INTRODUCTION The Dresden Station is located approximately twelve miles southwest of Joliet, Illinois at the confluence of the Des Plaines and Kankakee Rivers where they form the Illinois River. This station uses two boiling water reactors (G.E. design) to generate electricity. Unit 1, which began operating in 1960 and had a rated power output of 200 megawatts electrical (MWe), was shut down permanently on August 31, 1984 and is currently being decommissioned. Unit 2 net rated power output was increased to 912 MWe in 2001; Unit 3 net rated power output was increased to 912 MWe in 2002. Liquid radwaste from Unit 1 is transferred to Units 2 and 3 for collective processing and discharge.

Liquid effluents from Dresden 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 weekly grab samples of noble gases as well as continuously collected composite samples of iodine and particulate activity 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 isotopic composition of control effluent and meteorological data.

Environmental monitoring is conducted by sampling at indicator and -control (background) locations in the vicinity of the Dresden Station to measure changes in radiation or radioactivity levels that may be attributable to station operation. If significant changes attributable to Dresden are measured, these changes are correlated with effluent releases. External gamma radiation exposure from turbine shine and released noble gases, and internal dose from I-131 in milk are the critical pathways at this site; however, a comprehensive environmental monitoring program is conducted which includes many other pathways which are less significant in terms of radiation protection.

SUMMARY

Calculations based on gaseous and liquid effluents, Illinois River flow, meteorological data and hydrogen addition activities indicate that public dose due to radioactive material attributable to Dresden Station during the period does not exceed regulatory or Offsite Dose Calculation Manual (ODCM) limits.

The Total Effective Dose Equivalent (TEDE) for the period due to licensed activities at Dresden Station calculated for the maximally-exposed individual is 7.03 mrem. The annual limit on TEDE is 100 mrem. This value is largely dominated by the direct radiation constituent from the Unit 2 and Unit 3 turbines (7.02 mrem). The balance of the calculated maximum dose (0.01 mrem) is due to exposure from radionuclides released from the Station in liquid and gaseous effluents.

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 10CFR50 Appendix I, 10CFR20 and 40CFR1 90.

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

1. A total of 1.06E+02 curies of noble gases with a maximum quarterly average release rate of 4.61 E+00 [tCi/sec were released from Dresden Units 1, 2 and 3.

A total of 3.09E-03 curies of 1-131 were released during the year with a maximum quarterly average release rate of 1.12E-04 pCi/sec.

A total of 5.55E-03 curies of beta-gamma emitters were released as airborne particulate matter with a maximum quarterly average release rate of 2.01E-04 giCi/sec. Alpha emitting radionuclides were below LLD for the period.

Also, 2.34E+01 curies of tritium were released with a maximum quarterly average release rate of 8.99E-01 pCi/sec.

1.2 Liquids Released to Illinois River Measured concentrations and isotopic composition of radioactivity released in liquid effluents during the year are listed in Table 1.2-1.

A total of 4.39E+06 liters of radioactive liquid wastes containing 1.06E-02 curies of fission and activation products (excluding tritium, noble gases and gross alpha) were discharged from the station. These wastes were released at a maximum quarterly average diluted concentration of 1.65E-08 jiCi/ml from all units. During the same period, 1.95E+01 curies of tritium were released with a maximum quarterly average diluted concentration of 3.03E-05 glCi/ml. Alpha-emitting radionuclides were belowv LLD.

2.0 SOLID RADIOACTIVE WASTE Solid radioactive wastes were shipped by truck to the Barnwell disposal facility, the Envirocare disposal facility or to waste processors.

For more detail, refer to the Dresden Station 2004 Annual Radiological Effluent Release Report.

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways 3.1.1 Noble Gases To demonstrate compliance with the applicable regulations regarding public radiation dose due to gaseous effluents from Dresden Station, two methods are reported in the following sections. Both methods employ measured isotopic composition and release rates from the station.

Assumed "average meteorological data" are used in ODCM-required calculations performed at least every 31 days. These data use a ten-year average 3

(1/1/1978-12/31/1987) for Dresden Station. Actual "concurrent meteorological data" is used to recalculate the quarterly release information using actual meteorological data for the period.

3.1.1.1 Gamma Air Dose Rates Offsite gamma air and total body doses 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.

Based on measured effluents and average meteorological data, the maximum total body dose (from all units) to an individual is calculated to be 1.59E-03 mrem (Table 3.1-1) for the year, with an occupancy or shielding factor of 0.7 included. The maximum total body dose from all units based on measured effluents and concurrent meteorological data would be 3.02E-03 mrem (Table 3.4-1). The maximum gamma air dose based on measured effluents and average meteorological data was 2.1 1E-03 mrad (Table 3.1-1) and 3.84E-03 mrad based on concurrent meteorological data (Table 3.4-1).

3.1.1.2 Beta Air and Skin Dose 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 assumed to have a thickness of 0.07 mm and an occupancy factor of 1.0 is used. The skin dose from beta and gamma radiation based on measured effluents and average meteorological data for the year was 1.75E-03 mrem (Table 3.1-1) and 3.72E-03 mrem based on concurrent meteorological data (Table 3.4-1).

The maximum offsite beta air dose based on measured effluents and average meteorological data for the year was 1.48E-04 mrad (Table 3.1-

1) and 4.44E-04 mrad based on concurrent meteorological data (Table 3.4-1).

3.1.2 Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. The radioiodine, I-131, released during routine operation of the station, 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. Calculations made in previous years indicate that contributions to doses from inhalation of I-131 and 1-133 and from ingestion of 1-133 in milk are negligible.

4

3.1.2.1 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 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 is calculated to be 2.39E-02 mrem during the year (Table 3.1-1 [child]).

3.2 Liquid Effluent Pathways The three principal pathways for potential dose to man from liquid waste effluents are ingestion of potable water, ingesting aquatic foods, and exposure while on the shoreline. Not all of these pathways are 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 GI tract, thyroid, bone and skin; specific parameters for use in the equations are given in the Dresden Station Offsite Dose Calculation Manual. The maximum total body dose and organ dose for the year was 3.18E-04 mrem (child) and 3.70E-04 mrem (child/adult), respectively (Table 3.2-1).

3.3 Assessment of Dose to Member of Public During the period January to December, 2004, Dresden Station did not exceed the following limits as shown in Table 3.1-1 and Table 3.2-1 (based on average meteorological data) and as shown in Table 3.4-1 (based on concurrent meteorological data):

The RETS limits on dose or dose commitment to a member of the public due to radioactive materials in liquid effluents from each reactor unit (1.5 mrem to the total body or 5 mrem to any organ during any calendar quarter; 3 mrem to the total 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 mrad 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 8 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 10CFR20 limit on Total Effective Dose Equivalent to individual members of the public (100 mrem) from the site.

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 35' and 300' levels and wind speed class by atmospheric stability class determined from the temperature difference between the 150' and 35' and between the 300' and 35' levels, respectively.

Data recovery for all measurements on the tower was 99.2% during 2004 (Table 3.4-1).

5.0 ENVIRONMENTAL MONITORING Table 5.0-1 and Table 5.0-2 provide an outline of the Radiological Environmental Monitoring Program (REMP) as required in the ODCM. Tables 5.0-3 to 5.0-6 summarize data for the year by quarter. A detailed listing of all data is given in Appendix III.

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 consists of 2 TLD sets. Quarterly average external radiation dose for the year was 24.5 iz 3.2 mR at indicator locations and 22.4 + 3.1 mR at control locations. TLD results are listed in Section 6.0 in Appendix III and locations are shown in Figures 5.0-1 and 5.0-2.

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

Gross beta concentrations ranged from 0.2E-02 to l.1E-02 pCi/rn and averaged 3

2.4E-02 pCi/m, and were similar to those measured in previous years (except for the period from May 17 through June 7, 1986 when it was influenced by the nuclear reactor accident at Chernobyl).

The mean beta measurement value was below the control mean value for every quarter. Quarterly gamma isotopic results were below the LLD level of 0.01 pCi/m.

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

5.3 Terrestrial Activity Vegetables were collected in the third quarter and analyzed for I-131 and gamma-emitting nuclides. All nuclides were below the limits of detection, indicating that there was no measurable amount of radioactivity attributable to the station releases.

6

5.4 Aquatic Radioactivity Surface water samples were collected weekly from three locations, shown in Figure 5.0-2, and composited monthly for gross beta and gamma-emitters.

Quarterly composites were analyzed for tritium. Cs-134, Cs-137, and 1-131 levels were below the detection limit of 15, 18 and 15 pCi/L, respectively. All other gamma emitters were below their respective LLDs in all samples collected during the year.

Gross beta at D-51 (Dresden Lock & Dam) averaged 5.1 pCi/L with a range of 3.4 to 7.5 pCi/L; D-52 (DesPlaines River) gross beta averaged 6.4 pCi/L with a range of 3.8 to 9.1 pCi/L; D-54 (Kankakee River) gross beta averaged 3.3 pCi/L with a range of 2.2-4.8 pCi/L.

Tritium concentration was below the LD of 200 pCi/L in all samples collected from D-52 (DesPlaines River and D-54 (Kankakee River). D-51 (Dresden Lock & Dam) averaged 518 pCi/L with a range of 67 to 1,035 pCi/L.

Well water samples were collected quarterly and analyzed for tritium and gamma-emitting nuclides. Gamma-emitters were below LLD for all samples during the year; tritium activity at D-35 (Dresden Lock & Dam) was also below LLD. Tritium activity at D-23 (Thorsen Well) averaged 843 pCi/L with a second quarter high of 940 pCi/L.

Levels of gamma radioactivity in fish samples were measured and found in all cases to be below the lower limits of detection for the program. The results were similar to those obtained in 1983 through 2003.

Sediment samples were collected twice and analyzed by gamma spectroscopy. The levels of Cs-134 and Cs-137 were below the LLD levels of 0.15 and 0.18 pCi/g dry weight, respectively.

Other gamma emitters were below their respective LLDs for the program.

Fish, sediment and water locations are shown in Figure 5.0-2.

5.5 Milk Milk sample locations are shown in Figure 5.0-1.

Milk samples were collected biweekly during the grazing season (May through October) and monthly during the balance of the year from the Vince Biros Farm (D-25). I-131 was determined for each sample by chemical separation of 1-131 and beta counting.

1-131 remained below the ODCM-required detection limits of 1.0 pCi/L. The results were similar to those obtained during the 1983 - 2003 period except for samples collected during the second and third quarters of 1986. I-131 detected in milk samples during this period is attributable to the nuclear accident at Chemobyl.

5.6 Listing of Missed Samples All samples were collected as scheduled except for those listed in Listing of Missed Samples, Appendix III.

5.7 Program Modifications There were no modifications to the program in 2004.

6.0 ANALYTICAL PROCEDURES Procedures used during the period covered in this report remained essentially unchanged.

A summary of the procedures used for analyzing radioactivity in environmental samples is given in Appendix VI of the report for the period January - December 1993.

7.0 MILCH ANIMALS AND NEAREST CATTLE CENSUS Census of milch animals and nearest cattle were conducted within a 6.2-mile radius of the station. The survey was conducted by "door-to-door" canvas by A. Lewis on August 31, 2004. Results of the milch animal and nearest cattle census are presented on pages 38 and 39, Section 5.0 of Appendix III.

There are no dairy farms within a 6.2-mile radius of the Dresden Nuclear Power Station.

8.0 NEAREST RESIDENCES CENSUS The nearest resident census was conducted by A. Lewis on August 31, 2004. Results of the nearest resident census are presented page 40, Section 5.0 of Appendix III.

9.0 DREDGE SPOILS RESULTS According to the Army Corp. of Engineers in August 2004, there was no dredging done during the year.

1.0 INTRODUCTION

The following constitutes the 2004 Progress Report for the Radiological Environmental Monitoring Program conducted at the Dresden Nuclear Power Station, Morris, 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, I-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.

Environmental Inc., Midwest Laboratory participates in intercomparison studies administered by Environmental Resources Associates, and serves as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

January through December, 2004 IV-2

Appendix IV Interlaboratorv 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 list results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

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.

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.

c MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP.

d The cause of the deviation seems to be incomplete dissolution of the sample.

' A spiked soil sample was prepared. Known activity; 32.98 pCi/g; laboratory result 33.47 pCi/g.

'The sample was reanalyzed with the same results. Investigation is in progress.

9 Based on the results of gamma emitting isotopes (Cs-1 37 and Co-60), the filter geometry appears to be biased by -10%. Addition of the summation peak at 1400 KeV results in a recalculation of 2.12 +/- 0.15 Bq/sample.
