Appendix A lnterlaboratory/ lntralaboratory 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.
Appendix A lnterlaboratory/ lntralaboratory 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.

The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed in 2018 in accordance with AP 078-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)].
The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed in 2018 in accordance with AP 078-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)].
No program changes are necessary regarding milk locations. Again, no milk sampling locations were identified.
No program changes are necessary regarding milk locations. Again, no milk sampling locations were identified.
Line 1,117: Line 2,582:
Table 5-1, Attachment A, of procedure AP 078-004, also requires that milk samples be collected from "three indicator locations within 5 miles of the site having the highest dose potential."
Table 5-1, Attachment A, of procedure AP 078-004, also requires that milk samples be collected from "three indicator locations within 5 miles of the site having the highest dose potential."
METHODOLOGY Over two hundred surveys were mailed to the rural residents living within five miles of WCGS.
METHODOLOGY Over two hundred surveys were mailed to the rural residents living within five miles of WCGS.
The survey excluded the residents of New Strawn and Burlington. These locations were excluded due to the large number of households and the low likelihood that information gained from these residences would affect the locations chosen for REMP sampling. Drive-by information was collected for the nearest residences in each sector that did not return surveys.
The survey excluded the residents of New Strawn and Burlington.
These locations were excluded due to the large number of households and the low likelihood that information gained from these residences would affect the locations chosen for REMP sampling.
Drive-by information was collected for the nearest residences in each sector that did not return surveys.
The information collected was compiled and the results are identified in Tables 1-3.

SUMMARY

Plant-related activation, corrosion, or fission products were not detected during 2018 in air particulate filters, radioiodine canisters, ground water, drinking water, broadleaf vegetation, shoreline sediment, crops, bottom sediment, aquatic vegetation, terrestrial vegetation or soil samples. Activation, corrosion or fission products attributable to plant operation were detected during 2018 in surface water, fish, and deer samples.

Nuclides detected in Radiological Environmental Monitoring Program (REMP) samples were below applicable Nuclear Regulato'ry Commission (NRC) reporting levels.

Based upon the REMP results, it was concluded station operations had no significant radiological impact on the health and safety of the public or the environment.

INTRODUCTION The 2018 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2018. WCGS is located in Coffey County, Kansas, approximately five miles northeast of Burlington, Kansas.

Fuel loading commenced at WCGS on March 12, 1985. The operational phase of the REMP began with initial criticality on May 22, 1985, and the first detectable quantities of radioactivity were reported in plant effluents in June 1985.

This report contains a* description of the REMP conducted by Wolf Creek Nuclear Operating Corporation (WCNOC), a discussion of monitoring program results, the revisions or changes to the program, program deviations, the lnterlaboratory Comparison Program and a comparison to

  • the Radioactive Effluent Release Program. The. lnterlaboratory Comparison Program results, a summary of results in the NRC Branch Technical Position specified format,* the individual sample results, and the Land Use Census Report are included as appendices.

I. PROGRAM DESCRIPTION Radiological environmental monitoring samples were collected according to the schedule in WCGS procedure AP 078-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program). Radiological environmental monitoring program samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc.

Landauer, Inc. processed the environmental optically stimulated luminescence (OSL) dosimeters. Table 1 identifies the exposure pathway/sample type, number of samples and sample locations, sample collection frequency, and the type and frequency of analysis. Table 2 lists the sample location identifiers, distances and directions from the plant. Samples in addition to those required by AP 078-004 were also obtained and analyzed.

The following is a description of the sampling and analysis program by individual pathways.

A. Airborne Pathway Low volume air sampling pumps with digital flow meters continuously sampled air through 47 mm glass fiber particulate filters and radioiodine canisters, respectively. The air particulate filters and radioiodine canisters were collected weekly.

Gross beta analysis was performed weekly on the air particulate filters. Gamma isotopic analysis was also performed quarterly on 2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 1 of 31

the air particulate filters. Radioiodine canisters were analyzed weekly for 1-131.

Air samples were collected from six locations. The indicator locations sampled included 2, 18, 32, 37 and 49. A control location near the intersection of 20th Road and Yearling Road (location

53) was also sampled. Indicator sample locations are shown in Figure 1 and the control sample location is shown in Figure 5.
8. Direct Radiation Pathway Optically stimulated luminescence (OSL) dosimeters were used continuously at 42
  • locations during the sample year to measure direct radiation. The OSLs were typically positioned roughly 3 to 4 feet above the ground in plastic thermostat boxes. Three OSLs were placed at each designated location. The OSLs were changed out quarterly and analyzed quarterly for gamma dose. Transit dose was measured and subtracted from the ambient dose.

Indicator OSL sample locations are illustrated in Figure 2 and control sample locations are shown in Figure 5.

Control sample locations were 39 (Beto Junction) and 53 (near the intersection of 201h Road and Yearling Road).

. C. Waterborne Pathway Gamma isotopic analysis was performed on the water samples. In addition to gamma isotopic analysis, analysis for 1-131 was performed monthly on -drinking water and quarterly on ground water samples. Gross beta analysis was performed monthly on drinking water samples. Tritium analysis was performed monthly for surface water and quarterly for drinking water. Tritium analysis was also performed quarterly on ground water samples. Four surface water samples from the Coffey County Lake Spillway (SP) location and four surface water samples from the John Redmond Reservoir (JRR) location were also analyzed for Fe-55.

The waterborne pathway sample locations are shown in Figures 3 and 5.

Monthly grab samples of surface water were collected from the John Redmond ReseNoir (JRR) control location and from the Coffey County Lake Spillway (SP) indicator location.

Quarterly grab samples of ground water were collected from seven wells. Six locations (C-10, C-49, F-1, G-2, J-1 and J-2) located hydrologically down gradient from the site.were used as indicator sample locations. Location 8-12 located hydrologically up gradient from the site was used as*a control location.

Drinking water was sampled at the water treatment facilities in the towns of Iola (indicator sample location 10-DW) and Burlington (control sample location BW-15). The Iola facility is located downstre~m of the Neosho River-Wolf Creek confluence and the Burlington facility is located upstream* of the Neosho River-Wolf Creek confluence.

II. DISCUSSION OF RESULTS Analysis results for pathways are summarized in Appendix B using the format described in Radiological Assessment Branch Technical Position, Revision 1, November 1979 (NRC Generic Letter 79-065). Results for individual samples are listed in Appendix C.

A. Airborne Pathway.

Chart 1 graphically illustrates weekly gross beta results for the sample year. Chart 2 represents the gross beta historical airborne smoothed averages of indicator sample locations and control sample locations. Charts 1 and 2 demonstrate how closely the indicator and control sample locations tracked together. Chart 2 reveals a seasonal cyclic trend; the gross beta values peak in the winter months (December or January) and decrease to a low point in the spring months (May or June). This trend is* expected and is attributed to seasonal meteorological changes, i.e., changes in prevailing winds and precipitation.

The gross beta results of 2018 were compared to pre-operational monitoring results of 1983 and

  • 1984. The weekly gross beta analyses range for 1983 and 1984 was 0.0064 to 0.084 pCi/m3.

The 2018 weekly gross beta analyses range for indicator locations was 0.006 to 0.059 pCi/m3*

The 2018 weekly gross beta analyses range was within the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2018 (0.026 pCi/m3) was lower than the annual mean for 1983 (0.032 pCi/m3).

The gross beta results for the indicator locations were also compared to the control location.

The annual mean for indicator locations for 2018 (0.026 pCi/m3) was slightly higher than the annual mean of the control location (0.025 pCi/m3). The indicator location with the highest gross beta annual mean was location 37 (0.026 pCi/m3) and was slightly higher than the annual mean of the control location (0.025 pCi/m3).

Naturally occurring Be-7 activity was detected, as was the case during. pre-operational monitoring. In 1984, the range for Be-7 detected activity was 0.024 to 0.211 pCi/m3 for indicator locations and the annual mean for indicator locations was 0.069 pCi/m3. In 2018, the range for Be-7 detected activity was 0.060 to 0.117 pCi/m3 for indicator locations and the annual mean for indicator locations was 0.082 pCi/m3*

The control location annual mean for Be-7 detected activity (0.077 pCi/m3) was slightly lower than the annual mean of the indicator locations (0.082 pCilm} The indicator location with the highest annual mean of detected Be-7 activity (0.087 pCi/ m ) was location 37.

1-131 activity was not detected in the weekly analysis of radioiodine canisters at any location.

The AP 078-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2018 in air particulate filters and radioiodine canisters. No unusual-trends were noted.

2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 31

B. Direct Radiation Pathway Quarterly 9sL dosimeter results for each location are shown in Table 3. Measured values have been converted to a standardized 90-day quarter.

The annual mean of indicator sample locations in 2018 was 18.3 mR per standardized 90-day quarter.

The annual mean of the control sample locations in 2018 was 18.5 mR per standardized 90-day quarter.

. For pre-operational comparison, in 1981, the annual mean of indicator sample locations was 18.9 mR per standardized 90-day quarter and the annual mean for the control sample locations was 17.1 mR per standardized 90-day quarter.

It should be noted WCGS changed from thermoluminescence dosimeters (TLD) to optically stimulated luminescence (OSL) dosimeters in 2008.

The indicator sample location with the highest annual mean was location 50 (21.2 mR per standardized 90-day quarter) which is slightly higher than the annual mean of the control sample locations (18.5 mR per standardized 90-day quarter).

Based upon Condition Report 00027489, improvements were made in measuring and subtracting transit dose in 2010. As expected, the OSL results have increased since 2010.

Chart 3 visibly displays the increase of the OSL results since 2010. Chart 3 also displays how closely the indicator and control location OSL dosimeter results are for 2018. Condition Report 00128355 was written to reduce data elimination based on standard deviation starting in Quarter 3 of 2018. No change in trend was noted.

Chart 4 displays the TLD nearsite sample locations (1, 2, 7-9, 11-14, 18, 26, 27, 29, 30, 37 and

38) and the control sample locations (locations 39 and 48) for the preoperational years through 2007.

C. Waterborne Pathway (1) Surface Water Tritium, attributable to WCGS operation, was detected in surface water samples collected from the Coffey County Lake spillway (SP) indicator sample location. The annual mean for detected tritium activity at the SP location was 11,941 pCi/L and the range was 9101 to 14,775 pCi/L.

The detected tritium activity was below the 30,000 pCi/L AP 078-004 reporting level. Chart 5 illustrates the yearly averages of surface water tritium data for* the SP location.

Chart 5 indicates the average tritium concentration of the SP location has declined the last three years.

Tritium activity was not detected in samples obtained from the John Redmond Reservoir (JRR) control sample location.

During pre-operational radiological environmental monitoring, measured radiological activity was not detected in surface water samples.

The AP 078-004 required lower limits of detection were met. Radionuclides were not detected by the gamma isotopic analyses or by Fe-55 analyses.

2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 31

Tritium was the only activity detected during 2018 in surface water samples and no unusual trends were noted.

(2) Ground Water The AP 078-004 required lower limits of detection were met for 1-131, tritium and gamma isotopic analyses. Radioactivity was not detected in any ground water samples. No unusual trends were noted. Plant-related activation, corrosion or fission products were not detected during 2018 in ground water samples.

(3) Drinking Water Gross beta activity was detected in drinking water samples collected from the indicator sample location and in samples collected from the control sample location. The annual mean of the indicator sample location gross beta activity (3.02 pCi/L) was slightly lower when compared to the annual mean of the control sample location gross beta activity (3.05 pCi/L).

The 2018 annual means of gross beta activity for both the indicator and control sample locations were lower than those of the pre-operational monitoring year of 1984. In 1984, the annual mean of the indicator sample location gross beta activity was 7.5 pCi/L and the annual mean of the control sample location gross beta activity was 6A pCi/L.

Chart 6 illustrates the drinking water gross beta results for the last five years and how closely the gross beta results compared for the indicator and control sample locations.

Tritium was detected in the indicator sample location during the third quarter 2018 (252 pCi/L),

which is attributable to plant operation. Heavy rainfall increased outfall from Wolf Creek Cooling Lake and was detected downstream. No release limits were exceeded and results were well below required detection limits. No other radionuclides were detected by the gamma isotopic,

analyses of the indicator or control location samples.

The AP 078-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2018 in drinking water samples and no unusual trends were noted.

(4) Shoreline Sediment Naturally occurring K-40 was detected in shoreline sediment samples collected from the DC (indicator sample location) and JRR (control sample location). K-40 was also detected during pre-'operational shoreline sediment monitoring.

No other radionuclides were detected in the DC or JRR shoreline sediment samples during 2018. The AP 078-004 required lower limits of detection were met. Plant-related activation,

  • corrosion, or fission products were not detected during 2018 in shoreline sediment samples and no unusual trends were noted.

D. Ingestion Pathway (1) Milk Milk was not collected during the sample year since no indicator locations within five miles of the*

plant were identified during the 2018 Land Use Census.

2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 31

(2) Fish Naturally occurring K-40 activity was detected in fish samples obtained frorn the Coffey County Lake (CCL) indicator sample location and in fish samples obtained from the JRR control sample location. K-40 activity was also detected during pre-operational fish monitoring.

Fish samples were also analyzed for tritium. Fish samples collected from Coffey County Lake had tritium activity detected (7,474 pCi/kg annual mean).

The detected tritium activity was attributable to plant operation.

An adult consuming 21 kilograms of fish, at the maximum measured tritium concentration (9,791 pCi/kg), would receive a committed ~ffective dose equivalent of 0.013 mRem.

Tritium activity was not detected in the control location samples collected from JRR.

No other radionuclides were detected in fish samples during 2018. The AP 078-004 required lower limits of detection were met and no unusual trends were noted.

(3) Broadleaf Vegetation Gamma analyses of broadleaf vegetation samples obtained from indicator and control sample locations detected naturally occurring 8e-7 and K-40. 8e-7 and K-40 activity were also detected pre-operationally.

No other radionuclides were detected in broadleaf vegetation samples collected during the year.

The AP 078-004 required lower iimits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2018 in broadleaf vegetation samples and no

  • unusual trends were noted.

(4) Crop Samples Gamma analysis detected naturally occurring K-40 activity to *be present in the samples collected from the indicator sample locations and in the samples collected from the control sample location. K-40 activity was also detected during pre-operational crop monitoring. K-40 was the only activity detected in the crop samples.

The AP 078-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2018 in crop samples and no unusual trends were noted.

E. Additional Samples Collected (not required by AP 07B-004)

(1) Bottom Sediment Gamma analysis detected naturally occurring K-40 activity to be present in the samples collected from the indicator sample locations and in the samples collected from the control sample location.

K-40 activity was also detected during pre-operational bottom sediment monitoring.

Cs-137 activity was detected in three samples obtained from indicator locations (range 46.8 to 89.7 pCi/kg). Cs-137 was detected in one sample obtained from control location (95.7 pCi/kg).

2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 31

Cs-137 activity was detected in pre-operational samples. The Cs-137 activity detected in 2018 indicator sample location bottom sediment samples was within the pre-operational range.

(Cs-137 activity detected in 1981 and 1982 was in the range of 79 to 953 pCi/kg. The decay corrected range of pre-operational Cs-137 activity detected is approximately 34 to 415 pCi/kg.)

The detected Cs..a137 activity in the samples collected from the indicator sample locations was likely due to fallout since the measured activity is within the decay corrected range of pre-operational Cs-137 detected activity.

Chart 7 plots the Cs-137 detected activity from the discharge cove indicator sample location and JRR control sample location bottom sediment samples. The detected Cs-137 activity measured from the discharge cove location reflects a decreasing trend. The Chart 7 trendline indicates Cs-137 activity detected at the JRR control location has also been decreasing. Chart 7 also displays that in recent years, the detected Cs-137 activity for the JRR and* DC sample locations overlap.

Fe-55 activity was not detected in the fourteen samples obtained from indicator sample locations.

Analysis for the Hard-to-Detect radionuclides was performed on two indicator location samples.

Sr-90 activity (range 32.4 to 32.6 pCi/kg) was detected in two bottom sediment sample collected from the Ultimate Heat Sink (UHS) area.

Sr-90 activity was detected in pre-operational soil samples. (Sr-90 activity detected in February 1985 soil samples was in the range of 85 to 380 pCi/kg. The decay corrected range of pre-operational Sr-90 activity detected is approximately 38 to 171 pCi/kg.) The detected Sr-90 activity in the bottom sediment collected from the UHS indicator sample location is likely due to fallout since the activity is below the decay corrected pre-operational range.

No other radionuclides were detected in bottom sediment samples. Plant-related activation, corrosion, or fission products were not detected during 2018 in b~ttom sediment samples and no unusual trends were noted.

(2) Aquatic Vegetation Gamma analyses of aquatic vegetation samples obtained from indicator sample locations detected naturally occurring Be-7 and K-40. Be-7 and K-40 activity were also detected during pre-operational monitoring.

No other radionuclides were detected in aquatic vegetation samples. Plant-:related activation, corrosion, or fission products were not detected during 2018 in aquatic vegetation samples and no unusual trends were noted.

2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 31

(3) Terrestrial Vegetation Naturally occurring Be-7 and K-40 activity were detected in the terrestrial vegetation indicator location samples. No other radionuclides were detected in terrestrial vegetation. Plant-related activation, corrosion or fission products were not detected during 2018 in terrestrial vegetation and no unusual trends were noted.

(4) Soil Naturally occurring K-40 activity was detected in the soil sample that was collected from the indicator location. K-40 activity was also detected during pre-operational soil monitoring.

Cs-137 activity was also detected in the soil sample (181.9 pCi/kg) obtained from the indicator location. Data was reviewed for soil samples collected pre"-operationally. The detected Cs-137 activity range from February of 1985 was 255 to 2,160 pCi/kg. The decay corrected range of pre-operational Cs-137 activity detected in soil is approximately 120 to 1,014 pCi/kg.

The detected Cs-137 activity in soil sampled in 2018 is below the decay corrected pre-operational.

range and is likely due to fallout.

Plant-related activation, corrosion, or fission products were not detected during 2018 in soil samples and no unusual trends were noted.

(5) Turkey Naturally occurring K-40 activity was detected in the turkey sample obtained from the indicator location.

Tritium activity (612 pCi/kg) was also detected in the turkey sample.

The detected tritium activity was attributable to plant operation.

An adult consuming 72.6 kilograms of turkey meat, at the measured tritium concentration (612 pCi/kg), would receive a committed effective dose equivalent of 0.003 mRem.

No other radionuclides were detected in the turkey sample. No unusual trends,were identified.

Ill. PROGRAM REVISIONS/CHANGES Procedure changes were made in AP 07B~004, Offsite Dose Calculation Manual (Radiological Environm~ntal Monitoring Program), in 2018.

Procedure was reformatted in VEPROMS for future revisions.

  • Unnecessary references and redundant notes were removed. 8hanges were made in Attachment B for steps involving handling of vendor records and vendor qualifications to clarify responsibilities.

I OSL Dosimeters data will no longer be excluded based on standard deviation. Data exclusion should be a rare exception. Due to the nature of OSLs and being in the environment, standard deviation is not a good indicator of data validity (Condition Report 00128355).

IV. PROGRAM DEVIATIONS Air Samples The following air sample locations failed to meet the requirement for "continuous sampler operation." As described in footnote (1) of procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program), Table 5-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons. /

VI. COMPARISON TO THE RADIOACTIVE EFFLUENT RELEASE PROGRAM As described in the section discussing radioisotopes found in fish from Coffey County Lake, dose that may be received as a* result of tritium released from WCGS is comparable with the theoretical doses calculated by the Radioactive Effluent Release Program.

The theoretical doses calculated by the Radioactive Effluent Release Program assume a person drinks the water from Coffey County Lake and eats the fish from Coffey County Lake. Based upon these assumptions the dose to man from both pathways was calculated to be 0.245 mRem for 2018.

Using sample data obtained from the REMP,. an adult drinking two liters per day of surface water from Coffey County Lake, using the average tritium activity (11,941 pCi/L), would receive a committed effective dose equivalent of 0.545 mRem per year. For an adult eating 21 kg of fish per y~ar from Coffey County Lake, using the average tritium activity (7,474 pCi/kg), would 2018 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 10 of 31

receive a committed effective dose equivalent of 0.010.mRem per year. Based upon the REMP

. results, the dose from both pathways was calculated to be 0.555 mRem per year.

It should be noted Coffey County Lake is* not used as a drinking water source. Calculating the dose to man for tritium detected in the Coffey County Lake su*rtace water is for comparison purposes only.

The tritium dose value.s are being compared on a qualitative basis. It is not expected that the annual doses, as calculated in the Radioactive Effluent Release Report, would compare directly to those calculated from the REMP. The Radioactive Effluent Release Report provides a "snap shot" of potential dose resulting from the year's releases.

The REMP data indicates the accumulated result of releasing tritium into the lake since the start of plant operation.,

APPENDIX A INTERLABORATORY AND INTRALABORATORY COMPARISON PROGRAM RESULTS Appendix A is updated four times a year..The complete appe_ndix is included in March, June, September and December monthly progress reports only.

January, 2018 through Dec~mber, 2018

Appendix A lnterlaboratory/ lntralaboratory 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.

Table A-1 lists results that were obtained through participation in the RAD PT Study Proficiency Testing Program administered by Environmental Resource 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. Acceptance criteria is detailed on Attachment A page A2.

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 analytical results from the in-house "duplicate" program for the past twelve months. The Precision Acceptance limit is +/-25% of the mean for Sr-89,90, Gross Alpha and Gross Beta or the 2-sigma uncertainty overlaps the mean value. For all other analytes the precision acceptance limit is

+/-20% of the mean.or the 2-sigma uncertainty overlaps the mean value.

Complete analytical data for duplicate analyses is available upon request.

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

I Table A-7 lists results that were obtained through participation in the MRAD PT Study Proficiency Testing Progra administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Asses~ment Program (EML).

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

b A transcription error caus_ed the Cs-137 result submitted to be understated by a factor of 10.

The actual result obtained was slightly higher than the acceptance criteria for the study.

A "Quick Response" proficiency test was analyzed to help determine the cause of the high result. (See ERW-3832 above)

No definitive cause for the previous high Cs-137 result was determined.

c An investigation is underway to determine the reason for the unacceptable Uranium PT result.

b Laboratory codes as follows: ERW (water), ERAP (air filter), ERSO (soil), ERVE (vegetation). Results are reported in units of pCi/L, except for air filters (pCi/Filter), vegetation and soil (pCi/kg).

c Results are presented as the known values, expected laboratory precision (2 sigma, 1 determination) and control limits as provided by ERA.

d Reported result was higher than ERA's upper acceptance limit. An investigation was initiated. The sample was run with a pre-treatment technique. Rerunning the analysis with this pre-treatment gave a *result of 7.30 pCi/total.

Going forward all samples for Am-241 will be analyzed utilizing this pre-treatment.

e The ERA results for K-40 and Bi-212 were outside the acceptable limits. The sample analysis was rerun utilizing a different library with acceptable results. The gamma software vendor will be consulted for the differences between the two libraries. In the meantime EIML will occasionally be counting a standard with known activity to ensure reported values are within the laboratory's acceptance criteria.

EXECUTIVE

SUMMARY

The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed in 2018 in accordance with AP 078-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)].

No program changes are necessary regarding milk locations. Again, no milk sampling locations were identified.

The two broad leaf vegetation locations with the highest calculated annual average D/Q rankings are A2.60-17TE1527 and Q2.35-MILA1619. Since these gardens are currently listed as sample locations for the Radiological Environmental Monitoring Program in procedure AP 078-004 (locations A-3 and Q-6), no program changes are necessary regarding broadleaf vegetation locations.

BACKGROUND Section 5.2, Attachment A, of procedure AP 078-004, directs that "a Land Use Census shall be conducted annually during the growing season to identify the nearest ( 1) milk animal, (2) residence, and (3) garden of greater than 500 square feet producing broadleaf vegetation in each of the 16 meteorological sections within five miles of the WCGS site."

Table 5-1, Attachment A, of procedure AP 078-004, requires that broadleaf vegetation samples be collected from "two indicator locations (using the criteria from the "Land Use Census" section) with highest calculated annual average 0/Q."

Table 5-1, Attachment A, of procedure AP 078-004, also requires that milk samples be collected from "three indicator locations within 5 miles of the site having the highest dose potential."

METHODOLOGY Over two hundred surveys were mailed to the rural residents living within five miles of WCGS.

The survey excluded the residents of New Strawn and Burlington.

These locations were excluded due to the large number of households and the low likelihood that information gained from these residences would affect the locations chosen for REMP sampling.

Drive-by information was collected for the nearest residences in each sector that did not return surveys.

The information collected was compiled and the results are identified in Tables 1-3.

Calculations were performed so that garden locations could be ranked by their respective D/Q.

These result$ are contained in Table 4.

RESULTS Three changes were identified for the nearest occupied residence in each sector. Six changes*

were noted for the nearest garden producing broadleaf vegetation. There were no changes regarding milk sample locations. Again, no locations were identified that milked animals for human consumption.
