Fermi 2 - 2011 Annual Radioactive Effluent Release Report Executive Summary This report is published to provide information regarding radioactive effluent monitoring at the Fermi 2 Nuclear Power Plant. The 2011 Annual Radioactive Effluent Release Report covers the period from January 1, 2011 through December 31, 2011.

The Radioactive Effluent Release Report is produced annually, as required by the Nuclear Regulatory Commission, to present detailed results of extensive monitoring of plant releases and offsite dose resulting from these releases. The data presented indicate that the operation of Fermi 2 results in offsite radiation exposures which are well below the applicable allowable levels set by the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA).

There were no releases of liquid radioactive effluents from Fermi 2 in 2011. There has not been a routine liquid radioactive discharge from Fermi 2 since 1994. Data on releases of radioactive isotopes in gaseous effluents, as well as regulatory limits and sampling methods for these releases, are contained in the body of the report and in Appendix A.

Regulatory limits for radioactive effluents pertain to allowable offsite doses rather than to quantities of radioactivity released. The highest potential single organ dose to a person living offsite due to iodines, particulates, tritium, and carbon-14 released from the plant was calculated to be 0.26 mrem, which is less than 2% of the applicable limit found in 10 CFR Part 50, Appendix I.

During 2011, no direct radiation dose to members of the public beyond the site boundary was attributed to the operation of Fermi 2, based on analysis of readings of thermoluminescent dosimeters (TLD) placed at various locations near the Fermi site.

The offsite dose due to effluents is an extremely small fraction of the 40 CFR 190 limits.

Therefore, the combined direct radiation and effluent dose due to Fermi 2 was in compliance with 40 CFR 190 in 2011.

Data on radioactivity contained in radwaste shipments to points offsite are contained in the body of the report and in Appendix A. The Offsite Dose Calculation Manual (ODCM) was not revised in 2011. Additional sections of the report address ODCM revisions, ODCM monitors which were out of service for more than 30 days in 2011, major changes in radwaste processing, the contents of outside temporary tanks, abnormal releases, and errata to previous years' reports (see page 13).

Appendix B of this report describes the Fermi Integrated Ground Water Protection Program. This program was established as part of the site's commitment to conformance with an industry-wide ground water protection initiative. This appendix also contains the results of 2011 quarterly ground water sampling, from approximately 40 monitor wells around Fermi 2 (ground water sampling has been performed under this program since the fall of 2007). Some of these monitor wells, primarily to the east and south of Fermi 2, 4

Fermi 2 - 2011 Annual Radioactive Effluent Release Report have yielded sporadic and variable trace quantities of tritium that have been attributed to the recapture of tritium from the plant's gaseous effluent. Appendix C of this report provides data on tritium concentrations in rainwater samples collected onsite which represent this recapture phenomenon. Appendix D of this report contains the meteorological joint frequency distribution tables for 2011.

Introduction During the normal operation of a nuclear power plant, most of the fission products are retained within the fuel and fuel cladding. However, small amounts of radioactive fission products and trace amounts of the component and structure surfaces which have been activated are present in the primary coolant water, as well as tritium and carbon-14. The five types of radioactive material released are noble gases, iodine, particulates, tritium, and carbon-14.

Noble Gases Some of the fission products released in airborne effluents are radioactive isotopes of noble gases, such as xenon and krypton. These noble gases are released continuously at low levels while the reactor is operating. Noble gas releases to the environment are reduced by plant systems which delay release of these gases from the plant, which allows a portion of the noble gas activity to decay within plant systems prior to release.

Noble gases are biologically and chemically nonreactive. They do not concentrate in humans or other organisms. They contribute to human radiation dose by being an external source of radiation exposure to the body. They are readily dispersed in the atmosphere.

Iodines and Particulates Fermi 2 is required to calculate offsite dose due to releases of iodine-131 and iodine-133, which are radioisotopes of iodine with half lives of 8 days and 1 day, respectively, and particulates with half-lives greater than 8 days in gaseous and liquid effluents, and tritium. The principal radioactive particulates released are fission products (e.g.,

yttrium-91m and barium-139) and activation products (e.g., cobalt-58 and cobalt-60).

Annual releases of these radionuclides are well within industry norms. Factors such as their high chemical reactivity and solubility in water, combined with the high efficiency of gaseous and liquid processing and radwaste systems, minimize their discharge.

The main contribution of radioactive iodine to human radiation dose is to the thyroid gland, where the body concentrates iodine. This exposure results from inhalation or ingestion of these iodines. Radioactive cesiums and cobalts, when ingested or inhaled, contribute to radiation exposure of tissues such as the muscle, liver, and intestines. These iodines and particulates are also a source of external radiation exposure if deposited on the ground.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Tritium Tritium, a radioactive isotope of hydrogen, is the predominant radionuclide in radioactive gaseous effluents. It is detected at Fermi 2 in ventilation exhaust samples. Tritium is also the predominant radionuclide in liquid effluents; however Fermi 2 has not conducted routine liquid radioactive waste discharges since 1994. Plant personnel are alert for evidence of unmonitored liquid tritium releases.

Carbon-14 The year 2011 is the second year for which U.S. nuclear power plants are expected to report releases of carbon-14 (C-14). The releases reported are based on calculations involving the thermal power rating of the unit and 2011 monthly capacity factors. The Fermi 2 UFSAR estimates annual gaseous C-14 releases of 9.88 curies. The calculation performed for this report estimated a total 2011 C-14 release of 16.1 curies. Since this calculation provides a higher, more conservative estimate, its results are used in this report.

Plant Effluent Monitoring Effluents are strictly monitored to ensure that radioactivity released to the environment is as low as reasonably achievable and does not exceed regulatory limits. Effluent control includes the operation of monitoring systems, in-plant and environmental sampling and analyses programs, quality assurance programs for effluent and environmental programs, and procedures covering all aspects of effluent and environmental monitoring.

The radioactive waste treatment systems at Fermi 2 are designed to collect, process, and/or delay the release of liquid and gaseous wastes which contain radioactivity. For example, the 2.0 and 2.2 minute holdup pipes delay the release of radioactive gases so that radioactive decay can occur prior to release. The offgas system provides additional delay for such gases.

Radioactivity monitoring systems are used to verify that all releases are below regulatory limits. These instruments provide a continuous indication of the radioactivity present at the release points. Each instrument is equipped with alarms and indicators in the control room. The alarm setpoints are low enough to ensure that applicable limits will not be exceeded. In some cases, these alarms restrict the release. For example, several alarms cause building ventilation systems to be shut down and/or gaseous releases to be diverted to the standby gas treatment system.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report All wastes are evaluated to identify the specific concentrations of radionuclides being released. Sampling and analysis provide a more sensitive and precise method of determining effluent composition than monitoring instruments.

A meteorological tower is located on the Fermi 2 site. It is linked to computers which record the meteorological data. These data are used in calculating dispersion and deposition factors, which are essentially dilution factors between plant release points and points offsite. Coupled with the effluent release data, these factors are used to calculate dose to the public.

Beyond the plant, devices maintained in conjunction with the Radiological Environmental Monitoring Program constantly sample the air in the surrounding environment. Frequent samples of other environmental media, such as water and vegetation, are also collected to verify that the station radiological effluent program is being appropriately implemented without impact to the surrounding environment.

Exposure Pathways to People Radiological exposure pathways define the methods by which people may become exposed to radioactive material. The major pathways of concern are those which could cause the highest calculated radiation dose. These projected pathways are determined from the type and amount of radioactive material released, the environmental transport mechanism, and the use of the environment. The environmental transport mechanism includes consideration of physical factors, such as the hydrological and meteorological characteristics of the area.

An important factor in evaluating the exposure pathways is the use of the environment.

This is evaluated in the annual Land Use Census. Many factors are considered, such as the locations of homes, gardens, and milk or meat animals in the area.

The release of radioactive gaseous effluents involves pathways such as external whole body exposure, deposition of radioactive material on plants, deposition on soil, inhalation and ingestion by animals raised for human consumption, and inhalation by humans. The release of radioactive material in liquid effluents involves pathways such as drinking water and fish consumption.

7

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Although radionuclides can reach humans by many different pathways, some result in greater dose than others. The most significant pathway is the exposure pathway which will provide the greatest dose to a population, or to a specific individual. Identification of the most significant pathway depends on the radionuclides involved, the age and diet of the individual, and the location of the individual's residence. Doses delivered to the total body and to specific organs were calculated. The organ receiving the greatest dose is important in determining compliance with dose limits. The standard assumptions used in dose calculation result in conservative dose estimates.

Dose Assessment Dose is energy deposited by radiation in an exposed individual. Whole body exposure to radiation involves the exposure of all organs. Most exposures due to external sources of radiation are of this type. Both non-radioactive and radioactive elements can enter the body through inhalation or ingestion. When they do, they are usually not distributed evenly. For example, iodine concentrates in the thyroid gland, cesium collects in muscle and liver tissue, and strontium collects in bone tissue.

The total dose to organs from a given radionuclide depends on the amount of radioactive material present in the organ and the amount of time that the radionuclide remains in the organ. Some radionuclides remain for very short times due to their rapid radioactive decay and/or elimination rate from the body, while other radionuclides may remain in the body for longer periods of time. The form of the radionuclide (soluble vs. insoluble) and the method of uptake also influence residence times in the body.

The maximum dose to the general public in the area surrounding Fermi 2 is calculated for periods of gaseous release and for each liquid release. The dose due to radioactive material released in gaseous effluents is calculated using factors such as the amount of radioactive material released, the concentration beyond the site boundary, the locations of exposure pathways (cow milk, goat milk, vegetable gardens and residences), and usage factors (inhalation and food consumption). The dose due to radioactive material released in liquid effluents is calculated using factors such as the total volume of liquid, the total volume of dilution water, near field dilution, and usage factors (water and fish consumption). These calculations produce a conservative estimation of the dose.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Radioactive Effluent Monitoring Results This section summarizes the results of effluent monitoring and offsite dose calculation for the year 2011. Calculated offsite doses are compared with Nuclear Regulatory Commission limits, and these limits are summarized in Appendix A. Appendix A also contains a detailed discussion of the methods used to determine quantities of radioactivity released in effluents, the types of solid radwaste shipped offsite, as well as tables of individual radionuclides released in effluents and shipped as solid radwaste. There were no routine releases of liquid radioactive effluents from Fermi 2 in 2011. There has not been a routine liquid radioactive discharge from Fermi 2 since 1994.

The data in the following gaseous effluent tables represent continuous and batch releases.

In 2011, there were two recorded containment purges in which radioactivity was detected. The total time for these purges was 1499 minutes. Based on recorded start and stop times, the shorter of these purges lasted 179 minutes, the longer lasted 1320 minutes, and the average purge length was 750 minutes. The amounts of radioactivity released in these purges is very small compared with the amounts released in continuous releases.

For noble gas releases in the fourth quarter of 2011, the "less than" value in units of microcuries per cubic centimeter (tCi/cc) is used because noble gases were not detected; this value represents the lower limit of detection (LLD) of Xe-133 in a single sample. A definitive explanation for this lack of detection in the fourth quarter was not found; however noble gas detection capability is usually near LLD levels, and noble gases were again detected in the first quarter of 2012.

The offsite dose impact of the above releases was evaluated by calculating organ doses to the most highly exposed individual living near the plant due to 1-131, 1-133, H-3, C-14 and particulates with half lives greater than 8 days. This exposure is assumed to be occurring via the pathways of inhalation, vegetation ingestion, and direct radiation from material deposited on the ground. The results of this calculation are shown in the following table:

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Table 5 2011 Gaseous Effluent Dose to Organ Receptor with Highest Single Organ Dose Bone 2.63E-01 mrem Liver 7.33E-02 mrem Thyroid 1.12E-01 mrem Kidney 7.34E-02 mrem Lung 7.32E-02 mrem GI-LLI 7.33E-02 mrem Total body 7.33E-02 mrem The highest single organ dose is 2.63E-01 mrem to the bone. This is 1.8% of the federal limit of 15 mrem specified in 10 CFR 50, Appendix I.

In addition, gamma and beta air dose at the site boundary due to noble gases is calculated.

In 2011, gamma air dose was 9.51E-04 mrad, 0.01% of the 10 mrad annual limit; beta air dose in 2011 was 4.23E-04 mrad, 0.002% of the 20 mrad annual limit.

Title 40, Part 190 of the Code of Federal Regulations requires that dose to an individual in the unrestricted area from the uranium fuel cycle, including direct radiation dose, be limited to 25 mrem/year to the total body and 75 mrem/year to the thyroid. During 2011, there was no direct radiation dose attributed to the operation of Fermi 2 beyond the site boundary, based on analysis of offsite TLD readings. Based on Table 5 above, the offsite dose due to effluents is 0.29% and 0.15% of 40 CFR 190 limits for the total body and thyroid, respectively. Therefore, Fermi 2 was in compliance with 40 CFR 190 in 2011.

Potential dose to visitors at Fermi 2 due to all radioactive effluents, including noble gases, was also calculated. The Offsite Dose Calculation Manual (ODCM) considers persons visiting the Fermi 2 Visitors Center (4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months s/year), and persons ice fishing on Lake Erie near the plant (240 hour0.00278 days 0.0667 hours 3.968254e-4 weeks 9.132e-5 months s/year), to be visitors. Using ODCM assumptions about these categories of visitors, the maximum potential dose to a visitor to Fermi 2 in 2011 was 3.06E-03 mrem to the maximally exposed organ (bone) and 2.14E-03 mrem to the total body. These doses are below the annual maximum offsite doses due to gaseous effluents shown in Table 5, and are very small fractions of the 100 mrem/year limit for individual members of the public due to licensed operation of the plant provided in 10 CFR 20.1301.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report ODCM Revisions The ODCM was not revised in 2011.

ODCM Monitors Out of Service The Radwaste Building SPING monitor was administratively removed from service on December 13, 2010. This monitor was not damaged. Radwaste Building ventilation was not in service for an extended period due to duct cleaning necessitated by a flooding event which occurred on December 1, 2010. (This event was described in the Abnormal Radiological Releases section of the 2010 Annual Radioactive Effluent Release Report.)

The Radwaste Building SPING monitor was returned to service on May 13, 2011, after ventilation duct decontamination was completed.

Outside Temporary Tanks In 2011 no outside temporary tank exceeded the 10 curie content limit for nuclides other than tritium and dissolved or entrained noble gases.

Major Changes to Radioactive Waste Systems There were no major changes to radioactive waste systems in 2011.

Abnormal Radiological Releases There were no abnormal radiological releases in 2011.

Errata/Corrections to Previous ARERRs The 2010 ARERR reported an abnormal radiological release incident which occurred on December 1, 2010. The hard-to-detect nuclide Fe-55 was inadvertently omitted from the list of nuclides released, and it was not included in the offsite dose calculation. It is now calculated that 7.08E-05 curies of Fe-55 were released in this incident. However its inclusion in offsite dose calculations has a negligible effect: the reported maximum offsite dose due to this release (1.3E-06 mrem to the total body and a maximum organ dose of 4.5E-6 mrem to the GI tract) is unchanged.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Regulatory Limits for Radioactive Effluents The Nuclear Regulatory Commission (NRC) limits on liquid and gaseous effluents are incorporated into the Fermi 2 Offsite Dose Calculation Manual. These limits prescribe the maximum doses and dose rates due to radioactive effluents resulting from normal operation of Fermi 2. These limits are described in the following sections.

A. Gaseous Effluents I. Dose rate due to radioactivity released in gaseous effluents to areas at and beyond the site boundary shall be limited to the following:

a) Noble gases Less than or equal to 500 mrem/year to the total body.

Less than or equal to 3000 mrem/year to the skin.

b) Iodine-131, iodine-133, tritium, and for all radionuclides in particulate form with half lives greater than 8 days Less than or equal to 1500 mrem/year to any organ.

II. Air dose due to noble gases to areas at and beyond the site boundary shall be limited to the following:

a) Less than or equal to 5 mrad for gamma radiation Less than or equal to 10 mrad for beta radiation

- During any calendar quarter b) Less than or equal to 10 mrad for gamma radiation Less than or equal to 20 mrad for beta radiation

- During any calendar year 15

Fermi 2 - 2011 Annual Radioactive Effluent Release Report III. Dose to a member of the public from iodine-131, iodine-133, tritium, and all radionuclides in particulate form with half lives greater than 8 days in gaseous effluents released to areas at and beyond the site boundary shall be limited to the following:

a) Less than or equal to 7.5 mrem to any organ

- During any calendar quarter b) Less than or equal to 15 mrem to any organ

- During any calendar year Note: The calculated site boundary dose rates for Fermi 2 are based on identification of individual isotopes and on use of dose factors specific to each identified isotope or a highly conservative dose factor. Since individual isotopes are identified, average energy values are not used in these calculations, and therefore are not reported even though their use in these calculations is allowed by Regulatory Guide 1.21.

B. Liquid Effluents I. The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to ten times the concentrations specified in Title 10 of the Code of Federal Regulations (10 CFR) Part 20 (Standards for Protection Against Radiation), Appendix B, Table 2, Column 2 for radionuclides other than dissolved or entrained noble gases, as required by the Fermi 2 Offsite Dose Calculation Manual. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 (.0002) microcuries/ml total activity. This limit is based on the Xe-135 air submersion dose limit converted to an equivalent concentration in water as discussed in the International Commission on Radiological Protection (ICRP) Publication 2.

II. The dose or dose commitment to a member of the public from radioactive materials in liquid effluents released to unrestricted areas shall be limited to the following:

a) Less than or equal to 1.5 mrem to the total body Less than or equal to 5 mrem to any organ

- During any calendar quarter b) Less than or equal to 3 mrem to the total body Less than or equal to 10 mrem to any organ

- During any calendar year As noted previously, Fermi 2 did not perform radioactive liquid releases in 2011.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Measurements and Approximations of Total Activity in Radioactive Effluents As required by NRC Regulatory Guide 1.21, this section describes the methods used to measure the total radioactivity in effluent releases and to estimate the overall errors associated with these measurements. The effluent monitoring systems are described in Chapter 11.4 of the Fermi 2 Updated Final Safety Analysis Report (UFSAR).

A. Gaseous Effluents L Fission and Activation Gases Samples are obtained from each of the six plant radiation monitors which continuously monitor the five ventilation exhaust points. The fission and activation gases are quantified by gamma spectroscopy analysis of periodic samples.

The summary values reported are the sums of all fission and activation gases quantified at all monitored release points.

I. Radioiodines Samples are obtained from each of the six plant radiation monitors which continuously monitor the five ventilation exhaust points. The radioiodines are entrained on charcoal and then quantified by gamma spectroscopy analysis.

For each sample, the duration of sampling and continuous flow rate through the charcoal are used in determining the concentration of radioiodines. From the flow rate of the ventilation system, a rate of release can be determined.

The summary values reported are the sums of all radioiodines quantified at all continuously monitored release points.

17

Fermi 2 - 2011 Annual Radioactive Effluent Release Report II. Particulates Samples are obtained from each of the six plant effluent radiation monitors which continuously monitor the five ventilation exhaust points. The particulates are collected on a filter and then quantified by gamma spectroscopy analysis.

For each sample, the duration of sampling and the continuous flow rate through the filter are used in determining the concentration of particulates.

From the flow rate of the ventilation system, a rate of release can be determined.

Quarterly, the filters from each ventilation release point are composited and then radiochemically separated and analyzed for strontium (Sr)-89/90.

The summary values reported are the sums of all particulates quantified at all monitored release points.

IV. Tritium Samples are obtained from each of the six plant effluent radiation monitors which continuously monitor the five ventilation exhaust points. The sample is passed through a bottle containing water and the gaseous tritium is collected in this water. Portions of the collecting water are analyzed for tritium using liquid scintillation counting techniques. For each sample, the duration of sample and sample flow rate is used to determine the concentration. From the flow rate of the ventilation system, a release rate can be determined.

In addition to tritium releases from the five ventilation exhaust points, gaseous tritium releases from the Condensate Storage Tank and Condensate Return Tank have been calculated. These releases are due to evaporation of tritiated water in these tanks which is released through tank vents. However this is not a significant release point for tritium, contributing well less than 1% of total tritium releases. These releases were calculated to total 8.8E-3 curies in 2011; adding them to reported tritium releases from the ventilation release points does not change the reported release quantities, which are greater than 10 curies in each quarter and are expressed to three significant digits.

The summary values reported are the sums of all tritium quantified at all monitored release points.

V. Gross Alpha The gaseous particulate filters from the six plant effluent radiation monitors are stored for one week to allow for decay of naturally occurring alpha 18

These filters are then analyzed for gross alpha radioactivity by gas proportional counting, and any such radioactivity found is assumed to be plant related: The quantity of alpha emitters released can then be determined from sample flow rate, sample duration, and stack flow rate.

The summary values reported are the sums of all alpha emitters quantified at all monitored release points.

VI. Carbon-14 Carbon-14 releases are calculated using a method published by the Electric Power Research Institute in December 2010. Plant rated thermal power and monthly capacity factors were used in the calculation of quarterly releases.

B. Liquid Effluents The liquid radwaste processing system and the liquid effluent monitoring system are described in the Fermi 2 UFSAR. Fermi 2 did not perform any releases of radioactive liquid effluents in 2011.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report

SUMMARY

Fenni personnel conclude that the occasional positive tritium sample results in ground water from the shallow and deep monitor wells is not due to a leak from plant systems.

Tritium in ground water in the shallow aquifer is the result of washout and recapture of tritium in precipitation that has passed through gaseous effluent from monitored plant systems. Low-level tritium activity was only detected in ground water from the bedrock aquifer in one sample and this result is deemed spurious because none of the adjacent shallow aquifer wells have elevated tritium levels nor is there a credible source for licensed material in the bedrock aquifer.

PROGRAM OVERVIEW Quarterly sampling and gauging of the Fermi 2 Integrated Ground Water Protection Program (IGWPP) monitor wells continued uninterrupted in 2011. Procedurally, each IGWPP specified monitor well is required to be sampled for tritium and plant-related gamma-emitting radioisotopes each quarter. Furthermore, once per year water from three monitor wells most likely to be contaminated by leaked or spilled material is analyzed for hard-to-detect (HTD) radionuclides (Fe-55, Sr-89, and Sr-90).

Samples analyzed for gamma-emitting radionuclides, as well as HTDs, are counted to environmental lower limits of detection (LLD) for each given radioisotope of interest, with the exception of La-140 and Ba-140 (due to their extremely short half-lives). For tritium there is no required limit of detection, beyond what is prescribed for ground water samples taken as part of the site's Radiological Environmental Monitoring Program (REMP). The REMP Lower Limit of Detection (LLD) is set at 2,000 pCi/L which is 1/ 1 0 th of the EPA's drinking water limit of 20,000 pCi/L. Fermi 2's contract laboratory achieved LLDs for tritium of 500 pCi/L, or less, for all ground-water samples taken during 2011.

In 2011 Fermi personnel continued to take an additional sample split for tritium analysis.

These samples were analyzed for the presence of tritium by the Fermi chemistry laboratory. This process ensures more accurate data for shipping the samples to the offsite contract laboratory, but, more importantly, to quickly determine if abnormal levels of tritium are in site ground water as the result of a leak of tritiated process water.

26

Fermi 2 - 2011 Annual Radioactive Effluent Release Report RESULTS Deep Wells (Table 1)

Tritium was not detected in samples of ground water from the Fermi 2 deep monitor wells, with the exception of a ground-water sample from monitor well EF2-07-015D (402 pCi/L). Plant-related gamma-emitting radioisotopes were not detected in any samples collected from deep monitor wells in 2011.

Shallow Wells (Table 2)

Most shallow monitor wells have consistently yielded results indicating that tritium is not present at the detection limit. Of the 29 shallow monitor wells that are sampled quarterly (periodic sample events), only 11 samples from seven wells produced results with tritium levels above the detection limit. The positive results were sporadic and variable with tritium activities all less than 1174 pCi/L (less than 1/ 1 0 th the EPA drinking water limit for tritium). Plant-related gamma-emitting radioisotopes or hard-to-detect radioisotopes were not detected in any ground-water samples collected from shallow monitor wells in 2011.

Emergent Sample Events (Table 3)

In 2011 Fermi 2 performed several emergent sample events. The first emergent sample event (event: E-2011-G-01) was undertaken in response to unusual tritium activity in ground water from two monitor wells located north of the Fermi 2 Protected area, in the vicinity of the Circulating Water Pump House (CWPH). The unusual activity was identified in the screening samples analyzed on-site by Fermi Chemistry laboratory technicians within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months of the samples being taken. Because of the proximity of the monitor wells to the liquid radioactive waste decant line Radiological Engineering personnel decided to resample the monitor wells that produced the ground water with the unusual activity (EF2-07-015S and EF2-07-016S) as well as a third monitor well (392S) in the vicinity. These ground water samples were analyzed by Fermi 2 Chemistry technicians and split samples were sent to the contract laboratory for analysis as well.

Tritium was not detected in any of the samples taken during the course of this emergent sample event.

All subsequent emergent sample events (E-2011-G-02 through E-2011-G-07) were performed in response to the discovery of indications on a spare condensate line associated with the Fermi 2 Condensate Return Tank (CRT). Analytical results from these emergent sample events indicate that this condensate line has not begun to leak.

27

Fermi 2 - 2011 Annual Radioactive Effluent Release Report DISCUSSION Results of tritium analysis of ground water sampled in 2011 have shown that ground water from many of the site's wells have never yielded a positive result. In 2011, positive ground water results for tritium ranged from 171 - 1174 pCi/L. Furthermore, since the Integrated Ground Water Protection Program was initiated in the Fall of 2007, plant-related gamma isotopes or hard-to-detect isotopes have never been indentified in ground-water samples from any of the monitor wells.

If the tritium found in ground water from shallow wells was attributable to a leaking plant system then one would expect the levels to be consistent, or steadily increase, over time; especially during the winter when there is, normally, less recharge from surface water.

Instead the results show periodic low-level hits for tritium in ground water with no clear trend. This pattern is more consistent with what one would expect to see if the tritium was attributable to recapture in precipitation. Recapture of tritium emitted from nuclear power plant stacks in precipitation is well documented and these emissions are continuously monitored and reported annually by the utility as part of an approved effluents program. A tritium rain-water washout study performed at the Fermi site revealed that tritium is commonly found in rain water collected at the site. Tritium activity in rain water samples, taken at the site over a period of two months, ranged from ca. 400 pCi/L to 5,750 pCi/L.

In 2011 tritium was found at very low levels in ground water from one deep monitor well. The positive result (402 pCi/L) was from a third-quarter ground water sample from monitor well EF2-07-015D, located outside of the Fermi 2 Protected Area to the west of the CWPH. This positive result is considered spurious because no other samples collected from this monitor well in 2011 produced a positive result and the location of that monitor well is "upstream" from the Fermi 2 power block (local bedrock ground-water flow direction is from the northeast to southwest) which makes it highly improbable that that ground water could become contaminated with tritium from the plant.

Furthermore, deep monitor wells in the vicinity of Fermi 2 are screened 40-45 feet below ground surface in bedrock. An approximately 10-foot thick inorganic clay layer between surficial aquifer and the bedrock aquifer impedes flow to such a degree that the bedrock aquifer is saturated and under pressure to the point that ground water in deep monitor wells rises to a level several feet above the top of the clay layer. Plant components outside of buildings that contain tritiated water are either above ground in tanks or piping running through aggregate at or above the water table. If these components were to generate a leak the contamination would be evident by the presence of high levels of activity in nearby shallow monitor wells screened in the surficial aquifer. Furthermore, buildings completed in bedrock (e.g. Reactor Building, Turbine Building, and Radwaste Building), that contain contaminated systems, are so far below the potentiometric surface that, should they leak, ground water would flow into the building and therefore the leak 28

Fermi 2 - 2011 Annual Radioactive Effluent Release Report could not be a source of contamination under any probable circumstance (for an evaluation of this see Fermi UFSAR, Chapter 2).

Under these conditions (hydrogeological and plant construction) it is highly improbable that any activity attributed to tritium in ground water from deep monitor wells is indicative of plant-related tritium because there is no known pathway for plant-related tritium to contaminate the bedrock aquifer. Furthermore, to date, detectible tritium activity in the surficial aquifer, when it occurs, is far too low to be a plausible source of tritium in the bedrock aquifer. Additionally, natural radioisotopes commonly found in bedrock, such as Pb-210, produce low-energy betas in a similar energy range as tritium and may cause spurious results. The low-level of activity in ground water from deep monitor wells may also be attributable to chemiluminescence due to natural compounds that occur in the hard water from the bedrock (Bass Islands Group) dolomite.

In 2011 several emergent sample events were conducted. The first event was performed in response to tritium activity in ground water samples taken from two monitor wells near the CWPH during the first quarter periodic sample event. Analysis of the samples taken during this emergent sample event did not detect any tritium. Furthermore, tritium was not detected in ground water samples from these wells during periodic sampling for the rest of 2011. Therefore, the samples that initially showed tritium activity were deemed spurious.

The other emergent sample events were performed to ensure that an at-risk spare condensate line from the CRT has not begun to leak. If this line developed a leak, that leak could be identified by analyzing ground water from adjacent monitor wells for tritium. To ensure that such a condition did not go undetected, Radiological Engineering personnel established an emergent sample routine to ensure the sentinel wells in the vicinity of the condensate tank area are sampled monthly (credit was taken for the months when the monitor wells were sampled as part of the quarterly, periodic, sample program).

Based on the results of these samples, there is no indication of condensate leaking from this line at this time.

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Appendix C Rainwater Data and Analysis 36

Fermi 2 - 2011 Annual Radioactive Effluent Release Report Fermi 2 has documented the phenomenon of rainwater washout of gaseous effluents, in which tritium concentrations above background levels are routinely detected in rainwater samples collected on the Fermi 2 site. These positive samples are most often observed to the east of the Fermi plant, in prevailing wind direction from the plant and near the largest gaseous tritium release point--the' turbine building ventilation exhaust vent. The Nuclear Regulatory Commission has also recognized this phenomenon of recapture of legally released gaseous effluents in NRC Regulatory Issue Summary 2008-03.

In order to continue to monitor this phenomenon, Fermi 2 collects rainwater samples and stormwater outfall samples at least once per quarter. These samples are analyzed for tritium, the radionuclide most likely to be detected. The table and map at the end of this appendix show tritium results and collection locations for 2011 rainwater samples. The following general points may be made about these data:

1) Higher rainwater tritium levels were detected east of the plant. This is to be expected based on the prevailing wind direction and proximity to the turbine building vent, as explained above. It is also consistent with the occasional detection of tritium in shallow groundwater wells, as mentioned in Appendix B.

2) Detection of tritium in rainwater samples is more frequent and at somewhat higher levels than in shallow groundwater wells. This is consistent with the dilution of rainwater tritium prior to its occurrence in groundwater wells.

3) Higher tritium levels seen at the stormwater outfall can be explained by runoff of relatively highly tritiated water from plant roofs (near plant vents).

4) Higher tritium levels in rainwater near the CST can be explained by periodic venting of tritiated water vapor from the CST and CRT (minor release points for tritium).

5) All rainwater and stormwater tritium concentrations were less than one tenth of the EPA drinking water limit. That is, the EPA considers water with tritium concentrations greater than 10 times the levels detected in Fermi rainwater to be safe for drinking.

The table on the following page presents 2011 rainwater and stormwater tritium analyses.

The designation "< LLD" indicates that tritium in the sample was less than the calculated lower limit of detection for that sample.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Executive Summary This Annual Radiological Environmental Operating Report is a detailed report on the Radiological Environmental Monitoring Program (REMP) conducted at Detroit Edison's Fermi 2 nuclear power plant from January 1 through December 31, 2011.

Samples collected as part of the REMP program were analyzed by GEL Laboratories, LLC. Radioactivity measurements for these samples are reported in terms of sample concentration or less than the Lab's Minimum Detectable Activity (MDA). Standard units of measure for reporting radioactivity are the Curie (Ci) for the amount of activity, and the Roentgen (R) for the amount of radiation exposure in free air. The unit of radioactivity used in this report is the picocurie (pCi). A picocurie is one-one trillionth of a curie. The unit of direct radiation used in this report is milliroentgen (mR). A milliroentgen is one-one thousandth of a roentgen. All radioactivity measurements for samples found to contain radioactivity are reported with a 2 sigma counting error, a standard counting practice.

The Radiological Environmental Monitoring Program is divided into four major parts.

These four parts are direct radiation monitoring, atmospheric monitoring, terrestrial monitoring, and aquatic monitoring. The results of 2011 data showed that environmental radioactivity levels have not increased from background radioactivity levels detected prior to the operation of Fermi 2.

Direct radiation measurements were taken at 79 locations using thermoluminescent dosimeters (TLD). The average quarterly exposure was 14.3 mR/standard quarter for indicating locations. This average exposure is equivalent to the ambient radiation levels measured prior to the operation of Fermi 2.

Atmospheric monitoring results for 2011 showed radioactivity attributable to the nuclear accident at Fukushima, Japan. In addition, naturally occurring radioactivity was detected and was consistent with levels measured prior to the operation of Fermi 2. No radioactivity attributable to activities at Fermi 2 was detected greater than the MDA in any atmospheric samples during 2011.

Terrestrial monitoring results for 2011 of milk, groundwater, and leafy garden vegetable samples, showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing. The radioactivity levels detected were consistent with levels measured prior to the operation of Fermi 2. No radioactivity attributable to activities at Fermi 2 was detected greater than the MDA in any terrestrial samples during 2011.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Aquatic monitoring results for 2011 of drinking water, surface water, sediment, and fish, showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and were consistent with levels measured prior to the operation of Fermi 2. No radioactivity attributable to activities at Fermi 2 was detected above the MDA in any aquatic samples during 2011.

REMP sampling did not identify any radioactivity above the MDA attributable to the operation of Fermi 2.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Radiological Environmental Monitoring Program Results Direct Radiation Monitoring Radiation is a normal component of the environment resulting primarily from natural sources, such as cosmic radiation and naturally occurring radionuclides; and to a lesser extent, from manmade sources such as fallout from past nuclear weapons testing. The earth is constantly bombarded by cosmic radiation in the form of high energy gamma rays and particulates. The earth's crust also contains natural radioactive material, such as uranium and potassium-40, which contributes to the background radiation. Direct radiation monitoring primarily measures ionizing radiation from cosmic and terrestrial sources.

Thermoluminescent Dosimeters Fermi 2 uses thermoluminescent dosimeters (TLDs) to measure direct gamma radiation in the environs of Fermi 2. The TLDs are thoroughly tested to comply with NRC Regulatory Guide 4.13 and American National Standards Institute's (ANSI) publication N545-1975, which assure accurate measurements under varying environmental conditions before being placed in the field.

Fermi 2 has 79 TLD locations within a fifteen mile radius of the plant. Of the 79 TLD locations, 26 are located on-site and are not used for comparison with the control locations. These 26 TLDs are affected by Hydrogen Water Chemistry's sky shine and are not representative of off-site dose. Indicator TLDs are located within a ten mile radius of the plant and control TLDs are located at a distance that is outside the potential influence of the plant. While in the field, TLDs are exposed to background radiation and, if measurable, gaseous effluents and direct radiation from Fermi 2. Environmental TLDs are exchanged and processed on a quarterly basis. TLD data are reported in terms of milliroentgen per standard quarter (mR/std qtr), with a standard quarter being 91 days.

3

Fermi 2 - 2011 Annual Radiological Environmental Operating Report In 2011, the average exposure for TLDs at all off-site indicator locations was 14.3 mR/std qtr and for all control locations was 12.5 mR/std qtr. These exposures are consistent with preoperational and past operational measurements as shown in Figure 1.

Atmospheric Monitoring A potential exposure pathway to people is inhalation of airborne radioactive materials.

Fermi 2 continuously samples the ambient air surrounding Fermi 2 for radioactivity. Air sampling began in 1979 during the preoperational program. At each sampling location, a mechanical air sampler is used to draw a continuous volume of air through two filters designed to collect particulates and radioiodines. Air samples are collected weekly and analyzed for gross beta radiation and iodine-131 gamma radiation. The particulate filters for each sampling location are combined on a quarterly basis to form a "composite sample" and are analyzed for gamma emitting radionuclides. There are four indicator sampling locations which were selected based on an evaluation of the predominant wind directions. A fifth sampling location is approximately fourteen miles west of the plant and is considered to be in a location unaffected by the operation of the plant. This is used as the control location.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Air Sampling On October 16, 1980, the People's Republic of China conducted an atmospheric nuclear weapon test. The fallout from this test was detected in Fermi 2 preoperational environmental air samples in 1981 (see Figure 2). The average gross beta for 1981 was 1.60E-1 pCi/cubic meter for indicator samples and 2.40E-1 pCi/cubic meter for control samples which was a factor of ten times greater than background gross beta. Gamma spectroscopic analyses of the particulate filters indicated cesium-137, cerium-141, cerium-144, ruthenium-103, ruthenium-106, zirconium-95, niobium-95, manganese-54, and antimony-125 in the atmosphere as a result of this test. In 1986, as shown in Figure 2, there was a slight increase in gross beta activity and a 2.70E-1 pCi/cubic meter "spike" in the iodine-131 activity. These elevated levels in 1986 are attributed to the nuclear accident at Chernobyl on April 26, 1986. For all other years, the iodine-131 activity was below the lower limit of detection (LLD) of 7.0E-2 pCi/cubic meter.

On March 11, 2011, following the Tohoku earthquake and tsunami the Fukushima Daiichi Nuclear Power Plant in Japan, experienced a series of equipment failures, fuel-melt, and releases of radioactivity to the environment.

Within weeks of the accident, US nuclear power plant REMP programs and other monitoring stations detected the radioactivity from Japan mainly in the form of airborne iodine-131.

During the week of April 5, 2011, all five (5) of Fermi's air monitoring stations detected radioactivity greater than the MDA at an average airborne gross beta of 7.12E-2 pCi/cubic meter and 8.12E-2 pCi/cubic meter for iodine-131 due to the accident at Fukushima Daiichi Nuclear Power Plant.

During 2011, two hundred and fifty-four (254) particulate air filters and charcoal cartridges were collected and analyzed for gross beta activity and iodine-131 respectively.

The average gross beta for indicator samples was 4.70E-2 pCi/cubic meter and 4.15E-2 pCi/cubic meter for control samples. None of the charcoal filters collected showed detectable levels of iodine-131 greater than the MDA attributable to the operation of Fermi 2. The following table contains the annual average gross beta results of all five sample locations for 2011.

In conclusion, the atmospheric monitoring data are consistent with preoperational and prior operational data and show no adverse long-term trends in the environment attributable to operation of Fermi 2 as illustrated in Figures 2 and 3.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Terrestrial Monitoring Radionuclides released to the atmosphere may deposit on soil and vegetation, and therefore, may eventually be incorporated into the human food chain. To assess the impact of Fermi 2 operations to humans from the ingestion pathway, samples of milk, green leafy vegetables, and groundwater are collected and analyzed for radioactivity. The following sections discuss the type and frequency of terrestrial sampling, analyses performed, and a comparison of 2011 data to previous operational and preoperational data.

Milk Sampling A major pathway in the human food chain is the consumption of milk from grazing animals (dairy cows or goats) due to biological concentration and the short turn around time in this pathway. Milk is collected from one indicator location and one control location semimonthly when animals are in the pasture, and monthly when the animals are on stored feed. The milk is analyzed for iodine-131, gamma emitting radionuclides, and strontium-89/90. At times when milk samples are not available, grass samples are collected at both the control milk sample location and the location where milk is not available. Grass samples are analyzed for iodine-131 and other gamma emitting radionuclides. During 2011, no grass samples were scheduled or collected for the REMP.

Milk sampling began in 1979 during the preoperational program. During this time period, milk samples were analyzed for iodine-131 and other gamma emitting radionuclides. Cesium-137 and naturally occurring potassium-40 were the only radionuclides detected in milk samples during the preoperational program. The cesium-137 concentration averaged 3.60E+0 pCi/liter and is due to past atmospheric nuclear weapons testing. In 1986, after the nuclear accident at Chernobyl, iodine-131 and cesium-137 were detected in both indicator and control milk samples. The average concentration was 3.70E+0 pCi/liter for iodine-131 and 6.60E+0 pCi/liter for cesium-137.

The analysis for strontium-89/90 began in 1988, and strontium-90 is routinely detected in both indicator and control milk samples because of past atmospheric nuclear weapons testing.

During 2011, thirty four (34) milk samples were collected and analyzed for iodine-131, gamma emitting radionuclides, and strontium-89/90. No iodine-131 or strontium-89/90was detected greater than the MDA in any of the samples.

8

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Naturally occurring potassium-40 was detected in both indicator and control samples.

In 1970, the concentration of strontium-90 in Monroe County milk was 6.00E+0 pCi/liter according to the Michigan Department of Health's "Milk Surveillance," Radiation Data and Reports, Vol. 11-15, 1970-1974. Figure 4 shows the calculated radiological decay curve for the 1970 concentration of strontium-90 and the average concentrations since 1988. This graph illustrates that the inventory of strontium-90 in the local environment is decreasing with time and closely follows the calculated decay curve. This supports the determination that the inventory of strontium-90 in the environment is due to fallout from past atmospheric nuclear weapons testing and not the operation of Fermi 2.

Historical Strontium-90 Activity in Local Milk Samples 6.0 0

LIJAverage Sr-90 Activity -- Calculated Decay Figure 4 - Historical Strontium-90 Activity in Local Milk Samples; the concentration of strontium-90 in local milk samples is decreasing with time and is below the calculated decay curve. This supports the fact that strontium-90 in local milk is due to fallout from past atmospheric nuclear weapons testing and not the operation of Fenni 2.

Groundwater Sampling In areas not served by municipal water systems, water supplies for domestic use are generally obtained from private wells. The network of private wells presently in use forms the source of water for domestic and livestock purposes in farms and homes west and north of the site. With the construction of new water plants and distribution systems, the water use trend in the area is from groundwater (local wells) to surface water (municipal water supply).

9

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Groundwater is collected on a quarterly basis from four wells surrounding Fermi 2. The groundwater is analyzed for gamma emitting radionuclides and tritium. Sampling location GW-4, which is located approximately 0.6 miles west northwest, is designated as the control location because it is up-gradient and is least likely to be affected by the operation of the plant. The other three sampling locations are down-gradient from Fermi 2 and designated as indicator locations.

Groundwater sampling began in 1987, during the operational period of the REMP program. From 1987 to 1996, naturally occurring potassium-40, cesium-137, and tritium were detected in both indicator and control samples. The average concentration was 7.71E+0 pCi/liter for cesium-137 and 1.50E+2 pCi/liter for tritium. The presence of cesium-137 and tritium in groundwater samples is due to fallout from past atmospheric nuclear weapons testing leaching into the soil and becoming incorporated into the groundwater. From 1997 to 2008, only naturally occurring potassium-40 activity was detected in groundwater samples.

In 2011, sixteen (16) groundwater samples were collected and analyzed for gamma emitting radionuclides and tritium. During 2011, no samples detected any activity greater than the MDA.

Garden Sampling Fermi 2 collects samples of broad leaf vegetables from indicator locations identified by the annual Land Use Census. Samples are also collected at a control location that is at a distance and direction which is considered to be unaffected by plant operations. Samples are collected once a month during the growing season (June through September) and are analyzed for iodine-131 and other gamma emitting radionuclides.

Vegetable sampling started in 1982. During the preoperational period from 1982 to 1985, only naturally occurring potassium-40 was detected in both indicator and control vegetable samples. During the operational period from 1985 to 1990 and 1994 to 1995, only naturally occurring potassium-40 was detected in both indicator and control vegetable samples. However, in 1991, 1992, and 1993, cesium-137 was detected in one indicator sample each year and had an average concentration of 1.2E+1 pCi/kilogram.

Cesium-137 may become incorporated into plants by either uptake from the soil or direct deposition on foliar surfaces. Since cesium-137 is normally not detected in gaseous effluent samples from Fermi 2, and there have been no recent atmospheric weapons testing or nuclear accidents, the incorporation of cesium-137 by direct deposition is highly unlikely. The most probable source of cesium-137 in vegetable samples is the uptake of previously deposited cesium-137, which has leached into the soil. This cesium activity is attributed to fallout from past atmospheric weapons testing and to the nuclear accident at Chernobyl.

10

Fermi 2 - 2011 Annual Radiological Environmental Operating Report During 2011, ten (10) vegetable samples were collected and analyzed for iodine-131 and other gamma emitting radionuclides. No iodine-131 was detected greater than the MDA in vegetable samples during 2011. The only gamma emitting radionuclide detected were naturally occurring potassium-40and beryllium-7 in both indicator and control samples.

Terrestrial monitoring results for 2011 of milk, groundwater and leafy garden vegetable samples, showed only naturally occurring radioactivity. The radioactivity levels detected were consistent with levels measured prior to the operation of Fermi 2 and no radioactivity attributable to activities at Fermi 2 was detected greater than the MDA in any terrestrial sample. In conclusion, the terrestrial monitoring data show no adverse trends in the terrestrial environment.

Aquatic Monitoring Lake Erie, on which Fermi 2 borders, is used as a source for drinking water, as well as for recreational activities such as fishing, swimming, sunbathing, and boating. For this reason, Lake Erie and its tributaries are routinely monitored for radioactivity.

The aquatic monitoring portion of the REMP consists of sampling raw municipal drinking water, surface water, lake sediments, and fish for the presence of radioactivity.

The following sections discuss the type and frequency of aquatic sampling, analyses performed, and a comparison of 2011 data to previous operational and preoperational data.

Drinking Water Sampling Fermi 2 monitors drinking water at one control location and one indicator location using automatic samplers. The automatic samplers collect samples at time intervals that are very short (hourly) relative to the sample collection period (monthly) in order to assure that a representative sample is obtained. Indicator water samples are obtained at the Monroe water intake located approximately 1.1 miles south of the plant. Detroit municipal water is used for the control samples and is obtained at the Allen Park water intake located approximately 18.6 miles north of the plant. Drinking water samples are collected on a monthly basis and analyzed for gross beta, strontium-89/90, and gamma emitting radionuclides. The monthly samples for each location are combined on a quarterly basis and analyzed for tritium activity.

11

Fermi 2 - 2011 Annual Radiological Environmental Operating Report In late 1980, as shown in Figure 5, an atmospheric nuclear weapon test was conducted by the People's Republic of China. As a result of this test, the average gross beta for 1981 was 9.80E+0 pCi/liter for water samples. Figure 5 also shows that, except for the Chinese weapons testing, the historic drinking water sample data are below or slightly above the lower limit of detection (4.00E+0 pCi/liter) required by US Environmental Protection Agency (USEPA) National Interim Primary Drinking Water regulations. Even during the Chinese weapons testing, the drinking water samples did not exceed the USEPA maximum allowable criteria of 5.00E+1 pCi/liter gross beta. In 1980 and 1983, cesium-137 was detected in drinking water samples at levels ranging from 5.40E+0 pCi/liter to 1.90E+1 pCi/liter. Tritium was also detected during the preoperational program and had an average of 3.25E+2 pCi/liter. The presence of cesium-137 and detectable levels of tritium in these water samples is due to fallout from past atmospheric nuclear weapons testing and naturally occurring tritium.

From 1985 to 2010, the average annual gross beta activity for indicator samples was 4.09E+0 pCi/liter and 3.46E+0 pCi/liter for control samples. The analysis for strontium-89/90 began in 1988, and strontium-90 has in the past been detected in both indicator and control samples. The average strontium-90 activity for indicator samples was 7.25E-1 pCi/liter and 7.56E-1 pCi/liter for control samples during this time period. Tritium was also detected in both indicator and control drinking water samples during this time period.

The average tritium activity for indicator samples was 2.52E+2 pCi/liter and 2.60E+2 pCi/liter for control samples. The presence of strontium-90 and detectable levels of tritium in these water samples is due to fallout from past atmospheric nuclear weapons testing and naturally occurring tritium.

In 2011, twenty-four (24) drinking water samples were collected and analyzed for gross beta, gamma emitting radionuclides, strontium-89/90, and tritium. Gross beta activity was detected in one indicator sample at 6.38E+0 pCi/liter and one control sample at 5.72E+0 pCi/liter. Naturally occurring potassium-40 was detected in one indicator sample. No strontium-89/90 activity was detected greater than the MDA in drinking water samples during 2011. Eight (8) quarterly composite drinking water samples were prepared and analyzed for tritium. No tritium activity was detected greater than the MDA in drinking water samples during 2011.

Since 1982, the annual concentrations of beta emitting radionuclides in drinking water samples collected from indicator locations have been consistent with those from control locations.

This shows that Fermi 2 has had no measurable radiological impact on local drinking water.

Surface Water Sampling Fermi 2 monitors surface water at two locations using automatic samplers. As with drinking water, surface water samples are collected at time intervals that are very short (hourly) relative to the sample collection period (monthly) in order to assure obtaining a representative sample. Indicator surface water samples are obtained at the Fermi 2 General Service Water building, located approximately 0.3 miles south southeast from Fermi 2. The control surface water samples are obtained from Trenton Channel Power Plant's cooling water intake on the Detroit River, which is approximately 11.7 miles north northeast of Fermi 2. Surface water samples are collected on a monthly basis and analyzed for strontium-89/90 and gamma emitting radionuclides. The monthly samples for each location are combined on a quarterly basis to form a quarterly composite sample and are analyzed for tritium.

13

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Surface water sampling began in 1979, and the samples were analyzed for gamma emitting radionuclides and tritium. During this preoperational program, no gamma emitting radionuclides, except for naturally occurring potassium-40, were detected.

Tritium was detected in both indicator and control samples during this time period and had an average concentration of 3.15E+2 pCi/liter. This tritium activity represents the background concentration due to naturally occurring tritium and tritium produced during past atmospheric nuclear weapons testing.

From 1985 to 2010, as part of the operational program, surface water samples were analyzed for gamma emitting radionuclides and tritium. The analysis for strontium-89/90 did not begin until 1988, and strontium-90 was detected in both indicator and control samples. The average strontium-90 concentration for this time period was 1.13E+0 pCi/liter. In 1990, two indicator samples showed detectable activity for cesium-137 at an average concentration of 1.20E+1 pCi/liter. The presence of cesium-137 and strontium-90 in these water samples is due to fallout from past atmospheric nuclear weapons testing. Tritium was detected in both indicator and control surface water samples during this time period at a concentration of 2.31E+2 pCi/liter. This tritium activity is consistent with background levels measured during the preoperational program.

In 2011, twenty-four (24) surface water samples were collected and analyzed for gamma emitting radionuclides and strontium-89/90. From these samples, eight (8) quarterly composite samples were prepared and analyzed for tritium. During 2011, no gamma emitting radionuclides, strontium-89/90 or tritium was detected greater than theMDA in surface water samples.

Sediment Sampling Sediments often act as a sink (temporary or permanent) for radionuclides, but they may also become a source, as when they are resuspended during periods of increased turbulence or are dredged and deposited elsewhere. Sediment, in the vicinity of the liquid discharge point, represents the most likely site for accumulation of radionuclides in the aquatic environment, and with long-lived radionuclides, a gradual increase in radioactivity concentration would be expected over time if discharges occur. Sediment, therefore, provides a long-term indication of change that may appear in other sample media (i.e., water and fish samples).

14

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Lake Erie shoreline and bottom sediments from five locations are collected on a semiannual basis (Spring and Fall) and are analyzed for gamma emitting radionuclides and strontium-89/90. There is one control location and four indicator locations. The control sample is collected near the Trenton Channel Power Plant's cooling water intake.

The indicator samples are collected at Estral Beach, north of the Fermi 2 liquid discharge area, the shoreline at the end of Pointe Aux Peaux, and Indian Trails Community Beach.

During the preoperational program, there was not a control location, and indicator samples were analyzed for gamma emitting radionuclides. During the preoperational program, except for naturally occurring radionuclides, only cesium-137 was detected in sediment samples. For this time period, the average cesium-137 concentration was 3.27E+2 pCi/kilogram. The presence of cesium-137 in these sediment samples is due to fallout from past atmospheric nuclear weapons testing.

From 1985 to 2010, cesium-137, strontium-90, and naturally occurring radionuclides were detected in sediment samples. The average cesium-137 concentration was 1.22E+2 pCi/kilogram for all samples. The analysis for strontium-89/90 began in 1988, and strontium-90 has been routinely detected at similar concentrations in both indicator and control samples. The average strontium-90 activity for indicator samples was 1.80E+2 pCi/kilogram and 1.98E+2 pCi/kilogram for control samples. The presence of cesium-137 and strontium-90 in these sediment samples is due to fallout from past atmospheric nuclear weapons testing.

In 1990 and 1991, the Spring samples taken at the Fermi 2 liquid discharge line (Location S-2) showed activity for plant related radionuclides (manganese-54, cobalt-58, cobalt-60, and zinc-65) and was determined to be a result of liquid effluent from Fermi 2. The sample results were well below any regulatory reporting limits and were consistent with the activity released from the plant in liquid effluents as per the approved effluent program. The dose impact was negligible due to these effluents.

In 2011, ten (10) sediment samples were collected and analyzed for gamma emitting radionuclides and strontium 89/90. Cesium-137 was detected in one control sample with a concentration of 1.00E+2 pCi/kilogram. The presence of cesium-137 in sediment samples is due to fallout from past atmospheric nuclear weapons testing. Naturally occurring radionuclide potassium-40 was also detected in both indicator and control sediment samples for this sampling period.

As the calculated trend shows, the concentration of cesium-137 in Lake Erie sediments is decreasing with time. This supports the fact that cesium-137 in Lake Erie sediments is due to fallout from past atmospheric nuclear weapons testing and not the operation of Fermi 2.

Figure 6 shows the historical concentration of cesium-137 in sediment samples from 1978 to 2011. Using the data from these years, and the statistical method of least squares, an exponential curve can be calculated that represents the cesium-137 concentration in sediment. This curve has a negative slope which indicates the overall concentration of cesium-137 in the environment is decreasing with time. This supports the fact that the inventory of cesium-137 in the environment is due to fallout from past atmospheric nuclear weapons testing and not from the operation of Fermi 2.

Fish Sampling Samples of fish are collected from Lake Erie at three locations on a semiannual basis.

There are two control locations and one indicator location. The two control locations are offshore of Celeron Island and in Brest Bay. The indicator location is approximately 1200 feet offshore of the Fermi 2 liquid effluent discharge. Edible portions of the fish are analyzed for gamma emitting radionuclides and strontium-89/90.

During the preoperational program, fish samples were analyzed for gamma emitting radionuclides. Only cesium-137 and naturally occurring potassium-40 were detected during this time period. The average concentration of cesium-137 for indicator samples was 3.53E+1 pCi/kilogram and 4.20E+1 pCi/kilogram for control samples. The presence of cesium-137 in these fish samples is due to fallout from past atmospheric nuclear weapons testing.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report From 1985 to 2010, cesium-137 and naturally occurring potassium-40 were detected in fish samples. The average cesium-137 concentration for indicator samples was 3.82E+1 pCi/kilogram and 3.92E+1 pCi/kilogram for control samples. The analysis for strontium-89/90 began in 1990, and strontium-90 was routinely detected at similar concentrations in both indicator and control samples. The average strontium-90 concentration for indicator samples was 3.84E+1 pCi/kilogram and 3.15E+1 pCi/kilogram for control samples. The presence of cesium-137 and strontium-90 in these fish samples is due to fallout from past atmospheric nuclear weapons testing.

In 2011, twenty-four (24) fish samples were collected and analyzed for gamma emitting radionuclides and strontium-89/90. Only naturally occurring potassium-40 was detected in both control and indicator fish samples for 2011.

Aquatic monitoring results for 2011 of water, sediment, and fish showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and were consistent with levels measured prior to the operation of Fermi 2. In conclusion, no radioactivity attributable to activities at Fermi 2 was detected greater than the MDA in any aquatic sample during 2011 and no adverse long-term trends are shown in the aquatic monitoring data.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Land Use Census The Land Use Census is conducted in accordance with the Fermi 2 Offsite Dose Calculation Manual (ODCM), control 3.12.2, and satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. This census identifies changes in the use of unrestricted areas to permit modifications to monitoring programs for evaluating doses to individuals from principal pathways of exposure. The pathways of concern are listed below:

" Inhalation Pathway - Internal exposure as a result of breathing radionuclides carried in the air.

" Ground Exposure Pathway - External exposure from radionuclides deposited on the ground.

" Plume Exposure Pathway - External exposure directly from a plume or cloud of radioactive material.

Vegetation Pathway - Internal exposure as a result of eating vegetables which have absorbed deposited radioactive material or which have absorbed radionuclides through the soil.

" Milk Pathway - Internal exposure as a result of drinking milk which may contain radioactive material as a result of dairy animals grazing on a pasture contaminated by radionuclides.

" Meat Pathway - Internal exposure as a result of consuming meat which may contain radioactive material as a result of animals grazing on a pasture contaminated by radionuclides.

The Land Use Census is conducted during the growing season and is used to identify, within a radius of 5 miles, the location of the nearest residences, milk animals, meat animals, and gardens (greater than 50 square meters and containing broad leaf vegetation) in each of 16 meteorological sectors surrounding Fermi 2. Gardens greater than 50 square meters are the minimum size required to produce the quantity (26 kg/year) of leafy vegetables assumed in NRC Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 20% of the garden is used for growing broad leaf vegetation (i.e., lettuce and cabbage); and (2) a vegetation yield of 2 kg/square meter.

Fermi 2 - 2011 Annual Radiological Environmental Operating Report 2011 Land Use Census Results The Land Use Census is conducted in accordance with ODCM control 3.12.2 and satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. This census identifies changes in the use of unrestricted areas to permit modifications to monitoring programs for evaluating doses to individuals from principal pathways of exposure. The annual Land Use Census is conducted during the growing season and is used to identify, within a radius of 5 miles, the location of the closest residences, milk animals, meat animals, and gardens in each of the 11 land based meteorological sectors surrounding Fermi 2.

The 2011 Land Use Census was performed during the month of August. The 2011 census data were obtained with the use of Global Positioning System (GPS) equipment.

These data were compared to the 2010 data to determine any significant changes in the use of the land. The results of the census are tabulated in Tables 2 - 5 of this report.

No significant changes in the land use between 2010 and 2011 were found that would require changing the location of the "maximum exposed individual." There were no changes in the category of closest residences. There were slight changes in the meteorological sectors in the category of closest gardens. The changes were identifying slightly closer gardens in a few sectors. See Table 3 for these changes. The "maximum exposed individual" is located in the West-North-West sector and at one time participated in the REMP program. In the past few years this location did not have a garden, but in 2007-2008 a garden was planted at this location. In the category of closest milk locations, there were no changes. All milk locations that were identified are pets and, any milk produced, is not use for human consumption. There were no changes found in the category of closest meat locations. As with past surveys, this census identified new residential housing construction that shows a continuing trend of converting agricultural land to other uses in the area surrounding Fermi 2.

As stated above, there were no significant changes in the 2011 land use that would require changing the location of the "maximum exposed individual." For that reason, the location of "maximum exposed individual" remains the same and is described as follows:

Appendix D Environmental Program Exceptions

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Environmental Program Exceptions On occasions, samples cannot be collected. This can be due to a variety of events, such as equipment malfunction, loss of electrical power, severe weather conditions, or vandalism. In 2011, missed samples were a result of missing field TLDs and air sampling equipment failure. The following sections list all missed samples, changes and corrective actions taken during 2011. These missed samples did not have a significant impact on the execution of the REMP.

Direct Radiation Monitoring All TLDs are placed in the field in inconspicuous locations to minimize the loss of TLDs due to vandalism. During 2011, three hundred sixteen (316) TLDs were placed in the field for the REMP program and all but five (5) TLDs were collected and processed.

" During the first quarter collection T-14, T-48, and T-62 were found missing and were replaced with the next quarter's TLDs.

During the second quarter collection T-14 and ISFSI-1 were found missing and were replaced with the next quarter's TLDs.

Atmospheric Monitoring During 2011, two hundred fifty-five (255) air samples were placed in the field and all but one (1) particulate filter and charcoal filter was collected and processed. There were no changes to the Atmospheric Monitoring program during 2011.

" On 1/18/2011, air sample located at API-4 was not collected due to fuse failure. The fuse was replaced and the equipment was reenergized. For this reason, the first quarter composite sample is considered less than representative.

On 3/22/2011, 4/5/2011, and 4/12/2011, iodine-131 was detected at API-1 due to the Fukushima accident.

" On 4/5/2011, iodine-131 was detected at API-2 due to the Fukushima accident.

Appendix E Interlaboratory Comparison Data GEL Laboratories' Quality Assurance Programs

Fermi 2 - 2011 Annual Radiological Environmental Operating Report Interlaboratory Comparison Program for 2011 In an interlaboratory comparison program, participant laboratories receive from a commerce source, environmental samples of known activity concentration for analysis.

After the samples have been analyzed by the laboratory, the manufacturer of the sample reports the known activity concentration of the samples to the laboratory. The laboratory compares its results to the reported concentrations to determine any significant deviations, investigates such deviations if found, and initiates corrective action if necessary. Participation in this program provides assurance that the contract laboratory is capable of meeting accepted criteria for radioactivity analysis. The following is GEL Laboratories' participation in an interlaboratory comparison program.

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.

Management's 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 GEL's 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.

GEL's 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. GEL's 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 2010. GEL's 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 2010.

" Inter-laboratory QC results analyzed during 2010 where known values were available.

Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 6 of 51

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.

" ERA's 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.

" ERA's 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

Laboratories LLc P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 7 of 51 emitters, Gross Alpha/Beta, Iodine-131, naturally occurring radioactive isotopes, Strontium-89/90, and Tritium.

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

o ERA's Water Supply (WS) biannual program for drinking water methodologies includes parameters for organic and inorganic analytes.

New York State Department of Health Environmental Laboratory Approval Program Proficiency Testing Program for Potable Water (PW)

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. GEL's 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 GEL's clients.

3. Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-E001. The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's 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 (10-RAD-001) was conducted in March 2010. Four findings, one observation, and two recommendations resulted from this assessment. Each finding was closed and appropriate laboratory staff addressed each observation and recommendation. The internal audit closed in June 2010.

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 GEL's 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 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 GEL's 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 GEL's 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

E "iLaboratories LLc P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 9 of 51 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 GEL's clients.

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.

GEL's 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.

GEL's 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 (%) = (hiqh duplicate result - low duplicate result)

100 %

(average of results)

7. Summary of Data Results During 2010, forty-three radioisotopes associated with six matrix types were analyzed under GEL's Performance Evaluation program in participation with ERA, MAPEP, NYSDOH ELAP and Eckert & Ziegler Analytics. Matrix types were representative of client analyses performed during 2010. The list below contains the type of matrix evaluated by GEL.

These graphs include radioisotopes Cobalt-60, Cesium-137, Tritium, Strontium-90, Gross Alpha, Gross Beta, and lodine-131. A summary of GEL's quality control for radiological analyses by isotopic analysis and matrix are represented in Table 8. Each LCS and DUP represents a batch of samples for each isotopic analysis. This summary contains the number of reportable quality control results for our clients.

8. Summary of Participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program During 2010, Eckert & Ziegler Analytics provided samples for 106 individual environmental analyses. Of the 106 analyses, 99% (105 out of 106) of all results fell within the PT provider's acceptance criteria. The only analytical failure occurred with the analysis of Iron-59 in milk. For the corrective action associated with the Iron-59 failure, refer to CARR110209-542 (Table 9).

9. Summary of Participation in the MAPEP Monitoring Program During 2010, one set of MAPEP samples (MAPEP 22) was analyzed by the laboratory. Of the 66 analyses, 80% (53 out of 66) of all results fell within the PT provider's acceptance criteria. Thirteen analytical failures occurred: Plutonium-238 in water, Uranium-235 in filter, Uranium-238 in filter, Uranium-Total in filter, Americium-241 in filter, Cesium-134 in filter, Cesium-137 in filter, Cobalt-60 in filter, Manganese-54 in filter, Plutonium-239/240 in filter, Uranium-244/243 in filter, Uranium-238 in filter, and Uranium-238 in vegetation.

For the corrective action associated MAPEP 22, refer to CARR100617-496 (Table 9). The ICP-MS analysis of Uranium-235 and Uranium-238 failure was attributed to the use of the less vigorous digestion method (EPA Method 3050B). After contacting RESL, GEL discovered that they had used a more rigorous total dissolution process. The failure for Plutonium-238 was attributed to a data reviewer's error and lack of attention to detail to the region of interest that was not included in the data result. Approximately 400 additional counts should have been included. For the remaining isotopic failures, the error was attributed to analyst error and failure to follow the instructions from the PT provider.

10. Summary of Participation in the ERA MRaD PT Program During 2010, the ERA MRad program provided samples (MRAD-12 and MRAD-13) for 175 individual environmental analyses. Of the 175 analyses, 96% (169 out of 176) of all results fell within the PT provider's acceptance criteria. Six analytical failures occurred: Uranium-234 in soil, Uranium-238 in soil, Uranium-238 in vegetation, Plutonium-238 in water, Uranium-238 in water, and Bismuth-212 in soil.

GEL Laboratories LLc P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 11 of 51 For the corrective actions associated with MRAD 12 and MRAD-13, refer to corrective actions CARR100617-497 and CARR101210-527, respectively (Table 9). For MRAD-12, the ICP-MS analysis of Uranium-235 and Uranium-238 failure was attributed to the use of the less vigorous digestion method (EPA Method 3050B). After contacting RESL, GEL discovered that they had used a more rigorous total dissolution process. For Uranium-238 in vegetation, air and water, the failure was attributed to method sensitivity by gamma spectroscopy. Future PT analysis will be performed using a more sensitive method.

For MRAD-13, the failure for Bismuth-212 was attributed to a reporting error. The actual result (1660 pCi/kg) was within the acceptance range. The failure of Iron-55 was attributed to matrix interference. An additional recount with a smaller aliquot and fresh reagent rinses removed the interferant.

11. Summary of Participation in the ERA PT Program During 2010, the ERA program provided samples (RAD-80 and RAD-82) for 53 individual environmental analyses. Of the 53 analyses, 77% (41 out of 53) of all results fell within the PT provider's acceptance criteria. Twelve analytical failures occurred: Strontium-89 in water, Strontium-90 in water, Barium-133 in water, Cesium-134 in water, Cesium-137 in water, Cobalt-60 in water, Zinc-65 in water, Uranium (Natural) in water, Uranium (Nat) Mass in water, Strontium-90 in water, Cesium-134 in water, and Zinc-65 in water.

For the corrective actions associated with RAD-80 and RAD-82, refer to corrective actions CARR100318-487 and CARR100907-512, respectively (Table 9). For RAD-80, the Gross Alpha failure was attributed to a concentrated iron carrier. The Strontium-89 and Strontium-90 failures were attributed to the associated weights of the carriers utilized during the preparation and analysis.

For RAD-82, failures of the Gamma Emitters and the Naturals (Uranium) were attributed to analyst error and failure to follow the instructions from the PT provider. The failure of Strontium-89 and Strontium-90 was attributed to analyst error while diluting the sample.

12. Summary of Participation in the New York ELAP PT Program During 2010, the NYSDOH ELAP PT program provided 30 individual tests for radiological analysis. Of the 30 analyses, 83% (25 out of 30) of the results were within the PT provider's acceptance criteria. Five analytical failures occurred: Cesium-134 in water, Iodine-131 in water (two), Strontium-89 in water, and Radium-226 in water.

For the corrective actions associated with NY-337, refer to corrective action CARR101203-525 (Table 9). For Cesium-134, lodine-131, Strontium-89 and Strontium-90, and Radium-226, the failures could not be determined. The laboratory continues to monitor results of internal quality control samples.

In addition, GEL (Lab ID# E87156, Lab Code# S000012) maintained primary NELAP accreditation from the Florida Department of Health for the following methods in potable water and non-potable water. The radiological analytes and methods are listed below.

13. Quality Control Program for REMP Analyses GEL's internal (intra-laboratory) quality control program evaluated 1590 individual analyses for bias and 1591 analyses for precision for standard REMP matrix and radionuclides. Of the 959 internal quality control analyses evaluated for bias, 100% met laboratory acceptance criteria. In addition, 100% of the 1591 results for precision were found to be acceptable. The results are summarized in Table 8.

GEL performs low-level analysis specifically for Tritium in water. A chart of low activity H-3 spike performance is provided in Figure 8. All 2010 analyses were within the acceptance criteria.

14. 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.

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 laboratory's 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 9 provides the status of CARRs for radiological performance testing during 2010.

SUMMARY

GEL CORRECTIVE STATUS:

ACTION IDENTIFICATION OPEN/ ISSUE Cause and Disposition CLOSED CARR110209-542 OPEN Eckert & Ziegler Analytics Monitoring in progress Fe-59 Failure in Milk CARR100617-496 CLOSED MAPEP Series 22 PT The ICP-MS analysis of Uranium-235 Failures and Uranium-238 failure was attributed to the use of the less vigorous digestion method (EPA Method 3050B). After contacting RESL, GEL discovered that they had used a more rigorous total dissolution process.

The failure for Plutonium-238 was attributed to a data reviewer's error and lack of attention to detail to the region of interest that was not included in the data result. Approximately 400 additional counts should have been included. All analysts have been retrained on attention to detail of the ROI.

For the remaining isotopic failures, the error was attributed to analyst error and failure to follow the instructions from the PT provider.

CARR100617-497 CLOSED MRAD 12 PT Failures The ICP-MS analysis of Uranium-235 and Uranium-238 failure was attributed to the use of the less vigorous digestion method (EPA Method 3050B). After contacting RESL, GEL discovered that they had used a more rigorous total dissolution process.

For Uranium-238 in vegetation, air and water, the failure was attributed to method sensitivity by gamma spectroscopy. Future PT analysis will be performed using a more sensitive method.

CARR101210-527 CLOSED MRAD 13 PT Failures The failure for Bismuth-212 was attributed to a reporting error. The actual result (1660 pCi/kg) was within the acceptance range. The failure of Iron-55 was attributed to matrix interference. An additional recount with a smaller aliquot and fresh reagent rinses removed the interferant.

Laboratories LLc P.O. Box 30712, Charleston, SC 29417 2010 ANNUAL QUALITY ASSURANCE REPORT Page 51 of 51 CARR100318-487 CLOSED RAD-80 PT Failures The Gross Alpha failure was attributed to a concentrated iron carrier. The Strontium-89 and Strontium-90 failures were attributed to the associated weights of the carriers utilized during the preparation and analysis.

CARR100907-512 CLOSED RAD-82 PT Failures Failures of the Gamma Emitters and the Naturals (Uranium) were attributed to analyst error and failure to follow the instructions from the PT provider. The failure of Strontium-89 and Strontium-90 was attributed to analyst error while diluting the sample. All analysts were retrained to the proper processes.

CARR101203-525 CLOSED NY-337 PT Failures For Cesium-134, Iodine-131, Strontium-89 and Strontium-90, and Radium-226, the failures could not be determined. The laboratory continues to monitor results of internal quality control samples.
