I. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2011. This is in accordance with the requirements of CNP Technical Specification 5.6.3.

The table below summarizes the pertinent statistics concerning the Plant's operation during the period from January 1, 2011, to December 31, 2011. 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 2011.

Parameter Unit 1 Unit 2 Gross Electrical Energy Generation 7,984,732 9,950,856 (Megawatt Hour (MWH))

Unit Service Factor 88.1 100.0 (Percent (%))

Unit Capacity Factor 85.5 102.2 (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 downpower and manually tripped on March 12, 2011, entering a planned maintenance outage to perform hydrogen leak repairs on the Main Generator.

The unit attained criticality on March 17, 2011, and attained NFP on March 19, 2011.

The unit performed a normal downpower and manual trip to enter the refueling outage U1C24 on September 21, 2011. The unit attained criticality on October 25, 2011, and attained NFP on October 31, 2011. 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 exited the reporting period at NFP.

I. 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.

All liquid and gaseous releases were well within Offsite Dose Calculation Manual (ODCM) liniits and Federal Limits.

There were no abnormal liquid releases and no abnormal gaseous releases in 2011.

1

Liquid Releases During 2011 there were 73 liquid batch releases performed. The number of liquid batch releases for the four quarters in 2011 was 17, 10, 26, and 20, respectively.

Estimated doses (in millirem) 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 2011 there were 96 Containment Pressure Reliefs (CPR). During the second quarter there were 91 CPR. During the third quarter there was five batch releases from GDT, two containment purges, and 92 CPR. During the fourth quarter there was one batch release from GDT and 103 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 6/13/1989. Doses continue to be calculated utilizing continuous criteria as allowed by NUREG-0133. There were a total of six GDT releases, two containment purges, and 382 CPR gaseous batch releases made during 2011.

In calculating the dose consequences for continuous and batch gaseous releases during 2011, the meteorological data measured at the time of the release were used.

The estimated doses (in millirem) 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 17 shipments of radioactive waste made during 2011. 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 2011. Hourly meteorological data is available for review and/or inspection upon request.

IV. OFFSITE DOSE CALCULATION MANUAL (ODCM) CHANGES The Offsite Dose Calculation Manual, PMP-6010-OSD-001, was not revised during the report period.

2

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 millirem to the total body or any organ (except the thyroid, which is limited to no more than 75 millirem) 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 2011 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 2011 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 C-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 2.08E-02 1.58E-02 5.95E-02 2.83E-02 Total Body Air 2.OOE-04 3.20E-04 1.50E-03 5.80E-04 ,

Annual Dose Limit (mrem) 25 Percent of limit 1.15E+01 The following data reflects a comparison with 2009 annual dose data (the last year without calculating C-14 dose), 2011 annual dose data and 2011 annual dose data with C-14 added.

This indicates that 2011 was a 'normal' single 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 2011 2.17E-01 0.87 2011 with C-14 2.87 11.5 VI. RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS There were no release pathways unmonitored for greater than 30 days.

VII. NOTEWORTHY CONDITIONS IDENTIFIED IN 2011 While not a condition directly relating to CNP station performance, the March 2011 event in Fukushima, Japan deserves special attention, focusing on the details and how they relate to or impact CNP. This is intended as a high level discussion and is not intended as an in-depth report.

The Fukushima power station suffered an accident beyond its design basis, undergoing a massive earthquake followed by a very large tsunami (tidal wave) which caused significant damage to the entire region. The facility withstood the earthquake in relatively good condition considering the magnitude. The tsunami engulfed the nuclear station, damaging much of the safety equipment and resulting in a complete loss of power. The loss of power prevented cooling water from being provided to the reactor core and to stored spent fuel in adjacent spent fuel pools. The lack of cooling water resulted in fuel assembly damage that caused the release of large quantities of gaseous radioactive fission products. The eventual restoration of emergency power supplies allowed cooling water to be pumped into the reactors and spent fuel pools, but damage suffered from the earthquake (cracks, etc) allowed some of this cooling water bearing some radioactive fission products to leak out of the buildings and enter the neighboring ocean water. As of the time of this writing, the conditions at Fukushima have greatly improved with significant progress on maintaining the reactors in a "cold shutdown" configuration with releases of radioactive effluents being performed in a controlled and deliberate manner. The NRC (via SECY-1 1-0093) and the Japan Nuclear Energy Safety Organization (JNES) have released summaries of the events at Fukushima where more specific details can be found. An important fact identified in the reports was that no fatalities as a result of radiological exposure from the Fukushima event occurred, however the earthquake and tsunami left over 25,000 people dead or missing.

The majority of the released fission products were short lived gaseous isotopes as a result of the damaged fuel assemblies. While the number of curies released into the environment was very large, the short half lives has caused the majority to have decayed away within weeks of their release. Trace amounts of longer lived isotopes were detected over North America several weeks after the event, having been carried across the ocean via the jet stream and via storm fronts. The US nuclear industry commenced monitoring for these expected nuclides shortly after the Fukushima event, and CNP participated in this monitoring. Results of the monitoring were shared with the industry and the regulating agencies governing CNP. Only gaseous Iodine and Cesium isotopes impacted CNP, as the liquid releases into the ocean occurred into the Pacific and has no pathway to CNP.

CNP performed airborne and precipitation samples commencing on March 24, 2011 and maintained this until May 24, 2011. Observable traces of the Fukushima related Iodine-i131 were found in precipitation samples on March 24t, and found on portable air samples taken near REMP locations on March 28th. Several regional nuclear stations detected cesium isotopes as well, mainly Cs-137. Results found by CNP were comparable to results observed at other nuclear stations within the region and were not attributable to licensed radioactive material from CNP or any other US nuclear station. An evaluation was performed which validated that CNP was not the source of the detectable 1-131 found in samples collected on and offsite (AR# 2011-3838). These isotopes are not included in dose calculations contained within this report as they were not part of the legally released 4

VII. NOTEWORTHY CONDITIONS IDENTIFIED IN 2011 While not a condition directly relating to CNP station performance, the March 2011 event in Fukrushima, Japan deserves special attention, focusing on the details and how they relate to or impact CNP. This is intended as a high level discussion and is not intended as an in-depth report.

licensed material performed by CNP. The REMP program will continue to monitor the environment around CNP and will be an indicator of further impacts from Fukushima.

Carbon-14 Supplemental Information for the 2011 Annual Radioactive Effluent Release Report.

Carbon-14 (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 carbon-14 in Earth's biosphere is about 300 million Curies, of which most is in the oceans.

Since the NRC published Regulatory Guide 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. This year's report will be the second report by CNP including C-14, but 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, Rev 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 (MWH) produced during 2011 results in a site total of 21.7 Curies released.

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 4.34 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 151 hours0.00175 days <br />0.0419 hours <br />2.496693e-4 weeks <br />5.74555e-5 months <br /> of batch gaseous releases performed during 2011 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.

5

The final results indicated a calculated organ dose from C-14 to a child at the site boundary of 2.09 mrem to the bone and a whole body dose of 0.554 mrem, for a combined total C-14 dose of 2.65 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 affect on the health and safety of the general public.

2011 GPI Sample Data Analysis of the Sample Data The Groundwater Protection Initiative (GPI) Sample Data for 2011 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 here, but are part of CNP's 2011 Annual Radiological Environmental Operating Report that is submitted to the Nuclear Regulatory Commission. There were no positively identified radionuclides from plant effluents detected in any of the quarterly well samples other than the expected tritium values associated with documented plant events and recapture tritium from licensed radioactive gaseous release points.

The LLD value used for counting of the samples varied between 8.38E-7 and 9.72E-7uCi/mL, depending on which scintillation counter was used. This is well below the required minimum LLD value of 2.OOE-6 uCi/mL.

Values found above the LLD were not abnormal, unexpected, or inconsistent with past sampling history. The samples observed above LLD 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.

Specifically, tritium results greater than LLD were the results of the 2009 release of radioactive effluent to the Absorption Pond as documented in AR 848816 and the 2009 version of this report or from the recapture of tritium from gaseous effluents. Wells MW-22, MW-24, MW-25, MW-26, MW-27, W-15, W-1 1, W-12, W-13 and W-14 are positioned to monitor Absorption Pond percolation. The groundwater transit of the tritium from the Absorption Pond mirrors the expected travel predicted by hydrogeologic studies. Wells W-2, W-4, W-5, and W-6 results continue to reflect the recapture of tritium from legally released gaseous effluents and are closely monitored for changes indicating some other condition. Wells located inside the Protected Area of the plant are subject to recapture deposition of tritium and show occasional sample results above LLD values following rainfalls and snow melt.

The sample data indicates that no radioactive spills or unidentified leaks have occurred in 2011 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, with flow direction and behavior acting as described in the plant licensing documents.
