Facility: Peach Bottom Units 2 & 3 Licensee: Exelon Generation Company, LLC PSEG Nuclear, LLC INTRODUCTION In accordance with the Reporting Requirements of Technical Specification 5.6.3 applicable during the reporting period, this report summarizes the Effluent Release Data for Peach Bottom Atomic Power Station Units 2 and 3 for the period January 1, 2009 through December 31, 2009. The notations E+ and E-are used to denote positive and negative exponents to the base 10, respectively.

The release of radioactive materials during the reporting period was within the Offsite Dose Calculation Manual Specification limits.

There were four unplanned releases of liquid radioactive material. Two releases were from RHR heat exchangers, one was from a groundwater tritium plume and one was from the U2 Yard Drain Sump.

There were no gaseous or liquid radioactive releases from the Independent Spent Fuel Storage Installation, NRC Docket No. 72-29 (ISFSI).

There were no changes made to RW-AA-100 "Process Control Program for Radioactive Waste" in 2009.

There were no changes needed for the 2008 Effluent Report. Therefore, Appendix A is intentionally left blank.

There were changes made to the ODCM during the 2009 reporting period. A copy of the revised ODCM Revision 13 is attached with this document and included as Appendix B. Each change is identified by markings in the margin of affected pages, indicating the area of the page that was change and the date (month/year) the change was implemented.

Exelon common procedures, which provide consistent expectations and standards for Radioactive Effluents Controls Program, were used to generate this report. They are:

2. Maximum Permissible Concentrations:

Gaseous dose rates rather than effluent concentrations are used to calculate permissible release rates for gaseous releases. The maximum permissible dose rates for gaseous releases are defined in ODCMS 3.8.C.la. and 3.8.C.1.b.

The Effluent Concentrations Limits (ECL) specified in 10 CFR 20, Appendix B, Table 2, Column 2 times 10, for identified nuclides, are used to calculate permissible release rates and concentrations for liquid release per Peach Bottom Offsite Dose Calculation Manual Specification 3.8.B.1.

The total activity concentration for all dissolved or entrained gases is limited to

< 2E-04 liCi/ml.

3. Average Energy:

The Peach Bottom ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin. Therefore, the average beta and gamma energies of the radionuclide mixture in releases of fission and activation gases as described in Regulatory Guide 1.21, "Measuring, Evaluation, 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 to Peach Bottom.

4. Measurements and Approximations of Total Radioactivity:

A. Fission and Activation Gases:

The method used for Gamma Isotopic Analysis is the Canberra Genie System with a gas Marinelli beaker. Grab samples are taken and analyzed at least monthly to determine the isotopic mixture of noble gas activity released for the month. Airborne effluent gaseous activity was continuously monitored and recorded in accordance with ODCMS Table 4.8.C.1. The data from the noble gas radiation monitor was analyzed to report noble gas effluent activities. When no activity was found in the grab isotopic analysis, the isotopic mixture was assumed to be that specified in ODCM IV.B. The activity released is listed as Unidentified in the Attachment 2 Tables. If activity was found in the grab isotopic analysis, the isotopic mixture for the Noble Gas Monitor was determined from that isotopic mixture.

Facility: Peach Bottom Units 2 & 3 Licensee: Exelon Generation Company, LLC PSEG Nuclear, LLC B. lodines:

The method used is the Canberra Genie System with a charcoal cartridge.

Iodine activity was continuously sampled and analyzed in accordance with ODCMS Table 4.8.C.1.

C. Particulates:

The method used is the Canberra Genie System with a particulate filter (47 mm).

Particulate activity was continuously sampled and analyzed in accordance with ODCM Table 4.8.C.1.

Composite particulate air samples were submitted to an offsite vendor laboratory for analysis of Sr-89, Sr-90 and gross alpha.

D. Liquid Effluents:

Gamma isotopic activity concentrations are determined on each batch of liquid effluent prior to release using the Canberra Genie System in accordance with ODCMS Table 4.8.B.1. The total activity of a released batch is determined by multiplying each nuclide's concentration by the total volume discharged.

Composite liquid radwaste samples counted for tritium and submitted to an offsite vendor laboratory for analysis of Fe-55, P-32, Sr-89, Sr-90 and gross alpha.

About 1,200 gal of water from Peach Bottom Unit 1 that were contaminated with tritium (< 0.03 Ci) were transported to Units 2 & 3 radwaste system and discharged through the laundry drain system as normal discharges. The dose contributions and isotope quantities from the releases were added to this Radioactive Effluent Release Report for the applicable reporting periods.

E. Estimated Total Error Present CY-AA-170-2100, Estimated Errors of Effluent Measurements, provides the methodology to obtain an overall estimate of the error associated with radioactive effluents.

6. Average Stream Flow:

The river flow is not used for dose calculations. The actual discharge of circulating water is used for liquid dose calculations. The circulating water varies from 675,000 gpm in the winter to 1,350,000 gpm in the summer.

7. Abnormal Releases: Four abnormal release sources A. Liquid:
1. Event description - 2C Residual Heat Removal (RHR) to High Pressure Service Water (HPSW) leak On 08/01/2005, routine sampling of the HPSW effluent to the discharge canal detected low-level radioactive contamination. Subsequent investigation determined that a trace amount of condensate stay-full or primary coolant water was leaking through the Unit 2C RHR heat exchanger into the 2A loop of the HPSW system. The 2C RHR continued to be a source of contamination to the beginning of 2009. The leak rate range was 0.0438 GPM to the end of February 2009. The 2C RHR heat exchanger was repaired February 28, 2009 Analysis of Releases It was estimated that the contaminated water released to the discharge canal for all of 2009 was responsible for 9.92E-05 mrem total body dose (Adult), and 1.66E-04 mrem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.

Samples were analyzed for all the parameters of radioactive effluent releases. Composite liquid radwaste samples counted for tritium and submitted to an offsite vendor laboratory for analysis of Fe-55, P-32, Sr-89, Sr-90 and gross alpha. The maximum concentration from several analyses was used to ensure conservative measures of activity released.

The dose contributions and isotope quantities from the releases were added to this Radioactive Effluent Release Report for the applicable reporting periods.

2. Event description - 3A Residual Heat Removal (RHR) to High Pressure Service Water (HPSW) leak On 04/08/2008, routine sampling of the HPSW effluent to the discharge canal detected low-level radioactive contamination. Subsequent investigation 9

Facility: Peach Bottom Units 2 & 3 Licensee: Exelon Generation Company, LLC PSEG Nuclear, LLC determined that a trace amount of condensate stay-full or primary coolant water was leaking through the Unit 3A RHR heat exchanger into the 3A loop of the HPSW system. The 3A RHR continued to be a source of contamination to the end of 2009. The leak rate ranged from was 0.0642 GPM to 0.0529 GPM throughout the year.

Analysis of Releases It was estimated that the contaminated water released to the discharge canal for all of 2009 was responsible 2.82E-03 mrem total body dose (Adult), and 4.57E-03 mrem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.

Samples were analyzed for all the parameters of radioactive effluent releases. Composite liquid radwaste samples counted for tritium and submitted to an offsite vendor laboratory for analysis of Fe-55, P-32, Sr-89, Sr-90 and gross alpha. The dose contributions and isotope quantities from the releases were added to this Radioactive Effluent Release Report for the applicable reporting periods.

3. Event description - Yard Drain Sump During 2009, routine sampling of the Yard Drain Sumps showed no gamma activity but low concentrations of tritium. The tritium was measured to be between 9.24E-07 and 6.08E-06 uCi/ml.

Analysis of Release It was estimated that the contaminated water released to the discharge canal at a rate of 23 gpm. With the tritium concentrations between 9.24E-07 and 6.08E-06 uCi/mL, the water released was responsible for 1.85 mrem total body dose (Child), and 1.85E-06 mrem Critical Organ (Child) dose. This dose contribution was well below the limits specified in the ODCM.

Representative samples were analyzed for gamma activity and tritium.

The dose contributions and isotope quantities from the releases were added to this Radioactive Effluent Release Report for the applicable reporting periods.

4. Event description - Ground Water Plume During 2009, during the sampling and analysis of the Radiological Ground Water Protection Program (RGPP), tritium was measured at several locations around the site. The ground water that has detectable tritium has been determined to discharge into the intake or discharge canal. The highest concentration of tritium measured varied from 3.04E-06 to 7.15E-05 uCi/ml.

Analysis of Releases It was estimated that the ground water flowed to the discharge canal at a rate of 175 gpm. With the concentration ranging from 3.04E-06 to 7.15E-05 uCi/ml, the ground water released to the discharge canal was responsible for 1.08E-04 mrem total body dose (Child), and 1.08E-05 mrem Critical Organ dose (Child). This dose contribution was well below the limits specified in the ODCM.

B. Gaseous:

No abnormal releases.

8. Changes to the ODCM:

A revised copy of the ODCM Revision 13 is attached as Appendix B of this document for the 2009 reporting period. Each change is identified by markings in the margin of affected pages. The major changes to the ODCM were addition of dose factors and update of X/Q values. The details of all the changes are included in Appendix B.
