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, 2007 through December 31, 2007.

The Radiological Environmental Monitoring program was established in 1982. Radiation and radioactivity in various environmental media have been monitored for more than 20 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 similar or less than the concentrations of radioactivity from pre-operation monitoring. These observations are also consistent with past operational 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.

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 results indicate no detectable radioactivity; whereas, the aquatic vegetation indicates detectable radioactivity in four out of five samples. Refer to the Interpretations and Conclusions section/ Aquatic Vegetation.

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 Harris Lake 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.

I

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 and aquatic vegetation, 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 monitoring program was established in 1982 and has continued to collect samples and evaluate them for over 20 years.

Requirements are established for the radiological monitoring program with the following:

Technical Specifications Off-Site Dose Calculation Manual (ODCM)

Various procedures Additional guidance regarding the radiological 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 9W

, BO C, rs "b

output of approximately 900 MWe hy 1

(Mega Watts electric). Commercial h.s A.

production was initiated on January 3, 521

/03 1987. HNP is located in southwest Wake 70 County, North Carolina. The site is cm/

341 Ei along U.S. route 1 approximately sixteen I"\\b (16) miles southwest of Raleigh, North eshi=fle 1.

Carolina and is displayed on the map of 2 (

central North Carolina (Figure 1). The

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 blow down, 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 I is a list of the media used to assess each of these pathways.

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, 3, 3a, and 3b. 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 2007 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 1136 total samples of 13 different media types from approximately 901 indicator samples were compared to approximately 235 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 2007 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 5,260 pCi/L (12/12)

No ingestion pathway.

No dose calculated.

Fish H-3 Harris Lake See above.

0.012 Assumes H-3 equilibrium between lake water and Total Body fish tissue.

The radiological environmental data indicates that HNP operations in 2007 had no significant impact on the environment or public health and safety.

A statistical summary of all the data for 2007 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 2007. 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 3.50 E+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 1.0 E+3 pCi/L.

7.

Drinking Water 51 (DW-51) is not included because it does not meet the EPA (Environmental Protection Agency) definition of a public drinking water supply.

INTERPRETATIONS AND CONCLUSIONS Air Monitorin2 All 318 air cartridge (AC) samples from indicator and control stations had 1-131 concentrations less than the typical LLD of 6.3E-2 pCi/m3. The air samplers operated for a total of 99.9%

availability for the 2007 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 2007, which is the entire operating history of the plant.

For the period of January 1, 2007 to December 31, 2007; the gross beta activity was detectable in all airborne particulate (AP) samples, with acceptable runtime, from the five indicator locations.

The 265 indicator samples had an average concentration of 2.20E-2 pCi/m 3, a value similar to the preoperational data of 2.OOE-2 pCi/m3.

Similar gross beta activities were observed at the control location in Pittsboro, which had an average concentration of 2.29E-2 pCi/mi3 in 53 control samples. Figures 4 through 8 provide a graphic representation of the gross beta activity at the indicator locations compared to the control location for the year 2007. AP samples that exhibit an elevated gross beta activity typically have a gamma isotopic analysis done and the results indicate all naturalgamma activity. Air particulate sample 47 (AP-47) was out of trend low for sample collection time of 07/10/07 as compared to the other five AP locations for gross beta (NCR # 241602).

A gamma analysis was performed on the AP filter in question and it indicated all natural gamma activity. No plant-related gamma activity was observed for any air particulates during 2007. 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.

Drinkini! Water The 26 drinking water samples collected at the Lillington Municipal water supply and the 26 control samples collected from the Cape Fear River above the Buckhorn Dam contained less 22

than detectable 1-131 activity (< l.0E+0 pCi/L) during 2007, except for one indicator sample (DW/SW-40) during the 04/30/07 composite period (NCR # 233020).

During the time in question, there was no discharge of Harris Lake water (SW-26) to the Cape Fear River and no detectable 1-131 in Harris Lake water (SW-26); therefore, the presence of 1-131 would not be attributable to plant operations. This indicates that the 1-131 at the indicator location is from a source other than the plant's effluents as discussed in a previous investigation (NCR # 189683).

This has typically been the experience 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 98.8% availability for the 2007 year. 'Refer to the Missed Surveillance Section on the missed drinking/surface water samples (NCR # 225713, 230759, and 245296).

The average annual gross beta concentrations at the indicator and control locations were similar in concentrations of 5.01E+0 pCi/L and 5.67E+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 9 provides graphic representation of the drinking water gross beta activity during 2007 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 (3.50 E+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 2007, other than naturally occurring nuclides. This is consistent with the data for 1989-2006. During the Chernobyl period, Cs-134 and Cs-137 were detected in both control and indicator samples.

23

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 0.012 mremlyear.

Equation A-I Raipj = Cip Uap Daipj where as:

Raipj Cip Uap Daipj

=

total body dose in mrem/yr of H-3 concentration of nuclide (H-3) in pCi/kg = pCi/L

=

maximum exposed individual's consumption (Reg. Guide 1.109 Table E-5) 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:

Consumption of fish kg/yr Dose (Total Body/Organ) mrem/yr The total body dose and organ dose, due to tritium in the fish, (ingestion dose factor - Reg.

Guide 1.109 Table E-11, E-1 2, and E-1 3) 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 0.007, 0.009, and 0.012 mrem/year respectively.

24

Milk/Broadleaf Vegetation During 2007, as in all past years with the exception of the Chernobyl 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 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 1.10E+3 pCi/L-1.38E+3 pCi/L. Other natural occurring nuclides are identified in some of the milk samples.

In May of 1997, the Maple Knoll Dairy (indicator MK located in the SSE sector) ceased operations. In lieu of the semimonthly 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 no milk animals are available within a radius of approximately five miles of the plant and is used 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, 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 highest predicted annual average ground level D/Q (ODCM Table A-I through A-4) was at the site boundary in both the South sector at 1.36 miles (BL-65) and SSW sector at 1.33 miles (BL-66). The control location (BL-5) was introduced into the environmental sampling program for HNP in January 2004.

The gamma analyses on the broadleaf vegetation did not detect any plant-related radioactivity in any of the broadleaf vegetation (Dogwood, Fig Leaf, Maple, and Sweetgum) in 2007, except for Cs-137 on a broadleaf vegetation (Maple) sample for a single occurrence of 3.77E-2 pCi/gm for BL-66 in May of 2007.

Refer to the Missed Surveillance Section for the missed (unavailable) surveillances (NCR # 227419, 230699, 233912, 242934, 247228, and 250953).

Surface Water Surface water samples were collected (weekly) and analyzed (bi-weekly) for 1-131.

Water samples collected during 2007 contained less than detectable 1-131 activity (< 1.OE+0 pCi/L),

except for one SW/DW-40 sample during the 04/30/07 composite period (NCR # 233020).

25

During the time in question, there was no discharge of Harris Lake water (SW-26) to the Cape Fear River and no detectable 1-131 in Harris Lake water (SW-26); therefore, the presence of I-131 would not be attributable to plant operations. This indicates that the 1-131 at the indicator location is from a source other than the plant's effluents as discussed in a previous investigation (NCR # 189683). The water samplers operated for a total of 98.8% availability for the 2007 year. Refer to the Missed Surveillance Section on the missed drinking/surface water samples (NCR # 225713, 229890, 230759, and 245296).

Average gross beta concentrations at the indicator and control locations were 4.70E+0 pCi/L and 5.67E+0 pCi/L, respectively, in 2007, indicating no adverse influence from plant operations (See Figure 10).

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 was 5.26E+3 pCi/L with minimum and maximum values of 3.36E+3 pCi/L and 8.55E+3 pCi/L, respectively (see Figure 11).

The average Harris Lake tritium concentration showed an increase in tritium compared to the annual average of 4.73E+3 pCi/L in 2006. 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 increase in average tritium concentration from 2006 to 2007 is partially due to the drought conditions.

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 2007.

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 26

water pathway and 3000 pCi/L if no drinking water pathway exists.

HNP administratively established a ground water tritium analysis LLD of 350 pCi/L, which is well below the requirements specified in the HNP 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 2007. The ground water monitoring program was expanded in 2007 by the addition of new ground water wells to increase the total of ground water wells being monitored to eight. The ground water wells, located 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 2007 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 2007. No long-term trends are readily observed in these samples.

Bottom Sediment The 2007 data shows Cobalt (Co)-60 (4.00E 7.83E-1 pCi/gm dry) and Cesium (Cs)-137 (2.1 IE-I - 2.19E-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 27

sensitive to direct fallout of airborne radioactive particulates. Crops sampled in 2007 included broccoli, cabbage, collards, cucumbers, egg plants, lettuce, mustard greens, squash, and tomatoes. Gamma analyses of the food crops detected no plant-related activity in 16 samples from indicator locations and 12 samples from control locations collected in 2007.

Aquatic Vegetation The 2007 data shows that there were five 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 Cobalt (Co)-58 (1.95E 3.34E-2 pCi/gm wet) in four out of the five indicator samples collected during 2007 (see Table 4) (NCR # 257734). 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 11.5 mR and 14.3 mR, respectively. The highest indicator location was 9.2 miles ESE of the plant (Fuquay Varina at the old CP&L office) and its average was 14.9 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 12. These data illustrate that the quarterly inner ring TLD exposures are slightly less than the quarterly outer ring TLD exposures (differences range from 0.17 mR to 0.39 mR).

MISSED SURVEILLANCES Air Cartridge and Air Particulates Any REMP weekly air samples (Air Cartridge - AC or Air Particulate - AP) that exceed 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months of down time in a surveillance period will be reported as a "missed surveillance".

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 or missed surveillances in 2007. The air samplers operated for a total of 99.9% availability in 2007.

Missed Samples:

None in 2007 Missed Surveillances:

None in 2007 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 2007 did not plant or produce three (3) different kinds of food crops in 2007.

This was mostly due to seasonal unavailability, lack of sufficient quantity planted or lack of a variety of crops planted, drought conditions, and crops being too small to harvest at the time of collection.

29

Drinking / Surface Water SW-26 (March 12, 2007) had missed surveillances (NCR # 225713).

The surface water environmental sample (Spillway at Harris Lake) for March 12, 2007 had a low volume with no specific cause. While sufficient volume was collected during the two week collection period to support analyses; sample aliquots were not able to be obtained each day as required by the ODCM.

DW/SW-40 (March 12, 2007) had a missed sample (NCR # 225713).

The drinking/surface water environmental sample (Lillington - Cape Fear) for March 12, 2007 was a missed sample (no sample was available) due to the water level being noticeably lower than normal.

While sufficient volume was collected during the two week collection period to support analyses; sample aliquots were not able to be obtained each day as required by the ODCM.

SW-26 (April 16, 2007) had missed surveillances (NCR # 229890).

The surface water environmental sample (Spillway at Harris Lake) for April 16, 2007 was out of service due to a loss of power that occurred during a high wind condition for approximately 21 hours2.430556e-4 days 0.00583 hours 3.472222e-5 weeks 7.9905e-6 months .

The sampler did not restart when the power came back on.

While sufficient volume was collected during the two week collection period to support analyses; sample aliquots were not able to be obtained each day as required by the ODCM.

DW/SW-38 (April 23, 2007) had missed surveillances (NCR # 230759).

The drinking/surface water environmental sample (at Cape Fear) for April 23, 2007 was found with the sample container full and the sampler automatically shut off on high sample container level 28 hours3.240741e-4 days 0.00778 hours 4.62963e-5 weeks 1.0654e-5 months prior to the end of the collection period. The apparent cause was a rise in river level due to recent heavy rains. The composite sampler was adjusted slightly to reduce the incremental volumes being collected. While sufficient volume was collected during the two week collection period to support analyses; sample aliquots were not able to be obtained each day as required by the ODCM.

30

DW/SW-40 (September 4, 2007) had missed surveillances (NCR # 245296).

The drinking/surface water environmental sample (Lillington - Cape Fear) for September 4, 2007 was found with the sample container full and the sampler automatically shut off on high sample container level 17 hours1.967593e-4 days 0.00472 hours 2.810847e-5 weeks 6.4685e-6 months prior to the end of the collection period. The apparent cause was improper equipment operation. The composite sampler was adjusted slightly to reduce the incremental volumes being collected. While sufficient volume was collected during the two week collection period to support analyses; sample aliquots were not able to be obtained each day as required by the ODCM.

Milk / Broad Leaf Vepgetation 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. Broadleaf vegetation samples were not available for sampling due to seasonal unavailability during January, February, March, April, May, August, September, October, November, and December of 2007 (NCR # 227419, 230699, 233912, 242934, 247228, and 250953).

TLDs Three TLD samples, out of a possible 176 TLD samples (indicator and control locations), were missing during 2007.

TLD # 20 First Quarter 2007 TLD # 20 was missing in the field. The area was searched, but the TLD could not be located. The cage and TLD were replaced on an existing fence post (NCR #

228405).

TLD # 36 First Quarter 2007 TLD # 36 was missing in the field due to the removal of the pole which was due to construction.

A new cage and TLD were placed on a nearby tree (NCR #

228405).

31

TLD # 19 Third Quarter 2007 TLD # 19 was missing in the field. The area was searched, but the TLD could not be located (NCR # 249311).

32

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 4.4E-3 pCi/m 3 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 I 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 200 minutes with an approximate LLD of 3.50E+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 6.3E-2 pCi/m3.

Iodine-131 in milk and drinking water is determined by an instrumental method.

Analysis involves passing 4 liters 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 Nuclear 9900 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 7,000 seconds.

Liquid samples, except milk, are boiled down to a small volume, transferred to a Poly Bottle (PB-50 beaker) and analyzed by gamma counting the groundwater samples for 8,400 seconds and the DW/SW samples for 40,000 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 1,500 seconds.

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 1,800 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 aP nasonic 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 Pro2ram 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 2007, 66 analyses were completed on 16 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 66 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.

All of the 66 analyses were within the acceptance criteria, except for one Gross Beta on Filter for Cs-137 result which fell outside the acceptable criteria (NCR # 267497). During 2007, each individual measurement (691 analyses) was evaluated; with all but twenty-five (25) of the individual measurements falling within the acceptable criteria (NCR # 273324). Any results that lie outside the ratio criteria will have an evaluation performed to identify any recommended remedial actions and to reduce anomalous errors. Complete documentation of any evaluation will be available and provided to the NRC upon request.

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 that 500 square feet, producing broadleaf vegetables

> The nearest milk animal 39

The primary methods are visual inspection from the roadside within the five (5) mile radius and personal contact with the individuals.

2007 Land-Use Census Results The 2006 and 2007 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 2006 to 2007. No gardens were located within 5 miles of the plant for the NE, S, and WNW sectors. All the gardens located in 2007 were the same as 2006, except where the previous year's survey did not find a garden in the NW sector the 2007 survey did locate a garden at 2.4 miles in the NW sector and a garden was located in a closer proximity to the plant in the SE sector in 2007 at 2.6 miles. No meat animals were found in the NE, S, SSW, WNW, and NW sectors in 2007. All meat animals located in 2007 were the same as 2006. The dairy in the SSE sector at 7.0 miles from the plant ceased operation in 1997 and there still remain no milk animals near the plant. Harris Lake County Park was included in the 2007 survey, even though there are not yet permanent residents on site. There are plans in the future for rangers and a campground.
