1.0 INTRODUCTION
The La Crosse Boiling Water React.or, also known as Genoa
- 2, is located on the east bank of the Mississippi 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 50 MW(e) 165 Mw(th).
The reactor is owned and operated 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 power tests in August 1969, the plant has been operating between 60% and 100% of full power, with the exception of plant shutdowns for maintenance and repair.
During 1980 the plant factor had been 69%.
During the first half of 1981, the plant factor has been approximately 53%.
The monitoring program at the LACBWR facility includes moni-toring 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 rad-l iation.
The penetrating radiation is measured by thermolumi-nescent dosimetry (TLD).
During the second quarter of 1981, additional environmental TLD monitoring stations had been established at distances from the plant ranging from 1 to 23 miles.
The program is conducted to the extent necessary to ensure that releases of radioactivity to the environment do not result in radiation doses to the surrounding population, which exceed l
l established radiation protection regulations.

This monitoring report includes the period from January 1, 1981 to July 1, 1981.
The report includes a description of the environmental samples collected, analytical methods and i
the results from these analyses.
A map of the general vicinity surrounding LACBWR is provided for the reader so that he may determine the spatial relation-l ship of the plant to the surrounding area.
The map includes the plant boundary, roads, other generating plants, relation l
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 environ-mental sampling stations for surface air, rain water, milk, vegetation and TLD's.
This map will allow the reader to I
determine the spatial relationship of the plant to the 3
surrounding sampling stations.
1 Figure 3 is a map that pinpoints the location of the additional environmental TLD monitoring stations established during the second quarter of 1981.
This map will allow the reader to approximately determine the spatial relationships of the plant to the additional surrounding TLD monitoring stations.

2.0 SAMPLE COLLECTION The sampling frequency of the various environmental samples and the analyses performed on these samples are shown in Table I.
The number of various samples collected and analyzed during the first half of 1981 appear in Table II.
The penetrating radiation dose is measured by thermoluminescent dosimeters consisting of five lithium fluoride (LiF) chips.
The TLD's are located in the vicinity of the plant on poles, trees or 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 30 1pm with Gelman Air Samplers.
The air filter consists of a glass fiber filter with an associated pore size of approximately 0.45 p an activated charcoal CESCO type cartridge for iodine collection.
The particulate filters are analyzed for gross alpha and beta activity with a low background. internal proportional counter 131 and the activated charcoal filter for I is analyzed with a l
low background Ge (Li)-MCA system in the LACBWR Radio-Environmental Laboratory.
(
River and rain water samples are collected monthly.
River water samples above and below the plant site are collected and t
gross beta activity determined on a one-liter sample.
l A four-liter milk sample is collected from three farms in the vicinity of the plant on a biweekly basis during the 1 l l
131 grazing season.
The milk samples are then analyzed for 7
90 and Sr, with a minimum sensitivity of 1 pCi/ liter.
These samples are analyzed by the Radio-analytical Chemistry Depart-ment at the University of Wisconsin at La Crosse.
Vegetation samples are collected twice per year from nearby farms and an isotopic analysis is performed by Ge(Li) - MCA gamma spectroscopy.
Sediment samples are collected twice a year below the plant and an isotopic analysis is performed by Ge(Li) - MCA gamma spectroscopy.
Fish samples are purchased on a monthly basis from commercial fisherman.
The fish are from Pool #8 above the plant, and Pool #9 below the plant.
These samples are analyzed by Ge (Li)-
MCA gamma spectroscopy.

3.0 RESULTS OF Tile JANUARY-JUNE 1981 RADIO-ENVIRONMENTAL MONITORING SURVEY 3.1 PENETRATING RADIATION The thermolumincescent dosimeters are changed on a quarterly basis and analyzed for dose by the Eberline Instrument Corp-oration.
The results of the analysis are shown on Table III.
The highest measured on-site dose from LACBWR operations was to the adjacent coal-fired power plant, Genoa #3, (Environ-mental Station #10).
This dose was approximately 19.0 mrem /
lst quarter and 13.0 mrem /2nd quarter.
The average dose per quarter attributable to LACBWR operations at all off-site environmental stations during the year was <1 mrem / quarter.
The maximum off-site dose at any location was 4 mrem / quarter and occurred at Station 14 (2nd quarter).
Station 15 (Lock and Dam No. 8) had a TLD reading of 38.1 mrem during the 2nd quarter.
This number appears to be an anomoly and may be due to annealling error.
This reading is being investigated by Eberline I. C.
3.2 AIR PARTICULATE The gross beta-gamma activity concentrations from air parti-culate filters are shown in Table IV.
The air particulate beta activity concentrations ranged from less than 0.035 pCi/m to 0.588 pCi/m.
The semi-annual average concentra-3 tion at the control location was 0.256 pCi/m while for the other six stations, the annual average concentration was 3
0.267 pCi/m.
Seasonal variations in concentrations are similar at near site locations and the control station.
3.3 PRECIPITATION AND RIVER SAMPLES The results of the gross beta activity measurements for rive water and precipitation are shown in Tables V and VI, respec-tively.
The river water samples taken above and below the plant generally exhibit similar patterns in activity over the year.
Downstream samples were two to seven times the up-stream concentrations during February 1981.
The highest measured concentrations of 15.51 pCi/1 occurred in February 1
at the boat launch on DPC property immediately south of the G-3 plant.
The gross beta concentrations in precipitation samples taken during January to June 1981 ranged from 14.34 1.42 pCi/l to 166.26 6.74 pCi/l (Pedretti Parm).
3.4 SEDIMENT SAMPLES Sediment samples were not collected during the period January 1 to June 30, 1981.
3.5 MILK SAMPLES Milk samples were collected on a biweekly basis during the grazing season (May through September) from three dairy farms 90 in the vicinity of LACBWR and analyzed for I.and Sr with 90 a detection limit of 1 pCi/1.
The average Sr concentration in milk was 6.24 pCi/1.
These samples are listed in Table VII.
3.6 ACTIVIATED CHARCOAL CARTRIDGES 131 The analysis of the activated charcoal cartridges for 7
was performed by counting each cartridge collected during a _-. ~ _., _ -. _ _ _.. _ __. _ _ _ _ _ _ __
'/
1-week period and averaging the measured concentrations.
131 Weekly average I concentrations for the seven measurement locations are shown in Table VIII.
Average concentrations are 2.01 E-15 pCi/m.
3.7 VEGETATION Vegetation samples were not collected during the period January 2 to June 30, 1981.
3.8 FISH Fish samples were collected monthly above and below the plant discharge.
The results of gamma spectral analysis of fish samples appear in Table IX.
There has been no significant accumulation of radionuclides of plant origin in fish in the plant vicinity.
4.0 CONCLUSION
S The maximum off-site dose as determined by TLD was 4 mrem /
quarter.
The average off-site dose as determined by TLD was less than 1 mrem / quarter.
The dose to the general populations during the first half of 1981 was well within current regulations.
The concentration of radioisotopes found in the environmental samples collected during the first half of 1981 were found to be well within current regulations...
