1.0 INTRODUCTION

The Kewaunee Nuclear Power Plant is a 535 megawatt pressurized water reactor located on the Wisconsin shore of Lake Michigan in Kewaunee County. The Plant became critical on March 7, 1974.

Initial power generation was achieved on April 8, 1974, and the Plant was declared commercial on June 16, 1974. This report summarizes the environmental operation data collected during the period January - December 2001.

Nuclear Management Company, LLC, an operating company for the Kewaunee Nuclear Power Plant, assumes the responsibility for the environmental program at the Plant and any questions relating to this subject should be directed to Mr. Stanley F. Baker, Manager of Radiation Protection, at (920) 388-8103.

SUMMARY

Ii Results of sample analyses during the period January - December 2001 are summarized in Table 4.5. Radionuclide concentrations measured at indicator locations are compared with levels measured at control locations and in preoperational studies. The comparisons indicate background-level radioactivities in all samples collected.

3.0 RADIOLOGICAL SURVEILLANCE PROGRAM Following is a description of the Radiological Surveillance Program and its execution.

3.1 Methodology The sampling locations are shown in Figure 4-1. Table 4.1 describes the locations, lists for each direction and distance from the reactor, and indicates which are indicators and which are control locations.

The sampling program monitors the air, terrestrial, and aquatic environments. The types of samples collected at each location and the frequency of collections are presented in Table 4.2, using sample codes defined in Table 4.3. The collections and analyses that comprise the program are described below. Finally, the execution of the program in the current reporting year is discussed.

3.1.1 The Air Program Airborne Particulates The airborne particulate samples are collected on 47 mm diameter glass fiber filters at a volumetric rate of approximately one cubic foot per minute. The filters are collected weekly from six locations (K if, K-2, K-7, K-8, K-16 and K-31), and dispatched by mail to Environmental, Inc. for radiometric analysis. The material on the filter is counted for gross beta activity approximately 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months or later after collection to allow for decay of naturally-occurring short-lived radionuclides.

Quarterly composites from each sampling location are analyzed for gamma-emitting isotopes by germanium detector.

Airborne Iodine Charcoal filters are located at locations K-if, K-2, K-7, K-8, K-16 and K-31. The filters are changed bi-weekly and analyzed for iodine-1 31 immediately after arrival at the laboratory.

Ambient Gamma Radiation - TLDs The integrated gamma-ray background is measured at six sampling locations (K-if, K-2, K-7, K-8, K-15 and K-1 6), at four milk sampling locations (K-3, K-5, K-25 and K-35), and four additional sites (K 17, located 4.25 miles west of the plant; K-27, located 1.5 miles northwest of the plant; K-30, located 1.0 miles north of the plant and K-31, located 6.25 miles north-northwest of the plant) by thermoluminescent dosimetry (TLDs). Two TLD cards, each having four main readout areas containing CaSO4:Dy phosphor, are placed at each location (eight TLDs at each location). One card is exchanged quarterly, the other card is exchanged annually and read only on an emergency basis.

Precipitation Monthly composites of precipitation samples collected at K-1i1 are analyzed for tritium activity and counted using a liquid scintillation method.

Ii 3.1.2 The Terrestrial Program II Milk 1 Milk is collected semimonthly from May through October, and monthly during the rest of the year from three herds that graze within four miles of the reactor site (K-5, K-25 and K-34), from two herds that graze between four and ten miles from the reactor site (K-3 and K-35), and from a dairy in Green 1

Bay (K-28). The samples are analyzed for iodine-131, strontium-89 and -90, cesium-137, barium lanthanum-140, potassium-40, calcium and stable potassium.

Well Water One gallon of water is collected quarterly from four off-site wells located at K-10, K-11, K-12 and K-13 and from two on-site wells located at K-lg and K-ih.

Ii Gamma spectroscopic analyses and gross beta on the total residue are performed for each water sample. The concentration of potassium-40 is calculated from total potassium, which is determined by flame photometry on all samples.

Additionally, samples of water from two on-site wells (K-i g and K-i h) are analyzed for gross alpha.

Water from the on-site well (K-1g) is also analyzed for tritium, strontium-89 and strontium-90.

Domestic Meat Domestic meat samples are obtained annually (in the third quarter) at locations K-24, K-27 (if available), K-29, K-32 and K-34. The flesh is separated from the bones and analyzed for gross alpha, gross beta and gamma emitting isotopes.

Eggqs Eggs are collected quarterly from locations K-24, K-27 (if available) and K-32. Samples are analyzed for gross beta, strontium-89 and -90, and gamma-emitting isotopes.

Vegetables Vegetable samples (6 varieties) are collected at locations K-17 and K-26, and two varieties of grain, if available, at location K-23. The samples are analyzed for gross beta, strontium-89 and -90, and gamma emitting isotopes.

Grass and Cattle Feed Grass is collected during the second, third and fourth quarters from two on-site locations (K-lb and K-if) and from five dairy farms (K-3, K-5, K-25, K-34 and K-35). The samples are analyzed for gross beta, strontium-89 and -90, and gamma emitting isotopes. During the first quarter, cattle feed is collected from the same five dairy farms and the same analyses are performed.

Soil Soil samples are collected twice a year on-site at K-if and from the five dairy farms (K-3, K-5, K-25, K-34 and K-35). The samples are analyzed for gross alpha, gross beta, strontium-89, strontium-90 and gamma emitting isotopes.

3.1.3 The Aquatic Proqram Surface Water One-gallon water samples are taken monthly from three locations on Lake Michigan: 1) at the point where the condenser water is discharged into Lake Michigan (K-id); 2) Two Creeks Park (K-14) located 2.5 miles south of the reactor site; and 3) at the main pumping station located approximately equidistant from Kewaunee and Green Bay, which pumps water from the Rostok water intake (K-9) located 11.5 miles north of the reactor site. Both raw and tap water are collected at K-9. One-gallon water samples are taken monthly from three creeks that pass through the site (K-i a, K-1 b, and K-i e).

Samples from North and Middle Creeks (K-ia, K-lb) are collected near the mouth of each creek.

Samples from the South Creek (K-le) are collected about ten feet downstream from the point where the outflow from the two drain pipes meet. Additionally, the drainage pond (K-lk), located approximately 0.6 miles southwest of the plant, is included in the sampling program. Water samples at K-14 are collected and analyzed in duplicate.

The water is analyzed for gamma emitting isotopes, gross beta activity in total residue, dissolved solids and suspended solids, and potassium-40. The concentration of potassium-40 is calculated from total potassium, which is determined by flame photometry. In addition, quarterly composites of the monthly grab samples are analyzed for tritium, strontium-89 and strontium-90.

Fish Fish samples are collected during the second, third and fourth quarters at location K-id. The flesh is separated from the bones, gamma scanned and analyzed for gross beta activity. Ashed bone samples are analyzed for gross beta, strontium-89 and strontium-90 activities.

Slime Slime samples are collected during the second and third quarters from three Lake Michigan locations (K-id, K-9 and K-14), from three creek locations (K-la, K-lb and K-le) and from the drainage pond (K-i k), ifavailable. The samples are analyzed for gross beta activity. If the quantity is sufficient, they are also gamma scanned and analyzed for strontium-89 and strontium-90 activities.

Bottom Sediment Bottom sediments are collected in May and November from five locations (K-ic, K-id, K-lj, K-9 and K-14). The samples are analyzed for gross beta, strontium-89, strontium-90 and gamma emitting isotopes. It is known that the measured radioactivity per unit mass of sediment increases with decreasing particle size, and the sampling procedure is designed to assure collection of very fine particles.

3.1.4 Program Execution II Program execution is summarized in Table 4.4. The program was executed for the year 2001 as described in the preceding sections, with the following exceptions:

No precipitation was available for collection in August.

Milk, soil and grass was not available from location K-35 (Ducat Farm) after September. The farm was .[

dropped from the sampling program.

Well water was missed from location K-25 for the first quarter of 2001. 1 Surface water samples were not available for the month of January at locations K-la and K-lk. The creek and pond were both frozen.

Surface water was not available for the month of February at locations K-lk, K-14a and K-14b, due to freezing conditions.

Surface water was not available for the month of March at location K-1 K. The pond was frozen. Ii 3.1.5 Program Modifications One farm (Ducat, K-35) was dropped from the program in September of 2001. A replacement dairy will be made for 2002.

3.2 Results and Discussion The results for the reporting period January to December 2001 are presented in summary form in Table 4.5. For each type of analysis, of each sampled medium, this table shows the annual mean and range for all indicator and control locations. The location with the highest annual mean and the results for this location are also given.

The discussion of the results has been divided into three broad categories: the air, terrestrial, and aquatic environments. Within each category, samples will be discussed in the order listed in Table 4.4.

Any discussion of previous environmental data for the Kewaunee Nuclear Power Plant refers to data collected by Environmental Inc., Midwest Laboratory.

The tabulated results of all measurements made in 2001 are not included in this section, although references to these results will be made in the discussion. A complete tabulation of results is contained in Part II of the 2001 annual report on the Radiological Monitoring Program for the Kewaunee Nuclear Power Plant.

3.2.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no atmospheric nuclear tests or accidents reported in 2001. The last reported test was conducted by the People's Republic of China on October 16, 1980.

3.2.2 The Air Environment Airborne Particulates The annual gross beta concentration in air particulates measured 0.024 pCi/m 3 at the indicator locations and 0.023 pCi/m 3 at the controls. The averages were almost identical to the means observed from 1990 (and prior to) through 2000. Results are tabulated below.

I1 Airborne Particulates (continued) 11 Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation (Arnold and AI-Salih, 1955), was detected in all samples. All other gamma-emitting isotopes were below their respective LLD limits.

Airborne Iodine L Bi-monthly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.030 pCi/m 3 at all locations. There is no indication of an effect of the plant operation on the local air environment.

Ambient Gamma Radiation - TLDs Ambient gamma radiation was monitored by TLDs at fourteen locations: seven indicator and seven control.

Quarterly TLDs at indicator locations measured a mean dose equivalent of (18.6 mR/91 days), in agreement with the mean at the control locations of (18.3 mR/91 days), and were similar to the means I-I obtained in 1990 (and prior to) through 2000. The results are tabulated below. No plant effect on ambient gamma radiation was indicated These values are slightly lower than the United States average value of 19.5 mR/91 days due to natural background radiation (National Council on Radiation Protection and Measurements, 1975). The highest annual mean was 21.0 mR/91 days, measured at the indicator location K-7.

3.2.3 The Terrestrial Environment Milk Of the 103 analyses for iodine-1 31 in milk, all were below the LLD level of 0.5 pCi/L.

Strontium-89 concentrations measured below an LLD level of 2.0 pCi/L in all samples. Low levels of strontium-90 were found in 68 out of 69 samples tested. Mean values were identical for indicator and control locations (1.5 pCi/L) and are similar to or less than averages seen from 1989 through 2000.

Barium-lanthanum-140 concentrations were below the LLD of 15 pCi/L and Cesium-137 concentrations were below the LLD of 10 pCi/L in all samples. Potassium-40 results are similar at both the indicator and control locations (1413 and 1409 pCi/L, respectively), and are essentially identical to the levels observed from 1989 through 2000. There was no indication of any effect due to the operation of the KNPP.

Due to the chemical similarities between strontium and calcium, and cesium and potassium, organisms tend to deposit cesium-1 37 in the soft tissue and muscle and strontium-89 and strontium 90 in the bone. Consequently, ratios of strontium-90 activity to the weight of calcium in milk and cesium-137 activity to the weight of potassium in milk were monitored in order to detect potential environmental accumulation of these radionuclides. The measured concentrations of stable potassium and calcium are in agreement with previously determined values of 1.50 + 0.21 g/L and 1.16 +/- 0.08 g/L, respectively (National Center for Radiological Health, 1968).

Well Water Gross alpha and gross beta concentrations, measured at the two on-site wells (K-lg and K-lh),

averaged 3.5 pCi/L and 4.9 pCi/L respectively. Gross beta measurements for location K-10 averaged 5.6 pCi/L in the first and second quarters of 2001, accompanied by increased levels of naturally occurring potassium-40. Other well water samples, both indicators and control, measured below the LLD level of 4.0 pCi/L and are similar to values observed from 1989 through 2000.

Levels of tritium and strontium-89 and -90 were measured for the on-site well (K-1g). Tritium measured below the LLD of 330 pCi/L in all samples. Concentrations of strontium-89 and strontium 90 were below the detection limits of 1.1 and 0.6 pCi/L, respectively.

All gamma-emitting isotopes measured below their respective LLDs in all samples.

Potassium-40 averages are generally in proportion to gross beta measurements and were in agreement with previously measured values. No plant effect was indicated.

Domestic Meat In domestic meat samples, gross alpha concentration measured below the lower limit of detection for both indicator and control locations. Gross beta concentration averaged 3.0 pCi/g wet for indicator locations and 2.7 pCi/g wet for the control location. The differences are not significant. Gamma spectroscopic analyses showed that almost all of the beta activity was due to naturally occurring potassium-40. All other gamma-emitting isotopes were below their respective LLD limits.

In egg samples, gross beta concentrations averaged 1.45 pCi/g wet for the indicator location and 1.27 pCi/g wet for the control, almost identical to the concentrations of naturally-occurring potassium 40 observed in the samples ( 1.23 and 1.26 pCi/g wet respectively). Other gamma-emitting isotopes were below their respective LLDs. Levels of strontium-89 measured below the LLD of 0.012 pCi/g wet in all samples, strontium-90 measured below the LLD level of 0.005 pCi/g wet.

Ve.getables and Grain In vegetables, gross beta concentrations were similar at both the indicator and control locations (3.19 and 2.56 pCi/g wet, respectively), due primarily to potassium-40 activity. All other gamma L

emitting isotopes measured below their respective LLDs. Strontium-89 measured below the LLD level of 0.023 pCi/g wet in all samples. A low level of strontium-90 was detected in five of eleven samples collected from both control and indicator locations and averaged 0.025 pCi/g wet. Li In two grain samples (clover and oats) from location K-23, gross beta concentrations averaged 11.53 pCi/g wet, due primarily to potassium-40 activity ( 11.22 pCi/g wet).

Trace beryllium-7 was detected in one of the two grain samples. Strontium-89 measured below the LLD levels of 0.067 pCi/g wet, strontium-90 averaged 0.038 pCi/g wet for both samples measured.

Grass and Cattle Feed In grass, mean gross beta concentrations measured 7.79 and 10.50 pCi/g wet at indicator and control locations, respectively, and in all cases was predominantly due to naturally occurring potassium-40 and beryllium-7. All other gamma-emitting isotopes were below their respective LLDs.

No Strontium-89 and Strontium-90 could be detected above the LLD value of 0.051 pCi/g and 0.017 pCi/g wet, respectively. ji In cattlefeed, the mean gross beta concentration was lower at the control locations (8.03 pCi/g wet) than at indicator locations (10.77 pCi/g wet). The highest average gross beta levels were in samples from the indicator locations K-5 (15.16 pCi/g wet), and reflected the high combined beryllium-7 and potassium-40 levels observed in the samples. This pattern was similar to that observed since 1978.

Strontium-89 levels were below the LLD level of 0.028 pCi/g wet in all samples. Strontium-90 activity I.

was detected in both indicator locations and control samples and averaged 0.013 pCi/g wet and 0.018 pCi/g wet, respectively, similar or lower than levels observed in 1995 through 2000. The presence of radiostrontium can still be attributed to fallout from nuclear testing in previous decades. I.

With the exceptions of naturally-occurring beryllium and potassium, gamma-emitting isotopes were below their respective LLD levels.I Soil Gross alpha concentrations in soil samples measured 7.73 pCi/g dry at the indicator locations -i averaged and 9.80 pCi/g dry at the control locations. Mean gross beta levels measured at the indicator and control locations averaged 27.20 and 27.64 pCi/g dry, respectively, primarily due to the potassium-40 activity. Strontium-89 was below the LLD level of 0.073 pCi/g dry in all samples. No Strontium-90 activity could be detected above an LLD limit of 0.029 pCi/g dry.

Low levels of Cesium-1 37 were detected in eight of eleven soil samples and were slightly lower at the indicator locations than at control locations (0.14 and 0.18 pCi/g dry, respectively). Potassium-40 was detected in all samples and averaged 17.62 and 18.35 pCi/g dry at indicator and control locations, respectively. All other gamma-emitting isotopes were below their respective LLD's. These levels of detected activities are similar to those observed from 1989 through 2000.

3.2.4 The Aquatic Environment Surface Water In one surface water, mean gross beta activity was detected at a level of 2.6 pCi/L. All other samples measured below the LLD level of 1.9 pCi/L. Mean gross beta concentration in dissolved solids was higher at the indicator locations (5.9 pCi/L) as compared to the control locations (2.2 pCi/L), similar to activities observed from 1978 through 2000.

The difference in levels are due in part to the indicator location (K-lk), a pond formed by drainage of surrounding fields to the southwest. The control sample is Lake Michigan water, which varies very little in gross beta concentration during the year, while indicator samples include two creek locations (K-la and K-le) which are much higher in gross beta concentration and exhibit large month-to-month variations. The K-la creek draws its water from the surrounding fields which are heavily fertilized; and the K-le creek draws its water mainly from the Sewage Treatment Plant. In general, gross beta concentrations were high when potassium-40 levels were high and low when potassium-40 levels were low, indicating that the fluctuations in beta concentration were due to variations in potassium-40 concentrations and not to plant operations. The fact that similar fluctuations at these locations were observed in the pre-operational studies conducted prior to 1974 supports this assessment.

Tritium was detected in one composite sample from location K-ld for the first quarter, 2001, at a concentration of 767 pCi/L. No tritium was detected above an LLD of 330 pCi/L in all other samples.

Strontium-89 concentrations were below the LLD of 2.5 pCi/L. Strontium-90 measured 1.5 pCi/L in five of twenty-seven indicator samples. All other samples measured below an LLD value of 1,3 pCi/L.

Gamma-emitting isotopes were below their respective LLDs in all samples.

11

11 Fish In fish, gross beta concentrations averaged 3.37 pCi/g wet in muscles and 2.15 pCi/g wet in bone fractions. In muscle, the gross beta concentration was primarily due to potassium-40 activity.

Cesium-137 concentration in muscle was detected in one of six samples tested at a level of 0.040 pCi/g wet, lower than levels observed between 1979 and 1991 (average of 0.12 pCi/g wet), and similar to levels seen in 1992 (0.066 pCi/g wet), in 1993 (0.068 pCi/g wet), in 1994 (0.067 pCi/g wet),

in 1995 (0.056 pCi/g wet), in 1996 (0.055 pCi/g wet), in 1997 (0.053 pCi/g wet), 1998 (0.075 pCi/g wet), in 1999 (0.062 pCi/g wet) and in 2000 (0.063 pCi/g wet).

The strontium-89 concentration was below the LLD of 0.33 pCi/g wet in all samples. Strontium-90 was detected in all bone samples and averaged 0.25 pCi/g wet. p Periphyton (Slime) or Aquatic Vegetation In periphyton (slime) and aquatic vegetation samples, mean gross beta concentrations were slightly higher at the control location than at the indicators (4.60 and 4.28 pCi/g wet, respectively). No strontium-89 or strontium-90 could be detected above the LLD levels of 0.21 and 0.15 pCi/g wet, respectively.

Traces of Co-58 were detected in samples from locations K-Id, K-le and K-14 at an average concentration of 0.079 pCi/g wet.

Cs-137 activity was not detected above an LLD value of 0.045 pCi/g wet, lower than measurements taken from 1989 through 2000. Other gamma-emitting isotopes, with the exception of naturally 1

occurring beryllium-7 and potassium-40, were below their respective LLDs.

Bottom Sediments

[i In bottom sediment samples, the mean gross beta concentrations measured 10.12 pCi/g dry at the indicator locations, and 13.73 pCi/g dry at the control, attributable primarily to levels of potassium-40. .I Cs-134 was below the LLD level of 0.038 pCi/g dry in all samples. Low levels of cesium-137 were detected in five of eight samples from indicator locations and averaged 0.038 pCi/g dry. Two of two control samples averaged 0.092 pCi/g dry. On average, cesium-1 37 measurements are lower than or similar to levels observed from 1979 through 2000.

Levels of strontium-89 measured below the detection limit of 0.070 pCi/g dry in all samples.

Strontium-90 could not be detected above the LLD level of 0.027 pCi/g dry.

3.3 Land Use Census The Land Use Census satisfies the requirements of the KNPP Radiological Environmental Monitoring Manual. Section 2.2.2 states:

"A land use census shall be conducted and shall identify within a distance of 8 km (5 mi.) the location, in each of the 10 meteorological sectors, of the nearest milk animal, the nearest residence and the nearest garden of greater than 50m 2 (500 ft2 )

producing broad leaf vegetation."

The 2001 Land Use Census was an annual census conducted in the years between the complete five year census. This census is used to verify that no changes have occurred with the locations of the nearest residence, milk animal or garden. "Drive-bys" were conducted to verify that no changes have occurred over the previous census.

The Land Use Census was completed on October 2, 2001. This census is conducted annually during the growing season per Health Physics Procedure HP 1.14.

Table 4.6.1 lists the results of the 2001 census. There were no changes identified from the 2000 census.

Table 4.6.2 describes the changes from 2000 to 2001.

I1 Appendix A Interlaboratory Comparison Program Results 11 IA Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides II known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.

I, Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

The results Fn Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request. II II This program was conducted by the U.S. Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2. Results of crosscheck testing with Teledyne Brown Engineering are also listed.

Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.

Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.

IIJ Table A-5 list results of the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.

The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.

The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

Attachment A lists acceptance criteria for "spiked" samples.

Out-of-limit results are explained directly below the result. Ii Al

APPENDIX B DATA REPORTING CONVENTIONS B-1

Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Single Measurements Each single measurement is reported as follows: x+/- s where: x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.

3.0. Duplicate analyses 3.1 Individual results: For two analysis results; x, +/- s, and x 2 S2 Reported result: x +/- s; where x = (1/2) (xi + x 2) and s (1/2) - 2 2 S1 + S2 3.2. Individual results: <L1 , <L 2 Reported result: <L, where L = lower of L, and L2 3.3. Individual results: x +/- s, <L Reported result: x +/- s if x > L; <L otherwise.

4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x,, x2 ... xn are defined as follows:

X =-Y-

"'X _I n -1 q n-i 4.2 Values below the highest lower limit of detection are not included in the average.

4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.

4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.

4.5 In rounding off, the following rules are followed:

4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example, 11.443 is rounded off to 11.44.

4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45.

KEWAUNEE 5.0 GRAPHS OF DATA TRENDS Note: Conventions used in trending data.

The following conventions should be used in the interpretation of the graphs of data trends:

1. Both solid and open data points may be used in the graphs. A solid point indicates an activity, an open point, a lower limit of detection (LLD) value.

2. Data points are connected by a solid line. A break in the plot indicates missing data.

ANNUAL REPORT PART III PROGRAM SELF-ASSESSMENT AND PROGRAM CHANGES Kewaunee's School Forest and wetlands restoration project south of the plant

Kewaunee Nuclear Power Plant Annual Radiological Environmental Monitoring Program Program Self-Assessment Section 2.4.1 .c of the Kewaunee Radiological Environmental Monitoring Manual (REMM) states in part:

"The annualRadiologicalEnvironmentalMonitoringReport shall include ... discussion of all deviationsfrom the sampling schedule of Table 2.2.1-A ..... "

The following is a brief description of the events that occurred during 2000, which deviated from the requirements of the sampling schedule of Table 2.2.1-A. Also included are those items identified in Kewaunee's Assessment Program (KAP) as deviations, descrepancies, and/or problems encountered in the program as a whole.

NOTE: PartI, pg 6 also includes a list of missed samples identified by Environmental,Inc.

1. The following was identified on 1/25/2001, During the repair of an environmental monitoring pump, it was noted that the bearings for the motor were not sealed or shielded. Maintenance does not grease these bearings when they are in the field, which could cause premature failure of the bearings. Evaluate the use of a shielded bearing of the same style in this application. The stock inventory list for this pump was modified to include only double shielded bearings. The existing non-shielded bearings were removed from stock. In the future only double shielded bearings will be ordered and used. This was considered a program improvement. (CAP002536)

2. On 06/19/2001 it was identified that the the sample for quarterly well water, gross beta, was missed from location K-12. The first and second quarter for 2001 were missed. The vendor performing the sample collection assumed that since K-12 was removed from the milk sampling requirement, that it was also removed from the well water sample requirement. K 25 replaced K-12 for the milk sample. Subsequently, starting with the third quarter of 2001, K-25 replaced K-12 for the well water sample also. The KNPP program has four locations for well water samples, only 1-3 are required by the REMP. (KAP WO 01-003842-000) 3 On 06/19/2001 it was identified that sample K-Id (Condensor Discharge) showed tritium at 767 picoCi/L in the first quarter composite for 2001. Maximum permissible concentration is 1,000,000 picoCi/L. No limits were violoated. The Chemistry Department performed an investigation. The records were reviewed and indicated that no releases occurred during environmental sampling for January or February. In March a release was started at 1020 on 3/1/01 and continued through the day. The environmental sample was taken between 1200 and 1400 on 3/1/01.

The tritium in the discharge plume was calculated to be 2.39E-6 microCi/L. Since this was a three month composite sample, the tritium in the environmental sample was calculated to be 7.97E-7 microCi/L or 797 picoCi/L. The result reported was consistant with expectations.

(CAPOO2007)

4. On 8/21/2001, it was identified during a routine Chemistry Job Observation that several procedural weaknesses were observed in SP63-164, Environmental Sample Collection. Five weaknesses were identified in revision "W" of SP63-164. 1) Steps 2.2 and 4.1.e are the only references to the fact that the air sampler at K-31 is in a substation. Neither step refers the performer to obtain the key from Security to access the substation. 2)The procedure does not refer the performer to notify WPSC System Operating upon entry into the substation.

3)WPSC Safety Rules 702 and 704C on substation safety are not referenced in the procedure.

4)Steps 6.1.1 and 6.1.4 direct the recording of check results on the data sheet. However, only a single space is available to record the check results. 5)Between steps 6.1.6 and 6.1.7, a note directs that "filters must be labeled with location codes and flow direction". The charcoal cartridges are so identified, but the particulate filter paper is not. The procedure was revised and addressed all the weaknesses identified. This was considered a program improvement.

(CAP001648) 1

5. On 9/17/2001, it was identified that the KNPP was unable to collect milk samples from location K-35 (Ducat Farm) due to the owners desire to leave the program. Two new locations were identified, K-37 (Hardtke Farm) and K-38 (Sinkula Farm). REMM Revisions wer submitted to typing on 2/13/02. Sample collection from the new locations were started on 3/1/02. The REMP contains extra milk sample locations and did not fall below the minimum requirements for milk samples as stated in the REMM. (CAP001586)

6. On 10/19/2001, it was identified that a precipitation sample was missed for the month of August (K-1 1). Previous samples were obtained for months in the year 2001. The sample I

was missed because there wasn't enough precipitation that month to provide a sample.

(CAPOOl 1107). I

7. On 10/19/2001, a single adverse point was identified. The istope, Cobalt-58 (CO-58) was seen at locations K-Id (Condensor Discharge) and K-14 (Two Creeks Park) in the 7/2/01 environmental sample of slime and aquatic vegatation. The results were 0.064 picoCi/L and L

0.114 picoCi/L respectively. The repoarting level to the NRC is 1,000 picoCi/L. This is not reportable, but the KNPP typically has levels less than LLD. A Chemistry evalaution was performed to see if anything could be attributed to the KNPP. A review of the radiological liquid waste discharge permits found that 16 out of about 60 permits indicated CO-58 concentrations greater than LLD. The highest was on 4-18-01 and was 2.5E-5 microCi/ml.

The liquid waste tanks released near the environmental sampling time was on 6-25-01 and was 4E-7 microCi/ml which was lower than the average (3E-6 microCi/ml). A review of the last few years of the Annual Environmental Monitoring Report showed it was not unusual to see CO-58 at sample point K-ld (Condensor Discharge) of 0.022-0.062 picoCi/L.

U U

The data review did not show any specific release that could account for the activity seen.

Subsequent samples for the year at these locations were below the LLD. (KAP WO 01 016999-000)

8. On 12/19/2001, it was identified that the weekly air particulate sample and biweekly iodine cartridge from K-16 (Green Bay WPS Headquarters) was lost in transit from the Green Bay WPS Environmental Lab out to the Kewaunee Plant. (CAP000304).

Qaulity Assurance Audits Performed Audit 01-002 An audit of the Radiological Environmental Monitoring Program was conducted to verify that the program was being conducted in accordance with the Radiological Environmental Monitoring Manual (REMM) and applicable regulations. The revision control process for the REMM was reviewed along with its' implementing procedures. Sample collection activities were monitored. The condition of sample collection equipment was observed and maintenance records were reviewed. A review was conducted of the vendor audit and verification that the vendor was on the Qualified Suppliers List.

Routine Radiological Environmental Monitoring Reports and Surveillance records were reviewed The review of previous audits, assessments and KAPs did not reveal any adverse trends.Recommendations from the annual American Nuclear Insurance audit had been entered into the corrective action process and were being addressed. The review of three findings, from the previous program audit (99-002), found the corrective actions to be effective.

The review found that Technical Specification Requirements had been appropriately incorporated into the Radiological Environmental Monitoring Manual. Differences existed between the REMM and the sample locations listed in SP-63-164, Environmental Sample Collection. These differences were due to the unavailability of milk samples from some locations. This had been appropriately documented in the corrective action process and the REMM has been revised.

A review of SP-63-280, Annual Environmental Reports, was conducted for the years 1999 and 2000. The required Land Use Census information was contained in the reports and the Technical Specification requirement for submitting the annual report had been met. REMM Table 2.2.1-D lists a reporting level for 1-13 1 in water, but the water samples were not being analyzed for 1-13 1.

CAP002203 Evaluate if the sample requirements for 1-131 should be added to Table 2.2.L.A of the REMM.

1 11 The vendor laboratory was verified to be on the Qualified Supplier List. The last supplier audit found the laboratory to have an adequate and effective quality program that met the requirements of Regulatory Guide 4.13 and 4.15 for the supply of environmental analysis services. I Observations of sample collection determined that all procedure requirements were being met, sample integrity was maintained and the chemist was knowledgeable of the activity. The jJ chemists were observed to be using proper safety precautions and personnel protective equipment.

Based on interviews with Chemistry and HP personnel, review of documentation and observation of sampling activities, it is concluded that the Environmental Radiological Monitoring Program is being effectively implemented as required by the Technical Specifications, regulations, Radiological Environmental Monitoring Manual and implementing procedures.

Program Changes Revision 6 of the REMM was approved on 4/30/2001. A description of the changes, the safety review and evaluation as per 10CFR50.59, and a copy of Revision 6 are attached.

Safety Review Radiological Environmental Monitoring Manual (REMM)

Revision 6 The Kewaunee Nuclear Power Plant Radiological Environmental Monitoring Manual is being revised at this time because of several milk locations that retired from farming and were replaced with new locations. The REMM is the implementing document for the Radiological Environmental Monitoring Program (REMP). These changes are as outlined below.

Removed K-6 (The Novitsky Farm), K- 19 (The Paral Farm), K-4 (The Stangel Farm), and K- 12 (The LeCaptain Farm) from the milk,grass,cattlefeed,TLD and soil sampling program. The listed farms have either retired from farming or sold their cows. In either case, the required samples were no longer available.

Added K-33 (The Holly Farm), K-34 (The Struck Farm), and K-25 (The Wotachek Farm) to the milk,grass,cattlefeed,TLD, and soils sampling program. The farms replaced K-6, K-19 and K-4 respectively.

K-12 (The LeCaptain Farm) was not replaced. A farmer in a suitable location, who was willing to participate in the program was not identified. Kewaunee's REMM has more samples than what is required by NUREG 0472.

After 3 months in the program, K-33 (The Holly Farn) no longer wanted to participate in the milk sampling program. This location was left in the REMM for reference but the sampling requirements were removed at the farmers request.

Added K-35 (The Ducat Farm) to the milk,grass,cattlefeed,TLD, and soil sampling program to replace K-33.

Added K-36 (Fiala's Fish Market, Kewaunee) to the fish sampling program as a commercial fisherman in the area.

Question 1 Is this a change in the facility orprocedures as describedin the USAR or does this conduct tests or experiments not describedin the USAR ?

YES - The revision to the REMM is considered to be a change in the facility or procedures as described in the USAR.

ITI The REMM is a licensing basis document due to it's docketed history. The REMM was incorporated into the Technical Specifications (TS) by TS Amendment No. 64 which took effect on 1/1/86. They were subsequently removed from TS Section 7/8 and made stand alone documents on 12/9/93 by TS Amendment No. 104 in response to NRC Generic Letter 89-01.

USAR Sections 1.8 (NRC General Design Criteria) and 2.8 (Environmental Radioactivity Program) were also reviewed. Page 1.8-8 of the USAR answers the NRC GDC-17 by saying that II the environmental radiation monitoring system is described in Section 2. Page 2.8-1 discusses the preoperational environmental radiological monitoring program, discusses the removal of the ODCM from TS, and discusses that the REMM defines the program for environmental radioactivity sampling. No changes to the formal USAR are required.

The changes being made under Revision 6 of the REMM do not conduct tests or experiments not described in the USAR. [

The changes to the REMM described above effectively remove 4 farm locations from the milk sampling program and replaces them with 3 comparable farm locations. This change is acceptable because Kewaunee had, and will continue to have, more sampling locations than what is required by NUREG- 0472. The addition of the extra commercial fish location is an enhancement to the program which adds flexibility.

Question22 Does this involve a chnge in the Technical Specifications ?

NO - This revision to the REMM does not involve a change to the Technical Specifications.

The REMP is required by TS 6.16.b.2. These changes do not detract from or delete the purpose of the REMP. The program continues to conform to the guidance of Section IV.B.2 of Appendix I to 10CFR50, and NUREG-0472 (Draft).

Safety Evaluation Report Radiological Environmental Monitoring Manual (REMM)

Revision 6 The Kewaunee Nuclear Power Plant Radiological Environmental Monitoring Manual is being revised at this time because of several milk locations that retired from fanning and were replaced with new locations. The REMM is the implementing document for the Radiological Environmental Monitoring Program (REMP). The changes are as outlined in the Safety Review.

Question 1 Could the change increase the probabilityof occurrenceof an accidentpreviously evaluated in the USAR?

No. These changes to the REMM do not affect any structures, systems or components that are capable of initiating an accident previously analyzed in the USAR. The REMP and any of its equipment are not considered an initiator of any accident. Therefore, these changes cannot increase the probability of occurrence of an accident in the USAR.

Question 2 Could the change increase the consequences of an accidentpreviously evaluated in the USAR?

No. Changing the REMM cannot increase the consequences of an accident. The purpose of the REMM is to identify radiological environmental effects in order to monitor and evaluate radiation exposure to members of the public. The REMP can monitor conditions during an accident but it does not cause or mitigate any accidents discussed in the USAR. The existing degree of protection of public health and safety will be maintained.

Question 3 Could the change increase the probability of occurence of a malfunction of equipment important to safety previously evaluated in the USAR?

No. Changes to the REMM cannot increase the probability of occurence of a malfunction of equipment important to safety previously evaluated in the USAR. That is because no equipment defined as "important to safety" interacts directly with any equipment used to support the REMP.

Environmental sample collection and analysis take place outside the protected area of KNPP.

I1 J.

Question 4 Could the change increase the consequences of a malfunction of equipment importantto safety previously evaluated in the USAR?

No. No equipment important to safety is involved in implementing the REMP and these changes to the REMM do not alter that fact. Therefore, if no safety related equipment is involved with these 1

changes then these changes cannot increase the consequences of a malfunction of that equipment. L Question 5 Could the change create the possibility of an accident of a different type than any previously evaluated ini the USAR?

No. These changes to the REMM cannot create the possibility of an accident of a different type thanL previously evaluated in the USAR. The REMP is strictly a passive program that is designed to detect changes in the environment that may be caused by plant operation. Making changes to the REMM beyond the protected area of the plant cannot cause an accident nor can it create an accident of a type L

different from those evaluated in the USAR.

Question 6 Could the change create the possibility of a malfunction of equipment important to safety of a different type than any previously evaluatedin the USAR?

U No. These changes to the REMM do not affect failure modes of any structure, system or component required to mitigate the consequences of an accident. Environmental monitoring involves no equipment important to safety, therefore it cannot cause nor create a malfunction of equipment important to safety of any type regardless of those evaluated within the USAR.

Question7 L Could the change reduce the margin of safety as defined in the basisfor any Technical Specification?

No. The changes to the REMM do not reduce the margin of safety as defined in the basis for Technical Specifications. The REMM is implemented in accordance with 10CFR50, Appendix U

I; 10CFR20, Subpart D; and 40CFRI 90. Numerical guides for design objectives to ensure that radioactive materials released to unrestricted areas are kept ALARA are set forth in Section II of K

10CFR50 Appendix I. Those objectives along with the guidelines of NUREG-0472 form the basis for the REMM. The changes to the REMM described above effectively remove 4 farm locations from the milk sampling program and replaces them with 3 comparable farm locations.

K This change is acceptable because Kewaunee had, and will continue to have, more sampling locations than what is required by NUREG- 0472. The addition of the extra commercial fish location is an enhancement to the program which adds flexibility. Therefore, the margin of safety as defined in the basis for Technical Specifications is not reduced.

1.0 Introduction 1.1 Purpose The purpose of this document is to define the Radiological Environmental Monitoring Program (REMP) for the Wisconsin Public Service Corporation (WPSC) Kewaunee Nuclear Power Plant (KNPP). The REMP is required by KNPP Technical Specification (TS) 6.16.b.2, "Radiological Environmental Monitoring Program."

This document is known as the Radiological Environmental Monitoring Manual (REMM) and is intended to serve as a tool for program administration and as a guidance document for contractors which implement the monitoring program.

1.2 Scope This program defines the sampling and analysis schedule which was developed to provide representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the high potential radiation exposures of MEMBERS OF THE PUBLIC resulting from plant operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and thereby verifies that the measurable concentrations of radioactivity and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways. Guidance for the development of this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring. This program has been developed in accordance with NUREG 0472.

The program will provide field and analytical data on the air, aquatic, and terrestrial radioecology of the area near the Kewaunee Nuclear Power Plant so as to:

1. Determine the effects of the operation of the Kewaunee Nuclear Power Plant on the environment;

3. Provide data on the radiation dose to the public by direct or indirect pathways of exposure.

1.3 Implementation This document is considered, by reference, to be part of the Offsite Dose Calculation Manual. This is as required by KNPP TS 6.16.b.2. The REMM is controlled as a separate document for ease of revision, use in the field and use by contractors. This format was approved by the NRC as part of Rev. 6 1-1 04/30/2001

U TS Amendment No. 64 which provided Radiological Effluent Technical Specifications (RETS) for KNPP.

The REMP is setup to be implemented by a vendor and controlled by WPSC in accordance with U Nuclear Administrative Directive (NAD) 1.20 "Radiological Environmental Monitoring Program".

Monthly reviews of the vendor's progress report are checked and approved by WPSC in accordance with Surveillance Procedure SP 63-276. Annual reviews and submittals of the vendor's report and raw data to the US NRC are checked and approved by WPSC in accordance with Surveillance Procedure SP 63-280. All sample collection, preparation, and analysis are performed by the vendor except where noted. Surveillance Procedure SP 63-164 outlines the environmental sample collection L performed by WPSC. Current vendor Quality Control Program Manuals and implementing procedures shall be kept on file at KNPP.

Periodic reviews of monitoring data and an annual land use census will be used to develop modifications to the existing monitoring program. Upon approval, these modifications will be incorporated into this document so that it will accurately reflect the current radiological environmental monitoring program in effect for the Kewaunee Nuclear Power Plant.

The remainder of this document is divided into two sections. The first section, 2.0 REMP Requirements, describes the different TS and REMM requirements associated with the REMP. The second section, 3.0 REMP Implementation, describes the specific requirements used to implement L the REMP.

U II Rev. 6 1-2 04/30/2001

2.0 REMP Requirements KNPP TS Amendment No. 104 implemented the guidance provided in Generic Letter 89-01, "Implementation of Programmatic Controls for Radiological Effluent Technical Specifications (RETS)." These changes included: 1) incorporation ofprogrammaticcontrols in the Administrative Controls section of the TS to satisfy existing regulatory requirements for RETS, and 2) relocation of the proceduraldetails on radioactive effluents monitoring, radiological environmental monitoring, reporting details, and other related specifications from the TS to the ODCM. Relocating the procedural details to the ODCM allows for revising these requirements using the 10 CFR 50.59 process instead of requiring prior NRC approval using the TS Amendment process.

The RETS requirements were incorporated verbatim into the ODCM with Revision 6. Several of these requirements pertain only to the environmental monitoring program and therefore have been relocated into this document (REMM, Revision 3 and 4) and are identified as REMM requirements.

2.1 Technical Specification Requirements Technical Specification 6.16.b.2 provides the programmatic control, which requires a program to monitor the radiation and radionuclides in the environs of the plant. This is the reason for the existence of the REMP. TS 6.16.b.2 also provides the programmatic control which requires: (a) the program to perform the monitoring, sampling, analysis, and reporting in accordance with the methodology and parameters in the ODCM, (b) a land use census to be performed, and (c) participation in an Interlaboratory Comparison Program. The details of each requirement are described in the REMM requirements stated below.

Technical Specification 6.9.b. 1 requires an "Annual Radiological Environmental Monitoring Report" be submitted to the NRC each year. The specific contents of this report are detailed in REMM 2.4.1.

Additional specific reporting requirements are listed in the other REMM requirements.

2.2 REMM Requirements The following REMM requirements include the procedural details that were originally located in the KNPP RETS section and then relocated into Revision 6 of the ODCM, as discussed above. These requirements are specific to the radiological environmental monitoring program and have been relocated into this document for ease of use and completeness.

The REMM requirements for the Monitoring Program, Land Use Census, and the Interlaboratory Comparison Program include a detailed specification (numbered 2.2.1, 2.2.2, & 2.2.3 respectively) and an associated surveillance requirement (numbered 2.3.1, 2.3.2, & 2.3.3 respectively), along with the basis for the requirement. Reporting requirements are listed in specification REMM 2.4.1.

Rev. 6 2-1 04/30/2001

__ I1 General requirements also apply to all ODCM and REMM requirements (specifications 3.01, 3.02, 3.03, 4.01, 4.02, and 4.03). The requirements are located in the ODCM and are repeated here for convenience.

GENERAL SPECIFICATIONS I 3.0.1 Compliance with the specifications contained in the succeeding text is required during the conditions specified therein; except that upon failure to meet the specifications, the associated ACTION requirements shall be met.

3.0.2 Noncompliance with a Specification shall exist when its requirements and associated ACTION requirements are not met within the specified time intervals. If the Specification is restored prior to I

expiration of the specified time intervals, completion of the Action requirements is not required.

3.0.3 When a Specification is not met, except as provided in the associated ACTION requirements, reporting pursuant to TS 6.9.b and REMM 2.4.1 will be initiated.

SURVEILLANCE REQUIREMENTS I 4.0.1 Surveillance Requirements shall be met during the conditions specified for individual Specifications unless otherwise stated in an individual Surveillance Requirement.

4.0.2 Each Surveillance Requirement shall be performed within the specified time interval with a maximum allowable extension not to exceed 25 % of the surveillance interval.

4.0.3 Failure to perform a Surveillance Requirement within the specified time interval shall constitute a failure to meet the OPERABILITY requirements for a Specification. Exceptions to these requirements are stated in the individual Specification. Surveillance Requirements do not have to be performed on inoperable equipment.

SURVEILLANCE REQUIREMENTS [LI 2.3.1 The radiological environmental monitoring samples shall be collected pursuant to Table 2.2. 1-A from the specific locations given in the table and figure(s) in the REMM, and shall be analyzed pursuant to the requirements of Table 2.2.1-A and the detection capabilities required by Table 2.3.1-A. U BASISU The radiological environmental monitoring program required by this specification provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and U

thereby supplements the radiological effluent monitoring program 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 the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring. Program changes may be initiated based on operational experience. I The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs). The LLDs required by Table 2.3.1-A are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defimed as a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

3.6 Sample Descriptions A description of each of the samples required by this program follows:

Airborne Particulates a

Airborne particulates are collected at six locations (K-If, K-2, K-7, K-8, K-16, K-31) on rate continuous basis on a 47 mm diameter membrane filter of 0.8 micron porosity at a volumetric weekly, placed in of approximately one cubic foot per minute (CFM). The filters are changed Analysis glassine protective envelopes, and dispatched by U.S. Mail to TTVML for Gamma Isotopic sufficient time (ref. SP 63-164). Filter samples are analyzed weekly for gross beta activity after If gross beta (usually 3 to 5 days) has elapsed to allow decay of Radon and Thoron daughters.

the control concentration in air particulate samples are greater than ten (10) times the yearly mean of samples. Quarterly samples, gamma isotopic analysis shall be performed on the individual detector. All composites from each location receive Gamma Isotopic Analysis using 3a Germanium identifiable gamma-emitters are quantified. Reporting units are pCi/m .

Airborne Iodine for collection All air samplers are equipped with charcoal traps installed behind the particulate filters by Gamma of airborne 1-131. The traps are changed once every two weeks. Iodine-131 is measured Isotopic Analysis.

Periphyton (Slime) or Aquatic Vegetation surface water Periphyton (slime) or aquatic plant samples are collected at or near locations used for The samples sampling. They are collected twice during the year (2nd and 3rd quarter) if available.

Sr-90, and by are analyzed for gross beta activity and, if available in sufficient quantity, for Sr-89, Gamma Isotopic Analysis. Reporting units are pCi/g wet weight.

Fish discharge area Fish is collected three times per year (second, third, and fourth quarters) near the (K-id) (ref. RC-C-207 a W Flesh is separated from the are analyzed bones and analyzed for gross beta activity and by Gamma Isotopic Analysis. The bones for gross beta activity and Sr-89 and Sr-90. Reporting units are pCi/g wet weight.

Rev. 6 3-3 04/30/2001

1 11 Domestic Meat U Domestic meat (chickens) is collected once a year during the 3rd quarter, at five locations in the vicinity of the plant (K-20, K-24, K-27, K-29 B K-32). Samples may not be available every year at every location due to farmer preference. At least one control and one indicator should be K

collected. The flesh is analyzed for gross alpha, gross beta, and by Gamma Isotopic Analysis to identify and quantify gamma-emitting radionuclides. Reporting units are pCi/g wet weight. L Ambient Radiation Two packets of thermoluminescent dosimeters (CaSO,: Dy cards) are placed at fourteen locations, six of which are air sampling locations I and four of which are milk sampling locations (K-3, K-5,

and f ); the remaining four locations are M , K-17, K-27,

K-30. One packet is changed quarterly and one annually. Annual TLDs will serve as an emergency set to be read when needed. They will be exchanged annually (without reading) if not read during the year. To insure the precision of the measurement, each packet will contain two cards with four dosimeters each (four sensitive areas each for a total of eight). For protection against Ii moisture each set of cards is sealed in a plastic bag and placed in a plastic container. I Each card is individually calibrated for self-irradiation and light response. Fading is guaranteed by the manufacturer (Teledyne Isotopes) not to exceed 20% in one year. Minimum sensitivity for the multi-area dosimeter is 0.5 mR defined as 3 times the standard deviation of the background.

Maximum Error (I standard deviation) - 6oCo Gamma +/-0.2 mR or +/-3%, whichever is greater. The maximum spread between areas on the same dosimeter is 3.5% at I standard deviation.

Reporting units for TLDs are mR/91 days for quarterly TLDs and mR/exposure period for annual TLDs. II Tests for uniformity and reproducibility of TLDs as specified in ANSI N545-1981 and NRC Regulatory Guide 4.13, are performed annually.

f Well Water One-gallon water samples are taken once every three months from four offsite wells, (K-10, K-11, K-12, K-13) and two onsite wells (K-lh and K-lg). All samples are analyzed for gross beta in the total residue, K-40, and by Gamma Isotopic Analysis. Samples from one onsite well are analyzed I

for Sr-89, Sr-90, and for tritium. Samples from K-lh and K-lg are also analyzed for gross alpha. Reporting units are pCi/l.

Precipitation A monthly cumulative sample of precipitation is taken at Location K-1 1. This sample is analyzed for tritium. Reporting units are pCi/l. I Rev. 6 3-4 04/30/2001 I

Milk Milk samples are collected from MM herds that graze within three miles of the reactor site W ; from three herds that graze between 3-7 miles of the reactor site (K-3, K-5,; " E one from a dairy in Green Bay (K-28), 26 miles from the reactor site.

The samples are collected twice per month during the grazing period (May through October) and monthly for the rest of the year. To prevent spoilage the samples are treated with preservative. All samples are analyzed by Gamma Isotopic Analysis and for iodine -131 immediately after they are received at the laboratory. To achieve required minimum sensitivity of 0.5 pCi/1, iodine is separated on an ion exchange column, precipitated as palladium iodide and beta counted. Monthly samples and monthly composites of semimonthly samples are then analyzed for Sr-89 and Sr-90. Potassium and calcium are determined and the '37Cs/gK and 'Sr/gCa ratios are calculated. Reporting units are pCi/l except for stable potassium and calcium, which are reported in g/l.

If milk samples are not available, green leafy vegetables will be collected on a monthly basis (when available) from Locations K-10, K-11, and K-26.

Grass Grass is collected three times per year (2nd, 3rd, and 4th quarters) from the N dairy farms (K-3, K-5, -T . and from two onsite locations (K-lb and K-If). The samples are analyzed for gross beta activity, for Sr-89 and Sr-90, and Gamma Isotopic Analysis to identify and quantify gamma-emitting radionuclides. Reporting units are pCi/g wet weight.

Cattlefeed Once per year, during the first quarter when grass is not available, cattlefeed (such as hay or silage) is collected from the = dairy farms. The analyses performed are the same as for grass. Reporting units are pCi/g wet weight.

Vegetables and Grain Annually, during the 3rd quarter, samples of five varieties of vegetables grown and marketed for human consumption are collected from K-17 and/or K-26, depending upon the availability of samples. In addition, two varieties of grain, if available, are collected annually from the farmland owned by WPS (K-23) and rented to a private individual for growing crops. The analyses performed are the same as for grass. Reporting units are pCi/g wet weight.

Quarterly samples of eggs can be taken from K-24, K-27, M K-32. At least one control and one indicator should be collected. The samples are analyzed for gross beta activity, for Sr-89 and Sr-90, Rev. 6 3-5 04/30/2001

I'L-and Gamma Isotopic Analysis to identify and quantify gamma-emitting radionuclides. Reporting units are pCi/g wet weight.

Soil Twice during the growing season samples of the top two inches of soil are collected from the dairy farms and from an onsite location (K-1f). The soil is analyzed for gross alpha and gross beta activities, for Sr-89 and Sr-90, and Gamma Isotopic Analysis to identify and quantify gamma emitting manmade radionuclides. Reporting units are pCi/g dry weight. LI Surface Water Surface water is sampled monthly from Lake Michigan at the KNPP discharge (K-ld), and at Two Creeks Park, 2.5 miles south of the reactor site (K-14). Samples are collected monthly at the Green Bay Municipal Pumping station between Kewaunee and Green Bay (K-9). Raw and treated water [j is collected. Monthly samples are also taken, when available, from each of the three creeks (K-la, K-lb, K-le) that pass through the reactor site and from the drainage pond (K-1k) south of the plant. The samples are taken at a point near the mouth of each creek and at the shore of the drainage pond. The water is analyzed for gross beta activity in: (a) the total residue, (b) the dissolved solids, I

and (c) the suspended solids.

The samples are also analyzed for K-40 and by Gamma Isotopic Analysis. Quarterly composites from all locations are analyzed for tritium, Sr-89 and Sr-90. Reporting units are pCi/l.

Bottom Sediments Five samples of Lake Michigan bottom sediments, one at the discharge (K-Id), one from 500 feet north of the discharge (K-ic), one from 500 feet south of the discharge (K-lj), and one at the Two Creeks Park (K-14), one at the Green Bay Municipal Pumping Station (K-9) are collected f semiannually (May and November). The samples are collected at the beach in about 2-3 feet of water. All samples are analyzed for gross beta activity, for Sr-89 and Sr-90 and by Gamma isotopic Analysis. Since it is known that the specific activity of the sediments (i.e., the amount of ]

radioactivity per unit mass of sediment) increases with decreasing particle size, the sampling procedure will assure collection of very fine particles. Reporting units are pCi/g dry weight. jj Rev. 6 3-6 04/30/2001

a. This list does not mean that only these nuclides are to be considered. Other peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radiological Environment Monitoring Report.

L

b. Required detection capabilities for thermoluminescent dosimeters used for environmental measurements are given in Regulatory Guide 4.13.

L

c. The LLD is defined, for purposes of these specifications, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will L

be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system, which may include radiochemical separation: L 4.66sb LLD =

E x V x 2.22 x Y x exp(--yAt) L Where: .]

LLD is the a priori lower limit of detection as defined above, as picocuries per unit mass or volume, L is the standard deviation of the background counting rate or of the counting rate of blank Sb sample as appropriate, as counts per minute, L E is the counting efficiency, as counts per disintegration, ii V is the sample size in units of mass or volume, 2.22 is the number of disintegrations per minute per picocurie, ]

Y is the fractional radiochemical yield, when applicable, y is the radioactive decay constant for the particular radionuclide, and At for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and time of counting, II Typical values of E, V, Y, and At should be used in calculation.

Table Notationsfor Table 2.3.1-A (con 't)

It should be recognized that the LLD is defined as a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement. Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Monitoring Report.

d. If no drinking water pathway exists, a value of 3,000 pCi/1 may be used.

e. LLD for drinking water samples. If no drinking water pathway exists, the LLD of gamma isotopic analysis may be used.

'nvironmentalMonitorin Table Notations a The samples listed in this column describe the minimum sampling required to meet REMP requirements.

b Additional details of sample locations are provided in Table 2.2. I-C and Figure 1. The REMP requires that samples to be taken from each of the "available sample locations" listed (see section 3.1). Deviations from the required sampling schedule will occur specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, reasonable efforts shall be made to complete corrective actions prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented, as required by REMM 2.4.1 .c, in the Annual Radiological Environmental Monitoring Report. It is recognized tha at times, it may not be possible or practicable to continue to obtain samples of the media of choice at the most desired location or time. In these instances suitable alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the REMM. The cause of the unavailability of samples for that pathway and the new location(s) for obtaining replacement samples will be identified in the Annual Radiological Environmental Monitoring Repor c For the purposes of this table, each location will have 2 packets of thermoluminescent dosimeters (TLDs). The TLDs are CaSO4:

Dy cards with 2 cards/packet and 4 dosimeters/card (four sensitive areas each for a total of eight dosimeters/packet). The NRC guidance of 40 stations is not an absolute number. The number of direct radiation monitoring stations has been reduced according to geographical limitations; e.g., Lake Michigan. The frequency of analysis or readout for TLD systems depends upon the characteristics of the specific system used and selection is made to obtain optimum dose information with minimal fading.

d The purpose of this sample is to obtain background information. If it is not practical to establish control locations in accordance with the distance and wind direction criteria, other sites that provide valid background data may be substituted.

radon e Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or more after sampling to allow for daughter decay. If gross beta activity in air particulate samples is greater than ten times the yearly mean of control and thoron samples, gamma isotopic analysis shall be performed on the individual samples.

to f Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable the effluents from the facility.

shall g The "upstream sample" shall be taken at a distance beyond significant influence of the discharge. The "downstream" sample be taken in an area near the mixing zone.

h Ground water samples shall be taken when this source is tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties are suitable for contamination.
