SUMMARY

The Annual Radioactive Effluent Release Report is a detailed description of all radioactive releases (both gaseous and liquid) from the Clinton Power Station (CPS) and the resulting radiation doses for the period from January 1, 1995 through December 31, 1995. This report includes a detailed meteorological section which provides the weather history of the area during this period. This information is used to calculate the dose to the public.

The report also includes a summary of the amounts of radioactive material contained in solid waste that is packaged and shipped for

~

offsite disposal at federally-approved burial facilities. In addition, this report notifies the U.S. Nuclear Regulatory Commission (NRC) staff of changes to CPS's Offsite Dose Calculation Manual (ODCM) and exceptions to the CPS effluent monitoring program which must be reported per ODCM Operation Requirements 2.7.1.b and 3.9.2.b.

The NRC requires that nuclear power stations be designed, constructed, and operated in such a way that the amount of radioactive material in effluent releases to unrestricted areas is kept As Low As Seasonably Achievable (ALARA). To assure these criteria are met, the NRC has established limits governing the release of radioactivity in effluents.

CPS was operated in compliance with established limits during-this report period. The maximum radiation dose delivered to the inhabitants of the area surrounding CPS, due to radioactivity released from the station, was very small. The radiation dose to people in the vicinity of CPS was calculated for a continuous gaseous release by using the concentration of radioactive material and the weather conditions at the time of the release. This dose was only a small fraction of the limit for the most exposed member of the public. CPS did not have any liquid radioactive releases in 1995.

SECTION 2 INTRODUCTION Clinton Power Station is located in Harp Township, DeWitt County approximately six miles east of the city of Clinton in east-central Illinois. Clinton Power Station is a 985 megawatt gross electrical power output boiling water reactor. The reactor and generating units were supplied by General Electric, Sargent and Lundy Engineers served as architect-engineer, and Baldwin Associates was the constructor.

Construction of CPS began in the mid 1970's. Fuel load began in September of 1986 with initial criticality achieved on February 27, 1987. Commercial operation commenced in April 1987 and the reactor reached 100% power for the first time on September 15, 1987.

Airborne effluents are released from CPS via two gaseous effluent release points to the environment: the Common Station Heating, Ventilating, and Air Conditioning (HVAC) Stack and the Standby Gas Treatment System (SGTS) Vent (see Figure 1). Each release point is continuously monitored and a program of periodic sampling and analysis is conducted as specified in the ODCM.

Liquid effluents from CPS are released in batch mode and are sampled and analyzed prior to release. Liquid effluents, (variable from 10-60 gallons per minute (GPM) or 50-300 GPM), combine with Plant Service Water flow (minimum of approximately 5000 GPM) and Plant Circulating Water flow (0-567,000 GPM) in the seal well prior to entering the 3.4 mile discharge flume to Lake Clinton (see Figure 2).

Regulatory Limits The NRC requires nuclear power plants to be designed, constructed and operated in such a way that the radioactivity in effluent releases to unrestricted areas is kept ALARA. To assure these criteria are met, each license authorizing nuclear reactor operation includes Radiological Effluent Technical Specifications (RETS) governing the release of radioactive effluents (Code of Federal Regulations, Title 10, Part 50, Appendix I). The RETS designate the limits for release of effluents, as well as the limits for doses to the general public from the release of radioactive liquids and gases. Keeping releases within these operating limits demonstrates that the ALARA principle is being met.

The dose to a member of the general public from radioactive material in liquid effluents released to unrestricted areas is limited to:

Less than or equal to 3 mrem per year to the total body.

-and-Less than or equal to 10 mrem per year to any organ.

The dose to a member of the general public from the release of noble gases in gaseous effluents is limited to:

Less than or equal to 10 mrad per year for gamma radiation.

-and-Less than or equal to 20 mrad per year for beta radiation.

The dose to a member of the general public from iodine-131, tritium and all particulate radionuclides with a half-life greater than eight days in gaseous effluents is limited to:

Less than or equal to 15 mrem per year to any organ.

These ALARA limits are a fraction of the dose limits established by the Environmental Protection Agency (EPA). In its Environmental Dose Standard of 40CFR190, the EPA established dose limits for members of the public in the vicinity of a nuclear power plant. These dose limits are:

Less than or equal to 25 mrem per year to the total body.

Less than or equal to 75 mrem per year to the thyroid.

-and-Less than or equal to 25 mrem per year to any other i organ.  ;

Processing and Monitoring i l

i Effluents are strictly controlled at CPS to ensure radioactivity released to the environment is minimal and does not exceed release limits. Effluent controls include the operation of radiation l monitoring systems in the plant and offsite environmental sampling and j analysis programs. In-plant radiation monitoring systems are used to provide a continuous indication of radioactivity and are also used to l collect particulate and radioiodine samples. These samples are l analyzed in a laboratory to identify the specific concentration of l radionuclides being released. Sampling and analysis provide a more sensitive and precise method of determining effluent composition to '

complement the information provided by real-time monitoring instruments. I Beyond the plant itself, a radiological environmental monitoring i program is maintained in accordance with Federal Regulations. The {

basic purpose of the program is to assess the radiological impact on '

the environment due to the operation of the Clinton Power Station. l Implicit in this purpose is the regulatory requirement to trend and assess radiation exposure rates and radioactivity concentrations that may contribute to human radiation exposure. The program consists of two phases, preoperational and operational. During the preoperational

! phase of the program, the baseline for the local radiation environment was established. The operational phase of the program includes the objective of making confirmatory measurements to verify that the in-plant controls for the release of radioactive material are functioning as designed. Assessment of the operational impact of CPS on the environment is based on data collected since initial reactor criticality.

Exposure Pathways Radiological exposure pathways are the means by which people may become exposed to radioactivity released from nuclear facilities. The major pathways of concern are those which could cause the highest calculated radiation dose. These pathways are determined from the type and amount of radioactivity released, the environmental transport mechanism and use of the environment. The environmental transport mechanism includes the meteorological characteristics of the area which will be defined by wind speed and wind direction at the time of l the release. This information is used to evaluate how the radionuclides will be distributed in the area. The most important factor in evaluating the exposure pathway is the use of the environment by the people living around CPS. Factors such as location of homes in the area, use of cattle for milk and meat, and the growing of gardens for vegetable consumption are very important considerations 12 l

i in evaluating exposure pathways. Figure 3 illustrates the various effluent exposure pathways considered.

The radioactive gaseous effluent exposure pathways include direct radiation, deposition on plants and soil, and inhalation by animals and humans'. The radioactive liquid effluent exposure pathways include fish consumption and direct exposure from the lake.

Dose Assessment Whole body radiation involves the exposure of all organs in the human body to ionizing radiation. Most oackground radiation exposures  ;

consist of whole body exposure although specific organs can receive radiation exposure from distinct radionuclides. These radionuclides enter the body through inhalation-and ingestion and seek different organs depending on the nuclide. For example, radioactive iodine selectively concentrates in the thyroid, radioactive cesium collects  !

in muscle and liver tissue, and radioactive strontium in mineralized i bone.

i The total dose to organs from a given radionuclide also depends on the amount of activity in the organ and the amount of time that the radionuclide remains in the. body. Some radionuclides remain for very j short periods of time due to their rapid radioactive decay and/or j elimination rate from the body, while.others may remain longer.

The radiation dose to people in the area surrounding CPS is i calculated for each release using the concentrations of radioactive material and the weather conditions present at the time of the release. The dose is calculated in all sixteen geographical sectors surrounding CPS and takes into account the location of the nearest residents, vegetable gardens producing broad leaf vegetables, dairy and meat animals in all sectors. The calculated dose also uses the concept of a " maximum exposed individun1" and " standard man", and the maximum use factors for the environment, such as how much milk an average person drinks and how much air that person breathes in a year. l i

See Tables 11-18 of Section 6 for more detailed information on dose to the public. )

Gaseous Effluents Gaseous effluent radioactivity released from CPS is classified into two categories, 1) noble gases, and 2) "'I, *"I, 'H and all radionuclides in particulate form with half-lives greater than eight days. Noble gases, such as xenon and krypton, are biologically and chemically nonreactive; these radionuclides cause external radiation exposure. "'I, *"I, 'H and radionuclides in particulate form with half-lives greater than eight days are the major contributors to internal dose.

See Tables 1, 2, and 3 of Section 4 for more detailed information on gaseous effluents.

Liquid Effluents CPS had no radioactive liquid discharges in 1995.

Solid Waste Shipments In order to reduce the radiation exposure to personnel and maintain the ALARA concept, the NRC and the Department of Transportation (DOT) have established limits on the types of radioactive waste and the amount of radioactivity that may be packaged and shipped offsite for burial or disposal. To ensure that CPS is complying with these regulations, the types of waste and the radioactivity present are reported to the NRC.

See Table 7 of Section 4 for more detailed information on solid waste shipments.

II. AVERAGE ENERGY The CPS ODCM limits the dose equivalent rates due to the release of fission and activation gases to less than or equal to 500 mrem per year to the total body and less than or equal to 3000 mrem per year to the skin. These limits are based on dose calculations using actual isotopic concentrations in our effluent streams, and are not based upon gross count monitors. Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21, " Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants", are not applicable.

III. MEASUREMENT AND APPROXIMATIONS OF TOTAL RADIOACTIVITY A. Fission and Activation Gases

1. Gas samples are collected weekly and are counted on a high purity germanium detector (HPGe) for principal gamma emitters. The HVAC and SGTS release points are continuously monitored, and the average release flow rates for each release point are used to calculate the total activity released in a given time period.
2. Tritium is collected by passing a known volume of the sample stream through a gas washer containing a known quantity of demineralized water. The collected samples are distilled and analyzed by liquid scintillation. The tritium released was calculated for each release point from the measured tritium concentration, the volume of the sample, the tritium collection efficiency, and the stack exhaust flow rates.

B. Iodines Iodine is continuously collected on a charcoal cartridge filter via an isokinetic sampling assembly on each release point. Filters are normally exchanged once per week and analyzed on an HPGe system. The daily average flow rates for each release point are averaged for the duration of the sampling period and these results, along with isotopic concentrations, are used to determine total activity released during the time period in question.

18

(

4 C. Particulates

-Particulates are continuously collected on a filter paper via an isokinetic sampling assembly on each release point. Filters are normally exchanged once per week and analyzed on an HPGe system. Flow rates and total activity are determined in the same manner as for iodines.

D. Liquid Effluents Each tank of liquid radwaste is sampled and analyzed for principal gamma emitters prior to release. Each i sample tank is recirculated for a sufficient amount of' time prior to sampling to ensure that a representative  ;

sample is obtained. Samples are analyzed on an HPGe l system and release permits are generated based on the values obtained from the isotopic analysis and the most recent values for 'H, gross alpha, 55 Fe, "Sr and "Sr.

An aliquot based on release volume is saved and added i to composite containers. The concentrations of composited isotopes and the volumes of the releases associated with these composites establish the l proportional relationships that are then utilized for calculating the total activity released for these isotopes.

In 1995 there were no liquid batch releases.

Table 6 Notations (Cont'd)

Where:

LLD is the "a priori" lower limit of detection as defined above, as microcuries per unit mass.or volume, sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, V is the sample size in units of mass or volume,

2.22 x 106 is the number of disintegrations per minute per microcurie, Y is the fractional radiochemical yield, when applicable, A is the radioactive decay constant for the particular radionuclide (sec-1) and Ae for plant effluents is the elapsed time between the midpoint of sample collection and the time of counting (sec).

Typical values of E, V, Y, and At should be used in the calculation.

It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact, MDA) limit for a particular measurement.

b The principal gamma emitters for which the LLD requirement applies include the following radionuclides: "Mn, "Fe, "Co , "Co, " Zn , "Mo,

    • Cs, *"Cs, and "*Ce. *"Ce shall also be measured, but with an LLD of 5 x 10-6 This list does not mean that only these nuclides are to be detected and reported. Other gamma peaks that are measurable, together with those of the above nuclides, shall also be analyzed and reported in the Radioactive Effluent Release Report.

I SECTION 5 METEOROLOGICAL DATA AND DISPERSION ESTIMATES i

The meteorological monitoring program began at the Clinton Power

! Station site on April 13, 1972. The meteorological system consists of

, a tower 199 feet high with two levels of instrumentation, at the 10-meter and 60-meter levels. Wind directions and speeds at the 10-meter and 60-meter levels are measured by a combined cup and vane sensor.

The temperature at these levels is sensed by an aspirated dual temperature sensor. One-half of the dual sensor at each elevation is used for ambient temperature while the other half is used to provide a j differential temperature between the 10-meter and 60-meter levels.

Dow-point is measured at the 10-meter level with an aspirated dew-

< point sensor.

Meteorological monitoring instruments have been placed on the Clinton j Power Station microwave tower at the 10-meter level to act as a backup to the existing meteorological tower.

Clinton Power Station meteorological data is transmitted to the Main 3

Control Room via a dedicated telephone line. There the signals are received and converted to a 4 to 20 milliamp signal and fed 4

individually to a microprocessor and chart recorders. The microprocessor is part of the Clinton Power Station Radiation Monitoring System. Meteorological data is available via the microprocessors in the Main Control Room, Technical Support Center and i I

Radiation Protection office.

Dispersion modeling for effluents for normal operation of Clinton Power Station is a straight-line, sector-averaged Gaussian plume model designed to estimate average relative concentration at various receptor points. The model was developed in accordance with routine 4

release analysis procedures specified in Regulatory Guide 1.111. For joint frequency input data, periods of calm are distributed in accordance with a directional distribution. For hourly input data, periods of calm are assigned the previous hour's wind direction.

Periods of calm are assigned a wind speed value of half the specified instrument threshold value. See Table 10 for more detailed information on meteorology and dispersion data.
