INTRODUCTION LaSalle Station, a two-unit BWR plant is located near Marseilles, Illinois, in LaSalle County, 3.5 miles south of the Illinois River. Each reactor is designed to have a capacity of 1078 MW net. Unit No. 1 loaded fuel in March 1982. Unit No. 2 loaded fuel in late December 1983. The plant has been designed to keep releases to the environment at levels below those specified in the regulations.

Liquid ef fl uents 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 af ter delay to pennit decay of short half-life gases. Releases to the atmosphere are calculated on the basis of analyses of routine grab samples of noble gases and continuously collected composite samples of iodine and particulate matter. The results of effluent analyses are sumarized on a monthly basis and reported to the Nuclear Regulatory Commission as required per Technical Specifications. Airborne concentrations of noble gases, 1-131 and particulate radioactivity in offsite areas are calculated using effluent and meteorological data.

Environmental monitoring is conducted by sampling at indicator and reference (control). locations in the vicinity of the LaSalle County Station to measure changes in radiation or radioactivity levels that may be attributable to plant operations. _ If significant changes attributable to LaSalle County Station are measured, these changes are correlated with effluent releases. External ganna radiation exposure from noble gases and 1-131 in milk are the most critical pathways at this site; however, an environmental monitoring program is conducted which includes other pathways of less importance.

SUMMARY

Gaseous and liquid effluents for the period remained at a fraction of the Technical Specification 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 the plant are well below the 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 2.15E-04 mrem for the year, when a shielding- and occupancy f actor of 0.7 is assumed. The assessment of radiation doses is performed in accordance with the Offsite Dose Calcula-tion Manual (00CM). The results of analysis confirm that the station is operating in compliance with 100FR50 and 40CFR190.

i 1.0 EFFLUENTS 1.1 Gaseous Effluents to the Atmosphere 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 6.87E+02 curies of fission and activa-tion gases was released with an average release rate of 7.55E+01 pCi/ sec .

A total of 2.17E-03 curies of 1-131 was released during the year, with an average release rate of 1.75E-04 pCi/sec for all iodines.

A total of 1.27E-03 curies of beta-gamma emitters were released as airborne particulate matter, with an average release rate of 2.11E-04 pCi/sec. Alpha emitting radionuclides were not measurable.

A total of 1.70E-01 curies of tritium was released, with an average release rate of 8.37E-03 pCi/sec.

1.2 Liquids _ Released to the Illinois River A total of 4.07E+05 liters of radioactive liquid waste (prior to dilution) containing 2.46-02 curies (excluding tritium, gases, and al pha) were discharged after dilution wi th a total of 3.12E+08 liters of water. These wastes were released at a quarterly average concentration of 2.05E-06 pCi/ml, discharged on an unidentified nuclide basis. A total of 2.08E-01 curies of alpha radioactivity and - 3.74E-01 curies of tritium were released. Quarterly release estimates in liquid effluents are given in Table 1,2-1.

2.0 SOLID RADI0 ACTIVE WASTE Solid radioactive wastes were shipped by truck to Oak Ridge, Tennessee; Beatty, Nevada; Waltz Mill, Pennsylvania; Barnwell Nuclear Center, South Carolina; and Channahon, Illinois. The record of waste shipments is sunnarized in Table 2.0-1.

3.0 DOSE TO MAN 3.1 Gaseous Effluent Pathways Gamma Dose Rates Gamma air and whole body dose rates offsite were calculated based on measured release rates, isotopic composition of the noble gases, and meterological data for the period (Table 3.1-1). Isodose contours of whole body dose are shown in Figure 3.1-1 for the year.

I Based on measured ef fl uents and meteorological data, the maximum dose to an individual would be 2.15E-04 mrem for the year, with an occupancy or shielding factor of 0.7 included. The maximum gamma air dose was 4.08E-04 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 clothino 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 1.25E-03 mrem. The maximum of fsite beta air dose for the year was 1.41E-03 mrad.

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

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 radionuclide is ingestion of radioiodine in milk by an infant.

Iodine-131 Concentrations in Air The calculated concentration contours for 1-131 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 el emental iodine deposition cn the ground. The maximum offsite concentration is estimated to be 3.43E-04 pCi/m3 for the year.

Dose to Infant's Thyroid The hypothetical thyroid dose to an inf ant living near the plant via ingestion of milk was calculated. The radionuclide considered was 1-131 and the source of milk was taken to be the nearest dairy farm with the cows pastured from May to October. The maximum inf ant's thyroid dose was 3.64E-03 mrem during the year (Table 3.1-1).

Concentrations of Particulates in Air Concentration contours of radioactive ai rborne particulates are shown in Figure 3.1-4. The maximum offsite level is estimated to be 1.44E-05 pCi/m3 Summary of Doses Table 3.1-1 sumarizes the doses resulting from releases of airborne radioactivity via the different exposure pathways.

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

,norel i ne . Not all of these pathways are applicable at a given time or statien 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 equations were used to calculate the doses to the whole body, lower G1 tract, thyroid, bone and skin; specific parameters for use in the equations are given in the Commonwealth Edison Offsite Dose Calcu-lation Manual. The maximum whole body dose for the year was 4.18E-05 mrem and no organ dose exceeded 3.24E-05 mrem.

3.3. Direct Radiation In section 3/4.11 of the LaSalle Technical Specifications, 40CFR190 calculations of total dose due to the Uranium fuel Cycle are required only when calculated doses from liquid or gaseous releases of radio-activity exceed certain levels. These levels are twice the following limits :

o The RETS limits on dose or dose commitment to an individual due to radioactive materials in liquid ef fluents f rom each reactor unit (1.5 mrems 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).

Huclear Regulatory Commission, Regulatory Guide 1.109 (Rev.1).

i 5

4 1 1

i a The RETS-limits on air dose in noble gases released in gaseous ef fluents to a member of the public f rom each reactor unit (5 mrad for gamma radiation or 10 mrads -

for beta radiation during any calendar quarter; 10 mrads for gamma radiation or 20 mrad for beta radiation during any calendar year).

o 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 mrems to any organ during any calendar quarter; 15 mrems to any organ during any calendar year).

During the period January-to December,1990, LaSalle County Station did not exceed these criteria, and members of the public (occasional visitors to the site) did not exceed these criteria either when onsite.

4.0 SITE METEOROLOGY A sumary of the site meteorological measurements taken during each quarter of the year is given in Appendix 11. The data are presented as cumulative joint frequency distributions of 375' and 33' levels. Data recovery for these measurements was about 98.9%.

5.0 ENVIRONMENTAL MONITORING Table 5.0-1 provides an outline of _the Radiological Environmental Moni-toring Prooram as required in the Technical Specifications. _ Tables 5.0-3 to 5.0-6 summarize data for the year. Except for tables of special interest, tables listing all data are no longer included in the annual repo rt . All data tables are available 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 onsite sources and noble gases released to the atmosphere was measured at ten indicator and four reference (background) -locations using CaSO4 :0y thermoluminescent dosimeters (TL0s). A comparison of the TLD results for reference stations with' onsite and offsite indicator stations is included in Table 5.1-1. A total of forty-eight additional TL0s were installed on June 1,1980 such that each sector was covered at both five miles and the site boundary. Six (6) TLD locations were added to the monitoring program on July 1,1985.

6

l Quarterly external radiation dose at fourteen air sampling locations averaged 17.8 mR) and was similar to levels measured in 1986 (17.1 mR),1987 (17.8 mR),1988 (16.5 mR), and 1989 (17.6 mR) . The differences are not statistically significant.

5.2 Airborne 1-131 and Particulate Radioactivity Locations of the samplers are shown in Ngure 5.0-1. Airborne 1-131 remained below the LLD of 0.10 pCi/m4 throughout the year.

Gross beta concentrations ranged from 0.010 to 0.079 pCi/m3 and averaged 0.024 pCi/m3 and was slightly lower than in 1985 -(0.025 pCi/m3), 1986 (0.027, except for the period from May 16 through June 6 when it was influenced by the nuclear reactor accident at 1987 (0.027 pCi/m3), 1988 (0.031 pCi/m3), and 1989 Chernobyl),3 (0.028 pCi/m .

Gamma-emitting isotopes were blow the LLO level of 0.01 pCi/m3 in all quarterly composites.

No radioactivity attributable to plant operation was detected in any s ample .

5.3 Terrestrial Radioactivity Well- water was collected quarterly from one onsite well and five offsite wells and analyzed for tritium and gamma-emitting isotopes.

All results were below the limits of detection, indicating that there was no measurable amount of radioactivity due to the Station's releases.

5.4 Aquatic Radioactivity Weekly surface water samples from the Illinois River at Seneca and LSCS Cooling Lake were composited monthly and analyzed for gamma-emitting isotopes. Weekly samples from the sane locations were composited quarterly and analyzed for tritium. None of the com-posited samples indicated the presence of gamma-emitting isotopes above their respective LLD levels. Tritium was detected in five samples and ranged from 226 to 294 pCi/L. Similar results were obtained in 1988 and 1989.

Sediment samples were coll ected twice a year from one indicator location (downstream _ at Cooling Lake) and analyzed for gamma-emitters. Gamma-emitters were below their respective detection limits in all samples.

7

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

5.5 Milk Milk samples were collected monthly from November through April and weekly from May through October and analyzed for iodine-131 and gamma-emitting isotopes.

1-131 remained below the detection limit of 0.5 pC1/L.

Cs-134 and Cs-137 were below the LLD level of 5 pCi/L. All other gamma-enitting isotopes, except naturally-occurring K-40, were below their respective LLDs. There was no indication of the effect on the environment due to station operation.

5.6 Sample Collections All samples were collected as scheduled except those listed in the Listing of Missed Samples, Appendix 111.

5.7 Program Modifications Boldt Dairy (L-18) was replaced by Flatness Dairy. Gass Farm (L-20) was added to the program in November,1990; the additional dairy was not required by the ODCM but was added to the program to ensure that the program included at least four dairies.

6.0 ANALYTICAL PROCEDURES A sunnary of the procedures used for analyzing radioactivity in environ-mental samples is given in Appendix V of - the report for the period January - December 1988. Procedures used during the period covered by this report remained essentially unchanged.

7.0 - MILCH ANIMALS AND NEAREST CATTLE CENSUSES A census of milch animals was conducted within five miles of the station.

The survey was conducted by a " door-to-door" canvas and by information from Illinois Agricultural Agents. The census was conducted by A. Lewis on June 13 and 14, 1990. The nearest cattle census was conducted by A.

Lewis on July 10,11, and 12,1990.

8

8.0 NEAREST RESIDENCES CENSUS A census of the nearest residences within a five (5) mile radius was conducted by A. Lewis on June 27, 1990.

Results of milch animals, nearest cattle, and nearest residence censuses are presented in Appendix IV.

9.0 INTERLABORATORY COMPARISON PROGRAM RESULTS Interlaboratory Comparison Program Results are presented in Appendix V.

APPENDIX V INTERLABOR ATORY COMPARISON PROGR AM RESULTS 90

i Appendix V Interlabor0 tory Comparison Program Results Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) 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 environmentel-type samples (e.g., milk or

~ water) -containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The. pu

- provide an independent check on the laboratory,rpose s analyticalof such a program procedures and is to to

' alert it to any possible problems.

Participant laboratories measure the concentrations 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 environ.

mental sample crosscheck program for mil k,- water,- air- filters, and food samples

- during the~ period January 1986 through December,1990. This program has been ;

(. conducted by the U.S. Environmental Protection Agency Intercomparison and ;

Calibration St:ction - Quality Assurance Branch, Environmental Monitoring and Support Labort. tory, Las Vegas, Nevada. ;

.Th'e- results. in Table ' A-2 were obtained for thermoluminescent dosimeters - (TLDs) during the teriod.1976,1977,1979,1980,1984, and .1985-1986 through partici-

..pation in-. tne 1Second, Third, Fourth, Fif th, Seventh, and Eighth International Intercomparison -of Environmental Dosimeters under the sponsorships listed in Table A-2.. Also Teledyne testing results are listed.

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

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

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

EPA TIML Control Result Limit Lab Code Analysis (pCi/L)a (pCi/L)o Expl anation STM-504 S r-89 57.014.3 60-3-77.7 Milk had high f at content which Sr-90 32.0 1.0 32.4-37.6 made analyses dif ficult. Ad-dition of errors to TIML result would put values within EPA control limits. EPA also had the same problem in analyzing its own sample.

STW-511 Ra-228 8.111.4 .6-8.0 TIML 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 wi thin EPA control limits and TIML will monitor the situation in the future.

STF-524 K 1010.71158.5b 1123.5-1336.5b Error in transference of data.

Correct data was 1105133 mg/kg.

Results in the past have been within the limits and TIML will monitor the situation in the future.

STW-532 I-131 9.0 2.0 6.2-8.8 Sample recounted t.f ter 12 days.

The average result was 8.821.7 pCi/L (within EPA control limits). The sampl e was recounted in order to check the decay. Results in the past have been within the limits and TIML will continue to monitor the situation in the future, a Reported in pCi/L unless otherwise noted.

b Concentrations are reported in mg/kg.

ADDENDUM TO APPENDIX A (continued) l EPA TIML Control Result limit Lab Code Analysis (pCi/L)a (pCi/L)a Explanation STW-534 Co-60 63.321.3 41.3-58.7 High level of Co-60 was due to contamination of beaker. Beaker was discarded upon discovery of I contamination and sample was recounted. Recount results 53.213.6 and 50.922.4 pCi/L.

STM-554 Sr-90 51.022.0 54.8-65.2 The cause of low result was due to very high fat content in the mil k, it should be noted that 63% of all participants failed this test. Also, the average for all participants was 54.0 pCi/L before the Grubb and 55.8 pCi/L af ter the Grubb.

STW-560 Pu-239 5.8 1.1 3.5-4.9 The cause of high results is not known it is suspected that the standard was not properly calibrated by supplier and is under investigation. New Pu-236 standard was obtained and will be used for the next test.

STW-568 Ra-228 2.611.0 2.7 -4 .5 The cause of low results is not known. Next EPA crosscheck results were within the control limits. No further action is planned.

STM-570 Sr-89 26.0210.0 30.3-47.7 The cause of low results was Sr-90 45.724.2 49.8-60.2 falsely high recovery due to suspected incomplete calcium removal. Since EPA sample was used up, internal spike was prepared and analyzed. The results were within control limits (See table A-3, sample QC-MI-24). No further action is planned, a Reported in pCi/L unless otherwise noted.
