==SUMMARY==
The Annual Radioactive Effluent Release Report (ARERR) is a detailed description of gaseous and liquid radioactive effluents released from Clinton Power Station (CPS) and the resulting radiation doses for the period of January 01, 2016 through December, 31 2016. This report also includes a detailed meteorological section providing weather history of the surrounding area during this period. The information in the ARERR is used to calculate the offsite dose to our public. The report also includes a summary of the amounts of radioactive material contained in solid waste that is packaged and shipped to a federally approved disposal/burial facility offsite. Additionally, this report notifies the U.S. Nuclear Regulatory Commission (NRC) staff of changes to CPS's Offsite Dose Calculation Manual (ODCM), as well as exceptions to the CPS effluent monitoring program and a summary of events that must be reported in accordance with ODCM Remedial Requirements 3.1.1 Action G and 3.2.2 Action G. The NRC requires that nuclear power facilities be designed, constructed and operated in such a manner as to maintain radioactive effluent releases to unrestricted areas f:ls !:_ow f:ls .B.easonably f:lchievable (ALARA). To ensure compliance with this criterion, the NRC has established limitations governing the release of radioactivity in effluents.
 
During 2016, CPS operations were well within these federally required limits. The maximum annual radiation dose delivered to the inhabitants of the area surrounding CPS, due to radioactivity released from the station, was 5.66E-02mrem (milliroentgen).
The Annual Radioactive Effluent Release Report (ARERR) is a detailed description of gaseous and liquid radioactive effluents released from Clinton Power Station (CPS) and the resulting radiation doses for the period of January 01, 2016 through December, 31 2016. This report also includes a detailed meteorological section providing weather history of the surrounding area during this period. The information in the ARERR is used to calculate the offsite dose to our public.
The radiation dose to the public in the vicinity of CPS was calculated by using the concentration of radioactive nuclides from each gaseous effluent release coupled with historical weather conditions.
The report also includes a summary of the amounts of radioactive material contained in solid waste that is packaged and shipped to a federally approved disposal/burial facility offsite. Additionally, this report notifies the U.S. Nuclear Regulatory Commission (NRC) staff of changes to CPS's Offsite Dose Calculation Manual (ODCM), as well as exceptions to the CPS effluent monitoring program and a summary of events that must be reported in accordance with ODCM Remedial Requirements 3.1.1 Action G and 3.2.2 Action G.
The dose from CPS gaseous radioactive effluents was only a small fraction of the limit for the maximum exposed member of the public. There were no liquid effluent releases in 2016. As such, there was. no dose received by the public from the liquid radioactive effluent pathway. Page 5of162 SECTION 2 INTRODUCTION CPS is located in Harp Township, DeWitt County approximately six miles east of the city of Clinton in east-central Illinois.

CPS is a megawatt gross electrical power output boiling water reactor. Initial fuel load commenced in September of 1986 with initial criticality of the reactor occurring 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.
.B.easonably f:lchievable (ALARA). To ensure compliance with this criterion, the NRC has established limitations governing the release of radioactivity in effluents.
They are the Common Station Heating, Ventilating, and Air Conditioning (HVAC) Vent and the Standby Gas Treatment System {SGTS) Vent as shown in Figure 1. Each gaseous effluent release point is continuously monitored consisting of a surveillance program of periodic sampling and analysis as specified in the ODCM. CPS is licensed to release radioactive liquid effluents in a batch mode, however there were no radioactive liquid releases in 2016 at CPS. Each release would have been sampled and analyzed prior to release if this were to occur. Depending upon the amount of activity in a release, liquid effluents would vary from 10 to 300 gallons per minute (GPM). This volume is further combined with both Plant Service Water flow, which is a minimum of approximately 5,000 GPM, along with Plant Circulating Water flow, another 0 to 567,000 GPM, in the seal well, just prior to entering the 3.4 mile discharge flume into Lake Clinton as demonstrated in Figure 2. Processing and Monitoring CPS strictly controls effluents to ensure radioactivity released to the environment is maintained ALARA and does not exceed federal release limit criteria.
During 2016, CPS operations were well within these federally required limits. The maximum annual radiation dose delivered to the inhabitants of the area surrounding CPS, due to radioactivity released from the station, was 5.66E-02mrem (milliroentgen). The radiation dose to the public in the vicinity of CPS was calculated by using the concentration of radioactive nuclides from each gaseous effluent release coupled with historical weather conditions.

As such, there was. no dose received by the public from the liquid radioactive effluent pathway.
Effluent controls include the operation of radiation monitoring systems within the plant as well as an offsite environmental analysis program. 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 controlled laboratory environment to identify the specific concentration of those radionuclides being released.

SECTION 2 INTRODUCTION CPS is located in Harp Township, DeWitt County approximately six miles east of the city of Clinton in east-central Illinois. CPS is a ~1,140 megawatt gross electrical power output boiling water reactor. Initial fuel load commenced in September of 1986 with initial criticality of the reactor occurring on February 27, 1987. Commercial operation commenced in April 1987 and the reactor reached 100% power for the first time on September 15, 1987.
Beyond the plant itself, a Radiological Environmental Monitoring Program (REMP) is maintained in accordance with Federal Regulations.
CPS releases airborne effluents via two gaseous effluent release points to the environment. They are the Common Station Heating, Ventilating, and Air Conditioning (HVAC)
The purpose of the REMP program is to the radiological impact on the environment due to operation of CPS. Implicit in this charter is the license requirement to trend and assess radiation exposure rates and radioactivity concentrations that may contribute to dose to the public. The program consists of two phases; pre-operational and operational.
Vent and the Standby Gas Treatment System {SGTS) Vent as shown in Figure 1. Each gaseous effluent release point is continuously monitored consisting of a surveillance program of periodic sampling and analysis as specified in the ODCM.
During the pre-operational phase of the program, the baseline for the local radiation environment was established.
CPS is licensed to release radioactive liquid effluents in a batch mode, however there were no radioactive liquid releases in 2016 at CPS. Each release would have been sampled and analyzed prior to release if this were to occur. Depending upon the amount of activity in a release, liquid effluents would vary from 10 to 300 gallons per minute (GPM). This volume is further combined with both Plant Service Water flow, which is a minimum of approximately 5,000 GPM, along with Plant Circulating Water flow, another 0 to 567,000 GPM, in the seal well, just prior to entering the 3.4 mile discharge flume into Lake Clinton as demonstrated in Figure 2.
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.

The major pathways of concern are those that 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 i ncludes the historical meteorological characteristics of the area that are defined by wind speed and wind direction. This information is used to evaluate how the radionuclides will be distributed within the surrounding area. The most important factor in evaluating the exposure pathway is the use of the environment by the public living around CPS. Factors such as location of homes in the area , use of cattle for milk and the growing of gardens for vegetable consumption are important considerations when evaluating exposu r e pathways. Figure 3 illustrates the effluent exposure pathways that were 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 e x posure pathways include fish consumption and direct exposure from Clinton Lake. Dose Assessment Whole body radiation invo l ves the exposure of all organs in the human body to ionizing radiation. Most naturally occurring 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 rad i onuclide remains in the body. Some radionucl i des 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. Radiation dose to the public in the area surrounding CPS is calculated for each release using historical weather conditions coupled with the concentrations of radioactive material present. The dose is calculated for all sixteen geographical sectors surrounding CPS and includes the location of the nearest residents, vegetable gardens producing broad leaf vegetables and dairy animals in all sectors. The calculated dose also uses the scientific concept of a "maximum exposed incjividual" and "standard man", and the maximum use fac t ors for the environment, such as how much milk an average person consumes and how much air a person breathes in a year. Section 6 contains more detailed information on dose to the public.

Ten (10) times the values found in 10CFR20 Appendix B, Table 2, Column 1 are used for all Effluent Concentration Limit (ECL) calculations. For dissolved and entrained noble gases, the concentration is limited to 2.00E-04 &#xb5;Ci/cc total activity.
[2)
The lower the value of the actual sample activity - with respect to background activity
      - the greater the counting error. Proportionally, large errors are reported for the various components of CPS gaseous effluents because of their consistent low sample activity.
An entry of O.OOE+Ol indicates that the Minimum Detectable Activity (MDA) concentration of the radionuclide was below the LLD value listed in Table 3.

SUMMARY

The Annual Radioactive Effluent Release Report (ARERR) is a detailed description of gaseous and liquid radioactive effluents released from Clinton Power Station (CPS) and the resulting radiation doses for the period of January 01, 2016 through December, 31 2016. This report also includes a detailed meteorological section providing weather history of the surrounding area during this period. The information in the ARERR is used to calculate the offsite dose to our public.

The report also includes a summary of the amounts of radioactive material contained in solid waste that is packaged and shipped to a federally approved disposal/burial facility offsite. Additionally, this report notifies the U.S. Nuclear Regulatory Commission (NRC) staff of changes to CPS's Offsite Dose Calculation Manual (ODCM), as well as exceptions to the CPS effluent monitoring program and a summary of events that must be reported in accordance with ODCM Remedial Requirements 3.1.1 Action G and 3.2.2 Action G.

The NRC requires that nuclear power facilities be designed, constructed and operated in such a manner as to maintain radioactive effluent releases to unrestricted areas f:ls !:_ow f:ls

.B.easonably f:lchievable (ALARA). To ensure compliance with this criterion, the NRC has established limitations governing the release of radioactivity in effluents.

During 2016, CPS operations were well within these federally required limits. The maximum annual radiation dose delivered to the inhabitants of the area surrounding CPS, due to radioactivity released from the station, was 5.66E-02mrem (milliroentgen). The radiation dose to the public in the vicinity of CPS was calculated by using the concentration of radioactive nuclides from each gaseous effluent release coupled with historical weather conditions. The dose from CPS gaseous radioactive effluents was only a small fraction of the limit for the maximum exposed member of the public. There were no liquid effluent releases in 2016. As such, there was. no dose received by the public from the liquid radioactive effluent pathway.

SECTION 2 INTRODUCTION CPS is located in Harp Township, DeWitt County approximately six miles east of the city of Clinton in east-central Illinois. CPS is a ~1,140 megawatt gross electrical power output boiling water reactor. Initial fuel load commenced in September of 1986 with initial criticality of the reactor occurring 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. They are the Common Station Heating, Ventilating, and Air Conditioning (HVAC)

Vent and the Standby Gas Treatment System {SGTS) Vent as shown in Figure 1. Each gaseous effluent release point is continuously monitored consisting of a surveillance program of periodic sampling and analysis as specified in the ODCM.

CPS is licensed to release radioactive liquid effluents in a batch mode, however there were no radioactive liquid releases in 2016 at CPS. Each release would have been sampled and analyzed prior to release if this were to occur. Depending upon the amount of activity in a release, liquid effluents would vary from 10 to 300 gallons per minute (GPM). This volume is further combined with both Plant Service Water flow, which is a minimum of approximately 5,000 GPM, along with Plant Circulating Water flow, another 0 to 567,000 GPM, in the seal well, just prior to entering the 3.4 mile discharge flume into Lake Clinton as demonstrated in Figure 2.

Processing and Monitoring CPS strictly controls effluents to ensure radioactivity released to the environment is maintained ALARA and does not exceed federal release limit criteria. Effluent controls include the operation of radiation monitoring systems within the plant as well as an offsite environmental analysis program. 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 controlled laboratory environment to identify the specific concentration of those radionuclides being released. Sampling and analysis provides. for a more sensitive and precise method of determining effluent composition to complement the information provided by real-time radiation monitoring instruments.

Beyond the plant itself, a Radiological Environmental Monitoring Program (REMP) is maintained in accordance with Federal Regulations. The purpose of the REMP program is to ass~ss the radiological impact on the environment due to t~e operation of CPS. Implicit in this charter is the license requirement to trend and assess radiation exposure rates and radioactivity concentrations that may contribute to dose to the public. The 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 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 criticality of the reactor.

Exposure Pathways A radiological exposure pathway is the vehicle by which the public may becom e exposed to radioactivity released from nuclear facilities . The major pathways of concern are those that 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 historical meteorological characteristics of the area that are defined by wind speed and wind direction . This information is used to evaluate how the radionuclides will be distributed within the surrounding area . The most important factor in evaluating the exposure pathway is the use of the environment by the public living around CPS . Factors such as location of homes in the area , use of cattle for milk and the growing of gardens for vegetable consumption are important considerations when evaluating exposu re pathways . Figure 3 illustrates the effluent exposure pathways that were 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 Clinton Lake.

Dose Assessment Whole body radiation invo lves the exposure of all organs in the human body to ionizing radiation . Most naturally occurring 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 rad ionuclide remains in the body . Some radionucl ides 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.

Radiation dose to the public in the area surrounding CPS is calculated for each release using historical weather conditions coupled with the concentrations of radioactive material present . The dose is calculated for all sixteen geographical sectors surrounding CPS and includes the location of the nearest residents, vegetable gardens producing broad leaf vegetables and dairy animals in all sectors . The calculated dose also uses the scientific concept of a "maximum exposed incjividual " and "standard man", and the maximum use fac t ors for the environment, such as how much milk an average person consumes and how much air a person breathes in a year .

Section 6 contains more detailed information on dose to the public.

I Gaseous Effluents Gaseous effluent radioactivity released from CPS is classified into two (2) categories.

131 133 3 14 The first category is noble gases. The second category consists of 1 , 1 , H , C and all radionuclides in particulate form with radioactive half-lives greater than eight (8) days. Noble gases - such as xenon and krypton - are biologically and chemically non-reactive. As such,

  • 85 133 135 these radionuclides - specifically Kr 111, Xe and Xe - are the *major contributors to external 31 133 3 14 doses. Halogens*l; and 1 , H 1 C and radionuClides ir\ particulate form *with radioactive half-lives greater than eight (8) days are the major eontributors to internal doses.

Liquid 6ffluents Liquid effluents may originate from two (i) sour'ces at CPS. The first is effluent from

  • the Radioactive Waste Treatment System. This water is demineralized prior to release.
  • Sam.pies *C:ii'e taken after the tank has been allowed to adeq1.fateiy recirculate. The second is from heat exchanger leaks found in closed cooling wat'er systems that service radioactively*

contamfnated systems. Th'fs wduld be considered an ~bnorinal release. As a*:matter of station manag*ement commitment, CPS strives to be a zero (0) radici:attiVe liquid release plant. The last liquid release occurred in September of 1992.

Solid Waste Shipments To reduce the radiation exposure to personnel and maintain the federally required ALARA concept, the NRC arid the Department of Transportation*(oOT) have'establ.ished 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 regu*lations, the types of waste and the radioactivity present are reported to the NRC.

SECTION 3 SUPPLEMENTAL INFORMATION I. REGULATORY LIMITS The NRC requires nuclear power facilities to be designed, constructed and operated in such a way that the radioactivity in effluent releases to unrestricted areas is kept ALARA. To ensure these criteria are met, each license authorizing nuclear reactor operation includes the Offsite Dose Calculation Manual governing the release of radioactive effluents. The ODCM 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 Title :10 of the Code of Federal Regulations, Part 50, Appendix I (10CFR50 Appendix I), Title 10 of the Code of Federal Regulations, Part 20.1301 (10CFR20.1301} and Section 5.5.4 of our Station's Technical Specifications. Maintaining effluent releases within these operating limitations demonstrates compliance with ALARA principles. These limits are just a fraction of the dose limits established by the Environmental Protection Agency (EPA) found within Environmental Dose Standard Title 40, Code of Federal Regulations, Part 190 (40CFR190). The EPA has 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.

Less than or equal to 25 mRem per year to any other organ.

Specific limit information is given below.

A.. Gaseous Effluents

1. The maximum permissible concentrations to limit doses for gaseous effluents shall not exceed the values provided within Section 5.5.4.g of Station Technical Specifications. To ensure these concentrations are not exceeded, dose rates due to radioactive materials released in gaseous effluents from the site to areas at and beyond the site area boundary shall be limited to the following:
a. Noble gases Le.ss than or equal to 500 mRem/year to the total body.

Less than or equal to 3,000 mRem/year to the skin.

131 133 3 14

b. 1 , 1 , H , C , and all radionuclides in particulate form with radioactive half-lives greater than eight (8) days:

Less than or equal to 1,500 mRem/year to any organ.

Page 12 of 162

2. In accordance with Title 10 of. the Code of Federal Regulations, Part 50, Appendix I, (10CFR50 Appendix I) air dose due to noble gases 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 m*Rad 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 Title 10 of the Code of Federal Regulations, Part 50, 131 Appendix I, (10CFRSO Appendix I), dose to a member of the public (from 1 ,

133 3 14 1 , H , C , and all radionuclides in* particulate form with radioactive half-lives greater than eight (8) days) in gaseous effluents released to areas at and beyond the site boundary shall be limited to the following values:

a. Less than or equal to 7.5 mRem to any organ, during any calendar quarter.
b. Less than or equal to 15 mRem to any organ, during any calendar year.

B. Liquid Effluents

1. The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to the values provided within Section 5.5.4.b of Station Technical Specifications for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-04 µCi/ml total activity.
2. The dose or dose commitment to a member of the public from radioactive materials in liquid effluents rel.eased 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 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 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 3,000 mRem per year to the skin. These limits are based on dose calculations using actual isotopic concentrations from our effluent release streams and not based upon the gross count rate from our monitoring systems. Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21, "Measuring, Evaluating, and

Ill. 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 during a given time period.
2. Tritium is also 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 respective stack exhaust flow rates.
3. Carbon-14 release values were estimated using the methodology included in the EPRI Technical Report 1021106, using the 2016 Clinton Power Station specific parameters of normalized Carbon-14 production rate of 5.049 Ci/GWt-yr, a gaseous release fraction of 0.99, a Carbon-14 carbon dioxide fraction of 0.95, a reactor power rating of 3473 MWt, and equivalent full power operation of 342.23days.

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

D. Liquid Effluents Page 14 of 162

Each tank of liquid radwaste is recirculat~d 'for at least two (2) tank volumes, sampled and analyzed for principal gamma emitters prior to release. Each sample tank is recirculated for a sufficient amount of time prfor to sampling en;surihg '.that a representative sample is obtained. Samples are then analyzed on an HPGe system and liquid release permits are generated based upon the val1,1es obtained frorii the isotopic analysis and the most recent 3 . 55 . . 89 . 90 . . . . . .

values for H , gross alpha, Fe , Sr arid Sr . An aliquot based on fe1¢ase volume is saved and added to composite containers. The concentrations of compo~lted isotopes and the volumes of the re!eases associated with these composites establish the proportional relationships that are the*n utilized f~:wcalcu_lating the total actiyity rel.eased for thesf7 isotpp'es.

IV. DESCRIPTION OF ERROR ESTIMATES Estimates of m.easurement and analytical error for gaseous and liquid effluents are calculated as follows:

Ten (10) times the values found in 10CFR20 Appendix B, Table 2, Column 1 are used for all Effluent Concentration Limit (ECL) calculations. For dissolved and entrained noble gases, the concentration is limited to 2.00E-04 µCi/cc total activity.

[2)

The lower the value of the actual sample activity - with respect to background activity

- the greater the counting error. Proportionally, large errors are reported for the various components of CPS gaseous effluents because of their consistent low sample activity.

An entry of O.OOE+Ol indicates that the Minimum Detectable Activity (MDA) concentration of the radionuclide was below the LLD value listed in Table 3.

SECTION 6 DOSE MEASUREMENTS AND ASSESSMENTS This section of the Annual Effluent Release Report provides the dose received by receptors around CPS fro_m gase_ous and liquid effluents. The dose to the receptor that would have received the highest dose in each sector (defined as the Critical Receptor for that sector) is listed within this report. This section also provides the d_ose to individuals who were inside the Site Boundary. This section also summarizes CPS's compliance with the requirements found within 49CFR190.

The 2016 maximum expected annual dose from Carbon-14 released from CPS has been calculated using the methodology included in the EPRI Technical Report 1021106 using the maximum gross thermal capacity maintained for 342.23 days of equivalent full power operation.

The assumptions used in determining dose values are as follows:

  • All receptors within a five (5) mile radius are included in the Annual Land Use Census. Thi.s Annual Census determines what dose pathways are present as well as the distance of each receptor from the site.
  • The annual average meteorological data for 2016 was used in conjunction with the Annual Land Use Census to determine the dose to each receptor within five (5) miles.
  • The doses for each receptor from 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 2016 including radionllclides with half-lives less than eight (8) days and when dose pathway factors were available.
  • The occupancy factor was taken into consideration by calculating the dose to individuals using areas inside the Site Boundary in non-residential areas. The occupancy factor is determined by dividing the number of hour[s] of occupancy per year (taken from the ODCM) and dividing that value by the total number of hour[s] per year.
  • Dose to individuals using areas inside the Site Boundary (that are not residences) was calculated using the Ground Plane and Inhalation pathways.

COMPLIANCE WITH 40CFR190 REQUIREMENTS Dosimeter of Legal Records [DLR] are stationed around CPS to measure the ambient gamma* radiation field. Monitoring stations are placed near the site boundary and approximately five (5) miles from the reactor, in locations representing the sixte.en (16) compass sectors. Other locations are chosen to measure the radiation field at places of special interest such as n~arby residences, meeting places and population centers. Control sites are located fUrther than ten (10) miles from the site, ih areas that should not be affected by plant operations. The* results from the TLDs are reported in the Annual Radiological Environmental Operating Report (AREOR). The results from this effort indicated no excess dose to offsite areas.

Additionally, NUREG-0543, METHODS FOR DEMONSTRATING LWR COMPLIANCE WITH THE EPA URANIUM FUEL CYCLE STANDARD (40 CFR PART 190) states in section IV, "As long as a nuclear plant site operates at a level below the Appendix I reporting requirements, no extra analysis is required to demonstrate compliance with 40 CFR Part 190." The organ and whole body doses reported in Table 8 are determined using 10 CFR 50 Appendix I methodology. The doses reported are well below the limits of Appendix I.

DOSE TO MEMBERS OF THE PUBLIC WITHIN THE SITE BOUNDARY CPS Offsite Dose Calculation Manual section 6.2 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 that are open to members of the public as identified by CPS ODCM Table 5-3 (see Figure 4):

The Department of Natural Resources Recreation Area at 1.287 kilometers (0.8 miles) in the ESE sector A road at 0.495 kilometers (0.3 miles) in the SE sector 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 Agricultural acreage at 1.372 kilometers (0.9 miles) in the SSW sector 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 sector At all of the above locations, the plume, inhalation and ground-plane exposure pathways are used for dose calculations. The 2016 Annual Land Use Census identified no other exposure pathways. All dose calculations were performed using the methodology contained in the CPS ODCM, with the exception of dose due to C-14, which was calculated using methodology included in the EPRI Technical Report 1021106.

SECTION 7 METEOROLO~ICAL DATA AND DISPERS.ION ESTIMAT~S

    • '.

on* 13 April 1972, the -meteorologi~al monitoring program commenced at the Clinton Power Station site. The meteorological system con'sists of a tower 199 f~et high with two (2) l~vels of instrume. ntation at th.e 10-meter and 60-meter elevations. A combined cup and vane sen~_or measures wind direction and wind speed[s] at the 10-meter and 60-meter levels. An aspirated dual temperature sensor senses the temperatur~s at these levels. 6ne-t1aJf of the c;lual sensors at each elevation ~re used for a~bient temperature while the other half are used to provide a differen.tial temperature between ttie 10~meter ahd 60-meter levels.

Meteorological monitoring instruments have been placed on the CUnton Power Station microwave tower a_t the 10-meter level to serve as a backup to the primary meteorological tower.

Clinton Power Station meteorological data is transmitted to the Main Control Room (MCR) via a dedicated communication link. Once the signals are received at the MCR, they are then converted to a 4 to 20 milliamp signal and fed individually t_o a microprocessor and~chart.

recorders. The microprocessor is part of the Clinton Power Station Radiation Monitoring*

System (RMS). Meteorological data is available via the microprocessors in the Main Control Room and the Technical Support Center (TSC).

Dispersion modeling for effluents for normal opf!ration .of Clinton Power Station is a straight-line, sector-averaged Gaussian plume model designe,d 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 distribution. For hourly input data, periods of calm are the previous hour's wind direction. Periods of calm are assigned a wind speed value. of half the specified instrument threshold value. Reference Table 18 for more detailed information on meteorology and dispersion data.

SECTION 8.

ODCM OPERATIONAL REMEDIAL REQUIREMENT REPORTS In accordance with CPS ODCM 3.1.1 Action G and 3.2.2 Act.ion G.1; INOPERABLE radioactive liquid and gaseous effiuent monitoring instrumentation channels remaining in an INOPERABLE condition for greater than thirty (30) days shall be reported in the Annual Radioactive Effluent Release Report.

During the course of 2016, there was one (1) instance where Channel 1 from OUIX-PR051-151-1 was INOPERABLE for greater than a thirty (30) day period, which carried over from the end of 2015 into 2016 since it could not be worked until C1R16. This issue was corrected and the Stand-by Gas Treatment System (SGTS) Flow Rate Measuring Device was returned to functional. That event is documented below.

December 9, 2015 -- Issue Report# 02597597 OUIX-PR051-151-1, Stand-by Gas Treatment System (SGTS) Flow Rate Measuring Device was declared INOPERABLE on November 9, 2015 at 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />.

During troubleshooting by Instrument Maintance Technicians under Work Order #1877501, it was determined that to repair this instrument, both trains of SGTS would have to be declared INOPERABLE. So this repair will be performed during C1R16, which is commencing May 16, 2016.

During periods when SGTS is placed into service and when coupled with this INOPERABLE channel, the station will comply with ODCM Table 3.2.2.1, ACTION E.2 by estimating SGTS flow rates when releases are occurring via this pathway once every four (4) hours (three (3) hours with our% Administrative Rule).

In summary, the extended INOPERABLE condition was the result of the potential of placing the Un if at risk by having to make both trains of SGTS INOPERABLE and having to enter an immediate Shutdown ACTION Statement.
