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, 2009. 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.
The Duane Arnold Energy Center (DAEC) is a boiling water reactor, located in Linn County, Iowa, on the Cedar River, and owned and operated by NextEra Energy Resources. 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 2009 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 is indicated in the areas surrounding the site of the Duane Arnold Energy Center.

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 provide a comparison between levels of naturally occurring radionuclides and radionuclides that could be attributed to the operation of the plant.
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 Pro-gram 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 nine locations. Airborne iodine is collected by continuous pumping through charcoal filters.
Eight of the nine locations are indicators and one is a control (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 filter samples are analyzed weekly for iodine-1 31.
Ambient gamma radiation is monitored at a total of 46 locations. A TLD is placed at each location and is exchanged and analyzed quarterly. The TLD locations are distributed as follows:
Eight at active air sampling stations.
a Four at de-activated air sampling stations greater than 3 miles from the DAEC stack.
Eighteen in a circle within a 0.5 mi. radius from the DAEC stack.
Six in 22.50 sectors within 1 mi. from the DAEC stack.
Ten in 22.50 sectors between 1 and 3 miles from the DAEC stack.
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 one indicator and one control location during the non-grazing season, October through April, and biweekly during the grazing season, May 1 through September 30.
The 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 nine locations: one control (D-108) and eight indicators (D-16, D-57, D-58, D-72, D-94, D-96, D-109 and D-118). Grain, hay and broad leaf (green leafy) vegetation samples are analyzed for gamma-emitting isotopes and at least two broad leaf vegetation samples are analyzed for iodine-131. An alternative site for broadleaf vegetation (D-15, indicator) may be sampled, if available.
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.
Potable ground water is collected quarterly from a treated municipal water system (D-53), the inlet to the municipal water treatment system (D-54), three indicator locations (D-55, D-57, D-58) and one control location (D-72). Non-potable water is collected from six on-site monitoring wells (MW-01 to MW-06).Two wells at each site, shallow (A) and intermediate (B) depths, have been made part of the permanent program. The samples are analyzed for gross beta and tritium.
If gross beta activity exceeds ten times the yearly mean of the control samples (or 7 pCi/liter), gamma isotopic, strontium-89 and strontium-90 analyses are performed.
Soil samples are collected once per year at two indicator locations (D-15a and D-16). The samples are analyzed for strontium-90, tritium and gamma-emitting isotopes.
4
Program Description (continued)
Surface water is collected monthly from four river locations, D-49 (Lewis Access, Control, 4 mi.
upstream), D-50 (Inlet), D-51 (Discharge) and D-61 (1/2 mi. downstream of discharge. In addition, Pleasant Creek Lake (D-99) surface water and sewage effluent from location (D-107) is also monitored. The monthly samples are analyzed for tritium and gamma-emitting isotopes. Additional analyses are performed on samples collected from the control and indicator locations, D-49 and D-61.
Analyses for low-level iodine-131 are performed on monthly collections and quarterly composites are prepared and analyzed for strontium-89 and strontium-90.
The aquatic environment is also monitored by upstream and downstream (D-49 and D-61) semiannual collections of fish. River bottom sediment is collected semiannually at the plant's intake and discharge (D-50 and D-51) and downstream of the sewage plant (D-107a). 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.
(1) Airborne Particulates / Airborne Iodine:
Air particulate / air iodine samples were collected later than scheduled for locations D-15 and D-16 for the weeks ending January 15, 2009. The stations were not accessible due to heavy snow accumulation. A collection was made on January 18, 2009.
A partial sample (176 m3) was collected from location D-15 for the week ending June 10, 2009, due to power loss.
(2) Surface Water:
Surface water could not be sampled for the January 27, 2009 collection, from locations D-49 and D-99.The water was frozen.
(3) Vegetation:
Strawberries were not available from location D-1 17. The crop was destroyed during the flooding of 2008 and not replanted in 2009.
Broadleaf vegetation samples were not available from location D-94 in 2009. An additional broadleaf vegetation sample was collected from location D-15 for 2009.
(4) Corrections to the 2008 Annual Report.
- a. Table 21, Part II. Soil was collected from site D-15a, not at site D-15, as listed in the report.
- b. Only one species of fish was collected from location D-49, June 27, 2008. The program description calls for two species.
- c. Groundwater samples from locations MW-04A, MW-06A, MW-06B were collected on 11-19-2008 and not on 11-24-2008 as listed in the report.

Program Execution, Corrections to the 2008 Annual Report. (continued)
- d. For 2008, Zn-65 was not listed with the gamma isotopic data for air particulate composites, hay, grain, and broadleaf vegetation samples. No Zn-65 was detected.
All air particulate composite samples measured below an LLD value of 0.0026 pCi/mi3.
All hay and grain samples measured below an LLD value of 0.061 pCi/g wet.
All broadleaf vegetation samples measured below an LLD value of 0.065 pCi/g wet.
- e. Even though the required LLDs for iodine-131 were met, the October, 2008 milk samples were not analyzed within the required time frame (8 days).
3.4 Laboratory Procedures The Iodine-131 analyses in milk and water were made using a sensitive radiochemical procedure involving separation of iodine using an ion-exchange method, solvent extraction and subsequent beta counting. Levels of iodine-131 in vegetation and concentrations of airborne iodine-131 in charcoal samples were determined by gamma spectroscopy.
Gamma-spectroscopic analyses is performed using a high-purity germanium (HPGe) detector. The gamma isotopic analysis provides a spectrum with an energy range from 80 to 2048 KeV. Levels of iodine-131 in vegetation and concentrations of airborne iodine-131 in charcoal samples are also determined by gamma spectroscopy.
Tritium was measured 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, 2009 ). The QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs. Results obtained in crosscheck programs are presented in Appendix A.
3.5 Program Modifications The sampling site D-1 17 (Vegetation, strawberries) was dropped from the program in 2009. A new location D-1 18 for broadleaf vegetation was added A new air particulate / air iodine station (D-40, Toddville) was added to the program, starting in the fourth quarter, 2009.
A requirement to analyze for radiostrontium and gamma emitters in groundwater was added in the fourth quarter, 2009. Samples will be analyzed for gamma isotopic, strontium-89 and strontium-90 if the gross beta activity exceeds ten times the yearly mean of the control samples, or 7 pCi/liter.

4.0 RESULTS AND DISCUSSION All collections and analyses were made as scheduled, except for those listed 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.
Tabulated results of measurements are not included in this section, although reference to these results will be made in discussion. A complete tabulation of results for 2009 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 2009.
4.2 Program Findings Results obtained show background levels of radioactivity in the environmental samples collected outside of the Site Protected Area in 2009.
Trace levels of cesium-1 37 are still detected in soil and sediment.
Strontium-90 is still measurable in soil and sediment samples.
The Sr-90 and Cs-1 37 activity is generally attributed to deposition of fallout from previous decades.
Tritium was identified in some groundwater samples collected within the site Protected Area. In no instances were REMP threshold reporting levels exceeded. (ODAM, Table 6.3-3)
Airborne Particulates The average annual gross beta concentrations in airborne particulates were similar at indicator and 3
control locations (0.031 and 0.030 pCi/m, respectively) and similar to levels observed from 1993 through 2008. The results are tabulated below.

4.2 Proqram Findinqs, Airborne Particulates (continued)
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, with an 3
average activity of 0.087 pCi/m for all locations. All other gamma-emitting isotopes were below their respective LLD limits.
Airborne Iodine 3
Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.030 pCi/m in all samples.
Ambient Radiation (TLDs)
At ten control locations, TLD readings averaged 18.2 mR/quarter. At locations within a half mile, one mile and stack, measurements averaged 20.2 mR/quarter, 19.3 mR/quarter and 18.2 mR/quarter, respectively. The two on-site locations D-15 and D-16 averaged 18.3 mR/quarter. The average for all locations was 19.0 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 Precipitation from the on-site location D-16 was analyzed for tritium and gamma-emitting isotopes. No tritium activity was measured above the LLD of 160 pCi/L. No gamma-emitting isotopes were detected.
Milk Iodine-131 results were below the detection limit of 0.5 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 2009 show no radiological effects of plant operation.

4.2 Proaram Findinas (continued)
Ground Water (potable)
The annual mean for gross beta activity 5.1 pCi/L, similar to levels observed from 1991 through 2008.
The location with the highest mean was D-58, a farm 1.0 mile distant from the plant.
Tritium activity measured below the LLD of 161 pCi/L in all samples. No effect from plant operation is indicated.
Ground Water (Site Monitoring Wells)
Twelve on-site monitoring wells (six shallow and six intermediate depth) were sampled in 2009 and analyzed for gross beta and tritium.
The annual mean for gross beta activity in six intermediate depth wells measured 4.0 pCi/liter.
Measurements for the shallow wells averaged 5.0 pCi/liter. The highest mean (6.7 pCi/L) was observed at shallow well MW-6A. The same pattern of concentration was observed in 2008. The most likely cause of higher beta activity is contribution from naturally-occurring isotopes. No plant effect was indicated.
Tritium activity measured below the LLD of 170 pCi/L in all twenty four samples collected from the intermediate depth wells. Activity was identified in seven of the twenty-four samples taken from the shallow wells and ranged from 180 to 3905 pCi!L. The highest mean (1360 pCi/L) was observed at shallow well MW-IA. The lower concentrations observed in 2008 may have been due to a dilutive effect from heavy flooding in the area. The activity has been attributed to "washout" from gaseous effluents.
Vegetation Iodine-1 31 concentrations in broadleaf vegetation were below the LLD level of 0.039 pCi/g wet weight in all samples.
With the exception of potassium-40, which was observed in all vegetation samples (broadleaf, grain, and forage), all other gamma-emitting isotopes were below detection limits. No effect from plant operation is indicated.
Soil Strontium-90 activity measured 0.022 pCi/g dry weight in one of the two on-site locations. Cesium-1 37 activity averaged 0.15 pCi/g dry weight for the two on-site locations. Strontium-90 and cesium-137 activities are similar or less than levels observed from 1991 through 2008, these levels are generally attributable to deposition of fallout from previous decades.
Naturally-occurring potassium-40 averaged 12.66 pCi/g dry weight. No effect from the plant operation is indicated.
The soil samples were distilled and analyzed for tritium. No tritium was detected above an LLD value of 189 pCi/L.

Procaram Findincqs (continued)
Surface Water Surface water was tested for tritium and gamma emitting isotopes in seventy samples from six locations. No measurable tritium activity was detected above an LLD of 168 pCi/L. Gamma-emitting isotopes were below detection limits.
An analysis for 1-131 was performed on samples from locations D-49 (control) and D-61 (0.5 mi.
downstream, indicator). All samples tested below detection limits.
Quarterly composites were also prepared from the samples collected at locations D-49 and D-61 and tested for strontium-89 and strontium-90. All samples tested below detection limits.
No plant effect on surface water is indicated.
Fish Fish were collected in June and September, 2009, and analyzed for gamma-emitting isotopes. With the exception of naturally-occurring potassium-40 no gamma-emitting isotopes were identified in edible portions of fish. The potassium-40 level was similar at both the indicator and control locations (2.98 and 3.17 pCi/g wet, respectively). No plant effect on the fish population is indicated.
River Sediments River sediments were collected in June and September, 2009, and analyzed for gamma-emitting isotopes. Potassium-40 activity ranged from 6.95 - 11.79 pCi/g dry weight and averaged 9.12 pCi/g dry weight.
Cs-137 activity was detected in one of two samples from the control location D-51 at a level of 0.12 pCi/g dry. Cesium-1 37 activities are similar or less than levels observed from 1991 through 2008, these levels are generally attributable to deposition of fallout from previous decades.
All other gamma-emitting isotopes were below detection limits. There is no indication of a plant effect.
4.3 Supplementary Groundwater Testingq There were no additional/ancillary samples collected in 2009 in support of the Nuclear Industry Ground Water Protection Initiative.
There were no REMP sample analyses results that warranted communications to State and Local Stakeholders.

Appendix A Interlaboratory Comparison Program Results Environmental, Inc., 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 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.
Table A-2 lists results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.
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.
Table A-5 lists REMP specific analytical results from 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.
Complete analytical data for duplicate analyses is available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
Results in Table A-7 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 Environmental Measurement Laboratory Quality Assessment Program (EML).
Attachment A lists the laboratory precision at the 1 sigma level for various analyses. The acceptance criteria in Table A-3 is set at +/- 2 sigma.
Out-of-limit results are explained directly below the result.

APPENDIX B DATA REPORTING CONVENTIONS B-1
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 = 2a 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 4.66a uncertainty for a background sample.
3.0. Duplicate analyses If duplicate analyses are reported, the convention is as follows.
3.1 Individual results: For two analysis results; x1 + s1 and x2 +/- s2 Reported result:
x +/- s; where x = (1/2) (x1 + x2) and s = (1/2) sl +S2 3.2.
Individual results:
< L1 I < L2 Reported result: < L, where L = lower of L1 and L2 3.3.
Individual results:
x +/- s, < L Reported result:
x +/- s if x a L; < 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 x, x2... xn are defined as follows:
1 x 2 X=
- 2-x n-I 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 2008 was completed during September and of 2009. All milk animals, residences 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 2 2 nd, 2009 for water use downstream of the DAEC to Cedar Rapids. This survey identified no new usages of river water from previous surveys. Irrigation at the strawberry farm in Palo has been discontinues. Recreational fishing is the only identified food pathway use of Cedar River water between the DAEC and the City of Cedar Rapids eight miles down-river.
There were 77 vegetable gardens identified during the performance of the 2009 Census. This number is less than the number of gardens found in the 2008 survey by 7. The location of the nearest vegetable receptor changed in 2009.
The garden in sector towards the SW at 4318 Power Plant Road was not planted in 2009. The closest vegetable receptor for 2009 is located 1.1 miles towards the SSW at 4370 Comp Road.
There was one change in the observed milk animal locations within the 3 mile radius of the plant in the past year. A farm at 3426 StandLea Road discontinued goats in 2009.
The locations of the nearest residence for each sector remained the same as 2008. In 2009, only two new homes were constructed within three miles of the DAEC.
Since the last performance of the land use census, there have been no new drinking water wells drilled within a two mile radius of the site. There were no other new land use or water use activities that could affect the Site Hydrogeological Conceptual Model D-2
In accordance with the DAEC's Environmental Sampling Procedure ESP 4.4, "Land Use Census", no changes in land use were identified that would adversely affect the safe operation of the DAEC, or that would warrant an update of the DAEC Updated Final Safety Analysis Report (UFSAR). Examples of land use that would warrant an UFSAR update include new hazards near the DAEC such as new gas pipelines or new installations utilizing toxic gases.
NextEra Energy Resources, Duane Arnold has committed to compliance with NEI 07-07, "Nuclear Energy Institute's Industry Ground Water Protection Initiative:
Per NEI 07-07, the following information is presented:
- Per Objectives 2.2 and 2.4, there were no on-site leaks or spills that warranted notification of state or local officials or other local stakeholders.
" No radioactive reactor by-product material was identified in samples taken by the DAEC's Radiological Environmental Monitoring Program (REMP) above the threshold concentration levels for reporting.

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 dosimetry 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 2009 TLD results were evaluated with a paired difference statistical test.
The evaluation concluded that there were no significant differences in the TLD populations for the 0.5 mile, 1 mile and 3 mile TLD populations.
- 2. As stated in Part 1 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 liquid and gaseous effluent releases was calculated using the Meteorological Information and Dose Assessment System (MIDAS) computer program in accordance with the ODAM. The calculation methods follow those prescribed by Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I".
Following calculation of offsite doses, the appropriateness of REMP sampling station types and locations was reviewed. The current sampling scheme was determined to be more than adequate for the identified receptors.
Results of the MIDAS dose calculations are displayed below.
1.) The hypothetical maximally exposed organ due to liquid effluents was the liver of a child with an estimated dose equivalent of 0.00000456 mrem.
2.) The whole body dose equivalent to the hypothetical maximally exposed individual due to liquid effluents was 0.00000456 mrem.
3.) The maximum dose to air at the site boundary from noble gases released was 0.00381 mrad from gamma radiation at 936 meters towards the Northwest.
4.) The maximum dose to air at the site boundary from noble gases released was 0.00186 mrad beta radiation at 936 meters towards the Northwest.
5.) The whole body dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.0019 mrem, at 805 meters towards the West.
6.) The skin dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.0031 mrem, at 805 meters towards the West.

1.0 INTRODUCTION
The following constitutes a supplement to the Annual Report for the Radiological Environmental Monitoring Program conducted at the Duane Arnold Energy Center, Palo, Iowa in 2009. Results of completed analyses are presented in the attached tables.
For information regarding sampling locations, type and frequency of collection, and sample codes, please refer to Part I, Tables 5.3 - 5.5 and Figures 5.1 and 5.2.
All concentrations, except gross beta and airborne iodine, are decay corrected to the time of collection. Airborne 1-131 is decayed to the midpoint of the collection period.
The required values for lower limits of detection (LLD) for gamma emitting isotopes are established through the Offsite Dose Assessment Manual (ODAM). Naturally occurring radioisotopes, such as Be-7, K-40 and Ra daughters, are frequently detected, but may not be listed for every sample medium.
