4 INTRODUCTION The Dresden Station is located approximately twelve miles southwest of Joliet, Illinois, at the confluence of the Des Plaines and Kankakee Rivers where they form the Illinois River.

This station uses three boiling water reactors (GE design) to generate electricity.

Unit 1 began operating in 1960 and has a rated power output of 200 megawatts electrical (MWe).

It has been decom-missioned as of August 31, 1984.

Units ' and 3 began operating in 1970 and 1971, respectively, each with a rated pt -

output of 800 MMe.

The General Electric Morris Operation Plant (GEMo) is Cated adjacent to Uresden.

Liquid effluents from Dresden are released to the Illinois River in controlled batches after radioassay of each batch.

Gaseous effluents are released to the atmosphere af ter delay to permit decay of short half-life gases.

Releases to the atmosphere are calculated on the basis of analyses of daily grab samples of noble gases and continuously collected composite samples of iodine and particulate matter.

The results of effluent analyses are summarized on a monthly basis and reported semiannually to the Nuclear Regulatory Commission as required per Technical Specifications.

Airborne concentrations of noble gases, I-131 and particulate radioactivity in off-site areas are calculated using effluent and meteorological data and data on isotopic composition of effluents.

Environmental monitoring is conducted by sampling at indicator and reference (background) locations in the vicinity of the Dresden plant to measure changes in radiation or radioactivity levels that may be attributable to plant oper-ation.

If significant changes attributable to Dresden are measured, these changes are correlated with effluent releases.

External gamma radiaton exposure from noble gases and I-131 in milk are the critical pathways at this site; however, a comprehensive environmental monitoring program is conducted which includes many other pathways of less importance.

SUMMARY

Gasecus and. liquid effluents for' the period remained below the Technical l

Specification ~ limits.

Calculations of environmental concentrations based on effluent,. Illinois River flow, and meterological data for the period indicate l

that consumption by the~ public of - radioactive materials attributable to the plant are unlikely to exceed regulatory limits.

Radiation exposure from radio-nuclides released to the atmosphere ' represented the critical pathway for the period with a maximum individual dose estimated to be 0.0022 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 Off-Site 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 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 non-detectable amount of noble gases was released from Dresden Unit I and a total of 1.68E+02 curies of noble gases with a maximum release rate of 6.36 pC1/sec was released from Dresden Units 2 and 3.

A total of 1.86E-01 curies of I-131 was released during the year.

A total of 4.93E-02 curies of beta-gamma emitters and 2.20E-10 curies of alpha emitters were released as airborne particulate matter with a maximum release rate of 3.83E-03 pCi/sec.

Also, 25.93 curies of tritium was released.

1.2 Liquids Released to Illinois River A total of 3.02E+07 liters of radioactive liquid wastes containing 0.26 curies (excluding tritium) were discharged from the station.

These wastes were released at a maximum quarterly average concentra-tion of 1.97E-06 pC1/ml from Units 2 and 3 which is 0.01% of the Technical Specification release limits for unidentified radio-activity.

However, this concentration is prior to dilution in the cooling pond and release to unrestricted area.

This added dilution is approximately a factor of ten thousand.

There was no discharge from Unit 1.

During the same period, 21.93 curies of tritium and undetectable quantity of alpha radioactivity were released.

Quarter-ly release estimates and principal radionuclides in liquid effluents are given in Table 1.2-1.

2.0 SOLID RADI0 ACTIVE WASTE Solid radioactive wastes were shipped to Chem-Nuclear, Chanahon, Illinois and Barnwell, South Carolina; Richland, Washington; Barnwell Nuclear Center, South Carolina; SEG and Quadrex, Tennessee; Westinghouse-DRR, Pennsylvania; and Alaron, Pennsylvania.

The record of waste shipments is summarized in Table 2.0-1.

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways Gamma Dose Rates Gamma air ana wheh hody dose rates off-site were calculated based on measured release rates, isotopic composition of the noble gases, and meteorological data for the period (Tabl e 3.1-I).

Isodose 3

~

conteurs of whole. body dose ' are shown lin Figure 3.1-1 for the year.-

Based on measured effluents. and - meteorological data, the maximum

-dose to an individual would be 0.0022 mrem for the year, with ' an occupancy-or shielding factor of 0.7 included.

The maximum gamma L

air dose was 0.0049 mrad.

1 Beta Air and Skin Rates T;,e range or 00t3 rFticles 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 skin tissues is difficult to' calculate because this depends-on the beta particle energies, thickrass of inert skin, and clothing.

covering sensitive tissues.

For purposo taken to have 'a thickness of 7.0 mg/ cmc,s of this report the skin is and an occupancy factor. of 1.0 is used.

The skin dose from beta and gamma radiation for the year was 0.010 mrem.

-The air concentrations of radioactive nobla 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 0.0087 mrad.

Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine, and the radioiodine, 1-131, 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 radionuclides is ingestion of radioiodine in milk by an infant.

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 Concentrations in Air The calculated concentration contours for I-131 in air are shown in i

Figure 3.1-3.

Included in these calculations is an iodine cloud depletion f actor which accounts for the phenomenon of elemental iodine deposition on the ground.

The maximum off-site average concentration is estimated to be 3.91E-03 pCi/m3 for the year.

Dose to Infants Thyroid The hypothetical thyroid dose to an infant living near the plant via ingestion of milk was calculated.

The radionuclides considered was 1-131 and the source of milk was taken to be the nearest dairy f arm with the cows pastured from tiay to October.

The maximum infants's thyroid dose was 0.073 mrem during the year (Table 3.1-1).

Concentrations of Particulate in Air

' Concentration contours of radioactive airborne particulate are.shown in - Figure 3.1-4.

The maximum off-site average level is estimated to be 4.63E-04 pC1/m3,.

l Summary of Doses Table 3.1-1 summarizes the doses resulting from releases of airoorne radioactivity via the different' exposure pathways.

l 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 shore-line.

Not all of these pathways are applicable at a given time or station but a reasonable approximation of the dose can be made by ad-justing 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, boca, and skin; specific parameters for use in-the equations are gven in the Commonwealth Edison Off-site Dose Calculation fianual.

The maximum whole body dose for the year was 0.00063 mrem and no organ dose exceeded 0.00093 mrem.

4.0 SITE f1ETEOROLOGY A summary of the site meteorological measurements taken during each calendar quarter of the year is given in Appendix II.

Ele data are presented as cumulative joint frequency distributions of 300' level wind direction and wind speed class by atmospheric stability class determined from the temperature difference between the ~ 300' and 35' l evel s.

Data recovery for all measurements on the tower was 98.4%.

5.0 ENVIRONf1 ENTAL f10flITORING Table 5.0-1 provides an outline of the radiological environmental moni-toring program as required in current Technical Specifications. This program went into effect in December 1977 and differs from previous programs in the number and types of analyses performed.

Tables 5.0-3 to 5.0-6 summarize data for the year.

Except for tabl es 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 Office.

Specific findings for various environmental media are discussed bel ow.

5.1 Gamma Radiation External radiation dose from on-site sources and noute gases released to the atmosphere was measured at eight indicator and nine reference (background) locations using CaSO :Dy thermoluminescent dosimeters 4

(TLDs).

A comparison of the TLD results for reference stations with on-site and off-site indicator stations is included in Table 5.1-1.

An additional 52 TLDs were installed at both five miles and the site boundary, beginning on June 1,1980.

Table 5.1-1 lists the results.

4 5.2 Airborne I-131 and Particulate Radioactivity Concentrations of ai rborne I-131 and particulate radioactivity at monitoring locations are summarized in Tables 5.0-3 through 5.0-6.

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

Airborne I-131 remained below the LLD of 0.10 pC1/m3 throughout the year.

]

Gross beta concentrations ranged from 0.004 to 0.059 pC1/m3 and averaged 0.027 pCi/m3, No radioactivity attributable to plant operation was detected in any sample.

5.3 Aquatic Radioactivity Cooling water samples were collected daily and composited for analysis weekly from the Unit 1 Inlet Canal and Units 1 and 2/3 Discharge Canals.

Analytical results did not indicate any measurable radioactivity attributable to plant operation.

Surface water samples were collected weekly from the Illinois River at the EJ a E Railroad Bridge and composited monthly to analyze for gamma emitters.

Cs-134 and Cs-137 levels were below the detection limit of 10 pCi/1 and all other gamma emitters were below the detection limit of 20 pCi/l in all samples collected during the year.

Well water samples were collected quarterly beginning October 1980 and analyzed for gross alpha, gross beta, and tritium.

The levels of activity detected were generally in the range to be expected in this medium in the environment and were not attributable to station operation.

Levels of gamma radioactivity in fish samples were measured and found in all cases to be below the lower limits of detection of 0.1 pCi/g wet weight for the program.

A sediment sample was analyzed by gamma spectroscopy.

Gamma-emitters were below the limits of detection indicating the presence of no radioactivity due to station operation.

5.4 Milk Milk samples were collected weekly during the grazing season and

~

monthly during the balance of the year from two farms:

the Biros Farm (background location), located about 11.5 miles southwest; and the Trotter Farm, located about 6.1 miles south.

1-131 was deter-mined for each sample by chemical separation of I and beta counting.

1-131 remained below the detection limits of 5.0 pC1/1 during. the non-grazing period (November to April) and 0.5 pC1/1 during the grazing period (May to October).

5.5 Special Collections Service water contaminated by leaks in the LPCI heat exchanger was released into the cooling lake early in 1978.

To monitor effects-on the concentrations of radioactivity in the cooling canal a program was begun in October 1978 of collecting weekly grab samples of water at the Dresden Road and County Line Road crossings of the canal.

Concentrations of both gross beta and gamma activities have not indicated the presence of detectable concentrations of radio-activity due to the station.

Data are listed on Page 34.

5.6 Missed Samples Listing of missed samples collections are presented in Appendix III.

6.0 ANALYTICAL PROCEDURES A summary of the procedures used for analyzing radioactivity in environ-mental samples is given in Appendix V.

7.0 MILCH ANIMAL CENSUS A census of milch animals was conducted within a five mile radius of. the station.

The survey was conducted by " door-to-door" canvas by A. Lewis on August 19 and 26, 1988.

There are no dairy farms within a five mile radius of the Dresden Nuclear Power Station.

I 8.0 DEAREST RESIDENT CENSUS The nearest resident census was conducted on August 26, 1988.

There were no changes since the previous census.

Results of milch animal and nearest resident census are presented in Appendix IV.

9.0 IflTERLABORATORY C0fiPARIS0fl PROGRAfi RESULTS Teledyne Isotopes fiidwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interl aboratory 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 concentrations of radio-nuclides known to the issuing agency but not to participant laboratories.

The purpose of such a program is to provide an independent check on the l ab o r a to ry '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.

The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water, air filters, and food samples during the period flay 1984 through flovember 1988.

This program has been conducted by the U.

S.

Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental flonitoring and Support Laboratory, Las Vegas, flevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLDs) durint the period 1976, 1977, 1979, 1980, 1984, and 1985-1986 through participation in the Second, T hi rd, Fou rth, Fifth, Seventh and Eighth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.

Table A-3 lists results of the analyses on in-house spiked samples.

Table A-4 lists results of the analyses on in-house " blank" samples.

Attachment B lists acceptance criteria for " spiked" samples.

Addendum to Appendix A provides explanation for out of limit results.

ADDENDUM TO APPENDIX A The following is an explanation of the reasons why certain samples were outside the control limit specified by the Environmental Protection Agency for the Interlabora-tory Comparison Program starting January 1987.

EPA Lab Code Analysis TIf1L Result Control Limit Explanation STil-504 Sr-89 57.024.3 60.3-77.7 fiilk had high fat content which Sr-90 32.0 1.0 32.4-37.6 made analyses difficult.

Ad-dition of errors to TIhL result would put values wi thin EPA control limits.

EPA slso had the saae problem in analyzing its own sample.

STW-511 Ra-228 8.121.4 4.6-8.0 TIf1L results are usually within EPA control limits.

Analysis of the next sample was within EPA control limits.

No further action is planned.

STW-516 Cr-51 80.3217.5 61.3-78.7 Results in the past have been within EPA control limits and TIf1L will monitor the situation in the future.

ST F-524 K

1010.72158.5 1123.5-1336.5 Error in transferrance of data.

Correct data was 1105233.

Results in the past have been within the limits and TIf!L will monitor the situation in the future.

STW-532 I-131 9.0 2.0 6.2-8.8 Sample recounted after 12 days.

The average result was 8.821.7 (within EPA control limits).

The sample was recounted in order to check the decay.

Results in the past have been within the limits and TINL will continue to monitor the situ-ation in the future.

STW-534 Co-60 63.3 1.3 41.3-58.7 High level of Co-60 was due to

{

c on t ani n a t i o n of beaker.

Beaker was discarded upon dis-c ove ry of contamination and sample was recounted.

Recount results were 53.223.6 and 50.9 2.4 l

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 samples be' preserved at the time of collection by adding enough IN HNO3 to the sample to bring it to pH 2 (15 ml IN HNO per liter of saaple is usually sufficient).

If samples J are to be col 3-lected 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 0.00444 hours 2.645503e-5 weeks 6.088e-6 months 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.

1 TIML-W-01 Revision 0, 11-22-85 DETERMINATION OF SROSS ALPHA AND/0R GROSS 8 ETA IN WATER (Dissolved Solids or Total Residue )

a Principle of Method l

Water samples containing suspended matter are filtered through a membrane filter and the filtrate is analyzed.

The filtered water sample is evaporated and the residue is transferred to a tared planchet for counting gross alpha and gross beta activity.

Reagents All chemicals should be of " reagent-grade" or equivalent whenever they are conenercially avilable.

Lucite:

0.5 mg/ml in acetone Nitric acid, HNO : 16 N (concentrated), 3 N (187 al of 16 N HNO3 3

diluted to 1 liter)7 1 N_ (62 ml of 16 N_l NO3 diluted to 1 liter).

Apparatus Filter, Millipore, membrane Type AA, 0.08 Filtration equipment Planchets (Standard 2" x 1/8" ringed planchet)

Proportional counter Electric hot plate Drying oven Muffle furnace Procedure 1.

Filter a volume of sample containing not more than 100 mg of

'i dissolved solids for aplha assay, or nnt more than 200 mg of dissolved solids for beta assay.

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

2.

Wash the non-filterable solids on the filter with DI water.

(Save the filters with suspended matter for separate analysis.

See Proc.

No. TIML-W-02.)

3.

Evaporate the filtrate to NEAR dryness on a hot plate.

a For analysis of total residue (for clear w=+er), proceed as described l

above but do not filter the water.

Measure out the appropriate amount and proceed with Step 3.

W-01-02

_________-___________-_a

TIML-W-01 R; vision 0, 11-22-85 4.

Add 25 al of concentrated HNO3 and evaporate to NEAR dryness again.

Note:

If water sagles are known or suspected to contain chloride salts, these chloride salts sh'uld be converted to nitrate o

salts before the sample residue is transferred to a stainless steel planchet. (Chlorides will attack stainless steel.and increase the the sag le solids.

No correction can be made for these added solids.) Chloride salts can be converted to nitrate salts by adding concentrated HNO3 and evaporating to near dryness.

l S.

With D.I. water and a few drops of 3 N HNO, transfer the residue to 3

a 50 ml beaker using a rubber policeman to wash the walls.

Evaporate to NEAR dryness.

6.

Transfer quantitatively the residue to a TARED PLANCHET, using an unused plastic disposable pipette for each sagle, (not more than 1 inl at a time) evaporating each portion to dryness under the lamp.

Spread residue uniformly on the planchet.

Note:

Non-uniformity of the sagle residue in the counting planchet interferes with the accuracy and precision of the method.

7.

Wash the beaker with a minimum amount of 1 N HNO3 several times and combine the washings and the residue in the planchet, using the rubber policeman to wash the walls.

Evaporate to dryness.

Note: Rinse the rubber policeman with D.I. water between samples.

f 8.

Bake in muffle furnace at 450* C for 45 minutes, cool and weigh.

9.

Add a few drops (6-7) of the lucite solution and dry under the infa-red lamp for 10-20 minutes.

10.

Store the sagle in a dessicator until ready to count because vapors from the moist residue can damage the detector and the window and can cause erratic measurements.

11.

Count the gross alpha and/or the gross beta activity in a low back-ground proportional counter.

Note:

If the gas-flow internal proportional counter does not discrimi-nate for the higher energy alpha pulses at the beta plateau, the activity must be subtracted from the beta plus alpha activity.

This is particularly important for samples with high alpha activity.

Samples may be counted for beta activity immediately af ter baking; l

alpha counting should be delayed at least 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months (until equilibrium l

has occured).

5.

Dispense 13 al of sample into marked vials and " dead" water into vials marked Bkg-1,2, and 3.

Note 1: Pipetter is set (and calibrated) to deliver 6.5 m1, so pipette twice into each vial.

Use new tip for each sample and new tip (one) for three background samples.

Note 2: Make sure the pipetter has not been reset.

if it has been reset, or if you are not sure, do not use it; check with your supervisor.

Note 3: Make sure the plastic tip is pushed all the way on to the pipetter and is tight.

If it is not, the air will be drawn s

in and the volume withdrawn will not be correct (it will be smaller).

6.

Dispense 13 ml (see Notes 1,2, and 3, above) of " dead" water into each vial marked "St-1", "St-2", and "St-3."

7.

Take a 0.1 ml (100A ) pipetter and withdraw 0.1 ml of water from each of the three standard vials.

Discard this 0 1 m1 of water.

8.

Take a new 0.1 ml tip.

Dispense 0.1 ml of standard into each of the three vials marked "St-1", "St-2", and "St-3."

9.

Take all-vials containing samples, background, and standard to the counting room.

Note:

To avoid spurious counts, scintillator should'not be added under flourescent light.

10.

Dispense 10 ml of Insta-Gel into each vial (one at a time), cap J

tightly, and shake VIG0ROUSLY for at least 0.5 minutes.

Recheck the cap for tightness.

Let the vials dark-and temperature-adapt for about one hour.

Note 1:

To check if vials reached counter temperature, inspect one vial (Bkg).

The liquid should be transparent.

If the temperature is too high (or too low), the liquid will be white and very viscous.

Note 2:

The temperature inside the counter should be between 10*

and 14* C (check thermometer).

In this temperature range, the liquid is transparent.

14.

Set the counter for 10c rin counting time and infinite cycles.

(Follow manufacturer's procedure for setting the counter.)

15.

Fill out the loading sheet, being sure to "dicate the date and time counting started, and your initials.

Note:

Do not count prepared background and standard sets with another batch of samples if plastic vials are used.

Prepare new backgrounds and standards for each batch.

If glass vials are used, the prepared background and standard sets can be counted with other batcher up to one (1) month after preparation provided they are not taken out of the counter (not warmed up) and the same vial type from the same manufacturing batch (the same carton) is used.

After one month prepare new sets of backgrounds and standards.

l 1-131-01 Revisisn 0, 06-12-85 Determination of I-131 in Milk by Ion Exchange (BatchMethod)

Principle of Method After samples have been treated to convert all iodine in the unple to a common oxidation state, the iodine is isolated by solvent extraction or a combination of ion exchange and solvent extraction steps.

Iodine, as the iodide, is concentrated by adsorption on an anion resin.

Following a Nacl wash, the iodine is eluted with sodium hypochlorite.

Iodine in the iodate form is reduced to 12 and the elemental iodine extracted into CCl, back-extracted into water then finally precipitated as palladium 4

iodide.

Chemical recovery of the added carrier is determined gravimetrically from the PdI2 precipitate.

1-131 is determined by beta counting the PdI -
