SUMMARY

This report describes the Annual Radiological Environmental Monitoring Program (REMP) conducted near the Clinton Power Station (CPS) during the 1997 calendar year. The REMP was performed as required by the CPS Operating License issued  ; by the United States Nuclear Regulatory Commission. The objective of the REMP is to assess any radiological impact upon the surrounding environment due to the operation of the Clinton Power Station. During 1997, over 1,700 environmental samples were collected. These samples represented direct radiation; atmospheric, terrestrial, and aquatic environments; and Clinton Lake surface water and public drinking water supplies. About 2200 analyses were performed on these environrrantal samples. Results of the analyses showed 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. Radiological environmental measurements taken during 1997 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 control locations (sample locations not affected by station operations) and preoperational results. There were no radioactive liquid discharges during 1997. Releases of gaseous radioactive materials were accurately measured in plant effluents. There were no gaseous releases that came close to approaching the limits specified in the CPS Offsite Dose Calculation Manual (ODCM). The highest calculated offsite dose received by a member of the public due to the release of gaseous materials from Clinton Power Station was 0.007 mrem. All compansons among operational data and preoperational data showed that the operation of Clinton Power Station had no measurable effect upon the environment in 1997. l l-1 i I

L I I II. INTRODUCTION The Radiological Environmental Monitoring Program (REMP) at Clinton Power Station (CPS) is ( designed to monitor the environment surrounding the plant for any radioactive material that may be released by CPS as a result ofplant operations. The ( primary concern is what impact, if any, the radioactive materials released from CPS have on the generalpublic. This report is prepared 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. CT! 1RACTERISTICS 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 f           (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 u ay 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 / H-1

Il1 I produced-artificially in accelerators and nuclear reactors (e.g., radioactive iodine, cesium and cobalt). NATURALLY OCCURRING MAN-MADE RADIONUCLIDES RAD 70NUCLIDES Uranium Iodine Thorium Cesium Carbon Cobalt Potassium Strontium Lead Barium The activity of a radioactive source is the average number of nuclear disintegrations (decay) of the source per unit of time. The unit of activity is called the curie. A one curie radioactive source undergoes 2.2 trillion diqintegrations per minute, but ip 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. 1 curie (Ci) = 2,220,000,000,000 disintegrations / minute I 1 millicurie (mci) = 2,220,000,000 disintegrationsiminute g 1 microcurie ( Cl) = 2,220,000 disintegrations / minute 3 1 nanocurie (nCi) = 2,220 disintegrations / minute 1 picoeurie (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 j 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 yearc requires about 462,400 grams to obtain an activity of one curie. But iodine-131 (I-131) with a half-life of 8.04 days only requires about 0.000008 grams to produce an activity of one curie. 1 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 I 11 - 2 1 l I

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 are of this form. l When radioactive elements enter the body through 3 in.ialation or ingestion, their distribution may not be uniform. I TARGET TISSUE NUCLIDE Bone Strontium-90 Kidney Uranium-235 Thyroid Iodine-131 1 Muscle and Liver Tissue Cesium-137 Gastrointestinal Tract Cobalt-60 For example, radiciodine selectively concentrates in the thyroid gland, whereas radiocesium collects in muscle and liver tissue, and radiostrontium collects in mineralized bone. The total dose to organs by a given radionuclide is also influenced by the quantity and the duration of time that the radionuclide remains in the body. Owing to radioactive decay and human retabolism factors, some radionuclides stay in the body for very short times while others remain for years. The amount of radiation dose that an individual receives is expressed in rem. Since human exposure to radiation l usually involves very small exposures, the millirem I (mrem) is the unit most commonly used. One millirem is one thousandth of a rem. I 1 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. 11 - 3

I 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 B radioactive. N Natural Radionuclides In The Earth's Crust I M wu e : - 4 L ,F-4, Radium-226 (Ra-226) U:w itn __3 :U-JL2 Radon-222 (Rn-222) Inc rit , .?' iTP- 'M 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. l These radionuclides are introduced into the water, soil 5 and air by such natural processes as volcanic activity, weathering, erosion and radioactive decay. Some of the naturally occurring radionuclides, such as raden, 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 3 radioactive materials called " radon daughters". These 5 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 3 and become trapped in a small air volume indoors. Thus, indoor radon concentrations are usually higher than 5 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, 3 I Radon daughters emit high energy alpha radiation dose to g the lung lining. Table 1 shows the average annual effective dose due tc radon. About three hundred cormic rays originating from outer space pass through each person every second. n.4 I l i I

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) The 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 contribut~ing 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 erproximately three hundred mrem per year from natural sources. In some areas of the cou' cry, the dose from natural radiation is significant.. y 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. 11 - 5

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 iJ associated fuel cycle.

" Fallout" commonly refers to the radioactive debris that settles to the surface of the earth following the detonation of nuclear weapons.           Fallout is dispersed throughout the environment but can be washed down to the Earth's surface by rain or snow.

Radionuclides Found in Fallout Iodine-131 (I-131) Strontium-90 (Sr-90) Strontium-89 (Sr-89) Cesium-137 (Cs-137) There are approximately two hundred radionuclides produced in the nuclear weapon detonation process; a number of these are detected in fallout. The radionuclides found in fallout that produce most of the fallout radiation exposures to man are iodine-131, strontium-89, strontium-90, and cesium-137. Il - 9

I C. DESCRIPTION OF THE CLINTON POWER STATION h The Clinton Power Station is located in Harp Township, DeWitt County, Illinois. It is .pproximately six miles east of Clinton, Illinois. The station, its V-shaped cooling lake, and the g surrounding Illinois Power Company-owned land encloses W 14,182 acres. This includes the 4,895-acre, man-made cooling lake and about 90 acres of privately owned g property. The plant is sited on approximately 150 acres on the northern arm of the lake. The cooling water g' 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 E acres lie in Wilson, Rutledge, DeWitt, Creek, Nixon and 5 Santa Anna Townships. The cooling lake was formed by constructing an earthen 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 adj acent to the lake are used for public recreation activities, including swimming, boating, water-skiing, hunting and fishing. Recreational E facilities exist at Clinton Lake and accommodate up to B 11,460 people per day during peak usage periods. The outflow from Clinton Lake falls into Salt Creek and g flows in a westerly direction for about 56 miles before g 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 3 Agency Public Water Service. Although some farms in the E 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 11 - 1 0 I

about 22 miles south southwest) and Springfield (located aoout 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 l Clinton Power Station is used for farming. The j 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 the process called " fission". In fission, the l uranium atom absorbs a neutron and splits to produce fission products, heat, radiation atA free neutrons. l The free neutrons travel in the reactor core and further absorption of neutrons by uranium permits the fission i process to continue. As the fission process continues, , more fission products, radiation, heat and neutrons are ' produced and a sustained reaction occurs. The heat produced is extracted from the fuel to produce steam that drives a turbine generator to produce electricity. 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 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". Fission Products Activation Products l Cesium-134 (Cs-134) Cobalt-60 (Co-60) Cesium-137 (Cs-137) Manganese-54 (Mn-54) Ruthenium-106 (Ru-106) Iron-55 ( Fe- 5 5 ) Barium-140 (Ba-140) Iron-59 (Fe-59) Cerium-144 (Ce-144) Zinc-65 ( 2n- 6 5 ) Strontium-89 (Sr-90) Tritium (H-3) 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 l ceramic pellets that are loaded into sealed fuel rods. l ll - 11

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 j et 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 H-15

' I defense against the uncontrolled release of radioactive materials to the environment. The massive concrete l walls also serve to absorb much of the radiation emitted a during reactor operation or from radioactive materials I created during reactor operations. F. SOURCES OF RADIOACTIVE EFFLUENTS In an operating nuclear power plant, most of the fission 3 products are retained within the fuel and fuel cladding. 3 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 E coolant. Trace quantities of the corrosion products 5 from component and structural surfaces that have been activated, also get into the primary coolant. Many soluble fission and activation products such as radioactive iodines, strontiums, cobalts and cesiums are removed by demineralizers in the water 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 g bromine, are carried from the reactor pressure vessel to 3 the condenser with the steam. The steam jet air ejectors or the condenser vacuum pump remove the gases from the condenser and transfer them to the off-gas treatment system. In the off-gas treatment system, the gases are held up by adsorption on specially treated charcoal beds to allow radioactive gases to decay before they are released through the main ventilation exhaust stack. 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 E for reuse. Processed primary coolant water that does 5 not meet chemical specifications for reuse may also become waste water. These represent the principal a sources of liquid effluents. g E ll - 16 I

G. RADIOACTIVE WASTE PROCESSING In a normal operating nuclear power plant, radioactive liquid and gaseous wastes are collected, stored and processed through treatment systems to remove or reduce most of the radioactivity (excluding tritium) prior to reuse within the plant or discharge to the environment. i 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 ~ ~ Reasonably Achievable (ALARA). The liquid waste tr3atment systems consist of filters, demineralizers and evaporators. Liquid wastes are routed through the waste evaporators to be degassed and volume I distilled thereby reducing concentrating their radioactivity. their The distillates further treated through demineralizers and filters and and are transferred to the waste evaporator condensate storage I tanks. Liquid wastes are processed through appropriate portions of the liquid waste treatment the system to provide assurance that the releases of I radioactive materials in liquid effluents will be kept ALARA. 3 Liquid wastes are discharged into the plant cooling l 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 g Manual requires that liquid effluents not contain a l 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 I flow. The additional dilution that occurs in the cooling water canal reduces the concentrations of radioisotopes to between 1/73 (for minimum flow) and I 1/1890 (for maximum flow) of their original value before the water enters Clinton Lake. The concentrated radioactive solids captured in the j liquid waste treatment system are processed and stored l on-site or shipped off-site for disposal at licensed low-level waste disposal facilities. l The gaseous effluents from the main condenser are held up in the off-gas charcoal beds for at least 46 hours. ll - 17

I This provides time for the decay of most of the g radionuclides present since most have a half-life of g 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.

IH. RADIOLOGICAL ENV1RONMENTAL 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 (CFR) Title 10, Section 20.1501 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 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 St3 tion and fluctuations in radioactivity levels which may occur 0 evaluation of the measurements to determine the impact of Clinton Power Station 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 the requirements to trend and assess radiation exposure rates and radioactivity concentrations in the environment that may contribute to radiation exposure to the public. The program consists of two phases, preoperational (preop) and operational. lil-1

l ' The preoperational portion of the program was initiated in May, 1980 and was completed on February 27, 1987 to establish the baseline for the local Assessment of the operational impact of the radiation 3 wavironment. 3 Clinton Power Station on the radiation environment is l based on data collected since the beginning of reactor g operation. The operational phase implements confirmatory measurements to verify that the in-station controls for g the release of radioactive material are functioning as designed. l Illinois Power Company maintains a contract with Teledyne l Isotopes Midwest Laboratory (TIML) dab Teledyne Brown E

Engineering Environmental Services Midwest Laboratory g (TBEESML), 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. E Analytical results are reported monthly to company W 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. Figure 3 shows the bacic pathways of gaseous and liquid radioactive effluents to an individual. The "important pathways" selected are based primarily on how radionuclides move through the environment and eventually 3 l expose individuals, environment. as well as man's use of the The scope of the program includes the 3 monitoring of five environmental compartments: 1 direct radiation l atmospheric aquatic E terrestrial environments W 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 and at locations which are - expected to manifest station effects, if any exists. Control locations are located at least ten miles from the plant, far enough to be unaffected by plant operations. These control samples provide a basis by which to evaluate g fluctuations in radioactivity at indicator locations in g relation to natural phenomena and fallout. An increase in dose rate or radioactive material concentration at an indicator location may be due to plant operations. 111- 2 I I

l Sampling locations were established by considering site meteorology, population distribution, site hydrology, and land use characteristics of the local area. These locations were selected primarily on the basis of where the highest predicted environmental concentrations would occur. Locations of sampling stations are shown on maps in i Figures 4 through 7. Table 2 provides a list of the sample codes for each sample medium. Table 3 provides information on sample location, media sampled at each location, and a brief description of each location where samples are taken.

B. Direct Radiation Monitoring 4 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 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. l TLD measurements register the gamma ray exposure in milliroentgen (mR). For reporting purposes mR is 1 numerically equivalent to mrem. Consequently the terms l are used interchangeably. ' A total of 342 TLD measurements were made in 1997. The average quarterly dose at indicator locations was 16.8 4 mrem. These quarterly measurements ranged from 11.8 to 21.1 mrem. At control locations the average quarterly dose was 17.1 mrem. These quarterly control measurements ranged from 14.0 to 19.5 mrem. Figure 8 compares the 1997 quarterly TLD results with preoperational TLD quarterly averages. Average doses (i2 standard deviations), broken down by calendar quarter, are shown in Table 4 for both indicator and control locations. lll-23

From these observations, no increase gamma radiation levels resulted in environmental from operation of I Clinton Power Station. the C. Atmospheric Monitoring 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 I monitors this pathway. There are nine Power Station 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 of the plant in an area which is likely to be independent 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 of station radioactivity could be identified as a result operations. 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 a filter and charcoal cartridge to 111- 2 7

I 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 E volume is calculated based on the amount of time the air 5 sampler ran and its flow rate. The air sampling equipment is maintained and calibrated by the Clinton Power Station a personnel using reference standards traceable to the g 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 3 particulate sampling is to measure airborne radioactivity 'E released from the plant, the counting of short-lived daughters produced by the decay of 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 gross E beta activity. 5 Results of the gross beta airborne particulate analyses g provided comparisons between indicator and control g l locations for the year, as well as comparisons between locations in relation to spatial and temporal differences. l The calculated annual average was 0.022 pCi/m3 for all indicator locations and 0.022 pCi/m3 for the control location. These results are consistent with the j preoperational averages for both indicator and control i locations which were 0.027 pCi/m 3, l The location with the highest calculated annual average was the control station CL-11 which is located 16 miles south of the Clinton Power Station. This location had an average concentration of 0.023 pCi/m3 Individual location averages for the year are presented in Table 5. Minor fluctuations in the gross beta concentrations were noted throughout the year. The general trend for average g weekly gross beta concentrations in the indicator g 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 l l 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 6.

All gross beta concentrations for the year were within g normal background levels and no increases were noted as a E result of the operation of the Clinton Power Station. lll-28 I I-

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

D. Acuatic Monitorina 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 j on successive trips through the plant. This water travels l 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. r l Clinton Lake constitutes the primary environmental l 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 l related to operation of the Clinton Power Station. These l samples are analyzed for naturally occurring and man-made l radioactive materials. Both indicator and control locations were sampled. Indicator samples were taken from various locations on Clinton Lake and the control samples l 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. l l Fish l l 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 sport fishermen. 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. These samples are collected semiannually and analyzed by gamma spectroscopy. t The results of gamma isotopic analysis on the fish samples showed the presence of naturally occurring K-40 in all samples ranging from 2.28 to 3.18 pCi/g (wet) .

     'Preoperational K-40 concentrations ranged from 1.71 to 4.61 pCi/g (wet). All other analytical results were less lil-33

than the lower limit of detection (LLD) for each radionuclide. Shoreline Sediments Samples of shoreline sediments are collected at six locations from Clinton Lake and at one location from Lake 3 Shelbyville. Radiological analyses of shoreline sediments g provide information on the potential shoreline exposure to humans and for determining long-term trends and accumulation of long-lived radionuclides in the environment. Samples are collected semiannually and - analyzed for gross beta, groes alpha, Sr-90 and gamma isotopic activities. Shoreline sediment samples are dried prior to analysis and the results are reported in pCi/g dry weight. Naturally g occurring radioisotopes, such as K-40, Be-7, Ra-226 and g Pb-210, were present in samples taken at both indicator and control locations. There was one fission product, Cs-137 detected at one indicator location. The activity- h W detected was not substantially different from that measured during the preoperational program. The presence of these fission products is attributed to previous nuclear weapons testing and atmospheric fallout from the accident at chernobyl.

  • Only one positive result was identifed.

Gross alpha activity was detected at one indicator I location which ranged from 4.41 to 8.43 pCi/g (dry) . This activity was attributed to naturally occurring l radioisotopes and decay products present in soil. This a value 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 6.53 to 16.65 l W pCi/g(dry). The majority of this activity was attributed to naturally occurring K-40. These values are comparable with the gross beta activity detected in the E preoperational program which ranged from 7.0 to 17.2 pCi/g 3 (dry). I lll-34 I I

Bottom Sediments Samples of bottom sediments are collected from ~Clinton Lake at six locations and Lake Shelbyville at one location. Radiological analyses of bottom sediments primarily provide information about the amount of radionuclides avai.lable 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. 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 control and indicator sample locations. Cs-137 and Sr-90 was detected in samples from both indicator and control locations. Both radioisotopes are fission products.

Gross alpha activity in samples of bottom sediments collected from both lakes ranged from 4.36 to 22.47 pCi/g (dry). 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 7.09 to 32.69 pCi/g (dry) . 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). Acuatic Vecetation ( Perichyt on). 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 of the permanently anchored buoys or natural substrate. Periphyton absorb trace elements and 111- 3 5

I h 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 E large surface-to-volun:= ratio. Cell division usually 5 occurs once every one or two days and, as a result, half of the cell wall is a new surface for sorption. 3 Periphyton represent one of the earliest links in the food g 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 g is limited) at the indicator locations and semiannually at W the control location and analyzed by gamma spectroscopy. Periphyton analyses are performed because of their sensitivity to the presence of radionuclides in the aquatic environment due to bio-magnification. Using periphyton as biomonitors for radionuclides in 5 aquatic systems can be a highly sensitive and qualitatively ef fective means of environmental monitoring 3 around nuclear power plants that release radioactive 3 effluents to aquatic systems. It enables the Radiological Environmental Monitoring Program to determine the relative presence of radioactivity before it becomes a problem. The results of the gamma isotopic analyses on periphyton samples detected concentrations of naturally occurring radioisotopes and one fission product, Cs-137. Concentrations for Cs-137 ranged from 0.026 to 0.091 pCi/g (wet) . Preoperational results for Cs-137 showed a concentrations ranging from 0.042 to 0.15 pCi/g(wet). The g presence of Cs-137 is attributed to previous nuclear weapons testing and atmospheric fallout from the accident at Chernobyl.

E. Terrestrial Monitorina In addition to the diact radiation, radionuclides present in the atmosphere expose individuals when deposited on surfaces (e.g., plants and soil) and are subsequently ingested directly by man or indirectly by consumption of animal products (e.g., meat and milk) . To monitor this food pathway, samples of green leafy vegetables, grass, milk and meat are analyzed. Surface soil samples are collected and analyzed annually at the sewage sludge application site to ensure 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 four other locations 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. In addition to naturally occurring radioisotopes, Sr-90 and Cs-137 were found in several 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 Power Station had no measurable contribution to the 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 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. Results of the analyses showed positive concentrations of K-40 and Sr-90 ranging from 1130 to 1600 pCi/l for K-40 and 0.6 to 2.8 pCi/l for Sr-90. Preoperational activity of K-40 in milk ranged from 706 to 1375 pCi/1. Strontium-111- 3 7

I 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 of the milk samples collected. Figure 10 presents the Sr-90 results graphically.

These samples are collected twice a month during May 3 through October and once a month during November through 5 April (when available). Grass samples are analyzed for gamma isotopic activity including I-131. The results of the analyses showed only naturally occurring Be-7 and K-40 in these samples. Iodine-131 was not detected in any of the grass samples collected.

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 distance which is considered to be unaffected by plant operations. Samples are collected once a month during the growing season (June through September) and analyzed for gross beta and gamma isotopic activities including I-131. I I I t 111- 3 8 I I

Meat As an additional check on the presence of radioactive materials in terrestrial exposure pathways, annual samples of beef liver, beef thyroid and edible beef portions are collected from an animal raised near the Clinton Power Station. These samples are analyzed for gamma isotopic activity including I-131. The results of the gamma isotopic analysis showed only naturally occurring K-40 in all three samples at 2.44 and

Soil Soil samples adjacent to air sample stations are collected triennially from three indicator locations and one control location. The samples are collected to monitor the potential buildup of atmospherically deposited radionuclides. One soil sample was collected from an area where Clinton Power Station land applies processed sewage sludge from the Clinton Power Station Sewage Treatment Plant. Soil samples are sifted to remove any stones or debris, then dried and analyzed. All soil samples are analyzed for gross beta, gross alpha and gamma isotopic activities. The results of the gross beta activities ranged from 17.92 to 27.47 pCi/g(dry). Gross alpha activities ranged from

Water Monitorina Water monitoring provides for the collection of drinking water, surface water and ground water (well water) samples to detect the presence of any radioisotopes related to the operation of the Clinton Power Station. The only identified user of water from Clinton Lake for g domestic purposes is the Clinton Power Station; ell others g potentially exposed to any radioisotopes reseased into surface or ground water would not be affected for several years. Samples taken were analyzed for naturally occurring beta and man-made radioactive isotopes. Average gross concentrations in surface, drinking and well water are E presented in Table 7 at the end of this section. 5 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 by the contracted laboratory service is a composite of the g individual samples collected throughout the month. The g monthly composite sample is analyzed for gross A alpha, portion of gross beta and gamma isotopic activities. monthly each monthly sample is mixed with the other samples collected during each calendar quarter. The quarterly composite sample is analyzed for tritium. Gross beta activity ranged from 1.6 to 4.4 pCi/1. These E levels are attributed to very fine particles of sediment W containing K-40 which are not removed during the chlorinating and filtration process. Gross alpha activity ranged from 0.6 to 1.1 pCi/1. Preoperational result were all below the lower limits of I lll-42 I

detection except for one result which was 0.4 pCi/1. These levels 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 effects on drinking water resulting from operation of the Clinton Power Station. l Surface Water Composite water samplers are installed in three locations to sample surface water from Clinton Lake. These samplers collect a small volume of water at regular intervals and discharge it to a large sample collection bottle. These bottles are collected monthly. Two of the composite samplers are located upstream from Clinton Power Station and are unaffected by plant liquid releases downstream. The other composite sampler is positioned to sample the water released from the plant at the start of the plant discharge flume. Grab samples were 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 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 quarterly from composites of monthly samples from all composite sample locations. Results of all gross beta analyses ranged from 1.4 to 6.0 pCi/l at the indicator locations and 2.0 to 2.2 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. 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), previous nuclear weapons testing increased the pre-1960 levels of tritium (6-24 pCi/1) by a factor of approximately fif ty (300-1200) . 111- 4 3 1

I Gamma-emitting radioisotopes were all below the lower , limits of detection, and there was no iodine-131 detected in any surface water samples collected. Gross alpha activity was detected in several of the surface water samples analyzed. These results ranged from 0.7 to 9.1 pCi/1. Preoperational gross alpha activity 3 ranged from 1.3 to 1.9 pCi/1. These results were g attributed to naturally occurring radioisotopes, such as U-238 and Ra-226, suspended as fine sediment particles in water. These results show no measurable change in radioactive material concentration in surface water due to operation of the Clinton Power Station. Well Water Every two weeks samples are collected from the well serving the Village of DeWitt (both treated and untreated l W l samples are obtained) and from a well serving the Illinois l Department of Conservation at the Mascoutin State l Recreational Area. Each sample ir analyzed for I-131. 3 All samples drawn from the same well during a particular g month are combined and analyzed for gross alpha, gross l beta and gamma isotopic activities. In addition, a portion of each monthly composite is added to the quarterly composite sample and is analyzed for tritium. Results of the gross beta analyses ranged from 1.3 to 5.3 E pCi/1. Preoperational gross beta activity ranged from 1.1 5 to 5.1 pCi/1. The gross beta activity was attributed to naturally occurring K-40 suspended as fine sediment particles in water Results of the gross alpha analyses ranged from 1.2 to 3.5 pCi/1. Preoperational gross alpha activity ranged from l 5 0.9 to 1.8 pCi/1. Gross alpha activity can be attributed to naturally occurring radioisotopes, such as, U-238 and Ra-226, suspended as fine sediment partirleu in water. Gamma-emitting radioisotopes were all below the lower limits of detection. Tritium and I-131 were not detected in any well water samples collected. These results show no measurable change in radioactive material concentration in well water resulting from operation of the Clinton Power Station. I I 111- 4 4 I

I: G. Ouality Assurance Proaram J. establish confidence that data developed and reported are accurate and precise, all REMP activities are E incorporated into the Illinois Power Company Quality W Assurance (QA) program of audits and surveillances. The Quality Assurance program requires: Participation in intercomparison programs, such as the EPA cross-check program. Audits of the analysis laboratory functions and facilities.

  • 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.

Appro.ximately 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 Programs Group of l the Plant Radiation and Chemistry Department to ensure the required minimum sensitivities have been achieved and the proper analyses have been performed. l Teledyne participates in the several cross-check programs including the EPA cross-check program. Participation in cross-check programs provides assurance that the m l laboratory is capable of meeting widely-accepted criteria g l for radioactivity analysis. l Results of the 1997 Teledyne cross-check programs are I shown in Appendix D. H. Chances to the REMP Durina 1997 I l 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 or new regulatory l requirements, Quality Assurance audits or supplemental W periodic and long-term sampling and analyses. During 1997, there were no changes to the REMP program as required by the Off-Site Dose Calculation Manual. Other changes that took place are as follows: 111- 4 6 I li l

1. Goat milk location CL-98 was deleted from the program because the tenant no longer milked the animals and had no plans on milking them in the near future.
2. Grass sampling at location CL-11 was deleted because there were two control locations where grass samples were being taken. The decision to keep CL-116 as the control location was primarily based on this site currently being used as a control location for milk.
3. Surface water grab sample at locations CL-9 and CL-10 were discontinued. Because surface water composite samples are being taken at two upstream locations and one downstream location it was decided that this degree of redundancy for surface water sampling was unnecessary.

IV. 1997 ANNUAL LAND USE CENSUS A land use census is performed to ensure that changes in the use of areas at and beyond the site boundary are identified and that any necessary modifications to the REMP are made. The land use census is performed to identify within a distance of 5 miles (8 km), the locations in each of the 16 meteorological sectors of the nearest milk animals, the nearest residence *and the nearest garden of greater than 500 square feet (50 m) 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 Annual Land Use Census was conducted during the growing season satisfying the CPS Offsite Dose Calculation Manual requirements. Approximately 190 residences were surveyed by either direct contact, mailed in questionnaire, telephone, or direct observation. Data for this census was obtained using the following means: o Performed door-to-door solicitation of residences / land owners identified in the previous year's Annual Land Use Census and the most current IV-1

I DeWitt County plat book. If a resident was 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 W' 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 Annual Land Use Census results were examined to ensure that the REMP will provide representative measurements of radiation and radioactive materials in those exposure a pathways and for those radionuclides that lead to the g highest potential radiation exposures to the general public resulting from Clinton Power Station operations. l Using the Annual Land Use Census results and utilizing effluent data supplied by the CPS Chemistry Group, an l evaluation is performed to ensure that the current ODCM 3 l sample location requirements are met. On the basis of this evaluation no changes to the REMP were made. 3 I I I I I I I I I IV - 2 I-3

I Exceptions to the REMP During 1997 Data from the radiological analysis of environmental samples are routinely reviewed and evaluated by the Clinton Power Station (CPS) Radiological Programs Group. This data is a checked for LLD compliance, anomalous values, quality g control sample agreement, and any positive results which are inconsistent with expected results or which exceed any Offsite Dose Calculation Manual (ODCM) reporting levels. E Reporting levels for radioactivity concentrations in E environmental samples required by the CPS-ODCM 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 siteets for any indication of collection or delivery errors, E tampering, vandalism and equipment calibration or 3 malfunctions due to electrical power failure, weather conditions, etc.
  • 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
  • Review CPS effluent reports
  • Recount and/or reanalyze the sample
  • Collect additional samples as necessary During 1997, no investigations were performed as a result of reaching any ODCM reporting levels. All sample analysis y required by the ODCM achieved the LLDs specified by ODCM Table 5.1-3. Sampling and analysis exceptions are listed in Table A-2 of this appendix.

1. Jan 29 Air sampler elapsed timers at CL-2 and CL-3 off by 9.5 m and 9.3 hours respectively due to a power outage during g the sample period. The exact reason for the power outage was unknown. The elapsed timers were used for sample volume calculations.
2. Feb 19 Air sample elapsed timer at CL-8 was found not working after 122.4 hours of operation. Another timer was installed. Actual time used for sample volume calculation.
3. May 21 Air sampler at CL-11 unable to obtain the minimum air sample volume for the sample period due to a decrease in the air sampler flow rate. The exact cause for this a was unknown. The regulator was readjusted and checked g the next day and no problem was noted for the following sampling period. The analysis of the data indicated the sample to be unreliable and inconsistent with the E other air sample results for the sampling period. W Air sample elapsed timer at CL-8 was found not working g because the timer gears did not engage during reset. g Timer was reset properly for the following sample period. Ac'ual t time used for sample volume calculation.
4. Jun 25 Unable to obtain three different types of broadleaf E vegetation at CL-115. Only lettuce was available for 5 collection due to immature plant growth.

Unable to obtain three different types of broadleaf vegetation at CL-118. Only two types were available for collection due to immature plant growth.

5. July 30 Air sample pump at CL-11 found not working. Discarded the sample and replaced the air sample pump.

6. October 15
        . Air sample pump at CL-3 found deenergized with 121.7 hours of operation. Loss of power was due to a wiring I      short in the breaker box.        As left values used for I      sample volume calculation.           Analysis result was consistent with the other stations' air sample results and considered valid.        Wiring in breaker box was repaired on 10/17 at 13:00 hours.
7. October 22 Air sample taken at CL-3 did not meet the minimum required sample volume due the 10/15 incident. The sample was still analyzed and the result was considered valid and consistent with the other stations' air sample results.
8. November 19 Air sample pump at CL-2 found with a low flow-rate.

The exact cause was unknown. The analysis of the data indicated the sample to be unreliable and inconsistent with the other air sample results for the sampling period. ADDITIONAL LOCATIONS (NON-REQUIRED)

Onty ODCM required LLDs and detectable activity (excluding some naturally occurring actsvity I.e., Bi-212) results are l reported in this table. All sample results can be found in Appendix E of this report. Column 3: The ODCM required LLD is given is given when applicable. LLD reported iu the highest of those reported for each of analysis during the year; if all analyses reported po.sitive values, no LLD is repotted. It should be noted that, in most cases, the CPS REMP uses lower detection limits than required. Column 4: Samples taken at indicator Locations during an operational radiological environmental monitoring 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.

                     'T' 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 effluent stack in miles, and the letter (s) name of the compass sector in the direction of the sample location from the CPS gaseous effluent stack. The location with the highest annual mean is compared 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 factors. Sample results are used as reference for the controllocation. 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. B-15

APPENDIX D 1997 Radiological Environmental Monitoring Program Quality Control Check Results A. E D-1

I interfaboratory Comparison Proaram Results Teledyne Brown Engineering Environmental Services Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (cross-check) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's analytical procedures and to alert it to any possible problems. Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency repc.ts the known values to the participant laboratories and specifies control limits. Results consistently higher or :ower than the known values or outside the control limits indicate a need to check the instruments or procedures used. Out-of-limit results are explained directly below the result. e The results in Table D-1 were obtained through participation in the environmental sample cross-check program for water during the past twelve months. This program is conducted by the US Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada. e The results in Table D-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various Intemational intercomparisons of Environmental Dosimeters under the sponsorships listed in Table D-2. Also Teledyne testing results are listed, o Table D-3 lists results of the analyses o.. in-house " spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. e Table D-4 lists results of the analyses on in-house " blank" samples for the past twelve months. The results in Table D-5 were obtained through participation in the Environmental Measurement Laboratory (EML) Quality Assessment Program. The following page lists acceptance criteria for " spiked" samples. I I I I D-2 I I
