SUMMARY

The Harris Nuclear Plant (HNP) is operated by Duke Energy Progress, LLC under a license granted by the Nuclear Regulatory Commission (NRC). Provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, Harris Nuclear Plant Technical Specifications, and the Harris Nuclear Plant Offsite Dose Calculation Manual (ODCM) establish the requirements of the Radiological Environmental Monitoring Program (REMP).

This report describes the HNP REMP and the program results for January 1, 201 7, through December 31, 2017.

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 Harris Nuclear Plant ODCM.

Required analyses were performed and detection capabilities were met for the collected samples required by the ODCM. One thousand four hundred and thirty-four samples were analyzed comprising 1,695 test results in order to compile data for the 2017 HNP Annual Radiological Environmental Operating Report (AREOR). Based on the annual HNP land use census, the current number of sampling sites for Harris Nuclear Plant is sufficient.

Concentrations observed in the environment in 201 7 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 all positively identified measurements attributed to plant operations were within the HNP ODCM regulatory limits.

The continued operation of HNP has not contributed measurable radiation or the presence of gamma radioactivity, with the exception of Harris Lake bottom sediment and the aquatic vegetation, in the environmental monitoring program. The Harris Lake Surface water samples and the 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 Harris Nuclear Plant consists of a pressurized water reactor with a net output of approximately 930 MWe (Megawatts electric). Commercial production was initiated on January 3, 1987. HNP is located in southwest Wake County, North Carolina. The site is along U.S. route 1 approximately sixteen (16) miles southwest of Raleigh, North Carolina and approximately fifteen (15) miles northeast of Sanford, North Carolina. The nearest community is New Hill, North Carolina, which is north of the site.

Harris Lake is adjacent to the plant itself and is the source of cooling tower makeup water. The lake was impounded during the construction of the Harris Plant. The lake is fed by Buckhorn

Creek and is approximately 4,400 acres in area. The main dam is approximately 4.7 miles south of the site. The primary discharges to Harris Lake from the plant are surface runoff, cooling tower blowdown, and radiological waste process systems.

Fishing, boating, and swimming are popular activities on Harris Lake and other nearby lakes. Duke Energy Progress, LLC encourages the recreational use of the lake, Harris Lake County Park, and the adjoining lands through a variety of agreements with state and local government.

Within a five

-mile radius, most of the land is wooded with only a few residences and limited agricultural activity. There are no residences on the plant site. The chief use of land is for production of timber and pulp fiber.

Within a ten

-mile radius, the area is considered rural with significant populations in Apex, Holly Springs, and Fuquay - Varina. Currently, these communities are experiencing significant growth.

Within a fifty

-mile radius, much of the land is used in agricultural production with significant crops including corn, soybeans, and tobacco. Livestock is also an important component with significant production in cattle, hogs, poultry, and dairy products.

Consumption of drinking water, food crops, and fish are sample media that are examples of ingestion pathways for exposure. Although the contribution to background radiation is small, Duke Energy Progress, LLC has established the Radiological Environmental Monitoring Program (REMP) to measure the exposure pathways to man.

An exposure pathway describes the source of the radiological exposure. The primary forms of 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, preoperational monitoring, and results of the land use surveys. A number of locations are selected as controls. Control locations are selected because they are unaffected by the operation of the plant. Figures 2.1-1, Section 2 - Page 2 2.1-2, 2.1-3, and 2.1-4 are maps depicting the HNP REMP sampling locations and the Thermoluminescent Dosimeter (TLD) monitoring locations. The location numbers shown on these maps correspond to those listed in Tables 2.1-A, 2.1-B, and 2.1-C. 2.2 SCOPE AND REQUIREMENTS OF THE REMP The Radiological Environmental Monitoring Program (REMP) was established in 1982 at the Harris Nuclear Plant (HNP). Radiation and radioactivity in various environmental media have been monitored for 3 5 years, including 5 years prior to commencing operation. Monitoring is also provided for control locations, which would not be impacted by operations of the HNP.

Using these control locations and data collected prior to operation allows comparison of data collected at locations near the HNP, 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.

This monitoring program is based on NRC guidance and is conducted in accordance with Operational Requirement 3.12.1 in the HNP Offsite Dose Calculation Manual (ODCM) and applicable procedures; 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. This program 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 HNP Offsite 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 3.12.3-1.

Participation in an interlaboratory comparison program is performed in fulfillment of HNP 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.

Section 2 - Page 3 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: x = N N i i x1 Where: x = estimate of the mean, i = individual sample, N = total number of samples with a net activity (or concentration), i = 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" LLDs for each sample medium and selected radionuclides are given in the ODCM and are listed in Table 2.2

-C.

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

Section 2 - Page 4 calculated using a sample background and may be thought of as an "actual" LLD for a particular sample measurement. Certain gross counting measurements display a calculated negative value, indicating background is greater than sample activity.

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 plant.

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 Chernobyl accident and the 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.

Section 3 - Page 1 3.0 INTERPRETATION OF RESULTS

The following section depicts and explains the review of the REMP results conducted during 2017 for the Harris Nuclear Plant (HNP) and fulfills the reporting requirements of Technical Specifications 6.9.1.3 and HNP ODCM E.3. Review of the 2017 REMP analysis results was performed to identify changes in environmental levels as a result of HNP operations. Sample data for 2017 was compared to preoperational and historical data.

Evaluation for significant trends was performed for radionuclides that are listed as required within the HNP ODCM. The radionuclides include: H

-3, Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, I-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 plant operation, but not required for reporting, are trended.

The HNP 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 HNP liquid effluents which contained the radionuclides.

Review of the 2017 data presented in this section supports the conclusion that there were no significant changes in environmental sample radionuclide concentrations of samples collected and analyzed from HNP and surrounding areas that were attributable to plant operations. Inspection of the data showed that radioactivity concentrations were as expected and all positively identified measurements attributed to plant operations were within HNP ODCM regulatory limits; thus presenting no significant impact to the environment or public health and safety.

A statistical summary of the HNP data for 2017 has been compiled and summarized in Appendix B along with any plant

-derived activity detected within the scope of the REMP. No detectable tritium activity was observed at Lillington, N.C., located 17 miles downstream on the Cape Fear River, which is the first public drinking water (ingestion pathway) location below the Harris Lake discharge spillway. No plant

-related gamma activity has been detected in fish collected from Harris Lake or in the water samples from Lillington, N.C. The Harris Lake bottom sediment and aquatic vegetation detected plant

-derived gamma activity, but pose no radiological dose to the general public via this pathway due to the fact that the bottom sediment is not easily accessible and aquatic vegetation is not an ingestion pathway. Bottom sediment samples are for long-term trends. 3.1 AIRBORNE RADIOIODINE AND PARTICULATES The 477 air cartridge/radioiodine (AC) samples from indicator and control stations had I

-131 concentrations less than the ODCM LLD of 7.00E-2 pCi/m 3. The air samplers Section 3 - Page 2 operated for a total of 99.93% availability for the 201 7 year. N o I-131 activity due to HNP operations has been detected in air samples collected from 1987 through 201 7 , which is the entire operating history of the plant.

However, I-131 was detected in air samples for a three

-week period following the Fukushima Dai

-ichi Nuclear Power Plant incident after the March 11, 2011, earthquake and tsunami (NCR # 0456564) and for a six-week period following the Chernobyl incident in April 1986. Refer to Table 3.1-1-B for the highest annual mean indicator location and control location I

-131 concentrations since 1999 to 2017.

For the period of January 1, 201 7, to December 31, 201 7, the gross beta activity was detectable in the airborne particulate (AP) samples, with acceptable runtime, from the eight indicator locations and the one control location. The 424 indicator samples had an average concentration of 2.02E-2 pCi/m 3 , a value slightly higher than the preoperational data of 2.00E

-2 pCi/m 3. Similar gross beta activities were observed at the control location in Pittsboro, which had an average concentration of 2.05E-2 pCi/m 3 in 53 control samples. Figure 3.1-1 and Table 3.1-1-A provide individual sample gross beta results for the highest annual mean indicator location and the control location concentrations since 1999 to 201 7 (refer to Appendix B). The two sample locations' results are similar in concentration and have negligible variance. The HNP 2010 gross beta result for the

highest annual mean indicator location in Figure 3.1

-1 and Table 3.1-1-A was elevated due to this location being a new air sampler location (end of July 2010) with less than half the annual samples (22 instead of 52). This new location is near a new gravel road which receives a lot of travel due to construction in the area.

No plant-related gamma activity was observed for any air particulate filters analyzed during 201

7. 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 2017 collection year.

No plant-related gamma activity was detected in quarterly composite filter samples from either the indicator or control locations during 201

7. HNP 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 DRINKING

WATER Low-level Iodine

-131 analysis of drinking water was not required during 201 7 since the dose calculated for the consumption of the water was not greater than 1 mrem per year in any supported program. This dose was calculated monthly during 201 7 to ensure that low-level Iodine

-131 analysis of drinking water samples was not required

. The water samplers operated for a total of 99.

47% availability for the 201 7 year. Refer to Appendix C or Appendix D for deviations and unavailable samples in 201 7 collection year, if applicable.

The average annual gross beta concentrations at the indicator and control locations were

3.61E+0 pCi/L and 4.44E+0 pCi/L, respectively. The preoperational average was 4.00E+0 pCi/L. These concentrations are attributed to the natural environment and are not attributed to plant operations. Figure 3.2-1 and Table 3.2-2 show individual gross beta results for the highest annual mean gross beta concentration for indicator and control locations since 1999 to 2017.

Analyses for gamma

-emitting radionuclides from plant operations indicated concentrations were less than the lower limit of detection for drinking water. Table 2.2-C contains ODCM LLD values for gamma-emitting radionuclides in drinking water.

Tritium concentrations in the Lillington Municipal Water Supply samples (DW/SW-40) were less than the ODCM LLD (2000 pCi/L) and the administrative limit (200 pCi/L)

Section 3 - Page 5 (see Appendix B, Footnote 7). The annual average tritium concentration for the Water Treatment Building sample on site (DW-51) was 4.

02E+3 pCi/L, with a minimum and maximum value of 3.03E+3 pCi/L and 5.84E+3 pCi/L, respectively. Figure 3.2

-2 and Table 3.2-2 display the highest annual mean indicator and control location concentrations for tritium since 1999 to 201

7. Prior to 2009, DW

-51 was not classified as a public drinking water source nor as a HNP REMP drinking water indicator location. In 2009, DW-51 was added to the HNP REMP as a drinking water indicator sample and it was classified as a public water source; however, it is not a community drinking water source.

The concentrations of man

-made gamma

-emitters were less than their respective lower limits of detection (see Table 2.2-C). The annual average tritium concentration in Harris Lake at the Spillway was 5.

98E+3 pCi/L with minimum and maximum values of 4.42E+3 pCi/L and 9.12E+3 pCi/L, respectively. The average Harris Lake Spillway (SW

-26) tritium concentration is comparable to the previous tritium average of 5.68E+3 pCi/L in 201

6. This concentration remains well below the tritium regulatory limits. Figure 3.3-2 and Table 3.3-2 display the tritium results for the highest annual mean concentrations for indicator and control locations since 1999 to 2017.

Average gross beta concentrations at the indicator and control locations were 3.9 7E+0 pCi/L and 4.05E+0 pCi/L, respectively, in 201 7, indicating no contribution from plant operations. Figure 3.3-1 and Table 3.3-2 display individual gross beta results for the highest annual mean gross beta concentration for indicator and control locations since 1999 to 2017.

The measured ground water gamma and tritium concentrations were below the required HNP ODCM Table 4.12

-1 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.

HNP administratively established a ground water tritium analysis LLD of approximately 2 00 pCi/L, which is well below the requirements specified in the HNP ODCM.

The ground water tritium analysis shows the presence of tritium, ranging from 1.99E+2 pCi/Liter to 1.17E+3 pCi/Liter in 201 7; however, the results are well below the EPA reportable drinking water limit (20,000 pCi/Liter) and non

-drinking water limit (30,000 pCi/Liter). The ground water wells, located on site at HNP, are monitoring wells and are not a water supply for drinking or irrigation. Therefore, there is no radiological dose via this pathway.

3.5 MILK/BROADLEAF VEGETATION During 201 7, as in the past years with the exception of the 1986 Chernobyl incident and the 2011 Japan earthquake and tsunami which triggered the Fukushima Dai

-ichi Nuclear Power Plant incident (N CR #0458543), no I-131 activity w as detected in the control milk sample. This control milk location is located greater than 12 miles WNW from the plant, thus in an area to be out of the influence of the plant. Gamma analyses revealed no detectable radioactivity from plant operations. Natural gamma activity is consistently identified in each control milk sample along with other natural ly occurring nuclides.

From 2010 to 2013, a small local goat dairy, Humbug Farm Milk # 96, provided goat milk samples during the spring and summer months. In 2013, Humbug Farm ceased operation (NCR # 0604191). ODCM Rev. 26 removed this location from the Radiological Environmental Monitoring Program. Maple Knoll Dairy was removed form the program in 1997. New milk animals (goats) were identified within the five mile radius of HNP during the 2016 HNP Land Use Census conducted August 2 - 4, 2016 in the W sector at 2.82 miles. The family has indicated that they could possibly participate by providing goat milk samples for analysis from late

-Spring to late

-Fall. This will be Milk Indicator location # 102. The sampling started semi

-monthly in November 2016 and ran through middle of December 2016. This sample location was added to the HNP ODCM Rev. 27 effective June 15, 2017

. Fifteen indicator milk samples were collected in 2017.

In lieu of the monthly milk samples, per HNP ODCM Table 3.12-1, indicator broadleaf vegetation samples were collected in both the SW and SSW sectors. Broadleaf sampling is conducted to simulate dose to an individual via the milk pathway for compliance purposes. Broadleaf vegetation sampling is accomplished by collecting monthly, three different species of samples, when available during the growing season (May through October), at two locations at the site boundary (two indicator locations of the highest predicted annual average ground level D/Q) and at the control location (BL

-5 in the Section 3 - Page 10 NNW sector at greater than 12 miles).

As of the 2017 broadleaf vegetation growing season (May through October), HNP broadleaf vegetation samples went to one mixed broadleaf vegetation (three types of broadleaf vegetation) per site instead of three separate types of broadleaf vegetation samples per site. This change was due to a lack of sufficient sample volume of each broadleaf vegetation type, which meets the HNP ODCM broadleaf vegetation sampling requirements. The gamma analyses on the broadleaf vegetation did not detect any plant

-related radioactivity in any of the six control and twelve indicator broadleaf vegetation samples (mixed broadleaf vegetation) in 201

7. Refer to Appendix C or Appendix D for deviations and unavailable samples in the 201 7 collection year, if applicable.

3.6 FOOD PRODUCTS None of the gardens identified during past or present annual Land Use Census are irrigated by water in which liquid plant wastes have been discharged; therefore, food product collection is not required. There is no indicator location for this media type and sampling at a control location is maintained for historical integrity. In November 2014, a new food product control location #97 at the Granite Springs Farm (19.1 miles in NW sector) was officially introduced to the REMP to be sampled along with control location #5. However, during the 2016 growing season, no food crops from location #5 were collected due to the lack of availability (NCR # 0727501). Location # 5 food product or food crop was deleted from the HNP ODCM with Revision 26 effective 9/23/16.

In addition to milk sampling (or broadleaf vegetation sampling), a food product sampling program was maintained. Various crops were collected during the growing season(s),

which continued year round. The species selected were primarily broad

-leaf vegetables, which are most sensitive to direct fallout of airborne radioactive particulates. Gamma analyses of the food products detected no plant

-related activity in any of the thirty-six samples from control location #97 collected in 201

7. Refer to Appendix C or Appendix D for deviations and unavailable samples in the 2017 collection year.

3.7 AQUATIC

VEGETATION The 201 7 data shows that there were fo ur aquatic vegetation indicator samples and tw o control samples collected from Harris Lake, which are sampled annually. The aquatic vegetation samples (Lyngbya and Hydrilla) from Harris Lake are not consumed by humans, thus pose no radiological dose to the general public by the ingestion pathway.

Gamma analyses of the aquatic vegetation detected plant

-related activity in the four indicator samples and the two control samples collected during 201

7. The 2017 data shows the average concentration at the indicator and control locations , where Co-60 was 1.45E+1 pCi/kg wet and less than LLD respectively and Cs

-137 was 8.99E+0 pCi/kg wet and 9.51E+0 pCi/kg wet respectively (NCR # 02162038). No long-term trends have been readily observed in these samples.

Section 3 - Page 11 3.8 FISH Analyses for gamma

-emitting radionuclides in four samples of bottom

-feeding species (catfish) and in eight samples of free

-swimming species (sunfish and largemouth bass) from the indicator and control locations revealed no detectable activity for 201 7, other than naturally occurring nuclides. This is consistent with the data for 1989-2016. During the Chernobyl period, Cs

-134 and Cs

-137 were detected in both control and indicator fish samples. 3.9 SHORELINE SEDIMENT Shoreline sediment samples were collected semiannually in 201 7 from opposite the discharge structure and near the main dam. Gamma analyses of the shoreline sediments detected natural activity in the samples collected during 201

7. No long

-term trends are readily observed in these samples.

3.10 BOTTOM SEDIMENT During 201 7, a total of two bottom sediment samples were analyzed from the indicator location. There is no control bottom sediment sample.

The 201 7 data shows Co-58 (4.01E+1 pCi/kg dry), Co-60 (2.14E+2 pCi/kg dry), and Cs-137 (8.35E+1 pCi/kg dry) activity in the indicator samples, which are sampled semiannually. The bottom sediment sample from Harris Lake poses no radiological dose to the general public via this pathway due to the fact that it is not easily accessible (i.e.

bottom sediment is approximately forty to sixty feet underwater). These samples are for long-term trends for liquid effluents.

Figure 3.10

-1 and Table 3.10

-1 provide individual sample gamma results for the highest annual mean indicator location concentrations since 1999 to 2017 for Co-60 and Cs-137 (refer to Appendix B).

TLDs are collected and analyzed quarterly. Since the inception of the HNP REMP, the regional population has moved closer to the plant and TLD locations 3 and 50 are the new Special Interest locations per HNP ODCM Revision 26 effective 9/23/16.

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 14.

4 mR/Std. Qtr. and 1 5.9 mR/Std. Qtr. respectively. The highest indicator location was 2.0 miles NW of the plant and its average was 17.9 mR/Std. Qtr. The differences among these locations are attributed to variations in soils, local geology, and are not the result of plant operations.

S ix TLDs were missing from different designated locations during the 2017 calendar year. No trends were identified and all TLD surveillance requirements were met for 2017 (see Appendix C).

Comparison of the average annual TLD exposure within approximately 2 miles (inner ring) of the plant with that at approximately 5 miles (outer ring) and the control for 1999 to 2017 is presented in Figure 3.11-1 and Table 3.11-1.

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. This change in environmental TLDs for the REMP indicates a step change in activity as mentioned in NCR # 01982479 between the Panasonic TLD readings prior to 2014 and the Harshaw TLD readings from 2014 to present. There are three factors that can be attributed to the step increase that was observed: (1) the annealing method levels employed were lower for the Panasonic TLDs, (2) transit control subtraction differences, and (3) the calculation/method of fade correction (fixed fade control -

vs - actual in field TLDs). Data accrual began in 2016 for enhanced analytical methods which will be evaluated for future implementation when sufficient data is available. The new methods will improve data transparency and interpretation.

A TLD intercomparison program is conducted as part of the quality assurance program. Results of this program are included in Section 4.7.

Section 3 - Page 15 3.12 LAND USE CENSUS The 201 7 HNP Annual Land Use Census was conducted August 22 through 23 , 201 7, as required by the HNP ODCM 4.12.2. Table 3.12.3

-1 summarizes the comparison between the 201 6 and 201 7 census results. A map indicating identified locations is shown in Figure 3.12.3

-1. During the 201 7 census, no irrigated gardens were identified within fiv e miles (8 kilometers) of HNP.

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 completed during the growing season each year. 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 crops that may have radioactive materials deposited on them, incorporated radioactive materials from the soil or atmosphere. Another pathway is through drinking milk or eating goat cheese 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.

Section 3 - Page 16 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]):

The nearest resident The nearest garden of greater than 500 square feet, producing broadleaf vegetables The nearest milk 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 2016 and 2017 results of the survey for the nearest resident, garden, milk and meat animals in each sector are compared in Table 3.12.3-1.

The nearest resident, garden, and meat animal in each sector remained the same from 2016 to 2017, except for the changes indicated in Table 3.12.3-1. In 2017, no resident, garden, meat or milk animal were located within 5 miles of the plant for the South (S) sector. Milk goats were found in the N and W sectors in 201

7.

• Represents a change from the previous year.

--- Indicates no occurrences within the 5 mile radius (1) Meat animal was only identified at the nearest garden or closer in each sector.

Poultry and egg laying animals were not classified as meat animals for the 2017 census.

(2) Goat Milk - Milk is used to feed goat kids, make a small quantity of cheese, and to make soap for personal use. Owner said they can now supply enough milk to participate in the HNP REMP.

This dairy is not required due to HNP already having a dairy within 5 km (3.11 miles) and the dose being <1.0 mRem/year.

(3) Goat Milk - Milk is used to feed goat kids during the breeding months and the family consumes what is left. The milk that is not suitable for consumption is given to someone to make soap. This location participates in the REMP and milk is collected for 4 - 6 consecutive months per year (Late

-Spring to Late

-Fall months).

Section 4 - Page 2 4.5 DUKE ENERGY INTERLABORATORY COMPARISON PROGRAM In 201 7 Duke Energy Environmental Laboratory (EnRad) participated in an interlaboratory program to satisfy Radiological Environmental Monitoring Program requirements in Duke Energy nuclear plant Offsite Dose Calculation Manuals and Selected Licensee Commitments Manuals, as applicable. The EnRad organization, in 2017, elected to voluntarily withdraw its North Carolina State Drinking Water Certification with the North Carolina Department of Health and Human Services, State Laboratory of Public Health. It was determined that there was no longer a business case for maintaining this certification (NCR # 02093309). Samples requiring this certification are sent to General Engineering Laboratories, LLC (GEL), which maintains the necessary certifications to meet regulatory commitments for drinking water.

EnRad Laboratory participated in an interlaboratory program with Eckert & Ziegler Analytics (EZA) in 2017. EZA results were evaluated against the NRC Inspection Manual Procedure 84750 (IP 84750) acceptance criteria stated in EnRad Procedure 515, Cross Check Program Administration. All regulatory requirements continue to be met by the EZA Cross Check Program.

4.5.1 DUKE ENERGY INTERLABORATORY PROGRAM EnRad Laboratories made the determination in 2017 to discontinue its participation in the Duke Energy Fleet Scientific Services (FSS) Interlaboratory Program, as EnRad already maintains a sufficient cross check program through EZA. Historically, Duke Energy FSS has maintained its own Interlaboratory Program supporting the Duke Energy fleet. At EnRad, this has been a supplement to EnRad's participation in the EZA Cross Check Program. In 2017, FSS determined that shifting business needs had reduced the need for the FSS Interlaboratory Program and the majority of the Interlaboratory Program has been discontinued.

4.5.2 ECKERT

& ZIEGLER ANALYTICS CROSS CHECK PROGRAM EnRad Laboratories participated in the Eckert & Ziegler Analytics (EZA) Cross Check Program during 201

7. Cross check samples including mixed gamma in liquid, mixed gamma in vegetation, low

-level I-131 in liquid, mixed gamma air filters (single and composites), mixed gamma and I-131 air cartridges, strontium in water, gross alpha and beta in water, gross alpha and beta in filters, and tritium in water were analyzed at various times of the year. A summary of the EnRad Laboratory program results for 2017 is documented in Table 4.0-A.

Interlaboratory cross check samples from EZA were received and analyzed in all four quarters of 2017. Table 4.0-A lists the performance for specific samples. Eighty-seven nuclide results were reported to EZA of which eighty-six (98.9%) met the acceptance criteria based on IP 84750.

One EZA cross check nuclide result did exhibit a high bias and EnRad proactively initiate d an NCR to investigate th is bias.

Section 4 - Page 3 In the second quarter of 2017, a mixed gamma in filter cross check (E11890) yielded a disagreement on only the Zinc 65 nuclide value (ratio to the known of 130%). An overall high bias was noted across all other nuclides, primarily in the high energy range. NCR # 02138003 was written to investigate and document the failure. It was determined that the geometry used for gamma filter counting contained compounding biases, leading to consistently high results in the upper energy range. Following the implementation of a new filter geometry, an equivalent filter cross check (E12011) was analyzed in the fourth quarter of 2017.

The cross check passed with reduced biases, and a Zinc-65 nuclide value of 111%

of the known.

4.5.3 ERA PROFICIENCY TESTING EnRad Laboratories made the determination in 2017 to discontinue its participation in the Environmental Resource Associates (ERA) Proficiency Testing program, as this program's participation was solely for the purpose of maintaining EnRad's North Carolina State Drinking Water Certification requirements (NCR # 02093309).

4.6 STATE

OF NORTH CAROLINA INTERCOMPARISON PROGRAM EnRad Laboratories routinely participates with the North Carolina Department of Health and Human Services in an intercomparison program. EnRad Laboratories sends Harris Nuclear Plant Radiological Environmental Monitoring Program air, drinking water, surface water, milk, fish, food products, ground water, and shoreline sediment samples to the North Carolina Department of Health and Human Services, Division of Public Health for intercomparison analysis. 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 2017 Nuclear Technology Services Intercomparison Report is documented in Table 4.0-B. 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. During first quarter of 201 7 an environmental external TLD cross check failed and NCR # 021 47847 was written to document the failure of the four individual TLDs; however, the overall result fell within both the Duke Energy and Nuclear Technology Services, Inc.

acceptance criteria. To prevent recurrence, the four TLDs were pulled and visually inspected for abnormalities in the elements and overall integrity of the TLDs and no abnormalities were found. The four TLDs were checked per procedure and Section 4 - Page 4 TLDs # 53 3830 and 103 632 were both removed from service. Complete documentation of any evaluation will be available and provided to the NRC upon request. 4.7.2 INTERNAL CROSS CHECK (DUKE ENERGY)

Radiation Dosimetry and Records participates in a quarterly TLD internal comparison 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. A summary of the 201 7

Internal Cross Check (Duke Energy) Program is documented in Table 4.0-B.

APPENDIX A ENVIRONMENTAL SAMPLING

& ANALYSIS PROCEDURES

Appendix A - Page 2 APPENDIX A ENVIRONMENTAL SAMPLING AND ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of environmental media at the Harris Nuclear Plant (HNP) was required to ensure compliance with provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, Harris Nuclear Plant Technical Specifications, and the Harris Nuclear Plant Offsite Dose Calculation Manual (ODCM). Analytical procedures were employed to ensure that the ODCM detection capabilities were achieved.

Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, Environmental Water Resources Group, and General Engineering Laboratories, LLC (vendor lab).

This appendix describes the environmental sampling frequencies and analysis procedures by media type.

I. CHANGE OF SAMPLING PROCEDURES Control location

1. 038 (Drinking Water/Surface Water - at Cape Fear Steam Electric Plant water intake structure in the WSW sector) was deleted from the HNP REMP per

HNP ODCM Rev. 27 effective June 15, 2017 and locations SW

-43 (Control), DW

-46, and DW-58 (Control) were added to the HNP REMP. Surface Water #43 and Drinking Water #58 are the control locations that replaced DWSW

-38 (AR #02093193). Indicator location #40 (Drinking Water/Surface Water - at NE Harnett Metro Water Treatment Plant Intake Building - Lillington in the SSE Sector) was changed to only a Surface Water per HNP ODCM Rev. 27 effective June 15, 2017 (AR #02093193). The collection frequency was changed for HNP Surface Water locations SW

-43 and SW-40 to monthly per HNP ODCM Rev. 27 Table 4.1 effective June 15, 2017. The frequency was listed as bimonthly previously to account for the dual usage (SW and DW) of locations #38 and #

40 (AR #02093193).

New indicator milk animals (goats) were identified within the five mile radius of HNP during the 2016 HNP Land Use Census conducted August 2 - 4, 2016 in the W sector at 2.82 miles. This sample location was added to the HNP ODCM with Revision 27 effective June 15, 2017. This will be Milk Indicator location #102 with semi-monthly sampling from late

-Spring to late

-Fall (seasonally available - April through October) (AR #02093193).

Appendix A - Page 3 Broadleaf Vegetation sample collection went to one mixed broadleaf vegetation (three types of broadleaf vegetation) per site instead of three separate types of broadleaf vegetation samples per site. This change was due to a lack of sufficient sample volume of each broadleaf vegetation type, which meets the HNP ODCM broadleaf vegetation sampling requirements.

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. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.), and then transferred to an appropriate counting geometry.

Low-level iodine analyses are performed by passing a designated sample aliquot throu gh a pre-measured amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk or 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.

Tritium analyses are performed by using low

-level environmental liquid scintillation analysis technique on a Perkin

-Elmer 2900TR liquid scintillation system or Perkin

-Elmer 3100TR 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.

Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate and analyzing 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 The tritium preparation procedure was modified during 2017 to align with ASTM method D4107

-08, Standard Test Method for Tritium in Drinking Water: Water and Environmental Technology. Volume 11.02. 2014 Edition. Tritium dark adaption times were also reduced (NCR # 02134015).

Appendix A - Page 4 IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE AND RADIOIODINE Airborne particulate and radioiodine samples at each of nine 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 and then the filters, by location, were composited to produce quarterly filter samples for gamma analysis. The continuous composite samples were collected from the locations listed below.

Location 1 = 2.6 miles N Location 2 = 1.4 miles NNE Location 4 = 3.1 miles NNE Location 5 = >12 miles WNW - Pittsboro (Control)

Location 26 = 4.7 miles S Location 47 = 3.4 miles SSW Location 63 = 0.6 miles SW Location 90 = 0.5 miles SSW Location 91 = 1.6 miles ENE

A.2 DRINKING WATER Drinking water/surface water location #38 was deleted from the HNP REMP per HNP ODCM Revision 27 effective June 15, 2017. The Cape Fear Plant has been decommissioned and the location returned to a green field. New drinking water locations were added at Lillington

(#46) and Sanford (#58). Drinking water/surface water location #40 (intake water) was replaced with new Lillington #46 drinking water (DW) and location #40 was changed to only a surface water location

. The new drinking water #58 located at the Sanford Water Treatment Plant intakes water upstream of Buckhorn Creek, 8.5 miles from the site in the SW sector. These drinking water samples are representative of the actual public drinking water.

Location #46 and #58 are the finished water of the water treatment plant system and representative of the public drinking water pathway (AR # 02093193).

The collection frequency changed to a monthly composite collection for DW

-46 and DW-58 per HNP ODCM Rev. 27 (effective June 15, 2017). Drinking water # 51 went to a biweekly composite collection which comprises the DW

-51 monthly composite sample.

Gross beta, tritium, and gamma analyses were performed on the monthly composites. The composites are collected from the locations listed below

.

Appendix A - Page 5 Location 38 = 6.2 miles WSW (Control)

(Removed from REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 40 = 17.2 miles SSE Lillington (Removed from REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 46 = 17.2 miles SSE Lillington - NE Harnett Metro Water Treatment Plant (Added to REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 51 = Water Treatment Building (on Site)

Location 58 = 8.5 miles SW (Control) - Sanford Water Treatment Plant (Added to REMP per HNP ODCM Rev. 27 Effective 6/15/17) A.3 SURFACE WATER Drinking water/surface water location #38 was deleted from the HNP REMP per HNP ODCM Revision 27 effective June 15, 2017. The Cape Fear Plant has been decommissioned and the location returned to a green field. Drinking water/surface water location #40 (intake water) was changed to only a surface water (SW) location. New surface water location w as added at Sanford (#43). The new surface water #43 located at the Sanford Water Treatment Plant intakes water upstream of Buckhorn Creek, 8.5 miles from the site in the SW sector. These surface water samples are representative of the actual public surface/raw water pathway (AR # 02093193). The collection frequency changed for surface water samples to monthly per HNP ODCM Rev. 27 (effective June 15, 2017)

Table 4.1. The frequency was previously listed as bimonthly to account for the dual usage of locations #38 and #40 (drinking water and surface water) samples; however, SW

-26 location remained a biweekly composite. Gross beta, tritium, and gamma analyses were performed on the monthly composites. The composites are collected from the locations listed below

. Location 26 = 4.7 miles S Location 38 = 6.2 miles WSW (Control)

(Removed from REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 40 = 17.2 miles SSE Lillington - NE Harnett Metro Water Treatment Plant (Amended in REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 43 = 8.5 miles SW (Control) - Sanford Water Treatment Plant (Added to REMP per HNP ODCM Rev. 27 Effective 6/15/17) A.4 GROUND WATER Grab samples were collected quarterly from ground water wells at eighteen locations. A gamma analysis and tritium analysis were performed on each sample. The samples were collected from the locations listed below.

Location 57 = 0.4 miles SSW Location 59 = 0.5 miles NNE Location 60 = 0.5 miles ESE Location 68 = 0.2 miles W Location 69 = 0.2 miles NNE

Semi-monthly grab samples were collected from the control location and the new indicator location May through mid

-November of 201 7. A gamma and low

-level Iodine

-131 analysis were performed on each sample. The grab samples were collected from the locations listed below.

Location 5 = Manco Dairy - >12 miles WNW (Control)

Location 102 = 2.82 miles W (Indicator)

A.6 BROADLEAF VEGETATION Monthly, three different species of broadleaf vegetation samples were collected when available during the growing season, May through October.

As of the 2017 broadleaf vegetation growing season (May through October), HNP broadleaf vegetation samples went to one mixed broadleaf vegetation (three types of broadleaf vegetation) per site instead of three separate types of broadleaf vegetation samples per site

. This change was due to a lack of sufficient sample volume of each broadleaf vegetation type.

A gamma analysis was performed on each sample. The samples were collected from the locations listed below.

Location 5 = >12 miles NNW - Pittsboro (Control)

Location 12 = 0.9 miles SSW Location 63 = 0.6 miles SW

Appendix A - Page 7 A.7 FOOD PRODUCTS Monthly samples, of three different types of food products, were collected when available during the growing season at o ne location. A gamma analysis was performed on each sample. The samples were collected from the location listed below. Location 97 = 19.1 miles NW - Granite Springs Farm (Control)

A.8 AQUATIC VEGETATION Annual samples were collected at each of the three locations. A gamma analysis was performed on each sample. The samples were collected from the locations listed below.

Location 26 = 4.7 miles S Location 41 = 3.8 miles S Location 61 = 2.5 miles E (Control)

A.9 FISH Semiannual samples of bottom feeders (catfish) and free swimmers (sunfish and largemouth bass) were collected at each of two locations. A gamma analysis was performed on the edible portions of each sample. The samples were collected from the locations listed below.

Location 44 = Site varies in Harris Lake Location 45 = Site varies in Cape Fear River above Buckhorn Dam (Control)

A.10 SHORELINE SEDIMENT Semiannual samples were collected at each of two locations. A gamma analysis was performed on each sample following the drying and removal of rocks and clams. The samples were collected from the locations listed below. Location 26 = 4.6 miles S Location 41 = 3.8 miles S

Appendix A - Page 8 A.11 BOTTOM SEDIMENT Semiannual samples were collected from the one location. A gamma analysis was performed on each sample following the drying; the removal of rocks, clams, etc.; and grinding. The samples were collected from the location listed below. Location 52 = 3.8 miles S

A.12 DIRECT GAMMA RADIATION (TLD)

Thermoluminescent dosimeters (TLD) were collected quarterly at forty-o ne locations during 2017

. 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 18 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 at a control location.

A.13 ANNUAL LAND USE CENSUS An Annual Land Use Census was conducted to identify within a distance of 8 kilometers (5.0 miles) 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 50 square meters or 500 square feet, producing broadleaf vegetables

• The Nearest Milk

-giving Animal (cow, goat, etc.)

• The Nearest Meat Animal (beef, hogs, etc.) w as only identified at the nearest garden or closer in each sector, and poultry and egg laying animals were not classified as meat animals for the 2017 census.

The census was conducted during the growing season from August 22 - 23 , 201 7. Results are shown in Table 3.12.3

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. Although quarterly composite samples are required, monthly composite samples are used to provide more frequent and sensitive analyses.

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

7. Tritium Lower Limit of Detection (LLD) is approximately 2.00E+2 pCi/L for samples that typically demonstrate activity less than the LLD.

8. Drinking Water 51 (DW

-51) has been included, as of 2009, in the Data Summary even though it does not meet the EPA (Environmental Protection Agency) definition of a public drinking water supply.

9. Gamma filter composite calendar reconciliation period, 2017 (NCR # 02174515).

SUMMARY

The Harris Nuclear Plant (HNP) is operated by Duke Energy Progress, LLC under a license granted by the Nuclear Regulatory Commission (NRC). Provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, Harris Nuclear Plant Technical Specifications, and the Harris Nuclear Plant Offsite Dose Calculation Manual (ODCM) establish the requirements of the Radiological Environmental Monitoring Program (REMP).

This report describes the HNP REMP and the program results for January 1, 201 7, through December 31, 2017.

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 Harris Nuclear Plant ODCM.

Required analyses were performed and detection capabilities were met for the collected samples required by the ODCM. One thousand four hundred and thirty-four samples were analyzed comprising 1,695 test results in order to compile data for the 2017 HNP Annual Radiological Environmental Operating Report (AREOR). Based on the annual HNP land use census, the current number of sampling sites for Harris Nuclear Plant is sufficient.

Concentrations observed in the environment in 201 7 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 all positively identified measurements attributed to plant operations were within the HNP ODCM regulatory limits.

The continued operation of HNP has not contributed measurable radiation or the presence of gamma radioactivity, with the exception of Harris Lake bottom sediment and the aquatic vegetation, in the environmental monitoring program. The Harris Lake Surface water samples and the 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 Harris Nuclear Plant consists of a pressurized water reactor with a net output of approximately 930 MWe (Megawatts electric). Commercial production was initiated on January 3, 1987. HNP is located in southwest Wake County, North Carolina. The site is along U.S. route 1 approximately sixteen (16) miles southwest of Raleigh, North Carolina and approximately fifteen (15) miles northeast of Sanford, North Carolina. The nearest community is New Hill, North Carolina, which is north of the site.

Harris Lake is adjacent to the plant itself and is the source of cooling tower makeup water. The lake was impounded during the construction of the Harris Plant. The lake is fed by Buckhorn

Creek and is approximately 4,400 acres in area. The main dam is approximately 4.7 miles south of the site. The primary discharges to Harris Lake from the plant are surface runoff, cooling tower blowdown, and radiological waste process systems.

Fishing, boating, and swimming are popular activities on Harris Lake and other nearby lakes. Duke Energy Progress, LLC encourages the recreational use of the lake, Harris Lake County Park, and the adjoining lands through a variety of agreements with state and local government.

Within a five

-mile radius, most of the land is wooded with only a few residences and limited agricultural activity. There are no residences on the plant site. The chief use of land is for production of timber and pulp fiber.

Within a ten

-mile radius, the area is considered rural with significant populations in Apex, Holly Springs, and Fuquay - Varina. Currently, these communities are experiencing significant growth.

Within a fifty

-mile radius, much of the land is used in agricultural production with significant crops including corn, soybeans, and tobacco. Livestock is also an important component with significant production in cattle, hogs, poultry, and dairy products.

Consumption of drinking water, food crops, and fish are sample media that are examples of ingestion pathways for exposure. Although the contribution to background radiation is small, Duke Energy Progress, LLC has established the Radiological Environmental Monitoring Program (REMP) to measure the exposure pathways to man.

An exposure pathway describes the source of the radiological exposure. The primary forms of 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, preoperational monitoring, and results of the land use surveys. A number of locations are selected as controls. Control locations are selected because they are unaffected by the operation of the plant. Figures 2.1-1, Section 2 - Page 2 2.1-2, 2.1-3, and 2.1-4 are maps depicting the HNP REMP sampling locations and the Thermoluminescent Dosimeter (TLD) monitoring locations. The location numbers shown on these maps correspond to those listed in Tables 2.1-A, 2.1-B, and 2.1-C. 2.2 SCOPE AND REQUIREMENTS OF THE REMP The Radiological Environmental Monitoring Program (REMP) was established in 1982 at the Harris Nuclear Plant (HNP). Radiation and radioactivity in various environmental media have been monitored for 3 5 years, including 5 years prior to commencing operation. Monitoring is also provided for control locations, which would not be impacted by operations of the HNP.

Using these control locations and data collected prior to operation allows comparison of data collected at locations near the HNP, 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.

This monitoring program is based on NRC guidance and is conducted in accordance with Operational Requirement 3.12.1 in the HNP Offsite Dose Calculation Manual (ODCM) and applicable procedures; 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. This program 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 HNP Offsite 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 3.12.3-1.

Participation in an interlaboratory comparison program is performed in fulfillment of HNP 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.

Section 2 - Page 3 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: x = N N i i x1 Where: x = estimate of the mean, i = individual sample, N = total number of samples with a net activity (or concentration), i = 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" LLDs for each sample medium and selected radionuclides are given in the ODCM and are listed in Table 2.2

-C.

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

Section 2 - Page 4 calculated using a sample background and may be thought of as an "actual" LLD for a particular sample measurement. Certain gross counting measurements display a calculated negative value, indicating background is greater than sample activity.

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 plant.

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 Chernobyl accident and the 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.

Section 3 - Page 1 3.0 INTERPRETATION OF RESULTS

The following section depicts and explains the review of the REMP results conducted during 2017 for the Harris Nuclear Plant (HNP) and fulfills the reporting requirements of Technical Specifications 6.9.1.3 and HNP ODCM E.3. Review of the 2017 REMP analysis results was performed to identify changes in environmental levels as a result of HNP operations. Sample data for 2017 was compared to preoperational and historical data.

Evaluation for significant trends was performed for radionuclides that are listed as required within the HNP ODCM. The radionuclides include: H

-3, Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, I-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 plant operation, but not required for reporting, are trended.

The HNP 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 HNP liquid effluents which contained the radionuclides.

Review of the 2017 data presented in this section supports the conclusion that there were no significant changes in environmental sample radionuclide concentrations of samples collected and analyzed from HNP and surrounding areas that were attributable to plant operations. Inspection of the data showed that radioactivity concentrations were as expected and all positively identified measurements attributed to plant operations were within HNP ODCM regulatory limits; thus presenting no significant impact to the environment or public health and safety.

A statistical summary of the HNP data for 2017 has been compiled and summarized in Appendix B along with any plant

-derived activity detected within the scope of the REMP. No detectable tritium activity was observed at Lillington, N.C., located 17 miles downstream on the Cape Fear River, which is the first public drinking water (ingestion pathway) location below the Harris Lake discharge spillway. No plant

-related gamma activity has been detected in fish collected from Harris Lake or in the water samples from Lillington, N.C. The Harris Lake bottom sediment and aquatic vegetation detected plant

-derived gamma activity, but pose no radiological dose to the general public via this pathway due to the fact that the bottom sediment is not easily accessible and aquatic vegetation is not an ingestion pathway. Bottom sediment samples are for long-term trends. 3.1 AIRBORNE RADIOIODINE AND PARTICULATES The 477 air cartridge/radioiodine (AC) samples from indicator and control stations had I

-131 concentrations less than the ODCM LLD of 7.00E-2 pCi/m 3. The air samplers Section 3 - Page 2 operated for a total of 99.93% availability for the 201 7 year. N o I-131 activity due to HNP operations has been detected in air samples collected from 1987 through 201 7 , which is the entire operating history of the plant.

However, I-131 was detected in air samples for a three

-week period following the Fukushima Dai

-ichi Nuclear Power Plant incident after the March 11, 2011, earthquake and tsunami (NCR # 0456564) and for a six-week period following the Chernobyl incident in April 1986. Refer to Table 3.1-1-B for the highest annual mean indicator location and control location I

-131 concentrations since 1999 to 2017.

For the period of January 1, 201 7, to December 31, 201 7, the gross beta activity was detectable in the airborne particulate (AP) samples, with acceptable runtime, from the eight indicator locations and the one control location. The 424 indicator samples had an average concentration of 2.02E-2 pCi/m 3 , a value slightly higher than the preoperational data of 2.00E

-2 pCi/m 3. Similar gross beta activities were observed at the control location in Pittsboro, which had an average concentration of 2.05E-2 pCi/m 3 in 53 control samples. Figure 3.1-1 and Table 3.1-1-A provide individual sample gross beta results for the highest annual mean indicator location and the control location concentrations since 1999 to 201 7 (refer to Appendix B). The two sample locations' results are similar in concentration and have negligible variance. The HNP 2010 gross beta result for the

highest annual mean indicator location in Figure 3.1

-1 and Table 3.1-1-A was elevated due to this location being a new air sampler location (end of July 2010) with less than half the annual samples (22 instead of 52). This new location is near a new gravel road which receives a lot of travel due to construction in the area.

No plant-related gamma activity was observed for any air particulate filters analyzed during 201

7. 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 2017 collection year.

No plant-related gamma activity was detected in quarterly composite filter samples from either the indicator or control locations during 201

7. HNP 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 DRINKING

WATER Low-level Iodine

-131 analysis of drinking water was not required during 201 7 since the dose calculated for the consumption of the water was not greater than 1 mrem per year in any supported program. This dose was calculated monthly during 201 7 to ensure that low-level Iodine

-131 analysis of drinking water samples was not required

. The water samplers operated for a total of 99.

47% availability for the 201 7 year. Refer to Appendix C or Appendix D for deviations and unavailable samples in 201 7 collection year, if applicable.

The average annual gross beta concentrations at the indicator and control locations were

3.61E+0 pCi/L and 4.44E+0 pCi/L, respectively. The preoperational average was 4.00E+0 pCi/L. These concentrations are attributed to the natural environment and are not attributed to plant operations. Figure 3.2-1 and Table 3.2-2 show individual gross beta results for the highest annual mean gross beta concentration for indicator and control locations since 1999 to 2017.

Analyses for gamma

-emitting radionuclides from plant operations indicated concentrations were less than the lower limit of detection for drinking water. Table 2.2-C contains ODCM LLD values for gamma-emitting radionuclides in drinking water.

Tritium concentrations in the Lillington Municipal Water Supply samples (DW/SW-40) were less than the ODCM LLD (2000 pCi/L) and the administrative limit (200 pCi/L)

Section 3 - Page 5 (see Appendix B, Footnote 7). The annual average tritium concentration for the Water Treatment Building sample on site (DW-51) was 4.

02E+3 pCi/L, with a minimum and maximum value of 3.03E+3 pCi/L and 5.84E+3 pCi/L, respectively. Figure 3.2

-2 and Table 3.2-2 display the highest annual mean indicator and control location concentrations for tritium since 1999 to 201

7. Prior to 2009, DW

-51 was not classified as a public drinking water source nor as a HNP REMP drinking water indicator location. In 2009, DW-51 was added to the HNP REMP as a drinking water indicator sample and it was classified as a public water source; however, it is not a community drinking water source.

The concentrations of man

-made gamma

-emitters were less than their respective lower limits of detection (see Table 2.2-C). The annual average tritium concentration in Harris Lake at the Spillway was 5.

98E+3 pCi/L with minimum and maximum values of 4.42E+3 pCi/L and 9.12E+3 pCi/L, respectively. The average Harris Lake Spillway (SW

-26) tritium concentration is comparable to the previous tritium average of 5.68E+3 pCi/L in 201

6. This concentration remains well below the tritium regulatory limits. Figure 3.3-2 and Table 3.3-2 display the tritium results for the highest annual mean concentrations for indicator and control locations since 1999 to 2017.

Average gross beta concentrations at the indicator and control locations were 3.9 7E+0 pCi/L and 4.05E+0 pCi/L, respectively, in 201 7, indicating no contribution from plant operations.

The measured ground water gamma and tritium concentrations were below the required HNP ODCM Table 4.12

-1 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.

HNP administratively established a ground water tritium analysis LLD of approximately 2 00 pCi/L, which is well below the requirements specified in the HNP ODCM.

The ground water tritium analysis shows the presence of tritium, ranging from 1.99E+2 pCi/Liter to 1.17E+3 pCi/Liter in 201 7; however, the results are well below the EPA reportable drinking water limit (20,000 pCi/Liter) and non

-drinking water limit (30,000 pCi/Liter). The ground water wells, located on site at HNP, are monitoring wells and are not a water supply for drinking or irrigation. Therefore, there is no radiological dose via this pathway.

3.5 MILK/BROADLEAF VEGETATION During 201 7, as in the past years with the exception of the 1986 Chernobyl incident and the 2011 Japan earthquake and tsunami which triggered the Fukushima Dai

-ichi Nuclear Power Plant incident (N CR #0458543), no I-131 activity w as detected in the control milk sample. This control milk location is located greater than 12 miles WNW from the plant, thus in an area to be out of the influence of the plant. Gamma analyses revealed no detectable radioactivity from plant operations. Natural gamma activity is consistently identified in each control milk sample along with other natural ly occurring nuclides.

From 2010 to 2013, a small local goat dairy, Humbug Farm Milk # 96, provided goat milk samples during the spring and summer months. In 2013, Humbug Farm ceased operation (NCR # 0604191). ODCM Rev. 26 removed this location from the Radiological Environmental Monitoring Program. Maple Knoll Dairy was removed form the program in 1997. New milk animals (goats) were identified within the five mile radius of HNP during the 2016 HNP Land Use Census conducted August 2 - 4, 2016 in the W sector at 2.82 miles. The family has indicated that they could possibly participate by providing goat milk samples for analysis from late

-Spring to late

-Fall. This will be Milk Indicator location # 102. The sampling started semi

-monthly in November 2016 and ran through middle of December 2016. This sample location was added to the HNP ODCM Rev. 27 effective June 15, 2017

. Fifteen indicator milk samples were collected in 2017.

In lieu of the monthly milk samples, per HNP ODCM Table 3.12-1, indicator broadleaf vegetation samples were collected in both the SW and SSW sectors. Broadleaf sampling is conducted to simulate dose to an individual via the milk pathway for compliance purposes. Broadleaf vegetation sampling is accomplished by collecting monthly, three different species of samples, when available during the growing season (May through October), at two locations at the site boundary (two indicator locations of the highest predicted annual average ground level D/Q) and at the control location (BL

-5 in the Section 3 - Page 10 NNW sector at greater than 12 miles).

As of the 2017 broadleaf vegetation growing season (May through October), HNP broadleaf vegetation samples went to one mixed broadleaf vegetation (three types of broadleaf vegetation) per site instead of three separate types of broadleaf vegetation samples per site. This change was due to a lack of sufficient sample volume of each broadleaf vegetation type, which meets the HNP ODCM broadleaf vegetation sampling requirements. The gamma analyses on the broadleaf vegetation did not detect any plant

-related radioactivity in any of the six control and twelve indicator broadleaf vegetation samples (mixed broadleaf vegetation) in 201

7. Refer to Appendix C or Appendix D for deviations and unavailable samples in the 201 7 collection year, if applicable.

3.6 FOOD PRODUCTS None of the gardens identified during past or present annual Land Use Census are irrigated by water in which liquid plant wastes have been discharged; therefore, food product collection is not required. There is no indicator location for this media type and sampling at a control location is maintained for historical integrity. In November 2014, a new food product control location #97 at the Granite Springs Farm (19.1 miles in NW sector) was officially introduced to the REMP to be sampled along with control location #5. However, during the 2016 growing season, no food crops from location #5 were collected due to the lack of availability (NCR # 0727501). Location # 5 food product or food crop was deleted from the HNP ODCM with Revision 26 effective 9/23/16.

In addition to milk sampling (or broadleaf vegetation sampling), a food product sampling program was maintained. Various crops were collected during the growing season(s),

which continued year round. The species selected were primarily broad

-leaf vegetables, which are most sensitive to direct fallout of airborne radioactive particulates. Gamma analyses of the food products detected no plant

-related activity in any of the thirty-six samples from control location #97 collected in 201

7. Refer to Appendix C or Appendix D for deviations and unavailable samples in the 2017 collection year.

3.7 AQUATIC

VEGETATION The 201 7 data shows that there were fo ur aquatic vegetation indicator samples and tw o control samples collected from Harris Lake, which are sampled annually. The aquatic vegetation samples (Lyngbya and Hydrilla) from Harris Lake are not consumed by humans, thus pose no radiological dose to the general public by the ingestion pathway.

Gamma analyses of the aquatic vegetation detected plant

-related activity in the four indicator samples and the two control samples collected during 201

7. The 2017 data shows the average concentration at the indicator and control locations , where Co-60 was 1.45E+1 pCi/kg wet and less than LLD respectively and Cs

-137 was 8.99E+0 pCi/kg wet and 9.51E+0 pCi/kg wet respectively (NCR # 02162038). No long-term trends have been readily observed in these samples.

Section 3 - Page 11 3.8 FISH Analyses for gamma

-emitting radionuclides in four samples of bottom

-feeding species (catfish) and in eight samples of free

-swimming species (sunfish and largemouth bass) from the indicator and control locations revealed no detectable activity for 201 7, other than naturally occurring nuclides. This is consistent with the data for 1989-2016. During the Chernobyl period, Cs

-134 and Cs

-137 were detected in both control and indicator fish samples. 3.9 SHORELINE SEDIMENT Shoreline sediment samples were collected semiannually in 201 7 from opposite the discharge structure and near the main dam. Gamma analyses of the shoreline sediments detected natural activity in the samples collected during 201

7. No long

-term trends are readily observed in these samples.

3.10 BOTTOM SEDIMENT During 201 7, a total of two bottom sediment samples were analyzed from the indicator location. There is no control bottom sediment sample.

The 201 7 data shows Co-58 (4.01E+1 pCi/kg dry), Co-60 (2.14E+2 pCi/kg dry), and Cs-137 (8.35E+1 pCi/kg dry) activity in the indicator samples, which are sampled semiannually. The bottom sediment sample from Harris Lake poses no radiological dose to the general public via this pathway due to the fact that it is not easily accessible (i.e.

bottom sediment is approximately forty to sixty feet underwater). These samples are for long-term trends for liquid effluents.

TLDs are collected and analyzed quarterly. Since the inception of the HNP REMP, the regional population has moved closer to the plant and TLD locations 3 and 50 are the new Special Interest locations per HNP ODCM Revision 26 effective 9/23/16.

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 14.

4 mR/Std. Qtr. and 1 5.9 mR/Std. Qtr. respectively. The highest indicator location was 2.0 miles NW of the plant and its average was 17.9 mR/Std. Qtr. The differences among these locations are attributed to variations in soils, local geology, and are not the result of plant operations.

S ix TLDs were missing from different designated locations during the 2017 calendar year. No trends were identified and all TLD surveillance requirements were met for 2017 (see Appendix C).

Comparison of the average annual TLD exposure within approximately 2 miles (inner ring) of the plant with that at approximately 5 miles (outer ring) and the control for 1999 to 2017 is presented in Figure 3.11-1 and Table 3.11-1.

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. This change in environmental TLDs for the REMP indicates a step change in activity as mentioned in NCR # 01982479 between the Panasonic TLD readings prior to 2014 and the Harshaw TLD readings from 2014 to present. There are three factors that can be attributed to the step increase that was observed: (1) the annealing method levels employed were lower for the Panasonic TLDs, (2) transit control subtraction differences, and (3) the calculation/method of fade correction (fixed fade control -

vs - actual in field TLDs). Data accrual began in 2016 for enhanced analytical methods which will be evaluated for future implementation when sufficient data is available. The new methods will improve data transparency and interpretation.

A TLD intercomparison program is conducted as part of the quality assurance program. Results of this program are included in Section 4.7.

Section 3 - Page 15 3.12 LAND USE CENSUS The 201 7 HNP Annual Land Use Census was conducted August 22 through 23 , 201 7, as required by the HNP ODCM 4.12.2. Table 3.12.3

-1 summarizes the comparison between the 201 6 and 201 7 census results. A map indicating identified locations is shown in Figure 3.12.3

-1. During the 201 7 census, no irrigated gardens were identified within fiv e miles (8 kilometers) of HNP.

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 completed during the growing season each year. 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 crops that may have radioactive materials deposited on them, incorporated radioactive materials from the soil or atmosphere. Another pathway is through drinking milk or eating goat cheese 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.

Section 3 - Page 16 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]):

The nearest resident The nearest garden of greater than 500 square feet, producing broadleaf vegetables The nearest milk 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 2016 and 2017 results of the survey for the nearest resident, garden, milk and meat animals in each sector are compared in Table 3.12.3-1.

The nearest resident, garden, and meat animal in each sector remained the same from 2016 to 2017, except for the changes indicated in Table 3.12.3-1. In 2017, no resident, garden, meat or milk animal were located within 5 miles of the plant for the South (S) sector. Milk goats were found in the N and W sectors in 201

7.

--- Indicates no occurrences within the 5 mile radius (1) Meat animal was only identified at the nearest garden or closer in each sector.

Poultry and egg laying animals were not classified as meat animals for the 2017 census.

(2) Goat Milk - Milk is used to feed goat kids, make a small quantity of cheese, and to make soap for personal use. Owner said they can now supply enough milk to participate in the HNP REMP.

This dairy is not required due to HNP already having a dairy within 5 km (3.11 miles) and the dose being <1.0 mRem/year.

(3) Goat Milk - Milk is used to feed goat kids during the breeding months and the family consumes what is left. The milk that is not suitable for consumption is given to someone to make soap. This location participates in the REMP and milk is collected for 4 - 6 consecutive months per year (Late

-Spring to Late

-Fall months).

Section 4 - Page 2 4.5 DUKE ENERGY INTERLABORATORY COMPARISON PROGRAM In 201 7 Duke Energy Environmental Laboratory (EnRad) participated in an interlaboratory program to satisfy Radiological Environmental Monitoring Program requirements in Duke Energy nuclear plant Offsite Dose Calculation Manuals and Selected Licensee Commitments Manuals, as applicable. The EnRad organization, in 2017, elected to voluntarily withdraw its North Carolina State Drinking Water Certification with the North Carolina Department of Health and Human Services, State Laboratory of Public Health. It was determined that there was no longer a business case for maintaining this certification (NCR # 02093309). Samples requiring this certification are sent to General Engineering Laboratories, LLC (GEL), which maintains the necessary certifications to meet regulatory commitments for drinking water.

EnRad Laboratory participated in an interlaboratory program with Eckert & Ziegler Analytics (EZA) in 2017. EZA results were evaluated against the NRC Inspection Manual Procedure 84750 (IP 84750) acceptance criteria stated in EnRad Procedure 515, Cross Check Program Administration. All regulatory requirements continue to be met by the EZA Cross Check Program.

4.5.1 DUKE ENERGY INTERLABORATORY PROGRAM EnRad Laboratories made the determination in 2017 to discontinue its participation in the Duke Energy Fleet Scientific Services (FSS) Interlaboratory Program, as EnRad already maintains a sufficient cross check program through EZA. Historically, Duke Energy FSS has maintained its own Interlaboratory Program supporting the Duke Energy fleet. At EnRad, this has been a supplement to EnRad's participation in the EZA Cross Check Program. In 2017, FSS determined that shifting business needs had reduced the need for the FSS Interlaboratory Program and the majority of the Interlaboratory Program has been discontinued.

4.5.2 ECKERT

& ZIEGLER ANALYTICS CROSS CHECK PROGRAM EnRad Laboratories participated in the Eckert & Ziegler Analytics (EZA) Cross Check Program during 201

7. Cross check samples including mixed gamma in liquid, mixed gamma in vegetation, low

-level I-131 in liquid, mixed gamma air filters (single and composites), mixed gamma and I-131 air cartridges, strontium in water, gross alpha and beta in water, gross alpha and beta in filters, and tritium in water were analyzed at various times of the year. A summary of the EnRad Laboratory program results for 2017 is documented in Table 4.0-A.

Interlaboratory cross check samples from EZA were received and analyzed in all four quarters of 2017. Table 4.0-A lists the performance for specific samples. Eighty-seven nuclide results were reported to EZA of which eighty-six (98.9%) met the acceptance criteria based on IP 84750.

One EZA cross check nuclide result did exhibit a high bias and EnRad proactively initiate d an NCR to investigate th is bias.

Section 4 - Page 3 In the second quarter of 2017, a mixed gamma in filter cross check (E11890) yielded a disagreement on only the Zinc 65 nuclide value (ratio to the known of 130%). An overall high bias was noted across all other nuclides, primarily in the high energy range. NCR # 02138003 was written to investigate and document the failure. It was determined that the geometry used for gamma filter counting contained compounding biases, leading to consistently high results in the upper energy range. Following the implementation of a new filter geometry, an equivalent filter cross check (E12011) was analyzed in the fourth quarter of 2017.

The cross check passed with reduced biases, and a Zinc-65 nuclide value of 111%

of the known.

4.5.3 ERA PROFICIENCY TESTING EnRad Laboratories made the determination in 2017 to discontinue its participation in the Environmental Resource Associates (ERA) Proficiency Testing program, as this program's participation was solely for the purpose of maintaining EnRad's North Carolina State Drinking Water Certification requirements (NCR # 02093309).

4.6 STATE

OF NORTH CAROLINA INTERCOMPARISON PROGRAM EnRad Laboratories routinely participates with the North Carolina Department of Health and Human Services in an intercomparison program. EnRad Laboratories sends Harris Nuclear Plant Radiological Environmental Monitoring Program air, drinking water, surface water, milk, fish, food products, ground water, and shoreline sediment samples to the North Carolina Department of Health and Human Services, Division of Public Health for intercomparison analysis. 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 2017 Nuclear Technology Services Intercomparison Report is documented in Table 4.0-B. 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. During first quarter of 201 7 an environmental external TLD cross check failed and NCR # 021 47847 was written to document the failure of the four individual TLDs; however, the overall result fell within both the Duke Energy and Nuclear Technology Services, Inc.

acceptance criteria. To prevent recurrence, the four TLDs were pulled and visually inspected for abnormalities in the elements and overall integrity of the TLDs and no abnormalities were found. The four TLDs were checked per procedure and Section 4 - Page 4 TLDs # 53 3830 and 103 632 were both removed from service. Complete documentation of any evaluation will be available and provided to the NRC upon request. 4.7.2 INTERNAL CROSS CHECK (DUKE ENERGY)

Radiation Dosimetry and Records participates in a quarterly TLD internal comparison 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. A summary of the 201 7

Internal Cross Check (Duke Energy) Program is documented in Table 4.0-B.

APPENDIX A ENVIRONMENTAL SAMPLING

& ANALYSIS PROCEDURES

Appendix A - Page 2 APPENDIX A ENVIRONMENTAL SAMPLING AND ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of environmental media at the Harris Nuclear Plant (HNP) was required to ensure compliance with provisions of the Nuclear Regulatory Commission's Regulatory Guide 4.8, Harris Nuclear Plant Technical Specifications, and the Harris Nuclear Plant Offsite Dose Calculation Manual (ODCM). Analytical procedures were employed to ensure that the ODCM detection capabilities were achieved.

Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, Environmental Water Resources Group, and General Engineering Laboratories, LLC (vendor lab).

This appendix describes the environmental sampling frequencies and analysis procedures by media type.

I. CHANGE OF SAMPLING PROCEDURES Control location

1. 038 (Drinking Water/Surface Water - at Cape Fear Steam Electric Plant water intake structure in the WSW sector) was deleted from the HNP REMP per

HNP ODCM Rev. 27 effective June 15, 2017 and locations SW

-43 (Control), DW

-46, and DW-58 (Control) were added to the HNP REMP. Surface Water #43 and Drinking Water #58 are the control locations that replaced DWSW

-38 (AR #02093193). Indicator location #40 (Drinking Water/Surface Water - at NE Harnett Metro Water Treatment Plant Intake Building - Lillington in the SSE Sector) was changed to only a Surface Water per HNP ODCM Rev. 27 effective June 15, 2017 (AR #02093193). The collection frequency was changed for HNP Surface Water locations SW

-43 and SW-40 to monthly per HNP ODCM Rev. 27 Table 4.1 effective June 15, 2017. The frequency was listed as bimonthly previously to account for the dual usage (SW and DW) of locations #38 and #

40 (AR #02093193).

New indicator milk animals (goats) were identified within the five mile radius of HNP during the 2016 HNP Land Use Census conducted August 2 - 4, 2016 in the W sector at 2.82 miles. This sample location was added to the HNP ODCM with Revision 27 effective June 15, 2017. This will be Milk Indicator location #102 with semi-monthly sampling from late

-Spring to late

-Fall (seasonally available - April through October) (AR #02093193).

Appendix A - Page 3 Broadleaf Vegetation sample collection went to one mixed broadleaf vegetation (three types of broadleaf vegetation) per site instead of three separate types of broadleaf vegetation samples per site. This change was due to a lack of sufficient sample volume of each broadleaf vegetation type, which meets the HNP ODCM broadleaf vegetation sampling requirements.

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. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.), and then transferred to an appropriate counting geometry.

Low-level iodine analyses are performed by passing a designated sample aliquot throu gh a pre-measured amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk or 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.

Tritium analyses are performed by using low

-level environmental liquid scintillation analysis technique on a Perkin

-Elmer 2900TR liquid scintillation system or Perkin

-Elmer 3100TR 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.

Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate and analyzing 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 The tritium preparation procedure was modified during 2017 to align with ASTM method D4107

-08, Standard Test Method for Tritium in Drinking Water: Water and Environmental Technology. Volume 11.02. 2014 Edition. Tritium dark adaption times were also reduced (NCR # 02134015).

Appendix A - Page 4 IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE AND RADIOIODINE Airborne particulate and radioiodine samples at each of nine 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 and then the filters, by location, were composited to produce quarterly filter samples for gamma analysis. The continuous composite samples were collected from the locations listed below.

Location 1 = 2.6 miles N Location 2 = 1.4 miles NNE Location 4 = 3.1 miles NNE Location 5 = >12 miles WNW - Pittsboro (Control)

Location 26 = 4.7 miles S Location 47 = 3.4 miles SSW Location 63 = 0.6 miles SW Location 90 = 0.5 miles SSW Location 91 = 1.6 miles ENE

A.2 DRINKING WATER Drinking water/surface water location #38 was deleted from the HNP REMP per HNP ODCM Revision 27 effective June 15, 2017. The Cape Fear Plant has been decommissioned and the location returned to a green field. New drinking water locations were added at Lillington

(#46) and Sanford (#58). Drinking water/surface water location #40 (intake water) was replaced with new Lillington #46 drinking water (DW) and location #40 was changed to only a surface water location

. The new drinking water #58 located at the Sanford Water Treatment Plant intakes water upstream of Buckhorn Creek, 8.5 miles from the site in the SW sector. These drinking water samples are representative of the actual public drinking water.

Location #46 and #58 are the finished water of the water treatment plant system and representative of the public drinking water pathway (AR # 02093193).

The collection frequency changed to a monthly composite collection for DW

-46 and DW-58 per HNP ODCM Rev. 27 (effective June 15, 2017). Drinking water # 51 went to a biweekly composite collection which comprises the DW

-51 monthly composite sample.

Gross beta, tritium, and gamma analyses were performed on the monthly composites. The composites are collected from the locations listed below

.

Location 58 = 8.5 miles SW (Control) - Sanford Water Treatment Plant (Added to REMP per HNP ODCM Rev. 27 Effective 6/15/17) A.3 SURFACE WATER Drinking water/surface water location #38 was deleted from the HNP REMP per HNP ODCM Revision 27 effective June 15, 2017. The Cape Fear Plant has been decommissioned and the location returned to a green field. Drinking water/surface water location #40 (intake water) was changed to only a surface water (SW) location. New surface water location w as added at Sanford (#43). The new surface water #43 located at the Sanford Water Treatment Plant intakes water upstream of Buckhorn Creek, 8.5 miles from the site in the SW sector. These surface water samples are representative of the actual public surface/raw water pathway (AR # 02093193). The collection frequency changed for surface water samples to monthly per HNP ODCM Rev. 27 (effective June 15, 2017)

Table 4.1. The frequency was previously listed as bimonthly to account for the dual usage of locations #38 and #40 (drinking water and surface water) samples; however, SW

-26 location remained a biweekly composite. Gross beta, tritium, and gamma analyses were performed on the monthly composites. The composites are collected from the locations listed below

. Location 26 = 4.7 miles S Location 38 = 6.2 miles WSW (Control)

(Removed from REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 40 = 17.2 miles SSE Lillington - NE Harnett Metro Water Treatment Plant (Amended in REMP per HNP ODCM Rev. 27 Effective 6/15/17) Location 43 = 8.5 miles SW (Control) - Sanford Water Treatment Plant (Added to REMP per HNP ODCM Rev. 27 Effective 6/15/17) A.4 GROUND WATER Grab samples were collected quarterly from ground water wells at eighteen locations. A gamma analysis and tritium analysis were performed on each sample. The samples were collected from the locations listed below.

Semi-monthly grab samples were collected from the control location and the new indicator location May through mid

-November of 201 7. A gamma and low

-level Iodine

-131 analysis were performed on each sample. The grab samples were collected from the locations listed below.

Location 5 = Manco Dairy - >12 miles WNW (Control)

Location 102 = 2.82 miles W (Indicator)

A.6 BROADLEAF VEGETATION Monthly, three different species of broadleaf vegetation samples were collected when available during the growing season, May through October.

As of the 2017 broadleaf vegetation growing season (May through October), HNP broadleaf vegetation samples went to one mixed broadleaf vegetation (three types of broadleaf vegetation) per site instead of three separate types of broadleaf vegetation samples per site

. This change was due to a lack of sufficient sample volume of each broadleaf vegetation type.

A gamma analysis was performed on each sample. The samples were collected from the locations listed below.

Location 5 = >12 miles NNW - Pittsboro (Control)

Location 12 = 0.9 miles SSW Location 63 = 0.6 miles SW

Appendix A - Page 7 A.7 FOOD PRODUCTS Monthly samples, of three different types of food products, were collected when available during the growing season at o ne location.

Thermoluminescent dosimeters (TLD) were collected quarterly at forty-o ne locations during 2017

. 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 18 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 at a control location.

A.13 ANNUAL LAND USE CENSUS An Annual Land Use Census was conducted to identify within a distance of 8 kilometers (5.0 miles) 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 50 square meters or 500 square feet, producing broadleaf vegetables

• The Nearest Milk

-giving Animal (cow, goat, etc.)

• The Nearest Meat Animal (beef, hogs, etc.) w as only identified at the nearest garden or closer in each sector, and poultry and egg laying animals were not classified as meat animals for the 2017 census.

The census was conducted during the growing season from August 22 - 23 , 201 7. Results are shown in Table 3.12.3

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. Although quarterly composite samples are required, monthly composite samples are used to provide more frequent and sensitive analyses.

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

7. Tritium Lower Limit of Detection (LLD) is approximately 2.00E+2 pCi/L for samples that typically demonstrate activity less than the LLD.

8. Drinking Water 51 (DW

-51) has been included, as of 2009, in the Data Summary even though it does not meet the EPA (Environmental Protection Agency) definition of a public drinking water supply.

9. Gamma filter composite calendar reconciliation period, 2017 (NCR # 02174515).
