Callaway Energy Center 2015 Annual Radioactive Effluent Release Report 1

Abstract The Annual Radioactive Effluent Release Report covers the operation of the Callaway Energy Center during the year 2015. The report includes a summary of the quantities of radioactive liquid and gaseous effluents and solid waste released from the unit. The report also includes an annual summary of hourly meteorological data collected during the year and an assessment of radiation dose to the Member of the Public from liquid and gaseous effluents.

Callaway Energy Center

Annual Radioactive Efluent Release Report Facility Operating License NPF-30 Docket Numbers 50-483 and 72-1045

. 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 10 CFR 72.44(d)(3), Callaway Energy Center Technical Specification 5.6.3, and HI-STORM UMAX Certificate of Compliance Section 5.1.c. This report is for the period January 1, 2015 to December 31, 2015.

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 Radioactive 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 to ULNRC06300 Page 2 of 37

Callaway Energy Center 2015 Annual Radioactive Effluent Release Report 2

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 14C released in gaseous effluents was calculated as described in EPRI Technical Report 10211061.

There were no radioactive effluents from the Independent Spent Fuel Storage Installation (ISFSI).

The HI-STORM UMAX Canister Storage System does not create any radioactive materials or have any radioactive waste treatment systems. Specification 3.1.1, "Multi-Purpose Canister (MPC)",

provides assurance that there are no radioactive effluents from the ISFSI.2

!. 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 2015 Annual Radioactive Effluent Release Report 3

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 D/Q, as described in the ODCM. The organ dose does not include the dose from 14C, which is listed separately.

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 14C (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), 10 CFR 72.104, and 40 CFR 190.

7. 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 Inoperability There were no effluent radiation monitors out of service for periods in excess of the Limiting Condition for Operation and associated Action statements. to ULNRC06300 Page 4 of 37

6.6 Offsite Dose Calculation Manual Changes APA-ZZ-01003 Callaway Offsite Dose Calculation Manual Changes Rev. No.

20 Date April, 2015 Revised Table 10 to implement the recalculated dispersion parameters using 2009-2013 meteorology. Deleted Table 11 as described in HPCI1503. Added HPCI1502, HPCI1503, HPCI1504, & HPCI1505 as references. Deleted reference to calculation ZZ-67. Added Independent Spent Fuel Storage Installation (ISFSI) to Appendix A, Figure 1. Conforming changes were made within the text of the document to implement the revisions noted above. Revised Section 6 to describe the recalculation of the long-term dispersion parameters. (CAR 201500947) Deleted Section 8; the following sections were renumbered accordingly.

Rev. No.

21 Date May, 2015 Revised Table 10 to correct typographical errors in the dispersion parameters for the Site Boundary and Nearest Resident. (CAR 201502908)

A copy of the ODCM rev. 20 and rev. 21 is provided under separate cover as ULNRC-6290. Each change in rev. 20 and rev. 21 is identified by markings in the margin of the affected pages, clearly indicating the area of the page that was changed, and the date, i.e., month and year, the change was implemented is shown at the bottom of each page in each document.

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

6.8 Corrections to Previous Reports There are two typos in the 2014 Annual Radioactive Effluent Release Report (ARERR). In Appendix D, the sample date for MW-032 and MW-033 are given as 2015. The correct sample date is 2014. The corrected pages are attached in their entirety in Appendix C to this report. The area of change is marked by a vertical line in the left margin.

6.9 Other Information Related to Radioactive Effluents Meteorological Joint Frequency Tables for the monitoring period are attached as Appendix B.
