SUMMARY

The H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP or Robinson Nuclear Plant) is operated by Duke Energy Progress, Inc. under a license granted by the Nuclear Regulatory Commission (NRC). Provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, HBRSEP Technical Specifications, and the HBRSEP Off-Site Dose Calculation Manual (ODCM) establish the requirements of the Radiological Environmental Monitoring Program (REMP). This report describes the HBRSEP REMP and the program results for January 1, 2014, through December 31, 2014.

Included in the report are the identification of sampling locations, descriptions of environmental sampling and analysis procedures, comparisons of present environmental radioactivity levels and pre-operational environmental data, analysis of trends in environmental radiological data as potentially affected by plant operations, and a summary of environmental radiological sampling results.

Quality assurance practices, sampling deviations, unavailable samples, and program changes are also discussed.

Sampling activities were conducted as prescribed by the HBRSEP ODCM.

Required analyses were performed and detection capabilities were met for the collected samples required by the ODCM.

One thousand four hundred and eleven samples were analyzed comprising 1,529 test results in order to compile data for the 2014 HBRSEP Annual Radiological Environmental Operating Report (AREOR).

Based on the annual HBRSEP land use census, the current number of sampling sites for Robinson Nuclear Plant is sufficient.

Concentrations observed in the environment in 2014 for plant related radionuclides were generally within the ranges of concentrations observed in the past. Inspection of the data showed that radioactivity concentrations were as expected and positively identified measurements attributable to plant operations were within limits as specified in the HBRSEP ODCM.

The continued operation of HBRSEP has not significantly contributed measurable radiation or the presence of gamma radioactivity in the environmental media monitored, with the exception of Lake Robinson bottom sediment and aquatic vegetation (both are used for long term trending with no dose contribution to the public). The Lake Robinson surface water samples and ground water samples revealed tritium concentrations that are well within the applicable regulatory limits.

2.0 INTRODUCTION

2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS Duke Energy's H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP) consists of a pressurized water reactor with a design rating of 800 MWe (Megawatts electric). The site is shared with a pulverized coal unit (Unit No.1), which established commercial operation in 1960. Unit 1 is now offline and is scheduled to be decommissioned. Commercial production was initiated by Unit No. 2 on March 7, 1971. The HBRSEP is located in Darlington County, South Carolina. The site is along state route 151 approximately five (5) miles northwest of Hartsville, South Carolina. The site is also approximately twenty five (25) miles northwest of Florence, South Carolina.

Lake Robinson is adjacent to the plant and is the source of cooling water. The lake was impounded during the construction of Robinson Unit No.1 (coal fired). The lake is fed by Black Creek and is approximately 2,250 acres in area. The plant intake is at the southern portion of the lake near the dam. The discharge is to a canal which conveys the cooling water to a point 4.2 miles north of the plant, where it returns to Lake Robinson.

The local economy supports primarily industrial and agricultural contributions.

Fishing, boating, and swimming are popular activities on Lake Robinson and other nearby lakes. These activities contribute to the radiological pathways by consumption of fish and immersion related to swimming and boating. Consumption of milk and food products contributes to the ingestion pathway. No milk animals are located within five miles of the plant in any sector at this time, so broadleaf sampling is conducted to simulate the milk ingestion pathway.

Although the contribution to background radiation is small, Duke Energy Progress, Inc. has established this program to measure the exposure pathways to man. An exposure pathway describes the source of the radiological exposure. The primary forms of potential radiological emissions from the plant are airborne and liquid discharge.

The following pathways are monitored: external dose, ingestion of radioactive materials, and the inhalation of radioactive material.

Specific methods and different environmental media are required to assess each pathway.

Sampling locations are chosen based upon meteorological factors, pre-operational monitoring, and results of the land use surveys. A number of locations are selected as controls. Control stations are selected because they are very unlikely to be affected by the operation of the plant.

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

Section 2 - Page 1

2.2 SCOPE AND REQUIREMENTS OF THE REMP The Radiological Environmental Monitoring Program (REMP) was established in 1973 at HBRSEP. Radiation and radioactivity in various environmental media have been monitored for 41 years. Monitoring is also provided for control locations, which would not be impacted by operations of the HBRSEP.

Using these control locations and data collected prior to operation allows comparison of data collected at locations near the HBRSEP which could potentially be impacted by its operations. The preoperational program provides data on the existing environmental radioactivity levels for the site and vicinity which may be used to determine whether increases in environmental levels are attributable to the station.

The operational 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.

This monitoring program is based on NRC guidance as reflected in the HBRSEP Off-Site Dose Calculation Manual (ODCM), with regards to sample media, sampling locations, sampling frequency and analytical sensitivity requirements.

Indicator and control locations were established for comparison purposes to distinguish radioactivity of plant origin from natural or other "man-made" environmental radioactivity. The environmental monitoring program also verifies projected and anticipated radionuclide concentrations in the environment and related exposures from releases of radionuclides from HBRSEP.

This program satisfies the requirements of Section IV.B.2 of Appendix I to 10 CFR 50 and provides surveillance of all appropriate critical exposure pathways to man and protects vital interests of the company, 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.

The Annual Land Use Census, required by the HBRSEP Off-Site Dose Calculation Manual (ODCM), 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 the requirements of Section IV.B.3 of Appendix I to 10 CFR 50. Results are shown in Table 3.12.3.

Participation in an interlaboratory comparison program is performed in fulfillment of HBRSEP ODCM Operational Requirements. The comparison program 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 10 CFR 50. A summary of the results obtained as part of this comparison program are in Section 4 of this annual report.

2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY 2.3.1 ESTIMATION OF THE MEAN VALUE There was one (1) basic statistical calculation performed on the raw data resulting from 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 generated by the sampling and analysis of the various media in the Radiological Environmental Monitoring Program. "Net activity (or concentration)" is the activity (or 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 used to estimate the mean (reference 6.8):

NYx, X

i=1 N

Where:

x = estimate of the mean, i = individual sample, N = total number of samples with a net activity (or concentration),

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

2.3.2 LOWER LIMIT OF DETECTION AND MINIMUM DETECTABLE ACTIVITY The Lower Limit of Detection (LLD), and Minimum Detectable Activity (MDA) are used throughout the REMP.

LLD - The LLD, as defined in the ODCM as 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 (before the fact) 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 ODCM and are listed in Table 2.2-C.

Section 2 - Page 3

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

2.3.3 TREND IDENTIFICATION 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 concentration 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 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 completely interpret the trends, or lack of trends, determined from the environmental data. 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 1986 Chernobyl accident and the 2011 Japan earthquake and tsunami which triggered the Fukushima Dai-ichi nuclear power plant incident). 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 The following section depicts and explains the review of the REMP results conducted during 2014 for the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP) and fulfills the reporting requirements of Technical Specifications and HBRSEP ODCM. Review of the 2014 REMP analysis results was performed to identify changes in environmental levels as a result of HBRSEP operations. Sample data for 2014 was compared to preoperational and historical data.

Evaluation for significant trends was performed for radionuclides that are listed as required within HBRSEP ODCM. 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.

HBRSEP ODCM addresses actions to be taken if radionuclides other than those required are detected in samples collected.

The occurrences of these radionuclides could be the result of HBRSEP liquid effluents which contained the radionuclides.

The purpose of the REMP is to measure accumulation of radioactivity in the environment, to determine whether this radioactivity is the result of the operation of the HBRSEP, Unit No. 2, and to assess the potential dose to the off-site population based on the cumulative measurements of radioactivity of plant origin. Approximately 1,411 samples were collected from indicator and control locations and 1,529 analyses and measurements were made during 2014. Detectable radioactivity resulting from plant operation was found in 24 out of 36 indicator samples of surface water (Appendix B). Only the tritium activity measured in the surface water of Lake Robinson and in fish samples constituted a source of public exposure. The highest concentration of any plant related radionuclide releases to the environment was tritium in Lake Robinson at an average concentration of 1.29E+3 pCi/Liter. Using the methodology of Regulatory Guide 1.109 "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I, Revision 1, dated October 1977," via fish consumption, is listed below. The maximum possible exposure to an individual from the evaporation of tritium in Lake Robinson using 2014 meteorology is 0.162 mrem/yr. to a child. Radioactivity in environmental samples attributed to plant operations in 2014 for which there is a potential dose pathway to the public is seen in Table 3.0-A.

The radiological environmental data for 2014 indicates that radioactivity concentrations were not higher than expected and positively identified measurements attributable to HBRSEP operations in 2014 were within limits as specified in the HBRSEP ODCM, thus presenting no significant Section 3 - Page 1

impact on the environment or public health and safety. A statistical summary of the HBRSEP data for 2014 has been compiled and summarized in Appendix B along with any plant-derived activity detected within the scope of the REMP.

3.1 AIRBORNE RADIOIODINE AND PARTICULATES The 518 air cartridge/radioiodine (AR) samples from indicator and control stations had 1-131 concentrations less than the ODCM LLD of 7.OOE-2 pCi/mi3. There are nine indicator sites for a total of 467 indicator samples and one control site for a total of 51 control samples during the 2014 collection year. The air samplers operated for a total of 99.79% availability for the 2014 year.

For the period of January 1, 2014, to December 31, 2014, the gross beta activity was detectable in the airborne particulate (AP) samples, with acceptable runtime, from the nine indicator locations and the control location. The 467 indicator samples had an average concentration of 1.70E-2 pCi/m3. Similar gross beta activities were observed at the control location in Florence, which had an average concentration of 1.63E-2 pCi/mi3 in 52 control samples. Figures 3.1-1 through 3.1-9 provide a graphic representation of the gross beta activity at the indicator locations compared to the control location for the year 2014.

No plant-related gamma activity was observed for any air particulate filters analyzed during 2014. The natural gamma concentrations identified are typical of the natural environment and are not attributed to plant operations. Refer to Appendix C or Appendix D for deviations and unavailable samples in the 2014 collection year.

No plant-related gamma activity was detected in quarterly composite filter samples from either the indicator or control locations during 2014. HBRSEP ODCM LLDs and reporting levels for air particulates are contained in Section 2.0 in Table 2.2-C and 2.2-A respectively.

3.2 SURFACE WATER Surface water (SW) composite samples are sampled monthly and analyzed for gamma emitting radionuclides and for tritium radioactivity.

The analyses indicated that no detectable concentrations of gamma - emitting radionuclides relating to plant effluents appeared in any of the indicator and control samples. All concentrations of natural occurring gamma-emitters were less than their respective LLDs (see Table 2.2-C). None of the control samples indicated the presence of tritium; however, 24 out of 36 indicator samples did indicate the presence of tritium in 2014. The average annual tritium activity was 1.29E+3 pCi/L, with the results ranging from 4.43E+2 pCi/L to 3.08E+3 pCi/L. The surface water indicator location with the highest tritium mean in 2014 was the Lake Robinson surface water (SW Black Creek at Old Camden Rd.)

with a mean of 1.50E+3 pCi/L, and results ranging from 6.64E+2 pCi/L to 3.08E+3 pCi/L; which is attributed to plant operation. Lake Robinson's tritium activity is cyclic and follows HBRSEP's fuel cycle. Figure 3.2-1 displays the tritium activity throughout 2014 for the surface water samples. These surface waters do not supply drinking water at any downstream location and are not typically used for irrigation. Therefore, radiological dose via this pathway (surface water) is limited to the consumption of fish (0.0033 mrem/yr.) and evaporation of tritium (0.162 mrem/yr. using RNP 2014 Meteorology Data) from Lake Robinson and its subsequent inhalation and ingestion from vegetable gardens and meat producing animals. Using the methodology of Regulatory Guide 1.109, a dose of 0.165 millirem/year to the maximum exposed individual could be assigned to this pathway.

3.3 GROUND WATER Ground water (GW) samples are collected and analyzed quarterly for gamma emitters and tritium. Some of the ground water samples are also analyzed for low-level radioiodine and for gross beta. No by-product/plant-related gamma activity associated with plant operations was detected in the fifty-eight (58) indicator samples of ground water collected in 2014.

The measured concentrations of the gamma analyses indicated concentrations below their required LLD as specified in the HBRSEP ODCM in Table 4.1-3 titled "Lower Limit of Detection (LLD)" for the year 2014 and Table 2.2-C of this report.

The ground water samples had detectable concentrations of tritium activity in twenty-two (22) out of fifty-eight (58) samples, for an average concentration of 6.06E+2 pCi/L; with a range of 1.90E+2 pCi/L to 1.76E+3 pCi/L.

The measured ground water tritium concentrations were below the required HBRSEP ODCM Table 4.1-3 LLDs for environmental samples and Table 2.2-C. The tritium limits are 2000 picocuries per Liter (pCi/L) for a drinking water pathway and 3000 pCi/L if no drinking water pathway exists. HBRSEP administratively established a ground water tritium analysis LLD of approximately 250 pCi/L, which is well below the requirements specified in the HBRSEP ODCM. These tritium results are also well below the EPA reportable drinking water limit (20,000 pCi/Liter) and the non-drinking water limit (30,000 pCi/Liter).

During 2014, eight (8) ground water indicator samples were analyzed for 1-131 to the HBRSEP ODCM drinking water limit (<1 pCi/L). No detectable concentrations of 1-131 activity were detected in the eight samples. Also during 2014, four (4) GW indicator samples were analyzed for gross beta activity, with activity present in three of the four samples, for an average concentration of 1.51 E+0 pCi/L, with a range of 1.23E+0 pCi/L to 1.84E+0 pCi/L.

In August of 2014, ground water ODCM location 71 (0.87 miles NNW [MW-03A] between Ash Pond and the Railroad tracks) was retired from the RNP REMP sampling program; however, it remains a ground water location in the RNP ODCM Rev. 33.

No indicator ground water samples, from location 71, were collected 3rd Quarter or 4th Quarter 2014. Refer to Appendix C for deviations and unavailable samples in the 2014 collection year.

3.4 MILK / BROADLEAF VEGETATION Milk monitoring has not been conducted due to the unavailability of milk samples in the area since July 17, 1998, when the dairy ceased operation. Milk sampling will resume if a new sample location is identified. Broadleaf sampling is conducted since no milk animals are located within a radius of approximately five miles of the plant in any sector and is used to calculate dose to an individual via the vegetation-milk-man pathway.

Broadleaf vegetation sampling is accomplished by collecting cherry, sassafras, and wax myrtle leaves in 2014. Three species of samples, when available, are collected monthly at five locations (one control and four indicator locations at the site boundary selected using historical meteorology with the highest calculated annual average ground level deposition). Broadleaf sampling is conducted since no milk animals are located within a radius of approximately five Section 3 - Page 9

miles of the plant and is used to simulate dose to an individual via the milk pathway for compliance purposes.

During 2014, 21 of 60 samples taken from the indicator sites demonstrated detectable concentrations of Cs-137 for an average value of 5.24E+1 pCi/kg (wet). The control samples had detectable concentrations of Cs-137 in 8 of 15 samples with a mean concentration of 5.51 E+1 pCi/kg (wet). Upon comparing these results, it is concluded that the indicator values reflect fallout Cs-137 contamination.

Past sampling experience further supports this interpretation. Refer to Appendix C and Appendix D for deviations and unavailable samples in the 2014 collection year.

3.5 FOOD PRODUCTS During 2014, two food product (FP) samples were collected from both the control location (FP-

49) and the indicator location (FP-58). Collards and tomatoes were collected from the control location (FP-49) and the indicator location (FP-58), while no food products were collected from indicator location FP-54 at Auburndale Plantation due to this area in 2014 not being irrigated by water in which liquid plant effluents have been discharged (see CR # 725966). No gamma activity associated with plant operation was detected in any control or indicator samples for the 2014 collection period.

3.6 AQUATIC VEGETATION The aquatic vegetation samples are considered to be sensitive environmental indicators used as long term trending and do not constitute a dose pathway. In 2014, there were three aquatic vegetation indicator samples and one aquatic vegetation control sample collected. The aquatic vegetation samples collected pose no radiological dose consequence since this is not a dose pathway to the general public. Gamma analyses of the aquatic vegetation samples detected no plant-related activity in any of the samples, other than natural occurring gamma activity.

3.7 FISH Samples of free-swimming and bottom-feeding fish were taken from Lake Robinson and Prestwood Lake (the first downstream lake) and compared to similar fish from a control lake, which is unaffected by plant operation. During 2014, 4 out of 4 bottom-feeding fish and 4 out of 4 free-swimming fish (indicator sites) demonstrated detectable concentrations of Cs-137 for an average value of 3.45E+1 pCi/kg (wet) and 4.04E+1 pCi/kg (wet), respectively. The control samples had detectable concentrations of Cs-137 for I out of 2 bottom-feeding fish and 2 out of 2 free-swimming fish for an average concentration of 1.89E+1 pCi/kg (wet) and 9.32E+1 pCi/kg (wet), respectively. Upon comparing these results, it is concluded that the 2013 indicator values reflect fallout Cs-137 contamination.

Past sampling experience further supports this interpretation.

Section 3 - Page 10

3.8 SHORELINE SEDIMENT In 2014, Cesium-137 activity was observed in one out of four indicator locations with a single concentration of 7.01 E+0 pCi/kg (dry). Only naturally occurring gamma activity was detected in the other three indicator locations. Cs-137 activity has been detected in shoreline sediment samples in past years, which was attributed to worldwide fallout and not the plant operation.

3.9 BOTTOM SEDIMENT During 2014, a total of three bottom sediment samples were analyzed from the indicator location and one from the control location.

The bottom sediment samples are used as indicators of buildup of radioactivity in the environment and do not constitute a dose pathway.

Cs-137 activity was detectable in two of the three indicator bottom sediment samples in 2014, with an average concentration of 2.96E+2 pCi/kg (dry). The control sample indicated detectable Cs-137 activity with a concentration of 1.70E+2 pCi/kg (dry). This concentration is similar to previous years and does not indicate a buildup in the environment. No other gamma activity, except for naturally occurring gamma activity, was detected in the annual bottom sediment samples in 2014.

3.10 ASIATIC CLAMS Benthic samples from Lake Robinson during 2014 continue to confirm the absence of any substantial populations of Asiatic clams (Corbiculafluminia). The natural chemistry of the lake (i.e., low alkalinity and hardness) inhibits their proliferation.

3.11 DIRECT GAMMA RADIATION 3.11.1 ENVIRONMENTAL TLD In 2014, 125 TLDs were analyzed, 122 at indicator locations and 3 at the control location.

TLDs are collected and analyzed quarterly.

Thermoluminescent dosimeters (TLDs) were used to monitor ambient radiation exposures in the plant environs.

The average quarterly exposure at the indicator and control locations was 16.5 mR/std. qtr. and 14.0 mR/std. qtr. respectively.

The highest TLD indicator location for 2014 was TLD location #35 at 4.5 miles SSW at Kelly Bridge Road

(#S-31-51) and its average was 23.3 mR/std. qtr. The differences among these locations are attributed to variations in soils, local geology, and are not the result of plant operations. There were four missing TLDs during the HBRSEP 2014 collection period, along with 43 TLDs (all of 4 th Quarter 2014 TLDs) classified as unavailable during the HBRSEP 2014 collection period (see Appendix C).

Section 3 - Page 11

The 4 th Quarter 2014 TLDs were put in the field and collected from the field as prescribed per procedure, but when the TLDs were analyzed the TLDs had elevated dose readings for both the control and indicator TLDs due to some type of exposure prior to the TLDs initially being put in the field.

The elevated TLD results are not included with the HBRSEP environmental results in Appendix E since they are not considered valid TLD results; however, the 4th Quarter 2014 TLD results can be found in Appendix G. This incident has been captured in the Duke Energy Corrective Action Program with CR #

731352 or PIP # G-15-00261. Additional information will be provided upon request.

Comparison of the quarterly TLD exposure within approximately I mile (inner ring) of the plant with that at approximately 5 miles (outer ring) is presented in Figure 3.11.1. These data illustrate that the quarterly inner ring TLD exposures for the three quarters of 2014 are slightly lower than the outer ring TLD exposures.

As of first quarter 2014, the environmental TLDs that are placed in the field for REMP are Harshaw TLDs. Panasonic TLDs were the type of environmental TLDs for HBRSEP REMP monitoring prior to 2014. This change was a merger initiative in order to achieve fleet standardization of the TLD program.

A TLD Intercomparison Program is conducted as part of the quality assurance program.

Results of this program are included in section 4.7.

3.12 LAND USE CENSUS The 2014 HBRSEP Annual Land Use Census was conducted in June, 2014 to meet the requirements of the HBRSEP ODCM 4.4.1. Table 3.12.3 summarizes the HBRSEP 2014 census results.

During the 2014 census no milk locations were identified within five miles (8 kilometers) of HBRSEP. Based on a review of sampling requirements, existing/new sample locations, and relative depositions values, no new environmental program changes were required as a result of the 2014 Land Use Census.

3.12.1 PURPOSE OF LAND USE CENSUS The land use census identifies the pathways (or routes) that radioactive material may reach the general populations near commercial nuclear generating stations.

This is accomplished by completing studies each year that identify how the surrounding lands are used by the population. A comprehensive census of the use of the land within a five-mile (8 kilometer) distance of the plant is conducted once per 12 months during the growing season.

This information is used for dose assessment and to identify changes to the stations sampled and the type of samples. These results ensure that the Radiological Environmental Monitoring Program (REMP) is based upon current data regarding human activity in the vicinity of the plant. Therefore, the purpose of the land use census is to ensure the monitoring program is current, as well as provide data for the calculation of estimated radiation exposure.

The pathways evaluated are:

Ingestion Pathway - Results from eating food products that may have radioactive materials deposited on them, incorporated radioactive materials from the soil or atmosphere. Another pathway is through drinking milk from local cows or goats, if these are present and if not then broadleaf vegetation is collected in lieu of milk. The grass used to feed these animals may have incorporated or had deposited on it radioactive materials that can be transferred to the milk.

Direct Radiation Exposure Pathway-Results from deposition of radioactive materials on the ground or from passage of these radioactive materials in the air.

> Inhalation Pathway-Results from breathing radioactive materials transported in the air.

3.12.2 METHODOLOGY The following must be identified within the five-mile (8 kilometer) radius of the plant for each of the sixteen meteorological sectors (compass direction the winds may blow, for example NNE [North North East]):

Section 3 - Page 13

The nearest resident The nearest garden of greater than 500 square feet, producing broadleaf vegetables

> The nearest milk animal

> The nearest meat/egg producing animal The primary methods are visual inspection from the roadside within the five (5) mile radius and personal contact with the individuals.

3.12.3 LAND USE CENSUS RESULTS The HBRSEP Land Use Census was performed June 2014 to meet the requirements of the HBRSEP's ODCM. The last HBRSEP land use census was performed in July 2013. The 2013 and 2014 results of the survey for the nearest resident, garden, milk and meat/egg producing animal for each meteorological sector are compared in Table 3.12.3.

No milk producing animals were identified within the five-mile radius of the site in any sector. Milk sampling will resume if a new sample location is identified. Vegetables like tomatoes, squash, okra, cucumbers, etc. are examples of the vegetables of choice for this area and are what is typically grown and sampled in the past.

Sampling of these vegetables (non-leafy) will continue until leafy vegetables can be identified. The results of the 2014 Land Use Census and 10 year average meteorological data were reviewed. No changes in release pathways were identified as a result of the land use census that would require an ODCM change, additional dose calculations, or procedure changes were identified.

4.5 DUKE ENERGY INTERLABORATORY COMPARISON PROGRAM In 2014 Duke Energy Environmental Laboratory (EnRad) participated in interlaboratory programs to satisfy Radiological Environmental Monitoring Program requirements in Duke Energy nuclear plant Offsite Dose Calculation Manuals and Selected Licensee Commitments Manuals, as applicable.

In addition, EnRad Laboratory participated in the Environmental Resource Associates (ERA)

RadCheMTm Proficiency Testing program to satisfy the North Carolina state drinking water radiochemistry certification requirements.

EnRad Laboratory participated in three interlaboratory programs: Eckert & Ziegler Analytics (EZA), ERA, and Fleet Scientific Services (FSS).

EZA results were evaluated against NRC Inspection Procedure 84750 (IP 84750) acceptance criteria.

ERA reported results were evaluated based on the National Environmental Laboratory Accreditation Conference (NELAC) Field of Proficiency Testing criteria. FSS results were evaluated as prescribed in the Duke Energy Nuclear Generation Procedure SRPMP 9-2.

A low-level Iodine-131 in water cross check was not performed during 2014, but was performed during 2013. A low-level Iodine-131 in milk cross check was performed during 2014. The preparation and analysis of both media (milk and water) for the low-level Iodine-131 analysis is accomplished using the EnRad procedure 54, Preparation of Samples for low-level 1-131 Analysis. Low-level Iodine-131 sample preparation and testing for both media is a similar process. A low-level Iodine-131 cross check in water is scheduled for the second quarter 2015 cross check program.

Low-level Iodine-131 analysis of water was not required during 2014 since the dose calculated for the consumption of the water was not greater than 1 mrem per year in any supported program (PIP G-15-00781 or CR # 744148).

4.5.1 DUKE ENERGY INTERCOMPARISON PROGRAM EnRad Laboratories participated in the Duke Energy Fleet Scientific Services (FSS) Intercomparison Program during 2014.

Interlaboratory cross check samples including gamma in water (Marinelli beakers), low-level 1-131 in milk, and tritium in water samples were analyzed during 2014. A summary of the EnRad Laboratory program results for 2014 is documented in Table 4.0-A.

4.5.2 ECKERT & ZIEGLER ANALYTICS CROSS CHECK PROGRAM EnRad Laboratories participated in the Eckert & Ziegler Analytics Cross Check Program during 2014. Cross check samples including air filters, air cartridges, gross beta in water, various gamma samples in Marinelli beakers (soil, vegetation, and milk), and Iodine in milk samples were analyzed at various times of the year.

A summary of the EnRad Laboratory program results for 2014 is documented in Table 4.0-B.

Section 4 - Page 2

4.5.3 ERA PROFICIENCY TESTING EnRad Laboratories performed method proficiency testing through a program administered by Environmental Resource Associates (ERA) of Arvada, CO.

ERA supplied requested method proficiency samples for analysis and nuclide concentration determination.

ERA reported proficiency test results to the North Carolina Department of Health and Human Services, North Carolina Public Health Drinking Water Laboratory Certification Program. A summary of these proficiency test data for 2014 is documented in Table 4.0-C.

4.6 SPLIT COMPARISON PROGRAM HBRSEP routinely participates in an environmental sample intercomparison program.

Program elements include sampling frequency and analysis for food products, shoreline sediments, surface water, fish, aquatic vegetation, and bottom sediment collected by HBRSEP Chemistry, Fisheries, and Aquatic Ecology.

Samples are routinely split with a vendor laboratory for intercomparison.

4.7 TLD INTERCOMPARISON PROGRAM 4.7.1 NUCLEAR TECHNOLOGY SERVICES INTERCOMPARISON PROGRAM Radiation Dosimetry and Records participates in a quarterly TLD intercomparison program administered by Nuclear Technology Services, Inc. of Roswell, GA.

Nuclear Technology Services irradiates environmental dosimeters quarterly and sends them to the Radiation Dosimetry and Records group for analysis of the unknown estimated delivered exposure.

A summary of the 2014 Nuclear Technology Services Intercomparison Report is documented in Table 4.0-D. The individual measurements were evaluated and results falling outside the acceptable ratio criteria had an evaluation performed to identify any recommended remedial actions and to reduce anomalous errors.

Complete documentation of any evaluation will be available and provided to the NRC upon request.

4.7.2 INTERNAL CROSSCHECK (DUKE ENERGY)

Radiation Dosimetry and Records participates in a quarterly TLD intracomparison program administered internally by the Dosimetry Lab. The Dosimetry Lab Staff irradiates environmental dosimeters quarterly and submits them for analysis of the unknown estimated delivered exposure.

APPENDIX A ENVIRONMENTAL SAMPLING ANALYSIS PROCEDURES Appendix A - Page I

APPENDIX A ENVIRONMENTAL SAMPLING AND ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of environmental media at the H.

B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP) was required to ensure compliance with provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, HBRSEP Technical Specifications, and the HBRSEP Off-Site Dose Calculation Manual (ODCM).

Analytical procedures were employed to ensure that the ODCM detection capabilities were achieved.

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

Section IV of this appendix describes the environmental sampling frequencies and analysis procedures by media type conducted in 2014.

I. CHANGE OF SAMPLING PROCEDURES Ground Water location 71 (0.87 miles NNW [MW-03A] between Ash Pond and the Railroad tracks) was retired from the REMP sampling program in August of 2014.

Therefore, no indicator ground water samples, from location 71, were collected 3 rd Quarter or 4th Quarter of 2014 (CR # 703262). This ground water well (location 71) remains a ground water location in the RNP ODCM Rev. 33.

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, food products, aquatic vegetation, and broadleaf vegetation are ground to achieve a homogeneous mixture and then transferred to an appropriate counting geometry.

Soil and sediment samples are dried, sifted to remove foreign objects (rocks, clams, glass, etc.), and then transferred to an appropriate counting geometry container. Once prepared for counting, EnRad's samples (fish, food products, aquatic vegetation, broadleaf vegetation, soils, and sediments) are analyzed by gamma spectroscopy.

Low-level iodine analyses are performed at the EnRad Laboratory 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 (water). The resin is then dried, mixed thoroughly, and a net resin weight determined before being transferred to an appropriate counting geometry and analyzed by gamma spectroscopy.

Appendix A - Page 2

Tritium analyses are performed monthly and 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.

Gross beta analysis is performed quarterly on a ground water sample by concentrating a designated aliquot of sample precipitate and analyzing it by Tennelec XLB Series 5 gas-flow proportional counters. Samples are batch processed with a blank to ensure sample contamination has not occurred.

III. CHANGE OF ANALYSIS PROCEDURES REMP analytical results reporting with 2 Sigma error was initiated during 2014, replacing the I Sigma error reporting (CR # 706771).

Low-level Iodine-131 (LLI-131) test components were modified to include only the LLI-131 component; all other components such as Berrylium-7 and Potassium-40 were removed (CR # 707736).

Gamma spectroscopy milk Iodine-131 MDA requirement was removed from the "GAMMAMILK" analysis as the required low-level Iodine-131 (LLI-131) requirement is satisfied by the "GAMMALLI" LLI-131 preparation and testing procedure and gamma spectroscopy analysis (CR # 721898).

The gamma spectroscopy system was replaced during 2014 (1OJUL2014).

Gamma spectroscopy system hardware, detector cooling apparatus, software, electronics, nuclide identification libraries, and analytical test matrix components for test matrices were modified (CR # 739995).

As of first quarter 2014, the environmental TLDs that are placed in the field for REMP are Harshaw TLDs. Panasonic TLDs were the type of environmental TLDs for REMP monitoring prior to 2014. This change was a merger initiative in order to achieve fleet standardization of the TLD program.

IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE AND RADIOIODINE Airborne particulate (AP) and radioiodine (AR or AC) samples at each of ten 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 sample head.

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 Appendix A - Page 3

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 and then the filters were composited to produce quarterly filter samples for gamma analysis.

The continuous composite samples were collected from the locations listed below.

Thermoluminescent dosimeters (TLD) were collected quarterly at forty-three locations.

A gamma exposure rate was determined for each TLD.

TLD locations are listed in Table 2.1-B. The TLDs were placed as indicated below.

An inner ring of 25 TLDs, one in each meteorological sector in the general area of the site boundary.

An outer ring of 17 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 at a control location.

A.11 ANNUAL LAND USE CENSUS An Annual Land Use Census was conducted to identify within a distance of 5.0 miles (8 kilometers) from the plant, the nearest location from the site boundary in each of the sixteen meteorological sectors, the following:

The Nearest Residence The Nearest Garden greater than 500 square feet or 50 square meters, producing broadleaf vegetables (fresh leafy vegetables)

The Nearest Milk-giving Animal (cow, goat, etc.)

The Nearest Meat/Egg producing Animal (beef, hogs, chickens, etc.)

Appendix A - Page 7

The census was conducted during the growing season in June of 2014. Results are shown in Table 3.12.3. No changes were made to the sampling procedures during 2014 as a result of the 2014 census.

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.

Three types of broadleaf vegetation samples are collected monthly when available from four locations for a possible total of 144 samples.

6.

Bottom sediment and aquatic vegetation sampling are not required by plant Offsite Dose Calculation Manual (ODCM). Sampling and analysis is performed to monitor any radionuclide accumulation in the lake.

7.

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

8.

Tritium Lower Limit of Detection (LLD) is approximately 2.50E+2 pCi/L for samples that typically demonstrate activity less than the LLD. The LLD was lowered in order to maintain comparable LLD and result values with the NC Division of Radiation Protection (NCDRP) Laboratory.

9.

TLD results for 4 th Quarter 2014 are not included in the Data Summary in Appendix B due to invalid results due to an external exposure (See Appendix C, G, and CR # 731352 or PIP # G-15-00261).
