1. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2013. 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, 2013, to December 31, 2013. 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 2013.

Parameter Unit 1 Unit 2 Gross Electrical Energy Generation 8,111,515 8,696,904 (Megawatt Hour (MWH))

Unit Service Factor 85.3 88.0 (Percent (%))

Unit Capacity Factor 87.0 89.4 (Maximum Dependable Capacity (MDC)) Net (%)

Unit I 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 27, 2013, entering the refueling outage U1C25. The unit attained criticality on May 18, 2013 and attained NFP on May 24, 2013. On December 13, 2013, a planned downpower to 24%

power was performed to support containment glowplug replacement work. The unit returned to NFP on December 16, 2013. 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. Unit 2 performed manual reactor trip and entered a forced outage on July 28, 2013 due to a Condensate Heater Bypass Control valve setpoint issue. The unit returned to NFP on August 1, 2013.

The unit performed a normal downpower and was manually tripped on October 2, 2013, entering the refueling outage U2C21. The unit attained criticality on November 11, 2013, and attained NFP on November 18, 2013. 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.

Appendix ALI.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 were no abnormal liquid releases and no abnormal gaseous releases in 2013.

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 2013 there were 90 liquid batch releases performed. The number of liquid batch releases for the four quarters in 2013 was 18, 24, 25, and 23, respectively.

Estimated doses (in mrem) to maximally exposed individuals via the liquid release pathways are given in Appendix A1.2 of this report.

Gaseous Releases During the first quarter of 2013 there were two batch releases from Gas Decay Tanks (GDT), one containment purge, and 102 Containment Pressure Reliefs (CPR). During the second quarter there was one batch release from GDTs and 108 CPR. During the third quarter there were four batch releases from GDTs and 119 CPR. During the fourth quarter there was one batch release from GDTs, two containment purges, and 62 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-0 133.

There were a total of eight GDT releases, three containment purges, and 391 CPR gaseous batch releases made during 2013.

In calculating the dose consequences for continuous and batch gaseous releases during 2013, 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 A1.2 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 23 shipments of radioactive waste made during 2013. 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 2013. Hourly meteorological data is available for review and/or inspection upon request.

IV. OFFSITE DOSE CALCULATION MANUAL (ODCM) 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 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 2013 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 2013 Annual Radiological Environmental Operating Report.

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 8.56E-03 1.50E-02 4.53E-02 7.51 E-02 Total Body Air 2.1OE-04 2.90E-04 9.80E-04 3.10E-04 Skin 3.40E-04 4.70E-04 1.60E-03 9.20E-04 Liquid TB 2.42E-02 9.22E-03 2.51 E-02 8.12E-03 Liquid Organ 2.42E-02 9.25E-03 2.51 E-02 8.30E-03 C14 (Annual) 2.20E+00 Direct Radiation 0 0 1 -0 0 Total 5.75E-02 3.42E-02 9.81 E-02 2.29E+00 Grand Total Dose (Total Body or any other Organ) mrem 2.48E+00 Annual Dose Limit (mrem) 25 Percent of limit 9.93E+00 3

The following data reflects a comparison with 2009 annual dose data (the last year without calculating C-14 dose), 2013 annual dose data, and 2013 annual dose data with C-14 added.

This indicates that 2013 was a 'normal' dual unit outage year with respect to radioactive effluents and allows for easier comparison. The table is presented as follows:

Annual Dose (mrem)  % of limit 2009 2.60E-01 1.04 2013 2.83E-01 1.13 2013 with C-14 2.48 9.93 VI. RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS There were no release pathways unmonitored for greater than 30 days.

VII. NOTEWORTHY CONDITIONS IDENTIFIED IN 2013 During the Fourth Quarter of 2012, an intermittent fault was identified on the CNP 60-Meter Meteorological Tower that resulted in a large number of invalid data hours collected.

A Condition Report (2012-2305) was initiated and repair work performed. The issue appeared to be a connection to the Delta Temperature instrumentation. Repairs yielded better data collection results in December 2012, however the intermittent fault returned and the system yielded additional invalid data hours during the First and Second Quarters of 2013. Additional repair work was performed when conditions allowed for safe work on the tower, and this resulted in the problem being positively identified as cabling fault grounding out the 10 Meter Delta Temperature instrumentation on the Main 60 Meter Tower. The repairs on the cable and instrumentation were successful at eliminating the intermittent fault and data collection has returned to near 100% valid hours.

The meteorological data gathered from the 60 meter tower during valid hours along with data substituted in for invalid hours from a secondary 10 Meter Temperature instrumentation located onsite by our meteorological third party vendor indicate normal weather patterns consistent with historical norms. The updated data was utilized in the dose calculations performed in the MIDAS software to ensure accurate dose assessments. The Joint Frequency Tables attached are taken using the primary instrumentation only as there is no method available in the software to illustrate the data substitution utilized by the vendor.

This methodology of data substitution has always been used for any invalid hours, since the usage of MIDAS software at CNP, to ensure the most accurate dose calculations and reporting. The large number of invalid data hours is unusual though, so it is important to clarify that this did not impact the ability to calculate public dose negatively as a process of data substitution by our vendor already was in place to address any invalid hours.

Carbon-14 Supplemental Information for the 2013 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 4

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 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" 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 2013 results in a site total of 18.03 Curies produced.

C-14 releases from PWRs occur primarily as a mix of organic carbon (methane) and inorganic (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 3.61 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 209 hours0.00242 days <br />0.0581 hours <br />3.455688e-4 weeks <br />7.95245e-5 months <br /> of batch gaseous releases performed during 2013 and the assumption that 70% of the C-14 released is from gaseous batch releases. 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 1.74 mrem to the bone and a whole body dose of 0.461 mrem, for a combined total C-14 dose of 2.20 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.

2013 GPI Sample Data Analysis of the Sample Data The Groundwater Protection Initiative (GPI) Sample Data for 2013 indicates no groundwater contamination in excess of the reporting threshold of 2.OOE-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 2013 Annual Radiological Environmental Operating Report. There were no positively identified radionuclides from plant effluents detected in any of the GPI well samples.

The LLD value used for tritium counting of the samples varied between 9.42E-7 and 9.63E-7uCi/mL, depending on which scintillation counter was used. This is well below the required maximum LLD value of 2.OOE-6 uCi/mL per the ODCM, While no tritium values were found above LLD for 2013, 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 Absorptiof Pond, a licensed pathway and part of plant design, or the result of recapture deposition of tritium from licensed radioactive gaseous release points. The 2013 results were expected considering the reduction in tritium released to the Absorption Pond and a reduction in rainfall 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 2013 continue to reflect normal expectations and behaviors as they relate to recaptured tritium for the weather conditions observed in 2013. All gamma samples taken in support of the GPI were less than detectable.

The sample data indicates that no radioactive spills or unidentified leaks have occurred in 2013 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.
