From land, lake or air the cooling towers of Detroit Edison's Fermi 2 nuclear power plant are a clearly visible landmark in Monroe County, Michigan. These towers symbolize the important economic and environmental benefits of nuclear energy-America's second largest source of electric power.
Without this clean method of generating electricity, many of us might literally be in the dark. Yet in terms ofpublic awareness ofwhar nuclear energy is and why it's important, many people are in the dark.
Popular misconceptions, fear of the unknown, and lack of basic information unnecessarily cloud the plant towers in mystery. But when the facts are laid out, they reveal the critical importance of this U.S.
energy resource.
You'll fmd detailed information on nuclear energy and the Fermi 2 power plant in this report. The following pages detail the facts: the key role of nuclear power in the U.S. energy agenda, why Fermi 2 was cons:ucted, how it operates and the benefits it provides to Monroe County. A summary of the 1993 tu < nmental monitoring program which measures Fermi 2's impact on the surrounding environment is also provided.

Fermi 2- 1993 Annual RadiologicalEnvironmental Afonitoring Report What is the importance ofnuclear energy?
One of the major reasons why nuclear energy is so important to our quality oflife is that it helps preserve our country's energy independence.
Only thirty years ago, nuclear energy was a developmental futuristic technology-the essence ofscience fiction, it seemed. Yet today, approximately 109 nuclear power plants around the country provide more electricity than oil, natural gas or hydropower technologies.
Detroit Edison contributed heavily to the early history of nuclear power development through the design, construction and opei. tion of Fermi 1.

l Helpingsustain economicgrowth l        Studies show that U.S. economic growth has been fueled largely by electric power. There is a close and continuing connection between the growth of the economy and the supply of electricity. Nuclear energy is an important contributor to mainnining the electric power necessary to launch successful business start-ups and maintain industrial strength. Electricity is so essential to our way oflife that we l        take it for granted.
Protecting the environment l        Nuclear energy has helped create a cleaner environment throughout the world. Nuclear power plants produce electricity by splitting uranium atoms, not by burning fuels. That's why they don't pollute the air with dust and emissions ofgreenhouse gases (like carbon dioxide) that occur from other sources such as coal, natural gas or oil. France, for example, tripled its nuclear energy production during the 1980s in response to concerns about imported oil. During that same period, overall pollution from the French electric power system dropped 80 to 90 percent.
Meeting the needs ofa growingpopulation The demand for electricity is growing as the population increases. Since the 1973 oil embargo, the U.S.
population grew from 212 million to 250 million and electricity demand rose 61 percent. The U.S.
Department of Energy (DOE) projects that our need for electricity will increase 24 percent between 1989 and the year 2000, and 51 percent by 2010. Nuclear power plants will be an important part of meeting that need.
The outlook for nuclear energy is still good. In the decades to come, nuclear energy will play a major role in " electrifying" our economy while also protecting our environment.

Fmni2- 1993 Annual bd;ohgical Environmental Monitoring Report The History ofFermi2 The history of the Enrico Fermi Atomic Power Plant Unit 2, known as " Fermi 2," began in the late 1960s. Its purpose was twofold: (1) to meet the fast-growing demand for electricity in southeastern Michigan, and (2) to provide the region with a diversity of fuels for generating electricity.
Site selection In 1968, Detroit Edison announced plans to construct Fermi 2 along the western shore of Lake Erie in Frenchtown Township. This location was selected for its suitability in maintaining an efficient, cost-effective supply ofelectricity for the some five million people then in Detroit Edison's service area.
Additionally, a nuclear power plant would pose none of the environmental disadvantages to this beautiful area that are associated with other power supplies.
A challenging course The development of Fermi 2, from its inception in 1968 to its commencement of operations in 1985, followed a course full of challenges arising from the turbulent economic, technological and regulatory changes of that period. The primary driving force in this story was the visionary leader Walker L Cisler, CEO of Detroit Edison (1954-1971) and later board chairman (1964-1975). Cisler foresaw the need for nuclear power in an expanding economy's increasing demand for electricity. His organizational and managerial skill translated vision into action as he attracted top-caliber nuclear engineers for the project management team.
The chief goals set by Detroit Edison in constructing Fermi 2 were to design and build a safe, reliable plant at a reasonable cost. But the company ran into unforeseen events that slowed construction and sharply boosted costs. In the 1970s, newly established federal regulatory agencies and environmental policies, combined with rigorous self-regulation in the utilities industry, triggered combined delays of five to six years in licensing and construction. But Detroit Edison persisted in its commitment for long-term growth and securing the economic and environmental health of southeastern Michigan.

Detroit Edison continues to be a visionary leader in taking a proactive role in environmental issues and providing industry leadership in radioactive source term reduction. For example, in 1993 the radiation dose due to radioactive emuents discharged from Fermi 2 was less than one percent of federal limits.
Detroit Edison also has taken an active role in wildlife management in a cooperative program ofwildlife habitat restoration with the Wildlife Division of the Michigan Department of Natural Resources, Detroit Edison maintains a two-acre site for raising Sichuan/ ringneck pheasants that are released throughout southeastern Michigan.

The benefits of nuclear energy production to the public often are hidden behind an inadequate understanding of how nuclear power plants work. Basically, nuclear plants function like coal, oil and gas power plants by using heat to boil water into steam, which in turn spins a turbine that drives an electric generator.
The only difference between nuclear and conventional power plants is the element used to generate heat: instead of burning coal, oil or gas, nuclear plants split atoms of uranium in a chain reaction called
      " fission" that releases tremendous amounts of heat. This splitting, or fission, takes place inside a large containment vessel called a reactor (at Fermi 2, a " boiling water" reactor rather than a " pressurized water" reactor-the difference lies simply in how the water is brought to a boil).
1 How the heat is generated and collected                                                                                                              1 As shown above, the reactor (1), surrounded by steel-reinforced concrete,is carefully designed to trigger and control the atomic reaction and capture the resulting heat. At the center of the reactor vessel, ceramic pellets of uranium fuel are stacked inside twelve-foot-long tubes, or " fuel rods," made of zirconium alloy and spaced in bundles. Inserted between the fuel rods are " control rods," made of a special material that controls the speed of the nuclear reaction.
These rod assemblies are encased in a six-inch thick steel pressure vessel, which in turn is encased in the massive steel-reinforced concrete containment structure of the reactor building. When water is circulated through the reactor, the heat it collects from the fissioning uranium atoms causes it to boil.

Fermi 2- 1993 Annual RadiologicalEnvironmental Monitoring Report The resulting steam travels at high pressure to the turbine (2). The force of the steam spins the turbine like a high-speed windmill, which in turn cpins the rotor of the electric generator. The electricity that l
is generated is then transmitted to substations and eventually out to distribution circuits, which feed the demands of the homes, farms, and businesses of southeastern Michigan.
After the steam loses much ofits energy by spinning the turbine, it passes through the condenser (3),
where it is cooled and converted back to a liquid. Once the steam has cooled and condenses back into water, it is pumped back through the reactor to collect heat again.
i The cooling water in the condenser travels a separate path from the water pumped through the reactor.
This cooling water is pumped from a 30-million-gallon reservoir to the condenser, where it picks up heat as it does its job of cooling the steam returning from the turbine. The cooling water releases this l
excess heat as water vapor that looks like steam when it is pumped to the cooling towers (4). Once it has cooled to its original form as water, it is pumped back to the reservoir.
l
  $1C C00l5Hg !OWCTS Many people wonder whether the water vapor emitted by the cooling towers of Fermi 2 is radioactive.
The simple explanation above of how Fermi 2 works reveals that it is nm radioactive, because the water I
vapor is only from the cooling water, not the water circulated through the teactor. The design and operation of Fermi 2 do not permit the cooling water ever to come in contact with the steam from the reactor. Therefore, the plumes you see above the cooling towers are water vapor-like watching your breath come out in puffs on a cold day.
The next time you see the Fermi 2 cooling towers, think of them as structures designed to process clean water-a far cry from the mistaken v              '
associations with radioactivity still harbored by too many people. The hourglass shape of the Fermi 2 towers facilitates natural convection, as cool air enters at the bottom and rises to the top. This air cools the water pumped into the tower. This efficient process means that the Fermi 2 cooling towers use no energy to circulate air through them, unlike other designs, which do not use convection and therefore must resort to energy-consuming fans to pull the air through.                                        _

Radiation: Shedding Light on Clouded Perceptions Radiation has become a familiar term in recent decades. But that doesn't mean the term is clearly         1 understood. Many perceptions of radiation remain clouded because ofinadequatt understanding of what radiation actually is, where it comes from and the benefits it provides.
Simply defined, radiation is the emission ofenergy from a source, similar to heat from a stove. Radiation is given off by radioactive materials, which have an " unstable" atornic configuration. The unstable atoms undergo a natural process of" decay" in which they emit rays or particles (radiation). Some of the resulting products-the atomic fragments released when the nucleus splits-are themselves radioactive, and some revert to a " stable," nonradioactive state.
Scientists measure radiation exposure in units called millirems. A millirem measures the effect of radiation on our bodies, as degrees measure temperature and inches measure distance.
After more than ninety years ofintensive study, radiation is the most scientifically understood, easily detected and precisely measured, effectively controlled and strictly regulated of all environmental agents. It can be categorized in two types: natural background radiation and man-made radiation.
Naturalbackground radiation Because radiation cannot be detected with our basic human senses (sight, hearing, taste, touch and smell), many people are unaware that the carth is full of naturally occurring radioactivity, called
         " natural background radiation."
For example, we are continually exposed to radiation from radon gas in the air (the biggest single sourceh radioactive potassium in our food and water; radioactive uranium, radium and thorium in the earth's crust; and radioactivity from cosmic rays and from the sun.
1 This natural background radiation makes up neady 85 percent of total annual exposure-an average          ;
of 300 millirem each year for individuals in the United States. The remainder,15 percent, is generated by man-made sources.

1-10 RadiologicalEnvironmental Monitoring Report

Fermi 2- l993 Annual RadiologicalEnvironmental Afonitoring Report Man-made radiation We use radioactive materials in hundreds of beneficial and life-saving ways. For example, many smoke detectors use radioactive materials. Doctors use radiation from X-ray equipment. Nuclear power plants use radioactive material as fuel.
Many people mistakenly distinguish between " natural" and " man-made" radiation, assuming that one is more harmful than the other. But the fact is that radiation is the same, whether it occurs naturally in the environment or is produced by medical or industrial activities.
How radiation afects us Very large amounts of radiation-far above the levels we encounter in daily life-can produce cancer and possible genetic defects. We know this from the few groups of people who have been subjected to large radiation exposures-tens of thousands of millirems and above. These groups include the men I       and women who pioneered medical radiology and survivors of the atomic bombs dropped on
!        Hiroshima and Nagasaki during World War II.
But radiation from natural and man-made sources generally involves little risk. Scientific studies conducted over several decades indicate that exposures below ten thousand millirems have no measurable effect on humans. Primary health effects associated with radiation show no correlaua with low level exposures. At such low radiation levels, the probability of these health efTects follows the same pattern of statistics expected for their occurrence in the general population.

Feroni2- 1993 Annual RadiologicalEnvironmental Moratoring Report Fermi 2 Radiation in Perspective To put this la perspective for people living near Fermi 2, radiation exposure due to radioactive products from nuclear power generation must be considered relative to the radiation expost             from all other sources.
This comparison has been performed by the National Council on Radiation Protection and Measurements (NCRP), an independent body ofexperts on radiation and its efTects on human beings.
The NCRP has established guidelines and recommended limits for human radiation exposure. It uses an " average annual effective dose equivalent" to index comparative radiation exposures from varying sources-in cross-comparison and in relation to established radiation protection standards.
Documented in the publication "NCRP Report No. 93: lonizing Radiation Exposure of the Population of the United States " the NCRP estimates the average annual effective dose equivalent (due to natural background radiation and man-made sources) as 360 millirems for a U.S. resident. This dose, roughly couivalent to 24 chest X-rays, is primarily the result of radon gas continually emitted from the earth.
How much of this dose is attributable to radioactivity from the use of nuclear fuel activity? The NCRP estimates that radiation exposure from nuclear energy accounts for less than one-tenth ofone percent of an average person's annual dose.
Still, many people are concerned that the atomic chain reaction occurring in nuclear power plants might somehow trigger a bomb-like nuclear explosion. Or they assume that radioactivity leaks undetected from nuclear power plants, putting those within the immediate vicinity at great risk. Again, a simple presentation of facts clears these misconceptions.
The barriers to radioactivity at Fermi 2 At Fermi 2, the fission of um            uoms is controlled carefully through the addition or removal of materials that slow the rate of the , '..on reaction. The design makes it impossible for an instantaneous, uncontrolled reaction, such as that which occurs in a nuclear bomb, to take place.
Fermi 2 is engineered and physically constructed to provide multiple barriers against the release of radioactive materials that are the result of fission. There are three primary barriers in the reactor.
Barrier 1 is the nuclear fuel itself. Most of the radioactive fission products never escape from the uranium pellets stacked inside the fuel rods; only a fraction migrate outside the ceramic pellets.

1 Fermi 2- 1993 Annual RadiologicalEnvironmental Monitoring Report Water treatment systems at Fermi 2 collect and store untreated liquid waste from plant buildings.
When water carrying radioactive products leaks from plant piping, for example, it collects and flows into floor drains inside the Fermi 2 buildings. These liquids are routed for processing to various building basins or sumps through an extensive drainage system. The sumps are then pumped to a system carefully designed to filter the water so it can be reused.
As the liquids are collected in large holding tanks, some of the radioactive pmducts decay into non-radioactive forms. After the waste liquid fills one tank, it is pumped through a filter vessel like those used in home water softeners. As the resin attracts certain molecules in the water, it removes most of the impurities-including most of the dissolved and suspended particles which may be radioactive. If any water must be discharged, the waste handling system then mixes the treated water with clean water from the Fermi 2 cooling pond before it goes into Lake Erie. This process renders the concentration of discharged radioactive products close to background radioactivity naturally occurring in the lake.
Air handling systems at Fermi 2 function by controlling and directing the amount of air flow inside Fermi 2 buildings. As some of the water leaking from pipelines evaporates, radioactive products may become airborne. The air handling systems allow Detroit Edison personnel to monitor the amount of radioactivity in the air stream.
Normal operation of the plant creates another source ofairborne radioactivity, namely radioactive gases created inside the reactor core. These gaseous byproducts are carried out of the reactor with the steam, l
flowing through the turbine and into the condenser. As the gases accumulate in the air space of the condenser, they must be continuously pumped out. Otherwise, they would prevent the condenser from working properly, just as your car would not work very long with a plugged exhaust pipe.
The gases are pumped fmm the condenser into a large pipe, designed to require a long time for the gases to travel through it. This is why it's called the " delay pipe." During the long travel through the delay pipe, most of the radioactive gases decay into non-radioactive forms. The gas stream is filtered and then sent through large tanks containing charcoal, which helps remove still more of the radioactive gases.
The gas stream emerging from the other end of the charcoal tanks, which is much less radioactive than the gas stream entering the tanks, is mixed with air taken from the rooms of the plant. The air stream and gas stream mix as they leave the plant through an exhaust pipe on top of the reactor building. The emissions from this exhaust pipe are continuously monitored.

Through these carefully constructed systems for accommodating leaks and treating the flow ofliquids, air circulation and gaseous byproducts through the Fermi 2 plant, Detroit Edison is able to provide a safe working environment for its employees and monitor the low level of radioactivity released into the environment.
To ensure that in generating electricity, nuclear power plants do not expose nearby residents to unacceptable risks, the Nuclear Regulatory Commission imposes strict operating guidelines on liquid and gaseous releases. These guidelines, which are part of the Fermi 2 operating license, limit the dose l        to the most highly exposed population groups to a small fraction of the radiation that occurs from natural background sources. Detroit Edison strictly adheres to these limits while making every effort to release far less than what the limits allow.
Introducing the REMP l        The federal government establishes and the Nuclear Regulatory Commission enforces standards for the emission of radioactive effluents (materials discharged into the environment, generally waste products). Tstle 10 of the Code of Federal Regulations (CFR), Part 50, Appendix I, Section 4.B, requires that Detroit Edison establish an appropriate surveillance and monitoring program to ensure that radioactive products released into the environment are kept at extremely low levels.
Title 10 (Pan 20, Section 1501) also mandates the evaluation of those radioactive efIluents. This evaluation mt.st include an actual physical survey of the locations at which the effluents are discharged along with measurements of the radiation level or concoitration of radioactive products. To comply with these nquirements, Detroit Edison continuously conducts the Radiological Environmental Monitoring Program (REMP). The REMP provides the mechanism to determine whether the levels of radioactivity in the environment around the plant are within established limits and ensures that accumulation of radionuclides in the environment will not become significant as a result of plant operations.

Fermi 2- 1993 Annual RadiologicalEnvironmental Monitoring Report Preoperationalprogram To provide a proper before-and-after picture of the effects of Fermi 2 on the environment, the monitoring program started several years before the Fermi 2 reactor began operating. This preopera-tional environmental monitoring program began acquiring data in 1978 in order to establish a baseline for comparison with later measurements after Fermi 2 began operations.
The preoperational program determined the levels of radiation and radioactive products occurring naturally in the environment near the Fermi 2 reactor. This was done through continuous monitoring and analysis of environmental radiation levels of radioactive products in air, in lake sediment and waters, in drinking water, in milk and in garden vegetables.
Operationalprogram The preoperational program was phased into the operational program in June 1985, when initial criticality was achieved for the Fermi 2 reactor. The elements that made up the preoperational monitoring program are still in effect today. Sampling and analysis of environmental parameters are conducted regularly as well as the continuous monitoring ofenvironmental radioactive products in the environment and changes in radiation levels.
Sampling In the sampling program, samples are regularly collected from designated locations around Fermi 2.
Depending on the rype of samples, collections may be taken on a weekly, monthly, quarterly or semiannual schedule.
Sampling locations within ten miles of Fermi 2 are called " indicator" locations. These sites would be the most likely to indicate if there were any measurable effects in the environment from operation of Fermi 2. Many of the indicator locations have been in the monitoring program since it was established in 1978. Based on the criteria for availability ofsamples. local climate and hydrological conditions, these locations continue to provide acceptable samples for analysis and to allow satisfactory comparison of sample resuhs from year to year.
To provide a way to compare Fermi 2's effect on the environment at close-in locations with conditions at distant locations, samples also are collected from " control locations." These sites, which are at least ten miles from Fermi 2 or farther, are considered outside the area that might be affected by Fermi 2 operations.

l Analysis Analysis ofindicator and control samples is contracted to an independent laboratory. This laboratory       l participates in the Environmental Protection Agency's Interlaboratory Comparison Program to ensure that the lab meets accepted criteria for performing radioactivity analysis. Detroit Edison personnel collect samples from all locations, handling them with extreme care. They follow detailed procedures ensuring that the samples are protected and controlled. The containers are marked with the location, date and type of sample. If necessary, a preservative is added to the sample to ensure that no spoilage will occur during shipment to the laboratory for analysis.
Samples are sent special delivery, so they can be traced if they are not received at the lab within 48 hours. Lab personnel record the date and time the samples were received, along with the type of samples and the analyses required. Once all analyses are completed, the lab reports all results to Fermi 2 for review. Any significant differences in the analyses results between the indicator locations and the control locations must be reported to the NRC.

One of the key features of the REMP is that it continuously monitors the food chain cycle that leads                                                                       i to man by collecting samples from steps along the pathways shown in the illustration above.
Most of us aren't used to thinking about ourselves as part of an " environmental food chain." Yet all of us are part of this chain, as we consume plants or animals that in turn have eaten other plants or animals. Because radioactive products behave just like non-radioactive products in our physical and                                                                        j chemical environments, radioactive products released by the plant may be carried down with the rain, absorbed into the soil or deposited on plants, eaten by grazing animals and passed on to people, or breathed in by animals and people. In this way, radioactive products may become part of the environmental food chain.
1-18 RadiologicalEnrironmental Monitoring Repor

Fermi 2 - 1993 Annual RadiologicalEnvironmental Monitoring Report As precipitation washes material out of the air, radioactive particles settle along with dust and other contaminants. Let's assume the radioactive material settles down on grass. A dairy cow eats the grass.
The radioactive material is concentrated in the cow's body, passing into its milk supply. That milk then is collected for human consumption, and the radioactive product thus reaches people. It is highly unlikely, however, that significant quantities of radioactive products attributable to the operation of Fermi 2 will be passed directly to people from drinking milk.
A similar process takes place when radioactive products settle onto vegetables harvested for human consumption. These milk and vegetation stations along the chain are always considered potential pathways to man because they can be traced directly.
The pathway approach to monitoring radioactivity is also applied to radioactive products released into liquids in the environment. Eating fish and drinking water obtained from Lake Erie are considered the main liquid pathways to man in the local food chain.
It is highly unlikely, however, that significant quantities of radioactive products attributable to the operation of Fermi 2 will be paned directly to people through eating fish. The transmission of significant quantities ofradioactive products through the supply ofdrinking water is similarly unlikely.
The water intake for the city of Monroe, for example, is approximately one mile south of Fermi 2.
By sampling fish, lake water, drinking water, milk and vegetables, Detroit Edison can monitor the
  " Pathways to Man" to estimate any possible exposure resulting from radioactive products released into the environment by Fermi 2.

Direct radiation monitoring l
Still another way the impact of Fermi 2 on the environment is analyzed, is through measurement of direct radiation. You may have noticed small fixtures on utility poles in the vicinity of the Fermi 2 plant.
These fixtures contain measuring devices called "Thermoluminescent Dosimeters" (TLDs). Detroit Edison uses TLDs because they are among the simplest and most reliable indicators of general levels of radiation in the environment.
TLDs, which are about the size of a match box, are extremely sensitive to gamma radiation. Before they can be used in the field, they must be subjected to strict NRC testing requirements. TLDs are located in the area surrounding Fermi 2 to monitor gaseous radioactivity and direct radiation resulting from the plant's operation. As an independent check on the information gathered by these TLDs, the NRC also maintains its own TLDs at approximately the same locations as the Fermi TLDs. Consistently, data from the NRC TLDs has shown approximately the same results as data from the Fermi 2 TLDs.

Fermi 2- 1993 Annual RadiologicalEnvironmental Monitoring Report Ewcutive Summmy The Annual Radiological Environmental Monitoring Report is a detailed report on the Radiological Environmental Monitoring Program (REMP) conducted at Detroit Edison's Fermi 2 Power Plant from January 1 through December 31,1993.
In 1993, more than 900 environmental samples were collected for the REMP. These samples represented direct radiation; atmospheric, terrestrial, and aquatic environments; and Lake Erie surface water and municipal drinking water supplies. More than 1200 laboratory analyses were performed on these environmental samples. The results showed that radioactivity levels were not significantly increased from the radioactivity levels detected prior to the operation of the plant.
Direct radiation measurements were taken at 67 locations using thermoluminescent dosimeters. The average quarterly dose was 15.4 mrem / standard quarter and is consistent with ambient radiation levels measured prior to the operation of the plant.
Atmospheric monitoring results for 1993 were within the same range as measurements made prior to the operation of the plant. No radioactivity attributable to the operation of Fermi 2 was detected in any atmospheric samples during 1993.
Terrestrial monitoring ofleafy garden vegetables and milk, showed naturally occurring radioactivity and radioactivity associated with past weapons testing and the nuclear accident at Chernobyl (U.S.S.R.). The radioactivity levels detected were consistent with the preoperational and, with the exception of 1986, the year of the accident at Chernobyl, prior operational levels.
Aquatic monitoring includes analysis of fish samples, shoreline sediment samples, and lake bottom       l sediment samples. All sample media from the Fermi 2 REMP program showed radioactivity levels that       l were consistent with levels detected prior to the operation of the plant.                               l Drinking water, surface water, and groundwater monitoring results were consistent with the results obtained prior to the operation of the plant. None of the 1993 water samples showed detectable radioactivity due to the operation of Fermi 2.
The maximum dose to a member of the general public due to radioactivity released as gaseous effluents was less than 1.0% of the annual limit.
The maximum dose to a member of the general public due to radioactivity released as liquid effluents was less than 0.1% of the annual limit.

I Comparisons of 1993 environmental data, pre-1993 data, and preoperatianal data showed that the operation of Fermi 2 had no significant radiological impact upon the environment.
In October of 1991, sediment samples were collected in the cooling water discharge canal as part of the Fermi 1 Environmental Monitoring Program. These samples showed low concentrations of Manganese-54 (M n-54), Cobalt-60 (Co-60), Zinc-65 (Zn-65), and Cesium- 137 (Cs-137). Given that Mn-54 and Zn-65 have short half-lives (approximately 250 days), and that the last discharge from            l Fermi 1 was made in June 1975, it is unlikely that these radioisotopes in these samples resulted from the operation of Fermi 1. Detroit Edison believes that the radioactivity in these sediments is the result of the recirculation of Fermi 2 liquid effluent releases. Since 1901 Detroit Edison has conducted additional sampling and monitoring to evaluate the recirculation ofliquid releases. The information on this additional sampling and monitoring is provided in Appendix "C".
In December 1993 a malfunction of the turbine / generator at Fermi 2 Nuclear Power Plant occurred.
At no time during the event did a radiological safety problem exist. No increases in plant radiation levels or in radioactive emuent levels above those typical for the operation and shutdown of the plant were encountered. As a confirmation that no significant releases occurred Detroit Edison has been conducting additional environmental monitoring around the plant. The information regarding this additional monitoring is provided in Appendix "D" 2..i Erecutiw Summary

Termi2 - l993 Annual RadiologicalEnvironmental Monitoring Reprt QlittlityAsstirririce An important part of the environmental monitoring program at Fermi 2 is Quality Assurance (QA),
which is conducted in accordance with NRC Regulatory Guide 4.15, " Quality Assurance for Radiological Monitoring Programs." As defined by Regulatory Guide 4.15, QA comprises " planned and systematic actions that are necessary to provide adequate confidence in the results of a monitoring prograrn.
Aspects ofQA for the Fermi 2 environmental monitoring program indude clearly defined organizational structure and responsibilities, qualification and training of personnel, approved written procedures, methods to ensure sampling adequacy, internal controls at the contract laboratory, and participation by the contract laboratory in an interlaboratory comparison program. The interlaboratory comparison program used by the contract laboratory (Teledyne Isotopes East)* is the EPA's Environmental Radioactivity Laboratory Intercomparison Studies program. Teledyne Isotopes East's 1993 performance in this program is detailed in Appendix A.

1 Fermi 2- 199J Annual RadiologicalEnvironmental Monitoring Report         j Program Summary The purpose of the Radiological Environmental hionitoring Program (REhiP) is to assess the environmental impact ofoperating Fermi 2. This program also provides the verification of the effluent monitoring program during routine operation of the plant and serves as an in place sampling network in the event of an accidental release. hionitoring stations are placed at pre-determined locations which measure any effects from operating the plant, and at control locations which are beyond the influence of the plant. At Fermi 2, the monitoring program is designed to measure radiation emosure to the public. Exposure to the public can occur through direct pathways such as inhalation or immersion, or indirectly through the food chain. These exposure pathways are monitored using thermoluminescent dosimeters (TLDs), and by the collection of air, milk, garden produce, water, fish, and sediment samples.
Direct exposure by inhalation or immersion is measured both by TLDs and by collection ofair samples.
TLDs continuously monitor the radiation environment and provide a direct measurement of ambient gamma radiation levels. The locatians of both the TLD and air sampling sites were chosen with respect to the meteorology and population distribution around Fermi 2.
Air samples are collected through a particulate filter and an activated charcoal filter in tandem using continuously running air samplers. The particulate filters are analyzed individually for gross beta activity and composited for gamma spectrum analysis. The charcoal fihers are analyzed for iodine-131 (1-131).
Radionuclides can enter the food chain through atmospheric or liquid discharges from the plant.
Radionuclides released to the atmosphere, such as I-131, may be deposited on agricultural land and then ingested by dairy cows or goats, becoming concentrated in the animals' milk. Radionuclides can also become incorporated in garden produce such as green leafy vegetables. hionitoring for radionuclides due to liquid discharges includes collection of s,urface and drinking water, fish and sediment samples.
These samples are collected upstream (north) of the plant discharge at control locations, at the discharge and downstream (south) of the discharge at indicator locations.

l Fish are sampled semiannually and the species collected correspond to those that may be consumed by the local population. Fish are good indicators because they tend to bioaccumulate radionuclides that they have ingested and provide an effective mechanism for integrating the variable small concentrations of radionuclides in the water over extended periods. Sediments are also collected semiannually.
Sediment, in the vicinity of the liquid radwaste discharge, represents the most likely site for accumulation of radionuclides in the aquatic environment and, with long-lived radionuclides, a gradual increase in radioactivity concentration is expected over time. Sediments, therefore, provide a long-term indication of change that may appear in other sample media (i.e., water and fish samples).
Preoperationalprogram All nuclear power plants are required by the Nuclear Regulatory Commission (NRC) to conduct radiological environmental monitoring before construction of a facility. This preoperational program at Fermi 2 was aimed at collecting data needed to identify critical pathways, and determine the existing levels of radiation and radioactive products occurring naturally and from man-made sources in the vicinity of the plant. Fermi 2 began its preoperational program seven years (1978) before the plant achieved initial criticality in June 1985. The data accumulated during those years established a baseline to which operational data can be compared. The program consisted of monitoring air, drinking water, surface water, lake sediments, milk, vegetables, fish, and direct radiation in the environment in the vicinity of Fermi 2. The elements that made up the preoperational monitoring program are still in effect today.
1 Operationalprogram l
The preoperational program became the operational program in June of 1985 when initial criticality           i was achieved for the Fermi 2 reactor. The sampling and analysis program in the operational phase continuously monitors direct radiation, radioactivity in air, lake sediments and water, drinking water, groundwater, cow and goat milk, and local garden vegetables.
Table 4-1 Operational Sampling and Analysis is the number ofsamples collected and analyzed for the year of 1993.

Fermi 2- 1993 Annual RadiologicalEnvironmental Monitoring Report Nuclear Regulatory Commission Monitoring Program The U.S. Nuclear Regulatory Commission (NRC) Direct Radiation Monitoring Network is operated in cooperation with the State of Michigan's Division of Radiological Health. This program provides continuous measurement of ambient levels of radiation around the Fermi 2 site. Ambient radiation levels result from naturally occurring radionuclides present in the soil, fallout from past atmospheric nuclear weapons testing, cosmic radiation from outer space and the contribution, if any, from the monitored nuclear plant. This network both establishes background radiation levels from mutine facility operations and also determines the radiological impact of any abnormal facility operations.
         ' The NRC maintaint 41 thermoluminescent dosimeter (TLD) locations around Fermi 2, and 21 are co-located with Detroit Edison TLDs. Their locations are listed in Table 10-1. The TLDs are collected by State ofMichigan representatives and are analyzed independently of the Fermi 2 TLDs. The results of this ndependent assessment of the ambient radiation levels around Fermi 2 are consistent with the Fermi 2 TLD monitoring program measurements.
I i          The results from the NRC monitoring program are published quarterly in NUREG 0837 titled NRC TLD Dirut Radiation Monitoring Network.

Fenni2- 1993 Annual RadiologicalEnvironmental Afonitoring Report TerrestrialMonitoringProgram Introduction The terrestrial monitoring portion of the REMP provides for a continuous surveillance of the land-based environment surrounding Fermi 2. The program consists of monitoring the atmosphere, milk, and v% nbles for radioactivity that might originate from the operation of the plant. The program also monitors cirect radiation in the environment surrounding Fermi 2. The following sections discuss the type and frequency of terrestrial sampling, analyses performed, and a comparison of 1993 data to previous operational and preoperational data.
Direct radiation Detroit Edison uses thermoluminescent dosimeters (TLDs) to measure direct gamma radiation in the environment around Fermi 2. Teledyne Isotopes East environmental TLDs are presently being used to measure direct radiation. These dosimeters are 25% by weight calcium sulfate encased in teflon. 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. While in the field, these TLDs are exposed to background radiation and, ifmeasurable, gaseous efiluents and direct radiation from Fermi l
: 2. Environmental TLDs are exchanged and processed on a quarterly basis. Ind:cator TLDs are located         I within a ten mile radius of the plant and control TLDs are located greater tuan ten miles.                 l The average exposure for indicator TLDs during the preoperational program was 17.3 mrem /Std Qtr and 17.6 mrem /Std Qtr for control TLDs. The annual average exposure for indicator TLDs ranged from 13.6 to 21.0 mrem /Std Qtr. The annual average exposure for control TLDs ranged from 15.5 to 21.9 mrem /Std Qtr.
From 1985 to 1992 the average exposure for indicator TLDs was 15.9 mrem /Std Qtr and 16.4 mrem /
Std Qtr for control TLDs. The annual average exposure for indicator TLDs ranged from 13.6 to 20.3 mrem /Std Qtr. The annual average exposure means for control TLDs ranged from 13.4 to 22.2 mrem /
Std Qtr. As Figure 6-1 shows, the operational period fmm 1985 to 1992 was consistent with the preoperational program.

TLDs had an average exposure of 15.2 mrem /Std Q.tr and ranged from 13.1 to 20.0 mrem /Std Qtr.                                                                )
As Figure 6-1 shows, the average exposure for indicator and control TLDs was consistent with previous years, including preoperational years.

Fermi 2- 1993 Annual R,idiologicalEnvironmental Monitoring Report Air Sampling Detroit Edison continuously samples the atmosphere 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 and Iodine-131 activities. The particulate filters for each sampling location are combined on a quarterly basis to form a " composite sample" and are analyzed for Strontium-89/90 and gamma emitting isotopes.
There are four indicator sampling locations which were selected based on an evaluation of the predominant wind directions. A fifth sampling location is approximately 14 miles west of the plant and is considered to be a control location unaffected by the operation of the plant.
During the preoperational program, excluding the year 1981, the average gross beta for indicator air samples was 2.6E-2 pCi/ cubic meter and ranged from 2.0E-2 to 4.0E-2 pCi/ cubic meter. The average gross beta for the control samples was 2.5 E-2 pCi/ cubic meter and ranged from 1.9E-2 to 3.5E-2 pCi/
cubic meter.
In late 1980, the Peoples Republic ofChina conducted an atmospheric nuclear weapon test. The fallout from this test was detected in Fermi 2 environmental air samples in 1981. The average gross beta for 1981 was 1.6E-1 pCi/ cubic meter for indicator samples and 2.4E-1 pCi/ cubic meter for control samples. Gamma spectroscopic analyses of the particulate filters revealed Cesium-137 (Cs-137),
Cerium-141 (Ce-141), Cerium-144 (Ce-144), Ruthenium-103 (Ru-103), Ruthenium-106 (Ru-106), Zirconium-95 (Zr-95), Niobium-95 (Nb-95), Manganese-54 (Mn-54), and Antimony-125 (Sb-125) in the atmosphere as a result of this test.

1 From 1985 to 1992 the average gross beta for indicator samples was 2.2E-2 pCi/ cubic meter and ranged                                        j from 2.0E-2 to 3.4 E-2 pCi/ cubic meter. The average gross beta for the control samples was 2.2E-2 pCi/                                     l cubic meter and ranged from 2.0E-2 to 3.3E-2 pCi/ cubic meter. In 1986, as shown in Figure 6-2, there                                       !
was a slight increase in gross beta activity and a 2.7E-1 pCi/ cubic meter " spike" in the Iodine 131 activity. These elevated activity levels have been attributed to the nuclear accident at Chernobyl (U.S.S.R.) on April 26,1986. For the operational period from 1985 to 1992, excluding 1986, the air sampling data is consistent with the preoperational data.

beta activity and two hundred and sixty (260) charcoal filters were collected and analyzed for 1-131.
The average gross beta for indicator samples was 2.2E-2 pCi/ cubic meter and ranged from 1.0E-2 to 4.3E-2 pCi/ cubic meter. The average gross beta for control samples was also 2.2E-2 pCi/ cubic meter l                                        and ranged from 1.2E-2 to 3.9E-2 pCi/ cubic meter. The monthly average gross beta is shown in figure
:                                         6-3. The extremely small variations in the monthly gross beta averages are attributable to atmospheric l                                        factors such as wind patterns, precipitation, dust loading, pollen count, etc. None of the charcoal fdters

l RadiologicalEnvironmental Monitoring Report Milk sampling The milk sampling portion of the REMP is perhaps the most important aspect of the program. This is because a major radiation exposure pathway to the public can be the consumption of milk from local grazing animals (dairy cows or goats). Milk is collected from one indicator location and one control
!        location semi-monthly when animals are on pasture and monthly at other times. The milk is analyzed for I-131, gamma emitting isotopes, and Sr-89/90. Milk sampling began in 1979 in the preoperational program. During this time period milk samples were only analyzed for 1-131 and gamma emitting l        isotopes. From 1979 to 1984 Cs-137 from past nuclear weapons testing and naturally occurring K-40 were the only isotopes detected in milk samples. During the operational period between 1985 and 1987, milk samples were also only analyzed for I-131 and gamma emitting isotopes. In 1986, after the nuclear accident at Chernobyl (U.S.S.R.) I-131 and Cs-137 were detected in both indicator and control milk samples. The analysis for Sr-89/90 began in 1988 and Sr-90 is now routinely detected in both indicator and control milk samples. The presence of Sr-90 in .nilk and other environmental l        samples is due to past atmospheric nuclear weapons testing. Naturally occurring K-40 was also detected in milk samples during this period. For the operational period from 1985 to 1992, excluding 1986, the milk sample data is consistent with the preoperational data.
During 1993, thirty six (36) milk samples were collected and analped for 1-131, gamma emitting             l isotopes, and Sr-89/90. Naturally occurring K-40 was detected in both indicator and control samples.
Sr-90 was also detected in both indicator and control milk samples. The indicator samples had an average Sr-90 concentration of 2.3E+0 pCilliter and ranged from 9.1E-1 to 3.7E+0 pCilliter. The control samples had an average Sr-90 concentration of 1.6E+0 pCi/ liter and ranged from 7.3E-1 to 3.6E+0 pCilliter. For 1993, the milk sampling data is consistent with prior operational data and preoperational data.

Figure 6-4 shows the calculated decay curve for the 1970 concentration of Sr-90 and the average concentrations since 1988. Figure 6-4 shows the inventory of Sr-90 at indicator levels in the local environment is decreasing with time and closely follows the calculated decay curve. This would associate the inventory of Sr-90 in the environment to past atmospheric nuclear weapons testing.

Fermi 2 collects samples ofleafy 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 I
growing season (June through September) and are analyzed for 1-131 and gamma emitting isotopes.
Vegetable sampling started in 1982. During the preoperat:onal program, only naturally oc:urring K-40 was detected in both indicator and control vegetable samples. During the operational period from 1985 to 1990, only naturally occurring K-40 was detected in both indicator and control vegetable samples. In 1991 and 1992 Cs-137 was detected in one indicator sample each year and had a Cs-137 average concentration of 1.2E+ 1 pCilkg wet weight. The presence of Cs-137 in vegetable s.:mples can l       be attributed to past atmospheric weapons testing and possibly to the nuclear accident at Chernobyl (U.S.S.R).
During 1993, twenty four (24) vegetable samples were collected and analyzed for I-131 and gamma emitting isotopes. Naturally occurring K-40, Be-7 and Thorium-228 (Th-228) were detected in both indicator and control vegetable samples. One indicator sample showed activity for Cs-137 with a concentration of 1.lE+1 pCi/kg wet weight. The presence of Cs-137 in vegetable samples can be attributed to past atmospheric nuclear weapons testing and possibly to the nuclear accident at Chernobyl (U.S.S.R.). Since Cs-137 has never been detected in any gaseous effluent sample from Fermi 2, and since the pathway from Fermi 2 to vegetables would be the depesition ofgaseous emuents on the ground, this implies that none of the Cs-137 activity in vegetables is due to Fermi 2 effluents.
For 1993, the vegetable sample data is consistent with prior operational data and preoperational data.

Fmni2- 1993 Annual Radiological Environmental Afonitoring Rej> ort AquaticMonitoringProgram introduction The aquatic monitoring portion of the REMP provides a continuous surveillance of Lake Erie, on which the plant site borders. The program consists of monitoring raw municipal drinking water, surface water, groundwater, lake sediments, and fish for radioactivity due to the operation of the plant.
The following sections discuss the type and frequency of aquatic sampling, analyses performed, and a comparison of 1993 data to previous operational and preoperational data.
Drinking water sampling Detroit Edison continuously monitors drinking water at one control location and two indicator locations using automatic compositing samplers. In this program composite sample aliquots are collected at time intervals that are very short (hourly) relative to the compositing period (monthly) in order to assure obtaining a representative sample. Indicator water samples are obtained at the Monroe water intake located approximately 1.1 miles south of the plant and at the Fermi 1 potable water plant located approximately 0.3 mile south southeast 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 isotopes. The monthly samples for each location are combined on a quarterly basis to form a quarterly composite sample and are analyzed for tritium.
Drinking water sampling began in 1979 and the samples were only analyzed for gross beta, gamma emitting isotopes, and tritium. The average annual gross beta for indicator drinking water samples, excluding 1981, during the preoperanonal program was 3.4E+0 pCi/ liter and ranged from 2.1 E+0 to
;        4.3E+0 pCi/ liter. The average annual gross beta for control drinking water samples during this time l
period was 3.5E+0 pCi/ liter and ranged from 2.9E+0 to 4.5E+0 pCi/ liter. In 1980 and 1983 Cs-137 was detected at levels ranging from 5.4E+0 to 1.9E+1 pCi/ liter. Tritium was also detected during the preoperational program and had an annual average of 3.2E+2 pCi/ liter and ranged from 2.6E+2 to 4.5E+2 pCi/ liter.

Fermi 2- 1993 Annual RadiologicalEnvironmental Monitoring Report From 1985 to 1992, the average annual gross beta activity for indicator drinking water samples was 2.9E+0 pCi/ liter and ranged from 2.4E+0 to 3.9E+0 pCilliter. The average annual gross beta for control drinking water samples was 2.5E+0 pCilliter and ranged from 1.9E+0 to 3.3E+0 pCilliter. The analysis for Sr-89/90 began in 1988 and St-90 has been detected in botn indicator and control samples.
The average annual Sr-90 activity for indicator samples was 7.3E 1 pCi/ liter and ranged from 4.8E-I to 1.2E+0 pCilliter. The average annual Sr-90 activity for control samples was 7.6E-1 pCilliter and ranged from 7.lE-1 to 8.0E-1 pCi/ liter. Tritium was also detected in both indicator and control drinking water samples during this time period. The average annual tritium activity for indicator samples for years that tritium was detected was 2.8E+2 pCi/ liter and ranged from 2.2E+2 to 3.9E+2 pCi/ liter. The average annual tritium activity for control samples for years that tritium was detected l
was 3.0E+2 pCi/ liter and ranged from 2.7E+2 to 3.4E+2 pCi/ liter. For the operational period from 1985 to 1992, the drinking water sample data is consistent with the preoperational data.
l In 1993, thirty nine (39) drinking water samples were collected and analped for gross beta, gamma emitting isotopes, St-89/90, and tritium. The average annual gross beta for indicator samples was i  3.7E40 and ranged from 2.3E+0 to 6.9E+0 pCi/ liter. The average annual gross beta for control samples was 3.2E+0 pCilliter and ranged from 1.6E+0 to 7.3E+0 pCi/ liter. No gamma emitting isotopes or Sr-89/90 activity were detected in drinking water samples during 1993. Twelve (12) quarterly l
composite drinking water samples were prepared and analyzed for tritium. No tritium activity was detected in drinking water samples for 1993. For 1993, the drinking water sample data is consistent I  with prior operational data and preoperational data.

l Detroit Edison continuously monitors surface water at two locations using automatic composite samplers. As with drinking water, surface water aliquots are collected at time intervals that are very short (hourly) relative to the compositing period (monthly) in order to assure obtaining a representative sample. Indicator surface water samples are obtained at the Fermi 2 General Service Water building.          l This location is approximately 0.3 mile 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 north east of Fermi 2. Surface water samples are collected on a monthly basis and analyzed for Strontium 89/90 and gamma emitting isotopes. The monthly samples for each location are combined on a quarterly basis to form a quarterly composite sample and are analyzed for tritium.
Surface water sampling began in 1979 and the samples were only analyzed for gamma emitting isotopes, and tritium. During this preoperational program no gamma emitting isotopes, except for naturally occurring K-40, were detected. Tritium was detected in both indicator and control samples during this time period and had an annual average of 3.2E+2 pCi/ liter and ranged from 2.2E+2 to 4.lE+2 pCilliter.
From 1985 to 1989, no gamma emitting isotopes were detected in surface water samples, although Sr-90 was detected in both indicator and control samples. The average annual St-90 activity for indicator samples was 1.6E+0 pCilliter and ranged from 8.3E-1 to 2.4E+0 pCi/ liter. Only one control sample had St-90 activity (7.6E-1 pCilliter). Tritium also was detected in both indicator and control samples for this time period. The average annual tritium activity for indicator samples was 2.3 E+ 2 pCi/ liter and ranged from 1.6E+2 to 3.lE+2 pCilliter. Only one control sample had tritium activity (2.4E+2 pCi/
liter). In 1990, two indicator samples showed detectable activity for Cs-137 at an average concentration    j of 1.2E+ 1 pCi/ liter and ranged from 9.7E+0 to 1.5E+ 1 pCilliter. In 1991, St-90 was detected in one       i indicator sample at a concentration of 5.3E-1 pCi/ liter. The presence of St-90 in surface water samples is due to past atmospheric nuclear weapons testing. In 1992 no gamma emitting isotopes, Sr-89/90, or tritium were detected in surface water samples.
In 1993 twenty six (26) surface water samples were collected and analyzed for gamma emitting isotopes I
and Sr-89/90. No gamma emitting isotopes or Sr-89/90 were detected in surface water samples. Eight (8) quarterly composite surface water samples were prepared and analyzed for tritium. No tritium activity was detected in surface water samples for 1993. For 1993, the surface water sampling data is consistent with prior operational data and preoperational data.

Fermi 2- 1993 Annual RadiologicalEnvironmental Afonitoring Report Groundwater sampling Groundwater is collected on a quartedy basis from four wells surrounding Fermi 2. The groundwater is analyzed for gamma emitting isotopes and tritium. The subsurface hydmlog of the local area is such that groundwater flows towards Lake Erie. For this reason, sampling location GW-4 which is located approximately 0.6 mile west northwest is least likely to be affected by the operation of the plant, and as such is considered a control location.
Groundwater sampling began in 1987. From 1987 to 1989 no radioactivity was detected in groundwater samples. In 1990, Cs-137 and tritium were detected in groundwater samples. Cs-137 was detected in one control sample at an activity concentration of 7.7E+0 pCilliter and is most likely due to past nuclear weapons testing. Tritium was detected in one indicator sample and one control sample.
The indicator sample had a tritium activity of 9.9 E+ 1 pCilliter and the control sample had a tritium activity of 8.9 E+1 pCilliter. The tritium activity detected in these samples is most likely due to past nuclear weapons testing and from naturally occurring tritium. From 1991 to 1992 only naturally occurring K-40 was detected in groundwater samples.
In 1993, sixteen (16) groundwater samples were collected and analyzed for gamma emitting isotopes and tritium. No gamma emitting isotopes or tritium were detected in gmundwater samples. For 1993, the groundwater sample data is consistent with prior operational data and preoperational data.
Sediment sampling Lake Erie shoreline and bottom sediments fmm five locations are collected on a semiannual basis and are analyzed for gamma emitting isotopes 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, near the Fermi liquid discharge area, the shoreline at the end of Pointe Aux Peaux, and Indian Trails Community Beach.
l       During the preoperational program there was not a control location and samples were only analyzed l       for gamma emitting isotopes. During the preoperational program, except for naturally occurring isotopes, only Cs-137 was detected in sediment samples. For this tirne period the average Cs-137 concentration was 3.3E+2 pCi/kg and ranged from 5.0E+1 to 6.6E+2 pCi/kg.

analysis for Sr-89/90 began in 1988 and St-90 has been detected in both indicator and control samples.                     l The average annual Sr-90 activity for indicator samples was 9.6E+ 1 pCi/kg and ranged from 2.8E+ 1 to 1.6E+2 pCi/kg. The average annual Sr-90 activity for control samples was 2.5E+2 pCi/kg and ranged from 1.4E+2 to 3.lE+2 pCi/kg. In 1990 and 1991, the Spring sample taken at the Fermi 2 discharge line (Location S-2) showed activity for plant related isotopes (Mn-54, Co-58, Co-60, and Zn-65) and was a result ofliquid efTluent from Fermi 2.
Figure 7-2 shows the concentration ofCs-137 in sediment samples from 1978 to 1993. Using the data from these years and the statistical method of a computer generated Best Fit Trend Line, an overall                        l trend of Cs-137 in environmental sediment samples can be calculated. This trend line shows a negative slope which indicates the overall concentration of Cs-137 is decreasing with time. This would verify that the inventory of Cs-137 in lake sediments is due to past atmospheric nuclear weapons testing and not from the operation of Fermi 2.

I In 1993, ten (10) sediment samples were collected and analyzed for gamma emitting isotopes and Strontium 89/90. No Sr-89/90 was detected in any sediment samples. Naturally occurring gamma l
emitting isotopes were detected in both indicator and control sediment samples. Cs-137 was l
!        detected in one indicator and both control sediment samples. The indicator sample showed a              l l        Cs-137 concentration of 5.lE+1 pCi/kg. The control samples showed a Cs-137 concentration of 1.8E+2 pCi/kg and ranged from 7.5E+1 to 2.8E+2 pCi/kg. The presence of Cs-137 in sediment samples appear to be due to past atmospheric nuclear weapons testing, and not the operation of Fermi 2.
For 1993, the sediment sample data is consistent with prior operational data and preoperational data.
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 Brest Bay. The indicator location is approximately 1200 feet offshore of the Fermi 2 liquid discharge. Edible portions of the fish are analyzed for gamma emitting isotopes and Strontium 89/90.
During the preoperational program only naturally occurring isotopes and Cs-137 were detected. The average Cs-137 concentration for indicator samples was 3.5E+ 1 pCi/kg and 4.2E+ 1 pCi/kg for control samples. Preoperational fish samples were only analyzed for gamma emitting isotopes.
From 1985 to 1992, the average Cs-137 concentration for indicator samples was 5.2E+ 1 pCi/kg and ranged from 2.0E+1 to 7.2E+1 pCi/kg. The average Cs-137 concentration for control samples was 5.5E+1 pCi/kg and ranged from 2.5E+1 to 9.7E+1 pCi/kg. The analysis for Sr-89/90 began in 1990 and St-90 has been detected in both indicator and control samples. Since then the average Sr-90 concentration for indicator samples was 6.8E+1 pCi/kg and ranged from 2.7E+1 to 1.3E+2 pCi/kg.
The average St-90 concentration for control samples was 5.6E+1pCilkg and ranged from 2.7E+1 to 7.7E+1 pCilkg.
In 1993, thirteen (13) fish samples were collected and analyzed for gamma emitting isotopes and Strontium 89/90. Naturally occurring gamma emitting isotopes were detected in both indicator and control fish samples. Cs-137 was detected in one control fish sample and had a Cs-137 concentration of 3.0E+1 pCi/kg. Sr-90 was detected in both indicator and control fish samples. The average concentration of Sr-90 for indicator samples was 2.0E+1 pCilkg and ranged from 1.1E+1 to 4.lE+1 pCi/kg. The average concentration of Sr-90 for control samples was 1.2E+ 1 pCi/kg and ranged from 1.lE+1 to 1.3E+1 pCi/kg.
For 1993, the fish sample data is consistent with prior operational data and preoperational data.

An annual Land Use Census is conducted by Detroit Edison to update informatlon used to estimate the radiation dose to the public and to determine ifany modifications to the Radiokgical Environmen-tal Monitoring Program are necessary. This information ensures that these programs are as accurate as possible. The Land Use Census is required by Title 10 of the Code of Federal Regulations, Part 50, Appendix I and the Fermi 2 Offsite Dose Calculation Manual (ODCM) Section 3/4.12.2.
The Land Use Census is conducted at a maximum distance of 5 miles from Fermi 2, and identifies the locations of the nearest milk producing animals, the nearest residence, and the nearest garden (greater than 50 square meters and containing broad leaf vegetation) in each of the 16 meteorological sectors.
Cardens greater than 50 square meters are the minimum size required to produce the quantity (26 kg/
year) ofleafy vegetables assumed in Regulatory Guide 1.109 for the 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.
1993 Land Use Census results The I and Use Census was conducted during the month of August in 1993. The census data was obtained by driving all roads within a five mile radius and in some cases performing door-to-door surveys. The data was then compared with the 1992 data to determine any changes in the local area.
The analysis of the new Land Use Census data showed no change to the critical receptor for calculation of olisite dose due to gaseous effiuents. The critical receptor is defined as the individual living ofTsite who could receive the maximum dose due to 1-131, I-133, H-3 and products with half-lives greater than eight days in gaseous effluents. Only minor changes were found in the 1993 data when compared to the 1992 data and were determined to be insignificant. The information gathered during the 1993 Land Use Census is tabulated and presented in Tables 8-1 through 8-3.

Fermi 2- l993 Annual RadiologicalEnvironmental Monisoring Report Program Execution In 1993, the major deviations from scheduled REMP activities were the loss ofTLDs due to vandalism, air sampler loss ofelectrical power, and drinking water and surface water equipment malfunctions. The following lists all deviations and corrective actions from the normal sampling schedule for 1993. These desiations did not have a significant impact on the execution of the REMP.
Environmental TLDs All TLDs are placed in the field in inconspicuous locations to minimize the loss of TLDs due to vandalism. During 1993, two hundred fifty six (256) TLDs were placed in the field, and three (3) were found missing. This represents a 98.8 percent successful collection rate.
The following are deviations from the normal sampling schedule:
On 04/01/93, during the quarterly TLD exchange the following TLD was found missing and was replaced during the TLD change out: T-34.
On 10/01/93, added new TLD locations T-64,T-65,T-66, and T-67 to the REMP TLD network.
On 10/01/93, during the quarterly TLD exchange the following TLD was found missing and was replaced during the TLD change out: T-12.
On 11/19/93, during the mid-quarter TLD inspection, the following TLD was found missing and replaced with a spare: T-56.                                                                               i l

Airsampling During 1993, five hundred twenty (520) air samples were scheduled to be collected. Four (4) of the five hundred nventy (520) air samples collected were considered to be less than representative of the sample period due to equipment failure.

Fermi 2 - l993 Annual RadiologicalEnvironmental Monitoring Report The following are deviations from the normal sampling schedule:
On 02/02/93 all air samplers ran six (6) days due to an adjustment in the sampling schedule.
On 06/22/93, during filter exchange API-5 was found not operating due to a loss ofpower to the utility pole where the air sampler is located. Power was restored to the utility pole on 06/23/93. This sample was considered less than representative for the sampling period.
On 06/29/93, API-5 sampler only ran six days due to problems incurred from 06/22/93. Sampler was put back on normal schedule the same day.
On 12/14/93, during fdter exchange APl-1 was found not operating due to a loss ofpower to the utility pole where the air sampler is located. Power was restored to the utility pole the same day. This sample was considered less than representative for this sampling period.
Milk sampling During 1993, thirty six (36) milk samples were collected. This represents a 100 percent successful collection rate for the year.
Drinking water sampling During 1993, of the thirry nine (39) drinking water samples collected, three (3) were partial samples and considered less than fully representative. This represents a 92.3 percent successful collection rate for the year.
The following are deviations from the normal sampling schedule:
On 04/06/93, a grab sample was taken at location DW-2 due to a loss ofpower. Power was interrupted at the plant by municipal plant personnel to run new power lines and switch electrical busses during water plant annual testing. The sampler was reset and returned to normal operation the same day.
On 04/27/93, the composite drinking water sample collected at location DW-2 for the month ofApril was considered to be less than fully representative due to the power interruption to the sampler, the week of 04/06/93.
9-4 Program Execution

Emni 2- 1993 Annual Radiological Entironmental Monitoring Report On 05/03/93, a grab sample was taken at location DW-2. Pressure regulator failed due to water plant personnel altering the flowpath of piping in order to allow for testing of micro-organisms in the raw water system. Pressure regulator was reset and sampler was put back into operation the same day.
On 05/25/93, the composite drinking water sample collected at location DW-2 for the month of May was considered to be less than fully representative due to the problems that occurred the week of 05/03/93.
On 07/20/93, a grab sample was taken at location DW-3 due to a valve to the sampler being closed off during the previous day's shutdown of the potable water plant. The valve was tagged the same day to inform plant personnel to leave valve open at all times.
On 07/27/93, the composite drinking water sample collected at location DW-3 for the month ofJuly was considered to be less than representative due to the problem with the valve the week of 07/20/93.
Surface water sampling During 1993, of the twenty six (26) surface water samples collected, two (2) were partial samples and considered less than fully representative. This represents a 92.3 percent successful collection rate for the year.
On 01/11/93, a grab sample was taken at location SW-2 due to ice build-up in the sample line. Ice was removed from sample line and sampler was put back into normal operation the same day.
On 01/27/93, the composite surface water sample collected at location SW-2 for the month ofJanuary was considered to be ! css than fully representative due to the ice build up problem that occurred the week of 01/11/93.
On 07/20/93, a grab sample was taken at location SW-2 due to a low weekly flow check. The flow to the sampler was reset to the normal setting and :eturned to normal operation the same day.
On 07/27/93, the surface water sample collected at location SW-2 for the month ofJuly was considered to be less than fully representative due to the flow problem that occurred the week of 07/20/93.

US EPA Interlaboratory Comparison Programfor 1993 l
l     Starting in 1991, Detroit Edison contracted Teledyne Isotopes East Laboratory (TI) to provide l     analyticai results of REM P environmental samples. Teledyne lsotopes participates in the Environ mental Protection Agency's (EPA) Interlaboratory Comparison program.
In the EPA Interlaboratory Comparison program, participant laboratories receive from the EPA environmental samples of known activity concentration for analysis. After the samples have been analyzed by the laboratory, the EPA reports the known activity concentration of the samples to the laboratory. The laboratory compares its results to the EPA reported concentrations to determine any l
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.
According to the EPA, the results from Teledyne Isotopes East Laboratory for 1993 are within the acceptable guidelines for a laboratory participating in the U.S. Environmental Protection Agency's Interlaboratory Comparison Program.

(a) EPA Results-Expectedlaboratory precision (1 sigma). Units are pCilliter for water and K is in mg/ liter. Units are total pCi for air particulate filters.
(b) Teledyne Results - Average +/- one sigma. Units are pCi/ liter for water and milk ex mg/ liter. Units are total pCi for air particulate filters.
(c) The EPA switched from Am-241 to Th-230 alpha spike. Teledyne Isotopes East c Th-230, using sodium nitrate to generate a self-absorption curve. The EPA water, ho minerals which have greater self-absorption than the sodium nitrate matrix. The EPA has ag send T1 a gallon of their water which Tl can use to prepare a self-absorption curve with (d) By oversight, TI did not use the special self-absorption curve which TI had previou EPA water and Cs-137 standard. Teledyne will use the EPA curve in the future. Teledyne m derive this curve using a water sample which the EPA has agreed to send Teledyne.
I (e) The calculations were checked and found to be correct. The results of six gamma emittin h 2 were reported to the EPA. The resuits of four were within i normalized deviation; a fifth, normalized deviations. Only the Zn-65 average was outside the control limits. Teledyne says no obvious reason why one isotope should be outside the controllimits, while five other isotopes we within control limits.
(f) An investigation is being conducted at the time of this report; the results will be availab Edison when the investigation is complete.

l'ermi 2 - 1993 Annual Radiologica! Entironmental Monitoring Report SpecialEnvironmentalSamples in October 1991, as part of the Fermi 1 Environmental hSnitoring Program, sediment samples were collected from the cooling water discharge canal formerly used by Fermi 1. Highly sensitive monitoring equipment indicated levels of radionuclides, close to the instrumentation lower limit of detection.
Although it is not uncommon to detect such low level activity near the discharges of nuclear power plants. As a precaution Detroit Edison began an investigation to determine the source.
The study, completed in 1992, ruled out the likelihood of any Fermi ) operations as the source of any of the radioactis e materials present in the sample. The materials detected were 481 pCi of Mn-54; 891 pCi of Co-60; and 270 pCi of Zn-65. Mn-54 and Zn-65 have short half-lives ofless than one year; the latest discharge from Fermi 1 was made in June 1975. (Using conservative numhers to estimate area and depth, the total activity was estimated to be 1.6 mci.)
After sampling over one hundred additionallocations and analyzing the results,it was determined that only three areas could be potential sources of the low level radioactivity in the cooling water channel.
These probable sources were in the General Service Water (GSW) intake and forebay area. By facility design, however, no radioactive systems are directly connected to the GSW intake. Therefore, analysts supected that the activity was part of the lake bottom material that was fdtered and collected by the traveling screens, where it was then transferred to the discharge pipe and released into the cooling water channel.
To confirm this theory, samples were taken from the nearby take bottom and shoreline. These samples revealed that the radionuclides had absorbed in the lake sediments. Due to wind-induced lake currents and the design of the GSW forebay, the materials were concentrated in and around the forebay. But            '
even at these concentrated low levels, the measurements were barely above those established by preoperational estimates (of naturally occurring radioactivity) during the licensing process of Fermi 2.
It is believed that the presence of the radioactivity in the sediments is a result of recirculation of plant liquid efHuents, which are well under federally established standards.

The study concluded that the levels o."udioactive material detected in the cooling water channel are of no concern to the general public. 'l his conclusion was based on very conservative assumptions in l
l   evaluating radiological concern: (1) the individual potentially affected lives on the land with the highest l   activity, even though the activity is confined to Detroit Edison property, and all food and drink l   consumed comes from the land with the highest activity; and (2) no credit is taken for the reduction l   of activity by radioactive decay over time. The radiation dose received by this individual would be less than 1 mrem in one year; over a fifty year period, the radiation dose would be less than 0.001 mrem per year. An additional 1 mrem per year is not even a measurable dosage, given the variation in background (i.e. naturally occurring) radiation.
1 Because the low levels of radioactivity in the samples studied are no different in their potential efTect on the public than preoperationallevels of radioactive materials, there is no basis for current or future l
l   radiological safety concern. Therefore, Detroit Edison will continue to monitor the identified locations and address fmal disposition of the material at the time of decommissioning (an option stipulated l   under Title 10 of the Code of Federal Regulations when no radiological concern is present).
During 1993 Detroit Edison continued to monitor the identified locations on a semiannual basis as part of the Radiological Environmental Monitoring Program.
Sediment samples were collected and analyzed at seven locations for gamma emitting isotopes.
Naturally occurring gamma emitting isotopes were detected in all samples. Cs-137 was detected in nine (9) of the fourteen (14) samples collected, had an average value of 2.9E+2 pCi/kg and ranged from 4.5E+ 1 to 4.1 E+2 pCilkg. The presence of Cs-137 has been detected in sediment samples in the past and is due to past atmospheric weapons testing. Co-60 was also detected in three (3) of the fourteen (14) samples collected, had an average value of 1.3E42 pCi/kg and ranged from 7.6E+ 1 to 2.1 E+ 2 pCi/
kg. Co-60 was detected in the same locations and at approximately the same levels during the initial investigation. Detroit Edison will continue to monitor and track these locations through the ongoing Radiological Environmental Monitoring Program.
The analyses performed on the special environmental samples are listed in this appendix as Supplemen-tal Sediments Analysis Table.

Fermi 2- l993 Annual RadiologicalEnvironmental Monitoring Rejsort Fmni2 lurbineIncident                                                                                          ,
I On December 25,1993, a malfunction of the turbine / generator at Fermi 2 Nuclear Power Plant occurred. The reactor was promptly shutdown and placed in a stable condition.                               l At no time during the event did a radiological safety problem exist. No increases in plant radiation levels or in radioactive effluent levels above those typical for the operation and shutdown of the plant were encountered. A Turbine building roof vent did open during the event, but it has been determined that the maximum amount of radioactive material released through the vent was only a small fraction of normal releases.
As a confirmation that no signi6 cant releases occurred, special and routine environmental monitoring was conducted. The TLDs, air particulate / air iodine, drinking water and surface water samples were collected and sent for analysis. Additionally because of the concern for a potential release to the Circulating Water Reservoir, water samples were collected. These samples were analyzed and showed no detectable activity of plant origin.
All environmental samples collected and analyzed since the event indicate that no significant release ofliquid or gaseous effluents containing radioisotopes resuhed from the event.
In the future, appropriate sampling will continue to be conducted to demonstrate that there was no measurable environmental effect from the event and that appropriate sampling, monitoring, and controls have been established to ensure that there are no significant environmental effects resulting from the plant's recovery.
