I. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2016. This is in 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, 2016, to December 31, 2016. 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 2016.

Parameter Unit 1 Unit 2 Gross Electrical Energy Generation 8,586,842 7,272,912 (Megawatt Hour (MWH))

Unit Service Factor 90.l 74.l (Percent(%))

Unit Capacity Factor 91.9 74.5 (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 normal downpower and was manually tripped on March 23, 2016, entering refueling outage U1C27. The unit attained criticality on April 27, 2016, and attained NFP on May 2, 2016. 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 was manually tripped on July 6, 2016, entering a forced outage due to a steam leak. The unit attained criticality on July 12, 2016, and attained NFP on July 14, 2016. On July 21, 2016, the unit performed a controlled downpower to 48% power at the request of grid operators due to grid conditions, returning to NFP on August 2, 2016. The unit performed a normal downpower and was manually tripped on October 5, 2016, entering refueling outage U2C23. The unit exited the reporting period shutdown.

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.

Appendix A 1.1 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.

1

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

There was one abnormal liquid release and no abn01mal gaseous releases in 2016. The abnormal liquid release occurred on October 31, 2016, with approximately 1,500 gallons of water leaking past boundary valves on the normal licensed steam generator drainage pathway over a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period. The water was Secondary side water contained inside a steam generator, which acts as a heat transfer medium from the Reactor Coolant filled Primary side piping. This steam generator water was subsequently discharged to Lake Michigan via the Circulating Water system. This water contained tritium at 15,000 picocuries per liter, which is below the 20,000 picocurie per liter drinking water limit.

Though the nuclide level was low, the leakage was unplanned and met the criteria for being an abnormal release of liquid effluent. The total curies of tritium released from the event were 1. 71 E-04 curies, assuming a conservative 3000 gallons of released water to bound the event. This curie content was added to the liquid release totals and the associated public dose accounted for. Action Request AR# 2016-12597 documented this event and subsequent repairs.

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. Specification 3.1.1, Multi-Purpose Canister (MPC), provides assurance that there are not radioactive effluents from the ISFSI.

Liquid Releases During 2016 there were 89 liquid batch releases performed. The number of liquid batch releases for the four quarters in 2016 was 14, 20, 22, and 33, respectively.

Estimated doses (in mrem) 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 2016 there were seven batch releases from Gas Decay Tanks (GDT), one containment purge, one system tank venting, and 134 Containment Pressure Reliefs (CPR). During the second quarter there were three batch releases from GDTs, one system tank venting, and 130 CPR. During the third quarter there were four batch releases from GDTs and 150 CPR. During the fourth quarter there were two batch releases from GDTs, one containment purge, one system tank venting, and 86 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 16 GDT releases, two containment purges, three system tank vents, and 500 CPR gaseous batch releases made during 2016.

In calculating the dose consequences for continuous and batch gaseous releases during 2016, the meteorological data measured at the time of the release were used.

2

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 33 shipments of radioactive waste made during 2016. 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 2016. Hourly meteorological data is available for review and/or inspection upon request.

IV. OFFSITE DOSE CALCULATION MANUAL (ODCM) CHANGES The ODCM, PMP-601O-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 Berrien 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 conformance with the requirements of 40 CFR Part 190. The maximum cumulative dose to an individual from liquid and gaseous effluents during 2016 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 2016 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:

This indicates that 2016 annual dose was 'typical' for a dual unit outage year with an extended outage duration in regards to radioactive effluents. The table is presented as follows:

Annual Dose (mrem)  % of limit 2009 2.60E-01 1.04 2016 7.34E-01 2.94 2016 with C-14 2.71 10.8 VI. RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS There were no release pathways unmonitored for greater than 30 days.

VII. NOTEWORTHY CONDITIONS IDENTIFIED IN 2016 The Inadvertent draining of a steam generator in 2016 was discussed in Section II above as an abnormal release. While noteworthy, it had minimal impact on effluent releases or public dose exposure due to the very low tritium curie content of the water.

In addition, it is considered noteworthy that in 2016 two small fuel rodlet defects were identified to have the potential to impact effluents. These defects increased the release of fission product gasses and iodine isotopes into the reactor coolant, which in tum increased activity levels in the effluent streams. The increases contributed to a small impact to the site overall public dose exposure by approximately 1.2% of the limit over the course of the year (2015 was 2.42mRem/ 9.68% of limit vice 2.71mRem/ 10.8% oflimit in 2016). The public dose due to operations at CNP remain a small fraction of the legal limits and efforts to keep public dose As Low As Reasonably Achievable (ALARA) were largely successful.

Carbon-14 Supplemental Information for the 2016 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 (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 tenn 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. EPRl 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 2016 results in a site total of 17.0 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. This equates to 2.38 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 most predominant. A 'p' factor of 0.33 is determined utilizing the time of batch gaseous releases performed during 2016, the time available for photosynthesis in plants, and the assumption that 70% of the C-14 released is from gaseous batch releases.

A fmiher 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.

5

The final results indicated a calculated organ dose from C-14 to a child at the site boundary of 1.64 mrem to the bone and a whole body dose of 0.326 mrem, for a combined total C-14 dose of 1.97 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 ( :::_75 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.

IX. ERRATA There are no errata attached for 2016.

Analysis of the Sample Data The Groundwater Protection Initiative (GPI) Sample Data for 2016 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 ofCNP's 2016 Annual Radiological Environmental Operating Report. There were no positively identified gamma radionuclides from plant effluents detected in any of the GP! well samples, and a single well with trace levels of tritium just above detection limits.

The LLD value used for tritium counting of the samples varied between 9.42£-7 and 9.59E-7uCi/mL, depending on which scintillation counter was used. This is well below the required maximum LLD value of2.00E-6 uCi/mL per the ODCM.

No tritium values were found significantly above LLD for 2016, 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 oftritiated 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 2016 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 2016 continue to reflect normal expectations and behaviors as they relate to recaptured tritium for the weather conditions observed in 2016. 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 2016 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.
