INTRODUCTION Braidwood Station, a two-unit Pressurized Water Reactor station, is located in Will County, Illinois, 15 miles south-southwest of Joliet, Illinois. Each reactor is designed to have a capacity of 3586.6 thermal megawatts. Unit 1 went critical on May 29, 1987, and Unit 2 went critical on March 8, 1988. The station has been designed to keep releases to the environment at levels below those specified in the regulations.

Liquid effluents from Braidwood Station are released to the Kankakee River in controlled batches after radioassay of each batch. Gaseous effluents are released to the atmosphere and are calculated on the basis of analyses of grab samples of noble gases and tritium, as well as continuously collected composite samples of iodine and particulate radioactivity sampled during the course of the year. The results of effluent analyses are summarized on a monthly basis.

Airborne concentrations of noble gases, Iodine-1 31 (1-131), and particulate radioactivity in offaite areas are calculated using effluent and meteorological data.

Environmental monitoring is conducted by sampling at indicator and control (background) locations in the vicinity of the Braidwood Station to measure changes in radiation or radioactivity levels that may be attributable to station operations. If significant changes attributable to Braidwood Station are measured, these changes are correlated with effluent releases. External gamma radiation exposure from noble gases and internal dose from 1-131 in milk are the most critical pathways at this site; however, an environmental monitoring program is conducted which includes these and other pathways.

SUMMARY

Calculations based on gaseous and liquid effluents, Kankakee River flow and meteorological data indicate that public dose due to radioactive material attributable to Braidwood Station in the year 2003 does not exceed regulatory or Offsite Dose Calculation Manual (ODCM) limits.

The Total Effective Dose Equivalent (TEDE) due to licensed activities at Braidwood Station calculated for the maximally-exposed public individual in the year 2003 is 1.98E+00 mrem. The annual limit on TEDE is 100 mrem.

The assessment of radiation doses to the public is performed in accordance with the ODCM. The results of these analyses confirm that the Station is operating in compliance with 10 CFR 50, Appendix I, "Domestic Licensing of Production and Utilization Facilities," 10 CFR 20, "Standards for Protection Against Radiation," and 40 CFR 190, "Environmental Radiation Protection Standards for Nuclear Power Operations."

1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere Measured concentrations of noble gases, radioiodine and particulate radioactivity released to the atmosphere during the year are listed in Table 1.1-1.

A total of 8.25E+01 curies of fission and activation gases were released with a maximum quarterly average release rate of 2.07E+02 #iCi/sec for Unit I and 2.04E+02 pCi/sec for Unit 2.

A total of 2.14E-03 curies of 1-131 were released with a maximum quarterly release rate of 9.67E-05 pCi/sec for Unit 1 and 3.93E-05 PCi/sec for Unit 2.

A total of 1.87E-05 curies of beta-gamma emitters were released as airborne particulate matter with a maximum quarterly average release rate of 2.1 1E-06 pCi/sec for Unit 1; Unit 2 release rate was less than Lower Limit of Detection (LLD). Alpha-emitting radionuclides were less than the LLD for the year.

A total of 3.31E+01 curies of tritium was released with a maximum quarterly average release rate of 2.06E+00 pCi/sec for Unit 1 and 1.31E+00 tCi/sec for Unit 2.

1.2 Liquids Released to Kankakee River A total of 1.38E+07 liters of radioactive liquid waste (prior to dilution) containing

1. lIE-01 curies (excluding tritium, noble gases, and alpha) was discharged from the station. These wastes were released at a maximum quarterly average concentration of 7.83E-09 pCi/mI. Alpha-emitting radionuclides were less than the LID for the year. A total of 2.64+03 curies of tritium was released from the station. Monthly release activities and principal radionuclides in liquid effluents are given in Table 1.2-1.

2.0 SOLID RADIOACTIVE WASTE Solid radioactive wastes were shipped by truck to the Envirocare of Utah disposal facility, the Barnwell, South Carolina disposal facility, and various waste processors.

For details, refer to the Braidwood Station 2003 Radioactive Effluent Release Report.

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways Table 3.1-1 summarizes the doses resulting from releases of airborne radioactivity via the different exposure pathways.

3.1.1 Noble Gases

3. 1.1.1 Gamnma D2ose Isodose contours based on concurrent meteorological data for gamma dose for the year are shown in Figure 3.1-1. Offsite gamma air and total body doses are shown in Table 3.1-1 and were calculated based on measured effluents and average meteorological data. Based on measured effluents and average meteorological data, the maximum total body dose to an individual would be 1.68E-02 mrem for the year (Table 3.1-1),

using an occupancy or shielding factor of 0.7. The maximum total body dose based on measured effluents and concurrent meteorological data was 5.64E-04 mrem (Table 3.4-1). The maximum gamma air dose was 1.57E-03 mrad (Table 3.1-1) based on measured effluents and average meteorological data and 9.74E-04 mrad based on concurrent meteorological data (Table 3.4-1).

3.1.1.2 Beta Air and Skin Dose The range of beta particles in air is relatively small (i.e., on the order of a few meters or less). Consequently, plumes of gaseous effluents may be considered "infinite" for the purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive skin tissues is difficult to calculate due to the effect of the beta particle energies, thickness of inert skin and clothing covering sensitive tissues.

For purposes of this report the skin is taken to have a density of 7.0 mg/cm and an occupancy factor of 1.0 is used. The skin dose from beta and gamma radiation for the year was 2.40E-03 mrem based on concurrent meteorological data (Table 3.4-1). The maximum offsite beta air dose for the year was 6.58E-03 mrad (Table 3.1-1) based on measured effluents and average meteorological data and 5.83E-03 mrad based on concurrent meteorological data (Table 3.4-1). The air concentrations of radioactive noble gases at the offsite receptor locations are given in Figure 3.1-2.

3.1.2 Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine and the radionuclide I-13 1. Minimal levels of radioiodine released during routine operation of the station may be made available to man, thus resulting in a dose to the thyroid. The pathway of interest for this radionuclide is ingestion of radioiodine in milk Calculations are performed annually but the levels released from the station in previous years indicated that contributions to doses from inhalation of 1-131 and Iodine-133 (1-133) and ingestion of 1-133 in milk are negligible.

3.1.2.1 Iodine-131 Concentrations in Air The calculated concentration contours for iodine in air are shown in Figure 3.1-3. Included in these calculations is an iodine cloud depletion factor which accounts for the phenomenon of elemental iodine deposition on the ground. The maximum annual offsite concentration is estimated to be 2.78E-04 pCi/m for the year (Table 3.4-1).

3.1.2.2 Dose to Thyroid The hypothetical thyroid dose to the maximum exposed individual living near the station via ingestion of milk was calculated. The radionuclide considered was 1-131 and the source of milk was taken to be the nearest dairy farm with the cows pastured from May through October. The maximum thyroid dose did not exceed 3.56E+00 mrem during the year (Table 3.1-1 [infant]).

3.1.3 Concentrations of Particulates in Air Concentration contours of radioactive airborne particulates are shown in Figure 3.1-4. The maximum annual offsite concentration is estimated to be 4.24E+00 pCi/m (Table 3.4-1).

3.2 Liquid Effluent Pathways The three principal pathways through the aquatic environment for potential doses to man from liquid waste are the ingestion of potable water, eating of aquatic foods, and exposure while on the shoreline. Not all of these pathways are significant or applicable at a given time or station but a reasonable approximation of the dose can be made by adjusting the dose formula for season of the year or type and degree of use of the aquatic environment. NRC developed equations* were used to calculate the doses to the whole body, lower gastro-intestinal (GI) tracts, thyroid, bone, skin. Specific parameters for use in the equations are given in the Exelon Offsite Dose Calculation Manual. The maximum whole body dose for the year was 1.27E-01 mrem and no organ dose exceeded 1.93E-01 mrem (Table 3.2-1 [adult]).

3.3 Assessment of Dose to Member of Public During the period January to December, 2003, Braidwood Station did not exceed the following limits as shown in Table 3.1-1 and Table 3.2-1 (based on annual average meteorological data), Figure 3.1-1 (based on concurrent meteorological data), and Table 3.3-1:

• Nuclear Regulatory Commission, Regulatory Guide 1.109, Revision 1, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I" 5

• The Radiological Effluent Technical Specifications (RETS) limits on dose or dose commitment to an individual due to radioactive materials in liquid effluents from each reactor unit (1.5 mrem to the whole body or 5 mrem to any organ during any calendar quarter; 3 mrem to the whole body or 10 mrem to any organ during any calendar year).

• The RETS limits on air dose in noble gases released in gaseous effluents to a member of the public from each reactor unit (5 mrad for gamma radiation or 10 mrad for beta radiation during any calendar quarter; 10 mrads for gamma radiation or 20 mrad for beta radiation during any calendar year).

• The RETS limits on dose to a member of the public due to 1-131, 1-133, tritium, and radionuclides in particulate form with half-lives greater than eight days in gaseous effluents released from each reactor unit (7.5 mrem to any organ during any calendar quarter; 15 mrem to any organ during any calendar year).

• The 10 CFR 20 limit on Total Effective Dose Equivalent to individual members of the public (100 mrem).

4.0 SITE METEOROLOGY0 A summary of the site meteorological measurements taken during each calendar quarter of the year is given in Appendix II. The data are presented as cumulative joint frequency distributions of the wind direction for the 203 foot elevation and wind speed class by atmospheric stability class determined from the temperature difference between 199 and 30 foot elevations. Data recovery for these measurements was 99.8% during 2003 (Table 3.4-1).

5.0 ENVIRONMENTAL MONITORING Table 5.0-1 provides an outline of the Radiological Environmental Monitoring Program (REMP) as required in current Technical Standards. Table 5.0-2 lists the sampling locations, sampling collection frequencies and analyses performed. Sampling locations are shown in Figures 5.0-1 to 5.0-4. Concentrations of radioactivity in various media are summarized in Tables 5.0-3 through 5.0-6. Tables listing all data are presented in Appendix Ill.

Specific findings for various environmental media are discussed below.

5.1 Gamma Radiation External radiation dose was measured using Calcium Flouride (CaF2) thermoluminescent dosimeters (TLDs). Each location consists of two TLD sets. The quarterly average external radiation dose for the year was 21.6 mrem at the indicator locations and 21.9 mrem at the control locations. TLD results are listed in Section 6.0 of Appendix m and locations are shown in Figures 5.0-1 and 5.0-2.

6

Quarterly external radiation dose at indicator air sampling locations averaged 20.2 mrem. Previous measurements are as follows: 1985 (12.0 mrem), 1986 (12.6 mrem),

1987 (14.4 mrem), 1988 (13.6 mrem), 1989 (13.5 mrem), 1990 (14.6 mrem),

1991 (14.2 mrem), 1992 (13.9 mrem), 1993 (14.1 mrem), 1994 (13.7 mrem),

1995 (12.3 mrem), 1996 (13.1 mrem), 1997 (13.6 mrem), 1998 (14.5 mrem),

1999 (13.9 mrem), 2000 (14.7 mrem), 2001 (19.1 mrem) and 2002 (20.2 mrem). A different style of TLD was used starting in 2001. A different algorithm is used to read these TLDs, which accounts for the higher indicated dose.

5.2 Airborne I-131 and Particulate Radioactivity Airborne 1-131 concentration remained below the LLD of 0.07 pCi/M3 throughout the year in all samples. Locations are shown in Figure 5.0-2.

Gross beta concentrations ranged from 0.014 to 0.048 pCi/mn 3 and averaged 0.026 pCi/m3 and was similar to the average concentration in 1985 (0.028 pCi/m),

1986 (0.034 pCi/mr3 , except for the period from May 16 through June 6 when it was influenced by the nuclear reactor accident at Chernobyl), 1987 (0.027 pCi/m3),

1988 (0.031 pCi/mr), 1989 (0.028 pCi/m3), 1990 (0.024 pCi/m3 ), 1991 (0.022 pCi/m ),

393 3 1992 (0.022 pCi/mr), 1993 (0.022 pCi/mi), 1994 (0.021 pCi/m3), 1995 (.0.023 pCi/m3),

1996 (0.022 pCi/rm3 ), 1997 (0.023 pCi/rn) 1998 (0.025 pCi/n) 1999 (0.027 pCi/rn3 ),

2000 (0.028 pCi/n 3 ), 2001 (0.027 pCi/m3) and 2002 (0.028 pCi/m3 ).

All gamma-emitting nuclide activity was below respective LLD levels. No activity attributable to station operation was detected in any sample.

5.3 Terrestrial Radioactivity Vegetables were collected in August and analyzed for I-131 and gamma-emitting nuclides. 1-131 and gamma-emitting nuclides were below the LLD indicating that there was no measurable amount of radioactivity attributable to the station releases.

5.4 Aquatic Radioactivity Well water was collected quarterly from one nearsite well (BD-13) and four farsite wells (BD-34, BD-35, BD-36, BD-37) and was analyzed for tritium and gamma-emitting nuclides. Tritium levels at BD-13, BD-34, BD-35 and BD-37 remained below the LLD level of 200 pCilL. Tritium levels at BD-36 averaged 426 pCi/L with a fourth quarter high of 484 pCi/L. All gamma-emitters were below the LLD. These results are similar to those obtained since 1991 when tritium well water sampling was initiated.

Weekly surface water samples from BD-10 (Kankakee River, Downstream) and BD-25 (Kankakee River, Upstream) were composited monthly and analyzed for gamma-emitting nuclides and gross beta activity. Quarterly composites were analyzed for tritium. Public water samples from BD-22 (Wilmington) were also composited monthly and analyzed for gamma-emitting nuclides, gross beta and tritium. Weekly composite 7

samples from BD-22 are analyzed for tritium to provide information and trending.

These samples and analyses are not required by the ODCM or Radiological Environmental Monitoring Program (REMP). During February, 2003, a weekly sample indicated a higher than normal tritium level at 22,971+/-415 pCi/liter. This sample was re-analyzed and the result confirmed. The high result was attributed to composite sampler solenoid problems. This issue was documented in the Braidwood Station corrective actions program.

Cesium-134 (Cs-134) and Cesium-137 (Cs-137) concentrations were below the LLD level of 15 pCi/L and 18 pCi/L, respectively, in all samples.

Gross beta concentrations at BD-10 averaged 3.5 pCi/L with a range of 2.0 pCi/L to 5.5 pCi/L; concentrations at BD-25 averaged 5.2 pCi/L with a range of 3.0 pCi/L to 7.3 pCi/L. Gross beta concentrations at BD-22 averaged 3.3 pCi/L with a range of 2.1 pCi/L to 4.7 pCifL-Tritium concentrations at BD-10 and BD-25 remained below the LLD level of 200 pCi/L in all samples. Tritium concentrations in public water samples (BD-22) averaged 1,379 pCi/L with a range of 67 pCi/L to 7,537 pCilL. These values are less than the reportable level of 20,000 pCi/L for drinking water, and are attributable to plant operation. These results were consistent with plant effluent releases and river flow dilution.

Sediment samples were collected twice a year, in May and October, from two indicator locations (BD-10 and BD-41) and analyzed for gamma-emitters. Cs-134 and Cs-137 concentrations were at or below the LLD (0.15 pCi/g and 0.18 pCi/g dry weight, respectively) in all samples. These values are similar to those obtained in 1986 through 2002.

Levels of gamma radioactivity in fish were measured and all samples were below the LLD for the year.

Water, fish and sediment locations are shown in Figure 5.0-3.

5.5 Milk Milk samples were collected monthly from November 2002 through April 2003 and biweekly from May through October and analyzed for I-131 and gamma-emitting nuclides. Milk locations are shown in Figure 5.0-3.

I-131 concentration was below the LID level of 1.0 pCi/L in all samples.

Cs-134, Cs-137 and Barium/Lanthinum-140 (Ba/La-140) were below the LLD level of 15 pCi/L, 18 pCi/b and 15 pCi/b, respectively. These results are identical to those obtained in 1986 through 2002.

8

5.6 Sample Collections All samples were collected as scheduled except those listed in the Listing of Missed Samples, Section 2.0 of Appendix Iml.

5.7 Program Modifications There were no changes to the program in 2003.

6.0 ANALYTICAL PROCEDURES Procedures used during the period covered in this report remained unchanged. A summary of the procedures used for analyzing radioactivity in environmental samples is given in Appendix V of the report for the period January - December 1993.

7.0 MILCH ANIMALS AND NEAREST LIVESTOCK CENSUS A census of milch animals and nearest cattle was conducted within a 6.2-mile radius of the Station. The survey was conducted by "door-to-door" canvas and by information from Illinois Agricultural Agents. The census was conducted by Environmental, Inc. Midwest Laboratory on August 26, 2003.

Results of the milch animal and nearest cattle census are presented in Section 5.0 of Appendix III on pages 39 and 40.

8.0 NEAREST RESIDENCE CENSUS A census of the nearest residences within a 6.2-mile radius was conducted by Environmental, Inc. Midwest Laboratory on August 26, 2003.

Results of the nearest residence census are presented in Section 5.0 of Appendix In on page 41.

9.0 INTERLABORATORY COMPARISON PROGRAM RESULTS Environmental Incorporated's Interlaboratory Comparison Program Results are presented in Appendix IV.

10.0 ERRATA DATA There is no errata data for 2003.

1.0 INTRODUCTION

The following constitutes the 2003 Progress Report for the Radiological Environmental Monitoring Program conducted at the Braidwood Station, Braceville, Illinois. Results of completed analyses are presented in the attached tables.

Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the environmental media sampled.

For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 keV. Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Ba-140, La-140, Cs-134 and Cs-137. Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but not listed here. The data is reported in the format of x*2s;2TPU, where "x" is the significant result, "s" is the one standard deviation counting uncertainty, and TPU is the total propagated uncertainty at the one sigma confidence level.

Locations denoted by a "(C)" after site code refer to control locations.

All concentrations, except gross beta, are decay corrected to the time of collection.

TLD data is provided by Exelon Generation Company.

Deviations from Scheduled Sampling and Corrective Actions Taken All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples.

Unusual Environmental Measurements None for 2003.

AmDendix A Interlaboratory Comparison Pro-ram 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 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.

Results In Table IV-1 were obtained through participation In the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.

The results in Table IV-2 were obtained for Thermoluminescent Dosimeters (TLDs), via Intemational Intercomparison of Environmental Dosimeters under the sponsorships listed In Table A-2. Results of Internal laboratory testing Is also listed.

Table IV-3 lists results of the analyses on In-house uspiked' samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.

Table IV-4 lists results of the analyses on In-house *blank" samples for the past twelve months. Data for previous years available upon request. request.

Table IV-5 list results of the In-house Oduplicate' 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 IV-6 were obtained through participation In the Mixed Analyte Performance Evaluation Program.

The results In Table IV-7 were obtained through participation In the Environmental Measurement Laboratory Quality Assessment Program.
