INTRODUCTION Zion Station, adjacent to Lake ' Michigan in Zion, Illinois, consists .of two Westinghouse pressurized water reactors, each with a generating capacity of 1100 MWe (3250 MWT) at full power. The Zion plant has been designed to minimize radioactive releases to the environment. The Technical Specifica-tions limit radionuclide releases to values that will-insure that. radiation ~

doses attributable.to the operation of the plant will satisfy the "as low as practicable" philosophy.

Various environmental samples are collected at indicator and. background locations and analyzed to determine if changes in radioactivity levels may be attributable to the operation of the plant. If significant changes due to the plant operation are measured, these changes _ are correlated- with effluent releases. The results of these analyses.are summarized on a monthly. basis and reported to the Nuclear Regulatory Commission annually.

SUMMARY

Gaseous and liquid effluents - for the period remained below the Technical Specification limits. . Calculations of environmental concentrations based on effluent and meteorological data for the period indicate that consumption by~

the public of radioactive materials attributable to the . plant are unlikely to exceed regulatory limits. Gamma radiation exposure from noble gases released to the atmosphere represented the critical pathway for the period with a maximum individual dose estimated to be 0.044 mrem for the year, when a shielding and occupancy factor of 0.7 is assumed. The assessment of radiation doses are performed in- accordance with the Offsite Dose Calculation Manual (0DCM). The results of analysis confirm that the station is operating in compliance with 10CFR50 Appendix I and 40 CFR 190.

1. 0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere l Measured concentrations and isotopic composition of noble gases,-

radiciodine, and particulate radioactivity released to the atmos-  ;

phere during the year, are listed in Table 1.~1-1. A total of l 3.81 E+03 curies of noble gases was released with a maximum release l rate of 8.7 E+03 pCi/sec during any one-hour period.

A- total of 1.86 E-03 curies of I-131 was released during the year.

A total of 2.29 E-02 curies of beta-gamma emitters and 4.07 E-03 j curies of alpha emitters was released as airborne particulate I matter. Also, -1.86 E+01 curies of tritium was released.

1. 2 Lifuids ~ Released to Lake Michigan A cotal of 2.27 E+08 liters of radioactive liquid wastes containing 2.37 curies (excluding tritium) were discharged from the station.

These wastes were released at a maximuin monthly average concentra-tion of 5.8 E-08 pCi/ml which is 0.076% of the Technical Specifica-tion release limits for unidentified radioactivity. During the same period, 6.56 E+02 curies of tritium and 1.12 E-03 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 RADI0 ACTIVE WASTES Solid radioactive wastes were shipped to Richland, Washington; Hanford, Washington; Beatty, Nevada; and/or Barnwell - Nuclear Center, South Carolina. The record of waste shipments is sunmarized in Table 2.0-1.

3. 0 DOSE TO MAN 3.1 Gaseous Effluent Pathways Gamma Dose Rates Gamma air and whole body dose rates off-site were calculated based on measured release rates, isotopic composition of the noble gases, i and meteorological data for the period (Table 3.1-1). Isodose contours of whole body dose are shown in Figure 3.1-1 for the year.

Based on measured effluents and meteorological data, the maximum dose to an individual would .be 0.044 mrem for the year, with an occupancy or shielding factor of 0.7 included. The maximum gamma air dose was 0.15 mrad.

3

Beta Air and Skin Rates The range of beta particles in air is relatively small (on the order of a few meters o'r 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 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 mg/cm2 and an occupancy factor of 1.0 is used. The skin dose from beta and gamma radiation for the year was 0.41 mrem.

The air concentrations of radioactive noble gases at the off-site receptor locations are given in Figure 3.1-2.

The' maximum off-site beta air dose for the year was 0.85 mrad.

Radioactive Iodine The human thyroid ~ exhibits a significant ' capacity to concentrate ingested or inhaled iodine, and the radiolodine, I-131, released during routine operation of the plant, may be made available to man thus resulting in a dose to the thyroid. 'The principal pathway of interest for this radionuclide is ingestion of radioiodine in milk l by an inf ant. Calculations made in previous years indicate that

) contributions to doses from inhalation of I-131 and I-133, and I-133 in milk are negligible.

Iodine-131 Concentration in Air 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 off-site average concentration is estimated to ' be 6.59 E-04 pCi/m3f or the year.

Dose to' Infant's Thyroid The hypothetical thyroid dose to an infant living near the plant via ingestion of milk was calculated. The radionuclide considered was I-131 and the source of milk was taken to be the nearest dairy f arm with the cows pastured from May to October. The maximum infant's thyroid dose was 7.82 E-03 ' mrem during the year (Table 3.1-1).

Concentration of Particulates in Air Concentration contours of radioactive airborne particulates are shown in Figure 3.1-4. The. maximum off-site average level is estimated to be 5.16 E-03 pCi/m3, 4

Summary of Doses

/

Table 3.1-1 summarizes the doses resulting from releases of air-borne radioactivity via the different exposure _ pathways.

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 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 Commonwealth Edison 0ffsite Dose Calculation Manual. The. maximum whole body dose for the year was

- 5.92 E-03 mrem and no organ dose exceeded 7.71 E-03 mrem.

4.0 SITE METEOROLOGY A summar'y of the site meteorological measurements taken during each l calendar quarter of the year is given in Appendix II. The cumula- 1 tive joint frequency distributions were based on the 250' level wind speed and the differential temperature between the 250' ' and 35' levels. Data recovery for all tower measurements for the year was 99.7%.

5.0 ENVIRONMENTAL MONITORING Table 5.0-1 provides an outline of. the radiological environmental monitoring program as required in current Technical Specifications.

This program went into effect in November 1977 and differs from previous programs in the number and types of analyses performed.

Tables 5.0-2 to 5.0-5 summarize data for the year. l Except for tables .of special interest, tables listing all data are no longer included in the annual report ~.. All data tables are I available for inspection at the Station or in the Corporate Offices.

Specific findings for various environmental media are discussed bel ow.

5.1 Gama Radiation External radiation dose from on-site sources and noble gases re-leased to the atmosphere was measured -at nine indicator. and four reference (background) locations using . solid lithium. fluoride

~

thermoluminescent dosimeters (TLD). A comparison of_the TLD results-I for' reference locations 'with indicator locations is included . in i

' Table 5.'l-1. Additional TLDs,-. a -total-'of 27, . were installed- on June 1,1980, such that each . land sector. was covered at~ both five miles and the site boundary.

~

1 5.2 Airborne I-131 and Particulate Radioactivity Concentrations of airborne . I-131 and particulate radioactivity at monitoring locations are sumarized in Tables 5.0-2 through 5.0-5.

Locations of the samplers are shown in Figure 5.0-1. Airborne I-131

. remained below the LLD of 0.10 pCi/m3 throughout the year.

Gross beta concentrations ranged from 0.01 to 0.14 pCi/m3 at indi-cator locations with an average concentration of 0.02 pCi/m3 No radioactivity attributable to station operation was . detected in any l 4

sample.

1 5.3 Aquatic Radioactivity l

Water samples were collected weekly from six public water works w that draw water from Lake Michigan. The samples were composited and analyzed monthly for gama emitters and quarterly for -tritium.

Gama emitters were in all cases below the limits of detection for the program, and - tritium concentrations were within the ranges expected in environmental water.

i Cooling water samples were collected weekly, . composited, and ana-lyzed for gross beta and tritium-concentrations. All samples contained both gross beta activity and tritium in concentrations in the range to be expected in environmental samples.

Fish samples were collected from the vicinity of the station, and

, the edible portions analyzed - for gama emitters. Concentrations of radioactivity :in.'these samples were below the limits of detection for the program indicating the presence of no radioactivity due to station operation.

'. A sediment . sample _ was collected near site off' lllinois Beach State

. Park and analyzed for gamma emitters. Gama radioactivity was below the limit of detection.

I

5. 4 Milk Milk samples were collected monthly f rom November through April, and weekly the rest of the year. 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 0.5 pCi/l during the grazing period (May - October) and 5.0 pCi/l during the non-gra;:ing period (November - April). The samples were analyzed for gamma emitters 'beginning in ,0ctober, 1985. Gamma radioactivity was below the limit of detection.

6. 0 ANALYTICAL PROCEDURES A description of the procedures used for analyzing radioactivity in environmental samples is given in Appendix III.

7. 0 MILCH ANIMAL CENSUS There are no milk-producir g animals within a five-mile radius of the Zion Generating Station. The closest dairy animals on record are those at Ames'tead Dairy (Z-20), located just over five miles at 270*. As of August 1985 the dairy had 56 cows. This information was obtained through the Agricultural Extension office in Grayslake, Illinois, and interviews with the manager.of Amestead Farm, and the milk pickup driver.

8.0 NEAREST RESIDENT CENSUS A nearest resident census was conducted in August 1985. The locations of nearest residences remained unchanged from previous census.

9. 0 INTERLABORATORY COMPARIS0N PROGRAM RESULTS-Teledyne Isotopes Midwest Laboratory has participated in 'interlaboratory.

comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agen-cies which supply environmental-type samples (e.g. . . milk or w~ater) 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 concentrations of specified radio -

nuclides 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.

7

j The results in Table A-1 were obtained through participation in t%

environmental sample crosscheck program for milk, water, air filters, ano food samples during the period 1982 through 1985. This program has been.

conducted by the U. S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Moni-toring and Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) during the period 1976, 1977 1979, 1980, and 1981 through participation in the Second, Third, rourth, and Fifth International Intercomparison of Environmental Dosimeters under the spnnsorships listed in Table A-2.

3. Gamma scan fillet without delay or store in a freezer.

4. After gamma spectroscopic analysis is completed transfer the sample to a drying pan and dry at 125* C.

5. Cool, weigh, and record dry weight.

6. Ash by gradually increasing the temperature to 450* C. If consider-able amounts of carbon remain after . overnight ashing, the sample should be brushed and placed back in the muffle furnace until ashing is completed. Record ash weight. The sample is now ready for analysis.

NOTE: If there is sufficient quantity, use surplus flesh for drying and ashing, instead of waiting for gamma scanning to be completed.

l L.JT. fiuebner 1.3 Drinking (clear) water (EPA Method 900.0)

A representative sample must be collected from a. free-flowing source of drinking water, and should be large enough so that- adequate aliquots can be taken to obtain.the required sensitivity.

It is recommended that sanples be preserved at the time of collec-tion by adding enough IN_ HNO3 to the sample to bring it to pH 2 (15 ml IN HNO3 per liter of sample is usually' sufficient) .If samples aie to be collected without preservation, they should be brought to the laboratory within 5 days, then preserved and held in the original ~ container for a minimum of 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> before analysis or transfer of the sample.

The container choice should be plastic over glass to prevent loss due to breakage during transportation and handling.

If the sample was not acidified at the time of collection, use the following procedure:

Procedure

1. Remove 100 ml of sample for tritium. analysis, if required.

NOTE: Water should not be acidified for tritium analysis. If samples are acidified in the field, an additional aliquot should be collected.

2. Add 15 ml of 1N HNO3 per liter of sample in the original container.

3. Hold the sample in the original container for a minimum of 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> before analysis or transfer of the sample.

4. When taking an aliquot for analysis, take acid addition into account. For example:

Sample volume Volume of aliquot to be analyzed reauired 200 ml 203 ml l 400 ml 406 ml 600 ml 609 ml 800 ml 812 ml

1000 ml 1015 ml 2000 ml 2030 ml 3000 ml 3045 ml

-3500 ml 3552 ml

-For other volumes,- adjust aliquots correspondingly, at the rate of 1.5 ml per 100 ml of sample.

Principle of Method Water samples containing suspended matter are filtered through a membrane filter and the filtrate is analyzed. The filtered-water sample is evapor-ated and the residue is transferred to a tared planchet for counting gross

< alpha and/or gross beta activity.

Reagents Lucite: 0.5 mg/ml in acetone Nitric acid, HNO 3: 3N Nitric acid, HNO3 : clincentrated Apparatus Filters;-Millipore, membrane Type AA, 0.8 p Filtration equipment .

Planchets (Standard 2" x 1/8" Beckman planchet)

Proportional counter Procedure

1. Filter a volume of sample containing not more than 100 mg of dissolved solids'for alpha assay, or not more than 200 mg of dissolved solids for beta assay.

Note: For gross alpha and gross beta assay in the same sample limit amount of solids to 100 mg.

2. Wash the non-filterable solids on the filter. (Savethefilters with suspended matter for separate analyses. See Section 2.2.1).

~

3. Evaporate the filtrate to NEAR dryness on a hot plate. Add 25 ml_ concentrated HNO3 and evaporate to NEAR dryness.

Note: For analysis of total residue -(for clear water) proceed as described above but do not fiter the water. Measure out the appropriate amount and proceed with step 3.

Approved by: W /W/ UM//R E.G/ Huebner Section 8.1 8.1 Strontium-89 and Strontium-90 in Milk by Ion Exchange Principle of Method A citrate complex of yttrium, strontium, and barium carriers at the pH of milk is added to the milk sample. The mixture is then passed succes- l sively through cation- and anion-exchange resin columns. Strontium, I barium, and calcium are absorbed on the cation-exchange resin, and the yttrium carrier with. the yttrium 90 daughter of strontium 90 is retained on the anian-exchange resin.

The yttrium is eluted from the anion resin with hydrochloric acid and precipitated as the cxalate. Lanthanum 140, which may be a contaminant, is removed by dissolving yttrium oxalate in concentrated nitric acid and extracting yttrium from the solution into an equal volume of pre-equili-bated tributyl phosphate. The . lanthanum 140 remains in the concentrated nitric acid to be discarded. Yttrium is re-extracted from the organic phase with dilute nitric acid and precipitated as the oxalate. The precipitate is weighed to determine recovery of yttrium carrier, then counted for yttrium 90 activity. {-

Strontium, barium, and calcium are eluted from the cation-exchange resin with sodium chloride solution. Following dilution of the eluate, the alkaline earths are precipitated as carbonates. The carbonates are then converted to nitrates, and strontium and barium nitrate are precipi-t at ed . The nitrate precipitate is dissolved, and barium is precipitated as the chromate, purified as the chloride, and then counted to determine l the carium 140. From the supernate, strontium is precipitated as the nitrate, dissolved in water, and reprecipitated as strontium nitrate.

The nitrate is converted to the carbonate, which is ' filtered, weighed to determine strontium carrier recovery, and counted for " total radio-strontium".

The concentration of strontium-89 is calculated as the difference between the activity for " total radiostrontium" and the activity due to strontium-90.

Apparatus Ion-exchange system: The apparatus for this system is illustrated in Figure 8.1-1. It consists of three glass components connected one above the other for gravity flow. At the top is a graduated, i

1-liter glass separatory funnel which serves as the reservoir.

Below it is connected a 250 ml glass column, 5 cm in diameter and 25 cm long, which services as the cation column. Below this is connected the anion column, a 30-ml glass column, 1.9 cm in dia-meter and 10.5 cm long. Both columns have extra coarse, fritted glass disks at the bottom.

Five milliliters of distilled water are placed in the 30-ml column, and 15 ml Dowex 1 resin are poured into it. The cation column is filled by adding 170 ml Dowex 50W resin in the same way.

L.G/ Huebner Section 8.4 8.4 Strontium 89 and Strontium 90 in Water Samples A. Principle of Method The acidified sample of clear water with stable strontium, barium and calcium carriers is treated with oxalic acid at a pH of 3.0 to precipitate insoluble oxalates. The oxalates are dissolved in nitric acid and strontium nitrate is separated from calcium as a precipitate in 70% nitric acid. The residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides.

After a second strontium nitrate precipitation from 70% nitric acid, the nitrates are dissolved in water and with added yttrium carrier, are stored for ingrowth of yttrium-90. The strontium is again precipitated and separated from 70% nitric acid with the yttrium nitrate being in the supernate. Each fraction is precipitated separately as an oxalate and collected on No. 42 (2.1 cm) Whatman filter or planchet for counting either total radiostrontium or yttrium-90 oV 'both.

E.LG/Ifuebner Section 8.6 8.6 Strontium-89 and Strontium-90 in Milk (Ash), Vegetation, Fish, Wildlife, Soil and Bottom Sediment Samples - Sodium Carbonate Fusion.

Principle of Method Strontium is separated from calcium, other fission products,and other natural radioactive elements. Fuming nitric acid separations remove the calcium and most of the other interfering ions. Radium, lead, and barium are removed with barium chromate. Traces of other fission products are scavenged with yttrium hydroxide. After the Sr-90 and Y-90 equilibrium has teen attained, the Y-90 is precipitated as the hydroxide and con-verted to the oxalate for counting. Strontium is precipitated as the carbonate and counted for tot al activity. Strontium-89 activity is computed as the difference between the total radiostrontium and the strontium-90 (as yttriurt.-90) activity.

1. Weigh out 3 g of ashed sample or silted soil and set aside.

2. Sift into a 250 ml nickel crucible enough Na2003 to very lightly cover the bottom.

3. Add 30 g of Na0H pellets and 5 g of KN03-

4. Add the weighed ash sample and tap the crucible gently to shake ~ the ash down among the pellets.

5. Sift from 10 to 20 grams of Na2CO3 over the ash so it is completely covered.

6. Place in a muffle furnace at 600*C for 20 to 30 minutes to melt and

~

fuse the mixture.

NOTE: If carbon materials remain floating on the surf ace of the melt, cautiously add a few grains of KNO3 and heat for another 5 to 10 minutes.

t Decomposition _ of organic matter is complete when no further reaction is noticed on addition of KN03.

7. Using a long-handled tongs, remove the crucible from the muffle furnace and immediately, but very cautiously, cool in an ice bath until tne melt is completely solidified and cool enough to handle without gloves.

NOTE: It is very important that no moisture come in contact with the melt at this time. One drop of water in the crucible could render the melt very difficult, if not impossible, to remove.

8. Transfer the melt to a 250 ml centrifuge bottle using distilled water and stir until completely dispersed.

NOTE: Rotating the crucible in the palm of one's hand and very gently applying pressure should be sufficient to loosen the melt from the sides of the crucible.

9. Add 2 ml of strontium and 1 ml of barium carriers.

10. Bring to a gentle boil, cool, centrifuge and discard the supernatant.

It is important at this point that evaporation be to com-'

plete dryness. (There should no longer be a smell of acid).

Addition of S ml of HNO3 converts . any metal oxides ' which may have been formed back to nitrates. so they will be dissolved.and not removed with the silicates.

• NOTE: ~ The precipitate consists of calcium, strontium and barium-e^ .- radium nitrates. The supernatant contains ~part of the sample's calcium and phosphate content.

2. Add 30 ml of conc..HNO3 to the precipitate. Heat in a hot -I water bath with stirring for about 10 minutes. Cool the solution 4

in an ice bath with stirring for about 5 minutes. Centrifuge and discard the supernatant.

NOTE: Additional calcium is removed from the sample. Nitrate precipitations with 70% HNO3 will . afford a partial decontamination from soluble calcium while strontium, barium, and radium are completely precipitated.

The separation of calcium is best at 60% HNO 3, however at 60% the precipitation of strontium is not complete.

.Therefore, it- is ~ common practice to precipitate Sr(NO3)2 with - 70% HNO3 which is the concentration of consnercially available 16 _N HNO3 - ,
