Introdu c tion 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, 2012 to December 31, 2012. The doses 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 ofthe 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 Abstract The Annual Radioactive Effluent Release Report covers the operation of the Callaway Energy Center during the year 2012. The report includes a summary of the quantities of radioactive liquid and gaseous effluents and solid released from the unit. The report includes an annual summary of hourly meteorological data collected during the year and an assessment of radiation to the Member of the Public from liquid and gaseous effluents. t 0 Q.

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. The quantity of 14 C released in gaseou s effluents was calculated as described in EPRI Technical Report 1021106 1* 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 i s 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. 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/0, 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 D/0, as described in the ODCM. The organ dose does not include the dose from 14 C, which is listed separately. 1 Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents, Technical Report 1011106, Electric Power Research Institute, December, 2010. Callaway Energy Center 2012 Annual Radiological Effluent Release Report 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 and the organ dose from inhalation of 14 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. 6.4 Annual Land Use Census Changes There were no changes identified 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 lnoperability There were no effluent radiation monitors out of service for periods in excess of the Limiting Condition for Operation and associated Action statements.

6.6 Offsite

Dose Calculation Manual Changes The Offsite Dose Calculation Manual (ODCM) was revised during the reporting period. Revision 19 was issued on August 7, 2012. A complete copy of the revised ODCM is attached. Revision 19 was a general revision with major formatting changes. For clarity and as an aid to the reviewer, the marks in the margins show only those areas of substantive change. Appendix B to the ODCM provides a description of the changes. 6. 7 Process Control Program Changes APA-ZZ-01011, "Process Control Program" was revised tw i ce during the reporting period. Revision 11, issued on September 6, 2012 , aligned the PCP change and approval process with Callaway Energy Center 2012 Annual Radiological Effluent Release Report APA-ZZ-00101, "Processing Procedure s, manuals , and Desktop Instructions" and FSAR-SP Specification 16.25, "Process Control Program (PCP). Revision 12, issued on October 8, 2012, was a minor change correcting the title of APA-ZZ-00101 as referenced in the procedure. Neither change resulted in a change in the formulas, sampling, analyses, tests or determinations relative to the processing and packaging of solid radioactive waste. Documentation relative to these changes is retained in the Callaway Energy Center records. 6.8 Corrections to Previous Reports There are no corrections to previous reports. 6.9 Other Information Related to Radioactive Effluents Meteorological Joint Frequency Tables for the monitoring period are attached as Appendix B.

Purpose and Scope APA-ZZ-01 003 Rev. 019 The Offsite Dose Calculation Manual (ODCM) describes the methodology and parameters used in the calculation of off-site doses resulting from radioactive gaseous and liquid effluents, in the calculation of gaseous and liquid effluent monitoring Alarm/Trip Setpoints, and in the conduct of the Radiological Environmental Monitoring Program. The ODCM also contains the Radioactive Effluent Controls and Radiological Environmental Monitoring Program required by TIS 5.5.4 and FSAR-SP Chapter 16.11.4, and descriptions of the information that should be included in the Annual Radiological Environmental Operating and Annual Effluent Release Reports required by TIS 5.6.2 and TIS 5.6.3 Compliance with the Radiological Effluent Controls limits demonstrates compliance with the limits of 10 CFR 20.1301.1 *2*3 The ODCM consists of two parts: FSAR-SP Chapter 16.11 which contains the Radiological Effluent Controls (RECs), and APA-ZZ-01003, which contains the methodology and parameters used to implement the RECs. 2. Liquid Effluents

2.1. Liquid

Effluent Monitors Gross radioactivity monitors which provide for automatic termination of liquid effluent releases are present on the liquid effluent lines. Flow rate measurement devices are present on the liquid effluent lines and the discharge line (cooling tower blowdown). Setpoints, precautions, and limitations applicable to the operation of the Callaway Plant liquid effluent monitors are provided in the appropriate Plant Procedures. Setpoint values are calculated to assure that alarm and trip actions occur prior to exceeding ten times the Effluent Concentration Values (ECV) limits in 10 CFR Part 20 at the release point to the Unrestricted Area. The calculated alarm and trip action setpoints for the liquid effluent line monitors and flow measuring devices must satisfy the following equation: Eq.l Where: 1 Statements of Consideration, Federal Register, Vol. 56, No. 98, Tuesday, May 21, 1991, Subpart D, page 2337 4 2 10 CFR 50.36 a (b) 3 Letter, F. J. Congel to J. F. Schmidt, dated April23, 1991 Page 5 of72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Cis the liquid effluent concentration value (ECV) implementing REC 16.11.1.1 for the site in !JCilml; c is the setpoint, in (IJCilml), of the radioactivity monitor measuring the radioactivity concentration in the effluent line prior to dilution and subsequent release. The setpoint, which is inversely related to the volumetric flow of the effluent line and directly related to the volumetric flow of the dilution stream plus the effluent steam, represents a value, which, if exceeded, would result in concentrations exceeding ten times the values of 10 CFR Part 20 Appendix B, Table 2, Column 2, in the Unrestricted Area; f is the undiluted waste flow rate as measured at the radiation monitor location, in volume per unit time, but in the same units as F, below; and F is the dilution water flow rate setpoint as measured prior to the release point, in volume per unit time. If F is large compared to f, then F + f = F. 4 If no dilution is provided then c C. The radioactive liquid waste stream is diluted by the plant discharge line prior to entry into the Missouri River. Normally, the dilution flow is obtained from the cooling tower blowdown, but should this become unavailable, the plant water treatment facility supplies the necessary dilution flow via a bypass line. The limiting concentration which corresponds to the liquid radwaste effluent monitor setpoint is to be calculated using methodology from the expression above. Thus, the expression for determining the setpoint of the liquid radwaste effluent line monitor becomes: c:::; C{F +f) (11Ci I ml) f Eq.2 The alarm/trip setpoint calculations are based on the minimum dilution flow rate (corresponding to the dilution flow rate setpoint), the maximum effluent stream flow rate, and the actual isotopic analysis. Due to the possibility of a simultaneous release from more than one release pathway, a portion of the total site release limit is allocated to each pathway. The determination and usage of the allocation factor is discussed in Section 2.2. In the event the alarm/trip setpoint is reached, an evaluation will be performed using actual dilution and effluent flow values and actual isotopic analysis to ensure that REC 16.11.1.1 limits were not exceeded.

2.1.1. Continuous

Liquid Effluent Monitors The radiation detection monitor associated with continuous liquid effluent releases is: 5*6 4 NUREG-0133, pages AA-1 thru AA-3 5 FSAR-SP, Section 11.5.2.2.3.1 6 FSAR-SP, Section 11.5.2.2.3.4 Page 6 of72 INFORMATION USE August 2012 Description APA-ZZ-01 003 Rev. 019 Monitor I. D. SM-RE-52 Steam Generator Slowdown Discharge Monitor The Steam Generator Slowdown discharge is not considered to be radioactive unless radioactivity has been detected by the associated effluent radiation monitor or by laboratory analysis. The sampling frequency, minimum analysis frequency, and type of analysis performed are Per FSAR-SP Table 16.11-1. 2.1.2. Radioactive Liquid Batch Release Effluent Monitors The radiation monitor associated with the liquid effluent batch release system is: 7 Description Monitor I.D. HS-RE-18 Liquid Radwaste Discharge Monitor This effluent stream is normally considered to be radioactive. The sampling frequency, minimum analysis frequency, and the type of analysis performed are per FSAR-SP Table 16.11-1. 2.2. Calculation of Liquid Effluent Monitor Setpoints The dependence of the setpoint, c, on the radionuclide distribution, yields, calibration, and monitor parameters, requires that several variables be considered in setpoint calculations. 8 2.2.1. Calculation of the ECV Sum The isotopic concentration of the release(s) being considered must be determined. This is obtained from the analyses required per FSAR-SP Table 16.11-1, and is used to calculate an ECV sum (ECVSUM): ECVSUM =(L( C;) / (EC\1; )} Eq.3 Where: C 9 is the concentration of each measured gamma emitting nuclide observed by gamma-ray spectroscopy of the waste sample; Ca is the concentration of 237 Np, 238 Pu, 2391240 Pu, 241 Pu, 241 Am, 242 Cm, & 2431244 Cm, in the quarterly composite sample based on previous composite sample analyses; 7 FSAR-SP, Section 11.5.2.2.3.2 8 NUREG-0133, pages AA-1 thru AA-3 Page 7 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Cs is the measured concentrations of 89 Sr and 90 Sr as determined by analysis of the quarterly composite sample based on previous composite sample analyses; Ct is the measured concentration of 3 H in the waste sample; and Ct is the measured concentration of 55 Fe & 63 Ni as determined by analysis of the quarterly composite sample based on previous composite sample analyses. ECV 9 , ECV 5 , ECVa. ECVt. and ECVt are ten times the limiting concentrations of the appropriate radionuclides from 10 CFR 20, Appendix B, Table 2, Column 2. For dissolved or entrained noble gases, the concentration shall be limited to 2x1 o-4 IJCi/ml total activity. For the case ECVSUM ::;1, the monitor tank effluent concentration meets the limits of REC 16.11.1.1 without dilution and the effluent may be released at any desired flow rate. If ECVSUM > 1 then dilution is required to ensure compliance with the concentration limits of REC 16.11.1.1. If simultaneous releases are occurring or are anticipated, an allocation fraction, N, must be applied so that available dilution flow may be apportioned among simultaneous discharge pathways. The value of N may be any value between 0 and 1 for a particular discharge point, provided that the sum of the allocation fractions for all discharge points must be ::;1. 2.2.2. Calculation of the Maximum Permissible Liquid Effluent Discharge Flow Rate The maximum permissible liquid effluent discharge flow rate is calculated by: Where: fmax s(F + JP)*SF *N.:,-{ECVSUM) Eq.4 fmax is the maximum permissible liquid effluent discharge flow rate, (in gallons/minute); fp is the expected undiluted liquid effluent flow rate, in gpm; N is the allocation fraction which apportions dilution flow among simultaneous discharge pathways (see discussion above); and SF is the safety factor; an administrative factor used to compensate for statistical fluctuations and errors of measurements. This factor also provides a margin of safety in the calculation of the maximum liquid effluent discharge flow rate (fmaJ The value of SF should be 1. F and ECVSUM are previously defined. The dilution water supply is furnished with a flow monitor which isolates the liquid effluent discharge if the dilution flow rate falls below its setpoint value. In the event that fmax is less than fp. then the value of fmax is substituted into the equation for fp. and a new fmax value is calculated. This substitution is performed for three iterations in order to calculate the correct value of fmax* Page 8 of72 INFORMATION USE August 2012

2.2.3. Calculation

of Liquid Effluent Monitor Setpoint APA-ZZ-01 003 Rev. 019 The liquid effluent monitors are Nai(TI) based systems and respond primarily to gamma radiation. Accordingly, their setpoint is based on the total concentration of gamma emitting nuclides in the effluent: c = o.9s *[bkg +[ricg)+SF ]] Eq.S Where: cis the monitor setpoint as previously defined, in !JCilml; bkg is the monitor background prior to discharge, in !JCi/ml, adjusted for monitor response; and 0.95 is a factor for conservatism to ensure the monitor trips prior to exceeding the limits of REC 16.11.1.1 Icg and SF are as previously defined. The monitor's background is controlled at an appropriate limit to ensure adequate sensitivity. Utilizing the methodology of ANSI N13.10-1974, the background must be maintained at a value of less than or equal to 9x10-6 1JCi/ml (relative to 137 Cs) in order to detect a change of 4x1 o-7 !JCi/ml of 137 Cs. 9 In the event that there is no detectable gamma activity in the effluent or if the value of { {L Cg }+SF} is less than the background of the monitor, then the monitor setpoint will be set at twice the current background of the monitor. As previously stated, the monitor's response is dependent on the gamma emitting radionuclide distribution of the effluent. Accordingly, a database conversion factor is calculated for each release based upon the results of the gamma spectrometric analysis of the effluent sample and the measured response of the monitor to National Institute of Standards and Technology (NIST) traceable calibration sources: Eq.6 DBCFc is the monitor data base conversion factor which converts count rate into concentration (!JCi/ml); CMR is the calculated response of the radiation monitor to the liquid effluent; 9 HPCI 96-005, "Calculation of Maximum Background Value for HB-RE-18" Page 9 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 ECF is the conversion factor for 137 Cs, which converts count rate into concentration (IJCi/ml). C is as previously defined. g The new value of the DBCFc is calculated and entered into the monitor data base prior to each discharge. A more complete discussion of the derivation and calculation of the CMR is given in HPCI 87-10. 2.3. Liquid Effluent Concentration Measurements Liquid batch releases are discharged as a discrete volume and each release is authorized based upon the sample analysis and the dilution flow rate existing in the discharge line at the time of release. To assure representative sampling, each liquid monitor tank is isolated and thoroughly mixed by recirculation of tank contents prior to sample collection. The methods for mixing, sampling, and analyzing each batch are outlined in applicable plant procedures. The allowable release rate limit is calculated for each batch based upon the pre-release analysis, dilution flow-rate, and other procedural conditions, prior to authorization for release. The liquid effluent discharge is monitored prior to entering the dilution discharge line and will automatically be terminated if the pre-selected alarm/trip setpoint is exceeded. Concentrations are determined primarily from the gamma isotopic and 3 H analyses of the liquid batch sample. For sgsr, gosr, ssFe, 63Ni, 237Np, 238Pu, 239t240Pu, 241Pu, 241Am, 242Cm, & 243/244Cm, the measured concentrations from the previous quarterly composite analyses are used until laboratory results become available. Composite samples are collected for each batch release and analyzed in accordance with FSAR-SP Table 16.11-1.The dose from liquids discharged as continuous releases is calculated by utilizing the last measured values of samples in accordance with FSAR-SP Table 16.11-1. 2.4. Dose due to Liquid Effluents 2.4.1. The Maximum Exposed Individual The cumulative dose determination considers the dose contributions from the maximum exposed individual's consumption of fish and potable water, as appropriate. Normally, the adult is considered to be the maximum exposed individual. 10 The Callaway Plant's liquid effluents are discharged to the Missouri River. As there are no potable water intakes within 10 miles of the discharge point, 11*12 this pathway does not require routine evaluation. Therefore, the dose contribution from fish consumption is expected to account for more than 95% of the total man-rem dose from discharges to the Missouri River. Dose from recreational activities is expected to contribute the additional 5%, which is considered to be negligible. 13 10 NUREG-0133, Section 4.3 11 Environmental Report, OLS, Table 2.1-19 12 FSAR-SP Section 11.2.3.3.4 13 FSAR-SP, Section 11.2.3.4.3 Page 10 of72 INFORMATION USE August 2012

2.4.2. Calculation

of Dose from Liquid Effluents m APA-ZZ-01 003 Rev. 019 The dose contributions for the total time period ILlt, are calculated at least once each 31 1=1 days and a cumulative summation of the total body and individual organ doses is maintained for each calendar quarter. Dose is calculated for all radionuclides identified in liquid effluents released to Unrestricted Areas using the following expression: 14 D, t llt, Cu F,] Eq.7 Where: D, is the cumulative dose commitment to the total body or any organ, *. from the liquid m effluents for the total period ,LLlt, in mrem. 1=1 LUI is the length of the r time period over which ci,l and Fl are averaged for all liquid releases, in hours. llt1 corresponds to the actual duration of the release(s). Ci,l is the average measured concentration of radionuclide, i, in undiluted liquid effluent during the time period llt1 from any liquid release, in (IJCilml).

• 89.77 Eq.S Where: Fmax is the maximum undiluted effluent flow rate during the release; F is the average dilution flow; and 89.77 is site specific applicable factor for the mixing effect of the discharge structure.

15*16*17 14 NUREG-0133, Section 4.3 15 NE0-54 16 UOTH 83-58 Page 11 of72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 The term C1,1 is the undiluted concentration of radioactive material in liquid waste at the common release point determined in accordance with REC 16.11.1.1, Table 16.11-1, "Radioactive Liquid Waste Sampling and Analysis Program". All dilution factors beyond the sample point(s) are included in the F1 term. As there are currently no potable water intakes within 10 river miles of the discharge point, the drinking water pathway is not included in dose estimates to the maximally exposed individual. Should future potable water intakes be constructed within 10 river miles downstream of the discharge point, then this manual will be revised to include this pathway in dose estimates. 18 2.4.3. Summary, Calculation of Dose Due to Liquid Effluents m The dose contribution for the total time period ILlt 1 is determined by calculation at least 1=1 once per 31 days and a cumulative summation of the total body and organ doses is maintained for each calendar quarter. The projected dose contribution from liquid effluents for which radionuclide concentrations are determined by periodic composite and grab sample analysis may be approximated by using the last measured value. Dose contributions are determined for all radionuclides identified in liquid effluents released to Unrestricted Areas. Nuclides which are not detected in the analyses are reported as "less than" the Minimum Detectable Activity (MDA) and are not reported as being present at the Lower Limit of Detection (LLD) for that nuclide. The "less than" values are not used in the dose calculations.

2.5. Liquid

Radwaste Treatment System The Liquid Radwaste Treatment System is described in FSAR-SP Chapter 11.2. The Operability of the Liquid Radwaste Treatment System ensures this system will be available for use when liquids require treatment prior to their release to the environment. Operability is demonstrated through compliance with REC 16.11.1.1. and 16.11.1.2. Projected doses due to liquid releases to Unrestricted Areas are determined each 31 days. The prior 31 day period is used to calculate compliance. This may be modified as appropriate to account for changes in radwaste treatment which may have a significant effect on the projected doses. 2.6. Dose Factors The dose conversion factors provided in Table 1 were derived from the appropriate dose conversion factors of Regulatory Guide 1.1 09, Table 2.2 and other sources as necessary. 19 3. Gaseous Effluents

3.1. Gaseous

Effluent Monitors 17 CAR 200700053-Attachments: Phase 1 final draft 18 FSAR-SP, Section 11.2.3.3.4 19 HPCI 04-06, rev. 1 Page 12 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Noble gas activity monitors are present on the containment building ventilation system, plant unit ventilation system, and radwaste building ventilation system. The alarm/trip (alarm & trip) setpoint for any gaseous effluent radiation monitor is determined based on the instantaneous noble gas total body and skin dose rate limits of REC 16.11.2.1, at the Site Boundary location with the highest annual average X/Q value. Each gaseous monitor channel is provided with a two level system which provides sequential alarms on increasing radioactivity levels. These setpoints are designated as alert setpoints and alarm/trip setpoints. 20 The radiation monitor alarm/trip setpoints for each release point are based on the radioactive noble gases in gaseous effluents. It is not considered practicable to apply instantaneous alarm/trip setpoints to integrating radiation monitors sensitive to radioiodines, radioactive materials in particulate form and radionuclides other than noble gases. The exception is RE-202. The only effluent released from the Laundry Decon Facility Dryer Exhaust is in the particulate form. Conservative assumptions may be necessary in establishing setpoints to account for system variables, such as the measurement system efficiency and detection capabilities during normal, anticipated, and unusual operating conditions, variability in release flow and principal radionuclides, and the time lag between alarm/trip action and the final isolation of the radioactive effluent. 21 FSAR-SP Table 16.11-6 provides the instrument surveillance requirements, such as calibration, source checks, functional tests, and channel checks. 3.1.1. Continuous Release Gaseous Effluent Monitors The radiation detection monitors associated with continuous gaseous effluent releases are: 22*23 Monitor I.D. GT-RE-21 GH-RE-10 GL-RE-202 Description Unit Vent Radwaste Building Vent Laundry Decon Facility Dryer Exhaust Monitor Each of the above continuously monitors gaseous radioactivity concentrations downstream of the last point of potential influent, and therefore measures effluents and not inplant concentrations. The unit vent monitor continuously monitors the effluent from the unit vent for gaseous radioactivity. The unit vent, via ventilation exhaust systems, continuously purges various tanks and sumps normally containing low-level radioactive aerated liquids that can potentially 2° FSAR-SP Section 11.5.2.1.2 21 NUREG-0133, section 5.1.1 22 FSAR-SP Section 11.5.2.3.3.1 23 FSAR-SP Section 11.5.2.3.3.2 Page 13 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 generate airborne activity. The exhaust systems which supply air to the unit vent are from the fuel building, auxiliary building, the access control area, the containment purge, and the condenser air discharge. The unit vent monitor provides alarm functions only, and does not terminate releases from the unit vent. The Radwaste Building ventilation effluent monitor continuously monitors for gaseous radioactivity in the effluent duct downstream of the exhaust filter and fans. The flow path provides ventilation exhaust for all parts of the building structure and components within the building and provides a discharge path for the waste gas decay tank release line. These components represent potential sources for the release of gaseous and air particulate and iodine activities in addition to the drainage sumps, tanks, and equipment purged by the waste processing system. This monitor will isolate the waste gas decay tank discharge line upon a high gaseous radioactivity alarm. The Laundry Decon Facility Dryer Exhaust Monitor continuously monitors the effluent of the dryer exhaust for particulate radioactivity during operation of the dryers. This effluent point is designed to release an insignificant quantity of radioactivity. The items to be placed in the dryers are typically washed before drying removing most of the radioactive material. The dryer effluent then passes through a HEPA filter before being sampled and released. The Laundry Decon Facility Dryer Exhaust Monitor will secure the dryers and exhaust fans and isolate the dryer effluent upon a high radioactivity alarm or for a monitor failure. The continuous Unit Vent and Radwaste Building Vent gaseous effluent monitor setpoints are established using the methodology described in Section 3.2. Since there are two continuous gaseous effluent release points, a fraction of the total dose rate limit (DRL) will be allocated to each release point. Neglecting the batch releases, the plant Unit Vent monitor has been allocated 0.7 DRL and the Radwaste Building Vent monitor has been allocated 0.3 DRL. These allocation factors may be changed as required to support plant operational needs, but shall not be allowed to exceed unity (i.e., 1.0). Therefore, a particular monitor reaching the setpoint would not necessarily mean the dose rate limit at the Site Boundary is being exceeded; the alarm only indicates that the specific release point is contributing a greater fraction of the dose rate limit than was allocated to the associated monitor, and will necessitate an evaluation of both systems. For a loss of all isokinetic sampling and/or all heat tracing for the Unit Vent or Radwaste Building Vent grab samplers, one hour is allowed to restore a sampler to service. If sampling cannot be restored within one hour, all batch releases and ventilation not required for the operation of the plant should be secured. The best available sampling should be maintained during this period and normal sampling returned to service as soon as possible. Page 14 of72 INFORMATION USE August 2012

3.1.2. Batch

Release Gaseous Effluent Monitors APA-ZZ-01 003 Rev. 019 The radiation monitors associated with batch release gaseous effluents are: 24*25*26 Monitor I.D. GT-RE-22, GT-RE-33 GH-RE-10 Description Containment Purge System Radwaste Building Vent The Containment Purge System continuously monitors the containment purge exhaust duct during purge operations for gaseous radioactivity. The primary purpose of these monitors is to isolate the containment purge system on high gaseous activity via the ESFAS. The sample points are located outside the containment between the containment isolation dampers and the containment purge filter adsorber unit. The Radwaste Building Vent monitor was previously described. A pre-release isotopic analysis is performed for each batch release to determine the identity and quantity of the principal radionuclides. The alarm/trip setpoint(s) is adjusted accordingly to ensure that the limits of REC 16.11.2.1 are not exceeded.

3.2. Gaseous

Effluent Monitor Setpoints The alarm/trip setpoint for the Unit Vent and Radwaste Building Vent gaseous effluent monitors is determined based on the more restrictive of the total body dose rate {Eq. 9) and skin dose rate {Eq. 11) as calculated for the Site Boundary. The alarm/ trip setpoint for the Laundry Decon Facility Exhaust Monitor is set to less than or equal to 2,000 cpm above equilibrium background. The maximum allowed background is 2,000 cpm as discussed in HPCI 99-05. 3.2.1. Total Body Dose Rate Setpoint Calculations To ensure that the limits of REC 16.11.2.1 are met, the alarm/trip setpoint based on the total body dose rate is calculated according to: Where: Stb ::; DtbRtbFsFa Eq.9 Stb is the alarm/trip setpoint based on the total body dose rate (J.I.Ci/cc); 24 FSAR-SP Section 11.5.2.3.3.2 25 FSAR-SP Section 11.5.2.3.2.3 26 FSAR-SP Section 11.5.2.3.2.2 Page 15 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Dtb is the REC 16.11.2.1 dose rate limit of 500 mrem/yr, conservatively interpreted as a continuous release over a one year period; Fs is the safety factor; a conservative factor used to compensate for statistical fluctuations and errors of measurement. (For example, Fs = 0.5 corresponds to a 100% variation.) Default value is Fs = 0.1. Fa is the allocation factor which will modify the required dilution factor such that simultaneous gaseous releases may be made without exceeding the limits of REC 16.11.2.1. Rtb is a factor used to convert dose rate to the effluent concentration as measured by the effluent monitor, in (!-lCi/cc) per (mrem/yr) to the total body, determined according to: Eq.lO Where: C is the reading of a noble gas monitor corresponding to the sample radionuclide concentrations for the release. Concentrations are determined in accordance with SP Table 16.11-4.The mixture of radionuclides determined via grab sampling of the effluent stream or source is correlated to a calibration factor to determine monitor response. The monitor response is based on concentration, not release rate, and is in units of (1-1Cilcc); X/Q is the highest calculated annual average relative concentration for any area at or beyond the Site Boundary in (secfm3) (Table 10, Table 11, Table 12, and Table 13); Ki is the total body dose factor due to gamma emissions for each identified noble gas radionuclide, in (mrem/yr) per (1-1Ci/m 3) (Table 3); and Qi is the rate of release of noble gas radionuclide, i, in (!-lCi/sec). Qi is calculated as the product of the ventilation path flow rate and the measured activity of the effluent stream as determined by sampling. 3.2.2. Skin Dose Rate Setpoint Calculation To ensure that the limits of REC 16.11.2.1 are met, the alarm/trip setpoint based on the skin dose rate is calculated according to: Where: Fs and Fa are as previously defined; 55 ::; DSRSFSFO Eq.ll Page 16 of 72 INFORMATION USE August 2012 Ss is the alarm/trip setpoint based on the skin dose rate; APA-ZZ-01 003 Rev. 019 Ds is the REC 16.11.2.1 dose rate limit of 3000 mrem/yr, conservatively interpreted as a continuous release over a one year period; and Rs is the factor used to convert dose rate to the effluent concentration as measured by the effluent monitor, in (f..!Ci/cc) per (mrem/yr) to the skin, determined according to: R, = C -c[ ( X/0) L,+ l.lM,) Q, l Eq.12 Where: Li is the skin dose factor due to beta emissions for each identified noble gas radionuclide, in (mrem/yr) per (f..!Ci/m 3); 1.1 is a factor of units conversion; 1 mrad air dose = 1.1 mrem skin dose; and Mi is the air dose factor due to gamma emissions for each identified noble gas radionuclide, in (mrad/yr) per (f..!Ci/m 3). C, (X/Q), and Qi are previously defined. 3.3. Calculation of Dose and Dose Rate from Gaseous Effluents 3.3.1. Dose Rate from Gaseous Effluents The following methodology is applicable to the location (Site Boundary or beyond) characterized by the values of the parameter X/Q which results in the maximum total body or skin dose rate. In the event that the analysis indicates a different location for the total body and skin dose limitations, the location selected for consideration is that which minimizes the allowable release values. 27 The factors Kj, Lj, and Mi relate the radionuclide airborne concentrations to various dose rates, assuming a semi-infinite cloud model. 3.3.1.1.

(X/Q) is as previously defined. The dose parameter (Ri) includes the internal dosimetry of radionuclide, i, and the receptor's breathing rate, which are functions of the receptor's age. The child age group has been selected as the limiting age group. All radiodines are assumed to be released in elemental form. 30 Ri values were calculated according to: 31 29 NUREG-0133, Section 5.2.1 30 NUREG-0133, Section 5.2.1 31 NUREG-0133, Section 5.2.1.1 R; = K' (BR} DFA; Eq.16 Page 18 of 72 INFORMATION USE August 2012 Where: K' is a factor of units conversion factor: 1 x1 0 6 pCi/f.!Ci; BR is the breathing rate from Regulatory Guide 1.1 09, Table E-5 (m 3/yr); APA-ZZ-01 003 Rev. 019 DFAi is the maximum organ inhalation dose factor for the i 1 h radionuclide, in (mrem/pCi). The total body is considered as an organ in the selection of DFAj. 32*33 The results of periodic tritium, iodine and particulate samples of the Unit Vent and Radwaste Vent are used to verify the dose rate limit was not exceeded for the period during which the samples or composite samples were obtained. 3.3.2. Dose Due to Gaseous Effluents 3.3.2.1. Air Dose Due to Noble Gases The air dose at the Site Boundary due to noble gases is calculated according to the following methodology: 34 During any calendar quarter, for gamma radiation: Dg=3.17E-08I[M; (x!a)a;J I Eq.17 During any calendar quarter, for beta radiation: Db = 3.17£-08 Ni ( x;a) O; J 10 mrad I Eq.18 During any calendar year, for gamma radiation: Dg = 3.17£-08 I[ M; ( x;a) 0; J 10 mrad I Eq.19 During any calendar year, for beta radiation: Db =3.17£-08 I[ Ni (x!a) 0; J I Where: 32 Regulatory Guide 1.1 09, Appendix E, Table E-9 33 ZZ-48 34 NUREG-0133, Section 5.3.1 Eq.20 Page 19 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 0 9 is the air dose in mrad, from gamma radiation due to noble gases released in gaseous effluent; Db is the air dose in mrad, from beta radiation due to noble gases released in gaseous effluents; N 1 is the air dose factor due to beta emissions for each identified noble gas radionuclide, i, in (mrad/yr) per (f..lCifm3); Qi is the releases of noble gas radionuclides, i, in gaseous effluents, for all gaseous releases in (f..lCi). Releases are cumulative over the calendar quarter or year as appropriate. Qi is calculated as the product of the ventilation flow rate and the measured activity of the effluent stream as determined by sampling; and 3.17x1 0" 8 is the inverse of the number of seconds per year. X/Q & M 1 are as previously defined. 3.3.2.2. Dose Due to Radionuc/ides Other than Noble Gases The dose to a Member of the Public from 131 1 and 133 1, for 3 H, and all radionuclides in particulate form with half-lives greater than 8 days in gaseous effluents released to areas at and beyond the Site Boundary, is calculated according to the following expressions: During any calendar quarter: During any calendar year: Ip,,i 7.5 mrem Eq.21 Iio,,i 15 mrem Eq.22 For each pathway, j, (i.e., for inhalation, ground plane, meat, cow-milk, goat-milk, and vegetation) D1.i is calculated according to the expression: 0 1. =3.17E -B".R, ..

Qi is calculated as the product of ventilation flow rate and the measured activity of the effluent stream as determined by sampling; and 3.17x1 o-s is the inverse of the number of seconds per year. X/Q is as previously defined. Refer to Table 10, Table ll,Table 12, and Table 13 for applicability; Although the annual average relative concentration X/Q and the average relative deposition rate D/Q are generally considered to be at the approximate receptor location in lieu of the Site Boundary for these calculations, it is acceptable to consider the ingestion, inhalation, and ground plane pathways to coexist at the location of the nearest residence with the highest value of X/Q. 35 The Total Body dose from ground plane deposition is added to the dose for each individual organ. 36 3.4. Gaseous Radwaste Treatment System The gaseous radwaste treatment system and the ventilation exhaust system are available for use whenever gaseous effluents require treatment prior to being released to the environment. The gaseous radwaste treatment system is designed to allow for the retention of all gaseous fission products to be discharged from the reactor coolant system. The retention system consists of eight (8) waste gas decay tanks. Normally, waste gases will be retained for at least 60 days prior to discharge. When practicable, waste gas decay tanks are discharged outside the growing season or at night such that 14 C released from the waste gas system will not be incorporated into the ingestion pathways and will result in a lower dose to the Member of the Public. For this purpose, the growing season is defined as April 1 through November 1. 37 These systems will provide reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept ALARA. The Operability of the gaseous radwaste treatment system ensures this system will be available for use when gases require treatment prior to their release to the environment. Operability is demonstrated through compliance with REC 16.11.2.1, 16.11.2.2, and 16.11.2.3. 35 NUREG-0133, Section 5.3.1 36 Regulatory Guide 1.1 09, Appendix C, Section 1 37 Hammer, Gregory, R., "Climate of Missouri", monograph available from the National Climatic Data Center (NCDC) of the National Oceanic and Atmospheric Administration (NOAA), January, 2006. Page 21 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Projected doses (gamma air, beta air, and organ dose) due to gaseous effluents at or beyond the Site Boundary are determined each 31 days. The prior 31 day period is used to calculate compliance. This may be modified as appropriate to account for changes in radwaste treatment which may have a significant effect on the projected doses. 3.5. Dose Factors The dose conversion factors were derived from the appropriate dose conversion factors in Regulatory Guide 1.109 and other sources as necessary. 38*39 Particulate nuclides with a life of less than 8 days are not considered. 40 90 Y, 140 La, and 144 Pr are included because the parent half-life is greater than 8 days, and equilibrium is assumed. 4. Dose and Dose Commitment from Uranium Fuel Cycle Sources 4.1. Calculation of Dose and Dose Commitment from Uranium Fuel Cycle Sources The annual dose or dose commitment to a Member of the Public for Uranium Fuel Cycle Sources is determined as:

• Dose to the total body and internal organs due to gamma ray exposure from submersion in a cloud of radioactive noble gases, ground plane exposure, and direct radiation from the Unit , onsite storage of low-level radioactive waste, and outside storage tanks;
• Dose to skin due to beta radiation from submersion in a cloud of radioactive noble gases, and ground plane exposure;
• Thyroid dose due to inhalation and ingestion of radioiodines; and
• Organ dose due to inhalation and ingestion of radioactive material.

It is assumed that total body dose from sources of gamma radiation irradiates internal body organs at the same numerical rate.41 The dose from gaseous effluents is considered to be the summation of the dose at the individual's residence and the dose to the individual from activities within the Site Boundary. Since the doses via liquid releases are very conservatively evaluated, there is reasonable assurance that no real individual will receive a significant dose from radioactive liquid release pathways. Therefore, only doses to individuals via airborne pathways and doses resulting from direct radiation are considered in determining compliance to 40 CFR 190.42 There are no other Uranium Fuel Cycle Sources within 8 km of the Callaway Plant. 38 ZZ-78 39 ZZ-250 40 Inspection Report 50-483/92002 (DRSS) 41 NUREG-0543, Section Ill, page 8 42 NUREG-0543, Section IV, page 9 Page 22 of 72 INFORMATION USE August 2012

4.1.1. Identification

of the Member of the Public APA-ZZ-01003 Rev. 019 The Member of the Public is considered to be a real individual, including all persons not occupationally associated with the Callaway Plant, but who may use portions of the plant site for recreational or other purposes not associated with the plant. 43 Accordingly, it is necessary to characterize this individual with respect to his utilization of areas both within and at or beyond the Site Boundary and identify, as far as possible, major assumptions which could be reevaluated if necessary to demonstrate continued compliance with 40 CFR 190 through the use of more realistic assumptions. 44*45 The evaluation of Total Dose from the Uranium Fuel Cycle should consider the dose to two Critical Receptors: (a) The Nearest Resident, and (b) The Critical Receptor within the Site Boundary.

4.1.2. Total

Dose to the Nearest Resident The dose to the Nearest Resident is due to plume exposure from noble gases, ground plane exposure, and inhalation and ingestion pathways. It is conservatively assumed that each ingestion pathway (meat, milk, and vegetation) exists at the location of the Nearest Resident. It is assumed that direct radiation dose from operation of the Unit and storage of radioactive material, and dose from gaseous effluents due to activities within the Site Boundary is negligible for the Nearest Resident. The total Dose from the Uranium Fuel Cycle to the Nearest Resident is calculated using the methodology discussed in Section 3, using concurrent meteorological data for the location of the Nearest Resident with the highest value of X/0. The location of the Nearest Resident in each meteorological sector is determined from the Annual Land Use Census conducted in accordance with the Requirements of REC 16.11.4.2.

4.1.3. Total

Dose to the Critical Receptor within the Site Boundary The Union Electric Company has entered into an agreement with the State of Missouri Department of Conservation for management of the residual lands surrounding the Callaway Plant, including some areas within the Site Boundary. Under the terms of this agreement, certain areas have been opened to the public for low intensity recreational uses (hunting, hiking, sightseeing, etc.) but recreational use is excluded in an area immediately surrounding the plant site (refer to Figure 4.1 ). Much of the residual lands within the Site Boundary are leased to area farmers by the Department of Conservation to provide income to support management and development costs. Activities conducted under these leases are primarily comprised of farming (animal feed), grazing, and forestry.46*47*48 43 NUREG-0133, Section 3.8 44 NUREG-0543, Section IV, page 9 45 NUREG-0543, section Ill, page 6 46 Environmental Report, OLS, Section 2.1.2.3 Page 23 of72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Based on the utilization of areas within the Site Boundary, it is reasonable to assume that the critical receptor within the Site Boundary is a farmer, and that his dose from activities within the Site Boundary is due to exposure incurred while conducting his farming activities. The current tenant has estimated that he spends approximately 1100 hours per year working in this area 49. Occupancy of areas within the Site Boundary is assumed to be averaged over a period of one year. Any reevaluation of assumptions should consider only real receptors and real pathways using realistic assumption, and should include a reevaluation of the occupancy period at the locations of real exposure (e.g. a real individual would not simultaneously exist at each point of maximum exposure). 4.1.3.1. Total Dose to the Farmer from Gaseous Effluents The Total Dose to the farmer from gaseous effluents is calculated for the adult age group using the methodology discussed in Section 3, utilizing concurrent meteorological data at the farmer's residence and historical meteorological data from Table 10 for activities within the Site Boundary. These dispersion parameters were calculated by assuming that the farmer's time is equally distributed over the areas farmed within the Site Boundary, and already have the total occupancy of 1100 hours/year factored into their value. 50 As a first approximation, the farmer's residence is assumed to be at the location of the Nearest Resident as shown in Table 10 and Table 11. The gaseous effluents dose at the farmer's residence is due to plume exposure from Noble Gases and the ground plane, inhalation, and ingestion pathways. For conservatism, it is acceptable to assume that all of the ingestion pathways exist at this location. It is assumed that food ingestion pathways do not exist within the Site Boundary, therefore the gaseous effluents dose within the Site Boundary is due to plume exposure from Noble Gases and the ground plane and inhalation pathways. 4.1.3.1.1. Direct Radiation Dose The direct radiation dose to the Member of Public due to activities within the Site Boundary is insignificant. 51 47 Environmental Report, OLS, Section 2.1.3.3.4 48 Management Agreement for the Public Use of Lands, Exhibit A. 49 Private communication, H.C.

5. Radiological Environmental Monitoring APA-ZZ-01 003 Rev. 019 5.1. Description Of The Radiological Environmental Monitoring Program The Radiological Environmental Monitoring Program is intended to act as a background data base for pre-operation and to supplement the radiological effluent release monitoring program during plant operation.

Radiation exposure to the public from the various specific pathways and direct radiation can be adequately evaluated by this program. Some deviations from the sampling frequency may be necessary due to seasonal unavailability, hazardous conditions, or other legitimate reasons. Efforts are made to obtain all required samples within the required time frame. Any deviation(s) in sampling frequency or location is documented in the Annual Radiological Environmental Operating Report. REMP sampling locations that use meteorological sectors and or distance from the plant site were verified as described in HPCI 99-01. Sampling, reporting, and analytical requirements are given in FSAR-SP Tables 16.11-7, 16.11-8, and 16.11-9. Airborne, waterborne, direct radiation, and ingestion samples collected under the monitoring program are analyzed by an independent, third-party laboratory. With the exception of direct radiation, the laboratory is required to participate in an Interlaboratory Analyses Program per Reg. Guide 4.15. 52 The laboratory participates in an Interlaboratory crosscheck program administered by Environmental Resources Associates (ERA), Mixed Analyte Performance Evaluation Program (MAPEP), or equivalent program. This participation includes all of the determinations (sample medium-radionuclide combination) that are both offered by ERA and/or MAPEP and are also included in the environmental monitoring program. 5.2. Performance Testing Of Environmental Thermoluminescence Dosimeters Dosimeters used for monitoring of direct radiation dose in the Radiological Environmental Monitoring Program are tested for accuracy and precision to demonstrate compliance with the applicable portions of Regulatory Guide 4.13. 6. Annual Average And Short Term Atmospheric Dispersion Parameters

6.1. Atmospheric

Dispersion Parameters The dispersion values presented in Table 10 and Table 11 were determined through the analysis of on-site meteorological data collected during the three year period of May 4, 1973 to May 5, 1975 and March 16, 1978 to March 16, 1979. 6.1.1. Dispersion Estimates The variable trajectory plume segment atmospheric transport model MESODIF-11 (NUREG/-CR-0523) and the straight-line Gaussian dispersion model XOQDOQ (NUREG/CR2919) were used for determination of the long-term atmospheric dispersion 52 Regulatory Guide 4.15, rev. 1, section 6.3.2 Page 26 of 72 INFORMATION USE August 2012 APA-ZZ -01 003 Rev. 019 parameters. A more detailed discussion of the methodology and data utilized to calculate these parameters can be found elsewhere. 53 The Unit Vent and Radwaste Building Vent releases are at elevations of 66.5 meters and 20 meters above grade, respectively. Both release points are within the building wake of the structures on which they are located, and the Unit Vent is equipped with a rain cover which effectively eliminates the possibility of the exit velocity exceeding five times the horizontal wind speed. All gaseous releases are thus considered to be ground-level releases. 54 6.1.2. Determination of Dispersion Estimates for Special Receptor Locations Calculations utilizing the PUFF model were performed for 22 standard distances to obtain the desired dispersion parameters. Dispersion parameters at the Site Boundary and at special receptor locations were estimated by logarithmic interpolation according to: 5 5 Where: X=X 1 (d/d 1 t Eq.24 In ( X 2/X 1) 8 = --':--'=---=-::- In (d 2/d 1) Eq.25 X1, X2 are the atmospheric dispersion parameters at distance d 1 and d 2 , respectively, from the source. The distances d1 and d2 were selected such that they satisfy the relationship d 1<d<d 2. 6.1.3. Atmospheric Dispersion Parameters for Farming Areas within the Site Boundary The dispersion parameters for farming areas within the Site Boundary are intended for a narrow scope application; that of calculating the dose to the current farmer from gaseous effluents while he conducts farming activities within the Site Boundary. For the purpose of these calculations, it was assumed that all of the farmer's time, approximately 11 00 hours per year, is spent on croplands within the Site Boundary, and that his time is divided evenly over all of the croplands. Fractional acreage/time -weighted dispersion parameters were calculated for each plot as described in calculation ZZ-67. The weighted dispersion parameters for each plot were summed (according to type) in order to produce a composite value of the dispersion parameters which are presented in Table 10 and Table 11. These dispersion parameters therefore represent the distributed activities of the farmer within the Site Boundary and his estimated occupancy period. 6.2. Annual Meteorological Data Processing 53 FSAR-SA Section 2.3.5 54 BLUE 1285 55 FSAR-SA 2.3.5.2.1.2 Page 27 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 The annual atmospheric dispersion parameters utilized in the calculation of doses for demonstration of compliance with the numerical dose objectives of 10 CFR 50, Appendix I, are determined using computer codes and models consistent with XOQDOQ. 56 These codes have been validated and verified by a qualified meteorologist prior to implementation. Multiple sensors are utilized to ensure 90% valid data recovery for the wind speed, wind direction, and ambient air temperature parameters as required by Regulatory Guide 1.23. The selection hierarchy is presented in Table 14. The vertical height of the highest adjacent building, V, used to perform concurrent year annual average atmospheric dispersion X/Q calculations is 169.16 meters. Meteorological Data is periodically verified to ensure valid data is being collected.

The quantity of 14 C discharged can be estimated 65 by sample measurements, or by use of a normalized 14 C source term and scaling factors based on power generation, 66 or by use of the GALE code, 67 or by use of the EPRI site specific or proxy methodologies. 68 Any of these methodologies is acceptable for estimating the 14 C discharged in gaseous effluents. Assumptions

1. The total quantity of 14 C produced during the year is assumed to be released during the year in which it was produced.

2. For conservatism, it is assumed that aii 14 C produced is released in gaseous effluents.

3. The dose contribution of 14 C from liquid effluents is much less than that contributed by gaseous effluents, therefore evaluation of 14 C in liquid effluents is not required.

69 4. The dose to the Member of the Public is determined in accordance with the methodology and parameters in Regulatory Guide 1.1 09. 5. 14 C has a long half-life with respect to the transit time. 14 C is discharged as CH 4 or C0 2 gas and does not deplete or undergo chemical change before it reaches the receptor location. Therefore the appropriate dispersion parameter is X/Q (undecayed and undepleted).

6. The inhalation pathway is assumed to exist at the Nearest Residence location with the highest value of X/Q as determined by the annual Land Use Census. 7. The ingestion pathways are assumed to exist at the nearest receptor location with the highest value of X/Q as determined by the annual Land Use Census. 8. 14 C is not a gamma-emitting nuclide; therefore the ground plane pathway is negligible.

9. It is assumed that the child age group exists at the Nearest Residence and ingestion pathway locations.

10. Only 14 C0 2 discharged during the period of photosynthesis is considered for the ingestion pathways.

11. All of the 14 C produced is assumed to contribute to the inhalation dose pathway, regardless of chemical form. 65 Regulatory Guide 1.21, rev. 2, Section 1.9 66 NCRP Report 81 67 NUREG-0017 68 EPRI TR-1 021106, Section 4. 69 Regulatory Guide 1.21, rev. 2, Section 1.9 Page 55 of 72 INFORMATION USE August 2012 1 Applicable Dose Limits APA-ZZ-01003 Rev. 019 10 CFR 50, Appendix I, states, "The calculated annual total quantity of all radioactive iodine and radioactive material in particulate form above background to be released from each light-water-cooled nuclear power reactor in effluents to the atmosphere will not result in an estimated annual dose or dose commitment from such radioactive iodine and radioactive material in particulate form for any individual in an unrestricted area from all pathways of exposure in excess of 15 millirems to any organ." 70 Radiological Effluent Control (REC) 16.11.2.3 limits the annual dose to the Member of the Public from 131 1, 133 1, 3 H, and particulates with half-lives greater than 8 days released in gaseous effluents to 15 mrem to any organ. 71 14 C is released as a gas in the form of CH 4 or C0 2 and is not a radioiodine, tritium, or particulate, therefore the design objectives in 10 CFR 50, Appendix I and the limits of REC 16.11.2.3 do not apply to 14 C. 10 CFR 20.1301(a)(1) limits the annual TEDE dose to the Member of the Public to 100 mrem. 40 CFR 190.1 O(a) limits the total annual dose from the uranium fuel cycle to the Member of the Public to 25 mrem to the whole body or any organ. 40 CFR 190 is implemented by REC 16.11.3.1.

This limit includes dose from the release of gaseous effluents to areas at or beyond the Site Boundary, the dose from gaseous effluents due to activities within the Site Boundary, and the dose from direct radiation. The methodology for calculating the total annual dose from the uranium fuel cycle is provided in Section 4. Estimation of 14 C in Gaseous Effluents 14 C exists in all PWR systems, and any location or system that contains tritium most likely also will contain 14 C in some chemical form. Measurements of 14 C concentrations in various liquid systems have been performed, and some of the reported data are included in EPRI TR-1 021106.72 As a general rule, 14 C in the primary coolant is essentially all organic with a significant fraction as a gaseous species. If the RCS liquid or gas is exposed to an oxidizing environment, such as during the forced oxidation during the shutdown evolution and during refueling outages, a slow transformation from an organic to an inorganic chemical form can occur. Dissolved nitrogen gas and ammonia in the RCS could contribute to the 14 C source term. The dissolved nitrogen could become significant in the latter stages of the fuel cycle due to the introduction of increased quantities of non-borated water for boron dilution. Callaway maintains a hydrogen gas overpressure on the RCS which effectively eliminates dissolved nitrogen gas and ammonia in the RCS, therefore the RCS ammonia concentration is assumed to be 0. In general, 14 C is produced in light water moderated nuclear power reactors by 14 N(n,p)14 C reactions with nitrogen impurities in the coolant and by 17 0{n,a)14 C reactions in the coolant. 14 C produced in a nuclear power reactor can be released directly to the environment from the coolant in a gaseous form or in much smaller quantities as liquid effluents. 73 Kunz estimated the fraction of 14 C in liquid and solid wastes at 70 10 CFR 50, Appendix I, section II, paragraph C 71 NUREG-1301, REC 3.11.2.3 72 EPRI TR-1 021106, Section 4.1 73 IAEA Report 421, Section 3.1.3 Page 56 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 <5% of that in gaseous discharges

74. Regulatory Guide 1.21 states that the dose contribution from 14 C in liquid discharges is insignificant and evaluation of 14 C released in liquid effluents is not required.

75 The release and removal pathways from the primary coolant include VCT venting, boron dilution, inventory buildup on the letdown demineralizers and filters, and reactor coolant leakage. Letdown system removal is approximately 1 Ci/yr. 76 The 14 C production balance is shown in Figure 1. __________________ System Inventory RCS Waste Gase System Fuel Pool RWST Radwaste Systems IX resins Filters Charcoal Gaseous Release I Waste Gas System 1 Containment Vent Containment Purge Aux. Bldg. Ventilation Fuel Bldg. Ventilation Figure 1: 14 C Production Balance Chemical Form of 14 C in Gaseous Effluents Liquid Release Discharge Monitor Tanks Solid Release Primary System IX resins & filters Fuel pool IX resins & filters Radwaste IX resins Since the PWR operates with a reducing chemical environment, most, if not all, of the 14 C species initially produced are in the reduced, i.e., organic, form and contain only a single carbon atom. Possible species include methane C 4 CH4), methanol C 4 CH30H), formaldehyde (H 2 14 C=O or the gem-diol H 2 14 C(0Hh ), and formic acid (H 14 COOH). In theory, the only ionic species produced will be formic acid (H 14 C0 2 H) , and some or all of the formic acid will be removed by the letdown demineralizers. Formaldehyde is soluble in water and may partially be chemisorbed on the ion exchange resin. A quasi-equilibrium is established in the coolant between the initially produced species and other possible species in the reactor coolant. The most chemically reduced species and probably the most prevalent species is 14 CH 4 which partitions between the liquid and gas phases in the VCT and pressurizer. 77 The airborne 14 C released from PWRs is predominantly hydrocarbons (75-95%), mainly methane (CH 4), with only a small fraction in the form of C0 2. 78* 79 Regulatory Guide 1.21 states that 14 C releases in PWRs occur primarily as a mix of organic carbon and C0 2 in gaseous waste from the waste gas system. 80 NUREG-0017 81 74 Kunz, 1985 75 Regulatory Guide 1.21, rev. 2, section 1.09 76 EPRI TR-1 021106, Section 4.1 77 EPRI TR-1 021106, Section 4.1 78 IAEA Report 421, Section 3.1.3 79 Neeb, section 4.2.4 80 Regulatory Guide 1.21, rev. 2, section 1.09 81 NUREG-0017, Section 2.2.25.2 Page 57 of 72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 concludes that 16.4% of the 14 C produced in a PWR will be released via the waste gas processing system, and the remainder, 83.6%, from the Reactor Building and the Auxiliary Building. Due to the presence of high temperature hydrogen recombiners in the Callaway waste gas system, 100% of the 14 C released through the waste gas system is assumed to be released from the waste gas decay tanks in the oxidized, i.e., inorganic form as C0 2. The 14 C released from the unit vent is assumed to be in the reduced (organic) form as CH 4 , therefore 16.4% of the 14 C produced is released through the Waste Gas Decay tanks (WGDT) as C02, and 83.6% is released via the Unit Vent as CH4. _______ 16.4% Waste Gas System Waste Gas Decay Tanks C02 Figure 2: 14 C Gaseous Discharge Balance 14 C Source Term Estimation 83.6% Plant Vents Containment Vent Containment Purge Aux.

• Sampling and analysis of effluent streams
• Use of normalized 14 C source term and scaling factors based on power generation, e.g., NCRP Report 81 113
• Use of the PWR GALE code 114 Callaway Plant effluents have not been sampled for 14 C. NCRP Report 81, Table 3.3 states that the total 14 C production rate for a PWR without reactor coolant nitrogen is 6 Ci/GWe-yr.

Assuming a conversion of 0.34 GWJGW 1 h, the expected 14 C production rate is 2 Ci/GW 1 h-yr or 7.2 Ci/EFPY for Callaway. The PWR GALE code does not calculate the quantity of 14 C produced, but instead assigns a value of 7.3 Ci/yr for every PWR without regard for power level, reactor coolant nitrogen concentration, or waste gas system design and operation. Using the EPRI methodology and the neutron flux distribution for Cycle 18, the 14 C production for Callaway is 13.2 Ci/EFPY.115 The 14 C production calculated using the EPRI methodology is therefore conservative with respect to the 14 C production calculated using NCRP Report 81 and the PWR GALE code. EPRI Proxy PWR Methodology The average 14 C production rate for Westinghouse PWRs is 3.4 Ci/ GW 1 h-yr 116. Callaway is rated at 3.565 GWth (3565 MW 1 h), therefore, the 14 C production rate based on the proxy PWR is 12.1 Ci/ EFPY. The 14 C production calculated using the EPRI proxy methodology is therefore conservative with respect to the 14 C production calculated using NCRP Report 81 and the PWR GALE code. 112 Regulatory Guide 1.21, Section 1.9 113 NCRP Report 81 114 NUREG-0017 115 HPCI 11-02 116 EPRI TR-1021106, Section 4.8 and Appendix D Page 66 of72 INFORMATION USE August 2012 Appendix B: Record of Revisions 117 Rev.

Added action to be taken when the particulate and/or iodine grab sampler is not operable. Section 3.2: Added setpoint calculation for GL-RE-202. Section 3.2.1 and 3.3.2.2: Changes were made to correct typographical errors and have no technical impact. Section 3.4: Revised projected gas dose calculation to use previous 31 day cumulative doses. Section 3.5: Removed the word secular from "secular equilibrium" since the equilibrium mode could be secular or transient depending on the isotope. Table 6.2: Added Laundry Decon Facility Dryer Exhaust to title of table since these will be the dispersion factors used for this release point. Rev. No. 10 Date December 20, 1999 Section 3.1: Added explanation that GL-RE-202 only monitors particulate. Section 3.2: Changed Laundry Decon Facility Exhaust Monitor setpoint to less than or equal to 2000 cpm above equilibrium background with a maximum allowed background of 2000 cpm as calculated in HPCI 99-05. Tables 6.1, 6.2, 6.3: Updated values as calculated in HPCI 99-02. Section 5.1: Defined how REMP sample locations were determined. Removed reference to Plant Operating manual since it no longer exists. Rev. No. 11 Date December 22, 1999 Page 69 of72 INFORMATION USE August 2012 APA-ZZ-01 003 Rev. 019 Changes required to go from old Technical Specifications to Improved Technical Specifications (ITS).

name of Annual Radiological Effluent Release Report to Effluent Release Report as stated in ITS. Added liquid releases are limited to 10 times the Appendix B, Table 2, Column 21imits Per FSAR CN 98-041 supporting implementation of ITS. Rev. No. 12 Date December 01, 2000 Section 2.1 and 2.2.1: Updated 1 OCFR20, Appendix B, Table II, Column 2 reference to the new 1 OCFR20 format. Corrected typo for "f', flow setpoint should be undiluted waste flow rate. Section 3.2.1: Corrected typo, default value for safety factor should be 0.1. Section 5.1: Updated crosscheck program used to EML since EPA program is no longer available. Section 6.2: Added vertical height of highest adjacent building used to perform concurrent year annual average atmospheric dispersion (X/Q) calculations and reference for this value. This information should be documented in the ODCM. Added responsibility for validation of meteorological data, since responsibility has changed from engineering to HPTS. Section 1 0.1.1: Revised to require a summary of Major Radwaste System changes to be included in the annual report. This was done to be consistent with FSAR 16.11.5.2.Several changes were made throughout the procedure to correct typographical errors and have no technical impact. Rev. No. 13 Date September 19, 2002 Section 3.2: Revised to implement the approved OL 1218, Rev. 1; License Amendment no. 152 allowing equipment hatch and emergency air lock to remain open during refueling activities (FSAR CN-01-030 and CN-02-049). The amendment eliminated FSAR 16.11.2.4.1 B and subsequently deleted the core alteration setpoint value 5.0 E-3 f.!Ci/cc for Containment Purge Monitors GT -RE-22 and GT -RE-33. The alarm setpoints for the Containment Purge Monitors will be based on the methodology described in Section 3 of the ODCM. Rev. No. 14 Date June 17, 2003 Revised Table 2.1 (Ingestion Dose Commitment Factor for Adult Age Group) to include dose factors for Pr-144. (CARS 200303251 ).Revised Section 4.1.3.1 to adjust the Farmer's residence (critical receptor) from 3830 meters in theSE sector to 2897 meters in the NNW sector. The Farmer's residence (critical receptor) was changed in 2002 to a location directly across the street from the Nearest residence. For conservatism and ease in calculation, Table 6.1 and 6.2 were revised making the distances and dispersion parameters for the Farmer's residence (critical receptor) and the Nearest residence the same. Revised section 7.2 to reference Table 6.6. Revised section 10.2.2 to remove the requirement for QA department review of the ODCM for reach revision (CARS 200304509). Added a reference to 11.14.14, Calculation HPCI 03-004 (Rev. 0), "Calculation of Liquid Effluent Dose Commitment factor for Pr-144 (Air) for the Adult Age Group", June, 2003. Rev. No. 15 Date December 9, 2004 Reformatted references to FSAR-SP Chapter 16.11 in section 1, 2.1.1, 2.1.2, 2.2.1, 2.3, 2.4.2, 2.5, 2.6, 3.1, 3.2.1, 3.5, 5.1, 7.1, 7.2, and 9. References to 63 Ni were added to section 2.2.1 for the calculation of ECVSUM, section 2.3, and described in section 2.6 since it is an exception to non-gamma emitters not listed in FSAR-SP Table 16.11-1. 63 Ni was added to the ODCM based on previous 10 CFR 61 sample results and 2"d quarter liquid composite analyses. Consolidated references listed in section 2.4.2 and 2.6 for the site related ingestion dose commitment factors (Air of Table 2.1 into HPCI 04-06, Revision 1. References to HPCis 95-004 (Ref: 11.14.13) and 03-004 (Ref: 11.14.14) were deleted and replaced with HPCI 04-06, Revision 1 which is now listed as Ref: 11.14.13. Added 63 Ni and 122 Sb to Table 2.1-INGESTION DOSE COMMITMENT FACTOR (Air) FOR ADULT AGE GROUP. Revised the reference for Table 2.1 to 11.14.13. Corrected a typo in section 3.1.2 referring to the Radwaste Building Vent Page 70 of 72 INFORMATION USE August 2012 APA-ZZ-01003 Rev. 019 system designator as GT vs. GH (CAR 200406851 ). References 11.19 and 11.20 were deleted in section 4.1.3.1.1. Reference 11.18 was changed to MICROSHIELD (Grove Engineering, Inc.) vs. ISOSHLD. Reference 11.24 in section 4.1.3.1.3 was corrected to 11.18. Section 5.1 and 5.2 were revised to indicate that the Radiological Environmental Monitoring Program TLDs will be processed and provided by a vendor laboratory beginning in the first quarter of 2005. Section 5.2 was revised to delete reference 11.14.10 which refers to HPCI 88-08, "Performance Testing of the Environment TLD System at Callaway Plant", August 1989. Reference 11.14.7 was corrected with HPCI 87-10 vs. 88-10. Revised Table 6.1, Note (c) to reference FSAR Table 2.3-83 vs. Table 2.3-82. Revised Table 6.1 and 6.2 Note (b) to reference data is from the 2002 Land Use Census. Changed and/or corrected the Skin dose factor (Li) units in Table 3.1 (Dose Factor for exposure to a Semi-Infinite Cloud of Noble Gases) to mrem/yr per uCi/m 3. Revised section 3.3.1.2: Added units for the term BR in m 3/yr. Removed paragraph in section 3.3.2.2 that describes actions for implementing the use of appropriate R 1 ,i,j values. This paragraph was taken directly from section 5.3.1 of NUREG 0133, U.S. Nuclear Regulatory Commission, "Preparation of Radiological Effluent Technical Specification for Nuclear Power Plants", USNRC NUREG-0133, Washington, D.C. 20555, October, 1978. This paragraph does not apply since the use of pathways is already considered as described in sections 4.1.2 and 4.1.3.1. Revised note (c) of Table 6.1 to reference FSAR-SA Table 2.3-83. Revised note (a) from Table 6.1 to reference FSAR-SA Table 2.3-82. In addition, revised Note (b) from Table 6.1 to reference data taken from the 2002 Land Use Census. Revised Notes (a) and (c) from Table 6.2 to reference FSAR-SA Table 2.3-84 and 2.3-81 respectively. Added a 0.95 conservatism factor to section 2.2.3 Calculation of Liquid Effluent Monitor Setpoint. This will conservatively reduce the liquid monitor setpoint to further ensure the section 4.4.1 of NUREG 0133, U.S. Nuclear Regulatory Commission, "Preparation of Radiological Effluent Technical Specification for Nuclear Power Plants", USNRC NUREG-0133, Washington, D.C. 20555, October, 1978 which states the alarm and trip setpoints for each instrument channel listed in Table 3.3-11 should be provided and should correspond to a value(s) which represents a safe margin of assurance that the instantaneous liquid release limit of 10 CFR Part 20 is not exceeded. A determination was made lAW T/S 5.5.1 that the associated changes with Revision 15 maintain the levels of radioactive effluent control required by 10 CFR 20.1302, 40 CFR 190, 10 CFR 50.36a, and 10 CFR 50 Appendix I, and not adversely impact the accuracy or reliability of effluent, dose, or setpoint calculations. Rev. No. 16 Date December 1, 2005 Section 5.1 was revised to remove an invalid requirement that a third-party laboratory performing analysis specifically state the Interlaboratory Comparison (crosscheck) requirements for the Radiological Environmental Monitoring Program (REMP) contract lab. Reference 11.14.14 to Reg. Guide 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operations)- Effluent Streams and the Environment, was added to provide supporting documentation for contract lab Interlaboratory Comparison requirements. Additional information on REMP contract lab participation in Interlaboratory Comparisons was also added in section 5.1. (CAR 200500891) Revised reference 11.14. 7 by adding normalization and standardization factors for radio nuclides listed in Table 2.1 of the ODCM that were not included in the original calculation. Added section 4.1.3.1.4 to describe direct dose to a Member of the Public from the Old Steam Generator Storage Facility (OSGSF). Reworded step 4.1.2 to describe the sources of direct radiation from "outside storage tanks" to "storage of radioactive material". Revised section 4.1.3.1.2 to include and describe direct dose calculations in support of Modification 03-1008, Equipment Hatch Platform and Missile Shield Modification. Reference 11.14.10 was added to reference direct dose calculation to the Member of the Public from Modification 03-1008. Revised section 4.1.3.1.3 to include and describe direct dose calculations from the Radwaste Yard RAM storage and Stores II. Reference 11.19 and 11.20 were added to reference direct dose calculations to the Member of the Public from RAM storage at Stores II and the Radwaste Yard. A determination was made lAW T/S 5.5.1 that the associated changes with Revision 16 maintain the levels of radioactive effluent control required by 10 CFR 20.1302, 40 CFR 190, 10 CFR 50.36a, and 10 CFR 50 Appendix I, and not adversely impact the accuracy or reliability of effluent, dose, or setpoint calculations. Page 71 of 72 INFORMATION USE August 2012 Rev. No. 17 Date March 14, 2007 APA-ZZ -01 003 Rev. 019 Section 2.4.1 was revised Per CAR 200701309 to state that no potable water intakes exist within 10 miles of the plant discharge point. This is due to the fact that the Annual Land Use Census ensures no newly developed potable water intakes within 10 miles of the plant discharge Per FSAR-SP Chapter 16.11.4.2c. Section 2.4.2 was revised to add reference 11.6.18 to CAR 200700053 which provides documentation of an evaluation of the site specific mixing factor for liquid effluents. Modification 06-0061 reconfigured the plant discharge terminus at the Missouri River. The modification was completed in January 2007. Rev. No. 18 Date October 11, 2007 Revised Table 6.5 was revised to reflect upgrade/replacement of the primary meteorological tower instrumentation as per Modification Package 04-1020. Section 2.4.2 was revised to remove the discussion of the nearest municipal potable water intake downstream from the liquid effluent discharge point as being located near the city of St. Louis, Missouri, approximately 78 miles downstream. Since the Land Use Census annually verifies no potable water intakes within 1 0 miles -this discussion was deemed inappropriate in describing methodology for calculating dose to the public from liquid effluents. In addition, the distance referenced as not having potable water intakes downstream of the plant discharge was changed for consistency with section 2.4.1 and the Land Use Census. Rev. No. 19 Date August, 2012 Converted to Word 2010, including appropriate formatting changes and cross-referencing for the conversion. Deleted all references to the obsolete Commitment Tracking System (COMN) and all hidden text for the obsolete hidden text referencing system. Added level of use. (CAR 201104163, Action 1) Section 3.4-Added dose reduction controls for discharge of 14 C from the waste gas system and defined the growing season. Section 3.5-Deleted statement that non-gamma emitting nuclides not listed in the FSAR-SP Table 16.11.4 are not considered in dose calculations. Eliminated Sections 4.1.3.1.1, 4.1.3.1.2, 4.1.3.1.3, and 4.1.3.1.4-direct radiation dose is negligible; refer to HPCI 12-06. Section 5.2-changed to allow use of dosimeters other than TLDs. Section 6.1-Deleted discussion of short-term X/Q processing and the slope factor and deleted the associated table of 'S' factors. Section 6.2-Deleted designation of responsibilities for met data review. (CAR 201104163, Action 1) Section 10.2-changed to align with T/S 5.5.1. CAR 201104163, Action 2) Corrected the department title to align with organizational structure. (CAR 201104163, Action 1 ). Table 10 and Table 11-The dispersion parameters for the Farmer's residence were removed. As a first approximation, the dispersion parameters for the Nearest Residence will be used for the Farmer's residence. Appendix A-Appendix A was added to describe the calculation of the production of 14 C and the calculation of dose from 14 C in gaseous effluents. (CAR 2011 04163) 63 Ni was added to the gaseous effluent inhalation pathway and ingestion pathways dose factor tables. Values for 63 Ni are from APA-ZZ-01 003, rev. 4. (CAR 2011 04197). Adult ingestion dose factors removed. Ingestion dose pathway removed from Table 13 for activities inside the Site Boundary. Page 72 of72 INFORMATION USE August 2012}}
