INTRODUCTION The 2004 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December31, 2004. 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 Radiological Environmental Monitoring Program (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), results of sample analyses, a discussion of monitoring program results, a description of revisions to and deviations from the program, and the results of Interlaboratory Comparison Programs. Individual sample results and a summary of results in the Nuclear Regulatory Commission (NRC) Branch Technical Position specified format are included as appendices.

Plant-related activation, corrosion or fission products were not detected during 2004 in airborne particulate and radioiodine filters, ground water, drinking water, shoreline sediment, broadleaf vegetation, crops, terrestrial vegetation, aquatic vegetation, soil or deer samples. Activation, corrosion or fission products attributable to plant operation were detected during 2004 in surface water, fish, and bottom sediment samples.

Nuclides detected in REMP samples were below applicable NRC reporting levels, and program lower limits of detection were met.

Based upon the radiological environmental monitoring results, it was concluded that station.

operations has had no significant radiological impact on the health and safety of the public or the environment.

1. PROGRAM DESCRIPTION Radiological environmental samples were collected according to the schedule in WCGS procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program). Environmental samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc. Detroit Edison processed environmental thermoluminescent dosimeters (TLDs) at the Enrico Fermi 2 plant. Table 1 lists sampling pathways and frequencies of sampling and analysis. Table 2 lists each sample location's distance and direction from the plant. Samples in addition to those required by the WCGS Offsite Dose Calculation Manual (ODCM) were also obtained.

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

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 1 of 33

A. Airborne Pathway Low volume air sampling pumps collected particulate and radioiodine samples on 47 mm glass fiber filters and charcoal canisters, respectively. The filters and charcoal canisters were changed out weekly, labeled, and shipped to Environmental, Inc. for analysis. The volume of air sampled was calculated from the average of initial and final flow rates and the total time of collection. Each pump was equipped with a time totalizer that was checked weekly against the elapsed time to identify electrical power outages.

Gross beta analysis of the air particulate samples was performed after a nominal 72-hour period to allow the radon and thoron daughter products to decay.

Weekly air particulate filters were combined into quarterly composites for each location and analyzed for gamma emitting isotopes.

Charcoal canisters were routinely counted in groups of five to determine the presence or absence of 1-131. Positive indication of 1-131 would have resulted in analysis of each individual charcoal canister.

Air samples were collected from six locations. Indicator locations 2, 37 and 49 are located in the three sectors with the highest ground level deposition constants (D/Q). Air sampling stations are also located in the community of New Strawn (indicator location 32) and a control location at Harris (location 48). Supplemental indicator location (location 18) was also sampled during the year. Distances and directions to sampling locations from the plant are listed in Table 2, indicator locations are shown in Figure 1, and the control location is shown in Figure 5.

B. Direct Radiation Pathway Panasonic UD-814-AQ TLDs were used at 48 locations during the sample year. The TLDs consist of one lithium-borate element and three calcium sulfate elements in a plastic case.

TLDs were typically positioned roughly 3 to 4 feet above the ground in plastic thermostat boxes.

The thermostat boxes protect the TLDs from the elements and tampering. Two TLDs were placed at each designated location. The TLDs were changed out quarterly. Indicator TLD sample locations are illustrated in Figure 2 and control locations are shown in Figure 5. Table 2 provides the distance and direction of each location from the plant. Control locations were 39 (Beto Junction), 40 (Hartford) and 48 (Harris).

C. Waterborne Pathway All water samples were analyzed to determine whether gamma emitters were present. In addition to gamma isotopic analysis, radiochemical analysis for 1-131 was performed on drinking water and ground water samples. Gross beta analysis was also performed on drinking water samples. Tritium analysis was performed monthly by liquid scintillation for surface water and quarterly for drinking water. Tritium analysis was also performed quarterly on ground water samples. Water sampling locations are listed in Table 2 and are shown in Figures 3 and 5.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 2 of 33

Monthly grab samples of surface water were collected from John Redmond Reservoir (JRR) as a control location and from the spillway (SP) of Wolf Creek Lake (WCL) as an indicator location.

During 2004, the indicator location discharge cove (DC) was removed from the sampling program.

Quarterly grab samples of ground water were collected from four wells. Location B-12 is hydrologically up gradient from the site and was used as a control location. Three locations (C-10, C-49, and J-1) are hydrologically down gradient from the site and were used as indicator sample locations. Duplicate samples were obtained from location C-49 and were labeled L-49.

These duplicate samples served as laboratory quality checks.

Drinking water was sampled at the water treatment facilities for the towns of Burlington (control location BW-15), LeRoy (indicator location LW-40) and Neosho Falls (indicator location NF-DW). The Burlington facility is located upstream and the LeRoy and Neosho Falls facilities are located downstream of the confluence of the discharge from Wolf Creek Lake and the Neosho River. During January 2004, the LeRoy water treatment facility closed. Composite samples were obtained monthly from automatic samplers at each location that collected approximately 27 ml of drinking water every two hours.

Shoreline sediments were sampled semiannually. Gamma isotopic analysis was performed on the shoreline sediment samples. Shoreline sediment sample locations were the Wolf Creek Lake discharge cove (DC) indicator location and at the control location (JRR).

D. Ingestion Pathway Because no sampling locations that produce milk for human consumption were identified within five miles of the plant, milk was not collected during the sample year.

Fish were sampled semiannually from the tail waters of JRR (control, Figure 4) and from Wolf Creek Lake (indicator, Figure 4). Gamma isotopic analysis was 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 from five gardens. Three indicator (G-1, N-1 and Q-6) gardens (Figure 4) and two control (D-1 and D-2) gardens (Figure 5) were sampled. Gamma isotopic analyses were performed on all samples.

Crop samples were obtained from two indicator locations (NR-Dl and NR-D2) downstream of the confluence of Wolf Creek and the Neosho River. Two crop samples were obtained 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 ODCM)

Drinking water indicator location 1O-DW (lola) was sampled during the year. The drinking water sample was analyzed for gross beta, gamma emitters and 1-131. This sample location was added due to the anticipated closure of the Neosho Falls drinking water treatment facility and is identified on Figure 5.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 33

Shoreline sediments were collected at the Environmental Education Area (EEA) and the Make-up Water Discharge Structure (MUDS). Gamma isotopic analysis was performed on the shoreline sediment samples. These samples were collected as part of a cooperative sampling effort with the Kansas Department of Health and Environment (KDHE). The indicator sample locations are identified on Figure 3.

Bottom sediment samples were collected at the EEA and just east of the DC (E of DC).

Gamma isotopic analysis was performed on the bottom sediment samples. These indicator samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 3.

Bottom sediment samples were collected semiannually at the Wolf Creek Lake discharge cove (DC) indicator location and the control location (JRR). Gamma isotopic analysis was performed on the bottom sediment samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 3.

Aquatic vegetation was collected from indicator locations EEA, DC ALT and MUDS. Gamma isotopic analysis was 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 was sampled from indicator locations EEA and MUDS. Gamma isotopic analysis was performed on the terrestrial vegetation 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 indicator locations MUDS and EEA. Gamma isotopic analysis was performed on the soil samples. These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.

A road-killed deer was sampled from indicator location A1.68. Gamma isotopic analysis was performed on the deer sample. The sample was split with the KDHE. The sample location is identified on Figure 4.

Distance and direction information for the sampling locations listed in this section are outlined in Table 2.

II. DISCUSSION OF RESULTS Analysis results for all 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.

In this section, results are discussed by pathway and analysis type. Monitoring results are compared with control data, preoperational values, sources of radioactivity, and effluent releases when applicable. Trends or seasonal effects are discussed.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 33

A. Airborne Pathway Chart 1 graphically illustrates weekly gross beta results for the sample year. Chart 2 represents the historical smoothed averages of indicator and control gross beta data.

Charts 1 and 2 demonstrate how closely the indicator and control locations tracked together.

Chart 2 reveals a seasonal cyclic trend in which 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 2004 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/i 3. The 2004 weekly gross beta analyses range for indicator locations was 0.014 to 0.068 pCi/m 3, which was within the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2004 (0.029 pCi/M 3) 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 locations.

The annual mean for indicator locations for 2004 (0.029 pCi/M 3 ) was similar to the annual mean of the control locations (0.028 pCi/M 3).

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 pdi/m3 for indicator locations, and the annual mean for indicator locations was 0.069 pCi/M 3 . In 2004, the range for Be-7 detected activity was 0.057 to 0.094 pCi/mi3 for indicator locations, and the annual mean for indicator locations was 0.077 pCi/M 3.

The control location annual mean for Be-7 detected activity (0.076 pCi/M3 ) was similar to the indicator locations annual mean (0.077 pCi/i 3).

Required lower limits of detection were met and 1-131 activity was not detected in the weekly analysis of charcoal filters at any location.

No effects of plant operation were seen via the airborne pathway for the year, and no unusual trends were noted.

B. Direct Radiation Pathway Quarterly gamma exposures measured at each location are shown in Table 3. Measured values have been converted to a standard 90-day quarter.

The annual mean of all indicator locations in 2004 was 0.230 mR/day and the annual mean for the control locations was 0.223 mR/day. These results are similar to the pre-operational results for 1981. In 1981, the annual mean of all indicator locations was 0.21 mR/day and annual mean for the control locations was 0.19 mR/day.

Results from TLDs located near the plant (less than three miles), which would be most affected by changes in plant operation, were combined into quarterly averages. These nearsite averages, using locations 1, 2, 7-14, 18, 26-30, 37 and 38, are compared to control location 2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 33

results (locations 39, 40 and 48) in Chart 3. Chart 3 also includes preoperational data for comparison. The nearsite TLD locations have historically trended higher than the control locations both prior to and after WCGS became operational.

C. Waterborne Pathway (1) Surface Water Tritium, attributable to WCGS operation, was detected in all surface water samples collected from Wolf Creek Lake during 2004. An adult drinking 2 liters per day of surface water collected from the Wolf Creek Lake, using the annual mean of detected tritium activity (13,490 pCi/liter),

would receive a committed effective dose equivalent of 0.616 mRem per year. An adult drinking 2 liters per day of surface water collected from the Wolf Creek Lake, using the highest detected tritium activity (15,876 pCi/liter), would receive a committed effective dose equivalent of 0.725 mRem per year. It should be noted that Wolf Creek Lake is not a drinking water source.

Chart 4 illustrates the yearly averages of surface water tritium data for the spillway location. It can be seen in Chart 4 that surface water tritium concentrations have trended upward since plant startup. This is expected until the average tritium concentration of the lake reaches equilibrium.

Required lower limits of detection were met and tritium activity was not detected in samples obtained from the control location (JRR).

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

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

(2) Ground Water Required lower limits of detection were met and radioactivity was not detected in any ground water samples.

(3) Drinking Water Chart 5 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 locations.

Gross beta activity was detected in all drinking water samples. The annual mean of the control location gross beta activity (4.3 pCi/liter) was equal to the annual mean of the indicator locations (4.3 pCi/liter). The 2004 annual means of gross beta activity for both the control and indicator locations were lower than those of the pre-operational monitoring year of 1984. In 1984, the annual mean of the control location gross beta activity was 6.4 pCi/liter, and the annual mean of the indicator location gross beta activity was 7.5 pCi/liter.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 33

Required lower limits of detection were met. Tritium activity was not detected in any drinking water samples. Additionally, radionuclides were not detected by the 1-131 or gamma isotopic analyses.

Activity due to plant operation was not evident in drinking water samples during 2004 and no unusual trends were noted.

(4) Shoreline Sediment Naturally occurring K-40 was detected in samples obtained from indicator locations (10,309-12,688 pCi/kg, dry) and in samples obtained from control locations (7,948-10,666 pCi/kg, dry).

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

Required lower limits of detection were met and K-40 was the only activity detected.

Activity due to plant operation was not evident in shoreline sediment samples during 2004 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 Land Use Census.

(2) Fish Naturally occurring K-40 activity was detected in all fish samples. K-40 activity was also detected during pre-operational fish monitoring.

During 2004, fish were also analyzed for tritium. All fish samples taken from Wolf Creek Lake had tritium activity detected (7,790.9 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 for 2004 (8,942 pCi/kg), would receive a committed effective dose equivalent of 0.012 mRem.

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

No other radionuclides were detected in fish during the year. The ODCM 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 locations detected naturally occurring gamma emitters Be-7 and K-40. Be-7 and K-40 activity were also detected pre-operationally.

The ODCM required lower limits of detection were met and no unusual trends were noted.

Activity attributable to plant operation was not detected.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 33

(4) Crop Samples Gamma analysis detected naturally occurring K-40 to be present in all of the samples. K-40 activity was also detected during pre-operational crop monitoring. K-40 was the only activity detected in crop samples. The ODCM required lower limits of detection were met and no unusual trends were noted.

E. Additional Samples Collected (not required by ODCM)

(1) Bottom Sediment Naturally occurring K-40 was detected in all of the bottom sediment samples. K-40 activity was also detected during pre-operational bottom sediment monitoring.

Co-58 activity (34.7 pCi/kg) was detected in one sample obtained from the Wolf Creek Lake discharge cove. Co-58 activity was attributable to plant operation and has been identified in plant effluents. Co-58 activity was not detected in pre-operational environmental monitoring and was not detected in samples collected from control location JRR during 2004.

Co-60 activity (153.8 and 179.4 pCi/kg) was detected in the samples obtained from the Wolf Creek Lake discharge cove and from a sample obtained just east of the discharge cove (243.3 pCi/kg). Co-60 activity was attributable to plant operation and has been identified in plant effluents. Co-60 activity was not detected in pre-operational environmental monitoring and was not detected in samples collected from control location JRR during 2004. Chart 6 plots the Co-60 detected activity from the discharge cove and reflects a decreasing trend.

Cs-137 activity (202.1 and 201.3 pCi/kg) was detected in the indicator samples obtained from the Wolf Creek Lake discharge cove and from a sample obtained just east of the discharge cove (217.1 pCi/kg). A portion of this activity is due to fallout and a portion of this activity is likely plant-related since Cs-134 activity has been detected in the past. Cs-137 activity was detected in pre-operational samples, and the results for 2004 indicator bottom sediment samples were 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 46 to 550 pCi/kg.) Cs-137 activity has been identified in plant effluents. Cs-137 activity (161.1 and 115.5 pCi/kg) was also detected in the control location samples and in the sample obtained from the indicator location EEA (119.0 pCikg).

Chart 7 plots the Cs-137 detected activity from the discharge cove indicator location and JRR control location bottom sediment samples. The detected Cs-137 activity measured from the discharge cove location reflects a decreasing trend. The Chart 7 trend line indicates that as expected, Cs-1 37 activity detected at the JRR control location has been decreasing.

Cs-134 activity was not detected in 2004 discharge cove bottom sediment samples; however, Chart 8 has been included to display the decreasing trend.

No other radionuclides were detected in bottom sediment samples and no unusual trends were noted.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 33

(2) Aquatic Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2004. Be-7 and K-40 activity were also detected during pre-operational monitoring.

No other radionuclides were detected in aquatic vegetation samples and no unusual trends were noted.

(3) Terrestrial Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2004. No other radionuclides were detected. No unusual trends were identified.

(4) Soil Naturally occurring K-40 activity was detected in both of the soil samples. K-40 activity was also detected during pre-operational soil monitoring.

Cs-137 (295.2 and 413.3 pCi/kg) activity was detected in the soil samples. The pre-operational Cs-137 results (255 to 2,160 pCi/kg) for soil samples were decay corrected. The decay corrected pre-operational range is approximately 161 to 1360 pCi/kg. The measured Cs-137 activity of the soil samples obtained during 2004 are within the decay corrected pre-operational range. Cs-137 activity was not detected in air samples collected during 2004. The measured Cs-137 activity in the soil sample was likely due to previous fallout and not to a recently produced fission product associated with plant operation.

No unusual trends were identified.

5) Deer Gamma analysis detected naturally occurring K-40 (3378.1 pCi/kg wet) activity in the deer sample obtained from indicator location A1.68. K-40 activity was also detected during pre-operational monitoring. K-40 was the only activity detected in the deer sample. No unusual trends were noted.

111. PROGRAM REVISIONS/CHANGES The indicator surface water sample location was changed from the discharge cove (DC) to the spillway (SP) of Wolf Creek Lake. The justification for the change was that surface water sampled from the discharge cove was not "representative" of the cooling lake water, especially if a release was in progress.

TLD location 34 was moved due to safety concems. The change was made after a comparison was completed which reflected that no significant difference existed between the two locations.

TLD location 40 was removed from the program. A comparison was made between TLD results at location #40 (Hartford) and location #48 (Harris). No significant difference was identified.

Based upon Engineering Calculation AN-03-026, air sample station 49 and TLD location 49 were added to the sample program.

Drinking water sample location LW-40 (LeRoy) was removed from the sample program since the City of LeRoy stopped obtaining their drinking water directly from the Neosho River.

Drinking water sample location NF-DW (Neosho Falls) was added to the ODCM.

(Supplemental sampling at this location started in December 2002.)

Based upon the results of the 2003 Land Use Census and cooperator participation, the following broadleaf vegetation garden changes for indicator locations were made during 2004:

  • Garden location H-1 was deleted from the program
  • Garden location Q-6 was added to the program IV. PROGRAM DEVIATIONS Air Samples The air sample locations listed below failed to meet the requirement for Ucontinuous sampler operation." As described in footnote (1) of AP 07B-004, Table 5-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons. Discrepancies greater than five percent between Total Military Time and Total Meter Time, which resulted in a loss of air sample collected, are listed in the following table.

Location Sample Period Percent Explanation of Deviation Discrepancy/

Hours Unavailable 49 06/02/04 - 06/09/04 6.02/10.2 Construction Power Loop Outage 48 06/16/04 - 06/23/04 7.44/12.5 Electrical Power Outage 49 06/16/04 - 06/23/04 65.46/110.1 Breaker turned off for Security Mod 2 12/08/04 - 12/15/04 Unk/-82.4 Air Sample Pump Motor Seized 49 12/15/04 - 12/21/04 19.26/29 Breaker turned off for Maint on Board 2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 10 of 33

During 2004, no other deviations from the AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program) sampling schedule occurred.

V. INTERLABORATORY COMPARISON PROGRAM RESULTS During 2004, Environmental, Inc. was contracted to perform radiological analysis of environmental samples for WCNOC. The lab participated in the Environmental Resource Associates (ERA) Proficiency Testing Program. Appendix A is the Interlaboratory Comparison Program Results for Environmental, Inc. TLD intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also contained in Appendix A.

Table 4 is a summary of statistical results of performance testing of TLDs processed at Enrico Fermi 2 by Detroit Edison, which participated in the National Voluntary Laboratory Accreditation Program.

VI. COMPARISON TO THE RADIOACTIVE EFFLUENTS RELEASE PROGRAM As described in the sections discussing radioisotopes found in the surface water from Wolf Creek Lake, dose that may be received as a result of tritium released from WCGS is consistent with the theoretical doses calculated by the Radioactive Effluent Release Program.

Chart 9 indicates that the dose to a man resulting from drinking surface water from Wolf Creek Lake was within a reasonable expected value. Dose for the surface water was determined using the December tritium activity detected for each calendar year. Released tritium maximum organ dose (mRem) values were obtained from Annual Radioactive Effluent Release Reports and are not cumulative (i.e., the values reflected are the totals for the respective years).

An adult drinking 2 liters per day of surface water collected from Wolf Creek Lake, using the 2004 December detected tritium activity (13,429 pCi/liter), would receive a committed effective dose equivalent of 0.613 mRem per year. This information was derived from radiological environmental monitoring.

The maximum organ dose for tritium released in liquid effluents in 2004 was 0.117 mRem. This information was obtained from the Annual Radioactive Effluent Release Report.

The tritium dose values are being compared on a qualitative basis. It is not expected that the annual doses, as calculated in the Annual Radioactive Effluent Release Report, would compare directly to those calculated from the REMP. The Annual Radioactive Effluent Release Report provides a 'snap shot' of potential dose resulting from the year's releases. The REMP data indicate the accumulated result of releasing tritium into the cooling lake since the start of plant operation.

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

January through December, 2004

Appendix A Interlaboratorv Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply.environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

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

The results in Table A-2 list results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

Table A-3 lists results of the analyses on in-house 'spiked" samples for the past twelve months. All samples are prepared using NIST traceable'sources. Data for previous years available upon request.

Table A-4 lists results of the analyses on in-house 'blank' samples for the past twelve months. Data for previous years available upon request. request.

Table A-5 list results of the in-house 'duplicate' program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.

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

The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

Attachment A lists acceptance criteria for "spiked" samples.

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

Midwest Laboratory as a participant in the Department of Energy's Mixed Analyte Performance Evaluation Program, Idaho Operations office, Idaho Falls, Idaho b All results are in Bqlkg or Bq/L as requested by the Department of Energy.

d MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP.

d The cause of the deviation seems to be incomplete dissolution of the sample.

A spiked soil sample was prepared. Known activity; 32.98 pCilg; laboratory result 33.47 pCig.

'The sample was reanalyzed with the same results. Investigation is in progress.

g Based on the results of gamma emitting isotopes (Cs-137 and Co-60), the filter geometry appears to be biased by -10%. Addition of the summation peak at 1400 KeV results In a recalculation of 2.12 i 0.15 Bq/sample.

EXECUTIVE

SUMMARY

The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed for 2004 in accordance with AP 07B-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)]. Changes are not required for the Radiological Environmental Monitoring Program (REMP) broadleaf vegetation sample locations for 2005. The two broadleaf vegetation locations with the highest calculated annual average D/Q rankings are GI.56-QURD1384 and Q2.35-MILA1619. AP 07B-004 specifies that an "alternate location may be used to provide continued monitoring". The third-ranked garden is location Fl.76-14RD1730. Since the established sample location at N2.38-RRDR9 is the fourth ranked garden and the D/Q difference is less than 20%, N2.38-RRDR9 will continue to be the alternate sample location.

BACKGROUND Section 5.2, Attachment A, of the ODCM 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" and "the results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report."

Table 5-1, Attachment A, of the ODCM (AP 07B-004) requires that broadleaf vegetation samples be collected from "two indicator locations with highest calculated annual average D/Q."

Table 5-1, Attachment A, of the ODCM (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 One hundred eighty-five surveys were mailed to the rural residents living within five miles of WCGS. A follow-up survey was sent to residents who did not respond. The survey excluded the residents of New Strawn, Burlington, and a trailer park north of 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 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 DIQ.

These results are contained in Table 4.

2004 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page D - 2

RESULTS NOTE: A Global Positioning System was used to verify residence distances and sectors.

As identified in Table 2, no sectors experienced a change in the nearest residence.

Seven location changes were noted for the nearest garden producing broadleaf vegetation.

These changes are identified in Table 3.

There were no changes regarding milk locations. Again, no locations were identified that produced milk for human consumption.
