The gamma air dose and beta air dose were calculated at the nearest Site Boundary location with the highest value of X/Q, as described in the ODCM. The maximum organ dose from gaseous effluents was calculated for the ingestion, inhalation, and ground plane pathways at the location of the nearest resident with the highest value of X/Q, as described in the ODCM. The organ dose from 14 C was calculated as described in EPRI Technical Report 1021106 3 and is documented in HPCI 12-02 4* 5.2 Table A-5, EPA 40 CFR 190 Individual in the U nrestricted Area The dose asses s ments reported in Tab le A-5 are the doses to the Member of the Public from activities within the Site Boundary p l us the doses at the location of the Nearest Re s id e nce. A large portion of the residual land of the Callaway Site is managed by the State of Mi s souri Conservation D e partment as the Reform Wildlife Management Area. Pursuant to th e guidance provided in Regulatory Guide 1.21, rev.2, the dose reported in Table A-5 is the sum of the do s e from gaseous effluents (at the Nearest Resident location and within the Site Boundary), plus the dose contribution due to activities within the Site boundary from direct radiation sources, including dose from outdoor water storage tanks and direct dose due to 16 N from op e ration of the unit, plus the organ dose from inhalation of 14 C (at the Nearest Resident location and within the Site Boundary).

: 1. Introduction This Annual Radioactive Effluent Release Report (ARERR) is submitted by Union Electric Co., dba Ameren Missouri, in accordance with the requirements of 10 CFR 50.36a and Callaway Energy Center Technical Specification 5.6.3. This report is for the period January 1, 2011 to December 31, 2011.
Callaway Energy Center 2011 Annual Radiological Effluent Release Report 6.4 Annual Land Use Census Changes The evaluation of the 2011 Land Use Census is documented in HPCI12-01.
The dose to the Member of the Public from all liquid and gaseous effluents discharged during the reporting period were small fractions of the NRC and EPA regulatory limits and the Radiological Effluent Control limits in the Offsite Dose Calculation Manual.
5 There were no changes in the locations for dose calculation.
To maximize consistency, aid in the review by Members of the Public, and to allow easier industry- wide comparison of the data, this report is presented in the format recommended by Regulatory Guide 1.21, revision 2, insofar as is practicable. Callaway is committed to revision
Changes in sample locations identified in the Land Use Census are described in the Annual Radiological Environmental Operating Report. 6.5 Effluent Monitoring System Inoperability Specifications covering the Limiting Conditions of Operations (LCO) for effluent monitoring instrumentation are provided in Radiological Effluent Control (REC) 16.11.1. 3 and 16.11.2.4.
 
The ACTION statement implements provisions that when taken as specified complete requirements to demonstrate functionality.
Callaway Energy Center 2011 Annual Radiological Effluent Release Report 1 of Regulatory Guide 1.21, and some of the information is not readily available in the format recommended by revision 2.
When the required ACTION is not met, the equipment is removed from service or declared non-functional.
: 2. Gaseous Effluents The quantity of radioactive material released in gaseous effluents during the reporting period is summarized in Table A-1. The quarterly and annual sums of all radionuclides discharged in gaseous effluents are reported in Tables A-lA and A-lB. All gaseous effluent releases are considered to be ground level.
This report provides an explanation for periods of time when in operability occurred.
14 The quantity of C released in gaseous effluents was calculated as described in EPRI Technical 1                                     2 Report 1021106 and is documented in HPCI12-02 .
REC 16.11.2.4, Table 16.11-5 requires the containment purge system particulate sampler functional during core alterations and movement of irradiated fuel within the containment.
: 3. Liquid Effluents The quantity of radioactive material released in liquid effluents during the reporting period is summarized in Table A-2. The quarterly and annual sums of all radionuclides discharged in liquid effluents are reported in Table A-2A. All liquid effluents were discharged in batch mode; there were no continuous liquid discharges for the reporting period. Dilution by the Missouri River, in the form of the near- field dilution factor, is utilized in the ODCM dose calculation methodology.
On October 23, 2011, with fuel movement in progress, a routine scheduled surveillance of the containment shutdown purge found the flow rate to be 7746 cfm. The allowed flow rate is 20,000 +/- 10%. This represented an increase in the ratio of the isokinetic probe inlet velocity to the duct velocity by a factor of 2.6. Per Table C1 of ANSI Nl3.1-1969, "Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities", this would have resulted in a loss of >50% of the large particles, therefore the sampling was not isokinetic and the sample may not have been representative of the process stream 6* The low flow condition was discovered at approximately 04:30 and full flow was restored at approximately 09:44. Containment particulate effluent is filtered through HEPA filters downstream of the sample point and is discharged through the Unit Vent. All particulate effluent discharged through the Unit Vent is sampled by the Unit Vent particulate sampler prior to discharge.
4* Solid Waste Storage and Shipments The volume and activity of solid waste shipped for disposal is provided in Table A-3. Table A*3 is presented in the format of rev. 1 to Regulatory Guide 1.21 because the data is not readily available in the format recommended by rev. 2 to Regulatory Guide 1.21.
The Unit Vent particulate sampler was functional during the period of low containment purge flow rate and the particulate activity discharged via the Unit Vent was normal. All particulate activity discharged through the Unit Vent is accounted in the gaseous effluent tables of this report. The loss of isokinetic sampling for the containment purge exhaust had no effect on the accuracy of the particulate activity shown in the gaseous effluent tables of this report. 6.6 Offsite Dose Calculation Manual Changes There were no changes to the Offsite Dose Calculation Manual during the reporting period. 6. 7 Process Control Program Changes There were no changes to APA-ZZ-01011, "Process Control Program" during the reporting period. 5 HPCI12-01, "Evaluation of the 2011 Annua l Land Use Census" 6 CARs 201108757, 201108954 Action 2.2, & 201110696.
: s. Dose Assessments The annual evaluation of dose to the Member of the Public is calculated in accordance with the methodology and parameters in the ODCM and is reported in Tables A-4 and A-5.

Callaway Energy Center 2011 Annual Radiological Effluent Release Report 6.4 Annual Land Use Census Changes 5
The evaluation of the 2011 Land Use Census is documented in HPCI12-01. There were no changes in the locations for dose calculation. Changes in sample locations identified in the Land Use Census are described in the Annual Radiological Environmental Operating Report.
6.5 Effluent Monitoring System Inoperability Specifications covering the Limiting Conditions of Operations (LCO) for effluent monitoring instrumentation are provided in Radiological Effluent Control (REC) 16.11.1. 3 and 16.11.2.4.
The ACTION statement implements provisions that when taken as specified complete requirements to demonstrate functionality. When the required ACTION is not met, the equipment is removed from service or declared non- functional. This report provides an explanation for periods of time when in operability occurred.
REC 16.11.2.4, Table 16.11-5 requires the containment purge system particulate sampler functional during core alterations and movement of irradiated fuel within the containment. On October 23, 2011, with fuel movement in progress, a routine scheduled surveillance of the containment shutdown purge found the flow rate to be 7746 cfm. The allowed flow rate is 20,000 +/- 10%. This represented an increase in the ratio of the isokinetic probe inlet velocity to the duct velocity by a factor of 2.6. Per Table C1 of ANSI Nl3.1-1969, "Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities", this would have resulted in a loss of >50%
of the large particles, therefore the sampling was not isokinetic and the sample may not have 6
been representative of the process stream
* The low flow condition was discovered at approximately 04:30 and full flow was restored at approximately 09:44. Containment particulate effluent is filtered through HEPA filters downstream of the sample point and is discharged through the Unit Vent. All particulate effluent discharged through the Unit Vent is sampled by the Unit Vent particulate sampler prior to discharge. The Unit Vent particulate sampler was functional during the period of low containment purge flow rate and the particulate activity discharged via the Unit Vent was normal. All particulate activity discharged through the Unit Vent is accounted in the gaseous effluent tables of this report. The loss of isokinetic sampling for the containment purge exhaust had no effect on the accuracy of the particulate activity shown in the gaseous effluent tables of this report.
6.6 Offsite Dose Calculation Manual Changes There were no changes to the Offsite Dose Calculation Manual during the reporting period.
: 6. 7 Process Control Program Changes There were no changes to APA-ZZ-01011, "Process Control Program" during the reporting period.

1. Introduction This Annual Radioactive Effluent Release Report (ARERR) is submitted by Union Electric Co., dba Ameren Missouri, in accordance with the requirements of 10 CFR 50.36a and Callaway Energy Center Technical Specification 5.6.3. This report is for the period January 1, 2011 to December 31, 2011.

The dose to the Member of the Public from all liquid and gaseous effluents discharged during the reporting period were small fractions of the NRC and EPA regulatory limits and the Radiological Effluent Control limits in the Offsite Dose Calculation Manual.

To maximize consistency, aid in the review by Members of the Public, and to allow easier industry- wide comparison of the data, this report is presented in the format recommended by Regulatory Guide 1.21, revision 2, insofar as is practicable. Callaway is committed to revision

Callaway Energy Center 2011 Annual Radiological Effluent Release Report 1 of Regulatory Guide 1.21, and some of the information is not readily available in the format recommended by revision 2.

2. Gaseous Effluents The quantity of radioactive material released in gaseous effluents during the reporting period is summarized in Table A-1. The quarterly and annual sums of all radionuclides discharged in gaseous effluents are reported in Tables A-lA and A-lB. All gaseous effluent releases are considered to be ground level.

14 The quantity of C released in gaseous effluents was calculated as described in EPRI Technical 1 2 Report 1021106 and is documented in HPCI12-02 .

3. Liquid Effluents The quantity of radioactive material released in liquid effluents during the reporting period is summarized in Table A-2. The quarterly and annual sums of all radionuclides discharged in liquid effluents are reported in Table A-2A. All liquid effluents were discharged in batch mode; there were no continuous liquid discharges for the reporting period. Dilution by the Missouri River, in the form of the near- field dilution factor, is utilized in the ODCM dose calculation methodology.

4* Solid Waste Storage and Shipments The volume and activity of solid waste shipped for disposal is provided in Table A-3. Table A*3 is presented in the format of rev. 1 to Regulatory Guide 1.21 because the data is not readily available in the format recommended by rev. 2 to Regulatory Guide 1.21.

s. Dose Assessments The annual evaluation of dose to the Member of the Public is calculated in accordance with the methodology and parameters in the ODCM and is reported in Tables A-4 and A-5.

2 14 HPCI12-02, "Dose to the Member of the Public from the Release of C Gaseous Effluents for 2011".

Callaway Energy Center 2011 Annual Radiological Effluent Release Report 5.1 Table A-4, Dose Assessments, 10 CFR 50, Appendix I The dose assessments reported in Table A-4 were calculated using the methodology and parameters in the ODCM and demonstrate compliance with 10 CFR 50, Appendix I. The gamma air dose and beta air dose were calculated at the nearest Site Boundary location with the highest value of X/Q, as described in the ODCM. The maximum organ dose from gaseous effluents was calculated for the ingestion, inhalation, and ground plane pathways at the location of the nearest resident with the highest value of X/Q, as described in the ODCM. The organ dose from 14 3 C was calculated as described in EPRI Technical Report 1021106 and is documented in HPCI 4

12-02

  • 5.2 Table A-5, EPA 40 CFR 190 Individual in the Unrestricted Area The dose assessments reported in Table A-5 are the doses to the Member of the Public from activities within the Site Boundary plus the doses at the location of the Nearest Residence. A large portion of the residual land of the Callaway Site is managed by the State of Missouri Conservation Department as the Reform Wildlife Management Area. Pursuant to the guidance provided in Regulatory Guide 1.21, rev.2, the dose reported in Table A-5 is the sum of the dose from gaseous effluents (at the Nearest Resident location and within the Site Boundary), plus the dose contribution due to activities within the Site boundary from direct radiation sources, 16 including dose from outdoor water storage tanks and direct dose due to N from operation of 14 the unit, plus the organ dose from inhalation of C (at the Nearest Resident location and within the Site Boundary). The dose assessments in Table A-5 demonstrate compliance with 10 CFR 20.1301(e) and 40 CFR 190.
6. Supplemental Information 6.1 Abnormal Releases or Abnormal Discharges There were no abnormal releases or abnormal discharges during the reporting period.

6.2 Non- routine Planned Discharges There were no non- routine planned discharges during the reporting period.

6.3 Radioactive Waste Treatment System Changes There were no major changes to the liquid or gaseous radwaste treatment system during the reporting period.

Callaway Energy Center 2011 Annual Radiological Effluent Release Report 6.4 Annual Land Use Census Changes 5

The evaluation of the 2011 Land Use Census is documented in HPCI12-01. There were no changes in the locations for dose calculation. Changes in sample locations identified in the Land Use Census are described in the Annual Radiological Environmental Operating Report.

6.5 Effluent Monitoring System Inoperability Specifications covering the Limiting Conditions of Operations (LCO) for effluent monitoring instrumentation are provided in Radiological Effluent Control (REC) 16.11.1. 3 and 16.11.2.4.

The ACTION statement implements provisions that when taken as specified complete requirements to demonstrate functionality. When the required ACTION is not met, the equipment is removed from service or declared non- functional. This report provides an explanation for periods of time when in operability occurred.

REC 16.11.2.4, Table 16.11-5 requires the containment purge system particulate sampler functional during core alterations and movement of irradiated fuel within the containment. On October 23, 2011, with fuel movement in progress, a routine scheduled surveillance of the containment shutdown purge found the flow rate to be 7746 cfm. The allowed flow rate is 20,000 +/- 10%. This represented an increase in the ratio of the isokinetic probe inlet velocity to the duct velocity by a factor of 2.6. Per Table C1 of ANSI Nl3.1-1969, "Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities", this would have resulted in a loss of >50%

of the large particles, therefore the sampling was not isokinetic and the sample may not have 6

been representative of the process stream

  • The low flow condition was discovered at approximately 04:30 and full flow was restored at approximately 09:44. Containment particulate effluent is filtered through HEPA filters downstream of the sample point and is discharged through the Unit Vent. All particulate effluent discharged through the Unit Vent is sampled by the Unit Vent particulate sampler prior to discharge. The Unit Vent particulate sampler was functional during the period of low containment purge flow rate and the particulate activity discharged via the Unit Vent was normal. All particulate activity discharged through the Unit Vent is accounted in the gaseous effluent tables of this report. The loss of isokinetic sampling for the containment purge exhaust had no effect on the accuracy of the particulate activity shown in the gaseous effluent tables of this report.

6.6 Offsite Dose Calculation Manual Changes There were no changes to the Offsite Dose Calculation Manual during the reporting period.

6. 7 Process Control Program Changes There were no changes to APA-ZZ-01011, "Process Control Program" during the reporting period.
