SUMMARY

ANNUAL REPORT, SUPPLEMENTAL INFORMATION Facility: Dresden Nuclear Power Station Units 1,2,3 Licensee: Exelon Nuclear

3. Average Energy The ODCM limits dose rates at or beyond the site boundary due to the release of noble gases to less than or equal to 500 mrem per year to the total body and less than or equal to 3,000 mrem per year to the skin, and average energy is not used to determine dose to the public. Compliance with these limits is demonstrated based on dose calculations using measured isotopic concentrations of effluent streams and not based on gross count rate measuring systems.

Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21, "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," are not applicable.

4. Measurement and Approximations of Total Radioactivity

a. Fission and Activation Gases:

b. Iodines:

c. Particulates:

d. Tritium:

e. Gross Alpha The 2/3 Chimney, 2/3 Reactor Building Vent, and Chemical Cleaning Building effluents are continuously sampled for iodines and particulates. These samples are changed weekly and analyzed by gamma spectroscopy.

The particulate filters are composited and sent to a vendor for gross alpha, Sr-89, Sr-90, and Fe-55 analysis.

Noble gas grab samples of the 2/3 Chimney and 2/3 Reactor Building Vent are obtained weekly and analyzed by gamma spectroscopy. Contributing streams of the 2/3 Chimney and 2/3 Reactor Building Vent are also sampled and analyzed by gamma spectroscopy. Tritium samples of the 2/3 Chimney and 2/3 Reactor Building Vent are obtained monthly and analyzed by liquid scintillation.

For the 2/3 Chimney and 2/3 Reactor Building Vent effluents, measured flow at the release points is used to calculate the curies released. Chemical Cleaning Building effluents, the design basis flows are used to calculate curies released.

f. Carbon- 14:

Carbon-14 activity released is estimated using Electric Power Research Institute Technical Report 1021106 Boiling Water Reactor proxy values (5.1 Ci per GWth year, Section 3.7) and the rated thermal capacity maintained for the entire calendar year. Resultant dose is calculated using approved methodologies.

g. Liquid Effluents:

The river discharge tank is analyzed for gamma-emitting nuclides by gamma spectroscopy and for tritium by liquid scintillation prior to discharge. A representative portion of this sample is saved and composited with other discharges that occur during the calendar month. The composite is sent to a vendor for analyses of gross alpha, Sr-89, Sr-90, and Fe-55. The tank volumes and activities are used to calculate the diluted activity released at the discharge point from batch discharges.

Containment Cooling Service Water (CCSW) is sampled from the Low Pressure Coolant Injection (LPCI) heat exchangers monthly and analyzed for gamma-emitting nuclides by gamma spectroscopy. These samples are composited quarterly and analyzed for tritium, gross alpha, Sr-89, Sr-90, and Fe-55. Batch release volume is based on LPCI heat exchanger volume.

SUMMARY

ANNUAL REPORT, SUPPLEMENTAL INFORMATION Facility: Dresden Nuclear Power Station Units 12,3 Licensee: Exelon Nuclear concentrations measured during each calendar quarter of 2013 was used to calculate the released activity for each month. The total activity released is based on an estimated typical discharge flow of 10 gallons per minute.

Tritium was detected in the storm sewers in three of the four quarters. An estimated 3.33E-03 Ci of tritium was released to the environment during 2013.

b. 1 The Unit 1 Main Turbine Floor is used as an area to work on contaminated equipment. The ventilation system is no longer operational and the floor is at ambient pressure with the outside environment. With radiological work activities being performed on the Unit 1 Main Turbine Floor, the potential exists for airborne activity to be released to the environment through various points. Based on the work normally performed in this area, an estimated 3.60E-05 Ci of Cs-137 was released from this area during 2013.

b.2 The Chemistry Laboratory Ventilation System exhausts directly into the environment and is not monitored.

Based on an evaluation of activities performed in the area, the estimated activity released to the environment from the laboratory in 2013 is 8.93E-05 Ci of noble gases and 9.02E-07 Ci of iodines and particulates.

b.3 The Unit 2/3 Heating Steam System has been contaminated in the past. The system continues to contain low-level tritium contamination. During normal operation, the condensate is converted to steam, a portion of which gets vented to the atmosphere. An estimated 1.46E-05 Ci of activity was released to the environment during 2013.

b.4 The Unit 2 Isolation Condenser, once per five year heat removal capacity test was conducted on November 5, 2013. Low level tritium was detected and 1.89E-04 Ci were released during the test.

9. Errata:

Corrections to the 2011 Annual Radioactive Effluent Release Report have been made and are included at the end of this report.

DRESDEN NUCLEAR POWER STATION 2013 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT RADIOLOGICAL IMPACT ON MAN DOCKET NUMBERS: 50-010/50-237/50-249

1. Liquid Dose to a Member of the Public for 2013 Total Body: 1.22E-08 mrem Organ: 1.22E-08 mrem

2. Gaseous Dose to a Member of the Public for 2013 Total Body: 2.19E-02 mrem Skin: 5.35E-03 mrem Organ (Particulate/Iodine): 9.22E-02 mrem

3. Direct Radiation Dose to a Member of the Public for 2013 Total Body: 8.76E+00 mrem which is 35.1 % of 40CFR190 Limit of 25 mrem/year (Whole Body and Organ).

Thyroid dose: 2.30e-2 mrem which is 0.03 % of 40CFRI90 Limit (75 mrem).

4. Total Body Doses to the Population and Average Doses to Individuals in the Population from All Receiving-Water-Related-Pathways: Not applicable for DNPS. No downstream drinking water pathway exist within the specified distance of 10 kilometers (6.2miles).

5. Total Body Doses to the Population and Average Doses to Individuals in the Population from Gaseous Effluents to a Distance of 50 Miles: Not applicable for DNPS.

6. Doses From Liquid and Gaseous Effluent to Members of the Public Due to Their Activities Inside the Site Boundary for the Report Period: Not applicable for DNPS. Any member of the public that is onsite for a significant period will be issued a Optical Stimulated Luminescent Dosimeter (OSLD).

7. Liquid and Gaseous Effluent Radiation Monitors and Instrumentation Unavailability for the Period Beyond the Requirements of the ODCM. Including Sampling Deviation:

On August 19, 2013 at 08:48, ODCM 12.2.2 conditions A and H were entered because the Unit 2/3 Chimney SPING Mid and High Range noble gas monitors were inoperable for scheduled planned maintenance. The Mid and High Range noble gas channels remained inoperable until Semptember 11, 2013 at 09:24. Alternate monitoring in accordance with the ODCM requirements was implemented. This alternate monitoring provided compensation for the inoperable Mid and High Range noble gas channels. The Low Range noble gas channels remained on scale at all times during the alternate monitoring period. This event was reported to the NRC on September 23, 2013 as required when the channels are inoperable greater than 21 days.

8. 40CFR 190 / 10CFR72 Compliance The General Electric Hitachi Nuclear Energy Morris Operation (GE-Hitachi Morris Operation) facility is physically located near Dresden Station and, in addition to evolutions performed at Dresden station, is considered in the evaluation of the uranium fuel cycle on members of the public in the general environment for 40CFR 190 compliance.

Dresden decommissioning activities (Unit 1) and operations (Units 2 and 3) resulted in a maximum 9.22E-02 mrem organ dose and 8.78E+00 mrem total body dose. Radiological Environmental Monitoring Program (REMP) direct radiation monitoring at or near the site boundary demonstrates that total body dose calculations are conservative.

No effluents were released from the Dresden Independent Spent Fuel Storage Installations (ISFSIs) during 2013. REMP direct radiation monitoring at or near the site boundary demonstrates that the ISFSIs do not result in measurable dose to the public.

Per the 2013 GE-Hitachi Morris Operation 10CFR72.44(d)(3) report, maximum dose at their site boundary from direct radiation exposure was 4.66E-01 mrem and maximum organ dose was 1.47E-02 mrem for 2013.

DRESDEN NUCLEAR POWER STATION 2011 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT January through December 2011 EFFLUENT AND WASTE DISPOSAL

SUMMARY

ANNUAL REPORT 2011 RADIOLOGICAL IMPACT ON MAN DOCKET NUMBERS: 50-010/50-237/50-249 Liquid Dose to a Member of the Public for 2011 Total Body: 1.32E-06 mrem Organ: 2.08E-06 mrem

2. Gaseous Dose to a Member of the Public for 2011 Total Body: 2.13E-02 mrem Skin: 3.80E-03 mrem Organ (Particulate/Iodine): 9.18E-02 mrem

3. Direct Radiation Dose to a Member of the Public for 2011 Total Body: 8.36E+00 mrem This is 33.4 % of 40CFRI90 Limit of 25 mrem/year (Whole Body and Organ). Thyroid dose is 0.10 % of 40CFR190 Limit (75 mrem).

4. Total Body Doses to the Population and Average Doses to Individuals in the Population from All Receiving-Water-Related-Pathways: Not applicable for DNPS. No downstream drinking water pathway exist within the specified distance of 10 kilometers (6.2miles).

5. Total Body Doses to the Population and Average Doses to Individuals in the Population from Gaseous Effluents to a Distance of 50 Miles: Not applicable for DNPS.

6. Doses From Liquid and Gaseous Effluent to Members of the Public Due to Their Activities Inside the Site Boundary for the Report Period: Not applicable for DNPS. Any member of the public that is onsite for a significant period will be issued a Thermo Luminescent Dosimeter (TLD).

7. Liquid and Gaseous Effluent Radiation Monitors and Instrumentation Unavailability for the Period Beyond the Requirements of the ODCM, Including Sampling Deviation:

No ODCM required monitors were unavailable beyond requirements of the ODCM in 2011.

8. 40CFR 190 / 10CFR72 Compliance The General Electric Hitachi Nuclear Energy Morris Operation (GE-Hitachi Morris Operation) facility is physically located near Dresden Station and, in addition to evolutions performed at Dresden station, is considered in the evaluation of the uranium fuel cycle on members of the public in the general environment for 40CFR 190 compliance.

Dresden decommissioning activities (Unit 1) and operations (Units 2 and 3) resulted in a maximum 9.18E-02 mrem organ dose and 8.38E+00 mrem total body dose. Radiological Environmental Monitoring Program (REMP) direct radiation monitoring at or near the site boundary demonstrates that total body dose calculations are conservative.

No effluents were released from the Dresden Independent Spent Fuel Storage Installations (ISFSIs) during 2011. REMP direct radiation monitoring at or near the site boundary demonstrates that the ISFSIs do not result in measurable dose to the public.

Per the 2011 GE-Hitachi Morris Operation 10CFR72.44(d)(3) report, maximum dose at their site boundary from direct radiation exposure was 1.07E+00 mrem and maximum organ dose was 1.35E-02 mrem for 2011.

Maximum total body dose from Dresden and GE-Hitachi Morris Operation activities is 9.45E+00 mrem during 2011, which is 37.8 % of the 40CFR190 limit of 25 mrem.

Maximum organ dose from Dresden and GE-Hitachi Morris Operation activities is 1.05E-01 mrem during 2011.

This is 0.42 % of the 40CFRI90 limit of 25 mrem to any organ. The thyroid dose is 0.14 % of the 40CFRI90 limit of 75 mrem.
