==SUMMARY== | |||
This Annual Radioactive Effluent Release Report (Report # 35) documents the quantities of liquid and gaseous effluents and solid waste released by Wolf Creek Generating Station (WCGS) from January 1, 2011 through December 31, 2011. The format and content of this report are in accordance with Regulatory Guide 1.21, Revision 1, "Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants." Sections 1, 11, III, and IV of this report provide information required by NRC Regulatory Guide 1.21 and Section 7.2 of AP 07B-003,"Offsite Dose Calculation Manual" (ODCM).Section I --- Section I contains, in detail, the quantities of radioactive liquid and gaseous effluents and cumulative dose summaries for 2011, tabulated for each quarter and for yearly totals.Specific ODCM effluent limits and dose limits are also listed in Section I, along with the percentage of the effluent limits actually released and the percentages of the dose limit actually received. | |||
No effluent or dose limits were exceeded during 2011.An elevated release pathway does not exist at WCGS. All airborne releases are considered to be ground level releases. | |||
The gaseous pathway dose determination is met by the WCGS ODCM methodology of assigning all gaseous pathways to a hypothetical individual residing at the highest annual X/Q and D/Q location, as specified in the ODCM. This results in a conservative estimate of dose to a member of the public, rather than determining each pathway dose for each release condition. | |||
A conservative error of thirty percent has been estimated in the effluent data.As stated above, no ODCM dose limits were exceeded in 2011.Section II --- Section II includes supplemental information on continuous and batch releases, calculated doses, and solid waste disposal. | |||
There were 49 gaseous batch releases in 2011 versus 42 in 2010. There were 59 liquid batch releases in 2011 versus 42 in 2010. WCGS released 0.005 curies in liquid releases during 2011 versus 0.011 curies in 2010, excluding gas and tritium. Continuous release pathways remained the same as previous years and all continuous releases were monitored. | |||
The report contains information on the following Condition Reports (CR): CR-42403 -ODCM surveillance was late due to monthly composites being completed after the late date.The report contains information on Carbon-14 evaluation. | |||
The report contains information on Nickel-63 study.Section III --- Section III documents WCGS meteorological data for wind speed, wind direction, and atmospheric stability. | |||
Section IV --- Section IV documents unplanned and abnormal releases, changes to radwaste treatment systems, land use census, monitoring instruments, radwaste shipments, and storage tank quantities. | |||
There were no unplanned, unmonitored releases in 2011.Changes to the land use census are noted. No changes or events occurred with monitoring instruments, radwaste shipments, and storage units. | |||

Batch Releases A batch release is the discontinuous release of gaseous or liquid effluents, which takes place over a finite period of time, usually hours or days.There were 49 gaseous batch releases during the reporting period. The longest gaseous batch release lasted 9,108 minutes, while the shortest lasted 56 minutes. The average release lasted 587 minutes with a total gaseous batch release time of 28,775 minutes.There were 59 liquid batch releases during the reporting period. The longest liquid batch release lasted 272 minutes, while the shortest lasted 55 minutes. The average release lasted 131 minutes with a total liquid batch release time of 7,741 minutes.6. Continuous Releases A continuous release is a release of gaseous or liquid effluent, which is essentially uninterrupted for extended periods during normal operation of the facility. | |||
Four liquid release pathways were designated as continuous releases during this reporting period: Steam Generator Blowdown, Turbine Building Sump, Waste Water Treatment, and Lime Sludge Pond. Two gas release pathways were designated as continuous releases: | |||
Unit Vent and Radwaste Building Vent.7. Doses to a Member of the Public from Activities Inside the Site Boundary Four activities by members of the public were considered in this evaluation: | |||
personnel making deliveries to the plant, workers at the William Allen White Building located outside of the protected area boundary, the use of the access road south of the Radwaste Building, and public use of the cooling lake during times when fishing was allowed. The dose calculated for the maximum exposed individual for these four activities was as follows: Plant Deliveries 3.86E-01 mRem William Allen White Building Workers 8.36E-03 mRem Access Road Users 3.96E-03 mRem Lake Use 4.96E-02 mRem The plant delivery calculations were based on deliveries 3 hours per week for 50 weeks per year. The William Allen White Building occupancy was based on normal working hours of 2000 per year. The usage factor for the access road south of the Radwaste Building was 25 hours per year. The dose to fishermen on the lake was based upon 3,504 hours (12 hours a day for 292 days, based on the number of days that the lake was open to fisherman). | |||
Pathways used in the calculation were gaseous inhalation, submersion, and ground plane. All calculations were performed in accordance with the methodology and parameters in the ODCM.8. Additional Information CR- 42403 -The July monthly liquid effluent composites were completed after the late date of August 7, 2011. Composites are due the 1st of each month, with a 25% grace period. All the necessary samples were available to make the composites, but there were no qualified technicians on site to perform the required calculations and preparations once it was recognized that composites were not done. Composites were completed satisfactorily on the next working day that qualified technicians were available, which was 21 of 57 August 8, 2011. This resulted in an Offsite Dose Calculation Manual surveillance being completed late. New surveillances were created and included in the site surveillance program to try to alleviate further instances of this happening. | |||
Carbon-14 (CR 36059)Regulation 10CFR50.36a requires nuclear power plants to report quantities of principal radionuclides in the annual radioactive effluent release report. In the early 1980s, the NRC decided that C-14 radionuclide would not be required to be reported because it would not make a significant contribution to dose. Since this time, technology has advanced both for effluent isotopic reduction and isotope detection and estimation. | |||
It is more likely the C-14 meets the definition of a principal radionuclide in accordance with the newly published Regulatory Guide 1.21 Revision 2 (June 2009).The NRC allows the reporting of this isotope based on estimation methods. EPRI TR 1021106 developed an estimation method based on peer-reviewed research that incorporates parameters of Wolf Creek's reactor design to estimate the gross amount of C-14 produced annually. | |||
This value is fed into additional calculations, based on Regulatory Guide 1.109, Calculation of Annual Doses to Man From Routine Releases of Reactor Effluents For the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I, to provide an estimation of annual dose. Based on the 2010 theoretical calculations and assuming the maximum percentage of inorganic C-14 compounds (30%), Wolf Creek has estimated the annual release of C-14 to be 10.7 curies and to contribute maximum dose values of 1.30 mrem/yr child bone dose and 0.259 mrem/yr child total body. This is well below the 1OCFR50, Appendix I, ALARA design objective of 15 mrem/yr. Additionally, this value is on par with the dose expected from naturally occurring radiocarbon. | |||
Nickel-63 Study Regulation 1OCFR50.36a requires nuclear power plants to report quantities of principal radionuclides in the annual radioactive effluent release report. To meet this requirement, periodic monitoring of potential isotopes in the waste streams is performed and any findings evaluated. | |||
Wolf Creek is not currently required by the ODCM to monitor for Ni-63 in the liquid effluents. | |||
However, to determine if Ni-63 is present in the liquid effluents, all 4 th quarter liquid composites were analyzed for the nuclide. The Batch composite resulted in positive values of Ni-63. The remaining composites, Steam Generator Blowdown to the Lake, Waste Water Treatment, Turbine Building Sump and Lime Sludge Pond, were all none detected.Using the Ni-63 detected in the quarterly Batch composite, the amount released for the year was conservatively estimated using the total liquid batch volume released and the total release duration for the year. Based on these estimates, Wolf Creek would release approximately 4.5E-04 mRem/year adult bone dose, which was the highest organ affected. | |||
Compared to 2.2E-01 mRem/year, which is the dose due to the highest organ for the year (adult Gi-LLI), the estimated Ni-63 bone dose is a minimal contributor. | |||
This estimation is well below the 1OCFR50, Appendix I limit of 10 mRem/year to any organ. | |||

35 of 57 8. NEI Groundwater Protection Industry Initiative ONSITE GROUNDWATER PROTECTION PROGRAM MONITORING Objective The objective of onsite groundwater protection program monitoring is to detect potential leaks of radioactivity from systems, structures, or components to the groundwater. | |||
At the Wolf Creek Generating Station, some background tritium influences from lake water are normal and expected.Basis The onsite groundwater protection program monitoring sample results are being reported in the Radioactive Effluent Release Report per guidance received in association with the Nuclear Energy Institute (NEI) Groundwater Protection Industry Initiative. | |||
The following information is also being reported in association with the NEI 07-07 Groundwater Protection Industry Initiative: | |||
: 1. Describe any onsite licensed radioactive materials releases or spills that were voluntarily communicated to State/Local officials during the calendar year. -None 2. Describe any onsite groundwater sample results that exceeded the reporting thresholds that were voluntarily communicated to State/Local officials during the calendar year. -None Onsite Groundwater Protection Program Monitoring Description In March of 2006, Wolf Creek Generating Station (WCGS) established an onsite groundwater protection monitoring program. During 2008, thirteen monitoring wells were added to the onsite groundwater protection monitoring program. The onsite groundwater protection program monitoring is implemented via procedure Al 07-007, Onsite Groundwater Protection Program Monitoring. | |||
The onsite groundwater samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc., Midwest Laboratory. | |||
Onsite groundwater samples were collected quarterly and were analyzed by gamma isotopic analysis, radiochemical analysis for 1-131 and tritium analysis. | |||
The vendor lab participated in an interlaboratory comparison program. The following tables describe the sample locations, the lower limits of detection and the reporting levels for radioactivity detected. | |||

This has been attributed to the Plant's reuse of tritiated lake water, and consistent with gaseous tritium deposition during normal operation. | |||
Lake water is used for plant cooling, which includes essential service water, and in the Fire Protection System. The location with the highest level of tritium detected was WEST ESW-W (2,097 +/- 154 pCi/L), which likely resulted from direct lake water inputs from an essential service water pipe leak. The leak has since been repaired. | |||
The measured tritium levels are significantly lower than the tritium levels routinely detected in surface water collected from Coffey County Lake (2011 range was 9,847 to 15,523 pCi/L). Tritium activity was not detected in any of the groundwater samples obtained from the onsite monitoring wells that were drilled in 2008, indicating no tritium infiltration to the natural geological strata.The tritium activity was the only activity detected in the onsite groundwater samples. Lower limits of detection were met and sample analysis results were below the applicable reporting levels.Subsurface Water Due to Industry Operating Experience, the Wolf Creek Generating Station started collecting and analyzing subsurface water during 2010. Subsurface water monitoring is a portion of the Groundwater Protection Program and is implemented via procedure Al 07-007, Onsite Groundwater Protection Program Monitoring. | |||
The definitions for subsurface water include: 1. Water that is encountered below grade while excavating, trenching, or drilling outside of the Radiologically Controlled Area and within the area displayed in Figure 2 (of Al 07-007). This excludes recent rainfall build-up in open excavation trenches.2. Water that is encountered below grade or water that needs to be removed that is outside of a building, outside of the Radiologically Controlled Area and within the area displayed in Figure 2 (of Al 07-007). Examples may include electrical vaults, piping vaults, valve pits, manholes, concrete pits, etc. Excludes removing water from powerblock sumps, sanitary sewers, spill containment berms or from within buildings. | |||
The collection of subsurface water samples was coordinated by the WCGS Environmental Management group and the samples were analyzed by the WCGS Chemistry Laboratory. | |||
The subsurface water samples were analyzed for tritium. The following table identifies the sample dates, sample locations, and the analysis results. | |||
38 of 57 Date Location Tritium (pCi/L) Notes 3/16/11 Essential Service Water (ESW) Vault, piping, 3,739 No Gamma West of Control Building Emitters Detected 4/30/11 Cable Pull Manhole 120, Between Turbine Less Than No Gamma Building and Shop Building, north end. Minimum Emitters Detectable Detected Activity 6/23/11 XMA01A, XMA01B, XMA01C & XMA02 <1,931 Transformer Discharge Vault 6/23/11 XMA01D Transformer Discharge Vault <1,913 6/23/11 XMR01 Transformer Discharge Vault 2,860 6/23/11 XPB03 & XPB04 Transformer Discharge Vault <1,936 6/23/11 XNB01 & XNB02 Transformer Discharge Vault <1,913 As expected, tritium activity was detected in two of the subsurface water samples. The sample from the ESW vault was also analyzed for gamma activity and gamma emitters were not detected. | |||
Again, the detected tritium activity is likely due to the Plant's reuse of tritiated lake water. Lake water is used for plant cooling, which includes essential service water, and in the Fire Protection System. The measured tritium levels from subsurface water monitoring are lower than the tritium levels routinely detected in surface water collected from Coffey County Lake (2011 range was 9,847 to 15,523 pCi/L).Conclusion Based upon the results of the water samples that were analyzed in association with the Onsite Groundwater Protection Program, no potential leaks of radioactivity from systems, structures, or components were identified. | |||

SUMMARY
This Annual Radioactive Effluent Release Report (Report # 35) documents the quantities of liquid and gaseous effluents and solid waste released by Wolf Creek Generating Station (WCGS) from January 1, 2011 through December 31, 2011. The format and content of this report are in accordance with Regulatory Guide 1.21, Revision 1, "Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants." Sections 1, 11, III, and IV of this report provide information required by NRC Regulatory Guide 1.21 and Section 7.2 of AP 07B-003,"Offsite Dose Calculation Manual" (ODCM).Section I --- Section I contains, in detail, the quantities of radioactive liquid and gaseous effluents and cumulative dose summaries for 2011, tabulated for each quarter and for yearly totals.Specific ODCM effluent limits and dose limits are also listed in Section I, along with the percentage of the effluent limits actually released and the percentages of the dose limit actually received.
No effluent or dose limits were exceeded during 2011.An elevated release pathway does not exist at WCGS. All airborne releases are considered to be ground level releases.
The gaseous pathway dose determination is met by the WCGS ODCM methodology of assigning all gaseous pathways to a hypothetical individual residing at the highest annual X/Q and D/Q location, as specified in the ODCM. This results in a conservative estimate of dose to a member of the public, rather than determining each pathway dose for each release condition.
A conservative error of thirty percent has been estimated in the effluent data.As stated above, no ODCM dose limits were exceeded in 2011.Section II --- Section II includes supplemental information on continuous and batch releases, calculated doses, and solid waste disposal.
There were 49 gaseous batch releases in 2011 versus 42 in 2010. There were 59 liquid batch releases in 2011 versus 42 in 2010. WCGS released 0.005 curies in liquid releases during 2011 versus 0.011 curies in 2010, excluding gas and tritium. Continuous release pathways remained the same as previous years and all continuous releases were monitored.
The report contains information on the following Condition Reports (CR): CR-42403 -ODCM surveillance was late due to monthly composites being completed after the late date.The report contains information on Carbon-14 evaluation.
The report contains information on Nickel-63 study.Section III --- Section III documents WCGS meteorological data for wind speed, wind direction, and atmospheric stability.
Section IV --- Section IV documents unplanned and abnormal releases, changes to radwaste treatment systems, land use census, monitoring instruments, radwaste shipments, and storage tank quantities.
There were no unplanned, unmonitored releases in 2011.Changes to the land use census are noted. No changes or events occurred with monitoring instruments, radwaste shipments, and storage units.

Batch Releases A batch release is the discontinuous release of gaseous or liquid effluents, which takes place over a finite period of time, usually hours or days.There were 49 gaseous batch releases during the reporting period. The longest gaseous batch release lasted 9,108 minutes, while the shortest lasted 56 minutes. The average release lasted 587 minutes with a total gaseous batch release time of 28,775 minutes.There were 59 liquid batch releases during the reporting period. The longest liquid batch release lasted 272 minutes, while the shortest lasted 55 minutes. The average release lasted 131 minutes with a total liquid batch release time of 7,741 minutes.6. Continuous Releases A continuous release is a release of gaseous or liquid effluent, which is essentially uninterrupted for extended periods during normal operation of the facility.
Four liquid release pathways were designated as continuous releases during this reporting period: Steam Generator Blowdown, Turbine Building Sump, Waste Water Treatment, and Lime Sludge Pond. Two gas release pathways were designated as continuous releases:
Unit Vent and Radwaste Building Vent.7. Doses to a Member of the Public from Activities Inside the Site Boundary Four activities by members of the public were considered in this evaluation:
personnel making deliveries to the plant, workers at the William Allen White Building located outside of the protected area boundary, the use of the access road south of the Radwaste Building, and public use of the cooling lake during times when fishing was allowed. The dose calculated for the maximum exposed individual for these four activities was as follows: Plant Deliveries 3.86E-01 mRem William Allen White Building Workers 8.36E-03 mRem Access Road Users 3.96E-03 mRem Lake Use 4.96E-02 mRem The plant delivery calculations were based on deliveries 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> per week for 50 weeks per year. The William Allen White Building occupancy was based on normal working hours of 2000 per year. The usage factor for the access road south of the Radwaste Building was 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> per year. The dose to fishermen on the lake was based upon 3,504 hours0.00583 days <br />0.14 hours <br />8.333333e-4 weeks <br />1.91772e-4 months <br /> (12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> a day for 292 days, based on the number of days that the lake was open to fisherman).
Pathways used in the calculation were gaseous inhalation, submersion, and ground plane. All calculations were performed in accordance with the methodology and parameters in the ODCM.8. Additional Information CR- 42403 -The July monthly liquid effluent composites were completed after the late date of August 7, 2011. Composites are due the 1st of each month, with a 25% grace period. All the necessary samples were available to make the composites, but there were no qualified technicians on site to perform the required calculations and preparations once it was recognized that composites were not done. Composites were completed satisfactorily on the next working day that qualified technicians were available, which was 21 of 57 August 8, 2011. This resulted in an Offsite Dose Calculation Manual surveillance being completed late. New surveillances were created and included in the site surveillance program to try to alleviate further instances of this happening.
Carbon-14 (CR 36059)Regulation 10CFR50.36a requires nuclear power plants to report quantities of principal radionuclides in the annual radioactive effluent release report. In the early 1980s, the NRC decided that C-14 radionuclide would not be required to be reported because it would not make a significant contribution to dose. Since this time, technology has advanced both for effluent isotopic reduction and isotope detection and estimation.
It is more likely the C-14 meets the definition of a principal radionuclide in accordance with the newly published Regulatory Guide 1.21 Revision 2 (June 2009).The NRC allows the reporting of this isotope based on estimation methods. EPRI TR 1021106 developed an estimation method based on peer-reviewed research that incorporates parameters of Wolf Creek's reactor design to estimate the gross amount of C-14 produced annually.
This value is fed into additional calculations, based on Regulatory Guide 1.109, Calculation of Annual Doses to Man From Routine Releases of Reactor Effluents For the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I, to provide an estimation of annual dose. Based on the 2010 theoretical calculations and assuming the maximum percentage of inorganic C-14 compounds (30%), Wolf Creek has estimated the annual release of C-14 to be 10.7 curies and to contribute maximum dose values of 1.30 mrem/yr child bone dose and 0.259 mrem/yr child total body. This is well below the 1OCFR50, Appendix I, ALARA design objective of 15 mrem/yr. Additionally, this value is on par with the dose expected from naturally occurring radiocarbon.
Nickel-63 Study Regulation 1OCFR50.36a requires nuclear power plants to report quantities of principal radionuclides in the annual radioactive effluent release report. To meet this requirement, periodic monitoring of potential isotopes in the waste streams is performed and any findings evaluated.
Wolf Creek is not currently required by the ODCM to monitor for Ni-63 in the liquid effluents.
However, to determine if Ni-63 is present in the liquid effluents, all 4 th quarter liquid composites were analyzed for the nuclide. The Batch composite resulted in positive values of Ni-63. The remaining composites, Steam Generator Blowdown to the Lake, Waste Water Treatment, Turbine Building Sump and Lime Sludge Pond, were all none detected.Using the Ni-63 detected in the quarterly Batch composite, the amount released for the year was conservatively estimated using the total liquid batch volume released and the total release duration for the year. Based on these estimates, Wolf Creek would release approximately 4.5E-04 mRem/year adult bone dose, which was the highest organ affected.
Compared to 2.2E-01 mRem/year, which is the dose due to the highest organ for the year (adult Gi-LLI), the estimated Ni-63 bone dose is a minimal contributor.
This estimation is well below the 1OCFR50, Appendix I limit of 10 mRem/year to any organ.

35 of 57 8. NEI Groundwater Protection Industry Initiative ONSITE GROUNDWATER PROTECTION PROGRAM MONITORING Objective The objective of onsite groundwater protection program monitoring is to detect potential leaks of radioactivity from systems, structures, or components to the groundwater.
At the Wolf Creek Generating Station, some background tritium influences from lake water are normal and expected.Basis The onsite groundwater protection program monitoring sample results are being reported in the Radioactive Effluent Release Report per guidance received in association with the Nuclear Energy Institute (NEI) Groundwater Protection Industry Initiative.
The following information is also being reported in association with the NEI 07-07 Groundwater Protection Industry Initiative:
- 1. Describe any onsite licensed radioactive materials releases or spills that were voluntarily communicated to State/Local officials during the calendar year. -None 2. Describe any onsite groundwater sample results that exceeded the reporting thresholds that were voluntarily communicated to State/Local officials during the calendar year. -None Onsite Groundwater Protection Program Monitoring Description In March of 2006, Wolf Creek Generating Station (WCGS) established an onsite groundwater protection monitoring program. During 2008, thirteen monitoring wells were added to the onsite groundwater protection monitoring program. The onsite groundwater protection program monitoring is implemented via procedure Al 07-007, Onsite Groundwater Protection Program Monitoring.
The onsite groundwater samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc., Midwest Laboratory.
Onsite groundwater samples were collected quarterly and were analyzed by gamma isotopic analysis, radiochemical analysis for 1-131 and tritium analysis.
The vendor lab participated in an interlaboratory comparison program. The following tables describe the sample locations, the lower limits of detection and the reporting levels for radioactivity detected.

This has been attributed to the Plant's reuse of tritiated lake water, and consistent with gaseous tritium deposition during normal operation.
Lake water is used for plant cooling, which includes essential service water, and in the Fire Protection System. The location with the highest level of tritium detected was WEST ESW-W (2,097 +/- 154 pCi/L), which likely resulted from direct lake water inputs from an essential service water pipe leak. The leak has since been repaired.
The measured tritium levels are significantly lower than the tritium levels routinely detected in surface water collected from Coffey County Lake (2011 range was 9,847 to 15,523 pCi/L). Tritium activity was not detected in any of the groundwater samples obtained from the onsite monitoring wells that were drilled in 2008, indicating no tritium infiltration to the natural geological strata.The tritium activity was the only activity detected in the onsite groundwater samples. Lower limits of detection were met and sample analysis results were below the applicable reporting levels.Subsurface Water Due to Industry Operating Experience, the Wolf Creek Generating Station started collecting and analyzing subsurface water during 2010. Subsurface water monitoring is a portion of the Groundwater Protection Program and is implemented via procedure Al 07-007, Onsite Groundwater Protection Program Monitoring.
The definitions for subsurface water include: 1. Water that is encountered below grade while excavating, trenching, or drilling outside of the Radiologically Controlled Area and within the area displayed in Figure 2 (of Al 07-007). This excludes recent rainfall build-up in open excavation trenches.2. Water that is encountered below grade or water that needs to be removed that is outside of a building, outside of the Radiologically Controlled Area and within the area displayed in Figure 2 (of Al 07-007). Examples may include electrical vaults, piping vaults, valve pits, manholes, concrete pits, etc. Excludes removing water from powerblock sumps, sanitary sewers, spill containment berms or from within buildings.
The collection of subsurface water samples was coordinated by the WCGS Environmental Management group and the samples were analyzed by the WCGS Chemistry Laboratory.
The subsurface water samples were analyzed for tritium. The following table identifies the sample dates, sample locations, and the analysis results.
38 of 57 Date Location Tritium (pCi/L) Notes 3/16/11 Essential Service Water (ESW) Vault, piping, 3,739 No Gamma West of Control Building Emitters Detected 4/30/11 Cable Pull Manhole 120, Between Turbine Less Than No Gamma Building and Shop Building, north end. Minimum Emitters Detectable Detected Activity 6/23/11 XMA01A, XMA01B, XMA01C & XMA02 <1,931 Transformer Discharge Vault 6/23/11 XMA01D Transformer Discharge Vault <1,913 6/23/11 XMR01 Transformer Discharge Vault 2,860 6/23/11 XPB03 & XPB04 Transformer Discharge Vault <1,936 6/23/11 XNB01 & XNB02 Transformer Discharge Vault <1,913 As expected, tritium activity was detected in two of the subsurface water samples. The sample from the ESW vault was also analyzed for gamma activity and gamma emitters were not detected.
Again, the detected tritium activity is likely due to the Plant's reuse of tritiated lake water. Lake water is used for plant cooling, which includes essential service water, and in the Fire Protection System. The measured tritium levels from subsurface water monitoring are lower than the tritium levels routinely detected in surface water collected from Coffey County Lake (2011 range was 9,847 to 15,523 pCi/L).Conclusion Based upon the results of the water samples that were analyzed in association with the Onsite Groundwater Protection Program, no potential leaks of radioactivity from systems, structures, or components were identified.
