SUMMARY

CLINTON POWER STATION OPERATIONAL RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT FOR 1990 I. EXECUTIVE SUM]ih]d This report describes the Operational Radiological Environmental Monitoring Program (REMP) conducted during 1990 in the vicinity of the Clinton Power Station (the fourth year of the Clinton Power Station Operational Radiological Environmental Monitoring Program). The REMP was performed in 1990 as required by the Clinton Power Station Operating License issued by the United States Nuclear Regulatory Commission.

The purpose of the REMP is to assess any radiological impact upon the surrounding environment due to the j operation of the Clinton Power Station.

1 Over 1700 environmental samples were collected during 1990. These samples represented direct radiation; <

atmospheric, terrestrial, and aquatic environments; and Clinton Lake surface water and public drinking water supplies. More than 2200 analyses were performed on these environmental samples. Results showed that radioactivity levels were similar to the preoperational levels. The Clinton Power Station Preoperational Radiological Environmental Monitoring Report documented natural background radionuclides in the environment  !

surrounding Clinton Power Station prior to plant 1 operations.

I Direct radiation measurements were taken at 83 locations using thermoluminescent dosimeters. The average annual dose was 69 mrem. This is consistent with the annual average dose documented in the Preoperational Radiological Environmental Monitoring Report, 1980 - 1987.

Atmospheric monitoring results for 1990 were within the same range as environmental measurements made prior to the commercial operation of the Clinton Power Station (preoperational data). No radioactivity attributable to the operation of the Clinton Power Station was detected in any. atmospheric samples during 1990.

Terrestrial monitoring includes analyses of vegetation  !

samples, grass samples, milk samples, and meat samples, j Results of the analyses showed natural radioactivity and radioactivity attributed to other historical nuclear events (i.e., fallout from nuclear weapons testing and the 1986 Russian reactor accident at Chernobyl). The radioactivity levels detected were consistent with the preoperational results.

I l=

l t

Aquatic monitoring includes analyses of fish samples, I lake bottom sediment samples, lake shoreline sediment samples and aquatic vegetations (periphyton) samples.

All sampled media, with the exception of one periphyton sample, showed that radioactivity levels were consistent with the levels in the preoperational program. One periphyton sample had a low level of-radioactivity attributed to the operation of Clinton Power Station. However, this result was well below any regulatory limit and was consistent with the activity released in liquid effluents.

Ground and surface water monitoring results were consistent with the results obtained during the preoperational program. .None of the 1990 samples showed radioactive material due to the. operation-of_the Clinton Power Station.

Releases of gaseous radioactive materials were accurately measured in plant-effluents during 1990. No release exceeded or even approached the limits specified in the Clinton Power Station offsite Dose Calculation Manual (ODCM). A total of 12.8 curies of gaseous radioactive effluents were. released.during 1990. This total includes 1.88 curies of tritium.

Releases of liquid radioactive materials were also accurately measured in plant effluents during 1990. As '

stated above for gaseous effluents,uno. release exceeded or approached the Clinton Power Station ODCM limits. A total of 2.63 curies of liquid radioactive effluents ,

were released during 1990. This total includes 2.60 l curies of tritium. 1 The highest calculated 1 total bodyidose received by a member of the_public due to the release of radioactive materials in gaseous and liquid effluents from Clinton Power Station was 0.0027 mrem.

14 Radiological-environmental measurements taken during. '

1990 demonstrated that_ operational and._ engineered .

controls on the radioactive-effluents released:from'the Clinton Power Station-functioned 1as' designed. ;Any radioactivity.that was detected in the environment at indicator locations was appropriately compared against=

both the measurements ~at-control locations (sample locations'not affected by . station' operations) and preoperational results.

All comparisons between 1990 operational' data ~and.

preoperational data showed that the' operation of -

3 INTRODUCTION

II. IETRODUCTION The following background information regarding basic radiation characteristics, plant operations, radioactive offluent controls and environmental monitoring is provided to assist the reader in reviewing this document. )

A. Characteristics of Radiation Atoms whose nuclei contain an excess of energy are called radioactive atoms. They releasc 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 have no charge, like neutrons.

The term " half-life" refers to the time it takes  ;

for half of a given amount of a radionuclide to decay. Some radionuclidos 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 activity of a radioactive source is the number of nuclear disintegrations (decays) of the source per unit of time. The unit of activity is 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 microcurie i and the picocurie, are more commonly used. The i microcurie (uci) is one millionth of a curie (Ci) '

and represents 2.2 million decays per minute. The picoeurie (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 j around the earth, l

?

o 1

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 0.003 grams to produce an activ'ity of one curie.

4 Any mechanism that can supply the energy necessary to ionize an atom, break a chemical bond, or alter the chemistry of-a living cell is 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,~the type, energy, and amount of radiation.must be considered.

External total body radiation involves exposure of all organs. Most background exposures arelof this form. When radioactive elements enter the body through inhalation or ingestion, their distribution:may not be uniform. For example, radioiodine selectively concentrates in the thyroid gland, whereas radiocesium_ collects in. 4, muscle and liver tissue, and radiostrontium collects in uineralized bone. The total dose to organs by a given radionuclide is also influenced a 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'which'an-individual F receives is expressed 11n rem. Since human  ;

exposure to radiation usually involves.very small-exposures, the millirem (mram) is the unit most commonly used. _one millirem is-one thousandth of a rem.

B. Sources of Radiation Exoosure' Many sources of radiasion exposure e'xist. The- .

l most common and loast controllable source is f background radiation from cosmic ~ rays and _

-terrestrial radioactivity-whichtmankind bas alwayse lived.with and always"will. LEvery seconn of our '

Radioactive elements have always been a part of our planet and everything which has come from the earth including our own bodies is, therefore, naturally radioactive. Radioactive materials found in the earth's crust today consist of such radionuclides as potassium-40 (K-40), uranium-238 (U-238), thorium-232 (Th-232), radium-226 (Ra-226) ,

and radon-222 (Rn-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 generai 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 radioactivo decay, producing new naturally radioactive materials called " radon i 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, altitude, soil porosity, temperature, pressure, soil moisture, rainfall, snow cover, atmospheric conditions, and season. It 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 these found outdoors. Building materials such as cinder blocks and concrete are radon sources. Radon can also be dissolved in well water and contribute to airborno radon in houses when released through showers or washing.

Dust containing radon daughter particles can be inhaled and deposited on the surface of an_ d 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. i The interaction of cosmic rays with atoms in the earth's atmosphere produces radionuclides such as Bery111um-7 (Be-7), Beryllium-10 (Be-10),

Carbon-14 (C-14), tritium (H-3), and Sodium-22 (Na-22). Portions of these radionuclides become deposited on land or.in water while the remainder stay suspended in the atmosphere.

S

l l

Consequently, there are natural radioactive materials in the soil, water, air and building materials which 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 percent contribution from 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 mrom 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 mrein por 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 comes 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 l dose to an individual from such irradiation averages 53 mrem. Smaller doses from man-made sources come from consumer products (television, smoke detectors, fertilizer) , 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 l

snow.

There are approximately two hundred radionuclides produced in the. nuclear weapon detonation processt a number of these are detected in fallout. The l radionuclidos found in fallout which produce most of the fallout radiation exposures to man are l iodine-131 (I-131), strontium-89 (Sr-89),

strontium-90 (Sr-90), and cesium-137 (Cs-137).

C. Descriotion of the Clinton Power Station The Clinton Power Station is located in Harp Township, DeWitt County, Illinois. It is approximately six miles east of the city of Clinton, Illinois.

The station, its V-shaped cooling lake, and the surrounding Illinois Power Company-owned land enclose 14,le2 acres. This includes the 4,895 acre man-made cooling lake and about 90 acres of privately-owned property. The Clinton Power Station is sited on approximately 150 acres 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 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 dam near the confluence cf 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-i 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, waterskiing 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 westerlyLdirection tor 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.

9

Clinton Lake at Alton, Illinois as verified in l July 1990 by the Illinois Environmental Protection l Agency Public Water Service. Although nome farms ,

in the Salt Crook drainage area downstream of Clinton Lake use irrigation, the irrigation water is drawn from wells, not from the waters of Salt Creek.

An estimated 810,000 individuals live within 50 miles of the Clinton Power Station. Over half of these are located in the major metropolitan contors of Bloomington-Normal (located about 23 miles north northwest), Champaign-Urbana (located about 31 miles east), Decatur (located about 22 miles south southwest) and Springfield (located about 48 miles west southwest). The n4arest city is Clinton, the county seat of DeWitt County, located about 6 miles west of the station. 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 are corn and soybeans.

D. Nuclear Reactor Ooerations The fuel of a nuclear reactor is made of.the element uranium in the form of uranium oxide. The fuel produces power by the. process called

" fission". In fission, the uranium atom absorbs a neutron (an atomic particle found in nature and produced by the fissioning of uranium in the reactor) and splits to produce fission products, heat, radiation and free neutrons., The free neutrons travel in the core; further absorption of neutrons by uranium permits the fission process to continue. As the fisslun 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 which drives a turbine generator to produce electricity. The fission products are predominantly radioactive; they are unstable elements which emit radiation as they change from unstable to stable elements. Neutrons which are not absorbed by the uranium fuel may be absorbed by stable atoms in the materials which make up the components and structures of the reactor. In such l cases, stable atoms often become radioactive.

l This process is called " activation" and the

! radioactive atoms which result are called

" activation products".-

j The reactor at the Clinton Power Station is a 1 boiling water reactor (BWR). . In this type of

! reactor the fuel is formed into small ceramic pellets which are loaded-into sealed fuel rods. -

The fuel rods are arranged in. arrays called ,

bundles which are supported within a massive steel l I reactor vessel.

s i

The spaces between the fuel rods'are filled with J water. The heat released during the fission of fuel atoms is transferred to the water surrounding the fuel rods'.. A type of pump which 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' i steam is used to drive a turbine which'is coupled- .

to a generator, thereby completing the conversion of the energy released during:fissionrto 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 1 vessel, corrosion allows trace quantities _of'the component and structure surfaces to get intoLthe-water. The corroded material.'also contains radioactive substances known as activated-I corrosion products.= Radioactive' fission'and.

activation products are normally-confined to the primary system although small-leakstfrom the primary system may occur. Figure-2_-provides'a basic. plant schematic for.the:Clinton Power- ,

! Station and shows the separation =of the= cooling i

! water from plant systems.  :

E. Containment'of Radioactivity Under: normal' operating conditions, essentiallyLall radioactivity is contained within the firstLof.

several barriers of'the primary--system:which collectively. prevent-escape of. radioactivity to the environment..

-The fuel: cladding -(meta 11 tubes)lprovides'the-first' barrier. The ceramicLfuel pellets arelsealed- l l within.zircaloy metal tubes. -There is alsmall; gap between the fuel'and the; cladding _wherenthe noble:

L gases and other volatile nuclidesTcollect.'

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 approximately four to seven inches thick which f 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 the uncontrolled release of radioactive materials to the environment. The massive concrete walls also serve to absorb much of the radiation emitted during reactor operation or from radioactive-materials created during reactor operations.

F. Sources of Radioactive Effluents In a normal operating nuclear power plant, most of the fission products are retained within the fuel and fuel cladding. However, the fuel manufacturing process leaves traces of uranium on the exterior of the fuel tubes. Fission products from the eventual fission of these traces may be released to the primary coolant.- other small ,

amounts of 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. component and structural surfaces which have been activated,-

also get.into the primary coolant. Many_ soluble fission and activation products such as radioactive iodines, strontiums, cobalts and cesiumsJare removed by demineralizers.in.the purification systems. The noble' gas fission -

products, activated atmospheric gases introduced with reactor.feedwater,;and some of the volatile fission products such as iodine-_and bromine, are-carried from the reactor : pressure - vesseloto 'the -

-ejectors or the condenser vacuum pump remove.thef gases from the condenser and_ transfer them to the '

Small releases of radioactive liquids from valves, piping, or equipment associated with the primary coolant system may occur in the containment, Auxiliary, Turbine, RadWaste and Fuel Buildings.

The noble gases become part of the gaseous wastes while the remaining radioactive liquids are collected in sumps and processed prior to release.

Processed primary coolant water that does not meet chemical specifications for reuse may also become waste water. These represent the principal sources of liquid affluents.

Table 2 summarizes the composition of radioactive effluents (gaseous and liquid) released _from the clinton Power Station during 1990. The highest calculated total body dose received by-a member-of the public due to the_ release of these radioactive -

materials was 0.0027 mrem. This is compared to ,

the 93 mrem per year received in Central Illinois )

due to-natural background radiation.

l G. Radikpctive Waste Processing l

In a normal operating nuclear pnwer plant, ,

radioactive liquid and gaseous wastes are I

' collected, stored and processed through treatment systems to remove or reduce most of the i radioactivity (excluding tritium) prior to reuse j within the plant or discharge to the environment.- j 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) .

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 j provide asourance that the releases of radioactive

  • i materials in liquid effluentsEwill be kept ALARA.

Liquid wastes are discharged into the plant i cooling water stream which varies frotn 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 J Manual requires that liquid effluents shall not contain a' higher concentration of any.racioisotope-than that set for continuous exposura.to the i general public. -This condition is satisfied at the point the liquid effluent is first introduced into the cooling water flow. _The additional ,

dilution which occurs in-the cooling water canal reduces the concentrations of radioisotopes-to '

between 1/73 (minimum flow) and 1/1890_of their original value before the water enters'clinton-Lake.

The concentrated radioactive solids captured in -

the liquid waste treatmont system are solidified and shipped off-site for disposal at-licensed-low -

L level waste-disposal facilities.-

, If gaseous effluents in the ventilation exhaust system for the containment Building and for the Secondary containment

'i 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.

MONITORING PROGRAM

III. NTAL MONITORING PROGRAM (REMP)

A. Proaram Descriotion ,

The Clinton Power Station is required to maintain a radiological environmental monitoring program in accordance with the Code of Federal--Regulations '

l (CFR) Title 10, Section 20.201 and Criterion 64 of CFR Title 10, Part 50, Appendix-A. The-program was developed 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. 4 Environmental Monitoring (1979) p i

The licensee has been notified of pending changes. ,

to the Code of Federal Regulations Title 10 Part i

20. These changes are currently scheduled to be implemented January 1, 1993. A preliminary i of the proposed changes indicates minor impa.roview ct on the Clinton Power Station Radiological l Environmental Monitoring Program.

The Radiological Environmental Monitoring Prcgram is an extensive program of sampling, measuring and- i analyzing that was instituted to monitor: tbe radiological impact of reactor operation on'the environment. Objectives of the. program include identification, measurement and evaluation of existing radionuclides in the environs of.the {

Clinton Power Station and fluctuations-in- '

radioactivity levels which may occur evaluation of the neasurements'to determine i the impact of the Clinton Power Station {

operations on the local radiation environment  !

collection of data.needed to~ refine environmental radiation transport models'used in offsite dose calculations-verification that radioactive mater'lal containment systems are functioning to.

demonstration of compliance with regulations and the Clinton Power Station offsite Dose calculation Manual (formerly the Radiological Effluent Technical Specification (RETS) requirrments which were moved to the ODCM in 1990). l t

Implicit in these objectives are the requirements to teer,d ar.d assess radiation exposure rates and radiceetl<ity concentrations in the environment that may :ontribute to radiation exposure to the public. se program consists of two phases, preoperational and operational. The preoperational portion of,the program (the program was initiated in May, 1980 and was completed on February 27, 1987) established the baseline for the local radiation environment. Assessment of the operational impact of the Clinton Power Ste. tion on the radiation environment is based on data collected since the beginning of reactor operation. The operational phase implements confirmatory measurements to verify the in-station controls for the release of radioactive material are functioning as designed. Figure 3 shows the basic pathways of gaseous and liquid radioactive effluents to man.

Illinois Power Company maintains a contrace with Teledyne Isotopes Midwest Laboratory (TIML) for analysis of all radiological environmental samples. TIML is located in Northbrook, Illinois.

Samples are collected-by Illinois Power company personnel and shipped to TIML for analysis. After analysis, environmental samples are saved at TIML for a specified period of time in case additional analysis is required. Analytical results are reported monthly to the clinton Power Station and reviewed by company radiation protection personnel.

Current regulatory guidance recommends evaluating direct pathways, or-the highest trophic level in a '

dietary pathway, that contribute to an' individual's dose. The "important pathways" are selected based primarily on how radionuclides move through the environment and eventually expose individuals, as woll as on man's use of the environment. :The scope of the program-includes 20-

l the monitoring of five environmental compartmentst

  • direct radiation

' atmospheric  :

  • aquatic  ;

' terrestrial environments  :

' ground and surface water. j Each pathway is monitored at " indicator" and 1

" control" locations. Indicator locations are a generally within the-10-mile radius of the j station. Control locations are located at least i ten miles from_the plant, far enough to be unaffected by plant operations. An increase in dose rate or radioactive material concentration at an indicator location may be dus to plant operations.

Locations of sampling stations are shown on maps in Figures 4 through 7. Table 3 provides a list of the sample codes for each sample medium and  !

Table 4 provides information on sample location, l media-sampled at each location, and a-brief description of each location where samples ~are taken. The location is listed according to  ;

distance (in miles) and the compass sector- t

-relative to the Station Heating, Ventilation and Air Conditioning (RVAC) stack.-

An on-site meteorological tower collects i information such as_ wind speed, wind direction and' air temperature at various levels. Meteorological monitoring is further discussed in Section V of ,

i B. Direct Radiation Monitorina; 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 ground. TLDs (thermoluminescent dosimeters) are used to measure the ambient gamma radiation field at many locations around the Clinton power 1 Station. TLDs are-crystalline devices that store "

energy when they are exposed to radiation. They can be processed months,after exposure with- l minimal loss of information. This makes them well <

suited for quarterly environmental radiation-measurements. During processing, the stored H]

energy is released asLlight-and measured by a TLD- -j reader. The light-intensity is proportional to  !

the radiation dose the;TLD received. The TLDs used in monitoring around theLClinton power-Station are easily capable of-measuring:

environmental levels of radiation, approximately_ j 20 mrem per quarter, j 1

Monitoring stations are placed near_the site -_ l boundary and approximately;five miles-from the 1 reactor, in locations: representing the sixteen compass sectors. Other' locations _are chosen to a ~

measure the radiation' field at. places of special interest such as nearby residences, meeting places and-population; centers.- Control' sites are located  ;

Site CL-34,. located 0.8 miles WNW of the. station, registered the-highest annualized dose: 85.5 mrem l during 1990. The elevated measurements are  !

E No contribution to the general level of-airborne particulate radioactivity could be identified as a result of station operations during 1990. The radioactivity that was detected is normally found in the environment and is consistent with expected concentrations of natural radioactivity and fallout from prior atmospheric nuclear weapons testing.

Mechanical air samplers are used to draw a continuous volume of air through two filters .

designed to collect particulates and radiciodines present in the atmosphere. The samplers are equipped with a pressure-sensing flow regulator to maintain a constant sampling flow rate of about one cubic foot per minute. The total volume is calculated based on the amount of-time the air sampler ran and its flow rate. The air sampling ,

~

equipment is maintained and calibrated by the Clinton Power Station personnel using reference j standards traceable to the National Institute.of Standards and Technology.

Air samples are collected weekly and analyzed for gross beta and I-131 activities. Quarterly all air particulate filters collected during that period are combined and counted for gamma isotopic activity. Since the intent of particulate sampling is to measure airborne radioactivity released from the plant, the-counting.of short- 1 lived daughters produced by the decayaof natural radon and thoron may mask plant contributions.

Therefore, the filters are not analyzed for at least five days after their collection to allow for the decay of'the short-lived daughters,  ;

thereby reducing their contribution'to the gross I beta activity.

A new air sempling location was added to the.

Clinton Power Station Radiological Environmental Monitoring Program in January 1990.' This air sampling station is located in the north sector at 0.9 miles. This indicator sample. location was added because the north sector has-historically had one of the highest annual average ground level D/Q (Radiciodine and Particulate Relative Disposition Factor) values.

Results of the gross beta airborne particulate analyses provided comparisons between indicator and control locations for the year, as well as comparisons between locations in relation to spatial and temporal differences. The calculated 46

i i

3 annual average was 0.021 gC1/m for all indicator locations and 0.022 pCi/m for the control location. These results are consistent with the preoperational averages for both indicatgr and control locations which were 0.027 pCi/m . The location with the highest annual average was control location CL-11 located 16.0 miles south of the Clinton Power Station. This locgtion had an average Ocncentration of 0.022 pCi/m . Individual location averages for the year are presented in Table 7.

Minor fluctuations in the gross beta concentrations were noted throughout the year.

The general trend for average weekly gross beta concentrations in the indicator locations correlated to the trend for control locations throughout the monitoring period. This correlation is evidenced by the similarity of the trends in the average monthly gross beta concentrations displayed in Figure 9. No significant difference was indicated between individual locations. Monthly averages for indicator and control' locations for the year are ->

presented in Table 8.

All gross beta concentrations for 1990 were within normal background levels and no increases were noted as a result of-the operation of the Clinton Power Station.

Naturally occurring Be-7 was the only gamma-emitting radionuclide detected in analyses of particulate filters.

D. &cuatic Monitoring The Clinton Power Station utilizes an artificial 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.

radioactive materials. Both indicator and control locations were sampled during 1990.. 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, the personnel from the Field Biology Laboratory of 'the Environmental Affairs 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. These species are the' fish most commonly harvested from.the lakes by sportsfishermen. . 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-53

-i aquatic pathway. These samples are collected- ti semiannually and analyzed 1by. gamma _ spectroscopy.  :

The results of gamma isotopic analysis on the fish- l samples showed the presence of naturally occurring-K-40 in all 1990-samples ranging from 2.24 to 3.08- ~i pCi/g (wet) . Preoperational K-40 concentrations ranged from 1.71 to 4.61 pCi/g (wet). . .All other.

analytical results were-less than the lower limit of detection (LLD) for each radionuclide.

Shoreline Sediments Samples _of shoreline sediments are collected at six locations from Clinton Lake, at one location-from the'Clinton Power Station lower settling pond ,

and at one location from Lake Shelbyville.- l Radiological analyses of-shoreline sediments q

Gross alpha activity in samples of shoreline sediments collected from all locations ranged from 4.0 to 5.5 pCi/g (dry) during 1990. This activity was attributed to naturally occurring radium isotopes and decay products present in soil. These values compare closely with the activity detected in the preoperational program which ranged from 3.8 to 8.0 pci/g (dry).

Gross beta activity in samples of shoreline sediments collected from all locations ranged from 5.3 to 11.9 pCi/g (dry) during 1990. The majority of this activity was attributed to naturally occurring K-40. These values are comparable with the activity detected in the preoperational program which ranged from 7.0 to 17.2 pCi/g (dry).

Bottom Sediments Samples of bottom sediments are collected from Clinton Lake at six locations and Lake Shelbyville at one location. Radiological analyaes of bottom sediments primarily provide information about the amount of radionuclides available to' predators who !

feed on the organisms found in bottom sediments.

Samples are collected semiannually and analyzed for gross beta, gross alpha, Sr-90 and gamma isotopic activities.

A new bottom sediment sampling location was added to the Clinton Power Station Radiological Environmental Monitoring Program in October 1990.

This location is at 3.5 miles in the southwest sector on the lake side of the Clinton Lake damn.

This location was added since it is considered to l be a excellent location for the accumulation of radioactivity from Clinton Power Station.

Bottom sediment samples are dried' prior to analysis and the results are reported in pCi/g dry weight. Naturally occurring radioisotopes, such as K-40 and Pb-212, were,present in all'1990 control and indicator sample locations.

Fission product, Cs-137, was detected in samples from indicator and control locations. Strontium-90, also a fission product, was detected in indicator samples and in one control sample.

Cs-137 0.008 to 1.39 0.058 to 0.45 l 55 l l

The presence of these fission products is attributed to previous nuclear weapons testing and atmospheric fallout from the accident at chernobyl.

Gross alpha activity in samples of bottom sediments collected from both lakes ranged from 5.8 to 14.5 pCi/g (dry) during 1990. This activity was attributed to naturally occurring radium isotopes and decay products present-in '

soil. The preoperational gross alpha activity ranged from 4.4 to 14.7 pCi/g (dry).

Gross beta activity in samples of bottom sediments collected from both lakes ranged from 6.7 to 33.8 -

pCi/g (dry) during 1990. The majority of this activity was attributed to naturally occurring K-

40. The preoperational gross beta activity ranged .

from 8.3 to 27.7 pCi/g (dry).-

Two additional bottom sediment-samples were collected in 1990 from different locations in the area of the Ultimate Heat Sink in Clinton Lake.  !

These samples were drawn during dredging i Samples operations of the Ultimate Heat Sink.

were analyzed for gross beta, gross alpha, Sr-90 and gamma isotopic activities. Results of these .

analyses were consistent with bottom sediment samples obtained from the normal bottom sediment  !

sample locations. No activity detected was -

attributed to the operation of Clinton Power Station.

Acuatic Vecetation (Periphyton)

Samples of periphyton are collected from five locations in Clinton Lake'and one location in Lake Shelbyville. Periphyton-(attached algae) are collected from the submerged-surface ofz the permanently anchored buoys. Periphyton absorb trace elements:and radionuclides directly from ,

water, often c6ncentrating them to levels much i 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 division usually occurs _once every one or'two days and, as a result,- nalf 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 56 m________ ___

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 samples showed the following concentrations of naturally occurring radioisotopes:

Preoperational Range 1990 Range (oC1/a wet) (DCi/a weti' Be-7 0.38 to 1.07 0.38 to 2.55 K-40 0.74 to 6.82 1.00 to 5.18 one fission product, Cs-137, was detected in several periphyton samples. Concentrations for

.Cs-137 in 1990 ranged from 0.030 to 0.120 pCi/g (wet). Preoperational results for Cs-137 showed concentrations ranging-from 0.042 to 0.15 pCi/g '

(wet). The prosence of Cs-137 is attributed to previous nuclear weapons testing and atmospheric -

fallout from the accident at Chernobyl.

One activation product, co-60, was detected at a downstream sample location in 1990. One sample result at CL-19 showed Co-60 at a concentration of 0.20 pCi/g (wet). This activity is attributed to liquid radioactive effluent discharges from Clinton Power Station. The presence of.Co-60 in Clinton Lake periphyton poses no-significant exposure pathway to man since the fish species (intermediate in the food chain to man) do not contain measurable amounts of this nuclide.

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. Periphyton provides good qualitative information, however, there are

J quantitative limitations. 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 i effluents to aquatic systems. It enables the Radiological Environmental Monitoring Program to determine the relative presence of radioactivity before it becomes a problem.

57

E. Terrestrial Monitorina In addition to the direct radiation, radionuclides present in the atmosphere expose individuals when these radionuclides deposit on surfaces (such as plants and soil) and are subsequently ingested directly by man or indirectly by consumption of 1 animal products such as meat and milk. To monitor-this food pathway, control and indicator samples of green leafy vegetables, grass, milk (control-only) and meat (indicator only) are analyzed.

Surface soil samples are collected and analyzed at three vear intervals (triennially) to monitor the potential buildup of atmospherically deposited radionuclides.

Surface vegetation samples are collected from a number of locations for the purpose of monitoring the potential buildup of atmospherically deposited radionuclides. Because the-radionuclides of interest, with respect to the Clinton Power Station operations, are also_present in the environment as a result of several decades of worldwide fallout or because they are naturally occurring, the presence of these radionuclides is expected in all of the samples collected. 1 l

The possible contributions of radionuclides from the operation of the Clinton Power Station are assessed by comparing the results of samples collected in prevalent downwind locations (north to northeast of the plant) with control samples-and samples collected in locawiens generally _.

upwind of the plant. In addition, the results of samples collected during 1990 were compared with the results of samples collected.during the preoperational program.

In addition to naturally eccurring radioisotopes, Sr-90 and Cs-137 were found in a-number of 1990 samples. However, the concentrations.of radionuclides in samples _collecteo near the 4 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 operation of Clinton Power Station had no measurable contribution to-the radioactive concentration of the terrestrial environment.

58

Milk There is no known commercial production of milx for human consumption within a five-mile radius of the Clinton Power Station. Milk samples are collected from a dairy located about 14 miles west 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 1990 samples with a range of 1120 to 1310 poi /l for K-40 and 1.0 to 3.3 pCi/l for Sr-90.

-Preoperational activity of K-40 in milk ranged from 706 to 1375 pCi/1. Strontium-90 (Sr-90) 3 analysis in milk was added'to the REMP in October of 1987. These results ranged from 2.3 to 2.5 pCi/1. I-131 was not detected in any milk sample obtained during 1990. Figure 10 presents the Sr-90 results graphically,

Grass In addition to milk samples, grass samples are collected at four indicator locations and at one control location. These samples are collected twice a month during May through October and once a month during November through April. Theso samples are analyzed for gamma isotopic activity including I-131.

The results of the analysos showed naturally occurring Bo-7 and K-40 in all 1990 samples. Ono control sample and four indicator samples showed the presence of Cs-137 in 1990.

Veaetables The Clinton Power Station obtains samples of cabbage, lettuce and swiss chard from two indicator locations and at one control location.

The indicator locations are located in the' sectors-with the highest potential for surface deposition .

and the control location is in a sector and at a i distance which is considered to be unaffected by plant operations. Samples are collected once a l month during the growing season (June through September) and analyzed for gross beta and gamma-isotopic activities including I-131.

The results of the gamma isotopic analysis.showed only naturally occurring K-40 and Be-7. K-40 was found in all 1990 samples and Be-7 was found in thirteen samples. 1

any radioisotopes related to the operation of the Clinton Power Station. Both indicator and control locations were sampled during 1990. These samples were analyzed for naturally occurring and man-made radioactive isotopes. Average tritium and gross beta concentrations in surface, drinking and well water are presented in Table 9 and Table 10.

Drinkina Water The Clinton Power Station domestic water system is the only known direct user of water from Clinton Lake for human consumption. A composite water ,

sampler located in the Service Building collects a j small, fixed volume sample at hourly intervals.

The sampler discharges each sample into a common sample collection bottle. Therefore, the monthly sample analyzed by the contracted laboratory service is a composite of the individual samples i collected throughout the month. The monthly ,

composite sample is analyzed for gross alpha, 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 quarterly composite sample i is analyzed for tritium.

Gross alpha activity was detected in one sample at 0.5 pCi/1. This autivity is attributed to naturally occurring radioisotopes, such as U-238 and Ra-226, suspended as fine sediment particles in water.

Gross beta activity ranged from 1.5 to 2.7 pCi/1.

These levels are attributed to very fine particles of sediment containing K-40 which are not removed during the chlorination and filtration process.

Monthly drinking water gross beta concentrations are presented in Figure 11.

Specific gamma-emitting radioisotopes were all below the lower limits of detection. Specific ,

searches were made for activated corrosion

  • l products (manganese-54, iron-59, cobalt-58, i cobalt-60 and zinc-65) and fission products (niobium-95, zirconium-95, cesium-134, cesium-137, barium-140 and lanthanum-140). l The results of all analyses for tritium were less I than the lower limit of detection.

These results show no measurable effects on drinking water resulting from operation of the Clinton. Power ^ Station during 1990.

2 Surface Water Composite water samplers are installed in three locations to H iple surface water from Clinton Lake. These seaplers collect a smc11-volume of water at regular intervals and discharge it to a e large sample collection bottle. These bottles are

  • collected monthly. One of the composite samplers is located upstream from Clinton power Station and is unaffected by plant liquid releases downstream.

The two other composite samplers are positioned at the locations most likely to be affected by 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 fiume). Monthly grab samples are collected from two indicator locations and one control location on Clinton Lake. :one additional indicator sample is obtained from the Clinton .

Power Station lower settling pond.

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 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 lower settling pond, the intake structure water samples and the upstream composite water-samples, and quarterly

- from composites of monthly. samples at the other ,

locations.

The 1990 results of the gross beta analyses. ranged- ,

from 1.6 to 4.6 pCi/l at the indicator locations and 1.1 to 4.5 pCi/1 at the control location.

Preoperational gross beta activity ranged from 1.1 to 7.6 pCi/1. These results are attributed 1to ,

weapons testing increased the pre-1960 levels of tritium (6-24 pci/1) by a factor of approximately <

fifty (300-1200 pCi/1). Since the level of tritium reported in the one positive sample fell in the low end of the existing, non-reactor-related, natural inventory of tritium, it is considered this positive result is not associated with operation of the Clinton Power Station.

Specific gamma-emitting radioisotopes were all below the lower limits of detection. Specific searches were made for activated corrosion products (manganese-54, iron-59, cobalt-58, cobalt-60 and zinc-65) and fission products (niobium-95, zirconium-95, cesium-134,-casium-137,.

barium-140 and lanthanum-140). No I-131 was detected in any surface water sample during 1990.

Gross alpha activity was-detected in approximately half the surface water samples analyzed for gross alpha. The 1990 results ranged from 0.6 to 1.7 a pCi/1. Preoperational gross alpha activity ranged j from 1.3 to 1.9-pC1/1. These results were attributed to naturally occurring radioisotopes, such as U-238'and Ra-226, suspended as fine sediment particles in water.

G. Quality Assuranco Proaram To establish confidence that data developed and reported are accurate and precise, all REMP activities are 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 crosscheck program.

  • An annual audit of the analysis laboratory functions and facilities.

Biennial review of the Clinton Power Station procedures specifying sampling techniques.

Duplicate analysis of every tenth sample assayed (not including TLDs). This requiremont is to check laboratory precision.

The routine counting of quality control samples. Approximately ton 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.

Tolodyno Isotopes Midwest Laboratory (TIML) participates in the Environmental Protection Agency crosschock program. The TIML participant code in the crosscheck program is CA.

Participation in this program provides assuranco that the laboratory is capable of mooting widely-accepted criteria for radioactivity analysis.

TIML correctly analyzed 96% of the U.S. EPA crosschock samples and 97% of in-house spiked samples. Those results indicate that TIML is capable of routinely performing high quality analysis on environmental samples.

Results of the 1990 crosschock program and other in-house quality programs are shown in Appendix E.

H. Chances to the REMP Durina 1990 occasionally changes to the Radiological Environmental Monitoring Program are necessary in order to improve the monitoring of the environmental expecure pathways. These changes may result from items identified during the performance of the Annual Land Use Census, revised or new regulatory requirements, Quality Assurance audits or supplemental periodic and long-term sampling and analyses.

During 1990, one air sample station was added due to a Quality Assurance audit finding. There were no changes necessary due to the Annual Land Use Census or regulatory requirements.

A soil sampling location and a lake bottom sediment sampling location were added as improvements by the Radiological Environmental staff in 1990.

Changes that were made and the reasons for the changes are listed in Table 11.

TABLE 11  !

CHANGES TO THE REMP DURING 1990 i

1. February, 1990 Collection of airborne particulates and radiciodines was initiated at CL-15. An environmental TLD location was also established at this location. CL-15 is located ,

0.9 miles in the North sector and was established to satisfy CPS Offsite Dose Calculation Manual requirements which require that airborne particulates_and-radiolodine samples be collected in different sectors, close to. .

the CPS site boundary, with I the highest calculated annual average ground-level D/Q's.

Historically, the North sector has one of the h3ghest annual average ground-level D/Q's.

2. March, 1990 A soil sampling location CL-16 located 0.6 miles East-southeast was established.

CL-16 was established at this location because this is where CPS Sewage Treatment Plant waste sludge is land applied. i Sampling will commence in the I summer of 1991.

3. October, 1990 Collection of bottom sediments was initiated at CL-17. CL-17 i is located 3.5 miles Southwest i and was established to monitor- 1 the acco.mulation of radionuclides in bottom sediments in Clinton Lake on the lake side of the dam.

ANNUAL LAND USE CENSUS

1 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 modifications to the REMP are made, if required, by evaluation of the land use census.

The land use census is performed to identify within a distance of 5 miles, the locations in each of the 16 l meteorological sectors of the nearest milk animals, the l nearest residence and the nearest garden of greater than 500 square feet producing broad leaf vegetation.

Also, the census shall identify within a distance of 3 miles, 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 1990 Land Use Census was conducted during the growing season from July 16, 1990, through September 26, 1990, satisfying the CPS offsite Dose Calculation Manual requirements. Over 90 residences were surveyed by either mail survey, telephone follow-up, or direct contact. Data for this report was obtained using the following meanst Performing door-to-door solicitation of one-half of the residences / land owners identified in the 1989 Annual Land Use Census and the 1989 plat of DeWitt County.

i Soliciting the remaining half of the residences / land owners identified in the 1989 Annual Land Use Census by mail survey and telephone follow-up.

Driving along all roads within a five-mile radius-and performing door-to-door solicitation of residences / land owners not identified by the 1989 report.

Contacting several state and local agencies.

The results of the 1990 Annual Land Use Census were examined to ensure that the REMP will provide ,

representative measurements of radiation and ,

radioactive materials in those exposure pathways and 1 for those radionuclides that lead to the highest potential radiation exposures to the general public resulting from the operation of the Clinton Power Station._ Table 12 provides the nearest residence, garden and livestock / dairy animal in each of the 16-meteorological sectors within a 5-mile radius of the Clinton Power Station. Figure 14 graphically shows the information' listed in Table 12.

83

l Summary of Changes Identified in 1990 Annual Land Use census Nearest Residence Four changes were identified for the nearest residence.

The changes were attributed to new residence and ownership change. Changes in nearest residence are shown below:

NNE Sector - Change in residence ownership at 0.9 l miles.

SSE Sector - Change in residence ownership at 1.7 miles.

SSW Sector - Change in residence ownership at 3.0  !

miles.

WNW Sector - Change in residence ownership at 1.6 miles.

Nearest Garden A total of 60 gardens were identified in the 16 sectors ,

within a 5-mile radius of Clinton Power Station of l which 39 produced broad leaf vegetation (spinach, i lettuce, cabbage and chard). In most cases, tomatoes, sweet corn and beans were grown in gardens identified.

Changes in census locations for the nearest garden were identified in 9 of the 16 sectors and are shown below:

V. METEOBOLOGICAL CHARACTERISTICS A. Descriotion The climate of central Illinois is typical of the Midwest, with cold winters, warm summers and

> frequent short-period fluctuations in temperature, humidity, cloudiness and wind direction. The ,

variability in central Illinois climate is due to I its location in a confluence zone (particularly during the cooler months) 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 Rockiest Pacific air which originates in.the eastern: North Pacific Oceant and continental polar and 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 ar: determined by the movement of storm systems which commonly follow paths along a major confluence: zone between air masses. The confluence zone is usually oriented .

from southwest to northeast chrough the region and normally shifts.in latitude;during this period, l ranging in position-from the central. states to the United States - Canadian border. The average frequency of passage of storm systems along this zone is about once every-5 to 8-days. These storm-systems are most frequent during the winter and-spring months, causing a-maximum of cloudiness

  • during these seasons. Winter.is-characterized by alternating periods of' steady _ precipitation and_

periodsLof clear,-crisp;and cold weather.- ,

Springtime-precipitation is'primarily showeryLin 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, result in this season's thunderstorms and 1

on occasion, are the source of hall, damaging winds and tornados. Although storm systems also occur during the fall months, the frequency of occurrence during these months is less than that of the winter or spring months. Periods of dry weather characterize the fall season which ends rather abruptly with increasing storminess that usually begins in November. j In contrast, weather during the summer months is.

characterized by weaker storm systems which tend to pass to the north of Illinois. A major confluence zone is not present in this region,-and the-region's weather is characterized by much-sunshine interspersed with thunderstorms. Showers and thunderstorms-are usually of the hir mass type, although occasional outbreaks of cold air-bring precipitation and weather. typical of that associated with the fronts and storm systems of l the spring months. l i

When southeasterly and easterly winds are present:

in central Illinois, they usually bring mild and-wet weather. . Southerly winds are warm and showery, westerly winds are dry.with moderate temperatures, and winds from the northwest and  ;

north are cool and dry. i The prevailing wind is sontherly at the clinton Power Station. The frequency-of winds from othor-directions is relatively well distributed.' The monthly average wind speed is lowest during late j summer and. highest during late winter and.early spring.

Table 13 presents a' summary of climatological data at meteorological stations surrounding the clinton Power Station site from.1937 through-1976.: The annual average temperature at the clintoniPower.

Station is about 52*F. Monthly average terparatures in the1 region range.from the middic twenties in January to the middle seventiesfin July.. Maximum temperatures in the clinton Power Station region equal or. exceed 90'F on'an. average q between 17 and 28 times'per year. Minimum 1 temperatures in this region are less'than or equal.

year at Peoria and 18 times per year.at t Springfield. Heavy fog occurs most frequently during the winter' months. t Annual precipitation in the clinton Power Station ,

area averages about 35 inches per year. On the '

average, about 45% of the annual precipitation in the-clinton Power Station region occurs in the- 1 5-month period from April through August. i However, in this region no month averages-less than 4% of the annual total. Monthly; precipitation totals have ranged from 0.03 to -

13.09 inches (Peoria).. Snowfall commonly-occurs

- from November through March, with an annual average of 23.4 inches at Peoria, and.22.3 inches t at Springfield.

The monthly maximum snowfall of 18.9 inches'at Peoria, and 22.7 inches at Springfield, occurred .

, in December 1973.- The 24-hour maximum snowfall, i which also occurred in December.1973, was 10.2

The onsite meteorological tower obtains information that is valuable in determining plume dispersion by providing differential temperature, wind speed and direction. Table 14 summarizes the seven stability classes, with unstable conditions dispersing a plume more than stable conditions.

Table 15 compiles the total hours for different wind speeds for each stability class during 1990, at 10 meters and 60 meters. Figures 15 and 16 are wind rose graphs which show predominant wind direction at 10 and 60 meters for the Clinton Power Station.

Indicated elapsed time was used for' sample calculation.

  • Grass samples are normally anal.yzed wet. During winter months and drought conditions, the grass will dry up and die._ Dry, dead grass has a moisture content much lower than that of fresh green grass. Analysis of dry -

dead grass may be biased.

GLOSSARY activation - the process in which stable atoms become radioactive atoms by absorbing neutrons. ALARA - acronym for "As Low As Reasonably Achievable" which . applies to many facets of nuclear power, i.e., radiation exposure for personnel kept low, minimizes number / activity of offluent discharges. alpha particle - a charged particle emitted from the nucleus of an atom having a mass and charge equal in magnitude of a helium nucleus (2 proton and 2 neutrons). atom - the smallest component of an element having all the properties of an element. Comprised of protons, neutrons and electrons such that the number of protons determines the elem9nt. background radiation - source of radiation that mankind has no control of, such as cosmic (from the sun) and terrestrial (naturally occurring radioactive elements) . beta particle - a charged particle equivalent to an electron if negative or a positron if positive, originating near the nucleus of an atom during radioactive decay or fission. control location - a sample collection location considered to be far enough away from Clinton Power Station so as not to be affected by station operations. cosmic radiation - penetrating ionizing radiation originating in outer space. curie (ci) - the unit of radioactivity equal to 2.2 trillion disintegrations per minute, i dead water - water that contains no tritium, dose - a quantity (total or accumulated) of ionizing radiation received. dose equivalent - a quantity used in radiation protection which expresses all radiations on a common scale-for calculating the effective absorbed doso (the unit of dose equivalent is the rem), ecology - a branch of biology dealing with the relations between organisms and their environment. l 144 ,

i i I i i i i electromagnetic radiation - a travelling wave' motion j resulting from changing electric or magnetic fields. l Familiar sources of electromagnetic radiation rango from x-rays (and gamma rays) of short wavelength, through the ultraviolet, visible and infrared regions, to radar and ! radiowaves of relatively long wavelength. All

electromagnetic radiation travels in a vacuum at the speed of light.

element - one of 103 known chemical substances that cannot be broken down further without changing its chemical , properties. environment - the aggreg'tea of surrounding things, conditions, or influences, t exposure - a measure of the ionization produced in air by x-ray or gamma radiation. Acute exposure is generally accepted to be largo exposure received over a short period of time. chronic exposure is exposure roccived over a long , 4 period of timo, fission - process by which an atomic nucleus splits into two smaller nucloi and releases neutrons and energy. fission products - the nuclei formed as part.of the fissioning of an atomic nuclous. gamma rays - high energy, short wavelength electromagnetic radiation omitted from the-nucleus. half-life - the time required for half of a given amount of a radionuclide to decay. indicator location - a sample collection strategically placed to monitor dose rate or radioactive material that may-be the result of clinton Power Station operations. ionization - the process by which a neutral atom or molecule acquires a positive or negative charge. irradiation - exposure to radiation.. Lower Limits of Detection-(LLD) - the smallest amount of sample activity that will give a net.-count for which thero , is a confidence at a predetermined level that the--activity is present. a microcurie - one millionth of a curie and represents 2.2 million decays per minute. neutron - one of the three basic parts of an atom which has: no charge and is normally found in the nucleus (center) of an atom. 145  ! l L-.,_-_.,._;.__.. _ . . . - .- _ _ _ , _ , _ . _ _ _ _ - . . . , . . a, _~ . - - - _ _ _ . , _ _ . _ . . - . . _ . . . _

1 nucleus - the conter of an atom containing protons and neutrons, that determines the atomic weight and contributes to the not positive charge of an atom, nuclei (plural) nuclides - atoms which all have the same atomic number and mass number. periphyton - water plant life (i.e., algae). radiation - the process by which energy is emitted from a nucleus as particles (alpha, beta, neutron) or waves (gamma). radionuolide - a radioactive species of an atom . characterized by the constitution of its nucleus. The nuclear constitution is specified by the-number of protons, number of neutrons, and energy centent. rem - the unit of dose of any ionizing radiation that produces the same biological effects as a unit of absorbed dose of ordinary X-rays. Acronym-for Roentgen Equivalent Man. roentgen - a measure of ionization produced in air by x-ray or gamma radiation. statistics - the science that deals with the. collection, classification, analysis and interpretation of numerical data by use of mathematical theories of probabilities. terrestrial radiation - source of radiation pertaining to the ground (Earth's crust). wind rose - a graphic representation indicating from'which direction and speed the wind blew. x-rays - high energy, short wavelength' electromagnetic radiation, emitted from the electron shells of an atom. i i 146- _-_________i__.___i___.___.____..__.__.._______.
