INTRODUCTION Units 1 and 2 of the Zion Station, located in Zion, Illinois adjacent to Lake Michigan, are 1100 MWe (3520 MWT) Westinghouse pressurized water reactors. The station has been designed to keep releases to the environment a levels below those specified in the regulations. Lic uid effluents from Zion Station are released to Lake Michigan in controlled batches after rac.ioassay of each batch and continuously through a monitored pathway. Gascous effluents are released to the atmosphere through the gas decay tanks after delay to permit decay of short-lived (noble) gases. Monitored gaseous effluents are also released through the stack and in controlied batches via vents and purges. 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 Zion Station to measure changes in radiation or radioactivity levels that may be attributable to station operations. If significant changes attributable to Zion Station are measured, these changes are correlated with effluent releases. External gamma radiation exposure from noble gases and intemal 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 other pathways. Comed is in the process of implementing a Uniform Radiological Environmental Monitoring Program, referred to as UREMP, among the Comed nuclear stations. This program includes generic requirements pertaining to environmental sampling and analysis, an annual land use census, an interlaboratory comparison program and environmental reports. Zion Station implemented UREMP on 09-29-96. I

SUMMARY

Gaseous and liquid effluents for the period contributed to only a small fraction of the Zion Station Technical Specification limits. Calculations of environmental concentrations based on effluent and meteorological data for the period indicate that consumption by the public of radionuclides attributable to the Zion 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 2.24E-03 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 Comed Offsite Dose Calculation Manual (ODCM). The results of analysis confirm that the station is operating in compliance with 10CFR50 Appendix 1, 10CFR20 and 40CFR190. 2

1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere Measured concentrations and isotopic composition of noble gases, radioiodine, and particulate radioactivity released to the atmosphere during the year, are listed in Table 1.1-1. A total of 4.63E+01 curies of fission and activation gases was released with a maximum average release rate of 2.86E+00 pCi/sec during any one quarter period. A total of 3.21E-04 curies of I-131 was released during the year with a maximum average quarterly release rate of 1.51E-05 pCi/sec. A total of 1.63E-03 curies of beta-gamma emitters was released as airborne particulate matter with a maximum average quarterly release rate of 1.46E-04 pCi/sec. Alpha-emitting radionuclides were not measurable. Also,2.85E+02 curies of tritium were released with a maximum average quarterly release rate of 2.66E+01 pCi/sec. 1.2 Liquids Released to Lake Michigan A total of 2.64E+07 liters of radioactive liquid wastes containing 8.90E-01 curies (excluding tritium, noble gases and alpha) was discharged from the station after dilution with a total of 4.90E+10 liters of water. These wastes were released at a maximum quarterly average concentration of 4.33E-08 pCi/ml. A total of 1.27E+03 curies of tritium and 4.90E-04 curies of alpha radioactivity were released. Monthly release estimates 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 Barnwell, South Carolina; Memphis, Tennessee; and Oak Ridge, Tennessee. 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 airborne radioactivity via the different exposure pathways. 3.1.1 Noble Gases 3.1.1.1 Ganuna Dose Rates Offsite Gamma air and whole (total) 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 meteorological data for the period. 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 average meteorological data, the maximum dose to an individual would be 2.24E-03 mrem for the year, with an occupancy or shielding factor of 0.7 included, and based on measured effluents and 3

I meteorological data would be 2.00E-04 mrem. The maximum gamma g air dose was 3.23E-03 mrad based on measured effluents and average 5 meteorological data, and 2.06E-04 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 few meters or less); consequently, plumes of gaseous effluents may be considered " infinite" for purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive 3 skin tissues is difficult to calculate due to the effect of the beta particle 3 energies, thickness of inert skin and clothing covering sensitive tissues. For pur oses of this report the skin is taken to have a thickness 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 1.03E-02 mrem. The air concentrations of radioactive noble gases at the offsite receptor locations are given in Figure 3.1-2. ihe maximum offsite beta air dose for the year was 2.28E-02 mrad. 3.1.2 Radioactive lodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. The radiciodine, I-131, released during routine operation of the station, may be made available to man resulting in a dose to the thyrdid. The principal pathway of interest for this radionuclide is ingestion of radiciodine in milk by an infant. 3.1.2.1 Iodine Concentrations in A.ir The calculated concentration contours for I 131 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 offsite concentration is 3 estimated to be 1.85E-04 pCi/m for the year. i 3.1.2.2 Dose to Infant's Thyroid The hypothetical thyroid dose to an infant living near the station via ingestion of milk was calculated. The maximum infant's thyroid dose g' due to I-131 was 1.87E-01 mrem during the year (Table 3.1-1). g ) ' ulates in Air 3.1.3 Concentration-li Concentration contours of radioactive airborne particulates are shown in Figure 3.1-4. The maximum offsite level is estimated to be 3.35E-04 pCi/m, 3 3.2 Liquid Effluent Pathways The three principal pathways through the aquatic environment for potential doses to g man from liquid waste are ingestion of potable water, eating aquatic foods, and g exposure while walking on the shoreline. Not all of these pathways are significant or 4 I

q 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 use of the aquatic environment. NRC developed equations

were used to calculate the doses to the whole body, lower GI tracts, thyroid, bone, skin; specific parameters foc use in the equations are given in the Comed Offsite Dose Calculation Manual.

The maximum whole body dose (total body) for the year was 1.55E-03 mrem and no organ dose exceeded 2.27E-03 mrem (Table 3.2-1). 3.3 Assessment of Dose to Member of Public During the period January to December,1996, Zion Station did not exceed these limits as shown in Table 3.1-1 and Table 3.2-1, (based on yearly average meteorological data), Figure 3.1-1 (based on concurrent meteorological data), and Table 3.1-1: The RETS limits on dose or dose commitment to an individual 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 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 pa'rticulate 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 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 35' evels. Data recovery for these measurements was about 99.0% during 1996. 5.0 ENVIRONMENTAL MONITORING Table 5.0-1 provides an outline of the Radiological Environmental Monitoring Program (REMP) as required in current Technical Specifications. Tables 5.0-2 provides program sampling locations, sample collection frequencies and analyses for all samples. Tables 5.0-3 to 5.0-6 summarize data for the year.

Except for tables of special interest, tables listing all data are no longer included in the annual report. All data tables are available for inspection at the Station. Specific findings for various environmental media are discussed below. 5.1 Gamma Radiation 1 External radiation dose was measured using CaSO4:Tm thermoluminescent gI dosimeters (TLDs). Each location normally consists of 2 TLD sets. The quarterly B l average external radiation dose for the year was 13.8 mR at the indicator locati_ons and 14.7 mR at the control (background) locations. TLD results are listed in Table 5.1-1 and locations are shown in Figures 5.0-1 and 5.0-2. j Quarterly external radiation dose at thirteen air sampling locations averaged 13.1 mR and was slightly lower than the levels measured in 1985 (14.7 mR),1986 (15.5 mR), 1987 (15.2 mR),1988 (14.3 mR),1989 (14.1 mR),1990 (14.8 mR), and similar to those in 1991 (12.5 mR),1992 (11.6 mR),1993 (12.5 mR),1994 (12.5 mR) and 1995 (12.7). These differences are not statistically significant. 1 5.2 Airborne I-131 and Particulate Radioactivity Locations of the air samplers are shown in Figure 5.0-3. Airborne I-131 remained 3 below the LLD of 0.07 pCi/m throughout the year. ) Gross beta concentrations ranged from 0.007 to 0.043 pCi/m3 and averaged 0.020 pCi/m and were similar to those in 1985 (0.02 pCi/m ),1986 (0.023 pCi/m3, except 3 3 for the period from May 13 through June 10 when it was influenced b the nuclear 3 reactor accident at Chernobyl),1987 (0.020 pCi/m ),1988 (0.025 pCi/m ),1989 (0.022 pCi/m3),1990 (0.018 pCi/m ),1991 (0.018 pCi/m ),1992 (0.019 pCi/m3),1993 (0.020 3 3 3 3 pCi/m ),1994 (0.019 pCi/m3) and 1995 (0.018 pCi/m ), No activity attributable to station operation was detected in any sample. 5.3 Aquatic Radioactivity Water samples were collected weekly from six public water works that draw water from Lake Michigan. (The number was reduced to four public water works upon El implementation of UREMP in the fourth quarter of 1996. See Program Modifications, gi Section 5.7.) Monthly composites of the samples were analyzed for gamma emitters and quarterly composites for tritium. Gross beta analysis was added to the monthly composites in the fourth quarter of 1996 upon UREMP implementation. Gamma emitters were in all cases below the lower limits of detection for the program. Tritmm was below the LLD level of 200 pCi/L in all samples. Similar results were obtained in 1985,1986,1987,1988,1989,1990,1991,1992,1993,1994 and 1995. Gross beta activity 3 was below the LLD level of 4 pCi/L. in all but the November 1996 composite from Z-3 16 (Waukegan Water Works) which showed an activity of 5.2 pCi/L. Cooling water samples were collected weekly and analyzed for gross beta. Quarterly composites were analyzed for tritium. All samples contained gross beta activity in the range to be expected in cooling water samples. The gross beta concentration I II 6 I

l averaged 2.2 pCi/L at the intake and 2.3 pCi/L at the discharge; the differences are not statistically significant. l Cooling water sample Z-22 (Unit 1 Inlet) tritium activity was above the required LLD B level in the first and third quarters with levels of 207 pCi/L and 229 pCi/L, respectively. Z-23S (Unit 1 Discharge) and Z-23N (Unit 2 Discharge) showed third quarter activities of 284 pCi/L and 231 pCi/L, respectively. All other results were I below LLD. Fish samples were collected from the vicinity of the station, and the edible portions analyzed for gamma emitters. Concentrations of radioactivity in these samples were below the lower limits of detection for the program. Similar results were obtained in i 1985,1986,1987,1988,1989,1990,1991,1992,1993,1994 and 1995. Sediment samples were collected near site of Illinois Beach State Park and analyzed for g:auna emitters. Gamma radiosctivity was below the limit of detection. 5.4 Milk Milk samples were collected monthly from January through April and biweekly from I May through September. Milk sampling was discontinued in the fourth quarter of 1996 upon implementation of UREMP. The samples were analyzed for I-131 by high-sensitivity methods (iodine chemistry and low level beta counting). Radiciodine remained below the limits of detection of 1.0 pCi/L and gamma radioactivity I remained below the lower limits of detection for the program. 5.5 Terrestrial Activity B Vegetables were collected from one indicator location in September and analyzed for gamma-emitters. All levels were below the respective LLDs. Also, broad leaf l vegetables were analyzed for I-131; all samples were below the required LLD of 0.6 l pCi/g wet weight. 5.6 Sample Collections All samples were collected as scheduled except those listed in the Listing of Missed Samples, Appendix III. 5.7 Program Modifications On June 29,1996 TLDs were installed at locations Z-101-1 and Z-101-2. On September 29,1996 Zion Station implemented UREMP and the following changes were made: Air sampling stations Z-04 (Zion W), Z-07 (Winthrop Harbor Marina Drive), Z-10 (North Chicago), Z-12 (Flood Farm) and Z-13 (Pleasant Prairie DC) were deleted. The remaining samplers were organized into nearsite locations, farsite locations and a control location. TLDs locations Z-102-1 and 102-2 were activated. Public water sampling points Z-17 (North Chicago Water Works) and Z-19 (Great Lakes Naval Training Center Water Works) were dropped from the program. Gross 7

I beta analysis was added to the monthly composites for all remaining public water locations. Milk locations Z-27 (Doolittle Farm) and Z-29 (Kevek Dairy) werd deleted. The indicator location designation for fish collection (Lake Michigan Nearsite) was changed from Z-24 to Z-26. Controllocation Z-27 (Lab Michigan Farsite) was added to the program. Annual vegetation collection from indicator locations in the two quadrants over land, as well as from one control location,is now a requirement. 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 VII 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 A. Green on August 24 and August 17,1996, respectively. Results of the milch animals and nearest cattle census are presented in Appendix IV. There are no milk producing animals within a 6.2-mile radius of Zion Station, i 8.0 NTAREST RESIDENCE CENSUS A census of the nearest residences within a 6.2-mile radius was conducted by A.

4 Apoendir V Interlaboratory Comparison Pmeram 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 its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing l concentrations of radionuclides know to the issuing agency but not to participant laboratories. He purpose cf 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 c.d n / ort them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories rnd specifies control limits. Results consistently higher or lower than the known values or outside the l contmllimits indicate a need to check the instruments or procedures used. l l De results in Table A-1 were obtained through participation in the environsrental sample crosscheck program for milk, water, air filters, and food samples during the current year.'Ihis program is conducted the U.S. Environmental Protection Agency Office of Research and Developement National Exposure l Research Laboratory Characterization Research Division-las Vegas, Nevada. Table A-2 lists results of the analyses on in-house " spiked" samples. 1 i Table A 3 lists results of the in-house " blank" samples.

APPENDIX VII ERRATA DATA J l I I i I 4 i VII-l

ERRATA DATA 1.0 On March 6,1997,'during a review of Commonwealth Edison's current ODCM, it was discovered that since 1991, when Comed began processing its environmental TLDs in-house, Comed has not been performing an inter' aboratory comparison program to assess measurements of environmental radiation for those TLDs. This is required by section 5.3.1 of the ODCM. Corrective action began with the second quarter of 1997, during which Comed populated Zion Station's direct radiation environmental locations with its own environmental TLDs as well as with TLDs supplied by a vendor. Zion's environmental TLDs were placed in the field on March 30,1997. Due to short notice given to the - vendor to supply Comed with their TLDs, the vendor's TLDs were placed in the field on April 5,1997. (The vendor's environmental TLD program does comply with section 5.3.1 of Comed's ODCM.) Comed will develop an interlaboratory comparison program for its own environmental TLDs and will commence interlaboratory comparison as soon as its program is satisfactorily developed. The TLD record for environmental monitoring will be Zion's TLDs, provided Comed has successfully implemented the interlaboratory comparison program. Otherwise, the vendor's TLDs will be Comed's dose of record, and the dose to the vendor's TLDs for the period from March 30 to April 5,1997 will be estimated. VII-2}}
