INTRODUCTION LaSalle County Station, a two-unit BWR station is located near Marseilles, Illinois in LaSalle County, 3.5 miles south of the Illinois River. The output of Unit one is 1183 MWe; the output of Unit 2 is 1187 MWe. Unit No. 1 loaded fuel in March 1982. Unit No. 2 loaded fuel in late December 1983. The station has been designed to keep releases to the environment at levels below those specified in the regulations.

Liquid effluents from LaSalle County Station are released to the Illinois River in controlled batches after radioassay of each batch. Gaseous effluents are released to the atmosphere after delay to permit decay of short-lived (noble) gases. Releases to the atmosphere are calculated on the basis of analyses of routine grab samples of noble gases 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 and reported to the Nuclear Regulatory Commission as required per Technical Specifications. Airborne concentrations of noble gases, I-131, and particulate radioactivity in offsite 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 LaSalle County Station to measure changes in radiation or radioactivity levels that may be attributable to station operations.

If significant changes attributable to LaSalle County Station are measured, these changes are correlated with effluent releases. External gamma radiation exposure from noble gases and internal dose from I-131 in milk are the most critical pathways at this site; however, an environmental monitoring program is conducted which includes these and many other pathways which are less significant in terms of radiation protection.

SUMMARY

Gaseous and liquid effluents for the period contributed to only a small fraction of the LaSalle County Station Technical Specification limits. Calculations of environmental concentrations based on effluent, Illinois River flow, and meteorological data for the period indicate that consumption by the public of radionuclides attributable to LaSalle County Station does not exceed regulatory limits. Radiation exposure from radionuclides released to the atmosphere represented the critical pathway for the period with a maximum individual total dose estimated to be 1.lE-01 mrem for the year, where a shielding and occupancy factor of 0.7 is assumed. The assessment of radiation doses is performed in accordance with the Offsite Dose Calculation Manual (ODCM). The results of analysis confirm that the station is operating in compliance with 10CFR50 Appendix I, 10CFR20 and 40CFR190.

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 1.33E+04 curies of fission -and activation gases were released with a maximum quarterly average release rate of 7.57E+02 liCi/sec.

A total of 3.16E-01 curies of I-131 were released during the year with a maximum quarterly average release rate of 2.05E-02 jiCi/sec.

A total of 2.8 E-02 curies of beta-gamma emitters was released as airborne particulate matter with a maximum quarterly average release rate of 1.92E-03 giCi/sec. A total of 4.58E-05 curies of alpha-emitting radionuclides was also released.

A total of 1.14E+02 curies of tritium was released with a maximum quarterly average release rate of 4.93E+00 iCi/sec.

1.2 Liquids Released to Illinois River There were zero batch liquid releases in 2002. Continuous release path activity was below applicable Lower Limits of Detection.

2.0 SOLID RADIOACTIVE WASTE Solid radioactive wastes were shipped by truck to the Envirocare Disposal Facility or to a waste processor. For further detail, refer to the LaSalle 2002 Radioactive Effluent Report.

The submittal date of this report was May 1, 2003;.

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 Gamma Dose Rates Unit I and Unit 2 gaseous releases at LaSalle County Station are reported as Unit 1 releases due to a single station vent stack (SVS) release point. Offsite Gamma air and whole body dose rates are shown in Table 3.1-1 and were calculated based on measured release rates, isotopic composition of the noble gases, and average meteorological data for the period.

Doses based on concurrent meteorological data are shown in Table 3.4-1.

Isodose contours based on concurrent meteorological data for gamma dose for the year are shown in Figure 3.1-1.

Based on measured effluents and meteorological data, the maximum total body dose to an adult would be 1.1 1E-01 mrem (Table 3

3. 1-1) for the year, with an occupancy or shielding factor of 0.7 included.

The maximum total body dose based on measured effluents and concurrent meteorological data would be 6.72E-02 mrem. (Table 3.4-1).

The maximum gamma air dose was 1.47E-01 mrad (Table 3.1-1) and 2.38E-01 mrad based on concurrent meteorological data (Table 3.4-1).

3.1.1.2 Beta Air and Skin Rates The range of beta particles in air is relatively small (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 thickness of 7.0 2

mg/cm and an occupancy factor of 1.0 is used. The skin dose from beta and gamma radiation for the year was 1.18E-01 mrem (Table 3.1-1) and 7.97E-02 mrem (Table 3.4-1) based on concurrent meteorological data.

The maximum offsite beta air dose for the year was 6.74E-03 mrad (Table 3.1-1) and 2.35E-02 mrad (Table 3.4-1) based on concurrent meteorological data. 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. The radioiodine, -131, released during routine operation of the plant, may be made available to man resulting in a dose to the thyroid. The principal pathway of interest for this radionuclide is ingestion of radioiodine in milk.

3.1.2.1 Iodine 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 vhich accounts for the phenomenon of elemental iodine deposition on the ground.

The maximum offsite concentration is estimated to be 1.70E+01 pCilm for the year (Table 3.4-1).

3.1.2.2 Dose to Thyroid The hypothetical thyroid dose to a maximum exposed individual living near the station via ingestion of milk was calculated. The radionuclide considered was I-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 due to I-131 was 4.10E-01 mrem (child) for the year (Table 3.1-1).

4

3.1.3 Concentrations of Particulates in Air Concentration contours of radioactive airborne particulates are shown in Figure 3.1-4. The maximum offsite average level is estimated to be 1.46E-04 pCi/m.

(Table 3.4-1) 3.2 Liquid Effluent Pathwavs The three principal pathways through the aquatic environment for potential doses to man from liquid waste are ingestion of potable water, eating aquatic foods, and exposure Nvhile on the shoreline. Not all of these pathways are applicable at a given time 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 tracts, thyroid, bone, skin; specific parameters for use in the equations are given in the Offsite Dose Calculation Manual. The maximum whole body dose was O.OOE+00 and organ dose was O.OOE+00 for the year (Table 3.2-1).

3.3 Assessment of Dose to Member of Public During the period January to December, 2002, LaSalle County Station did not exceed these limits as shown in Table 3.1-1 and Table 3.2-1 (based on yearly average meteorological data), and as shown in Figure 3.1-1 (based on concurrent meteorological data), and as shown in Table 3.3-1:

The Radiological Effluent Technical Standards 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 iodine-131, iodine-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 OCFR20 limit on Total Effective Dose Equivalent to individual members of the public (100 mrem).

4.0 SITE METEOROLOGY 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 375' level and wind speed class by atmospheric stability class determined for the temperature difference between the 375' and 33' levels.

Data recovery for these measurements was 99.5% during 2002 (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 the current Technical Standards. Tables 5.0-2 lists the program's sampling locations, collection frequencies and analyses for all samples collected. Tables 5.0-3 to 5.0-6 summarize data for the year.

A detailed listing of all data is given in Appendix Im.

Specific findings for various environmental media are discussed below.

5.1 Gamma Radiation External radiation dose from onsite sources and noble gases released to the atmosphere was measured using CaF2 thermoluminescent dosimeters (TLDs).

Each location normally consists of 2 TLD sets. The quarterly average external radiation dose for the year was 23.8 miR at the indicator locations and 21.3 mR at the control locations. TLD results are listed in Table 4.0 of Appendix I and locations are shown in Figures 5.0-1 and 5.0-2.

Quarterly external radiation dose at indicator air sampling locations averaged 23.3 mR and is similar to levels measured in 1986 (17.1 mR), 1987 (17.8 mR), 1988 (16.5 mR),

1989 (17.6 mR), 1990 (17.8 mR), 1991 (17.7 mR), 1992 (15.5 mR), 1993 (14.5 mR),

1994 (15.4 mR), 1995 (15.3 mR), 1996 (15.9 mR) and 1997 (16.1 mR), 1998 (17.0 mR), 1999 (17.0 mR), 2000 (17.9 miR) and 2001 (20.1 mR). These differences are not statistically significant.

5.2 Airborne 1-131 and Particulate Radioactivity Locations of the samplers are shown in Figure 5.0-3. Airborne I-131 remained below the LLD of 0.07 pCi/m throughout the year.

Gross beta concentrations ranged from 0.011 to 0.053 pCi/m and averaged 0.027 3

3 pCi/m3 and were similar to levels measured in 1985 (0.025 pCi/m ), 1986 (0.027 pCi/m, except for the period from May 16 through June 6 when it was influenced by the nuclear reactor accident at Chemobyl), 1987 (0.027 pCi/m ), 1988 (0.031 pCi/m),

Gamma isotopic results were below the LLD level of 0.01 pCi/m3 in all quarterly composites.

No activity attributable to station operation was detected in any sample.

5.3 Aquatic Radioactivity Well water was collected quarterly from one onsite well and one offsite well and analyzed for tritium and gamma-emitting nuclides. All results were below the limits of detection, indicating that there was no measurable amount of radioactivity due to the Station's releases.

Weekly surface water samples from the Illinois River at Seneca and Illinois River Downstream were composited monthly and analyzed for gamma and beta-emitting nuclides.

Weekly samples from the same locations were composited quarterly and analyzed for tritium.

None of the composited samples indicated the presence of gamma-emitting nuclides above their respective LLD levels.

Gross beta activity averaged 5.3 pCilL in the Illinois River at Seneca samples, with a range of 3.8-8.4 pCifL. The Illinois River, Downstream sample averaged 5.5 pCi/L, with a range of 4.2-7.4 pCi/L.

Tritium activity in the quarterly upstream samples, Illinois River at Seneca, averaged 327 pCi/L with a maximum fourth quarter concentration of 702 pCi/L. In the Illinois River DoNvnstream samples, tritium activity averaged 417 pCi/L with a maximum fourth quarter concentration of 827 pCi/L. These values are well below the reporting level of 30,000 pCi/L.

Sediment samples were collected twice a year from two indicator locations (Illinois River, Downstream) and analyzed for gamma-emitters.

Cs-134 and Cs-137 concentrations were below the detection limits of 0.15 pCi/g dry weight and 0.18 pCi/g dry weight, respectively, in all samples.

Levels of gamma radioactivity in fish were measured and found in all samples to be below the lower limit of detection for the program.

5.4 Milk Milk samples were collected monthly from November through April and biweekly from May through October and analyzed for Iodine-131 and gamma-emitting nuclides.

1-131 remained below the detection limits of 0.5 pCi/L (May - October) and 5.0 pCi/L (November - April). Cs-134, Cs-137 and Ba/La-140 were below the LLD levels of 15, 18 and 15 pCi/L, respectively.

7

5.5 Terrestrial Radioactivity Vegetables were collected in the third quarter and analyzed for iodine-131 and gamma-emitting nuclides. All nuclides were below the limits of detection, indicating there was no measurable amount of radioactivity attributable to the Station's releases.

5.6 Sample Collections All samples were collected as scheduled except those listed in the Listing of Missed Samples, Section 2 of Appendix III.

5.7 Program Modifications There were no changes to the program in 2002.

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 VI of the Annual Radiological Environmental Operating Report for 1993. The submittal date for this report was April 26, 1994.

7.0 MILCH ANIMALS AND NEAREST LIVESTOCK CENSUS A census of milch animals vas conducted within a 6.2-mile radius of the Station. The survey was conducted by "door-to-door" canvas by A. Lewis on August 26, 2002. The nearest livestock census was conducted by A. Lewis on August 26, 2002. The results of each census are presented on pages 31 and 32 of Appendix III.

1.0 INTRODUCTION

The following constitutes the 2002 Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at the LaSalle County Station, Marseilles, Illinois. Results of completed analyses are presented in the attached tables. Missing entries indicate analyses that are not completed and the results will appear in subsequent reports.

Missing tables indicate sample media scheduled for collection at a future date. Tables will appear in subsequent reports.

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/Nb-95, I-131, BaALa-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 Sample Type Location Collection Comments Code Date None for 2002.

APPENDIX IV INTERLABORATORY COMPARISON PROGRAM RESULTS Iv-I

Appendix IV lnterlaboratorv Comparison Program 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 'spiked" 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 duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.

The results in Table 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.

Attachment A lists acceptance criteria for spiked' samples.

Out-of-limit results are explained directly below the result.
