This report on the Radiological Environmental Monitoring Program (REMP) conducted for the Peach Bottom Atomic Power Station (PBAPS) by Exelon Nuclear covers the period 1 January 2013 through 31 December 2013. During that time period 1,222 analyses were performed on 952 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, iodine-1 31 (1-131), tritium and gamma emitting nuclides. No fission or activation products were found. Gross beta activity detected was consistent with those observed in previous years. Tritium was not detected in drinking water.

Precipitation samples were analyzed under the Radiological Groundwater Protection Program (RGPP) in 2013.

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 (Cs-1 37) activity was found at one 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 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 I-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity for 1-131.

Examination of the terrestrial environment was accomplished by analyzing milk and food product samples. Milk samples were analyzed for low level concentrations of 1-131 and gamma emitting nuclides. Food product samples were analyzed for concentrations of gamma emitting nuclides. No PBAPS activation or fission products were detected.

Ambient gamma radiation levels were measured quarterly throughout the year.

Most measurements were below 10 mR/standard month and the results were consistent with those measured in previous years.

The results of the Optically-Stimulated Luminescent Dosimetry (OSLD) 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.

Introduction 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 115 MWth High Temperature, Gas-cooled Reactor (HTGR) 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 rated full-power output of approximately 3,514 MWth. 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.

The REMP for PBAPS was initiated in 1966. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Landauer and Environmental Inc.-Midwest Labs (EIML) on samples collected during the period 01 January 2013 through 31 December 2013.

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 2013. Sample locations and descriptions can be found in Table B-1 and Figures B-1 through B-3, Appendix B. The collection procedures used by 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 (133B, 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. Fish samples comprising the flesh from two groups: Bottom Feeder (channel catfish, flathead catfish, carp, redhorse, and quillback) and Predator (smallmouth bass, largemouth bass, green sunfish, and walleye) 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 (1 B, 1 C, 1 Z, 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 three locations (1 Q, 2B and 55; 55 is the control) in May through September. All samples were collected in new unused plastic bags and shipped promptly to the laboratory.

Ambient Gamma Radiation Beginning in 2012, Exelon changed the type of dosimetry used for the REMP. Optically Stimulated Luminescent Dosimetry (OSLD) were deployed and Thermo-luminescent Dosimetry (TLD) were discontinued.

This change may result in a step change in readings, up or down, depending on site characteristics. The relative comparison to control locations remains valid. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation).

The OSLD locations were placed on and around the PBAPS site as follows:

A site boundary ring, consisting of 20 locations (1A, 1 B, 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 OSLD 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), and;

4.

Near the dwelling closest to the vents in the prevailing down wind direction.

Two dosimeters - each comprised of elements enclosed in plastic -

were placed at each location in a Formica "birdhouse" or polyethylene jar located approximately six feet above ground level. The dosimetry 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 2013. 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 and drinking 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.

1.

Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "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 Reporting 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. A 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 water, 11 nuclides, manganese-54 (Mn-54), cobalt-58 (Co-58), iron-59 (Fe-59), cobalt-60 (Co-60), zinc-65 (Zn-65), zirconium-95 (Zr-95), niobium-95 (Nb-95), cesium-1 34 (Cs-1 34), Cs-1 37, barium-1 40 (Ba-140) and lanthanum-140 (La-140) were reported.

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

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

For air particulate, six nuclides, beryllium-7 (Be-7),

Mn-54, Co-58, Co-60, Cs-1 34 and Cs-1 37 were reported.

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

For food products, eight nuclides, Be-7, K-40, Mn-54, Co-58, Co-60, 1-131, Cs-I134 and Cs-i137 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 2013, the PBAPS REMP had a sample collection recovery rate of better than 99%. The exceptions to this program are listed below:

1. On 14 March 2013, the environmental sampling contractor informed the Licensee that the 1Z sample pump was found to have failed. The pump was immediately replaced. An identical air sampler (1A) is located within 6 feet of the 1Z as a quality control independent replicate sample (which is provided to a different laboratory for analysis). A review of the 1A gross beta and iodine data shows no activity, which is consistent with sampling results before and after the 1Z pump failure. The 1Z samples for gross beta and iodine before and after the pump failure are also consistent with historical. No activity was observed in any sample above background.

2.

In May 2013, sufficient mass of broad-leaf vegetation was not obtained due to low crop yield. Vegetation/ Food Products are not required if milk sampling is available and these milk samples were obtained satisfactorily. Two of three samples were obtained from the Station 1Q Indicator Location and zero of three samples were obtained from the Station 2B Indicator Location. All three samples from the Station 55 Control Location were satisfactorily collected.

Subsequent vegetation samples for the year were of satisfactory mass for analysis.

No nuclear power-production radioactivity was above the detection level in any of the samples collected.

3.

The environmental contractor performing sampling of vegetation in July 2013 reported not enough edible portions of plants were available and, using the approved procedures, non-edible portions were collected (e.g. corn and tobacco leaves) at 2 of the three gardens. Although vegetation food-products are desirable for analysis of the dose impact to the public, if not enough edible portions are available, non-edible portions of the same plants are acceptable rather than selecting non-edible plant materials.

No nuclear power-production radioactivity was above the detection level in any of the samples collected.

4.

At the beginning of August, the environmental sampling contractor, NAI, found the enclosure bottle for the dosimeter at location ID Station 26 damaged, possibly by farm activity which suggested that the OSLDs had been dropped to the ground. However, it appears that at some time before the regular change-out, someone replaced the dosimeter in the damaged holder. While the conditions for measurement were not consistent with other quarters, the data indicated that Station 26 direct radiation is consistent with the trends of other quarters. This is most likely due to the dosimeter remaining in the same location relative to Peach Bottom as well as the Independent Spent-Fuel Storage Facility Installation (ISFSI) which is the historical location of the highest-indicating dosimeter (Station ID 1R)

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 There were no program changes in 2013.

IV.

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).

Tritium activity was less than the MDC.

Iodine 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.

Drinking 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 all 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 26 of 36 samples. The values ranged from 1.6 to 5.6 pCi/l. 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-11.2, Appendix C). Tritium activity was less than the MDC.

Iodine Monthly samples from three locations were analyzed for 1-131 (Table C-11.3, Appendix C). All results were less than the MDC.

Gamma Spectrometry Samples from the three 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 2013.

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 2,793 to 4,790 pCi/kg wet and was consistent with levels detected in previous years. No Peach Bottom fission or activation products were found in 2013. A gradual increase in the Cs-1 37 MDC has been observed over the last few years. This change in the baseline is likely the result of historical heat exchanger leaks or nuclear weapons testing legacy material. Historical levels of Cs-137 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 Spectrometry 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 11,170 to 27,460 pCi/kg dry.

The fission product Cs-1 37 was detected in one of six samples at a concentration of 241 pCi/kg. The activity of Cs-1 37 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.

B.

Atmospheric Environment 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 45 E-3 pCi/m 3, with a mean of 18 E-3 pCi/m 3. The results from the Intermediate Distance location (Group II) ranged from 8 to 36 E-3 pCi/m 3 with a mean of 18 E-3 pCi/m 3. The results from the Distant location (Group IlI) ranged from 6 to 30 E-3 pCi/m 3 with a mean of 16 E-3 pCi/m 3. A comparison of the weekly mean values for 2013 indicate no notable differences among the three groups (Figure C-4, Appendix C). In addition, a comparison of the 2013 air particulate data with previous years data indicate no effects from the operation of PBAPS (Figure C-5, 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 19 of 20 samples. The values ranged from 49 to 89 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 for 1-131.

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 for 1-131. All results were less than MDC for 1-131 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 1,059 to 1,575 pCi/l. All other nuclides were less than the MDC and all required LLDs were met. Comparison of the 2013 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 three locations (1 Q, 2B 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:

13-

Gamma Spectrometry Each food product sample from locations 1Q, 2B and 55 was analyzed for concentrations of gamma emitting nuclides (Table C-VIII.1, Appendix C).

Naturally occurring Be-7 activity was found in 27 of 39 samples and ranged from 108 to 4,236 pCi/kg wet.

Potassium-40 activity was found in all samples and ranged from 2,415 to 11,180 pCi/kg wet. All other nuclides were less than the MDC.

C.

Ambient Gamma Radiation Beginning in 2012, Exelon changed the type of dosimetry used for the REMP. OSLDs were deployed however, TLD monitoring is continuing at PBAPS as a side-by-side technology comparison study but official reporting is from OSLD data. This change may result in a step change in readings, up or down, depending on site characteristics. The relative comparison to control locations remains valid. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation). Results of OSLD measurements are listed in Tables C-IX. 1 through C-IX.3 and Figure C-7, Appendix C.

Most OSLD measurements were below 10 mR per standard month, with a range of 5.0 to 13.0 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)

ISFSI was utilized beginning June 2000. During 2013, 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) for the period of 2000 to about 2007. A general decrease has been observed, however, for the period of 2007 to the present. Location 2B, which represents the nearest residence, showed a small effect in dose rate from the ISFSI pad. Data from location 2B is used to demonstrate compliance to both 40CFR190 and 10CFR72.104 limits. The large reduction in multiple direct radiation locations for 2013 is a result of the difference in technology used for radiation measurement (from TLD to OSLD).

E.

Land Use Census A Land Use Survey conducted during the fall of 2013 around the PBAPS was performed by NAI 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. There were no changes in the nearest residence, garden or milk farms from the previous year.

Errata Data Teledyne Brown Engineering (TBE) provides data results [activity, uncertainty and minimum detectable concentration {MDC}]. We are required to calculate the MDC using a multiplier of 4.66.

4.66 MDC =At 2.22 (v)(y) (a)(E)

Where:

At = counting time for sample (minutes)

P = background rate of instrument blank (cpm) 2.22 = dpm/pCi or: 2.22 x 106 dpm/gtCi v = volume or mass of sample analyzed y = chemical yield

= efficiency of the counter A = radioactive decay constant for the particular radionuclide a = exp (-AAt)

The formulas for calculating the activity, uncertainty and MDC are contained in the software of the counting equipment. For the gamma system, when the new detector number 08 was added to the system in January 2012, the default value of 3.29 was used to calculated the MDCs on detector 08. The activity and uncertainty were not affected. The multiplier has been changed from 3.29 to the required 4.66.

When the MDCs are recalculated using 4.66, the MDC values will increase by 41.6%. The greatest impact will be on the short-lived nuclides which have an LLD requirement, e.g. 1-131, Ba-140 and La-140. Which means there could be some missed LLDs which will be identified in the Errata Data Appendix table of the 2013 annual report. This is not a reportable issue for the NRC. There is also the possibility that naturally produced nuclides that were detected would become a non-detect, e.g thorium-228 (Th-228), thorium-230 (Th-230), etc.

The errata data are given in Appendix F of this report G.

Secondary Laboratory Analysis The Appendix D section of this report presents the results of data analysis performed by the QC laboratory, EIML. Duplicate samples were obtained from several locations and media and split between the primary laboratory, TBE and the EIML. Comparisons of the results for all media were within expected ranges.

H.

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 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 TBE laboratory, 178 out of 185 analyses performed met the specified acceptance criteria. Seven analyses (Sr-89 and Sr-90 in milk, Co-57, Zn-65 and Sr-90 in soil, Cs-1 34 in air particulate and Sr-90 in vegetation [two low warning in a row]) did not meet the specified acceptance criteria or internal QA requirements for the following reason:

1.

TBE's Analytics September 2013 Sr-89 in milk result of 63.9 pCi/L was lower than the known value of 96.0 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample.

Client samples for the associated time period were evaluated and no client samples were affected by this failure. Non-Conformance Report (NCR) 13-15

2.

TBE's Analytics September 2013 Sr-90 in milk result of 8.88 pCi/L was lower than the known value of 13.2 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample.

Client samples for the associated time period were evaluated and no client samples were affected by this failure. NCR 13-15

3. & 4.TBE's MAPEP September 2013 Co-57 and Zn-65 in soil were evaluated as failing the false positive test.

While MAPEP evaluated the results as failures, the gamma software listed the results as non identified nuclides. The two nuclides would never have been reported as detected nuclides to a client. MAPEP does not allow laboratories to put in qualifiers for the submitted data nor "less than" results. MAPEP evaluates results based on the relationship between the activity and the uncertainty. MAPEP spiked the soil sample with an extremely large concentration of europium-152 (Eu-152), which was identified by the gamma software as an interfering nuclide, resulting in forced activity results that were evaluated by MAPEP as detected Co-57 and Zn-65. No client samples were affected by these failures.

NCR 13-14

5.

TBE's MAPEP September 2013 Sr-90 in soil result of 664 Bq/kg was higher than the known value of 460 Bq/kg, exceeding the upper control limit of 598 Bq/kg. An incorrect Sr-90 result was entered into the MAPEP database. The correct Sr-90 activity of 322 Bq/kg would have been evaluated as acceptable with warning.

No client samples were affected by this failure. NCR 13-14

6.

TBE's MAPEP September 2013 Cs-1 34 in air particulate activity of

-0.570 Bq/sample was evaluated as a failed false positive test, based on MAPEP's evaluation of the result as a significant negative value at 3 standard deviations. A negative number would never have been reported as a detected nuclide to a client, therefore no client samples were affected by this failure. NCR 13-14

7.

TBE's MAPEP September 2013 Sr-90 in vegetation result was investigated due to two low warnings in a row. It appears the September sample was double spiked with carrier, resulting in a low activity. With a recovery of around 50% less, the Sr-90 result would have fallen within the acceptance range. No client samples were affected by this issue. NCR 13-14 For the EIML laboratory, 89 of 92 analyses met the specified acceptance criteria. Three analyses (AP - Gross Alpha, Soil - Sr-90 and Co-57) did not meet the specified acceptance criteria for the following reasons:

1.

EIML's MAPEP February 2013 air particulate gross alpha result of 0.14 Bq/total sample was lower than the known value of 1.20 Bq/

total sample, exceeding the lower control limit of 0.36 Bq/total sample. The filter was recounted overnight. No significant activity could be detected.

2.

EIML's MAPEP February 2013 soil Co-57 result of 408.40 Bq/kg was lower than the known value of 628.0 Bq/kg, exceeding the lower control limit of 440.0 Bq/kg. The sample was reanalyzed using additional fuming nitric separations. The reanalysis result of 574.4 fell within the control limits.

3.

EIML's MAPEP August 2013 soil Co-57 result of 699.60 Bq/kg was higher than the known value of 0.00 Bq/kg, exceeding the upper control limit of 5.00 Bq/kg. Interference from Eu-1 52 resulted in misidentification of Co-57.

The Interlaboratory Comparison Program (ICP) provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

(2) Soil, Co-57 & Zn-65 identified by gamma software as not detected, MAPEP evaluated as failing the false positive test. A large concentration of Eu-152 was spiked into the sample, causing interference in the analysis. Gamma software recognized the interference and identified them as not detected. MAPEP does not allow clients to enter non-detect designation. NCR 13-04 Soil, Sr incorrect results were submitted to MAPEP. Actual result was 332 bq/kg, which is within the acceptance range. NCR 13-04 AP, Cs-134 - MAPEP evaluated the -0. 570 as a failed false positive test. No client samples were affected by these failures. NCR 13-04 Vegetation, Sr it appears that the carier was double spiked into the sample, resulting in the low activity for this sample. NCR 13-04 (a) Teledyne Brown Engineering reported result.

APPENDIX F ERRATA DATA

Errata Data Incorrect Setting on Gamma Spectroscopy Detector at TBE Due to an incorrect setting on gamma detector 08, 3.29 rather than 4.66 was used in the MDC calculation. Nonconformance 13-07 was initiated and corrective actions have been implemented to address this issue. All samples counted on detector 08 were reprocessed using the correct calculation. As a result, all MDCs for these samples have increased by 41.6%. The previously reported activities and uncertainties were not affected. In some cases, the increased MDC resulted in missed LLDs. All samples with MDCs affected by this issue are listed below. The samples with missed LLDs are shown in the table for 2011, 2012, and 2013. All other required LLDs were met.

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 2013 through 31 December 2013. This evaluation involved numerous station personnel and contractor support personnel. At PBAPS, 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 REMP. This is the seventh in a series of annual reports on the status of the RGPP conducted at PBAPS. This report covers groundwater, surface water and seep water samples collected from the environment on station property in 2013. During that time period, 465 analyses were performed on more than 243 samples from 41 locations. These 41 locations include 27 groundwater monitoring wells, 3 surface water sample points, 3 groundwater seeps and 2 yard drain sumps (groundwater) and 6 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 PBAPS 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 PBAPS had no adverse radiological impact on the environment and there are no known active releases into the groundwater at PBAPS.

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-89 (Sr-89) and strontium-90 (Sr-90) were not detected in any of the samples. (Table B-1.1, Appendix B).

Tritium was not detected in any groundwater locations at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission [NRC] Reporting Limit) of 20,000 pCi/L. Low levels of tritium were detected at concentrations greater than the minimum detectable concentration (MDC) in 10 of 27 groundwater monitoring wells. The tritium concentrations ranged from 176 +/- 115 pCi/L to 10,700 + 1,110 1

pCi/L (Table B-1.1, Appendix B). Tritium was not detected at concentrations greater than the MDC in any surface water, seep water or precipitation water sample locations. Based on the sample data tritium is not migrating off the station property at detectable concentrations. No tritium was detected in any surface water samples (Table B-11.1, Appendix B). No tritium was detected in any precipitation water samples (Table B-11.1, Appendix B).

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during 2013. Gross Alpha (dissolved) was detected in 10 of 25 groundwater locations analyzed. The concentrations ranged from 0.7 to 12.1 pCi/L. Gross Alpha (suspended) was detected in 4 of 25 groundwater locations analyzed. The concentrations ranged from 1.2 to 4.2 pCi/L. Gross Beta (dissolved) was detected in all 25 groundwater locations analyzed. The concentrations ranged from 1.2 to 20.3 pCi/L. Gross Beta (suspended) was detected in 8 of 25 groundwater locations analyzed. The concentrations ranged from 2.6 to 10.8 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 (Table B-1.3, Appendix B).

The analyses for groundwater included iron-55 (Fe-55), nickel-63 (Ni-63),

americium-241 (Am-241), curium-242 (Cm-242), Cm-243/244, plutonium-238 (Pu-238), Pu-239/240, uranium-234 (U-234), U-235 and U-238. U-234 was detected in four of five groundwater monitoring locations analyzed. The concentrations ranged from 0.53 to 7.30 pCi/L. U-238 was detected in three of five groundwater monitoring locations analyzed. The concentrations ranged from 0.61 to 3.32 pCi/L. No plant produced radionuclides were detected.

Introduction 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 115 MVfth high temperature, gas-cooled reactor (HTGR) 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 rated full-power output of approximately 3514 MWth. 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 2013.

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, soil or surface 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

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.

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).

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 the Nuclear Energy Institute (NEI).

Program Description

1.

Sample Collection Sample locations can be found in Table A-1 and Figures A-1 and A-2, Appendix A.

4

Groundwater, Surface Water and Precipitation Water Samples of water are collected, managed, transported and analyzed in accordance with approved procedures. Groundwater, surface water, and precipitation 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.

D.

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

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 emits a low energy beta particle 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 Environmental Inc. Midwest Laboratories (EIML) to analyze the environmental samples for radioactivity for the PBAPS RGPP in 2013.

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

1.

Concentrations of 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 in groundwater and surface water.

2.

Concentrations of Sr-89, Sr-90 in groundwater

3.

Concentrations of H-3 in groundwater, surface water and precipitation 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 PBAPS becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, PBAPS 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.

6

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 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 PBAPS, Environs Radiation Monitoring Program, Preoperational Summary Report Units 2 and 3, September 1970- August 1973, January 1974 and PBAPS, 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.

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 worldwide from 1960 to 2006.

RadNet provides tritium precipitation concentration data for samples collected at stations throughout the U.S. from 1960 up to and including 2006. Based on GNIP data for sample 8

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 27 locations were analyzed for tritium activity (Table B-1.1, Appendix B). Tritium values ranged from the detection limit to 10,700 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 MDC (Table B-I. 1, Appendix B).

Strontium Sr-89 and Sr-90 were not detected in any of the samples (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 2013. Gross Alpha (dissolved) was detected in 10 of 25 groundwater locations analyzed. The concentrations ranged from 0.7 to 12.1 pCi/L. Gross Alpha (suspended) was detected in 4 of 25 groundwater locations analyzed. The concentrations ranged from 1.2 to 4.2 pCi/L. Gross Beta (dissolved) was detected in all 25 groundwater locations analyzed. The concentrations ranged from 1.2 to 20.3 pCi/L. Gross Beta (suspended) was detected in 8 of 25 groundwater locations analyzed. The concentrations ranged from 2.6 to 10.8 pCi/L. The activity detected is naturally occurring and the levels are considered to be background (Table B-I. 1, Appendix B).

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-10

241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235, and U-238. U-234 was detected in four of five groundwater monitoring locations analyzed. The concentrations ranged from 0.53 to 7.30 pCi/L. U-238 was detected in three of five groundwater monitoring locations analyzed. The concentrations ranged from 0.61 to 3.32 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 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).

C.

Precipitation Water Results Precipitation Water Samples were collected at six locations (1A, 1B, 1S, 1SSE, 1Z, and 4M). The following analysis was performed:

Tritium Samples from six locations were analyzed for tritium activity. Tritium activity was not detected in any samples (Table B-111.1, Appendix B).

Drinking Water Well Survey A drinking water well survey was conducted during the summer 2006 by CRA (CRA 2006) around the PBAPS. The water well inventory was updated in 2012. The updated water well database search indicated a new water well off Station property within a one mile radius of the Station. The well is described as a "test" well and its use is listed as "unused". In summary, there were no significant changes in off Station groundwater use from 2006-2012.

Leaks, Spills and Releases There were no leaks, spills or releases of water containing licensed material to environment in 2013.

G.

Trends A tritium plume has been identified northeast of the Unit 3 Turbine Building. 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.

Wells MW-PB-4, 24, 25, 26 and 27 were each sampled and analyzed 9 times during 2013. On 8 occasions, MW-PB-25 samples had the highest tritium activity. MW-PB-27 had the highest activity 1 time, on January 2, 2013.

MW-PB-27 activity from the sample on January 2, 2013, was the result of the tritium plume migrating southward due to groundwater dewatering activities associated with a buried pipe inspection. In the next sampling, performed on January 7, 2013, MW-PB-25, had the highest tritium activity.

In each subsequent 2013, MW-PB-25 had the highest tritium activity. This was an expected condition as the dewatering activities terminated in December 2012, returning the tritium plume to its pre-dewatering location.

All wells exhibited decreasing trends during 2013. The increased sampling frequency to monitor changes due to dewatering, was continued through January 2013. The sampling frequency returned to quarterly after well activity trended toward pre-dewatering results.

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 are the wells installed directly east of and adjacent to the Unit 3 Turbine Building, 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 Building 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 Building 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 Building 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 of and adjacent to the Unit 2 Turbine Building. These wells were installed to determine if a condition existed east of the Unit 2 Turbine Building that is similar to the condition east of the Unit 3 Turbine Building.

Wells MW-PB-29, 30 and 31 were sampled a total of 18 times in 2013.

Tritium activity in the wells ranged from less than the MDC 449 +/- 144 pCi/L. Samples from these wells were also analyzed for gamma emitting isotopes and hard to detect radionuclides. All results were less than the MDC for each isotope.

The Unit 2 Turbine Building Moisture Separator area 116' elevation floor was sealed and recoated in October 2012. Groundwater intrusion into a ventilation pit on the east side of the area was identified. The groundwater was removed and degraded seams in the ventilation pit were successfully repaired.

MW-PB-4, 24, 25, 26 and 27 Wells MW-PB-4, 24, 25, 26 and 27 are considered the wells of primary interest. These wells were sampled on a frequency that ranged from weekly to quarterly. 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 2013. The tritium activity is in pCi/L.

The most likely pathway for tritium to enter the groundwater was 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 generally-decreasing trend since these repairs were completed Actions Taken

1. Compensatory Actions Wells, MW-PB-4, 20, 21, 22, 24, 25, 26, 27, 29 and 30 were sampled and analyzed for tritium on a weekly to quarterly frequency. These wells were sampled on a frequency greater than that required by Station procedures, when determined to be necessary to evaluate potential changes in tritium activity. The increased sample frequency was performed to monitor the effectiveness of repairs completed in the Unit 3 Turbine Building and to 14

monitor potential changes in the tritium plume due to dewatering of the excavation used for the buried pipe inspection.

2. Installation of Monitoring Wells No groundwater monitoring wells were installed in 2013.

3. Actions to Recover/Reverse Plumes There were no actions to recover the plume.

J.

Deviations The data tables show that duplicate samples were obtained at several wells during 2013. These duplicate samples were obtained and analyzed for quality control purposes.

There are no additional deviations to report.
