SUMMARY

This Annual Radiological Environmental Operating Report describes the Oconee Nuclear Station Radiological Environmental Monitoring Program (REMP), and the program results for

the calendar year 2013.

0 Included are the identification of sampling locations, descriptions of environmental sampling and analysis procedures, comparisons of present environmental radioactivity levels and pre-operational environmental data, comparisons of doses calculated from environmental 0measurements and effluent data, analysis of trends in environmental radiological data as potentially affected by station operations, and a summary of environmental radiological sampling results. Quality assurance practices and program changes are also discussed.

Sampling activities were conducted as prescribed by Selected Licensee Commitments

(SLC's).

Required analyses were performed and detection capabilities were met for all collected samples as required by SLC's. Nine-hundred ninety-three samples were analyzed comprising 1,058 test results in order to compile data for the 2013 report. Based on the annual land use census, the current number of sampling sites for Oconee Nuclear Station is

sufficient.

0 Concentrations observed in the environment in 2013 for station related radionuclides were within the ranges of concentrations observed in the past. Inspection of data showed that radioactivity concentrations in drinking water, surface water, shoreline sediment, fish, and

broadleaf vegetation are higher than the activities reported for samples collected at control

locations.

All positively identified measurements attributable to station operation were within limits as specified in SLC's.

Additionally, environmental radiological monitoring data is consistent with effluents

introduced into the environment by plant operations. The total body dose estimated to the maximum exposed member of the public as calculated by environmental sampling data, excluding TLD results, was 1.62E-01 mrem for 2013.

Background radiation dose in the

United States is approximately 620 mrem per year (approximately half from naturally occurring sources such as radon and half from man-made sources such as medical processes)

(reference 6.15).

It is therefore concluded that station operations has had no significant radiological impact on the health and safety of the public or the environment.

2.0 INTRODUCTION

2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS Oconee Nuclear Station (ONS) is located in Oconee County, South Carolina, approximately 8 0miles northeast of Seneca, South Carolina, on the shore of Lake Keowee. This lake was formed

by damming the Keowee and Little Rivers in that location. Immediately to the south is the U.S.

Government Hartwell Project. The Keowee Hydroelectric Plant near the station joins Lake Keowee and the upper reaches of Lake Hartwell. To the north, the Jocassee Hydroelectric Plant joins Lake Jocassee and Lake Keowee. Jocassee is a pumped storage plant.

ONS consists of three pressurized water reactors. Each unit has an output of 846 megawatts

net.

Unit 1 license for operation was issued 2/6/1973. Unit 2 license for operation was issued 10/6/1973.

Unit 3 license for operation was issued 7/19/1974.

An independent spent fuel

storage installation is also located at the site.

Figures 2.1-1 and 2.1-2 are maps depicting the Thermoluminescent Dosimeter (TLD) monitoring locations and the sampling locations. The location numbers shown on these maps 0correspond to those listed in Tables 2.1-A and 2.1-B.

Figure 2.1-1 comprises all sample

locations within a one mile radius of ONS. Figure 2.1-2 comprises all sample locations within a

ten mile radius of ONS.

2.2 SCOPE AND REQUIREMENTS OF THE REMP An environmental monitoring program has been in effect at Oconee Nuclear Station since 1969,

four years prior to operation of Unit 1 in 1973. The preoperational program provides data on the existing environmental radioactivity levels for the site and vicinity which may be used to 0determine whether increases in environmental levels are attributable to the station. The Soperational program provides surveillance and backup support of detailed effluent monitoring which is necessary to evaluate the significance, if any, of the contributions to the existing environmental radioactivity levels that result from station operation.

SThis monitoring program is based on NRC guidance as reflected in the Selected Licensee 0Commitments Manual, with regard to sample media, sampling locations, sampling frequency, and analytical sensitivity requirements. Indicator and control locations were established for comparison purposes to distinguish radioactivity of station origin from natural or other "man-made" environmental radioactivity.

The environmental monitoring program also verifies 5projected and anticipated radionuclide concentrations in the environment and related exposures from releases of radionuclides from Oconee Nuclear Station. This program satisfies the requirements of Section IV.B.2 of Appendix I to 10CFR50 and 10CFR72.44(d)(2) and provides surveillance of all appropriate critical exposure pathways to man and protects vital interests of Sthe company, public, and state and federal agencies concerned with the environment. Reporting

levels for radioactivity found in environmental samples are listed in Table 2.2-A. Table 2.2-B

lists the REMP analysis and frequency schedule.

The Annual Land Use Census, required by Selected Licensee Commitments, is performed to ensure that changes in the use of areas at or beyond the site boundary are identified and that O

modifications to the Radiological Environmental Monitoring Program are made if required by changes in land use. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR50. Results are shown in Table 3.9.

Participation in an interlaboratory comparison program as required by Selected Licensee 0

Commitments provides for independent checks on the precision and accuracy of measurements of radioactive material in REMP sample matrices. Such checks are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR50. A summary of the 0

results obtained as part of this comparison program are in Section 5 of this annual report.

2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY 2.3.1 ESTIMATION OF THE MEAN VALUE 00 There was one (1) basic statistical calculation performed on the raw data resulting from 0

the environmental sample analysis program. The calculation involved the determination S

of the mean value for the indicator and the control samples for each sample medium.

5 The mean is a widely used statistic. This value was used in the reduction of the data generated by the sampling and analysis of the various media in the Radiological Environmental Monitoring Program. "Net activity (or concentration)" is the activity (or 0

concentration) determined to be present in the sample.

No "Minimum Detectable 5

Activity", "Lower Limit of Detection", "Less Than Level", or negative activities or concentrations are included in the calculation of the mean. The following equation was used to estimate the mean (reference 6.8):

N*

Yxi0 N

Where:

o x = estimate of the mean, 0

i = individual sample, 0

N = total number of samples with a net activity (or concentration),

Xi = net activity (or concentration) for sample i.

S 2.3.2 LOWER LEVEL OF DETECTION AND MINIMUM

DETECTABLE ACTIVITY

The Lower Level of Detection (LLD) and Minimum Detectable Activity (MDA) are

used throughout the Environmental Monitoring Program.

LLD - The LLD, as defined in the Selected Licensee Commitments Manual is the 0smallest concentration of radioactive material in a sample that will yield a net count,

above the system background, that will be detected with 95% probability with only 5%

probability of falsely concluding that a blank observation represents a "real" signal. The LLD is an a priori lower limit of detection. The actual LLD is dependent upon the standard deviation of the background counting rate, the counting efficiency, the sample size (mass or volume), the radiochemical yield, and the radioactive decay of the sample between sample collection and counting. The "required" LLD's for each sample medium and selected radionuclides are given in the Selected Licensee Commitments and are listed in Table 2.2-C.

IMDA

- The MDA is the net counting rate (sample after subtraction of background) that must be surpassed before a sample is considered to contain a scientifically measurable amount of a radioactive material exceeding background amounts.

The MDA is 0calculated using a sample background and may be thought of as an "actual" LLD for a 0particular sample measurement.

2.3.3 TREND IDENTIFICATION 9One of the purposes of an environmental monitoring program is to determine if there is a 5buildup of radionuclides in the environment due to the operation of the nuclear station.

Visual inspection of tabular or graphical presentations of data (including preoperational) is used to determine if a trend exists.

A decrease in a particular radionuclide's concentration in an environmental medium does not indicate that reactor operations are Sremoving radioactivity from the environment but that reactor operations are not adding that radionuclide to the environment in quantities exceeding the preoperational level and that the normal removal processes (radioactive decay, deposition, resuspension, etc.) are influencing the concentration.

Substantial increases or decreases in the amount of a particular radionuclide's release from the nuclear plant will greatly affect the resulting environmental levels; therefore, a knowledge of the release of a radionuclide from the nuclear plant is necessary to 0completely interpret the trends, or lack of trends, determined from the environmental data.

Some factors that may affect environmental levels of radionuclides include prevailing weather conditions (periods of drought, solar cycles or heavier than normal precipitation), construction in or around either the nuclear plant or the sampling location, Sand addition or deletion of other sources of radioactive materials (such as the Chernobyl

accident).

Some of these factors may be obvious while others are sometimes unknown.

5Therefore, how trends are identified will include some judgment by plant personnel.

3.0 INTERPRETATION OF RESULTS 0

Review of 2013 REMP analysis results was performed to identify changes in environmental levels as a result of station operations. The review is summarized in this section. Data from 2013 was compared to preoperational and historical data. Sample data for some media is not 0directly comparable to preoperational and earlier operational sample results because of either

significant changes in the analysis methods or changes in the reporting of the results.

0 Evaluation for significant trends was performed for the radionuclides that have required LLDs 0listed in Selected Licensee Commitment 16.11.6. These radionuclides are collectively referred 0to as "Selected Licensee Commitments radionuclides" and include H-3, Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-140, and La-140. Drinking water gross beta results are routinely trended. Trending of air particulate gross beta results was initiated in 1996 when the analysis was resumed. Trending is also performed for other radionuclides that are

detected and could have been the result of station effluents. Only Selected Licensee Commitment

radionuclides were detected in 2013.

Trending was performed by comparing annual mean concentrations of any effluent related 0detected radionuclide to historical results. Factors evaluated include the frequency of detection

and the concentration in terms of the percent of the radionuclide's SLC reporting level (Table

2.2-A).

All maximum percent of reporting level values were well below the 100% action level.

The highest value reached during 2013 due to ONS operation was 2.1% for H-3 in a drinking water sample collected at location 066.

0 0Changes in sample location, analytical technique, and presentation of results must be considered

when reviewing for trends. Calculation of the annual mean concentrations has been performed differently over the history of the REMP. During 1979-1986, all net results (sample minus 0background), positive and negative, were included in the calculation of the mean. Only positive 0net activity results were used to calculate the mean for the other years. A change in gamma spectroscopy analysis systems in 1987 ended a period when many measurements yielded detectable low-level activity for both indicator and control location samples. It is thought that the method the previous system used to estimate net activity may have been vulnerable to false-

positive results.

0 0Data presented in Sections 3.1 - 3.8 support the conclusion that there were no significant increases in radionuclides in the environment around ONS due to station operations in 2013.

3.1 AIRBORNE RADIOIODINE AND PARTICULATES In 2013, 312 radioiodine and particulate samples were analyzed, 260 from five indicator locations and 52 from the control location. Particulate samples were analyzed weekly for gross beta. A quarterly gamma analysis was performed on the quarterly filter composite (by location).

Radioiodine samples received a weekly gamma analysis.

There was no detectable 1-131 in air samples in 2013. Table 3.1-A gives the highest indicator location annual mean and control location annual mean for 1-131 since the preoperational period.

The table shows similar historical concentrations for both the indicator and control locations and the activities decreasing from early in the operational history of the plant. No 1-131 activity due to ONS plant operations has been detected since 1994.

There were no detectable gamma emitting radionuclides detected in air particulate samples in 2013 due to ONS plant operations. No gamma emitting particulates due to ONS plant operations have been detected in indicator location samples since the change in gamma spectroscopy analysis systems in 1987.

Beta analysis of particulate filters was initiated in March of 1996 and became required by Selected Licensee Commitments in 1998. Gross beta analysis was performed on particulate filters during the preoperational and early operational history of the plant but had not been required since 1984. Figure 3.1 summarizes gross beta results for the indicator location with the highest annual mean and the control location samples. Both the indicator and control location results are similar in concentration and are near the lower range of preoperational gross beta results.

K-40 and Be-7 are the naturally occurring radionuclides that were observed in air samples.

3.2 DRINKING WATER Gross beta analysis and gamma spectroscopy were performed on 39 monthly drinking water samples. These samples were composited to form 12 quarterly period samples for Tritium analysis. Two indicator locations and a control location were sampled; however, only one of the indicator locations is downstream of the effluent release point.

Table 3.2 lists the highest indicator location annual mean and control location annual mean for gross beta results since the preoperational period.

The indicator location had an average concentration of 1.57 pCi/liter in 2013, and the control location had a concentration of 1.11 pCi/liter. The 2012 indicator mean was 1.40 pCi/liter. The table shows that 2013 gross beta levels in drinking water are lower than preoperational concentrations. The dose for consumption of water was less than one mrem per year, historically and for 2013; therefore low-level iodine analysis is not required.

Tritium was detected in three of the twelve composite samples during 2013. The 2013 mean indicator location 066 concentration was 325 pCi/liter, which is 1.63% of the reporting level.

Table 3.2 and Figure 3.2 show the highest indicator and control location annual means for Tritium since analysis was initiated early in the operational period. Tritium concentrations have decreased at both the indicator and control locations. The closure of the Clemson water plant in 1989 is one reason for the decrease shown in the table and graph. The Clemson site was typically the high mean location when the plant was in operation.

There were no gamma emitting radionuclides identified in drinking water samples in 2013.

Gamma spectroscopy analysis has not detected any activity in the water supplies since 1988.

K-40 is the naturally occurring radionuclide that was observed in drinking water samples.

3.3 SURFACE WATER Gamma spectroscopy was performed on 26 monthly surface water samples. These samples were composited to form eight quarterly samples for Tritium analysis. One indicator and one control location were sampled. The indicator location is near the liquid effluent release point.

Tritium was detected in the four indicator location samples. The 2013 average concentration was 3,683 pCi/liter. The individual samples ranged from 1,290 to 7,890 pCi/liter. The 2012 mean concentration was 5,760 pCi/liter. Tritium was not detected in any control surface water samples.

Figure 3.3 shows the indicator and control annual means for Tritium since the preoperational period. Table 3.3 lists the indicator annual means.

Gamma spectroscopy analysis did not detect any station related activity during 2013. No gamma emitting radionuclides attributable to station operation have been detected in surface water samples since 1999. Table 3.3 summarizes the indicator annual means of radionuclides detected since the change in the gamma spectroscopy analysis system in 1987. Visual inspection of the gamma spectroscopy tabular data covering the early operational period through 2013 did not reveal any increasing trends.

K-40 and Be-7 are the naturally occurring radionuclide observed in surface water samples in 2013.

3.4 MILK Gamma spectroscopy and low level iodine analysis was performed on 26 milk samples collected in 2013. One control location was sampled. No indicator dairies were identified by the 2013 land use census.

There were no gamma emitting radionuclides due to ONS plant operations identified in milk samples in 2013. Cs-137 is the only radionuclide, other than naturally occurring, reported in milk samples since 1988 (excluding Fukushima Daiichi). Cs-137 in milk is not unusual. It is a constituent of nuclear weapons test fallout and nuclear plant accidents and has been observed periodically in samples from indicator and control locations since the preoperational period.

Table 3.4 lists the highest indicator location annual mean and control location annual mean for Cs-137 since the preoperational period.

The table shows similar concentrations for both indicator and control locations.

K-40 is a naturally occurring radionuclide observed in milk samples in 2013.

3.5 BROADLEAF VEGETATION Gamma spectroscopy was performed on 48 broadleaf vegetation samples during 2013. Three indicator locations and one control location were sampled.

Cs-137 was reported in one indicator sample at a concentration of 25.7 pCi/kg (1.29% of reporting level). Cs-137 was not detected in any of the control samples in 2013.

Cs-137 is the only radionuclide, other than naturally occurring, reported in vegetation samples since the change in gamma spectroscopy analysis systems in 1987. Table 3.5 shows historical concentrations of Cs-137.

It is not unusual for Cs-137 to be present in vegetation. It is a constituent of nuclear weapons test fallout and nuclear plant accidents and has been observed in samples from indicator and control locations since the preoperational period. Table 3.5 lists the highest indicator location annual mean and control location annual mean for Cs-137 since early in the station's operational history. Visual inspection of the tabular data did not reveal any increasing trends.

3.6 FISH In 2013, gamma spectroscopy was performed on 13 fish samples. Two downstream indicator and one control location were sampled. Cs-137 was identified in eight of the nine indicator location samples. Cs-137 was detected in three of the four control location samples at a mean concentration of 16.0 pCi/kg. The highest average indicator concentration for Cs-137 was 24.4 pCi/kg (1.22% of reporting level).

Figures 3.6-1 and 3.6-2 are graphs displaying the annual means for Cs-137 and Cs-134.

Historically, both are contributors to the calculated dose from liquid effluents from ingestion of fish. Radioactivity concentrations in downstream fish samples are higher than those reported in preoperational fish samples, however, concentrations in fish have decreased over time with decreases in radioactive material releases from the plant.

One factor affecting the trend analysis is a change in sampling locations. In 1984, a second downstream fish location was added. Location 063 is closer to the liquid effluent discharge point and has been the highest mean indicator since it was added.

Table 3.6 lists the highest indicator location annual means since the preoperational period for radionuclides detected in 2013. Also included in the table are radionuclides that have been identified in this media since the change in analysis systems in 1987. Comparison of data to previous years does not indicate any increases in concentrations.

K-40 was observed in fish samples in 2013.

0 3.7 SHORELINE SEDIMENT Gamma spectroscopy was performed on six sediment samples. Two downstream indicator locations and one control location were sampled. Four samples were taken from indicator locations and two from the control location.

Cs-137 was identified in one of the four indicator location samples.

Cs-137 was not identified in the control location samples.

The highest 2013 individual sample Cs-137 concentration was 43.7 pCi/kg. The highest 2012 individual sample Cs-137 concentration was 80.6 pCi/kg. Table 3.7 lists the highest indicator location annual means since shoreline sediment was initiated in 1984. Included in the table are radionuclides that have been identified in this media since the change in analysis systems in 1987.

Visual inspection of the tabular data did not reveal any trends. Figure 3.7-1 is a graph of the Cs-137 annual means. Figure 3.7-2 is a graph of the Co-60 annual means. Historically, both are contributors to the calculated dose from liquid effluents from shoreline sediment. No trends are apparent.

K-40 and Be-7 are naturally occurring radionuclides observed in shoreline sediment samples in 2013.

3.8 DIRECT GAMMA RADIATION 3.8.1 ENVIRONMENTAL TLD 0

In 2013, 167 Thermoluminescent Dosimeters (TLD) were analyzed, 159 at indicator locations, 8 at the two control locations. TLDs are collected and analyzed quarterly.

A transit background for environmental TLDs is determined based on ANSI N545.

The highest annual mean exposure for an indicator location was 110.4 milliroentgen.

This TLD is located at indicator location 040, 4.74 miles from the station. The annual mean exposure for the control locations was 110.2 milliroentgen.

Figure 3.8 and Table 3.8 show TLD inner ring (site boundary), outer ring (4-5 miles),

and control location annual averages in milliroentgen per year. Data is provided from 0

1984 when TLD locations were added and arranged in an inner ring and outer ring configuration. Preoperational data is also provided in the table. As shown in the graph, inner and outer ring averages historically compare closely, with control data somewhat higher. Inner and outer ring averages comprise a number of data points with control averages representing only two locations. The control locations have historically been higher than indicator locations. This is most likely an artifact of the underlying geologic structures at the control locations. The control locations are 9.39 miles WSW and 9.33 miles SE, well beyond the influence of the plant.

0 The calculated total body dose (from gaseous effluents) for 2013 was 1.14E-1 mrem, which is 0. 14% of the average inner ring TLD values. Therefore, it can be concluded that discharges from the plant had very little impact upon the measured TLD values.

0 A TLD intercomparison program is conducted as part of the quality assurance program. Results of this program are included in section 5.10.

3.8.2 ISFSI The Oconee Independent Spent Fuel Storage Installation (ISFSI) is a fenced, secured area constructed to provide dry storage for spent nuclear fuel.

The principal components of the ISFSI are concrete horizontal storage modules that hold stainless steel dry storage canisters containing irradiated fuel assemblies.

Oconee began storage of spent fuel at the ISFSI in 1990.

The ISFSI is located in the southwest end of the plant, approximately 400 meters from Unit 2 reactor building. The radiological environmental monitoring program for Oconee also serves as the operational program for the ISFSI. No liquid or airborne effluents are anticipated from the passive storage provided by the ISFSI. Therefore any dose to offsite points would be from direct and scattered gamma radiation.

Several environmental TLD locations are presently located at the Oconee site boundary fence near the ISFSI. The closest of these is 0.3 miles from the ISFSI, well within the 1-mile exclusion boundary. In addition, dose rates at the ISFSI restricted area fence are monitored with TLDs and used in monitoring occupational exposure controls.

0 4.0 EVALUATION OF DOSE 0

0 4.1 DOSE FROM ENVIRONMENTAL MEASUREMENTS Annual doses to maximum exposed individuals were estimated based on measured

concentrations of radionuclides in 2013 ONS REMP samples.

The primary purpose of 0estimating doses based on sample results is to allow comparison to effluent program dose estimates. Doses based on sample results were conservatively calculated in a manner as equivalent as possible to effluent-based dose estimates.

Doses based on REMP sample results were calculated using the methodology and data presented in NRC Regulatory Guide 1.109. Measured radionuclide concentrations, averaged over the entire year for a specific radionuclide, indicator location, and sample type, were used to calculate REMP-based doses, after subtracting the applicable average background 0concentration (as measured at the corresponding control location). Regulatory Guide 1.109 0consumption rates for the maximum exposed individual were used in the calculations. A dose

factor of zero was assumed when the guide listed "NO DATA" as the dose factor for a given radionuclide and organ.

0Maximum dose estimates calculated using drinking water, fish, shoreline sediment, and

broadleaf vegetation results are reported in Table 4.1-A. The individual critical population

and pathway dose calculations are contained in Table 4.1-B.

No radionuclides were detected in milk, airborne radioiodine or airborne particulate samples.

Naturally occurring K-40 and Be-7 were detected in some samples but were not included in any REMP-based dose estimates.

Dose estimates were not calculated for surface water samples because surface water is not considered a potable drinking water source although 0surface water tritium concentrations are used in calculating doses from fish. REMP TLD 0exposure results are discussed in Section 3.8.

0 The maximum environmental organ dose estimate for any single sample type (excluding TLD results) collected during 2013 was 2.19E-l mrem to the child bone from consuming broadleaf

vegetation.

0 4.2 ESTIMATED DOSE FROM RELEASES Throughout the year, dose estimates were calculated based on actual 2013 liquid and gaseous 0effluent release data. Effluent-based dose estimates were calculated using the RETDAS

computer program which employs methodology and data presented in NRC Regulatory Guide

1.109.

These doses are shown in Table 4.1-A along with the corresponding REMP-based dose estimates.

Summaries of RETDAS dose calculations are reported in the Annual Radioactive Effluent Release Report (reference 6.6).

I The effluent-based liquid release doses are summations of the dose contributions of the drinking water, fish and shoreline pathways. For iodine, particulate, and tritium exposure the effluent-based gaseous release doses are summations of the dose contributors from ground/plane, milk, inhalation and vegetation pathways.

4.3 COMPARISON OF DOSES II The liquid environmental and release data doses given in Table 4.1-A agree reasonably well.

The similarity of the doses indicate that the radioactivity levels in the environment do not differ significantly from those expected based on effluent measurements and modeling of the 6

environmental exposure pathways.

There are some differences in how effluent and environmental doses are calculated that affect the comparison. Doses calculated from environmental data are conservative because they are based on a mean that includes only samples with a net positive activity versus a mean that includes all sample results (i.e. zero results are not included in the mean). Also, airborne tritium is not measured in environmental samples but is used to calculate effluent doses.

Additionally, in 2010 Oconee began reporting estimated dose from effluent Carbon 14 (C-14).

This change came about with the issuing of Regulatory Guide 1.21, Revision 2, Measuring, Evaluating and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste.

A description of this change is found in the 2010 Annual Radiological Effluent Release Report. C-14 is not measured in the environment and therefore, environmental and effluent doses from C-14 cannot be compared directly.

In calculations based on liquid release effluent pathways, fish and drinking water were the 0

predominant dose pathways based on environmental and effluent samples. The maximum 9

total organ dose based on 2013 environmental sample results was 5.64E-2 mrem to the child liver. The maximum total organ dose of 3.OOE-1 mrem for liquid effluent-based estimates was to the adult GI-LLI.

S In calculations based on gaseous release pathways, vegetation was the predominant dose pathway for effluent samples.

The gaseous effluent dose is due to C-14 and tritium in broadleaf vegetation.

The maximum total organ dose for gaseous effluent estimates was 3.36E-1 mrem to the child bone. Vegetation was the only gaseous release pathway media that contained detectable activity.

The maximum total organ dose for gaseous environmental estimates was 2.19E-1 mrem to the child bone.

The doses calculated do not exceed 40CFR190 or 10CFR50 dose commitment limits for members of the public. Doses to members of the public attributable to the operation of ONS are being maintained well within regulatory limits.

ENVIRONMENTAL SAMPLING AND 0

ANALYSIS PROCEDURES 00 Adherence to established procedures for sampling and analysis of all environmental media at Oconee Nuclear Station is required to ensure compliance with Station Selected Licensee Commitments.

Analytical procedures were employed to ensure that Selected Licensee Commitments detection capabilities were achieved.

0 Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, and Fisheries and Aquatic Ecology.

Section IV of this appendix describes the environmental sampling frequencies and analysis procedures by media type.

I.

CHANGE OF SAMPLING PROCEDURES No changes were made to the sampling procedures during 2013.

II.

DESCRIPTION OF ANALYSIS PROCEDURES Gamma spectroscopy analyses are performed using high purity germanium gamma detectors and Canberra analytical software.

Designated sample volumes are transferred to appropriate counting geometries and analyzed by gamma spectroscopy.

Perishable samples such as fish and broadleaf vegetation are ground to achieve a homogeneous mixture. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.) then transferred to appropriate counting geometry.

Low-level iodine analyses are performed by passing a designated sample aliquot through a pre-weighed amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk). The resin is then dried, mixed thoroughly, and a net resin weight determined before being transferred to appropriate counting geometry and analyzed by gamma spectroscopy.

Tritium analyses are performed quarterly by using low-level environmental liquid scintillation analysis technique on a Packard 2550 liquid scintillation system or Perkin-Elmer 2900TR liquid scintillation system. Tritium samples are distilled and batch processed with a laboratory fortified blank, matrix spike, matrix spike duplicate, and blank to verify instrument performance and sample preparation technique are acceptable.

0 Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate and analyzing by Tennelec XLB Series 5 gas-flow proportional counters.

CHANGE OF ANALYSIS PROCEDURES 0

Quarterly gamma spectroscopy analysis of airborne particulate filter composite (by

location) was implemented during 2013; elective weekly gamma spectroscopy of the airborne particulate individual filter was discontinued.

IV.

SAMPLING AND ANALYSIS PROCEDURES 0

A.1 AIRBORNE PARTICULATE AND RADIOIODINE 0Airborne particulate and radioiodine samples at each of six locations were composited continuously by means of continuous air samplers. Air particulates

were collected on a particulate filter and radioiodines were collected in a charcoal cartridge positioned behind the filter in the sampler. The samplers are designed to operate at a constant flow rate (in order to compensate for any filter

loading) and are set to sample approximately 2 cubic feet per minute. Filters and cartridges were collected weekly.

A separate weekly gamma analysis was performed on each charcoal cartridge.

A weekly gross beta analysis was performed on each filter. A quarterly gamma analysis was performed on the 0quarterly filter composite (by location). The continuous composite samples

were collected from the locations listed below.

A.8 DIRECT GAMMA RADIATION (TLD)

Thermoluminescent dosimeters (TLD) were collected quarterly at forty-two Slocations.

A gamma exposure rate was determined for each TLD. The TLDs 5were placed as indicated below.

0An inner ring of 17 TLDs, one in each meteorological sector in the

general area of the site boundary.

An outer ring of 16 TLDs, one in each meteorological sector in the 6 to 8 kilometer range.

The remaining TLDs were placed in special interest areas such as population centers, residential areas, schools, and control locations.

TLD Locations are listed in Table 2.1-B.

S A.9 ANNUAL LAND USE CENSUS

An annual Land Use Census was conducted to identify within a distance of 8

kilometers (5.0 miles) from the station, the following locations in each of the sixteen meteorological sectors:

The Nearest Residence S*

The Nearest Milk-giving Animal (cow, goat, etc.) where milk is used for

human consumption The census was conducted during the growing season 5/20/2013. Results are shown in Table 3.9. No changes were made to the sampling procedures during

2013 as a result of the 2013 census.

Footnotes to Appendix B

1.

The Lower Limit of Detection (LLD) is the smallest concentration of radioactive material in a sample that will yield a net count above system background which will be detected with 95 percent probability and with only 5 percent probability of falsely concluding that a blank observation represents a "real" signal. Due to counting statistics and varying volumes, occasionally lower LLDs are achieved. Refer to Section 2.3.2 for an explanation of how LLD values were derived.

2.

Mean and range are based on detectable measurements only.

3.

The fractions of all samples with detectable activities at specific locations are indicated in parentheses.

4.

Missing samples or surveillances are discussed in Appendix C or Appendix D.

5.

TLD exposure is reported in milliroentgen (mR) per standard quarter (91 days).
