,. e a f- 4 INTRODUCTION: ,

u -

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 construetad 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 owneu by Dairyland r

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% full power, with the

- exception of plant shutdowns for maintenance and repair.

In April of 1987 plant operation was ceased. The reactor is presently defueled and work is progressing to place the plant into a SAFSTOR mode. .In August ofl1987 a possession-only license was received.

l 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 l Effluent Report for the period January 1 through June 30, 1989.

1. REGULATORY LIMITS

a. Gaseous Effluent Release Limits:

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 and particulate 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 Releas2 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 calendar year. The dose limits from H-3, I-131/133 and particulate 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.

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

RER 2 l i

<______ -- - -- )

b. Liquid Effluent Release Limits:

LACBWR'o Technical Specifications limits for liquid effluent releases are limited to those concentrations cf individual radionuclides sur.h that the diluted discharge does not exceed 1 MPC in a 168-hour week averaged over tu, calendar year. For dissolved or entrained noble gases, the concentration is limited to a total activity concentration of 2 x 10-* pCi/ml. For alpha emitting radionuclides, the concentration is limited ta a total activity concentration of 4.9 x 10 pCi/ml, based upon an actual alpha emitting radionuclides 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 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 effluents to areas beyond the Effluent Release Boundary are limited to less than 1.5 mrem whole body and 5.0 mrem organ dose per 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 a:cordance with the LACBWR Offsite Dose Calculation Manual.

RER 3

c. Solid Radioactive Waste .,

{

/

All solid radioactive wastes are handled in accordance witt 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 B, Tables I and II. In addition, the following values are used:

Tritium in Water = 3 x 10'8 pCi/ml.

Tritium in Air = 2 x 10-7 pCi/cc.

3. AVERAGE ENERGY The release rate limits for LACBWR are not based on average energy.

4. ANALYTICAL METHODS

a. Liquid Effluents Liquid effluent measurements for gross radioactivity are performed by Ge-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 each tank batch discharged, and is analyzed monthly for Tritium, and quarterly for Iron-55 and Strontium 89 & 90. The iron and radiostrontium are analyzed by a l

contractor. In addition, each batch discharged tank is analyzed for alpha activity concentration.

b. Airborne Particulate Airborne particulate releases are determined by Ge-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 and analyzed on an approximate weekly basis and analyzed within 7 days after removal. This filter is also analyzed for alpha activity. A quarterly composite of these filters is sent to a contractor for Sr 89 and 90 analysis.

l.:

c. Radioiodines Radioiodine releases are determined by Ge-Li gamma analysis of a TEDA impregnated activated charcoal cartridge taken from the stack monitor which continuously isokinetically samples and monitors the stack effluent. This charcoal cartridge is changed approximately weekly and analyzed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> 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 !

shutdown in April 1987,' gaseous releases have been immeasurable. All fission gases except Kr-85 have decayed completely to stable elements.

f;

e. .

Tritium Tritium releases are determined by taking a grab sample of the stack atmosphere at the effluent of the stack monitor. Tritium, as' l

tritiated water, is removed from the sample stream by condensation, using a cold trap containing an organic compo:.nd 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.

5. BATCH RELEASES

a. Airborne All airborne effluent releases at LACBWR are from a single Continuous-Elevated Release Point.

b. Liquid All liquid effluent releases at LACBWR are batch releases. This is summarized as follows:

a. Gaseous Effluent Releases The maximum quarterly offsite gamma dose due to noble gases was 0.00 mrad. The cusalative 1989 annual offsite Samma dose due to noble gases was 0.00 mrad.

The maximum' quarterly offsite beta dose due to noble gases was 0.00 mrad. The cumulative 1989 annual offsite beta dose due to noble gases was 0.00 mrad.

The maximum quarterly offsite dose to any organ fram the release of I-131, I-133, H-3 and all radionuclides in particulate form with half-lives greater than 8 days was approximately 1.95E-2 mrem. The cumulative 1989 annual maximum organ dose from these radionuclides was approximately 2.10E-2 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 sced to calculate these offsite dose values.

b. Liquid Effluent Releases The maximum quarterly organ dose from liquid releases was approximately 0.02 mrem. The maximum cumulative 1989 annual organ dose was approximately

• mrem. The maximum quarterly whole body dose for liquid releases was approximately 1.34E-2 mrem, and the cumulative 1989 annual whole body dose was approximately

• mrem.

c. Conclusion All calculated offsite doses were below Technical Specification limits.
