INTRODUCTION This report discusses the radioactive discharges from Unit I and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2023.

This is in accordance with the requirements of CNP Technical Specification (TS) 5.6.3.

The table below swnmarizes the pertinent statistics concerning the Plant's operation during the period from January 1, 2023, to December 31, 2023. The data in this table and the descriptive information on plant operation are based upon the respective unit's Monthly Operating Reports, Performance Indicators, and Control Room Logs for 2023.

The unit performed a rapid downpower to 52% power on July 12, 2023 to support repair work on the West Main Feed Pump. The unit returned to NFP on July 15, 2023. The unit performed a normal downpower and was manually tripped on October 14, 2023 entering refueling outage Ul C32. The unit attained criticality on November 13, 2023 and returned to NFP on November 18, 2023. The unit performed a planned power reduction to 23%

power on December I 1, 2023 to support repairs of a steam leak. The unit reached NFP on December 15, 2023. The unit exited the reporting period at NFP.

Unit 2 entered the reporting period in Mode 1 at NFP. Small power adjustments were made to facilitate main turbine valve testing throughout the year. The unit performed a planned power reduction to 91% to support Main Turbine repair work on January 18, 2023. The unit attained NFP on January 19, 2023. The unit exited the reporting period at NFP.

II.

RADIOACTIVE RELEASES AND RADIOLOGICAL IMPACT ON MAN Since a nwnber of release points are common to both units, the release data from both units are combined to fonn this two-unit, Annual Radioactive Effluent Release Report (ARERR). Appendix Al.I through A2.4 of this report present the infonnation in accordance with Section 5.6.3 of Appendix A to the Facility Operating Licenses, as specified in the Technical Specifications, Regulatory Guide 1.21, and 10 CFR Part 50, Appendix I.

The "MIDAS System" is a computer code that calculates doses due to radionuclides that were released from the CNP.

All liquid and gaseous releases were well within Offsite Dose Calculation Manual (ODCM) limits and federal limits.

There were no abnormal liquid or gaseous releases in 2023. There were no spills or leaks of radioactive liquids requiring voluntary notifications per the Industry Groundwater Protection Initiative or site procedures.

The Independent Spent Fuel Storage Installation (ISFSI) impacts are included with Unit I and Unit 2 statistics. The ISFSI cask system does not create any radioactive materials or have any radioactive waste treatment systems. Therefore, specific operating procedures for the control of radioactive effluents are not required. Technical Specifications for the HI-Storm 100 Cask System, Specification 3.1.1, Multi-Purpose Canister (MPC), provides assurance that there are not radioactive effluents from the ISFSI.

Liquid Releases During 2023 there were 62 liquid batch releases performed. The number of liquid batch releases for the 151, 2nd, 3"1, and 4th quarters in 2023 were 10, 7, 16, and 29, respectively.

Estimated doses (in mrem) to maximally exposed individuals via the liquid release pathways are given in Appendix A 1.2 of this report.

Gaseous Releases During the first quarter of 2023 there were five batch releases from Gas Decay Tanks (GDn and 61 Containment Pressure Reliefs (CPR). During the second quarter there were three batch releases from GDTs and 58 CPR. During the third quarter there were five batch releases from GDTs and 57 CPR. During the fourth quarter there were three batch releases from GDTs, one containment purge, one system tank vent, and 71 CPR. The CPR continue to be listed as batch releases as described in Nuclear Regulatory Commission Inspections 50-315/89016 (DRSS); 50-316/89017 (DRSS) for CNP, dated June 13, 1989. Doses continue to be calculated utilizing continuous criteria as allowed by NUREG-0133. There was a total of 16 GOT releases, one containment purge, one system tank vent, and 247 CPR gaseous batch releases made during 2023.

In calculating the dose consequences for continuous and batch gaseous releases during 2023, the meteorological data measured at the time of the release were used.

The estimated doses (in mrem) to maximally exposed individuals via the gaseous release pathways are given in Appendix Al.2 of this report. For individuals that are within the site boundary, the occupancy time is sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the site boundary.

2

Solid Waste Disposition There were 13 shipments of radioactive waste made during 2023.

These included shipments made from the site to various radioactive waste processors for ultimate disposal.

III.

METEOROLOGICAL Appendices A2.l, A2.2, A2.3, and A2.4 of this report contain the cumulative joint frequency distribution tables of wind speed and wind direction, corresponding to the various atmospheric stability classes for the first, second, third, and fourth quarters of 2023.

Hourly meteorological data is available for review and/or inspection upon request.

IV.

OFFSITE DOSE CALCULATION MANUAL CODCM) CHANGES The ODCM, PMP-6010-OSD-001, was not revised during the report period.

V.

TOTAL DOSE Section 3.2.5 of the ODCM requires that the dose or dose commitment to a real individual from all uranium fuel cycle sources in Benien County be limited to no more than 25 mrem to the total body or any organ (except the thyroid, which is limited to no more than 75 mrem) over a period of 12 consecutive months to show confonnance with the requirements of 40 CFR Part 190. The maximum cumulative dose to an individual from liquid and gaseous effluents during 2023 was well within the ODCM limits. Measurements using thennoluminescent dosimeters (TLD) at 12 onsite stations indicate that the dose due to direct radiation is consistent with preoperational and current control (background) levels.

This is fully evaluated in CNP's 2023 Annual Radiological Environmental Operating Report. Additional TLD dosimetry installed by Radiation Protection department programs monitor dose received by individuals on site as visitors.

The annual dose to the maximum individual will be estimated by first, summing the quarterly total body air dose, the quarterly skin air dose, the quarterly critical organ dose from iodines and particulates (I&P), the quarterly total body dose from liquid effluents, the quarterly critical organ dose from liquid effluents, and the Radiological Environmental Monitoring Program onsite direct radiation TLD data. These quarterly values are summed with the annual Carbon-14 dose and compared to the annual total body limit for conservative reasons. The table that follows here represents the above written description:

RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS The Radiation Monitor System has undergone an extensive replacement project to upgrade and modernize the equipment to support the expected operational lives of the two CNP units. This work completed in April of 2020. One effluent monitor pathway continues to have issues regarding this project with the background radiation levels due to the detector sensitivities. 12-RRS-lO0l(a)/ IO0l(b) channels of the Waste Disposal liquid effluent monitors were declared inoperable on July 24, 2020, and required software changes in order to address the higher background detected due to the increased sensitivity. The actual room area radiation levels are relatively unchanged, but the new redundant detectors are far more sensitive and capable of detecting much lower radiation levels. The software was redeveloped and delivered to CNP in December, 2021, however this was not successful in restoring the monitors back to operability. On 4/20/2023, 12-RRS-1001 (b) channel was restored to operable following extensive periods of flushing and a passing channel operability test. This restores the monitoring on this pathway and makes 12-RRS-1001 operable. The 1001 (a) channel is having a new detector installation scheduled to restore redundancy. All releases on this pathway have been and remain in compliance with ODCM and any required compensatory actions.

There were no other release pathways with inoperable monitors for greater than 30 days.

VII.

NOTEWORTHY CONDITIONS IDENTIFIED IN 2023 A rain event on September 6, 2023 resulted in loss of iodine and particulate sample media on our Unit 2 Vent Stack effluent radiation monitor 2-VRS-2500 and the 2-VSX-2501 backup sample system for that week. Rain water overloaded the moisture traps on the sample lines and resulted in the media becoming wet and unusable for counting. The continuous monitoring and sampling were quickly restored by draining the traps and replacing the sample media. This reduced the runtime on the media and reduced the possible lower limit of detection for the remaining period that week. The air space being sampled is common to Unit 1 which did not suffer any rain water intrusion and subsequent samples did not show any unusual activity. Continuous monitoring of our Auxiliary Building airspace remained active throughout and the ODCM allows for short interruptions to accommodate sampling and activities like draining trap water.

Carbon-14 Supplemental Information for the 2023 Annual Radioactive Effluent Release Report.

C-14 has a 5730 year half-life and is a naturally occurring radionuclide produced by cosmic ray interactions in the atmosphere. C-14 is a relatively low energy beta emitter. Nuclear weapons testing in the 1950s and 1960s significantly increased the amount of C-14 in the atmosphere. C-14 is also produced in commercial nuclear reactors, but the amounts produced are much less than those produced naturally, from weapons testing, or coal burning power plants. The inventory of C-14 in Earth's biosphere is about 300 million Curies, of which most is in the oceans.

Since the U.S. Nuclear Regulatory Commission published Regulatory Guide (RO) 1.21, Revision 1, in 1974, the analytical methods for determining C-14 have improved.

Coincidentally, the radioactive effluents from commercial nuclear power plants over the same period have decreased to the point that C-14 is likely to be a principal radionuclide in gaseous effluents. Based on these reasons and a desire to adjust policy to align with international standards, the nuclear industry was required to report, starting in 2010, the quantity and dose impact of C-14 here in the United States. The dose will be reported both with and without C-14 so a comparison to 2009 can be made, keeping in mind the differing standards.

The quantity of C-14 released to the environment can be estimated by use of a C-14 source term scaling factor based on power generation (Ref. RO 1.21, Revision 2). A recent study recommends a source term scaling factor of approximately 9.0 to 9.8 Curies/GWe-yr for a Westinghouse Pressurized Water Reactor (Ref. EPRI 1021106, "Estimation of Carbon-14 in Nuclear Plant Gaseous Effluents", dated December 23, 2010). A scaling factor of 9.4 Curies/GWe-yr was assumed for this report. Using this source tenn scaling factor and actual electrical generation (in MWH) produced during 2023 results in a site total of 20.63 Curies produced.

5

C-14 releases from Pressurized Water Reactors (PWR) occur primarily as a mix of organic carbon (methane) and inorganic carbon (carbon dioxide). As a general rule, C-14 in the primary coolant is essentially all organic with a large fraction as gas. Any time the primary coolant is exposed to an oxidizing environment ( during shutdown or refueling), a slow transformation from an organic to an inorganic species occurs.

Various studies documenting measured C-14 releases from PWRs suggest an average 80% organic fraction with the remainder being carbon dioxide, of which 70% is assumed to be released from gaseous batch releases. This equates to 2.89 Curies released as carbon dioxide which is available for the food pathway through photosynthesis to vegetation.

Dose is calculated utilizing the methodology prescribed in RG 1.109, Appendix C, with the vegetation dose being the predominant pathway. A 'p' factor of 0.33 is determined utilizing the time of batch gaseous releases petformed during 2023 and the time available for photosynthesis in plants. A further reduction to the vegetation and leafy vegetable dose is warranted due to the limited growing season in Michigan, which was conservatively limited to nine months.

The final results indicated a calculated organ dose from C-14 to a child at the site boundary of 1.99 mrem to the bone and a whole body dose of 0.396 mrem, for a combined total C-14 dose of 2.39 mrem. This is less than the dose limit of 15 mrem/unit to any organ prescribed in IO CFR 50, Appendix I, and the 40 CFR Part 190 limit of 25 mrem for total body and for any organ ( 95 mrem for thyroid).

The C-14 dose is now the major contributor and will consistently be about 8-10 times higher than the pre-2010 calculations. This dose will only change with online power generation, so it will not alter significantly unless the plant is shutdown for an extended period.

VIII.

CONCLUSION Based on the information presented in this report, it is concluded that CNP Units 1 and 2 petformed their intended design function with no demonstrable adverse effect on the health and safety of the general public.

bohald C. Cook Nuclear Plant Annual Radlological Effluent Release Report 2023 2023 NEI GROUNDWATER PROTECTION INITIATIVE SAMPLE DATA A1.3-1

Donald c. Cook Nuclear Plant Annual Radlologlcal Effluent Release Report 2023 Analysis of the Sample Data The Groundwater Protection Initiative (GPI) Sample Data for 2023 indicates no groundwater contamination in excess of the reporting threshold of 2.00E-5 uCi/mL for tritium. Gamma spectroscopy was performed on all Radiological Environmental Monitoring Program (REMP) wells quarterly. Those results are not actual GPI results so are not included in the ARERR, but are part of CNP's 2023 Annual Radiological Environmental Operating Report. There were no positively identified gamma radionuclides from plant effluents detected in any of the GPI well samples, and no wells with levels of tritium above detection limits.

The Lower Limit of Detection (LLD) value used for tritium counting of the samples was 9.45E-7 or 9.83E-7, depending on lab equipment used. This is well below the required maximum LLD value of 2.00E-6 uCi/mL per the ODCM.

Values found above the LLD are not abnormal, unexpected, or inconsistent with past sampling history. The samples observed above LLD historically were expected results from the release of tritiated water into the Absorption Pond, a licensed pathway and part of plant design, or the result of recapture deposition of tritium from licensed radioactive gaseous release points. The 2023 results were within expected parameters considering the reduction in tritium released to the Absorption Pond and typical rainfall recapture of tritium experienced.

Wells located inside the Protected Area of the plant are subject to recapture deposition of tritium and may show occasional sample results above LLD values following rainfalls and snow melt.

The results observed In 2023 continue to reflect normal expectations and behaviors as they relate to recaptured tritium for the weather conditions observed. It was a drier year resulting in less recaptured tritium, as shown by the lack of positive tritium sample results.

The sample data indicates that no radioactive spills or unidentified leaks have occurred in 2023 impacting groundwater.

The sample results indicate proper well placement to ensure the protection of the groundwater and early identification of any abnormal conditions involving groundwater. This is validated by the demonstrated ability to monitor percolation from the Absorption Pond and recaptured tritium in precipitation, with flow direction and behavior acting as described in the plant licensing documents A1.3-2
