==SUMMARY==
This Annual Radiological Environmental Operating Report describes the V.C. Summer Environmental Monitoring Program and the program results for the calendar year 2015.
Included are the identification of sample locations, descriptions of environmental sampling and type of analysis. Comparisons of present environmental radioactivity levels and pre-operational environmental data, land use census comparisons of doses calculated from environmental measurements, and a summary of environmental radiological sampling results. Quality assurance practices, sampling deviations and unavailable samples are also discussed.
Sampling activities were conducted as prescribed by the Offsite Dose Calculation Manual (ODCM) for V.C. Summer Nuclear Station (VCSNS) and applicable Health Physics Procedures. Required analyses were performed and detection limits met for required samples with exceptions noted. Samples were collected comprising one thousand two hundred sixty two analyses (1,262) performed to compile the data for the 2015 Environmental Report. Supplemental samples comprising two hundred fifty eight (258) analyses were performed on some media for additional information. Based on the results from the annual land use census, the current number of sampling sites for V.C. Summer Nuclear Station is sufficient.
Concentrations observed in the environment in 2015 from V.C. Summer related radionuclide concentrations were* within the range of concentrations observed in the past. It is therefore concluded that VCSNS operations have no significant radiological impact on the health and safety of the public or the environment.

INTRODUCTION Virgil C. Summer Nuclear Station (VCSNS) utilizes a pressurized water reactor rated at 2900 MWt (990 MWe gross). The station is located adjacent to the Monticello Reservoir near Jenkinsville, South Carolina and approximately 26 miles northwest of Columbia. VCSNS achieved initial criticality on October 22, 1982, reached 50% power December 12, 1982 and 100% power June 10, 1983 following steam generator feedwater modifications. Steam generators were replaced in the fall of 1994. During the ninth refuel the plant was uprated to 2900 MWt (990 MWe gross). VCSNS is currently operating in the 23rd fuel cycle.
VCSNS is operating in conjunction with the adjacent Fairfield Pump Storage Facility (FPSF) which consists of eight reversible pump-turbine units of *50 MWe capacity each.
During periods of off-peak power demand, base load generating capacity is used to pump water from Parr Reservoir to Monticello Reservoir. Monticello Reservoir has a surface area of approximately 6800 acres and lies about 150 feet above Parr Reservoir whose full pool area is approximately 4400 acres. The pump-turbine units operate in the generating mode to meet peak system loads while Monticello Reservoir also provides condenser cooling water for VCSNS. Cooling water intake and discharge structur~s are separated by a jetty to ensure adequate circulation within the reservoir.
VCSNS is located in Fairfield County which, along with Newberry County, makes up
_the principle area within a 10 mile radius of the plant. This area is mainly forest with only about 30% devoted to small farming activities principally producing small grains, feed crops and beef cattle. Significant portions of Lexington and Richland Counties are
* encompassed within the 20 mile radius of the plant and exhibit similar agricultural activities. Columbia, the state capital, is the only large city within the 50 *mile radius of the plant. Small agricultural concerns are predominant, but make up less than 50% of the .land area. The main industrial activity is concentrated around Columbia and is generally greater than 20 miles from the VCSNS.
Liquid effluents from VCSNS are released into the Monticello/Parr Reservoirs at two discharge points: the Circulating Water Discharge Canal (CWDC) and the FPSF Penstocks. Non-nuclear drains are released to the CWDC. Effluent from the liquid waste processing system and processed steam generator blow down are released through the penstocks. Radioactive gaseous effluents from VCSNS are released from two points: the Main Plant Vent and the Reactor Building Purge Exhaust, all considered ground level releases.
Radioactive liquid and gaseous releases from the facility and their potential influence on the surrounding biota and man are the primary concern of the Radiological Environmental Monitoring Program at VCSNS. This report summarizes the results of the Radiological Environmental Monitoring Program conducted during 2015. Data trends, control/indicator and preoperational/operational data inter-comparisons, and other data interpretations are presented.

DESCRIPTION OF THE RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM The Radiological Environmental Monitoring Program is carried out in its entirety by South Carolina Electric and Gas Company. The program has been designed to meet the following general commitments:
            . 1. To analyze selected samples in important anticipated pathways for the qualification and quantification of radionuclides released to the. environment surrounding VCSNS.
: 2. To establish correlations between levels of environmental radioactivity and radioactive effluents from VCSNS operation.
The program utilizes the concepts of control/indicator and preoperational
    /operational inter-comparisons in order to establish the adequacy of radioactivity source
_control and to realistically verify the assessment of environmental radioactivity levels and subsequent radiation dose to man.
Sample media and analysis sensitivity requirements have been established to ensure that the maximum dose pathways are monitored and sensitivities represent a small fraction of annual release limits. Effluent dispersion characteristics, demography, hydrology and land use have been considered in selection of environmental sampling locations. These criteria were used to establish both the preoperational and operational phases of the Radiological Environmental Monitoring Program. Elements of the program monitor the impact of gaseous and liquid effluents released from VCSNS.
Specific methods* used in monitoring the pathways of these effluents which may lead to radiation exposure of the public, based on existing demography, are summarized below in Table 1. Requirements of the Radiological Environmental Monitoring Program are specified in the VCSNS Offsite Dose Calculation Manual (ODCM). Elements of the program monitor the impact of gaseous and liquid effluents released from VCSNS.

Monitoring sites indicative of plant operating conditions are generally located within a 5 mile radius of the plant. Table 6 provides a list of ODCM required sampling locations.
Table 7 provides a list of supplemental sampling locations. Maps showing radiological environmental sampling locations within a radius of approximately 5 *miles from VCSNS are presented as Figures 1-2 through 1-5. Figure 1-1 shows monitoring sites at distances greater than 10 miles from the plant. These locations indicate regional fluctuations in background radiation levels.
In addition to preoperational/operational data inter-comparisons, -control/indicator data inter-comparisons are utilized. This is done to assess the probability that any observed abnormal measurement of radioactivity concentration is due to random or regional fluctuations rather than to a true increase in local environmental radioactivity concentration.
Environmental data is gathered _through multiple types of sampling and measurements at specific locations. Several multiple sampling combinations are in. use around the VCSNS. For example, all air sampling locations serve as environmental dosimetry monitoring locations. At these locations, airborne plant effluents are monitored for gamma immersion dose (noble gases), in addition to air contaminants. Monitoring locations Site 6 (1.0 mi. ESE) and Site 7 (1.0 mi. E) have broadleaf vegetation-gardens for monitoring gaseous effluent deposition (ingestion pathway) in the two sectors having the highest deposition coefficients (D/Q) with real potential for exposure. Monitoring location Site 18 (16.5 mi. S) serves as a control location for direct radiation and Site 40 (11.9 mi.
* SSE) serves as a .control location for garden monitoring.
Liquid effluents are monitored using three different monitoring media (fish, bottom sediment and surface water) at the two most probable affected bodies of water around the plant: Site 21, Parr Reservoir (2.7 mi. SSW) and Site 23,* Monticello Reservoir (0.5 mi.
ESE). The control location for liquid effluent comparisons is at Site 22, Neal Shoals (26.0 mi. NNW) on the Broad River.:
Quality of analytical measurements is demonstrated by participation in a laboratory inter-comparison program. Results of the inter-comparison program with an outside vendor and VCSNS Count Room were satisfactory in 2015. The results of each of these quality control checks of the Radiological Environmental Monitoring -program verify the technical credibility of analytical data generated and reported by the program.

LAND USE CENSUS Annually a land use census is performed within a 5 mile radius of VCSNS to verify the adequacy of sample locations. In addition, the location of the maximum exposed individual (MEI) is identified. The results of the land use census performed in 2015 are included in Table 4. A verification of the maximum exposed individual location is presented in Table 5. Identification of the highest offsite dose locations was performed by calculating a hypothetical dose based on predicted VCSNS source term from the Operating License Environmental Report and 2015 meteorological data. Exposure pathways used in the analysis were those identified during the land use census.
The location and pathway presently used in the ODCM for offsite organ dose calculations (E 1.1 miles - residence/gan;:len) was found to have a calculated dose of 2.35E+O mrem/year. In addition, the ODCM required environmental gardens (ESE 1.0 and E 1.0 mile) were found to have a calculated dose of 2.07E+O and 2.98E+O mrem/year.
There were no milking animals or dairy activity found within 5 kilometers of VCSNS.
Therefore, changes to the ODCM gaseous effluent calculations or garden sample locations are not indicated.
MONITORING RESULTS AND DISCUSSION The results of the Radiological Environmental Monitoring Program for 2015 are summarized in Table 8. For comparison, preoperational data are summarized in Table 9.
The Radiological Environmental Program attained a program compliance rate of approximately 99.4%. A listing of program exceptions and their respective causes are included in Table 11. Analysis of the impact of these omissions verified that program quality has not been affected.
Corbicula harvest for possible human consumption was observed in Lake Monticello in 2005. Since that time Corbicula analysis has been incorporated in the Supplemental Sampling Program. Samples were collected and analyzed for gamma emitting isotopes.
No measurable gamma emitting nuclides were detected above minimum detectable activity (MDA).
Gross beta activities measured in air particulate samples collected at indicator locations around VCSNS were consistent with preoperational levels and not statistically different from control locations. The highest site-specific mean activity (2.34E-2 pCi/m 3 )
was measured at indicator location Site 7 (Lab Garden 1.0 mi. E). The results indicate that
* the operation of VCSNS has not contributed to detectable increases of airborne gross beta activity in the environment.
Gamma spectroscopy measurements of composited air particulate samples and activated charcoal cartridges support the gross beta activity trend. Only natural background activities were detected. The highest MDA levels for 134Cs, 137 Cs and 131 1 were 2.54E-3, 2.58E-3 and 1.59E-2 pCi/m 3 , respectively. The average maximum results support the gaseous effluent release data reported in the 2015 Annual Radiological Effluent Release Report for VCSNS. 99.4% of the required indicator/control air samples were collected.

Environmental dosimetry measurements did not differ significantly .from preoperational measurements. Indicator and control dosimetry measurements also showed no appreciable differences. Comparison with other operational years shows no statistically significant difference. Monitoring location Site 4 (Fairfield Hydro 1.2 mi. WNW) was the indicator location showing the highest mean exposure rate of 1.28E+1 µR/hr. This is similar to the 2014 value of 1.14E+1 µR/hr and consistent with the highest mean exposure rate of 1.40 E+1 µR/hr measured during the preoperational period. 99% of the required TLDs were collected.
Gamma spectroscopy measurements of surface water samples did not indicate the presence of activated corrosion or fission products above the respective MDA for indicator sites. Tritium analysis indicated the presence of tritium above MDA in three samples at Site 21 (Parr Reservoir 2.7 mi. SSW), at concentrations of 7.65E+2 pCi/L, 8.04E+2 pCi/L, and 6.25E+2 pCi/L. The presence of tritium was also detected in three samples at Site 23 (Monticello Reservoir 0.5 mi. ESE). The tritium, concentrations were 6.86E+2 pCi/L, 7.81E+2 pCi/L, and 9.65E+2 pCi/L. 100% of indicator/control surface water samples were collected.
Gamma spectroscopy measurements of the ODCM required ground water samples did not indicate the presence of activated corrosion or fission products above the respective MDAs. Tritium was detected in four supplemental ground water samples at Site 123 (NPDES Well GW-16 0.34 SSE), at concentrations of 1.79E+3 pCi/L, 1.55E+3 pCi/L, 2.26E+3 pCi/L, and 3. 79E+3 pCi/L. 100% of indicator/control ground water samples were collected.
Gamma spectroscopy measurements of drinking water samples collected from the Jenkinsville water supply and Site 17 (Columbia Water Works 25.0 mi. SE) did not indicate the presence of activated corrosion or fission product activity above the respective MDAs.
Tritium analysis indicated the presence of tritium above MDA in four samples taken at Site 17 (Columbia Water Works 25.0 mi. SE) at concentrations of 6.37E+2 pCi/L, 6.54E+2 pCi/L, 8.01 E+2 pCi/L, and 5. 71 E+2 pCi/L.. The highest indicator and control site-specific gross beta activity was measured at Site 28 (New Nuclear Deployment 2.6 mi. SSE) at a level of 4.30E+O pCi/I. 97.2% of indicator/control drinking water samples were collected.
There were no milk samples collected in 2015. Milk sampling is required to be performed at the three highest dose locations within 5 kilometers of the plant or at 5 to 8 kil.ometers of the plant, if doses are calculated to be greater than 1 mrem per year.
Presently there are no locations meeting this criteria for indicator dairies. The closest dairy is approximately 8 kilometers from the plant (see Table 4). Milk samples will be obtained from this dairy if gaseous releases from the plant exceed 5% of quarterly organ dose limits or radionuclides (attributed to the operation of VCSNS) are detected in broadleaf vegetation, grass or air samples at concentrations greater than required LLDs.

Gamma spectroscopy measurement of supplemental grass samples collected indicated 137Cs in 3 of 12 samples at Site 2 (transmission line 1.2 mi. SW) at concentrations of 2.18E+1 pCi/kg, 2.35E+1 pCi/kg, and 2.85E+1 pCi/kg. The maximum preoperational control activity was 3.40E+2 pCi/kg. 100% of indicator/control supplemental grass samples were collected.
l Gamma spectroscopy measurements of the broadleaf samples collected did not indicate the presence of activated corrosion or fission products above the respective MDAs. All of the required indicator/control broadleaf samples were collected.
Gamma spectroscopy measurements of all non-leafy (other vegetation) supplemental samples collected did not indicate the presence of activated corrosion or fission products above the respective MDA.
Gamma spectroscopy measurements of all fish samples collected did not indicate the presence of activated corrosion or fission products above the respective MDA. All of the required indicator/control fish samples were collected.
Gamma spectroscopy measurements of sediment samples indicated the detection of 137 Cs in 2 of 4 indicator samples. Site 21 (Parr Res. 2.7 mi. SSW) at concentrations of 2.27E+2 and 1.28E+2 pCi/kg were detected. 137 Cs was also detected in 2 of 2 control samples taken at Site 22 (Neal Shoals 26 mi. NNW) at concentrations of 5.99E+1 and 5.70E+1 pCi/kg. All required indicator/control sediment samples were collected.

CONCLUSION As in previous years of VCSNS operation, the presence of fission product activity attributed to residual fallout from atmospheric weapons testing and the Chernobyl accident were detected in environmental media including sediment and grass.
No detectable fission or activation product activity attributed to VCSNS operations was observed in environmental media with the exception of:
* Tritium in four drinking water samples taken at site 17 (Columbia Water Works 25.0 mi. SE) and two supplemental samples taken at site 99 (Nuclear Operations Bldg). Concentrations were well below drinking water standards.
* Co-60 and Cs-137 was detected in one supplemental soil sample taken at Site 25 (Fairfield Pumped Storage Penstocks 0.9 WNW).
* Tritium in all four supplemental ground water samples taken at Site 123 (NPDES Well GW-16 0.34 mi. SSE).
The dose calculated for the maximum exposed individual will not result in observable effect on the ecosystem or general public. The results of the Radiological Environmental Monitoring Program, therefore, substantiate the continuing adequacy of source control at VCSNS and conformance of station operation to 10 CFR 50, Appendix I design objectives.

Table 8 (cont) - Radiological Environmental Monitoring Program Summary for 2015 Footnotes
: 1. Includes indicator and control analyses. Site 8, Air Particulates and Air Radioiodines are included as indicators. Does not include other supplemental samples.
: 2. Values given are maximum MDA values for indicator locations calculated from the program data analyses. The maximum acceptable LLD values allowed from NRG guidelines are given in parentheses.
: 3. Mean and range are based on detectable measurements only. The fractions of detectable measurements (i.e., number of positive results/total number of measurements) at specific locations are indicated in parentheses.
: 4. Any confirmed measured level of radioactivity in any environmental medium that exceeds the reporting requirements of ODCM, Section 1.4.1.2.
: 5. Detection sensitivity is approximately 10 mrem/yr (1.0 &#xb5;R/hr).
: 6. Elevated levels of 214 Pb and 214 Bi were observed in Jenkinsville drinking water samples.
The values are not reported here because they are naturally occurring (do not originate from VCSNS) and furnish no quantifiable information of interest.
: 7. Fish include 3 groups (Bass, Bream/Crappie, Catfish/Carp.)
: 8. Elevated levels of 214Pb and 214 Bi plus other 226 Ra daughter products and 228Ac plus other 232 Th daughter products were observed in all sediment samples. The values are not reported here because they are naturally occurring (do not originate from VCSNS) and furnish no quantifiable information of interest.

Table 9 (Cont.)- Radiological Environmental Monitoring Program Preoperational (Baseline) Summary Footnotes
: 1. Values given are MDA values calculated from the program data analyses with maximum acceptable LLD values allowed from NRG guidelines given in parenthe.ses.
: 2. Mean and range are based on detectable measurements only. The fractions of detectable measurements at specific locations are indicated in parentheses.
: 3. A non-routine measurement is any confirmed measured level of radioactivity in an environmental medium that exceeds the reporting requirements of VCSNS ODCM, Section 1.4.1.2.
: 4. The baseline values are high because of the fallout from the* Chinese bomb test in 1980.
The first set of data reflects the 1981 baseline. The second set of data reflects the 1982 baseline, essentially free of bomb test fallout. The 1982 data covers the period 1/1/82 -
10/22/82.
: 5. Detection sensitivity is approximately 5 mrem/yr (0.5 &#xb5;R/hr) determined from the analyses of five years of preoperational data.
: 6.
* No control location was specified for drinking water during the preoperational monitoring period.
: 7. Inconclusive data.

SUMMARY

This Annual Radiological Environmental Operating Report describes the V.C. Summer Environmental Monitoring Program and the program results for the calendar year 2015.

Included are the identification of sample locations, descriptions of environmental sampling and type of analysis. Comparisons of present environmental radioactivity levels and pre-operational environmental data, land use census comparisons of doses calculated from environmental measurements, and a summary of environmental radiological sampling results. Quality assurance practices, sampling deviations and unavailable samples are also discussed.

Sampling activities were conducted as prescribed by the Offsite Dose Calculation Manual (ODCM) for V.C. Summer Nuclear Station (VCSNS) and applicable Health Physics Procedures. Required analyses were performed and detection limits met for required samples with exceptions noted. Samples were collected comprising one thousand two hundred sixty two analyses (1,262) performed to compile the data for the 2015 Environmental Report. Supplemental samples comprising two hundred fifty eight (258) analyses were performed on some media for additional information. Based on the results from the annual land use census, the current number of sampling sites for V.C. Summer Nuclear Station is sufficient.

Concentrations observed in the environment in 2015 from V.C. Summer related radionuclide concentrations were* within the range of concentrations observed in the past. It is therefore concluded that VCSNS operations have no significant radiological impact on the health and safety of the public or the environment.

INTRODUCTION Virgil C. Summer Nuclear Station (VCSNS) utilizes a pressurized water reactor rated at 2900 MWt (990 MWe gross). The station is located adjacent to the Monticello Reservoir near Jenkinsville, South Carolina and approximately 26 miles northwest of Columbia. VCSNS achieved initial criticality on October 22, 1982, reached 50% power December 12, 1982 and 100% power June 10, 1983 following steam generator feedwater modifications. Steam generators were replaced in the fall of 1994. During the ninth refuel the plant was uprated to 2900 MWt (990 MWe gross). VCSNS is currently operating in the 23rd fuel cycle.

VCSNS is operating in conjunction with the adjacent Fairfield Pump Storage Facility (FPSF) which consists of eight reversible pump-turbine units of *50 MWe capacity each.

During periods of off-peak power demand, base load generating capacity is used to pump water from Parr Reservoir to Monticello Reservoir. Monticello Reservoir has a surface area of approximately 6800 acres and lies about 150 feet above Parr Reservoir whose full pool area is approximately 4400 acres. The pump-turbine units operate in the generating mode to meet peak system loads while Monticello Reservoir also provides condenser cooling water for VCSNS. Cooling water intake and discharge structur~s are separated by a jetty to ensure adequate circulation within the reservoir.

VCSNS is located in Fairfield County which, along with Newberry County, makes up

_the principle area within a 10 mile radius of the plant. This area is mainly forest with only about 30% devoted to small farming activities principally producing small grains, feed crops and beef cattle. Significant portions of Lexington and Richland Counties are

  • encompassed within the 20 mile radius of the plant and exhibit similar agricultural activities. Columbia, the state capital, is the only large city within the 50 *mile radius of the plant. Small agricultural concerns are predominant, but make up less than 50% of the .land area. The main industrial activity is concentrated around Columbia and is generally greater than 20 miles from the VCSNS.

Liquid effluents from VCSNS are released into the Monticello/Parr Reservoirs at two discharge points: the Circulating Water Discharge Canal (CWDC) and the FPSF Penstocks. Non-nuclear drains are released to the CWDC. Effluent from the liquid waste processing system and processed steam generator blow down are released through the penstocks. Radioactive gaseous effluents from VCSNS are released from two points: the Main Plant Vent and the Reactor Building Purge Exhaust, all considered ground level releases.

Radioactive liquid and gaseous releases from the facility and their potential influence on the surrounding biota and man are the primary concern of the Radiological Environmental Monitoring Program at VCSNS. This report summarizes the results of the Radiological Environmental Monitoring Program conducted during 2015. Data trends, control/indicator and preoperational/operational data inter-comparisons, and other data interpretations are presented.

DESCRIPTION OF THE RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM The Radiological Environmental Monitoring Program is carried out in its entirety by South Carolina Electric and Gas Company. The program has been designed to meet the following general commitments:

. 1. To analyze selected samples in important anticipated pathways for the qualification and quantification of radionuclides released to the. environment surrounding VCSNS.

2. To establish correlations between levels of environmental radioactivity and radioactive effluents from VCSNS operation.

The program utilizes the concepts of control/indicator and preoperational

/operational inter-comparisons in order to establish the adequacy of radioactivity source

_control and to realistically verify the assessment of environmental radioactivity levels and subsequent radiation dose to man.

Sample media and analysis sensitivity requirements have been established to ensure that the maximum dose pathways are monitored and sensitivities represent a small fraction of annual release limits. Effluent dispersion characteristics, demography, hydrology and land use have been considered in selection of environmental sampling locations. These criteria were used to establish both the preoperational and operational phases of the Radiological Environmental Monitoring Program. Elements of the program monitor the impact of gaseous and liquid effluents released from VCSNS.

Specific methods* used in monitoring the pathways of these effluents which may lead to radiation exposure of the public, based on existing demography, are summarized below in Table 1. Requirements of the Radiological Environmental Monitoring Program are specified in the VCSNS Offsite Dose Calculation Manual (ODCM). Elements of the program monitor the impact of gaseous and liquid effluents released from VCSNS.

Monitoring sites indicative of plant operating conditions are generally located within a 5 mile radius of the plant. Table 6 provides a list of ODCM required sampling locations.

Table 7 provides a list of supplemental sampling locations. Maps showing radiological environmental sampling locations within a radius of approximately 5 *miles from VCSNS are presented as Figures 1-2 through 1-5. Figure 1-1 shows monitoring sites at distances greater than 10 miles from the plant. These locations indicate regional fluctuations in background radiation levels.

In addition to preoperational/operational data inter-comparisons, -control/indicator data inter-comparisons are utilized. This is done to assess the probability that any observed abnormal measurement of radioactivity concentration is due to random or regional fluctuations rather than to a true increase in local environmental radioactivity concentration.

Environmental data is gathered _through multiple types of sampling and measurements at specific locations. Several multiple sampling combinations are in. use around the VCSNS. For example, all air sampling locations serve as environmental dosimetry monitoring locations. At these locations, airborne plant effluents are monitored for gamma immersion dose (noble gases), in addition to air contaminants. Monitoring locations Site 6 (1.0 mi. ESE) and Site 7 (1.0 mi. E) have broadleaf vegetation-gardens for monitoring gaseous effluent deposition (ingestion pathway) in the two sectors having the highest deposition coefficients (D/Q) with real potential for exposure. Monitoring location Site 18 (16.5 mi. S) serves as a control location for direct radiation and Site 40 (11.9 mi.

  • SSE) serves as a .control location for garden monitoring.

Liquid effluents are monitored using three different monitoring media (fish, bottom sediment and surface water) at the two most probable affected bodies of water around the plant: Site 21, Parr Reservoir (2.7 mi. SSW) and Site 23,* Monticello Reservoir (0.5 mi.

ESE). The control location for liquid effluent comparisons is at Site 22, Neal Shoals (26.0 mi. NNW) on the Broad River.:

Quality of analytical measurements is demonstrated by participation in a laboratory inter-comparison program. Results of the inter-comparison program with an outside vendor and VCSNS Count Room were satisfactory in 2015. The results of each of these quality control checks of the Radiological Environmental Monitoring -program verify the technical credibility of analytical data generated and reported by the program.

LAND USE CENSUS Annually a land use census is performed within a 5 mile radius of VCSNS to verify the adequacy of sample locations. In addition, the location of the maximum exposed individual (MEI) is identified. The results of the land use census performed in 2015 are included in Table 4. A verification of the maximum exposed individual location is presented in Table 5. Identification of the highest offsite dose locations was performed by calculating a hypothetical dose based on predicted VCSNS source term from the Operating License Environmental Report and 2015 meteorological data. Exposure pathways used in the analysis were those identified during the land use census.

The location and pathway presently used in the ODCM for offsite organ dose calculations (E 1.1 miles - residence/gan;:len) was found to have a calculated dose of 2.35E+O mrem/year. In addition, the ODCM required environmental gardens (ESE 1.0 and E 1.0 mile) were found to have a calculated dose of 2.07E+O and 2.98E+O mrem/year.

There were no milking animals or dairy activity found within 5 kilometers of VCSNS.

Therefore, changes to the ODCM gaseous effluent calculations or garden sample locations are not indicated.

MONITORING RESULTS AND DISCUSSION The results of the Radiological Environmental Monitoring Program for 2015 are summarized in Table 8. For comparison, preoperational data are summarized in Table 9.

The Radiological Environmental Program attained a program compliance rate of approximately 99.4%. A listing of program exceptions and their respective causes are included in Table 11. Analysis of the impact of these omissions verified that program quality has not been affected.

Corbicula harvest for possible human consumption was observed in Lake Monticello in 2005. Since that time Corbicula analysis has been incorporated in the Supplemental Sampling Program. Samples were collected and analyzed for gamma emitting isotopes.

No measurable gamma emitting nuclides were detected above minimum detectable activity (MDA).

Gross beta activities measured in air particulate samples collected at indicator locations around VCSNS were consistent with preoperational levels and not statistically different from control locations. The highest site-specific mean activity (2.34E-2 pCi/m 3 )

was measured at indicator location Site 7 (Lab Garden 1.0 mi. E). The results indicate that

  • the operation of VCSNS has not contributed to detectable increases of airborne gross beta activity in the environment.

Gamma spectroscopy measurements of composited air particulate samples and activated charcoal cartridges support the gross beta activity trend. Only natural background activities were detected. The highest MDA levels for 134Cs, 137 Cs and 131 1 were 2.54E-3, 2.58E-3 and 1.59E-2 pCi/m 3 , respectively. The average maximum results support the gaseous effluent release data reported in the 2015 Annual Radiological Effluent Release Report for VCSNS. 99.4% of the required indicator/control air samples were collected.

Environmental dosimetry measurements did not differ significantly .from preoperational measurements. Indicator and control dosimetry measurements also showed no appreciable differences. Comparison with other operational years shows no statistically significant difference. Monitoring location Site 4 (Fairfield Hydro 1.2 mi. WNW) was the indicator location showing the highest mean exposure rate of 1.28E+1 µR/hr. This is similar to the 2014 value of 1.14E+1 µR/hr and consistent with the highest mean exposure rate of 1.40 E+1 µR/hr measured during the preoperational period. 99% of the required TLDs were collected.

Gamma spectroscopy measurements of surface water samples did not indicate the presence of activated corrosion or fission products above the respective MDA for indicator sites. Tritium analysis indicated the presence of tritium above MDA in three samples at Site 21 (Parr Reservoir 2.7 mi. SSW), at concentrations of 7.65E+2 pCi/L, 8.04E+2 pCi/L, and 6.25E+2 pCi/L. The presence of tritium was also detected in three samples at Site 23 (Monticello Reservoir 0.5 mi. ESE). The tritium, concentrations were 6.86E+2 pCi/L, 7.81E+2 pCi/L, and 9.65E+2 pCi/L. 100% of indicator/control surface water samples were collected.

Gamma spectroscopy measurements of the ODCM required ground water samples did not indicate the presence of activated corrosion or fission products above the respective MDAs. Tritium was detected in four supplemental ground water samples at Site 123 (NPDES Well GW-16 0.34 SSE), at concentrations of 1.79E+3 pCi/L, 1.55E+3 pCi/L, 2.26E+3 pCi/L, and 3. 79E+3 pCi/L. 100% of indicator/control ground water samples were collected.

Gamma spectroscopy measurements of drinking water samples collected from the Jenkinsville water supply and Site 17 (Columbia Water Works 25.0 mi. SE) did not indicate the presence of activated corrosion or fission product activity above the respective MDAs.

Tritium analysis indicated the presence of tritium above MDA in four samples taken at Site 17 (Columbia Water Works 25.0 mi. SE) at concentrations of 6.37E+2 pCi/L, 6.54E+2 pCi/L, 8.01 E+2 pCi/L, and 5. 71 E+2 pCi/L.. The highest indicator and control site-specific gross beta activity was measured at Site 28 (New Nuclear Deployment 2.6 mi. SSE) at a level of 4.30E+O pCi/I. 97.2% of indicator/control drinking water samples were collected.

There were no milk samples collected in 2015. Milk sampling is required to be performed at the three highest dose locations within 5 kilometers of the plant or at 5 to 8 kil.ometers of the plant, if doses are calculated to be greater than 1 mrem per year.

Presently there are no locations meeting this criteria for indicator dairies. The closest dairy is approximately 8 kilometers from the plant (see Table 4). Milk samples will be obtained from this dairy if gaseous releases from the plant exceed 5% of quarterly organ dose limits or radionuclides (attributed to the operation of VCSNS) are detected in broadleaf vegetation, grass or air samples at concentrations greater than required LLDs.

Gamma spectroscopy measurement of supplemental grass samples collected indicated 137Cs in 3 of 12 samples at Site 2 (transmission line 1.2 mi. SW) at concentrations of 2.18E+1 pCi/kg, 2.35E+1 pCi/kg, and 2.85E+1 pCi/kg. The maximum preoperational control activity was 3.40E+2 pCi/kg. 100% of indicator/control supplemental grass samples were collected.

l Gamma spectroscopy measurements of the broadleaf samples collected did not indicate the presence of activated corrosion or fission products above the respective MDAs. All of the required indicator/control broadleaf samples were collected.

Gamma spectroscopy measurements of all non-leafy (other vegetation) supplemental samples collected did not indicate the presence of activated corrosion or fission products above the respective MDA.

Gamma spectroscopy measurements of all fish samples collected did not indicate the presence of activated corrosion or fission products above the respective MDA. All of the required indicator/control fish samples were collected.

Gamma spectroscopy measurements of sediment samples indicated the detection of 137 Cs in 2 of 4 indicator samples. Site 21 (Parr Res. 2.7 mi. SSW) at concentrations of 2.27E+2 and 1.28E+2 pCi/kg were detected. 137 Cs was also detected in 2 of 2 control samples taken at Site 22 (Neal Shoals 26 mi. NNW) at concentrations of 5.99E+1 and 5.70E+1 pCi/kg. All required indicator/control sediment samples were collected.

CONCLUSION As in previous years of VCSNS operation, the presence of fission product activity attributed to residual fallout from atmospheric weapons testing and the Chernobyl accident were detected in environmental media including sediment and grass.

No detectable fission or activation product activity attributed to VCSNS operations was observed in environmental media with the exception of:

  • Tritium in four drinking water samples taken at site 17 (Columbia Water Works 25.0 mi. SE) and two supplemental samples taken at site 99 (Nuclear Operations Bldg). Concentrations were well below drinking water standards.
  • Co-60 and Cs-137 was detected in one supplemental soil sample taken at Site 25 (Fairfield Pumped Storage Penstocks 0.9 WNW).
  • Tritium in all four supplemental ground water samples taken at Site 123 (NPDES Well GW-16 0.34 mi. SSE).

The dose calculated for the maximum exposed individual will not result in observable effect on the ecosystem or general public. The results of the Radiological Environmental Monitoring Program, therefore, substantiate the continuing adequacy of source control at VCSNS and conformance of station operation to 10 CFR 50, Appendix I design objectives.

2. Sample site locations are based on 5-year average meteorological analysis.
3. Though generalized areas are noted for simplicity of sample site enumeration, airborne, water and sediment sampling is done at the same location, whereas biological sampling sites are generalized areas in order to reasonably assure availability of samples.
4. Milking animal and garden survey results will be analyzed annually. If the survey should indicate new activity the owners shall be contacted with regard to a contract for supplying sufficient samples. If contractual arrangements can be made, site(s) will be added for additional milk sampling up to a total of three Indicator locations.
5. Not to exceed 35 days.
6. Time composite samples are samples which are collected with equipment capable of collecting an aliquot at time intervals which are short relative to the compositing period.
7. At least once per 100 days.

Table 8 (cont) - Radiological Environmental Monitoring Program Summary for 2015 Footnotes

1. Includes indicator and control analyses. Site 8, Air Particulates and Air Radioiodines are included as indicators. Does not include other supplemental samples.
2. Values given are maximum MDA values for indicator locations calculated from the program data analyses. The maximum acceptable LLD values allowed from NRG guidelines are given in parentheses.
3. Mean and range are based on detectable measurements only. The fractions of detectable measurements (i.e., number of positive results/total number of measurements) at specific locations are indicated in parentheses.
4. Any confirmed measured level of radioactivity in any environmental medium that exceeds the reporting requirements of ODCM, Section 1.4.1.2.
5. Detection sensitivity is approximately 10 mrem/yr (1.0 µR/hr).
6. Elevated levels of 214 Pb and 214 Bi were observed in Jenkinsville drinking water samples.

The values are not reported here because they are naturally occurring (do not originate from VCSNS) and furnish no quantifiable information of interest.

7. Fish include 3 groups (Bass, Bream/Crappie, Catfish/Carp.)
8. Elevated levels of 214Pb and 214 Bi plus other 226 Ra daughter products and 228Ac plus other 232 Th daughter products were observed in all sediment samples. The values are not reported here because they are naturally occurring (do not originate from VCSNS) and furnish no quantifiable information of interest.

131

8. Drinking water resin prepared and counted for 1 as separate sample.

Table 9 (Cont.)- Radiological Environmental Monitoring Program Preoperational (Baseline) Summary Footnotes

1. Values given are MDA values calculated from the program data analyses with maximum acceptable LLD values allowed from NRG guidelines given in parenthe.ses.
2. Mean and range are based on detectable measurements only. The fractions of detectable measurements at specific locations are indicated in parentheses.
3. A non-routine measurement is any confirmed measured level of radioactivity in an environmental medium that exceeds the reporting requirements of VCSNS ODCM, Section 1.4.1.2.
4. The baseline values are high because of the fallout from the* Chinese bomb test in 1980.

The first set of data reflects the 1981 baseline. The second set of data reflects the 1982 baseline, essentially free of bomb test fallout. The 1982 data covers the period 1/1/82 -

10/22/82.

5. Detection sensitivity is approximately 5 mrem/yr (0.5 µR/hr) determined from the analyses of five years of preoperational data.
6.
  • No control location was specified for drinking water during the preoperational monitoring period.
7. Inconclusive data.
