SUMMARY
This Annual Radiological Environmental Operating Report describes the Catawba -
Nuclear Station Radiological Environmental
- Monitoring Program (REMP), and the program results for the calendar year 2009.
Included are the identification of sampling 0locations, descriptions of environmental sampling and analysis procedures, comparisons of present environmental radioactivity levels and pre-operational environmental data, comparisons of doses calculated from environmental measurements 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, sampling deviations, unavailable samples, and program changes are also discussed.
SSampling activities were conducted as prescribed by Selected Licensee Commitments
- (SLCs). Required analyses were performed and detection capabilities were met for all
- collected samples as required by SLCs. Eight-hundred eighty-eight samples were analyzed comprising 1,197 test results in order to compile data for the 2009 report. Based on the annual land use census, the current number of sampling sites for Catawba Nuclear Station is
- sufficient.
S Concentrations observed in the environment in 2009 for station related radionuclides were generally within the ranges of concentrations observed in the past. Inspection of data showed Sthat radioactivity concentrations in surface water, drinking water, shoreline sediment, and fish
- are higher than the activities reported for samples collected prior to the operation of the station. Measured concentrations were not higher than expected, and all positively identified measurements were within limits as specified in SLCs.
- Additionally, environmental radiological monitoring data is consistent with effluents
- introduced into the environment by plant operations. The total body dose estimated to the 5maximum exposed member of the public as calculated by environmental sampling data,
- excluding TLD results, was 2.01E-01 mrem for 2009. It is therefore concluded that station operations has had no significant radiological impact on the health and safety of the public or S the environment.

2.0 INTRODUCTION
S
- 2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS 0
Duke Energy Corporation's Catawba Nuclear Station is a two-unit facility located on the shore of Lake Wylie in York County, South Carolina. Each of the two essentially identical units 0employs a pressurized water reactor nuclear steam supply system furnished by Westinghouse 0Electric Corporation. Each generating unit is designed to produce a net electrical output of
- approximately 1145 MWe. Units 1 and 2 achieved initial criticality on January 7, 1985, and
- May 8, 1986, respectively.
SCondenser cooling is accomplished utilizing a closed system incorporating cooling towers,
- instead of using lake water directly. Liquid effluents are released into Lake Wylie via the station discharge canal and are not accompanied by the large additional dilution water flow associated with "once-through" condenser cooling. This design results in greater radionuclide concentrations in the discharge canal given comparable liquid effluent source terms.

The location numbers shown on these maps correspond 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 CNS. Figure 2.1-2 comprises all sample locations within
- a 10 mile radius of CNS.

- 2.2 SCOPE AND REQUIREMENTS OF THE REMP 0
5An environmental monitoring program has been in effect at Catawba Nuclear Station since
- 1981, four years prior to operation of Unit 1 in 1985. 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 0operational 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.
0This monitoring program is based on NRC guidance as reflected in the Selected Licensee 5Commitments 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 0projected and anticipated radionuclide concentrations in the environment and related exposures 5from releases of radionuclides from Catawba Nuclear Station. This program satisfies the
- requirements of Section IV.B.2 of Appendix I to 10CFR50 and provides surveillance of all appropriate critical exposure pathways to man and protects vital interests of the company, 0

public and state and federal agencies concerned with the environment. Reporting levels for activity found in environmental samples are listed in Table 2.2-A.
Table 2.2-B lists the REMP analysis and frequency schedule.
0 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 modifications to the REMP are made if required by changes in land use. This census satisfies 0 the requirements of Section IV.B.3 of Appendix I to 10CFR50. Results are shown in Table 0 3.11.
Participation in an interlaboratory comparison program as required by Selected Licensee Commitments provides for independent checks on the precision and accuracy of measurements 0 of radioactive material in REMP sample matrices. Such checks are performed as part of the S quality assurance program for environmental monitoring in order to demonstrate that the results 0 are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR50. A summary of the results obtained as part of this comparison program are in Section 5 of this annual report.
2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY S
2.3.1 ESTIMATION OF THE MEAN VALUE 0 0
There was one (1) basic statistical calculation performed on the raw data resulting from 5 the environmental sample analysis program. The calculation involved the determination of the mean value for the indicator and the control samples for each sample medium.
The mean is a widely used statistic. This value was used in the reduction of the data 0 generated by the sampling and analysis of the various media in the Radiological 0 Environmental Monitoring Program. "Net activity (or concentration)" is the activity (or 5 concentration) determined to be present in the sample. No "Minimum Detectable 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 0 used to estimate the mean (reference 6.8): 0 Lx, N
O X -- iN O Where: O O
x = estimate of the mean, O i = individual sample, O N = total number of samples with a net activity (or concentration),
Xi = net activity (or concentration) for sample i. 0 S

- 2.3.2 LOWER LEVEL OF DETECTION AND MINIMUM DETECTABLE ACTIVITY
- used throughout the REMP.
LLD - The LLD, as defined in the Selected Licensee Commitments Manual is the smallest 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 Sbetween sample collection and counting. The "required" LLD's for each sample 0medium and selected radionuclides are given in the Selected Licensee Commitments
- and are listed in Table 2.2-C.
MDA - The MDA is the net counting rate (sample after subtraction of background) that 0must be surpassed before a sample is considered to contain a scientifically measurable 0amount of a radioactive material exceeding background amounts. The MDA is calculated using a sample background and may be thought of as an "actual" LLD for a particular sample measurement.
- 2.3.3 TREND IDENTIFICATION S
One of the purposes of an environmental monitoring program is to determine if there is a buildup 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 0concentration in an environmental medium does not indicate that reactor operations are removing 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 0influencing the concentration.
0
- 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 5data. 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, and addition or deletion of other sources of radioactive materials (such as the SChernobyl accident). Some of these factors may be obvious while others are sometimes
- unknown. Therefore, how trends are identified will include some judgment by plant personnel.

- 3.0 INTERPRETATION OF RESULTS
- Review of all 2009 REMP analysis results was performed to identify changes in environmental levels as a result of station operations. The following section depicts and explains the review of these results. Sample data for 2009 was compared to preoperational 0and historical data. Over the years of operation, analysis and collection changes have taken place that do not allow direct comparisons for some data collected from 1984 (preoperational) through 2009. Summary tables containing 2009 information required by Technical
- Specification Administrative Control 5.6.2 are located in Appendix B.
Evaluation for significant trends was performed for radionuclides that are listed as required
- within Selected Licensee Commitments 16.11-13. The radionuclides 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. Gross beta analysis results were trended for drinking water and gross beta trending
- for air particulates was initiated in 1996. Other radionuclides detected that are the result of 0plant operation, but not required for reporting, are trended.
0 A comparison of annual mean concentrations of effluent-based detected radionuclides to historical results provided trending bases. Frequency of detection and concentrations related
- to SLC reporting levels (Table 2.2-A) were used as criteria for trending conclusions. All 2009 0maximum percentages of reporting levels were well below the 100% action level. The highest
- value noted during 2009 was 3.53% for Co-60 in surface water.
Selected Licensee Commitment section 16.11-13 addresses actions to be taken if radionuclides other than those required are detected in samples collected. The occurrences of
- P these radionuclides are the result of CNS liquid effluents which contained the radionuclides.
0
- During 1979-1986, all net activity results (sample minus background), both positive and negative were included in calculation of sample mean. A change in the EnRad gamma 0 spectroscopy system on September 1, 1987, decreased the number of measurements yielding
- detectable low-level activity for indicator and control location samples. It was thought that the method used by the previous system was vulnerable to false-positive results.
All 2009 sample analysis results were reviewed to detect and identify any significant trends.
- Tables and graphs are used throughout this section to display data from effluent-based
- radionuclides identified since the system change in late 1987. All negative concentration values were replaced with zero for calculation purposes. Any zero concentrations used in tables or graphs represent activity measurements less than detectable levels.
Review of all 2009 data presented in this section supports the conclusion that there were no 0significant changes in environmental sample radionuclide concentrations of samples collected and analyzed from CNS site and surrounding areas that were attributable to plant operations.

3.1 AIRBORNE RADIOIODINE AND PARTICULATES 0
In 2009, 257 radioiodine and particulate samples were analyzed, 206 from four indicator 0 locations and 51 at the control location. Particulate samples were analyzed weekly for gamma and gross beta. Radioiodine samples received a weekly gamma analysis.
S Figure 3.1 shows individual sample gross beta results for the indicator location with highest annual mean and the control location samples during 2009. The two sample locations' results S are similar in concentration and have varied negligibly since preoperational periods.
There were no detectable gamma emitters identified for particulate filters analyzed during 2009. Table 3.1-A shows the highest indicator 0
annual mean and control location annual mean for gross beta in air particulate.
0 There was no detectable 1-131 in air radioiodine samples analyzed in 2009. Table 3.1-B shows the highest indicator annual mean S and control location annual mean for 1-131 since 1984 (preoperational period). 0 K-40 and Be-7 that occur naturally were routinely detected in charcoal cartridges collected S
during the year. Cs-137 detection on the charcoal cartridge was determined in 1990 to be an 0 active constituent of the charcoal. A similar study was performed in 2001 again yielding 0 this conclusion. Therefore, any Cs-137 activities were not used in any dose calculations in 0 Section 4.0 of this report.

- 3.2 DRINKING WATER Gross beta and gamma spectroscopy were performed on 26 drinking water samples. The samples were composited to create 8 quarterly samples that were analyzed for tritium. One 0indicator location was sampled, along with one control location.
N hNo gamma emitting radionuclides were identified in 2009 drinking water samples. There have been no gamma emitting radionuclides identified in drinking water samples since 1988.
Table 3.2 shows highest annual mean gross beta concentrations for the indicator location and control location since preoperation. The indicator location (downstream of the plant effluent
- release point) average concentration was 2.07 pCi/l in 2009 and the control location concentration was 1.99 pCi/1. The 2008 indicator mean was 2.81 pCi/l. The table shows that current gross beta levels are not statistically different from preoperational concentrations.
0
- Tritium was detected in the four indicator samples and the four control samples during 2009.
The mean indicator tritium concentration for 2009 was 634 pCi/l, 3.17% of reporting level.
The mean control tritium concentration for 2009 was 681 pCi/l, 3.41% of reporting level.
- Figure 3.2 and Table 3.2 display the highest indicator and control location annual mean 0concentrations for tritium since 1984.
0 The concentration of tritium in drinking water is affected by releases from the Catawba plant and the McGuire Nuclear Station, located approximately 40 miles upstream of the Catawba
- plant on the Catawba River. Tritium in drinking water indicator samples was lower in 2009 than in previous years. During 2009, tritium released from Catawba was lower than the previous year due to a plant modification that was designed to capture Boron from the primary system. This modification is addressed in reference 6.14. Tritium was identified at the nearest drinking water location but was lower than tritium in the control location.
0Because of this, no dose from drinking water was attributed to releases from Catawba.
0 The dose for consumption of water was less than one mrem per year, historically and for 2009; therefore low-level iodine analysis is not required.

- 3.3 SURFACE WATER 0
A total of 39 monthly surface water samples was analyzed for gamma emitting radionuclides.
The samples were composited to create 12 quarterly samples for tritium analysis. Two 0indicator locations and one control location were sampled. One indicator location (208) is
- located near the liquid effluent discharge point.
0
- All 2009 indicator location samples contained tritium with an average concentration of 2292 pCi/l. Indicator Location 208 (Discharge Canal) showed a range of activities from 3530 to
- 4420 pCi/1 which had the highest mean concentration of 3930 pCi/l. Tritium was detected in
- all four control samples during 2009 with an average concentration of 529 pCi/l.
0 Gamma spectroscopy analysis detected Co-58 in four indicator samples and Co-60 in one indicator sample during 2009. Co-58 was detected at indicator location 208 and showed a range of Co-58 activities from 5.43 pCi/1 to 18.7 pCi/l with an average concentration of 9.40
- pCi/1 which represents 0.94% of the reporting level. Co-60 was detected at location 208 at
- 10.6 pCi/l which represents 3.53% of the reporting level. An investigation of these results
- was performed to document the review of sample collection and analysis methods and the review of effluent releases (reference 6.15). Co-58 and Co-60 were released in effluents from
- Catawba in 2009. Co-58 and Co-60 were also identified in a REMP sample in 2008. No 0problems were identified with the collection or analysis process. Gamma spectroscopy
- analysis has not detected any other activity in surface water samples since 1993. 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 tabular data did not Sreveal any increasing trends.

- Figure 3.3 displays the indicator and control annual means for tritium since 1984. Table 3.3 lists indicator annual means.
0The concentration of tritium in surface water is affected by releases from the Catawba plant
- and the McGuire Nuclear Station, located approximately 40 miles upstream of the Catawba plant on the Catawba River. Tritium in surface water indicator samples was lower in 2009 than in previous years. During 2009, tritium released from Catawba was lower than the previous year due to a plant modification that was designed to capture Boron from the

3.9 SHORELINE SEDIMENT 0
During 2009, a total of 6 shoreline sediment samples was analyzed, four from two 0 indicator locations and two from the control location.
0 Co-58 was identified in two samples and Co-60 was identified in one sample collected from indicator location 208-1S, which is closest to the plant's liquid effluent release 0 point. Cs-137 was identified in one sample collected from location 208-1S. Naturally occurring K-40 was identified in many of the indicator and control locations. Activity released in plant effluents has decreased since 1996 and as a result decreased activity has been measured in the environment.
0 0 The shoreline sediment location with the highest annual mean for all detectable radionuclides was location 208-1S. Co-58 was identified at location 208-1S with an 0 annual mean concentration of 110 pCi/kg. Co-60 was identified with an annual mean concentration of 104 pCi/kg. Cs-137 was identified with an annual mean concentration of 22.7 pCi/kg. Naturally occurring K-40 and Be-7 were also identified in samples from 0 this location.
0 Table 3.9 lists highest indicator location annual mean since 1984. Included in the table are radionuclides that have been identified in shoreline sediment samples since 1988.

Preoperational data and rolling ten year operational data averages 6 are also given. As shown in the graph, inner ring, outer ring, and control data averages 0I historically compare closely. Inner and outer ring averages comprise a number of data 6I points with control averages representing only three locations. 0I The calculated total body dose (from gaseous effluents) for 2009 was 1.54E0 mrem, 6I which is 1.93% of the average inner ring TLD values.

4.0 EVALUATION OF DOSE
- 4.1 DOSE FROM ENVIRONMENTAL MEASUREMENTS Annual doses to maximum exposed individuals were estimated based on measured 0concentrations of radionuclides in 2009 CNS 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 calculated using the methodology and data 0presented in NRC Regulatory Guide 1.109. Measured radionuclide concentrations, 0averaged over the entire year for a specific radionuclide, indicator location and sample type, were used to calculate REMP-based doses. Where applicable, average background concentration at the corresponding control location was subtracted. Regulatory Guide 1.109 consumption rates for the maximum exposed individual were used in the
- calculations. When the guide listed "NO DATA" as the dose factor for a given 0radionuclide and organ, a dose factor of zero was assumed.
0
- Maximum dose estimates (Highest Annual Mean Concentration) based on broadleaf vegetation, fish, and shoreline sediment sample results are reported in Table 4.1-A. The
- individual critical population and pathway dose calculations are reported in Table 4.1-B.
REMP-based dose estimates are not reported for airborne radioiodine, airborne
- particulate, milk, or ground water sample types because no radionuclides other than naturally occurring K-40 and Be-7 were detected in the samples. Dose estimates are not 0reported for surface water because sampled surface water is not considered to be a 0potable drinking water source although surface water tritium concentrations are used in calculating doses from fish. Exposure estimates based upon REMP TLD results are discussed in Section 3.10.
0The maximum enviroumental organ dose estimate for any single sample type (other than
- direct radiation from gaseous effluents) collected during 2009 was 3.61E-1 mrem to the maximum exposed child bone from consuming broadleaf vegetation.
0 4.2 ESTIMATED DOSE FROM RELEASES
- Throughout the year, dose estimates were calculated based on actual 2009 liquid and 0gaseous effluent 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 0corresponding REMP-based dose estimates. Summaries of RETDAS dose calculations 0are reported in the Annual Radioactive Effluent Release Report (reference 6.6).
0 0
O ~Section 4.-Page 1 0
0
0 The effluent-based liquid release doses are summations of the dose contributions from the drinking water, fish, and shoreline pathways. The effluent-based gaseous release 0 doses report noble gas exposure separately from iodine, particulate, and tritium exposure. For noble gas exposure there is no critical age group; as the maximum exposed individuals are assumed to receive the same doses, regardless of their age group. For iodine, particulate, and tritium exposure the effluent-based gaseous release doses are summations of the dose contributors from ground/plane, inhalation, milk and vegetation pathways.
0 4.3 COMPARISON OF DOSES The environmental and effluent dose estimates 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 environmental exposure pathways. This indicates that effluent program dose estimates are both valid and reasonably conservative.
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.
0 In calculations based on liquid release pathways, drinking water, fish, and shoreline sediment were the predominant dose pathways based on environmental and effluent data.
The maximum total organ dose based on 2009 environmental sample results was 7.OOE-3 mrem to the adult total body. The maximum total organ dose of 6.80E-2 mrem0 for liquid effluent-based estimates was to the adult GI-LLI.
In calculations based on gaseous release pathways, vegetation was the predominant dose pathway for effluent samples. The maximum total organ dose for gaseous effluent estimates was 1.54E0 mrem to the child's liver, total body, thyroid, kidney, lung, and GI-LLI. Vegetation was the predominant dose pathway for environmental samples. The maximum total organ dose for gaseous environmental estimates was 3.61E-1 mrem to the child bone.
Noble gas samples are not collected as part of the REMP, preventing an analogous comparison of effluent-based noble gas exposure estimates.
The doses calculated do not exceed the 40CFR190 dose commitment limits for members of the public. Doses to members of the public attributable to the operation of CNS are being maintained well within regulatory limits.

APPENDIX A S ENVIRONMENTAL SAMPLING AND 0 ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of all environmental media at Catawba Nuclear Station was required to ensure compliance with Station Selected Licensee Commitments. Analytical procedures were employed to ensure that Selected Licensee Commitments detection capabilities were achieved.
S Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, Fisheries and Aquatic Ecology.
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 procedure during 2009.
II. DESCRIPTION OF ANALYSIS PROCEDURES 0
Gamma spectroscopy analyses are performed using high purity germanium gamma detectors and Canberra analytical software. Designated sample volumes are transferred 0 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.
0 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 tritium spike 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.
0Samples are batch processed with a blank to ensure sample contamination has not 0occurred.
III. CHANGE OF ANALYSIS PROCEDURES 0
No analysis procedures were changed during 2009.
- IV. SAMPLING AND ANALYSIS PROCEDURES 0
A.1 AIRBORNE PARTICULATE AND RADIOIODINE 0Airborne particulate and radioiodine samples at each of five 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 and air particulate. A weekly gross beta analysis was performed on each filter. The continuous composite samples were collected from the locations listed below.
