I. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2018. This is m accordance with the requirements of CNP Technical Specification (TS) 5.6.3.

The table below summarizes the pertinent statistics concerning the Plant's operation during the period from January 1, 2018, to December 31, 2018. 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 2018.

Parameter Unit 1 Unit2 Gross Electrical Energy Generation 9,601,477 8,554,617 (Megawatt Hour (MWH))

Unit Service Factor 100.0 80.6 (Percent (%))

Unit Capacity Factor 103.07 81.23 (Maximum Dependable Capacity (MDC)) Net(%)

Unit 1 entered the reporting period in Mode 1 at Nominal Full Power (NFP). Small power adjustments were made to facilitate main turbine valve testing throughout the year.

The unit performed a downpower to 57% to support repairs of the West Main Feed Pump on July 14, 2018 and returned to NFP following repairs on July 15, 2018. The unit exited the reporting period at NFP.

Unit 2 entered the reporting period in Mode 1 at Nominal Full Power (NFP). Small power adjustments were made to facilitate main turbine valve testing throughout the year.

The unit performed a normal downpower and was manually tripped on March 1, 2018, entering refueling outage U2C24. The unit attained criticality on May 5, 2018, and performed a manual reactor trip from 30% during the subsequent startup due to a Moisture Separator Drain Tank Hi Level Alarm. The unit attained criticality on May 10, 2018 and attained NFP on May 18, 2018. The.unit exited the reporting period at NFP.

II. RADIOACTIVE RELEASES AND RADIOLOGICAL IMPACT ON MAN Since a number of release points are common to both units, the release data from both units are combined to form this two-unit, Annual Radioactive Effluent Release Report (ARERR).

Appendix Al.I through A2.4 of this report present the information 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.

I

There were no abnormal liquid or gaseous releases in 2018. 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 1 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 2018 there were 104 liquid batch releases performed. The number of liquid batch releases for the 151, 2nd, 3rd, and 4111 quarters in 2018 were 32, 51, 10, and 11, respectively.

Estimated doses (in. mrein) to maximally exposed individuals via. the liquid release pathways are given in Appendix Al.2 of this report.

Gaseous Releases During the first quarter of 2018 there was one batch release from Gas Decay Tanks (GDT),

one containment purge, one system tank vent, and 65 Containment Pressure Reliefs (CPR).

During the second quarter there were two batch releases from GDTs and 72 CPR. During the third quarter there were five batch releases from GDTs, one system tank vent, and 78 CPR. During the fourth quarter there were four batch releases from GDTs and 80 CPR.

The CPR continue to be listed as batch releases as described in Nuclear Regulatory Commission Inspections 50-315/89017 (DRSS); 50-316/89016 (DRSS) for CNP, dated June 13, 1989. Doses continue to be calculated utilizing continuous criteria as allowed by NUREG-0133. There were a total of 12 GDT releases, one containment pt1rge, two system tank vents, and 295 CPR gaseous batch releases made during 2018.

In calculating the dose consequences for continuous and batch gaseous releases during 2018, 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.

Solid Waste Disposition There were 26 shipments of radioactive waste made during 2018. These included shipments made from the site to various radioactive waste processors for ultimate disposal.

III. METEOROLOGICAL Appendices A2.1, 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 2018. Hourly meteorological data is available for review and/or inspection upon request.

IV. OFFSITE DOSE CALCULATION MANUAL {ODCM) CHANGES The ODCM, PMP-6010-0SD-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 Berrien County be limited to no more than 25 rnrem to the total body or any organ (except the thyroid, which is limited to no more than 7 5 rnrem) over a period of 12 consecutiv~ months to show conformance with the requirements of 40 CFR Part 190. The maximum cumulative dose to an individual from liquid and gaseous effluents during 2018 was well within the ODCM limits. Measurements using thermoluminescent 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 2018 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:

Dose (mrem) 1st Qtr 2nd Qtr 3rd Qtr 4th Qtr I&p 2.64E-02 2.17E-02 2.78E-02 1.98E-02 Total Bodv Air 3.30E-04 3.10E-04 1.10E-03 4.00E-04 Skin 5.30E-04 7.SOE-04 1.90E-03 6.90E-04 Liquid TB 2.64E-02 1.01 E-02 1.81 E-03 1.10E-02 Liquid Orqan 2.67E-02 1.10E-02 1.82E-03 1.10E-02 Direct Radiation 0 0 0 0 Quarterly Dose Total 8.04E-02 4.39E-02 3.44E-02 4.29E-02 Sum of Quarter Doses 2.02E-01 C14 (Annual) Dose 2.25E+OO Grand Total Dose (Total Body or anv other Orc:ian) mrem 2.45E+OO Annual Dose Limit (mrem) 25 Percent of limit 9.81 E+OO 3

The following data reflects a comparison with 2009 annual dose data (the last year without calculating C-14 dose), 2018 annual dose data, and 2018 annual dose data with C-14 added.

This indicates that 2018 annual dose was 'typical' for a single unit outage year in regards to radioactive effluents. The table is presented as follows:

Annual Dose (mrem)  % of limit 2009 2.60E-01 1.04 2018 2.02E-01 0.81 2018 with C-14 2.45 9.81 VI. RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS Steam Generator :Slowdown Monitor R-19 was removed from service as part of the planned Radiation Monitor System (RMS) ReplacementProject on October 15, 2018 and exited the year out of service. The appropriate compensatory sampling actions were taken throughout as releases on this pathway continued. The monitor is being upgraded and modernized, and this inoperable time period> 30days was planned for/ expected due to having to install all the hardware, wiring backbone, network, and displays. The monitor is expected to return to service following the Unit 1 U1C29 Outage in the spring 2019. The RMS replacement project will eventually upgrade and replace multiple effluent monitors, so additional reporting is anticipated in future annual reports. There were no other release pathways with inoperable monitors for greater than 30 days.

VII. NOTEWORTHY CONDITIONS IDENTIFIED IN 2018 The RMS Replace~ent Project initiated physical plant alterations in preparation of upgrading and modernizing the plant's ability to monitor radioactive effluents. The first effluent monitor to be physically removed and replaced was R-19, the steam generator blowdown effluent monitor. This major project will enhance reliability and capabilities while maintaining all regulatory requirements per our License and Technical Specifications. The Offsite Dose Calculation Manual revisions will be expected to occur in 2019 reflecting the transition and later again once the project is fully implemented. No changes were require~ in 2018 for the work that was performed.

Carbon-14 Supplemental Information for the 2018 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.

4

Since the U.S. Nuclear Regulatory Commission (NRC) published Regulatory Guide (RG) 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. RG 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 term scaling factor and actual electrical generation (in MWH) produced during 2018 results in a site total of 19.5 Curies produced.

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 2.73 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. A 'p' factor of 0.33 is determined utilizing the time of batch gaseous releases performed during 2018 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 1.88 mrem to the bone and a whole body dose of 0.374 mrem, for a combined total C-14 dose of 2.25 mrem. This is less than the dose limit of 15 mrem/unit to any organ prescribed in 10 CFR 50, Appendix I, and the 40 CFR Part 190 limit of 25 mrem for total body and for any organ ( S75 mrem for thyroid).

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

Analysis of the Sample Data The Groundwater Protection Initiative (GPI) Sample Data for 2018 indicates no groundwater contamination in excess of the reporting threshold of2.00E-5 uCi/mL for tritium. Gamma spectroscopy was performed on all Radiological Environmental Monitoring Program wells quarterly. Those results are not actual GPI results so are not included in the ARERR, but are part of CNP' s 2018 Annual Radiological Environmental Operating Report. There were no positively identified gamma radionuclides from plant effluents detected in any of the GPI well samples, and one well with trace levels of tritium just above detection limits.

The LLD value used for tritium counting of the samples varied between 9.42E-7 and 9.98E-7uCi/mL, depending on which scintillation counter was used. This is well below the required maximum LLD value of2.00E-6 uCi/mL per theODCM.

No tritium values were found significantly above LLD for 2018, though 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 ofrecapture deposition of tritium from licensed radioactive gaseous release points. The 2018 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 2018 continue to reflect normal expectations and behaviors as they relate to recaptured tritium for the weather conditions observed. Well MW-28 lies close to the vent stacks in the predominant wind direction, so it is expected to observe recaptured tritium from precipitation periodically.

The sample data indicates that no radioactive spills or unidentified leaks have occurred in 2018 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.
