INTRODUCTION

= The Dresden StatL.. is located approximately twelve miles southwest of Joliet, Illinois at the confluence of the Des Plaines and Kankakee Rivers where thev form the Illinois River. This

l station uses two boiling water reactors (G.E. design) to generate blectricity.' Unit 1, which began '

-1

' operating in 1960 and had a rated power output of 200 megawatts electrical (MWe), was shut -

' down on August 31,1984 and is currently being decommissioned. Liquid radwaste from Unit 1 is transferred to Units 2 and 3 for collective processing and discharge. Units 2 and 3 began j

operating in 1970 and 1971, respectively, each with a net rated power output of 809 MWe.

1 Lic uid effluents from Dresden n released'to the Illinois River in controlled batches after racioassay of each batch. Gaseous effluents are released to the atmosphere after delay to-permit decay of short-lived (noble) gases. Releases to the atmosphere are calculated on the basis of analyses of weekly grab samples of noble gases as well as continuously collected composite

. samples of iodine and particulate activity 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 mer Technical Specifications. Airborne concentrations of noble gases, I-131, and particulate rac ioactivity in offsite areas are calculated using isotopic composition of.

? control effluent and meteorological data.

Environmental monitoring is conducted by sampling at indicator and control (background) i

- N locations in the vicinity of the Dresden Station to measure changes in radiation or radioactivity

)

V-levels that may be attributable to station operation. If significant changes attributable' to -

d Dresden are measured, these changes are correlated with efflu~ nt releases. External gamma -

e radiation ~ exposure from. noble gases and internal dose from I-131 in milk are the critical 1

. pathways at this site; however, a comprehensive environmental monitoring program is

. conducted which includes many other p.,thways which are less significant in terms of radiation 1

protection.

SUMMARY

l Gaseous and liquid effluents for the period remained below the Dresden Station Offsite Dose Calculation Manual (ODCM) limits. Calculations of environmental concentrations based on effluent, Illinois River flow, and meteorological data for the period indicate that consumption

. by the public of radioactive materials attributable'to the Dresden Station does not exceed regulatory limits. Radiation exposure from radionuclides released to the atmosphere 3

represented the critical pathway for the period with a maximum adult dose estimated to be 7.30E-03 mrem for the year, where a shielding and occupancy factor of 0.7 is assumed. The tissessment of radiation doses is performed in accordance with the ODCM. The results of these inalyses confirm that the station is operating in compliance with 10CFR50 l

10CFR20 and 40CFR190.

1.0 EFFLUENTS V

f 1.1 Gaseous Effluents to the Atmosohere Measured concentrations and isotopic composition of noble gases, radiciodine, and particulate radioactivity released to the atmosphere during the year are listed in Table

.1.1-1. A total of 2.43E+02 curies of noble gases with a maximum quarterly average t

release rate of 1.19E+01 pCi/sec was released from Dresden Units 1,2 and 3.

A total of 5.86E-03 curies of I-131 was released during the year with a maximum quarterly average release rate of 3.94E-04 Ci/sec.

4 A total of 7.97E-03 curies of beta gamma emitters was released as airborne particulate -

j i

matter with a maximum quarterly average release rate of 4.03E-04 Ci/sec. Alpha emitting radionuclides totaled 3.92E-06 curies. Also,5.96E+00 curies of tritium'were

{

released with a maximum quarterly average release rcte of 2.94E-01 pCi/sec.

i 1.2 Liquids Released to Illinois River A total of 6.61E+06 liters of radioactive liquid wastes containing 1.41E-02 curies of h

fission and activation products (excluding tritium, noble gases and gross alpha) was discharged from the station. These wastes were released at a maximum quarterly N

average diluted concentration of 2.36E-08 pCi/ml from all units. During the same period,1.25E+01 curies of tritium were released with a maximum quarterly average y

diluted concentration of 1.64E-05 Ci/ml. Alpha emitting radionuclides were below detectable levels. Quarterly release values are given in Table 1.2-1.

' 2.01 SOLID RADIOACTIVE WASTE u

Solid radioactive wastes were shipped to CNSI, Barnwell, South Carolina; AERC, Oak Ridge, Tennessee; SEG, Oak Ridge, Tennessee and Hake, Memphis Tennessee. The record of waste shipments is summarized in Table 2.0-1.

[

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways A review of the Dresden REMP air sampler stations was performed by the meteorlogical firm of Murray & Trettel in the fourth quarter of 1997. Four benchmarks were adopted to evaluate the suitability of the air sampler locations.

These were:

1. The air intake should be located between two (2) and fifteen (15) meters above the ground.

2. The separation distance between air sampler inlets and walls, parapets, penthouses, etc. must be at least two (2) meters.

i;

3. Inlets should be at least twenty (20) meters from tree drip lines (defined as "an imaginary line that is formed around a tree, extending down from the n

outermost V

. below"). parts of the branches, ~where moisture could fall to the ground 3

l (3

4. The distance between the sampler and obstructions should be at leas r )

times the height that the obstruction protrudes above the sampler.

Air sampler sites D-3,45,8,11 and 12 comply with all four benchmarks. All othe1 samplers failed to meet one or more of the benchmarks. Sites failing to meet o more of the benchmarks may tend to under-represent air concentrations under c conditions such as in summer when trees are in leaf. Dresden Station reviewing the Murray & Trettel report to assess proper actions to rectify the deficiencies.

Table 3.1-1 summarizes the doses resulting from releases of airborne rad the different exposure pathways.

3.1.1 Noble Cases 3.1.1.1 Gamma Dose Rates a

Offsite gamma air and total body doses are shown in Table 3.1-1 and were calculated based on measured release rates, isotopic composition of the noble gases, and average meteorological data for the period.

Isodose contours based on concurrent meteorological data for gamma dose are shown in Figure 3.1-1.

Based on measured effluents and meteorological data, the maximum dose to an adult would be 7.30E-03 mrem for the year, with an occupancy or shielding factor of 0.7 included, and based on measured effluents and concurrent (q

meterological data would be 8.16E-03 mrem (Table 3.4-1).

"f maximum gamma air dose was 6.23E-03 mrad and 9.33E-03 mrad based The on concurrent meterological data (Table 3.4-1).

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 l'

few meters or less); consequently, plumes of gaseous effluents may be considered " infinite" for the purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive i

skin tissues is difficult to calculate due to the effect of the beta particle i

energies, thickness of inert skin, and clothing covering sensitive tissues.

For put 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 5.14E-03 mrem (Table 3.1-1).

The air concentrations of radioactive noble gases at the offsite receptor locations are given in Figure 3.1-2. The maximum offsite beta air dose for the year was 3.81E-04 mrad (Table 3.1-1).

3.1.2 Radioactive Iodine The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. The radioiodine,I-131, released during routine operation of the station, may be made available to man resulting in a dose to the thyroid. The principal pathway of interest for this radionuclide is ingestion of radioiodine in i

milk by an infant.

distributions of the wind direction for the 300'. level and wind speed class by atmospheric stability class deterndned from the temperature difference between the 300' and 35' levels.

- Data recovery for all measurements on the tower was 99.6% during 1997 (Table 3.4-1).

j 5.0 ENVIRONMENTAL MONITORING Table 5.0-1 and Table 5.0-2 provide an outline of the Radiological Environmental i

Monitoring Program (REMP) as required in the ODCM. Tables 5.0-3 to 5.0-6 summarize i

data for the year.

Except for tables of special interest, tabulated results of these analyses are no longer includt d 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 below.

5.1 Gamma Radiation

.I

.. External radiation dose from onsite sources and noble gases released to the atmosphere was measured using CaSO :Tm thermoluminescent dosimeters (TLDs).

j 4

.TLD results are listed in Table 5.1-1 and locations are shown in Figures 5.0-1 and 5.0-2.

Quarterly external radiation dose at seventeen air sampling locations averaged 15.7 mR and was similar to that measured in 1985 (13.5 mR),1986 (14.4 mR),1987 (15.8 mR),1988 (14.9 mR),1989 (15.7 mR),1990 (14.9 mR),1991 (14.0 mR),1992 (15.6 mR),

1993 (15.5 mR),1994 (14.7 mR),1995 (14.1 mR) and 1996 (13.0 mR). The differences are not statistically significant.

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 interlaboratory comparison program to 6

9.59E-04 Ci A.1 In June,1994, elevated tritium levels were discovered in the on-site storm sewers. The highest storm drain concentration, 1.1IE+03 pCi/l, from the 3rd quarter was used for both the 1st and 2nd half of 1997. The total activity released is based on an estimated typical discharge flow of 10 gallons per minute. An estimated 1.09E-03 Ci of H-3 may have been released into the environment. Various storm sewer locations on-site are now periodically analyzed for tritium.

W 2.1 On March 18,1997 it was discovered that the Unit 3 Main Turbine had a gland seal leak which was allowing steam to C

enter the II3 Turbine Oil Reservoir. There is an exhaust fan on the reservoir which exhaust directly into the environment with no monitoring. It is unknown when the leak started. The leak stopped on March 27,1997 when the Unit was shutdown for a refuel outage. The gland seal was repaired. The following activity is estimated to have been released to the environment:

Co-60 4.85E +02 Ci Mn-54 5.50E+01 pCi Xe-135 9.40E+01 Ci Xe-135m 3.07E+02 pCi B.2

'the East Turbine Building Ventilation System was found to have a contaminated fan blade in 1996. This system is designed to pull air in from outdoors and ventilate non-Radiologically Posted Areas and then exhaust the air back into the environment. It is unknown when the fan blade become contaminated. Smears of the ductwork indicate the presence of Co-60, Ba-133 and Cs-137. An estimated 8.00E+00 pCi of Co-60,3.00E+00 Ci of Ba-133 and 5.00E+00 pCi of Cs-137 may have been exhausted into the environment for all of 1997.

B.3 The heating steam system has low level contamination present. During operation of the system, some steam is ventel directly into the environment, Isotopic analysis of the condensate in the system indicate the presence of Co-60, Mn-54 and Cs-137.- An estimated 2.'X)E-01 Ci of Co-60,1.60E+00 Ci of Mn-54 and 2.50E-01 pCi of Cs-137 may have been exhausted into the environment for all of 1997.

1.38E-02 Ci A.1 In June,1994, elevated tritium levels were discovered in the on-site storm sewers. The highest storm drain concentration, 1.11E+03 pCi/1, from th: 3rd quarter was used for both the 1st and 2nd half of 1957. The total activity released is based on an estimated typical discharge flo-: of 10 gallons per minute. An estimated 1.1103 Ci of H-3 may have been released into the environment, Various storm sewer locations on-site are now periodically analyzed for tritium.

O yll On September 4,1997 it was discovered that the gland seal on the Unit 3 Main Turbine which had been repaired during the previous refuel outage was leaking again allowing steam to enter the U3 Turbine Oil Reservoir. There is an exhaust fan on the reservoir which exhaust directly into the environment with no monitoring. It is unknown when the leak resumed. The leak continued through the end of 1997 into 1998. The following activity is estimated to have been released to the environment:

Kr-87 5.15E+02 pCi Xe-138 1.20E+04 pCi B.2 The East Turbine Building Ventilation System was found to have a contaminated fan blade in 1996. This system is designed to pull air in from outdoors and ventilate non-Radiologically Posted Areas and then exhaust the air back into the environment, it is unknown when the fan blade become contaminated. Smears of the ductwork indicate the presence of Co-60, Ba-133 and Cs-137. An estimated 8.00E+00 pCi of Co-60,3.00E+00 pCi of Ba-133 and 5.00E+00 pCi of Cs-137 may have been exhausted into the environment for all of 1997. This release was attributed as an abnormal release in the first half of 1997 and the pCi values are not included in the 1997 s cond half totals.

B.3 The heating steam system has low level contamiration present. During operation of the system, some steam is vented directly into the environment. Isotopic analysis of the condensate in the system indicate the presence of Co-60, Mn-54 and Cs-137. An estimated 2.00E-01 pCi of Co-60,1.60E+00 Ci of Mn-54 and 2.50E-01 pCi of Cs-137 may have been exhausted into the environment for all of 1997. This release was attributed as an abnormal release in the first half of 1997 and the pCi values are not included in the 1997 second half totals.

These releases are not included in the Effluents Summation of all Releases Tables but are included in the Radiological Impact on Man.

Appendix V I

Interlaboratory Comparison Program 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 concentrations of radionuclides know 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 concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the Laown values to the participant laboratories and specifies controllimits. 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 rese!ts in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water, air filters, and food samples during the current year. This program is conducted by O

the U.S. Environmental Protection Agency Office of Research and Developement National Exposure (V

Research Laboratory Characterization Research Division-Las Vegas, Nevada.

Table A-2 lists results of the analyses on in-house " spiked" samples.

Table A-3 lists results of the in-house " blank" samples.

Table A-4 lists results of the in-house " duplicate" program.

Table A-5 list results of the Environmental Measurement Laboratory Quality Assessment Program.
