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 1,1998 through December 31, 1998. This report includes a detailed meteorological section that 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 that 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 to maintain the amount of radioactive material in effluent releases to unrestricted areas As Low As Reasonably Achievable (ALARA). To assure these criteria are met, the NRC has established limits governing the release of radioactivity in effluents.

, CPS 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 vc. small. The radiation dose to people in the vicinity of CPS was calculated by using the concentra ion of radioactive nuclides in each release and the weather conditions at the time of the releus. The dose from CPS effluents was only a small fraction of the limit for the most exposed member of the public and came entirely from gaseous releases from the site. There were no liquid releases in 1998.

SECTION 2 l 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 generating unit was 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 I

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.

CPS releases airborne effluents via two gaseous effluent release points to the environment: the i Common Station Heating, Ventilating, and Air Conditioning (HVAC) Stack and the Standby Gas l 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.

CPS releases liquid effluents in the batch mode. Each release is sampled and analyzed prior to I I release. Liquid effluents, (variable from 10-60 gallons per minute (GPM) or 50 300 GPM depending upon the source of the discharge), combine with Plant Service Water flow (minimum of 1 approximately 5000 GPM) and Plant Circulating Water flow (0-567,000 GPM) in the seal well I prior to entering the 3.4 mile discharge flume to Lake Clinton (see Figure 2.)

Processine and Monitorine i

CPS strictly controls effluents to ensure radioactivity released to the environment is minimal and I'j does not exceed release limits. Effluent controls include the operation of radiation monitoring '

systems in the plant as well as offsite environmental sampling and analysis programs. In plant radiation monitoring systems are used to provide a continuous indication of radioactivity in effluent streams. Some are also used to collect particulate and radioiodine samples. Radioactive effluent related samples are analyzed in a laboratory to identify the specific concentration of l radionuclides being released. Sampling and analyses provide a more sensitive and precise method W of determining effluent composition to complement the information provided by real time j radiation monitoring instruments.

Beyond the plant itself, a Radiological Environmental Monitoring Program (REMP) is maintained )

in accordance with Federal Regulations. The basic purpose of the REMP pr'ogram is to assess the !

radiological impact on the environment due to the operation of the Clinton Power Station. 1 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 i program consists of two phases, pre-operational and operational. During the pre-operational !

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 gi verify that the in-plant controls for the release of radioactive material are functioning as designed. 5 Assessment of the operational impact of CPS on the environment is based on data collected since initial reactor criticality.

Exposure Pathways lladiological 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 how the plant environs are used (i.e., residence, gardens, etc.). 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 the release. This information is used to evaluate how the -

radionuclides will be distributed in the area. The most important factor in evaluating the q 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 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 J pathways include fish consumption and direct exposure from the lake.

Dose Assessment I

Whole body radiation involves the exposure of all organs in the human body to ionizing radiation. s Most background 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 bone.

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 short periods of time due to their rapid radioactive decay and/or elimination rate ,

from the body, while others may remain longer.

The radiation dose to people in the area surrounding CPS is 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 individual" 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.

Section 6 contains 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-131,1 133, 43, and all radionuclides in particulate form with half-lives greater than eight days. Noble gases, such as xenon and krypton, are biologically and chemically non-reactive; these radionuclides cause external radiation exposure.1-131, I-133, II-3, and radionuclides in particulate form with half-lives greater than eight days are the major contributors to internal dose.

9

Liauid Effluents Liquid effluents may come from two sources at CPS. The first source is effluent from the Radioactive Waste Treatment System. This water is demineralized prior to release. Samples are taken after the tank has been allowed to adequately recirculate. The second source is from heat exchanger leaks found in closed cooling water systems that service radioactively contaminated systems. These releases are considered abnormal releases. As a matter of commitment, CPS l

strives to be a zero-liquid discharge plant.

I 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 sbipped offsite for burial or disposal. To ensure that CPS is complying with these regulations, tue types of waste and the radioactivity present are reported to the NRC.

SECTION 3 SUPPLEMENTAL INFORMATION l

!I I. REGULATORY LIMITS

g The NRC requires nuclear power plants to be designed, constructed and operated in such a way l

'3 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 the Offsite Dose I Calculation Manual (ODCM) governing the release of radioactive effluents. The ODCM l designates 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. These limits are taken from Code of Federal

,g Regulations (CFR), Title 10, Part 50, Appendix I (10CFR50 Appendix I), Title 10 of the Code of

'3 Federal Regulations, Part 20 (10CFR20), and Title 10 of the Code of Federal Regulations, Part 20, l Appendix B, Table 2, Column 2. Keeping releases within these operating limits demonstrates i that the ALARA principle is being met. These ALARA limits are a fraction of the dose limits

'I' 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 l

i

<> nuclear power plant. These desc limits are: ;

8 -

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.

Less than or equal to 25 mrem per year to any other organ. I Specific limit information is given below.

A. Gaseous Effluents

1. In accordance with Title 10 of the Code of Federal Regulations (CFR), Part 20, the maximum permissible concentrations for gaseous effluents shall not exceed the values given in 10CFR20, Appendix B, Table 2, Column 1. To ensure these concentrations are not exceeded, dose rates due to radioactive materials released in gaseous offluents from the site to areas at and beyond the site boundary shall be limited to the following:

l a. Noble gases Less than or equal to 500 mrem / year to the total body.

I Less than or equal to 3000 mrem / year to the skin.

b. I 131, I-133, H 3, and all radionuclides in particulate brm with half-lives greater than eight days:

Less than or equal to 1500 mrem / year to any organ.

lg 12 I J

2. In accordance with Title 10 of the Code of Federal Regulations, Part 50, Appendix I, air dose dus to noble gr.scs released in gaseous effluents to areas at and beyond the site boundary shall be limited to the following:

a. Less than or equal to 5 mrad for gamma radiation and less than or equal to 10 mrad for beta radiation during any calendar quarter.

b. Less than or equal to 10 mrad for gamma radiation and less than or equal to 20 mrad for beta radiation during any calendar year.

3. In accordance with 10CFR50, Appendix I, dose to a member of the public (from 82I, j 1831,8H and all radionuclides in particulate form with half-lives greater than eight '

days) in gaseous effluents released to areas at and beyond the site boundary shall be limited to the following:

a. Less than or equal to 7.5 mrem to any organ, during any calendar quarter.

i

b. Less than or equal to 15 mrem to any organ, during any calendar year. J B. Liquid Effluents I'

1. The concentration of radioactive material released in liquid effluents to unrestricted J

areas shall be limited to the concentrations specified in Title 10 of the Code of q Federal Regulations, Part 20, Appendix B, Table 2, Column 2, for radionuclides !

other than dissolved or entrained noble gases. For dissolved or entrained noble !

gases, the concentration shall be limited to 2.0E-04 microcuries per milliliter total _j activity. I

2. The dose or dose commitment to a member of the public from radioactive materials I!.

in liquid effluents released to unrestricted areas shall be limited to: !

a. Less than or equal to 1.5 mrem to the total body and less than or equal to 5 I, mrem to any organ during any calendar quarter.

b. Less than or equal to 3 mrem to the total body and less than or equal to 10 mrem to any organ during any calendar year.

II. AVERAGE ENERGY Il '

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 E) concentrations in our effluent streams, and are not based upon gross count monitors. Therefore, W l the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide j 1.21, " Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of j Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power j Plants", are not applicable. l 13 I l e_

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 I 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 o 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 I 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.

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 I Each tank ofliquid radwaste is recirculated for at least 2 tank volumes, sampled, and analyzed for principal gamma emitters prior to release. Each sample tank is l recirculated for a sufficient amount of time prior to sampling to ensure that a representative sample is obtained. Samples are analyzed on an HPGe system and release permits are generated based on the values obtained from the isotopic analysis and the most recent values for 3H, gross alpha,55Fe,2Sr and *Sr. An aliquot based on release volume is saved and added to composite containers. The concentrations of composited isotopes and the volumes of the releases associated I with these composites establish the proportional relationships that are then utilized for calculating the total activity released for these isotopes.

SECTION 6 i DOSE MEASUREMENTS AND ASSESSMENTS This section of the Effluent Report provides the dose received by receptors around Clinton Power Station from gaseous and liquid effluents. The dose to the receptor that would have received the J

highest dose in each sector (defined as the Critical Receptor for that sector) is listed in this report.

This section also lists doses to individuals who used areas inside the Site Boundary. gA this section are the Thermoluminescent Dosimeter Readings from the various sites around the l plant to further document compliance with 40CFR190 requirements.

The assumptions used in determining dose values are as follows:

. All receptors within an 8 kilometer radius are included in the annual Land Use Census. This g census determines what dose pathways are present as well as the distance of each receptor from the site.

g!

. The annual average meteorological data for 1997 was used, in conjunction with the Land Use a Census is used to determine the dose to each receptor within 8 kilometers. g

. The doses for each receptor in each sector were determined using methodologies given in the ODCM.

. The activity used in these assessments is the total activity released by CPS for the year.

. The occupancy factor was taken into account when determining dose to individuals using areas inside the Site Boundary in non-residential areas. The occupancy factor is determined by dividing the number of hour of occupancy per year (taken from the ODCM) and dividing that value by the total number of hours per year.

. Dose to individuals using areas inside the Site Boundary (that are not residences) was calculated using the Ground Plane and Inhalation pathways.

DOSES TO MEMBERS OF THE PUBLIC WITHIN THE SITE BOUNDARY CPS Offsite Dose Calculation Manual section 7.2 requires that the Radioactive Effluent Release Report include an assessment of the radiation doses from radioactive liquids and gaseous effluents to MEMBERS OF THE PUBLIC due to their activities inside the SITE BOUNDARY. Within the CPS site boundary there are seven areas which are open to members of the public as identified by 3 CPS ODCM Table 3.4 4 (see Figure 4):

- The Department of Natural Resources Recreation Area at 1.287 kilometers I

(0.8 miles) in the ESE sector E A road at 0.495 kilometers (0.3 miles) in the SE sector g A residence at 2.736 kilometers (1.7 miles) in the SSE sector A residence at 1.219 kilometers (0.8 miles) in the SW sector 3

- Agricultural acreage at 1.372 kilometers (0.9 miles) in the SSW sector 3 A residence at 2.414 kilometers (1.5 miles) in the WSW sector A portion of Clinton Lake at 0.335 kilometers (0.2_ miles) in_the_,NW s,ector,_

At all of the above locations, the plume, inhalation and ground plane exposure pathways are used E '

for dose calculations. No other exposure pathways were identified by the 1998 Annual Land Use 3 Census. All dose calculations were performed using the methodology contained in the CPS ODCM. l l

SECTION 7 f 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 ofinstrumentation, 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 differential temperature between the 10 meter and.60-meter levels. Dew point is measured at the 10 meter level with an aspirated dew point sensor.

Meteorological monitoring instruments have been placed on the Clinton 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 Control Room via a dedicated telephone line. There the signals are received and converted to a 4 to 20 milliamp signal and fed indwidually 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 Cor L ei Room and the Technical Support Center.

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 release analysis procedures specified in Regulatory Guide 1.111. For joint frequency input data, periods of calm are distributed in accordance with a directional distribruon. For hourly input data, periods of calm are the previous hour's wind direction. Periods of odm are assigned a wind speed value of half the specified instrument threshold value. See Table 18 for more detailed information on meteorology and dispersion data.

1RIX-PR036 l On February 19,1998 the Plant Service Water Effluent Radiation Monitor, IRIX-PR036, was declared " INOPERABLE" due to a communication problem which resulted in " Transmit Time-out" 5j.'

alarms being received on the Central Control Terminal (CCT) in the Main Control Room (MCR).

When 1RIX-PR036 was declared " INOPERABLE", OOR 98 020 was entered and maintenance request D79360 was initiated. On February 20,1998, Maintenance Planning completed preparing the maintenance request. C&I Maintenance attempted to start troubleshooting the l communication problem associated with 1RIX-PR036 on February 25 and February 26,1998, but were not allowed, as the job was not scheduled for work on these dates.

On February 27,1998, C&I Maintenance commenced troubleshooting the communication problem associated with 1RIX-PR036. Initial troubleshooting revealed that the 5 volt DC signal (output of repeater IU.X PR060) only measured 2.5 volts DC. When an op amp was removed from the level shifter board in 1UX PR060, the 5 volt signal recovered, and communication between the MCR CCT and 1RIX-PR036 was reestablished. Communication was monitored between the MCR CCT and IRIX-PR036, from February 27th through March 2nd, with the op amp removed from the level shifter board, and no communication alarms were observed. On March 2nd a new op amp I was installed on the level shifter board in 1UX-PR060 and the voltage dropped to 2.7 volts DC. At u this time the entire repeater,1UX PR060, was removed from the field for testing / checkout.

Troubleshooting and circuit analysis was performed on March 3rd,4th,5th, and 6th but the g problem associated with the repeater could not be isolated. On March 7th a different repeater a was installed, on March 8th voltage checks on the replacement repeater were satisfactory.

Communication between the MCR CCT and IRIX-PR036 was then monitored from March 8th 3 through March 20th; no communication alarms were observed during this time frame. 5 On March 20th a high level TDR was performed on the communication lines between repeater B 1UX-PR060 and 1RIX-PR036. Results of this TDR did not show any degradation in the 5 communication lines but did show an irregularity approximately 40 feet from 1RIX PR036.

Inspection of the communication line on March 21st revealed a sharp bend approximately 40 feet g from 1RIX-PR036 where the communication line entered conduit CSWG020. Upon inspection of 5 the communication line it was determined that no rework was requirtu due to the sharp bend.

Communication between the MCR CCT and 1RIX-PR036 continued to monitored to ensure that g the communication problem did not reoccur. On March 24,1998, maintenance request D79360 g was closed out by C&I Maintenance and forwarded to Operations.

Communication was again monitored by Operations and when no failures were observed, IRIX-PR036 was returned to service and declared " OPERABLE" on April 6,1998. j I'

1RIX-PR036 On August 16, 1998 the Plant Service Water Effluent Radiation Monitor, IRIX-PR036, was declared inoperable again due to invalid External Fail, Alert, and High alarms being reported from the monitor. In addition, whenever a request for history was generated from the Main Control Room Central Control Terminal (MCR-CCT) for 1RIX-PR036, the MCR CCT would become " locked up". C&I Maintenance began troubleshooting radiation monitor 1RIX-PR036 on August 17,1998 under Maintenance Work Request (MWR) D86927.

On August 19, 1998 the Eberline Single Board Computer (ESBC) board and EPROMs were replaced in IRIX PR036 which resolved the problem associated with invalid alarms. The only problem remaining on August 20, 1998 was requesting historical information for 1RIX PR036 from the MCR-CCT. Due to previous problems associated with this monitor it was speculated that the historical request problem was with the communication line and not with 1RIX-PR036.

However, at this time it was not apparent whether the problem resided within the radiation monitor itself, (1RIX-PR036), or somewhere on the communication line between 1RIX-PR036 and the MCR-CCT. In order to determine wSther the problem resided in IRIX PR036 or the communication line, a portable Area Radiation Monitor (ARM) would be connected in place of 1RIX-PR036. If a historical data request of the portable ARM resulted in a MCR CCT " lock up" then the problem most likely was with the communication line, if no problems were noted when a historical information request was made of the portable ARM troubleshooting efforts would then be focused on 1RIX-PR036.

On August 27,1998 communication cables were fabricated in order to connect the portable ARM in place of 1RIX-PR036. On August 31,1998 the portable ARM was connected in place of IRIX.

PR036 and testing resulted in a MCR CCT " lock up" The portable ARM was disconnected and 3RIX-PR036 was reconnected to the communication line. Further troubleshooting efforts would be focused on the communication line between 1RIX-PR036 and the MCR-CCT. Troubleshooting was performed on Sept. lat, Sept. 2nd, Sept. 3rd, Sept. 4th, Sept, 6th, Sept, 9th, and Sept.10th. On Sept. lith it was determined that 4 capacitors in repeater IUX PR060 needed replaced.

Capacitors were ordered on Sept.14th and received on Sept.17th, troub}cshooting continued on Sept.18th. Replacement of capacitors on Sept.18th [gjjed to resolve problem, problem was isolated to an op amp on the level shifter board in repeater IUX-PR000. When this op amp was installed, a historical request of 1RIX-PR036 or any other monitor downstream of repeater IUX PR060 resulted in a MCR-CCT " lock up". When the op amp was removed ' rom the level shifter board, no problems were noted when a historical request was generated on any monitor downstream of repeater IUX-PR060. Replacement of this op amp on the level shifter board in repeater IUX-PR060 yielded the same results.

l Since the op amp on the level shifter board provides qualitative indication on the board that communication is occurring and has no active function in the transmission of data it was decided to remove the op amp from the circuit via a temporary modification. This would allow further troubleshooting in the future and allow 1RIX-PR036 to be returned to service. On Sept. 24th a channel functional test (CPS No. 9537.62) was successfully completed on 1RIX PR036 with the op amp removed from the level shifter board. On Sept. 25th, temporary modif5Calidn 98 077 was installed to document the removal of the op amp from the level shifter board in 1UX-PR060 and MWR D86927 was forwarded to Operations for review.

1 On or around October 5,1998 the MCR declared IRIX PR036 " OPERABLE" in accordance with ODCM Table 2.7-1, remedial requirement number 2.a. This remedial requirement was entered as it was evident that there was no problem associated with the capability of the 1RIX-PR036 to measure radioactivity but an insufficient amount of time had clapsed to ensure that the communication issue was resolved by temporary modification 98-077. On or around December 18, 1998 it was determined that sufficient time had passed to show that reliable communications had been established between the MCR CCT and radiation monitor IRIX-PR036 with temporary modification 98 077 and remedial requirement number 2.a of ODCM Table 2.7-1 for 1RIX PR036 was exited. The communication problem between 1RIX PR036 and the MCR CCT, with the op amp installed on the level shifter board in repeater IUX PR060, continues to be evaluated. .
