I INTRODUCTION Byron Station, a two-unit PWR plant, 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 1120 MW net. Unit No.1 loaded fuel in November 1984 and went on line February 2,1985. Unit No. 2 went on line January 9,1987. The plant has been designed to keep releases to the environment at levels below those specified in the regulations.

l 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 daily grab samples of noble gases and continuously collected composite sa.nples of iodine and particulate matter. The results of effluent analyses are 7

I summarized on a monthly basis. Airborne concentrations of noble gases,1-131, and particulate i

radioactivity in offsite areas are calculated using isotopic composition of effluents and meteorological data.

I j

Environmental monitoring is conducted by sampling at indicator and control (background)

'i locations in the vicinity of Byron Station to measure changes in radiation or radioactivity levels that may be attributable to plant 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 I-131 in milk are the critical pathways at this site; however, an i

environmental monitoring program is conducted which also includes other pathways.

SUMMARY

Gaseous and liquid effluents for the period contributed to only a small fraction of the Technical Specification limits. Calculations of environmental concentrations based on effluent, Rock River flow, and meteorological data for the period indicate that consumption by the public of radionuclides attributable to plant operations are well below regulatory limits. Radiation exposure from radionuclides released to the atmosphere represented the critical pathway for the period with a maximum adult dose estimated to be 2.87E-05 mrem f or 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 resul*s of I

analysis confirm that the station is operating in compliance with 10CFR50 Appendix 1 and 40CFR190.

I There were no additional operational controls implemented which affected the areas of radiological effluents in 1994.

There were no measurements which exceeded the reporting levels, including any which would I

not have been attributable to plant effluents.

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

1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere Measured concentrations and isotopic composition of noble gases, radiciodine, and particulate radioactivity released to the atmosphere during the year are listed in Table 1.1-1. A total of 3.61E+01 curies of fission and activation gases was released with a maximum quarterly release rate of 3.70E+01 pCi/sec, for both units.

There was no I-131 or I-133 detected in gaseous effluents during the year.

A total of 4.69E-05 curies of beta emitters was released as airborne particulate matter with no alpha emitters being detected.

A total of 2.60 curies of tritium was released.

1.2 Liquids Released to Rock River I

A total of 2.52E+07 liters of radioactive liquid waste (prior to dilution) containing 6.40 curies (excluding tritium, gases and alpha) were discharged from the station. These wastes were released at a maximum quarterly average concentration of 7.95E-07 pCi/ml. A total of 1.82E+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 to Barnwell, South Carolina. The record of waste shipments is summarized in Table 2.0-1.

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

3.1.1 Noble Gases 3.1.1.1 Gamma Dose Rates Offsite Gamma air and whole body dose rates are shown in Table 3.1-1 and were calculated based on measured release rates, isotopic I

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 I

effluents and average meteorological data, the maximum dose to an individual would be 2.87E-05 mrem for the year, with an occupancy or shielding factor of 0.7 included, and based on measured effluents and concurrent meteorological data would be 1.18E-03 mrem. The maximum gamma air dose was 4.01E-05 mrad, and 2.11E-03 mrad based on concurrent meteorological data.

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 g

few meters or less); consequently, plumes olgaseous effluents may be g

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 because this depends on 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 mg/cm2 and an occupancy factor of 1.0 is used. This skin dose from beta and gamma radiation for the year was 7.72E-05 mrem.

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 was 1.34E-04 mrad.

3.1.2 Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. The minimal levels of radioiodine, I-131, released during E

routine operation of the plant may be made available to man resulting in a dose E

to the thyroid. The principal pathway of interest for this radionuclide is ingestion of radiciodine in milk ay an infant. Calculations made for 1993 and g

previous years indicate that contributions to doses from inhalation of I-131 and g

I-133 and I-131 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 E

factor which accounts for the phenomenon of elemental iodine g

deposition on the ground. There were no detectable iodine releases during the year.

3.1.2.2 Dose to Infant's Thyroid The hypothetical thyroid dose to an infant living near the plant via E

ingestion of milk was calculated. The radionuclide considered was I-5 131 and the source of milk was taken to be the nearest dairy farm with the cows pastured from May through October. The maximum infant's thyroid dose was 0.00 mrem during the year (Table 3.1-1).

3.1.3 Concentrations of Particulatesin Air Concentration contours of radioactive airborne particulates are shown in Figure 3.1-4. The maximum annual offsite concentration is estimated to be 2.91E-06 pCi/m3, 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 aquatic foods, and exposure while walking on the shoreline. Not all of these pathways are significant or I

l l

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 l

use of the aquatic environment. NRC developed equations' were used to calculate the doses to the whole body, lower GI tracts, t iyroid, bone, skin; specific parameters for use in the equations are given in the Commonwealth Edison Offsite Dose Calculation Manual. The maximum whole body dose for the year was 6.40E-03 mrem and no organ dose exceeded 4.06E-02 mrem (Table 3.2-1).

3.3 Assess.nent of Dose to Member of Public 4

During the period January to December,1994, 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 RETS limits on dose or dose commitment to a member of the public due to radioactive materials in liquid effluents from each reactor unit (3 mrem to the whole body or 10 mrem to any organ during any calendar quarter; 6 mrem to the whole body or 20 mrem to any organ during any I

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 I

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 l

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).

I The 10CFR20 limit on Total Effective Dose Equivalent to individual members of the public (100 mrem).

1 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' evels.

Data recovery for all measurements on the tower was 99.9%.

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 an Appendix III.

I Specific findings for various environmental media are discussed below.

5.1 Gamma Radiation External radiation dose was measured using CaSO4:Tm thermoluminescent dosimeters (TLDs). Each location consists of 2 TLD sets. The annual average external radiation dose was 16.3 mR at the indicator locations and 14.3 mR at the control locr.tions. TLD results are listed in Section 4.0 of Appendix 111 and Jocations are shown in Figure 5.0-1.

Quarterly external radiation dose at twelve air sampling locations averaged (14.9) 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), and 1993 (14.2 mR). These differences are not statistically significant.

5.2 Airborne I-131 and Particulate Radioactivity Locations of the samplers are shown in Figure 5.0-2. Airborne I-131 remained below 3

the LLD of 0.07 pCi/m throughout the year in all samples.

Gross beta concentrations ranged from 0.006 to 0.051 pCi/m3 and averaged 0.021 pCi/m3, which is slightly lower than the average concentrations in 1985 (0.026 3

pCi/m ),1986 (0.026 pCi/m3, except for the period from May 12 through June 9 when it was influenced by the nuclear reactor accident at Chernobyl), 1987 (0.027 3

pCi/m ),1988 (0.031 pCi/m3),1989 (0.026 pCi/m3), and about the same as in 1990 3

(0.021 pCi/m3),1991 (0.020 pCi/m ),1992 (0.022 pCi/m3), and 1993 (0.021 pCi/m3),

All gamma-emitting nuclide activities were below their respective LLD levels. No radioactivity attributable to plant operation was detected in any samples.

5.3 Terrestrial Radioactivity Vegetables were collected in July, August, and September and analyzed for gamma-emitting nuclides. In addition, green leafy vegetables were analyzed for Iodine-131.

All nuclides were below the limits of detection, indicating that there was no 3

measurable amount of radioactivity attributable to the station releases. Identical E

results were obtained during the period 1985 through 1993.

5.4 Acuatic Radioactivity 1

Well water was collected monthly from two offsite wells, shown in Figure 5.0-3, and analyzed for gross beta, tritium, and gamma-emitting nuclides. All other results were E

below the lower limits of detection. The results were similar to those obtained in 1985 5

through 1993.

Surface water samples were collected weekly from four locations shown in Figure 5.0-

3. Weekly samples were composited monthly and analyzed for gamma emitters.

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.

l Tritium concentration was below the LLD of 200 pCi/L in all samples collected from t

6 m:=

the Woodland Creek (BY-09), Upstream (BY-13), and Upstream (BY-29). These icvels were similar to those obtained in 1985 through 19?3.

I Downstream from discharge (BY-12), tritium averaged 838 pCi/L, ranging from 473 to 1,391 pCi/L. Cs-134 and Cs-137 levels 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. Elevated levels of tritium downstream from discharge pipe are I

attributable to the station operation. These levels were similar to those obtained in 1985 through 1993.

I Sediment samples were collected twice, from two control and one indicator locations, 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 detected in two samples (one control and one I

indicator) and averaged 18.4 pCi/g dry weight, similar to that observed in 1991 (0.27 pCi/g dry weight),1992 (0.16 pCi/g dry weight), and 1993 (0.25 pCi/g dry weight).

l All other gamma-emitting nuclides, except naturally occurring gamma-emitters, were below detection limits.

i Levels of gamma radioactivity in fish were measured and found in all cases to be l

below the lower limits of detection for the program. The results were identical to

{

those obtained in 1985 through 1993.

5.5 Milk Milk samples were collected monthly from November through April and semimonthly from May through October and analyzed for Iodine-131 and gamma-emitting nuclides. Locations shown in Figure 5.0-4. Iodine-131 level was below the LLD level of 1.0 pCi/L in all samples.

Cs-134 and Cs-137 were below the LLD levels of 15 pCi/L and 18 pCi/L, respectively.

!3 All other gamma-emitting nuclides, except naturally-occurring K-40, were below their

! E respective LLDs. The results for I-131, Cs-134 and Cs-137 were identical to those obtained during the period 1985 through 1993, except during several months following the accident at Chernobyl, which occurred on April 26,1986. During those I

months I-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 se eduled except those listed in Listing of Missed Samples, Section 2.0 of Appendix III.

5.7 Program Modifications I

The ODCM and Figures 11-2,11-3, and 11-4 were revised to include the new TLD locations and update various sample locations. Table 11-1 was revised to include new TLD locations and update sector and distances of various sampling locations.

A more rigid definition for the quarter has been adopted for 1994. Each quarter is 13 weeks long. The week shall start on Monday and end on Sunday, with week #1 (1994) beginning on the first Monday of January (1/3/94). Due to this new definition

,I all sa mples collected prior to 1/3/94 were reported as 1993 samples.

The following TLD's were deleted in the third quarter:

7.0 MILCH ANIMALS AND NEAREST CATTLE CENSUSES Censuses of milch animals and nearest cattle were conducted within a five mile radius of the Station. The survey was conducted by " door-to-door" canvas and by information from Illinois agricultural agents. The censuses were conducted by W. Mueller on August 17 and 18,1994.

Results of the milch animal and nearest cattle censuses are presented in Table 9 of Appendix 111.

8.0 NEAREST RESIDENCES CENSUS The census of nearest residences within a five mile radius was conducted by W. Mueller on August 17,1994.

Results of the nearest residence census are presented in Table 9 of Appendix III.

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

Commonwealth Edison's Thermoluminescent Dosimeter (TLD) Program is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) which requires biennial review and evaluation. In addition to the biennial ANSI tested requirement, g

Commonwealth Edison also tests to the ANSI standard during the non-NVLAP visitation 3

year. Commonwealth Edison additionally has an internalirradiation program that tests each of the six nuclear station TLD processors once per quarter. The results of all TLD performance tests are retained by Commonwealth Edison's Corporate Health Physics Support.

1.0 INTRODUCTION

The following constitutes the final,1994 Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at Byron Station, Byron, 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, Ru-103, Ru-106, I-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. 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 xi2s;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. I All concentrations, except for gross beta, are decay corrected to the date of collection. 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.

Appendix A Interlaboratory Com_p2mfarrogram Results Teledyne Brown Engineering Environmental Services, Midwest Laboratory (formerly Teledyne Isotopes and Hazelton Environmental Services) has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are I operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides know 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 3 it to any possible problems. 3 I 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 A-1 were obtained through participation in the environmental sample crosscheck

I program for milk, water, air filters, and food samples during the current year. This program is conducted by the U.S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

I Table A-2 lists results of the analyses on in-house " spiked" samples. Table A-3 lists results of the in-house " blank" samples. Table A-4 lists results of the in-house " duplicate" program. Out-of limit results are explained directly below the result. I I 173

It states, "The Radiation Quality Assurance Program has been experiencing problems with the Ruthenium-1% currently used in the Performance Evaluation (PE) Studies and in the Standards Distribution Program. If these problems can be satisfactorily resolved, this analyte will once again be placed into this PE Study. If the problems cannot be resolved, the Ruthenium-106 will be replaced. Formal written notice will be given to all participants in the Gamma in Water PE Study before the Ruthenium-1% is reintroduced or replaced. At that time, new calibration standards will be available to all participants in the Gamma in Water PE Study." Teledyne will continue to monitor this situation, but at this time, plans to take no additional action.

All concentrations are reported in pCi/L, except solid samples, which are reported in pCi/g wet. Results reported as ActivityiCounting Error; Total Propagated Uncertainty (TPU).

6 Lab codes are comprised of the sample media and the sample numbers. Client codes have been eliminated protect client anonymity.

Acceptance is based on the difference of the two results divided by the pooled standard deviation two, where, the pooled standar ~ deviation is the square root of the sum of the squares of the TPU's.
