1. EXECUTIVE

SUMMARY

This document is a detailed report of the 2009 Surry Power Station Radiological Environmental Monitoring Program (REMP). Radioactivity levels from January 1 through December 31, 2009, in air, water, silt, shoreline sediment, milk, aquatic biota, food products and direct exposure pathways have been analyzed, evaluated and summarized.

The REMP is designed to confirm that radiological effluent releases are As Low As is Reasonably Achievable (ALARA), no undue environmental effects occur and the health and safety of the public are protected.

The program also detects any unexpected environmental processes that could allow radiation accumulations in the environment or food pathway chains.Radiation and radioactivity in the environment are monitored within a 20-mile radius of the station. Surry Power Station personnel collect a variety of samples within this area. A number of sampling locations for each medium are selected using available meteorological, land use, and water use data. Two types of samples are obtained.

The first type, control samples, is collected from areas that are beyond the measurable influence of Surry Power Station or any other nuclear facility.

These samples are used as reference data. Normal background radiation levels, or radiation present due to causes other than Surry Power Station, can be compared to the environment surrounding the station. Indicator samples are the second sample type obtained.

These samples show how much radiation is contributed to the environment by the station. Indicator samples are taken from areas close to the station where any station contribution will be at the highest concentration.

Prior to station operation, samples were collected and analyzed to determine the amount of radioactivity present in the area. The resulting values are used as a"pre-operational baseline." Analysis results from the indicator samples are compared to control sample values and the pre-operational baseline to determine if changes in radioactivity levels are attributable to station operations, or causes such as the Chernobyl accident or natural variation.

GEL Laboratories LLC and Teledyne Brown Engineering, Inc. provide radioanalyses for this program and Global Dosimetry Solutions, Inc. provides thermoluminescent dosimetry (TLD) services.

Participation in an Interlaboratory Comparison Program provides an independent check of sample measurement precision and accuracy.

Typically, radioactivity levels in the environment are so low that analysis values frequently fall below the minimum detection limits of state-of-the-art measurement methods. Because of this, the United States Nuclear Regulatory Commission (USNRC) requires that equipment used for radiological environmental monitoring must be able to detect specified minimum Lower Limits of Detection (LLDs). This ensures that analyses are as accurate as 5 possible.

The USNRC also mandates a reporting level for radionuclides.

Licensed nuclear facilities must report the radionuclide activities in those environmental samples that are equal to or greater than the specified reporting level.Environmental radiation levels are sometimes referred to as a percent of the reporting level.Analytical results are reported for all possible radiation exposure pathways to man. These pathways include airborne, aquatic, terrestrial and direct radiation exposure.

The airborne exposure pathway includes radioactive airborne iodine and particulates.

The 2009 airborne results were similar to previous years. No station related radioactivity was detected and natural radioactivity levels remained at levels consistent with past years' results. Aquatic exposure pathway samples include well and river water, silt and shoreline sediments, crabs, fish, clams and oysters. Naturally occurring potassium-40 was detected at average environmental levels. No man-made radionuclides were detected in well water. This trend is consistent throughout the operational environmental monitoring program. No man-made radionuclides were detected in river water. Silt samples indicated the presence of cesium- 137 and naturally occurring radionuclides.

The cesium- 137 activity was present in the control and indicator locations and is attributable to global fallout from past nuclear weapons testing and nuclear accidents such as Chernobyl.

Shoreline sediment, which may provide a direct exposure pathway, contained no station related radionuclides.

Naturally occurring potassium-40 and thorium-228 were detected at average environmental levels. The terrestrial exposure pathway includes milk and food products.

Iodine-131 was not detected in any 2009 milk samples and has not been detected in milk prior to or since the 1986 Chernobyl accident.

Strontium-90 was again detected in milk and this activity is attributable to past atmospheric nuclear weapons testing. No man-made radionuclides were detected in food product samples. Consistent with historical data, naturally occurring potassium-40 was detected in milk and food products.

The direct exposure pathway measures environmental radiation doses using TLDs. TLD results have remained relatively constant over the years.During 2009, as in previous years, the operation of Surry Power Station has created no adverse environmental effects or health hazards. The maximum total body dose calculated for a hypothetical individual at the station site boundary due to liquid and gaseous effluents released from the station during 2009 was 0.001 millirem.

For reference, this dose may be compared to the 620 millirem average annual exposure to every person in the United States from natural and man-made sources. Natural sources in the environment provide approximately 50% of radiation exposure to man, while nuclear power contributes less than 0.1%.These results demonstrate compliance with federal and state regulations and also demonstrate the adequacy of radioactive effluent controls at Surry Power Station.6

2. PROGRAM DESCRIPTION 2.1 Introduction This report documents the 2009 Surry Power Station operational Radiological Environmental Monitoring Program (REMP). The Dominion Surry Power Station is located on the Gravel Neck peninsula adjacent to the James River, approximately 25 miles upstream of the Chesapeake Bay. The site consists of two units, each with a pressurized water reactor (PWR) nuclear steam supply system and turbine generator furnished by Westinghouse Electric Corporation.

Each unit is designed with a gross electrical output of 855 megawatts electric (MWe). Unit 1 achieved commercial operation on December 22, 1972, and Unit 2 on May 1, 1973.The United States Nuclear Regulatory Commission regulations (10CFR50.34a) require that nuclear power plants be designed, constructed and operated to keep levels of radioactive material in effluents to unrestricted areas As Low As is Reasonably Achievable.

To ensure these criteria are met, the operating license for Surry Power Station includes Technical Specifications that address the release of radioactive effluents.

In-plant monitoring is used to ensure that these release limits are not exceeded.

As a precaution against unexpected or undefined environmental processes which might allow undue accumulation of radioactivity in the environment, a program for monitoring the station environs is also included in Surry Power Station Technical Specifications.

Dominion personnel are responsible for collecting the various indicator and control environmental samples. Global Dosimetry Solutions Incorporated is responsible for processing the TLDs. GEL Laboratories LLC and Teledyne Brown Engineering are responsible for sample analyses.

The results of the analyses are used to determine if changes in radioactivity levels may be attributable to station operations.

Measured values are compared with control values, which vary with time due to external events, such as cosmic ray bombardment, nuclear weapons test fallout and seasonal variations of naturally occurring radionuclides.

Data collected prior to station operation is used to indicate the degree of natural variation to be expected.

This pre-operational data is compared with data collected during the operational phase to assist in evaluating any radiological impact of station operation.

Occasionally, samples of environmental media may show the presence of man-made radionuclides.

As a method of referencing the measured radionuclide concentrations in the sample media to a dose consequence to man, the data is compared to the reporting level concentrations listed in the USNRC Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants", (December, 1975) and VPAP-2103S, Offsite Dose Calculation Manual (Surry).7 These concentrations are based upon the annual dose commitment recommended by 1OCFR50, Appendix I, to meet the criterion of "As Low As is Reasonably Achievable." This report documents the results of the REMP for 2009 and satisfies the following objectives of the program:) To provide measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposure of the maximum exposed member of the public resulting from station operations.

To supplement the radiological effluent monitoring program by verifying that radioactive effluents are within allowable limits.> To identify changes in radioactivity in the environment.

> To verify that station operations have no detrimental effect on the health and safety of the public.2.2 Sampling and Analysis Program Table 2-1 summarizes the 2009 sampling program for Surry Power Station. All samples listed in Table 2-1 are taken at indicator locations except those labeled"control." Dominion personnel collect all samples listed in Table 2-1.Table 2-2 summarizes the analysis program conducted by GEL Laboratories LLC, Teledyne Brown Engineering and Global Dosimetry Solutions for Surry Power Station. All samples, with the exception of the TLDs, are shipped to GEL Laboratories LLC, located in Charleston, SC, or Teledyne Brown Engineering, located in Knoxville, TN, for analysis.

The TLDs are shipped to Global Dosimetry Solutions, located in Costa Mesa, CA, for processing.

Results are considered positive when the measured value exceeds 2y uncertainty.

GEL Laboratories LLC and Teledyne Brown Engineering analytical methods meet the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical Position, "An Acceptable Radiological Environmental Monitoring Program", (November 1979, Revision 1) and the Surry ODCM.Data are 1.2.3.4.5.6.7.8.9.10.11.12.13.14.given according to sample type as indicated below.Gamma Exposure Rate Air Particulates, Weekly Gross Beta Radioactivity Air Particulates, Weekly I- 131 Air Particulates, Quarterly Gamma Spectroscopy Cow Milk Food Products Well Water River Water Silt Shoreline Sediment Fish Oysters Clams Crabs 28 TABLE 3-2: GAAMM EXPOSURE RA TE Sunry Power Station, Surry County, Virginia -2009 mRIS td Month +/- 2 S igma Page 1 of 1 STATION FIRST SECOND THIRD FOURTH AVERAGE NUMBER QUARTER QUARTER QUARTER QUARTER +/- 2 SIGMA 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39-C 40-C 41 -C 42 43 3.9 +/- 0.5 4.2 +/- 1.2 3.0 +/- 0.6 3.7 +/- 1.1 3.3 +/- 0.5 3.9 +/- 1.4 3.5 +/- 1.0 6.2 +/- 0.7 4.5 +/- 0.7 2.0 +/- 0.1 3.8 +/- 0.8 3.3 +/- 1.2 3.4 +/- 1.4 4.9 +/- 0.9 4.3 +/- 0.2 2.0 +/- 0.3 2.7 +/- 1.0 2.3 +/- 1.0 2.8 +/- 1.6 1.4 +/- 0.4 4.5 +/- 0.3 2.7 +/- 1.5 2.7 +/- 0.4 4.1 +/- 1.1 2.2 +/- 0.4 2.3 +/- 0.4 2.0 +/- 0.9 2.2 +/- 1.1 1.2 +/- 0.3 2.4 +/- 0.7 3.5 +/- 0.3 2.5 +/- 0.6 4.7 +/- 1.2 3.2 +/- 0.3 3.0 +/- 1.7 4.7 +/- 0.4 2.3 +/- 1.3 3.8 +/- 0.6 5.5 +/- 1.5 2.5 +/- 0.4 2.4 +/- 0.2 3.6 +/- 0.5 4.0 +/- 0.4 3.5 +/- 0.2 3.0 +/- 0.2 3.9 +/- 0.9 3.4 +/- 0.5 2.9 +/- 0.7 4.7 +/- 0.5 3.7 +/- 1.7 2.8 +/- 0.8 2.8 +/- 0.7 3.6 +/- 0.6 3.2 +/- 0.2 3.2 +/- 0.4 3.2 +/- 1.0 2.0 +/- 0.7 2.1 +/- 0.3 2.1 +/- 0.6 2.1 +/- 0.4 1.7 +/- 0.4 3.1 +/- 0.7 3.1 +/- 0.8 2.5 +/- 0.4 2.8 +/- 0.2 2.2 +/- 0.4 1.8 +/- 0.4 1.6 +/- 0.2 1.7 +/- 0.3 1.5 +/- 0.4 2.3 +/- 0.8 2.5 +/- 0.3 2.4 +/- 0.4 3.2 +/- 0.4 3.5 +/- 0.8 2.4 +/- 0.9 4.5 +/- 0.4 1.8 +/- 0.5 2.6 +/- 0.9 4.4 +/- 0.3 2.4 +/- 0.2 2.1 +/- 0.5 4.7 +/- 1.1 4.0 +/- 0.6 4.1 +/- 0.7 3.8 +/- 0.5 5.2 +/- 1.6 4.0 +/- 0.9 3.7 +/- 0.7 5.3 +/- 0.5 4.1 +/- 0.5 2.7 +/- 0.1 3.5 +/- 1.2 3.6 +/- 0.9 3.8 +/- 0.6 4.4 +/- 0.6 3.4 +/- 0.2 2.0 +/- 2.9 2.9 +/- 0.3 2.9 +/- 1.3 2.9 +/- 0.5 1.9 +/- 0.5 3.8 +/- 0.9 2.8 +/- 0.5 3.6 +/- 0.4 3.9 +/- 0.4 2.5 +/- 0.8 2.7 +/- 0.8 2.3 +/- 0.4 2.6 +/- 0.4 2.1 +/- 0.9 2.7 +/- 1.2 3.0 +/- 0.6 2.8 +/- 0.5 3.7 +/- 0.6 3.7 +/- 0.2 3.1 +/- 0.7 4.9 +/- 1.0 2.7 +/- 0.4 3.1 +/- 0.9 5.6 +/- 1.4 3.2 +/- 0.2 2.3 +/- 3.6 5.1 +/- 0.4 5.1 +/- 0.2 4.1 +/- 0.3 4.6 +/- 0.9 4.6 +/- 0.7 4.4 +/- 0.7 3.9 +/- 0.3 6.2 +/- 0.3 5.1 +/- 1.1 2.7 +/- 0.3 3.8 +/- 0.8 3.8 +/- 0.7 4.2 +/- 0.3 4.6 +/- 0.7 4.6 +/- 0.4 2.5 +/- 0.9 2.8 +/- 0.5 2.4 +/- 1.7 2.9 +/- 1.2 2.2 +/- 1.8 4.1 +/- 1.8 3.1 +/- 0.5 4.3 +/- 2.0 4.0 +/- 1.0 2.9 +/- 0.2 2.8 +/- 0.4 2.1 +/- 0.3 2.7 +/- 0.3 2.5 +/- 0.4 2.3 +/- 0.1 3.0 +/- 0.4 3.3 +/- 0.6 4.0 +/- 0.6 5.1 +/- 0.3 3.2 +/- 0.5 6.0 +/- 2.4 3.0 +/- 1.0 3.6 +/- 0.9 6.5 +/- 0.6 3.2 +/- 1.1 2.6 +/- 0.3 4.3 +/- 1.4 4.3 +/- 1.1 3.7 +/- 1.1 3.8 +/- 1.3 4.3 +/- 1.7 3.9 +/- 0.8 3.5 +/- 0.9 5.6 +/- 1.5 4.4 +/- 1.2 2.6 +/- 0.7 3.5 +/- 0.9 3.6 +/- 0.4 3.7 +/- 0.9 4.3 +/- 1.5 3.9 +/- 1.4 2.1 +/- 0.5 2.6 +/- 0.7 2.4 +/- 0.7 2.7 +/- 0.8 1.8 +/- 0.7.3.9 +/- 1.2 2.9 +/- 0.4 3.3 +/- 1.7 3.7 +/- 1.2 2.5 +/- 0.7 2.4 +/- 0.9 2.0 +/- 0.6 2.3 +/- 0.9 1.8 +/- 1.2 2.4 +/- 0.4 3.0 +/- 0.8 2.8 +/- 0.8 3.9 +/- 1.3 3.9 +/- 1.7 2.9 +/- 0.7 5.0 +/- 1.3 2.5 +/- 1.0 3.3 +/- 1.1 5.5 +/- 1.7 2.8 +/- 0.9 2.4 +/- 0.4 29

4. DISCUSSION OF RESULTS Data from the radiological analyses of environmental media collected during 2009 and tabulated in Section 3, are discussed below. The procedures and specifications followed in the laboratory for these analyses are as required in the GEL Laboratories LLC and the Teledyne Brown Engineering quality assurance manuals and laboratory procedures.

In addition to internal quality control measures performed by the laboratories, they also participate in an Interlaboratory Comparison Program. Participation in this program ensures that independent checks on the precision and accuracy of the measurements of radioactive material in environmental samples are performed.

The results of the Interlaboratory Comparison Program are provided in Appendix B.The predominant radioactivity detected throughout 2009 was from external sources, such as fallout from nuclear weapons tests (cesium-137, strontium-90) and naturally occurring radionuclides.

Naturally occurring nuclides such as beryllium-7, potassium-40, and thorium-228 were detected in numerous samples.The following is a discussion and summary of the results of the environmental measurements taken during the 2009 reporting period.4.1 Gamma Exposure Rate A thermoluminescent dosimeter (TLD) is an inorganic crystal used to detect ambient radiation.

Two TLDs, made of CaF and LiF elements and specifically designed for environmental monitoring, are deployed at each sampling location.TLDs are placed in two concentric rings around the station. The inner ring is located in the vicinity of the site boundary, and the outer ring is located at approximately five miles from the station. TLDs are also placed in special interest areas, such as population centers and nearby residences.

Additional TLDs serve as controls.

Ambient radiation comes from naturally occurring radioisotopes in the air and soil, radiation from cosmic origin, fallout from nuclear weapons testing, station effluents and direct radiation from the station.The results of the TLD analyses are presented in Table 3-2. Figure 4-1 shows a historical trend of TLD exposure rate measurements, comparing the average of indicator TLDs located near the site boundary and at 5 miles to the average of all control TLD locations.

Control and indicator averages indicate a steady relationship.

Once a week the samples are collected and analyzed for gross beta activity.

Results of the weekly gross beta analyses are presented in Table 3-3. A review of the results from control and indicator locations continues to show no significant variation in measured activities (see Figure 4-2 and 4-3). This indicates that any station contribution is not measurable.

Gross beta activity found during the pre-operational and early operating period of Surry Power Station was higher because of nuclear weapons testing. During that time, nearly 740 nuclear weapons were tested worldwide.

In 1985 weapons testing ceased, and with the exception of the Chernobyl accident in 1986, airborne gross beta results have remained steady.50 Figure 4-2: 2009 GROSS BETA IN AIR PARTICULATES 0.060 0.050 0.040.--0.030 , 0.020 " 0.010 f 0.000 !----0 '- A 0n-ao --. -Ag ('n 0r l 0 t ' w--- Avg Indicator

Once a week the charcoal cartridge samples are collected and analyzed.

The results of the analyses are presented in Table 3-4. All results are below the lower limit of detection.

No positive iodine-131 was detected.

These results are similar to pre-operational data and the results of samples taken prior to and after the 1986 accident in the Soviet Union at Chernobyl.

4.4 Air Particulate Gamma The air particulate filters from the weekly gross beta analyses are composited by location and analyzed quarterly by gamma spectroscopy.

The results are listed in Table 3-5. The results indicate the presence of naturally occurring beryllium-7, which is produced by cosmic processes.

No man-made radionuclides were identified.

These analyses confirm the lack of station effects.4.5 Cow Milk Analysis of milk samples is generally the most sensitive indicator of fission product existence in the terrestrial environment.

This, in combination with the fact that consumption of milk is significant, results in this pathway usually being the most critical from the plant release viewpoint.

This pathway also shows measurable amounts of nuclear weapons testing fallout. Therefore, this media needs to be evaluated very carefully when trying to determine if there is any station effect.Analysis results for cow milk are contained in Table 3-6. All results show a lack of detectable iodine-131 above the LLD of 1 pCi/L. Results of gamma spectroscopy indicate no other detectable station related radioactivity in the milk samples. In years past, cesium- 137 has been detected sporadically.

The occurrences were attributed to residual global fallout from past atmospheric weapons testing. Cs-137 was not detected at a level above the LLD in 2009.At the request of the Commonwealth of Virginia, a quarterly composite sample is prepared from the monthly milk samples from the Colonial Parkway collection station. The composite samples are analyzed for strontium-89 and strontium-90.

Sr-90 was detected in one of the four composites analyzed at a concentration of 1.12 pCi/L. The average Sr-90 concentration for the ten year period of 1999 to 2009 is 1.82 pCi/L. Sr-90 is not a component of the station radiological effluents.

The Sr-90 detected is a product of nuclear weapons testing fallout which has been well documented.

52 I, j, 4.6 Food Products Three samples were collected and analyzed by gamma spectroscopy.

The results of the analyses are presented in Table 3-7. As expected, naturally occurring potassium-40 was detected in all samples. The average concentration is consistent with that observed in previous years. Naturally occurring thorium-228 was also detected in one of three samples. No station related radioactivity was detected.4.7 Well Water Well water is not considered to be affected by station operations because there are no discharges made to this pathway. However, Surry Power Station monitors well water quarterly at three indicator locations and analyzes for gamma radiation and for tritium. The results of these analyses are presented in Table 3-8. Consistent with past monitoring, no station related radioactivity was detected.

Naturally occurring potassium-40 and actinium-228 were detected in one sample each. No gamma emitting isotopes were detected during the pre-operational period.4.8 River Water Samples of the James River water are collected monthly and the results are presented in Table 3-9. All samples are analyzed by gamma spectroscopy.

The monthly samples are also composited and analyzed for tritium on a quarterly basis. Naturally occurring potassium-40, thorium-228 and radium-226 were detected in some samples. No station related radioactivity was detected.4.9 Silt Silt is sampled to evaluate any buildup of radionuclides in the environment due to the operation of the station. Sampling of this pathway provides a good indication of the dispersion effects of effluents to the river. Buildup of radionuclides in silt could indirectly lead to increasing radioactivity levels in clams, oysters, crabs and fish.Samples of silt are collected from two locations, one upstream and one downstream of the station. The results of the gamma spectroscopy analyses are presented in Table 3-10. Trend graphs of cobalt-60 and cesium-137 in silt appear in Figures 4-4 and 4-5.Historically, cobalt-60 has been detected in samples obtained from the indicator location (SD). Cobalt-60 has not been detected since 2003.53 Cesium-137 was detected, as expected, in both the control and indicator samples.The levels detected indicate a continual decreasing trend seen for over a decade.The detection of cesium-137 in both the control and indicator samples and decreasing levels indicate that the presence of cesium-137 is the result of accumulation and runoff into the river of residual weapons testing fallout. Its global presence has been well documented.

During the pre-operational period, cesium-137 was detected in most silt samples with an average concentration as indicated in Figure 4-5. In 2009, cesium-137 was detected with an average indicator location concentration of 214 pCi/kg and an average control location concentration of 184 pCi/kg. These activities continue to represent fallout from nuclear weapons testing. Both indicator and control cesium-137 activities trend closely as shown in Figure 4-5.Figure 4-4: COBALT-60 IN SILT 1.OE+04 1.OE+03 1.OE+02 C., 1.0E+01 L.OE+00 Cl ý 0 00 0 l ' 00 0 C ' 00 0 lcf \ 00 N N N N 00 00 00 00 00 CNcr 0ý N ON 0ý ,C 0 0 0 0 Control -Chickahominy

Station Discharge

-Asg Pre-Op -Required LLD 4.10 Shoreline Sediment Shoreline sediment, unlike river silt, may provide a direct dose to humans.Buildup of radionuclides along the shoreline may provide a source of direct exposure for those using the area for commercial and recreational uses. The results are presented in Table 3-11.The naturally occurring radionuclides potassium-40 and thorium-228 were detected at concentrations equivalent to normal background activities.

The activities of these radionuclides indicate a steady trend. There were no radionuclides attributable to the operation of the station found in any shoreline sediment samples.4.11 Fish The radioactivity measured in fish sampled from the station discharge canal and analyzed by gamma spectroscopy is presented in Table 3-12. These results are the same as those seen over the last decade. No activity was observed in this media except for naturally occurring potassium-40.

55 4.12 Oysters Oysters are collected from two different locations.

The results of the oyster analyses are presented in Table 3-13.There were no gamma emitting radionuclides detected in oysters sampled except for naturally occurring potassium-40.

No station related radioactivity has been detected in this media since 1991. The absence of station related radionuclides is attributable to the replacement of steam generators in 1982 and past improvements made to liquid effluent treatment systems.4.13 Clams Clams are analyzed from four different locations.

The results of the gamma spectroscopy analyses are presented in Table 3-14. Like oysters, no station related radioactivity was detected.

Naturally occurring potassium-40 and thorium-228 were detected.4.14 Crabs A crab sample was collected in June from the station discharge canal and analyzed by gamma spectroscopy.

The results of the analysis are presented in Table 3-15. Other than naturally occurring potassium-40, no other gamma emitting radionuclides were detected in the sample. This is consistent with pre-operational data and data collected over the past decade.56

5. PROGRAM EXCEPTIONS There were four REMP exceptions for scheduled sampling and analysis during 2009.The gross beta minimum detectable concentration (MDC) was 1.16E-02 pCi/m 3.for the November 17 Hog Island Reserve (HIR) air sample. This concentration is greater than the lower limit of detection (LLD) concentration of 1.00E-02 pCi/m 3.Although an MDC is a posteriori measurement, Surry Power Station requires that this value be less than or equal to the required LLD. This ensures that REMP samples are analyzed to required program elements.

The cause for the higher MDC was a lower than normal sample volume due to loss of power at the HIR air sampling station. The loss of power resulted from a nor'easter that moved through the area during the sample period. Detection of gross beta activity in air samples is routine. Detectable gross beta activity was determined in this HIR air sample with the reduced volume and normal sample count time. Due to the detectable activity, the slightly elevated MDC was considered minor and a follow-on analysis to meet the 1.00E-02 pCi/m 3 MDC was not requested.

The iodine-131 minimum detectable concentration (MDC) was 7.01E-02 pCi/m 3 for the November 03 Fort Eustis (FE) air sample and 7.16E-02 pCi/m 3 for the November 17 Hog Island Reserve (HIR) air sample. These concentrations are greater than the lower limit of detection (LLD) concentration of 7.OOE-02 pCi/m 3.For the second half of 2009, an efficiency correction factor normally used to determine the iodine- 131 concentration in air samples was not applied. Upon discovery of this error, the correction factor was applied to all air samples for the second half of 2009. This resulted in the higher than normal MDCs for these two air samples. A reanalysis of the two samples was not performed due to the short half-life of iodine- 131 and the extended time period between sample collection and discovery of the correction factor error.During the March 2008 clam sampling campaign, clams were not found at the Hog Island Point sample location.

An alternate sampling location, Jamestown Island, was selected and sampled throughout 2008.- In 2009, clams continued to be sampled at the Jamestown Island location in place of the Hog Island Point location.57

6. CONCLUSIONS The results of the 2009 Radiological Environmental Monitoring Program for Surry Power Station have been presented in previous sections.

This section presents conclusions for each pathway.Direct Radiation Exposure Pathway -Control and indicator location averages continue to indicate a steady relationship and trend over the long term.Airborne Exposure Pathway -Analysis of charcoal cartridge samples for radioiodines indicated no positive activity was detected.

Quarterly gamma isotopic analyses of the composite particulate samples identified only naturally occurring beryllium-7.

Air particulate gross beta concentrations at all of the indicator locations for 2009 trend well with the control location.BMilk -Milk samples are an important indicator measuring the effect of radioactive iodine and radionuclides in airborne releases.

Cesium-137 and iodine-131 were not detected in any of the thirty-six samples. Naturally occurring potassium-40 was detected at a similar level when compared to the average of the previous year.Strontium-90 was detected in one of four samples this year at a concentration of 1.12 pCi/L. Strontium-90 is not a component of station effluents, but rather, a product of nuclear weapons testing fallout.Food Products -As expected, naturally occurring potassium-40 was detected in all three samples and naturally occurring thorium-228 was detected in one of three samples. In the past, cesium-137 has occasionally been detected in these samples and is attributable to global fallout from past nuclear weapons testing. Cesium-137 was not detected in any of the three samples collected in 2009.Well Water -Well water samples were analyzed and the analyses indicated that there were no man-made radionuclides present. This trend is consistent throughout the monitoring period. No radioactivity attributable to the operation of the station was identified.

> River Water -All river water samples were analyzed for gamma emitting radionuclides.

Only the naturally occurring radionuclides potassium-40 thorium-228 and radium-226 were detected.

Tritium was not detected at levels exceeding the lower limit of detection for any samples in 2009.> Silt -Cesium-137 was detected in both the control and indicator samples.The presence of cesium- 137 is attributable to residual weapons testing fallout; its presence has been well documented.

Cobalt-60 has not been 58 detected since 2003.Shoreline Sediment -Naturally occurring radionuclides were detected at concentrations equivalent to normal background activities.

There were no radionuclides attributable to the operation of Surry Power Station found in any sample.Aquatic Biota Fish -As expected, naturally occurring potassium-40 was detected.

There were no other gamma emitting radionuclides detected in any of the fish samples.Oysters and Clams -Other than naturally occurring potassium-40 and thorium-228, there were no other gamma emitting radionuclides detected in any of the oyster or clam samples.Crabs -Naturally occurring potassium-40 was detected.

No other gamma emitting radionuclides were detected.59 REFERENCES 60 References

SUMMARY

OF INTERLABORATORY COMPARISONS Year 2009 65 EfTRODUCTION This appendix covers the Interlaboratory Comparison Program (ICP) of GEL Laboratories LLC (GEL) and Teledyne Brown Engineering (TBE). GEL and TBE use QA/QC samples provided by Eckert & Ziegler Analytics, Inc., Environmental Resource Associates (ERA) and the Mixed Analyte Performance Evaluation Program (MAPEP) to monitor the quality of analytical processing associated with the REMP. Each provider has a documented Quality Assurance program and the capability to prepare Quality Control materials traceable to the National Institute of Standards and Technology (NIST). The providers supply the samples to GEL and TBE, and upon receipt, the laboratories perform the analyses in a normal manner. The results are then reported to the provider for evaluation.

The suite of QA/QC samples is designed to provide sample media and radionuclide combinations that are offered by the providers and included in the REMP and typically includes:) milk for gamma nuclides and low-level iodine- 131 analyses,> milk for Sr-89 and Sr-90 analyses,> water for gamma nuclides, low-level iodine- 131, and gross beta analyses,> water for tritium, Sr-89, and Sr-90 analyses,> cartridge for l- 13 1 analyses,> air filter for gamma nuclide, gross beta, and Sr-90 analyses.The accuracy of each result reported to Eckert & Ziegler Analytics, Inc. is measured by the ratio of GEL and TBE result to the known value. Accuracy for all other results is based on statistically derived acceptance ranges calculated by the providers.

An investigation is undertaken whenever the ratio or reported result fell outside of the acceptance range.RESULTS The GEL and TBE ICP results are included in the following tables for the first through the fourth quarters of 2009. One result did not meet the acceptance criteria and is discussed as follows.* 2nd quarter milk -The root cause of the Sr-90 failure was determined to be a batch quality control issue. The carrier yield for the second separation was greater than 100%. The elevated yield caused the Sr-90 result to be biased low.66 I j ECKERT & ZIEGLER ANALYTICS ENVIRONMENTAL RADIOACTIVITY CROSS CHECK PROGRAM GEL LABORATORIES LLC (PAGE 1 OF 2)Identification Reported Known Quarter Number Matrix Nuclide Units Value (a) Value (b) Ratio (c) Evaluation (d)1st Quarter 2009 E6582-278 Charcoal 1-131 E6584-278 Milk 1-131 Ce-1 41 Cr-51 Cs-1 34 Cs-1 37 Co-58 Mn-54 Fe-59 Zn-65 Co-60 pCi pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L 77.7 79.7 97.8 297 90.6 116 123 133 116 172 150 75.5 122 392 119 144 159 180 128 224 192 79.4 79.3 94.9 305 93.7 111 119 128 99.9 156 142 69 120 387 119 141 151 162 127 197 180 0.98 1.01 1.03 0.97 0.97 1.04 1.03 1.04 1.16 1.10 1.06 1.09 1.02 1.01 1.00 1.02 1.05 1.11 1.01 1.13 1.06 E6585-278 Water 1-131 Ce-141 Cr-51 Cs- 134 Cs-137 Co-58 Mn-54 Fe-59 Zn-65 Co-60 Footnotes are on page 2 of 2.67 ECKERT & ZIEGLER ANALYTICS ENVIRONMENTAL RADIOACTIVITY CROSS CHECK PROGRAM GEL LABORATORIES LLC (PAGE 2 OF 2)Identification Reported Known Quarter Number Matrix Nuclide Units Value (a) Value (b) Ratio (c) Evaluation (d)2nd Quarter 2009 E6729-278 Charcoal 1-131 pCi 92.7 95.5 E6730-278 Milk Sr-89 pCi/L 85.1 Sr-90 pCi/L 10.9 E6731-278 Milk 1-131 Ce-1 41 Cr-51 Cs-1 34 Cs-137 Co-58 Mn-54 Fe-59 Zn-65 Co-60 pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L pCi/L 89.8 284 404 158.0 192 94.8 142 123 179 315 85.2 229 311 137 151 72.1 107 90.4 138 242 112 16.7 102.0 284 400 166 192 91.9 137 122 175 312 88.3 216 304 126 146 70 104 92.9 133 237 0.97 0.76 0.65 0.88 1.00 1.01 0.95 1.00 1.03 1.04 1.01 1.02 1.01 0.97 1.06 1.02 1.09 1.04 1.03 1.03 0.97 1.04 1.02 A A N A A A A A A A A A A A A A A A A A A A A E6732-278 Water 1-131 Ce-141 Cr-51 Cs-134 Cs-137 Co-58 Mn-54 Fe-59 Zn-65 Co-60 (a) GEL reported result.(b) Reference value.(c) Ratio GEL to Eckert& Ziegler Analytics.(d) Evaluation:
