- 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.1.a 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 pCi/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. If activity was found in the grab isotopic analysis, the isotopic mixture for the Noble Gas Monitor was determined from that isotopic mixture.
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.
6
Facility: Peach Bottom Units 2 & 3 Licensee: Exelon Generation Company, LLC PSEG Nuclear, LLC 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. Tritium in Gaseous Effluents:
Air from the off-gas stack and building vents was passed through two bubblers in series and an aliquot of the water was analyzed using a Liquid Scintillation Counter.
E. Liquid Effluents:
Batch Releases Gamma isotopic activity concentrations are determined on each batch of liqu d 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, Sr-89, Sr-90 and gross alpha.
Abnormal Releases Gamma isotopic activity concentrations are determined by analyzing the source of the water released (Torus or Reactor Building Closed Cooing Water (RBCCW)) using the Canberra Genie System. The maximum concentration from several sample analyses is used for performing release calculations.
Composite liquid torus samples counted for tritium and submitted to an offsite vendor laboratory for analysis of Fe-55, Sr-89, Sr-90 and gross alpha. The RBCCW tritium, Fe-55, Sr-89, Sr-90 and gross alpha were calculated from the reactor water analysis and ratioed using Co-60.

- 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:
A. Liquid:
- 1. Event description - 3A Residual Heat Removal (RHR) to High Pressure Service Water (HPSW) leak On 09/30/2002, routine sampling of the 3A HPSW effluent radiation monitor to the discharge canal detected low-level radioactive contamination.
Subsequent investigation determined that a trace amount (0.012 gpm) 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 leak was repaired on 01/12/2005.
Analysis of Releases It was estimated that the contaminated water released to the discharge canal for all of 2005 was responsible for 1.09E-5 mRem total body dose, and 1.93E-5 mRem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.
Representative samples were analyzed for all the parameters of radioactive effluent releases. 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 - Unit 2 RBCCW to Service Water (SW) leak On 07/15/2005 a leak from the Unit 2 RBCCW system to service water was detected by a decrease in head tank level. The leak was determined to be 0.0043 gpm. The Unit 2 RBCCW was contaminated from a leak in the Unit 2 Reactor Water Cleanup system (RWCU) non-regenerative heat exchanger.
The system was isolated on 09/07/2005 and the leak to SW was stopped.
Analysis of Releases It was estimated that the contaminated water released to the discharge canal for all of 2005 was responsible for 5.57E-6 mRem total body dose, 10
Facility: Peach Bottom Units 2 & 3 Licensee: Exelon Generation Company, LLC PSEG Nuclear, LLC and 7.90E-6 mRem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.
Representative samples were analyzed for all gamma activity of the radioactive effluent releases. Concentration of the beta and alpha emitters were calculated by ratio from reactor coolant samples. 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 - 2B Residual Heat Removal (RHR) to High Pressure Service Water (HPSW) leak On 09/16/2005, the diaphragm on the dp instrument failed causing a leak of 0.24 gpm into the reactor vessel. The 2B RHR heat exchanger was isolated and the 2D RHR heat exchanger was put in service. With the Heat exchanger out of service the RHR leaked into the HPSW. The leak was repaired on 09/21/2005.
Analysis of Releases It was estimated that the contaminated water released to the discharge canal was responsible for 1.76E-4 mRem total body dose, and 2.90E-4 mRem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.
Representative samples were analyzed for all the parameters of radioactive effluent releases. 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 - 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 end of 2005 (0.02 gpm)
Analysis of Releases It was estimated that the contaminated water released to the discharge canal for all of 2005 was responsible for 4.20E-4 mRem total body dose, 11
Facility: Peach Bottom Units 2 & 3 Licensee: Exelon Generation Company, LLC PSEG Nuclear, LLC and 6.87E-4 mRem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.
Representative samples were analyzed for all the parameters of radioactive effluent releases. The dose contributions and isotope quantities from the releases were added to this Radioactive Effluent Release Report for the applicable reporting periods.
- 5. Event description - 2D Residual Heat Removal (RHR) to High Pressure Service Water (HPSW) leak On 10/07/2005, 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 2D RHR heat exchanger into the 2B loop of the HPSW system. The 2D RHR continued to be a source of contamination to the end of 2005 (0.0189 gpm)
Analysis of Releases It was estimated that the contaminated water released to the discharge canal for all of 2005 was responsible for 2.42E-4 mRem total body dose, and 3.95E-3 mRem Critical Organ (Teen Liver) dose. This dose contribution was well below the limits specified in the ODCM.
