JNTRODUCTION l LaSalle County Station, a two-unit BWR station is located near Marseilles, Illinois in LaSalle B County,3.5 miles south of the Illinois River. Each reactor is designed to have a capacity of 1078 MW net. Unit No. I loaded fuel in March 1982. Unit No. 2 loaded fuel in late December 1983.

The station has been designed to keep releases to the environment at levels below those specified in the regulations.

Liquid effluents from LaSalle County Station are released to the Illinois River in controlled batches after radioassay of each batch. Gaseous effluents are released to the atmosphere after I delay to permit decay of short-lived (noble) gases. Releases to the atmosphere are calculated on the basis of analyses of routine grab samples of noble gases as well as continuously collected l composite samples of iodine and particulate radioactivity sampled during the course of the l year. The results of effluent analyses are summarized on a monthly basis and reported to the Nuclear Regulatory Commission as required per Technical Specifications / Standards. Airborne concentrations of noble gases, I-131, and particulate radioactivity in offsite areas are calculated using effluent and meteorological data.

Environmental monitoring is conducted by sampling at indicator and control (background) l locations in the vicinity of the LaSalle County Siation to measure changes in radiation or I radioactivity levels that may be attributable to statien operations. If significant changes attributable to LaSalle County Station are measured, these changes are correlated with effluent I releases. External gamma radiation exposure from noble gases and internal dose from I-131 in l milk are the most critical pathways at this site; however, an environmental monitoring program is conducted which includes these and many other pathways which are less significant in terms of radiation protection.

p Comed is in the process of implementing a Uniform Radiological Environmental Monitoring Program, referred to as UREMP, among the Comed nuclear stations. This program includes l generic requirements pertaining to environmental sampling and analysis, an annual land use I census, an interlaboratory comparison program and environmental reports. LaSalle County Station implemented UREMP in October of 1995.

SUMMARY

Gaseous and liquid effluents for the period contributed to only a small fraction of the LaSalle County Technical Specification / Stand ards limits. Calculations of environmental concentrations based on effluent, Illinois River flow, and meteorological data for the period indicate that consumption by the public of radionuclides attributable to LaSalle County Station does not exceed regulatory limits. Radiation exposure from radionuclides released to the atmosphere represented the critical pathway for the period with a maximum individual total dose estimated to be 4.33E-03 mrem for the year, where a shielding and occupancy factor of 0.7 is assurned.

The assessment of radiation doses is performed in accordance with the Comed Offsite Dose 4 Calculation Manual (ODCM). The results of analysis confirm that the station is operating in compliance with 10CFR50 Appendix I,10CFR20 and 40CFR190.

1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosobere Measured concentrations of noble gases, radioiodine, and particulate radioactivity released to the atmosphere during the year, are listed in Table 1.1-1. A total of 1.17 E+03 curies of fission and activation gases was released with a maximum quarterly average releasc rate of 6.50E+01 pCi/sec.

A total of 1.16E-01 curies of I-131 was released during the year with a maximum quarterly average release rate of 1.33E-02 pCi/sec for all iodines.

A total of 2.42E-03 curies of beta-gamma emitters was released as airborne particulate matter with a maximum quarterly average release rate of 2.26E-04 pCi/sec. Alpha emitting radionuclides were not measurable.

A total of 5.34E+01 curies of tritium was released with a maximum quarterly average release rate of 2.94E+0 pCi/sec.

1.2 Liquids Released to Illinois River A total of 1.68E+05 liters of radioactive liquid waste (prior to dilution), containing 1.00E-02 curies (excluding tritium, noble gases and alpha) were discharged from the station. These wastes were released at a maximum quarterly average concentration of 3.38E-05 pCi/ml. A total of 3.88E-01 curies of tritium was released. Quarterly release totals of principal radionuclides in liquid effluents are given in Table 1.2-1.

2.0 SOLID RADIOACTIVE WASTE Solid radioactive wastes were shipped by truck to Barnwell, South Carolina. The record of waste shipments is summarized in Table 2.0-1.

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways Table 3.1-1 summarizes the doses resulting from releases of airborne radioactivity via the different exposure pathways.

3.L1 Noble Cases 3.1.1.1 Gamma Dose Rates Offsite Gamma air and whole body dose rates 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 for the year are shown in Figure 3.1-1. Based on measured effluents and meteorological data, the maximum dose to an adult would be 4.33E-03 mrem for the year, with an occupancy or shielding factor of 0.7 included, and based on measured effluents and concurrent meteorological data would be 4.74E-03 mrem. The maximum gamma I

3

air dose was 5.73E-03 mrad, and 1.69E-02 mrad based on concurrent meteorological data.

3.1.1.2 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 the purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive skin tissues is difficult to calculate due to the effect of the beta particle energies, thickness of inert skin and clothing covering sensitive tissues.

For pur 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 4.69E-03 mrem. The maximum offsite beta air dose for the year was 4.27E-04 mrad.

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

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 plant, 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 milk by an infant.

3.1.2.1 Iodine Concentrations in Air The calculated concentration contours for iodine 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 offsite concentration is estimated to be 1.71E-03 pCi/m3 for the year.

3.1.2.2 Dose to Infant's Thyroid The hypothetical thyroid dose to an infant living near the station 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 through October. The maximum infant's thyroid dose was 6.62E-02 mrem during the year (Table 3.1-1).

3.1.3 Concentrations of Particulates in Air Concentration contours of radioactive airborne particulates are shown in Figure 3.1-4. The maximum offsite average level is estimated to be 3.79E-05 pCi/m3, 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 4

aquatic environment. NRC-developed equations

were used to calculate the doses to the whole body, lower GI tracts, thyroid, bone, skin; specific parameters for use in the ec uations are given in the Comed Offsite Dose Calculation Manual. The maximum w note body dose for the year was 1.09E-04 mrem and no organ dose exceeded 1.64E-04 mrem (Table 3.2-1).

3.3 Assessment of Dose to Member of Public During the period January to December,1996, LaSalic County Station did not exceed these limits as shown in Table 3.1-1 and Table 3.2-1 (based on yearly average meteorological data), and as shown in Figure 3.1-1 (based on concurrent meteorological data), and as shown in Table 3.3-1:

The RETS limit.. on dose or dose commitment to an individual due to radioactive materials in liquid effluents from each reactor unit (1.5 mrem to the whole body or 5 mrem to any organ during any calendar quarter; 3 mrem to the whole body or 10 mrem to any organ during any calendar year).

The RETS limits on air dose in noble gases released in gaseous effluents to a member of the public from each reactor unit (5 mrad for gamma radiation or 10 mrad for beta radiation during any calendar quarter; 10 mrads for gamma radiation or 20 mrad for beta radiation during any calendar year).

The RETS limits on dose to any individual due to iodine-131, iodine-133, tritium, and radionuclides in particulate form with half-lives greater than eight days in gaseous effluents released from each reactor unit (7.5 mrem to any organ during any calendar quarter; 15 mrem to any organ during any calendar year).

The 10CFR20 limit on Total Effective Dose Equivalent to individual members of the public (100 mrem).

4.0 SITE METEOROLOGY A summary of the site meteorological measurements taken during each calendar quarter of the year is given in Appendix II. The data are presented as cumulative joint frequency distributions of the winct direction for the 375' level and wind speed class by atmospheric stability class determined for the temperature difference between the 375' and 33' levels.

Data recovery for these measurements was about 99.8% during 1996.

5.0 ENVIRONMENTAL MONITORING Table 5.0-1 provides an outline of the Radiological Environmental Monitoring Program (REMP) as required in the current Technical Standards. Tables 5.0-2 lists the program's sampling locations, collection frequencies and analyses for all samples collected. Tables

5.0-3 to 5.0-6 sununarize 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 j

! inspection at the Station.

i Specific findings for various environmental media are discussed below.

5.1 Gamma Radiation ,.

External radiation dose from onsite sources and noble gases released to the !

atmosphere was measured using CaSO4:Tm thermoluminescent dosimeters (TLDs). j Each location normally consists of 2 TLD sets. The quarterly average external radiation dose for the year was 16.7 mR at the indicator locations and 14.7 mR at the :

control locations. 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 fourteen air sampling locations averaged 15.9 mR and is similar to levels measured in 1986 (17.1 mR),1987 (17.8 mR),1988 (16.5 mR),

1989 (17.6 mR),1990 (17.8 mR),1991 (17.7 mR),1992 (15.5 mR),1993 (14.5 mR),1994 .

!' (15.4 mR) and 1995 (15.3). These differences are not statistically significant.

1 5.2 Airborne 1-131 and Particulate Radioactivity Locations of the samplers are shown in Figure 5.0-3. Airborne I-131 remained below the LLD of 0.07 pCi/m3 throughout the year.

i l 1

Gross beta concentrations ranged from 0.006 to 0.042 pCi/m3and averaged 0.021 l pCi/m3 and is similar to levels measured in 1985 (0.025 pCi/m3),1986 (0.027 pCi/m3, except for the period from May 16 through June 6 when it was influenced by j the nuclear reactor accident at Chernobyl),1987 (0.027 pCi/m3 ),1988 (0.031 pCi/m3), ;

1989 (0.028 pCi/m3),1990 (0.024 pCi/m3), and the same as in 1991 (0.022 pCi/m3 ),

I 4 1992 (0.022 pCi/m3 ),1993 (0.022 pCi/m3) ,1994 (0.022 pCi/m )3 and 1995 (0.021 I

pCi/m3),

Gamma isotopic results were below the LLD level of 0.01 pCi/m3 in all quarterly composites.

No activity attributable to station operation was detected in any sample.

5.3 Ac.uatic Radioactivity .

Well water was collected quarterly from one onsite well and one offsite well and analyzed for tritium and gamma-emitting nuclides. All results were below the limits

! of detection, indicating that there was no measurable amount of radioactivity due to j the Station's releases.

Weekly surface water samples from the Illinois River at Seneca and Illinois River Downstream were composited monthly and analyzed for gamma and beta-emitting nuclides. Weekly samples from the same locations were composited quarterly and analyzed for tritium. None of the composited samples indicated the presence of gamma-emitting nuclides above their respective LLD levels.

Gross beta activity averaged 5.2 pCi/L in the Illinois River at Seneca samples, with a range of 4.0-7.0 pCi/L. The Illinois River, Downstream sample averaged 5.8 pCi/L, with a range of 4.7-7.3 pCi/L.

6 i

Tritium was detected in the quarterly upstream samples, Illinois River at Seneca, in the first, second and fourth quarters at a maximum fourth quarter concentration of 616 pCi/L. In the Illinois River Downstream samples, tritium was detected in the first and fourth quarters at a maximum fourth quarter concentration of 384 pCi/L These values are well below the reporting level of 30,000 pCi/L.

Sediment samples were collected twice a year from one indicator location (Illinois River, Downstream) and analyzed (c,r gamma-emitters. All gamma-emitters were below their respective detection limits in both samples. There are no adverse effects expected to the environment.

Levels of gamma radicativity in fish were measured and found in all samples to be below the lower limit of detection for the program.

5.4 Milk Milk samples were collected monthly from November through April and biweekly from May through October and analyzed for Iodine-131 and gamma-emitting nuclides.

1-131 remained below the detection limits of 0.5 pCi/L (May - October) and 5.0 pCi/L (November - April). Cs-134, Cs-137 and Ba/La-140 were below the LLD levels of 15, 18 and 15 pCi/L, respectively.

5.5 Terrestrial Radioactivity Vegetables were collected in the third quarter and analyzed for gamma-emitting nuclides. In addition, green leafy vegetables were analyzed for I-131. All nuclides were below the limits of detection, indicating there was no measurable amount of radioactivity attributable to the Station's releases.

5.6 Sample Collections All samples were collected as scheduled except those listed in the Listing of Missed Samples, Appendix III.

5.7 Program Modifications In the second quarter of 1996 it was discovered that air sampling location L-12 had been misidentified in the ODCM as an indicator location. It should have been a control location. Subsequently, L-04 was reactivated as an indicator location and L-12 became a control location. (L-04 had been removed as an indicator location with the implementation of UREMP.)

In August of 1996, L-41 (Burton Farm) removed itself from the environmental monitoring program.

6.0 ANALYTICAL PROCEDURES Procedures used during the period covered in this report remained unchanged. A summary of the procedures used for analyzing radioactivity in environmental samples is given in Appendix VI of the report for the period January - December 1993.

Annendir V Interlaboratory Cnmnaric.nn Proaram Resub 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 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 current year. This program is conducted by the U.S. Environmental Protection Agency Office of Research and Developement National Exposure 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 mixed analyte performance evaluation program.

Table A4 list results of the Environmental Measurement Laboratory Quality Assessment Program.

Out-of-limit results are explained directly below the result.

APPENDIX VI ERRATA DATA 1

VI-1 1

l

ERRATA DATA 1.0 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 assess measurements of environmental radiation for those TLDs. This is required by section 5.3.1 of the ODCM.

Corrective action was begun with the second quarter of 1997, during which Comed populated its stations' direct environmental locations with its own environmental TLDs as well as with TLDs supplied by a vendor. The vendor's environmental TLD program does comply with section 5.3.1 of Comed's ODCM. Comed will develop an I interlaboratory comparison program for its own environmental TLDs and will comm> ce interlaboratory comparison as soon as its program is satisfactorily developed. The TLD records for environmental monitoring will be Comed's TLDs, provided we have I successfully implemented the interlaboratory comparison program. Otherwise, the vendor's TLDs will be Comed's environmental dose of record.

2.0 In the first, second and third quarters of 1996 at LaSalle County Station, TLD locations I L-211-1 and L-211-2 were monitored using spare TLDs during quarterly exchanges. Due to a discrepancy in the Teledyne Sampling Procedures Manual, the sample collector did not record the serial number of the spare TLDs on the TLD Check-off Sheet. As a I result, the dose to the locations could not be determined. The manual (Section 6.12.3.4.c) instructs the collector to " record the date, time and location of the replacement..."

To prevent recurrence of this situation a memo was sent to all sample collectors on January 10,1997, instructing them to record the serial number of any spare TLDs placed in the field. A revision will be made to the Teledyne Sampling Procedures Manual, on or before June 30,1997, to include this information.

3.0 In 1996, according to the LaSalle County Station ODCM, vegetation samples were to be collected three times annually from two indicator locations and one control location. At I least two samples were to be collected each time. According to the Teledyne Sampling Procedures Manual, these samples should contain one broad leaf vegetable and one root vegetable,if available.

Two locations were sampled in 1996, Ettema's Farm (existing location L-42) and 408 Plumb St., but only Ettema's Farm was sampled three times. After a diligent search, l

B the sample collector found 408 Plumb St., however, the one collection from this location depleted the supply of vegetables. The collector was unable to locate another site.

g The collector also had problems finding a control location and did not obtain vegetables from Eugene Clements' garden until October 14,1996. Due to the lateness of the season, l he could only manage one collection from this location. There were no root vegetables available at this site.

An unusually late and rainy spring in 1996, lack of available large farms in the vicinity of LaSalle County Station, anc. small private gardens with little yield were problems cited by the collector.

To help prevent recurrence of this situation, LaSalle County Station made a change in

[ their ODCM requiring vegetation collections once a year instead of three times. The sample collector will be encouraged to start a diligent search for viable locations early in the planting season or, the station itself may choose to plant a garden onsite as an indicator location.
