tiltium 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 13

nuclides (Table C-l.2, Appendix C). All nuclides were less than the MDC.

Surface water sampling began in 1966, and the samples were analyzed for tMltum 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 1.E+3 pCi/liter versus 2E+2 pCi/iter used today. By comparing the 2011 sampling results to the decay corrected average preoperational concentration reported in the 2007 Annual Radiological Environmental Operating Report (1.11 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 testing and Chemobyl, and is decreasing with time.

2. Drinking water Monthly samples were composited from monthly grab samples from six drinking water wells (IN, 1S, 37, 38,39, and 114). Station 1, because it Is located on the OCGS site, could potentially be affected by radioactive releases from the plant Station I was split into two separate locations, IN and IS. 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:

Monthly samples from all locations were analyzed for tritium activity (Table C-41.1, Appendix C). No tMtum activity was detected.

Drinking water was sampled during the preoperational program and throughout the 42 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.

2011 results are all less than the current MDC of 200 pCi/liter.

14

Monthly samples from all locations were analyzed for concentrations of total gross beta activity (Tables C-11.2, Appendix C). Gross beta was detected In 34 of 65 samples, and is expected due to natural sources and fallout residual from, previous bomb testing. The vaeues rangedfrom 1.8 to 5.4pClil. The investigation level for gross beta;:iný water is 15 pCi/I. Gross beta was detected at about the same concentration in both control and sample locations.

Iodine, Starting in July, monthly samples from all locations were analyzed for 1-131 by the low level method to detect down to I pCi/L (Table C-11.3, Appendix C). All results were less than the MDC.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nudides (Table C-41.3, Appendix C). All nucides were less than the MDC.

S3. Groundwater The following analyses-were performed:

ndbum Samples from all locations were analyzed for tritium activity (Table C-411.1, Appendix 0). No trttiurh:activity was detected.

Gamma Spectrometrv Samples from both locations were analyzed for gamma emitting nuclides (Table 0-411.2, Appendix C). All nucides were less than the MDC.

.4. Fish Fish samples comprised of bottom feeder (winter flounder, summer flounder, and.tautog) and predator (American eel, jack, sea trout, striped bass, sea bass, bluefish, tigger fish, and white perch) 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:

15

Gamma Suectrometrv The edible portions of fish samples from three locations were analyzed for gamma emitting nudides (Table C-NV. 1, Appendix C).

Naturally occurring potassium-40 was found at all stations and ranged from 2,440 to, 5,440 pCIkg 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.

5. Clams and Crabs Clams were collected at three locations (23, 24, and 94) semiannually. Crabs were collected at two. locations (33 and 93)

.annually. Locations 23, 24, 33, and 93 could be affected by Oyster Creek's effluent releases. The following analysis was performed:

Gamma SDectrometry-The edible portions of dam'samples from all three locations were analyzed forgamma emitting nudides (Table C-IV.2, Appendix C).

Naturally occurring potassium-40 was found at all stations and ranged from 1,250 to 1,,940 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 dams are shown in Figure C-1, Appendix C.

Preoperational clam sample'resultsfor 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 two locations were analyzed for gamma emitting nuclides (Table C-lV.2, Appendix C).

Naturally occurring potassium-40 was found at both stations and ranged from 2,270 to 3,220 pCi/kg wet andwas 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.

16

6. 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 Soectrometrv Sediment samples from all four locations were :analyzed for gamma emitting nuclides (Table C-V.1, Appendix C).

Potassium-40 was found at all stations and ranged from 1,170 to 15,400 pCi/kg dry. Ceslum-137 was not detected in any of the samples. No fission or activation products were found. Figure C-3, Appendix C graphs Cs-I37 concentrations in sediment from 1984 through 2011 and figure C-2, Appendix C graphs Co-60 concentrations in sediment from 1984 through 2011.

The requirement for sampling sediment is a requirement of ODCM 3.12.1, Table 3.12.1-1.d. ODCM Table 3.12.1-2, Reporting Levels for Radioactive Concentrations Jn Environmental samples Reporting Levels does not include requirements for sediment.

CY-AA-170-1000, Radiological Environmental Monitoring Program and Meteorological Program Implementatio, ,Attachment 1, Analytical Results Investigation Levels, includes sediment investigation level for:Cs-137,of 1000 pCi/kg, dry.

While aquatic sediment sampling was part of the preoperational program, samples were not analyzed for gamma emitting nuclides until 1981..

In conclusion, the 2011 aquatic monitoring results for surface water, drinking water, fish, dams and crabs 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 radloactivity attributable to activities at OCGS was detected in any aquatic samples during 2011 and no adverse long-term trends are shown in the aquatic monitoring data.

17

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 andý locations at a remote distance from OCGS (C and 3). The following analyses were performed:

Gross Beta.

Weekly samplesmwere analyzed for concentrations of beta emitters (Table C-VI.1 and C-VI,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 7 to 31 E-3 pCiUm 3 with a mean of 16 E-3 pCi/m 3 . The results from the Intermediate Distance locations (Group II)mrae from 5 to 33 E-3 pCi/m 3 with a mean of 16 E-3 pCi/mn. The results from the Distant locations (Group Ill) ranged from 6 to 30 E-3 pCi/m 3 with a mean of 15 E-3 pCi/m°. 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).:

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/m3. 2011 gross beta activity values ranged from <6E-3 to 33E-3 pCi/m3. The 2011 results are consistent with historical operational data (Figure C-5, Appendix C) and fall within the range of results observed during the preoperational period.

18

Strontium-89 and Strontium-90 Weekly samples were composited quarterly and analyzed for strontdum-89 and strontium-90 (Table C-VI.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 analysisof air samples for strontlum-89 and strontium-90.

• *Gamma Spectrometr Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-VIA, Appendix C).

Naturally occurnng Be-7 due to cosmic ray activity was detected In all samples. The values ranged from 37 to 96 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 nudides.; Additional sampling occurred in the weeks immediately following the Fukushima event in 2011. All nuclides were less than the MDC.

b. Airborne lodine. .

Continuous air samples were collected from eight (C, 3, 20, 66, 71, 72, 73, 111) locations and analyzed weekly for 1-131 (Table C-VII.1, Appendix C).ý Consistent with historical operational data, all results were less than the MDC, with the exception of 24 samples which were positive for 1-131.

These positive results are directly attributed to the Fukushima event in March of 2011.

The preoperational environmental monitoring program for OCGS did not Include analysis of air media for iodine-131.

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 the operation of OCGS.

19

2. Terrestrial

a. Vegetation Samples were collected from four locations (35, 36, 66, and 115) 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-VIII.1, Appendix C). All strontium-89 results were less than the MDC. Strontium-90 was detected in 15 of 36 samples.

The values ranged from 2.7 to 12.0 pCVkg wet, which is consistent with historical data.

Gamma Soectrometrv Vegetation samples from locations 35, 36, 66, and 115 were analyzed for concentrations of gamma emitting nuclides (Table C-VIII.1, Appendix C). Naturally occurring K-40 activity was found in all samples~and ranged from 2,120 to 7,070 pCI/kg wet. Naturally occurring Be-7 was detected in 21 of 36 samples and ranged from 89 to 1,110 pCi/kg wet.

These results are consistent with historical operational data.

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 2011 showed only naturally occurring radloactivity and radioactivity associated with fallout from

• past t* atmospheric nuclear weapons testing and Chemobyl.

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 (CaSO4) thermoluminescent dosimeters. Sixty-one TLD locations were monitored around the site. Results of non-background 20

corrected no.measurements are summarized in Tables C-IX.1 to C-IX.3 and Figures C-6 and C-7.

The non-background corrected TLD measurements ranged from 9.0 to 25.2 mR/standard quarter. Inr 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 18.2 mR/year at Station 55, locatednear the site boundary, 0.3 miles west of the OCGS. This TLO 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 inone of the four quarterly monitoring periods during 2011.

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 2011 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 in August 2011 around the Oyster Creek Generating Station (OCGS), was performed by Normandeau Associates, Inc. for Exelon Nuclear. The purpose of the survey is to identify within a distance of 5 miles the location in each of the 16 meteorological sectors of the nearest milk animal, the nearest residence and the nearest garden of greater than 500 ft2 producing broad leaf vegetation. The census shall also identify within a distance of 3 miles the location in each of the 16 meteorological sectors all milk animal and all gardens greater than 500 square feet producing broadleaf vegetation. For 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. The distance and direction of 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.

Summary of Results - Inter-laboratory Comparison Program Theiprimary and seco*da 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 OC requirements, which are based on the DOE MAPEP criteria.

2. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and limitswarning.limits withper are established associated the USEPA, flag NELAC, values. state ERA'sspecific acceptance PT program requirements or ERA's SOP for the Generation of Performance Acceptance Umits, as applicable. The acceptance 22

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 = W"), Acceptable with-Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is 1 20% of the reference value. Performance is acceptable with warning when a mean result falls In the range from +/-20% to 030% of the reference value (i.e., 20% < bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.

For the primary laboratory, 14 out of 18 analytes met the specified acceptance criteria. Four analytes did not meet the specified acceptance criteria for thefollowing reason:

1. Teledyne Brown Engineering's Analytics March 2011 Cr-51 in milk result of 398 pCI/L was. higher than the known value of 298 pCi/L.,

resulting in a found. t known rati0oof 1.34., NCR 1113 - was initiated to.investigate this failure. There was a slightly high bias in all the gamma activities. 4'The June gamma results in milk did not show a high bias. No fu~rt

• action w required.

2. Teledyne Brown Engineering's ERA May 2011 Gross Alpha in water result of 64.1 pCi/L was higher than the known value of 50.1 pCi/L, which exceeded the upper control limit of 62.9 pCi/L. NCR 11-08 was initiated to investigate this failure. The solids on the planchet exceeded 100 mg, which was beyond the range of the efficiency curve.

Teledyne Brown Engineering's MAPEP March 2011 Gross Alpha in air particulate result of 0.101 Bq/sample was lower than the known value of 0.659 Bq/sample, which exceeded the lower control limit of 0.198 Bq/sample. NCR 11-11 was initiated to investigate this failure. The air partdiulate filter was counted on the wrong side.

3. Teledyne Brown Engineering's ERA November 2011 Sr-89 in water result of 81.0 pCiL, was higher than the known value of 69.7 pCi/L, which exceeded the upper control. limit of 77.9 pCi/L. NCR 11-16 was initiated to investigate this failure. The TBE reported value to 23

known ratio of 1.16 fell within the acceptable range of + 20%, which TBE considers acceptable.

4. Teledyne Brown Engineering's MAPEP March 2011 Sr-90 in soil, air particulate and vegetation were non-reports that were evaluated as failed. NCR 11-11 was initiated to investigate these failures.

MAPEP evaluated the non-reports as failed due to not reporting a previously reported analyte.

For the secondary laboratory, Environmental, Inc., 11 out of 14 analytes met the specified acceptance criteria.

1. Environmental Inc.'s ERA October 2011 Cs-134 in water result of 38.8 pCi/L was higher than the known value of 33.4 pCiIL, which exceeded the upper control limit of 36.7 pCi/L. The sample was reanalyzed. The reanalyzed result of 32.9 was acceptable.

2. Environmental Inc.'s MAPEP February 2011 Sr-90 in air particulate result of 1.89 Bqlsample was higher than the known value of 1.36 Bqlsample, which exceeded the upper control limit of 1.77 Bq/sample. No errors were found in the calculation or procedure.

The reanalyzed result of 1.73 Bq/sample was acceptable.

3. Environmental Inc.'s MAPEP August 2011 Sr-90 in soil result of 219.4 Bq/kg, less than the known value of 320 Bqokg, was below the lower control limit of 224 Bq/kg. The sample was reanalyzed in triplicate through a strontium column. The reanalyzed result of 304.2 Bq/kg was acceptable.

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

Summary and Conclusions This report on the Radiological Groundwater Protection Program (RGPP) conducted for the Oyster Creek Generating Station (OCGS) by Exelon Generation Company LLC (Exelon) covers the period 01 January 2011 through 31 December 2011.

This report covers groundwater and surface water samples collected from the environment, both on and off station property in 2011. Two thousand one hundred and four analyses were performed on one thousand and seventy two samples from 65 locations.

There were three inadvertent releases of contaminated water into the groundwater during 2009. There is a plume located west of the turbine building and is monitored via a series of monitoring wells.

Gamma-emitting radionuclides were not detected in any of the groundwater well samples 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/I versus 20,000 pCi ).

As expected, tritium was detected in groundwater samples. 2011 Tritium concentrations varied from <200 to 994,000 pCi/I. The well with the highest concentration was MW-67. The flow of groundwater is In the direction of the intake and discharge canals.

No detectable tritum (greater than the MDC) was found in surface water or precipitation samples collected from onsite and offsite monitoring locations during 2011.

Strontium-89/90 was not detected in any groundwater sample during 2011.

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second quarter sampling in 2011. Since this is the first year these analyses were performed as part of the RGPP for Oyster Creek, these results will be utilized to establish baseline levels.

There were 47 samples taken from 42 groundwater well locations. Gross Alpha (dissolved) was detected in 9 samples and ranged from 0.4 to 5.7 pCi/L. Gross Alpha (suspended) was detected in 19 samples and ranged from 1.2 to 19.9 pCi/L. Gross Beta (dissolved) was detected in 45 samples and ranged from 1.3

to 109 pCi/L. Gross Beta (suspended) was detected in 22 samples and ranged from 1.8 to 77.5 pCI/L.

"Hard-To-Detect analyses were performed on a select group of groundwater locations to establish baseline levels. The analyses for groundwater included Fe-55, NI-63, Am-241, Cm-242, Cm-2431244, Pu-238, Pu-239/240, U-234, U-235, and U-238. The isotopes of U-234 and U-238 were detected in three of nine groundwater monitoring locations. The U-234 concentrations ranged from 0.41 to 1.74 pCI/I and the U-238 concentrations ranged from 0.44 to 1.81 pCi/L.

The levels detected are considered background.

II. Introduction The Oyster Creek Nuclear Generating Station consists of a single boiling water reactor (BWR) and turbine generator capable of producing 650 megawatts of electricity. The Station operates under Nuclear Regulatory Commission (NRC) renewed facility operating license number DPR-16. Brackish water from Bamegat Bay is supplied to the circulating water system. The circulating water system is designed to supply a continuous flow of water from Bamegat Bay through the plant to remove the waste heat releasedby the power cycle in the Main Condenser. The circulating water system is comprised of the intake canal from Bamegat Bay to the plant, the Main Condenser Circulating Water System, the dilution plant, and the discharge canal to Barnegat Bay. The dilution plant portion, of the system minimizes the adverse effects of hot discharge water on aquatic life in the discharge canal and Bamegat Bay to meet the conditions of the Oyster Creek New Jersey Pollutant Discharge Elimination system (NJPDES)

Permit No. NJ0005550. Approximately 1 million gallons per minute of water are withdrawn from the intake canal for dilution and station use and retumed to the discharge canal.

The Station Is located in the Atlantic Coastal Plain physiographic province.

Topography in the region of the Station is a slightly undulating coastal plain having low relief.: The land surface gradually rises from sea level at Bamegat Bay,. which is located east of the Station, to approximately 50 feet above mean sea level (AMSL) 2 miles inland. This region of the coastal plain has numerous tidal marshes and is incised by easterly flowing streams and creeks. Elevations at the Station property west of Route 9 range from approximately 0 to 15 feet AMSL immediately adjacent to the intake and discharge canals to slightly more than 30 feet AMSL in the northwest portion of the Station property. The 132-acre developed portion of the Site located within the "horseshoe" formed by the intake and discharge canals west of Route 9 has an approximate average elevation of 20 feet AMSL. In the immediate vicinity of the intake and discharge canals, the Station property slopes steeply down to the canal. The average elevation of the surface water level in the intake and discharge canals is approximately 1-foot AMSL. The remaining 637-acre portion of the Station located east of Route 9 is primarily vegetated and undeveloped. The ground surface is relatively level exceptifor the steep slopes at areas adjacent to the intake and discharge canals.

The three shallowest stratigraphic units in the vicinity of the Oyster Creek area in descending order are the Cape May Formation, the Cohansey Formation, and the Kirkwood Formation. Some of the Station structures are constructed to depths of approximately 50 feet below ground surface (bgs). Excavations were completed from grade, through the fill, Cape May Formation, Upper Clay, and into the Cohansey Formation during construction. Consequently, the bottoms of

some Station structures are completed within the Cohansey Formation and some structures breach the Upper Clay.

The Cape May Formation regionally-has an average thickness of 40 feet and at OCGS, the Cape May is described as a light gray to tan, medium- to fine-grained sand, with trace to some silt and occasional coarse sand. It is generally poorly compacted. The Cape May Formation vares from 0 to 21 feet in thickness based on historical boring logs. The variation principally is due to the varying amount of material excavated and replaced by fill during Station construction.

When present, the thickness of the Cape May generally ranges from 15 to 20 feet thick. The base of the Cape May generally is defined by the presence of a dark clay unit referred to as the Upper Clay unit. The Upper Clay is a stiff to hard, gray, plastic organic clay containing inclusions (also described as lenses or partings) of dense fineisand with trace to some organic silt. The deposits of fine sand within the Upper Clay layer have high relative densities and occur as lenses or inclusions.

The Cohansey Formation is primarily composed of a light-colored, fine- to very coarse-grained quartzose sand with lenses of silt and clay. Although most borings at the Station do not penetrate the entire Cohansey Formation, this formation appears to be approximately 60 to 80 feet thick at OCGS. A clay sequence, referred to at the Station as the "Lower Clay", marks the base of the Cohansey, which generally is present to approximately 90 to 100 feet bgs. The lower day is a dense gray medium- to fine-gralned sand containing trace to some organic sift and layers or inclusions of very stiff: to hard gray organic clay.

The thickness of the lower day is estimated to be approximately 10 to 20 feet in the vicinity of OCGS.

The Cohansey Formation is underlain by the Kirkwood Formation which consists of several stratigraphic units., The Kirkwood Formation is described as a.:

medium- to fine-grained sand with trace sift. The thickness of this formation beneath the Station is unknown. The south domestic supply well terminates in the Kirkwood at a depth of 310 feet bgs. The Kirkwood thickness in Ocean County ranges from approximately 300 to 400 feet.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. (Midwest Labs) on samples collected in 2011.

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

B. Implementation of the Objectives,,

The objectives identified have been implemented at the Oyster Creek Generating Station through compliance with approved procedures EN-AA-408-4000, Radiological Groundwater Protection Program Implementation and site specific procedure EN-OC-408-4160, RGPP Reference Material for Oyster. Creek Generating Station.*

C. Program Description Samples for-the OCGS site were collected for Exelon by on-site personnel and Normandeau Associates, Inc.-Thls section describes the general collection methods used to obtain environmental samples for the OCGS RGPP in 2011. Sample locations can be found in Table A-I, Appendix A.

1. Sample Collection Samples of water are collected, managed, transported and analyzed in accordance with approved procedures. 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, S2. Sample Analysis Samples are analyzed in accordance with approved procedures that are based on industr*,standards.

3. Quality Control Analytical laboratories are subject to intemal quality assurance programs, industry cross-check programs, nuclear industry audits, as well as being certified by the State of New Jersey.

4. Data Interpretation Station personnel review and evaluate all analytical data deliverables as data is 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 tritlum is tritlum oxide, which Is also called "tritiated water." The chemical properties of titium 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 10 days.

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. Also, Mtium was released Into the atmosphere from Chernobyl in 1986. Like normal water, tMtiated water is colorless and odorless. Tritlated water behaves chemically and: physically like non-tritiated water in the subsurface, and therefore Mtiated 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 trtium 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 descrbes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the Oyster Creek Generating Station RGPP inW2011. The sampling frequencies are increased if activity is detected.,.

In order to achieve the stated objectives, the current program includes the

following analyses for groundwater, surface water, and precipitation water:

1. Gamma emitters

2. Gross strontium, Strontium-89 and Strontium-90

3. Tritium

4. Gross Alpha, Dissolved and Suspended and Gross Beta, Dissolved and Suspended

5. Selected transuranics  :

6. Fe-55

7. NI-63 B. Data Interpretation The radiological data collected prior to Oyster Creek Generating Station becoming operational, aswell as background data from publicly available databases, were used as abaselineowith 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-thedata:

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 "realr 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 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 as an after the fact estimate of the presence of activity.

,2.

Laboratory Measurements Uncertainty The estimated uncertainty in, measurement of tritMum 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 (t) 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.

C. Background Analysis S1. 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 Mtum 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',titium 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 tritum 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 peaked in 1963 with the signing of the limited test ban treaty. 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 Chemobyl in 1986.

b. Precipitation Data Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides. One publicly available database that provides tritium concentrations in precipitation is the USEPA's RadNet database. RadNet provides tritium precipitation concentration date for samples collected at stations throughout the U.S. from 1978 up to and Including 1996.

Tritium concentrations in precipitation in New Jersey from 1978 through 1996 have ranged from 600 pCi/I in 1979 to 0 pCi/i in 1996, with an average of 185 pCi/I. Tritium concentrations in wells may still be above the 200 pCi/I 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 surface water bodlesi including Oyster Creek and the Delaware River. New Jersey surface water data between 1978 and 1998 averaged 185 pCII.

The USEPA RadNet surface water data typically.has a reported 'Combined Standard Uncertainty' of 2 standard deviations. This corresponds to a +/-36 to i100 pCi/I confidence bound on each given reported measurement so that the typical surface water background data provided by RadNet may~be subject to measurement uncertainty of up to 100 pCui/.

The radio-analytical laboratory counts tritium results to an Exelon specified LLD of 200 pCl/I with a typical uncertainty of *100 pCil., Therefore, sample results reported by TBE near this LLD can not be distinguished from natural background concentrations in surface water.

IV. Results and Discussion A. Program Exceptions

1. Sample Anomalies.

There are no samples anomalies in 2011..

2. Missed Samples Exeion maintains a Radiological Groundwater Protection Program (RGPP) as part of thenuclear industry's voluntary groundwater protection initiative as described in NEI 07-07. As part of this program, samples are obtained routinely from monitoring wells and surface waters at Oyster Creek based on the frequencies outlined in station procedures. The following samples were not obtained as required by procedure:

MW-51

. Gamma, semiannually, Gross alpha, annually

. Gross beta, annually

• Seliecttransuranics, annually

- Iron-55, annually

- Nickel-63, annually

- Strontium-89, annually

- Strontium-90, annually Immediate actions taken:

MW-51 was dry 11 out of 12 months during sampling events. The one month a sample was obtained, there was only enough sample to perform tritium analysis. MW-51 is checked for water each sampling event and no additional actions are required.

3. LLDs Not Met Required LIDs for Surface and Groundwater H-4 2l 1Is Zi45 30 Nb4, 15 Zr.M 30 1-131 1s C-I1)4 15 Ce-137 13 Bm.140 60 L1.I0.1,0 15 Indicated LLDs for shorter lived radionuclides were not met due to a time lag between taking the samples and analyzing the samples as Indicated on table B-1.2 and B-11.2.

B. Groundwater Results Samples were collected from on-site locations in accordance with the station radiological groundwater protection program. As reported in CRA's 2006 Hydrogeologic Investigation Report, groundwater flow in the vicinity of the Torus Water Storage Tank and the Condensate Storage Tank is towards the intake and discharge canals.

Tritium Samples from 55 locations were analyzed for tritium activity (Table B-..1, Appendix B). Tritium was detected in 11.8.of 319 samples.

The values ranged from < 200 to 994,000 pCi/l. The well with the highest concentration was -MW-67 (Table B-1.1, Appendix B).

Strontium-90 was not detected in any location sampled in 2011.

(Table B-1.1. Appendix B)

Gross Alpha and Gross Beta (dissolved and suspended)

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second sampling in 2011.

There were 47 samples taken from 42 groundwater well locations.

Gross Alpha (dissolved) was detected in 9 samples and ranged from 0.4 to 5.7 pCi/L. Gross Alpha (suspended) was detected in 19 samples and ranged from 1.2 to 19.9 pC01L. Gross Beta (dissolved) was detected in 45 samples and ranged from 1.3 to 109 pCi/L. Gross Beta (suspended) was detected in 22 samples and ranged from 1.8 to 77.5 pCi/IL (Table B-1.1, Appendix B).

Gamma Emitters No gamma emitting nuclides were detected in any of the samples analyzed during 2011 (Table B-1.2, Appendix B).

"Hard-To-Detect" "Hard-To-Detect' analyses were performed on a select group of groundwater locations to establish background levels. The analyses for groundwater included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235, and U-238. The isotopes of U-234 and U-238 were detected in three of nine groundwater monitoring locations. The U-/234 concentrations ranged from 0.41 to 1.74 pC1.1 and the U-238 concentrations ranged from 0.44 to 1.81 pCi/L. The levels detected are considered background due to naturally occurring U-234 and U-238 (Table B-1.3, Appendix B).

C. Surface Water Results
