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 2002.

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

Results of sample analyses during the period January - December 2002 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 Pro_ram 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-lf, 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 <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> 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-1f, K-2, K-7, K-8, K-16 and K-31. The filters are changed bi-weekly and analyzed for iodine-131 immediately after arrival at the laboratory.

Ambient Gamma Radiation - TLDs The integrated gamma-ray background is measured at six sampling locations (K-1f, K-2, K-7, K-8, K-15 and K-16), at five milk sampling locations (K-3, K-5, K-25, K-35 and K-37), 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-1I are analyzed for tritium activity and counted using a liquid scintillation method.

3.1.2 The Terrestrial Proqram Milk Milk is collected semimonthly from May through October, and monthly during the rest of the year from four herds that graze within four miles of the reactor site (K-5, K-25, K-34 and K-38), from two herds that graze between four and ten miles from the reactor site (K-3 and K-37), and from a dairy in Green 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-1 0, K-11, K-13 and K-25 and from two on-site wells located at K-1 g and K-1 h.

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, determined by atomic absorption, on all samples.

Additionally, samples of water from two on-site wells (K-1g and K-1h) are analyzed for gross alpha.

Water from the on-site well (K-1 g) 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-29, K-32 and K-34 (if available). The flesh is separated from the bones and analyzed for gross alpha, gross beta and gamma emitting isotopes.

Ecqcs 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 -9g, and gamma emitting isotopes.

Grass and Cattle Feed Grass is collected during the second, third and fourth quarters from two on-site locations (K-1b and K-1f) and from the dairy farm locations. Cattle feed is collected during the first quarter from the same farms. The samples are analyzed for gross beta, strontium-89 and -90, and gamma emitting isotopes.

For the year 2002, six locations for grass collection were available (K-3, K-5, K-25, K-34, K-37 and K-38), cattle feed was available from locations K-3, K-5, K-25, and K-34.

Soil Soil samples are collected twice a year on-site at K-if and from the dairy farm locations (K-3, K-5.

K-25, K-34, K-37 and K-38). The samples are analyzed for gross alpha, gross beta, strontium-89, strontium-90 and gamma emitting isotopes.

3.1.3 The Aquatic Program 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-1d); 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-1a, K-1b, and K-1 e).

Samples from North and Middle Creeks (K-1a, K-lb) are collected near the mouth of each creek.

Samples from the South Creek (K-1 e) are collected about ten feet downstream from the point where the outflow from the two drain pipes meet. Additionally, the drainage pond (K-1k), 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-1d, K-9 and K-14), from three creek locations (K-1a, K-lb and K-le) and from the drainage pond (K-1 k), if available. 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-1c, K-1d, K-1j, 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 Proqram Execution Program execution is summarized in Table 4.4. The program was executed for the year 2002 as described in the preceding sections, with the following exceptions: -

Air particulate I Air iodine samples were not available from location K-1 6 for the weeks ending February, 11 and February 19, 2002. The sampler was out of service.

The air particulate sample from location K-31, for the week ending March 19, 2002, did not represent the total volume collected. The filter, as found, was torn.

No precipitation was available for collection in February, 2002.

Milk, soil and grass was not available from location K-37 (Hardtke Farm) after September, 2002. The farm was dropped from the sampling program.

Vegetables were not available at location K-17, Jansky's Farm. The garden was discontinued.

Surface water was not available for the months of January, February and March, 2002 at locations K-1 a and K-1 k. The creek and pond were both frozen.

Surface water was not available for the month of December, 2002 at locations K-1 k. The pond was frozen.

3.1.5 Program Modifications Two replacement dairies were added in March, 2002, the Hardtke Farm (K-37) and the Sinkula Farm (K-38).

The Hardtke farm had to subsequently withdraw from the program in September, 2002, due to fire.

3.2 Results and Discussion The results for the reporting period January to December 2002 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 2002 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 2002 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 2002. 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 0.023 pCi/m 3 at the indicator locations and 0.022 pCi/m 3 at the controls. The averages were almost identical to the means observed from 1991 (and prior to) through 2001. Results are tabulated below.

Airborne Particulates (continued) -

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 Al-Salih, 1955), was detected in all samples. All other gamma-emitting isotopes were below their respective LLD limits.

Airborne Iodine 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 (16.1 mR/91 days), in agreement with the mean at the control locations of (15.1 mR/91 days), and were similar to the means obtained in 1991 (and prior to) through 2001. 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 19.4 mR/91 days, measured at the indicator location K-7.

Precipitation Precipitation was monitored at one indicator location, K-1 1. The tritium concentration was below the LLD level of 330 pCi/L in all samples.

3.2.3 The Terrestrial Environment Milk Of the 116 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 1.5 pCi/L in all samples. Low levels of strontium-90 were found in all samples tested. Mean values were almost identical for indicator and control locations (1.1 pCi/L and 1.2 pCi/L, respectively) and are similar to or less than averages seen from 1989 through 2001.

Barium-lanthanum-140 concentrations were below the LLD of 15 pCi/L and Cesium-137 concentrations were below the LLD of 10 pCiVL in all samples. Potassium-40 results are similar at both the indicator and control locations (1370 and 1405 pCi/L, respectively), and are essentially identical to the levels observed from 1989 through 2001. 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-137 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-1g and K-1h),

averaged 3.5 pCi/L and 5.1 pCi/L respectively. Other wells tested, both indicators and control, measured below the LLD level of 4.1 pCi/L, similar to values observed from 1989 through 2001.

Levels of tritium and strontium-89, strontium-90 were measured for the on-site well (K-1g). Tritium measured below the LLD of 330 pCilL in all samples. Strontium-89 concentration measured below the LLD value of 1.0 pCVL. A slight strontium-90 concentration of 0.6 pCi/L was measured in one of four samples, above the LLD value of 0.5 pCi/L.

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 3.1 pCi/g wet for indicator locations and 1.8 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.

9

Eqqs In egg samples, gross beta concentrations averaged 1.34 pCUg wet for the indicator location and 1.32 pCi/g wet for the control, almost identical to concentrations of naturally-occurring potassium-40 observed in the samples ( 1.23 and 1.21 pCilg wet respectively). Other gamma-emitting isotopes were below their respective LLDs. Levels of strontium-89 measured below the LLD of 0.017 pCi/g wet in all samples, strontium-90 measured below the LLD level of 0.011 pCi/g wet.

Veqetables and Grain In vegetables, gross beta concentrations measured 2.19 pCi/g wet at the control location K-26, due primarily to potassium-40 activity. All other gamma emitting isotopes measured below respective LLDs. Strontium-89 measured below the LLD level of 0.004 pCi/g wet. A low level of strontium-90 was detected in two of the six samples collected and averaged 0.005 pCilg wet.

In two grain samples (clover and oats) from location K-23, gross beta concentrations averaged 6.65 pCi/g wet, due primarily to potassium-40 and beryllium-7 activity (4.71 and 1.46 pCi/g wet, respectively). Strontium-89 measured below the LLD levels of 0.047 pCVg wet, strontium-90 averaged 0.026 pCi/g wet for both samples measured.

Grass and Cattle Feed In grass, mean gross beta concentrations measured 7.75 and 7.20 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 0.11 pCi/g and 0.046 pCi/g wet, respectively.

In cattlefeed, the mean gross beta concentration was lower at the control locations (7.92 pCi/g wet) than at indicator locations (13.07 pCi/g wet). The highest average gross beta levels were in samples from the indicator locations K-5 (17.95 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 0.096 pCi/g wet in all samples. Strontium-90 activity was detected in both indicator locations and control samples and averaged 0.033 pCi/g wet and 0.012 pCi/g wet, respectively, similar or lower than levels observed in 1995 through 2001. The presence of radiostrontium can still be attributed to fallout from nuclear testing in previous decades.

With the exceptions of naturally-occurring beryllium and potassium, gamma-emitting isotopes were below their respective LLD levels.

Soil Gross alpha concentrations in soil samples measured 7.86 pCVg dry at the indicator locations averaged and 7.93 pCi/g dry at the control locations. Mean gross beta levels measured at the indicator and control locations averaged 27.68 and 29.06 pCi/g dry, respectively, primarily due to the _

potassium-40 activity. Strontium-89 was below the LLD level of 0.077 pCi/g dry in all samples.

Strontium-90 activity was detected in both indicator locations and control samples and averaged 0.083 pCi/g dry and 0.12 pCi/g dry, respectively.

Low levels of Cesium-137 were detected in eleven of thirteen soil samples and were lower at the indicator locations than at control locations (0.085 and 0.17 pCi/g dry, respectively). Potassium-40 was detected in all samples and averaged 17.69 and 19.04 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 2001.

3.2.4 The Aquatic Environment Surface Water In one surface water collected at location K-le, mean gross beta activity in suspended solids was detected at a level of 1.9 pCilL. All other samples measured below the LLD level of 1.2 pCi/L. Mean gross beta concentration in dissolved solids was higher at the indicator locations (5.7 pCi/L) as compared to the control locations (2.2 pCi/L), similar to activities observed from 1978 through 2001.

Average Average Year (Indicators) (Controls)

Dose rate mR/91 davs) 1991 5.1 2.2 1992 4.5 2.2 1993 5.0 2.3 1994 5.0 2.3 1995 4.3 2.2 1996 4.3 2.2 1997 6.3 2.4 1998 5.9 2.1 1999 5.6 2.2 2000 7.0 2.4 2001 5.9 2.2 2002 5.7 2.2 Average annual gross beta concentrations in surface water (DS).

The difference in levels are due in part to the indicator location (K-1k), 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-1 a and K-1 e) which are much higher in gross beta concentration and exhibit large month-to-month variations. The K-1 a 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.

No tritium was detected above an LLD of 330 pCi/L in any sample.

Strontium-89 concentrations were below the LLD of 1.5 pCUL. Strontium-90 measured 0.9 pCi/L in six of twenty-six indicator samples. All other samples measured below an LLD value of 0.7 pCi/L.

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

11

Fish In fish, gross beta concentrations averaged 3.46 pCi/g wet in muscles and 1.17 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 two of seven 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 pCilg wet), in 1994 (0.067 pCilg wet),

in 1995 (0.056 pCi/g wet), in 1996 (0.055 pCi/g wet), in 1997 (0.053 pCilg wet), 1998 (0.075 pCi/g wet), in 1999 (0.062 pCi/g wet), in 2000 (0.063 pCi/g wet) and 0.040 pCi/g wet in 2001.

The strontium-89 concentration was below the LLD of 0.36 pCi/g wet in all samples. Strontium-90 was detected above the LLD value of 0.14 pCi/ g wet in four of seven bone samples tested and averaged 0.24 pCi/g wet.

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 (5.57 and 4.24 pCi/g wet, respectively).

The strontium-89 concentration was below the LLD of 0.18 pCi/g wet in all samples. Strontium-90 was detected above the LLD value of 0.077 pCi/g wet in two of twelve indicator samples, averaging 0.17 pCVg wet.

Cs-137 activity was detected, above the LLD value of 0.035 pCi/g wet, in three of twelve indicator samples, averaging 0.048 pCilg wet, similar or lower than measurements taken from 1989 through 2001. Other gamma-emitting isotopes, with the exception of naturally-occurring beryllium-7 and potassium-40, were below their respective LLDs.

Bottom Sediments In bottom sediment samples, the mean gross beta concentrations measured 8.46 pCi/g dry at the indicator locations, and 22.47 pCi/g dry at the control, attributable primarily to levels of potassium-40.

Cs-134 was below the LLD level of 0.034 pCi/g dry in all samples. Low levels of cesium-137 were detected in six of eight samples from indicator locations and averaged 0.029 pCi/g dry. Two of two control samples averaged 0.091 pCi/g dry. On average, cesium-137 measurements are lower than or similar to levels observed from 1979 through 2001.

Levels of strontium-89 measured below the detection limit of 0.044 pCi/g dry in all samples.

Strontium-90 could not be detected above the LLD level of 0.024 pCilg 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 5m 2 (500 ft2 )

producing broad leaf vegetation."

The 2002 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 September 5, 2002. 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 2002 census. There were no changes identified from the 2001 census.

Table 4.6.2 describes the changes from 2001 to 2002.

Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four Umes a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

Appendix A lnterlaboratorv Comparison Proqram Results 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 containing concentrations of radionuclides 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.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Seve;al 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.

Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. Results of internal laboratory testing is 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. request.

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.

APPENDIX B DATA REPORTING CONVENTIONS B-I

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; xi +/- si and X2 +/- s2 Reported result: x + s; where x = (1/2) (xi + x2) and s = (1/2) S +52 3.2. Individual results: <L1 , <L2 Reoorted result: <L, where L = lower of Li 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 x1 , X2 . . . Xn are defined as follows:

- 1 )2

~~~~~E(x-X n-i 4.2 Values below the highest lower limit of detection are not included in the average. J 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 J is reported.

4.5 In rounding off, the following rules are followed: j 4.5.1. If the number following those to be retained is less than 5, the number is dropped, and the retained number s are kept unchanged. As an example, 11.443 is rounded off to 11.44.

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

KEWAUNEE 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.
