Enclosure to 0CAN051302 Page 2 of 131 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, 2012, through December 31, 2012. This report fulfills the requirements of ANO Unit 1 Technical Specification (TS) 5.6.2 and Unit 2 TS 6.6.2.

During 2012, 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 2012, 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 2012 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 2012. Therefore, no analysis or planned course of action to alleviate problems was necessary.

Enclosure to 0CAN051302 Page 3 of 131 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 2.5-2, when averaged over any calendar quarter. Therefore, 2012 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. In 2011, ANO detected I-131 radioactivity attributed to the Fukushima Daiichi Nuclear Power Plant accident (March 11, 2011).

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 of ANO in 2012 due to unavailability. The ODCM requires collection of milk samples, if available commercially within 5 miles of the plant. ANO personnel collected vegetation samples to monitor the ingestion pathway, as specified in the ODCM, because of milk unavailability.

Lower Levels of Detection (LLDs) during this reporting period were within the acceptable limits required by Table 2.5-1 of the ODCM.

Enclosure to 0CAN051302 Page 4 of 131

Air Samples Listed below are air sampler deviations that occurred during 2012 due to electrical power outages and equipment failure. These deviations did not result in the excedence of the LLD values specified in the ODCM. As described in ODCM, B 2.5.1, Actions A.1 and A.2, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

Enclosure to 0CAN051302 Page 5 of 131 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 2012 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 ODCM Section B 2.5.2. The latest land use census was conducted in 2011. 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 did not perform a garden census since ODCM Section B 2.5.2, Actions A.1, A.2.1, and A.2.2 allows the routine sampling of broadleaf vegetation in the highest D/Q sector near the site boundary in lieu of the garden census.

Enclosure to 0CAN051302 Page 6 of 131 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 GPS 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.

Enclosure to 0CAN051302 Page 16 of 131 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, the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986 and the Fukushima Daiichi Nuclear Power Plant accident (Mach 11, 2011).

As in past years, there were no other detections of I-131. Indicator gross beta air particulate results for 2012 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 picocuries per cubic meter (pCi/m3).

Monitoring Period Result 2000 - 2011 (Minimum Value) 0.020 2012 Value 0.018 2000 - 2011 (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 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 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 8.0 millirem (mrem) shown in Table 3.1 is within the historical bounds of 2000 - 2011 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 2012 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 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.

Results are reported as annual average picocurie per liter (pCi/l).

Enclosure to 0CAN051302 Page 17 of 131 Monitoring Period Result 2000 - 2011 (Minimum Value) 272.0 2012 Value 916 2000 - 2011 (Maximum Value) 1023.4 Preoperational 200.0 ANO personnel have noted no definable increasing trends associated with the tritium levels at the discharge location. Levels detected during 2012 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 2012 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 2012 indicator results to preoperational and operational years. Results are reported as annual average pCi/l.

Radionuclide 2012 2000 - 2011 Preoperational Gross Beta 2.52 2.78 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 2012 and levels of radionuclides remain similar to those obtained in previous operational years.

Groundwater samples were collected from four REMP locations (1 control, and 3 indicator locations). During 2011, ANO incorporated sixteen additional groundwater monitoring wells into the Groundwater Protection Initiative (GPI) site program. Sample data was compiled, organized and is reviewed annually at a minimum to:

Analyze for increasing or decreasing trends at individual sample points, wells or groups of wells.

Review the radionuclides detected to determine whether changes should be made to the analysis suites or sampling frequencies for each sampling location.

Enclosure to 0CAN051302 Page 18 of 131

Evaluate the locations of radionuclides in ground water to determine if changes should be made to the sampling locations.

Review current investigation levels and determine if changes should be made.

Determine if any change to the ODCM is required.

Determine if a corrective actions/remediation is required.

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 2012 indicator results to past operational years. Results are reported as annual average pCi/l. REMP 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.

Radionuclide 2012 2006 - 2011 Iodine-131 < LLD < LLD Gamma < LLD < LLD Tritium < LLD < LLD 2.4 Sediment Sample Results Sediment samples were collected from two locations in 2012 and analyzed for gamma radionuclides. Listed below is a comparison of 2012 indicator results to past operational years.

Therefore, ANO operations had no significant impact on the environment or public by this waterborne pathway. Results are reported as pCi/kg.

Monitoring Period Result 2000 - 2011 (Minimum Value) 41.79 2012 Value < LLD 2000 - 2011 (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 3.

2.5 Milk Sample Results Milk samples were not collected during 2012 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 2012, 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.

Enclosure to 0CAN051302 Page 19 of 131 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 2012, food product samples were collected when available from two locations and analyzed for Iodine-131 and gamma radionuclides. The 2012 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 and GEL Laboratories analyzed interlaboratory comparison samples to fulfill the requirements of ODCM Section 2.5.3. Attachment 2 contains these results.

2.9 Land Use Census Results The latest land use census (performed in 2011) 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 2011, which is allowed by ODCM Section L 2.5.2, in lieu of broadleaf vegetation sampling in the meteorological sector (Sector 13) with the highest D/Q.

The I-131 in milk had a River Bend (RBS) to Reference Lab (EZA) ratio of 0.67 with the passing lower limit being 0.80 (Ratio for Agreement range of 0.80 - 1.25). The mean for RBS was 67 pCi/L while EZAs mean was 99.7 pCi/L.

Review of the data results for I-131 in milk shows consistently low values whereas the other isotopes did not and were well within the passing range. Analytics was contacted to see if there was a low bias of reporting I-131 in milk by other participants. All other participant results looked normal with no low bias responses with the sample.

A mixed gamma in water sample was also counted in the same time period as the mixed gamma in milk. The I-131 in the water sample had a RBS to EZA ratio of 1.03 indicating that RBS had a slightly higher result than the known EZA value. Data review of the weekly system background and daily background checks were performed and showed nothing out of the ordinary. There are no anomalies to explain the low reporting value of I-131 in milk. The technician that counted the sample is no longer with the lab so he cannot be questioned as to his thoughts on the low I-131 results. A new milk sample was ordered. The I-131 ratio results for the new sample were 1.05 which is well within the passing range. There are no sample preparation procedures or techniques to change in order to eliminate the low sample results in the future.

Environmental samples are analyzed and reported with a ninety-five percent confidence level.

A known standard is counted daily prior to any samples and must read within the control limits of the decay corrected activity; therefore, there is no impact accessed on previously reported data due to these results.

The criteria are based on an empirical relationship which combines prior experience and the accuracy needs of this program.

In these criteria, the judgment limits are variable in relation to the comparison of the NRC Reference Laboratorys value to its associated uncertainty. As that ratio, referred to in this program as Resolution, increases the acceptability of a licensees measurement should be more selective. Conversely, poorer agreement must be considered acceptable as the resolution decreases.

1. Introduction GEL Laboratories, LLC (GEL) is a privately owned environmental laboratory dedicated to providing personalized client services of the highest quality. GEL was established as an analytical testing laboratory in 1981. Now a full service lab, our analytical divisions use state of the art equipment and methods to provide a comprehensive array of organic, inorganic, and radiochemical analyses to meet the needs of our clients.

At GEL, quality is emphasized at every level of personnel throughout the company.

Managements ongoing commitment to good professional practice and to the quality of our testing services to our customers is demonstrated by their dedication of personnel and resources to develop, implement, assess, and improve our technical and management operations.

The purpose of GELs quality assurance program is to establish policies, procedures, and processes to meet or exceed the expectations of our clients. To achieve this, all personnel that support these services to our clients are introduced to the program and policies during their initial orientation, and annually thereafter during company-wide training sessions.

GELs primary goals are to ensure that all measurement data generated are scientifically and legally defensible, of known and acceptable quality per the data quality objectives (DQOs), and thoroughly documented to provide sound support for environmental decisions. In addition, GEL continues to ensure compliance with all contractual requirements, environmental standards, and regulations established by local, state and federal authorities.

GEL administers the QA program in accordance with the Quality Assurance Plan, GL-QS-B-001.

Our Quality Systems include all quality assurance (QA) policies and quality control (QC) procedures necessary to plan, implement, and assess the work we perform. GELs QA Program establishes a quality management system (QMS) that governs all of the activities of our organization.

This report entails the quality assurance program for the proficiency testing and environmental monitoring aspects of GEL for 2012. GELs QA Program is designed to monitor the quality of analytical processing associated with environmental, radiobioassay, effluent (10 CFR Part 50),

and waste (10 CFR Part 61) sample analysis.

This report covers the category of Radiological Environmental Monitoring Program (REMP) and includes:

Intra-laboratory QC results analyzed during 2012.

Inter-laboratory QC results analyzed during 2012 where known values were available.

Enclosure to 0CAN051302 Page 47 of 131

2. Quality Assurance Programs for Inter-laboratory, Intra-laboratory and Third Party Cross-Check In addition to internal and client audits, our laboratory participates in annual performance evaluation studies conducted by independent providers. We routinely participate in the following types of performance audits:

Proficiency testing and other inter-laboratory comparisons

Performance requirements necessary to retain Certifications

Evaluation of recoveries of certified reference and in-house secondary reference materials using statistical process control data.

Evaluation of relative percent difference between measurements through SPC data.

We also participate in a number of proficiency testing programs for federal and state agencies and as required by contracts. It is our policy that no proficiency evaluation samples be analyzed in any special manner. Our annual performance evaluation participation generally includes a combination of studies that support the following:

US Environmental Protection Agency Discharge Monitoring Report, Quality Assurance Program (DMR-QA). Annual national program sponsored by EPA for laboratories engaged in the analysis of samples associated with the NPDES monitoring program.

Participation is mandatory for all holders of NPDES permits. The permit holder must analyze for all of the parameters listed on the discharge permit. Parameters include general chemistry, metals, BOD/COD, oil and grease, ammonia, nitrates, etc.

Department of Energy Mixed Analyte Performance Evaluation Program (MAPEP). A semiannual program developed by DOE in support of DOE contractors performing waste analyses. Participation is required for all laboratories that perform environmental analytical measurements in support of environmental management activities. This program includes radioactive isotopes in water, soil, vegetation and air filters.

ERAs MRAD-Multimedia Radiochemistry Proficiency test program. This program is for labs seeking certification for radionuclides in wastewater and solid waste. The program is conducted in strict compliance with USEPA National Standards for Water Proficiency study.

ERAs InterLaB RadCheM Proficiency Testing Program for radiological analyses. This program completes the process of replacing the USEPA EMSL-LV Nuclear Radiation Assessment Division program discontinued in 1998. Laboratories seeking certification for radionuclide analysis in drinking water also use the study. This program is conducted in strict compliance with the USEPA National Standards for Water Proficiency Testing Studies. This program encompasses Uranium by EPA method 200.8 (for drinking water certification in Florida/Primary NELAP), gamma emitters, Gross Alpha/Beta, Iodine-131, naturally occurring radioactive isotopes, Strontium-89/90, and Tritium.

ERAs Water Pollution (WP) biannual program for waste methodologies includes parameters for both organic and inorganic analytes.

ERAs Water Supply (WS) biannual program for drinking water methodologies includes parameters for organic and inorganic analytes.

Enclosure to 0CAN051302 Page 48 of 131

Environmental Cross-Check Program administered by Eckert & Ziegler Analytics, Inc.

This program encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopes in soil and air filters.

GEL procures single-blind performance evaluation samples from Eckert & Ziegler Analytics to verify the analysis of sample matrices processed at GEL. Samples are received on a quarterly basis. GELs Third-Party Cross-Check Program provides environmental matrices encountered in a typical nuclear utility REMP. The Third-Party Cross-Check Program is intended to meet or exceed the inter-laboratory comparison program requirements discussed in NRC Regulatory Guide 4.15, revision 1. Once performance evaluation samples have been prepared in accordance with the instructions provided by the PT provider, samples are managed and analyzed in the same manner as environmental samples from GELs clients.

3. Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment of each area of the laboratory is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-E-001. The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GELs QA program. Internal audits are conducted at least annually in accordance with a schedule approved by the Quality Systems Director. Supplier audits are contingent upon the categorization of the supplier, and may or may not be conducted prior to the use of a supplier or subcontractor. Type I suppliers and subcontractors, regardless of how they were initially qualified, are re-evaluated at least once every three years.

In addition, prospective customers audit GEL during pre-contract audits. GEL hosts several external audits each year for both our clients and other programs. These programs include environmental monitoring, waste characterization, and radiobioassay. The following list of programs may audit GEL at least annually or up to every three years depending on the program.

The annual radiochemistry laboratory internal audit (12-RAD-001) was conducted in March 2012. Two (2) findings, three (3) observations, and three (3) recommendations resulted from this assessment. In May, 2012, each finding was closed and appropriate laboratory staff addressed each observation and recommendation.

Enclosure to 0CAN051302 Page 49 of 131 The Nuclear Procurement Issues Committee (NUPIC) follow up verification audit was conducted on October 16, 2012 through October 17, 2012. This Duke Energy/NUPIC QA audit was performed to verify that the six audit findings identified in the 2011 NUPIC audit had been successfully implemented.

The audit confirmed that the actions taken to the six findings have been adequately addressed by GEL. The Audit Report # 22837-A for Supplier Number 5644 has been posted on the NUPIC website.

4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utilized an acceptance protocol based upon two performance models. For those inter-laboratory programs that already have established performance criteria for bias (i.e., MAPEP, and ERA/ELAP), GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality control programs that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics Environmental Cross-check Program), results will be evaluated in accordance with GELs internal acceptance criteria.

5. Performance Evaluation Samples Performance Evaluation (PE) results and internal quality control sample results are evaluated in accordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as the deviation of any one result from the known value. The second criterion concerns precision, which deals with the ability of the measurement to be replicated by comparison of an individual result with the mean of all results for a given sample set.

At GEL, we also evaluate our analytical performance on a regular basis through statistical process control (SPC) acceptance criteria. Where feasible, this criterion is applied to both measures of precision and accuracy and is specific to sample matrix. We establish environmental process control limits at least annually.

For Radiochemistry analysis, quality control evaluation is based on static limits rather than those that are statistically derived. Our current process control limits are maintained in GELs AlphaLIMS. We also measure precision with matrix duplicates and/or matrix spike duplicates.

The upper and lower control limits (UCL and LCL respectively) for precision are plus or minus three times the standard deviation from the mean of a series of relative percent differences.

The static precision criteria for radiochemical analyses are 0 - 20%, for activity levels exceeding the contract required detection limit (CRDL).

6. Quality Control Program for Environmental Sample Analysis GELs internal QA Program is designed to include QC functions such as instrumentation calibration checks (to insure proper instrument response), blank samples, instrumentation backgrounds, duplicates, as well as overall staff qualification analyses and statistical process controls. Both quality control and qualification analyses samples are used to be as similar as the matrix type of those samples submitted for analysis by the various laboratory clients. These performance test samples (or performance evaluation samples) are either actual sample submitted in duplicate in order to evaluate the precision of laboratory measurements, or fortified blank samples, which have been given a known quantity of a radioisotope that is in the interest to GELs clients.

Enclosure to 0CAN051302 Page 50 of 131 Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well as surrogates and internal standards. The UCLs and LCLs for accuracy are plus or minus three times the standard deviation from the mean of a series of recoveries. The static limit for radiochemical analyses is 75 - 125%. Specific instructions for out-of-control situations are provided in the applicable analytical SOP.

GELs Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to which known quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements.

Some methods may refer to these samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125% for radiological analyses excluding drinking water matrix.

Bias (%) = (observed concentration)

100 %

(known concentration)

Precision is a data quality indicator of the agreement between measurements of the same property, obtained under similar conditions, and how well they conform to themselves.

Precision is usually expressed as standard deviation, variance or range in either absolute or relative (percentage) terms.

GELs laboratory duplicate (DUP or LCSD) is an aliquot of a sample taken from the same container and processed in the same manner under identical laboratory conditions. The aliquot is analyzed independently from the parent sample and the results are compared to measure precision and accuracy.

If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPD). The RPD must be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are less than 5 times MDC, then the RPD must be equal to or less than 100%. If one result is above the MDC and the other is below the MDC, then the RPD can be calculated using the MDC for the result of the one below the MDC. The RPD must be 100% or less. In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPD must be less than or equal to 20%. If both results are below MDC, then the limits on % RPD are not applicable.

Difference (%) = (high duplicate result - low duplicate result)

100 %

(average of results)

7. Summary of Data Results During 2012, forty-three (43) radioisotopes associated with seven (7) matrix types were analyzed under GELs Performance Evaluation program in participation with ERA, MAPEP, and Eckert & Ziegler Analytics. Matrix types were representative of client analyses performed during 2012. Of the four hundred forty-four (444) total results reported, 98% (433 of 444) were found to be acceptable. The list below contains the type of matrix evaluated by GEL.

Enclosure to 0CAN051302 Page 51 of 131 Graphs are provided in Figures 1-9 of this report to allow for the evaluation of trends or biases.

These graphs include radioisotopes Cobalt-60, Cesium-137, Tritium, Strontium-90, Gross Alpha, Gross Beta, Iodine-131, Americium-241, and Plutonium-238.

8. Summary of Participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program Eckert & Ziegler Analytics provided samples for nintety-two (92) individual environmental analyses. The accuracy of each result reported to Eckert & Ziegler Analytics, Inc. is measured by the ratio of GELs result to the known value. All results fell within GELs acceptance criteria (100%).

9. Summary of Participation in the MAPEP Monitoring Program MAPEP Series 25, 26 and 27 were analyzed by the laboratory. Of the one hundred twenty-nine (129) analyses, 94% (121 out of 129) of all results fell within the PT providers acceptance criteria. Eight analytical failures occurred: Cobalt-57 in soil, Uranium-234/235 in filter, Strontium-90 in vegetation, Uranium 234/235 in vegetation, Strontium-90 in soil, Uranium-234/235 in filter, Uranium-238 in filter and Gross Alpha in Filter.

For the corrective actions associated with MAPEP Series 26 and 27, refer to CARR120711-694, CARR120711-698, CARR121127-742, CARR121127-743, and CARR121127-744 please see Table 8.

10. Summary of Participation in the ERA MRaD PT Program The ERA MRad program provided samples (MRAD-16 and MRAD-17) for one hundred seventy-nine individual environmental analyses. All results (100%) fell within the PT providers acceptance criteria.

11. Summary of Participation in the ERA PT Program The ERA program provided samples (RAD-88, RAD-89, RAD-90 and RAD-91) for forty-four (44) individual environmental analyses. Of the 44 analyses, 93% (41 out of 44) of all results fell within the PT providers acceptance criteria. Three analytical failures occurred: Barium-133 in water, Zinc-65 in soil, and I-131 in water.

For the corrective actions associated with RAD-88, and RAD-90, refer to corrective actions CARR120306-667 and CARR120831-715 (Table 8).

12. Corrective Action Request and Report (CARR)

There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002.

A formal corrective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention of the problem is required. Formal corrective action investigations include root cause analysis.

Enclosure to 0CAN051302 Page 52 of 131 GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement. Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

Any employee at GEL can identify and report a nonconformance and request that corrective action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the event that correctness or validity of the laboratorys test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery.

Table 8 provides the status of CARRs for radiological performance testing during 2012. It has been determined that causes of the failures did not impact any data reported to our clients.

If both results are less than 5 times MDC, then the RPD must be equal to or less than 100%. If one result is above the MDC and the other is below the MDC, then the RPD can be calculated using the MDC for the result of the one below the MDC. The RPD must be 100% or less. In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPD must be less than or equal to 20%. If both results are below MDC, then the limits on % RPD are not applicable. All not applicable results are revised to 0.

SUMMARY

CORRECTIVE ACTION DISPOSITION ID# & PE FAILURE The low bias associated with the tritium result for RAD-88 initiated an investigation of the liquid scintillation detector used for the original reported result after the original vials were recounted on a different detector and met acceptance criteria.

The tritium efficiency for the detector was reviewed and a slight low bias was observed. A service call was initiated.

CARR120306-667 Tritium and carbon-14 efficiencies were calculated on all liquid ISO Documentation of PT scintillation detectors to ensure that service was not required.

Failures in RAD-88 Study - No other deficiencies were noted. The data reported using this Tritium in Water detector was also reviewed and were deemed acceptable as originally reported.

In the future, the efficiency of each detector will be monitored monthly in order to rapidly identify any change that may require service.

A second PT was successfully analyzed for this matrix.

Barium-133 All data were reviewed and it appears that the cause of the high bias was due to the calibration standard.

The reported result was counted on a detector that omitted the Hg-203 nuclide from the efficiency calibration due to its short half-life and an inability to accumulate 10,000 counts in a reasonable amount of time. The duplicate sample in the batch CARR120831-715 counted on a detector that had the Hg-203 point included in its ISO Documentation of PT efficiency calibration and generated a result of 64.83 pCi/L. This Failures in RAD-90 Study - result compares well with the assigned value of 65 pCi/L.

Barium-133 and Radium- Radium-226 226 After a review of the data, an apparent reason for this discrepancy could not be determined. Multiple steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

Two sample duplicates were also prepared and counted along with the reported result. Both results fell well within the acceptance range.

Enclosure to 0CAN051302 Page 111 of 131 CORRECTIVE ACTION DISPOSITION ID# & PE FAILURE Actions to Prevent Potential Occurrence or Recurrence:

Barium-133 In the future additional points will be included in the efficiency curve to better estimate the efficiencies across the entire energy CARR120831-715 spectrum.

(continued) Radium-226 The laboratory must assume an unidentified random error caused the high bias because all quality control criteria were met for the batch. The lab will continue to monitor the recoveries of this radionuclide to ensure that there are no issues.

MAPEP-12-RdF26 Uranium-234/233 After a thorough review of the data, the root cause of the low bias on the reported values was due to a high counting uncertainty. The counting uncertainty achieved for the U-233/4 results was approximately 100% of the reported results. Since the Relative Error Ratio between the result and the true value was 1.72, this indicates that the measured result is within the CARR120711-694 and 698 uncertainty of the measurement.

For Failures of MAPEP 26 Update January 2013 Study for Uranium 234/233 in Filters and Vegetation Originally, it was suspected that the failure of the low bias on the reported values was due to a high counting uncertainty. The counting uncertainty achieved for the U-233/4 results was approximately 100% of the reported results. However, after the receipt of a similar failure in MAPEP 27 and a conversation with Mr. David Sill of the RESL Laboratory, it is certain that the aliquot used to analyze the sample was insufficient to detect the Uranium-234/233 spiked onto the filter (which is directly related to the high counting uncertainty).

Enclosure to 0CAN051302 Page 112 of 131 CORRECTIVE ACTION DISPOSITION ID# & PE FAILURE MAPEP-12-RdV26 Uranium-234/233 After a thorough review of the data, the root cause of the low bias on the reported values was due to a high counting uncertainty. The counting uncertainty achieved for the U-233/4 results was approximately 60% of the reported results. Since the Relative Error Ratio between the result and the true value was 1.14, this indicates that the measured result is within the CARR120711-694 and 698 uncertainty of the measurement.

(continued)

Permanent Corrective/Preventive Actions or Improvements:

Since guidance on acceptable uncertainties or Action Levels are not provided, to avoid potential warnings and failures due to high counting uncertainty in the future, our internal review process has been adjusted.

If the result has measurable activity but a low count rate, the count time will be extended and the sample re-analyzed with a larger aliquot to achieve better counting statistics.

Root Cause Analysis of MAPEP-12-MaS27 Selenium After a review of the data, a definitive reason for this discrepancy could not be determined. However, it is suspected that something occurred during the digestion of the batch to CARR121127-742 produce the lower recovery. The following steps were taken to ensure that this was an isolated occurrence and that our overall MAPEP 27 Unacceptable process is within control.

and Warning - Selinium, Gross Alpha Actions Taken: MAPEP-12-MaS27 Selenium The laboratory must assume an unidentified random error caused the lower result. However, closer attention must be paid to the matrix QC failures. In the future, the samples should be re-extracted to confirm results prior to reporting.

Enclosure to 0CAN051302 Page 113 of 131 CORRECTIVE ACTION DISPOSITION ID# & PE FAILURE MAPEP-12-GrF27 Gross Alpha Prior to counting, this filter was taken through the opening and labeling procedures specified in CARR120118-659. It is not suspected that previous Gross Alpha MAPEP issues contributed to this failure. While reviewing results from previous studies, a low bias was observed. It was suspected that this bias was due to a difference in instrument efficiency due to the filter media.

To investigate further, a previous MAPEP filter containing activity was counted and used to establish an efficiency. When applied to the counts of MAPEP 27, the result were acceptable but the low bias was still observed. Source standards were then created using blank filter media from previous MAPEP studies.

CARR121127-742 The blank filters were spiked with Th-230 and counted to (continued) determine an average efficiency. When this efficiency was applied to the MAPEP 27 count, the result fell well within the acceptance range. Using the blank filter to create an instrument efficiency is part of the study instructions as an option. This efficiency is much more accurate than what was used and will be used for future MAPEP studies.

Actions taken : MAPEP-12-GrF27 Gross Alpha Since using the blank filter to create an instrument efficiency is part of the study instructions, it will be used for future MAPEP studies. GEL found that this efficiency is much more accurate than the one previously used.

Enclosure to 0CAN051302 Page 114 of 131 CORRECTIVE ACTION DISPOSITION ID# & PE FAILURE MAPEP-12-RdF27 Uranium-234/233 Upon notification of the failures, the data were reviewed again for accuracy. Investigations on quality control checks and trending were preformed to ensure that the low bias was isolated to the MAPEP sample procedure and not indicative of a systematic failure.

Also, an additional MAPEP-12-RdF27 filter was obtained and prepared per standard protocol. Based on the recommendations from Mr. David Sill of the RESL laboratory, the entire filter was used for analysis. The U-233/234 and U-238 results for this analysis were 98% of the known values. The cause of the failure was the limited sample amount used to prepare the initial sample. Multiple aliquots had been removed from the digested filter for other analyses, the RESL Laboratory CARR 121127-743 had had prepared this sample as a single analysis.

MAPEP 27 Study Action Taken: MAPEP-12-RdF26 and MAPEP-12-RdF27 Unacceptable and Warning Uranium-234/233 ratings for U234/233 in Filter Since guidance on acceptable uncertainties or Action Levels are not provided, to avoid potential warnings and failures due to high counting uncertainty in the future, our internal review process has been adjusted.

If the result has measurable activity but a low count rate, the count time will be extended and/or the sample re-analyzed using a larger sample aliquot to achieve better counting statistics.

Although the MAPEP instructions are written such that the laboratory should have confidence in using smaller aliquots and still attain sufficiently low counting uncertainties, it is now our understanding that the design of the MAPEP filter program requires the analysis of a complete filter aliquot for each parameter analyzed.

GEL will procure from MAPEP a filter for each parameter, analyze the entire filter for each parameter, and no longer perform batch duplicates for filter analysis of MAPEP samples.

Enclosure to 0CAN051302 Page 115 of 131 CORRECTIVE ACTION DISPOSITION ID# & PE FAILURE MAPEP-12-MaS26 & MAPEP-12-MaS27 Co-57 GEL received warnings for Co-57 results in the soil matrix in the past two testing rounds of the MAPEP. While Co-57 received warning flags all other gamma emitting isotopes in the soil matrix had acceptable results. Due to a potential trend, a corrective action was opened.

After receiving the results from MAPEP-27 and a second biased high result for Co-57, a thorough review of our process was conducted. This review indicated an issue associated with the calibration correction factors (absorption factors or density CARR121109-744 corrections) applied to results due to differing densities between the sample and the calibration standard. A potential 20%

MAPEP 27 Study for positive bias for Co-57 (122 keV) was observed. Note: This biased high trends of bias was within the acceptable uncertainty of the method (+/-

Cobalt-57 25%) for duplicate results. Results for Am-241(59.5 keV) were also reviewed to ensure that biases were not observed.

Action Taken: MAPEP-12-MaS26 & MAPEP-12-MaS27 Co-57 The reported results compared very well to the reference values for both MAPEP-26 and MAPEP-27 (~97% and 101%,

respectively). Since absorption factors (or density corrections) are only applied to our 100 ml aluminum can geometry for soils, no other matrices were impacted. A review of the annual analytical data for this isotope indicated that the reported data to clients were not impacted by this bias.

SUMMARY

Routine quality control (QC) testing was performed for dosimeters issued by the Environmental Dosimetry Company (EDC).

During this annual period, 100% (72/72) of the individual dosimeters, evaluated against the EDC internal performance acceptance criteria (high-energy photons only), met the criterion for accuracy and 100% (72/72) met the criterion for precision (Table 1). In addition, 100% (12/12) of the dosimeter sets evaluated against the internal tolerance limits met EDC acceptance criteria (Table 2) and 100% (6/6) of independent testing passed the performance criteria (Table 3). Trending graphs, which evaluate performance statistic for high-energy photon irradiations and co-located stations are given in Appendix A.

Two assessments were performed in 2012, one internal and one external. All findings were closed out in September of 2012.

Enclosure to 0CAN051302 Page 119 of 131 I. INTRODUCTION The TLD systems at the Environmental Dosimetry Company (EDC) are calibrated and operated to ensure consistent and accurate evaluation of TLDs. The quality of the dosimetric results reported to EDC clients is ensured by in-house performance testing and independent performance testing by EDC clients, and both internal and client directed program assessments.

The purpose of the dosimetry quality assurance program is to provide performance documentation of the routine processing of EDC dosimeters. Performance testing provides a statistical measure of the bias and precision of dosimetry processing against a reliable standard, which in turn points out any trends or performance changes. Two programs are used:

A. QC Program Dosimetry quality control tests are performed on EDC Panasonic 814 Environmental dosimeters. These tests include: (1) the in-house testing program coordinated by the EDC QA Officer and (2) independent test perform by EDC clients. In-house test are performed using six pairs of 814 dosimeters, a pair is reported as an individual result and six pairs are reported as the mean result.

Results of these tests are described in this report.

Excluded from this report are instrumentation checks. Although instrumentation checks represent an important aspect of the quality assurance program, they are not included as process checks in this report. Instrumentation checks represent between 5-10% of the TLDs processed.

B. QA Program An internal assessment of dosimetry activities is conducted annually by the Quality Assurance Officer (Reference 4). The purpose of the assessment is to review procedures, results, materials or components to identify opportunities to improve or enhance processes and/or services.

II. PERFORMANCE EVALUATION CRITERIA A. Acceptance Criteria for Internal Evaluations

1. Bias For each dosimeter tested, the measure of bias is the percent deviation of the reported result relative to the delivered exposure. The percent deviation relative to the delivered exposure is calculated as follows:

(HI - HI) 100 HI

Enclosure to 0CAN051302 Page 120 of 131 where:

HI = the corresponding reported exposure for the ith dosimeter (i.e., the reported exposure)

HI = the exposure delivered to the ith irradiated dosimeter (i.e., the delivered exposure)

2. Mean Bias For each group of test dosimeters, the mean bias is the average percent deviation of the reported result relative to the delivered exposure. The mean percent deviation relative to the delivered exposure is calculated as follows:

(HI - HI)

( ) 100 ( )

1 HI n where:

HI = the corresponding reported exposure for the ith dosimeter (i.e., the reported exposure)

HI = the exposure delivered to the ith irradiated dosimeter (i.e., the delivered exposure) n = the number of dosimeters in the test group

3. Precision For a group of test dosimeters irradiated to a given exposure, the measure of precision is the percent deviation of individual results relative to the mean reported exposure. At least two values are required for the determination of precision. The measure of precision for the ith dosimeter is:

(

Hi H

) 100 H

where:

HI = the corresponding reported exposure for the ith dosimeter (i.e., the reported exposure) 1 H = the mean reported exposure; i.e., H = Hi n

n = the number of dosimeters in the test group

Enclosure to 0CAN051302 Page 121 of 131

4. EDC Internal Tolerance Limits All evaluation criteria are taken from the EDC Quality System Manual, (Reference 2). These criteria are only applied to individual test dosimeters irradiated with high-energy photons (Cs-137) and are as follows for Panasonic Environmental dosimeters: +/- 15% for bias and +/- 12.8% for precision.

B. QC Investigation Criteria and Result Reporting EDC Quality System Manual (Reference 2) specifies when an investigation is required due to a QC analysis that has failed the EDC bias criteria. The criteria are as follows:

1. No investigation is necessary when an individual QC result falls outside the QC performance criteria for accuracy.

2. Investigations are initiated when the mean of a QC processing batch is outside the performance criterion for bias.

C. Reporting of Environmental Dosimetry Results to EDC Customers

1. All results are to be reported in a timely fashion.

2. If the QA Officer determines that an investigation is required for a process, the results shall be issued as normal. If the QC results, prompting the investigation, have a mean bias from the known of greater than +/- 20%, the results shall be issued with a note indicating that they may be updated in the future, pending resolution of a QA issue.

SUMMARY

FOR ISSUANCE PERIOD JANUARY-DECEMBER 2012 A. General Discussion Results of performance tests conducted are summarized and discussed in the following sections. Summaries of the performance tests for the reporting period are given in Tables 1 through 3 and Appendix A - Figures 1 through 4.

Table 1 provides a summary of individual dosimeter results evaluated against the EDC internal acceptance criteria for high-energy photons only. During this period, 100% (72/72) of the individual dosimeters, evaluated against these criteria met the tolerance limits for accuracy and 100% (72/72) met the criterion for precision. A graphical interpretation is provided in Appendix A - Figures 1 and 2.

Table 2 provides the Bias + Standard deviation results for each group (N = 6) of dosimeters evaluated against the internal tolerance criteria. Overall, 100% (12/12) of the dosimeter sets evaluated against the internal tolerance performance criteria met these criteria. A graphical interpretation is provided in Appendix A - Figures 3.

Enclosure to 0CAN051302 Page 122 of 131 Table 3 presents the independent blind spike results for dosimeters processed during this annual period. All results passed the performance acceptance criterion.

Appendix A - Figure 4 is a graphical interpretation of Seabrook Station blind co-located station results.

B. Result Trending One of the main benefits of performing quality control tests on a routine basis is to identify trends or performance changes. The results of the Panasonic environmental dosimeter performance tests are presented in Appendix A. The results are evaluated against each of the performance criteria listed in Section II, namely: individual dosimeter accuracy, individual dosimeter precision, and mean bias.

All of the results presented in Appendix A are plotted sequentially by processing date.

IV. STATUS OF EDC CONDITION REPORTS (CR)

During this annual period, one EDC Condition Report was issued. CR 1-2012 was issued to document the findings from the DTE Energy Audit 12-006.

V. STATUS OF AUDITS/ASSESSMENTS A. Internal EDC Internal Quality Assurance Assessment was conducted during the fourth quarter 2012. There were not any findings as a result of this assessment.

B. External The DTE Energy Audit 12-006 was conducted on June 5, 2012. Two findings were issued as a result of this audit. The EDC responded to these findings and they were closed on September 6, 2012.

Enclosure to 0CAN051302 Page 130 of 131 Annual Radiological Environmental Operating Report for 2012 ATTACHMENT 3 SEDIMENT DOSE CALCULATIONS

Enclosure to 0CAN051302 Page 131 of 131 Sediment Sample Results Sediment samples were collected from two locations in 2012 and analyzed for gamma radionuclides. Although Cesium-137 has been detected in previous years, all gamma radionuclides were below detectable limits in 2012. 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.
