INTRODUCTION Byron Station, a two-unit PWR station, is located about two miles east of the Rock River and approximately three miles southwest of Byron in Ogle County, north central Illinois. Each reactor is designed to have a capacity of 1165 MW net. Unit No. I loaded fuel in November 1984 and went on line February 2, 1985. Unit No. 2 went on line January 9, 1987. The station has been designed to keep releases to the environment at levels below those specified in the regulations.

Liquid effluents from Byron Station are released to the Rock 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 weekly grab samples and grab samples of batch releases prior to the release 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.

Airborne concentrations of noble gases, 1-131, and particulate radioactivity in offsite areas are calculated using isotopic composition of effluents and meteorological data.

Environmental monitoring is conducted by sampling at indicator and control (background) locations in the vicinity of Byron Station to measure changes in radiation or radioactivity levels that may be attributable to station operation. If significant changes attributable to Byron 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 critical pathways at this site; however, an environmental monitoring program is conducted which also includes other pathways.

1

SUMMARY

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

The Total Effective Dose Equivalent (TEDE) due to licensed activities at Byron Station calculated for the maximally-exposed individual for the period is 6.04E-03 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 10CFR50 Appendix I, IOCFR20 and 40CFR190.

There were no additional operational controls implemented which affected the areas of radiological effluents in 2001.

There were no measurements which exceeded the reporting levels, including any which would not have been attributable to station effluents.

The results of the current radiological environmental monitoring program are approximately the same as those found during the pre-operational studies conducted at Byron Station.

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

A total of 1.75E+00 curies of fission and activation gases were released with a maximum quarterly release rate of 4.27E+00 [Ci/sec, for both units.

A total of 0.OOE+00 curies of 1-131 were released during the year with a maximum quarterly average release rate of 0.OOE+00 gCi/sec.

A total of 9.68E-06 curies of beta emitters were released as airborne particulate matter with a maximum quarterly average release rate of 8.85E-07 [tCi/sec. Alpha-emitting radionuclides were below detectable limits.

A total of 6.82E+00 curies of tritium were released with a maximum average quarterly release rate of 3.65E-01 RCi/sec.

1.2 Liquids Released to Rock River A total of 1.17E+07 liters of radioactive liquid waste (prior to dilution) containing 2.85E-01 curies (excluding tritium, noble gases and alpha) were discharged from the station. These wastes were released at a maximum quarterly average concentration of 1.51E-08 ItCi/ml.

A total of 1.21E+03 curies of tritium was released.

Quarterly release totals of 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 Barnwell disposal facility or to waste processors. For detail, refer to Byron Station 2001 Effluent 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 GammaDoseRates Offsite gamma air and whole body dose rates are shown in Table 3.1-1 and were calculated based on measured release rates, isotopic 3

composition of the noble gases, and average meteorological data for the period. Isodose contours based on concurrent meteorological data for gamma dose are shown in Figure 3.1-1 for the year. Based on measured effluents and average meteorological data, the maximum total body dose to an individual would be 6.07E-06 mrem for the year (Table 3.1-1), 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 7.68E-06 mrem (Table 3.4-1). The maximum gamma air dose was 8.48E-05 mrad (Table 3.1-1) based on measured effluents and average meteorological data, and 5.99E-06 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 taken to have a thickness of 2

7.0 mg/cm and an occupancy factor of 1.0 is used. The skin dose from beta and gamma radiation for the year, based on measured effluents and average meteorological data, was 1.58E-05 mrem (Table 3.1-1).

The skin dose based on concurrent meteorological data was 1.45E-05 mrem (Table 3.4-1).

The air concentrations of radioactive noble gases at the offsite receptor locations are given in Figure 3.1-2. The maximum offsite beta air dose for the year, based on measured effluents and average meteorological data, was 2.76E-05 mrad (Table 3.1-1).

The beta air dose based on concurrent meteorological data was 9.49E-06 mrad (Table 3.4-1).

3.1.2 Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. The minimal levels of radioiodine, 1-131, 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 for 2001 and previous years indicate that contributions to doses from inhalation of 1-131 and 1-133 and ingestion of 1-133 in milk are negligible.

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 4

factor which accounts for the phenomenon of elemental iodine deposition on the ground. The maximum offsite concentration is estimated to be 3.66E-07 pCi/mn3 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 was less than 4.13E-03 mrem during the year (Table 3.1-1 [child]).

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 2.97E-01 pCi/m3 (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 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 GI tract, thyroid, bone and 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 4.84E-03 mrem (child) and no organ dose exceeded 6.56E-03 mrein (Table 3.2-1 [adult]).

3.3 Assessment of Dose to Member of Public During the period January to December, 2001, Byron 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 (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 whole body or 5 mremn to any organ during any calendar quarter;

Nuclear Regulatory Commission, Regulatory Guide 1.109 (Rev. 1).

5

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 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).

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 250' level and wind speed class by atmospheric stability class determined from the temperature difference between the 250' and 30' levels.

Data recovery for all measurements on the tower was 99.8% during 2001 (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 Technical Standards.

Table 5.0-2 outlines the sampling locations, sample collection frequency and analysis for the samples. Sampling locations are shown in Figures 5.0-1 through 5.0-4. Concentrations of radioactivity in various media are summarized in Tables 5.0-3 through 5.0-6.

A detailed listing of all data is presented in Appendix III.

Specific findings for various environmental media are discussed below.

5.1 Gamma Radiation External radiation dose was measured using CaF2 thermoluminescent dosimeters (TLDs) processed by an off-site vendor. Previous year data had been acquired using CaSO4 dosimeters processed in-house. Each location consists of 2 TLD sets. The quarterly average external radiation dose for the year was 19.9 mR at the indicator locations and 17.1 mR at the control locations. TLD results are listed in Section 4.0 of Appendix III and locations are shown in Figure 5.0-1.

6

Quarterly external radiation dose at indicator air sampling locations averaged 19.2 mR and was similar to that measured in 1985 (14.4 mR), 1986 (14.9 mR), 1987 (15.3 mR),

1988 (15.2 mR), 1989 (14.6 mR), 1990 (14.5 mR), 1991 (14.3 mR), 1992 (13.6 mR),

1993 (14.2 mR), 1994 (14.9 mR), 1995 (14.9 mR), 1996 (15.4 mR), 1997 (13.8 mR),

1998 (14.7 mR), 1999 (13.9 mR) and 2000 (14.4 mR). These differences are not statistically significant and may be attributed to the different style of TLD used to measure gamma radiation.

5.2 Airborne 1-131 and Particulate Radioactivity Locations of the samplers are shown in Figures 5.0-2 and 5.0-3.

Airborne 1-131 remained below the LLD of 0.07 pCimi3 throughout the year in all samples.

Gross beta concentrations ranged from 0.004 to 0.054 pCi/n3 and averaged 0.024 pCi/m3, which is slightly lower than the average concentrations in 1985 3

3 (0.026 pCimi), 1986 (0.026 pCi/in), except for the period from May 12 through June 9, when it was influenced by the nuclear reactor accident at Chernobyl), 1987 3

~33 (0.027 pCi/m 3), 1988 (0.031 pCi/mr), 1989 (0.026 pCi/m 3), and similar to 1990 333 3

(0.021 pCi/m3), 1991 (0.020 pCi/mi), 1992 (0.022 pCi/m), 1993 (0.021 pCi/im), 1994 (0.021 pCim 3), 1995 (0.022 pCi/m3), 1996 (0.022 pCi/m3), 1997 (0.021 pCi/m3), 1998 (0.022 pCi/in3), 1999 (0.025 pCi/m3) and 2000 (0.025 pCi/m3).

All gamma-emitting nuclide activities were below their respective LLD levels.

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

5.3 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 that there was no measurable amount of radioactivity attributable to the station releases. Identical results were obtained during the period 1985 through 2000.

5.4 Aquatic Radioactivity Well water was collected quarterly from three offsite wells, shown in Figure 5.0-4, and analyzed for tritium and gamma-emitting nuclides. All results were below the lower limits of detection. The results were similar to those obtained in 1985 through 2000.

Surface water samples were collected weekly from two locations noted in Figure 5.0-4.

Weekly samples were composited monthly and analyzed for gross beta and gamma.

Quarterly composites were analyzed for tritium. Cs-134 and Cs-137 concentrations were below the LLD level of 15 pCi/L and 18 pCi/L, respectively, in all samples. All other gamma-emitters were below their respective LLDs.

Gross beta at BY-12 (Oregon Pool of Rock River, Downstream) averaged 3.3 pCi/L, ranging from 7

1.7 to 4.1 pCi/L; BY-29 (Byron, Upstream) gross beta averaged 3.3 pCi/L, ranging from 2.0 to 5.8 pCi/L.

Tritium concentration was below the LLD of 200 pCi/L in all samples collected from Byron, Upstream (BY-29).

These levels were similar to those obtained in 1985 through 2000.

At Oregon Pool of Rock River, Downstream (BY-12) tritium averaged 2,373 pCi/L, ranging from 1,708 to 3,618 pCi/L.

Elevated levels of tritium downstream from discharge pipe are attributable to the station operation. These levels were similar to those obtained in 1985 through 2000.

Sediment samples were collected twice and analyzed for gamma-emitters. Cs-134 was below the LLD level of 0.15 pCi/g dry weight in all samples. Cs-137 was below the LLD level of 0.18 pCi/g dry weight in all samples.

Levels of gamma radioactivity in fish were measured and found in all cases to be below the lower limits of detection for the program. The results were identical to those obtained in 1985 through 2000.

5.5 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.

Locations are shown in Figure 5.0-4. Iodine-131 activity was below the LLD level of 0.5 (May through October) and 5.0 (November through April) pCi/L in all samples.

Cs-134, Cs-137 and Ba/La-140 were below the LLD levels of 15, 18 and 15 pCi/L, respectively. The results for 1-131, Cs-134, Cs-137 and Ba/La-140 were identical to those obtained during the period 1985 through 2000, except during several months following the accident at Chernobyl, which occurred on April 26, 1986. During those months 1-131 ranged from 0.9 to 58.6 pCi/L, Cs-134 ranged from 5.8 to 10.7 pCi/L and Cs-137 ranged from 5.3 to 17.8 pCi/L.

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

5.7 Program Modifications New well water location, BY-14-1, 3200 German Church Road, replaced former location, BY-14, ComEd Offsite Well, in August of 2001.

1.0 INTRODUCTION

The following constitutes the current 2001 Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at the Byron Station, Byron, 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, 1-131, Ba/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 Sample Type Location Collection Comments Code Date None for 2001.

Collector removed pump #128 because of low vacuum; placed pump #102.

Collector gaskets lost in mail; could not exchange on 04-03-01. New gaskets were sent and collector exchanged on 04-10-01.

Pump motor running; vacuum and flowrate readings zero.

Collector replaced pump.

Collector unable to obtain sample; pump would not produce water. Will try to collect next collection period.

Collector could not obtain well water; pump not working.

NOTE: New location (BY-14-1) found 08-21-01.

High meter reading of 191.0 believed due to timer "reset" during pump rewiring; used 159.8 hrs for calculations.

Low meter reading of 110.9 believed due to timer "reset" during pump rewiring; used 159.8 hrs for calculations.

APPENDIX IV INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE: Environmental Incorporated Midwest Laboratory participates in intercomparison studies administered by Environmental Resource Associates which serve as a replacement for studies previously conducted by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported annually in Appendix IV. Also reported are results of mixed analyte and Environmental Measurements Laboratory performance evaluation programs.

January, 2001 through December, 2001

Appendix IV Interlaboratory Comparison Program Results Enviromental Incorporated Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control pvogram in December 1971.

These programs are operated by agencies which supply environmental type samples (e.g., milk or water) 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 the laboratory's analytical procedures and to alert it to 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.

The results in Table IV-1 were obtained through participation in the environmental sample crosscheck program for milk, water, air filters, and food samples through December 31, 2001. This program was conducted by Environmental Resource Associates and serves to replace studies formerly conducted by the U.S. Environmental Protection Agency Office of Research and Development, National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.

Table IV-2 lists results of the mixed analyte performance evaluation program.

Table IV-3 lists results of the Environmental Measurement Laboratory Quality Assessment Program.

" The Environmental Measurements Laboratory Vegetation and Water.

provides the following nuclear species : Air Filters,

Soil, b Results are reported in Bq/L with the following exceptions: Air Filter results are reported in Bq/Filter, Soil results are reported in Bq/Kg, Vegetation results are reported in Bq/Kg.

c The EML result listed is the mean of replicate determinations for each nuclide+/-the standard error of the mean.

"The control limits are reported by EML as the ratio of Reported Value / EML value and are established from percentiles of historic data distributions (1982-1992). The evaluation of this historic data and the development of the control limits is presented in DOE report EML-564.
