r-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 he period t
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 (00CM).
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 Measured concentrations and isotopic composition of noble gases, radioiodine, and particulate radioactivity released to the, atmos-phere during the year, are listed in Table.1.1-1.
A total of 3.81 E+03 curies of noble gases was released with a maximum release 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 curies of alpha emitters was released as airborne particulate matter. Also,1.86 E+01 curies of tritium was released.
- 1. 2 Liquids Released to Lake Michigan A total 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 maximum 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
- t Solid radioactive wastes we're shipped to Richland, Washington; Hanford, Washington; Beatty, Nevada; and/or Barnwell Nuclear Center, South Carolina.
The record of waste shipments is summarized in Table 2.0-1.

- 3. 0 DOSE TO MAN 3.1 Gaseous Effluent Pathways a
Ganna Dose Rates 4
Gamma air and whole body dose rates off-site were calculated based on measured release rates, isotopic composition of the noble gases, 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 occuoancy or shielding f actor of 0.7 included.
The maximum gamma air dose; was 0.15 mrad.

i Beta Air and Skin Rates The ; range of beta particles _ in air is relatively sniall (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. skin tissues is difficult-to calculate because this depends on the beta particle e.nergies, 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 radiotodine, 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 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/m3 or the year.
f Dose to Infant's Thyroid The hypothetical thyroid dcse to an infant living near the plant via ingestion of milk was calculated.
The radionuclide considered was I-131 and the so'urce 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 J
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 c
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 Offsite Oose 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 l
A summar'y of the site meteorological measurements taken during each calendar quarter of the year is given in Appendix II.
The cumula-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.
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 or in the Corporate Offices.
Specific findings for various environmental media are discussed below.

f 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 for reference locations with -indicator locations is included in Table 5.1-1.
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.
5.2 Airborne I-131 and Particulate Radioactivity Concentrations of. airborne I-131 and particulate radioactivity at monitoring locations are summarized 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 th.e 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 sample.
5.3 Aquatic Radioactivity Water samples were collected weekly from six public water works that draw water from Lake Michigan. The samples were composited and emitters and quarterly for tritium.
analyzed monthly for gamma ~
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.
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 gamma 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 Illinois Beach State Park and analyzed for gamma emitters. Gamma radioactivity was below the limit of detection.

i f
- 5. 4 Milk Milk samples were collected monthly from November through April, and weekly the rest of the year..The samples were analyzed for 131 by high-sensitivity methods (iodine chemistry and low level beta counting).
Radiciodine remained be. low the limits of detection of 0.5 ~pCi/l during the grazing period (May - October) and 5.0 pCi/l
.during the non-grazing period (November - April).. The samples were analyzed for gamma emitters beginning in October, 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-producing animals within a five-mile radius of the Zion Generating ~ Station.
The closest dairy animals on record are those at Amestead 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 COMPARISON 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 byf agen-cies 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 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.

Approved by:
C l.F. Huebner 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 De taken to obtain the required sensitivity.
It is recommended that samples 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 are 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 IN_ 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 1

A Approved by: p P "Q/ hgpL t.G. Huebner 2.2.2 Gross Alpha and/or Gross Beta Activity in Dissolved Solids (see note)
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 oeta activity.
Reagents Lucite:
0.5 mg/ml in acetone Nitric acid, HNO :
3N 3
Nitric acid, HNO : concentrated 3
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.
(Save the filters 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 ?s described above but do not fiter the water. Measure out the appropriate amount and proceed with step 3.

E.G/ Huebner Section 8.1 8.1 Strontium-89 and Strontium-90 in Milk by Ion Exchanae 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-sively through cation-and anion-exchange resin columns.
Strontium, 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 anion-exchange resin.
The yttrium is eluted from the anion resin with hydrochloric acid and precipitated as the oxalate.
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-tated.
The nitrate precipitate is dissolved, and barium is precipitated as the chromate, purified as the chloride, and then counted to determine the barium 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 deter mine strontium carrier recovery, and counted for " total radio-stcontium".
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-exchance 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, 1-liter glass separatory funnel which serves as the reservoir.
Below it is connected a 250 mi 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.
I'rinciple 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 l
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 l
nitrate being in the supernate.
Each fraction is precipitated l
separately as an oxalate and collected on No. 42 (2.1 cm) Whatman filter or planchet for counting either total radiostrontium or l
yttrium-90 or both.

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 tons. Radium, ' lead, and b3rium are removed with barium chromate.
Traces of other fission products are scavenged with yttrium hydroxide.
After the Sr-90 and Y-90 equilibrium has been 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 total activity.
Strontium-89 activity is computed as the difference between 'the total radiostrontium and the strontium-90(asyttrium-90) activity.

Sample Preparation - Sodium Carbonate Fusion l
Procedure 1.
Weich out 3 g of ashed sample or silted soil and set aside.
2.
Sift into a 250 ml nickel crucible enough Na2CO3 to very lightly cover the bottom.
3.
Add 30 g of NaOH pellets and 5 g of KNO.
3 4.
Add the weighed ash sample and tap the crucible gently to shake the ash down among the pellets.
5.
Sif t 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 surface of the melt, cautiously add a few grains of KNO3 and heat for another 5 to 10 minutes.
Decomposition of organic matter is complete when no further reaction is noticed on addition of KNO.
3 7.
Using a long-handled tongs, remove the crucible from the muffle furnace and imediately, but very cautiously, cool in an ice bath until the melt is completely solidified and cool enough to handle without gloves.
L 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 7
gently applying pressure should be sufficient to loosen the melt from the sides of the crucible.
9.
Add 2 ml of strontium and I ml of barium carriers.
10.
Bring to a gentle boll, cool, centrifuge and discard the supernatant.

12.
Repeat step (11) three times to put the precipitate in a suitable l
form for further analysis.
13.
Dissolve the pracipitate in 50 ml of concentrated HNO, transfer 3
l to a 250 ml beaker, and take to dryness on a hot plate.
1 NOTE: Evaporation may be done rapidly at first, and then very slowly to prevent spattering.
A jelly-like substance may form at this point, due to hydrated silicic acid formed from the soluble silicates and l
will be removed in the following steps.
l 14.
Bake the remaining residue for at least I hour at 120* to 130' C, cool, moisten the salts with 5 ml of HNO3 and allow to stand at room temperature for 10 minutes.
Then place on a hot plate, bring l
to a boil and add 45 ml of boiling water.
DISPERSE ANY RE.4AINING RESIDUE WITH A GLASS STIRRING R00 AND FILTER IMMEDIATELY into a 250 l
m1 beaker.
Use Whatman No. 541 hardened filter paper.
NOTE: To separate the silicic acid the hydrated acid must be l
changed to a less hydrated and less soluble acid by baking
,t 100* to 130*C.
It is important at this point that evaporation be to com-plete dryness.
(There should no longer be a smell of acid).
Addition of 5 ml of HNO3 converts any metal oxides which may have been formed back to nitrates 50 they will be dissolved and not removed with the silicates.
Filtering must be done immediately as some of the silicates will tend to go back into solution.
Also, due to this fact, removal of silicates by dehydration is not 100% efficient and the process must be repeated at least once and more often if necessary.
15.
Evaporate and repeat step (14) at least once, and again as often as l
necessary.
