SUMMARY
Implementation of the DC Cook Nuclear Plant Radiological Environmental Monitoring Program (REMP) continued during the period January through December 2002, in compliance with station Technical Specifications and Off-Site Dose Calculation Manual.
Radiochemical and radiometric analysis of REMP samples was performed to allow for the detection of station-related radioactivity. Samples included air particulate filters and chartoal cartridges, fruit, water (drinking, well and surface), milk, and Lake Michigan fish and sediment. Also, thermoluminescent dosimeters (TLDs) were used to measure direct gamma exposure at various locations up to a distance of 26 miles from the station.
During the evaluation of analyses results, it was necessary to consider the variability of natural and man-made sources of radioactivity, distribution in the environment and uptake in environmental media. The potential variability was dependent on many possible factors including:
contributions from cosmogenic radioactivity ground water dynamics station related release rates past spatial variability of radioactive fallout from nuclear weapons tests and the on-going redistribution of this fallout soil characteristics farming practices feed type Since these factors had the potential to cause significant variation in sample analysis results, they were considered during the evaluation of detected radioactivity.
Based on the evaluation of analyses results, it was determined that radioactivity detected by the REMP was predominantly from outside sources, such as fallout from nuclear weapons tests and naturally occurring radionuclides. Examples include the following:
Four of four Lake Sediment samples contained naturally occurring K40 and one of four samples contained naturally occurring AcTh-228.
Three of three Grape and Broad Leaf samples contained naturally occurring K40 and one of three samples contained naturally occurring Be-7.
One of eight Lake Michigan fish samples contained Cs-137. Detection of this nuclide has historically been attributed to residual fallout from nuclear weapons tests and the levels detected were consistent with data contained in DC Cook's "Summary of the Preoperational Radiological Monitoring Program".
No instances of detectable radioactivity attributable to 2002 station operation were noted and no sample analysis results exceeded or approached specified reporting levels.

INTRODUCTION 2.1 General Plant Site Information The Indiana Michigan Power Company DC Cook plant is located on the southeastern shore of Lake Michigan approximately one mile northwest of Bridgman, Michigan. The site consists of two pressurized water reactors: Unit 1, 1095 MWE and Unit 2, 1152 MWE. Unit I achieved initial criticality on January 18, 1975 and Unit 2 on March 10, 1978.
2.2 Program Design The Radiological Environmental Monitoring Program for the DC Cook Nuclear Plant was designed with specific objectives:
To provide an early indication of the appearance or accumulation of any radioactive material in the environment caused by the DC Cook Plant activities.
To provide assurance to regulatory agencies and the public that the environmental/dose impact of the DC Cook Plant operation is known and within anticipated limits.
To verify the adequacy and proper functioning of station effluent controls and monitoring systems.
To comply with regulatory requirements and Station Technical Specifications and provide records to document compliance.
The program was developed to meet the intent of the NRC Regulatory Guide 4.1, Programs for Monitoring Radioactivity in the Environs of Nuclear Power Plants; NRC Regulatory Guide 4.8, Environmental Technical Specifications for Nuclear Power Plants; the NRC Branch Technical Position of November 1979, An Acceptable Radiological Environmental Monitoring Program; and NRC NUREG-0472, Radiological Effluent Technical Specifications for PWR's.
The REMP sampling requirements are given in Attachment 3.19 of the ODCM and summarized in Table 2.1 of this report. The identification of the required sampling locations is also provided in Attachment 3.19 of the ODCM and Table 2.2 of this report. The monitoring locations are shown graphically in Figures 2.1 and 2.2.
2.3 Monitoring Zones The REMP is designed to allow comparison of levels of radioactivity in samples from the area potentially influenced by the plant to levels found in areas not influenced by the plant. The first area monitoring locations are designated as indicators and the second area monitoring locations are designated as controls. The distinction between the two areas, for a particular pathway, is based on relative direction and distance from the plant. Analysis of survey data from the two areas is used to differentiate between radiation due to plant activities and that due to other sources such as atmospheric nuclear weapons test fallout or seasonal variations in the natural background.
2.4 Pathways Monitored Four pathway categories; airborne, waterborne, ingestion, and direct radiation are monitored by the REMP. Each of these categories is monitored by the collection of one or more sample types listed and described below.
Airborne Pathway:
Waterborne Pathway:
Air Particulate Sampling Surface Water Ground Water Drinking Water 3

Sediment Ingestion Pathway:
Food Products (Fruit and Broadleaf Vegetable)
Fish Milk (Broadleaf Vegetation in lieu of Milk, when necessary)
Direct Radiation:
TLD Monitoring 2.5 Descriptions of Monitoring Pathways Sample types and frequency of analysis are given in Table 2.1. The sample locations are listed in Table 2.2 and shown in Figures 2.1, 2.2, and 2.3. The program as described in this report includes both ODCM required and additional or supplemental samples. A description of the sampling program follows and a detailed summary of the analytical methodologies employed by the Framatome-ANP lab is provided in Appendix A.
2.5.1 Air Sampling Continuous air samplers are installed at ten locations as required by the ODCM. The sampling oil-less pumps at these locations operate continuously with sample flow rate between 42 to 70 Ipm. Airborne particulates are collected by passing air through a 47-mm glass-fiber filter. Charcoal cartridges are installed downstream of the particulate filters and are used to collect airborne radioiodine. An Automatic Volume Totalizer is used to measure the total volume of air sampled, total unit run time and volumetric flow rate. Both filters are collected weekly, and to allow for the decay of radon daughter products, the particulate filters are held at least 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> before being analyzed for gross-beta radioactivity (indicated as GR-B in the data tables). The weekly particulate filters are composited by location at the Framatome Lab for a quarterly gamma spectroscopy analysis.
2.5.2 Surface Water Sampling Two 125 milliliter surface water samples are collected from the intake forebay and from two shoreline locations, all within 0.3 miles of the reactors. Samples are composited daily over a month and preserved with nitric acid. All samples receive a gamma isotopic, low level 1-131 and tritium analysis.
2.5.3 Ground Water Sampling Ground water samples are collected quarterly from 14 wells, all within 4300 feet of the reactors. At each well a static water elevation is determined and three well bore volumes are purged from the well using a groundwater pump or equivalent. Two 1-liter and one 125mr samples are then collected and the gamma isotopic aliquot is preserved with nitric acid. Gamma isotopic and tritium analyses are performed.
2.5A Drinking Water Sampling One liter samples are collected daily at the intake of the water purification plants for St. Joseph and Lake Township. The daily samples are composited over 14 days and the gamma isotopic aliquot is preserved with nitric acid. The Quarterly composite is analyzed for H-3.
2.535 Sediment Sampling Lake Michigan shoreline sediment samples are collected semiannually at the same two locations as the surface water samples. Two liters of lake sediment are collected using a small dredge in an area covered part time by wave action. The sediment samples are analyzed for gamma isotopic content.

DC Cook Nuclear Plant Units 18r2 Annual Radiological Environmental Operating Report 2002 2.5.6 Milk Sampling One gallon milk samples are collected from a 500 gallon bulk tank every fourteen days from four farms located between 4.1 and 20.7 miles from the site. A fifth farm is a goat farm located 5.0 miles from the plant site, where no bulk tank is used. The samples are preserved with 40 grams per gallon of sodium bisulfite at the time of collection. Samples are analyzed for low level I-131 and gamma emitting radionuclides.
2.5.7 Fish Sampling Four and one-half pounds of fish are collected two times a year from four locations using gill nets in approximately 20 feet of Lake Michigan water. The edible portions of the fish are analyzed for gamma-emitting radionuclides.
2.5.8 Food Product Sampling Food products are collected annually, at the time of harvest, from three locations. The locations are as close to the site boundary as possible and approximately 20 miles from the site. Each sample consists of at least 300 grams of grapes or broadleafs. The samples are analyzed by gamma isotopic analysis.
2.5.9 Broad Leaf Vegetation Broad Leaf vegetation sampling in lieu of milk collection was discontinued in 2000 due to the re-implementation of the milk sampling program.
2.5.10 TLD Monitoring Direct gamma radiation exposure is continuously monitored with the use of Panasonic UD-801AS I thermoluminescent dosimeters (TLDs). TLDs are posted at 27 locations in the environs surrounding the DC Cook Plant.

RADIOLOGICAL DATA
SUMMARY
TABLES This section summarizes the analytical results of the environmental samples that were collected during 2002. These results, shown in Table 3.1, are presented in a format similar to that prescribed in the NRCs Radiological Assessment Branch Technical Position on Environmental Monitoring (Reference 1). The results are ordered by sample media type and then by radionuclide for the pathways described in Section 2.3. The units for each media type are also given. Table 3.2 provides the same information for TLD direct radiation measurements.
The left-most column contains the radionuclide of interest, the total number of analyses for that radionuclide in 2002, and the number of measurements which exceeded the Reporting Levels found in Table 2.5. The latter are classified as "Non-routine" measurements. The second column lists the required Lower Limit of Detection (LLD) for those radionuclides, which have detection capability requirements specified in Table 2.4. The absence of a value in this column indicates that no LLD is specified in the ODCM for that radionuclide in that media.
For each media type and radionuclide, the remaining three columns summarize the data for the following categories of monitoring locations: (1) the Indicator stations, which are within the range of influence of the plant and which could be affected by plant activities; (2) the station which had the highest mean concentration during 2002, and (3) the Control J
stations, which are beyond the influence of the plant. Direct radiation monitoring stations (using TLDs) are grouped into Indicator and Control stations.
In each of these columns, for each radionuclide, the following are given:
The mean value of all concentrations including negative values and values that are not considered "detectable".
The lowest and highest concentration.
The number of detectable measurements divided by the total number of measurements.
A sample is considered a "detectable measurement' when the concentration exceeds three times its associated standard deviation. The standard deviation on each measurement represents only the random uncertainty associated with the radioactive decay process (counting statistics), and not the propagation of all possible uncertainties in the analytical procedure.
The radionuclides reported in this section represent those that: 1) had a LLD requirement in Attachment 3.20 or, a Reporting Level listed in Attachment 3.21 of the ODCM or 2) had a positive measurement of radioactivity, whether it was naturally-occurring or man-made; or 3) were of specific interest for any other reason. The radionuclides that are routinely analyzed and reported by the FANPEL in a gamma spectroscopy analysis are: AcTh-228, Ag-108m, Ag-1 10m, Ba-140/La-140, Be-7, Ce-141, Ce-144, Co-57, Co-58, Co-60, Cr-51, Cs-134, Cs-137, Fe-59, I-131, K40, Mn-54, Ru-103, Ru-106, Sb-124, Sb-125, Se-75, Zn-65 and Zr-95INb-95.
Data from direct radiation measurements made by TLDs are provided in Table 3.2 in a format essentially the same as above. The complete listing of quarterly TLD data is provided in Table 3.3.

ONS-6 and DOW air samplers remained in service after calibration due dates had been exceeded due to human performance failures. Affected equipment was promptly replaced with calibrated samplers. "As Found" testing indicated this equipment had been functioning properly and an evaluation of air sample analysis results noted no anomalous values. In order to avoid recurrence of this issue, the personnel involved were counseled using appropriate plant processes (example: "Management Action Response Checklists"). Condition Report CR 02246015 was issued.
- 13. 12/111/02tol2119/02:ONS-3 air samples were not collected every seven days as required by the ODCM due to potential for switching evolutions in the 345 KV yard (i.e. possible hazardous conditions).
Actual collection interval was eight days which is within the allowed 25% grace period. No additional action was taken at this time.
4.2 Comparison of Achieved LLD with Requirements.20 ODCM (Table 2.4 in this report) lists the required Lower Limits of Detection (LLDs) for routine environmental sample analyses. As discussed in section 3.5.2 Bases, on occasion, an LLD is not achieved due to situations such as a low sample volume. In such a case, the ODCM requires the identification and discussion of the contributing factors in the Annual Radiological Environmental Operating Report, these are summarized below. Typical sensitivities achieved in the lab analysis are at least 2.5 to 3 times better than that required by the ODCM. For each analysis having an LLD requirement the a posteriori or after the fact LLD calculated for that analysis was compared with the required LLD.

DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 4.3 Results Compared Against Reporting Levels ODCM Section 3.5.2 requires a discussion in the Annual Radiological Environmental Operating Report of any instance that a radionuclide concentration exceeds the reporting levels given in Attachment 3.21 (Table 2A in this report).
Reporting Levels are the environmental concentrations that relate to the ALARA design dose objectives of 10 CFR 50, Appendix L. It should be noted that environmental concentrations are averaged over calendar quarters for the purposes of this comparison, and that Reporting Levels apply only to measured levels of radioactivity due to plant effluents. During 2002, no Reporting Levels were exceeded.
4.4 Data Analysis by Media Type.
The 2002 REMP data for each media type are discussed below. These are arranged in the same order as in Table 3. 1, and are further categorized by pathway. Graphical plots of monitoring data are also shown in Figures 4.1 to 4.5. With respect to data plots, all 2002 results are plotted, whether they are "detectable" or "non-detectable."
4.4.1 Air Particulate Air particulates are collected weekly on 47 mm glass fiber filters at six indicator locations and four control locations, and are analyzed for gross beta radioactivity. Gamma isotopic analyses are performed on the quarterly composites of each location.
As shown in figure 4.1, there is no difference between the average monthly gross beta concentration at the indicator stations and the control stations. Notable in the graph is the distinct annual cycle. The gross beta concentration is seen to fluctuate over the year due to seasonal changes in the naturally occurring airborne radioactivity. The gross beta concentrations at the indicator stations are similar to the control station and fluctuate in the same manner. The step increase in the concentration is most likely due to the use of a new analytical laboratory in 2002 and differences in the equipment calibration.
The quarterly composites of the weekly air particulate filters were analyzed for gamma radioactivity. The results, shown in Tables 3.1, indicate the presence of naturally occurring Be-7, which is produced by cosmic processes. No positive results were observed for any other isotopes.

Ground water samples are collected from fourteen well locations and analyzed for gamma isotopic and tritium. K-40 was identified in five samples and AcTh-228 was identified in one sample, both nuclides are naturally occurring and may be present in ground water. No tritium was identified in any of the samples during 2002. Figures 4.2, 4.3 and 4.4 plot the tritium in ground water since 1980.

DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 4.4.4 Drinking Water Drinking water samples are collected from one indicator and one control station and analyzed for gamma isotopic, gross beta radioactivity and a quarterly composite for tritium. A specific Iodine 131 low-level analysis, performed on all samples to achieve a MDC of I pCi/kg, indicated that no Iodine-131 was present. During 2002, gross beta radioactivity was found in 16 indicator and 17 control samples, leading to the conclusion that the gross beta activity is due to naturally occurring nuclides. While no tritium was identified in any 2002 samples, one control sample did contain naturally occurring K-40. Figure 4.5 shows a plot of the tritium data since 1989. Of note for 2002 is the fact that all data is plotted, whether the results are negative or positive as described above in section 4.4.

A specific Iodine-131 low-level analysis, performed on all samples to achieve a MDC of I pCi/kg, indicated that no Iodine-131 was present. Table 3.1 shows that no gamma emitting nuclides or tritium were detected in any of the samples collected in 2002.
4.4.6 Sediment Semiannual samples of lake sediments are collected from two indicator stations and analyzed for gamma emitting nuclides. During 2002, naturally occurring K-40 was detected in all samples and AcTh-228 was detected in one sample.
5C1 c6
DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 4A.7 Milk Milk samples were collected bi-weekly from three indicator and two control stations during 2002. Typical levels of K-40, ranging from 1200 to 2100 pCi/Kg, was detected in the samples. An iodine-131 specific analysis performed to achieve a MDC of 1 pCi/Kg did not detect any I-131 in the samples.
4A.8 Food Products Vegetable samples (grapes/broad leaf) analyzed for gamma emitting nuclides indicate only the presence of naturally occurring K-40 and Be-7. No other gamma emitting nuclides were detected in any of the samples 4.4.9 Fish Fish samples were collected semiannually at two indicator and two control locations. Cs-137 was observed in one indicator sample and K-40 was detected in all the samples. Although the presence of Cs-137 in this media is historically attributed to residual weapons fallout, the Cs-137 in fish is treated conservatively and an assessment of the dose consequence is provided in Section 5.
4.4.10 Gamma Exposure Rate Direct radiation is continuously measured at 27 locations surrounding the DC Cook Plant with thermoluminescent dosimeters (TLDs). All TLDs are collected quarterly for readout at the FANPEL.
The results in Tables 3.2 and 3.3 show that the mean exposure rates for the Indicator and Control categories are not significantly different in 2002. As shown in Figure 4.6, there is a distinct annual cycle at both indicator and control locations. The lowest point of the cycle occurs during the winter months. This is due primarily to the attenuating effect of the snow cover on radon emissions and on direct irradiation by naturally-occurring radionuclides in the soil. Differing amounts of these radionuclides in the underlying soil, rock or nearby building materials result in different radiation levels between one field site and another.

OFF-SITE DOSE EQUIVALENT COMMITMENTS The purpose of this section is to evaluate off-site dose consequences (dose equivalent commitments) associated with the stations' radioactive liquid and airborne effluents. The method utilizes Regulatory Guide 1.109 / REMODCM models and actual measurements of the concentrations of radioactivity in environmental media to compute the dose consequences resulting from the consumption of these foods.
The standards for the maximum dose to an individual of the general public, taken from 40CFR190, is 25 mRem to the whole body, 75 mRem to the thyroid and 25 mRem to any other organ. These standards are a fraction of the average USA background radiation of 300 mRem per year given in NRCP94.
During 2002, Cs-137 was measured in one out of four fish samples and although attributed to weapons fallout a potential annual dose commitment to a maximum exposed individual of 0.04 mRem (Teen Liver) has been estimated using conservative assumptions regarding consumption rate and a constant Cs-1 37 concentration in fish of 49.0 pCi/kg. This dose is 0.16% of the maximum allowed dose of 25 mRem.

DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 APPENDIX A SYNOPSIS OF ANALYSIS TECHNIQUES
-4 A-I
DC Cook Nuclear Plant Units l&2 Annual Radiological Environmental Operating Report 2002 GROSS ALPHA/BETA ANALYSIS Air particulate samples, collected on a weekly basis aid in verifying the in-plant controls used for monitoring the release of radioactive materials. The samples are transmitted to the laboratory for gross beta and/or gross alpha radioactivity analysis. Air particulate samples are analyzed on a low background alpha/beta gas proportional counting unit, for a predetermined amount of time, following a delay of a 100-hour minimum to allow for the decay of Radon products.
Blank filters, either provided by the client, or of the same size and type as the client filters are used for background subtraction. If the beta activity concentration is greater than 0.2 pCi/m3, the sample may need to be analyzed for individual gamma emitters. Each sample is composited by sampling location and held until the end of the quarter for a gamma isotopic analysis.
Environmental water samples are also analyzed for gross alpha and/or gross beta radioactivity. Measurable amounts of alpha and beta emitting radionuclides, either naturally occurring or artificially produced, are found in most environmental water samples. Gross alpha and gross beta measurements are rapid screening methods which may indicate the need for a more detailed isotopic analysis. Samples are evaporated to near dryness and quantitatively transferred to concentric ring, stainless steel planchets, where the evaporation is completed. A gas proportional counter is used for the measurement of gross alpha/gross beta radioactivity. Solid deposition is an interference in this method and must be accounted for during instrument calibration.
No decay is accounted for in the gross alpha/beta activity concentration calculations since the radionuclides of origin are not known. The minimum detectable concentration depends on sample size, counting system characteristics, background, and counting time. Typical counting times for gross alpha/beta analyses are seventy five minutes for waters and sixty minutes for air particulate filters.
GAMMA SPECTROMETRY The following media are typically analyzed: gamma isotopic content; milk, water, charcoal cartridges, airborne particulate filters, biological material (which includes aquatic animals, plants, and terrestrial vegetation), and sediment or soil samples. Samples are prepared by various controlled methods (blending, drying, milling) in order to maximize the volume which can be analyzed, and to achieve sample homogeneity. In order to ensure the precision and accuracy of the gamma measurements, specific counting containers are used to load sample media in a reproducible manner. Sample spectra are collected via high purity germanium based gamma ray spectrometry detection systems. The gamma spectrometry software can account for baseline corrections, background peak interferences, and photopeak multiplet resolution. Detected photopeaks are identified using a comprehensive library, specifically tailored for environmental monitoring around nuclear power facilities. Typical counting times for gamma spectrometry analyses vary from 7,200 to 30,000 seconds.
Decay corrections are typically made from the time of count to the end of collection. Exceptions are as follows:
composite water samples, which may be decayed to the mid-point of sampling, and charcoal cartridges and air particulate composites, for which a "decay during sampling" calculation is included. All gamma spectrometry analyses account for decay during the counting interval.
Serial decay corrections are required for parent/daughter radionuclide relationships. Milk and water samples requiring analysis for Ba-140/La-140 are held for eight days after collection, before analysis, in order to allow most of the unsupported La-140 (present at the time of collection) to decay and in order for the La-140 to achieve transient equilibrium with Ba-140. The La-140 concentration is then calculated from the parent, Ba-140. The Nb-95 A-2
DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 concentration, however, is assumed to be unsupported, and is calculated independently of its parent Zr-95, as long as Zr-95 is not detected in the sample. If Zr-95 is detected, the supported Nb-95 is calculated and subtracted from the total Nb-95, to yield the unsupported Nb-95 concentration.
LOW LEVEL IODINE ANALYSIS The low required detection limit for 1-131 in milk and water samples can only be achieved by radiochemical separation and concentration of the iodine. Milk samples may be preserved with sodium bisulfate or refrigerated after collection and are treated as soon as they arrive at the Laboratory with formaldehyde and methimazole (if preservation was not performed in the field). Vegetation samples are treated with NAOH. A known amount of stable iodide is added to the sample to quantify the final recovery. When Iodine-131 activity is observed or anticipated, the original iodide content of the sample is also quantified via an Orion EA 940 Expandable Ion Analyzer. The technique for initially isolating the iodine in a sample depends on its biological or physical form.
Vegetation is leached with sodium hydroxide, baked to an ash, and filtered; the iodide is then confined on anion exchange resin. Soil is leached with sodium hydroxide, then filtered. Drinking water, estuary, river, and ground water is treated with bleach, then reduced using hydroxylamine hydrochloride and sodium bisulfite to convert any form of iodine to iodide which is then confined on anion exchange resin. Preserved milk undergoes anion exchange.
Now isolated, the sample's iodine content is ready to be oxidized to periodate by bleach, treated with nitric acid, then extracted in toluene, wherein it is reduced to elemental iodine by hydroxylamine hydrochloride, reduced to iodide by sodium bisulfite, and finally precipitated as cuprous iodide for I-13 1 measurement by beta-gamma coincidence counting.
The beta-gamma coincidence system combines a plastic scintillator beta detector and associated electronics with a well-type Na(l) gamma detector. The amplified outputs from the detector assemblies are processed by timing single channel analyzers (TSCA). The gamma TSCA is optimized for the full width at tenth maximum of the 364.5 keV gamma photon of I-131. The resulting signal from each TSCA is relayed to a coincidence analyzer. The beta transition and prompt 364.5 keV gamma transition from I-13 1 register a coincidence count. Beta gamma coincidence counting allows for a very low background since the system is optimized for I-131. A typical counting time for low level iodine analysis is two hundred minutes.
H-3 ANALYSIS The determination of tritium in environmental matrices basically involves a sample preparation step followed by distillation and analysis of the pure distillate by liquid scintillation spectrometry. The tritium counting efficiency is determined using an efficiency curve generated as a function of sample quench. A set of NIST traceable standards is used for calibration.
The sample preparation step may involve extracting H-3 from the matrix in the presence of NaOH and KMnO4 or in the presence of HCI and H202 and allowing for sufficient equilibration time so that a complete transposition of tritium with stable hydrogen has occurred.
A window is set on the multi-channel analyzer associated with the liquid scintillation counting system which is optimized for the tritium beta energy. Additional widows are also set and evaluated to ensure that the distilled samples are free of interferences. A typical counting time for H-3 analysis is fifteen minutes.

DC Cook Nuclear Plant Units I&2 Annual Radiological Environmental Operating Report 2002 SR-89/90 ANALYSIS The determination of Sr-89,90 in environmental media is achieved primarily by pre-concentration followed by separation and purification. Strontium is pre-concentrated as the carbonate (SrCO3). SrCO3 is dissolved in nitric acid and the solution containing pure Sr-89,90 is analyzed for total Sr using the Cerenkov counting technique. The chemical recovery for total Sr is determined using Sr-85 as an internal radio tracer. After yttrium(Y)-90 in-growth, Sr-90 is separated and the Y-90 fraction is analyzed by Cerenkov counting. The Cerenkov radiation, resulting from the interactions of the Sr-89 and Y-90 beta emissions in the liquid scintillation counter is detected and processed by the multi-channel analyzer. The concentrations of each strontium isotope are resolved mathematically based on the two measured results. A typical combined counting time for Sr-89,90 analysis is two hundred ten minutes.

DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 APPENDIX B LAND USE CENSUS FOR 2002 B-I
DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 2002 Land Use Census Assessment The Land Use Census is performed annually to identify significant changes in land usage in the area surrounding Cook Plant, which could affect exposure pathways. Any identified changes are evaluated to determine whether modifications should be made to the REMP or other related programs. The following is a summary of the results of the 2002 census.
Dair' Farm Survey (See Attachments land 2)
The dairy farm survey was performed to update the list of dairy farms located in the plant area (Berrien County), to identify the nearest animal whose milk is used for human consumption. The milk farm survey for the Cook Plant was conducted on September 24 through 27 and on September 30, 2002.
There were no changes in the dairy farm list from the Michigan Department of Agriculture between July 1, 2001 and July 1, 2002. No new dairy farms were located in the County during this year's door-to-door survey.
At the present time, there are four farms/residence with dairy animals used for milk consumption within eight miles of the plant (Shuler, Monroe, Glen-Troy, & John Warmbein). The REMP milk-sampling program remains in effect at this time.
Therefore the collection of monthly broadleaf samples (in lieu of milk samples) has been discontinued (per 12THP-6010.RPP.635 "Collection of Milk Samples").
The closest milk-producing animals (for human consumption) are milk cows at the Shuler & Son Farm located at 2791 Snow Road in Baroda.
Residential Survey From June 1, 2001 to June 1, 2002, three (3) residential building permits were issued for construction in Lake Township for sections 5, 6, 7, and 8. These sections border the Cook Plant property. None of the permits change which residence in each sector is closest to the Cook Plant. In addition, none of these permits were issued to the residences, which are the closest in each sector. Therefore, none of the construction permits will affect the Plant's radiological evaluation of residential households.
Grape and Broadleaf Survey In accordance with the Offsite Dose Calculation Manual PMP-6010-OSD-001 and 12-THP-6010.RPP.638 "Collection of Grape and Broadleaf Samples" vegetation sampling is performed in lieu of a garden census. Broadleaf sampling is performed to monitor for plant impact on the environment. The samples were obtained as close to the site boundary as possible in a land sector, with sample media, with the highest average deposition factor (D/Q). Control samples were also obtained in a less prevalent sector approximately 20 miles for the site boundary.. These locations were the B. Kunde vineyard at 3316 Linco Road in Stevensville, in the vicinity of well water sample station W-l, and the Eldridge residence at 6156 Fail Road in LaPorte, respectively. The analytical results for the grape and broadleaf samples obtained on September 12, 2002, were less than ODCM LLDs (60 Pico-curies/kg for Cs-134, Cs-137, and I-13 1).

DC Cook Nuclear Plant Units 1&2 Annual Radiological Environmental Operating Report 2002 APPENDIX C Quality Assurance Program C-I
DC Cook Nuclear Plant Units 1&2 Annual Radiological Environmnental Operating Report 2002 J
OUALITY ASSURANCE PROGRAM The quality assurance program at the Framatome ANP Environmental Laboratory (FANPEL) is designed to serve two overall purposes: 1) Establish a measure of confidence in the measurement process to assure the licensee, regulatory agencies and the public that analytical results are accurate and precise; and 2) Identify deficiencies in the sampling and/or measurement process to those responsible for these operations so that corrective action can be taken. Quality assurance is applied to all steps of the measurement process, including the collection, measurement and reporting of data, as well as the record keeping of the final results. Quality control, as part of the quality assurance program, provides a means to control and measure the characteristics of the measurement equipment and processes, relative to established requirements.
The FANPEL employs a comprehensive quality assurance program designed to monitor the quality of analytical processing to ensure reliable environmental monitoring data. The program includes the use of controlled procedures for all work activities, a nonconformance and corrective action tracking system, systematic internal audits, audits by external groups, a laboratory quality control program, and a staff training program. Monitoring programs include the Intralaboratory Quality Control Program administered by the Laboratory QA Officer (used in conjunction with the National Institute of Standards and Technology Measurement Assurance Program, NIST MAP) and a third party cross check program administered by Analytics, Inc. Together these programs are targeted to supply QC/QA sources at 5% of the client sample analysis load. In addition the Laboratory Quality Control Audit Committee administers a blind duplicate program conducted through client environmental monitoring programs.
This summary reports all interlaboratory and third party results received by FANPEL on or before December 31, 2002.
Quality Assurance sample results that were not available for inclusion in this report will be evaluated and reported in accordance with DC Cook Plant procedures.
Intralaboratorv Oualitv Control Program The FANPEL QA Officer administers an extensive intralaboratory quality control program in which process check samples are submitted for analysis. These samples are submitted either in duplicate to evaluate the precision of a measurement process or are "spiked" with a known amount of radioactive material to assess the bias in the measurement.
Table C.1 provides the summary of the process check results for January to December 2002. Of the 510 analyses, 99.2%
passed the bias criteria and 97.4% of the results evaluated for precision were acceptable.
Third Party Cross Check Program The FANPEL participates in a third party cross check program managed by Analytics Inc. to satisfy the requirement of the Environmental Technical SpecificationlODCM. The FANPEL Analytics program was originally used to augment the EPA Intercomparison Program that it now replaces. The current program is designed to be comparable to the pre-1996 EPA PE Program in terms of the number of samples, matrices and nuclides. The results for the 4th quarter 2001 through the 3Yd quarter 2002 are summarized in Table C.2. Each sample is analyzed in triplicate and the results are evaluated against the internal acceptance criteria described in the FANPEL Manual 100-Laboratory Quality Assurance Plan. This acceptance protocol is used for all interlaboratory programs with no pre-set acceptance criteria. When results fall outside of the acceptance criteria, an investigation is initiated to determine the cause of the problem and if appropriate, corrective measures are taken. The FANPEL internal acceptance criteria are summarized at the end of Table C.2.

DC Cook Nuclear Plant Units 1 &2 Annual Radiological Environmental Operating Report 2002 Environmental TLD Ouality Assurance Program Performance documentation of the routine processing of the Panasonic environmental TLDs (thermoluminescent dosimeter) program at the FANPEL is provided by the dosimetry quality assurance testing program. This program includes the National Voluntary Laboratory Accreditation Program, independent third party performance testing by Battelle Pacific Northwest Labs and internal performance testing conducted by the Laboratory QA Officer. Under these programs, dosimeters are irradiated to ANSI specified testing criteria and submitted for processing to the Dosimetry Services Group as "unknowns". The bias and precision of TLD processing is measured against this standard and is used to indicate trends and changes in performance. Instrumentation checks, although routinely performed by the Dosimetry Services Group and representing between 5-10% of the TLDs processed, are not presented in this report because they do not represent a true process check sample since the doses are known to the processor.
Eighty-four performance tests were conducted in 2002 by FANPEL and the third party tester. Of these, 100% of the dosimeter evaluations met the FANPEL Internal Acceptance Criteria for bias (+/- 20.1%) and precision (+/-12.8%). In addition 14 TLD test sets passed the control limits set by the LQCAC in 1998 to evaluate the sum of the bias and precision values. A tolerance limit of +/- 30% applies to environmental dosimeters. Third Party QC results are summarized below.
