I. Summary During normal operations of a nuclear power generating station there are permitted releases of small amounts of radioactive material to the environment. To monitor and determine the effects of these releases a Radiological Environmental Monitoring Program (REMP) has been established around the Susquehanna Steam Electric Station (SSES). The results of the REMP are published annually, providing a summary and interpretation of the data collected.

Ecology Ill was responsible for the collection of environmental samples during 2015. Teledyne Brown Engineering (TBE) was responsible for the analysis of environmental samples during 2015. The results are discussed in this report. Landauer provided the dosimetry services for SSES du.ring 2015.

This Annual Radiological Environmental Operating Report (AREOR) conducted for SSES covers the period January 1, 2015 through December 31, 2015. During that time period, 1534 analyses were performed on 1307 samples.

Of the two man-made radionuclides (tritium [H-3] and cesium-137 [Cs-137])

detected in the environment by the Susquehanna Steam Electric Station (SSES) Radiological Environmental Monitoring Program (REMP), tritium is the only radionuclide attributable to SSES operation. The whole body and organ dose to members of the public attributable to tritium identified in REMP cooling tower blowdown samples was 8.50E-04 mRemc Tritium was included in the* dose calculation because it was identified in the REMP samples of permitted water being discharged to the Susquehanna River. The 2015 average concentration of tritium in the cooling tower blowdown water and the 2015 average cooling tower blowdown flow were used to determine the amount of tritium released. The presumed exposure pathways to the public from this radionuclide were drinking water taken from the Susquehanna River at Danville, PA and eating fish caught near the SSES discharge to the river.

Dose from ground plane deposition (shoreline exposure) is not applicable because tritium does not emit gamma radiation and the beta radiation emitted by tritium is not sufficiently penetrating to reach an individual on the shore.

Based on the above outlined methodology, the total tritium activity released from the SSES to the Susquehanna River in 2015 was 56.7 curies.

The 2015 average dilution factor for the Susquehanna River was 433, based on the annual average river flow of 5.59E+06 gpm and the annual average cooling tower blowdown flow of 1.29E+04 gpm.

The REMP Sample Equipment Operability and year to year trend comparison is located in Appendix E, Table E-1 The REMP was conducted in accordance with the SSES Technical Requirements Manual (TRM) and the respective station Offsite Dose Calculation Man_ual (ODCM) which are based on the design obj~ctives in 10CFR Part 50, Appendix I, Sections IV.B.2, IV.B.3 and IV.C. The Lower .

Limit of Detection (LLD) values required by the TRM and SSES ODCM were achieved for the 2015 reporting period. The REMP objectives were also met during this period. The concentration of radioactive material in the environment that could be attributable to SSES operations was only a small fraction of the concentration of naturally occurring and man-made radioactivity. Since these results were comparable to the results obtained during the preoperational phase of the program and combined with historical results collected since commercial operation, it can be concluded that the levels and fluctuations were as expected and that the operation of the SSES had no significant radiological impact on the environment. Additionally, the REMP sample results for 2015 verify the adequacy of the SSES radioactive effluent control systems.

Samples of air particulates, air iodine, milk, groundwater, drinking water, vegetation, soil, surface water, fish and sediment were collected and analyzed. External radiation dose measurements were also made in the vicinity of SSES using passive dosimeters.

Air particulate samples were analyzed for concentrations of gross beta weekly and gamma emitting nuclides quarterly. Gross beta and cosmogenically produced beryllium-7 (Be-7) were detected at levels consistent with those detected .in previous years. No fission or activation products were detected.

High sensitivity iodine-131 (1-131) analyses were performed on weekly air samples. All results were less than the minimum detectable concentration.

Environmental gamma radiation measurements Were performed quarterly using Optically Stimulated Luminescent dosimeters (OSLO). The levels of radiation qetected were consistent with those observed in previous years.

Cow milk samples were analyzed for concentrations of 1-131 and gamma emitting nuclides. All l-131 results were below the minimum detectable concentration. Naturally occurring potassium-40 (K-40) was detected at

~evels consistent with those detected in previous years. No fission or activation products were detected.

Groundwater samples were analyzed for concentrations of tritium and gamma emitting nuclides. Tritium activities detected were consistent with those detected in previous years. No fission or activation products were detected.

Drinking water samples were analyzed for concentrations of tritium, gross beta and gamma emitting nuclides. Tritium and gross beta activities detected were consistent with those detected in previous years. No fission or activation products were detected.

Food product (fruits, vegetables and broad leaf vegetation) samples were analyzed for concentrations of gamma emitting nuclides. Naturally occurring potassium-40 was detected at levels consistent with those detected in previous years. No fission or activation products were detected.

Soil samples were analyzed for concentrations of gamma emitting miclides.

Naturally occurring isotopes (i.e. K-40, thorium-228 [Th-228], radium-226

[Ra-226] and actinium-228 [Ac-228]), were detected at levels consistent with previous years. Cs-137 was not detected in any of the soil samples in 2015.

Historical and preoperational data consistently indicates that Cs-137 previously detected in the soil is due to residual fallout from atmospheric nuclear weapons testing in the 1970s and early 1980s .and the 'Chernobyl and Fukushima events and is not attributable to station operations.

Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Tritium activities detected were consistent with those detected in previous years. No fission or activation products were detected.

Fish and shoreline sediment samples were analyzed for concentrations of gamma emittin*g nuclides. No fission or activation products were detected in fish or sediment samples.

II. The Radiological Environmental Monitoring Program The Susquehanna Steam Electric Station (SSES) is a nuclear electrical generating facility with two boiling-water reactors and generators located just west of the Susquehanna River, approximately 5 miles northeast of Berwick, in Luzerne County, Pennsylvania. The station was constructed in the 1970's, with Unit 1 beginning commercial operation on June 8, 1983, and Unit 2 beginning commercial operation on February 12, 1985. Units 1 and 2 each generate a net 1,350 megawatts (MWe), for a total station output of 2,700 MWe.

In total Susquehanna Nuclear, LLC presently owns 2,347 acres of land on both sides of the Susquehanna River. Generally, this land is characterized by open deciduous woodlands interspersed with grasslands and orchards.

On the west side of the river, 1,605 (1,670 minus 65 acre Gould Island) acres of land is jointly owned between Susquehanna Nuclear, LLC (90%) and Allegheny Electric Cooperative (10%). The land use on the west side of the river includes generation & associated maintenance facilities, laydown areas, parking lots, roads, a nature preserve (the Susquehanna Riverla'nds),

and agricultural leases to local farmers.

To the north of the Station along the river, Susquehanna Nuclear, LLC owns 100% of the 65-acre Gould Island. On the east side of the river, and across the river from the Station, Susquehanna Nuclear, LLC is the 100% owner of 677 acres that are maintained as undeveloped land, natural recreational areas, wildlife areas, and leases to local farmers.

More specific information on the demography, hydrolo_gy, meteorology, and land use characteristics of the area in the vicinity of the SSES can be found in the Environmental Report [Reference 1], the Final Safety Analysis Report

[Reference 2] and the Final Environmental Statement [Reference 3] for the SSES.

Radioanalytical data from samples collected under the REMP were compared with results from the preoperational phase and historical results during operations. Differences between these periods were examined statistically to determine the effects of station operations. This report presents the results from January 1 through December 31, 2015, for the SSES Radiological Environmental Monitoring Program (REMP).

A. Objectives of the Operational REMP The objectives of the Operational REMP are to:

1.

Do6ument compliance with SSES REMP Technical Requirements and radiological ~nvironmental surveillances.

2.. Verify proper implementation of SSES radiological effluent controls.

3. Identify, measure and evaluate trends of radionuclide concentrations in environmental pathways near SSES.

4. Assess impact of SSES Effluents on the Environment and the public.

5. To verify that SSES operations have no detrimental effects on the health and safety of the public or on the environment.

B. Implementation of the Objectives

1. In order to meet the objectives, an operational REMP was developed. Samples of various media were selected for monitoring due to the radiological dose impact to humans and other organisms. The selection of samples was based on:

(a) Established critical pathways for the transfer of radionuclides through the environment to man, and (b) Experience gained during the preoperational phase.

Sampling locations were determined based on site meteorology, Susquehanna River hydrology, local demography, and land uses.

2. Sampling locations were divided into two classes, indicator and control. Indicator locations are sited where it is expected that radiation and radioactive material that might originate from the station would be detectable. Control locations are selected in areas where they would be unaffected by station operations (i.e. Susquehanna River upstream from the station, >10 miles from the station in least prevalent wind directions). Fluctuations in the levels of radionuclides and direct radiation at indicator locations are evaluated with respect to analogous fluctuations at control locations. Indicator and control location data are also evaluated relative to preoperational data.

3. Appendix A, Program Summary, describes and summarizes the analytical results in accordance with the SSES Technical Specifications.

4. Appendix B, Sample Designation and Locations, describes the coding system which identifies sample type and location. Table B-1 lists the location codes, locations, latitude, longitude, and the types of samples collected at each location. Table B-2 contains sample medium, analysis and sampling details.

5. The sampling locations are indicated on the following maps:

Program Description A. Data Interpretation Results of analyses are grouped according to sample type and presented in Appendix C, Data Tables. All results above the Lower Limit of Detection (LLD) are at a confidence level of+/- 2 sigma. This represents the range of values into which 95% of repeated analyses of the same sample should fall. As defined in U.S. Nuclear Regulatory Commission Regulatory Guide 4.8, LLD is the smallest concentration of radioactive material in a sample that will yield a net count (above system background) that will be detected with 95% probability, with only 5% probability of falsely concluding that a blank observation represents a "real signal". LLD is normally calculated as 4.66 times the standard deviation of the background counting rate, or of the blank sample count, as appropriate, divided by counting efficiency, sample size, 2.22 (dpm per picocurie), the radiochemical yield when applicable, the radioactive decay constant and the elapsed time between sample collection and time of counting. The LLD is an "a priori" number which represents the capability of the measurement system.

The Minimum Detectable Concentration (MDC) is defined as the smallest concentration of radioactive material that can be detected at a given confidence level. The MDC differs from the LLD in that the MDC takes into consideration the interference caused by the presence of other nuclides while the LLD does not. The MDC is an "a posteriori" number which is an indicator of the performance of the measurement system. The MDC is set to be below the LLD.

The grouped data were averaged and standard deviations calculated.

Thus, the +/- 2 sigma deviations of the averaged data represent sample and not analytical variability. For reporting and calculation of averages, any result occurring at or below the LLD is considered to be at that level.

C. Program Changes Two AP filter and Air Iodine locations, 9B1 and 1OS3 were added to the program in 2015.

No samples were collected at location 5S9 in 2015. An alternate location, 6S6 was used in the place of 5S9.

D. Quality Assurance Program Teledyne Brown Engineering The quality of the results obtained by TBE is ensured by the.

implementation of the Quality Assurance Program as described in the Teledyne Brown Engineering Quality Assurance Manual and the Teledyne Brown Engineering Procedure Manual.

E. Summary of Results - Inter-laboratory Comparison Program The TBE laboratory performed 139 analyses of Performance Evaluation (PE) containing spiked samples of air particulate, air iodine, milk, soil, vegetation and water matrices, as part of the Teledyne Quality Control Spike Program. (Appendix D, Tables D-1 through D-3),

The PE samples, Susquehanna Nuclear supplied by Analytics Inc.;

Environmental Resource Associates (ERA) and Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following acceptance criteria:

1. Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of reported result and Analytics' known ~alue. 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 ERA's evaluation report provides an acceptance range for control and warning limits with associated flag v_alues. ERA's acceptance limits are established per the United States Environmental Protection Agency (USEPA), National Environmental Laboratory Conference (NELAC) performance

. testing (PT) program requirements or ERA's standard operating procedure (SOP) for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined* by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.

The MAPEP defines three levels of performance: Acceptable (flag ="A"), Acceptable with Warning (flag ="W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value. Performance is acceptable with warning when a mean result falls in the range from +/- 20% to +/- 30% of the reference value (i.e., 20% <bias< 30%). If the bias is greater than 30%, the results are deemed not acceptable.

Teledyne Brown Engineering For the TBE laboratory, 131 out of 139 analyses performed met the specified acceptance criteria. Eight analyses (AP - Cr-51, U-234/233, Gr-A, Sr-90; Soil Sr-90; Water Ni-63, U natural; Vegetation Sr-90 samples) did not meet the specified acceptance criteria forthe following reasons and were addressed through the TBE Corrective Action Program:

Please note: the Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which in no way resemble typical environmental samples.

1. . Teledyne Brown Engineering's Analytics' June 2015 air particulate Cr-51 result of 323 +/- 45.5 pCi was higher than the known value of 233 pCi with a ratio of 1.39. The upper ratio of

.1.30 (acceptable with warning) was exceeded. The air particulate sample is counted at a distance above the surface of the detector to avoid detector summing which could alter the results. Chromium-51 has the shortest half-life (27.7 days) and the lowest gamma energy (320.08 keV) of this mixed nuclide sample. Additionally, Cr-51 has only one gamma energy and also has a low intensity (9.38 gamma photons produced per 100 disintegrations). This geometry produces a larger error for the Cr-51 and other gamma emitters as any distance from the detector decreases the counting rate and the probability of accurately detecting the nuclide energy. Taking into consideration the uncertainty, the activity of Gr-51 overlaps with the known value at a ratio of 1.19, which would statistically be considered acceptable. NCR 15-18

2. . Teledyne Brown Engineering's MAPEP March 2015 soil Sr-90 result of 286 Total Bq/kg was lower than the known value of 653 Bq/kg, exceeding the lower acceptance range of 487 Bq/kg. The failure was due to incomplete digestion of the sample. Incomplete digestion of samples causes some of the sample to be left behind and is not present in the digested sample utilized for analysis. The procedure has been updated to include a more robust digestion using stirring during the heating. The MAPEP September 2014 soil Sr-90 series prior to this *study was evaluated as acceptable with a result of 694 and an acceptance range of 601 - 1115 Bq/kg. The MAPEP September 20*15 ~eries soil Sr-90 after this study was evaluated as acceptable with a result of 429 and an acceptance range of 298 - 553 Bq/kg. We feel the issue is specific to the March 2015 MAPEP sample. NCR 15-13

3. Teledyne Brown Engineering's MAPEP March 2015 air particulate U-234/233 result of 0.0211 +/- 0.0120 Sq/sample was higher than the known value of 0.0155 Sq/sample, exceeding the !Jpper acceptance range of 0.0202 Sq/sample. Although evaluated as a failure, taking into consideration the uncertainty, TBE's result would overlap with the known value, which is statistically considered acceptable. MAPEP spiked the sample with significantly more U-238 activity (a found to known ratio of 0.96) than the U-234/233. Due to the extremely low activity, it was difficult to quantify the U-234/233. NCR 15-13

4. Teledyne Brown Engineering's MAPEP March 2015 air particulate gross alpha result of 0.448 Sq/sample was lower than the known value of 1. 77 Sq/sample, exceeding the lower acceptance range of 0.53 Sq/sample. The instrument efficiency used for gross alpha is determined using a non-attenuated alpha standard. The MAPEP filter has the alphas embedd.ed in the filter, requiring an attenuated efficiency. When samples contain alpha particles that are embedded in the sample media, due to the size of the alpha particle, some of the alpha particles are absorbed by the media and cannot escape to be counted. When the sample media absorbs the alpha particles this is known as self-absorption or attenuation. The calibration must include a similar configuration/media to correct for the attenuation. In order to correct the low bias, TBE will create

'f an attenuated efficiency for MAPEP air particulate filters.

The MAPEP September series air particulate gross alpha result of 0.47 Sq/sample was evaluated as acceptable with a range of 0.24 - 1.53 Sq/sample. Air particulate Gross alpha analyses for power plants are not evaluated as a direct count sample, which the MAPEP sample is. Power plant air particulate filters for gross alpha go through an acid digestion prior to counting.

NCR 15-13

.5. Teledyne Brown Engineering's MAPEP.September water Ni-63 result of 11.8 +/- 10.8 Bq/l was higher than the known value of 8.55 Bq/l, exceeding the upper acceptance range of 11.12 Bq/L. The Ni-63 half-life is approximately 100 years. Nickel-63 is considered to be a "soft" or low energy beta emitter, which means that the beta energy is very low. The maximum beta energy for Ni-63 is approximately 65 keV, much lower than other more common nuclides such as Co-60 (maximum beta energy of 1549 keV). The original sample was run with a 10 ml aliquot which was not sufficient for the low level of Ni-63 in the sample. The rerun aliquot of 30 ml produced an acceptable result of 8.81 Bq/l. NCR 15-21

)

6. Teledyne Brown Engineering's MAPEP September air particulate Sr-90 result of 1.48 Sq/sample was lower than the known value of 2.18 Sq/sample, exceeding the lower acceptance range of 1.53 Sq/sample. In the past; MAPEP has added substances (unusual compounds found in DOE complexes) to various matrices that have resulted in incomplete removal of the isotope of interest for the laboratories analyzing the cross checks. TBE suspects that this may be the cause of this error. Many compounds, if not properly accounted for or removed in the sample matrix, can cause interferences to either indicate lower activity or higher activity. TBE will no longer analyze the air particulate Sr-90 through MAPEP but will participate in the Analytics cross check program to perform both Sr-89 and Sr-90 in the air particulate matrix. NCR 15-21

7. Teledyne Brown Engineering's MAPEP September vegetation Sr-90 result of 0.386 Sq/sample was lower than the known value of 1.30 Sq/sample, exceeding the lower acceptance range of 0.91 Sq/sample. In the past, MAPEP has added substances (unusual compounds found in DOE complexes) to various matrices that have resulted in incomplete removal of the isotope of interest for the laboratories analyzing the cross checks. TBE suspects that this maybe the cause of this error.

Many compounds, if not properly accounted for or removed in the sample matrix, can cause interferences to either indicate lower activity or higher activity. NCR 15-21

8. Teledyne Brown Engineering's ERA November water Uranium natural result of 146.9 pCi/l was higher than the known value of 56.2 pCi/l, exceeding the upper acceptance limit of 62.4 pCi/L. The technician failed to dilute the original sample, but used the entire 12 ml sample. When the results were

. recalculated without the dilution and using the 12 ml aliquot, the result of 57.16 agreed with the assigned value of 56.2.

NCR 15-19 In addition, Susquehanna Nuclear's REMP Laboratory Spike Program provided indep~ndently procured Analytics spiked samples as part of Susquehanna Nuclear's Quality Control Spike Program.

The criteria for the acceptability of the spiked analysis results were established by Susquehanna Nuclear and are based on criteria originally developed by the NRC. The criteria are based on an empirical relationship that combines prior experience and accuracy needs. As the resolution of the measurement process improves, the criteria for determining acceptability become tighter.

Conversely, as the resolution of the process becomes poorer, the criteria for determining acceptability become wider.

The TBE laboratory performed 139 analyses .of Performance Evaluation (PE) containing spiked samples of air particulate, air iodine,-milk, soil and water ~atrices. (Appendix D, Table D-4)

For the TBE laboratory, 134 out of 139 analyses performed met the specified acceptance criteria. Five analyses (two Cr-51 and one Fe-59 in an air particulate, a Cr-51 in soil and Ce-141 in milk) did not meet the specified acceptance criteria or internal QA requirements.

The TBE laboratory initiated Nonconformance Report 16-06 to address the failures.

IV. Results and Discussion T.he analytical results of the 2015 REMP samples are divided into categories based on exposure pathways: atmospheric, direct radiation, terrestrial, and aquatic. The analytical results for the 2015 REMP are summarized in Appendix A, Program Summary. The data for individual samples are presented in Appendix C, Data Tables. The data are compared to the formal preoperational environmental monitoring program data (April 1972 to September 1982) and to historical data during operations. The data collected demonstrates that the SSES REMP was conducted in compliance with the TRM and the SSES ODCM.

A. Atmospheric Atmospheric REMP sampling includes the collection of air particulate, air iodine and direct radiation samples.

1. Air Particulates Air particulate samples were collected weekly at six indicator

(

locations (3S2, 981, 10S3, 12E1, 12S1and13S6) and two control locations (6G1 and 8G1 ). Each of the samples collected for the year were analyzed for gross beta. Quarterly composites of the weekly samples from each location were analyzed for specific gamma emitters.

Gross Beta Gross beta activity *was detected in 312 of 312 of the indicator location samples at concentrations ranging from 3 to 30 E-3 pCi/m 3 with an avera~e concentration of 14 E-3 pCi/m 3, and in 99 of 99 of the control location samples at concentrations ranging from 6 to 28 E"'.'3 pCi/m 3 with an average of 14 E-3 pCi/m 3 . The maximum preoperational level detected was 102 E-3 pCi/m 3 with an average concentration of 62 E-3 pCi/m 3 .

(Table C-1, Appendix C); Historical levels of gross beta are shown in Figure C-1. Results for gross beta analysis from 1974 to current year are plotted.

Gamma Spectrometry Gamma spectroscopy was performed on each of the 32 quarterly composite samples. Beryllium-?, attributed to cosmic ray activity in the atmosphere, was detected -in all 24 indicator location composites at concentrations ranging from 66 E-3 to 149 E-3 pCi/m3 with an average concentration of 98 E-3 pCi/m 3 , and in t~e eight control location composites ranging in concentration from 78 to 143 E-3 pCi/m 3 with an average concentration of 97 E-3 pCi/m 3 .

The maximum preoperational level detected was 85 E-3 pCi/m 3 with an average concentration of 74 E-3 pCi/m3 . (Table C-2, Appendix C)

All othe*r gam.ma emitte_rs were less than the LLD.

2. Air Iodine

Filtered air iodine samples were collected weekly at six indicator locations (382, 12E1, 1281, 981, 1083 and 1386) and two control locations (6G1 and 8G1). Each of the samples collected for the year were analyzed for 1-131 .

lodine-131 lodine-131 was not detected in any indicator location samples or control location samples. Preoperational data is not available for comparison. (Table C-3, Appendix C)

B. Direct Radiation Ambient radiation levels in the environs were measured with a pair of optically stimulated luminescent dosimeters (OSLO) composed of aluminum oxide crystals supplied and processed by Landauer.

Packets containing OSLDs for quarterly exposure were placed in the owner-controlled area and around the Site at various distances and in each land based meteorological sector. Emphasis was placed on special interest areas such as population centers, nearby residences, and schools.

A total of 57 locations were monitored for direct radiation during 2015, including 32 site boundary locations, 14 outer distance locations, six special interest locations and five control locations.

The average dose rate for the 208 indicator dosimeters was 20.2 milliroentgen per standard quarter. The average control dose rate for the 20 control dosimeters was 16.1 milliroentgen per standard quarter.

The preoperational average for the quarterly direct radiation readings was 17.6 milliroentgen per standard quarter. The results of the direct radiation measurements for 2015 confirmed that the radiation levels in the vicinity of the SSES were similar to previous years. (Table C-4, Appendix C); Figure C Ambient Radiation Levels Based on Environmental Dosimetry Data from 1973 to current year are plotted as quarterly averages.

C. Terrestrial Terrestrial REMP sampling includes the collection of milk, groundwater, drinking water, vegetation and soil samples.

1. Milk Milk samples were collected semi-monthly when cows were on pasture and monthly when cows were not grazing on open pasture. Animals are considered on pasture from April to October of each year. Samples were collected in new polyethylene containers and transported in ice chests with no preservatives added to the milk.

Milk samples were collected at local dairy farms from 2 indicator locations (5E2 .and 13E3) and one control location (10G1). Each sample was analyzed for 1-131 and gamma emitters.

lodine-131 lodine-131 was not detected above minimum detectable concentration in any of the 60 samples analyzed.

Preoperational data is not available for comparison. (Table C-5, Appendix C); Figure C lodine-131 Activity in Milk results from 1976 to 2015 are plotted.

Gamma Spectrometry Naturally occurring K-40 was detected in all 60 samples with concentrations for the 40 indicator location samples ranging from 1,331 to 1,580 pCi/L with an average concentration of 1,380 pCi/L, and the 20 control locatio.n sample concentrations ranging from 1,039 to 1,514 pCi/L pCi/L with an average concentration of 1,380 pCi/L. The maximum preoperational level detected was 1,500 pCi/L with an average concentration of 1,358 pCi/L. Naturally occurring Th-228 was not detected in any of the samples. Preoperatiorial data is not available for comparison. (Table C-5, Appendix C)

All other gamma emitters were less than the LLD.

2. Groundwater An expanded groundwater monitoring network was initiated in 2006 for the SSES as part of a site-wide hydrogeological investigation in accordance with the Nuclear Energy Institute (NEI) Groundwater Protection Initiative (GPI). The additional groundwater monitoring wells are sampled as part of the Radiological Environmental Monitoring Program (REMP) to regularly assess groundwater quality and provides early detection of any inadvertent leaks or spills of radioactive materials that could reach groundwater. Groundwater is sampled quarterly and analyzed for H-3 and gamma activity.

Additionally, precipitation sampling was initiated in 2007 and analyzed for H-3 activity to assess the influence of station airborne H-3 emissions on groundwater H-3 activities.

Precipitation washout monitoring data is not used in dose calculations; however, the data does give a gross indication of H-3 concentrations which makes its way into surface water and soil where it eventually seeps into shallow groundwater. The annual average H-3 concentration in precipitation, groundwater monitoring wells and surface water is summarized in Table C-7 and graphically depicted in Figure C Annual Average Tritium Activity (pCi/L) in precipitation, Surface Water Versus Ground Water.

Ground water samples were collected quarterly at 14 indicator locations (282, 484, 6810, 1182, 183, 488, 489, 884, 7810, 1387, 288, 6S11A, 6812 and 7811) and one control location, (12F3). Each sample was analyzed for H-3 and gamma emitters.

Tritium Tritium activity was detected above the minimum detectable concentration in 7 of the 54 indicator location samples with concentrations ranging from 145 to 272 pCi/L with an average concentration of 197 pCi/L. No Tritium was detected in any of the four control location samples. The maximum preoperational level detected was 119 pCi/L. (Table C-6, Appendix C); Figure C Annual Average Tritium Activity (pCi/L) in precipitation, Surface Water Versus Ground Water results from 2007 to 2015 are plotted.

Gamma Spectrometry Naturally occurring K-40 was detected in five of the 54 indicator samples. Sample concentrations ranged from 43 to 174 pCi/L with an average concentration of 78 pCi/L. No K-40 was

_detected in the control location samples.

Naturally occurring Th-228 was detected in one of the 54 indicator samples at a concentration of 13 pCi/L. No Th-228 was detected in the control location samples. Preoperational data is not available for comparison. (Table C-6, Appendix C)

All other gamma emitters were less than the LLD.

3. Drinking Water Drinking water samples were collected monthly from one location (12H2). Each sample was analyzed for gross beta, H-3 and gamma emitters.

Gross Beta Gross beta activity was detected in six of the 12 drinking water samples. Sample concentrations ranged from 1.8 to 2.8 pCi/L with an average concentration of 2.2 pCi/L. The maximum preoperational level detected was 2.8 pCi/L with an average concentration of 1.8 pCi/L. (Table C-8, Appendix C); Figure C Gross Beta Activity in Drinking Water results from 1977 to 2015 are plotted.

Tritium Tritium activity was not detected in any of the samples. The maximum preoperational level detected was 194 pCi/L with an average of 132 pCi/L. (Table C-8, Appendix C)

4. Food Products Food products from four indicator locations (3S3, 12F7, 11 D1, and 11 S6) and one control location (8G1) were collected throughout the growing season. All samples (vegetable and

\

broadleaf) were analyzed for gamma emitters and included green beans, potatoes, field corn, kale, swiss chard and collards.

Gamma Spectrometry Naturally occurring Be-7, attributed to cosmic ray activity in the atmosphere, was detected in 17 of the 30 indicator location samples with concentrations ranging from 242 to 639 pCi/kg wet with an average concentration of 435 pCi/kg wet, and in three of the control location*samples with concentrations ranging from 293 to 501 pCi/kg wet with an average concentration of 401 pCi/kg wet. Preoperational data is not available for comparison.

Naturally occurring K-40 was detected in all 34 indicator location *samples with concentrations ranging from 2,262 to 12,963 ~Ci/kg wet with an average concentration of 5,460 pCi/kg wet, and in all 15 control location samples with concentrations rangi.ng from 2,881 to 6,932 pCi/kg wet with an average concentration of 4,763 pCi/kg wet. The maximum preoperational level detected was 4,800 pCi/kg wet with an average concentration of 2, 140 pCi/kg wet.

Naturally occurring Ac-228 was not detected in any of the indicator or control locations. Preoperational data is not available for comparison.

Naturally occurring Th-228 was not detected in any of the indicator or control locations. Preoperational data is not available for comparison. {Table C-9, Appendix C)

All other gamma emitters were less than the LLD.

5. Soil Soil samples were collected annually from two indicator locations (12S1 and 10S3) and one control location (8G1).

Each sample was analyzed for gamma emitters.

Gamma Spectrometry Naturally occurring K-40 was detected in both indicator location samples at concentrations ranging from 8,897 to 12,930 pCi/kg dry with an average concentration of 11, 139 pCi/kg dry, and in both of the control location samples at concentrations ranging from 9,920 to 9,920 pCi/kg dry with an average concentration of 9,742 pCi/kg dry. The maximum preoperational level detected was 1, 100 pCi/kg dry with an average concentration of 9,800 pCi/kg dry.

Cesium-137 was not detected in any of the indicator location or control location samples. The maximum preoperational level detected was 1,200 pCi/kg dry with an average concentration of 700 pCi/kg dry.

Naturally occurring Ra-226 was detected in two of the indicator location samples at concentrations ranging from 2,452 to 2,912 pCi/kg dry with an average concentration of 2,682 pCi/kg dry, and in one of the control location samples at a concentration of 3,284pCi/kg dry. The maximum preoperational level detected was 1,300 pCi/kg dry with an average concentration of 1, 100 pCi/kg dry.

Naturally occurring Ac-228 was detected in three of the indicator location samples at concentrations ranging from 816 to 1,243 pCi/kg dry with an average concentration of 1,017 pCi/kg dry, and in all of the control location samples at "concentrations ranging from 717 to 1,059 pCi/kg dry with an

'*, average concentration of 888 pCi/kg dry. Preoperational data is not available for comparison.

Naturally occurring Th-228 was detected in all of the four indicator location samples at concentrations ranging from 709 to 963 pCi/kg dry and an average concentration of 829 pCi/kg dry, and in both of the control location samples at concentrations ranging from 932 to 1,025 pCi/kg dry with an average concentration of 979 pCi/kg dry. The maximum preoperational level detected was 1,300 pCi/kg dry with an average concentration of 1,100 pCi/kg dry. (Table C-10, Appendix C)

All other gamma emitters were less than the LLD.

D. Aquatic Aquatic samples include surface water, fish and sediment samples.

1. Surface Water Surface water samples were collected routinely at six indicator locations (6S5, 2S7, LTAW, 4S7, 5S12 and 7S12) and one control location (6S6). Each sample was analyzed for H-3 and gamma emitters.

Tritium Tritium activity was detected in 16 of 40 indicator location samples with concentrations ranging from 179 to 4,340 pCi/L with an average concentration of 1,492 pCi/L. The range of H-3 levels in surface water are biased high due to inclusion of samples from the cooling tower blowdown line (CTBD; location 2S7). Routine station operation includes infrequent batch releases of slightly radioactive water which are discharged into the CTBD. When the H-3 concentration from CTBD samples is averaged with those obtained from Susquehanna River downstream monitoring locations, the result is an overall indicator location average that is higher than the actual average H-3 levels of the downstream river water. No radioactivity attributable to station operations was identified above analysis detection levels in any samples from the Susquehanna River in 2015. Tritium was not detected in any of the control location samples. The maximum preoperational level detected was 319 pCi/L, with an average concentration of 140 pCi/L. (Table C-11, Appendix C) [Figure C Tritium Activity in Surface Water, results from 1972 to 2015 are plotted.]

Gamma Spectrometry Naturally occurring K-40 was detected in 4 of the 40 indicator location samples with concentrations ranging from 39 to 104 pCi/L with an average concentration of 64 pCi/L, and in two of the 13 control location samples with concentrations ranging from 38 to 44 pCi/L with an average concentration of 41 pCi/L.

Preoperational data is not available for comparison.

Naturally occurring Th-228 was not detected in any of the indicator or control locations. Preoperational data is not available for comparison. (Table C-11, Appendix C) lodine-131 lodine-131 was not detected in any of the indicator or control samples. The maximum preoperational level detected was 0.43 pCi/L, with an average concentration of 0.33 pCi/L. (Table C-11, Appendix C)

All other gamma emitters were less than the LLD.

2. Fish Edible species of fish were collected in the spring and fall of 2015 at two indicator locations (IND [Susquehanna River] and LTAW) and one control location (2H [Susquehanna River]).

Each sample was analyzed for gamma emitters.

Gamma Spectrometry Naturally occurring K-40 was detected in all seven indicator location samples at concentrations ran.ging from 2,277 to 4,493 pCi/kg wet with an average concentration of 3,441 pCi/kg wet, and in all six control location samples at concentrations ranging from 3,306 to 4,723 pCi/kg wet with an average concentration of 3,632 pCi/kg wet. The maximum preoperational level detected was 3,600 pCi/kg dry with an average concentration of 3,871 pCi/kg dry. (Table C-12, Appendix C)

All other gamma emitters were less than the LLD.

3. Shoreline Sediment Sediment samples were collected from the Susquehanna River in the spring and fall at two indicator locations (78 and 12F) and one control location (28). Each sample was analyzed for gamma emitters.

Gamma Spectroscopy Naturally occurring K-40 was detected in all four of the indicator location samples at concentrations ranging from 9,673 to 13,230 pCi/kg dry with an average concentration of 12, 136 pCi/kg dry, and in both of the control location samples with concentrations ranging from 9,811 to 13,360 pCi/kg dry with an average concentration of 11,586 pCi/kg dry. The maximum preoperational level detected was 11,000 pCi/kg dry with an average concentration of 8,500 pCi/kg dry.

Cesium-137 was not detected in any of the samples. The maximum preoperational level detected was 210 pCi/kg dry with an average concentration of 110 pCi/kg dry.

Naturally occurring Ra-226 was not detected in any of the indicator location samples, but found in one of the three control location samples with a concentration of 2,245 p/Ci/kg. The maximum preoperational level detected was 1,900 pCi/kg dry with an average concentration of 700 pCi/kg dry.

Naturally occurring Ac-228 was detected in all four indicator location samples at concentrations ranging from 795 to 1,229 pCi/kg dry with an average concentration of 1,060 pCi/kg dry,

. and in both of the control location samples at concentrations ranging from 946 to 1,297 pCi/kg dry with an average concentration of 1, 130 pCi/kg dry. Preoperational data is not available for comparison. (Table C-13, Appendix C)

Naturally occurring Th-228 was detected in all of the four indicator location samples at concentrations ranging from 787 to 1,272 pCi/kg dry with an average concentration of 1,024 pCi/kg dry, and in all three of the control location samples at concentrations ranging from 1,012 and 1,282 pCi/kg dry with an average concentration of 1,147 pCi/kg dry.

All other gamma emitters were less than the LLD.

E. Land Use Census SYNOPSIS OF 2015 LAND USE CENSUS Ecology Ill, Inc. conducted a Land Use Census during the 2015 growing season around SSES to comply with the ODCM. The purpose of the survey was to doc1o1ment the nearest milk animal, residence and garden greater than 50 m2 (approximately 500 ft2) producing broad leaf vegetation within a distance of 8 km (approximately 5 miles) in each of the 16 meteorological sectors surrounding the SSES.

VI. Conclusions The Radiological Environmental Monitoring Program for SSES was conducted during 2015 in accordance with the SSES TRM and ODCM. The LLD values required by the TRM and ODCM were achieved for this reporting period (See Appendix A and Appendix C). The objectives of the program were also met during this period. The data collected assists in demonstrating that SSES was operated in compliance with TRM and ODCM requirements.

The concentration of radioactive material in the environment that could be attributable to SSES operations was only a small fraction of the concentration of naturally occurring and man-made radioactivity. Since these results were comparable to the results obtained during the preoperational phase of the program, which ran from 1972 to 1982, and with historical results collected since commercial operation, it is concluded that operation of the SSES had no significant radiological impact on the health and safety of the public or the environment.

From the results obtained, it can be concluded that the levels and fluctuations of radioactivity in environmental samples were as expected for the environment surrounding the SSES.

APPENDIX 8 SAMPLE DESIGNATION AND LOCATIONS B-1

')

SAMPLE DESIGNATION All distances from the SSES to monitoring locations are measured from the standby gas treatment vent at 44200/N34117 (Pa. Grid System). The location codes are based on both distance and direction from the SSES. The letters in the location codes indicate if the monitoring locations are on site (within the site boundary) or, if they are not on site, the approximate distances of the location from the SSES as described below:

s = On site E = 4-5 miles A = < 1 mile F = 5-10 miles B = 1-2 miles G = 10 - 20 miles c = 2-3 miles H = > 20 miles D = 3-4 miles The numbers preceding the letters in the location codes provide the direction of the monitoring locations from the SSES by indicating the sectors in which they are located. A total number of 16 sectors (numbered one through 16) equally divide an imaginary circle on a map of the SSES and its vicinity, with the SSES at the center of the circle. The middle of sector one is directed due North (N). Moving clockwise from sector one, the sector immediately adjacent to sector one is sector two, the middle of which is directed due north, north east (NNE). Continuing to move clockwise the sector number increases to 16, which is the north northwest sector (NNW).

TABLE 8-1 SAMPLING LOCATIONS Specific information about the individual sampling locations are given in Table B-1. Maps B-1 through B-6 show the locations of sampling stations with respect to the Site. A Portable Global Positioning System (GPS) was used to provide the coordinates of sampling locations.

(2) A standard (std.) quarter (qtr.) is considered to be 91.25 days. Results obtained for monitoring periods of other durations are normalized by multiplying them by 91.25/x, where x is the actual duration in days of the period.

(3) Uncertainties for individual monitoring location results are two standard deviations of the elemental doses of four elements from the two dosimeters assigned to each monitoring location, representing the variability between the elemental doses of each of the four dosimeter elements.

(4) No measurement could be made at this location because the dosimeters were lost, stolen, or damaged. Refer to Section Ill, Program Description.
