i 1979 January - June Supplemental Information to the Semiannual Effluent and Waste Disposal Report Facility: La Crosse Boiling Water Reactor (LACBWR) Licensee: Dairyland Power Cooperative, Docket No. 50-409

1) Regulatory Limits LACBWR Technical Specifications for airborne effluents are limited to the following " Curie Release Rates," for various plant conditions, based on the MPC of the mixture (in pCi/

cc) being discharged: Stack Blowers Maximum Yearly Average Operating Release Rato Release Rate Particulates and 1 2.4 x 103 x FPC 2.4 x 102 x FPC Halogens with Half-lives Greater than 8 Days 2 5.1 x 103 x MPC 5.1 x 102 x bPC All Other Radio-1 1.6 x 106 x FPC 1.6 x 105 x FPC active Isotopes (Gases) 2 3.4 x 106 x MPC 3.4 x 105 x MPC The values expressed in Table II, Airborne Releases, Item 9, " Allowable Total Releases," show the allowable yearly aver-age releases based on actual plant conditions, i.e., one or two blower operation whichever had occurred during the month, and any recalibrations which had been performed on the off-gas monitor. LACBWR Technical Specification limits for liquid effluents are limited to 1 MPC values after dilution averaged over the year. The values reported in Table I, Liquid Releases, Items 1b, c, and d; 2b and c; 3b and c; and 4b are based on dilu-tion with plant site circulating water flow only. No credit is taken for further dilution in the mixing zone of the Mis-sissippi River, shown as Item 5, Average Stream Flow.

2) Maximum Permissible Concentration (MPC)

The MPC used to calculate permissible release rates are ob-tained from 10 CFR 20, Appendix D, Tables I and II. In addi-tion, the following values are used. j}Q Q8} --

i I 3 Tritium in Water 3 x 10 pCi/ml. = I Tritium in Air 2 x 10 pCi/cc. =

3) Average Energy The release rate limits for LACBWR are not based on average energy.

4) Measurement Methods Liquid effluent measurements for gross radioactivity are performed by gamma analysis on a Ge-Li detector for each tank discharged.

A composite sample is created by collect-I ing representative amounts from each tank batch discharged and it is analyzed monthly for Tritium, Strontium 89 and 90, and Gross alpha activity. In addition, each tank is analyzed I fo. alpha concentration and the higher of these two analysis is the basis for the values reported in Table I, line 4. Airborne gaseous effluents are determined by gamma analysis I on a Ge-Li detector of samples from the various fl( w paths. TF, analysis includes a determination of gaseous halogen es. cent. Airborne particulate and particulate halogen releases are determined by gamma analysis on a Go-Li detector of weekly samples of stack discharges on glass fiber filter paper and charcoal cartridge absorbants.

5) Batch Releases All airborne effluent releases at LACBWR are Continuous-Elevated Release point type releases.

All liquid effluent releases at LACBWR are Batch Releases and the requested information is included in Table I, Item 8.

6) Abnormal Releases No abnormal releases occurred during this reporting period at LACBWR.

7) Estimated Total Error The values reported in Table I, II, and III contain the fol-lowing estimated errors:

Counting Error + 1 Standard Deviation Sampling Volume Error 5%. 1138 082 _

8) Allowable Total Tritium Releases (line 9d in 1978 report and previous reports) were conservatively low by a value of 5000 to 10000.

Therefore, the values reported in (line 7d) percent of applicable limit for tritium are also con-servatively high by the same 5000 to 10000 factor in 1978 and prior reports. M 1138 083 ' ~

N -- 1.0 Introduction The La Crosse Boiling Water Reactor, also known as Geroa #2, is located on the east bank of the Mis-sissiE'i River at Genoa, Vernon County, Wisconsin. The plant was designed and constructed by the Allis-Chalmers Manufacturing Company. It was completed in 1967 and has a generation capacity of 52 Mw(e) 165 MW (th). The reactor is owned and operated by Dairy-land Power Cooperative (DPC). The reactor went critical in July 1967, and first contributed electricity to DPC's system in April 1968. After completing full power tests in August 1969, the plant has been operating between 60% and 100% of full power, with the exception of plant shutdowns for main-tenance and repair. During the first six months of 1979, the plart factor wcs 29%. The monitoring program at the LACBWR facility includes monitoring of liquid and gaseous releases from the plant as well as environmental samples of surface air, river water, rain water, sediment, milk, fish, vegetation and penetrating radiation. The pene-trating radiation is measured by thermoluminescent dosi-metry (TLD). The program is conducted to the extent necessary to ensure that releases of radioactivity to the enviran-mant do not result in radiation doses to the surrounding population, which exceed established radiation protec-tion regulations. This monitoring report includes the period from January 1, 1979 to June 30, 1979. The report includes a description of the environmental samples collected, analytical methods and the results from these analyses. A map of the general vicinity surrounding LACBWR is provided tor the reader ao that he may determin.; the spatial relaticnship of the plant to the surrounding "he map includes the plant boundary, roads, area. other generating I lants, relation of the plant site to the nearest local community as shown in Figure 1. Figure 2 is a map that pinpoints the location of the environmental sampling stations ",r surface air rain water, milk, vegetation and TLD'<. This map will allow the reader to determine the spatial rela'ionship of the plant to the surrounding sampling stations. _ _ _ - _

2.0 Sample Collection The 'ampling frequency of the various environmental samples and the analyses performed on these samples are shown in Table IV. The number of various samples col-lected and analyzed from January to June of 1979 appear in Table V. The penetrating radiation dose is measured by thermo-luminescent dosimeters consisting of five lithium fluoride (LiF) chips. The TLD's are located in the vicinity of the plant on poles, trees and adjacent to air samplers. The TLD's are collected, shipped and then analyzed by the Eberline Instrument Company. Air samples 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 1 cfm with Gelman Air Samplers. The air filter consists of two filters - one a membrane filter with an associated pore size of 0.45p and an activated charcaal filter for iodine collection. The particulate filters are analyzed for gross beta gamma activity and the activated charcoal 133 filters for I. River and rain water samples are collected monthly. River water samples above and below the plant site are col-lected and gross beta gamma activity determined on a one-liter sample. A four-liter milk sample is collected from three farms in the vicir.ity of the plant on a biweekly basis during the grazing season. The milk samples are then analyzed for 131 'C I and Sr, with a minimum sensitivity of 1 cCi/ liter. Vegetation samples are collected twice per year from nearby farms and isotopic analysis performed by gamma spectroscopy. Sediment samples are collected twice a year below the plant and an isotopic analysis performed. Fish samples are purchased on a monthly basis from conmercial fishermen. The fish are from Pool #8 above the plant, and Pool #9 below the plant. 1138 087

3.0 Results of the Environmental Monitoring Survey for the first half of 1979. 3.1 Penetrating Radiation The thermoluminescent dosimeters are changed on a quarterly basis and analyzed for dose by the Eberline Instrument Corporation. The results of the analysis are shown on Table VI. The highest measured on-site dose from LACBWR operations was to the adjacent coal-fired power plant, Genoa #3 (Environmental Station #10). This dose was approximately 25 mrem / quarter. The aver-age dose per quarter attributable to LACBWR operations at all off-site environmental stations during the first six months was <1 mrem / quarter. A maximum of 3 mrem / quarter at Station 17 was recorded. 3.2 Air Particulate The gross Beta-Gamma activity from the air partic-ulate filters are shown in Table VII. The air partic-ulate Beta-Gamma activity ranged from 0.018 - 0.134 pCi/M3 during the year. This range is within the range of air activity at the control station and shows the typical seasonal variations. 3.3 Precipitation and River Samples The results of the gross Beta-Gamma activities from precipitation and river water are shown in Tables VIII, IX and X respectively. The river water samples taken above and below the plant indicate no significant difference. The precipitation samples taken in the vicinity of LACBUR ranged from 4 - 60 pCi/1. 3.4 Sediment Samples No sediment samples were collected during the first six months of 1979. 3.5 Milk Samples Milk samples were collected on a bi-weekly basis during the grazing season from three dairy farms in the vicinity of LACBWR. The samples were analyzed for 332 I and Sr, with a detection limit of 1 pCi/1. The re-sults shown in Table XI indicate the milk samples were below the minimum detectable activity for I. The 231 average content of ' Sr in the samples was 4.3 pCi/1. J 1138 090 __

R 3.6 Activated Charcoal c'ilter The results from the activated charcoal filters 3'3 for I was performed by averaging all of the char-coal filter analysis results collected during a one-week period. The results shown in Table XII indicate all samples were well within established guidelines. 3.7 Vegetation No vegetation samples were collected during the first six months of 1979. 3.8 Fish Fish samples were collected from the vicinity of the plant; the results of the gamma spectrosc-;py analy-sis are shown in Table XIV. Calibration of the system during the period changed the minimum detectable activities for some isotopes. The results indicate that there has been no significant accumulation of radioisotopes in fish in the vicinity of the plant. M 1138 09i _
