INTRODUCTION I
The Dresden Station is located approximately twelve miles south-west of Joliet, Illinois, at the confluence of the Des Plaines and f
Kankakee Rivers where they form the Illinois River. This station uses three boiling water reactor (GE design) to generate electricity.
i Unit 1 began operating in 1960 and has a rated power output of 200 megawatts electrical (MWe). Units 2 and 3 began operating in 1970 and 1971, respectively, each with a rated power output of 800 MWe.
l The General Electr1c Morris Operation Plant (GEMo) is located adjacent to Dresden.
Liquid effluents from Dresden are released to the Illinois River in controlled batches after radioassay of each batch. Gaseous efflu-ents are released to the atmosphere after 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 continu-t ously 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 p'rticulate 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) stations in the vicinity of the Dresden 1
1 i
plant to menura changes in radiation or radioactivity levels that l
may be attributable to plant operation.
If significant changes attributable to'Dresden are measured, these changes are correlated with effluent releases.
External gamma radiation exposure from noble gases and I-131 in milk are the critical pathways at this site; however, a comprehensive environmental monitoring program is conducted which includes many other pathways of less importance.

SUMMARY
Gaseous _and liquid effluents for the period remained below the Technical Specification limits. : Calculations of environmental con-
~ centrations based on effluent, Illinois River flow, and meteorologi-cal 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 0.5 mrem for the year, when:a shielding and occupancy factor _of 0.7 is assumed.
Environmental. monitoring results confirm that deze via o*.her pathways was not significant.

1.0 EFFLUENTS 1.1 CASEOUS EFFLUENTS TO THE ATMOSPHERE
-Measured' concentrations'$bb"isotopiccompositionofnoble gases, radiciodine, and particulate radioactivity released to ttie atmosphere' during Elie year,are i'isted in Table '1.1-1.'
A total of 7.0 E+01 curies $f n'obii gases was released with a maximumreleaserateof3.1Eh02'pC1/sehfromDresden" Unit 1
~
and a total of 3.3~E+04'cubies of noble gases'with a maximum release rate o'f 2.2 E+04 pCi/s'ec wa's' released from Dresden Units 2 and 3.
A total 'f 1.92 curies of I-131"was released'during the o
year.
~
A total of 7.9 curies of beta-gamm'a emitters and non-de-tectable amounts of alpha emitters were' released as airborne i
particulate matter.
1.2 LIQUIDS RELEASED TO ILLINOIS RIVER A total of 5.3 E+06 liters of radioactive liquid wastes containing 0.36 curies (excluding tritium) were discharged from the station. These vastes were released at a maximum monthly average concentration of 3.2 E-09 pCi/ml from Units 2 and 3 which is 3.2% of the Technical Specification release i
limits for unidentified radioactivity. There was no discharge f rom Unit 1.
During the same period, 30.5 curies of tritium and 1.2 E-03 curies of alpha radioactivity were released.
Monthly release estimates and principal radionuclides in liquid effluents are given in Table 1.2-1.

i 2.0 SOLID RADI0 ACTIVE WASTE-l Solid radioactive wastes were shipped to Richland, Washington.
and Barnwell Nuclear Center, South Carolina. The record of waste shipments is summarized in Table 2.0-1.
i 3.0 ' DOSE TO MAN
+
3.1 GASEOUS EFFLUENT PATHWAYS GAMMA DOSE RATES Gamma air and_whole body dose rates off-site were calcu-lated based on measured release rates, isotopic composition of j
J 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 0.5 mrem for the year, with an occupancy or shielding factor of 0.7 included. The maximum gamma air dose was 1.3 mrad.
BETA AIR AND SKIN 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 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 repor t the skin is taken to have a thick-ness of 7.0 mg/cm2 and an occupancy factor of 1.0 is used.
The skin dose from beta and gamma. radiation for the year was 0.6 mrem.
5
The air concentrations of radioactive noblesgases at the off-site receptor locations are_given in Figure 3.1-2..The maximum of f-site beta air dose for the year was 0.1 mrad.
RADIOACTIVE IODINE The human thyroid exhibits a significant capacity to con-centrate ingested or inhaled iodine, and the radiciodine, I-131, released during routine operation of the pl, ant, may be made 4
available to man thus resulting in a dose-to the thyroid. The prinetpal pathway of interest for this radionuclide is ingestion of_radiciodine in milk by an infant. Calculations made in pre-vious years indicate that contributions to doses from inhalation of I-131 and I-133, and I-133 in milk are negligible.
10 DINE-131 CONCENTRATIONS 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 of f-site average concentration is estimated to be 3.6 E-01 pC1/m 3 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 radionuclide considered was I-131 and the source of milk was taken to be the nearest dairy farm with the cows pastured from May to October.
The maximum infant's thyroid dose was 0.1 mrem during the year i
(Table 3.1-1).

4.0 SITE METEORO1EY A'aummary of the site meteorological measurements taken during i
i cach calendar quarter of the year is given in Appendix II.
The data are presented as cumulative joint frequency distributions of 300' l
. level wind direction and wind speed class by atmospheric stability 1
class determined from the temperature difference between the 300' and 35' levels.- Data recovery for these measurements was nearly 100%.
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 pre-vious 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 avail-able for inspection at the Station or in the Corporate Offices.
Specific findings for various environmental media are discussed below.
5.1 GAMMA RADIATION External radiation dose from on-site sources and noble gases released to the atmosphere was measured at eight indicator and nine reference (background)1ocations using solid lithium fluoride
?
thermoluminescent dosimeters (TLD). A comparison of the TLD f
results for reference stations with on-site and off-site indi-l cator stations is included in Table 5.1-1.
An additional 52 TLDs were installed at one mile and site boundary, beginning on 1
8 1
I I
i
e June 1, 1980. Table 5.1-1 lists the results.
5.2-AIRBORNE I-131 and PARTICULATE RADIOACTIVITY Concentrations of airborne.I-131 and particulate radioac-tivity at monitoring locations are summarized in Tables 5.0-2 through 5.0-5.
Locations of the samplers are the same as for j
direct radiation measurements, shown in Figure 5.0-1.
Airborne r
I-131 remained below the LLD of 0.10 pCi/m throughout the year, j
3 Gross beta concentrations ranged from 0.01 to 0.22 for the indicator. stations with an average concentration of 0.05 for the-l year..No radioactivity attributable to station operation was
/
detected in any sample.
1 5.3 AQUATIC RADIOACTIVITY
--Cooling water samples were collected daily and composited for analysis weekly for the Unit 1 Inlet canal and Units 1 and 2/3 Discharge Canals. Analytical results did not indicate any i
measurable radioactivity attributable to plant operation, except in two samples collected on April 4 and 11 at the discharge canal D-19-1.
The gross beta concentration in these two samples was 148 and 440 pCi/1.
Gamma isotopic and Strontium 89/90 analyses were performed as supplementary analyses. The results indicated the presence of cobalt-60 to account for the high activity measured which is attributable to plant operations.
Surface water samples were collected weekly from the Illinois River at the EJ and E Railroad Bridge and composited monthly to analyze for gamma emitters. The gamma emitters were below the detection limit of 10 pC1/1 in all samples collected during the 1
9
year.:
Well water. samples were collected monthly beginning October 1980 and analyzed for tritium. The levels of tritium were generally in the range to b3 expected of this nuclide in this medium in the envi-ronment and were not attributable to station operation.
5.4 MILK Milk samples were co11ccred weekly during the grazing season and monthly during the balance of the year from four farms; the Davidson Farm located'six miles northeast of Dresden Station, the Corbin Farm located about 10 miles south, the Mather Farm (background location) located about 16 miles northeast, and the Yunker Farm, five miles t
north-northwest, which replaced Davidson in May 1980 after Mr. David-son sold his cows.
1-131 was determined for each sample by a gamma spectrometry or chemical separation of I" and beta counting.
I-131 remained below the detection limits of 0.5 pC1/1 during the grazing period (May to October) and 5.0 pCi/1 during the non-grazing period (November to April).
5.5 SPECIAL COLLECTIONS Service water contaminated by leaks in the LPCI heat exchang-er was released into the cooling lake early in the year. 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 l
and gamma activities have not indicated the presence of detect-able concentrations of radioactivity due to the station. Data are listed on page 12.
