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, 2011. 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.
Tabulations of 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. Nuclar Regulatory Commission (NRC) Technical Specifications for the Duane Arnold Energy Center, is herein described.
Results for the year 2011 are summarized and discussed.
Trace levels of tritium in groundwater were reported from the sampling of monitoring wells within the Owner Controlled Area. REMP threshold reporting levels were not exceeded.
Program findings show only background levels of radioactivity in the environmental samples collected in the vicinity of the Duane Arnold Energy Center, with the exception of the period from March 24 through April 7, 2011.
The detection of airborne iodine-131 is consistent with and attributable to radioactive elements released from the Fukushima Daiichi reactors or fuel pools in the aftermath of the March 11, 2011 Japanese earthquake and tsunami.
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.

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 3.2.1 Environmental Monitoring The sampling and analysis schedule for the Radiological Environmental Monitoring Program (REMP) 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 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 50 locations. A TLD is placed at each location and exchanged and analyzed quarterly. The TLD locations are distributed as follows:
Two on-site locations Eighteen in a circle within a 0.5 mi. radius from the DAEC stack.
Six in 22.5' sectors within 1 mi. from the DAEC stack.
Ten in 22.50 sectors between 1 and 3 miles from the DAEC stack.
Ten control locations greater than 3 miles from the DAEC stack.
Four along sections of the Independent Spent Fuel Storage Installation (ISFSI) fenceline.
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 (downstream of Discharge) and also from Pleasant Creek Lake (D-99). 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.
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). The samples are analyzed for gross beta and tritium. If gross beta measures greater than 3 pCi/L, or positive tritium is detected, an analysis for gamma emitters is performed. If a gross beta measurement is greater than 7 pCi/L, or reactor by-product gamma emitters are detected, analyses for Fe-55, Sr-89, Sr-90, Ni-63 and alpha emitters are performed.

Proqram Description (continued)
Milk is 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-1 31 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-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.
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.
3.2.2 Groundwater Protection Non-potable water is collected from twelve on-site locations (MW-01 to MW-12). Two monitoring wells are sampled from each site, at shallow (A) and intermediate (B) depths, and analyzed for tritium. If the tritium concentration is greater than 1000 pCi/L, additional analyses for Sr-89, Sr-90, Fe-55, Ni-63, gross alpha and gamma-emitting isotopes are performed.
Precipitation is collected monthly from six on-site locations and analyzed for gamma-emitting isotopes. A quarterly composite is analyzed for tritium.
Soil samples are collected annually at the two on-site locations, D-15a and D-16. The samples are analyzed for strontium-90, tritium and 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:
A partial air particulate / air iodine sample (133 M3) was collected at location D-7, for the week ending 01/13/11. Sampler run-time reported for 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br />.
Partial air particulate / air iodine samples were collected at locations D-6, D-1 1 and D-1 3, for the week ending 05/12/11. Storms in the area caused power outages.
A partial air particulate / air iodine sample (268 M3) was collected at location D-6, for the week ending 06/09/11. Power shut off during electrical storms. No air particulate / air iodine sample was available from location D-6 for the week ending 06/16/11. There was still no power to the station.
Air particulate / air iodine samples were not available at location D-40, for the week ending 07/07/11. The sampler was out of service due to voltage supply problems.
A partial air particulate / air iodine sample (164 M3) was collected at location D-3, for the week ending 08/04/11. Run-time was reduced due to construction in area.
(2) Surface Water:
Surface water from location D-99 could not be sampled for the January 18, 2011 collection.
The lake was frozen.
(3) Thermoluminescent Dosimetry The second quarter, 2011 TLD at location D-37 was missing in the field. The TLD was replaced.
The third quarter TLD for location D-48 was not collected until the fourth quarter, 2011. The total exposure was 181 days, the data was prorated to a standard quarter.
(4) Well Water Samples from wells MW-01A, MW-03A, MW-05A, collected on July 30, 2011 and samples from wells MW-03A, MW-03B, MW-05A and MW-05B, collected on August 15, 2011 were lost in transit.

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 are performed using high-purity germanium (HPGe) detectors.
The gamma isotopic analysis provides a spectrum with an energy range from 80 to 2048 KeV.
Specific isotopes included in the gamma library are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. Naturally occurring gamma-emitters, such as Be-7, K-40 and Ra daughters, are frequently detected but may not be listed.
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 t'.a reliability of data obtained.
Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2011). The QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs.
Results obtained in crosscheck programs are presented in Appendix A.
3.5 Program Modifications Soil and precipitation sampling from onsite locations D-15a and D-16 was added to the Groundwater Protection Program. In addition, precipitation from five of the monitoring well locations (D-111, D-112, D-114, D-115 and D-116 are collected. The samples are analyzed for tritium and gamma emitting isotopes.
Six new pairs of on-site monitoring wells were added to the Ground Water Protection Program in 2011. The samples were analyzed for tritium. If the tritium concentration is greater than 1000 pCi/L, conditional analyses for gross alpha, gamma emitting isotopes, Fe-55, Ni-63, Sr-89 and Sr-90 are performed.
TLDs were placed along sections of the Independent Spent Fuel Storage Installation (ISFSI) fenceline. Four additional TLDS were added to the program in the second quarter of 2011.

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 2011 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 The Fukushima Daiichi nuclear accident occurred on March 11, 2011, releasing large amounts of radioactive isotopes into the atmosphere and Pacific Ocean. Positive iodine-131, cesium-1 34 and cesium-137 activities were detected in environmental background samples from March through May. The accident, rated seven on the International Nuclear Event Scale (INES) compares with Chernobyl, rated level seven, and Three Mile Island rated level five.
4.2 Program Findings Results obtained show background levels of radioactivity in the environmental samples collected outside of the Owner Controlled Area in 2011. The trace levels of strontium-90 and cesium-137, still measurable in soil and sediments are attributed to deposition of fallout from previous decades.
Tritium was identified in some groundwater samples collected within the Owner Controlled 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 almost identical at indicator and control locations (0.030 and 0.029 pCi/m 3, respectively) and similar to levels observed from 1995 through 2011. The results are tabulated below.
Year Indicators Controls Year Indicators Controls Concentration (pCi/m3)

4.2 Program Findings, 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 average activity of 0.071 pCi/m 3 for all locations. All other gamma-emitting isotopes were below their respective LLD limits.
Airborne Iodine Following the Fukushima Daiichi accident, measurable radioiodine was detected in weekly collections of activated charcoal cartridges. For the weeks ending March 24, March 31 and April 7,
- 2011, activity for all locations averaged 0.14, 0.076 and 0.082 pCi/m 3, respectively.
Measurements for the rest of the year were below the required limit of detection of 0.070 pCi/m3.
Ambient Radiation (TLDs)
At ten control locations, TLD readings averaged 16.5 mR/quarter. At locations within a half mile, one mile and three mile radius of the stack, the measurements averaged 18.1, 19.0 and 16.2 mR/quarter, respectively. The two on-site locations D-15 and D-16 averaged 16.9 mR/quarter. Four TLDS were added to the program in the second quarter of 2011. The TLDs, placed directionally along the ISFSI fenceline, averaged 15.0 mR/quarter. The average for all locations was 17.3 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 radiat!on and cosmogenic radionuclides contribute 8.0 mrad/quarter for a total average of 19.5 mrad/quarter. No plant effect is indicated.
Milk Iodine-1 31 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 2011 show no radiological effects of plant operation.
Ground Water (potable)
The annual mean for gross beta activity 2.6 pCi/L, similar to levels observed from 1991 through 2010. 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 151 pCi/L in all samples.
No effect from plant operation is indicated.
9
4.2 Progqram Findings (continued)
Vegetation Iodine-131 concentrations in broadleaf vegetation were below the LLD level of 0.037 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.
Surface Water Surface water was tested for tritium and gamma emitting isotopes in fifty-nine samples from five locations. No measurable tritium activity was detected above an LLD of 163 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 May and August, 2011, 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 (3.21 and 3.34 pCi/g wet, respectively). No plant effect on the fish population is indicated.
River Sediments River sediments were collected in June and November, 2011, and analyzed for gamma-emitting isotopes. Potassium-40 activity ranged from 5.43-10.74 pCi/g dry weight and averaged 8.33 pCi/g dry weight.
Cs-137 was detected at both indicator and control locations and averaged 0.037 and 0.10 pCi/g dry, respectively. The measurements are similar to levels observed from 1991 through 2010, trace cesium activity is 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.
10
4.3 Ground Water Protection Proaram There were no sample analyses results that warranted communications to State and Local Stakeholders.
Refer to Part II, Appendix A for results of additional/ancillary samples collected in support of the Nuclear Industry Ground Water Protection Initiative.
Soil Strontium-90 was detected at both indicator locations and averaged 0.033 pCi/g dry. Cesium-137 activity averaged 0.12 pCi/g dry weight. Strontium-90 and cesium-137 activities are similar or less than levels observed from 1991 through 2010, these levels are generally attributable to deposition of fallout from previous decades.
Naturally-occurring potassium-40 averaged 12.28 pCi/g dry weight. No effect from the plant operation is indicated.
The soil was distilled and analyzed for tritium. No tritium was detected above a background level of 150 pCi/L.
Ground Water (Site Monitoring Wel!s)
Twelve on-site monitor!ng wells (six shallow and six intermediate depth) were sampled in 2011 and analyzed for tritium. Twelve additional wells (six shallow and six intermediate depth) were added to the Ground Water Protection Program in 2011.
Tritium was detected in twenty-five of eighty-six samples tested, most activity was observed in samples taken from shallow wells. Measurements ranged from 2087 pCi/L to less than LLD. The highest average activity (1915 pCi/L) was measured in samples collected from the intermediate depth well, MW-08B.
Precipitation Precipitation from the on-site location D-1 6 and five monitoring well locations (D-1 11, D-1 12, D-114, D-1 15 and D-1 16) were collected. The samples were analyzed for tritium and gamma emitting isotopes.
Low levels of tritium were detected in fourteen of sixty-nine samples tested. The mean activity was 475 pCi/L, ranging from 186 to 1549 pCi/L.
Composite samples were prepared for locations D-111, 112, 114, 115 and D-116 and monthly samples from D-16 were analyzed by gamma spectroscopy. No gamma-emitting isotopes were detected.

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 through December, 2011
Appendix A Interlaboratory Comparison Progqram 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 interna: 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.

Laboratory codes as follows: STW (water), STAP (air filter), STSO (soil), STVE (vegetation).
MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP. A known value of "zero" indicates an analysis was included in the testing series as a "false positive". MAPEP does not provide control limits.
Result of a repeat analysis was still unacceptable. ERA crosschecks for Am-241 were acceptable, but biased low.
Matrix spikes were prepared, ( 5.17 and 51.7 pCi/L), to verify method; results were acceptable, 4.4 and 47.5 pCi/L.
Am-241 has been added to the internal spike and blank program for 2012.
f An error in percent recovery was found, result of recalculation, 427.3 +/- 18.8 Bq/kg dry.
9 No errors found in calculation or procedure, results of reanalysis; 1.73 Bq/filter.
h The analyses were repeated through a strontium column; mean result of triplicate analyses, 304.2 Bqtkg.
The lab does not currently analyze soil for Tc-99, but is evaluating the procedure. After consultation with Eichrom, the analysis was repeated using a matrix spike correction. Mean result of triplicate reanalyses; 183.3 Bq/kg.

APPENDIX B DATA REPORTING CONVENTIONS B-1
Data Reportinq 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 iower limit of detection based on 4.66cy 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) (xi + x2) ands= (1/2) 1s2 3.2.
Individual results:
< Li,
< L2 Recorted result: < L, where L = lower of Li and L2 3.3.
individual results:
x +/- s, < L Reported result:
x +/- s if x > 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 x1, x2... xn are defined as follows:
xn I x s=
n-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 2011 was completed during September and October of 2011. 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 September 9 th, 2011 for water use downstream of the DAEC to Cedar Rapids. This survey identified no new usages of river water from previous surveys. 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 114 vegetable gardens identified during the performance of the 2011 Census. This number is more than the number of gardens found in the 2010 survey by 39. The distance to the nearest vegetation receptor changed in one sector. In the sector towards the east-north-east, a new garden was identified at 2470 meters.
This is compares of a distance of 2790 meters in that sector in 2010. There were no other changes to the locations of the nearest vegetable receptors.
There were five new cattle herds observed and in one location, cattle were discontinued. Cattle were replaced by goats at another location. There was one other new goat heard detected. There were no observed changes in milk cow locations.
There were 2 instances where there was a change in the location of the nearest resident in each sector.
" In the sector towards the south, a house heavily damaged by the 2008 flood was demolished. The distance to the nearest resident in the sector changed from 2200 meters to 3800 meters.
" In the sector towards the south-south-east, a house heavily damaged by the 2008 flood was demolished. The distance to the nearest resident changed from 2380 meters to 3020 meters.
Since the last performance of the land use census, a new drinking water well has been identified within a two mile radius of the site. The well is located 3,200 meters D-2
towards the South East. The well is on the opposite side of the Cedar River and not hydrologically relevant to our site. There were no other new land use or water use activities that could affect the Site Hydrogeological Conceptual Model.
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 samp!es collected by the DAEC's Radiological Environmental Monitoring Program (REMP) or the site Ground Water Protection Program (GWPP) above the threshold concentration levels for reporting.
Errata to the 2009 Report The opening paragraph of Appendix D of the 2009 Annual Radiologica.]
Environmental Operating Report was incorrect, referencing 2008 rather than 2009.
The opening paragraph should have been:
The Duane Arnold Energy Land Use Census for 2009 was completed during September and October 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.

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 2011 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 and 1 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
- 1. 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".
- 2.
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.
There were no releases of radioactive material to liquid effluents in 2011.
- 2.
The maximum dose to air at the site boundary from noble gases released was 0.000225 mrad from gamma radiation at 481 meters towards the South-South-East.
- 3.
The maximum dose to air at the site boundary from noble gases released was 0.000041 mrad beta radiation at 2416 meters towards the East-North-East.
- 4.
The whole body dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.000260 mrem, at 805 meters towards the West.
- 5.
The skin dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.000270 mrem, at 805 meters towards the West.
- 6.
The hypothetical maximally exposed organ due to airborne iodines and particulates with half-lives greater than eight days was the thyroid of a child at 805 meters to the West, with an estimated dose equivalent of 0.00736 mrem.
- 7.
The hypothetical maximally exposed organ due to airborne carbon-14 was the bone of a child located 2.9 miles to the West-North-West of the site. The dose is 0.11 mrem.
E-2
Carbon14 The estimate of gaseous carbon-14 (C-14) released from the Duane Arnold Energy Center was derived using guidance from the EPRI document, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents", Report 1021106, issued December 2010. The total amount of C-14 released in 2011 was estimated to be 9.50 Curies.
Using the dose calculation methodology from Regulatory Guide 1.109, the resultant maximally exposed receptor organ from C-14 is the bone of a child, located 2.9 miles to the West-North-West of the site. The dose is 1.01 E-01 mrem. (0.11 mrem).
==
Conclusion:==
No measurable dose due to the operation of the DAEC was detected by environmental TLDs in 2011. The calculated doses are below the regulatory limits stated in Appendix I to 10 CFR 50 and in 40 CFR 190.

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 2011. 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.
