Summary The Annual Radiological Environmental Operating Report (AREOR) 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, through
 
December 31, 2008. This report fulfills the requirements of ANO Unit 1 Technical
 
Specification 5.6.2 and Unit 2 Technical Specification 6.6.2. 
 
During 2008 as in previous years, Entergy 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 Cesium-137 levels in the sediment media ar e not demonstrating any consistent increase in comparison to previous years. Review indicates that results for 2008 were within the
 
range of previous operational levels as discussed in Section 2.4 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 Entergy established the REMP prior to the station becoming operational (1974) to provide data on background radiation and radioactivity normally present in the area. Entergy has
 
continued to monitor the environment by sampling air, water, sediment, fish and food
 
products, as well as measuring radiation directly. Entergy 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 pre-operational
 
results to assess any impact ANO operation might have had on the surrounding
 
environment.
Attachment to 0CAN050901 Page 7 of 53
 
In 2008, 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 2008 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 2008. Therefore, no analysis or planned course of action to alleviate problems was
 
necessary.
 
Reporting Levels Entergy's review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples due to ANO effluents, as outlined in
 
Units 1 and 2 ODCM Table 2.6-3, when averaged over any calendar quarter. Therefore, 2008 results did not trigger any Radiologi cal Monitoring Program Special Reports.
 
Radioactivity Not Attributable to ANO The ANO REMP has detected radioactivity attributable to other sources. These include the 25 th 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 Direct Radiation Monitoring
 
Network and the Arkansas Department of Health (ADH).
 
The NRC Thermoluminescent Dosimeter Network Program was discontinued in 1998. 
 
Historically these results have compared to those from the ANO REMP. ANO
 
Thermoluminescent Dosimeter 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 radi ological 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 km) of ANO in 2008 due to unavailability. ANO Units 1 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 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 2008 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 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. 
 
Station Sampling Period Comment ALL 02/19/08 - 03/04/08 Due to hazardous weather conditions the bi-weekly air sample stations were not collected
 
as scheduled. The air samples were collected
 
the following day (03/05/08).

===1.0 Introduction===
 
===1.1 Radiological===
Environmental Monitoring Program 
 
Entergy 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 ANO 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 2008 sampling results and Section 3.0
 
provides a summary of results fo r 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
 
2007. 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.
 
The method used by ANO personnel for conducti ng 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.

These include the 25 th Chinese nuclear test explosion in 1980 and the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986. 
 
During 2008, 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 2008 were
 
within the range of levels obtained in previous years of the operational REMP and well
 
below preoperational levels as seen below. Results are reported as annual average pCi/m
: 3. Monitoring Period Result 2000 - 2007 (Minimum Value) 0.020 2008 Value 0.032 2000 - 2007 (Maximum Value)  0.030 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
 
provides 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 Thermoluminescent===
Dosimetry (TLD) Sample Results Entergy 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. Entergy's 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 7.51 mrem shown in Table 3.1 is within the historical bounds of 2000
 
- 2006 annual average results, which have ranged from 6.7 to 8.8 mrem. 
 
Gamma radiation dose in the reporting period was further compared to historical control
 
location readings for previous years as shown in Figure 2-1. Entergy's comparison of the
 
results to the control indicates that the ambient radiation levels are unaffected by plant
 
operations. Although the third quarter readings for TLD Stations 1, 2, 56, 108, 109, and 151
 
shown in Figure 2-1 was above the upper (+) three standard deviation range value of 9.7
 
mrem for the historical maximum control location, Entergy considers the difference to be
 
insignificant since the dose rates remain well below the limitations of 10 CFR 20.1301(a)(1)
 
and 10CFR 20.1302(b)(2)(ii), and since there has been no identifiable trends associated
 
with these stations. In addition, Entergy utilized a different vendor for TLD processing in
 
2008. Therefore, these increases can also be attributed to differences in dosimeter
 
processing.

Overall, Entergy concluded that the ambient radiation levels are not being affected by plant
 
operations.
 
===2.3 Water===
Sample Results Analytical results for 2008 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 consistent with results seen in
 
previous operational years. Tritium continues to be detected at the indicator location (Station 8) where previously monitored radioac tive 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. Results are reported as annual average pCi/l.
 
Monitoring Period Concentration 2000 - 2007 (Minimum Value) 272.0 2008 Value 1023.3 2000 - 2007 (Maximum Value) 876.3 Preoperational Value 200.0 ANO personnel have noted no definable increasing trends associated with the tritium levels
 
at the discharge location. Levels detected during 2008 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 2008 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 2008 indicator
 
results to preoperational and operational years. Results are reported as annual average
 
pCi/l.

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 2008 and levels of radionuclides remain similar to those
 
obtained in previous operational years. 
 
Groundwater samples were collected from four locations (1 - control, and 3 - indicator locations). 
 
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 2008 indicator results to past operational years. Results are
 
reported as annual average pCi/l. Groundwater data is captured in Tables 8.1 and 8.2.

===2.4 Sediment===
Sample Results Sediment samples were collected from two locations in 2008 and analyzed for gamma radionuclides. As in previous years, Cesium-137 attributable to ANO was detected in the
 
discharge sediment indicator location (Stati on 8) where previously monitored liquid radioactive effluent from the plant is periodically discharged in accordance with the
 
regulatory criteria established in the ODCM. Although it is anticipated that radionuclides
 
would be detected at this location since sediment particles provide a natural binding
 
mechanism, ANO personnel have noted no definable consistent trends associated with this
 
radionuclide at the discharge location. Cesium-137 results for 2008 were actually below the
 
minimum range of previous operational levels as seen below. Results are reported as
 
annual average pCi/kg.
Attachment to 0CAN050901 Page 24 of 55
 
Monitoring Period Concentration 2000 - 2007 (Minimum Value) 97.78 2008 Value 41.79 2000 - 2007 (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
. The annual maximum dose from Cesium-137 to the skin and total body was calculated to be  0.01 mrem.
 
Design objectives given in 10CFR50, Appendix I for liquid effluents are annual doses of  3 mrem total body and  10 mrem any organ. The values of  0.01 mrem for the skin and total body are well within the design objective criteria. Therefore, the level of Cesium-137
 
detected in 2008 had no significant impact on the environment or public by this waterborne
 
pathway.
 
2.5 Milk Sample Results Milk samples were not collected during 2008 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 2007, 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 2008, food product samples were collected when available from two locations and
 
analyzed for Iodine-131 and gamma radionuclides. The 2008 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 Land Use Census Results The latest land use census (performed in 2007) 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 2007, which is
 
allowed by ANO Units 1 and 2 ODCM Section 2.6.2, in lieu of broadleaf vegetation sampling
 
in the meteorological sector (Sector 13) with the highest D/Q.
 
===2.9 Interlaboratory===
Comparison Results RBS's Environmental Laboratory analyzed interlaboratory comparison samples for ANO to fulfill the requirements of ANO Units 1 and 2 ODCM Section 2.6.3. Attachment 2 contains
 
these results. Entergy's review of RBS's interlaboratory comparison indicated that 100% of
 
the sample results (40 of 40) were within the acceptable control limits of the three
 
normalized deviations.

(a)  The known value as determined by Analytics.
 
(b)  The normalized deviation from the "known" value is computed from the deviation and the standard error of the mean; +/-2.00 is the warning limit and +/-3.00 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.

Sediment Dose Calculations Dose calculation for the discharge sediment was performed using generalized equation
 
found in Regulatory Guide 1.109, Appendix A as follows: 
 
R =  (40) x (C) x (U) x (D) x (W)
R = Annual dose to skin or total body in mrem/year; 40 = Area-mass conversion factor given in Appendix A of Regulatory Guide 
 
1.109 in Kg/m 2;  C = 2008 maximum radionuclide concentration in pCi/kg; U = Maximum exposure time given in Table E-5 of Regulatory Guide 1.109 
 
(67 hours for teenager);
D = External dose conversion factor for standing on contaminated ground given in Table E-6 of Regulatory Guide 1.109 in mrem/hr per pCi/m 2 , and  W = Shore-width factor (0.1) given in Table A-2 of Regulatory Guide 1.109.
