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 2009 through 31 December 2009. During that time period, 1,180 analyses were performed on 972 samples.
Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No tritium, fission or activation products were found.
Drinking water samples were analyzed for concentrations of gross beta, 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. Low levels of tritium were detected in drinking water.
Precipitation samples were analyzed for concentrations of tritium. No tritium was detected above the Exelon specified LLD of 200 pCi/I.
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 two of three sediment locations and was consistent with data from previous years.
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 Iodine-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 and food product samples.
Milk samples were analyzed for low level concentrations of Iodine-131 and gamma emitting nuclides.
No activation or fission products were found.
Food product samples were analyzed for concentrations of gamma emitting nuclides. No Peach Bottom activation or fission products were detected.
Ambient gamma radiation levels were measured quarterly throughout the year.
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.
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.
The fourth Annual Radiological Groundwater Protection Program Report (ARGPPR) is found in Appendix F.

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 Radiological Environmental Monitoring Program (REMP) for PBAPS 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 2009 through 31 December 2009.
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 operation to assess station radiological effects (if any) on man and the environment.
Ill.
Program Description A.
Sample Collection Normandeau Associates Inc., (NAI), collected samples for the PBAPS REMP for Exelon Nuclear. This section describes the general collection methods used by NAI to obtain environmental samples for the PBAPS REMP in 2009. Sample locations and descriptions can be found in Table B-i, and Figures B-1 through B-3, Appendix B. The collection procedures used by NAI 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, precipitation, fish, and sediment. Surface water from two locations (1LL and 1MM) and drinking water from three locations (13B,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 1 LL and 61.
Precipitation samples from three locations (1A, 11B, 4M) were collected monthly.
Fish samples comprising the flesh from two groups:
Bottom Feeder (channel catfish and flathead catfish) and Predator (smallmouth bass, largemouth bass, walleye, bluegill, and green sunfish) 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). An additional set of sediment samples was collected in December to validate results.
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, 1C, 1Z, 3A, and 5H2). The control location was 5H2.
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 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 (J, R, S, T and U) from April through November and monthly from December through March. Six additional locations (C, D, E, L, P and W) were sampled quarterly. Locations C, E, and T 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.
Food product samples were collected annually at three locations (10, 2B, and 55) in October. All samples were collected in new unused plastic bags and shipped promptly to the laboratory.
Ambient Gamma Radiation Direct radiation measurements were made using Panasonic 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations were placed on and around the PBAPS site as follows:
A site boundary ring, consisting of 19 locations (1A, 1B, 1C, 1 D, 1 E, 1F, 1G, 1H, 11, 1J, 1K, 1L, 1M, 1NN, 1P, 1Q, 1R, 2, 2B, and 40), 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 intermediate distance ring, consisting of 23 locations (14, 15, 17, 22, 23, 26, 27, 31A, 32, 3A, 42, 43, 44, 45, 46, 47, 48, 49, 4K, 5, 50, 51, and 6B),
extending to approximately 5 miles from the site and designed to measure possible exposures to close-in population.
The balance of four locations (16, 18, 19, and 24) 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 2009.
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, sediment and food products.
- 3.
Concentrations of tritium in surface, drinking water and precipitation 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.
- 1.
Lower Limit of Detection and Minimum Detectable Concentration 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 concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.
- 2.
Net Activity Calculation and 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 MDC was reported in all cases where positive activity was not detected.
Gamma spectroscopy results for each type of sample were grouped as follows:
For surface and drinking 12 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-1 40, and La-1 40 were reported.
For fish eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-134, 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-137 were reported.
For milk five nuclides, K-40, Cs-1 34, Cs-137, Ba-140, and La-1 40 were reported.
For food product seven nuclides, Be-7, Mn-54, Co-58, Co-60, 1-131, Cs-134, and Cs-137 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.

Results and Discussion A.
Aquatic Environment
- 1.
Surface Water Samples were taken from a continuous sampler at two locations (1 LL and 1 MM) on a monthly schedule. Of these locations, 1 MM located downstream, could be affected by Peach Bottom's effluent releases. The following analyses were performed:
Tritium Monthly samples from both locations were composited quarterly and analyzed for tritium activity (Table C-1.1, Appendix C).
No tritium activity was detected.
Gamma Spectrometry Samples from both locations were analyzed for gamma emitting nuclides (Table C-1.2, Appendix C). All nuclides were less than the MDC.
- 2.
Drinkinq Water Monthly samples were collected from continuous water samplers at three locations (13B, 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 total gross beta activity (Tables C-11.1 and Figures C-1 Appendix C).
Gross beta was detected in 16 of 27 samples. The values ranged from 2.2 to 6.2 pCi/I. Concentrations detected were generally below those detected in previous years.
Tritium Monthly samples from both locations were composited quarterly and analyzed for tritium activity (Table C-I1.2, Appendix C).
Tritium activity was detected in two of 10 samples. The values ranged from 148 to 182 pCi/I.
Gamma Spectrometry Samples from both locations were analyzed for gamma emitting nuclides (Table C-11.3, Appendix C). All nuclides were less than the MDC.

The following analysis was performed:
Gamma Spectrometry The edible portion of fish samples from both locations was analyzed for gamma emitting nuclides (Table C-Il1.1, Appendix C).
Naturally occurring K-40 was found at all stations and ranged from 2,570 to 4,760 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.
- 5.
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-V.1, Appendix C). Potassium-40 was found in all locations and ranged from 10,200 to 17,400 pCi/kg dry.
The fission product Cs-1 37 was detected in two of six samples and ranged from 110 to 143 pCi/kg. The activity of Cs-1 37 detected was consistent with those detected in the preoperational years. 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 (1B, 1C and 1Z), Group II represents the location at an intermediate distance from the PBAPS site (3A), and Group III 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 8 to 31 E-3 pCi/m3, with a mean of 18 E-3 pCi/m3. The results from the Intermediate Distance location (Group II) ranged from 8 to 26 E-3 pCi/m3 with a mean of 17 E-3 pCi/m3. The results from the Distant location (Group Ill) ranged from 7 to 27 E-3 pCi/m3 with a mean of 16 E-3 pCi/m3 A comparison of the weekly mean values for 2009 indicate no notable differences among the three groups (Figure C-5, Appendix C). In addition, a comparison of the 2009 air particulate data with previous years data indicate no effects from the operation of PBAPS (Figure C-4, 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 18 of 20 samples. These values ranged from 42 to 119 E-3 pCi/m 3.
All other nuclides were less than the MDC.
- b.
Airborne Iodine Continuous air samples were collected from five locations (1B, 1Z, 1C, 3A, and 5H2) and analyzed weekly for 1-131 (Table C-VI.1, Appendix C).
All results were less than the MDC.
- 2.
Terrestrial
- a.
Milk Samples were collected from five locations (J, R, S, T and U) biweekly April through November and monthly December through March. Samples from six additional locations (C, D, E, L, P and W) were taken quarterly. The following analyses were performed:
Iodine-1 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 MDC.
Gamma Spectrometry Each milk sample from locations J, R, S, U and V was analyzed for concentrations of gamma emitting nuclides (Table C-VII.2, Appendix C).
Naturally occurring K-40 was found in all samples and ranged from 677 to 1,550 pCi/l. All other nuclides were less than the MDC.
Comparison of the 2009 Cs-137 milk data with previous years data indicate no effects from the operation of PBAPS (Figure C-7 (Appendix C).
- b.
Food Products Food product samples were collected at three locations (1Q, 2B and 55) when available. Of these locations two, 2B and 55, could be affected by Peach Bottom's effluent releases.
The following analysis was performed:
Gamma Spectrometry Each food product sample from locations 1 Q, 2B and 55 was analyzed for concentrations of gamma emitting nuclides (Table C-VIII.1, Appendix C).
Nuclides detected were naturally occurring Be-7, and K-40.
Beryllium-7 activity was found in 28 of 38 samples and ranged from 120 to 3,230 pCi/kg wet.
Potassium-40 activity was found in all samples and ranged from 2,210 to 8,430 pCi/kg wet. All other nuclides were less than the MDC.
C.
Ambient Gamma Radiation Ambient gamma radiation levels were measured using Panasonic 814 (CaSO4) thermoluminescent dosimeters. Forty-seven TLD locations were established around the site. Results of TLD measurements are listed in Tables C-IX.1 through C-IX.3 and Figure C-7, Appendix C.
All TLD measurements were below 10 mR per standard month, with a range of 2.9 to 8.4 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-7, Appendix C)
D.
Independent Spent Fuel Storage Installation (ISFSI)
The Independent Spent Fuel Storage Installation (ISFSI) was utilized beginning June 2000. As of 2009, a total of 44 TN-68 casks, each loaded with 68 fuel bundles, were in place on the ISFSI pad. Onsite location 1 R, which is located on the hillside overlooking the ISFSI showed a general increase of 1 to 2 mR per standard month from pre-IFSFI loading (Figure C-8, Appendix C).
Location 2B, which represents the nearest residence, showed no effect in dose rate from the IFSFI pad. 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 the 2009 growing season around the Peach Bottom Atomic Power Station (PBAPS) was performed by Normandeau Associates, Inc., NAI 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.
The results of this survey are summarized below.

Summary of Results - Inter-Laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, food products and water matrices (Appendix E). 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 laboratory results and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.
- 2.
ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.
- 3.
DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.
The MAPEP defines three levels of performance: Acceptable (flag = "A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value. Performance is acceptable with warning when a mean result falls in the range from +20% to +/-30% of the reference value (i.e., 20% < bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.
For the primary laboratory, 17 out of 18 analytes met the specified acceptance criteria. One sample did not meet the specified acceptance criteria for the following reason:
- 1.
Teledyne Brown Engineering's Analytics June 2009 Zn-65 in AP result of 137 pCi/L was higher than the known value of 101 pCi/L, resulting in a found to known ratio of 1.36. NCR 09-23 was initiated to investigate this failure. The failure appears to be a result of a slightly high bias on Detector 7. A recount on Detector 17 resulted in a Zn-65 result of 101 pCi/L. The detector has been tagged out-of-service until a recalibration can be performed.
Detector 7 is not used for client samples.
For the secondary laboratory, Environmental, Inc., 11 out of 14 analytes met the specified acceptance criteria. Four samples did not meet the specified acceptance criteria for following reasons:
- 1. Environmental Inc.'s ERA April 2009 Cs-1 37 in water result of 147.7 pCi/L exceeded the lower control limit of 151.0 pCi/L. All gamma emitters showed a low bias. A large plastic burr found on the base of the Marinelli kept the beaker from sitting directly on the detector. Recounting in a different beaker gave an acceptable result of 155.33 +/- 14.55 pCi/L.
- 2. Environmental Inc.'s ERA April 2009 H-3 in water result of 22819 pCi/L exceeded the upper control limit of 22300 pCi/L. A recount of the original vials averaged 23,009 pCi/L. Reanalysis results were acceptable at 19,170 pCi/L. No cause could be found for the failure.
- 3. Environmental Inc.'s MAPEP January 2009 Sr-90 in AP result of 0.93 exceeded the upper control limit of 0.83. Reanalysis results were acceptable at 0.54 +/- 0.12 Bq/filter. No cause could be found for the failure.
- 4. Environmental Inc.'s MAPEP July 2009 Sr-90 in soil result of 310.5 Bq/kg exceeded the lower control limit of 319 Bq/kg. Reanalysis results were acceptable at 363.3 Bq/kg. Incomplete separation of strontium from calcium could result in a higher recovery percentage and consequently lower reported activity.
The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

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/I of each other. The data reported were well within the historical range.

APPENDIX F ERRATA DATA
2007
- 2. Teledyne Brown Engineering's MAPEP Series 15 January 2006 Sr-90 in vegetation result of 2.22 Bq/kg exceeded the upper acceptance range of 2.029 Bq/kg. The samples were analyzed in triplicate and the results averaged. One high result of 2.43 Bq/kg biased the submitted results on the high side. TBE was unable to determine the cause for the higher result. The Sr-90 in vegetation results for MAPEP Series 14 and MAPEP Series 16 were acceptable. No client samples were analyzed during the MAPEP Series 14 time period.
- 3.
Teledyne Brown Engineering's MAPEP Series 15 January 2006 Pu-238 and Pu-239/240 in vegetation result of 2.22 Bq/kg failed the required acceptance ranges. TBE was evaluating the current preparation method for vegetation samples, which proved insufficient for the analyses. TBE does not perform isotopic Pu on client's vegetation samples.
For the secondary laboratory, 20 out of 25 analytes met the specified acceptance criteria. Seven samples did not meet the specified acceptance criteria for the following reasons:
- 1.
Environmental Inc.'s ERA November 2006 water 1-131 result of 28.4 pCi/L exceeded the upper control limit of 27.3 pCi/L. The reported result was an average of three analyses, results ranged from 25.36 pCi/L to 29.23 pCi/L. A fourth analysis was performed, with a result of 24.89 pCi/L.
- 2.
Environmental Inc.'s MAPEP January 2006 vegetation Pu-238 result of 0.08 Bq/sample exceeded the lower control limit of 0.10 Bq/sample due to incomplete dissolution of the sample.
- 3.
Environmental Inc.'s MAPEP January 2006 air particulate Pu-238 result of 0.03 Bq/sample exceeded the lower control limit of 0.05 Bq/sample due to incomplete dissolution of the sample.
- 4.
Environmental Inc.'s MAPEP January 2006 soil Pu-238, Pu-239/240, U-233/234 and U-238 results of 14.6, 14.6, 13.5 and 15.4 Bq/kg, respectively, exceeded the lower control limits of 42.81, 32.09, 25.9 and 27.2 Bq/kg, respectively, due to incomplete dissolution of the sample.
The Inter-Laboratory Comparison Program provides evidence of "in control" 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 Peach Bottom Atomic Power Station (PBAPS) by Exelon Nuclear covers the period 01 January 2009 through 31 December 2009. This evaluation involved numerous station personnel and contractor support personnel. At Peach Bottom Atomic Power Station, 14 permanent groundwater monitoring wells were installed in 2006. Of these monitoring locations, none were assigned to the station's Radiological Environmental Monitoring Program (REMP). This is the third in a series of annual reports on the status of the Radiological Groundwater Protection Program (RGPP) conducted at Peach Bottom Atomic Power Station. This report covers groundwater and seep water samples, collected from the environment, both on and off station property in 2009. During that time period, 596 analyses were performed on 529 samples from 44 locations. Phase 1 of the monitoring was part of a comprehensive study initiated by Exelon to determine whether groundwater or surface water at and in the vicinity of Peach Bottom Atomic Power Station had been adversely impacted by any releases of radionuclides. Phase 1 was conducted by Conestoga Rovers and Associates (CRA) and the conclusions were made available to state and federal regulators as well as the public on an Exelon web site http://www.exeloncorp.com/ourcompanies/powerqen/nuclear/Tritium.htm].
Phase 2 of the RGPP was conducted by Exelon corporate and station personnel to initiate follow up of Phase 1 and begin long-term monitoring at groundwater and surface water locations selected during Phase 1. All analytical results from Phase 2 monitoring are reported herein.
In assessing all the data gathered for this report, it was concluded that the operation of Peach Bottom Atomic Power Station had no adverse radiological impact on the environment, and there are no known active releases into the groundwater at Peach Bottom Atomic Power Station.
Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) as specified in the Offsite Dose Calculation Manual (ODCM) in any of the groundwater or surface water samples. In the case of tritium, Exelon specified that it's laboratories achieve a lower limit of detection 10 times lower than that required by federal regulation.
Strontium-90 was not detected in any of the samples and the required LLD of 2.0 pCi/liter was met except for one sample had a Sr-90 MDA of 3.3 pCi/I (Table B-1.1, Appendix B).
Tritium was detected in 7 groundwater locations at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission Reporting Limit) of 20,000 pCi/L. Low levels of tritium were detected at concentrations greater than the LLD 1
of 200 pCi/L in 18 of 42 groundwater and seep water monitoring locations. The tritium concentrations ranged from 146 +/- 85 pCi/L to 110,000 +/- 11,300 pCi/L.
Tritium was not detected in surface water. Based on the sample data, tritium is not migrating off the station property at detectable concentrations.

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.
This report covers those analyses performed by Teledyne Brown Engineering (TBE) on samples collected in 2009.
A.
Objective of the RGPP The long-term objectives of the RGPP are as follows:
- 1. Identify suitable locations to monitor and evaluate potential impacts from station operations before significant radiological impact to the environment and potential drinking water sources.
- 2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up-to-date knowledge of flow patterns on the surface and shallow subsurface.
- 3. Perform routine water sampling and radiological analysis of water from selected locations.
- 4. Report new leaks, spills, or other detections with potential radiological significance to stakeholders in a timely manner.
- 5. Regularly assess analytical results to identify adverse trends.
- 6. Take necessary corrective actions to protect groundwater resources.

Program Description
- 1.
Sample Collection Sample locations can be found in Table A-1 and Figures A-1 and A-2, Appendix A.
Groundwater and Surface Water Samples of water are collected, managed, transported and analyzed in accordance with approved procedures following EPA methods. Both groundwater and surface water are collected.
Sample locations, sample collection frequencies and analytical 5
frequencies are controlled in accordance with approved station procedures. Contractor and/or station personnel are trained in the collection, preservation management, and shipment of samples, as well as in documentation of sampling events. Analytical laboratories are subject to internal quality assurance programs, industry cross-check programs, as well as nuclear industry audits.
Station personnel review and evaluate all analytical data deliverables as data are received.
Analytical data results are reviewed by both station personnel and an independent hydro geologist for adverse trends or changes to hydrogeologic conditions.

Characteristics of Tritium (H-3)
Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called "tritiated water." The chemical properties of tritium are essentially those of ordinary hydrogen.
Tritiated water behaves the same as ordinary water in both the environment and the body. Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Tritium is excreted primarily through urine with a clearance rate characterized by an effective biological half-life of about 14 days. Within one month or so after ingestion, essentially all tritium is cleared. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period.
Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotopes lithium-7 and/or boron-1i 6're activated to produce tritium.
Like normal water, tritiated water is colorless and odorless. Tritiated water behaves chemically and physically like non-tritiated water in the subsurface, and therefore tritiated water will travel at the same velocity as the average groundwater velocity.
Tritium has a half-life of approximately 12.3 years. It decays spontaneously to helium-3 (He-3). This radioactive decay releases a beta particle (low-energy electron). The radioactive decay of tritium is the source of the health risk from exposure to tritium. Tritium is one of the least dangerous radionuclides because it emits very weak radiation and leaves the body relatively quickly. Since tritium is almost always found as 6
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.

Program Description A.
Sample Analysis This section describes the general analytical methodologies used by TBE and EIML to analyze the environmental samples for radioactivity for the Peach Bottom Atomic Power Station RGPP in 2009.
In order to achieve the stated objectives, the current program includes the following analyses:
- 1.
Concentrations of gamma emitters in groundwater and surface water.
- 2.
Concentrations of strontium-90 in groundwater and surface water.
- 3.
Concentrations of tritium in groundwater and surface water.
B.
Data Interpretation The radiological data collected prior to Peach Bottom Atomic Power Station becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, Peach Bottom Atomic Power Station was considered operational at initial criticality. Several factors were important in the interpretation of the data:
- 1.
Lower Limit of Detection The lower limit of detection (LLD) is a minimum sensitivity value that must be achieved routinely by the analytical parameter.
- 2.
Laboratory Measurements Uncertainty The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the measurement value.
Statistically, the exact value of a measurement is expressed as a range with a stated level of confidence. The convention is to report results with a 95% level of confidence. The uncertainty comes 7
from calibration standards, sample volume or weight measurements, sampling uncertainty and other factors. Exelon reports the uncertainty of a measurement created by statistical process (counting error) as well as all sources of error (Total Propagated Uncertainty or TPU). Each result has two values calculated. Exelon reports the TPU by following the result with plus or minus +/- the estimated sample standard deviation, as TPU, that is obtained by propagating all sources of analytical uncertainty in measurements.
Analytical uncertainties are reported at the 95% confidence level in this report for reporting consistency with the AREOR.
Gamma spectroscopy results for each type of sample were grouped as follows:
For groundwater and surface water 13 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, 1-131, Cs-134, Cs-137, Ba-140 and La-140 were reported.
C.
Background Analysis A pre-operational radiological environmental monitoring program (pre-operational REMP) was conducted to establish background radioactivity levels prior to operation of the Station. The environmental media sampled and analyzed during the pre-operational REMP were atmospheric radiation, fall-out, domestic water, surface water, marine life, and foodstuffs. The results of the monitoring were detailed in the report entitled, Peach Bottom Atomic Power Station, Environs Radiation Monitoring Program, Preoperational Summary Report units 2 and 3, September 1970- August 1973, January 1974 and Peach Bottom Atomic Power Station, Environs Radiation Monitoring Program, Preoperational Summary Report units 2 and 3, June 1977.
The pre-operational REMP contained analytical results from samples collected from the surface water, discharge, well and rain water.
The pre-operational REMP (Units 2 and 3) analytical results from samples collected from surface water and drinking water wells indicate that tritium was detected in both surface water and drinking water samples. Tritium concentrations in surface water ranged from non-detect at the lower limit of detection (LLD) of 80 picoCuries per liter (pCi/L) to 1,300 pCi/L over the 3-year monitoring period (1970-1973). Tritium concentrations in drinking water ranged from non-detect at the LLD of 80 pCi/L to 790 +/- 90 pCi/L.
Gross beta analytical results in surface water ranged from 1.2 +/- 1.1 pCi/L 8
to 9.6 +/- 3.1 pCi/L. Gamma spectrometry analytical results in surface water and drinking water were found very sporadically and at concentrations nominally that exceed their respective LLD.
1.
Background Concentrations of Tritium The purpose of the following discussion is to summarize background measurements of tritium in various media performed by others. Additional detail may be found by consulting references (CRA 2006).
- a.
Tritium Production Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man-made) sources. In the upper atmosphere, "Cosmogenic" tritium is produced from the bombardment of stable nuclides and combines with oxygen to form tritiated water, which will then enter the hydrologic cycle. Below ground, "lithogenic" tritium is produced by the bombardment of natural lithium present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant uranium and thorium. Lithogenic production of tritium is usually negligible compared to other sources due to the limited abundance of lithium in rock. The lithogenic tritium is introduced directly to groundwater.
A major anthropogenic source of tritium and strontium-90 comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased significantly during the 1950s and early 1960s, and later with additional testing, resulting in the release of significant amounts of tritium to the atmosphere. The Canadian heavy water nuclear power reactors, other commercial power reactors, nuclear research and weapons production continue to influence tritium concentrations in the environment.
- b.
Precipitation Data Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides. Two publicly available databases that provide tritium concentrations in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet database. GNIP provides tritium precipitation concentration 9
data for samples collected world wide from 1960 to 2006.
RadNet provides tritium precipitation concentration data for samples collected at stations through out the U.S. from 1960 up to and including 2006. Based on GNIP data for sample stations located in the U.S. Midwest, tritium concentrations peaked around 1963. This peak, which approached 10,000 pCi/L for some stations, coincided with the atmospheric testing of thermonuclear weapons. Tritium concentrations in surface water showed a sharp decline up until 1975 followed by a gradual decline since that time. Tritium concentrations have typically been below 100 pCi/L since around 1980.
Tritium concentrations in wells may still be above the 200 pCi/L 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 Surface water level measurements were collected at the surface water monitoring locations during the groundwater level measurement event. The purpose of the surface water monitoring was to provide surface water elevation data to evaluate the groundwater/surface water interaction at the Station.
The USEPA RadNet surface water data typically has a reported 'Combined Standard Uncertainty' of 35 to 50 pCi/L.
According to USEPA, this corresponds to a +/-70 to 100 pCi/L 95% confidence bound on each given measurement.
Therefore, the typical background data provided may be subject to measurement uncertainty of approximately +/- 70 to 100 pCi/L.
The radio-analytical laboratory is counting tritium results to an Exelon specified LLD of 200 pCi/L. Typically, the lowest positive measurement will be reported within a range of 40 -
240 pCi/L or 140 +/- 100 pCi/L. Clearly, these sample results cannot be distinguished as different from background at this concentration.

Results and Discussion A.
Groundwater Results Groundwater Samples were collected from on and off-site wells throughout the year in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.
Tritium Samples from 44 locations were analyzed for tritium activity (Table B-1.1, Appendix B). Tritium values ranged from the detection limit to 110,000 pCi/I. Within the station boundary, concentrations of tritium in shallow groundwater reached 110,000 pCi/L. The existing wells at or near the owner-controlled boundary showed no tritium.
The location most representative of potential offsite user of drinking water is less than the LLD. (Table B-1.1, Appendix B).
Strontium Strontium-90 was not detected in any of the samples and the required LLD of 2.0 pCi/liter was met except for one sample had a Sr-90 MDA of 3.3 pCi/I (Table B-1.1, Appendix B).
Gamma Emitters No power-production gamma emitters were detected in any of the samples. Naturally occurring, berillyum-7 was not detected in any samples.
Naturally occurring, potassium-40 was detected in two of 33 samples and the concentration ranged from 86.of 3,540 pCi/liter. No other gamma emitting nuclides were detected. (Table B-1.2, Appendix B).
B.

Leaks, Spills, and Releases A valve leak was identified in the Unit 3 Condensate Storage Tank moat on June 17, 2009. The valve packing was adjusted and the leak was stopped on June 18, 2009. The Unit 3 Yard Drain Sump tritium activity in May.2009 was 6,081 pCi/L. In December 2009, the tritium activity in the Unit 3 Yard Drain Sump was reduced to 254 pCi/L. This leak was a potential contributor to activity found in well MW-PB-4, see investigation of well MW-PB-4 in section G.
F.
Trends A tritium plume has been identified northeast of the Unit 3 Turbine Building. The highest tritium concentration is in wells MW-PB-25 and 26.
The plume extends eastward toward well MW-PB-4. The plume is bounded on the north by wells MW-PB-1 2 and MW-PB-22. The plume is bounded on the south by wells MW-PB-20 and MW-PB-21. Wells, MW-PB-4, 12, and 19 through 26, are sampled and analyzed weekly for 12
tritium. All wells had a decreasing tritium activity trend as of the end of December 2009.
G.
Investigations MW-PB-4 Investigation In May 2009, an overburden well, MW-PB-23, was installed east of the Unit 3 Condensate Storage Tank (CST). The well is 16.5' bgs. This well is dry and has not produced a sample for analysis. The purpose of this well is to assess groundwater tritium activity in the area east of the Unit 3 CST.
In July of 2009,Geo-probe or Vacuum Hole (VH) wells, VH-PB-3, VH-PB-4 and VH-PB-5 were installed on the northeast side of the Unit 3 Turbine Building. Tritium activity in these wells ranged from 34,100 to 110,000 pCi/L. A voluntary, special report was submitted in accordance with NEI 07-07, Industry Ground Water Protection Initiative - Final Guidance Document.
Tritium activity in monitoring well MW-PB-4 was 3,040 pCi/L at the beginning of 2009. The tritium activity fluctuated between 945 and 4,020 pCi/L through 2009. Tritium activity at the end of 2009 was 1,060 pCi/L.
In August 2009, monitoring wells MW-PB-24 (8' bgs), MW-PB-25 (6.5' bgs) and MW-PB-26 (20.5' bgs) were installed northeast of the Unit 3 Turbine building. These overburden wells replaced VH-PB-2, VH-PB-4 and VH-PB-5 respectively. The purpose of these wells is to assess groundwater tritium concentrations in the overburden from potential sources in the Unit 3 Turbine Building. Groundwater in the area of the wells has a preferred flow path east along circulating water and storm drain piping towards MW-PB-4.
H.
Actions Taken
- 1. Compensatory Actions Since the installation of MW-PB-24, 25 and 26, wells MW-PB-4, 12, and 19 through 26, were sampled and analyzed weekly for tritium.
Intake and discharge canal water and domestic water are also sampled at an increased frequency. There has been no detectable tritium in the intake and discharge canal water and domestic water samples.
13
- 2. Installation of Monitoring Wells Four new monitoring wells were installed in 2009. MW-PB-23, east of the Unit 3 CST, and MW-PB-24, 25 and 26, northeast of the Unit 3 Turbine building. All wells are overburden wells with depths bgs of 6.5' to 20.5'.
- 3. Actions to Recover/Reverse Plumes None.
Deviations Three samples were not analyzed for Fe-55, 4 samples were not analyzed for Sr-90 and 6 samples were obtained once in 2009, when the requirement is for 2 tritium analyses per year. These analyses are performed by an offsite vendor. During 2009, 596 analyses were performed on 529 samples.
Specifics:
Fe-55 analysis was missed on well MW-B-4, 12, 13. These wells were last sampled and analyzed for Fe-55 in 2007 with no Fe-55 detected.
Sr-90 North Substation, South substation, Salt washdown area, and the Hazardous Waste Staging Area. These sample points were last sampled and analyzed for Sr-90 in 2008 with Sr-90 detected.
Sample points MW-PB-13, North substation, South substation, Salt washdown, Hazardous Waste staging area and SP-PB-3 were not sampled and analyzed for tritium in the second half of 2009.
