1.0 INTRODUCTION
This report summarizes and interprets results of the Radiological Environmental Monitoring Program conducted by Environmental, Inc., Midwest Laboratory at the Duane Arnold Energy Center, Palo, Iowa, during the period January -- December, 2002. This Program monitors the levels of radioactivity in the air, terrestrial, and aquatic environments in order to assess the impact of the Plant on its surroundings.-
Tabulation of the individual analyses made during the year are included in Part II of this report.
Duane Arnold Energy Center (DAEC) is located in Linn County, Iowa, on the Cedar River, owned by IES Utilities, Inc and operated by Nuclear Management Corporation. The Duane Arnold Energy Center is a 565.7 MW(e) boiling water reactor. Initial criticality was attained on March 23, 1974. The reactor reached 100% power on August 12, 1974. Commercial operation began on February 1, 1975.

SUMMARY
The Radiological Environmental Monitoring Program, as required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Duane Arnold Energy Center, is herein described. Results for the year 2002 are summarized and discussed.
Program findings show background levels of radioactivity in the environmental samples collected in the vicinity of the Duane Arnold Energy Center.
No effect on the environment due to the operation of the Duane Arnold Energy Center is indicated.

3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 3.1 Program Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program at the Duane Arnold Energy Center (DAEC) is to assess the impact of the plant on its environment. For this purpose, samples are collected from the air, terrestrial, and aquatic environments and analyzed for radioactive content.
In addition, ambient gamma radiation levels are monitored by thermoluminescent dosimeters (TLDs).
Sources of environmental radiation include the following:
(1)
Natural background radiation arising from cosmic rays and primordial radionuclides; (2)
Fallout from atmospheric nuclear detonations; (3)
Releases from nuclear power plants; and (4)
Industrial and medical radioactive waste.
In interpreting the data, effects due to the DAEC operation must be distinguished from those due to other sources.
A major interpretive aid in assessment of these effects is the design of the monitoring program at the DAEC which is based on the indicator-control concept. Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream). A station effect would be indicated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.
An additional interpretive technique involves analyses for specific radionuclides present in the environmental samples collected from the DAEC site. The DAEC's monitoring program includes analyses for strontium-90 and iodine-131, which are fission products, and tritium, which is produced by cosmic rays, atmospheric nuclear detonations, and also by nuclear power plants.
Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified: zirconium-95, cesium-137, and cerium-144. These three gamma-emitting isotopes were selected as radiological impact indicators because of the different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation. Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about 10% of the total activity of fission products ten (10) days after reactor shutdown. On the other hand, ten (10) days after a nuclear explosion, the contributions of zirconium-95, cerium-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud,1963). The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, barium-lanthanum-140, and cerium-141. These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the next group, manganese-54, cobalt-58 and-60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of nuclear power plant effluents, but are not produced in significant quantities by nuclear detonations. Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occurring isotope, were chosen as calibration monitors and should not be considered radiological impact indicators.

3.1 Program DesiQn and Data Interpretation (continued)
Characteristic properties of isotopes quantified in gamma-spectroscopic analysis are presented in Table 5.1. Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including those measured before the Plant became operational. Results of the DAEC's Monitoring Program can be related to those obtained in other parts of the world. Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations.
3.2 Program Description The sampling and analysis schedule for the environmental radiological monitoring program at the DAEC is summarized in Table 5.2 and is briefly reviewed below. Table 5.3 defines the sampling location codes used in Table 5.2 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the reactor site. The types of samples collected at each location and the frequency of collections are presented in Table 5 4 using codes defined in Table 5.5.
To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at twelve locations. Also, airborne iodine is collected by'continuous pumping through charcoal filters at six of these locations. Nine of the twelve locations are indicators and three are controls (D-1, D-2, and D-13). Filters are changed and counted weekly. Particulate filters are analyzed for gross beta activity. If gross beta activity exceeds ten times the yearly mean of the control samples, gamma isotopic analysis is performed. Quarterly composites of airborne particulates from each location are analyzed for gamma emitting isotopes.
- Charcoal filters are analyzed weekly for iodine-131 on all samples.
Ambient gamma radiation is monitored at twelve air sampling locations. In addition, gamma radiation is monitored at thirty-four special locations: eighteen in a circle within a 0.5 mi. radius of the DAEC stack; six in 22.50 sectors within 1 mi of the DAEC stack; and ten in 22.50 sectors between 1 and 3 miles of the DAEC stack. Two TLDs are placed at each location and are exchanged and analyzed quarterly.
Precipitation is collected monthly from one location and analyzed for gamma-emitting isotopes.
Quarterly composites are analyzed for tritium.
Milk samples are collected monthly from three locations during the non-grazing season, October through April, and biweekly during the grazing season, May 1 through September 30.
One location is a control (D-108) and the rest are indicators. All samples are analyzed for iodine-131 and gamma-emitting isotopes.
For additional monitoring of the terrestrial environment, grain, hay and broad leaf vegetation samples are collected annually, as available, from seven locations: one control (D-108) and six indicators (D-16, D-57, D-58, D-72, D-94, and D-96). Grain, hay and broad leaf (green leafy) vegetation samples are analyzed for gamma-emitting isotopes and at least one broad leaf vegetation is analyzed for iodine-131. If cattle are slaughtered for home use, a meat sample is collected annually, during or immediately following a grazing period from animals grazing on-site.
The sample is analyzed for gamma-emitting isotopes. Also, potable ground water is collected quarterly from a treated municipal water system (D-53), the inlet to the municipal water treatment system (D-54) and four additional ground water locations (D-55, D-57, D-58, and D-72). The samples are analyzed for gross beta and tritium.
If gross beta activity exceeds ten times the yearly mean of the control samples, gamma isotopic, strontium-89 and strontium-90 analyses are performed.

Program Description (continued)
Soil samples are collected once per year at two indicator locations (D-15 and D-16). The samples are analyzed for strontium-90 and gamma-emitting isotopes.
Surface water is collected monthly from five river, pond and sewage effluent locations, one control (D-49) and four indicator (D-50, D-51, D-99, and D-107). All monthly samples are analyzed for gamma-emitting isotopes. Tritium analyses are performed on quarterly composites from each location. In addition, all samples from Location D-107 (plant sewage discharge) are analyzed for potassium-40 by flame photometry.
The aquatic environment is also monitored by upstream and downstream (D-49 and D-61) semiannual collections of fish. River bottom sediment is also collected semiannually at the plant's intake and discharge (D-50 and D-51) and downstream of the sewage plant (D-107). The samples are analyzed for gamma-emitting isotopes.
3.3 Program Execution The program was executed as described in the preceding section with the following exceptions.
In no instance did missed analyses affect minimum sampling requirements as specified in the ODAM.

3.4 LaboratorV Procedures The iodine-131 analyses in milk were made using a sensitive radiochemical procedure involving separation of the iodine using an ion-exchange method, solvent extraction and subsequent beta counting.
Gamma-spectroscopic analyses were performed with HPGe detectors. Levels of iodine-131 in vegetation were determined by gamma spectroscopy. Concentrations of airborne iodine-131 in charcoal samples were also determined by gamma spectroscopy.
Tritium was determined by liquid scintillation.
Analytical Procedures used by Environmental, Inc. are on file and are available for inspection.
Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't of Energy, Edition 28, 1997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water, 1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual, 1984.
Environmental, Inc., Midwest Laboratory has a comprehensive quality control/quality assurance program designed to assure the reliability of data obtained.
Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2000 ). The QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs.
Results obtained in crosscheck programs are presented in Appendix A.
3.5 Program Modifications There were no program modifications for the year 2002.

4.0 RESULTS AND DISCUSSION All collections and analyses were made as scheduled, except for the listing in Table 5.6.
Results are summarized in Table 5.7 as recommended by the Nuclear Regulatory Commission: For each type of analysis and sample medium, the table lists the mean and range of all indicator and control locations, as well as that location with the highest mean and range.
The tabulated results of all measurements are not included in this section, although references to these results will be made in the discussion. A complete tabulation of results for 2002 is contained in Part II of the Annual Report on the Radiological Environmental Monitoring Program for the Duane Arnold Energy Center.
4.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests in 2002.
4.2 Program Findings Results obtained show background levels of radioactivity in the environmental samples collected in 2002.
Airborne Particulates The average annual gross beta concentrations in airborne particulates were identical at both indicator and control locations (0.027 pCi~m3) and similar to levels observed from 1987 through 2001. The results are tabulated below.
Year Indicators Controls Year Indicators Controls Concentration ( pCi/m 3)

Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation (Arnold and AI-Salih, 1955), was detected in all samples.
All other gamma-emitting isotopes were below their respective LLD limits. No effect from plant operation is indicated.
7
Airborne Iodine Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m3 in all samples.
Ambient Radiation (TLDs)
At twelve air sampling locations, the TLD readings averaged 17.2 and 15.7 mR/quarter for indicator and control locations, respectively. At locations within a half mile, one mile and three mile radius of the stack, measurements averaged 19.0 mR/quarter, 20.1 mR/quarter and 16.7 mR/quarter, respectively. The average for all locations was 18.1 mR/quarter. This is lower than the estimated average natural background radiation for Middle America, 19.5 mR/quarter, which is based on data on Pages 71 and 108 of the report, "Natural Background Radiation in the United States" (National Council on Radiation Protection and Measurements, 1975).
The terrestrial absorbed dose (uncorrected for structural and body shielding) ranges from 8 8 to 18.8 mrad/quarter and averages 11.5 mrad/quarter for Middle America.
Cosmic radiation and cosmogenic radionuclides contribute 8 0 mrad/quarter for a total average of 19.5 mrad/quarter.
No plant effect is indicated.
Precipitation In precipitation, the tritium concentration was below the LLD of 330 pCi/L in all samples. No gamma-emitting isotopes were detected. No plant effect is indicated.
Milk lodine-131 results were below the detection limit of 1.0 pCI/L in all samples.
No gamma-emitting isotopes, except naturally occurring potassium-40, were detected in any milk samples. This is consistent with the finding of the National Center for Radiological Health that most radiocontaminants in feed do not find their way into milk due to the selective metabolism of the cow. The common exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health, 1968)
In summary, milk data for 2002 show no radiological effects of plant operation.
Ground Water The annual mean for gross beta activity measured 3.2 pCi/L and was similar to levels observed from 1987 through 2001. The location with the highest mean (5.3 pCi/L) was D-58, a farm 1.0 mile distant from the plant. Tritium activity measured below the LLD of 330 pCi/L in all samples.
No effect from plant operation is indicated.
Vegetation Iodine-131 concentrations in broadleaf vegetation were below the LLD level of 0 033 pCi/g wet weight in all samples.
Except for potassium-40, which was observed in all vegetation samples ( broadleaf, grain, and forage ), all other gamma-emitting isotopes were below detection limits in all samples No effect from plant operation is indicated.
8
Soil Strontium-90 was detected in one sample from location D-15 and measured 0.044 pCig dry weight. Cesium-137 activity averaged 0.18 pCig dry weight. Both strontium-90 and cesium-137 activities are similar to or less than levels observed from 1987 through 2001, these levels are generally attributable to deposition of fallout from previous decades.
Naturally-occurring potassium-40 averaged 11.56 pCi/g dry weight. No effect from plant operation is indicated.
Surface Water Concentrations of tritium measured below the LLD level of 330 pCi/L in all samples. All gamma-emitting isotopes were below their respective LLDs.
Potassium-40 was measured at one location, D-107 (sewage effluent). The concentration ranged from 10.3 to 31.3 pCiL and averaged 21.6 pCi/L.
No plant effect on surface water is indicated.
Fish All gamma-emitting isotopes, except naturally-occurring potassium-40, in edible portions were below detection limits. The potassium-40 level was similar at both indicator and control locations (3.16 and 3.03 pCig wet, respectively). No plant effect on fish is indicated.
River Sediments River sediments were collected in May and September, 2002, and analyzed for gamma-emitting isotopes. Co-60 was detected in one sample from location D-107 (sewage effluent) at a concentration of 0.046 pCi/g dry weight. Cesium-137 measured below detection levels in all samples. Potassium-40 activity ranged from 5.74-9.31 pCi/g dry weight and averaged 7.52 pCi/g dry weight.
All other gamma-emitting isotopes were below detection limits.

APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE:
Environmental Inc., Midwest Laboratory participates in intercomparison studies administered by Environmental Resources Associates, and serves as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.
January, 2002 through December, 2002
Appendix A Interlaboratorv Comparison Program Results Environmental, Inc.. Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.
Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.
Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.
The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. Results of internal laboratory testing is also listed.
Table A-3 lists results of the analyses on in-house 'spiked' samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house 'blank" samples for the past twelve months. Data for previous years available upon request. request.
Table A-5 list results of the in-house 'duplicate' program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.
2.0. Single Measurements Each single measurement is reported as follows:
x +/- s where:
x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.
3.0. Duplicate analyses 3.1 Individual results: For two analysis results; xj+/- sl and X2 S2 Reported result:
x + s; where x = (1/2) (x1 + x2) and s = (1/2)
SI +
3.2.
Individual results-
<LI, <2 Reported result: <L, where L = lower of LI and L2 3.3.
Individual results-x +/- s, <L Reported result:
x +/- s if x zal-; <L otherwise.
4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x1, x2... Xn are defined as follows:
xj SXn-Xn nx s1 4.2 Values below the highest lower limit of detection are not included in the average.
4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.
4.5 In rounding off, the following rules are followed.
4.5.1. If the number following those to be retained is less than 5, the number is dropped, and the retained numbers are kept unchanged. As an example, 11.443 is rounded off to 11.44.
4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 11.445 is rounded off to 11.45.

SUMMARY
OF THE LAND USE CENSUS D-1
Appendix D Summary of the Land Use Census The Duane Arnold Energy Land Use Census for 2002 was completed during the third week of September 2002. All milk animals and gardens greater than 500 square feet were identified within three miles for each of the 16 meteorological sectors. If none were identified within the three mile range, additional surveys were performed out to a distance of five miles. The Cedar River was surveyed by boat on July 17th, 2002 for water use downstream of the DAEC to Cedar Rapids.
There were 178 gardens found during the performance of the 2002 Census. This number exceeds the number of gardens found in the 2001 survey by 7. This difference can be attributed to the removal of 12 gardens and the addition of 19 new gardens.
There were no changes in the milk animal locations in the past year.
The locations of the nearest resident for each sector remained the same in 2002.
37 new homes were built or were under construction within three miles of the DAEC, compared to the 31 new homes identified in 2001. Most of the new houses built were located in the sectors between the plant, Palo and Cedar Rapids (SSW to SE).
In an effort to increase the precision of the recorded location of receptors in relation to the DAEC, a hand held Global Positioning System (GPS) was used to more accurately describe the location of receptors.
The Cedar River survey revealed no new withdrawals of river water compared to previous surveys. Irrigation of the strawberry farm in Palo and fishing remain the only food pathway uses of river water between the DAEC and Cedar Rapids.
As a result of this census, adjustments were made to the MIDAS dose projection software model for changes in vegetation receptors and the more precise receptor distances.
Pursuant to ESP4.4, no changes were observed offsite that could adversely affect the safe operation of the DAEC or that would warrant a UFSAR update such as new gas pipelines, toxic gas installations or airfield strips.

APPENDIX E ANNUAL RADIATION DOSE ASSESSMENT E-1
Appendix E Annual Radiation Dose Assessment The annual offsite radiation dose to a member of the public was determined by assessment of environmental dosimeter results and by calculations based on monitored effluent releases.
Section A.
Dose Contribution from Direct Radiation Direct radiation dose from the operation of the DAEC was reported by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM).
- 1. Pre-operational and 2002 TLD results were compared using a paired difference test. No significant differences in the TLD populations were observed for the 0.5 mile and one mile TLD populations using a confidence level of 99%.
- 2. As stated in Part 1, page 8 of this report, no plant effect was indicated by the TLDs when dose results were compared to the estimated average natural background for Middle America.
Section B.
Estimated Offsite Dose from Effluent Releases The contribution of dose to a member of the public most likely to be exposed from effluent releases was calculated by the Meteorological Information and Dose Assessment System (MIDAS) computer program in accordance with ODAM. The calculation methods follow those prescribed by Reg. Guide 1.109. Because there were no nuclides detected in the environment at or beyond the site boundary that were due to the operation of the DAEC, no comparison of calculated dose from stack releases and dose calculated from environmental contamination was performed.
1.) There were no releases of radioactive material to liquid effluents in 2002.
2.) The maximum dose to air at the site boundary from noble gases released was 2.8E-03 mrad from gamma radiation at 535 meters SSW.
3.) The maximum dose to air at the site boundary from noble gases released was 3.9E-02 mrad beta radiation at 535 meters SSW.
4.) The whole body dose equivalent to the maximally exposed individual from noble gases was 1.5E-03 mrem, at 805 meters West.
5.) The skin dose equivalent to the maximally exposed individual from noble gases was 2.OE-03 mrem, at 1620 meters NNW.
6.) The maximally exposed organ due to iodines and particulates with half-lives greater than eight days was the liver of a child at 1620 meters NNW, with an estimated dose equivalent of 3.4E-03 mrem.

==
Conclusion:==
No measurable dose due to the operation of the DAEC was detected by environmental TLDs in 2002. The calculated doses are below the regulatory limits stated in Appendix I to 10 CFR 50 and in 40 CFR 190.
