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 (ODCMS) limits.
There were two (2) unplanned releases of liquid radioactive material. One release was from Residual Heat Removal (RHR) heat exchanger and the other is from groundwater tritium contamination ('tritium plume'). These releases were far below regulatory limits.
There was one (1) unplanned release of gaseous radioactive material during the Unit 2 20th Refueling Outage on October 24, 2014. This was due to thermal convective currents in the Reactor Building while hatches were open to support Unit 2 outage work activities. Details of this release are included in this report. This release was far below regulatory limits.
The maximum calculated organ dose (bone) from iodines (1-131, 1-133 and 1-135), tritium (H-3),
carbon-14 (C-14) and particulates to any individual due to gaseous effluents was 5.49E-01 mrem, which was approximately 1.83E+00% of the annual limit. The maximum calculated air dose in the UNRESTRICTED Area due to noble gas effluents was 2.33E-01 mrad (gamma) and 1.60E-01 mrad (beta), which was 1.16E+00% and 3.99E-01%, respectively, of the annual limits.
There were no gaseous or liquid radioactive releases from the decommissioned Unit 1 in SAFSTOR1 status. All radioactive water that collected in spaces inside was removed and was transferred from the Unit 1 Radioactive Material License to the Unit 2 and 3 Operating License to be processed through the normal radioactive waste processing systems.
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 2014.

The maximum permissible dose rates for gaseous releases are defined in ODCMS 3.8.C.l.a and 3.8.C.l.b.
The Effluent Concentrations Limits (ECL) specified in 10 CFR 20, Appendix B, Table 2, Column 2 and multiplied by 10, for identified nuclides, are used to calculate permissible release rates and concentrations for liquid release per ODCMS 3.8.B.1.
The total activity concentration for all dissolved or entrained noble gases is limited to < 2E-04 p.Ci/ mL (ODCMS 3.8.B.1.b).
Average Energy The PBAPS 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, Revision 1, "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 PBAPS.

Grab samples are taken and analyzed weekly to determine the isotopic mixture of noble gas activity released for the week. 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 were analyzed to report noble gas effluent activities. When no activity was identified in the grab isotopic analysis, the entire release must be assumed to be the radionuclide most-limiting dose factors for the release pathway (i.e. krypton-88 (Kr-88) for all ground-level releases, Kr-88 for elevated gamma dose and Kr-87 for elevated beta dose; see ODCM IV.B and NUREG-0133 2 ).
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.
lodines The method used is the Canberra GenieTM System with a charcoal cartridge. Iodine activity was continuously sampled and analyzed in accordance with ODCMS Table 4.8.C.1.
Particulates The method used is the Canberra GenieTM System with a particulate filter (47 mm diameter).
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 analyses of strontium-89 (Sr-89), strontium-90 (Sr-90) and gross alpha.
Carbon-14 The amount of C-14 released was estimated using the guidance from the Electric Power Research Institute (EPRI) Technical Report 1021106, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents". The C-14 was released primarily through the stack (9.7E+01%) with a small amount (3.OOE+00%) through the plant vents. The C-14 in liquid effluents is not a significant dose pathway, as determined from studies. The resulting annual dose to the maximum conservative receptor is 5.49E-01 mrem, with the limiting receptor as the child bone.
Liquid Effluents Gamma isotopic activity concentrations are determined on each batch of liquid effluent prior to release using the Canberra GenieTM System in accordance with ODCMS Table 4.8.B.1.

The actual flow rate of Circulation Water (the water that is circulated within the plant for cooling) is determined for each liquid effluent release because this Circulation Water provides dilution and therefore reduces the projected dose.
Abnormal or Unplanned Releases
'Abnormal' releases are those releases that are not defined as 'normal' releases in the Licensee's ODCM. While attempts are made to ensure radioactivity is not released offsite without processing, monitoring of systems with a potential for release is continuously performed. Source terms used for dose calculations utilize direct sampling and the maximum concentrations of nuclides to ensure that the most conservative and bounding estimates are used. Methodologies used calculate conservative dose uses conservative mathematical models to describe intake and exposure pathways. Therefore, reported doses for these abnormal releases are calculated conservatively.
Liquid Releases GroundwaterTritimn Plume During 2014, 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 flow into the Plant intake and eventually flow into the normal Discharge Canal. Details of this program can be found in the Peach Bottom AREOR as an appendix. No other nuclides were detected from monitoring wells.
Analysis of Release It was assumed from the maximum flow rates measured 5 that ground water flowed to the discharge canal at a steady rate of 317 gpm, carrying with it some of the tritium underneath the plant. The conservative maximum dose for the entire year from this continuous release is 6 calculated to be 3.91E-05 mrem (whole-body) and 3.91E-05 mrem (any organ, except bone which is 0.OOE+O0 mrem) 7. This dose contribution projection is well below the limit specified in the ODCM.
The tritium concentration decreased over the period demonstrating that the RGPP at Peach Bottom is effective at locating and correcting leaks. Surveillance of this program is ongoing.

6 Tritium dose factor for bone is 0.OOE+00; therefore no hypothetical dose is calculated.
7These doses are identical because the dose factors are identical for the same nuclide and pathway.

The dose model assumes that contaminated water leaks from the heat exchanger, regardless of operating pressure to ensure conservatism in calculated dose. As an additional precaution, installed radiation monitoring instrumentation can indicate an inadvertent release of radioactive material should the heat exchanger develop a large leak with a large amount of radioactivity.
Analysis of Release It was assumed that the water released to the discharge canal for all of 2014 contributed a conservative maximum 3.81E-04 mrem Total Body dose (receptor child), and a conservative maximum 7.OOE-04 mrem for the conservative maximum organ, child 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 analyses 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.
Gaseous Releases Unit 2 Equipment Ground Hatch Opening Maintenance hatches were opened to permit equipment to be moved in and out of the plant duing the twentieth refueling outage on Unit 2 (P2R20). Because the inside air of the plant can remain warmer than the colder outside air, an open hatch would exhibit a small convective current of air. An open ground hatch on October 24, 2014 was noticed by Radiation Protection personnel conducting periodic surveillance of open boundaries to have a slight current of air.
This was immediately reported and particulate air samples were analyzed for radioactivity. The maximum concentration of Co-60 was found to be 1.69E-11 ViCi/cc and positive air flow of 2.OOE-01 m/s was estimated for a period of 4.95E+02 minutes. The conservative dose rate (1.40E-05 mrem/ year) and conservative dose (3.52E-07 mrem Ground-Plane) calculated for this release was well-below the limits in the ODCM. No other nuclides were identified.
Changes to the ODCM There were no changes to the ODCM in 2014.

Samples were analyzed with techniques that achieved the required Lower Limits of Detection (LLD) as specified in ODCMS Table 4.8.B.1, "Radioactive Liquid Waste Sampling and Analysis" (for liquids) or ODCMS Table 4.8.C.1, "Radioactive Gaseous Waste Sampling and Analysis from Main Stack and Vent Stack" (for gases). In all cases, the LLD requirements were satisfied.
Sampling and Analysis Deviations With the Unit 2 Service Water radiation monitor out of service on 1 November 2014, compensatory sampling by grab sample was required to be performed in accordance with the ODCMS 3.8.B.3, Compensatory Action D. However, a sample was not analyzed within the required completion time (approximately six minutes late). The Licensee entered this deviation into its Corrective Action Program.
Violations There were no effluent release violations for the 2014 reporting period.
Dose Assessmient Introduction A dose assessment for PBAPS was conducted from measured radioactive effluent source terms and environmental data to verify that PBAPS continues to demonstrate compliance with the limits as well as the requirement of maintaining the doses "as low as is reasonably achievable" as stated in 10 CFR 50, Appendix 1.8 The radioactive source term used for both liquids and gases are the current radioactive source terms given in this report, Attachment 2, "Effluent Summary".
Liquid Dose Assessment Hydrologic Conditionsand Receptor Locationsof Interest PBAPS is located on the Conowingo Pond formed in the Susquehanna River by the Conowingo Dam. For 2014, the average river flow was measured 9 to be approximately 3.52E+04 ft 3/ s.
Of these three separate flow regimes that were used in the original Appendix I submittal, the most-limiting of them (<1.50E+04 ft 3/ s) was used to calculate a dose assessment for this report because this would provide a bounding extreme for all PBAPS liquid effluents. Therefore, although the actual average stream flow for the year was more than double the limiting case, this report will provide an upper limit for the most-limiting dose.

Liquid Effluent Dose Assessment Conclusion The calculated limiting Total Body dose was 5.47E-06 mrem and the limiting organ dose was 8.71E-06 mrem for the limiting receptor of adult GI-LLI (gastro-intestinal tract, lower-large intestine).
Therefore, PBAPS liquid radioactive effluent controls continue to demonstrate compliance with 10 CFR 50, Appendix I objectives for the purposes of keeping doses to members of the public "as low as is reasonably achievable". These limiting or maximum calculated doses are a small fraction of the limits in Appendix I.

The noble gas limiting air doses were 3.55E-01 mrad (gamma) and 6.84E-02 mrad (beta). Noble gas plume conservative dose was 2.40E-01 mrem for the year (Total Body) and 3.31E-01 mrem (Skin Dose) for the year.
All doses are projected to be much less than the limits, as expected. Again, these dose models incorporate several factors of conservatism including a source term that, by procedure, will use the most dose-limiting noble gas nuclide when no fission gas can be identified by grab sample but activity is detected from the effluent radiaition monitor.
Exelon Nuclear uses a more-detailed C-14 dose projection from the Electric Power Research Institute, Technical Report 1021106. Details for the assumptions used in this calculation may be found there.16 Therefore, PBAPS gaseous radioactive effluent controls continue to demonstrate compliance with 10 CFR 50, Appendix I objectives for the purposes of keeping doses to members of the public "as low as is reasonably achievable". These limiting or maximum calculated doses are a small fraction of the limits in Appendix I.
16 For PBAPS uses specific Boiling Water Reactor assumptions because the fraction of C-14 that is in the CO form 2
will vary based on general plant design. This is important because the major dose pathway is through photosynthesis and, therefore, only the oxide form is relevant.

In the 2013 ARERR, it was reported:
With the concentration ranging from 4.16E-06 VCi/ mL to 9.64E-06 iVCi/ ml, the ground water released to the discharge canal was responsible for a hypothetical maximum 1.79E-05 mrem total body dose and critical organ dose (child liver) for the year. This dose contribution projection is well below the limit specified in the ODCM.
This range was not correct. This range maximum should have been 1.07E-05 lmCi/ ml H-3. The conservative dose contribution from the groundwater for the year is 2.81E-05 mrem.
Offisite Laboratory Error Not Reported in 2013 Report An error with the off-site Contract laboratory affecting some Radiological Environmental Monitoring Program (REMP) analysis samples in 2012 and 2013 and their clients were contacted. The vendor was contacted again in 2014 to affirm that no effluent samples (or composite effluent samples) were affected by this earlier analysis issue. Initially, the contract laboratory reported that only REMP samples were affected but the subsequent review indicated that this was not the case and that a revised report for one effluent analysis should have been issued to Peach Bottom but had not been issued in May of 2013 (with the rest of the REMP samples).
No MDCs were affected and all ODCM-required LLDs were met. No nuclides were now
'detected' as a result of the reprocessing of samples. Therefore, this one sample was not materially affected and the accounting of these nuclides was not affected in 2013. No errata to nuclide data or conservative doses are required for the 2013 ARERR.

In 2012, a change to the ODCM was reported which affected the meteorological dispersion factor for ground-releases.
In 2013, errata were issued as an addendum to the 2012 errata concerning the same changes and 2008 data were added because of an extent of condition review that was conducted as part of the identified "particulate and iodine" errors (as described in the 2013 Errata).
These revised calculations were reviewed and are correct. The 2013 errata data should have added a remark indicating that these were addenda to the 2012 errata rather than standalone information.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 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 (PBAPS) Units 2 and 3 for the period January 1, 2014 through December 31, 2014. 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 (ODCMS) limits.

There were two (2) unplanned releases of liquid radioactive material. One release was from Residual Heat Removal (RHR) heat exchanger and the other is from groundwater tritium contamination ('tritium plume'). These releases were far below regulatory limits.

There was one (1) unplanned release of gaseous radioactive material during the Unit 2 20th Refueling Outage on October 24, 2014. This was due to thermal convective currents in the Reactor Building while hatches were open to support Unit 2 outage work activities. Details of this release are included in this report. This release was far below regulatory limits.

The maximum calculated organ dose (bone) from iodines (1-131, 1-133 and 1-135), tritium (H-3),

carbon-14 (C-14) and particulates to any individual due to gaseous effluents was 5.49E-01 mrem, which was approximately 1.83E+00% of the annual limit. The maximum calculated air dose in the UNRESTRICTED Area due to noble gas effluents was 2.33E-01 mrad (gamma) and 1.60E-01 mrad (beta), which was 1.16E+00% and 3.99E-01%, respectively, of the annual limits.

There were no gaseous or liquid radioactive releases from the decommissioned Unit 1 in SAFSTOR1 status. All radioactive water that collected in spaces inside was removed and was transferred from the Unit 1 Radioactive Material License to the Unit 2 and 3 Operating License to be processed through the normal radioactive waste processing systems.

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 2014.

1 SAFSTOR is "[a] method of decommissioning in which a nuclear facility is placed and maintained in a condition that allows the facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use", http://www.nrc.gov/reading-rm/basic-ref/-glossary/safstor.html, accessed 7 APR 2014.

The maximum permissible dose rates for gaseous releases are defined in ODCMS 3.8.C.l.a and 3.8.C.l.b.

The Effluent Concentrations Limits (ECL) specified in 10 CFR 20, Appendix B, Table 2, Column 2 and multiplied by 10, for identified nuclides, are used to calculate permissible release rates and concentrations for liquid release per ODCMS 3.8.B.1.

The total activity concentration for all dissolved or entrained noble gases is limited to < 2E-04 p.Ci/ mL (ODCMS 3.8.B.1.b).

Average Energy The PBAPS 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, Revision 1, "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 PBAPS.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 PSEG Nuclear, LLC Measures and Approximations of Total Radioactivity Fission and Activation Gases The method used for gamma isotopic analysis is the Canberra GenieTM System with a gas Marinelli beaker. Grab samples are taken and analyzed weekly to determine the isotopic mixture of noble gas activity released for the week. 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 were analyzed to report noble gas effluent activities. When no activity was identified in the grab isotopic analysis, the entire release must be assumed to be the radionuclide most-limiting dose factors for the release pathway (i.e. krypton-88 (Kr-88) for all ground-level releases, Kr-88 for elevated gamma dose and Kr-87 for elevated beta dose; see ODCM IV.B and NUREG-0133 2 ).

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.

lodines The method used is the Canberra GenieTM System with a charcoal cartridge. Iodine activity was continuously sampled and analyzed in accordance with ODCMS Table 4.8.C.1.

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

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 analyses of strontium-89 (Sr-89), strontium-90 (Sr-90) and gross alpha.

Carbon-14 The amount of C-14 released was estimated using the guidance from the Electric Power Research Institute (EPRI) Technical Report 1021106, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents". The C-14 was released primarily through the stack (9.7E+01%) with a small amount (3.OOE+00%) through the plant vents. The C-14 in liquid effluents is not a significant dose pathway, as determined from studies. The resulting annual dose to the maximum conservative receptor is 5.49E-01 mrem, with the limiting receptor as the child bone.

Liquid Effluents Gamma isotopic activity concentrations are determined on each batch of liquid effluent prior to release using the Canberra GenieTM System in accordance with ODCMS Table 4.8.B.1.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 PSEG Nuclear, LLC activity of a released batch is determined by multiplying each nuclide's concentration by the total volume discharged.

Composite liquid radwaste samples are analyzed for tritium on-site and submitted to an offsite vendor laboratory for analyses of iron-55 (Fe-55), phosphorus-32 (P-32), Sr-89, Sr-90 and gross alpha.

Decommissioned Unit 1 Liquid Radioactive Waste Processing In 2014, no water from Unit 1 was processed for release.

Estimate of 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.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 PSEG Nuclear, LLC Average Stream Flow The river flow is not used for dose calculations. The actual flow rate of Circulation Water (the water that is circulated within the plant for cooling) is determined for each liquid effluent release because this Circulation Water provides dilution and therefore reduces the projected dose.

Abnormal or Unplanned Releases

'Abnormal' releases are those releases that are not defined as 'normal' releases in the Licensee's ODCM. While attempts are made to ensure radioactivity is not released offsite without processing, monitoring of systems with a potential for release is continuously performed. Source terms used for dose calculations utilize direct sampling and the maximum concentrations of nuclides to ensure that the most conservative and bounding estimates are used. Methodologies used calculate conservative dose uses conservative mathematical models to describe intake and exposure pathways. Therefore, reported doses for these abnormal releases are calculated conservatively.

Liquid Releases GroundwaterTritimn Plume During 2014, 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 flow into the Plant intake and eventually flow into the normal Discharge Canal. Details of this program can be found in the Peach Bottom AREOR as an appendix. No other nuclides were detected from monitoring wells.

Analysis of Release It was assumed from the maximum flow rates measured 5 that ground water flowed to the discharge canal at a steady rate of 317 gpm, carrying with it some of the tritium underneath the plant. The conservative maximum dose for the entire year from this continuous release is 6 calculated to be 3.91E-05 mrem (whole-body) and 3.91E-05 mrem (any organ, except bone which is 0.OOE+O0 mrem) 7. This dose contribution projection is well below the limit specified in the ODCM.

The tritium concentration decreased over the period demonstrating that the RGPP at Peach Bottom is effective at locating and correcting leaks. Surveillance of this program is ongoing.

s "Estimated Mass Flux Of Tritiated Groundwater To The Conowingo Reservoir And Rock Run Creek, Peach Bottom Atomic Power Station, Delta, Pennsylvania", November 2011, Conestoga-Rovers &Associates.

6 Tritium dose factor for bone is 0.OOE+00; therefore no hypothetical dose is calculated.

7These doses are identical because the dose factors are identical for the same nuclide and pathway.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, ILC Unit 2 and 3 PSEG Nuclear, LLC Heat ExchangerLeakage Throughout the 2014 calendar year, small leaks were discovered in three of the Unit 2 and Unit 3 Residual Heat Removal (RHR) Heat Exchangers, which are designed to circulate water to remove heat from their respective reactor units when necessary. The dose model assumes that contaminated water leaks from the heat exchanger, regardless of operating pressure to ensure conservatism in calculated dose. As an additional precaution, installed radiation monitoring instrumentation can indicate an inadvertent release of radioactive material should the heat exchanger develop a large leak with a large amount of radioactivity.

Analysis of Release It was assumed that the water released to the discharge canal for all of 2014 contributed a conservative maximum 3.81E-04 mrem Total Body dose (receptor child), and a conservative maximum 7.OOE-04 mrem for the conservative maximum organ, child 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 analyses 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.

Gaseous Releases Unit 2 Equipment Ground Hatch Opening Maintenance hatches were opened to permit equipment to be moved in and out of the plant duing the twentieth refueling outage on Unit 2 (P2R20). Because the inside air of the plant can remain warmer than the colder outside air, an open hatch would exhibit a small convective current of air. An open ground hatch on October 24, 2014 was noticed by Radiation Protection personnel conducting periodic surveillance of open boundaries to have a slight current of air.

This was immediately reported and particulate air samples were analyzed for radioactivity. The maximum concentration of Co-60 was found to be 1.69E-11 ViCi/cc and positive air flow of 2.OOE-01 m/s was estimated for a period of 4.95E+02 minutes. The conservative dose rate (1.40E-05 mrem/ year) and conservative dose (3.52E-07 mrem Ground-Plane) calculated for this release was well-below the limits in the ODCM. No other nuclides were identified.

Changes to the ODCM There were no changes to the ODCM in 2014.

14

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 PSEG Nuclear, LLC Minimum Detectable Concentrations If a radionuclide was not detected, "<LLD" was reported as the activity. Samples were analyzed with techniques that achieved the required Lower Limits of Detection (LLD) as specified in ODCMS Table 4.8.B.1, "Radioactive Liquid Waste Sampling and Analysis" (for liquids) or ODCMS Table 4.8.C.1, "Radioactive Gaseous Waste Sampling and Analysis from Main Stack and Vent Stack" (for gases). In all cases, the LLD requirements were satisfied.

Sampling and Analysis Deviations With the Unit 2 Service Water radiation monitor out of service on 1 November 2014, compensatory sampling by grab sample was required to be performed in accordance with the ODCMS 3.8.B.3, Compensatory Action D. However, a sample was not analyzed within the required completion time (approximately six minutes late). The Licensee entered this deviation into its Corrective Action Program.

Violations There were no effluent release violations for the 2014 reporting period.

Dose Assessmient Introduction A dose assessment for PBAPS was conducted from measured radioactive effluent source terms and environmental data to verify that PBAPS continues to demonstrate compliance with the limits as well as the requirement of maintaining the doses "as low as is reasonably achievable" as stated in 10 CFR 50, Appendix 1.8 The radioactive source term used for both liquids and gases are the current radioactive source terms given in this report, Attachment 2, "Effluent Summary".

Liquid Dose Assessment Hydrologic Conditionsand Receptor Locationsof Interest PBAPS is located on the Conowingo Pond formed in the Susquehanna River by the Conowingo Dam. For 2014, the average river flow was measured 9 to be approximately 3.52E+04 ft 3/ s.

Of these three separate flow regimes that were used in the original Appendix I submittal, the most-limiting of them (<1.50E+04 ft 3/ s) was used to calculate a dose assessment for this report because this would provide a bounding extreme for all PBAPS liquid effluents. Therefore, although the actual average stream flow for the year was more than double the limiting case, this report will provide an upper limit for the most-limiting dose.

Liquid Effluent Dose Assessment Conclusion The calculated limiting Total Body dose was 5.47E-06 mrem and the limiting organ dose was 8.71E-06 mrem for the limiting receptor of adult GI-LLI (gastro-intestinal tract, lower-large intestine).

Therefore, PBAPS liquid radioactive effluent controls continue to demonstrate compliance with 10 CFR 50, Appendix I objectives for the purposes of keeping doses to members of the public "as low as is reasonably achievable". These limiting or maximum calculated doses are a small fraction of the limits in Appendix I.

Noble gas plume conservative dose was 2.40E-01 mrem for the year (Total Body) and 3.31E-01 mrem (Skin Dose) for the year.

All doses are projected to be much less than the limits, as expected. Again, these dose models incorporate several factors of conservatism including a source term that, by procedure, will use the most dose-limiting noble gas nuclide when no fission gas can be identified by grab sample but activity is detected from the effluent radiaition monitor.

Exelon Nuclear uses a more-detailed C-14 dose projection from the Electric Power Research Institute, Technical Report 1021106. Details for the assumptions used in this calculation may be found there.16 Therefore, PBAPS gaseous radioactive effluent controls continue to demonstrate compliance with 10 CFR 50, Appendix I objectives for the purposes of keeping doses to members of the public "as low as is reasonably achievable". These limiting or maximum calculated doses are a small fraction of the limits in Appendix I.

16 For PBAPS uses specific Boiling Water Reactor assumptions because the fraction of C-14 that is in the CO form 2

will vary based on general plant design. This is important because the major dose pathway is through photosynthesis and, therefore, only the oxide form is relevant.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 PSEG Nuclear, LLC Appendix A: Errata Data Section 86

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LIC Unit 2 and 3 PSEG Nuclear, LLC Corrected 2013 Maximum Radioactive Groundwater Protection Program (RGPP) values.

In the 2013 ARERR, it was reported:

With the concentration ranging from 4.16E-06 VCi/ mL to 9.64E-06 iVCi/ ml, the ground water released to the discharge canal was responsible for a hypothetical maximum 1.79E-05 mrem total body dose and critical organ dose (child liver) for the year. This dose contribution projection is well below the limit specified in the ODCM.

This range was not correct. This range maximum should have been 1.07E-05 lmCi/ ml H-3. The conservative dose contribution from the groundwater for the year is 2.81E-05 mrem.

Offisite Laboratory Error Not Reported in 2013 Report An error with the off-site Contract laboratory affecting some Radiological Environmental Monitoring Program (REMP) analysis samples in 2012 and 2013 and their clients were contacted. The vendor was contacted again in 2014 to affirm that no effluent samples (or composite effluent samples) were affected by this earlier analysis issue. Initially, the contract laboratory reported that only REMP samples were affected but the subsequent review indicated that this was not the case and that a revised report for one effluent analysis should have been issued to Peach Bottom but had not been issued in May of 2013 (with the rest of the REMP samples).

No MDCs were affected and all ODCM-required LLDs were met. No nuclides were now

'detected' as a result of the reprocessing of samples. Therefore, this one sample was not materially affected and the accounting of these nuclides was not affected in 2013. No errata to nuclide data or conservative doses are required for the 2013 ARERR.

Peach Bottom Atomic Power Station Licensee: Exelon Generation Company, LLC Unit 2 and 3 PSEG Nuclear, LLC Clarification to Errata in 2013 ARERR regarding corrected noble gas conservative dose calculations.

In 2012, a change to the ODCM was reported which affected the meteorological dispersion factor for ground-releases.

In 2013, errata were issued as an addendum to the 2012 errata concerning the same changes and 2008 data were added because of an extent of condition review that was conducted as part of the identified "particulate and iodine" errors (as described in the 2013 Errata).

These revised calculations were reviewed and are correct. The 2013 errata data should have added a remark indicating that these were addenda to the 2012 errata rather than standalone information.
