I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Peach Bottom Atomic Power Station (PBAPS) by Exelon Nuclear covers the period 1 January 2003 through 31 December 2003. During that time period, 1090 analyses were performed on 901 samples.

Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No fission or activation products were found. Tritium levels were consistent with those observed in previous years and lower than levels seen during the preoperational years.

Drinking water samples were analyzed for concentrations of gross beta (soluble and insoluble fractions), tritium, and gamma emitting nuclides. No fission or activation products were found. Gross beta and tritium activities detected were consistent with those observed in previous years.

The remaining sample media representing the aquatic environment included fish and sediment samples. These media were analyzed for concentrations of gamma emitting nuclides. Fish samples showed no detectable fission or activation products from the operation of PBAPS. Cesium-137 activity was found at most sediment locations and was consistent with data from previous years. Co-60 was found at the nearest downstream sediment sampling location. The dose to a teenager's skin from the sediment pathway was calculated to be 9.24 E-04 mrem/year, which represents 0.005% of the allowable fraction of 10 CFR 50, Appendix I limits.

The atmospheric environment was divided into two parts for examination: airborne and terrestrial. Sample media for determining airborne effects included air particulates and air iodine samples. Analyses performed on air particulate samples included gross beta and gamma spectrometry. No fission or activation products were found. The gross beta results were consistent with results from the previous years. Furthermore, no notable differences between control and indicator locations were observed. These findings indicate no measurable effects from the operation of PBAPS.

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

Examination of the terrestrial environment was accomplished by analyzing milk samples for low level concentrations of lodine-131 and gamma emitting nuclides.

No fission or activation products were found.

Ambient gamma radiation levels were measured quarterly throughout the year. All measurements were below 10 mR/standard month and the results were consistent with those measured in previous years.

The results of the TLD monitoring program were used to determine if the Independent Spent Fuel Storage Installation (ISFSI) had any measurable impact on the dose rate in the environs. One on-site location showed an increase dose of 0.6 to 1 mR per standard month. No increase in dose was evident at the nearest residence.

In assessing all the data gathered for this report and comparing these results with preoperational data, it was evident that the operation of PBAPS had no adverse radiological impact on the environment.

II. Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, Pennsylvania. The initial loading of fuel into Unit 1, a 40 MWe (net) high temperature, gas-cooled reactor, began on 5 February 1966, and initial criticality was achieved on 3 March 1966. Shutdown of Peach Bottom Unit 1 for decommissioning was on 31 October 1974. For the purposes of the monitoring program, the beginning of the operational period for Unit 1 was considered to be 5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report (1). PBAPS Units 2 and 3 are boiling water reactors, each with a power output of approximately 1170 MWe. The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality was achieved on 16 September 1973, and full power was reached on 16 June 1974. The first fuel was loaded into Peach Bottom Unit 3 on 5 July 1974. Criticality was achieved on 7 August 1974, and full power was first reached on 21 December 1974.

Preoperational summary reports (2)(3) for Units 2 and 3 have been previously issued and summarize the results of all analyses performed on samples collected from 5 February 1966 through 8 August 1973.

A. Objectives The objectives of the REMP are:

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

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

B. Implementation of the Objectives 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 plant Station operation to assess Station radiological effects (if any) on man and the environment.

Ill. Program Description A. Sample Collection Normandeau Associates, RMC Environmental Services Division (RMC),

collected samples for the PBAPS REMP for Exelon Nuclear. This section describes the general collection methods used by RMC to obtain environmental samples for the PBAPS REMP in 2003. Sample locations and descriptions can be found in Table B-1, and Figures B-1 through B-3, Appendix B. The collection procedures used by RMC are listed in Table B-2, Appendix B.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, fish, and sediment. Surface water from two locations (1LL and 1MM) and drinking water from two locations (4L and 61) were collected weekly by automatic sampling equipment. Weekly samples from each of the surface and drinking water locations were composited into a separate monthly sample for analysis.

Approximately, two quarts of water were removed from the weekly sample container and placed into a clean two-gallon polyethylene bottle to form a monthly composite. Control locations were 1LL and 61. Fish samples comprising the flesh from two groups: Bottom Feeder (catfish) and Predator (smallmouth bass, largemouth bass, or bass) were collected semiannually from two locations: 4 and 6 (control). Sediment samples composed of recently deposited substrate were collected semiannually at three locations:

4J, 4T and 6F (control).

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on air particulate, airborne iodine and milk samples. Air particulate and air iodine samples were collected and analyzed weekly from five locations (1B, 1Z, 1C, 3A, and 5H2). The control location was 5H2. Airbome 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 1 cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis.

Milk samples were collected biweekly at five locations (A, J, 0, R and S) from April through November and monthly from December through March.

Seven additional locations (B, C, D, E, L, and P) were sampled quarterly.

Locations A, B, C, and E were controls. All samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory.

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

Assite bhundajy ring, consisting of 18 locations (1L, 1P, 1A, 1Q, 1D, 2, IM, 1R, 11, 1C, 1J, 1F, 40, 1NN, 1H, IG,1B, and 1E), near and within the site perimeter representing fence post doses (i.e., at locations where the doses will be potentially greater than maximum annual off-site doses) from PBAPS releases.

An inmediate distance ring, consisting of 19 locations (15, 22, 44, 32, 45, 14, 17, 31A, 4K, 23, 27, 48, 3A, 49, 50, 51, 26, 6B, and 42), extending to approximately 5 miles from the site and designed to measure possible exposures to close-in population.

The balance of nine locations (2B, 43, 5, 16, 24, 46, 47, 18, and 19) representing control and special interests areas such as population centers, schools, etc.

The specific TLD locations were determined by the following criteria:

1. The presence of relatively dense population;

2. Site meteorological data taking into account distance and elevation for each of the 36 ten-degree sectors around the site, where estimated annual dose from PBAPS, if any, would be more significant;

3. On hills free from local obstructions and within sight of the vents (where practical);

4. And near the dwelling closest to the vents in the prevailing down wind direction.

Two TLDs - each comprised of three CaSO4 themoluminescent phosphors enclosed in plastic - were placed at each location in a Formica "birdhouse" or polyethylene jar located approximately six feet above ground level. The TLD sets were exchanged quarterly, then sent to the laboratory for analysis.

B. Sample Analysis This section describes the general analytical methods used by Teledyne.

Brown Engineering and Environmental Inc. to analyze the environmental samples for radioactivity for the PBAPS REMP in 2003. The analytical procedures used by the laboratories are listed in Table B-2, Appendix B.

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

1. Concentrations of beta emitters in drinking water and air particulates.

2. Concentrations of gamma emitting nuclides in surface and drinking water, air particulates, milk, fish, and sediment.

3. Concentrations of tritium in surface and drinking water.

4. Concentrations of 1-131 in air and milk.

5. Ambient gamma radiation levels at various site environs.

C. Data Interpretation The radiological and direct radiation data collected prior to PBAPS becoming operational was used as a baseline with which these operational data were compared. For the purpose of this report, PBAPS was considered operational at initial critically. In addition, data were compared to previous years' operational data for consistency and trending. Several factors are important in the interpretation of the data. These factors were important in the interpretation of the data:

1. Lower I imit 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 criteria for the presence of activity. All analyses were designed to achieve the required PBAPS 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 will result in sample activity being lower than the background activity effecting 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 drinking 11 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, Cs-134, Cs-137, Ba-140, and La-140 were reported.

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

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

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

For milk five nuclides, K-40, Cs-134, Cs-137, 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 2003 the PBAPS REMP had a sample collection recovery rate of better than 99%. The exceptions to this program are listed below:

1. The TLD for location 2B was lost for the period 10/01/2003 to 01/01/2004 due to vandalism.

2. The TLD for location 45 was lost for the period 10/01/2003 to 01/01/2004 due to vandalism.

3. Air particulate and air iodine samples from location 1Z because of low air volume for the period 09/12/2003 to 09/18/2003 due to a short run time from a blown fuse. The gross beta LLD of 0.01 pCilcu.m. was missed due to the low sample volume.

4. The air particulate from location 5H2 for week 10/20/2003 to 10/27/2003 was lost by the laboratory. The 4t quarter 2003 air particulate composite consisted of 12 air particulates rather than the normal 13.

Each program exception was reviewed to understand the causes of the program exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent a recurrence. Occasional equipment breakdowns and power outages were unavoidable.

E. Program Changes ICN Pharmaceutical was renamed Global Dosimetry in 2003.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were taken from a continuous sampler at two locations (1LL and 1MM) on a monthly schedule. Of these locations, 1MM located downstream, could be affected by Peach Bottom's effluent releases.

The following analyses were performed:

TrLitum Monthly samples from both locations were composited quarterly and analyzed for tritium activity (Table C-1.1, Appendix C). No tritium activity was detected. Results ranged from <174 to <200 pCi/A and averaged 187 pCi/A at the control location and 181 pCi/A at the indicator location.

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

2. Drinking Water Monthly samples were collected from continuous water samplers at two locations (4L and 61). One location (4L) could be affected by Peach Bottom's effluent releases. The following analyses were performed:

Gross Beta Samples from both locations were analyzed for concentrations of gross beta activity in insoluble and soluble fractions (Tables C-11.1 and C-11.2 and Figures C-1 and C-2, Appendix C). The values ranged from <1.3 to 2.0 pCi/A for the insoluble fraction and from <1.8 to 3.7 pCUI for the soluble fraction. Concentrations detected in both fractions were generally below those detected in previous years.

Tritium Monthly samples from both locations were composited quarterly and analyzed for tritium activity (Table C-11.3, Appendix C). No tritium activity was detected. The highest MDA calculated was <189 pCi/

Gamma Spectrometry Samples from both locations were analyzed for gamma emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDA.

3. Eish Fish samples comprised of bottom feeder (catfish) and predator (bass) were collected at two locations (4 and 6) semiannually.

Location 4 could be affected by Peach Bottom's effluent releases.

The following analysis was performed:

Gamma Spectrometr The edible portion of fish samples from both locations was analyzed for gamma emitting nuclides (Table C-111.1, Appendix C). Naturally occurring K-40 was found at all stations and ranged from 2,610 to 4,290 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found. Historical levels of Cs-137 are shown in Figure C-3, Appendix C.

4. Sediment Aquatic samples were collected at three.locations (4J, 4T and 6F) semiannually. Of these locations two, 4J and 4T located downstream, could be affected by Peach Bottom's effluent releases. The following analysis was performed:

Gamma Spectrometry Sediment samples from all three locations were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). Nuclides detected were naturally occurring K-40 and the fission product Cs-137.

Potassium-40 was found at all stations and ranged from 11,300 to 21,700 pCi/kg dry. Concentrations of the fission product Cs-1 37 were found in sediment samples in most locations. Location 4T had the highest average concentration of 179 pCi/kg dry. The activity detected was consistent with those detected in the pre-operational years (Figure C-4, Appendix C). Co-60 was found at the nearest downstream sediment sampling location. Location 4J had an average concentration of 47 pCi/kg dry. No other Peach Bottom fission or activation products were found.

B. Atmospheric Environment

1. Airborne

a. Air Particulates Continuous air particulate samples were collected from five locations on a weekly basis. The five locations were separated into three groups: Group I represents locations within the PBAPS site boundary (I B, 1Z and 1C), Group II represents the location at an intermediate distance from the PBAPS site (3A),

and Group IlIl represents the control location at a remote distance from PBAPS (5H2). The following analyses were performed.

Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Tables C-V.1 and C-V.2 and Figures C-5 and C-6, 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 PBAPS. The results from the On-Site locations (Group I) ranged from <5 to 43 E-3 pCim 3 , with a mean of 18 E-3 pCiM 3. The results from the Intermediate Distance location (Group II) ranged from 6 to 51 E-3 pCi/M 3 with a mean of 18 E-3 pCrM3. The results from the Distant location (Group lIlI ranged from 6 to 38 E-3 pCi/M3 with a mean of 17 E-3 pCVir A comparison of the weekly mean values for 2003 indicate no notable differences among the three groups (Figure C-5, Appendix C). In addition, a comparison of the 2003 air particulate data with previous years data indicate no effects from the operation of PBAPS (Figure C-6, Appendix C).

Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-V.3, Appendix C). Naturally occurring Be-7 due to cosmic ray activity was detected in all samples. These values ranged from <7 to 66 E-3 pCiM3 . All other nuclides were less than the MDA.

b. Airbome Iodine Continuous air samples were collected from five locations (1B, IZ, 1C, 3A, and 5H2) and analyzed weekly for 1-131 (Table C-VI.1, Appendix C). All results were less than the MDA.

2. Terrestrial

a. Milk Samples were collected from five locations (A, J, 0, P, R, and S) biweekly April through November and monthly December through March. Samples from six additional locations (B,C, D, E, L, P) were taken quarterly. The following analyses were performed.

Iodine-I 31 Milk samples from all locations were analyzed for concentrations of 1-131 (Tables C-VII.1, Appendix C). All results were less than the MDA.

Gamma Spectrometry Each milk sample from locations A, J, 0, R and S .was analyzed for concentrations for gamma emitting nuclides (Table C-VI1.2, Appendix C).

Naturally occurring K-40 was found in all samples and ranged from 1040 to 1,530 pCVI. All other nuclides were less than the MDA. Comparison of the 2003 Cs-137 milk data with previous years data indicate no effects from the operation of PBAPS (Figure C-7 (Appendix C).

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured using Panasonic 814 (CaSO 4 ) thermoluminescent dosimeters. Forty-six TLD locations were established around the site. Results of TLD measurements are listed in Tables C-VIII.1 through C-VIlI.3 and Figure C-8, Appendix C.

All TLD measurements were below 10 mR per standard month, with a range of 2.4 to 7.9 mR per standard month. A comparison of the Site Boundary and Intermediate Distance data to the Control locations data indicate that the ambient gamma radiation levels from the Control locations 16, 18, 19 and 24 were essentially the same as the other locations. The historical ambient gamma radiation data from the Control locations was plotted along with similar data from the Site and the Intermediate Distance locations (Figure C-8, Appendix C)

D. Independent Spent Fuel Storage Installation (ISFSI)

The Independent Spent Fuel Storage Installation (ISFSI) was utilized beginning June 2000. As of 2003, a total of 20 TN-68 casks, each loaded with 68 fuel bundles were in place on the ISFSI pad. As part of the overall REMP, additional TLDs were placed at locations near the site boundary and at the nearest resident. Although there was a general trend for decreased dose at all REMP locations (see Figure C-8, Appendix C), Onsite location 1R, which is located on the hillside overlooking the ISFSI showed an increase trend of 0.5 to 1 mR per standard month when compared to controls (Figure C-9, Appendix C). Location 2B, which represents the nearest residence showed no increase in dose rates when compared to controls. Data from location 2B is used to demonstrate compliance to both 40CFR190 and 10CFR72.104 limits.

E. Land Use Census A Land Use Survey conducted during May to.October 2003 growing season around the Peach Bottom Atomic Power Station (PBAPS) was performed by Normandeau Associates, Inc., RMC Environmental Services Division for Exelon Nuclear to comply with Section 3.8.E.2 of PBAPS's Offsite Dose Calculation Manual Specifications (ODCMS) and Bases. The purpose of the survey was to document the nearest milk producing animal in each of the sixteen meteorological sectors out to five miles. In addition, the nearest residence and garden of >500 square feet were documented. The distance and direction of all locations were positioned using Global Positioning System (GPS) technology. There were no changes required to the PBAPS REMP as a result of this survey. The results of this survey are summarized below.

APPENDIX D DATA TABLES AND FIGURES COMPARISON LABORATORY

The following section contains data and figures illustrating the analyses performed by the QC laboratory, Environmental, Inc. Duplicate samples were obtained from several locations and media and split between the primary laboratory, Teledyne Brown Engineering (TBE) and the QC laboratory. Comparison of the results for most media were within expected ranges.

The QC laboratory results for gross beta insoluble and soluble in drinking water samples were very similar to those reported by the Primary laboratory. All results between the laboratories were within 4 pCi/l of each other. The data reported were well within the historical range.
