EXECUTIVE
SUMMARY
The Harris Nuclear Plant (HNP) is operated by Carolina Power & Light Company, doing business as Progress Energy Carolinas, Inc., under a license granted by the Nuclear Regulatory Commission. 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 provides the results of the Radiological Environmental Monitoring program from January 1, 2010, through December 31, 2010.
The Radiological Environmental Monitoring Program (REMP) was established in 1982.
Radiation and radioactivity in various environmental media have been monitored for more than 25 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. Radiation levels show no significant change from pre-operational radiation levels.
Monitoring results for environmental media are summarized as follows:
> Air-monitoring results are slightly higher than the concentrations of radioactivity from pre-operation monitoring. These observations are also consistent with past operational data and control data.
Milk and broadleaf vegetation monitoring results are similar to all the past years where no 1-131 concentrations were detected. Broadleaf vegetation is in lieu of indicator milk samples, due to no milk-producing animal within five miles of the plant. An indicator milk-producing animal within five miles of the plant was introduced into the monitoring program mid-September 2010.
)" Terrestrial vegetation includes various crops collected during a growing season and results indicate no detectable radioactivity.
Aquatic organism monitoring includes fish and aquatic vegetation. The fish and aquatic vegetation results indicate no detectable radioactivity.
Surface (and drinking) water results indicate no detectable gamma radionuclides including 1-131, except for the 1-131 noted in Interpretations and Conclusions section/
Drinking and Surface Water, which is performed by an 1-131 separation analysis.
Surface water (non-drinking water) results from the Harris Lake spillway show the presence of tritium, which is attributed to plant operation, but is well below the EPA reportable non-drinking water limit (30,000 pCi/Liter) and drinking water limit (20,000 pCi/Liter). Refer to the Interpretations and Conclusions section/ Surface Water.
1
External radiation dose showed no measurable change from pre-operational data.
The continued operation of the HNP has not contributed measurable radiation or the presence of gamma radioactivity, with the exception of Harris Lake bottom sediment, in the environmental monitoring program. The Harris Lake Surface water samples revealed tritium concentrations that are well within the applicable regulatory limits.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM PURPOSE AND REQUIREMENTS FOR THE RADIOLOGICAL MONITORING PROGRAM The operation of a nuclear generating station may increase background radiation by a small fraction. It is important to measure these emissions of radioactivity and radiation to assess their impact on the surrounding populations. The purpose of the radiological monitoring program (surveillances) is to measure accumulation of radioactivity in the environments, to determine whether this radioactivity is the result of operation of HNP, and to assess the potential dose to the off-site population based on the cumulative measurements of radioactivity of plant origin.
Radiological monitoring programs provide an additional verification of the radiological controls of nuclear generating stations.
The HNP Radiological Environmental Monitoring Program was established in 1982 and has continued to collect samples and evaluate them for over 25 years.
Requirements are established for the Radiological Environmental Monitoring Program with the following:
Technical Specifications
> Off-Site Dose Calculation Manual (ODCM)
Various procedures Additional guidance regarding the Radiological Environmental Monitoring Program may be found in the following:
> NRC Regulatory Guide 1.109 NRC Regulatory Guide 4.13
> NRC Regulatory Guide 4.15 3
General Site Description The Harris Nuclear Plant consists of a pressurized water reactor with a net output of approximately 900 MWe r P PA (Megawatts electric). Commercial production was initiated on January 3, 1987.
7 NP is located in southwest Wake County, North Carolina. The site is C.0 along U.S. route 1 approximately sixteen (16) miles southwest of Raleigh, North jf Carolina and is displayed on the map of -& R#
central North Carolina (Figure 1). The site is also approximately fifteen (15) miles northeast of Sanford, North Carolina. The nearest community is New Hill, which is north of the site.
Harris Lake is adjacent to the plant itself and is the source of cooling tower Ia makeup water. The lake was impounded ,, ," r-' V during the construction of Harris Plant.
The lake is fed by Buckhorn Creek and is Figure 1: Location of Harris Nuclear Plant approximately 4,000 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.
Carolina Power & Light Company, doing business as Progress Energy Carolinas, Inc.,
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 the 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.
4
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.
RADIOLOGICAL MONITORING PROGRAM QUALITY ASSURANCE A required component of the REMP is the Quality Assurance Program. The standards for the quality assurance program are established in the NRC Regulatory Guide 4.15, "Quality Assurance for Radiological Monitoring Programs." The purpose of the quality assurance program is "(1) to identify deficiencies in the sampling and measurement processes to those responsible for these operations so that corrective action can be taken, and (2) to obtain some measure of confidence in the results of the monitoring programs in order to assure the regulatory agencies and the public that the results are valid."(NRC Regulatory Guide 4.15 B Pg. 4.15-2)
This provides the opportunity to implement corrective actions that address possible deficiencies.
Examples of the activities of the quality assurance program include:
>- regular review of sample collection and records
> regular review of laboratory procedures and methods
> participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program, which provides an independent assessment of the quality of laboratory results
> the use of known concentrations of radioactivity in test samples by the laboratory to ensure consistent quality results on an ongoing basis 5
RADIOLOGICAL MONITORING PROGRAM GENERAL DESCRIPTION Although the contribution to background radiation is small, Carolina Power & Light Company doing business as Progress Energy Carolinas, Inc. has established this program to measure the exposure pathways to man. An exposure pathway describes the source of the radiological exposure. The primary forms of 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. Below in Table 1 is a list of the media used to assess each of these pathways.
Table 1 Media Used to Assess Exposure Pathways to Man Pathway of Exposure to Man Media Sampled External Dose Thermoluminescent Dosimetry (TLD)
Shoreline Sediment Ingestion Aquatic Vegetation Drinking Water Food Crops Fish Ground Water Milk Broadleaf Vegetation (when Milk samples are unavailable)
Surface Water Inhalation Air Samples (Particulate & Radioiodine)
Sampling Locations 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 stations are selected because they are unaffected by the operation of the plant. Sample locations may be seen in Figures 2a, 2b, 3a, 3b, and 3c. A description of each sample location may be found in Tables 2 and 3.

SUMMARY
OF RADIOLOGICAL MONITORING PROGRAM This report presents the results of the Radiological Environmental Monitoring Program conducted during 2010 for the Harris Nuclear Plant and fulfills the reporting requirements of Technical Specifications 6.9.1.3 and ODCM E.3. The program was conducted in accordance with Operational Requirement 3.12.1 in the Off-Site Dose Calculation Manual (ODCM), and applicable procedures.
Approximately 1327 total samples of 14 different media types from approximately 1090 indicator samples were compared to approximately 237 control samples. Control stations are locations that are unaffected by plant operations. In approximately 99 percent of the indicator samples there was no difference from the activities observed in the corresponding control samples.
Radioactivity in environmental samples attributed to plant operations in 2010 for which there is a potential dose pathway to the public is as follows:
Environmental Radionuclide Location of Activity and Occurrence Maximum Media w/Highest Annual Individual Dose Mean (mrem/yr)
Surface Water H-3 Harris Lake 3,830 pCiIL (12/12) No ingestion pathway.
No dose calculated.
Fish H-3 Harris Lake See above. 0.008 Assumes H-3 equilibrium between lake water and Total Body fish tissue.
The radiological environmental data indicates that HNP operations in 2010 had no significant impact on the environment or public health and safety.
A statistical summary of all the data for 2010 has been compiled and summarized in Table 4.
The plant-derived activity detected within the scope of the Radiological Environmental Monitoring Program can be seen in the Data Summary Table 4 for 2010. 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 (SD) and the Aquatic Vegetation (AV) pose no radiological dose to the general public via this pathway due to the fact that the SD is not easily accessible and the AV is not an ingestion pathway. These samples are for long-term trends.

FOOTNOTES TO TABLE 4
- 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.
- 2. Mean and range are based on detectable measurements only. The fractions of all samples with detectable activities at specific locations are indicated in parentheses.
- 3. Missing samples are discussed in Missed Surveillances.
- 4. Although quarterly composite samples are required, monthly composite samples are used to provide more frequent and sensitive analyses.
- 5. TLD exposure is reported in milliroentgen (mR) per 90-day period (quarter) beginning in 1995. This is the exposure standard used to compare data to the Nuclear Regulatory Commission (NRC).
- 6. Tritium Lower Limit of Detection (LLD) is approximately 2.50E+2 pCi/L for samples that typically demonstrate activity less than the LLD. The LLD was lowered at the request of Carolina Power & Light Company doing business as Progress Energy Carolinas, Inc. in order to maintain comparable LLD and result values with the NC Division of Radiation Protection (NCDRP) laboratory. Other samples that typically exhibit activity greater than the LLD have a tritium Lower Limit of Detection (LLD) of L.OE+3 pCi/L.
- 7. 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.

INTERPRETATIONS AND CONCLUSIONS Air Monitoring All 378 air cartridge (AC) samples from indicator and control stations had 1-131 concentrations less than the typical LLD of 5.59E-2 pCi/mr3. The air samplers operated for a total of 99.5%
availability for the 2010 year. 1-131 was detected in air samples for a six-week period following the Chernobyl incident in April 1986. With this exception, no 1-131 has been detected in air samples collected from 1987 through 2010, which is the entire operating history of the plant.
For the period of January 1, 2010, to December 31, 2010, the gross beta activity was detectable in all airborne particulate (AP) samples, with acceptable runtime, from the eight indicator locations.
The 326 indicator samples had an average concentration of 2.40E-2 pCi/m3 , a value slightly higher than the preoperational data of 2.OOE-2 pCi/m 3 . Similar gross beta activities were observed at the control location in Pittsboro, which had an average concentration of 2.12E-2 pCi/m3 in 52 control samples. Figures 4 through 11 provide a graphic representation of the gross beta activity at the indicator locations compared to the control location for the year 2010. AP samples that exhibit an elevated gross beta activity typically have a gamma isotopic analysis done and the results indicate all natural gamma activity. No plant-related gamma activity was observed for any air particulates during 2010. These concentrations are typical of the natural environment and are not attributed to plant operations.
No plant-related gamma activity was detected in quarterly composite filter samples from either the indicator or control locations. Typical LLDs for air particulates are contained in Table 5.
Drinking Water The 26 drinking water samples collected at the Lillington Municipal water supply, the 26 water treatment building samples at the Harris Plant, and the control samples collected from the Cape Fear River above the Buckhorn Dam contained less than detectable 1-131 activity (< 1.OE+0 pCi/L) during 2010, except for seven control (DW/SW-38) samples (see chart). As indicated in the chart, the control composite water sample taken from the Cape Fear River, at the Cape Fear Plant, indicated small concentrations of 1-131 ranging from 4.95E-1 pCi/Liter to 8.49E-1 pCi/Liter for the stated sample dates. This location is upstream of the discharge of Harris Lake.
22
Downstream of Harris Lake discharge at the Cape Fear River at the Lillington Water Treatment Plant (SW/DW-40), one out of seven corresponding samples detected 1-131 during the collection period indicated in the chart; otherwise, no 1-131 was detected. Therefore, the presence of 1-131 would not be attributable to plant operations, along with the information that during the timeframes indicated water was not going over the spillway at the Harris Lake Dam. For the sample period of March 22, 2010, to April 5, 2010, a similar sample was taken from downstream at the Harris Lake Spillway discharge (SW-26) with no detectable 1-131 detected (see chart).
This indicates that the 1-131 detected at the control location is from a source other than the plant's effluents as discussed in a previous investigation (NCR # 189683). Note that data from sample collection period December 28, 2010, to January 10, 2011, will be reported and discussed in the HNP 2011 Radiological Environmental Operating Report (REOR) (NCR # 441977). It has typically been the experience for all the 1-131 drinking water samples to contain less than detectable activity (< 1.0E+0 pCi/L) for the preoperational and operational period with the exception of 1986 when the fallout from Chernobyl was detected. The water samplers operated for a total of 99.8% availability for the 2010 year. Refer to the Missed Surveillance Section on the missed drinking/surface water samples (NCR # 435923) in 2010 collection year.

The average annual gross beta concentrations at the indicator and control locations were similar with concentrations of 4.24E+0 pCi/L and 5.09E+0 pCi/L, respectively. The preoperational average was 4.OOE+0 pCi/L. These concentrations are attributed to the natural environment and are not attributed to plant operations. Figure 12 provides graphic representation of the drinking water gross beta activity during 2010 for Location 40 (Lillington) and Location 38 (control at Cape Fear).
Analyses for gamma-emitting radionuclides from plant operations indicated all concentrations were less than the lower limit of detection for drinking water. Table 5 contains typical LLD values for gamma-emitting radionuclides in drinking water.
Tritium concentrations in the Lillington Municipal Water Supply samples were less than the lower limit of detection (approximately 2.50E+2 pCi/L) (see Footnotes to Table 4, Footnote 6).
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 2010, other than naturally occurring nuclides. This is consistent with the data for 1989-2009. During the Chernobyl period, Cs-134 and Cs-137 were detected in both control and indicator samples.
Fish are assumed to be in equilibrium with the tritium concentration in the lake. The total body/organ dose to the maximum exposed individual due to tritium was calculated using Regulatory Guide 1. 109, Rev. 1, October 1977, Equation A-i, to be 0.008 mrem/year.
Equation A- I Raipj - Cip Uap Daipj where as:
Raipj = total body dose in mrem/yr of H-3 Cip = concentration of nuclide (H-3) in pCi/kg = pCi/L Uap = maximum exposed individual's consumption (Reg. Guide 1.109 Table E-5) 24
Daipj ingestion dose factor for total body/organ of individual in Uap in mrem/pCi (Reg. Guide 1.109 Table E- 11, E-12, or E-13)
The Total Body/Organ dose is as follows:
Child Teenager Adult Consumption of fish kg/yr 6.9 16 21 Dose (Total Body/Organ) mrem/yr 0.005 0.006 0.008 The total body dose and organ dose, due to tritium in the fish, (ingestion dose factor - Reg. Guide 1.109 Table E- 11, E-12, and E-13) for the maximum exposed individuals consuming 6.9 kg fish/yr. for a child, 16 kg fish/yr. for a teenager, and 21 kg fish/yr. for an adult are 0.005, 0.006, and 0.008 mrem/year respectively.
Milk/Broadleaf Vegetation During 2010, as in all past years with the exception of the Chemobyl period, no 1-131 concentrations were detected in control milk samples. Gamma analyses revealed no detectable radioactivity from plant operations. The only detectable gamma activity consistently identified in each control milk sample was potassium-40 (K-40). This is a natural occurring nuclide in any organic material. The K-40 concentrations in the milk control samples range from 1.59E+3 pCi/L to 2.03E+3 pCi/L. Other natural occurring nuclides are identified in some of the control milk samples. In mid-September of 2010, the Humbug Farm (Goat milk indicator MK located in the ESE sector) was added to the HNP Environmental Monitoring Program. The K-40 concentrations in the goat milk indicator samples range from 2.1 1E+3 pCi/Liter to 2.48E+3 pCi/Liter. Other natural occurring nuclides are identified in the goat milk.
In May of 1997, the Maple Knoll Dairy (indicator MK located in the SSE sector) ceased operations. In lieu of the monthly milk samples, per HNP ODCM Table 3.12-1, broadleaf vegetation samples were collected in both the South (S) and SSW sectors.
Broadleaf sampling is conducted since only one milk animal location is available within a radius of approximately five miles of the plant and is used to simulate dose to an individual via the milk 25
pathway for compliance purposes. Broadleaf vegetation sampling is accomplished by collecting monthly, three different species of samples, when available, 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 NNW sector at greater than 12 miles). The gamma analyses on the broadleaf vegetation did not detect any plant-related radioactivity in any of the broadleaf vegetation (Fig Leaf, Maple, Sweetgum, and Wax Myrtle) in 2010. Refer to the Missed Surveillance Section for the missed (unavailable) surveillances (NCR # 389806, 396382, 435924, and 438363).
Surface Water Surface water samples were collected (weekly) and analyzed (bi-weekly) for 1-131. Water samples collected contained less than detectable 1-131 activity (< 1.OE+O pCi/L) during 2010, except for seven control (DW/SW-38) samples (see chart in Drinking Water Section). As indicated in the chart, the control composite water samples taken from the Cape Fear River, at the Cape Fear Plant, indicated small concentrations of 1-131 ranging from 4.95E-1 pCi/Liter to 8.49E-1 pCi/Liter for the stated sample dates. This location is upstream of the discharge of Harris Lake. Downstream of Harris Lake discharge at the Cape Fear River at the Lillington Water Treatment Plant (SW/DW-40), one out of seven corresponding samples detected 1-131 during the collection period indicated in the chart; otherwise, no 1-131 was detected. Therefore, the presence of 1-131 would not be attributable to plant operations, along with the information that during the timeframes indicated water was not going over the spillway at the Harris Lake Dam. For the sample period of March 22, 2010, to April 5, 2010, a similar sample was taken from downstream at the Harris Lake Spillway discharge (SW-26) with no detectable 1-131 detected (see chart in Drinking Water Section). This indicates that the 1-131 detected at the control location is from a source other than the plant's effluents as discussed in a previous investigation (NCR # 189683). Note that data from sample collection period December 28, 2010, to January 10, 2011, will be reported and discussed in the HNP 2011 REOR (NCR #
441977). It has typically been the experience for all the 1-131 drinking water samples to contain less than detectable activity (< 1.OE+0 pCi/L) for the preoperational and operational period with the exception of 1986 when the fallout from Chernobyl was detected. The water samplers operated for a total of 99.8% availability for the 2010 year. Refer to the Missed Surveillance Section on the missed drinking/surface water samples (NCR # 435923) in 2010 collection year.

Average gross beta concentrations at the indicator and control locations were 5.15E+0 pCi/L and 5.09E+0 pCi/L, respectively, in 2010, indicating no adverse influence from plant operations (See Figure 13).
Surface water samples were analyzed for gamma and tritium radioactivity. All concentrations of man-made gamma-emitters were less than their respective lower limits of detection (see Table 5).
The annual average tritium concentration in Harris Lake at the Spillway was 3.83E+3 pCi/L with minimum and maximum values of 2.50E+3 pCi/L and 5.46E+3 pCi/L, respectively (see Figure 14). The average Harris Lake Spillway tritium concentration showed a decrease in tritium compared to the annual average of 5.50E+3 pCi/L in 2009. This concentration remains well below regulatory limits. The tritium liquid release program is optimized by releasing liquid effluents during periods of high rainfall to minimize the impact of the tritium concentration in the lake. The decrease in average tritium concentration from 2009 to 2010 is partially due to the tritium release program and the rainfall in 2010.
Ground Water Ground water samples are collected on site at HNP for gamma and tritium analysis. The measured concentrations of the gamma analyses indicated concentrations below their required Lower Limits of Detection (LLD) as specified in the Harris Plant ODCM (docket No. STN 400) in Table 4.12-1 titled "Detection Capabilities For Environmental Sample Analysis Lower Limit of Detection (LLD)" for the year 2010.
The measured tritium concentrations were below the required HNP ODCM Table 4.12-1 LLD for environmental samples. These 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 250 pCi/L, which is well below the requirements specified in the FHNP ODCM.
The ground water tritium analysis determined that there was no detectable tritium concentration present based on the LLD specified in the HNP ODCM for 2010, except for low levels of tritium activity for GW-76 ranging from 284 pCi/Liter to 448 pCi/Liter. The ground water wells, located 27
on site at HNP, are all abandoned wells and are not a water supply for drinking or irrigation.
Therefore, there is no radiological dose via this pathway.
Shoreline Sediment Shoreline sediment samples were collected semiannually in 2010 from (1) opposite the discharge structure and (2) near the main dam. Gamma analyses of the shoreline sediments detected all natural activity in the samples collected during 2010. No long-term trends are readily observed in these samples.
Bottom Sediment The 2010 data shows Cobalt (Co)-60 (3.48E-1 pCi/gm dry to 1.02E+0 pCi/gm dry) and Cesium (Cs)-137 (1.49E-1 pCi/gm dry to 2.97E-1 pCi/gm dry) activity in the indicator sample, which is 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 under water). These samples are for long-term trends for liquid effluents.
Food Crops 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. Crops sampled in 2010 included collards, cucumbers, eggplants, okra, and tomatoes. Gamma analyses of the food crops detected no plant-related activity in nine (9) samples from indicator locations and eight (8) samples from control locations collected in 2010.
28
Aquatic Vepetation The 2010 data shows that there were three aquatic vegetation indicator samples collected from Harris Lake, which are sampled annually. The aquatic vegetation samples from Harris Lake pose no radiological dose to the general public by the ingestion pathway. Gamma analyses of the aquatic vegetation detected no plant-related activity in the three indicator samples collected during 2010. No long-term trends are readily observed in these samples.
External Radiation Exposure 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 11.9 mR and 14.7 mR, respectively. The highest indicator location was 8.7 miles NE of the plant (Apex at Population Center) and its average was 15.8 mR/qtr. The differences among these locations are attributed to variations in soils, local geology, and are not the result of plant operations.
Comparison of the quarterly TLD exposure within approximately 2 miles (inner ring) of the plant with that at approximately 5 miles (outer ring) is presented in Figure 15. These data illustrate that the quarterly inner ring TLD exposures are slightly less than the quarterly outer ring TLD exposures (differences range from less than 0.01 mR to 0.40 mR). TLDs # 16, # 17, and # 18 were deleted from the 2010 HNP Environmental Monitoring Program in the 4 th Quarter of 2010 and were replaced with TLDs # 93, # 94, and # 95 in the 3 rd Quarter of 2010 for safer sample locations (NCR # 393038). Upon validating the TLDs locations using a GPS unit (NCR #
392755), it was determined that TLD # 6 and TLD # 49 sectors were listed incorrectly in the HNP ODCM and thus in the Annual HNP REOR (NCR # 393030). The correct sectors for both TLD # 6 and # 49 are now listed in the HNP ODCM and the current HNP REOR.

However, this sample will still be counted and the data reported; whereas a "missed sample" will have no data reported. There were no missed samples in 2010 from the established air samplers.
The air samplers operated for a total of 99.5% availability in 2010.
Missed Samples:
" None in 2010 from established air samplers
" The new locations (APAC-63, 90, & 91) were put into service the end of July 2010. In May 2009, due to weather changes, the meteorology in ODCM Revision 20 was updated using the five year average meteorology (2003 through 2007). The meteorology previously used in the ODCM for Revision 0 through Revision 19 used the average ten year meteorology from 1976 through 1987. This change in the meteorology produced a change from previous ODCM revisions in two of the three highest D/Q sectors for collecting air samples (air cartridges and air particulates). Therefore, from May 2009 to July 2010, two of the three highest D/Q sectors were not monitored. Since July 2010, air samples and cartridges have been obtained from those locations. The 2009 air samplers' locations are based on the pre-Revision 20 ODCM meteorology. The installation of the air samplers was tracked in the plant's corrective action program (NCR # 309988).

Food Crops Food crops are no longer required to be collected as of July 27, 2006, Revision 18 of the HNP ODCM; therefore, any food crops collected is above and beyond requirements, but will appear in the current year's data report (NCR # 141151). Sampling of gardens goes above and beyond regulatory guidance since none of the gardens identified during the annual Land-Use Census are irrigated by water in which liquid plant wastes have been discharged. Therefore, the absence of food crops from these locations does not constitute a failure to monitor a pathway.
The farmers and individuals at each garden location sampled during 2010 did not plant or produce three (3) different kinds of food crops in 2010. This was mostly due to seasonal unavailability, lack of sufficient quantity planted or lack of a variety of crops planted, and crops being too small to harvest at the time of collection.
Drinking / Surface Water DW/SW-38 (November 15 - November 29, 2010) had missed surveillances (NCR # 435923).
The drinking/surface water environmental sample (at Cape Fear Plant) for collection period November 15 through November 29, 2010, was found not working on November 22, 2010 due to a tripped breaker. Numerous attempts were made to reset the breaker by qualified personnel to no success. It was determined to be a malfunctioning breaker. A temporary power source was established and power restored to the water sampler. A work order was submitted by plant electrician to correct the problem. It was estimated that the sampler was out of service for approximately 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
Milk / Broad Leaf Ve2etation If milk sampling cannot be performed, then 3 different kinds of broad leaf vegetation nearest each of two different offsite locations of highest predicted annual average ground level D/Q shall be sampled. The new indicator milk sample that was introduced to the HNP Environmental Monitoring Program in mid-September (Humbug Farm - goat milk) was not available in December of 2010 (NCR # 438362). Broadleaf vegetation samples were not available for 31
sampling due to seasonal unavailability during January, February, March, April, November, and December of 2010 (NCR # 389806, 396382, 435924, and 438363).
TLDs Two TLD samples, out of a possible 179 TLD samples (indicator and control locations), were missing during 2010.
TLD # 27 First Quarter 2010 TLD # 27 was missing in the field. The power pole that the TLD was located on appeared to have been replaced. The area was searched, but the TLD could not be located (NCR # 392254).
TLD # 34 Second Quarter 2010 TLD # 34 was missing in the field. The area was searched, but the TLD could not be located (NCR # 408643).

ANALYTICAL PROCEDURES Gross Beta Gross beta radioactivity measurements are made utilizing a Tennelec Low-Background Alpha/Beta Counting System. The LLD for air particulates is approximately 5. IE-3 pCi/mi3 for HNP samples. Air particulate samples are mounted in 2-inch stainless steel planchets and counted directly.
Gross beta activity in drinking and surface waters is determined by evaporating 1 liter of the sample and counting a planchet on a Tennelec Low-Background Alpha/Beta Counting System for 50 minutes. Typical LLD for gross beta is 1.2E+0 pCi/L.
,Tritium Liquid samples requiring tritium analysis are treated with a small amount of sodium hydroxide, potassium permanganate crystals, and then distilled. Five milliliters of the distillate are mixed with thirteen milliliters of liquid scintillation cocktail and counted in a liquid scintillation counter. Samples are counted for 315 minutes with a LLD of approximately 2.50E+2 pCi/L.
Iodine-131 Iodine-131 airborne concentrations are analyzed by the intrinsic germanium (Ge) spectrometry systems. The cartridges are placed on the detector, and each charcoal cartridge is counted individually with an LLD of 5.59E-2 pCi/m 3.
Iodine-131 in milk and drinking water is determined by an instrumental method. Analysis involves passing 4 liters of sample over an anion exchange resin and direct gamma analysis of the resin with an intrinsic Ge detector. The LLD using the Ge detector is approximately 1.OE+0 pCi/L using 25,000-second and 40,000-second count times respectively.
33
Gamma Spectrometry Gamma samples are analyzed by the intrinsic germanium detectors with thin aluminum windows housed in steel and lead shields. The analyzer system is the Canberra APEX Gamma Spectroscopy System. Table 5 summarizes LLD values derived from using the instrument with the worst sensitivity, typical sample volumes, typical count times, typical worst background count, and worst case on decay (from collection to counting).
Air particulate filter quarterly composites are placed in a Petri dish and analyzed directly for 1,500 seconds.
Liquid samples, milk and water, are transferred to Marinelli beakers and analyzed by gamma counting. One-liter ground water samples are gamma scanned directly in a 1-Liter Marinelli beaker for 16,000 seconds and the SW/DW samples for 73,000 seconds. One-liter milk samples are analyzed in a 1-liter Marinelli beaker for 12,600 seconds.
Shoreline and bottom sediments are dried, weighed, and then analyzed in a 1-liter Marinelli beaker for 840 seconds (> 1000 grams, dry) or 1,380 seconds (< 1000 grams, dry).
Aquatic vegetation and broadleaf vegetation samples are weighed as sampled and analyzed in a Marinelli beaker for 7,500 seconds. If any food crop samples are collected they will be handled like the aquatic and broadleaf vegetation samples.
Fish samples are prepared by stuffing small raw, edible portions of the fish in a 1-liter Marinelli beaker for gamma analysis using a count time of 1,500 seconds.
Thermoluminescent Dosimetry Each area monitoring station includes a TLD packet which is a polyethylene bag containing three calcium sulfate phosphors contained in a Panasonic UD-814 badge. The TLD is light tight and the bag is weather-resistant.
Dosimeters are machine annealed before field placement. Following exposure in the field, each dosimeter is read utilizing a Panasonic TLD reader. This instrument integrates the light photons emitted from traps as the dosimeter is heated. Calibration is calculated using dosimeters 34
irradiated to known doses for each set of dosimeters measured. Prior to the measurement of each dosimeter, the instrument is checked through use of an internal constant light source as a secondary standard.
The exposure reported is corrected for exposure received in transit and during storage through the use of control dosimeters.
Interlaboratory Comparison Program The Radiochemistry Laboratory at the Harris Energy & Environmental Center in New Hill, North Carolina, provides radioanalytical services for Carolina Power & Light Company's, doing business as Progress Energy Carolinas, Inc., nuclear plant radiological environmental surveillance programs. In fulfillment of ODCM Operational Requirements, the laboratory is a participant in the Eckert & Ziegler Analytics Environmental Cross-Check Program and uses its performance in this program as a major determinant of the accuracy and precision of its analytical results.
During 2010, 88 analyses were completed on 21 samples representing seven major environmental media (i.e., water, milk, air filters, air filters composite, soil, air cartridges, and simulated vegetation). Data on the known activities, the uncertainties, and the ratios to the known for the 88 analyses have been received from Eckert & Ziegler Analytics. The results were compared to the criteria established in the NRC Inspection Manual (Procedure 84750) for Radioactive Waste Treatment, Effluent, and Environmental monitoring (see below results).
All of the 88 analyses were within the acceptance criteria. During 2010, 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 (NCR # 400312, and 419981). Complete documentation of any evaluation will be available and provided to the NRC upon request.

LAND-USE CENSUS PURPOSE OF THE 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 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 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.
Methodology The following must be identified within the five (5) mile 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 42
The primary methods are visual inspection from the roadside within the five (5) mile radius and personal contact with the individuals.
2010 Land-Use Census Results The 2009 and 2010 results of the survey for the nearest resident, garden, milk and meat animals in each sector are compared in Table 6.
The nearest resident in each sector remained the same from 2009 to 2010. No gardens were located within 5 miles of the plant for the NE, ENE, SE, SSE, S, WNW, and NW sectors. All the gardens located in 2010 were the same as the gardens located in 2009, except for where the 2010 survey did not locate any gardens in the ENE, SE, and NW sectors. A closer garden was located in the W sector during the 2010 survey. All meat animals located in 2010 were the same as 2009, except for the E sector, where no meat animal was located. No meat animals were found in the NNE, NE, E, SSE, S, SSW, W, and WNW sectors in 2010. Milk goats were found in the ESE sector and have been incorporated into the HNP environmental monitoring sample program as of September 20, 2010. Harris Lake County Park was included in the 2010 survey, even though there are not yet permanent residents on site. There are plans in the future for rangers and a campground. Although technically just outside the 5-mile radius, the resident in the S sector has again been included in the data because of the historical prevailing winds.
