==SUMMARY==
i This report describes the Annual Radiological Environmental Monitoring Program (REMP) conducted near the Clinton Power Station (CPS) during the 1995 calendar year. The REMP was performed as required by the CPS Operating 1.icense issued by the United States Nuclear Regulatory Commission. The objective of the REMP is to assess any radiological impact upon       i the surrounding environment due to the operation of the Clinton Power Station.
During 1995, over 1,800 environmental samples were collected. These samples represented direct radiation; atmospheric, terrestrial, and aquatic environments; and Clinton Lake surface water and public drinking water supplies. More than 2300 analyses were performed on these environmental samples.

Results of the analyses showud natural radioactivity and radioactivity attributed to other
^
historical nuclear events. The radioactivity levels detected were similar to the preoperational
; levels. The CPS Preoperational REMP Report documented natural background radionuclides and man-made radioactivity in the environment surrounding CPS prior to plant operations.        !
l Radiological environmental measurements taken during 1995 demonstrated that operational and engineered controls on the radioactive effluents released from the plant functioned as designed. Any radioactivity that was detected in the environment at indicator locations was appropriately compared with both the measurements at controllocations (sample locations not affected by station operations) and preoperational results.

There were no radioactive liquid .eleases during 1995. Releases of gaseous radioactive           l materials were accurately measured in plant effluents. There were no gaseous releases that came close to approaching the limits specified in the CPS Offsite Dcse Calculation Manual       !
(ODCM). The highest calculated total body dose received by a member of the public due to the    i release of radioactive materials in gaseous effluents from Clinton Power Station was 0.00313 mrem.
All comparisons among operational data and preoperational data showed that the operation of Clinton Power Station had no measurable effect upon the environmentin 1995.                     l 1                                               l

INTRODUCTION l

II. INTRODUCTION 1
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. CIIARACTERISTICS 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).

The unit of activity is called the curie.       A one curie radioactive source undergoes 2.2 trillion lisintegrations per minute, but in the realm of nuclear       power      plant       effluents          and       environmental radioactivity,        this    is    a    large    unit.        Therefore,    two fractional units, the microcurie and the picocurie, are more commonly used.
I curie (Ci)          =   2,220,000,000,000 disintegrations / minute 1 millicurie (mci)    =    2,220,000,000      disintegrations / minute     l 1 microcurie (pCi)    =   2,220,000           disin tegrations/ minute I nanocurie (nCi)     =   2,220               disintegrations /minuto 1 picoenrie (pCl)     = 2.22                  disintegrations / minute The microcurie (uci) is one millionth of a curie (C1) 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 ari activity of one curie.                           But iodine-131 (I-131) with a half-life of 8.04 days only requires about 0.000008 grams to produce 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

radioactive decay and human metabolism factors, some                                                  !
radionuclides stay in the body for very short times while                                              l others remain for years.                                                                              j The amount of radiation do'se that an individual receives is expressed in rem.                                   Since human exposure to radiation              ;
usually involves very small exposures,                                         the millirem            l (mrem) is the unit most commonly used.                                      One millirem is one thousandth'of a rem.
I millirem = 0.001 Rem B. SOURCES OF RADIATION 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.

1 Radioactive elements have always           been a part of our planet and everything that has            come from the earth, including        our   own   bodies  is,   therefore,   naturally radioactive.
Natural Radionuclides In The Earth's Crust Potassium-40 (K-40)         Radium-226 (Ra-226)
Uranium-238   (U-238)       Radon-222   (Rn-222)
Thorium-232   (Th-232)      Lead-204    (Pb-204)
Examples of radioactive materials found in the Earth's crust today consists of radionuclides such as potassium-40, uranium-238, thorium-232, radium-226 and radon-222.
These radionuclides are introduced into the water, soil and air by such natural processes as volcanic activity, weathering, erosion and radioactive decay.
Some of the 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 undergo         radioactive   decay,   producing   new   naturally radioactive materials called " radon daughters".             These new materials, which are solid particles, not gases, can stick to surfaces such as dust particles in the 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, pressure,          soil   moisture,    rainfall,    snow    cover, atmospheric conditions,          and  season. Radon can    move through cracks and openings into basements of buildings and become trapped in a small air volume indoors.            Thus, 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 contribute 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.
About three hundred cosmic rays originating from outer space pass through each person every second.

Cosmic-Ray-Activated Radionuclides Beryllium-7    (Be-7)        Tritium         (H-3)
Beryllium-10 (Be-10)         Sodium-22       (Na-22)
Carbon-14      (C-14)        Phosphorus-32 (P-32)
'1he interaction of cosmic rays with atoms in the earth's atmosphere produces radionuclides such as Beryllium-7, Beryllium-10,     carbon-14,     tritium,     and     Sodium-22.
Portions of these radionuclides become deposited on land or in water while the remainder stay suspended in the atmosphere.
Consequently, there are natural radioactive materials in the   soil,   water,   air    and building materials that contribute to radiation doses to the human body. Natural drinking water contains trace amounts of uranium and radium; milk contains measurable amounts of potassium-40.
Sources    of   natural     radiation    and    their    average contributing radiation doses are summarized in Table 1.
Figure 1 graphically shows the percentage contribution from principal sources of radiation exposure to the general population of the United States.               Radiation exposure levels from natural radiation fluctuate with time and also can vary widely from location to location.
The average individual in the United States receives approximately three hundred mrem per year from natural sources.
In some areas of the country,          the dose from natural radiation    is   significantly     higher.      Residents of 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 thousand feet in elevation above sea level, an individual will receive an additional one mrem per year from cosmic radiation.      In   several    areas of the world, high concentrations of mineral deposits result in natural background radiation levels of several thousand mrem per year.
In addition to natural background radiation, the average 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 160 million people in the United States are exposed to medical or dental X-rays in any given year.          The annual dose to an individual from such irradiation averages 53 mrem.

Smaller doses from man-made sources come from consumer products      (e.g.,     television,     smoke      detectors, fertilizers), fallout from prior nuclear weapons tests, 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.

Strontium-89 (Sr-89)     Cesium-137    (Cs-137)
There   are    approximately    two   hundred    radionuclides prod' iced 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, strontium-89, strontium-90, and cesium-137.

C DESCRIPTION OF TIIE CLINTON POWER STATION The Clinton Power Station is located in Harp Township,           l DeWitt County, Illinois.        It is approximately six miles    I east'of Clinton, Illinois.                                       ;
The   station,    its   V-shaped cooling lake,         and   the surrounding Illinois Power Company-owned land encloses 14,_32 acres.      This includes the 4,895-acre, man-made cooling lake and about 90 acres of privately owned property. The plant is sited on approximately 150 acres       i on the northern arm of the lake.             The cooling water   i discharge flume, which discharges to the eastern arm of the lake, occupies an additional 130 acres. Although the         ;
nuclear reactor, supporting equipment, and associated electrical generation and distribution equipment lie in Harp Township, portions of the 14,182 acres lie in Wilson, Rutledge, DeWitt, Creek, Nixon and Santa Anna Townships.
The cooling lake was formed by constructing an earthen           l dam near the confluence of Salt Creek and the North Fork of Salt Creek. The resulting lake has an average depth of 15.6 feet, and includes an ultimate heat sink of about 590   acre   feet.      The ultimate heat sink provides sufficient    water   volume and cooling capacity            for approximately thirty days of operation without makeup            !
water.
Through   arrangements with the Illinois         Department of Conservation,    Clinton    Lake and much        of   the   area immediately adjacent to the lake are used for public recreation    activities,     including    swimming,    boating, water-skiing,     hunting    and     fishing.       Recreational facilities exist at Clinton Lake and accommodate up to 11,460 people per day during peak usage periods.             The outflow from Clinton Lake falls into Salt Creek and flows 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 Grafton, Illinois.      The nearest use of downstream water for drinking purposes is 242 river miles downstream of Clinton Lake at Alton, Illinois, as verified from the Illinois Environmental Protection Agency Public Water Service. Although some farms in the Salt Creek drainage area downstream of Clinton Lake use irrigation, the irrigation water is drawn from wells, not from the waters of Salt Creek.
Approximately 810,000 individuals live within 50 miles of the Clinton Power Station.        Over half are located in the major metropolitan centers of Bloomington-Normal (located about    23   miles    north     northwest),   Champaign-Urbana (located about 31 miles east), Decatur (located about 22 12

N miles south southwest) and Springfield (located about 48 miles west southwest) . The nearest city is Clinton, the county seat of DeWitt County. The estimated population.of Clinton is about 8,000 people.         Outside of the urban areas, most of the land within 50 miles of the Clinton Power Station is used for farming.        The principal crops
;         grown are corn and, soybeans.
D. NUCLEAR REACTOR OPERATIONS
;         The fuel of a nuclear reactor is made of the element                     '
uranium in the form of uranium oxide.
The fuel produces power by tne process called " fission".                In fission, the uranium atom absorbs a neutron and splits to produce fission products, heat, radiation and free neutrons.                The   j free neutrons travel in the reactor core and further                      l absorption of neutrons by uranium permits the fission                     !
process to continue.      As the fission process continues,
,         more fission products, radiation, heat and neutrons are l         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 The fission products are predominantly radioactive. They are unstable elements that emit radiation as they change from unstable to stable elements.       Neutrons that are not absorbed by the uranium fuel may be absorbed by stable 1
atoms in the materials that make up the components and structures of the reactor.      In such cases, stable atoms often become radioactive.          This   process is called
          " activation" and the radioactive atoms which result are called " activation products".

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

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 used to drive a turbine which is coupled to a generator, thereby completing the conversion of the energy released during fission to electricity.
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 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.
E. CONTAINMENT OF RADIOACTIVITY During     operating     conditions,      essentially                     all radioactivity is contained within the first of several barriers     that    collectively     prevent      escape                  of radioactivity to the environment.
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 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. The Containment Building has steel-lined, four-foot-thick reinforced concrete walls which completely enclose the reactor pressure vessel and vital auxiliary equipment.
This structure provides a third line of defense against i

G. RADIOACTIVE WASTE PROCESSING i
In a normal operating nuclear power plant, radioactive liquid and gaseous wastes are collected, stored and processed through treatment systems to remove or reduce                                  l most of the radioactivity (excluding tritium) prior to reuse within the plant or discharge to the environment.
These processing systems are required by the Clinton 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).
19

The liquid waste treatment systems consist of filters, demineralizers and evaporators. Liquid wastes are routed through the waste evaporators                        to~ be degassed and distilled thereby reducing their volume and~ concentrating their radioactivity. The distillates are further treated through demineralizers and filters and transferred to the waste evaporator condensate storage tanks.                     Liquid wastes are processed through the appropriate portions of the liquid waste treatment system to provide assurance that the releases of radioactive materials in liquid offluents will be kept ALARA.
Liquid wastes are discharged into the plant cooling water stream which varies from approximately 5,000 gallons per 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 discharge canal before it enters Clinton Lake east of DeWitt County Road 14.
The Clinton Power Station Offsite Dose Calculation Manual requires that liquid effluents 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 effluent 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 mini =n= flow) and 1/1890 (for maxinnun flow) of their original value before the water enters Clinton Lake.
The    concentrated                  radioactive  solids   captured      in  tim liquid waste treatment system are processed and stored on-site or shipped off-site for disposal at licensed low-level waste disposal facilities.
The gaseous effluents from the main condenser are held up 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.
If gaseous effluents in the ventilation exhaust system for the Containment Building and for the Secondary containment structure exceed conservatively set levels, they    are                  processed through charcoal beds and. high efficiency particulate air filters in the Standby Gas Treatment                    system   before   being   discharged       to   the environment.
This combination of filters and charcoal beds is rated to be 95% efficient for removing iodines and greater than 99% efficient for removing particulate material larger than one micron (one millionth of an inch) in diameter.                          -

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. PROGRAM DESCRIPTION The Clinton Power Station is            required    to maintain a radiological       environmental       monitoring      program        in accordance with the Code of Federal Regulations Title 10, Section 20.1501 and Criterion 64 of CFR (CFR)         Title 10, Part 50, Appendix A. The program was dqveloped using the following guidance published by the United States Nuclear Regulatory Commission (USNRC):
          => Regulatory      Guide   4.1,    " Programs    for     Monitoring Radioactivity in the Environs of Nuclear Power Plants"
          => USNRC     Radiological      Assessment     Branch      Technical Position    on   Radiological    Environmental       Monitoring (1979)
The Radiological Environmental Monitoring Program is an extensive program of sampling, measuring and analyzing that was instituted to monitor the radiological impact of reactor operation on' the environment.           Objectives of the program include:
0 identification,    measurement and evaluation of existing radionuclides in the environs of the Clinton Power Station and fluctuations in radioactivity levels which may occur 0 evaluation of Clinton of the measurements to determine the impact Power Statinn operations on the local radiation environment 0 collection      of data     needed    to   refine    environmental radiation    transport    models     used    in   offsite    dose calculations 0 verification        that  radioactive      material    containment systems   are     functioning    to   minimize    environmental releases to levels that are ALARA 0 demonstration of compliance with regulations and the Clinton Power Station Offsite Dose Calculation Manual.
Implicit in these objectives are tne 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.

direct radiation atmospheric aquatic terrestrial environments ground and surface water.
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                ;
i rate    or radioactive material concentration at an indicator location may be due to plant operations.

B. Direct. Radiation Monitoring Radionuclides present in the air, and those deposited in or on the ground cause human exposure by immersion in the atmosphere    or   by   deposition   on- the   Jround. TLDs (thermoluminescent dosimeters) are _ used to measure the ambient gamma radiation field at many locations around the Clinton Power Station.
TLDs   are crystalline devices that store energy when they are exposed to radiation.       They can be processed months after exposure with minimal loss of information.          This makes    them well suited for quarterly environmental radiation measurements.
During processing, the stored energy is released as light and measured by a TLD reader.          The light intensity is proportional to the radiation dose the TLD received. The TLDS used in monitoring around the Clinton Power Station are easily capable . of measuring environmental levels of radiation, approximately 20 mrem per quarter.
Monitoring stations are placed near the site boundary and approximately five miles from the reactor, in locations 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 and population centers.
Control   sites are located further than ten miles from the site, in areas that should not be affected by plant operations.
TLD   measurements    register the gamma ray exposure in milliroentgen     (mR). For   reporting   purposes mR is numerically equivalent to mrem.         Consequently the terms are used interchangeably.
A total of 344 TLD measurements were made in 1995.         The average quarterly dose at indicator locations was 17.9 i    mrem. These quarterly measurements ranged from 11.8 to 25.0 mrem.      At control locations the average quarterly dose was 17.8 mrem. These quarterly control measurements ranged from 14.2 to 22.4 mrem.
}
Figure 8 compares the 1995 quarterly TLD results with preoperational TLD quarterly averages.
Average doses (i2 standard deviations), broken down by calendar quarter, are shown in Table 5 for both indicator and control locations.

C. Atmospheric Monitorina                                             l The inhalation and ingestion of radionuclides in the air is a direct exposure pathway to man.             A network of ten active air samplers around the Clinton Power Station monitors this pathway.          There are nine indicator air sampling stations strategically located in areas which are most likely to indicate effects due to the release of radioactive effluents from the Clinton Power Station. The control location is located approximately 16 miles south of the plant in an area which is likely to be independent          l of   the   effects    of   station     operations.      Historical meteorological data indicates this control location is normally upwind from the plant.
No   contribution .to      the general level of airborne particulate radioactivity could be identified as a result of station operations during 1995. The radioactivity that          i was detected is normally found in the environment and is           '

D. Acuatic Monitorino The Clinton Power Station utilizes a man-made lake as the source of cooling water and returns the used cooling water to the same lake while most nuclear power stations use once-through flow from a river, the ocean or a body of water much larger than Clinton Lake.                                                                                                       When radioactive liquid effluents are discharged from the Clinton Power Station into the cooling water outfall, radioisotopes with long half-lives could build up as the same water is reused on successive trips through the plant.                                                                                                    This water travels from the plant, into the eastern arm of the lake, then into the northern arm of the lake and back into the plant.
Although the only user of Clinton Lake as a source of drinking water is the Clinton Power. Station, the lake is a major recreational facility, used for fishing, swimming, water skiing, boating and hunting.
Clinton                                                    Lake                                         constitutes            the primary . environmental exposure pathway for radioactive materials in liquid effluents. Aquatic monitoring provides for the collection of fish, shoreline and bottom sediments, and periphyton samples                                                to detect the presence of any radioisotopes related to operation of the Clinton Power Station. These samples are analyzed for naturally occurring and man-made radioactiva                                                                        materials.                                Both  indicator    and  control locations were sampled during 1995.                                                                                                       Indicator samples   _
were taken from various locations on Clinton Lake and the control samples were taken at Lake Shelbyville which is approximately 50 miles south of Clinton Power Station.
Aquatic monitoring samples are collected by personnel from the                             Field                                             Biology                            Laboratory of the Environmental Resources Department of Illinois Power Company.
Fish Samples of fish are collected from Clinton Lake and Lake Shelbyville.                                                                            In both lakes the samples include largemouth bass, crappie, carp and bluegill.

Fish ingest sediments during bottom feeding, or prey on other organisms which ingest sediments or otherwise retain radionuclides. Radiological analyses of these fish samples provide information on the potential ingestion                                                         of                         radionuclides                    by  humans   via  the  aquatic pathway.

Naturally occurring radioisotopes, such as K-40, Ra-226 and Pb-212, were    present in samples, taken at both indicator and control Llocations.             Cesium-137, _ a fission product, was detected at an indicator location.

Acuatic Vecetation (Perichyton)
Samples of periphyton are collected from five locations in Clinton Lake and one location in Lake Shelbyville.
Periphyton (attached algae) are collected' from the 55 l

submerged surface of the permanently - anchored _ buoys or natural substrate.             Periphpton 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 most algae are coated with a carbohydrate jelly.and have a large      surface-to-volume                ratio.      Cell      divisiori 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.
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.                                                l t

The presence of Cs-137 is attributed           to previous             nuclear       weapons    testing and atmospheric fallout from the accident at Chernobyl.

E. Terrestrial Monitorino In addition'to the direct radiation, radionuclides present
         , in the -atmosphere e'xpose individuals when deposited on surfaces (e.g., plants and soil) and are subsequently
 !-        ingested directly by man or indirectly by consumption of 2
animal products (e.g., meat and milk) .                                 To monitor this 4
food pathway, samples of green leafy vegetables, grass, L        ,
milk and meat are analyzed.

;          radionuclides attributed to the operation of Clinton Power Station are not being land applied with the processed
;          sewage . sludge.      Every three years, samples are taken at j
nine.other locations to monitor the potential buildup of l          atmospherically deposited radionuclides.
I-
;          Surface vegetation samples are collected from a' number of
,          locations for the purpose of monitoring the potential i
buildup       of    atmospherically                          deposited . radionuclides.
Because the radionuclides of interest, with respect to the l'         Clinton Power Station operations, are also present-in the environment as a result of several decades of worldwide 1
fallout or because they are naturally occurring, the l          presence of these radionuclides is expected in all of the l          samples collected.                                         _
The      possible   contributions                         of   radionuclides    from           the i
operation of the Clinton Power Station are assessed by
:          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 locations generally upwind of the plant. In addition, the results of samples collected during 1995 were compared with the results of                          samples            collected    during             the preoperational program.
In addition to naturally occurring radioisotopes, Sr-90 was found in a number of 1995 samples.. 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 this fission product is attributable to previous nuclear weapons testing and fallout from the accident at Chernobyl. The operation of Clinton the Power Station had no measurable contribution to radioactive      concentration                         of    the    terrestrial environment.
Milk There is no known commercial production of milk for human
    .      consumption within a five-mile radius of the Clinton Power 57

l   Station.      Milk samples are collected from a dairy located l
about 14 miles west southwest of the station and goat milk is collected from a           family residence 3.5 miles south           ,
southwest of the station (twice a month during May through October and once a month during November through April) .
These samples are analyzed for I-131, Sr-90 and gamma isotopic activities.
The results of the analyses showed positive concentrations of.K-40 and Sr-90 in all 1995 samples with a range of 1100 to 2160 pCi/l for K-40 and 0.9 to 2.4 pCi/l for Sr-90.
Preoperational       activity of K-40 in milk ranged from 706 to 1375 pCi/1.      Strontium-90 analysis in milk was added to the REMP during the operational phase of the program, therefore there were no preoperational data for this isotope.       I-131 was not detected in any milk sample ~
obtained     during     1995. Figure    10 presents    the Sr-90 results graphically.
Grass In addition to milk samples, grass samples are collected at three indicator locations and at two control locations.
These samples are collected twice a month during May through October and once a month during November through April (when available) .          These samples are analyzed for gamma isotopic activity including I-131.

i F. Water Monitorina l
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 into l
'       surface or ground water would not be affected for several years.
Samples taken were analyzed for naturally occurring and man-made    radioactive    isotopes.      Average gross beta concentrations in ' surface, drinking and well water are presented in Table 8 at the end of this section.
Drinkina Water 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 common sample collection bottle. Therefore, the monthly sample analyzed         l by the contracted laboratory service is a composite of the individual samples collected throughout the month. The            !
monthly composite sample is analyzed for gross alpha,              i gross beta and gamma isotopic activities.         A portion of each monthly sample is mixed with the other monthly samples collected during each calendar quarter.               The i quarterly composite sample is analyzed for tritium.
Gross beta activity ranged from 1.2 to 2.3 pCi/1. These levels are attributed to very fine particles of sediment containing    K-40 which are not removed during the chlorinating and filtration process.          Monthly drinking water 11.
gross  beta  concentrations    are  presented   in Figure One    gross    alpha    analysis     indicated    0.6     pCi/1.
Preoperational result were all below the lower limits of detection except for one result which was 0.4 pCi/1. This result    can   be    attributed     to   naturally     occurring radioisotopes, such as U-238 and Ra-226, suspended as fine sediment particles in water.
The results of all analyses for tritium and gamma-emitting radioisotopes were     all   less  than the    lower limit of detection.
These results show no measurable offects on drinking water resulting from operation of the Clinton Power Station during 1995.

Two of the composite samplers are located upstream from          l Clinton Power Station and are unaffected by plant liquid         '
releases downstream. The two other composite samplers are positioned at the locations most likely to be affected by        I plant operations (one samples the intake water to the Circulating Water Intake Structure and the other samples the water at the start of the plant discharge flurr.e) .        j l
Monthly grab samples are collected from two indicator locations and one control location on Clinton Lake.
Surface water samples are analyzed for gross beta,        gamma isotopic and tritium activities.       Additional analyses for  ,
gross alpha activity are performed on the upstream water        I samples. Additional analyses for gross alpha activity and I-131 activity are performed on water samples taken from the   discharge   flume. Tritium analyses    are performed monthly on samples from the intake structure water samples      ;
and the upstream composite water samples, and quarterly from composites of monthly samples at the other locations.
The 1995 results of the gross beta analyses ranged from 1.2 to 5.2 pCi/l at the indicator locations and 1.0 to 3.1 pCi/l at the control location.      Preoperational gross beta 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.      Other types of samples have confirmed the presence of K-40 in Clinton Lake shoreline and bottom sediments.       Monthly surface water gross beta activity for the control and indicator locations are presented graphically in Figure 12.
Tritium analyses performed on samples were all less than LLD. The preoperational tritium concentrations ranged from 220 to 330 pCi/1.         As noted in reference (EI87),

l G. Quality Assurance Procram l      To are establish confidence that data developed and reported accurate   and   precise,    all  REMP  activities   are l      incorporated   into   the Illinois Power     Company Quality Assurance (QA) program of audits and surveillances.        The Quality Assurance program requires:
Participation in intercomparison programs,      such as the EPA cross-check program.
An annual audit of the analysis laboratory functions and facilities.
l Periodic review of the Clinton Power             Station procedures specifying sampling techniques.
Duplicate analysis of every tenth sample assayed (not including TLDs).        This requirement is to check laboratory precision.
The routine counting of quality control samples.
Approximately ten percent of the total number of counts performed are to be quality control counts.
The analytical results provided by the laboratory were routinely reviewed by the Radiological Environmental Group of the Radiation Protection Department to ensure the            _
required minimum sensitivities have been achieved and the proper analyses have been performed.
Teledyne Brown Engineering Environmental Services Midwest Laboratory (TBEESML) participates in the Environmental Protection Agency cross-check program.            The  TBEESML participant code in the cross-check program is  CA.
Participation in this program provides assurance that the laboratory is capable of meeting widely-accepted criteria for radioactivity analysis.
Results of the 1995 cross-check program are shown in Appendix D.
H. Chances to the REMP Durino 1995 Occasionally changes to the Radiological Environmental Monitoring Program are necessary to improve the monitoring of the environmental exposure pathways. These changes may i
result from items identified during the performance of the Annual    Land  Use   Census,    revised requirements, Quality Assurance audits ornew or        regulatory supplemental periodic and long-term sampling and analyses.

     .            .During 1995, CL-92 and CL-93 were deleted from the program. Also, an additional type of broadleaf vegetation
'                  (collard greens) was grown to supplement the current types of vegetation grown (cabbage, lettuce, Swiss chard, kale greens and spinach).

ANNUAL LAND USE CENSUS

l l
l 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 hre 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 animalo,                the nearest residence and the nearest garden of greater tnan 500 square feet producing broadleaf vegetation. Also, the census shall identify within a distance of 3 miles                         (5 km),     the location in each of the 16 meteorological sectors of all milk animals and all gardens of greater than 500 square feet producing broadleaf vegetation.

The 1995 Land Use Census was conducted during the growing season satisfying the CPS Offsite Dose Calculation Manual requirements.        Over 170 residences were surveyed by either direct contact, mailed in questionnaire, telephone, or direct observation.       Data for this report was obtained using the following means:
o Performed door-to-door solicitation of residences / land owners identified in the 1994 Annual Land Use Census and                      i the 1994 DeWitt County plat book.                     If a resident was       1 73

unavailable' for questioning, a questionnaire was placed on their door to have them fill out and mail back.              ,
o Performed telephone solicitation of persons who were unavailable during the door-to-door survey and didn't mail back their questionnaire.
o By direct observation of land. when the aforementioned methods were unsuccessful.      If an individual was unable to be contacted, data from the previous year was used.
* Contacted several state and local agencies.
The 1995  Land Use Census results were examined to ensure that the   REMP   will. provide representative measurements of radiation   and radioactive      materials   in     those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures to the general public resulting from Clinton Power Station operations ~.
On the basis of the examination of the 1995 Annual Land Use Census results, no changes to the REMP were made.

Exceptions to the REMP During 1995 Data from the radiological analysis of environmental samples are routinely reviewed and evaluated by the Clinton Power Station Radiological Environmental Group.                    This data is checked for LLD compliance, anomalous values, quality control sample agreement,        and any positive results which are inconsistent with expected results or which exceed                       any Offsite Dose Calculation Manual reporting levels. Reporting                      i levels    for    radioactivity     concentrations        in   environmental samples required by the Clinton Power Station Offsite Dose Calculation Manual are listed in Table A-1.
If    an inconsistent result occurs,                an investigation        is initiated which may consist of some of the following actions:
Examine     the     collection       data    sheets ~ for    any indication    of     collection       or   delivery     errors, tampering, vandalism and equipment calibration or malfunctions     due     to      electrical    power    failore, weather conditions, etc.
l Perform statistical tests Examine previous data for trends Review other results from same sample media and different sample media Review control station data Review quality control or duplicate sample data                      j Review CPS effluent reports i
Recount and/or reanalyze the sample Collect additional samples as necessary During 1995, no investigations were performed as a result of reaching   any Offsite pose calculation Manual (ODCM) reporting                   l levels. A?1 sample analysis required by the ODCH achieved                     l the LLDs      specified   by ODCM Table           5.1-3.      Sampling 'and       !
analysis exceptions are listed in Table A-2 of this appendix.                     !

Column 1:
The Unit of Measurement describes all the numerical values for LLD, Mean and Range reported for a particular sample medium. For example: the Gross Beta LLD in AIR PARTICULATES is 0.010 pCl/m3 Abbreviations used are: pCi/m                3 ,
picocurie per cubic meter of sampled air; mR/ quarter = exposure measured for calendar quarter period; pCi/1 = picoeurie per liter of sample; pCi/g = picoeurie per gram of sample.
Column 2:
The Types of Analyses are det.cribed as follows. Gamma Spec = measurement of each radioisotope in a sample using Gamma Spectroscopy; Gross Betas and Gross Alphas = measurement of the radioactivity in a sample by measurement of emitted betas and alphas - no determination of individual radioisotopes is possible; Tritium = measurement of tritium (H-3) is sample by liquid scintillation counting method; TLD = direct measurement of gamma exposure using thermoluminescent dosimeters.
Column 3:
LLD reported is the highest of those reported for each of analysis during the year; tf all analyses reported positive values, no LLD is reported.
i Column 4:
Samples taken at Indicator Locations during an operational radiological environmental monitonng program (REMP) reliably measure the quantities of any radioisotopes cycling through the pathways to man from the nuclear station. The
~
reported values are the mean or average for the year of all samples of that type which had values greater than the LLD.
                  "f' is the fraction of all the samples taken at all indicator locations for the medium which reported values greater than the LLD. Example: 7 results greater than LLD out of 15 samples taken would be reported 7/15. The Range is the values of the lowest to highest sample results greater than LLD reported at all the indictor locations for that medium.
Column 5:
The Mean, f-fraction and Range along with the name of the location, distance from the CPS gaseous efnuent stack in miles, and the letter (s) name of the compass sector in the diraction of the sample location from the CPS gaseous effluent    l stack. The location wth the highest annual mean is comparcJ to both indicator and control locations of the medium samples.
Column 6:
Control locations are sited in areas with low relative deposition and/or dispersion fadors Sample results are used as reference for the ce ntrollocation.
4 Column 7:
NRC Regulations (Branch Technical Position, Rev.1, November 1979) include a table of radioisotope concentrations that, if exceeded by confirmed sample measurements, indicate that a Nonroutine Reported Measurement exists. Such measurements require further investigation to validate the source.
