2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 1 of 32 EXECUTIVE
SUMMARY
Plant-related activation, corrosion, or fission products were not detected during 2023 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 2023 in surface water, fish, turkey, and deer samples.
Nuclides detected in Radiological Environmental Monitoring Program (REMP) samples were below applicable Nuclear Regulatory 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 2023 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2023. WCGS is 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 Interlaboratory Comparison Program and a comparison to the Radioactive Effluent Release Program. The Interlaboratory 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 07B-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 07B-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
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 2 of 32 the air particulate filters. Radioiodine canisters were analyzed weekly for I-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.
B. Direct Radiation Pathway Optically stimulated luminescence (OSL) dosimeters were used continuously at 44 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 20th Road and Yearling Road).
C. Waterborne Pathway Gamma isotopic analysis was performed on the water samples. In addition to gamma isotopic analysis, analysis for I-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 Reservoir (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 B-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 IO-DW) and Burlington (control sample location BW-15). The Iola facility is located downstream of the Neosho River-Wolf Creek confluence and the Burlington facility is located upstream of the Neosho River-Wolf Creek confluence. Composite samples were obtained monthly from automatic samplers at each location. The automatic drinking water samples collected approximately 27 milliliters of water every two hours.
Shoreline sediments were sampled semiannually. Gamma isotopic analyses were performed on the shoreline sediment samples. Shoreline sediment sample locations were the Coffey County Lake discharge cove (DC) indicator location and the John Redmond Reservoir (JRR) control location.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 32 D. Ingestion Pathway Milk was not collected during the sample year. The Land Use Census did not identify any locations producing milk for human consumption within five miles of the plant.
Fish were sampled semiannually from the indicator sample location Coffey County Lake (CCL) and from the tail waters of John Redmond Reservoir (JRR) control sample location. These sample locations are identified in Figure 4. Gamma isotopic analyses were performed on the boneless meat portions of the fish. Several species of game fish and rough fish were sampled.
Fish were also analyzed for tritium.
Broadleaf vegetation samples were collected monthly when available during the growing season. Indicator (A-3, B-1, H-2 and Q-6) location gardens (Figure 4) and a control (D-2) location garden (Figure 5) were sampled. Gamma isotopic analyses were performed on these samples.
Irrigated crop samples were obtained from indicator location (NR-D1) and non-irrigated samples from indicator location (NR-D2) downstream of the confluence of Wolf Creek and the Neosho River. Irrigated crops were also sampled from control location (NR-U1). Gamma isotopic analysis was performed on each sample. Crop sample locations are identified on Figure 5.
E. Additional Samples Collected (not required by AP 07B-004)
Bottom sediment samples were collected semiannually from indicator sample locations at the Discharge Cove (DC), and the control sample location at John Redmond Reservoir (JRR).
Three other bottom sediment samples were collected from Makeup Discharge Structure (MUDS), Environmental Education Area (EEA), and Stringtown Cemetery (SC).
Gamma isotopic analyses were performed on the bottom sediment samples. Two samples collected from indicator location (DC) were also analyzed for Fe-55. No samples were analyzed for Ni-63, Sr-89 and Sr-90 activity (Hard to Detect Metals). One shoreline sediment sample was collected from indicator sample location at Stringtown Cemetery as part of a cooperative sampling effort with the Kansas Department of Health and Environment (KDHE). The sample locations are identified on Figure 3.
Aquatic vegetation was collected from indicator locations at the Makeup Discharge Structure (MUDS), Environmental Education Area (EEA) and Stringtown Cemetery (SC). Gamma isotopic analyses were performed on the aquatic vegetation samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 3.
Terrestrial vegetation (grass) was sampled from the Environmental Education Area (EEA) and the Makeup Discharge Structure (MUDS) indicator sample locations. Gamma isotopic analysis was performed on the grass samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.
Soil was sampled from the Makeup Discharge Structure (MUDS). Gamma isotopic analysis was performed on the soil sample. This sample was collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 32 Turkey was sampled from indicator sample location J3.5. Gamma isotopic analysis and tritium analysis were performed on the turkey sample. This sample was collected as part of a cooperative sampling effort with the KDHE. The sample location is identified on Figure 4.
Deer was sampled from indicator sample location Q2.4. Gamma isotopic analysis and tritium analysis were performed on the deer sample. This sample was collected as part of a cooperative sampling effort with the KDHE. The sample location is identified on Figure 4.
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 2023 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 2023 weekly gross beta analyses range for indicator locations was 0.015 to 0.051 pCi/m3. The 2023 weekly gross beta analyses range was within the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2023 (0.030 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 2023 (0.030 pCi/m3) was the same as the controlled location (0.030 pCi/m3). The indicators location with the highest gross beta annual mean was 49, the annual mean of this location was (0.030 pCi/m3). This is the same annual mean as the controlled location (0.030 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 2023, the range for Be-7 detected activity was 0.058 to 0.112 pCi/m3 for indicator locations and the annual mean for indicator locations was 0.084 pCi/m3. The control location annual mean for Be-7 detected activity (0.077 pCi/m3) was lower than the annual mean of the indicator locations (0.084 pCi/m3). The indicator location with the highest annual mean of detected Be-7 activity was location 32 (0.091 pCi/ m3).
I-131 activity was not detected in the weekly analysis of radioiodine canisters at any location.
II. DISUSSION OF RESULTS
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 32 The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2023 in air particulate filters and radioiodine canisters. No unusual trends were noted.
B. Direct Radiation Pathway Quarterly OSL 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 2023 was 19.0 mR per standardized 90-day quarter. The annual mean of the control sample locations in 2023 was 19.0 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 22 (22.5 mR per standardized 90-day quarter) which is slightly higher than the annual mean of the control sample locations (19.0 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 increased during 2010 based on how transit dosimeters are handled. Condition Report 00128355 was written to reduce data elimination based on standard deviation starting in Quarter 3 of 2018. Chart 3 displays how closely the indicator and control location OSL dosimeter results are since 2018. In 2023 no change in trend was noted due to this change.
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. The dip in the graph in 2021 was due to the dosimeters not being picked up by UPS for delivery to vendor lab 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 13,003 pCi/L and the range was 12,098 to 14,167 pCi/L.
The detected tritium activity was below the 30,000 pCi/L AP 07B-004 reporting level. Chart 5 illustrates the yearly average of surface water tritium data for the SP location. Chart 5 indicates the average tritium concentration of the SP location stayed the same through out the year.
No Tritium activity was detected in the controlled sample, John Redmond Reservoir (JRR).
During pre-operational radiological environmental monitoring, measured radiological activity was not detected in surface water samples.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 32 The AP 07B-004 required lower limits of detection were met. Radionuclides were not detected by the gamma isotopic analyses or by Fe-55 analyses.
Tritium was the only activity detected during 2023 in surface water samples and no unusual trends were noted.
(2) Ground Water The AP 07B-004 required lower limits of detection were met for I-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 2023 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 (3.674 pCi/L) was slightly higher when compared to the annual mean of the control sample location gross beta activity (2.750 pCi/L). The 2023 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 6.4 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. The spike in March is suspect to vendor error. Compared to both historical and current trends, Wolf Creek has never had a result that high.
No tritium was detected in the indicator sample location during 2023. 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 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2023 in drinking water samples. The only unusual trend was the abnormal gross beta result in March.
(4) Shoreline Sediment Naturally occurring K-40 was detected in shoreline sediment samples collected from the DC (indicator sample location),
JRR (control sample location),
and EEA (Environmental Education Area. K-40 was also detected during pre-operational shoreline sediment monitoring.
No other radionuclides were detected in the DC, EEA, SC, or JRR shoreline sediment samples during 2023. The AP 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2023 in shoreline sediment samples and no unusual trends were noted.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 32 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 2023 Land Use Census.
(2) Fish Naturally occurring K-40 activity was detected in fish samples obtained from 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 annual mean (9,197 pCi/kg). The detected tritium activity was attributable to plant operation. An adult consuming 21 kilograms of fish, at the maximum measured tritium concentration (10,538 pCi/kg), would receive a committed effective dose equivalent of 0.014 mRem.
Tritium activity was not detected in the control location samples collected from JRR.
No other radionuclides were detected in fish samples during 2023. The AP 07B-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 Be-7 and K-40. Be-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 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2023 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 07B-004 required lower limits of detection were met. Plant-related activation, corrosion, or fission products were not detected during 2023 in crop samples and no unusual trends were noted.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 32 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 pre-operational samples. The Cs-137 activity detected in 2023 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 29 to 361 pCi/kg.
The detected Cs-137 activity in the sample 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 two samples obtained from indicator sample locations.
No other radionuclides were detected in bottom sediment samples. Plant-related activation, corrosion, or fission products were not detected during 2023 in bottom 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 2023 in aquatic vegetation samples and no unusual trends were noted.
(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 2023 in terrestrial vegetation and no unusual trends were noted.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 9 of 32 (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 in one sample location in 2023. The detectable value is (169 pCi/kg).
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 97 to 820 pCi/kg. The detected Cs-137 activity in soil sampled in 2023 is below and within the decay corrected pre-operational range.
Plant-related activation, corrosion, or fission products were not detected during 2023 in soil samples and no unusual trends were noted.
(5) Turkey (Ingestion Pathway)
Naturally occurring K-40 activity was detected in the turkey sample obtained from the indicator location.
Tritium activity (738.0 pCi/kg) was 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 738.0 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 identified (6) Deer (Ingestion Pathway)
Naturally occurring K-40 activity was detected in the deer sample obtained from the indicator location.
Tritium activity (2,189 pCi/kg) was also detected in the deer sample. The detected tritium activity was attributable to plant operation.
An adult consuming 72.6 kilograms of deer meat, at the measured tritium concentration (2,1889 pCi/kg), would receive a committed effective dose equivalent of 0.010 mRem.
No other radionuclides were detected in the deer sample. No unusual trends were identified.
III. PROGRAM REVISIONS/CHANGES No revisions or changes were made to AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program) during 2023.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 10 of 32 IV. PROGRAM DEVIATIONS Air Samples There was no air sample locations t h a t failed to meet the requirement for continuous sampler operation in 2023. 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.
Ground Water Protection The following information is being provided in association with the Nuclear Energy Institute (NEI) Groundwater Protection Industry Initiative:
Describe offsite ground water or surface water sample results that exceeded the REMP reporting criteria that were voluntarily communicated to State/Local officials during the calendar year - None.
V. INTERLABORATORY COMPARISON PROGRAM Environmental, Inc., Midwest Laboratory merged to Microbac Laboratories Inc. in 2023. We continued our contract with them to perform radiological analysis of environmental samples for WCNOC. The laboratory participated in the intercomparison studies administered by Environmental Resource Associates, Inc. Appendix A is the Interlaboratory Comparison Program Results for Microbac Laboratories Inc. Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also contained in Appendix A.
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 0.092 mRem for 2023.
Using sample data obtained from the REMP, an adult drinking 2 liters per day of surface water from Coffey County Lake, using the average tritium activity (10,538 pCi/L), would receive a committed effective dose equivalent of 0.594 mRem per year. For an adult eating 21 kg of fish per year from Coffey County Lake, using the average tritium activity (9,197 pCi/kg), would receive a committed effective dose equivalent of 0.012 mRem per year. Based upon the REMP results, the dose from both pathways was calculated to be 0.606 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 surface water is for comparison purposes only.
2023 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 11 of 32 The tritium dose values 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 snapshot 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.

NOTE:
Appendix A is updated four times a year. The complete appendix is included in March, June, September and December monthly progress reports only.
January, 2023 through December, 2023 APPENDIX A INTERLABORATORY AND INTRALABORATORY COMPARISON PROGRAM RESULTS
A-1 Microbac Laboratories Inc. has participated in interlaboratory comparison (crosscheck) programs since the formulation of its 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 laboratorys 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 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 intralaboratory 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 intralaboratory blank samples for the past twelve months. Data for previous years available upon request.
Table A-5 lists analytical results from the intralaboratory duplicate program for the past twelve months. Acceptance is based on each result being within 25% of the mean of the two results or the two sigma uncertainties of each result overlap.
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 Resource Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).
Attachment A lists the laboratory acceptance criteria for various analyses.
Out-of-limit results are explained directly below the result.

TLD's were read and the results were submitted by Microbac Laboratories, Inc. to the University of Wisconsin-Madison Radiation Calibration Laboratory for comparison to the delivered dose.
b Reported dose was converted from exposure (R) to Air Kerma (cGy) using a conversion of 0.876. Conversion from air kerma to ambient dose equivalent for Cs-137 at the reference dose point H*(10)Ka = 1.20. mrem/cGy = 1000.
c Performance Quotient (P) is calculated as ((reported dose - conventionally true value) ÷ conventionally true value) where the conventionally true value is the delivered dose.
d Acceptance is achieved when neither the absolute value of the mean of the P values, nor the standard deviation of the P values exceed 0.15.

2023 Land Use Census Report 1
EXECUTIVE
SUMMARY
The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed in 2023 in accordance with AP 07B-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 broadleaf 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 07B-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 07B-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 07B-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 D/Q.
Table 5-1, Attachment A, of procedure AP 07B-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. Also used Google Earth/Maps to obtain images of properties.
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 results are contained in Table 4.

RESULTS No changes were identified for the nearest occupied residence in each sector. Eight changes were noted for the nearest garden producing broadleaf vegetation. These changes are identified as an underlined entry in the Tables. There were no changes regarding milk sample locations.
Again, no locations were identified that milked animals for human consumption.
