Callaway Energy Center Annual Radioactive Report Facility Operating License NPF

-30 Docket No. 50

-483 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, 2013 to December 31, 2013. The dose s to the Member of the Public from all liquid and gaseous effluents discharged during the reporting period were small fractions of the Nuclear Regulatory Commission (NRC) and Environmental Protection Agency (EPA) regulatory limits and the Radiological Effluent Control limits in the Offsite Dose Calculation Manual (ODCM).

Callaway Energy Center 2013 Annual Radioactive Effluent Release Report 2 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 1 of Regulatory Guide 1.21, and some of the information is not readily available in the format recommended by revision 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

-1A and A-1B. All gaseous effluent releases are considered to be ground level.

The quantity of 14 C released in gaseous effluents was calculated as described in EPRI Technical Report 1021106 a and the Callaway Energy Center Offsite Dose Calculation Manual (ODCM)

. 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.

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.

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 2013 Annual Radioactive Effluent Release Report 3 Table A- 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 /Q b , 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/Q c, as described in the ODCM. The organ dose does not include the dose from 14 C, which is listed separately

. Table A-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.

Supplemental Information Abnormal Releases or Abnormal Discharges There were no abnormal releases or abnormal discharges during the reporting period.

Non- routine Planned Discharges The March 2013 monthly gross alpha liquid composite sample was accidentally contaminated with Liquid Scintillation Counting cocktail waste. Attempts were made to analyze the March monthly composite for gross alpha, however the transmission loss was too high and the March monthly composite could not be used for the gross alpha analysis required by ODCM Table 16.11-1. The only remaining option was to analyze quarterly composite sample. The quarterly composite represents an average of the gross alpha concentration for the 1st quarter, 2013 whereas the monthly composite represents only the month of March, 2013; therefore the monthly and the quarterly composites are not equivalent samples; however, analysis of the quarterly composite was the only remaining option for recovery.

The result of the analysis of the

b A numerical value corresponding to the atmospheric transport and diffusion of gases released in gaseous effluents. is the average atmospheric concentration and Q is the effluent emission over the time interval.

c A numerical value corresponding to the deposition rate of particulate and iodine nuclides released in gaseous effluents. D is the average atmospheric deposition and Q is the effluent emission over th e time interval.

Callaway Energy Center 2013 Annual Radioactive Effluent Release Report 4 quarterly liquid composite sample (5.24E

-08 /ml) is consistent with historical results.

The Effluents Management System (EMS) software was updated with the results of the gross alpha analysis. This is documented in the Callaway corrective action program as CAR 201301930.

On April 18, 2013, a fire at the Unit Auxillary Transformer caused a loss of power to the electrical bus PA02 while on back feed. The loss of electrical power to the Auxiliary Building outlets and lighting resulted in loss of power to equipment used to sample the Unit Vent for 3H. At the time of the loss of power, the refueling canal was flooded. ODCM Table 16.11

-4, note 4 requires 3 H grab samples to be taken and analyzed at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the refueling canal is flooded. Due to the loss of power, the 3H sample was taken approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> 24 minutes late. This is documented in the Callaway corrective action program as CAR 201302923.

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

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.

Effluent Monitoring System Inoperability On 01/10/13 and on 1/11/13, while performing damper maintenance, the Unit vent flow rate dropped to <6750 standard cubic feet per minute (scfm) which is below the process flow rate necessary to maintain isokinetic sampling. The affected period is approximately 1.22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> on 1/10/2013 and 1.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> on 1/11/2013 which is short compared to the sampling period, which is one week. The sample filters were changed between the two low flow periods, therefore each period is considered a discrete event. The loss of isokinetic flow, while resulting in inaccurate sampling for the 1.22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and 1.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> has little effect due to the relative length of the sampling period.

The installed isokinetic nozzles are incapable of isokinetic sampling at unit vent flow rates <6750 scfm even with auxiliary sampling equipment

, therefore, Action 43 of FSAR/ODCM Table 16.11

-5 was not met during these two periods.

This is documented in the Callaway corrective action program as CAR 201300253 and CAR 201300289. Offsite Dose Calculation Manual Changes There were no changes to the Offsite Dose Calculation Manual during the reporting period.

Process Control Program Changes Revision 13 to APA

-ZZ-01011, Process Control Program was issued on 12

/19/13. This revision added clarification that radioactive material shipped offsite to a processor does not have to meet solidification or dewatering criteria prior to shipment to the vendor. There were no substantive changes to APA-ZZ-01011, "Process Control Program" during the reporting period.
