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 2011 through 31 December 2011. During that time period, 1,193 analyses were performed on 935 samples.

On March 11, 2011 an earthquake off the Japanese islands produced a massive

.tsunami that caused a nuclear accident at four of the six Fukushima Daiichi reactors. In planning for the potential radioactive plume reaching the United States, Exelon Nuclear increased the sampling frequency and added additional analyses of select media from pathways that were expected to be the most sensitive to any increase in ambient radiation levels. Low level 1-131 analyses and gamma spectroscopy analyses were performed on air particulates, air iodine, and milk, as appropriate.

The resulting radioactive plume was first detected in the environs of Peach Bottom Atomic Power Station on March 22, 2011. The final date of positive detection was April 18, 2011. The radionuclide identified was Iodine-1 31.

Maximum activity levels found by media were 94 E-3 pCi/m 3 for air iodine and 6.9 pCi/L for milk. Samples collected were compared to offsite control locations to verify that these positive detections were not attributable to licensed activities.

All other radionuclides analyzed were below the MDC (Minimum Detectable Concentration).

The radioactive half-life of 1-131 is about 8 days. This short half-life allowed the affects of this radioactive plume to subside over about 4 weeks. As of April 18, 2011 no further impacts from the Fukushima Daiichi accident were evident.

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. Tritium was not detected in drinking water.

Precipitation samples were analyzed under the RGPP (Radiological Groundwater Protection Program) in 2011. 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-1 37 activity was found at all 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 affects 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 with the exception of 11 samples which were positive for 1-131. These positive results are directly attributed to the Fukushima event in March of 2011.

Examination of the terrestrial environment was accomplished by analyzing milk and food product samples. Milk samples were analyzed for low level concentrations of lodine-131 and gamma emitting nuclides. Four milk samples were positive for 1-131 in the weeks immediately following the Fukushima event.

These positive results are directly attributed to the Fukushima event. 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. 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 confirm that the Independent Spent Fuel Storage Installation (ISFSI) had no 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 Annual Radiological Groundwater Protection Program Report (ARGPPR) is found in Appendix G.

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 1,170 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), Mirion Technologies, and Environmental Inc. (Midwest Labs) on samples collected during the period 01 January 2011 through 31 December 2011.

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.

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 2011. 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 (1 LL and 1MM) and drinking water from three locations (1 3B, 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, 1 B, 4M) were collected monthly. Fish samples comprising the flesh from two groups:

Bottom Feeder (channel catfish, flathead catfish, and quillback) and Predator (smallmouth bass and largemouth bass) were collected semiannually from two locations (4 and 6; 6 is the control). Sediment samples composed of recently deposited substrate were collected semiannually at three locations (4J, 4T and 6F; 6F is the control).

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on air particulate, and airborne iodine samples. Air particulate and air iodine samples were collected and analyzed weekly from five locations (1B, 1C, 1Z, 3A, and 5H2; 5H2 is the control). 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.

Terrestrial Environment The terrestrial environment was evaluated by performing radiological analyses on milk and food product samples. Milk samples were collected biweekly at five locations (J, R, S, U and V; V is the control) from April through November and monthly from December through March. Six additional locations (C, D, E, L, P and W; C and E are the controls) were sampled quarterly. 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 two locations (1Q, and 55; 55 is the control) in May through 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 20 locations (1A, 1B, 1C, 1D, 1E, 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

-,6-

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, and 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 2011. 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 drinking water, surface water, 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.

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

The minimum detectable concentration (MDC) is defined similarly as above for LLD; however the MDC is an after-the-fact estimate vice a before-the-fact as in LLD.

2.

Net Activity Calculation and Reportingq of Results Net activity for a sample is 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 affecting a negative number. An MDC is 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-1 34, and Cs-137 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-134, and Cs-137 were reported.

For milk five nuclides, K-40, Cs-1 34, Cs-1 37, Ba-140, and La-140 were reported.

For food product eight nuclides, Be-7, K-40, Mn-54, Co-58, Co-60, 1-131, Cs-1 34, 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 2011 the PBAPS REMP had a sample collection recovery rate of better than 99%. The exceptions to this program are listed below:

1.

Week 11: The Station 1C air sampler was not running at the time of collection 3/17/11. The power outlet was found to be faulty. The outlet was replaced and the sampler restarted on 3/21/11. Due to inadequate air volume, samples were considered invalid. Although the samples were sent to the laboratory, the laboratory was directed not to analyze them. IR# 1227440.

2.

Week 13: The particulate and iodine samples collected during the collection period 3/16/11-3/23/11 were lost (i.e. FedEx is still unable to locate them). The envelope was found open and the samples were not enclosed when the package was received at the laboratory. IR#

1227440.

3.

Week 22: For the May 2011 collection period, only one of three samples was available from Indicator Station 1Q and none were available at Indicator Station 2B (no garden planted). However, two of three samples were available from Control Station 55. One of these two samples was split with the Pennsylvania Department of Environmental Protection (PADAP). IR# 1227440.

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 Starting in May, 2011, 1-131 is now being analyzed in drinking water and surface water by the low level method to detect down to 1.0 pCi/L.

IV.

Results and Discussion A.

Aquatic Environment 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.

Iodine Starting in May, 2011, monthly samples from both locations were analyzed for 1-131. All results were less than the MDC (Table C-1.2, Appendix C).

Gamma Spectrometry Samples from both locations were analyzed for gamma emitting nuclides (Table C-1.3, 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). Two locations (13B and 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 29 of 36 samples. The values ranged from 1.8 to 9.2 pCi/I. Concentrations detected were generally below those detected in previous years.

Tritium Monthly samples from three locations were composited quarterly and analyzed for tritium activity (Table C-I1.2, Appendix C). Tritium activity was not detected in any samples.

Iodine Starting in May 2011, monthly samples from three locations were analyzed for 1-131 (Table C-I1.3, Appendix C). All results were less than the MDC.

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

3.

Precipitation Precipitation samples were analyzed under the RGPP in 2011.

4.

Fish Fish samples comprised of bottom feeder and predator 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 Spectrometry 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 2,950 to 3,880 pCi/kg wet and was consistent with levels detected in previous years. No Peach Bottom fission or activation products were found in 2011. Historical levels of Cs-1 37 are shown in Figure C-2, 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 Soectrometrv Sediment samples from all three locations were analyzed for gamma emitting nuclides (Table C-IV. 1, Appendix C). Potassium-40 was found in all locations and ranged from 14,700 to 18,700 pCi/kg dry.

The fission product Cs-1 37 was detected in three of six samples and ranged from 104 to 185 pCi/kg. The activity of Cs-137 detected was consistent with those detected in the preoperational years. Historical levels of Cs-137 are shown in Figure C-3, Appendix C. No other Peach Bottom fission or activation products were found.

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 6 to 39 E-3 pCi/m3, with a mean of 19 E-3 pCi/m3. The results from the Intermediate Distance location (Group II) ranged from 9 to 32 E-3 pCi/m3 with a mean of 20 E-3 pCi/m3. The results from the Distant location (Group Ill) ranged from 8 to 34 E-3 pCi/m3 with a mean of 17 E-3 pCi/m3. A comparison of the weekly mean values for 2011 indicate no notable differences among the three groups (Figure C-5, Appendix C). In addition, a comparison of the 2011 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 all samples. These values ranged from 62 to 103 E-3 pCi/m 3. All other nuclides were less than the MDC.

Additional sampling occurred in the weeks immediately following the Fukushima event. Two samples were positive for naturally occurring Be-7. The concentrations ranged from 295 to 338 E-3 pCi/m 3. All other nuclides were less than the MDC and all required LLDs were met.

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, with the exception of 11 samples which were positive for 1-131. These results are directly attributed to the Fukushima event in March of 2011.

2.

Terrestrial

a.

Milk Samples were collected from five locations (J, R, S, U and V) 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-131 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, with the exception of 4 samples which were positive for 1-131. The concentrations ranged from 0.8 to 6.9 pCi/l. These results are directly attributed to the Fukushima event in March of 2011. In the weeks immediately following the Fukushima Event in March of 2011, additional sampling was performed. All results were less than the MDC and all required LLDs were met.

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 968 to 1,550 pCi/I. All other nuclides were less than the MDC. In the weeks immediately following the Fukushima Event in March of 2011, additional sampling was performed.

Naturally occurring K-40 was detected in two samples. The concentrations ranged from 1,230 to 1,280 pCi/L. All other results were less than the MDC and all required LLDs were met. Comparison of the 2011 Cs-1 37 milk data with previous years data indicate no effects from the operation of PBAPS (Figure C-6, Appendix C).

b.

Food Products Food product samples were collected at two locations (1Q, and 55) when available. Of these locations, 1 Q and 55 could be affected by Peach Bottom's effluent releases. The following analysis was performed:

Gamma Spectrometry Each food product sample from locations 1Q and 55 was analyzed for concentrations of gamma emitting nuclides (Table C-VIII.1, Appendix C).

Naturally occurring Be-7 activity was found in 13 of 26 samples and ranged from 162 to 2,610 pCi/kg wet.

Potassium-40 activity was found in all samples and ranged from 2,220 to 10,500 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 CI-X.3 and Figure C-7, Appendix C.

All TLD measurements were below 10 mR per standard month, with a range of 2.1 to 8.2 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. During 2011, a total of 5 TN-68 casks, each loaded with 68 fuel bundles, were added to 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-ISFSI loading (Figure C-8, Appendix C). Location 2B, which represents the nearest residence, showed no effect in dose rate from the ISFSI 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 2011 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.

Errata Data The Annual Radiological Environmental Operating Report #68 January 1, 2010 through December 31, 2010

1. A Program Exception for the 2010 AEROR report should have been reported regarding an LLD not obtained for Station 13B Drinking Water sample for 7/6/2010. The LLD was reported as "<20 pCi/ L" in the sample results because the sample volume was insufficient to obtain the required <15 pCi/ L LLD for Exelon Nuclear Mid-Atlantic sites. This exception should have been reported in the 2010 AEROR. This issue was documented in IR# 1230988. The current required LLD for drinking water is 1 pCi/L.
2. Dose Calculations to the Public The noble gas doses were recalculated using the ODCM Revision 13 x/Q (Dispersion Factor) values. The iodine-131, iodine-133, tritium, carbon-14 and particulate doses were recalculated using the ODCM Revision 13 dose factors for ingestion, inhalation and ground plane pathways. The corrected data are contained in Appendix F "Errata Data".

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 Eckert & Ziegler 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 The Environmental Resource Associates' evaluation report provides an acceptance range for control and warning limits with associated flag values. The Environmental Resource Associates' acceptance limits are established per the United States Environmental Protection Agency (USEPA), National Environmental Laboratory Accreditation Conference (NELAC),

state specific performance testing program requirements or ERA's standard operating procedure 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, 14 out of 18 analytes met the specified acceptance criteria. Three analytes did not meet the specified acceptance criteria for the following reason:

1. Teledyne Brown Engineering's Analytics March 2011 Cr-51 in milk result of 398 pCi/L was higher than the known value of 298 pCi/L, resulting in a found to known ratio of 1.34. NCR 11-13 was initiated to investigate this failure. There was a slightly high bias in all the gamma activities. The June gamma results in milk did not show a high bias. No further action was required.
2. Teledyne Brown Engineering's ERA May 2011 Gross Alpha in water result of 64.1 pCVL was higher than the known value of 50.1 pCVL, which exceeded the upper control limit of 62.9 pCVL. NCR 11-08 was initiated to investigate this failure. The solids on the planchet exceeded 100 mg, which was beyond the range of the efficiency curve.

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

3. Teledyne Brown Engineering's ERA November 2011 Sr-89 in water result of 81.0 pCVL was higher than the known value of 69.7 pCi/L, which exceeded the upper control limit of 77.9 pCi/L. NCR 11-16 was initiated to investigate this failure. The TBE reported value to known ratio of 1.16 fell within the acceptable range of + 20%, which TBE considers acceptable.
4. Teledyne Brown Engineering's MAPEP March 2011 Sr-90 in soil, air particulate, and vegetation results were not reported. MAPEP evaluates analytes not reported as failures. NCR 11-11 was initiated to investigate these failures. No further action was required.

For the secondary laboratory, Environmental, Inc., 12 out of 14 analytes met the specified acceptance criteria.

1. Environmental Inc.'s ERA October 2011 Cs-134 in water result of 38.8 pCVL was higher than the known value of 33.4 pCVL, which exceeded the upper control limit of 36.7 pCVL. The sample was reanalyzed. The reanalyzed result of 32.9 was acceptable.
2. Environmental Inc.'s MAPEP February 2011 Sr-90 in air particulate result of 1.89 Bq/sample was higher than the known value of 1.36 Bq/sample, which exceeded the upper control limit of 1.77 Bq/sample. No errors were found in the calculation or procedure.

The reanalyzed result of 1.73 Bq/sample was acceptable.

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

The Inter-Laboratory Comparison Program provides evidence of "in 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 2011 through 31 December 2011. This evaluation involved numerous station personnel and contractor support personnel. At Peach Bottom Atomic Power Station, there are 31 permanent groundwater monitoring wells. Installation of the wells began in 2006. Of these monitoring locations, none were assigned to the station's Radiological Environmental Monitoring Program (REMP). This is the fifth 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 on station property in 2011. During that time period, 1,322 analyses were performed on more than 446 samples from 40 locations. These 40 locations include 27 groundwater monitoring wells, 3 surface water sample points, 3 groundwater seeps and 2 yard drain sumps (groundwater), and 5 precipitation water sampling points. Phase 1 of the monitoring was part of a comprehensive study initiated by Exelon to determine whether groundwater or surface water 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. 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 its 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 1.0 pCi/liter was met (Table B-1. 1, Appendix B).

Precipitation water samples have been moved from the environmental program to the RGPP program.

1 G-4

Tritium was detected in one groundwater location 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 of 200,pCi/L in 13 of 27 groundwater and seep water monitoring locations. The tritium concentrations ranged from 208 +/- 120 pCi/L to 67,500 + 6,780 pCi/L.

Tritium was not detected at concentrations greater than the LLD of 200 pCi/L in any surface water or precipitation water sample locations. Based on the sample data, tritium is not migrating off the station property at detectable concentrations.

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during 2011. This is the second year these analyses were performed as part of the RGPP for Peach Bottom to establish baseline levels. Gross Alpha (dissolved) was detected in six of 25 groundwater locations analyzed. The concentrations ranged from 1.1 to 17.3 pCi/L. Gross Alpha (suspended) was detected in 10 of 25 groundwater locations analyzed. The concentrations ranged from 1.0 to 12.2 pCi/L. Gross Beta (dissolved) was detected in 23 of 25 groundwater locations analyzed. The concentrations ranged from 1.2 to 34.3 pCi/L. Gross Beta (suspended) was detected in 10 of 25 groundwater locations analyzed. The concentrations ranged from 0.8 to 11.4 pCi/L. The activity detected is consistent with historical levels.

Hard-To-Detect analyses were performed on a select group of groundwater and surface water locations to establish baseline levels. The analyses for groundwater included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-233/234, U-235, and U-238. The isotopes of U-233/234 and U-238 were detected in three of eight groundwater monitoring locations. The U-233/234 concentrations ranged from 0.83 to 5.78 pCi/L and the U-238 concentrations ranged from 0.39 to 2.46 pCi/L. No plant produced radionuclides were detected.

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 2011.

A.

Objective of the RGPP The objectives of the RGPP are as follows:

1. Ensure that the site characterization of geology and hydrology provides an understanding of predominant ground water gradients based upon current site conditions.
2. Identify site risk based on plant design and work practices.
3. Establish an on-site ground water monitoring program to ensure timely detection of inadvertent radiological releases to ground water.
4. Establish a remediation protocol to prevent migration of licensed material off-site and to minimize decommissioning impacts.
5. Ensure that records of leaks, spills, remediation efforts are retained and retrievable to meet the requirements of 10 CFR 50.75(g).
6. Conduct initial and periodic briefings of their site specific Groundwater Protection Initiative (GPI) program with the designated State/Local officials.

3 G-6

7. Make informal communication as soon as practicable to appropriate State/Local officials, with follow-up notifications to the NRC, as appropriate, regarding significant "on-site leaks/spills into ground water and on-site or off-site water sample results exceeding the criteria in the REMP as described in the OCDM/ODAM.
8. Submit a written 30-day report to the NRC for any water sample result for on-site ground water that is or may be used as a source of drinking water that exceeds any of the criteria in the licensee's existing REMP/ODCM for 30-day reporting of off-site water sample results.
9. Document all on-site ground water sample results and a description of any significant on-site leaks/spills into ground water for each calendar year in the Annual Radiological Environmental Operating Report (AREOR) for REMP or the Annual Radioactive Effluent Release Report (ARERR) for the RETS as contained in the appropriate Site reporting procedure.
10. Perform a self-assessment of the GPI program.
11. Conduct a review of the GPI program, including at a minimum the licensee's self assessments, under the auspices of NEI.

4 G-7

Groundwater and Surface Water Samples of water are collected, managed, transported and analyzed in accordance with approved procedures. Both groundwater and surface water are collected. Sample locations, sample collection frequencies.and analytical frequencies are controlled in accordance with approved station procedures.

Contractor and/or station personnel are trained in the collection, preservation management, and shipment of samples, as well as in documentation of sampling events. 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-10 are 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.

5 G-8

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 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 2011.

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 in groundwater.

3.

Concentrations of tritium in groundwater and surface water.

4.

Concentrations of 'hard-to-detect' isotopes (Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-233/234, U-235, U-238, Fe-55 and Ni-63) in groundwater. These analyses are required based on tritium results.

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 6

G-9

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 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 12 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 7

G-1O

collected from the surface water, discharge, well and rain water.

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 data for samples collected world wide from 1960 to 2006.

RadNet provides tritium precipitation concentration data for 8

G-11

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-site wells throughout the year in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.

Tritium Samples from 39 locations were analyzed for tritium activity (Table B-I.1, Appendix B). Tritium values ranged from the detection limit to 67,500 pCi/I. Within the station boundary, concentrations of tritium in shallow groundwater reached 67,500 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 1.0 pCi/liter (Table B-1.1, Appendix B).

Gross Alpha and Gross Beta (dissolved and suspended)

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during 2011. Gross Alpha (dissolved) was detected in six of 25 groundwater locations analyzed. The concentrations ranged from 1.1 to 17.3 pCi/L. Gross Alpha (suspended) was detected in 10 of 25 groundwater locations analyzed. The concentrations ranged from 1.0 to 12.2 pCi/L. Gross Beta (dissolved) was detected in 23 of 25 groundwater locations analyzed. The concentrations ranged from 1.2 to 34.3 pCi/L. Gross Beta (suspended) was detected in 10 of 25 groundwater locations analyzed. The concentrations ranged from 0.8 to 11.4 pCi/L. The activity detected is naturally occurring and the levels are considered to be background.

10 G-13

Hard-To-Detect Hard-To-Detect analyses were performed on a select group of groundwater and surface water locations to establish baseline levels. The analyses for groundwater included Fe-55, Ni-63, Am-

.241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-233/234, U-235, and U-238. The isotopes of U-233/234 and U-238 were detected in three of eight groundwater monitoring locations. The U-233/234 concentrations ranged from 0.83 to 5.78 pCi/L and the U-238 concentrations ranged from 0.39 to 2.46 pCi/L. The activity detected is naturally occurring and the levels are considered to be background (Table B-1.3, Appendix B).

Gamma Emitters No power-production gamma emitters were detected in any of the samples (Table B-1.2, Appendix B).

B.

Surface Water Results Surface Water Samples were collected from surface water locations throughout the year in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.

Tritium Samples from three locations were analyzed for tritium activity.

Tritium was not detected in any samples (Table B-11.1, Appendix B).

Gamma Emitters No power-production gamma emitters were detected in any of the samples. No other gamma emitting nuclides were detected (Table B-11.2, Appendix B).

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

F.

Leaks, Spills, and Releases There were no leaks, spills or releases of water containing licensed material to environment in 2011.

G.

Trends A tritium plume has been identified northeast of the Unit 3 Turbine Building. The highest tritium concentration is in well MW-PB-25. The plume extends eastward toward well MW-PB-4. The plume is bounded on the north by wells MW-PB-12 and MW-PB-22. The plume is bounded on the south by wells MW-PB-20 and MW-PB-21.

One sample from the Unit 2 Yard Drain Sump identified tritium at 249 +

119 pCi/L. All other samples from the Unit 2 and 3 Yard Drain Sump samples were less than the detection limit. The yard drain sump system collects groundwater that accumulates on the west side of the plant. A valve leak was repaired in the Unit 3 Condensate Storage Tank moat in July 2009. Tritium activity has decreased in the sumps since the repair.

Overall, there was a decreasing trend in tritium activity in samples obtained from groundwater monitoring wells in 2011.

12 G-15

H.

Investigations MW-PB-4 In 2006, monitoring wells MW-PB-1 through MW-PB-14 were installed.

Tritium activity. was detected: in MW-PB-4, located north of the Unit 3 Circulating Water Pump Structure and MW-PB-12, north of the Administration Building. Groundwater flow on site is from west to east.

Monitoring wells were installed to the west, southwest and northwest of monitoring wells MW-PB-4 and MW-PB-12. The wells with the highest tritium activity were the wells installed directly east and adjacent to the Unit 3 Turbine, wells MW-PB-24, 25, 26 and 27.

Investigation of potential sources identified that the likely source of groundwater contamination was due to degraded floor seams in the Unit 3 Turbine Moisture Separator area 116' elevation. Leaks internal to the building entered the groundwater through the degraded floor seams. The floor seams were repaired in August 2010. The floor in the Unit 3 Turbine Moisture Separator area 116' elevation was sealed and recoated in October 2011. Monitoring well activity has been decreasing since floor seam repairs were completed.

MW-PB-29, 30 and 31 An extent-of-condition inspection of the Unit 2 Turbine Moisture Separator area 116' elevation floor was performed in October 2010. Minor degradation of the floor seams was identified and repaired. In May 2011, monitoring wells MW-PB-29 and 30 were installed directly east of and adjacent to the Unit 2 Turbine Building; MW-PB-31 was installed southeast and adjacent to the Unit 2 Turbine Building. These wells were installed to determine if a condition existed east of the Unit 2 Turbine that was similar to the condition east of the Unit 3 Turbine Building.

Wells MW-PB-29, 30 and 31 were sampled a total of 24 times in 2011.

Tritium activity in the wells ranged from less than the LLD to 1,220 +/- 202 pCi/L. Samples from these wells were also analyzed for gamma emitting isotopes and hard to detect radionuclides. All results were less than the LLD for each isotope.

13 G-16

MW-PB-4, 24, 25, 26 and 27 Wells MW-PB-4, 24, 25, 26 and 27 are considered the wells of primary interest and were sampled on a frequency that ranged from weekly to monthly. Below are 2 tables. The first lists the highest tritium activity of the wells of primary interest and the date of the sampling. The second table lists the tritium activity of the wells from the last sampling of 2011.

The tritium activity is in pCi/L.

The most likely pathway for tritium to enter the groundwater has been determined to be leaks internal to the Unit 3 Turbine Building Moisture Separator 116', migrating through degraded floor seams. The floor seams were repaired and the entire floor was sealed and a coating applied during the refuel outage in the fall of 2011. The wells have been on a decreasing trend since these repairs were completed.

Actions Taken

1. Compensatory Actions Wells, MW-PB-4, 24, 25, 26 and 27 were sampled and analyzed for tritium on a weekly to monthly frequency. Wells MW-PB-21, 29, 30, and 31 were sampled and analyzed for tritium on a monthly to quarterly frequency. Wells MW-PB-12, 19, 20, 22 and 28 were sampled and analyzed on a weekly to quarterly frequency. Well sampling frequency varied based on tritium activity trends in the wells. All sample frequencies 14 G-17

were within frequencies established by station procedure. Well sampling frequency decreased with a decreasing overall trend in tritium activity.

Intake and discharge canal water and domestic water continued to be sampled at an increased frequency in 2011. Intake and discharge canal sampling varied from weekly to monthly, based on monitoring well activity.

Domestic water sampling varied from daily to weekly, based on monitoring well activity. There has been no detectable tritium in the intake and discharge canal water and domestic water samples.

2. Installation of Monitoring Wells A total of 3 monitoring wells were installed in May 2011. Monitoring wells MW-PB-29 and 30 were installed directly east of and adjacent to the Unit 2 Turbine Building; MW-PB-31 was installed southeast of and adjacent to the Unit 2 Turbine Building. All wells are overburden wells. MW-PB-29 is 9.5' deep, MW-PB-30 is 15' deep and MW-PB-31 is 8' deep.

These wells were installed to determine if a condition existed east of the Unit 2 Turbine that was similar to the condition east of the Unit 3 Turbine Building. Additionally, MW-PB-31 is considered to be an early detection well for the Radwaste Discharge line, the Unit 2 Condensate Storage Tank and the Refuel Water Storage Tank. MW-PB-31 is located west of these components, down gradient from the groundwater flow path identified in hydrologic studies.

3. Actions to Recover/Reverse Plumes None.

J.

Deviations The data tables show that duplicate samples were obtained at several wells during 2011. These duplicate samples were obtained and analyzed for quality control purposes.

There are no additional deviations to report.
