Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Oyster Creek Generating Station (OCGS) by AmerGen Energy Company covers the period 01 January 2004 through 31 December 2004. During that time period, 1206 analyses were performed on 1022 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 well water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No fission, activation products or tritium were detected.

Fish (predator and bottom feeder), clams, crabs, and sediment samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected in fish, clams, or crabs. Cesium-137 levels detected in sediment were consistent with levels detected in previous years and were due to previous plant releases and fallout from nuclear weapons testing. No other OCGS-produced fission or activation products were detected in 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. Cesium-1 37 was detected at low levels consistent with those detected in previous years. All strontium-89 results were below the minimum detectable activity. Strontium-90 activity was detected at low levels in both control and indicator stations.

Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters. Levels detected were consistent with those observed in previous years.

Introduction The Oyster Creek Generating Station (OCGS), consisting of one boiling water reactor owned and operated by AmerGen Energy Company, 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 % mile west of the highway and 11% 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 Radiological Environmental Monitoring Program (REMP) for OCGS was initiated in 1966. 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 2004 through 31 December 2004.

A.

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

1.

Assess dose impacts to the public from the OCGS operations.

2.

To verify in-plant controls for the containment of radioactive materials.

3.

To monitor any buildup of long-lived radionuclides in the environment and changes in background radiation levels.

4.

To provide reassurance to the public that the program is capable of adequately assessing impacts and identifying noteworthy changes in the radiological status of the environment.

5.

Provide data on measurable levels of radiation and radioactive materials in the site environs.

2

6.

Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.

7.

To fulfill the requirements of the OCGS Offsite Dose Calculation Manual (ODCM) and Technical Specifications.

B.

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

1.

Identifying significant exposure pathways.

2.

Establishing baseline radiological data of 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.

Program Description A.

Sample Collection Samples for the OCGS REMP were collected for AmerGen Energy Company by on-site personnel and Normandeau Associates, RMC Environmental Services Division (RMC). This section describes the general collection methods used to obtain environmental samples for the OCGS REMP in 2004. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1 and B-2, 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, well water, fish, clams, crabs, and sediment. One gallon surface water samples were collected monthly from two locations (33 and 94), semiannually at two locations (23 and 24), and quarterly from three well water locations (1, 37, and 38). 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 two locations (93 and 94 (control)). Clams were collected semiannually from three locations (23, 24, and 94 (control)).

3

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, airborne iodine, and vegetation.

Airborne iodine and particulate samples were collected and analyzed weekly at seven locations (C, 3, 20, 66, 71, 72, and 73). 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.

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. 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 16 locations (1, 51, 52, 53, 54, 55, 56, 57, 58, 59, 61, 62, 63, 64, 65 and 66) near the boundary.

An intermediate distance ring consisting of 16 locations (4, 5, 22, 47, 48, 68, 73, 74, 75, 79, 82, 84, 85, 86, 98, and 99) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.

Special interest stations consisting of 15 locations (3, 6, 8, 9, 11, 46, 71, 72, 78, 81, 88, 89, 90, 92, and T1) 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.

4

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 land-based meteorological sector in the 6 to 8 kilometer 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 Global Dosimetry for analysis.

B.

Sample Analysis This section describes the general analytical methodologies used by TBE and Midwest Labs to analyze the environmental samples for radioactivity for the OCGS REMP in 2004. 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 well water, fish, clams, crabs, sediment, air particulates, and vegetation.

3.

Concentrations of tritium in surface and well 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 2004 were compared with data from past years. For the purpose of this report, OCGS preoperational data was not used due to its collection 35 years ago. Several factors were important in the interpretation of the data:

5

I.

Lower Limit of Detection and Minimum Detectable Activity The lower limit of detection (LLD) was 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 was 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 activity (MDA) 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 Reporting 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 MDA 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 well 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-134, and Cs-137 were reported.

For clams eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-134, and Cs-137 were reported.

For crabs eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-134, and Cs-137 were reported.

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

6

For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

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

For vegetation four nuclides, K-40, 1-131, Cs-134, and Cs-1 37, 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 2004 the OCGS REMP had a sample recovery rate in excess of 99%.

Exceptions are listed below:

In March 2004, the REMP air samplers were modified to include a calibrated restricted-flow orifice. An incorrect fitting had been installed in the system which allowed in-leakage of air that bypassed the filters. This situation was recognized and corrected within eight calendar days. The contractor responsible for sampler modification assessed the situation and found that 50 percent of the total volume at each station was a result of this air in-leakage. Therefore, the total volumes for samples collected during this period were reduced to capture the air bypass. Even with this situation, continuous sampling at all sites continued and all required LLDs were met. There was no ODCM violation due to this situation. This event was self-identified and documented in the Corrective Action Process as CAP # 02004-0854.

In July 2004, the Sample Collection Vendor failed to ship previously collected REMP samples to the analysis laboratory within two (2) days of collection as required by Sample Collection procedures. The analysis vendor was able to meet all required LLDs and there was no ODCM violation due to this situation. This event was self-identified and documented in the Corrective Action Process as CAP # 02004-1725.

In July 2004, two TLDs at REMP Station # 68 had fallen out of the holder and were found lying on the ground. Data from these TLDs is questionable. This station is not required by the ODCM. In an effort to prevent further loss of TLDs, three non-ODCM required stations, Stations 68, 98, and 99, all located on mile-markers on the Garden State Parkway, were each relocated 100 feet east of their original locations on 05 Oct 04.

This event was self-identified and documented in the Corrective Action Process as CAP # 02004-1854.

7

In September 2004, a test vacuum gauge used by the sample collector to check the vacuum of the REMP air samplers failed in the field. This piece of test equipment is carried along with the sampler during filter exchange and is not an integral component of the air samplers. This had no impact on any air sampler operation. This event is self-identified and documented in the Corrective Action Process as CAP # 02004-2455.

In September 2004, a sample collected from the ODCM required Air Sampler # 73 did not meet the required analytical lower limit of detection (LLD) for gross beta of 1.00 E-7 pCi/cubic meters, as required by the ODCM. The LLD achieved was 1.07 E-2 pCi/cubic meters. Subsequent investigation discovered that this air sampler failed after operating for 92.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and collected only 153.8 cubic meters of sample. Typically, the total volume collected is approximately twice what was collected at this station.

The less than typical total volume collected at this station resulted in the lower limit of detection being missed. This event was self-identified and documented in the Corrective Action Process as CAP # 02004-4015.

In January 2005, the TLDs at station 78 were found missing. This event was self-identified and documented in the corrective action process as CAP #02005-1711.

Each program exception was captured under the corrective action process which resulted in an investigation to understand the causes of the program exception. Sampling and maintenance errors were 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 The Oyster Creek ODCM was revised in October 2004 regarding the wording in Table 3.12.1-1, Section 1 (Direct Radiation). This revision was required because seven TLD stations could not be located within the required 6 to 8 kilometer range because these locations were in sectors that are either located over water or in sectors where there is no highway access. In order to accomplish full compliance with this revision, TLD Stations 4, 5, 46, 47, and 48 were included as ODCM required stations.

Table E-1, UREMP Sample Locations" and Figure E-2, 'Sampling Locations Outside 2 Miles" were also revised to capture these changes.

This event was self-identified and documented in the Corrective Action Process and CAP # 02004-2798.

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 tritium activity was detected. The highest MDA was calculated at <190 pCi/I.

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

2.

Well Water Quarterly samples were composited from monthly grab samples at three locations (1, 37, and 38). Two locations (1 and 38) could be affected by Oyster Creek's effluent releases. The following analyses were performed:

Tritium Quarterly samples from all locations were analyzed for tritium activity (Table C-11.1, Appendix C). No tritium activity was detected. The highest MDA was calculated at <190 pCi/I.

9

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

3.

Fish Fish samples comprised of tautog and flounder (bottom feeder) and weakfish, striped bass, white perch, sea bass, bluefish, and puffer (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:

Gtamma 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 2,520 to 4,850 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.

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:

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 839 to 1,270 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-I, Appendix C.

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 2,290 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.

10

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). Nuclides detected were naturally occurring Be-7 and K-40, and the fission product Cs-1 37.

Beryllium-7 was found in three sediment samples. Location 23 had an average concentration of 335 pCVkg dry and ranged from 142 to 528 pCi/kg dry. Location 94 had an average concentration of 192 pCikg dry and ranged from <132 to 251 pCikg dry. Potassium-40 was found at all stations and ranged from 295 to 14,200 pCi/kg dry.

Concentrations of the fission product Cs-137 were found in three sediment samples. Location 23 had an average concentration of 20 pCi/kg dry and ranged from 14 pCi/kg dry to 26 pCikg dry.

Location 33 had an average concentration of 10 pCi/kg dry and ranged from <13 to 23 pCi/kg dry. The activities detected were consistent with those detected in previous years (Figure C-3, Appendix C). No other Oyster Creek fission or activation products were found. Figure C-2, Appendix C graphs Co-60 concentrations in sediment from 1984 through 2004.

Airborne

a.

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

11

Girass Reta 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 aid 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 33 E-3 pCi/M3 with a mean of 16 E-3 pCi/m. The results from the Intermediate Distance locations (Group II) ranged from <6 to 37 E-3 pCi/M3 with a mean of 14 E-3 pCi/m. The results from the Distant locations (Group l1l) ranged from <6 to 38 E-3 pCi/M3 with a mean of 14 E-3 pCi/M3. Comparison of the 2004 air particulate data with previous years data indicate no effects from the operation of OCGS (Figure C-5, Appendix C). In addition a comparison of the weekly mean values for 2004 indicate no notable differences among the three groups (Figure C-4, Appendix C).

Strontium-89 and Strontium-9o Weekly samples were composited quarterly and analyzed for strontium-89 and strontium-90 (Table C-V.3, Appendix C).

No strontium was detected.

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. These values ranged from 32 to 80 E-3 pCi/rn3. All other nuclides were less than the MDA.

b.

Airborne Iodine Continuous air samples were collected from seven (C, 3, 20, 66, 71, 72, and 73) locations and analyzed weekly for 1-131 (Table C-VI.1, Appendix C). All results were less than the MDA.

Terrestrial

a.

Vegetation 12

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.1, Appendix C). All strontium-89 results were less than the MDA. Strontium-90 was detected in all but two samples.

The values ranged from <3 to 60 pCi/kg wet, which is consistent with historical data.

Gamma Spectrometry Each vegetation sample from locations 35, 36, and 66 Sector 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 1,750 to 5,790 pCi/l. Cs-1 37 activity detected in three samples was consistent with those detected in previous years. All other nuclides were less than the MDA.

C.

Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic Model 814 (CaSO4) thermoluminescent dosimeters. Forty-nine TLD locations were monitored around the site. Results of TLD measurements are listed in Tables C-VI1.1 to C-VI1I.3, Appendix C.

All TLD measurements were below 20 mR/standard quarter, with a range of 7.4 to 18.2 mR/standard quarter. 2004 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 Outer Ring Locations (Figure C-7, Appendix C). The 2004 TLD results are consistent with historical data.

Land Use Survey A Land Use Survey, conducted during 2004 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.

Results obtained by Environmental, Inc. Midwest Laboratory as a participant in the Department of Energy's Mixed Analyte Performance Evaluation Program, Idaho Operations office. Idaho Falls, Idaho b All results are In Bq/kg or Bq/L as requested by the Department of Energy.

MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP.

d The cause of the deviation seems to be incomplete dissolution of the sample.

A spiked soil sample was prepared. Known activity; 32.98 pCi/g; laboratory result 33.47 pCi/g.

The sample was reanalyzed with the same results. Investigation is In progress.

g Based on the results of gamma emitting isotopes (Cs-137 and Co-0), the filter geometry appears to be biased by -10%. Addition of the summation peak at 1400 KeV results in a recalculation of 2.12 +/- 0.15 Bqlsample.
