II. INTRODUCTION The Radiological Environmental Monitoring Program (REMP) at Clinton Power Station (CPS) is designed to monitor the environment surrounding the plant for any radioactive material that may be released by CPS as a result ofplant operations. The primary concern is what impact, if any, the radioactive materials released from CPS have on the generalpublic. This report isprepared in a way that is useful to a specialized scientific community. However, this introduction, the explanations in later sections, and minimal use of technical terms are all designed to make this report understandable and useful to those with no background in environmental monitoring. A. CHARACTERISTICS OF RADIATION Atoms whose nuclei contain an excess of energy are called radioactive atoms. They release this excess energy by expelling electromagnetic or particulate radiation from their atomic centers to become stable (non-radioactive). This process is called " radioactive decay". X-rays and gamma rays are examples of electromagnetic radiation and are similar in many ways to visible light, microwaves and radio-waves. Particulate radiation may be either electrically charged such as alpha and beta particles, or has no charge, like neutrons. The term " half-life" refers to the time required for half of a given amount of a radionuclide to decay. Some radionuclides have a half-life as short as a fraction of a second, while others have a half-life as long as a million years. Radionuclides may decay directly into stable elements or may undergo a series of decays which ultimately end up reaching a stable element. Radionuclides are found in nature (e.g., radioactive uranium, thorium, carbon and potassium), and may also be produced artificially in accelerators and nuclear reactors (e.g., radioactive iodine, cesium and cobalt). 3
NATURALLY OCCURRING MAN-MADE RADIONUCLIDES RADIONUCLIDES Uranium Iodine Thorium Cesium. Carbon Cobalt Potassium Strontium Lead Barium The activity of a radioactive source is the average number of nuclear disintegrations (decay) of the source per unit of time. The unit of activity is called the curie. A one curie radioactive source undergoes 2.2 trillion disintegrations per minute, but in the realm of nuclear power plant effluents and environmental radioactivity, this is a large unit. Therefore, two fractional units, the microcurio and the picocurie, are more commonly used. I curie (Ci) ' = 2,220,000,000,000 disintegrations / minute 1 millieurie (mci) = 2,220,000,000 disintegrations /minuto 1 microcurie (pCD = 2,220,000 disintegrations / minute 1 nanocurie (nCi) = 2,220 disintegrations /minuto 1 picoeurie (pCi) = 2.22 disintegrations / minute The microcurie (uci) is one millionth of a curie (Ci) and represents 2.2 million decays per minute. The picocurie (pci) is one millionth of a microcurie and represents 2.2 decays per minute. Another way of comparing the pCi and the Ci is by analogy with distances. A picocurie would be the width of a pencil mark while a curie would be 100 trips around the earth. Radioactivity is related to the half-life and the atomic mass of a radionuclide. For example, Uranium-235 (U-235) with a half-life of 704 million years requires about 462,400 grams to obtain an activity of one curie. But iodine-131 (I-131) with a half-life of 8.04 days only requires about 0.000008 grams to produca an activity of one curie. Any mechanism that can supply the energy necessary to ionize an atom, break a chemical bond, or alter the chemistry of a living cell are capable of producing biological damage. Electromagnetic and particulate radiation can produce cellular damage in any of these ways. In assessing the biological effects of radiation, 4
the type, energy, and amount of radiation must be considered. External total bcdy radiation involves exposure of all organs. Most background exposures are of this form. When radioactive elements enter the body through inhalation or ingestion, their distributio.n may not be uniform. TARGET TISSUE NUCLIDE Bone Strontium-90 Kidney Uranium-235 Thyroid Iodine-131 Muscle and Liver Tissue Cesium-137 Gastrointestinal Tract Cobalt-60 For example, radiciodine selectively concentrates in the thyroid gland, whereas radiocesium collects in muscle and liver tissue, and radiostrontium collects in mineralized bone. The total dose to organs by a given radionuclide is also influenced by the quantity and the duration of time that the radionuclide remains in the body. Owing to radioactive decay and human metabolism factors, some radionuclides stay in the body for very short times while others remain for years. The amount of radiation dose that an individual remives is expressed in rem. Since human exposure ',o radiation usually involves very small exposures, the millirem (mrem) is the unit most commonly used. One millirem is one thousandth of a rem. I millirem = 0.001 Rem B. SOURCES OFRADIATION EXPOSURE Many sources of radiation exposure exist. The most common and least controllable source is natural background radiation from cosmic rays and the earth which mankind has always lived with and always will. Every second of our lives, over seven thousand atoms undergo radioactive decay in the body of the average adult. 5

planet and everything that has come 'from the earth, , including our own bodies- -is, therefore, naturally radioactive.- i Natural Radionuclides In The Earth's Crust - :l t Potassium-40-(K-40).- .

These radionuclides aree introduced into the water, soil and air by such natural" processes as -volcanic . activity, weathering, erosion and radioactive _ decay- _; i Some -- of the 1 naturally occurring radionuclides, such as : ; radon, are a significant ' source of : radiation exposure to ; the general public. Radioactive radon is a - chemically- : inert gas' produced naturally in the ground :as a part .of the. uranium'and' thorium decay series. Radon: continues to j undergo. radioactive decay, producing new- . naturally radioactive 1 materials called . radon "
. daughters".. These ;
new materials, which are solid particles, noti gases, .can ' stick to surfaces such as dust particles inithe air. ; Concentrations of radon in air are variable' and- are ! affected by concentrations of uranium and thorium in ! soil, as well as, altitude, soil porosity, temperature, i l pressure, soil' moisture, rainfall,. snow cover, ; atmospheric conditions, and. season. Radon 'can move through cracks and openings into basements of buildings i and become trapped in a small air volume indoors. Thus, l indoor radon concentrations are usually higher than those found outdoors. Building materials such as cinder blocks and concrete are radon sources. _ Radon can also be dissolved in well water and contribilte to airborne radon
- in houses when released.through showers or; washing.
Dust containing . radon daughter particles can be inhaled and deposited on the surface of an individual's lung. Radon daughters emit high . energy alpha radiation . dose to . the lung lining. Table 1 -' shows the average annual
- effective dose due to radon.

- Beryllium-10, Carbon-14, tritium, and Sodium-22.
j Portions of these radionuclides become deposited on land - 4 or in water while the remainder stay suspended in the-atmosphere. l j consequently, there are natural radioactive materials in i the soil, water, air and building materials that contribute to radiation doses to the human body. Natural 4 drinking water contains trace amounts of uranium and i radium; milk contains measurable amounts of potassium-40. l Sources of natural radiation and their average -
- contributing radiation doses are summarized in Table 1.

~
general population of the United States. ~ Radiation 8 exposure levels from natural radiation fluctuate with ' l time and also can vary widely from location to location. I The average individual in the United States receives
- j approximately three hundred arem per year from natural -
{ sources. i ] In some areas of the country, the dose from natural
- radiation is significantly higher. Residents of -
l Colorado, five thousand feet above sea level, receive- ! additional dose due to the increase in cosmic and terrestrial radiation levels. In fact, for every one l! thousand feet in elevation above sea 1s.el, an individual i j will receive an additional one arem per year from cosmic 4 radiation. In several areas of the world, high j concentrations of mineral deposits result in _ natural
- background radiation levels of several thousand arem per j . year.
I In addition to natural background radiation, the average i individual is exposed to radiation from a number of man- ! made sources. The largest of these sources come from { - medical diagnosis: . X-rays, CAT-scans, fluoroscopic ,
- examinations and radio-pharmaceuticals. Approximately j 160 million people. in the United States are exposed to medical- or dental X-rays in any given year. The annual i dose to an individual from such irradiation averages 53 arem.

Smaller doses from man-made sources come from consumer products (e.g., television, smoke detectors, l fertilizers), fallout from prior nuclear weapons tests, j and production of nuclear power and its associated fuel cycle.
" Fallout" commonly refers to the radioactive debris that settles to the surface of the earth following the detonation of nuclear weapons. Fallout is dispersed throughout the environment but can be-washed down to the Earth's surface by rain or snow.
Radionuclides Found in Fallout ' Iodine-131 (I-131) Strontium-90 (Sr-90) Strontium-89 (Sr-89) Cesium-137 (Cs-137 There are approximately two hundred radionuclides produced in the nuclear weapon detonation process; a number of these are detected in fallout. The radionuclides found in fallout that produce most .of the
, fallout radiation exposures to man are iodine-131, l strontium-89, strontium-90, and. cesium-137.

s j } C. DESCRIPTION OF THE CLINTON POWER STATION j The Clinton Power Station is located in Harp Township, 1 DeWitt County, Illinois. It is approximately six miles east of Clinton, Illinois. The station, its V-shaped cooling lake, and the i surrounding Illinois Power Company-owned land encloses ! a 14,182 acres. This includes the 4,895-acre, man-made l 1 cooling lake and about 90 acres of. privately owned , i property. ' The plant is sited on approximately - 150 acres j , on the northern arm of the lake. The cooling water
- discharge flume, which discharges to the eastern arm of
- the lake, occupies an additional 130 acres. Although the
,' nuclear reactor, supporting equipment, and associated 3 electrical. generation and distribution equipment lie in i Harp Township, portions of the 14,182 acres lie in ] Wilson, Rutledge, DeWitt, Creek, Nixon and Santa - Anna ' ] Townships. 2
- The cooling lake was formed by constructing an earthen i dam near.the confluence of Salt Creek and the North Fork !
of. Salt' Creek. The resulting . lake has an average depth l 8 of 15.6 feet, and includes an ultimate heat sink of about l } 590 acre feet. The ultimate heat- sink provides I j sufficient water volume and cooling capacity for
- approximately thirty days of orlera. tion without -makeup
! water. l Through arrangements with the Illinois Department of Conservation, Clinton Lake and much of the area immediately adjacent to the lake are used for public j recreation activities, including swimming, boating, j water-skiing, hunting and fishing. Recreational i facilities exist at Clinton Lake and accommodate up to j 11,460 people per day during peak ' usage periods. The i outflow from Clinton Lake falls into Salt Creek and flows i . in a westerly direction for about 56 miles before joining ! the Sangamon River. The Sangamon River drains into the ! Illinois River . which enters the- Mississippi River near i Grafton, Illinois. The nearest use of . downstream water ! for drinking purposes is 242 river miles downstream of i ! Clinton Lake at Alton, Illinois, as verified from the t j~ Illinois Environmental Protection Agency Public Water 1 Service. Although sces farms in the Salt Creek drainage j area downstream of Clinton Lake use irrigation, the
- irrigation water.is drawn from wells, not from the waters j of Salt Creek.
l Approximately 810,000 individuals live within 50 miles of i the Clinton Power. Station. 'Over half are located in the
- major metropolitan centers of 'Bloomington-Normal (located about 23 miles north northwest),
~
Champaign-Urbana 4 (located about 31. miles east), Decatur (located about 22 i ( 12 e F
! . I i-l
' miles south southwest) and Springfield (located about 48 H l miles west southwest). The nearest city _is Clinton, the
- county seat of DeWitt County. The estimated. population of i
Clinton is about 8,000 people. Outside of. the urban areas, most. of the land within 50 - miles of the Clinton l Power Station is used for farming. The principal' crops grown are corn and soybeans. , i . i D. NUCLEAR REACTOR OPERATIONS ! The fuel of 'a nuclear reactor is made of thel element ! uranium in the form of uranium. oxide. The - fuel produces i power by the process called " fission". In fiss;.on, . the ,
- uranium atom absorbs a neutron and splits _ to produce fission products, heat, radiation and free neutrons. The -,
free neutrons travel in the reactor . core and further ; i absorption of neutrons by uranium permits the fission i
- process to continue. As the fission . process . continues, more fission products, radiation, heat and neutrons are produced and a sustained reaction occurs. _ The heat ;
produced is extracted from the fuel to produce steam that ; drives a turbine _ generator to produce electricity. ; l l , The fission products are predominantly radioactive. They ! l are unstable elements that emit radiation as they change ! i from unstable to stable elements. Neutrons that are not i absorbed by the uranium fuel may be absorbed by stable atoms in the materials that make up the components and i, structures of the reactor. In such cases, stable atoms ! often become radioactive. This process 'is called l " activation" and the radioactive atoms . which result are '
- called " activation products".

- water reactor (BWR). Figure 2 provides :a basic plant schematic for the Clinton Power Station and shows the I separation of the cooling water from plant systems. In j', this type of reactor the fuel -is formed into small ceramic pellets that are loaded into sealed ' fuel rods.

i I i The ' fuel rods are arranged in arrays called bundles that are supported within a massive steel reactor vessel. The spaces between the fuel rods are filled with water. The heat released during the fission of fuel atoms is transferred to the water surrounding the fuel rods. A type of pump that contains no moving parts.(a jet pump), and recirculation pumps are used to force the water to circulate through the fuel bundles to assure even cooling of the fuel rods. As the water absorbs heat from the fuel rods some of it is changed to steam. The steam is l used to drive a turbine which is coupled to a generator, thereby completing the conversion of -- the energy released ! during fission to electricity. l After the steam passes- through' the turbine it is ! condensed back to water and returned to the reactor ! vessel to repeat the process. As the water circulates through the' reactor pressure. vessel, corrosion allows s trace . quantities of the component and structure surfaces ' to get into the water. The corroded material also contains radioactive substances known as activated corrosion products. Radioactive fission and activation products are normally confined to the primary. system although small leaks from the primary system may occur. 1 E. CONTAINMENT OFRADIOACTIVITY During operating conditions, essentially all radioactivity is contained within the first of several - barriers that collectively prevent escape of i i radioactivity to the environment. l The fuel cladding (metal tubes) provides the first ! barrier. The ceramic fuel pellets are sealed within , zircaloy metal tubes. There is a small gap between the l fuel and the cladding where the noble gases and . volatile nuclides collect. The reactor pressure vessel and the steel piping of the primary coolant system provide the second barrier. The reactor - pressure vessel is a seventy-foot = high vessel with steel walls ranging from four to seven inches thick which encase the reactor . core. The reactor pressure vessel and the steel piping provide containment ~ for all radionuclides in the primary coolant. The containment Building.provides the third barrier. Tne Containment Building has steel-lined, four-foot-thick reinforced concrete walls which completely enclose the reactor pressure vessel and vital auxiliary equipment. l This structure provides a third line of defense against 17 j i

- absorb auch of .the; radiation emitted during reactor ;
j operation or from radioactive materials created during !
- reactor operations.
) 1 F. SOURCES OF RADIOACTIVE EFFLUENTS , l In an operating nuclear power plant, most of . the . fission ;
- products are retained within the fuel and fuel cladding. ,
i However,- the fuel . manufacturing process leaves traces of t l uranium on the exterior of the fuel tubes. Fission : 4 products from the eventual fission.of these traces may be ; Other small' amounts of 1 released to the primary coolant. ; 4 radioactive fission products are able to diffuse .or migrate through the fuel cladding and into the primary- [ coolant. ~ Trace quantities of the corrosion products from j component. and structural surfaces. that have been j activated, also get into the primary coolant.

RADIOACTIVE WASTE PROCESSING
. i In a normal operating nuclear power plant, radioactive !
liquid and gaseous wastes are collected, stored- and l
- processed through treatment systems to remove or reduce most of the- radioactivity (excluding tritium) prior to l reuse within the plant or discharge to the environment.
These processing systems are required by the Clinton l Power Station Offsite Dose Calculation Manual to be installed and operable to help ensure all releases of radioactive liquid and gaseous effluents are As Low As . Beasonably Achievable (ALARA). j 4 The liquid waste treatment systems consist of filters,
- demineralizers and evaporators. Liquid wastes are routed l 4
19
i 1 l through the waste. evaporators to .be degassed and
- distilled thereby reducing their volume and concentrating l; their radioactivity. The distillates are further treated through domineralizers and filters and transferred to the
- waste evaporator condensate storage tanks. Liquid wastes
- are processed' through the appropriate portions of the-L liquid waste treatment system to . provide assurance . that -
t the releases of radioactive materials in liquid offluents will be kept ALARA. I j . Liquid wastes are discharged into the plant cooling water ! i stream which varies from approximately ;5,000. gallons per j minute, when the plant is in shutdown, to 567,000 gallons
- per minute, when the plant is at full. power. The liquid
- effluents are thoroughly . mixed with and diluted by the
- plant cooling water as it travels the 3.4 miles of the . ,
l: discharge canal' before it enters Clinton Lake east of l i DeWitt County Road 14. ! The Clinton~ Power Station Offsite' Dose Calculation Manual !. requires that -liquid offluents not _contain a higher
- concentration of any. radioisotope than that which is set
- for continuous ' exposure to the general public.. This
- condition is satisfied at the point the liquid offluent i
is first introduced into the cooling water flow. The
- additional dilution that occurs in - the cooling water
- canal reduces 'the concentrations of' radioisotopes to
! between 1/73 (for minimum flow) and 1/1890 (for maximum { flow) of their original value before the water enters l Clinton Lake. l The concentrated radioactive solids captured in the { liquid waste treatment system r.re ' solidified and shipped
- off-site for- disposal at licensed low-level waste disposal facilities.
\ , l The gaseous effluents from the main condenser are held up ' i in the off-gas charcoal beds for at least 46 hours. This provides time for the decay of most of the radionuclides present since most have a: half-life of less than 8 hours, j.~ If gaseous effluents in the ventilation exhaust system
- for the containment Building and for the secondary i containment structure exceed conservatively set levels,
! they are processed through charcoal beds and ,high i efficiency particulate air filters in the Standby Gas i Treatment System before being discharged to the j environment. i i This combination of filters and charcoal beds is rated to be 95% efficient for removing lodines and greater than , 79% efficient for removing particulate material larger
- j. than one micron (one millionth of an inch) in diameter.

l RADIOLOGICAL ENV RONMENTAL MONITORING PROGRAM
P e i III. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM l A. PROGRAM DESCRIPTION The Clinton ' Power Station is required to. maintain a i radiological environmental monitoring program in l accordance with the Code of Federal' Regulations (CFR) Title 10, Section 20.1501 and . Criterion 64 of - CFR Title j .10, Part 50, Appendix A. The program.was developed using
- .the following guidance published by the United States ;
! Nuclear Regulatory Commission (USNRC)s l l
=> Regulatory Guide 4.1, " Programs for. Monitoring l Radioactivity in the Environs of Nuclear. Power Plants" l l '
=> USNRC Radiological Assessment Branch Technical :
j Position on. Radiological Environmental Monitoring j (1979) 1
- The Radiological Environmental Monitoring Program -is an I extensive program of sampling, measuring and analyzing d
that was instituted to monitor the radiological impact of 1 reactor operation on the . environment. . objectives of the program include: ! O ~ identification, measurement and evaluation of . existing radionuclides in the. environs -of the Clinton Power Station and fluctuations in radioactivity levels which may occur , O evaluation of the measurements to determine the impact l of Clinton Power Station operations on the local l radiation environment ! O collection of data needed to refine environmental 1 radiation transport models used in offsite dose l calculations
. O verification that radioactive material containment l j systems are functioning to minimize environmental !
j releases to levels that are ALARA 4 0 demonstration of compliance with regulations and : the ' l Clinton Power Station Offsite Dose Calculation Manual. < Implicit in these objectives are the requirements to trend and assess radiation exposure rates and ' radioactivity concentrations in the environment that may contribute to radiation exposure to the public. The program consists of two phases, preoperational (preop) and operational. L 21 _ _ _ _ _ _ _ _ _ _ _ . _ _ _ . _ _ . - - . - , _ . . _ , , . . _.,y,_ ,,__.,,.y , . . , _ .
i ; 1 l i The preoperational portion of the program was initiated in i May, 1980 and was completed on February 27,. 1987 to establish the baseline for the local . radiation l environment. Assessment of the operational impact of the. t Clinton Power Station on the radiation env.tronment is j based on data ~ collected since the . beginning of reactor , 4 operation. The operational phase implements confirmatory l measurements to verify that the in-station controls for , t the release of radioactive material are functioning as i designed. ! 1 a j Illinois Power Company maintains a contract with Teledyne - i Brown Engineering Environmental Services Midwest { i Laboratory -(TBEESE), formerly. Teledyne, Isotopes Midwest . Laboratory (TIE) , for analysis .of all radiological ! environmental samples. TBEESE is located in Northbrook,
- Illinois. Samples are collected by Illinois Power Company t personnel and shipped to TBEESE for analysis. After analysis, environmental samples are saved at TBEESE 'for a specified period of time in case additional analysis is required. Analytical results are reported monthly to company radiation protection personnel. .
Currsr.t regulatory guidance recommends evaluating direct - pathways, or the highest- trophic- level in a dietary 7 pathway, that contribute to an individual's dose. Figure i 3 - shows the basic pathways of gaseous and liquid ' radioactive offluents to man. The "important pathways" ' selected are based primarily on how radionuclides move through the environment and eventually expose individuals, as well as man's use of the environment. The scope of the program includes the monitoring of five environmental compartments: direct radiation atmospheric ' aquatic terrestrial environments ground and surface water. ; 1 Each pathway is . monitored at " indicator" and " control" locations. Indicator locations are generally within the 10-mile radius of the station. Control locations are located at least ten miles from the plant, far enough to be unaffected by plant operations. An increase in dose - rate or radioactive material concentration at an ir.dicator ; location may be due to plant operations. l

i : ! B. Direct Radiation Monitoring : ! Radionuclides present in the air, and those deposited in ; i or on the ground cause human exposure by immersion in the ! atmosphere or by deposition on the ground. TLDs l (thermoluminescent dosimeters) are used to measure the . l ambient gamma radiation field at many locations around the l
- Clinton Power Station. i
! TLDs are crystalline devices that store energy -when they f j are exposed to radiation. They can be processed months i after exposure with minimal loss of information. This ! makes them well suited for quarterly environmental
- radiation measurements.
s A During processing, the stored energy is released as light ! ! and measured by a TLD reader. The light' intensity is ' j proportional to the radiation dose the TLD received. The . TLDs used in monitoring around the Clinton Power Station i l are easily capable of measuring environmental levels of j
- radiation, approximately 20 mrem per quarter. '
) Monitoring stations are placed near the site boundary and
- approximately five miles from the reactor, in locations i representing the sixteen compass sectors. Other locations
; are chosen to measure the radiation field at places of
- special interest such as nearby residences, meeting places j and population centers.
Control sites are located further than ten miles from the l site, in areas that should not be affected by plant operations. I
- TLD measurements register the gamma ray exposure in j milliroentgen (mR). For reporting purposes mR is l numerically equivalent to arem. Consequently the terms !
are used interchangeably. ! 1, 1 j A total of 342 TLD measurements were made in 1994. The average quarterly dose at indicator locations was 18.2 ; arem. These quarterly measurements ranged from 14.0 to i 23.0 arem. At control locations the average quarterly
; dose was ' 17.8 arem. These quarterly control measurements ranged from 15.7 to 20.3 area. ! Figure 8 compares the ,1994 quarterly TLD results with preoperational TLD quartorly averages.
i l Average doses (12 standard deviations), broken down by calendar quarter, are shown in Table 5 for both indicator 1 and control locations. i 43 )

- i i The Clinton Power Station utilizes a man-made lake as the j source of cooling water and returns the-used cooling water ,
j to the same lake while- most nuclear power stations use once-through flow from a river, the ocean or a . body of :
- water auch larger than Clinton Lake. - When radioactive j j liquid offluents are discharged from the 'Clinton Power *
! Station into the cooling water outfall, radioisotopes with 'i l long half-lives could build up as.the same. water is reused : j on successive trips through the plant. This water' travels : e from the plant, into the eastern arm of the lake, .then !
- j. into the northern arm of the lake and back into the plant. >
j Although the only user of Clinton Lake as of !
- drinking water is the Clinton Power Station, . athe ' source lake is a ,
- major recreational facility, . used for fishing, sw1JERing, j water skiing, boating and hunting. ,
- .Clinton Lake constitutes the environmentr *
- exposure pathway for radioactive primary, materia ls in liquid i
< effluents.. Aquatic monitoring provides for.the collection i
- of fish, shoreline and bottom sediments,. and periphyton ,
. samples to detect the presence of any radioisotopes ; i related to operation of the Clinton Power Station. These " , samples are analyzed for naturally occurring and man-made
- radioactive materials. Both indicator and control ;
! locations were sampled ' during . 1994. . Indicator samples ; j were taken from various locations on Clinton Lake and the 4 control samples were taken at Lake Shelbyville which is : l approximately 50 miles south of Clinton Power. Station. 3 i Aquatic monitoring samples are collected by personnel from I i the Field Biology Laboratory of the Environmental Affairs j Department of Illinois Power. Company. l, Ziah l Samples of fish are collected from Clinton Lake and Lake i Shelbyville. In both lakes the samples include largemouth j bass, crappie, carp and bluegill.' These ' species are the i fish -most commonly harvested ~frot. the . lakes by sport
- j. fishermen. Fish ingest sediments during bottom feeding, a or prey on other organisms which ingest sediments or i j otherwise retain . radionuclides. Radiological analyses of these fish samples provide information on the potential' t '
l ingestion of radionuclides by humans' via the aquatic 1 pathway. These samples are collected semiannually and 4 j analyzed by gamma spectroscopy. l t
- The results of gassa isotopic analysis on the fish samples 1 shewed ' the presence ,of naturally occurring K-40' in all i j
1994 . samples ranging from' 2.24 to 3.41 pCi/g '(wet). Preoperational K-40 concentrations ranged from 1.71 to j - 4.61 pCi/g (wet) . All other analytical results were.less j 2 3 53

! Samples of~ shoreline sediments are collected at six
- locations from Clinton Lake, at one location from the i Clinton Power Station lower settling pond and at one i j location from Lake Shelbyville. Radiological analyses 'of )
shoreline sediments provide information on the potential )
- shoreline exposure to humans and for determining long-term i j trends and accumulation.of long-lived radionuclides in.the i i environment. Samples' are collected semiannually- and i
analyzed ' for gross beta, gross alpha, Sr-90 and gamma i

) Aquatic Vegetation iPeriphyton1 ) samples of periphyton are c:ellected fron five locations in Clinton Lake and one location. in ~ Lake Shelbyville.
; Periphyton (attached algae) are collected from the 5
4 ) 55 l i
3 submerged surface of the- permanently anchored buoys or_ natural substrate. Periphyton absorb trace elements and radionuclides directly from' water, often concentrating them to levels much higher than the dilute concentrations - < that - occur .in the aquatic environment. This is because 4 most algae are coated with a carbohydrate jelly and have a large surface-to-volume ~ ratio. Cell. division usually occurs once every one or two days and, as a result, half of the cell wall is- a' new. surface' for sorption. Periphyton' represent one of'the earliest links in~the food. ' chain and provide information about- the amounts of radionuclides available to predators further up the food chain. Samples of . periphyton are collected every . two months between April and October (during the colder months growth is limited) at the indicator locations and semiannually at the control location and analyzed by gamma spectroscopy. - The results. of the gamma isotopic analyses' on periphyton j samples showed the following. concentrations of naturally-occurring radioisotopes: 4 Preop Range 1993 Range 1994 Range i fDCi/a drvi fDCi/a drv) fDCi/a dry)- ' Be-7 0.38 - 1.07 0.51 .2.71 0.10 - 1.42 K-40 0.74 - 6.82 0.81 - 6.1 0.25 - 4.76 . Cs-137 0.042 - 0.15 0.023 - 0.082 0.026-- 0.085 i one fission product, Cs-137, was detected ~in several periphyton samples. Concentrations for Cs-137 in 1994 ranged from 0.026 to 0.085 pCi/g ' (wet) . Preoperational I results for Cs-137 .showed concentrations ' ranging from 0.042 to 0.15 pCi/g (wet). The presence ~ of Cs-137 is attributed to previous nuclear weapons testing and atmospheric fallout from the accident at chernobyl. Periphyton analyses are included in the. Clinton Power station Environmental Monitoring Program because of their sensitivity to the presence of radionuclides in the aquatic environment due to bio-magnification. Using periphyton as biomonitors for radionuclides in aquatic ' systems can be a highly sensitive and qualitatively effective means of environmental monitoring around nuclear power plants that release radioactive l effluents to aquatic systems. It enables the Radiological Environmenta.1 Monitoring Program to determine the relative presence of radioactivity before it becomes a problem. 56
l E. Terrestrial Monitorina j In addition to the' direct' radiation, radionuclider present [ in the atmosphere expose individuals when deposited on
- surfaces (e.g., plants and soil) and . are subsequently
- ingested directly by man or indirectly by consumption of i animal products (e.g., meat and milk) . To monitor this l food pathway, samples of green leafy vegetables, grass, )
j- milk and meat are analyzed. I
- .i l Surface soil samples are collected and analyzed annually - ,
l at the sewage sludge application site to ensure ; radionuclides attributed to the operation.of Clinton Power _; j Station are not being land applied with the processed - 4 sewage sludge. Every three years, samples are taken at ! nine other locations to monitor the potential buildup of
- atmospherically deposited radionuclides. i i >
! Surface vegetation samples are collected from a number of , ! locations for the purpose of monitoring the potential .
- buildup of atmospherically- deposited radionucliden.
~
i Because the radionuclides of interest, with respect to the l l Clinton Power Station operations, are also present in the
- environment as a result of several decades- of worldwide j fallout or because they are haturally occurring, the i presence of these radionuclides is expected in all;of the ;
j, samples collected. ;
- t j The possible contributions of radionuclides from the i j operation of the Clinton Power Station are assessed by l l comparing the results of samples collected in prevalent
! downwind locations (north to north north-east of. the l plant) with control samples and- samples collected in j locations generally upwind of the plant. .In addition, the > 4 results of samples collected during 1994 were compared ! with the results of samples collected during the j preoperational program. In addition to naturally occurring radioisotopes, Sr-90 j and Cs-137 were found in a number of 1994 samples. l However, the concentrations of radionuclides in samples collected near the Clinton Power Station were comparable
- to the concentrations in samples collected at locations remote from the station. The presence. of these fission
- products is attributable to previous- nuclear weapons
- testing and fallout from the accident at Chernobyl. The i operation of Clinton Power Station had no measurable l contribution to the radioactive concentration of the
{ terrestrial environment. Hilk ! There is no known tsaercial production of milk for human consumption within a five-mile radius of the Clinton Power t j 57 a m, rm-

} These samples' 'are analyzed for " I-131, Sr-90 and gamma j isotopic activities. L The results of the analyses showed positive concentrations j j of K-40 and Sr-90 in all'1994 samples with-a range of 1100 i

Water Monitorina water monitoring provides for the collection of drinking water, surface water and ground water (well water) samples to detect the presence of any radioisotopes related to the operation of the Clinton Power Station. The only identified user of water from Clinton Lake for domestic purposes is the Clinton Power Station; all others potentially exposed to any radioisotopes . released inte surface' or_ ground water would not be affected for .several years. Samplas taken were analyzed for naturally occurring and man-made radioactive isotopes. Average gross beta concentrations in surface, drinking and ' wall water are presented in Table 8. Drinkina Water The Clinton Power Station domestic water system is the l only known direct user of water from Clinton. Lake for human consumption. A composite water sampler located in the service Building collects a small, fixed volume sample at hourly intervals. The sampler discharges. each sample into a cosmon sample collection bottle. Therefore,' the monthly sample analyzed by the contracted. laboratory service is a composite of the individual saeples. 62 l l

The 1994 results of the gross beta analyses ranged from 'I 0.8 to 8.6-pCi/1 at the indicator locations and 1.6 to 4.3 l pC1/1 at.the control location.- Preoperational gross beta- l activity. ranged from 1.1 to 7.6.pCi/1. These results are attributed to ' naturally occurring , K-40 suspended as fine sediment particles in. water.

Monthly surface water gross beta ' activity for the~ control and indicator locations are presented. graphically in Figure 12. ;
' Tritium analyses. performed on samples ranged from 186 to !
653 pCi/1. The preoperational' tritium concentrations ! ranged from 220 -to 330 pCi/1. As noted in reference , (EI87), previous nuclear weapons testing increased the. ; pre-1960 levels of . tritium (6-24 pCi/1) by a factor of : approximately fifty (300-1200). Since the - levels of tritium reported . fell within this range of the ' existing, l non-rcactor-related, natural inventory of tritium, it is : considered that these positive results were not associated ; with operation of the Clinton Power Station. i namma-emitting ~ radioisotopes were all -below the lower l limits of - detection, and there was no - iodine-131 detected ! in any surface water sample during 1994. Gross alpha. activity was detected in several- of the surface water samples analyzed. These results ranged from 0.5 to 5.4 pCi/1. Preoperational gross alpha activity ; ranged from 1.3 to 1.9 pCi/1. These results' were ' t attributed to naturally occurring radioisotopes, such as . U-238 and Ra-226, suspended as fine sediment particles in ; water. These results show no measurable change l'n radioactive material concentration in surface water due to operation l of the Clinton Power Station during 1994. ' 66

IV. ANNUAL LAND USE CENSUS A land use census is performed to ensure that changes in the use of areas at and beyond the site boundary are identified and that any necessary modifications to the REMP are made. The land use census is performed to identify within a distance of 5 miles (8 km), the locations in each of the 16 meteorological sectors of the nearest milk animals, the nearest residence and the nearest garden of greater than 500 square feet producing broadleaf vegetation. Also, the census shall identify within a distance of 3 miles (5 km), the
; location in pach of the 16 meteorological sectors of all milk animals and all gardens of greater than 500 square feet producing broadleaf vegetation.

5 , I i l Y. i METEOROLOGICAL CHARACTERISTICS i A. Description '!
- The climate of central Illinois is typical of the 1 Midwest, with cold winters, warm summers and frequent
, short-period fluctuations in temperature, humidity, 1 cloudiness and wind direction. The variability in central Illinois climate is due to its location in a 4
- confluence zone (particularly during the cooler months) ]
l between different air masses. The specific air masses ! which affect central Illinois include maritime tropical air which originates in the Gulf of Mexico; continental ! tropical air which originates in Mexico and the southern i Rockies; Pacific air which - originates in the eastern l 2 Nor*.h Pacific Ocean; and continental polar and l ! continental Arctic air which originates in Canada.
- Monthly streamline analyses of resultant surface winds
- suggest. that air reaching central. Illinois most
? frequently originates over the Gulf of Mexico from April through August, over the southeastern United States from September through November, and over both the Pacific Ocean and the Gulf of Mexico from December through March.
- The major factors controlling the frequency and
- variation of weather types are determined by the j movement of storm systems which conunonly follow paths
! along a major confluence zone between air masses. The confluence zone is usually oriented from southwest to northeast through the region and normally shifts in latitude during this period, ranging in position from I the central states to the United States - Canadian j border. The average frequency of passage of storm i systems along this zone is about once every 5 to 8 days. l These storm systems are most frequent during the winter and spring months, causing a maximum of cloudiness l during these seasons. l Winter is characterized by alternating periods of steady l' precipitation and periods of clear, crisp and cold ! weather. Springtime precipitation is primarily showery in nature. The frequent passage of storm systems,
- presence of high winds, and frequent occurrence of unstable conditions caused by the close proximity
- between warm, moist air masses and cold, dry air masses,
- j. result in this season's thunderstorms and on occasion,
! are the source of hail, damaging winds and tornadoes. } i L 79 1 l
h 1 i i Although storm systems also' occur during the fall
- months, the frequency of occurrence during these months l 4- is less than that of the winter or' spring months.
! Periods of dry weather characterize the fall season j . which ends rather abruptly with increasing storminess j' that usually begins in November.' r i >
- In contrast,. weather during the summer, months is j i characterized by weaker storm systems which tend to pass ;
to the north of Illinois. A major confluence zone- is j ! not present-in this region, and the region's weather is i characterized by much- sunshine interspersed with ! thunderstorms. Showers and thunderstorms are usually of. j the air mass type, although occasional outbreaks of. cold air bring precipitation and weather typical of that associated with the fronts and storm systems of the spring months.- ! When southeasterly and easterly winds are present in j central Illinois, they usually bring mild and wet j weather. Southerly winds are warm and showery,~ westerly 5 winds are dry with moderate temperatures, and-winds from i [ the northwest and north are cool and dry. j The prevailing wind is southerly at' the Clinton Power
, Station. The frequency of winds. from other directions is relatively well distributed. The monthly average j
wind speed is lowest during late summer and highest i during late winter and early spring. I ! The meteorological monitoring program began at Clinton
- Power Station on April 13, 1972. The _ meteorological i system consists of a tower 199-feet high with two levels
! of instrumentation, at the 10-meter and 60-meter levels. 1 Wind direction and speed at the two levels are measured ! by a combined cup and vane sensor. The temperatures at i these levels are sensed by an aspirated dual temperature
- sensor. One-half of the dual sensor at each elevation '
{ is used for ambient temperature while the other half is i used to provide a difforential temperature of the two ! levels. Dow-point is measured at the 10-meter level
- using an aspirated dow-point sensor. Precipitation is l j measured at ground level by a tipping bucket rai'n gage.- '
Meteorological monitoring instruments have been placed on the Clinton Power Station microwave tower at the 10-j meter level to act as a backup to the existing tower. l 1 1 Clinton Power Station meteorological data'is transmitted
- to the Main Control Room via a dedicated telephone line.
There the signals are received and converted to a _4 to l 20 milliamp signal and fed individually to a 1 microprocessor and chart recorders. The microprocessor . is part of the Clinton Power Station Radiation ' Y l 4- I H b . . . -- . --- - . _ .
Monitoring System. Meteorological data is available via the microprocessors in the Main Control Room, Technical Support Center and the Radiation Protection office. ) l The on-site meteorological tower obtains information ) that is valuable in determining plume dispersion by ; providing differential temperature, wind speed and i direction. Table 10 summarizes the seven stability classes, with unstable conditions dispersing a plume more than stable conditions. Table 11 compiles the total hours for different wind speeds for each stability class during 1994, at 10 meters and 60 meters.
