O INTRODUCTION; 4

The La Crosse Boiling Water Reactor (LACBWR), also known as Genoa Station No. 2, is locatedon the east bank ofthe MississippiRiver near Genoa Vernon County, Wisconsin. The plant was designed and constructed by the Allis-Chalmers Manufacturing Company. It was completedin 1967 and hada generation capacity of 50 MW(165 MW,). The reactor is owned l by DairylandPower Cooperative (DPC).

l

)

The reactor went critical in July 1967 andfirst contributed electricity to DPC's . system in April 1968. After completingfullpower tests in August 1969, the plant operated between 60%

3 (V and 100%fidipower, with the exception ofplant shutdownsfor maintenance and repair.

In April of1987 plant operation was ceased 7he reactor is presently defueledand in a SAFSIOR mode. In August of1987 apossession-only license was received.

In accordance with LACBWR Technical Specifications 6.5.1.1.d andin compliance with 10 CFR 50.36a(a)(2), this document is the Radioactive Effluent Reportfor the periodJanuary I through December 31,1998.

I 1.0 REGULATORY LIMITS

a. - Gaseous Ellluent Release Lirnits:

LACBWR's stack efiluent release limitations for gaseous effluent aicases of radioactive materiallimits the release rate of the sum of the individual radionuclides, so that the dose rates to members of the public beyond the EfIluent 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 and particulates with half-lives greater than 8 days as per the requirements of the Offsite Dose Calculation Manual (ODCM).

O Also, in accordance with 10 CFR 50, Appendix I, the ODCM limitations for gaseous efiluent radioactive material limit the air dose to a member of the public from noble gases in areas beyond the Efiluent Release Boundary to less than 5 mrad gamma and 10 mrad beta per calendar quarter, and less than 10 mrad gamma and 20 mrad beta per  :

l calendar year. The dose limits from H-3 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 l

year to any organ.

l l

Cumulative dose contributions from gaseous efiluent releases are determined in i accordance with the LACBWR Offsite Dose Calculations Manual.

LACBWR's liquid emuent release limitations for liquid emuent releases are those ]

l concentrations specified in 10 CFR 20 Appendix B, Table 2, Column 2. For alpha l

. emitting radionuclides, the concentration is limited to a total activity concentration of I

4.9 E-9 pCi/ml, based upon an actual alpha emitting radionaclide analysis performed on a representative water sample. The values reported in tables 2A and 2B, Liquid Emuents, l are based on dilution with the combination of LACBWR and Genoa Station No. 3 l condenser ccoling water flow prior to discharge to the Mississippi River. No credit is taken for further dilution in the mixing zone of the Mississippi River.

!: Also, in accordance with 10 CFR 50, Appendix I, the dose commitment to a member of the public from radioactive materials released in liquid emuents to areas l

beyond the Emuent Release Boundary are limited to less than 1.5 mrem whole body and l

i 5.0 mrem organ dose per calendar quarter, and less than 3.0 mrem whole body and l i

'4.0 ANALYTICAL METHODS i

a.- Liquid Effluents i Liquid effluent measurements for gross radioactivity are performed by HPGe gamma isotopic analysis of a representative sample from each tank discharged. In addition, each batch discharged tank is analyzed for alpha and tritium activity

'G . concentration. A composite sample is created by collecting representative aliquots from l

' - Q I each tank batch discharged during a calendar quarter. This composite is analyzed for  !

' Iron-55 and Strontium-90 by a contractor on a quarterly basis.

b. Airborne Particulates Airbome particulate releases are determined by HPGe gamma isotopic anal:' sis.

This analysis is performed by analyzing a glass fiber filter paper taken from the stack monitor which continuously isokinetically samples and monitors the stack efiluent. This l

- filter is changed and analyzed on an approximate weekly basis and analyzed within 7 days after removal. This filter is also analyzed for alpha activity. .A quarterly composita of these filters is sent to a contractor for Sr-90 analysis.

Since the plant shutdown in April 1987, the I-131/I-133 have decayed completely f to stable elements. Amendment 66 to the LACBWR Tecimical Specifications, deleted the requirement for monitoring for iodine.

d. Fission andActivation Gases The concentration of radioactivity (pCi/cc) in gaseous releases from the stack is continuously monitored by two in line stack monitors. These gas concentrations ( Ci/cc) are corrected for pressure loss in the sampling system and averaged by the monitors microprocessor. The results are used along with the stack flow rate to obtain the daily gaseous release from the plant. Since the plant shutdown in April 1987, gaseous releases have been immeasurable. All fission gases except Kr-85 have decayed to stable elements.

. ,O c. Tritium v

Tritium releases are determined by taking a grab sample of the stack atmosphere at the efiluent of the stack monitor. Tritium, as tritiated water, is removed from the sample stream by condensation, using a cold trap. The condensed water vapor is then distilled and the distillate is analyzed for H-3 concentration ( Ci/cc), by internal liquid scintillation spectrophotometry and the results are expressed in terms of tritium release rates. The i

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 l

7 days.

l rs l Q INTRODUCTION:

The Radiological Divironmental Monitoring (REM) Program is conducted to comply with the requirements of the ODCMandin accordance with 10 CFR 50 Appendix I. The REM Program provides measurements ofradiation and ofradioactive materials in those exposure pathways andfor those radionuclides which couldpotentially lead to radiation doses to Members of the Public resultingfrom plant effluents. Environmental samples at e taken within the surrounding areas of the plant and in selected control or background locations. \

l The monitoringprogram at the IA CB WRfacility includes monitoring ofliquid and gaseous releasesfrom the plant, as well as environmental samples ofsurface air, river water, i

river sediment, milk, fish, andpenetrating radiation.

The REMprogram theory supplements the Radioactive Effluent analyses by venfying that the measurable concentrations of radioactive materials and levels ofradiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathwayr using the methodology of the Offsite Dose Calcidation i

Manual (ODCM).

2.0 RESULTS OF THE 1998 RADIO-ENVIRONMENTAL MONITORING SURVEYS During 1998, activity levels in the local environment were normal, indicating no significant plant attributed radioactivity.

2.1 PENETRATING RADIATION The environmental penetrating radiation dose is measured by thermoluminescent dosimeters consisting of four lithium fluoride (LiF) chips. These TLD's are changed on a quarterly basis and are sent to an outside contractor for reading. The TLD results for p 1998 are shown on Table 9.

RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT - (cont'd) rm 2.2 AIR PARTICULATE Air samples are collected continuously from various sites (see Table 6) around LACBWR. An air sampler is also located 18 miles nonh of the plant in La Crosse, Wisconsin, to act as a control station.

Paniculate air samples are collected at the rate of approximately 30-601pm with a Gelman Air Sampler. The air filter consists of a glass fiber filter with an associated pore size of approximately 0.45 pm. The particulate filters are analyzed weeldy for gross beta activity with an internal proportional counter, and the monthly particulate composites are gamma analyzed for individual isotopic concentration.

TABLE 10 This table shows the weekly gross beta gamma activity concentration from the air particulate filters.

C

\ TABLE 11 This table shows the composite air paniculate isotopic analysis.

Comparison between the control station at La Crosse and the other stations near LACBWR indicate that there was no significant plant attributable airborne paniculate activity.

2.3 RIVER WATER River water is collected monthly. River water sampics above, at, and below the plant site are collected and are gamma analyzed for isotopic concentration. The river water gamma isotopic analysis results are shown in Table 12. The results indicate that there is insignificant plant-attributable radionuclides in the river water.
