SUMMARY
This report describes the Annual Radiological Environmental Monitoring Program (REMP) conducted near the Clinton Power Station (CPS) during the 2001 calendar year. The REMP was performed as required by the CPS Operating License issued by the United States Nuclear Regulatory Commission (NRC). 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 2001, one-thousand-four-hundred-sixty-seven (1,467) environmental samples were collected. These samples represented direct radiation; atmospheric, terrestrial, and aquatic environments along with Clinton Lake surface water and public drinking water samples. Subsequently, one-thousand-eight hundred-nine (1,809) analyses were performed on these environmental samples.
Results of the analyses showed natural radioactivity and radioactivity attributed to other historical nuclear events. The radioactivity levels detected were similar to the Pre-Operational levels found prior to unit start-up. The CPS Pre Operational REMP Report documented natural background radionuclides and man-made radioactivity in the environment surrounding CPS.
Radiological environmental measurements taken during 2001 demonstrated that operational and engineered controls on the radioactive effluents released from the plant functioned as they were designed. Any radioactivity that was detected in the environment at Indicator Locations was appropriately compared with both the measurements at Control Locations and Pre-Operational results.
There were zero (0) radioactive liquid releases from CPS during 2001.
Releases of gaseous radioactive materials were accurately measured in plant effluents. There were no gaseous releases that even approached 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 effluents from Clinton Power Station was less than 0.003 mRem.
All comparisons among Operational Data and Pre-Operational Data showed that during 2001, the operation of Clinton Power Station had no measurable effects upon the surrounding environment.

INTRODUCTION 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 of plant operations. The primary concern is what impact - if any - the radioactive materials released from CPS will have on the general public.
A. CHARACTERISTICS OF RADIATION Atoms whose nuclei contain an excess of energy are called radioactive atoms. They release this excess energy by expelling electromagnetic or particulate radiation from their atomic centers to become stable (non-radioactive). This process is called "radioactive decay".
Gamma rays and X-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 an alpha or beta particle, or has no charge, like a neutron.
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 millions of years. Radionuclides may decay directly into stable elements or may undergo a series of decays until they ultimately reach a stable element.
Radionuclides are found in nature such as radioactive uranium, thorium, carbon, and potassium, and may also be produced artificially in accelerators and nuclear reactors such as radioactive iodine, cesium, and cobalt.
TYPICAL NATURALLY TYPICAL MAN-MADE OCCURRING RADIONUCLIDES RADIONUCLIDES Uranium Iodine Thorium Cesium Carbon Cobalt Potassium Strontium Lead Barium The activity of a radioactive source is the average number of nuclear disintegrations (decay) of the source per unit of time. The unit of activity is called the curie. For example, a one-curie radioactive source undergoes 2.2 trillion disintegrations per minute. When compared against nuclear power plant effluents and environmental radioactivity however, this is a very large unit of measure. Therefore, two sub-fractional units - the microcurie and the picocurie - are more commonly used terms.
1 curie (Ci) = 2,220,000,000,000 disintegrations / minute 1 millicurie (mCi) = 2,220,000,000 disintegrations / minute 1 microcurie (ptCi) = 2,220,000 disintegrations / minute 1 nanocurie (nCi) = 2,220 disintegrations / minute 1 picocurie (pCi) = 2.22 disintegrations / minute
-- page 7 of 122 --
The microcurie (pCi) is one millionth of a curie (Ci) and represents 2.2 million decays per minute. The picocurie (pCi) is one millionth of a microcurie and represents 2.2 decays per minute. Another way of comparing the pCi and the Ci is by an analogy with distances. A picocurie would be the width of a pencil mark while a curie would be the equivalent of one-hundred (100) trips around the earth.
Radioactivity is related to the half-life and the atomic mass of a radionuclide. For example, Uranium-235 (U.3 .) with a half-life of 704 million years requires over a half ton - 1,019 pounds - to equate to an activity of one curie. Whereas Iodine-131 (I131) with a half-life of 8.04 days requires 0.0000000176 pounds to equate to an activity of one curie.
Any mechanism that can supply the energy necessary to ionize an atom, break a chemical bond or alter the chemistry of a living cell are capable of producing biological damage. Electromagnetic and particulate radiation can produce cellular damage in any of these ways. In assessing the biological effects of radiation, 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. When radioactive elements enter the body through inhalation or ingestion, their distribution may not be uniform.
TARGET TISSUE NUCLIDE Bone Strontium-90 (Sr9 Kidney Uranium-235 (U235)
Thyroid Iodine-131 (1I13)
Muscle and Liver Tissue Cesium-137 (Cs 13 )
Gastrointestinal Tract Cobalt-60 (Co°)
For example, radio-iodine selectively concentrates in the thyroid gland, whereas radio-cesium collects in muscle and liver tissue and radio strontium collect in mineralized bone. The quantity and the duration of time that the radionuclide remains in the body also influence the total dose to organs by a given radionuclide. Owing to radioactive decay and human metabolism factors, some radionuclides stay in the body for very short periods of time while others remain for years.
The amount of radiation dose that an individual receives is expressed in Rem. Since human exposure to radiation typically involves very small exposures, the millirem (mRem) is the unit most commonly used. One millirem is equal to one thousandth of a 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
-- page 8 of 122 --
second of our lives, over seven thousand atoms undergo radioactive decay in the body of the average adult.
Radioactive elements have always been a part of our planet and everything that has come from the earth - including our own body - is therefore, naturally radioactive.
Natural Radionuclides in the Earth's Crust Potassium-40 (K40) Radium-226 (Ra 22 6)
Uranium-238 (U238 ) Radon-222 (Rn 222)
Thorium-232 (Th 21 2 ) Lead-204 (Pb 20 4 )
Examples of radioactive materials found in the Earth's crust today consists of radionuclides such as Potassium-40, Uranium-238, Thorium 232, Radium-226 and Radon-222. These radionuclides are introduced into the water, soil and air by such natural processes as volcanic activity, weathering, erosion and radioactive decay.
Some of the naturally occurring radionuclides - such as radon - are a significant source of radiation exposure to the general public. Radioactive radon is a chemically inert gas produced naturally in the ground as a part of the uranium and thorium decay series. Radon continues to undergo radioactive decay, producing new naturally radioactive materials called
'radon daughter products'. These new products - which are solid particles not gases - can adhere to surfaces such as dust particles contained in the air.
Concentrations of radon in the air vary and are affected by concentrations of uranium and thorium in the soil as well as altitude, soil porosity, temperature, pressure, soil moisture, rainfall, snow cover, atmospheric conditions and the time of the season. Radon can move through cracks and openings into basements of buildings and become trapped in small air volumes indoors. Thus, indoor radon concentrations are usually higher than those found outdoors. Building materials such as cinder blocks and concrete are radon sources. Radon can also be dissolved in well water and contribute to airborne radon in houses when released through showers or washing.
Dust containing radon daughter particles can be inhaled and deposited on the surface of an individual's lung. Radon daughters emit a high-energy alpha radiation dose to the lung lining. Table 1 shows the average annual effective dose due to radon.
About three-hundred (300) cosmic rays originating from outer space pass through each person every second.
-- page 9 of 122 --
Cosmic-Ray-Activated Radionuclides Beryllium-7 (Be 7 ) Tritium (H3 )
Beryllium-10 (Be 1l) Sodium-22 (Na 22)
Carbon-14 (C1 4 ) 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 stays 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 while milk contains measurable amounts of Potassium-40. Sources of natural radiation and their average contributing radiation doses are also 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 can also vary widely from location to location. The average individual in the United States receives approximately three-hundred (300) mRem per year, just from naturally occurring background radiation sources.
In some areas of the United States, the dose from natural radiation is significantly higher. Residents of Colorado - five-thousand (5,000) feet above sea level - will receive additional dose due to the increase of cosmic and terrestrial radiation levels. In fact, for every one-thousand (1,000) feet in elevation above sea level, an individual will receive an additional one (1) 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 approximately fifty-three (53) mRem.

Smaller doses from man-made sources come from consumer products - such as televisions, smoke detectors, and fertilizers - as well as fallout from prior nuclear weapons testing, the 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 a nuclear weapon. 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"'s) Strontium-90 (Sr")
Strontium-89 (Sr 89) Cesium-137 (Cs 137 )
There are approximately two-hundred (200) radionuclides produced in the nuclear weapon detonation process with a number of these detected as fallout. The radionuclides found in fallout that produce the majority of the fallout radiation exposures to man are Iodine-131, Strontium-89, Strontium-90, and Cesium-137.
C. DESCRIPTION OF THE CLINTON POWER STATION The Clinton Power Station (CPS) is located in Harp Township, DeWitt County, Illinois. It is approximately six (6) miles east of Clinton, Illinois.
The station - including the V-shaped cooling lake - coupled with the surrounding AmerGen Energy Company, LLC owned land encloses approximately 13,730 acres. This includes the 4,895 acre, man-made cooling lake and about 452 acres of property not owned by AmerGen. The plant is situated 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 aforementioned 13,730 acres lie within Wilson, Rutledge, DeWitt, Creek, Nixon and Santa Anna Township[s].
The cooling lake was formed by constructing an earthen dam near the confluence of Salt Creek and at the North Fork of Salt Creek. The resulting lake has an average depth of 15.6 feet which includes an ultimate heat sink of approximately 590 acre-feet. The ultimate heat sink provides for a sufficient water volume and cooling capacity for approximately thirty (30) days of operation without any makeup water.
Through arrangements made 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,
-- page 12 of 122 --
boating, water-skiing, hunting and fishing. Recreational facilities exist at Clinton Lake and accommodate up to 11,000 people per day during peak usage periods. The outflow from Clinton Lake falls into Salt Creek and then flows in a westerly direction for about fifty-six (56) miles before joining in with the Sangamon River. The Sangamon River drains into the Illinois River that enters the Mississippi River near Grafton, Illinois. The closest use of downstream water for drinking purposes is approximately 242 river miles downstream from Clinton Lake at Alton, Illinois as verified from the Illinois Environmental Protection Agency Public Water Service. Although some farms throughout the Salt Creek drainage area use irrigation water downstream of Clinton Lake, this irrigation water is drawn from wells and not directly from the waters of Salt Creek.
Approximately 810,000 individuals live within fifty (50) miles of the Clinton Power Station. Over half are located in the major metropolitan centers of Bloomington - Normal which is located about twenty-three (23) miles to the north northwest, Champaign - Urbana which is located about thirty-one (31) miles to the east, Decatur which is located about twenty-two (22) miles to the south southwest and Springfield which is located about forty-eight (48) miles to the west southwest. The nearest city is Clinton, the county seat of DeWitt County. The estimated population of Clinton is about 8,000 residents. Outside of the urban areas, most of the land within fifty (50) miles of the Clinton Power Station is used for farming. The principal crops grown are corn and soybeans.
D. NUCLEAR REACTOR OPERATIONS The fuel of a nuclear reactor is made of the element uranium in the form of uranium oxide. The fuel produces power by the process called
'fission'. During fission, the uranium atom absorbs a neutron and splits to produce fission products, heat, radiation and free neutrons. The free neutrons travel in the reactor core and further absorption of neutrons by uranium permits the fission process to continue. As the fission process continues, more fission products, more radiation, more heat and more neutrons are produced and a sustained reaction occurs. The heat produced is extracted from the fuel to produce steam, which subsequently 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. Stable atoms in the materials that make up the components and structures of the reactor may absorb neutrons that are not absorbed by the uranium fuel. In such cases, stable atoms often become radioactive. This process is called 'activation' and the radioactive atoms, which result, are called 'activation products'.

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

The fuel rods are arranged in arrays called bundles that are supported within the massive steel reactor vessel.
The voids between the fuel rods are filled with water. The heat released during the fission of fuel atoms is transferred to the water surrounding the fuel rods. A type of pump that contains no moving parts - a jet pump - and recirculation water pumps are used to force the water to circulate through the fuel bundles to assure even cooling and heat removal from the fuel rods. Some of the water that absorbs heat from the fuel rods is changed to steam. The steam is used to drive a turbine that is coupled to a generator, thereby completing the conversion of nuclear energy released during fission into electricity.
After the steam passes through the turbine, it is condensed back into 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 mix 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 coolant system although small leaks from the primary system may occur.
E. CONTAINMENT OF RADIOACTIVITY During normal operating conditions, essentially all of the radioactivity is contained within the first of several barriers - that collectively - prevent radioactivity from escaping into 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 (70) foot high vessel with steel walls ranging from four (4) to seven (7) inches thick that encases 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 a steel-lined, four (4) 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 operations or from radioactive materials created during reactor operations.
-- page 16 of 122 --
F. SOURCES OF RADIOACTIVE EFFLUENTS In an 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 that have been activated, also get into the primary coolant.
Demineralizers from the water purification systems remove many soluble fission and activation products such as radioactive iodines, strontiums, cobalts and cesiums. The noble gas fission products, activated atmospheric gases introduced with reactor feedwater and some of the volatile fission products such as iodine and bromine, carry over from the reactor pressure vessel to the condenser.
The steam jet air ejectors remove the gases from the condenser and transfer them to the off-gas treatment system. Within the off-gas treatment system, these 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, Rad Waste and Fuel Buildings. The noble gases become part of the gaseous wastes while the remaining radioactive liquids are collected in sumps and processed for reuse. Processed primary coolant water that does not meet chemical specifications for reuse may also become wastewater. These represent the principal sources of liquid effluents.
Information about radioactive effluents can be found in the Annual Radioactive Effluent Release Report. This report contains a detailed description of all radioactive releases from CPS and the resulting radiation doses for the reporting period.
G. RADIOACTIVE WASTE PROCESSING In a normal operating nuclear power plant, radioactive liquid and gaseous wastes are collected, stored and then processed through treatment systems to remove or reduce most of their radioactivity (excluding tritium) prior to reuse within the plant or discharged to the environment.
These processing systems are required by the Clinton Power Station (CPS)
Offsite Dose Calculation Manual (ODCM) to be installed and operable to help ensure all releases of radioactive liquid and gaseous effluents are As Low As Reasonably Achievable (ALARA). As a matter of commitment, CPS strives to be a zero (0) liquid release plant and was able to accomplish that commitment throughout 2001.
-- page 17 of 122 --
The liquid waste treatment systems consist of filters, demineralizers and evaporators. Liquid wastes are routed through the waste evaporators to be degassed and distilled thereby reducing their volume and concentrating their radioactivity. The distillates are further treated through demineralizers and filters and transferred to the waste evaporator condensate storage tanks. Liquid wastes are processed through the appropriate portions of the liquid waste treatment system to provide assurance that the releases of radioactive materials in liquid effluents will be kept ALARA.
Liquid wastes may be discharged into the plant cooling water stream that varies from approximately 5,000 gallons per minute - when the unit is shutdown - to 567,000 gallons per minute when the unit is at full power. If a planned release were to occur, liquid effluents would be thoroughly mixed with - and diluted by - the plant cooling water as it traverses down a 3.4 mile discharge canal before entering Clinton Lake east of DeWitt County Road 14.
The Clinton Power Station Offsite Dose Calculation Manual requires that liquid effluents will not have a higher concentration of any radioisotope than which is established for continuous exposure to the general public.
This requirement is satisfied at the point in which the liquid effluent is first introduced to the cooling water flow. Thus, this additional dilution - which occurs along the 3.4 mile cooling water canal - further reduces the original concentration[s] of radioisotopes by 1/73 (at minimum flow during unit shutdown) and by 1/1890 (at maximum flow during unit operation) prior to the water entering Clinton Lake.
The concentrated radioactive solids captured from the liquid waste treatment system are processed and temporarily stored on-site until shipped off-site for disposal at a licensed low-level waste disposal facility.
The gaseous effluents from the main condenser are held up in the off-gas charcoal beds for a minimum of forty-six (46) hours. With most of the radionuclides present having a radioactive half-life of less than eight (8) hours, this hold up process allows for their radioactive decay. If the gaseous effluents from the ventilation exhaust system for the Containment Building and Secondary Containment structure exceed conservatively established set points, these effluents are processed through charcoal beds and High Efficiency Particulate Air (HEPA) filters within the Standby Gas Treat-ment System before being released to the environment.
The combination of HEPA filters and charcoal bed filtration is rated to be 95% efficient for removing iodines and greater than 99% efficient for removing any particulate material that is larger than one micron (one millionth of one inch) in diameter.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM
Ill. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. Program Description The Clinton Power Station is required to maintain a Radiological Environmental Monitoring Program (REMP) 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 REMP is an extensive program of sampling, measuring and analyzing that was instituted to monitor the radiological impact of reactor operation[s] on the environment. Objectives of the program include the following:
"* identification, measurement and evaluation of existing radionuclides in the environs of the Clinton Power Station and fluctuations in radioactivity levels that may occur
"* evaluation of the measurements to determine the impact of Clinton Power Station operations relative to the local radiation environment
"* collection of data needed to refine environmental radiation transport models used in offsite dose calculations
"* verification that radioactive material containment systems are functioning to minimize environmental releases to levels that are ALARA
"* 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 (2) phases, Pre-Operational (Pre-Op) and Operational.
The Pre-Operational portion of the program was initiated in May 1980 and was completed on 27 February 1987 to establish the baseline for the local radiation environment. Assessment of the operational impact of the Clinton Power Station on the radiation environment is based on data collected since the beginning of reactor operation[s]. The operational phase implements confirmatory measurements to verify that the in-station controls for the release of radioactive material are functioning as they were designed to.
AmerGen Energy Company, LLC currently maintains a contract with Environmental Inc. Midwest Laboratory, for the analysis of all radiological
-- page 19 of 122--
environmental samples. Environmental Inc. is located in Northbrook, Illinois. Samples are currently collected by AmerGen Energy Company personnel and then shipped to the Environmental, Inc. laboratory for analysis. After analysis, environmental samples are saved at the laboratory for a specified period of time in case an additional follow up analysis is required. Analytical results are then reported back monthly to the ODCM Program Owner.
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 basic pathways of gaseous and liquid radioactive effluents to the public. The "important pathways" selected are based primarily on how radionuclides move through the environment that will eventually expose the public - taking into consideration - man's use of the environment. The scope of the program includes the monitoring of five (5) environmental elements:
0 direct radiation 0 atmospheric 0 aquatic 0 terrestrial environments 0 ground and surface water Each pathway is monitored at "Indicator" and "Control" Locations.
Indicator Locations are generally within a ten (10) mile radius of the station that is expected to mimic station effects, if any exist. Control Locations are located greater than ten (10) miles from the plant - far enough away - so as not to be influenced by unit operations. These control samples provide the basis by which to measure any fluctuations in radioactivity from Indicator Locations relative to natural phenomena and fallout. Thus any increase in radioactive material concentration from an Indicator Location may be - due in part - to unit operations.

Sample Analysis Concentrations of radioactivity present in the environment will vary due to factors such as weather conditions, variations in the sampling collection technique and during sample analysis.
Several types of measurements may be performed to provide information about the types of radiation and radionuclides present.
Analyses that are performed on environmental samples collected for the CPS REMP include the following:
"* Gross alpha and beta analysis
"* Gamma spectroscopy analysis
"* Tritium analysis
"* Strontium analysis
"* Gamma dose (TLDs only)
A gross alpha and beta analysis measures the total amount of alpha and beta emitting radioactivity present in a sample. Both radiation[s] may be released by many different radionuclides. Gross activity measurements
- while useful as general trend indicators - are not used to establish specific radionuclide concentrations. Therefore, gross activity analysis will only indicate whether the sample contains normal or abnormal concentrations of alpha or beta emitting radioactivity and serves as a precursor in which to identify samples that may require additional follow up analysis.
Samples are primarily analyzed for plant-contributed radionuclides released to the environment. Since naturally occurring radionuclides are abundant in environmental samples - irrespective of CPS Operations positive results for certain radionuclides and gross alpha / beta measurements are discussed further in this section of the report.
-- page 30 of 122 --
B. Direct Radiation Monitoring Radionuclides present in the air - in addition to those deposited in or on the ground - will cause human exposure by immersion in the atmosphere or by deposition on the ground. TLDs (Thermo-Luminescent Dosimeters) are used to measure the ambient gamma radiation levels at many locations surrounding Clinton Power Station.
TLDs are crystalline devices that store energy when they are exposed to radiation. They can be processed months after their exposure with minimal loss of this information. This makes them well suited for quarterly environmental radiation measurements.
During TLD processing, stored energy is released as light and measured by a TLD reader. The light intensity is proportional to the radiation dose the TLD was exposed to. The TLDs used for environmental monitoring around the Clinton Power Station are capable of measuring environmental levels of radiation to approximately twenty (20) mRem per quarter.
Monitoring stations are placed near the site boundary and approximately five (5) miles from the reactor, in locations representing the sixteen (16) meteorological compass sectors. Other locations are chosen to measure the radiation levels at places of special interest such as nearby residences, meeting places and population centers.
Control Locations are located further than ten (10) miles from the site, in areas that will not be influenced by plant operations.
TLD measurements register the gamma ray exposure in milli Roentgen (mR). For reporting purposes mR is numerically equivalent to that of mRem. Consequently, these terms are used interchangeably throughout this Annual Report.
A total of two-hundred-sixteen (216) TLD measurements were made throughout 2001. The average quarterly dose from our Indicator Location[s]
was 18.1 mrem. At our Control Locations, the average quarterly dose was 16.9 mRem. These quarterly measurements ranged from 13.1 to 21.9 mRem for Indicator TLDs and 15.0 to 19.5 mRem for Control TLDs.
Figure 8 compares the 2001 quarterly TLD results with Pre Operational TLD quarterly averages.
Average doses (+/-2 standard deviations) - broken down by calendar quarter - are shown in Table 4 for both Indicator and Control Locations.

C. Atmospheric Monitoring The inhalation and ingestion of radionuclides in the air is a direct exposure pathway to man. A network of ten (10) active air samplers around the Clinton Power Station monitors this pathway. There are nine (9)
Indicator Location air sampling stations strategically located in areas that are most likely to reveal any measurable effects due to the release of radioactive effluents from the Clinton Power Station. The Control Location is located approximately sixteen (16) miles south of the plant in an area that is totally independent from any of the effects from unit operation[s].
Historical meteorological data indicates that this Control Location is normally upwind from the plant.
Mechanical air samplers are used to draw a continuous volume of air through a filter and charcoal cartridge collecting any particulates and radioiodines that may be present in the atmosphere. These samplers are equipped with a pressure-sensing flow regulator to maintain a constant sampling rate of air flow of about one (1) cubic foot per minute (CFM). The total volume is then calculated based upon the amount of time the air sampler was in operation and the flow rate. This air sampling equipment is maintained and calibrated by Clinton Power Station personnel using reference standards that are traceable back to the National Institute of Standards and Technology (NIST).
Air samples are collected every week and analyzed for gross beta and 1131 activities. Quarterly, all air particulate filters collected throughout this 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-lived daughters - produced by the decay of natural radon and thoron - may otherwise mask any plant contributions. Therefore, these filters are not analyzed for at least five (5) days after their collection. This allows for the radioactive decay of short lived daughters, thus reducing their contribution to the overall gross beta activity.
Results from the gross beta airborne particulate analysis provides for comparisons between both Indicator and Control Locations - including those locations relative to spatial and temporal differences - throughout the year. The calculated annual average was 0.025 pCi/in 3 for all Indicator Locations and 0.026 pCi/m 3 for the Control Location. These results are consistent with our Pre-Operational annual averages for both Indicator and Control Locations that were 0.027 pCi/m3 .
The location with the highest calculated annual average was measured at Indicator Location CL-8 that is located 2.2 miles east of the Clinton Power Station. This location had an average concentration of 0.027 pCi/m 3. Individual location averages for the year are presented in Table 5.
Minor fluctuations in the gross beta concentrations were noted throughout 2001. The general trend for average weekly gross beta concentrations from the Indicator Locations correlated to the trend for the Control Locations throughout the monitoring period. This correlation is evidenced by the similarity of the trends in the average monthly gross beta
-- page 33 of 122 --
concentrations displayed in Figure 9. There were no significant differences observed between these individual locations. Monthly averages for Indicator and Control Locations for the year are presented in Table 6.
Fluctuations observed in the gross beta activity over the year can be attributed to changes in the environment, specifically during seasonal changes.
All gross beta concentrations for 2001 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 [Beryllium] was the only gamma-emitting radionuclide detected in analyses of particulate filters.
No measurable contribution to the overall level of airborne particulate radioactivity was identified as a result of unit operations. The radioactivity that was detected - naturally occurring Be 7 - is normally found in the environment and is consistent with the expected concentrations of natural radioactivity and fallout from prior atmospheric nuclear weapons testing.

D. Aquatic Monitoring The Clinton Power Station utilizes a man-made lake as the source of cooling water and returns this used cooling water to the same lake while most nuclear power stations use once-through flow from a river, an ocean or body of water much larger than Clinton Lake. If radioactive liquid effluents were to be discharged from the Clinton Power Station into the cooling water outfall, long-lived radioisotopes could build up over a period time as the same water is reused on successive trips through the plant.
Cooling water that exits from the plant will travel back into the eastern arm of Clinton Lake and then into the northern arm of the lake before returning back into the plant. Although the only user of Clinton Lake as a source of drinking water is CPS itself, 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 from liquid effluents. Aquatic monitoring provides for the collection of fish and shoreline sediments to detect the presence of any radioisotopes related to the operation of the Clinton Power Station. These samples are analyzed for naturally occurring and man-made radioactive materials. Both Indicator and Control Location[s] are sampled.
Indicator samples were taken from various locations throughout Clinton Lake whereas Control samples are obtained from Lake Shelbyville approximately fifty (50) miles south of Clinton Power Station - thus serving as an excellent comparison to unit operations.
In addition to naturally occurring radioisotopes, Sr° was found in one sample. However, the overall concentrations of radionuclides in samples collected near the Clinton Power Station were comparable to the concentrations in samples collected from the Control Location at Lake Shelbyville. The presence of this fission product is attributable to previous nuclear weapons testing and fallout from the accident occurring at Chernobyl. The operation of Clinton Power Station had no measurable contribution to the radioactive inventory of the aquatic environment.
Fish Various samples of fish are collected from Clinton Lake and Lake Shelbyville. From both lakes; these samples consists of largemouth bass, crappie, carp, and bluegill. The selections of these species are the fish most commonly harvested from the lakes by sport fishermen. Fish will ingest sediments during bottom feeding - or prey on other organisms which will also ingest sediments that may otherwise retain radionuclides. A radiological analysis from fish samples provides key information on the potential ingestion of radionuclides by humans via this aquatic pathway.
These samples are collected semi-annually and analyzed by gamma spectroscopy.
The gamma spectroscopy analysis revealed that fish samples showed the presence of naturally occurring K4 ° [Potassium] in all samples.
All other analytical results were less than the lower limit of detection (LLD) for each radionuclide.
-- page 37 of 122 --
Shoreline Sediments Samples of shoreline sediments were collected at both Clinton Lake and at Lake Shelbeyville. Radiological analyses of shoreline sediments provide information on any potential shoreline exposure to humans, determining long-term trends, and the accumulation of long-lived radionuclides from the environment. Samples are collected semi-annually and analyzed for gross beta, gross alpha, Sr9' and gamma isotopic activities.
Shoreline sediment samples are dried prior to analysis and the results are reported in pCi/g dry weight. Naturally occurring radioisotopes were present in samples taken at both Indicator and Control Locations.
There was only one fission product - Sr9 ° - that was detected from the Control Location. The activity detected was well within the range from that measured during the Pre-Operational period.
Isotope Pre-Op Range 2000 Range 2001 Range (pCi/g dry) (pCi/g dry) (pCi/g dry)
Sr 90 0.011 - 0.056 0.014 - 0.044 0.011 - 0.027 E. Terrestrial Monitoring In addition to direct radiation, radionuclides that are present in our atmosphere expose individuals when they are deposited on plant and soil surfaces. Consuming animal products - such as meat and milk subsequently ingests them either directly by man or indirectly. To monitor this food pathway, samples of green leafy vegetables, grass and milk are analyzed.
Surface vegetation samples are collected monthly during the growing season from a number of locations for the purpose of monitoring the potential buildup of atmospherically deposited radionuclides. Because the radionuclides of interest - relative to Clinton Power Station operations - are already present within our environment as a result of several decades of worldwide fallout or because they are naturally occurring, the presence of these radionuclides is anticipated from all of the samples collected. These samples are analyzed by gamma spectroscopy.
The gamma spectroscopy analysis revealed the presence of naturally occurring K40 [Potassium] and Be 7 [Beryllium] in several samples.
All other analytical results were less than the lower limit of detection (LLD) for each radionuclide. 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 (5) mile radius of the Clinton Power Station. Milk samples are collected from a dairy located about fourteen (14) miles west
-- page 38 of 122 --
southwest of the station (twice a month during May through October and once a month during November through April). These samples are analyzed for 131, Sr90 , and gamma isotopic activities.
Results from these analyses showed Sr9 ° concentrations ranging from 0.5 to 3.1 pCi/I [pico-curies per liter of milk]. The analysis of SPO on milk samples was added to the REMP during the operational phase of the program and as such, no Pre-Operational data for this isotope is available
[see below*]. There was no 113 detected in any of the milk samples collected.

Sr9° *Not Available 0.2-3.2 0.5-3.1 Grass In addition to milk samples, grass samples are also collected at three (3) Indicator Locations and at one (1) Control Location. These samples are collected twice a month during May through October and once a month during November through April (when available). Grass samples are analyzed for gamma isotopic activity including r131.
The results from the analyses showed only naturally occurring Be 7 and K4° in these samples. There was no 1131 detected in any of the grass samples collected.
Vegetables The Clinton Power Station obtains broadleaf vegetable samples from three (3) Indicator Locations and at one (1) Control Location. The Indicator Locations are located in the meteorological sectors with the highest potential for surface deposition and the Control Location is in a meteorological sector and distance - approximately thirteen (13) miles downwind - which is considered to be unaffected by unit operations.
Samples are collected once a month during the growing season (June through September) and are analyzed for gross beta and gamma isotopic activities including 1131.
The results from the analyses showed only naturally occurring Be 7 and K40 from these samples. There was no I1`3 detected in any of the vegetable samples collected.
F. Water Monitoring Water monitoring provides for the collection of drinking water, surface water, and ground water (well water) samples to detect the presence of any radioisotopes relative to unit operations at the Clinton Power Station.
-- page 39 of 122 --
The only identified user of water from Clinton Lake for domestic purposes is the Clinton Power Station. Samples taken are analyzed for naturally occurring and man-made radioactive isotopes. Average gross beta concentrations in surface, drinking and well water[s] are presented in Table 7 at the end of this section.
Water monitoring results show no measurable effects resulting from the operation of the Clinton Power Station.
Drinking Water A composite water sampler is located at the Station Service Building that 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 our contracted laboratory service represents a composite of the individual samples that are collected throughout the month. This monthly composite sample is then analyzed for gross alpha, gross beta and gamma isotopic activities. A portion of each of these monthly samples is further mixed with the other monthly samples collected during each calendar quarter. This quarterly composite sample is then analyzed for H3 [Tritium].
Gross beta activity ranged from 0.9 to 2.1 pCi/I. These levels are attributed to very fine particles of sediment containing I<' which are not removed during the chlorination and filtration process.
The results from the H3 and gamma-emitting radioisotope analysis were all less than the lower limit of detection (LLD).
Surface Water Composite Water Samplers are installed at three (3) locations sampling surface water from Clinton Lake. These Composite Water Samplers collect a small volume of surface water at regular intervals and discharge the sample into a large sample collection bottle. Monthly, this water is then collected.
Two (2) of the Composite Water Samplers are located upstream from Clinton Power Station and are therefore unaffected by any plant liquid releases occurring downstream. The other Composite Water Sampler is positioned to sample water being released from the plant at the start of the plant discharge flume. Grab samples are collected from one (1) Indicator Location on Clinton Lake.
Surface water samples are analyzed for gross beta, gamma isotopic, and H3 [Tritium] activities. Additional analyses for gross alpha activity are performed on the upstream water samples. Additional analyses for gross alpha activity and 1131 activity are performed on water samples taken from the discharge flume. Tritium analyses are performed quarterly from all of the monthly composites from all Water Composite Sample locations.
-- page 40 of 122 --
Results of all gross beta analyses ranged from 1.1 to 7.4 pCi/I for the composite water samples and 2.3 to 3.2 pCi/I for the grab samples. Pre Operational gross beta activity ranged from 1.1 to 7.6 pCi/I. These results are attributed to naturally occurring K40 suspended as fine sediment particles in the water. Other types of samples - such as Shoreline Sediments - have further validated the presence of K" in Clinton Lake All samples analyzed for H3 [Tritium] were all less than the lower limits of detection (LLD). Pre-Operational 1-1f [Tritium] concentrations ranged from 220 to 330 pCi/I. As noted in Reference E187, previous nuclear weapons testing has increased the pre-1960 levels of Tritium (6-24 pCi/I) by a factor of approximately fifty (50) to 300-1,200 pCi/I.
Gamma-emitting radioisotopes were all below the lower limits of detection (LLD) and there wasn't any 1131 detected from any surface water sample collected.
Well Water Every quarter - both treated and untreated well water samples - are collected from the well serving the Village of DeWitt and from a well serving the Illinois Department of Conservation at the Mascoutin State Recreational Area. Each sample is analyzed for 1131, gross alpha, gross beta, H3 [Tritium]
and gamma isotopic activities.
Results of the gross beta analyses ranged from 1.9 to 2.4 pCi/l.
Pre-Operational gross beta activity ranged from 1.1 to 5.1 pCi/I. The gross beta activity was attributed to naturally occurring K'4 suspended as fine sediment particles in water.
Gamma-emitting radioisotopes were all below the lower limits of detection (LLD) and there wasn't any 1131 or H3 detected from any well water sample collected.

G. Quality Assurance Program To establish confidence and credibility that the data collected and reported is accurate and precise, REMP activities are incorporated into the Quality Assurance (QA) program, which includes assessments, audits, and surveillances. The Quality Assurance program requires the following:
0 Participation in inter-comparison programs, such as the Environmental Resource Associates (ERA) cross-check program.
0 Audits of analysis laboratory functions and their facilities.
0 Periodic review of the Clinton Power Station procedures specifying sampling techniques.
0 Duplicate analysis of all samples received (excluding TLDs). This requirement is to check laboratory precision.
o The routine counting of quality control samples.
The analytical results provided by the laboratory were reviewed monthly to ensure the required minimum sensitivities have been achieved and the proper analyses have been performed.
Our Vendor - Environmental Inc. - has participated in interlaboratory comparison (crosscheck) programs since the formulation of their quality control program back in December 1971. These programs are operated by agencies which supply environmental type samples - such as milk and water - containing concentrations of radionuclides that are only known to the issuing agency and not the participating laboratory. The purpose of such a program is to provide an independent check on the laboratory's analytical procedures and alert them to any possible problems.
Results from the 2001 Environmental Inc. cross-check program are shown in Appendix A.
H. Changes to the REMP During 2001 On occasion, revisions to the Radiological Environmental Monitoring Program are necessary so as to improve the monitoring of the environmental exposure pathways. These changes may result from items identified during the performance of the Annual Land Use Census, to incorporate revised or new regulatory requirements or Quality Assurance audits.
During the course of 2001, there were no changes to the REMP program as delineated within the Off-Site Dose Calculation Manual.

2001 ANNUAL LAND USE CENSUS
IV. 2001 ANNUAL LAND USE CENSUS Each year an Annual Land Use Census is conducted to ensure that changes in the use of areas - at and beyond the site boundary - are identified and that any necessary modifications to the Radiological Environmental Monitoring Program (REMP) are made. The information gathered during the Annual Land Use Census is used for Radioactive Effluent Technical Specifications (RETS) dose assessments and feeds into the REMP ensuring that these programs are as current as possible.
The Annual Land Use Census is conducted during the growing season satisfying the CPS Offsite Dose Calculation Manual (ODCM) requirements. The Annual Land Use Census is conducted to identify the nearest milk animals, the nearest residence and the nearest garden of greater than five-hundred (500) square feet that produce broadleaf vegetation - all within a distance of five (5) miles - in each of the sixteen (16) meteorological sectors.
The Annual Land Use Census shall also identify - within a distance of three (3) miles - the location in each of the sixteen (16) meteorological sectors all milk animals and all gardens of greater than five-hundred (500) square feet that produce broadleaf vegetation. A detailed summary of the Annual Land Use Census is provided in a separate document and permanently archived at CPS.
In order to assemble as much information as possible, the locations of residences, critical age groups, milk animals, vegetable garden contents, and livestock were recorded for each sector within five (5) miles, as stated above.
These land use parameters are then used in the assessment of potential radiological doses to individuals for the stated sectors. This information provides the most restrictive parameters used for dose assessments that will result in the highest calculated dose within each sector. Additional information regarding dose assessments to members of the public is provided within the 2001 CPS Annual Radioactive Effluent Release Report.
Direct contact, a mail-in questionnaire, telephone, or direct observation surveyed two-hundred forty (240) area residents. The information provided in this section of the report is a summary of the results of the census. The nearest residence, garden, and milk animal in each sector out to five (5) miles are given in Table 8.
Data for this census was obtained using the following means:
o Performed door-to-door solicitation of residences / land owners identified from the previous year's Annual Land Use Census and the most current DeWitt County plat book. If a resident was unavailable for this questioning, a questionnaire was placed on their door requesting them to answer the questions and mailing back to the Station.
o Performed telephone solicitation of person[s] who were unavailable during the door-to-door survey and who did not mail back their questionnaire.
-- page 44 of 122 --
o By direct observation of their land use when the aforementioned methods proved unsuccessful. If an individual was unable to be contacted, then data from the previous year was utilized.
O Contacted several state and local agencies.

(*) None identified within five (5) miles of CPS in this meteorological sector.
The Annual Land Use Census results were validated to ensure that the REMP will provide representative measurements of radiation and radioactive materials from exposure pathways and for radionuclides that lead to the highest potential radiation exposure to the general public resulting from unit operations.
After carefully reviewing the Annual Land Use Census results - coupled with effluent release information - provided by the CPS Chemistry Department, an evaluation is conducted ensuring current ODCM sampling location requirements are satisfied. As a result of that evaluation, no changes to the REMP were required.

Summary of Changes Identified in 2001 Annual Land Use Census Nearest Residence No changes were identified for the nearest residence in the sixteen (16) meteorological sectors.
Garden Census One-hundred-ten (110) gardens within a five (5) mile radius were located in the sixteen (16) geographical sectors surrounding CPS that contained broad leaf vegetation - such as lettuce and cabbage - and were greater than five-hundred (500) square feet.
Changes in census locations for the nearest garden were identified in three (3) of the sixteen (16) geographical sectors and are indicated below:
2000 Census Location 2001 Census Location
> 5 miles SE 4.4 miles SE 1.6 miles W 2.1 miles W 2.3 miles NNW > 5 miles NNW There were no changes or additions to the REMP garden sampling locations as a result of the Garden Census.
Milk Animal Census Milk animals within five (5) miles were located in the sixteen (16) geographical sectors surrounding CPS. Twelve (12) locations were identified within this five (5) mile radius. Only milk animals were specifically identified for this report. Of the livestock identified, milk animals were being raised primarily for nursing (nursing of their calves) and were being used for meat production (for both their own use and sold commercially). There were no residents that milked their animals for any human consumption. Other livestock raised in the area were identified, but will not be addressed within this report.
Changes in the census locations for the nearest livestock / dairy were identified in one (1) of the sixteen (16) geographical sectors and are indicated below:
2000 Census Location 2001 Census Location

Appendix A Interlaboratory Comparison Pro-gram Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) 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 a laboratory's analytical procedures and to alert it of any possible problems.
Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.
The results in-Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.
This program was conducted by the U.S. Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.
The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2. Results of crosscheck testing with Teledyne Brown Engineering are also listed.
Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.
Table A-5 list results of the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.
Attachment A lists acceptance criteria for "spiked" samples.
Out-of-limit results are explained directly below the result.

Column 1 Column 21 Column 31 Column 41 Column 51 Column 6 Column 7 TABLE EXPLANATIONS:
Column 1: The Unit of Measurement describes all the numerical values for LLD, Mean and Range reported for a particular sample medium. For example: the Gross Beta LLD in AIR PARTICULATES is 0.010 pCi/m 3 . Abbreviations used are: pCi/mn 3 = pico-curie per cubic meter of sampled air; mRem/quarter = exposure measured for calendar quarter period; pCi/I = pico-curie per liter of sample; pCi/g = pico curie per gram of sample.
Column 2: The Types of Analyses are described as follows: Gamma Spec =
measurement of each radioisotope in a sample using Gamma Spectroscopy; Gross Betas and Gross Alphas = measurement of the radioactivity in a sample by measurement of emitted betas and alphas - no determination of individual radioisotopes is possible; Tritium = measurement of tritium (H-) in sample by liquid scintillation counting method; TLD = direct measurement of gamma exposure using thermoluminescent dosimeters. Total number of analyses does not include duplicate analyses, recounts, or reanalysis. Only ODCM required LLDs and detectable activity (excluding some naturally occurring activity such as Bi212) results are reported in this table. All sample results can be found in Appendix E of this report.
Column 3: The ODCM required LLD is given when applicable. LLD reported is the highest of those reported for each of the analyses during the year; if all analyses reported positive values, no LLD is reported. 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 a nuclear station. The reported values are the mean or average for the year of all samples of that type which had values greater than the LLD. " f " is the fraction of all the samples taken at all indicator locations for the medium, which reported values greater than the LLD. Example: Seven (7) results greater than LLD out of fifteen (15) samples taken would be reported as 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 name corresponding to 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 control location.
Column 7: NRC Regulations (Branch Technical Position, Revision. 1, November 1979) include a table of radioisotope concentrations that, if exceeded by confirmed sample measurements, indicate that a Non-routine Reported Measurement exists. Such measurements require further investigation to validate the source.

APPENDIX C 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 effluent releases).
Alpha particle - a charged particle emitted from the nucleus of an atom having a mass and charge equal in magnitude to a helium nucleus which has two protons and two neutrons.
Atom - the smallest component of an element having all the properties of that element. Comprised of protons, neutrons and electrons such that the number of protons determines the element.
Background radiation - source of radiation that mankind has no control over, 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 the Clinton Power Station so as not to be influenced by station operations.
Cosmic radiation - penetrating ionizing radiation originating from the sun and from outer space varying from altitude and latitude.
Curie (Ci) - the unit of radioactivity equal to 2.2 trillion disintegrations per minute.
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 dose (the unit of dose equivalent is the rem).
Ecology - a branch of biology dealing with the relations between organisms and their environment.
Electromagnetic radiation - a traveling wave motion resulting from changing electric or magnetic fields. Familiar sources of electromagnetic radiation range from x-rays (and gamma rays) of short wavelength, through the ultraviolet, visible and infrared regions, to radar and radio waves of relatively long wavelength. All electromagnetic radiation travels in a vacuum at the speed of light.
-- page 85 of 122 --
Element - one of 103 known chemical substances that cannot be broken down further without changing its chemical properties.
Environment - the aggregate of surrounding things, conditions, or influences.
Exposure - a measure of the ionization produced in air by x-ray or gamma radiation. Acute exposure is generally accepted to be large exposure received over a short period of time. Chronic exposure is exposure received over a long period of time.
Fission - process by which an atomic nucleus splits into two smaller nuclei and releases neutrons and energy.
Fission products - the nuclei formed as part of the fissioning of an atomic nucleus.
Gamma rays - high energy, short wavelength electromagnetic radiation emitted 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 Limit of Detection (LLD) - the smallest amount of sample activity that will give a net count for which there is a confidence at a predetermined level that the activity is actually present.
Microcurie (pCi) - 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.
Nucleus - the center of an atom containing protons and neutrons; determines the atomic weight and contributes to the net 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, and neutron) or waves (gamma).
Radionuclide - a radioactive species of an atom characterized by the constitution of its nucleus. The number of protons, number of neutrons, and energy content specify the nuclear constitution.
-- page 86 of 122 --
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.
Site boundary - the site boundary is the line beyond which the land is neither owned, nor leased, nor otherwise controlled by the licensee.
Statistics - the science that deals with the collection, classification, analysis and interpretation of numerical data by use of mathematical theories of probabilities.
Target tissue - any tissue or organ of the body in which radiation is absorbed.
Terrestrial radiation - source of radiation pertaining to the ground (Earth's crust).
X-rays - high energy, short wavelength electromagnetic radiation, emitted from the electron shells of an atom.

APPENDIX D Exceptions to the REMP During 2001 Data from the radiological analysis of environmental samples are routinely reviewed and evaluated by the Chemistry Department at the Clinton Power Station (CPS). This data is checked for LLD compliance, anomalous values, quality control sample agreement, and any positive results which are inconsistent with expected results - or - which exceed any Offsite Dose Calculation Manual (ODCM) reporting levels. Reporting levels for radioactivity concentrations from environmental samples are required by the CPS-ODCM and are listed in Table 3-A of this report.
If an inconsistent result occurs, an investigation is initiated which may consist of one, some, or all of the following actions:
Examine the collection data sheets for any indication of collection or delivery errors, tampering, vandalism, equipment calibration or any malfunction[s] as a result of electrical power failure[s], weather conditions, blown fuses, 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 Radiological Effluent Release Reports If possible, recount and / or reanalyze the sample Collect additional follow-up samples as warranted During 2001, no investigations were performed as a result of reaching any ODCM reporting levels. All sample analysis required by the ODCM achieved the LLDs specified by the CPS ODCM (refer to Table 3-B of this report). Sampling and analysis exceptions are listed in this appendix.

SAMPLING AND ANALYSIS EXCEPTIONS FOR 2001 The exceptions described in this section are those that are considered deviations from the Radiological Environmental Monitoring Program as required by the ODCM. This section addresses the reporting requirements of Section 7.1 of the ODCM.
[1] 28 March 2001 Although Surface Water Sample[s] CL-91 and CL-99 were properly collected, packaged and shipped to our Laboratory for analysis, both of these Water Samples were damaged during transit. Upon arrival at the Laboratory Facility, said samples arrived damaged [leaking] such that an adequate volume for analysis was not possible. CPS captured this event as part of their Corrective Actions Program under Condition Report Number 2-01-04-046.
[2] 28 November 2001
- Upon the weekly Air Sample / Filter Cartridge change-out at Air Sample Station CL-15, there was no electrical power. Additional testing at the station revealed that all electrical power was de-energized. After further troubleshooting, it was subsequently determined that a fuse had blown and was replaced. Because the minimum air volume was not obtained from this Air Sampling Station as a result of the blown fuse, this sample was not included in the 2001 Annual Report. CPS captured this event as part of their Corrective Actions Program under Condition Report Number 84348.
