h INTRODUCTION: The La Crosse Boiling Water Reactor (LACBWR), also known as Genoa Station No. 2, is located on the east bank of the Mississippi River near Genoa, Vernon County, Wisconsin. The plant was designed and constructed by the Allis-Chalmers Manufacturing Company. It was completed in 1967 and had a generation capacity of 50 MW (165 MW(th)). The reactor is owned by Dairyland Power Cooperative (DPC). The reactor went critical in July 1967 and first contributed electricity to DPC's system in April 1968. After completing full w wer tests in August 1969, the plant operated between 60% and 100% full power, with the exception O .ef e1 ant shetdewns ter maintenance and rereir. In April'of 1987 plant operation was ceased. The reactor is presently defueled and work is progressing to placo'the plant into a SAFSTOR mode. In August of 1987 a possession-only licenso was received. In accordance with LACBWR Technical Specifications 6.9.3.a & 6.9.3.b and in' compliance with 10 CFR.50.36a(a)(2), this document is the Radioactive Effluent Report for the period January 1 through December 31, 1990. v] / 1-

L - (~) EFFLUENT AND WASTE DISPOSAL REPORT N (Supplemental Information) FACILITY: Lacrosse Boiling Water Reactor LICENSEE: DAIRYLAND POWEP. COOPERATIVE DOCKET NO. 50-409 1. REGUIATORY LIMITS Gaseous Effluent Release Limits: a. LACBWR's Technical Specifications for gaseous effluent releases of radioactive material limit the release rates of the sum of the individual radionuclides, in Curies per second, so that the dose rates to members of the public beyond the Effluent Release Boundary do not exceed 500 mrem / year to the whole body, 3000 mrem / year to the skin from noble gases, and 1500 mrem / year to a critical organ from H-3, I-131/133 i and particulates with half-lives greater than 8 days. also, in accordance with 10 CFR 50, Appendix I, the Technical Specifications for gaseous effluent radioactive material limit the air dose to a member of the public from noble gases in areas beyond the -Effluent Release Boundary to less than 5 mrad gamma and 10 mrad beta por calendar quarter, and less than 10 mrad gamma and 20 mrad beta per calendar year. The dose limits from H-3, I-131/133 and particulates with half lives greater than 8 days are less than 7.5 mrem per calendar quarter, and less than 15 mrem per calendar year to any organ. l, Cumulativo dose contributions from gaseous effluent releases are f determined in accordance with the LACBWR Offsite Dose Calculations Manual. 2-

b. Liquid Effluent Release Limits: 7g L) LACBWR's Teeb-11 Specifications limits for liquid effluent releases are limited to those concentrations of indivioral radionuclides such that the diluted discharge does not exceed 1 MPC it a 168-hour week averaged over the calendar year. For dissolved or er'. rained noble gases, the concentration is limited to a total a;tivity concentration of 2 x 10'" pCi/ml. For alpha emitting radionvalides, the concentration is limited to a total activity concentration of 4.9 x 10** pCi/mi, based upon an actual alpha emitting radionuclide analysis performed on a representative water sample. The values reported in tables 2A and 2B, Liquid Effluents, are based on dilution with the combination of LACBWR and Genoa Station No. 3 condenser cooling water flow prior to discharge to the Mississippi River. No credit is taken for further dilution in O the mixing zone of the Mississippi River. ,G Also, in accordance with 10 CFR 50, Appendix I, the dose commitment to a member of the public from radioactive materials released in liquid effluents to areas beyond the Effluent Release Boundary are limited to less than 1.5 mrem whole body and 5.0 mrem organ dose por calendar quarter, and less than 3.0 mrem whole body and 10 mrem organ dose per calendar year via the critical ingestion pathway. Cumulative quarterly and annual dose contributions from liquid effluent releases are determined for the adult fish ingestion pathway in accordance with the LACBWR Offsite Dose Calculation Manual.

1 c. Solid Radioactive Waste All solid radioactive wastes are handled in accordance with a Process Control Program as defined by LACBWR procedures in order to assure that all applicable transportation and burial site disposal requirements are met. 2. MAXIMUM PERMISSIBLE CONCENTRATION (MPC) The MPC used to calculate permissible release rates are obtained from 10 CFR 20, Appendix h, Tables I and II. In addition, the following values are used: Tritium in Water = 3 x 10*8 pC1/ml. 2 x 10 7 pCi/cc. Tritium in Air a 3. AVERAGE ENERGY The release rate limits for LACBWR are not based on average energy. 4. ANALYTICAL METHODS a. Liquid Ef1.'ents -Liquid effluent measurements for gross radioactivity are performed by Go-Li gamma isotopic analysis of a representative sample from each tank discharged. A composite sample is created by collecting representative aliquots of each sample from cach tank batch discharged, and is analyzed monthly for Tritium, and quarterly for Iron-55 and Strontium 89 & 90. The iron and radiostrontiums are analyzed by a contractor. In addition, each batch discharged tank is analyzed for alpha activity concentration and tritium..-

b. Airborne Particulates Airborne particulate releases are determined by Go-Li gamma isotopic analysis. This analysis is performed by analyzing a glass fiber filter paper taken from the stack monitor (Eberline SPING) which continuously isokinetically samples and monitors the stack effluent. This filter is changed end analyzed on an approximate weekly basis and analyzed within 7 days after removal. This filter is alsc analyzed for alpha activity. A quarterly composite of these filters is sent to a contractor for Sr 89 and 90 analysis, c. Radiolodines Radiciodine releases are determined by Go-Li gamma analysis of a TEDA impregnated activated charcoal cartridge taken from the stack nC monitor which continuously isokinetically samples and monitors the stack effluent. This charcoal cartridge is changed approximately weekly and analyzed within 48 hours after removal. Since the plant shutdown in April 1987, the I-131/I-133 have decayed completely to stable elements, d. Fission and Activation Gases The gaseous releases converted into concentration (pCi/cc) are continuously sampled from the stack release flow by two stack monitors, which are inline monitors. These gas concentrations (pCi/cc) are averaged by the monitors microprocessor and flowrate/ pressure compen-sated to obtain the daily gaseous release of the plant. Since the plant l shutdown in April 1987, gaseous releases have been immeasurable. All fission gases.except Kr-85 have decayed completely to stable elements. l O 1 -

v(). e. Tritium Tritium releases are determinad by taking a grab sample of the stack atmosphere at the effluent of the stack monitor. Tritium, as tritiated water, is removed from the sample stream by condensation, using a cold trap containing an organic compound and dry ice. The condensed water vapor is then distilled and the distillate is analyzed for H-3 concentration, pCi/ce, by internal liquid scintillation spectrophotometry and the results are expressed in terms of tritium release rates. The tritium grab samples are obtained on at least a once/ month basis unless the upper reactor cavity is flooded, at which time the sampling frequency is increased to at least once per 7 days. c L-5. BATCH RELEASES-AV a. Airborne All airborno effluent releases at LACBWR are from a single Continuous-Elevated Releasa Point. b. Liould All liquid effluent releases at LACBWR are batch releases.

SUMMARY

AND CONCLUSIONS: a. Gaseous Effluent Releases The maximum quarterly offsite gamma dose due to nobic gases was 0.00 mrad. The cumulative 1990 annual offsite gamma dose due to noble gases was 0.00 mrad. The maximum quarterly offsite beta dose due to noble gases was 0.00 mrad. The cumulativo 1990 annual offsite beta dose due to nobic gases was 0.00 mrad. The maximum quarterly offsite dose to any organ from the release of I-131, 1-133, H-3 and all radionuclides in particulate form with half-lives greater than 8 days was approximately 9.09E-4 mrem. The cumulative 1990 annual maximum organ dose from these radionuclides was approximately 2.02E-3 mrem. The highest historical monthly and annual average X/Q's for the period 1985-1987 for the worst case offsite receptor location, in accordance with the ODCM, were used to calculate these offsite dose values. b. Liquid Effluent Releases The maximum quarterly organ dose from liquid releases was approximately 3.65E-3 mrem. The maximum cumulative 1990 annual organ dose was approximately 1.06E-2 mrem. The maximum quarterly whole body dose for liquid releases was approximately 2.43E-3 mrem, and the cumulative 1990 annual whole body dose was approximately 7.07E-3 mrem. c. Conclusion All calculated offsite doses were below Technical Specification limits. O l

O ~ INTRODUCTION: The Radiological Environmental Ho- .g (REH) Program is conducted to comply with the requiremenu c1 Technica. a s..fications and in accordance with 10 CFR $0 Appendix 1. The REM Program provides measutements of radiation and of radioactive materiale in those exposure pathways and for those radionuclides which could potentially lead to radiation doses to Hembers of the Public resu1 ting fron, plant ef fluents. Environmental samples are taker eathin the surrounding arcan of the plant and in, elected contro1 or background locations. The monitoring program at the IACWR f acility includes monitoring of O iieuid aed aeseous re1 eases from the P aet. as ue11 as environmentai samries 1 of surface air, river water, river sediment, milk, fish, and penetrating radiation. 4 The REM program theory supplements the Radioactive Ef fluent analyses by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways using the methodology of the Offsite Dose Calculation Manual (ODCH). An Interlaboratory Comparisan Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmentai sampics are performed to demonstrate that the results are reasonab1y valid. l

This monitoring report includes the period from January 1, 1990, to Decembe.* 31, 1990. The report includes a description-of the environmental san ule collected, analytical methods, statistical inferences, and the results from these analyses. A series of maps of the general vicinity surrounding LACBWR are provided for the reader so that he/she may determine the spatial relationship of the plant to the surroanding area. Figure 1 is a map that includes the plant boundary, roads, other generating plants, and the relation of the plant site to the nearest local consnunity. Figure 2_is a map that pinpoints the location of the environmental sampling stations for surface air, and milk. Thi map when used with Yable 6 will allow the reader to determine the spatial relationship of the plant to the surrounding sampling stations. Environmental direct radiation monitor (TLD) locations for 1990 can be found by refer"ing to Figure 3 and 4 and Table 7. 1.0 SAMPLE COLLECTION The sampling frequency of the various environmental samples and the analyses performed on these samples are shown in Table 5. The number of various samples collected and analyzed during 1990 is shown in Table 8. The environmental penetrating radiation dose is measured by thermo-i luminescent dosimeters consisting of four lithium fluoride (LiF) chips. The 0 [

(J TLD's are located in the vicinity of the plant on poles, trees or adjacent to air sample locations. The TLD's are collected, shipped and then analyzed by a contractor. 2 r Air sampics are collected continuously at seven sites, six of which are within three miles of the plant and the seventh used as a control, located eighteen miles north of the plant in La Crosse, Wisconsin. Particulate air samples are collected at the rate of approximately 30-60 1pm with Galinan Air Samples. The 'tr filter consists of a glass fiber filter with an associated pore size of approximately 0.45 pm. The particulate filters are analyzed for gross beta activity with an internal proportional counter, and the monthly particulate composites are gamma analytod for individual isotopic concentra-tion. Addendum 64 to the LACBWR Technical Specifications was issued in ( December of 1988. This addendum eliminated the requirements to sample the air for I-131 due to the stablilization of all iodine at LACBWR. I River water is collected monthly. River water samples-above, at'and 1 below the plant site are collected and are gamma analyzed for isotopic concentration. .5 A one-liter' milk sample ir. collected from three farms in the vicinity of the plant on a biveckly basis during the grazing season. The milk samples are gamma-scanned for any isotope with at Icast at. uight-day half life. O l l

I t Fish samples are collected on a quarterly basis irom Pool #8 above the plant or Pool #9 below the plant. Sampics of the edibic portions of the fish are gamma isotopically analyzed, l t ove and h River sediment (silt) samples are collected twice per year ai., below the Genoa-3 condenser cooling water discharge point in Pool #9. These samples are gamma isotopically analyzed. Vegetation was collected from the local gardens at the time of harvest. These samples are gamma isotopically analyzed. 2.0 RESULTS OF THE 1990 RADIO-ENVIRONMENTAL MONITORING SURVEYS l During 1990, activity 1cvels in the local environment vera normal, indicating no significant plant attributed radioactivity. 2.1 PENETRATING RADIATION The environmental TLD's are changed on a quarterly basis and are sent to an outside contractor for reading. The results of this survey program are shown on Table 9. These badges have been divided into three categoriest A) Control badges - greater than 5 miles from the plant (13 badges) B) Offsite badges - from owner-controlled fence to 5 miles from the plant (25 badges) C) Onsite badges - within owner-controlled fence (3 badges) O , l.y

The control badge results are averaged for each quarter to deterairo a background dose reading for the environment. This reading can then be subtracted from each onsite or of f site badge reading to determine the potential dose contribution f rom 1ACBWR. The following is a listing of the highest quarter location and also the quarterly averages. !!IGi!EST TLD READING (minus control badge average value) IST OTR 2ND OTR 3RD OTR 4Til OTR Onsite (mrem /atr) 2.5 1 4.2 0.7 1 0.7 0 0 Onsite location

1 i 4 2.2 AIR PARTICULATE The gross beta-gamma activity concentrations from air particulate filters are shown in Table 10. Composite air particulate isotopic analyses are found in Table 11. Comparison between the control station at La Crosse and the six stations near LACBWR indicate that there was no significant plant attributable airborne particulate. 2.3 RIVER WATER The river water gamma isotopic analyses are shown in Table 12. The results indicate that there is insignificant plant attributable radio-nuclides in river water. The river water samples taken above, at and below the plant dis'.harge point generally exhibited similar activity patterns during 1990. () 2.4 SE.'4ENT SAMPLES Sediment samples were collected above, at, &nd below the,lant outfall. These samples were gamma analyzed and these results appear on Table 13. They indicated that small amounts of plant attributed radionuclides have accumulated in river sediments near the outfall. l.

2.5 HILK SAMPLES Milk samples were collected on a biweekly basis during the grazing season (May through September) from three dairy farms in the vicinity of LACBWR and gamma analyzed. These samples are listed in Tablo 14. There has been no significant accumulation of plant attributed radionuclides in milk in the vicinity of LACBWR. 2.6 FISH Fish samples were collected quarterly above and below the plant discharge.
