1.0 INTRODUCTION

The Kewaunee Power Station is a 598 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 2006.

Dominion Nuclear, an operating company for the Kewaunee Power Station, assumes the responsibility for the environmental program at the Plant and any questions relating to this subject should be directed to Mr. J. Michael Hale, Radiation -Protection / Chemistry Manager, at (920) 388-8103.

SUMMARY

Results of sample analyses during the period January - December 2006 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 radloactivities in all samples collected.

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

3.1 Methodolog.y 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 <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 on a high-purity germanium (HPGe) detector.

Airborne Iodine Charcoal filters are located at locations K-If, K-2, K-7, K-8, K-1 6 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 the six air sampling locations (K-If, K-2, K-7, K-8, K-16 and K-31), at four milk sampling locations (K-3, K-5, K-25 and K-39), and four additional sites ( K-15, located 9.25 miles northwest of the plant; K-17, located 4.25 miles west of the plant; K-27, located 1.5 miles northwest of the plant and K-30, located 1.0 miles north of the plant ) by thermoluminescent dosimetry (TLDs). Two TLD cards, each having four main readout areas containing CaSO 4: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

3.1.2 The Terrestrial Progqram Milk Milk is collected semimonthly from May through October, and monthly during the rest of the year from five herds that graze within four miles of the reactor site (K-5, K-25, K-34, K-38 and K-39), from one herd grazing between four and ten miles from the reactor site (K-3), and from a dairy in Green Bay (K-28). The samples are analyzed for iodine-131, strontium-89 and strontium-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-I 0, K-1 1, K-I 3 and K-25 and from two on-site wells located at K-I g and K-I h.

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

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

Water from the on-site well (K-Ig) is analyzed for strontium-89 and strontium-90.

Domestic Meat Domestic meat samples are obtained annually (in the third quarter) at locations K-24, K-29 and K-32 and ifavailable at locations K-20, K-27 and K-34. The flesh is separated from the bones and. analyzed for gross alpha, gross beta and gamma emitting isotopes.

Eggs are collected quarterly from locations K-24, K-27 (if available) and K-32. Samples are analyzed for gross beta, strontium-89, strontium-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, strontium-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-I b and K-If) 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.

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-38 and K-39). The samples are analyzed for gross alpha, gross beta, strontium-89, strontium-90 and gamma emitting isotopes.

3.1.3 The Aquatic Proglram 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-la, K-lb, and K-Ie).

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

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

The water is analyzed for gammaemitting 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,' stroritium-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),"frorh . three creek locations (K-Ia, K-lb .and K-le) and from the drainage pond (K-1 k), if available., Thesamplfs are analyzed for gross beta activity. If the quantity is sufficient, analyses for gamma-emitting isotopes and strontium-89 and strontium-90 activities are performed.

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 Program execution is summarized in Table 4.4. The program was executed for the year 2006 as described in the preceding sections, with the following exception:

(1) Vegetable samples were not available at the indicator location K-1 7, Jansky's Farm. The garden has been discontinued. Additional vegetable samples were collected at locations K-34 and K-38.

(2) The surface water from location K-1 k could not be sampled in either March or December.

of 2006. The pond was frozen.

3.1.5 Program Modifications During 2006, no significant changes were made to the Radiological Environmental Monitoring Program.

3.2 Results and Discussion The results for the reporting period January to December 2006 are presented in summary form in Table 4.5. For each type of analysis, of each sampled medium, the 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 Power Station refers to data collected by Environmental Inc., Midwest Laboratory.

The tabulated results of all measurements made in 2006 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 2006 annual report on the Radiological Monitoring Program for the Kewaunee Power Station.

3.2.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no atmospheric nuclear tests or accidents reported in 2006. 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 3

The annual gross beta concentration in air particulates measured 0.021 pCi/m at both the indicator and control locations. The averages were similar to the means observed from 1995 (and prior to) through 2005. 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 AI-Salih, 1955) was detected in all samples, with an average activity of 0.066 pCi/m 3 for all locations. 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 3'

pCi/m at all locations. There is no indication of an effect of plant operation on the local air environment.

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

Quarterly TLDs at indicator locations measured a mean dose equivalent of (15.7 mR/91 days), in agreement with the mean at the control locations of (14.3 mR191 days), and were similar to the-means obtained from 1995 (and prior to) through 2005. 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 19.2 mRI91 days, measured at the indicator location K-7.

3.2.3 The Terrestrial Environment Milk Of 126 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 1.1 pCi/L in all samples. Low levels of strontium-90 were found In eighty one of the eighty four samples tested. Mean values were almost identical for indicator and control locations (1.1 and 1.0 pCi/L, respectively) and are similar to or less than averages seen from 1990 through 2005.

Barium-lanthanum-140 concentrations were below 15 pCi/L and cesium-134 and cesium-137 concentrations were below 10 pCi/L in all samples. Potassium-40 results were almost identical at both the indicator and control locations (1344 and 1341 pCi/L, respectively), and are comparable to levels observed from 1990 through 2005. There was no Indication of any effect due to the operation of the Kewaunee Power Station.

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 Mtrontium-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 1.16i 0.08 g/L, respectively (National Center for Radiological Health, 1968).

Well Water One sample for gross alpha analysis from the two on-site wells (K-I g and K-I h), was measured at the LLD value of 2.8 pCi/L. Gross beta activity, above an LLD of 1.5 pCViL was detected in 16 of the 24 samples tested. Gross beta concentrations averaged 2.6 pCi/L at the indicator locations and 1.6 pCVL for the control location.

Levels of strontium-89 and strontium-90 were measured for the on-site well (K-lg). The concentrations measured below the LLD value of 0.8 and 0.6 pCi/L, respectively.

All samples were tested for tritium and gamma emitting isotopes. Tritium concentrations measured below the LLD of 182 pCi/L. Gamma-emitting isotopes measured below respective LLDs.

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, one sample for gross alpha analysis, from the control location (K-32),

measured 0.11 pCil/gwet, slightly above the lower limit of detection of 0.07 pCVgwet. Gross beta concentration averaged 3.27 pCi/g wet for indicator locations and 2.97 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.

9ý

In egg samples, gross beta concentrations averaged 1.85 pCi/g wet for the indicator location and 1.62 pCi/g wet for the control, similar to concentrations of naturally-occurring potassium-40 observed in the samples ( 1.30 and 1.24 pCi/g wet respectively). Other gamma-emitting isotopes were below their respective LLDs. Levels of strontium-89 measured below- the LLD of 0.010 pCi/g wet in all samples, strontium-90 measured below the LLD level of 0.004 pCi/g wet.

Vegetables and Grain In vegetables, gross beta concentrations averaged 2.45 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 0.009 pCi/g wet. Strontium-90 measured below the LLD level of 0.003 pCig wet.,,

In two grain samples (clover and Oats) from location K-23, gross beta concentrations averaged 8.04 pCi/g wet, due primarily to potassium-40 and beryllium-7 activity (5.21 and 1.29 pCilg wet, respectively). Strontium-89 measured below the LLD level of 0.017 pCVg wet, strontium-90 measured below the LLD level of 0.006 pCi/g wet.

Grass and Cattle Feed In grass, mean gross beta concentrations measured 7.80 and 11.39 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.

Strontium-89 measured below the LLD levels of 0.024. Strontium-90 activity measured below the LLD levels of 0.013 pCVgwet. -

In cattlefeed, the mean gross beta concentration was lower at the control locations (10.37 pCi/g wet) _.

than at indicator locations (15.76 pCi/g wet), and reflected the potassium-40 levels observed in the samples (7.47 and 11.47 pCi/gwet, respectively.). This; pattern is similar to that observed since 1978.

Strontium-89 levels were below the LLD level of 0.032 pCi/g wet in all samples. Low levels of strontium-90 activity, above the LLD value of 0.013 pCi/g wet were detected in five of twelve samples, and averaged 0.017 pCi/g wet, similar or lower than levels observed in 1995 through 2005. The presence of radiostrontium in the environment can still be attributed to fallout from nuclear testing in previous decades.

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

Soil Gross alpha concentrations in soil samples averaged 8.48 pCi/g dry at the indicator locations and 11.41 pCVg dry at the control location. Mean gross beta levels measured at the indicator and control locations averaged 31.52 and 31.79 pCVg dry, respectively, primarily due to the potassium-40 activity.

Strontium-89 was below the LLD level of 0.076 pCVg dry in all samples. Low levels of strontium-90 activity were detected in eight of the fourteen samples tested and averaged 0.049 pCi/g dry.

Low levels of Cesium-137 were detected in twelve of fourteen soil samples, similar at both indicator and control locations (0.14 and 0.19 pCi/g dry, respectively). Potassium-40 was detected in all samples and averaged 20.36 and 19.72 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 2005. The data suggests no evidence of a plant effect on soil.

3.2.4 The Aquatic Environment Surface Water In all surface water samples tested, gross beta activity in suspended solids measured below the LLD level of 1.5 pCi/L. Mean gross beta concentration in dissolved solids was higher at the indicator locations ( 5.5 pCi/L) as compared to the control locations (1.8 pCi/L). The pattern is similar to activity distribution observed from 1978 through 2005. . I .  :

The difference in levels are due in part to the indicator location (K-1 k), 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 the two creek locations (K-I a and K-Ie) which are much higher in gross beta concentration and exhibit large month-to-month variations. The K-Ia 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 activity was observed above a lower limit of detection (LLD) of 186 pCiIL.

Strontium-89 concentrations were below the LLD of 1.3 pCi/L. Strontium-90 averaged 1.0 pCi/L in two of twenty-eight 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 concentration averaged 3.43 pCi/g wet in muscle and 1.99 pCi/g wet in bone fractions. In musde, the gross beta concentration was primarily due to potassium-40 activity.

No cesium-137 activity was observed in muscle samples for 2006, above a detection limit of 0.095 pCi/gwet. This is below levels observed between 1979 and 1991 (average of 0.12 pCi/g wet), and similar to levels seen from 1992 through 2005, averaging 0.060 pCi/gwet.

The strontium-89 concentration was below the LLD of 0.76 pCi/g wet in all samples. Strontium-90 was detected above the LLD Value of 0.05 pCi/g wet and averaged 0.29 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 (5.88 and 4.36 pCi/g wet, respectively), due primarily to combined potassium-40 and beryllium-7 activity (4.46 and 3.65 pCi/g wet, respectively).

Other gamma-emitting isotopes, with the exception of naturally-occurring beryllium-7 and potassium-40, were below their respective LLDs.

The strontium-89 concentration was below the LLD of 0.092 pCi/g wet in all samples. Strontium-90 was not detected above an LLD value of 0.019 pCi/g wet.

Bottom Sediments In bottom sediment samples, the mean gross beta concentrations measured 11.24 pCi/g dry at the indicator locations and 22.03 pCi/g dry at the control location.

Cs-1 34 measured below the LLD level of 0.030 pCi/g dry in all samples. A low level of cesium-1 37 was observed in one of the two control samples tested. The cesium-137 measured 0.080. pCi/g dry.

On average, cesium-137 measurements are lower than or similar to levels observed from 1979 through 2005.

Levels of strontium-89 and strontium-90 measured below respective detection limits of 0.035 pCi/g dry and 0.022 pCi/g in all samples.

3.3 Land Use Census The Land Use Census satisfies the requirements of the KPS 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

. 2 2 -

greater than 50m (500 ft ) producing broad leaf vegetation."

The 2006 Land Use Census was completed to identify the presence of the nearest milk animals, gardens and farm crops of the Kewaunee Power Station.

The Land Use Census was completed on September S, 2006. The census is conducted annually during the growing season per Health Physics Procedure HP 1.14.

Results of the 2006 census are summarized in Table 4.6.Changes from the 2005 census are listed by sector.

In summary, the highest D/Q locations for nearest garden, nearest residence and nearest milk animal did not change from the 2005 census.

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 times a year, the complete Appendix is included in March, June, September and December monthly progress reports only.

January, 2006 through December, 2006

Appendix A Interlaboratory Comparison Pro-ram Results Environmental, Inc., 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. 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.

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 list results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

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.

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.

Attachment A lists acceptance criteria for "spiked" samples.

Oufof-limit results are explained directly below the result.

f Difficulties with the analyses for transuranics isotopes In solid samples (Filters, Soil and vegetation),

were attributed to incomplete dissolution of the samples. Soil samples were repeated, results of reanalyses:

Pu-238, 53.1 +/- 5.3 bqikg. Pu-2391240, 42.4 +/- 4.7 bq/kg. U-233/4, 33.3 +/- 3.5 bq/kg. U-238, 35.5 +/- 3.6 bq/kg.

9 The July vegetation sample was provided in two separate geometries, (100 ml. and 500 ml.). Results reported here used the 500 ml. standard size geometry. Results for the 100 ml. geometry showed approximately a 15% higher bias.

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 = 2a 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 4.66a uncertainty for a background sample.

3.0. Duollcate analyses 3.1 Individual results: For two analysis results; xi +/- s, and x2 + s2 Reported result: x +/- s; where x = (1/2) (xI + x2) and s= (1/2) 1 +S2 3.2. Individual results: < Ll , < L2 Reported result < L, where L = lower of L1 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 . . . x are defined as follows:

7x Sx s- 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 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.

EIML-AB-01 Rev. 3, 07-07-04 DETERMINATION OF GROSS ALPHA ANDIOR GROSS BETA IN SOLID SAMPLES Principle of Method 100 mg to 200 mg of sample Is distributed evenly on a 2n ringed planchet, counted in a proportional counter, and concentrations of gross alpha and /or gross beta are calculated.

A. Vegetation. Meat. Fish. and Wildlife Procedure

1. Weigh out accurately in a planchet no more than 100 mg of ashed or dried and ground sample for gross alpha assay and no more than 200 mg for gross beta assay.

NOTE: If both gross alpha and gross beta analyses are required, do not use more than 100mg.

2. Add a few drops of water and spread uniformly over area of the planchet. Dry under a heat lamp.

NOTE: If necessary, a few drops (6-7) of a lucite solution ( 0.5 mg/ml in acetone) may be added to keep residue in place. Dry under an infrared lamp for 10-20 minutes.

4. Store the planchets in a dessicator until counting.

5. Count the gross alpha and gross beta activity in a low background proportional counter.

GS-01 Rev. 4, 02-08-07 DETERMINATION OF GAMMA EMITTERS BY GAMMA SPECTROSCOPY Principle of Method Samples are weighed or measured into calibrated containers and set directly on an HPGe (high-purity germanium) detector. The sample is counted for a sufficient length of time necessary to reach the required MDA (Minimum Detectable Activity). Results are decay corrected to the date of collection, where appropriate, using a dedicated computer and software.

Refer also to the procedure OP-11, "Operating Procedure for the EG&G ORTEC OMNIGAM Gamma Spectroscopy System".

Procedure A. Milk, Water. and other Liquid Samples

1. Measure with a graduated cylinder, 500 mL, 1.0 L, 2.0 L or 3.5 L of sample into a calibrated sample container (Marinelli beaker). Use the largest volume possible, based on available

-sample quantity.

2. Affix a label to the container cover with the sample number, volume, date and time of collection. Mark "1-131" if analysis for 1-131 by gamma spectroscopy is required.

3. Count for estimated time required to meet the client's specifications. Record file number, sample identification number, date and time counting started, detector number, geometry, sample size, and date and time of collection.

NOTE: Counting priorities should be based on half-life (1-131 / 8.0d, Ba/La-140 / 12.8d, etc.) and MDA requirements of the isotopes to be analyzed for. If possible, samples marked for analysis of 4 1-131 should be counted within two weeks of the collection date.

4. Stop the counting; transfer the spectrum to the disk, and print out the results.

5. Check the results for required MDAs. If the client's specifications are not met, continue the counting.

6. Once the required MDAs have been met, record the counting time.

7. Return the sample to the original container and mark with a red marker.

Principle of Method After samples have -been treated to convert all iodine In the sample to a common oxidation state, the iodine is isolated by solvent extraction or a combination of ion exchange and solvent extraction steps.

Iodine, as the iodide, is concentrated by adsorption on an anion resin. Following a NaCI wash, the iodine is eluted with sodium hypochlorite. Iodine in the Iodate form is reduced to 12 and the elemental iodine extracted into CHCI3 , back-extracted Into water then finally precipitated as palladium iodide.

Chemical recovery of the added carrier is determined gravimetrically from the Pdl2 precipitate. 1-131 Is determined by beta counting the Pdl2 .

SR-02 Reissue, 12-15-04 Determination of Sr-89 and Sr-90 In Water Principle of Method The acidified'sample of. clear water with stable strontium, barium, and calcium carriers is treated with oxalic acid at a pH of 3.0 to precipitate insoluble oxalates. The oxalates are dissolved in nitric acid, and strontium nitrate is separated from calcium as a precipitate in 70% nitric acid. The residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides. After a second strontium nitrate precipitation from 70% nitric acid, the nitrates are dissolved in acid with added yttrium carrier and are stored for ingrowth of yttrium-90. The yttrium is again precipitated as hydroxide and separated from strontium with the strontium being in the supemate. Each fraction is precipitated separately as an oxalate (yttrium) and carbonate (strontium) and collected on No. 42 (2.4 cm) Whatman filter for counting.

SR-05 Reissue, 12-15-04 DETERMINATION OF SR-89 AND SR-90 IN ASHED SAMPLES (VEGETATION, FISH, ETC.

Principle of Method The sample with stable strontium and barium carriers added is leached in nitric acid and filtered. After filtration, filtrate Is reduced in volume by evaporation. The residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides. After a second strontium nitrate precipitation from 70%

nitric acid, the nitrates are dissolved in acid again with added yttrium carrier and are stored for ingrowth of yttrium-90. The yttrium is precipitated as hydroxide and separated from strontium with the strontium being in the supemate.

SR-06 Rev. 1, 08-05-04 DETERMINATION OF SR-89 AND SR-90 IN SOIL AND BOTTOM SEDIMENTS Principle of Method The sample with stable strontium and barium carriers added is leached in hydrochloric acid. After separation from calcium, the residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides. After a second strontium nitrate precipitation from 70% nitric acid, the nitrates are dissolved in acid again with added yttrium carrier and are stored for ingrowth of yttrium-90. The yttrium Is precipitated as hydroxide and separated from strontium with the strontium being in the supernate. Each fraction is precipitated separately as an oxalate (yttrium) and carbonate (strontium) and is collected on No.

SR-06 Rev, 1, 08-05-04 DETERMINATION OF SR-89 AND SR-90 IN SOIL AND BOTTOM SEDIMENTS Procedure

1. Weigh out 5 - 50 g sample into a I liter beaker depending on the required LLD. Add ImL of strontium carrier and lmL of Ba carrier.

2. Stir mechanically while slowly adding 200mL of 6N HCI (It may be necessary to add a few drops of octyl alcohol to prevent excessive frothing.) Continue stirring for about 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. Allow a minimum of two hours for the insoluble material to settle.

3. Stir the mixture and filter with suction through a 24cm Whatman No. 42 filter paper using a Buchner funnel. Wash the residue with hot water. Wash with 6N HCI and again with hot water until the yellow color of ferric chloride is removed. Discard the residue.

4. Transfer the filtrate to a 1 liter beaker and evaporate to approximately 200mL. Cool and slowly add 200mL of concentrated HNO 3 . (If there is excessive frothing, add a few drops. of octyl alcohol.)

Evaporate to 100-200mL.

5. Add 500mL of water and stir.

6. Add 25 grams of oxalic acid with magnetic stirring until it is completely dissolved.

7. Adjust the pH to 5.5-6.0 with concentrated NH4 OH. (if the brown color of ferric hydroxide persists, add more oxalic acid and readjust.the pH.) The optimum condition Is an excess of oxalic acid in solution without causing crystallization of ammonium oxalate upon cooling.

8. Allow precipitate to settle for 5-6 hours or overnight.

9. Decant most of the supemate (liquid) and transfer the precipitate to a 250mL centrifuge tube using deionized water for rinsing. Add rinsing to the tube. Centrifuge and decant supernate.

10. Wash the precipitate with 50-1OOmL portion of water and centrifuge again.

11. Repeat washing as needed until all the yellow color of the solution has been removed.

12. Cool the precipitate and dissolve it with 6N HNO 3 and transfer it into a 250mL beaker. Rinse the tube with6N HNO 3, making the total volume to 50-100 mL. Add about 6 drops of H20 2 (30%) to facilitate dissolution.

13. Cool to room temperature. If insoluble material is present at this point, filter by suction through a glass fiber filter. Discard the filter and residue.

14. Transfer the solution to an appropriate size beaker and evaporate to dryness. The evaporation must be done slowly to avoid spattering.

15. Dissolve the salt in water and ,perform successive fuming nitric acid separations (the first two separations at concentration slightly greater than 75%) until the strontium has been separated from the bulk of the calcium. Samples with a high calcium content will require five or more separations.

16. The volumes of 75% HNO 3 vary (fuming solutions may be changed as required by the mass of calcium present, keeping In mind that minimum volumes are always best.)

3

SR-06 Rev. 1, 08-05-04 Procedure (continued)

17. If calcium content is still thick, evaporate the solution to dryness and bake.

18. Dissolve the residue with 50mL boiling water and filter. Discard residue.

19. Evaporate the solution to dryness again.

20. Cool and dissolve the residue in a minimum amount of water and add 50 mL of fuming HNO 3.

21. Continue the fuming nitric acid separations until the strontium has been separated from the bulk of calcium.

22. Transfer the solution to a 40mL conical, heavy-duty centrifuge tube, Using a minimum of concentrated HNO 3 to effect the transfer. Cool the centrifuge tube in an ice bath for about. Centrifuge and discard the supernatant.

NOTE: The precipitateconsists of calcium, strontium, and barium-radiumnitrate.

The supernatantcontains part of the sample's calcium and phosphate content.

23. Add 30mL of concentrated HNO 3 to the precipitate. Heat in a hot water bath with stirring for about 10 minutes. Cool the solution in an ice bath, stirring for about 5 minutes. Centrifuge and discard the supematant.

NOTE: Additional calcium is removed from the sample. Nitrate precipitation with 70% HNO3 will afford a partialdecontaminationfrom soluble calcium, while strontium, barium, and radium are completely precipitated.

Separation of calcium is best at 60% HNO ; however, at 60% the precipitationof strontium is not complete. Therefore, it is common practice to precipitate (Sr(N03) 2 with 70% HNO3 which is the concentrationof commercially available 16N HNO3.

Most other fission products, induced activities, and actinides are soluble in concentrated HN0N 3, affording a good "gross"decontaminationstep from a wide spectrum of radionuclides.

The precipitationis usually repeatedseveral times.

24. Repeat Step 23 two (2) more times.

25. Dissolve the nitrate precipitate in about 20mL distilled water. Add 1mL of scavenger solution. Adjust the pH of the mixture to 7 with 6N NH4OH. Heat, stir, and filter through a Whatman No. 541 filter.

Discard the mixed hydroxide precipitate.

26. To the filtrate, add 5mL of ammonium acetate buffer. Adjust pH with 6N HNO 3 or NH4OH to pH 5.5.

NOTE: The pH of the solution at this point is critical.

Add dropwise with stirring lmL of 3N Na 2CrO4 solution, stir and heat in a water bath.

27. Cool and centrifuge. Decant the supernate into another 40mL centrifuge tube. (Save the precipitate for barium analysis if needed.)

29. Dissolve the precipitate in no more than 4mL of 6N HNO 3. Add 20-30mL of fuming HNO 3 , cover with parafilm, cool in a water bath, and centrifuge. Decant and discard the supemate.

30. Repeat Step 13. RECORD THE TIME AND DATE AS THE BEGINNING OF YTTRIUM-90 INGROWTH.

31. Dissolve precipitate in 4mL of 6N HNO 3 and add lmL of yttrium carrier solution.

32. Cover with parafilm and store for 7-14 days.

NOTE: At this point, the sample can be transferredto a glass scintillation vial for the ingrowth storage.

Use severalportions of 6N HNO 3 (a total of not more than 4mL); then add lmL ofyttrium carrierto the vial.

Separation NOTE: If the sample was stored in the scintillation vial, transferback into 4OmL centrifuge tube using a few drops of 6N HNO3 as a rinse.

SR-07 Reissue, 08-05-04 DETERMINATION OF SR-89 AND SR-90 IN MILK (ION EXCHANGE BATCH METHOD)

Principle of Method A citrate complex of strontium carrier at the pH of milk is added to the milk sample. Strontium, barium, and calcium are absorbed on the cation-exchange resin.

Strontium, barium, and calcium are eluted from the cation-exchange resin with sodium chloride solution.

Following dilution of the eluate, the alkaline earths are precipitated as carbonates. The carbonates are then converted to nitrates. Strontium is purified by Argonhe method using three grams of extraction material in a chromatographic column. Yttrium carrier is added and a sample is stored for ingrowth of yttrium-90. The yttrium is again precipitated as hydroxide and separated from strontium with the strontium being in the supemate. Each fraction is precipitated separately as an oxalate (yttrium) and carbonate (strontium) and collected on No. 42 (2.4 cm) Whatman filter for counting.

The concentration of Sr-89 is calculated as the. difference between the activity for "total radiostrontium" and the activity due to Sr-90.

Reagents Ammonium hydroxide, NH 4OH: concentrated (15N)

Carrier solutions:

77 - +2 Sr as strontium nitrate, St(NO 3) 2: 20mg Sr per mL Y+3 as yttrium nitrate, Y(NO 3)3 : 10 mg Y 3 per mL Cation-exchange resin: Dowex 50W-X8 (Na+ form, 50-100 mesh)

6. Gently decant and discard the milk sample, taking care to retain as much resin as possible in the beaker. Add approximately 1 liter of deionized water to rinse the resin, allow to settle 2 minutes, and pour off the rinse. Repeat rinsing until all traces of milk are removed from the resin.

7. Using a DI water wash bottle, transfer the resin to the column marked with the sample number.

Allow resin to settle 2 minutes and drain the standing water.

8. Connect 1-liter separatory funnel containing I liter of 4N NaCI to the cation column. Allow solution to flow at 10 mL/minute to elute the alkali metal and alkaline earth ions and to recharge the column.

Collect I liter of eluate into a 2-liter beaker, but leave the resin covered with 2-3 mL of solution.

9. Wash the column with 500 mL of H20 or more to remove excess NaCI. Discard the wash.

10. Remove 20 mL of the NaCl eluate into a small bottle for the determination of stable calcium, if required (see procedure on calcium determination).

11. Dilute the eluate to 1500 mL with DI water.

EIML-T-02 Revision 5, 01-29-02 DETERMINATION OF TRITIUM IN WATER (DIRECT METHOD)

Principle of Method The water sample Is purified by distillation, a portion of the distillate Is transferred to a counting vial and the scintillation fluid added. The contents of the vial are thoroughly mixed and counted in aliquot scintillation counter.

Reagients Scintillation medium, Ultima-Gold LLT, Packard Instruments Co.

Tritium standard solution Dead water Ethyl alcohol Sodium Hydroxide (pellets)

Potassium permanganate (crystals)

Apparatus Condenser Distillation flask, 250-mL capacity Liquid scintillation counter Pipette and disposable tips (0.1ml., 5-10 ml.)

Kimwipes Procedure NOTE: All glassware must be dry. Set drying oven for 100-125°C.

1. Place 60-70 mL of the sample in a 250-mL distillation flask. Add a boiling chip to the flask. Add one NaOH pellet and about 0.02g KMnO4. Connect a side arm adapter and a condenser to the outlet of the flask. Place a receptacle at the outlet of the condenser. Set variac at 70 mark. Heat to boiling to distill. Discard the first 5-10mL of distillate. Collect next 20-25mL of distillate for analysis. Do not distill to dryness.

2. Mark the vial caps with the sample number and date.

NOTE: Use the same type of vial for the whole batch (samples, background and standard.)

3. Mark three vial caps "BKG-1"," BKG-2", "BKG-3", and date.

4. Mark three vial caps "ST-i", "ST-2"," ST-3"; standard number, and date.

5. Dispense 13 mL of sample into marked vials and "dead" water into vials marked BKG-1, BKG-2, BKG-3.

NOTE 1: The Pipette Is set (and calibrated) to deliver 6.5 mL, so pipette twice into each vial.

Use new tip for each sample and new tip (one) for three background samples.

NOTE 2: Make sure the pipette has not been reset. If It has been reset, or if you are not sure, do not use it; check with your supervisor.

NOTE 3: Make sure the plastic tip is pushed all the way on the pipette and is tight. If it is not, the air will be draw in and the volume withdrawn will not be correct (it will be smaller).

2

EIML-T-02 Revision 5, 01-29-02

6. Dispense 13 mL (see Notes 1, 2, and 3, above) of "dead" water into each vial marked "ST-l",

"ST-2" and "ST-3."

7. Using a 0.1 mL pipette, withdraw water from each of the three standard vials. Discard this 0.1 mL of water.

8. Take a new 0.1 mL tip. Dispense 0.1 mL of standard into each of the three vials marked "ST-l,"

"ST-2," and "ST-3."

9. Take all vials containing samples, background, and standard to the counting room.

NOTE: To avoid spurious counts, scintillation fluid should not be added under fluorescent light.

10. Dispense 10 mL of scintillation fluid into each vial (one at a time), cap tightly, and shake VIGOROUSLY for at least 30 seconds. Recheck the cap for tightness.

11. Wet a Kimwipe with alcohol and wipe off each vial in the following order:

Background

Samples Standard

12. Load the vials in the following order:

BKG-1 ST-I Samples BKG -2* *BKG-2 and ST-2 should be approximately ST -2* in the middle of the batch Samples BKG-3 ST -3

13. Let the vials dark- and temperature-adapt for about one hour.

NOTE 1: To check if vials have reached counter temperature, inspect one vial (Bkg). The liquid should be transparent. If the temperature is too high (or too low), the liquid will be white and very viscous.

NOTE 2: The temperature inside the counter should be between 100 and 14=C (check thermometer). In this temperature range, the liquid is transparent.

14. Set the counter for 100-minute counting time and infinite cycles. (Follow manufacturers procedure for setting the counter.)

3

EIML-T-02 Revision 5, 01-29-02

15. Fill out the loading sheet, being sure to indicate the date and time counting started, and your initials.

NOTE 1: Do not count prepared background and standard sets with another batch of samples If plastic vials are used. Prepare new backgrounds and standards for each batch.

NOTE 2: If glass vials are used, the prepared background and standard sets can be counted with other batches up to one month after preparation, provided they are not taken out of the counter (not warmed up) and the same vial type from the same manufacturing batch (the same carton) is used. After one month prepare new sets of backgrounds and standards.

DETERMINATION OF GROSS ALPHA ANDIOR GROSS BETA IN WATER a

(Dissolved Solids or Total Residue)

Principle of Method Water samples containing suspended matter are filtered through a membrane filter and the filtrate is analyzed. The filtered water sample Is evaporated and the residue is transferred to a tared planchet for counting gross alpha and gross beta activity.

Reagents All chemicals should be of "reagent-gradeu or equivalent whenever they are commercially available.

Lucite: 0.5 mg/ml in acetone Nitric acid, HNO3: 16 N (concentrated), I N (62 ml ofN HNO 8 diluted to I liter)

Apparatus Filter, membrane Type AA, 0.08 Filtration equipment Planchets (Standard 2"x1/8" stainless steel , ringed planchet)

Electric hotplate Heat lamp Drying oven Muffle furnace Analytical Balance Dessicator Proportional counter 2

W(DS)-01 Reissue, 07-23-04 Procedure

1. Filter a volume of sample containing not more than 100 mg of dissolved solids for alpha assay, or not more than 200 mg of dissolved solids for beta assay.-a NOTE: For gross alpha and gross beta assay in the same sample, limit the amount of solids to 100 mg.

2. Filter sample through a membrane filter. Wash the sides of the funnel with deionized (D. I.)

water. Discard the filter, unless determining suspended solids also. See procedure W(SS-)02.

3. Evaporate the filtrate to NEAR dryness on a hot plate.

4. Add 20 ml of concentrated HNO 3 and evaporate to NEAR dryness again.

NOTE: If a water samples is known or suspected to contain chloride salts, these salts should be converted to nitrates before the sample residue is transferred to a stainless steel planchet.

(Chldrides will attack stainless steel and increase the sample solids. No correction can be made for these added solids.) Chloride salts can be converted to nitrate salts by adding concentrated HN0 3 and evaporating to near dryness.

5. Transfer quantitatively the residue to a TARED PLANCHET, using an unused plastic -

disposable pipette for each sample,. (not more than I or 2 ml at a time) evaporating each portion to dryness under the lamp. Spread residue uniformly on the planchet.

NOTE: Non-uniformity of the sample residue in the counting planchet interferes with the accuracy and precision of the method.

6. Wash the beaker with DI water several times and combine the washings and the residue in the .

planchet, using the rubber policeman to wash the walls. Evaporate to dryness.

NOTE: Rinse the rubber policeman with DI water between samples.

7. Bake in muffle furnace at 400° C for 45 minutes, cool and weigh.

NOTE: If the sample is very powdery, add a few drops (6-7) of the Lucite solution and dry under the infrared lamp for 10-20 minutes.

8. Store the sample in a dessicator until ready to count since vapors from the moist residue can damage the detector and the window and can cause erratic measurements.

9. Count the gross alpha and/or the gross beta activity in a low background proportional counter.

NOTE: If the gas-flow internal proportional counter does not discriminate for the higher energy alpha pulses at the beta plateau, the activity must be subtracted from the beta plus alpha activity. This is particularly important for samples with high alpha activity.

Samples may be counted for beta activity immediately after baking; alpha counting should be delayed at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> (until equilibrium has occurred).

a For analysis of total residue (for clear water), proceed as described above but do not filter the water.

Measure out the appropriate amount and proceed to Step 3.

Figure 1 Environmental Sampling Location Rev. 10 i April 4, 2006

1.0 Introduction 1.1 Purpose The purpose of this document is to define the Radiological Environmental Monitoring Program (REMP) for the Kewaunee Power Station (KPS). The REMP is required by KPS 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 10CFR 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 Power Station so as to:

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

2. Serve as a gauge of the operating effectiveness of in-plant control of waste discharges; and

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 KPS 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 TS Amendment No. 64, which provided Radiological Effluent Technical Specifications (RETS) for KPS.

The REMP is setup to be implemented by a vendor and controlled by KPS in accordance with Nuclear Administrative Directive NAD-1.20, "Radiological Environmental Monitoring Program." Monthly reviews of the vendor's progress report are checked and approved by KPS in accordance with Surveillance Procedure SP-63-276. Annual reviews and submittals of the vendor's report and raw data are checked and approved by KPS 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 Rev. 10 1-1 April 4,2006

performed by KPS. Current vendor Quality Control Program Manuals and implementing procedures shall be kept on file at KPS.

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 KPS.

I 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 the REMP.

Rev. 10 1-2 April 4, 2006

2.0 REMP Requirements KPS TS Amendment No. 104 implemented the guidance provided in Generic Letter 89-01, I "Implementation of Programmatic Controls for Radiological Effluent Technical Specifications (RETS)." These changes included:

1. Incorporation of programmaticcontrols in the Administrative Controls section of the TS to satisfy existing regulatory requirements for RETS, and

2. Relocation of the procedural details on radioactive effluents monitoring, radiological environmental monitoring, reporting details, and other related specifications from the TS to the ODCM.

Relocating the procedural details to theODCM allows for revising these requirements using the 10CFR50.59 process instead of requiring prior NRC approval using the TS Amendment process.

The RETS requirements were incorporated verbatim into the ODCM, 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 KPS RETS section and then relocated into Revision 6 of the ODCM, as discussed above. These I 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, and 2.2.3 respectively)

Rev. 10 2-1 April 4, 2006

and an associated surveillance requirement (numbered 2.3.1, 2.3.2, and 2.3.3 respectively), along with the basis for the requirement. Reporting requirements are listed in specification REMM 2.4. 1.

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 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 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 REMIM 2.4.1 will be initiated.

SURVEILLANCE REQUIREMENTS 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 OPERABILIT 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.

Rev. 10 2-2 April 4, 2006

REMM 2.2.1/2.3.1 MonitoringProgram SPECIFICATION 2.2.1 The radiological environmental monitoring program shall be conducted as specified in Table 2.2.1-A.

APPLICABILITY At all times.

ACTION

a. With the radiological environmental monitoring program not being conducted as specified in Table 2.2. 1-A, in lieu of a Licensee Event Report, prepare and submit to the Commission, in the Annual Radiological Environmental Monitoring Report required by TS 6.9.b.1 and REMM 2.4.1, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence.

b. With the level of radioactivity as the result of plant effluents in an environmental sampling medium at a specified location exceeding the reporting levels of Table 2.2. 1-D when averaged over any calendar quarter in lieu of a Licensee Event Report, prepare and submit to the Commission within 30 days, pursuant to TS 6.9.b.3, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce radioactive effluents so that the potential annual dose' to A MEMBER OF THE PUBLIC is less than the calendar year limits of specifications ODCM 3.3.2, 3.4.2, and 3.4.3. When more than one of the radionuclides in Table 2.2. 1-D are detected in the sampling medium, this report shall be submitted if:

concentration(1) concentration(2) 1.0 reportinglevel (1) reportinglevel (2)

When radionuclides other than those in Table 2.2. 1-D are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose' to a MEMBER OF THE PUBLIC is equal to or greater than the calendar year limits of specifications ODCM 3.3.2, 3.4.2, and 3.4.3. This report is not required if the measured level of radioactivity was not the result of plant effluents; however, in such an event the condition shall be reported and described in the Annual Radiological Environmental Monitoring Report.

'The methodology and parameters used to estimate the potential annual dose to a member of the public shall be indicated in this report.

Rev. 10 2-3 April 4, 2006

c. With milk or fresh leafy vegetable samples unavailable from one or more of the sample locations required by Table 2.2.1-A, a sample from an alternative location will be substituted, noting the reason for the unavailability in the Annual Radiological Environmental Monitoring Report. When changes in sampling locations are permanent, the sampling schedule in the RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL (REMM) will be updated to reflect the new routine and alternative sampling locations and this revision will be described in the Annual Radiological Environmental Monitoring Report.

Rev. 10 2-4 April 4, 2006

SURVEILLANCE REQUIREMENT 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.

BASIS 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 10CFR Part 50 and 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.

The required detection capabilities for environmental sample analyses are tabulated in terns 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 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.

Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, J.K., "Detection Limits for Radioanalytical Counting Techniques,"

Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

Discussion KPS TS 6.16.b.2(a) requires that the monitoring, sampling, analysis, and reporting of radiation and -

radionuclides in the environment be done in accordance with the methodology and parameters in the ODCM.

Rev. 10 2-5 April 4, 2006

REMM 2.2.2/2.3.2 Land Use Census SPECIFICATION 2.2.2 A land use census shall be conducted and shall identify within a distance of 8 km (5 miles) the location in each of the 10 meteorological sectors of the nearest milk 2

animal, the nearest residence and the nearest garden 2 of greater than 50 m (500 fe) producing broad leaf vegetation.

APPLICABILITY At all times.

ACTION

a. With a land use census identifying a location(s) that yields a calculated dose or dose commitment greater than the values currently being calculated in specification ODCM 4.4.3, in lieu of a Licensee Event Report, identify the new location(s) in the next Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b.1 and REMM 2.4.1.

b. With a land use census identifying a location(s) that yields a calculated dose or dose commitment (via the same exposure pathway) 20% greater than at a location from which samples are currently being obtained in accordance with specification REMM 2.2.1, add the new location(s) to the radiological environmental monitoring program within 30 days. The sampling location(s), excluding the control station location, having a lower calculated dose or dose commitment(s), via the same exposure pathway, may be deleted from this monitoring program. In lieu of a Licensee Event Report, identify the new location(s) in the next Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b. 1 and REMM 2.4.1 and also include in the report a revised figure(s) and table for the REMM reflecting the new location(s).

SURVEILLANCE REQUIREMENT 2.3.2 The land use census shall be conducted during the growing season once per 12 months using reasonable survey methods, such as by a door-to-door survey, aerial survey, or by consulting local agriculture authorities. The results of the land use census shall be included in the Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b. 1 and REMM 2.4.1.

2Sampling of leaf vegetation may be performed at the site boundary in each of two different direction sectors with the highest predicted D/Qs in lieu of the garden census. Specifications for broad leaf vegetation sampling in Table 2.2.1-A item 4c shall be followed, including analysis of control samples.

Rev. 10 2-6 April 4, 2006

BASIS This specification is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the radiological environmental monitoring program are made if required by the door-to-door survey, from aerial survey or from consulting with local agricultural authorities. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR Part 50. Restricting the census to gardens of greater than 50 m 2 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/yr) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made:

1. 20% of the garden was used for growing leafy vegetation (i.e., similar to lettuce and cabbage), and

2. A vegetation yield of 2 kg/mi.

Discussion KPS TS 6.16.b.2(b) requires that a land use census be performed to ensure that changes in the use of I areas at and beyond site boundary are identified and that modifications to the radiological environmental monitoring program are made if required by the results of this census.

Rev. 10 2-7 April 4, 2006

REMM 2.2.3/2.3.3 InterlaboratoryComparisonProgram SPECIFICATION 2.2.3 Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program that has been approved by the Commission.

APPLICABILITY At all times.

ACTION

a. With analyses not being performed as required above, report corrective actions taken to prevent a recurrence to the Commission in the Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b.1 and REMM 2.4.1.

SURVEILLANCE REQUIREMENT 2.3.3 The Interlaboratory Comparison Program shall be described in the REMM. A summary of the results obtained as part of the above required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b.1 and REMM 2.4.1.

BASIS The requirement for participation in an approved Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of measurements of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR Part 50.

Discussion KPS TS 6.16.b.2(c) requires participation in an approved Interlaboratory Comparison Program to ensure that an independent check is performed of the precision and accuracy of radioactive materials measurements.. This will demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR Part 50.

Rev. 10 2-8 April 4, 2006

REMM 2.4.1 ReportingRequirements 2.4.1 The Annual Radiological Environmental Monitoring Report shall include:

a. Summaries, interpretations, and an analysis of trends of the results of the radiological environmental surveillance activities for the report period, including a comparison with pre-operational studies, with operational controls as appropriate, and with previous environmental surveillance reports, and an assessment of the observed impacts of the plant operation on the environment. The reports shall also include the results of land use censuses required by specification REMM 2.2.2.

b. The results of analyses of radiological environmental samples and of environmental radiation measurements taken during the period pursuant to the locations specified in the table and figures in the Radiological Environmental Monitoring Manual (REMM), as well as summarized and tabulated results of these analyses and measurements in the format of the table in the Radiological Assessment Branch Technical Position, Revision 1, November 1979. In the event that some individual results are not available for inclusion with the report, the report shall be submitted noting and explaining the reasons for the missing results. The missing data shall be submitted as soon as possible in a supplementary report when applicable.

c. A summary description of the radiological environmental monitoring program; legible maps covering all sampling locations keyed to a table giving distances and directions from the centerline of one reactor; the results of licensee participation in the Interlaboratory Comparison Program, required by specification REMM 2.2.3; discussion of all deviations from the sampling schedule of Table 2.2.1-A; and discussion of all analyses in which the LLD required by Table 2.3.1-A was not achievable.

Discussion KPS TS 6.9.b.1 provides the programmatic control, which requires that an Annual Radiological I Environmental Monitoring Report be submitted to the NRC. It also states that this report shall include summaries, interpretations, and analysis of trends of the results of the REMP for the reporting period.

The procedural details of this report are included in this specification. Specifications REMM 2.2.1/2.3.1, 2.2.2/2.3.2, and 2.2.3/2.3.3 also include specific reporting requirements. These specifications reference this REMM specification, along with TS 6.9.b. 1, as the method for reporting deviations from the current program during the reporting period, and require that this information be included in the Annual Radiological Environmental Monitoring Report.

Rev. 10 2-9 April 4, 2006

3.0 REMP Implementation The Radiological Environmental Monitoring Program for KPS is under the direction of a Contracted Vendor (CV). This section describes this program, as required by REMM 2.2.1 and the process the CV uses to perform it.

3.1 Sampling Requirements Table 2.2.1-A identifies the various samples required by the REMP. Identified in the "available sample locations" column in Table 2.2.1-A are the sample locations selected, in conjunction with the vendor, to meet or exceed the REMP requirements. Table 2.2.1-B includes the same requirements as in Table 2.2.1-A but presents the information in a different format by identifying the type of samples required at each location and the collection frequency. Table 2.2.1-C identifies the location and description of each sample location. Figure 1 shows the physical location of each sample point on an area map.

3.2 Analysis Methodology Analytical procedures and counting methods employed by the CV will follow those recommended by the U.S. Public Health Service publication, Radioassay Procedures for Environmental Samples, January 1967; and the U.S. Atomic Energy Commission Health and Safety Laboratory, HASL Procedures Manual (HASL-300), 1972. The manual is also available on-line at www.eml.doe.gov/publications/procman.

Updated copies will be maintained in KPS's vault.

3.3 Detection Capability (LLD) Requirements The required detection capabilities for environmental sample and analysis are tabulated in terms of lower limits of detection (LLDs) in Table 2.3.1-A. 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 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.

Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem. 40,586-93 (1968), and Hartwell, J.K., "Detection Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

Rev. 10 3-1 April 4, 2006

3.4 ContractedVendor Reporting Requirements Monthly ProgressReports Monthly progress reports will include a tabulation of completed analytical data on samples obtained during the previous 30 day period together with graphic representations where trends are evident, and the status of field collections. One copy of the reports will be submitted within 30 days of the reporting month.

Annual Reports Annual reports will be submitted in two parts. Part I, to be submitted to the NRC, will be prepared in accordance with NRC Regulatory Guide 4.8. It will contain an introductory statement, a summary of results, description of the program, discussion of the results, and summary table. Part I1of the annual report will include tables of analytical data for all samples collected during the reporting period, together with graphic presentation where trends are evident and statistical evaluation of the results. Gamma scan data will be complemented by figures of representative spectra. Draft copies of each annual report will be due 60 days after completion of the annual period. After final review of the draft document, one photoready copy of the revised annual report will be sent to KPS for I, printing.

Non-Routine Reports If analyses of any samples collected show abnormally high levels of radioactivity, KPS will be notified by telephone immediately after data becomes available.

Action Limits The CV will report any radioactive concentrations found in the environmental samples which exceed the reporting levels shown in Table 2.2.1-D, CV to KPS column. These levels are set below the NRC required reporting levels (KPS to NRC column) so actions can be initiated to prevent exceeding the NRC concentration limits.

3.5 Quality ControlProgram To insure the validity of the data, the CV maintains a quality control (QC) program, which employs quality control checks, with documentation, of the analytical phase of its environmental monitoring studies. The program is defined in the CV's QC Program Manual, and procedures are presented in the CV QC Procedures Manual. The program shall be reviewed and meet the requirements of Regulatory Guide 4.15 and 10CFR21. All data related to quality control will be available for review by Dominion Energy Kewaunee upon reasonable prior notification. Proprietary information will be identified so that it may be treated accordingly.

Updated copies of the Quality Control Program Manual and the Quality Assurance Program Manual will be maintained in KPS's vault.

Rev. 10 3-2 April 4, 2006

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

Airborne Particulates Airborne particulates are collected at six locations (K-lf, K-2, K-7, K-8, K-16, K-31) on a continuous basis on a 47 mm diameter membrane filter of 0.8 micron porosity at a volumetric rate of approximately one cubic foot per minute (CFM). The filters are changed weekly, placed in glassine protective envelopes, and dispatched by U.S. Mail to the CV for Gamma Isotopic Analysis.

Filter samples are analyzed weekly for gross beta activity after sufficient time (usually 3 to 5 days) has elapsed to allow decay of Radon and Thoron daughters. If gross beta concentration in air particulate samples are greater than ten (10) times the yearly mean of the control samples, gamma isotopic analysis shall be performed on the individual samples. Quarterly composites from each location receive Gamma Isotopic Analysis using a Germanium detector. All identifiable gamma-emitters are quantified. Reporting units are pCi/rn 3.

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

Periphyton (Slime) orAquatic Vegetation Periphyton (slime) or aquatic plant samples are collected at or near locations used for surface water sampling. They are collected twice during the year (2nd and 3rd quarter), if available. The samples are analyzed for gross beta activity and, if available in sufficient quantity, for Sr-89, Sr-90, and by Gamma Isotopic Analysis. Reporting units are pCi/g wet weight.

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

Domestic Meat Domestic meat (chickens) may be collected once a year during the 3rd quarter, from six locations in the vicinity of the plant (K-20, K-24, K-27, K-29, K-34, and 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 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.

Rev. 10 3-3 April 4, 2006

Ambient Radiation Two packets of thermoluminescent dosimeters (CaS 04: Dy cards) are placed at forteen locations, six of which are air sampling locations (K-If, K-2, K-7, K-8, K-16, and K-31) and four of which are milk sampling locations (K-3, K-5, K-25, and K-39); the remaining four locations are K -15, K-17, K-27, and 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 moisture each set of cards is sealed in a plastic bag and placed in a plastic container. --

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 (1 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 1 standard deviation.

Reporting units for TLDs are mR/91 days for quarterly TLDs and mR/exposure period for annual TLDs.

Tests for uniformity and reproducibility of TLDs as specified in ANSI N545-1981 and NRC Regulatory Guide 4.13, are performed annually.

Well Water One gallon water samples are taken once every three months from four off-site wells, (K-10, K-11, K-13, and K-25) and two on-site wells (K-lh and K-lg). All samples are analyzed for gross beta in the total residue, K-40, tritium, and by Gamma Isotopic Analysis. Samples from one on-site well are analyzed for Sr-89, and Sr-90. 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-11. This sample is analyzed for tritium. Reporting units are pCi/l.

Milk Milk samples are collected from two herds that graze within three miles of the reactor site (K-25 and K-34); from four herds that graze between 3-7 miles of the reactor site (K-3, K-5, K-38, and K-39);

and 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 Rev. 10 3-4 April 4, 2006

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 137Cs/gK and 9°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 six dairy farms (K-3, K-5, K-25, K-34, K-38, and.K-39) and from two on-site 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 six 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. If samples are not available from these locations, samples may be obtained from any local source so there is some sample of record. The location will be documented. In addition, two varieties of grain, if available, are collected annually from the farmland owned by Dominion Energy Kewaunee (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.

Eggs Quarterly samples of eggs can be taken from K-24, K-27, and 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, 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 six dairy farms and from an on-site location (K-If). 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.

Rev. 10 3-5 April 4, 2006

Surface Water Surface water is sampled monthly from Lake Michigan at the KPS 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 I

Bay Municipal Pumping station between Kewaunee and Green Bay (K-9). Raw and treated water 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-lk) 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, 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-ld), 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 semi-annually (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.

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 2.2.1-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 if 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 Rep6rt. It is recognized that, 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 Report.

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.

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

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

g. The "upstream sample" shall be taken at a distance beyond significant influence of the discharge. The "downstream" sample shall 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.

Table Notationsfor Table 2.3.1-A

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.

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

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 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:

LLD =

E x V x 2.22 x Y x exp(--yAt)

Where:

LLD is the a priori lower limit of detection as defined above, as picocuries per unit mass or volume, Sb is the standard deviation of the background counting rate or of the counting rate of blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, 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, Typical values of E, V, Y, and At should be used in calculation.

Rev. 10 Page 2 of 3 April 4, 2006

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/i may be used.

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

Nimber:

PART I: Describe the Proposed Activity and Search the KNPP USAR (Refer to NMC 50.59 Resource Manual Section 5.3.1) 1.1. Describe the proposed activity, and scope of the activity covered by this screening. Appropriate descriptive materials may be attached.

Revision 10 to the REMM is removing the reference requiring the analytical vendor to have a QA program that is compliant with 10 CFR 50 Appendix B and replace this with Regulatory Guide 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operations) -- Effluent Streams and the Environment.

1.2. Search the Updated Safety Analysis Report (USAR) including those documents incorporated by reference. Describe relevant function(s), performance requirements, and methods of evaluation of the affected SSCs, and where this information is described in the USAR. In general, any USAR information potentially affected by the activity should be identified (consider both support functions and indirect affects). It is acceptable to attach and highlight applicable portions of the USAR.

USAR Sections 2.8, Environmental Radioactivity Program, 11.1.3, Design Evaluation, and 11.2.3 Radiation Monitoring System were reviewed. These sections each reference either the REMM or the ODCM. None discuss quality assurance methods that are acceptable for performance of an Environmental Monitoring Program (ODCM and REMM). These sections indicate that the ODCM and REMM define the necesssary controls for the program.

The REMM, under section 3.5, Quality Control Program4, states, 'To insure the validity of the data, the CV [Contracted Vendor] maintains a quality control (QC) program, which employs quality control checks, with documentation, of the analytical phase of its environmental monitoring studies. The program is defined in the CV's QC Program Manual, and procedures are presented in the CV QC Procedures Manual. The program shall be reviewed and meet the requirements of 10CFR50 Appendix B and 10CFR21."

1.3. Does the activity involve a change to the Technical Specifications?

10 CFR 50.59 Screening #06-014-00 Attachment 1 Pagel of 2 The following is provided as the basis for the conclusions relative to Part II, questions 1 through 8:

1. NO - The proposed change in the quality assurance requirements that must be met by the Kewaunee Power Station (KPS) Radiological Environmental Monitoring Manual (REMM) specified contracted vendor does not involve either the Safety Analysis or an SSC credited in the Safety Analysis.

2. NO - There is no SSC that supports an SSC credited in the Safety Analysis that is involved with the proposed change in the quality assurance requirements that must be met by the contracted vendor specified in the KPS REMM.

3. NO - The proposed change in the quality assurance requirements that must be met by the KPS REMM specified contracted vendor does not involve any SSCs whose failure could initiate a transient or accident.

4. NO - There are no SSCs whose failure could impact SSCs credited in the Safety Analysis that are involved with this proposed change in the quality assurance requirements that must be met by the contracted vendor specified in the KPS REMM.

5. YES - This proposed change does involve changing a program specified quality assurance requirement contained in the KPS REMM, from 10 CFR 50 Appendix B to Regulatory Guide 4.15.

6. NO - The proposed change in the quality assurance requirements that must be met by the KPS REMM specified contracted vendor does not involve a method of evaluation described in the USAR.

7. NO - This proposed change in the quality assurance requirements that must be met by the KPS REMM specified contracted vendor is neither a test nor an experiment.

8. NO - No design basis limit for a fission product barrier will be exceeded or potentially affected by this proposed change in the quality assurance requirements that must be met by the KPS REMM specified contracted vendor.

This activity is changing the existing program performance requirements as specified in the REMM (which is part of the KPS USAR as a document incorporated by reference).

The contracted vendor, as identified in the REMM, performs sample collection, analysis and reporting for the Environmental Monitoring Program.

10 CFR 50.59 Screening #06-014-00 Attachment 2 Page Iof 1 The following is provided as the basis for the conclusions relative to Part II. 1, questions a through d:

a. NO - A change to the quality assurance standard the vendor is to implement does not change the expected performance or methods of performing sample collection, analysis, or reporting of environmental sampling. Therefore, this change is not adverse to any design functions identified in Part II.

b. NO - The Environmental Monitoring program does not interface with or provide any inputs to any active plant components, and also has no method of initiating an accident. Therefore, a change in the quality assurance program required to be implemented by the vendor will not introduce an accident of a different type.

c. NO - The Environmental Monitoring program does not interface with or provide any inputs to any active plant components, and has no method of creating a malfunction. Therefore, a change in the quality assurance program required to be implemented by the vendor will not introduce a malfunction.

d. NO - Regulatory guide 4.15 - 1979, Quality Assurance for Radiological Monitoring Programs (Normal Operations) -- Effluent Streams and the Environment, provides equivalent controls to 10 CFR 50 Appendix B, to the extent necessary for the activities completed in the REMM and ODCM. The Reg.

Guide specifically states in its introduction, "This guidance does not identify separately the activities that are within the scope of Appendix B to 10 CFR

50. However, this guidance is intended to be consistent with the requirements of Appendices A and B to 10 CFR 50 in that quality assurance requirements should be consistent with the importance of the activity."

The regulatory guide provides sections that are consistent with the following criteria from 10 CFR 50, App. B:

I, V, X, XI, XVII, and XVIII, with specific directions and considerations for the specific purpose of providing quality results for a Radiological Monitoring Program.

Based on the above, changing the required quality assurance standard that must be met by the vendor does not adversely affect the method of controlling the environmental monitoring program.

Kewaunee Power Station Dominion Operational Quality Assurance Date: 08/04/05 Program Description Rev. 22.b Page 17 of 40 2.0 QUALITY ASSURANCE PROGRAM 2.1 General The Operational Quality Assurance Program complies with the requirements of 10 CFR 50, Appendix B, the provisions of ANSI N18.7-1976 and the Regulatory Guides which endorse the daughter standards required by ANSI N18.7-1976 with the exceptions, interpretations, and qualifications noted in Appendix B of this description. The requirements of the OQAPD apply to those activities which affect the quality of structures, systems, or components that prevent or mitigate the consequences of postulated accidents that could cause undue risk to the health and safety of the public. All structures, systems, and components are classified as QA Type 1, 2, 3 or N according to their function and importance in relation to the safe operation of the reactor, with emphasis on the degree of integrity required to protect the public. The OQAPD requirements are mandatory for all QA Type 1 items.

QA Type 2 and 3 items, as determined by management, may require special control and an "X" modifier may be added to the QA2 or QA3 type designation. All components and/or systems which are identified as Nuclear Safety Design Class I in the Updated Safety Analysis Report (USAR) shall be categorized as QA Type 1.

All nuclear fuel and core components shall be categorized as QA Type 1. The definitions and a list of the Nuclear Safety Design Classes for major structures, systems and components are found in the Kewaunee USAR Appendix B.2 and Table B.2-1.

During construction, QA types were established for plant equipment by a QA typing committee. The QA types for equipment subsequently added to the plant are established by the Responsible Engineer who installs the equipment under the Plant Physical Change program. The Plant Physical Change program exists under the requirements of the OQAPD. Therefore, the QA types of equipment added since construction are controlled under the OQAPD and its definitions. A change to an established QA type must be approved by the QA Typing Committee.

Auxiliary Shielding The auxiliary shield consists of concrete walls around certain components and piping which process reactor coolant. .In some cases, the concrete block walls are removable to allow personnel access to equipment during maintenance periods. Each equipment compartment is individually shielded so those compartments may be entered without having to shut down the adjacent system for any reason.

The primary shield material provided throughout the Auxiliary Building is concrete. The principal auxiliary shielding provided and the original design parameters are tabulated in Table 11.2-6.

11.2.3 RADIATION MONITORING SYSTEM The Radiation Monitoring System provides continuous radiological surveillance of plant system and working areas. The system performs the following basic functions:

+ Warns operating personnel of radiological health hazards, such as abnormal radiation fields.

+ Provides warning of plant malfunctions, which could lead to* plant damage and/or radiological hazards.

+ Prevents or minimizes inadvertent releases of radioactivity to the environment via automatic action capability.

+ Provides monitoring of controlled radiological plant releases.

Radiation detection instruments are located in areas of the plant, which house equipment containing or processing radioactive fluid. These instruments continually detect, compute, and record operating radiation levels. If the radiation level should rise above the set point for any channel, an alarm is initiated in the Control Room or Radiation Protection Office. Some channels also alarm locally. In stipulated cases, the alarm signal also provides the necessary signal for automatic process controls (e.g., valve closure, damper isolation, etc.). The Radiation Monitoring System operates in conjunction with regular and special radiation surveys and with chemical and radiochemical analyses performed by the plant staff. Adequate information and warning is thereby provided for the continued safe operation of the plant and assurance that personnel exposure does not exceed the limits of 10 CER 20.

Two high range detectors are located in the containment. These two-containment area monitoring channels are the only components in the Radiation Monitoring System designed to operate following a major loss-of-coolant accident.

The components of the Radiation Monitoring System are designed according to the following environmental conditions:

• Temperature - an ambient temperature range as specified in Table 11.2-8.

+ Humidity - 0 to 95% relative humidity.

USAR - Rev. 19 11.2-7 06/0 1/2005

+ Pressure - Components in the Auxiliary Building and Control Room are designed for normal atmospheric pressure. Area Monitoring System components inside the Containment are designed to withstand containment test pressure.

+ Radiation - Process and area radiation monitors are of a non-saturating design so that they "peg" full scale if exposed to radiation levels at over full-scale intensities. Critical process monitors are located in areas where the normal and post-accident background radiation levels will not affect their usefulness. -

The Radiation Monitoring System consists of two types of components, the Process monitors and the Area monitors.

+ The Process Radiation Monitoring System refers to those radiation monitors capable of analyzing fluid (air or water) flow for indication of increasing radiation levels.

+ The Area Radiation Monitoring System monitors the direct radiation in various areas of the plant or indication of increasing radiation levels.

Main Process Radiation Monitoring System The Main Process Radiation Monitoring System is designed to provide information to plant personnel on:

+ Radioactivity levels present in fluid (air and water) systems.

+ Leakage across boundaries of closed systems.

+ Radioactivity concentrations in liquid and gaseous flow paths that lead to release from the plant.

In conjunction with the design functions spelled out above, the system is capable of initiating automatic actions designed to prevent or minimize any inadvertent/uncontrolled release of radioactivity to the environment.

The Main Process Monitoring System consists of 13 channels of monitoring equipment, 9 of, which are equipped with some level of automatic action upon receipt of a high radiation alarm. Seven of the 13 channels perform engineered safety related functions. The Main Process Monitoring System consists of the following:

Process Monitors

+ R-11 Containment System vent (Air Particulate)

• R-12 Containment System vent (Radioactivity Gas)

+ R-13 Auxiliary Building vent A USAR - Rev. 19 11.2-8 06/01/2005

Valves All valves exposed to gases are carbon steel. Those exposed to liquids are stainless steel. All valves have stem leakage control. Globe valves are installed with flow over the seats when such an arrangement reduces the possibility of leakage.

Isolation valves are provided to isolate each piece of equipment for maintenance, to direct the flow of waste through the system, and to isolate storage tanks for radioactive decay.

Relief valves are provided for tanks containing radioactive wastes to prevent overpressurization by improper operation or component malfunction. Tanks containing wastes, which are normally free of gaseous activity, are vented locally.

11.1.3 DESIGN EVALUATION The radiological impact of power uprate was evaluated for normal operation annual radwaste effluent releases (Reference 5).

Based on this evaluation it was determined that the power uprate to a core power level of 1772 MWt has no significant impact on the expected annual radwaste effluent releases/doses. All doses remain a small percentage of allowable 10CFR50 Appendix I dose limits. Following power uprate the liquid and gaseous radwaste effluent treatment system will remain capable of maintaining normal operation off-site doses within the requirements of IOCFR50 Appendix I (Reference 5).

Liquid Wastes Liquid Wastes are generated primarily by plant maintenance and service operations. Tables 11.1-4 and 11.1-5 contain a summary of the actual historical average annual values of the quantities and activity concentrations of influents to the system during the 1976 through 1981 time frame (which reflects plant operation at the average core power during that period). If the historical data is used to project the future release, core power uprate to 1772 MWt is expected to have minimal impact on the discharge quantities listed in Table 11.1-4.

However, the released radioactivity in Table 11.1-5 could potentially increase by the percentage increase in power level between the uprated conditions and the average core power level during that time period (Reference 4).

Gaseous Wastes Gaseous wastes consist primarily of hydrogen stripped from coolant discharged to the CVCS holdup tanks during boron dilution, nitrogen and hydrogen gases purged from the CVCS volume control when degassing the reactor coolant, and nitrogen from the Closed Gas Blanketing

'System. The original design basis for the gas decay tank capacity allows for storage of collected gaseous waste for at least 45 days prior to release. t e scifica!ioa are~contaier idn the, KNPOff-Site Dose Calcilatiori Manual (ODCM). Table 11.1-6 contains a summary of the USAR - Rev. 19 11.1-12 06/01/2005 0~~<

estimated annual average gaseous release from the plant. Based on the 1986 and 1987 KNPP Semi-Annual Effluent Release Reports, actual typical annual gaseous discharge activity has been averaging less than 25% of the values shown in Table 11.1-6. The values in Table 11.1-6 are representative of a core power level of 1650 MWt. With a core power uprate to 1772 MWt, the Table 11.1-6 values could potentially increase by a maximum of the percentage increase in power level (Reference 4).

Solid Wastes Solid wastes consist of filters, spent resins and miscellaneous materials such as paper and plastic. All solid wastes are packaged as noted under "Solids Processing" for removal to a burial facility. Annual solids, exclusive of solidified resins shipped for burial, averaged 1025 ft3 during the period between 1975 and 1981. Annual average spent resin quantities shipped are 740 ft. More recent solid waste shipments are consistent with or below these volumes.

11.1.4 MINIMUM OPERATING CONDITIONS Verification is made to ensure that dilution flow sufficient to meet the requirements of 10 CFR 20 is available whenever radioactive liquid wastes are released to the Plant Discharge System.

All liquid waste releases are continuously monitored for gross activity during discharges to ensure that the activity limits specified in 10 CFR 20 for unrestricted areas are not exceeded. The Off-Site Dose Calculation Manual provides guidance when continuous monitoring is unavailable.

All batch radioactive liquid wastes are sampled prior to release to the Plant Discharge System.

At least one Auxiliary Building normal mode ventilation fan is in operation whenever radioactive gaseous wastes are released to the Auxiliary Building vent.

The maximum allowable dose rates at the site boundary due to discharges are specified in the Off-Site Dose Calculation Manual.

A record is maintained of the radioactive material contained in all releases.

- f 1.0 Introduction 1.1 Purpose The purpose of this document is to define the Radiological Environmental Monitoring Program (REMP) for the Kewaunee Power Station (KPS). The REMP is required by KPS 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 10CFR 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 Power Station so as to:

I. Determine the effects of the operation of the Kewaunee Power Station on the environment;

2. Serve as a gauge of the operating effectiveness of in-plant control of waste discharges; and

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 KPS 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 TS Amendment No. 64, which provided Radiological Effluent Technical Specifications (RETS) for KPS.

The REMP is setup to be implemented by a vendor and controlled by KPS in accordance with Nuclear Administrative Directive NAD-1.20, "Radiological Environmental Monitoring Program." Monthly reviews of the vendor's progress report are checked and approved by KPS in accordance with Surveillance Procedure SP-63-276. Annual reviews and submittals of the vendor's report and raw data are checked and approved by KPS 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 Rev. 11 1-1 12/14/2006

performed by KPS. Current vendor Quality Control Program Manuals and implementing procedures shall be kept on file at KPS.

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 KPS.

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 the REMP.

Rev. 11 1-2 12/14/2006

2.0 REMP Requirements KPS 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 of programmaticcontrols in the Administrative Controls section of the TS to satisfy existing regulatory requirements for RETS, and

2. Relocation of the procedural details 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 10CFR50.59 process instead of requiring prior NRC approval using the TS Amendment process.

The RETS requirements were incorporated verbatim into the ODCM, 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 TechnicalSpecification 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 KPS 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, and 2.2.3 respectively)

Rev. 11 2-1 12/14/2006

and an associated surveillance requirement (numbered 2.3.1, 2.3.2, and 2.3.3 respectively), along with the basis for the requirement. Reporting requirements are listed in specification REMM 2.4.1.

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 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 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 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.

REMM 2.2.1/2.3.1 Monitoringprogram SPECIFICATION 2.2.1 The radiological environmental monitoring program shall be conducted as specified in Table 2.2.1-A.

APPLICABILITY At all times.

ACTION

a. With the radiological environmental monitoring program not being conducted as specified in Table 2.2.1-A, in lieu of a Licensee Event Report, prepare and submit to the Commission, in the Annual Radiological Environmental Monitoring Report required by TS 6.9.b.1 and REMM 2.4.1, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence.

b. With the level of radioactivity as the result of plant effluents in an environmental sampling medium at a specified location exceeding the reporting levels of Table 2.2.1-D when averaged over any calendar quarter in lieu of a Licensee Event Report, prepare and submit to the Commission within 30 days, pursuant to TS 6.9.b.3, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce radioactive effluents so that the potential annual dose' to A MEMBER OF THE PUBLIC is less than the calendar year limits of specifications ODCM 3.3.2, 3.4.2, and 3,4.3. When more than one of the radionuclides in Table 2.2.1-D are detected in the sampling medium, this report shall be submitted if:

c. With milk or fresh leafy vegetable samples unavailable from one or more of the sample locations required by Table 2.2.1 -A, a sample from an alternative location will be substituted, noting the reason for the unavailability in the Annual Radiological Environmental Monitoring Report. When changes in sampling locations are permanent, the sampling schedule in the RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL (REMM) will be updated to reflect the new routine and alternative sampling locations and this revision will be described in the Annual Radiological Environmental Monitoring Report.

Rev. 11 2-4 12/14/2006

'- I SURVEILLANCE REQUIREMENT 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. I-A.

BASIS 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 10CFR Part 50 and 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.

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 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.

Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, J.K., "Detection Limits for Radioanalytical Counting Techniques,"

Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

Discussion KPS TS 6.16.b.2(A) requires that the monitoring, sampling, analysis, and reporting of radiation and radionuclides in the environment be done in accordance with the methodology and parameters in the ODCM.

With a land use census identifying a location(s) that yields a calculated dose or dose commitment (via the same exposure pathway) 20% greater than at a location from which samples are currently being obtained in accordance with specification REMM 2.2.1, add the new location(s) to the radiological environmental monitoring program within 30 days. The sampling location(s), excluding the control station location, having a lower calculated dose or dose commitment(s), via the same exposure pathway, may be deleted from this monitoring program. In lieu of a Licensee Event Report, identify the new location(s) in the next Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b. 1 and REMM 2.4.1 and also include in the report a revised figure(s) and table for the REMM reflecting the new location(s).

SURVEILLANCE REQUIREMENT 2.3.2 The land use census shall be conducted during the growing season once per 12 months using reasonable survey methods, such as by a door-to-door survey, aerial survey, or by consulting local agriculture authorities. The results of the land use census shall be included in the Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b. 1 and REMM 2.4. 1.

2Samplingpof leaf vegetation may be performed at the site boundary in each of two different direction sectors with the highest predicted DIQs in lieu of the garden census. Specifications for broad leaf vegetation sampling in Table 2.2.1-A item 4c shall be followed, including analysis of control samples.

Rev. 11 2-6 12/14/2006

BASIS This specification is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the radiological environmental monitoring program are made if required by the door-to-door survey, from aerial survey or from consulting with local agricultural authorities. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR Part 50. Restricting the census to gardens of greater than 50 m2 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/yr) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made:

1. 20% of the garden was used for growing leafy vegetation (i.e., similar to lettuce and cabbage), and

2. A vegetation yield of 2 kg/m 2.

Discussion KPS TS 6.16.b.2(b) requires that a land use census be performed to ensure that changes in the use of areas at and beyond site boundary are identified and that modifications to the radiological environmental monitoring program are made if required by the results of this census.

REMM 2.2.3/2.3.3 InterlaboratoryComparison Program SPECIFICATION 2.2.3 Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program that has been approved by the Commission.

APPLICABILITY At all times.

ACTION

a. With analyses not being performed as required above, report corrective actions taken to prevent a recurrence to the Commission in the Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b. 1 and REMM 2.4.1.

SURVEILLANCE REQUIREMENT 2.3.3 The Interlaboratory Comparison Program shall be described in the REMM. A summary of the results obtained as part of the above required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Monitoring Report pursuant to TS 6.9.b. 1 and REMM 2.4.1.

BASIS The requirement for participation in an approved Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of measurements of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR Part 50.

Discussion KPS TS 6.16.b.2(c) requires participation in an approved Interlaboratory Comparison Program to ensure that an independent check is performed of the precision and accuracy of radioactive materials measurements. This will demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR Part 50.

Rev. 11 2-8 12/14/2006

t REMM 2.4.1 ReportingRequirements 2.4.1 The Annual Radiological Environmental Monitoring Report shall include:

Rev. 11 2-9 12/14/2006

3.0 REMP Implementation The Radiological Environmental Monitoring Program for KPS is under the direction of a Contracted Vendor (CV). This section describes this program, as required by REMM 2.2.1 and the process the CV uses to perform it.

3.1 Sampling Requirements Table 2.2.1-A identifies the various samples required by the REMP. Identified in the "available sample locations" column in Table 2.2.1-A are the sample locations selected, in conjunction with the vendor, to meet or exceed the REMP requirements. Table 2.2.1-B includes the same requirements as in Table 2.2.1-A but presents the information in a different format by identifying the type of samples required at each location and the collection frequency. Table 2.2.1-C identifies the location and description of each sample location. Figure 1 shows the physical location of each sample point on an area map.

3.2 Analysis Methodology Analytical procedures and counting methods employed by the CV will follow those recommended by the U.S. Public Health Service publication, Radioassav Procedures for Environmental Samples, January 1967; and the U.S. Atomic Energy Commission Health and Safety Laboratory, HASL Procedures Manual (HASL-300), 1972. The manual is also available on-line at www.eml.doe.gov/publications/procman.

Updated copies will be maintained in KPS's vault.

3.3 Detection Capability (LLD) Requirements The required detection capabilities for environmental sample and analysis are tabulated in terms of lower limits of detection (LLDs) in Table 2.3.1-A. 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 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.

Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, J.K., "Detection Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

Rev. 11 3-1 12/14/2006

3.4 ContractedVendor Reporting Requirements Monthly ProgressReports Monthly progress reports will include a tabulation of completed analytical data on samples obtained during the previous 30 day period together with graphic representations where trends are evident, and the status of field collections. One copy of the reports will be submitted within 30 days of the reporting month.

Annual Reports Annual reports will be submitted in two parts. Part I, to be submitted to the NRC, will be prepared in accordance with NRC Regulatory Guide 4.8. It will contain an introductory statement, a summary of results, description of the program, discussion of the results, and summary table. Part II of the annual report will include tables of analytical data for all samples collected during the reporting period, together with graphic presentation where trends are evident and statistical evaluation of the results. Gamma scan data will be complemented by figures of representative spectra. Draft copies of each annual report will be due 60 days after completion of the annual period. After final review of the draft document, one photoready copy of the revised annual report will be sent to KPS for printing.

Non-Routine Reports If analyses of any samples collected show abnormally high levels of radioactivity, KPS will be notified by telephone immediately after data becomes available.

Action Limits The CV will report any radioactive concentrations found in the environmental samples which exceed the reporting levels shown in Table 2.2. 1-D, CV to KPS column. These levels are set below the NRC required reporting levels (KPS to NRC column) so actions can be initiated to prevent exceeding the NRC concentration limits.

3.5 Quality ControlProgram To insure the validity of the data, the CV maintains a quality control (QC) program, which employs quality control checks, with documentation, of the analytical phase of its environmental monitoring studies. The program is defined in the CV's QC Program Manual, and procedures are presented in the CV QC Procedures Manual. The program shall be reviewed and meet the requirements of Regulatory Guide 4.15 and 10CFR2 1. All data related to quality control will be available for review by Dominion Energy Kewaunee upon reasonable prior notification. Proprietary information will be identified so that it may be treated accordingly.

Updated copies of the Quality Control Program Manual and the Quality Assurance Program Manual will be maintained in KPS's vault.

Rev. 11 3-2 12/14/2006

-.4 3.6 Sample Descriptions A description of each of the samples required by this program follows:

Airborne Particulates Airborne particulates are-collected at six locations (K-If, K-2, K-7, K-8, K-16, K-31) on a continuous basis on a 47 mm diameter membrane filter of 0.8 micron porosity at a volumetric rate of approximately one cubic foot per minute (CFM). The filters are changed weekly, placed in glassine protective envelopes, and dispatched by U.S. Mail to the CV for Gamma Isotopic Analysis.

Filter samples are analyzed weekly for gross beta activity after sufficient time (usually 3 to 5 days) has elapsed to allow decay of Radon and Thoron daughters. If gross beta concentration in air particulate samples are greater than ten (10) times the yearly mean of the control samples, gamma isotopic analysis shall be performed on the individual samples. Quarterly composites from each location receive Gamma Isotopic Analysis using a Germanium detector. All identifiable gamma-emitters are quantified. Reporting units are pCi/m 3.

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

Periphyton(Slime) or Aquatic Vegetation Periphyton (slime) or aquatic plant samples are collected at or near locations used for surface water sampling. They are collected twice during the year (2nd and 3rd quarter), if available. The samples are analyzed for gross beta activity and, if available in sufficient quantity, for Sr-89, Sr-90, and by Gamma Isotopic Analysis. Reporting units are pCi/g wet weight.

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

Domestic Meat Domestic meat (chickens) may be collected once a year during the 3rd quarter, from six locations in the vicinity of the plant (K-20, K-24, K-27, K-29, K-34, and 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 collected. The fleshi is analyzed for gross alpha, gross beta, and by Gamma Isotopic Analysis to identify and quantify gamuna-emitting radionuclides. Reporting units are pCi/g wet weight.

Rev. II 3-3 12/14/2006

Ambient Radiation Two packets of thermoluminescent dosimeters (CaSO 4 : Dy cards) are placed at forteen locations, six of which are air sampling locations (K-If, K-2, K-7, K-8, K-16, and K-31) and four of which are milk sampling locations (K-3, K-5, K-25, and K-39); the remaining four locations are K -15, K-17, K-27, and 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 moisture each set of cards is sealed in a plastic bag and placed in a plastic container.

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) - 6 0Co Gamma +/-0.2 mR or +/-3%, whichever is greater. The maximum spread between areas on the same dosimeter is 3.5% at 1 standard deviation.

Reporting units for TLDs are mR/91 days for quarterly TLDs and mR/exposure period for annual TLDs.

Tests for uniformity and reproducibility of TLDs as specified in ANSI N545-1981 and NRC Regulatory Guide 4.13, are performed annually.

Well Water One gallon water samples are taken once every three months from four off-site wells, (K-10, K-11, K-13, and K-25) and two on-site wells (K-lh and K-ig). All samples are analyzed for gross beta in the total residue, K-40, tritium, and by Gamma Isotopic Analysis. Samples from one on-site well are analyzed for Sr-89, and Sr-90. Samples from K-lh and K-lg are also analyzed for gross alpha.

Reporting units are pCi/1.

Precipitation A monthly cumulative sample of precipitation is taken at Location K-11. This sample is analyzed for tritium. Reporting units are pCi/l.

Milk Milk samples are collected from two herds that graze within three miles of the reactor site (K-25 and K-34); from four herds that graze between 3-7 miles of the reactor site (K-3, K-5, K-38, and K-39);

and 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/i, iodine is separated Rev. I1 3-4 12/14/2006

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 137Cs/gK and 90Sr/gCa ratios are calculated. Reporting units are pCi/I 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 six dairy farms (K-3, K-5, K-25, K-34, K-38, and K-39) and from two on-site 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 six 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. If samples are not available from these locations, samples may be obtained from any local source so there is some sample of record. The location will be documented. In addition, two varieties of grain, if available, are collected annually from the farmland owned by Dominion Energy Kewaunee (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.

Egsz Quarterly samples of eggs can be taken from K-24, K-27, and 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, 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 six dairy farms and from an on-site 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.

Rev. II 3-5 12/14/2006

Surface Water Surface water is sampled monthly from Lake Michigan at the KPS discharge-(K-Id), 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 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-lk) 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, 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-l j), and one at the Two Creeks Park (K-I4), one at the Green Bay Municipal Pumping Station (K-9) are collected semi-annually (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.

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 2.2.1-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 if 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 that, 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 Report.

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.

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

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

g. The "upstream sample" shall be taken at a distance beyond significant influence of the discharge. The "downstream" sample shall 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.

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.

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

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 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:

LLD = 4.66sb E x V x 2.22 x Y x exp(--yAt)

Where:

LLD is the a priori lower limit of detection as defined above, as picocuries per unit mass or volume, Sb is the standard deviation of the background counting rate or of the counting rate of blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, 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, Typical values of E, V, Y, and At should be used in calculation.

Rev. 11 Page 2 of 3 12/14/2006

6 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.

f. This is NOT a NUREG-0472 required value. It is based on EPA drinking water standards, which tie into the NEI Groundwater Protection Initiative that was implemented at KPS on August 4, 2006.
