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.

On February 25, 2013, Dominion Energy Kewaunee submitted a certification of intent to cease power operations to the Nuclear Regulatory Committee. Power Operation of the Kewaunee Power Station ceased on May 7, 2013. The fuel was permanently removed from the reactor and placed in the spent fuel pool for storage on May 14, 2013.

This report summarizes the environmental operation data collected during the period January -

December 2016.

Dominion Energy Kewaunee, operator and owner of the Kewaunee Power Station, assumes responsibility for the environmental program at the Plant. Any questions should be directed to Mr. J.

Michael Hale, Radiation Protection I Chemistry Manager, at (920) 388-8103.

SUMMARY

Results of sample analyses during the period January - December 2016 are summarized in Table 4.5. Radionuclide concentrations measured at indicator locations are compared with levels measured at control locations and in preoperational studies. In no instance were REMP threshold reporting levels exceeded.

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

3.1 METHODOLOGY The sampling locations are shown in Figure 4-1. Table 4.1 describes the locations, lists for each direction and distance from the reactor, and defines which are indicators and 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 Ambient Gamma Radiation - TLDs Ambient gamma radiation is monitored at the six air sampling locations (K-1f, K-2, K-8, K-31, K-41 and K-43), at three milk sampling locations (K-3, K-5, and K-39), and from five additional sites (K-15, located 9.25 miles northwest of the plant; K-17, located 4.0 miles west of the plant; K-25, located 1.9 miles southwest of the plant; K-27, located 1.53 miles northwest of the plant and K-30, located 0.8 miles north of the plant ) by thermoluminescent dosimetry (TLD). Two TLD cards, each having four main readout areas containing CaS0 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.

Dosimeters have also been placed at eight additional locations (K-1 L through K-1 S), to monitor an Independent Spent Fuel Storage Installation (ISFSI). They are replaced and measured quarterly.

Airborne Particulates Airborne particulates are collected on 47 mm diameter, 1µm porosity glass fiber filters, at a volumetric rate of approx. one cubic foot per minute. The filters are collected weekly from six locations (K-1f, K-2, K-8, K-31, K-41 and K-43), and dispatched by mail to ATI Environmental, Inc..

for radiometric analysis. The particulate filters are counted for gross beta activity, a minimum of three days after the date of collection, to allow for the 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 traps are located at locations K-1f, K-2, K-8, K-31, K-41 and K-43. The traps are changed weekly and analyzed for iodine-131 immediately after arrival at the laboratory.

Precipitation Monthly composites of precipitation samples are collected at K-11 and analyzed for tritium.

3

3.1.2 The Terrestrial Program Milk samples are collected from two herds grazing within three miles of the reactor site (K-34 and K-38 ); from four herds that graze between 3-7 miles of the reactor site (K-3, K-5, K-35, and K-39);

and one from a dairy in Green Bay (K-42), 28.1 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. The samples are analyzed for iodine-131, strontium-89 and strontium-90, calcium, stable potassium and gamma-emitting isotopes.

Well Water Groundwater is collected quarterly from the four off-site well locations K-10, K-11, K-13 and K-38 and from two on-site wells located at K-1g and K-1h.

Gamma spectroscopic analysis, tritium and gross beta on the total residue are performed for each water sample. The concentration of potassium-40 is calculated from total potassium. Samples of water from the two on-site wells (K-1 g and K-1 h) are analyzed for gross alpha. Water samples from K-1g are also tested for strontium-89 and strontium-90.

• Domestic Meat Domestic meat is collected annually (if available) during the third quarter, from three locations in the vicinity of the plant (K-24, K-29, and K-32). The flesh is separated from the bone and analyzed for gross alpha, gross beta and gamma emitting isotopes.

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

Vegetables and Grain Annually, during the third quarter, five varieties of vegetables and samples of grain are collected from location K-26. Samples may also be obtained from other local sources to supplement the program (eg., K-3, and K-24). In addition, two varieties of grain or leafy vegetables are collected annually from farmland owned by Dominion Energy Kewaunee (K-23a and K-23b) and rented to a private individual for growing crops. The samples are analyzed for gross beta, strontium-89, strontium-90 and gainma emitting isotopes.

Cattle Feed Cattle feed (e.g., hay and silage) is collected during the first quarter from dairy farm locations (K-3, K-5, K-34, K-35, K-38 and K-39). The samples are analyzed for gross beta, strontium-89, strontium-90 and gamma emitting isotopes.

Grass Grass is collected during the second, third and fourth quarters from twq on-site locations (K-1 band K-1f) and from the dairy farm locations (K-3, K-5, K-34, K-35, K-38 and K-39). The samples are analyzed for gross beta, strontium-89, strontium-90 and gamma emitting isotopes.

Soil Soil samples are collected twice a year on-site at K-1f and from the dairy farm locations (K-3, K-5, K-34, K-35, 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 Program Surface Water Surface water samples are taken monthly from three locations on Lake Michigan: 1) at the point where the service water is discharged into Lake Michigan (K-1 d); 2) Two Creeks Park (K-14) located 2.6 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 NNE 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-1 a, K-1 b, and K-1e). Samples from North and Middle Creeks (K-1a, K-1b) are collected near the mouth of each creek. Samples from the South Creek (K-1e) are collected about ten feet downstream from the point where the outflow from the two drain pipes meets. Additionally, the drainage pond (K-1k),

located approximately 0.6 miles southwest of the plant, is included in the sampling program. Water samples at K-14 are collected and analyzed in duplicate.

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

Fish samples are collected during the second, third and fourth quarters near location K-1 d. The flesh is separated from the bones, gamma scanned and analyzed for gross beta activity. Bone samples are analyzed for gross beta, strontium-89 and strontium-90. Lafond's Fish Market (K-36) may be used for backup fish samples, if needed.

Aquatic Slime Periphyton algae (slime) or aquatic vegetation is collected during the second and third quarters from three Lake Michigan locations (K-1d, K-9 and K-14), from three creek locations (K-1a, K-1b and K-1e) and from the drainage pond (K-1k), if available. The samples 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-1 c, K-1d, K-1j, K-9 and K-14). The samples are analyzed for gross beta, strontium-89, strontium-90 and gamma emitting isotopes.

The mechanical failures on the air sample pumps were determined to be caused by failure of the carbon blades. (CR746, CR 756 and CR784). When discovered, the sample pumps were replaced with rebuilt pumps and a midweek check for proper operation was completed as a follow up action. Recurring failures happened after this midweek check. When the cause was determined to be a faulty batch of carbon blades, the sample pumps were rebuilt with a carbon blades from a different batch/lot.

3.1.5 Program Modifications None.

3.2 RESULTS AND DISCUSSION Results for the reporting period January to December, 2016 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.

Results of all measurements made in 2016 are not included in this section, although references to these results will be made in the discussion. A complete tabulation of results is provided in Part II of the 2016 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 2016. The Chernobyl and Fukushima Daiichi nuclear accidents occurred on April 26, 1986 and March 11, 2011, respectively.

The last reported atmospheric nuclear test was conducted by the People's Republic of China on October 16, 1980. Contributions from these events have resulted in the presence of long-lived radioisotopes of cesium and strontium still detectable in the environment.

3.2.2 The Air Environment Ambient Gamma Radiation -TLDs Ambient gamma radiation was monitored by TLDs at fourteen locations, eight indicators and six controls. TLDs at the indicator locations measured a mean dose equivalent of 16.5 mR/91 days, in close agreement with the control locations 15.9 mR/91 days. The readings are similar to the averages obtained from 2002 (and prior to) through 2015.

For eight TLDs monitoring the Independent Spent Fuel Storage Installation (Protected Area), (K-1 L through K-1S), measurements averaged 14.5 mR/91 days.

No plant effect on ambient gamma radiation was indicated. These values are 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 18.0 mR/91 days, measured at indicator location K-27.

Average quarterly dose rates.

Using ANSl/HPS N13.37-2014 as guidance, a determination of facility related dose was performed using quarterly TLD data from control and indicator locations from 2005 through 2015. A baseline background dose (B 0 ) was computed for each TLD location. Then a Quarterly Minimum Differential Dose (MDD 0 )

1 was calculated as 3 times the 90 h percentile of the standard deviations of the historical quarterly results.

The result of this calculation was 6.9 mrem. Transit and storage doses weren't considered since the TLD's currently are, and have historically been, collected in the field and delivered to the laboratory for immediate processing.

2016 results at all locations both indicator and control were lower than the sum of the Baseline Background Dose(B 0 ) and the Quarterly Minimum Differential Dose(MDD 0 ), which according to ANSl/HPS-N13.37-2014 indicates no detection(ND) which supports the conclusion that there is no plant effect Normalized Quarterly Monitoring Data Quarterly Facility Dose Quarterly Mo (mrem per standard quarter) Fa = Mo - [Bo+MDDo](mrem)

Airborne Particulates The annual gross beta concentration in air particulates averaged 0.021 pCi/m 3 at the indicator location and 0.020 pCi/m 3 at the control locations, similar to the means observed from 2002 (and prior to) through 2015. There is no indication of a plant effect, the average readings were evenly distributed between indicator and control locations. New sampler pumps were installed in the third quarter of 2010. The slight increases in beta activity may be due to a change in the calculated volume. Results are tabulated below.

Variation in the gross beta activity throughout the year is not unusual. Typically, higher beta averages occur during the months of January and December, and the first and fourth quarters, as noted in data from 2002 through 2016.

Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, produced continuously in the upper atmos:rhere by cosmic radiation, was detected in all samples, with an average activity of 0.070 3

pCi/m at the indicator locations and an average of 0.069 pCi/m at the control locations. All other gamma-emitting isotopes were below their respective LLD limits.

Airborne Iodine Levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.030 pCi/m 3 at all locations. There was no indication of a plant effect on the local air environment.

Precipitation Precipitation was monitored for tritium at indicator location, K-11. The concentration was below the LLD level of 180 pCi/L in all samples.

9

3.2.3 The Terrestrial Environment 126 milk samples were tested for the presence of iodine-131, all measured below an LLD level of 0.5 pCi/L.

Strontium-89 concentrations measured below an LLD level of 1.5 pCi/L in all samples. Measurable levels of strontium-90 above an LLD level of 0.9 pCi/L were detected in six of eighty-four samples tested. Mean values were 0.9 pCi/L for indicator locations and 1.0 pCi/L for control locations and are similar to averages seen from 1990 through 2015.

For gamma emitting isotopes, concentrations measured below the required limits of 15 pCi/L for barium-lanthanum-140 and 10 pCi/L for cesium-134 and cesium-137. Potassium-40 results were comparable at the indicator and control locations (1376 and 1371 pCi/L, respectively), and are consistent with levels observed from 1990 through 2015.

Detection of strontium, iodine and potassium activity is consistent. with findings of the National Center for Radiological Health (1968). Most radiocontaminants in cattlefeed do not find their way into milk, exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine. Due to chemical* similarities between strontium and calcium, and cesium and potassium, organisms tend to deposit strontium-89 and strontium-90 in bone and cesium-137 in the soft tissue and muscle Consequently, ratios of strontium-90 activity to the weight of calcium in milk and cesium-137 activity to the weight of potassium in milk were monitored in order to detect potential environmental accumulation of these radionuclides. Measured concentrations of calcium are in agreement with previously determined values and averaged 0.99 g/L at the indicator location and 0.96 at the control locations . Measured concentrations of stable Potassium were averaged 1.69 g/L at the indicator locations and 1.67 g/L at the control locations.

There was no indication of any effect due to the operation of the Kewaunee Power Station.

Well Water One of eight samples tested for gross alpha from on-site well K-1 h was slightly above the LLD of 4.8 pCi/L with an activity of 5.0 pCi/L. Gross beta activity above a detection limit of 3.7 pCi/L, was measured in three of the twenty-four indicator samples tested at an average of 12.9 pCi/L. The largest contribution to this average was the sample collected April 41h from location K-38 with a gross beta activity of 29.9 pCi/L. The primary contribution to this high gross beta result was due to naturally-occurring potassium-40 which was detected at an activity of 31.3 pCi/L. It is not unusual to see high potassium-40 levels in an agricultural setting. Potassium-40 is present wherever stable potassium is found. Therefore this result can be attributed to agricultural runoff. The gross alpha activities are most likely contributions from naturally-occurring daughters of radium and thorium when detected in the ground water.

Levels of strontium-89 and strontium-90 were measured for the on-site well (K-1g). The concentrations measured below LLD values of 0.7 and 0.5 pCi/L, respectively.

Samples were tested for tritium and gamma emitting isotopes. All tritium concentrations measured below a detection level of 149 pCi/L. Gamma-emitting isotopes measured below respective LLDs.

Domestic Meat In domestic meat samples, gross alpha measured below the LLD of 0.036 pCi/g wet for both samples tested, while the gross beta concentrations measured 2.79 pCi/g wet and 2.54 pCi/g wet for indicator and control samples respectively. Gamma-spectroscopic analyses showed that most beta activity was due to naturally occurring potassium-40 (2.53 pCi/g wet for the indicator and 2.29 pCi/g wet for the control). AIL other gamma-emitting isotopes measured below detection limits.

10

In samples of eggs tested, the gross beta concentrations averaged 1.58 pCi/g wet at the indicator location and 1.38 pCi/g wet for the control location, similar to observed concentrations of naturally-occurring potassium-40 (1.36 and 1.35 pCi/g wet respectively). Other gamma-emitting isotopes were below their respective LLDs.

Levels of strontium-89 measured less than 0.008 pCi/g wet in all samples. Strontium-90 measured less than 0.003 pCi/g wet in all samples tested.

Vegetables and Grain In vegetables an average gross beta concentration of 2.97 pCi/g wet was measured at the two indicator samples and an average of 2.70 pCi/g wet was measured for the six control samples from location K-26, due primarily to potassium-40 activity. All other gamma emitting isotopes measured below detection levels. No strontium-89 was detected above an LLD of 0.009 pCi/g wet. No strontium-90 was detected above an LLD of 0.005 pCi /g wet.

In two samples of grain consisting of clover and wheat collected from indicator location K-23, the gross beta concentrations averaged 7.31 pCi/g wet, due primarily to activity from potassium-40 and beryllium-?. Strontium-89 measured below an LLD of 0.031 pCi/g wet. Strontium-90 was measured at one of the two grain samples from indicator location K-23 at level of 0.031 pCi/g wet. The other sample measured below an LLD of 0.004 pCi/g wet.

These results compare with results from past years and do not indicate a plant effect.

Cattle Feed For cattlefeed, average gross beta concentrations were 12.26 and 12.73 pCi/g wet at the indicator and control locations respectively, and reflected average potassium-40 levels observed of 9.98 and 10.54 pCi/g wet, at the indicator and control locations respectively. No strontium-89 activity was detected above an LLD of 0.044 pCi/g wet. Strontium-90 was measured in five of the eight indicator samples tested at an average activity of 0.018 pCi/g wet. Strontium-90 was also found in three of the four control location samples and averaged 0.017 pCi/g wet.

No plant effect is indicated.

In grass, mean gross beta measured 7.83 and 8.78 pCi/g wet at indicator and control locations, respectively, In all cases the activity was predominantly due to naturally occurring potassium-40 and beryllium-?. Other gamma-emitting isotopes were below respective LLDs. Strontium-89 tested below detection limits of 0.066 pCi/g wet for all samples and Strontium-90 was measured below the detection limit of 0.026 pCi/g in all samples.

With the exception of the naturally-occurring beryllium and potassium, gamma-emitting isotopes were below detection levels.

Gross alpha concentrations in soil averaged 8.45 pCi/g dry in all ten indicator location samples and 6.96 pCi/g dry at the two control locations. Mean gross beta levels measured at indicator and control locations averaged 28.10 and 24.66 pCi/g dry, respectively, primarily due to potassium-40 activity. Strontium-89 was below an LLD level of 0.11 pCi/g dry in all samples. Strontium-90 was below an LLD of 0.039 pCi/g for all fourteen samples analyzed.

Cesium-137 was detected in all fourteen soil samples at an average of 0.10 pCi/g dry at both the indicator and control locations. Trace levels of Cs-137 in the environment can be attributed to 11

nuclear testing and accidents. Potassium-40 was detected in all samples and averaged 19.98 and 18.08 pCi/g dry for indicator and control locations, respectively. All other gamma-emitting isotopes were below respective LLD's. The levels of detected activities are similar to those observed from 1990 through 2015. The data suggests no evidence of a plant effect.

3.2.4 The Aquatic Environment Surface Water Gross beta activity in surface water measured higher at the indicator locations (5.2 pCi/L) than at the control locations (1.6 pCi/L). A similar pattern of activity has been observed since 1978. In 2016, the highest activities measured were sampled from the K-1a. The average activity was 13.4 pCi/L, with a range of 3.9 to 62.6 pCi/L, due primarily to potassium-40 activity. The potassium-40 concentrations averaged 12.1 pCi/L and ranged from 3. 7 to 64.1 pCi/L.

4 These differences in activity are due in part to the indicator location (K-1 k), a pond formed by 4 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-1a and K-1e) which are much higher in gross beta concentration and exhibit large month-to-month variations. The K-1a creek draws its water from the surrounding fields which are heavily fertilized; and the K-1e 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 fluctuations in beta concentration were due to variations in potassium-40 concentrations and were not due to plant operations. The fact that similar fluctuations at these locations were observed in pre-operational studies conducted prior to 1974 supports this assessment.

No tritium was detected above an LLD of 173 pCi/L in the thirty-six samples tested, (quarterly composites of monthly samples).

All analyses for strontium-89 measured below an LLD of 2.0 pCi/L. All analyses for Strontium-90 measured below an LLD of 0. 7 pCi/L.

With the exception of naturally occurring potassium-40, gamma-emitting isotopes measured below their respective LLDs in all samples.

12

In fish, gross beta concentrations averaged 4.00 pCi/g wet in flesh and 3.19 pCi/g wet in bone fractions. In flesh, the gross beta concentration was primarily due to potassium-40 activity.

Excluding potassium-40, gamma-emitting isotopes measured below their respective LLDs in all samples.

Strontium-89 concentrations in the bone were below an LLD of 0.33 pCi/g wet. Strontium-90 was detected in two of the three samples at an average of 0.18 pCi/g wet.

Aquatic Slime In periphyton algae(slime) and aquatic vegetation samples, mean gross beta concentrations for indicator and control locations measured 3.01 and 6.15 pCi/g wet, respectively, due primarily to combined potassium-40 and beryllium-7 activity of 3.72 and 5.09 pCi/g wet, respectively.

Trace Antimony-125 activity was detected in one of fifteen indicator samples at 0.054 pCi/g wet compared to a detection level of 0.032 pCi/g wet. Cesium-137 was measured in eight of fifteen indicator samples, at a level of 0.012 pCi/g wet. Other gamma-emitting isotopes, with the exception of naturally-occurring beryllium-7 and potassium-40, were below their respective LLDs.

No strontium-89 was measured above the detection level of 0.056 pCi/g wet. Strontium-90 activity was measured at an average of 0.018 pCi/gwet at six of fifteen samples from the indicator locations.

Strontium-90 was also measured at 0.018 pCi/g wet at one of the two control samples tested.

These measurements are consistent with measurements obtained in past years and do not indicate a plant effect.

Bottom Sediments In bottom sediment samples, the mean gross beta concentrations measured an average 8.91 pCi/g dry at the indicator locations versus an average of 18.92 pCi/g dry at the control location.

Cesium-134 measured below the LLD level of 0.020 pCi/g dry for all samples tested. Cesium-137 measured below an LLD of 0.027 pCi/g dry for all locations. Other gamma-emitting isotopes, with the exception of naturally-occurring potassium-40, were below their respective LLDs.

Strontium-89 was measured below an LLD of 0.086 pCi/g dry for all samples. Strontium-90 was measured below an LLD of 0.037 pCi/g dry for all locations.

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 2

garden of greater than 50m (500 ft2) producing broad leaf vegetation." (Figure 4-1)

The 2016 Land Use Census was completed to identify the presence of the nearest milk animals, gardens and farm crops surrounding the Kewaunee Power Station. The Land Use Census was completed on September 6, 2016. The census is conducted annually during the growing season per Health Physics Procedure RP-KW-001-014.

In summary, the highest D/Q locations for nearest garden, nearest residence and nearest milk animal did not change from the 2015 census.

Results are reported in Appendix A. TLD lntercomparison 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, 2016 through December, 2016

Appendix A lnterlaboratorv Comparison Program 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 RAD PT Study Proficiency Testing 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.

Table A-2 lists results for thermoluminescent dosimeters (TLDs), via irradiation and evaluation by the University of Wisconsin-Madison Radiation Calibration Laboratory at the University of Wisconsin Medical Radiation Research Center.

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 lists REMP specific analytical results from the in-house "duplicate" program for the past twelve months. Acceptance is based on the differe11ce of the results being less than the sum of the errors.

Complete analytical data for duplicate analyses is available upon request.

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

Results in Table A-7 were obtained through participation in the MRAD PT Study Proficiency Testing Program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).

Attachment A lists the laboratory precision at the 1 sigma level for various analyses. The acceptance criteria in Table A-3 is set at +/- 2 sigma.

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

• Results are reported in units of Bq/kg (soil), Bq/L (water) or Sq/total sample (filters, vegetation).

b Laboratory codes as follows: MAW (water), MAAP (air filter), MASO (soil), MAVE (vegetation).

0 MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP. A known value of "zero" indicates an analysis was included in the testing series as a "false positive". MAPEP does not provide control limits.

d Provided in the series for "sensitivity evaluation". MAPEP does not provide control limits.

• The laboratory properly identified the Sn-75 interfering peak in the vicinity of Co-57 and stated so in the comment field. MAPEP requires results to be reported as an activity with an uncertainty. Since the calculated uncertainty was less than the activity MAPEP interpreted the submitted result as a "false positive" resulting in a failure.

1 Original analysis for Ni-63 failed.

9 Reanalysis with a smaller aliquot resulted in acceptable results. An investigation is in process to identify better techniques for analyzing samples with complex matrices.

h MAPEP states that samples contain two fractions of Uranium; one that is soluble in concentrated HN0 3 and HCl acid and one that is "fundamentally insoluble in these acids". They also state that HF treatment can not assure complete dissolution.

Results are consistent with measuring the soluble form.

APPENDIX 8. DATA REPORTING CONVENTIONS 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 = 2cr 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 4.66cr uncertainty for a background sample.

3.0. Duplicate analyses If duplicate analyses are reported, the convention is as follows. :

3.1 Individual results: For two analysis results; x1 +/- s 1 and x2 +/- s2 Reported result: x +/- s; where x = (1/2) (x1 +~)ands= (1/2) ~ s; + s~

3.2. Individual results: < L1 , < 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 ~nnual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation "s" of a set of n numbers x1 , x2 . . . xn are defined as follows:

s---~ -\J~

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 numbers 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 B-1

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.

Long Description Three of the six Radiological Environmental Monitoring Program (REMP) air samplers were found not running on 8/22/16. The environmental air samplers are required by the REMP. Sample collection is performed in accordance with procedure SP-63-164, Environmental Sample Collection.

Air sample pumps at the (allowing locations were found not running prior to a normal weekly run time of 168 hour0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br />s:

-Klf at Kewaunee Power Station Meteorological Tower failed after 124 hours0.00144 days <br />0.0344 hours <br />2.050265e-4 weeks <br />4.7182e-5 months <br />.

-K-31 at East Krok Electric Substation failed after lOS Hours

-K41 at Point Beach Emergency off-site Facility (EOF) In Green Bay failed after 86 Hours.

This Is a repeat occurrence (see CR 746). A faulty batch/lot of carbon blades used for air sample pump annual maintenance is suspected to be the cause. As a follow on action to this previous issue, the sample pumps at all six locations were checked and verified to be running properly on 8/19/16. All three failures occurred after this check was completed.

The failed sample pumps have been replaced with rebuilt sample pumps. The sample pumps are being rebuilt with a different batch/lot of carbon vanes.

Initial Actions Contacted SME and RP supervision. RP Instrument Technician replaced all three air sample pumps. More frequent monitoring of air sampler performance In the field is In progress. There Is also telemetric monitoring on the pumps which notifies RP/CY Personel if pump failure occurs.
