Attachment to 0CAN051001 Page 4 of 49 Summary The Annual Radiological Environmental Operating Report (AREOR) presents data obtained through analyses of environmental samples collected for Arkansas Nuclear One's (ANOs)
Radiological Environmental Monitoring Program (REMP) for the period January 1, 2009 through December 31, 2009. This report fulfills the requirements of ANO Unit 1 Technical Specification (TS) 5.6.2 and Unit 2 TS 6.6.2.
During 2009, as in previous years, ANO detected radionuclides attributable to plant operations at the discharge location (Station 8) where previously monitored liquid radioactive effluent from the plant is periodically discharged in accordance with the regulatory criteria established in the Offsite Dose Calculation Manual (ODCM). ANO personnel routinely monitor results from this area in order to note any trends. The review of results from this area indicates the following:
Tritium levels in the surface water media continue to be below regulatory reporting limits and are consistent with concentrations that would typically be seen at this location as discussed in Section 2.3 of this AREOR Gross beta concentrations at the Station 14 (City of Russellville) indicator drinking water location continue to remain consistent with previous operational measurements and similar to the levels detected at the Station 57 (City of Danville) control drinking water location.
Radiological Environmental Monitoring Program ANO established the REMP prior to the station becoming operational (1974) to provide data on background radiation and radioactivity normally present in the area. ANO has continued to monitor the environment by sampling air, water, sediment, fish and food products, as well as measuring radiation directly. ANO also samples milk if milk-producing animals are present commercially within five miles of the plant.
The REMP includes sampling indicator and control locations within an approximate 20-mile radius of the plant. The REMP utilizes indicator locations near the site to show any increases or buildup of radioactivity that might occur due to station operation, and control locations farther away from the site to indicate the presence of only naturally occurring radioactivity.
ANO personnel compare indicator results with control and preoperational results to assess any impact ANO operation might have had on the surrounding environment.
In 2009, ANO personnel collected environmental samples for radiological analysis. They compared results of indicator locations with control locations and previous studies and concluded that overall no significant relationship exists between ANO operation and effect on the plant environs. The review of 2009 data, in many cases, showed undetectable radiation levels in the environment and in all instances, no definable trends related to significant pathways associated with ANO.
Harmful Effects or Irreversible Damage The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in 2009. Therefore, no analysis or planned course of action to alleviate problems was necessary.
Attachment to 0CAN051001 Page 5 of 49 Reporting Levels ANO's review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples due to ANO effluents, as outlined in ODCM Table 2.6-3, when averaged over any calendar quarter. Therefore, 2009 results did not trigger any Radiological Monitoring Program Special Reports.
Radioactivity Not Attributable to ANO The ANO REMP has detected radioactivity attributable to other sources. These include the 25th Chinese nuclear test explosion in 1980 and the radioactivity plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant in 1986. Prior to 1981, the ANO REMP detected radioactivity resulting from nuclear weapons testing, with Cesium-137 continuing to be periodically detected.
Comparison to Federal and State Programs ANO personnel compared REMP data to state monitoring programs as results became available. Historically, the programs used for comparison have included the U.S. Nuclear Regulatory Commission (NRC) Thermoluminescent Dosimeter (TLD) Direct Radiation Monitoring Network and the Arkansas Department of Health (ADH).
The NRC TLD Network Program was discontinued in 1998. Historically these results have compared to those from the ANO REMP. ANO TLD results continue to remain similar to the historical average and continue to verify that plant operation is not affecting the ambient radiation levels in the environment.
The ADH and the ANO REMP entail similar radiological environmental monitoring program requirements. These programs include collecting air samples and splitting or sharing sample media such as water, sediment and fish. Both programs have obtained similar results over previous years.
Sample Deviations Milk The REMP did not include milk sampling within five miles (8 kilometers (km)) of ANO in 2009 due to unavailability. The ODCM requires collection of milk samples if available commercially within 8 km (5 miles) of the plant. ANO personnel collected vegetation samples to monitor the ingestion pathway, as specified in the ODCM, because of milk unavailability.
Required Lower Limit of Detection (LLD) Values LLDs during this reporting period were within the acceptable limits required by Table 2.6-2 of the ODCM.
Attachment to 0CAN051001 Page 6 of 49 Air Samples Listed below are air sampler deviations that occurred during 2009 due to hazardous weather conditions, electrical power outages and equipment failure. These deviations did not result in the exceedance of the LLD values specified in the ODCM. As described in footnote (a) to ODCM Table 2.6-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

Attachment to 0CAN051001 Page 7 of 49 1.0 Introduction 1.1 Radiological Environmental Monitoring Program ANO established the REMP to ensure that plant operating controls properly function to minimize any associated radiation endangerment to human health or the environment. The REMP is designed for:
Analyzing applicable pathways for anticipated types and quantities of radionuclides released into the environment.
Considering the possibility of a buildup of long-lived radionuclides in the environment and identifying physical and biological accumulations that may contribute to human exposures.
Considering the potential radiation exposure to plant and animal life in the environment surrounding ANO.
Correlating levels of radiation and radioactivity in the environment with radioactive releases from station operation.
1.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways are monitored as required by the ODCM. A description of the ANO REMP utilized to monitor the exposure pathways is described in Table 1.1 and shown in Figures 1-1, 1-2 and 1-3.
Section 2.0 of this report provides a discussion of 2009 sampling results and Section 3.0 provides a summary of results for the monitored exposure pathways.
1.3 Land Use Census ANO personnel conducts land use census biannually (once every two years) as required by ANO Units 1 and Unit 2 ODCM Section 2.6.2. The latest land use census was conducted in 2009. The purpose of this census is to identify changes in uses of land within five miles of ANO that would require modifications to the REMP or ODCM. The most important criteria during this census are to determine location in each sector of the nearest:
- 1) Residence
- 2) Animal milked for human consumption
- 3) Garden of greater than 500 square feet producing fresh leafy (broadleaf) vegetables *
- ANO personnel do not perform a garden census since ODCM Section 2.6.2 allows the routine sampling of broadleaf vegetation in the highest D/Q sector near the site boundary in lieu of the garden census.
Attachment to 0CAN051001 Page 8 of 49 The method used by ANO personnel for conducting the land use census is as follows:
ANO personnel conducted door-to-door (drive by) field surveys in order to locate the nearest resident in each meteorological sector.
Consultation with local agricultural authorities is used for the identification of commercial milk providers within five-miles of the Unit-1 reactor building.
As a result of these surveys, the following information is obtained in each meteorological sector:
- 1) Nearest permanent residence
- 2) Nearest milking animal ANO personnel identify locations on the map, measure distances to ANO (or use a global positioning system) and record results.
Locations, if any, are identified which yield a calculated dose or dose commitments greater than those currently calculated in the ODCM.
ANO personnel compare results to previous census.

Attachment to 0CAN051001 Page 18 of 49 2.0 Interpretation and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results The REMP has detected radioactivity in the airborne pathway attributable to other sources.
These include the 25th Chinese nuclear test explosion in 1980 and the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986.
During 2009, Iodine-131 was not detected in the radioiodine cartridges, as has been the case in previous years. In addition, indicator gross beta air particulate results for 2009 were within the range of levels obtained in previous years of the operational REMP and well below preoperational levels as seen below. The results below are reported as annual average picocuries per picocuries per cubic meter (pCi/m3).
Monitoring Period Result 2000 - 2008 (Minimum Value) 0.020 2009 Value 0.030 2000 - 2008 (Maximum Value) 0.032 Preoperational 0.050 In the absence of plant-related gamma radionuclides, gross beta activity is attributed to naturally occurring radionuclides. Table 3.1, which includes gross beta concentrations and provide a comparison of the indicator and control means and ranges, emphasizes the consistent trends seen in this pathway to support the presence of naturally occurring activity.
Therefore, it can be concluded that the airborne pathway continues to be unaffected by ANO operations.
2.2 TLD Sample Results ANO reports measured dose as net exposure (field reading less transit reading) normalized to 92 days and relies on comparison of the indicator locations to the control as a measure of plant impact. ANOs comparison of the inner ring and special interest area TLD results to the control, as seen in Table 3.1, identified no noticeable trend that would indicate that the ambient radiation levels are being affected by plant operations. In addition, the inner ring value of 8.3 millirem (mrem) shown in Table 3.1 is within the historical bounds of 2000 - 2008 annual average results, which have ranged from 6.7 to 8.8 mrem.
Overall, ANO concluded that the ambient radiation levels are not being affected by plant operations.
2.3 Water Sample Results Analytical results for 2009 surface water and drinking water samples were similar to those reported in previous years.
Attachment to 0CAN051001 Page 19 of 49 Surface water samples were collected and analyzed for gamma radionuclides and tritium.
Gamma radionuclides were below detectable limits which is consistent with results seen in previous operational years. Tritium continues to be detected at the indicator location (Station 8) where previously monitored liquid radioactive effluent from the plant is periodically discharged in accordance with the regulatory criteria established in the ODCM. However, the levels detected are consistent with concentrations that would typically be seen at this location as shown below. The results below are reported as annual average picocurie per liter (pCi/l).
Monitoring Period Concentration 2000 - 2008 (Minimum Value) 272.0 2009 Value 668.3 2000 - 2008 (Maximum Value) 1023.4 Preoperational Value 200.0 ANO personnel have noted no definable increasing trends associated with the tritium levels at the discharge location. Levels detected during 2009 and previous operational years have been well below regulatory reporting limits. Therefore, the operation of ANO had no definable impact on this waterborne pathway during 2009 and levels of radionuclides remain similar to those obtained in previous operational years.
Drinking water samples were collected from two locations (indicator and control). Although ANO personnel utilize Station 14 (City of Russellville) as an indicator location due to the potential for the drinking water pathway to exist, the City of Russellville has not withdrawn water from Lake Dardanelle in the past several years.
Drinking water samples were analyzed for gross beta radionuclides, Iodine-131, gamma radionuclides and tritium. Gamma radionuclides, Iodine-131 and tritium concentrations were below the LLD limits at the indicator and control locations, which is consistent with preoperational and operational years. Gross beta concentrations at the indicator and control locations are similar as shown in Table 3.1. Listed below is a comparison of 2009 indicator results to preoperational and operational years. The results below are reported as annual average pCi/l.
Radionuclide 2009 2000 - 2008 Preoperational Gross Beta 2.18 3.09 2.0 Iodine-131 <LLD <LLD <LLD Gamma <LLD <LLD <LLD Tritium <LLD <LLD 200.0 ANO personnel have noted no definable trends associated with drinking water results at the indicator location. Therefore, the operation of ANO had no definable impact on this waterborne pathway during 2009 and levels of radionuclides remain similar to those obtained in previous operational years.
Attachment to 0CAN051001 Page 20 of 49 Groundwater samples were collected from four locations (1 control and 3 indicator locations).
Sample data was compiled, organized and is reviewed annually as a minimum to:

Groundwater samples were analyzed for tritium and gamma radionuclides. Tritium and gamma concentrations were below the LLD limits at the indicator and control locations. Listed below is a comparison of 2009 indicator results to past operational years. The results below are reported as annual average pCi/l. Groundwater data is captured in Tables 8.1 and 8.2.
Therefore, ANO operations had no significant impact on the environment or public by this waterborne pathway.
Table 8.3 has been included in the 2009 AREOR to identify tritium results from groundwater samples collected in 2006 - 2007. Groundwater tritium sampling was initiated on December 7, 2006. ANO initiated sending groundwater gamma analysis samples to River Bend Nuclear Station in 2008.
Radionuclide 2009 2006 - 2008 Tritium <LLD <LLD Gammas <LLD <LLD 2.4 Sediment Sample Results Sediment samples were collected from two locations in 2009 and analyzed for gamma radionuclides. Although Cesium-137 has been detected in previous years, all gamma radionuclides were below detectable limits in 2009. Listed below is a comparison of 2009 indicator results to past operational years. Therefore, ANO operations had no significant impact on the environment or public by this waterborne pathway. The results below are reported in picocuries per kilogram (pCi/kg)
Monitoring Period Concentration 2000 - 2008 (Minimum Value) 41.79 2009 Value < LLD 2000 - 2008 (Maximum Value) 1170.0 Since reporting levels for radionuclides in sediment have not been established, an evaluation of potential dose to the public from this media was performed as shown in Attachment 2.
Attachment to 0CAN051001 Page 21 of 49 2.5 Milk Sample Results Milk samples were not collected during 2009 due to the unavailability of indicator locations within five-miles of ANO.
2.6 Fish Sample Results Fish samples were collected from two locations and analyzed for gamma radionuclides. In 2009, gamma radionuclides were below detectable limits which are consistent with the preoperational monitoring period and operational results since 1997. Therefore, based on these measurements, ANO operations had no significant radiological impact upon the environment or public by this ingestion pathway.
2.7 Food Product Sample Results The REMP has detected radionuclides prior to 1990 that are attributable to other sources.
These include the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986 and atmospheric weapons testing.
In 2009, food product samples were collected when available from two locations and analyzed for Iodine-131 and gamma radionuclides. The 2009 levels remained undetectable, as has been the case in previous years. Therefore, based on these measurements, ANO operations had no significant radiological impact upon the environment or public by this ingestion pathway.
2.8 Interlaboratory Comparison Results RBS Environmental Laboratory analyzed interlaboratory comparison samples for ANO to fulfill the requirements of ODCM Section 2.6.3. Attachment 2, contains these results. ANOs review of RBS interlaboratory comparison indicated that 100% of the sample results (52 of 52) were within the acceptable control limits.
2.9 Land Use Census Results The latest land use census (performed in 2009) did not identify any new locations that yielded a calculated dose or dose commitment greater than those currently calculated (see Table 2.1).
Also, the land use census identified no milk-producing animals within a five-mile radius of the plant site. ANO personnel chose not to perform a garden census in 2009, which is allowed by ODCM Section 2.6.2, in lieu of broadleaf vegetation sampling in the meteorological sector (Sector 13) with the highest D/Q.

Attachment to 0CAN051001 Page 49 of 49 Sediment Dose Calculations Sediment Sample Results Sediment samples were collected from two locations in 2009 and analyzed for gamma radionuclides. Although Cesium-137 has been detected in previous years, all gamma radionuclides were below detectable limits in 2009. Therefore, ANO operations had no significant impact on the environment or public by this waterborne pathway.
In previous reports, ANO has included annual maximum dose calculations to the skin and total body. However since gamma radionuclides were below detectable limits, no calculation is being provided since there is no associated dose.
