INTRODUCTION In accordance with the Reporting Requirements of Technical Specification 5.6.3 applicable during the reporting period, January 1, 2023 through December 31, 2023, this report summarizes the Effluent Release Data for Peach Bottom Atomic Power Station (PBAPS) Units 1, 2 and 3. 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.
In addition to the normal effluent releases from Units 2 and 3, there were three sources of abnormal releases of low-level radioactive material, one from releasing contaminated water and gas from the auxiliary boilers, one from groundwater tritium contamination ('tritium plume'),
and one from leaking Residual Heat Removal (RHR) heat exchangers. These releases were far below regulatory limits.
For all gaseous releases from Units 2 and 3, the maximum calculated organ dose (bone) from iodines (I-131, I-133 and I-135), tritium (H-3), carbon-14 (C-14) and particulates with a > 8-day half-life to any individual was 8.13E-02 mrem, which was approximately 2.71E-01% of the annual limit. The maximum calculated air dose in the unrestricted area due to noble gas effluents was 2.96E-02 mrad (gamma) and 2.02E-02 mrad (beta), which was 1.48E-01% and 5.05E-02%,
respectively, of the annual limits.
In 2023, there were no direct gaseous or liquid releases or discharges from Unit 1 to the environment. Additionally, there were no gaseous or liquid radioactive releases from the Independent Spent Fuel Storage Installation, NRC Docket No. 72-29 (ISFSI).
No changes were made to RW-AA-100 "Process Control Program for Radioactive Waste" in the 2023 reporting period. There was one revision to the ODCM in Appendix A during the 2023 reporting period to update milk sample locations and farm identification nomenclature.

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.
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) 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.
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 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 were analyzed to report noble gas effluent activities. When no activity was identified in the grab isotopic analysis (un-id(s) or un-id(v)), the entire release must be assumed to be the radionuclide with the 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-01331). 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.
Iodines 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), Sr-90, nickel-63 (Ni-63) and gross alpha.

Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 10 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 Main Offgas Stack (9.70E+01%)
with a small amount (3.00E+00%) through the Reactor Building Exhaust Vents. The C-14 in liquid effluents is not a significant dose pathway, as determined from studies.
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 total 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, Ni-63, and gross alpha.
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, which are listed in of this report.
Decommissioned Unit 1 Liquid Radioactive Waste Processing In 2023, there were no direct gaseous or liquid releases or discharges from Unit 1 to the environment. During the reporting period, there were twelve drums of Unit 1 water (488.3 gallons) collected between November 2020 and December 2022 transferred to the Unit 2 and Unit 3 liquid radwaste system for release from the B Laundry Drain Tank. Due to a pump seal failure, the contents were not released and drained from the tank to the floor drain entering the Unit 2 and Unit 3 radwaste system. This water was ultimately processed by the Unit 2 and Unit 3 liquid radwaste system and reused in the plant.

Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 12 Abnormal or Unplanned Releases
'Abnormal' releases are those releases that are not defined as 'normal' releases in the Licensee's ODCM. Systems with a potential for an unplanned release are monitored to ensure if a release were to occur it would be identified and quantified appropriately. 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 calculate conservative doses utilizing conservative mathematical models to describe intake and exposure pathways. Therefore, reported doses for these abnormal releases are calculated conservatively.
Liquid Releases Groundwater Tritium Plume During 2023, sampling and analysis of the Radiological Ground Water Protection Program (RGPP), identified measurable tritium activity at several locations around the site. The ground water that had detectable tritium was 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 Annual Radiological Environmental Operating Report (AREOR) as an appendix. No other nuclides were detected in monitoring wells.
Analysis of Release It was assumed from the maximum flow rates measured that ground water flowed to the discharge canal at a steady rate of 3.44E+02 gpm, carrying with it some of the tritium underneath the plant. The ground water flow rate was updated in December 2022, when the new report was provided4. The conservative maximum dose for the entire year from this continuous release is calculated to be 5.16E-05 mrem to the whole-body and 4.07E-05 mrem to any organ (except bone5 which is 0.00E+00 mrem)6. This dose contribution projection is well below the limit specified in the ODCM.
Contaminated Auxiliary Boiler During 2023, trace amounts of H-3 activity were identified in the auxiliary boiler. Sampling and monitoring of the boiler and deaerator water was performed prior to start up, during operations, and after lay-up to identify any tritium contamination with potential for release.
Liquid releases occurred during blow downs to aid in improving conductivity and turbidity in the operating boiler and for boiler drain down during boiler outage window. The source of the trace amounts of H-3 was identified and fixed in October of 2023.

5 Tritium dose factor for bone is 0.00E+00; therefore, no hypothetical dose is calculated.
6 Organ doses are identical because the dose factors are identical for the same nuclide and pathway.
Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 13 Analysis of Release There were multiple abnormal liquid releases due to contamination found in the auxiliary boilers. Samples were counted to effluent LLDs for gamma and H-3, and any positive activity was used to quantify the release. The releases were documented in the effluent management software (OpenEMS) and the total organ dose was determined to be 2.27E-08 mrem to the child liver (1.13E-07% of annual limit) and 2.27E-08 mrem to the child total body (3.79E-07% of annual limit).
Heat Exchanger Leakage In July 2023, low-level tritium was identified in Unit 3 C-RHR system. The RHR system is designed to circulate water to remove heat from the reactor unit when necessary, by using a heat exchanger with river water as the cooling medium. The dose model assumes that contaminated torus water leaks into the river water running through 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 unexpectedly.
Analysis of Release It was assumed that the torus water released to the discharge canal contributed a conservative dose of 1.66E-12 mrem to the total body (child receptor). The release was conservatively calculated for three months. System was resampled following next system run, and results were found to be <LLD.
Gaseous Releases Contaminated Auxiliary Boiler While the boiler was in operation, the roof vent was opened to maintain system pressure, on startup, and low demand operations. The conservative assumption is that the steam released through the auxiliary boiler contained the same activity that was identified during liquid sampling and therefore, needed to be documented as a release. The highest identified H-3 activity concentration from either the steam/mud drums or the deaerator was used to quantify the release. There was one documented release of the steam from the auxiliary boiler containing activity in 2023. The steam flow rate was assumed to be the load rate % on the boiler, which is overly conservative, but there is no measurement of boiler exhaust flow rate.
The total dose to infant thyroid was 1.35E-07 mrem, 4.56E-05% of quarterly limit. The conservative nature of the release assumptions show that the dose impact is minimal to the public.
Missed Sampling There were no missed ODCM samples in 2023.
Radiation Monitors Out of Service for Greater than 30 days There were no radiation monitors out of service for greater than 30 days in 2023.
Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 14 Changes to the ODCM There was one revision made to the ODCM and to the ODCM Specifications (Appendix A) during 2023. Milk Farm J was removed from the REMP sampling program due to the herd being sold. Farms M-1C and M-4C were added to the program. In addition to the inclusion of two new farms, all sample identifiers were updated for the existing milk sampling locations. More information regarding this change can be found in the 2023 AREOR.
Violations There were no effluent release violations for the 2023 reporting period.
Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 15 Dose Assessment Introduction A dose assessment for PBAPS was conducted with the measured cumulative 2023 radioactive effluent source terms, provided in Attachment 2, "Effluent Summary," and the 2023 meteorological (MET) data. This dose assessment verifies 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 I.7 Liquid Dose Assessment Hydrologic Conditions and Receptor Locations of Interest PBAPS is located on the Conowingo Pond formed in the Susquehanna River by the Conowingo Dam. For 2023, the annual average river flow8 was measured as 3.63E+04 ft3/s.
Of the three separate flow regimes that were used in the original Appendix I submittal, the most limiting of them (<1.50E+04 ft3/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.
The annual average dilution factor9 at the Conowingo Intake is 5.40E+00 and the assumption for the reconcentration factor9 is 1.16E+00. The PBAPS shore width factor10 of 2.00E-01 was also used.
No invertebrate intake was examined because invertebrate ingestion pathways are not considered to be significant in the area close to PBAPS. The pathway factors for the various age groups, used to determine dose to the public from liquid effluents are shown in Table 6.

Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 16 Liquid Effluent Dose Assessment Conclusion For all permitted releases in 2023, the calculated total body dose was 1.93E-03 mrem and 2.89E-03 mrem to the limiting organ of child Liver.
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.
Gaseous Dose Assessment The gaseous dose assessment calculates the conservative dose at the limiting receptor location, as defined in the ODCM and at locations from the land-use census, using the 2023 meteorology to demonstrate compliance with 10 CFR 50, Appendix I. The assessment compares the current ODCM locations to the maximum locations from the land use census to ensure the current ODCM locations are still the most impactful dose locations.
Tables 7 and 8 report the dose calculated with the CY-PB-170-210 spreadsheet using the 2023 MET data and total gaseous activity released (summarized in Attachment 2), including C-14. Table 7 focuses on the two locations with the highest elevated dispersion factor (X/Q) from the Main Offgas Stack, while Table 8 highlights the two locations with the highest ground deposition factor (D/Q) from the Reactor Building Exhaust Vents. The X/Q values are very similar to those used in the ODCM, and therefore the differences in noble gas dose is minimal. The larger discrepancies between iodine, particulates, tritium (I/P/T) organ doses can be explained by the differences in pathways. Tables 7 and 8 assume that there is a milk pathway at each of the listed locations.
The ODCM defines the milk pathway at 1500m SW and the D/Qs are more comparable (2023 vent: 2.19E-09 1/m2 vs. ODCM vent: 1.58E-09 1/m2) and therefore, the dose calculated by ODCM methodology is more accurately representative of the dose to members of the public than the doses reported in Tables 7 and 8.

Peach Bottom Atomic Power Station Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 17 Gaseous Radioactive Effluent Dose Assessment Conclusion The conservative maximum dose was 8.14E-02 mrem with the maximum receptor as the child bone which is due to the incorporation of carbon-14 in the calculation. Without C-14, the maximum dose is 2.18E-03 mrem to the infant thyroid. The noble gas limiting air doses were 2.96E-02 mrad (gamma) and 2.02E-02 mrad (beta). Noble gas plume conservative dose was 2.87E-02 mrem to the total body and 3.74E-02 to the skin mrem for the year.
A dose assessment was performed for members of the public due to their activities inside the site boundary, per ODCMS 3.10.2.f. The locations where a member of the public would spend a significant amount of time inside the site boundary are two new vehicle checkpoints, approximately 780 feet ENE (Emergency checkpoint) and 910 feet NNE (Warehouse checkpoint) of the PBAPS Unit 2 and Unit 3 reactor building exhaust vents. Assuming continuous occupancy, the calculated total body and skin doses were 2.21E-01 mrem and 2.87E-01 mrem for the Emergency checkpoint and 2.46E-02 mrem and 3.18E-02 mrem for the Warehouse checkpoint, respectively. The noble gas limiting air doses were 2.29E-01 mrad (gamma) and 1.55E-01 mrad (beta) for the Emergency checkpoint and 2.54E-02 mrad (gamma) and 1.72E-02 mrad (beta) for the Warehouse checkpoint. These doses are overly conservative, as typically vehicles and their drivers are not at the checkpoints 24/7. The maximum organ dose from the inhalation pathway, not including C-14, is 6.47E-03 mrem for the Emergency checkpoint and 7.16E-04 mrem for the Warehouse checkpoint, both to the infant thyroid.
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 radiation monitor. Constellation uses a 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.15 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.
15 PBAPS uses specific Boiling Water Reactor assumptions because the fraction of C-14 that is in the CO2 form 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 Units 1, 2 and 3 Licensee: Constellation Energy Corporation PSEG Nuclear, LLC 18 ERRATA In 2021 and 2022, there was one section of the Effluent Summary Attachment that required revision. The percent of Gamma Air Dose and percent of Beta Air Dose did not have the correct dose limits applied to the calculation. Please see the corrected table sections below.
