Attachment to OCAN050305 Page 6 of 48 Summary The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Arkansas Nuclear One's (ANO's)

Radiological Environmental Monitoring Program (REMP) for the period January 1, 2002 through December 31, 2002. This report fulfills the requirements of ANO Unit 1 Technical Specification 5.6.2 and Unit 2 Technical Specification 6.9.4. During 2002 as in previous years, ANO detected radionuclides attributable to plant operations at the discharge location (Station 8). ANO personnel routinely monitor results from this area in order to note any trends. Their review of results from this area indicates the following:

• Tritium levels in the surface water media continue to be below regulatory reporting limits.

• Cobalt-60 and Cesium-137 levels in the sediment media are not demonstrating any consistent increase in comparison to previous years. Review indicates that 2002 levels are less than that of the historical average (1990 - 2001).

Gross beta concentrations at the Station 14 (City of Russellville) indicator drinking water location continue to remain at previous operational background measurements and similar to the levels detected at the Station 57 (City of Danville) control drinking water location.

Radioloeical 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 approximately 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 2002, 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. Review of 2002 data, in many cases, revealed undetectable radiation levels in the environment and near background level in significant pathways associated with ANO.

Attachment to OCAN050305 Page 7 of 48 Harmful Effects or Irreversible Damage The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in 2002. Therefore, no analysis or planned course of action to alleviate problems was necessary.

.Reyortin2 Levels ANO's review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples, as outlined in Units 1 and 2 Offsite Dose Calculation Manual (ODCM) Table 2.6-3, when averaged over any calendar quarter, due to ANO effluents. Therefore, 2002 results did not trigger any Radiological Monitoring Program Special Reports.

Radioactivity Not Attributable to ANO The ANO REMP detected radioactivity attributable to other sources twice. 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 in certain pathways.

Comparison to Federal and State Programs ANO personnel compared REMP data to federal and state monitoring programs as results became available. Historically, the programs used for comparison have included the U.S.

Nuclear Regulatory Commission (NRC) 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 collocated air samples and splitting or sharing sample media such as water, sediment and fish. Both programs have obtained similar results over previous years.

Attachment to OCAN050305 Page 8 of 48 Sample Deviations

+ Milk The REMP did not include milk sampling within five miles (8 km) of ANO in 2002 due to unavailability. ANO Units I and 2 ODCM require 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 All LLDs during this reporting period were within the acceptable limits required by Table 2.6-2 of the ANO Units 1 and 2 ODCM.

+ Air Samples Listed below are air sampler deviations that occurred during 2002 due to electrical failures (power loss and pump failure). These deviations did not result in a missed sample and no LLD values were exceeded. As described in footnote (a) to ANO Units 1 and 2 ODCM Table 2.6-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

• Missed Samples Air particulate and radioiodine samples were missed at the following locations due to pump failures that occurred during the sampling period:

> Air Sample Station 2 (Indicator) during the sampling periods of June 4, 2002 through June 18, 2002 and July 30, 2002 through August 13, 2002.

> Air Sample Station 6 during the sampling period of May 7, 2002 through May 21, 2002.

Attachment to OCAN050305 Page 9 of 48 One first quarter TLD (Station 150) was missed during 2002 due to vandalism. This loss was an isolated instance that did not recur during the year and was replaced with a new TLD by ANO personnel once discovered. The recovery rate for TLDs during 2002 was 99% (95 of 96).

Although these were isolated instances that were corrected by ANO personnel once discovered, footnote (a) to ANO Units 1 and 2 ODCM Table 2.6-1 allows deviations from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

• Unavailable Results ANO received analytical results in adequate time for inclusion in this report. In addition, ANO's review identified no missing results.

Program Modifications ANO made no modifications to the REMP during 2002.

Attachments contains results of air, TLD, water, sediment, fish, and food products samples collected in 2002. TLDs were analyzed by Waterford-3 Dosimetry. All remaining samples were analyzed by River Bend Station's (RBS) Environmental Laboratory. Attachment 1 also contains RBS' participation in the interlaboratory comparison program during 2002. contains dose calculations performed for sediment using a generalized equation from 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."

Attachment to OCAN050305 Page 10 of 48 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 important 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, waterbome and ingestion pathways are monitored as required by the ANO ODCM. A description of the ANO REMP utilized to monitor the exposure pathways is described in Table 1. and shown in Figures - and 1-2.

Section 2.0 of this report provides a discussion of 2002 sampling results with Section 3.0 providing a summary of results for the monitored exposure pathways.

1.3 Land Use Census ANO personnel conduct a land use census biannually, as required by ANO Units and Unit 2 ODCM Section 2.6.2. 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 broadleaf vegetation

• Attachment to OCAN050305 Page 11 of 48 The method used by ANO personnel for conducting this land use census is as follows:

• ANO personnel conduct door-to-door field surveys and/or aerial surveys in each meteorological sector out to five miles in order to locate the nearest resident and milk animal.

• Consultation with local agricultural authorities is used in instances when personal contact cannot be made.

. 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, measures distances to ANO and records 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.

• 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 OCAN050305 Page 20 of 48 2.0 Interpretation and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results Iodine-13 1 was not detected in the radioiodine cartridges during 2002, as has been the case in previous years. Indicator gross beta air particulate results for 2002 were similar to those background levels obtained in previous years of the operational REMP and well below preoperational levels as seen below. Results are reported as annual average pCi/m3 .

Monitoring Period Result Preoperational 0.05 1997 - 2001 0.02 2002 0.02 Table 3.1, which includes gross beta concentrations, provides a comparison of the indicator and control means, and further emphasizes that the airborne pathway continues to remain at background levels.

2.2 Thermoluminescent Dosimetry Sample Results ANO reports measured dose as net exposure (field reading less [transit + shield reading]) normalized to 92 days and relies on comparison of the indicator locations to the control as a measure of plant impact. Gamma radiation dose in the reporting period was compared to historical control location readings for previous years as shown in Figure 2-1.

ANO's comparison of the results to the control indicates that the ambient radiation levels are unaffected by plant operations. Although one of the quarterly readings for TLD Station 1 shown in Figure 2-1 was slightly above the historical maximum control location value of 10.0 mrem/quarter, it was within the upper (+) three standard deviation range of 11.6 mrem for the control. Therefore, levels continue to remain at or near background.

2.3 Water Sample Results Analytical results for 2002 surface water and drinking water samples were similar to those reported in previous years.

Surface water samples were collected and analyzed for gamma radionuclides and tritium. Gamma radionuclides were below detectable limits which is typically consistent with that of previous operational years. Tritium continues to be detected at the indicator location. However, the levels detected were within the range that has

Attachment to OCAN050305 Page 21 of 48 typically been seen at this location as shown below. Results are reported as annual average pCi/l.

Monitoring Period Concentration 1997 - 2001 Minimum Value 777.8 2002 Value 829.8 1997 - 2001 Maximum Value 2070.0 Preoperational Value 200.0 ANO personnel have noted no definable trends associated with the tritium levels at the discharge location. Levels detected during 2002 and previous operational years have been well below regulatory reporting limits and are typical of historical averages.

Therefore, the operation of ANO had no impact on this pathway during 2002 and levels of radionuclides remain similar to those obtained in 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 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 detectable limits at the indicator and control locations, which is consistent with preoperational and operational years. In addition, gross beta concentrations at the indicator and control locations are similar as shown in Table 3.1.

Listed below is a comparison of 2002 indicator results to preoperational and operational years. Results are reported as annual average pCiA.

Radionuclide 2002 1997 - 2001 Preoperational Gross Beta 1.05 3.18 2.0 Iodine-131 <LLD <LLD <LLD Gammas <LLD <LLD <LLD Tritium <LLD 335.0 200.0 Based on this comparison, the operation of ANO had no impact on this pathway during 2002 and radionuclides monitored for this pathway continue to remain at background levels.

Attachment to OCAN050305 Page 22 of 48 2.4 Sediment Sample Results Sediment samples were collected from two locations in 2002 and analyzed for gamma radionuclides. As in previous years, radionuclides (Cobalt-60 & Cesium-137) attributable to ANO were detected in the discharge sediment. However, ANO personnel have noted no definable trends associated with these levels at the discharge location. Levels detected during 2002 are typical of historical averages seen at this location. 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. The annual maximum dose from all radionuclides to the skin and total body was <0.01 millirem.

Design objectives given in OCFR50, Appendix I for liquid effluents are annual doses of <3 millirem total body and <10 millirem any organ. The values of <0.01 millirem for the skin and total body are well within the design objective criteria. Therefore, the level of radionuclides detected in 2002 had no significant impact on the environment or public.

2.5 Milk Sample Results Milk samples were not collected during 2002 due to the unavailability of indicator locations within 8-km of ANO. Since there are no dairies within five miles of the ANO site, it is concluded ANO's operation had no impact on this pathway in 2002.

2.6 Fish Sample Results Fish samples were collected from two locations and analyzed for gamma radionuclides. In 2002, gamma radionuclides were below detectable limits, which is 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 pathway.

2.7 Food Product Sample Results Food product samples were collected when available from two locations in 2002 and analyzed for Iodine-131 and gamma radionuclides. The 2002 levels remained undetectable, as has been the case in previous years. Therefore, since levels continue to remain at background, it can be concluded that plant operations is not impacting this pathway.

Attachment to OCAN050305 Page 23 of 48 2.8 Land Use Census Results ANO personnel conduct a land use census biannually. The most recent land use census was conducted in 2001. Therefore, a census was not required for this reporting year.

2.9 Interlaboratory Comparison Results RBS' Environmental Laboratory analyzed interlaboratory comparison samples for ANO to fulfill the requirements of ANO Units 1 and 2 ODCM Section 2.6.3.

Attachment 1, 2002 Radiological Environmental Monitoring Report, contains these results. ANO's review of RBS' interlaboratory comparison indicated that 98% of the sample results for accuracy and precision were within the acceptable control limits of the three normalized deviations. For those sample results outside the acceptable control limits, ANO's and RBS's review indicated no impact on previously reported data. Attachment 1 also provides additional discussion regarding sample results outside the acceptable control limits.

(a) The "known" values are listed with a range reflecting control (3 sigma) limits.

(b) The normalized deviation from the "known" value is computed from the deviation and the standard error of the mean; :2.000 is the warning limit and +3.000 is the control limit. This is a measure of accuracy of the analytical methods.

(c) The normalized range is computed from the mean range, the control limit, and the standard error of the range; +2.000 is the warning limit and +3.000 is the control limit.

This is a measure of precision of the analytical methods.

(d) The results reported were out of the control limits.

Attachment to OCAN050305 Page 46 of 48 Interlaboratorv Comparison Program Exceptions There was one result outside the control limits for accuracy in the 2002 cross check program participation studies. This result was in a gamma isotopic analysis of an air particulate filter sample.

The study result outside the control limits for accuracy was in the analysis of the nuclide Fe-59 in sample study 3382-125 of 09/12/2002. RBS normalized-deviation for the analysis was +3.57 with control limits of +3.00. This high bias result is considered conservative and is considered as having no impact on past results of the program. The bias high result for Fe-59 is contributed to coincidence summing effects. A coincidence summing correction was employed in the past, but was discontinued due to the production of non-conservative low-bias results. Fe-59 results were all within control limits in other cross check samples for the year 2002.

There is no impact accessed on previously reported data due to these results.

Environmental samples are analyzed and reported with a ninety-five percent confidence level that the analytical result with its associated error encompasses the "true" value.

Ninety-six percent of RBS environmental crosscheck results were within control limits for accuracy and precision during 2002.
