I. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2010. 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, 2010, to December 31, 2010. 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 2010.

Parameter Unit 1 Unit 2 Gross Electrical Energy Generation 8,078,628 8,097,054 (Megawatt Hour (MWH))

Unit Service Factor 89.7 83.4 (Percent (%))

Unit Capacity Factor 86.5 83.1 (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 was manually tripped on March 3, 2010, and entered the scheduled U1C23 refueling outage. The unit attained criticality on April 9, 2010, and attained NFP on April 12, 2010. The unit performed a rapid downpower to approximately 50% power on May 2, 2010 due to an oil leak and high vibrations on the East Main Feed Pump (MFP).

The unit returned to NFP on May 16, 2010 after MFP repairs. The unit performed a rapid downpower to approximately 50% power on December 13, 2010, due to lowering vacuum on the East MFP. The unit returned to NFP on December 15, 2010, after MFP condenser cleaning actions. 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 and a moderator temperature coefficient test. The unit was manually tripped on October 6, 2010, and entered the scheduled U2C 19 refueling outage. The unit attained criticality on December 5, 2010, and attained NFP on December 9, 2010. 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 AI.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 2010.

Liquid Releases During 2010 there were 89 liquid batch releases performed. The number of liquid batch releases for the four quarters in 2010 was 24, 15, 19, and 31, 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 2010 there were six batch releases from Waste Gas Decay Tanks (GDT), two containment purges, and 72 Containment Pressure Reliefs (CPR). During the second quarter there were two batch releases from GDT and 83 CPR. During the third quarter there was one batch release from GDT and 108 CPR. During the fourth quarter there were five batch releases from GDT, one containment purge, and 62 CPR. The CPR continue to be listed as batch releases as described in Nuclear Regulatory Commission Inspections 50-315/89016 (DRSS) and 50-316/89017 (DRSS). Doses continue to be calculated utilizing continuous criteria as allowed by NUJREG-0133. There were a total of 14 GDT, three containment purges, and 325 CPR gaseous batch releases made during 2010.

In calculating the dose consequences for continuous and batch gaseous releases during 2010, 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 19 shipments of radioactive waste made during 2010. These included shipments made from the site to various radioactive waste processors for ultimate disposal.

I/. 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 2010. 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.

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 2010 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 the 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:

This indicates that 2010 was a 'normal' dual unit outage year with respect to radioactive effluents and allows for easier comparison.

The table is presented as follows:

VI. RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS There were no release pathways unmonitored for greater than 30 days.

VII. NOTEWORTHY CONDITIONS IDENTIFIED IN 2010 1.) A tritium excursion in the Turbine Room Sump (TRS), an approved release pathway, commenced on October 29, 2010, with the discovery occurring via daily Absorption Pond samples. The sample result was above the Lower Limit of Detection (LLD) used for tritium (8.50E-7 micro curie/ml, uCi/ml) and resulted in additional grab samples taken to validate the results. The subsequent grab samples of the Absorption Pond indicated tritium levels between <8.50E-7 and 6.55E-6 uCi/ml. A TRS grab sample obtained on 10/29/11 indicated 1.90E-6 uCi/mI. The TRS composite sample from the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> obtained at 0105 on 10/30/10 indicated 7.26E-6 uCi/ml.

A TRS grab sample obtained at 0209 on 10/30/10 indicated 1.31E-4 uCi/mI with a subsequent TRS grab sample at 0300 indicating a decrease to 3.83E-5 uCi/ml. No gamma activity was detected.

Subsequent investigation revealed that Operations personnel had drained approximately 150 gallons of Unit 2 Component Cooling Water (CCW) through a floor drain to the TRS. This clearance activity (2-Cl9-R-CCW-CCWC-0815) was performed to allow work on 2-CCR-460, Excess Letdown HX 2-HE-13 CCW Return Containment Isolation Valve, and was done under the direction of the clearance permit process and occurred late in the evening on 10/29/10. Unit 2 CCW contained a tritium concentration of 1.64E-1 uCi/ml. This volume of CCW is sufficient to cause these elevated levels in the TRS and the TRS discharges to the Absorption Pond. The Absorption Pond flows through the groundwater aquifer to Lake Michigan and there are groundwater monitoring wells in this pathway that have indicated tritium from the Absorption Pond historically. No drinking water is impacted by releases into the Absorption Pond.

This draining activity resulted in elevated tritium levels of approximately 1.31 E-04 uCi/ml in the TRS, an approved release pathway, and the sump was pumped to the site absorption pond. The 10 CFR 20, Appendix B, limit of 1.0 E-3 micro curie/ml was challenged but not exceeded. This release pathway is not the preferred path for CCW draining as it has the potential to impact groundwater via the Absorption pond.

No adverse groundwater impacts are expected, though increased well monitoring is being performed to track any potential plume as the water percolates naturally from the Absorption Pond to Lake Michigan per design. No reporting levels were met, and it is not expected that any downstream wells will indicate any reportable concentrations in tritium levels. It would be anticipated that wells similar to those impacted by the 2009 release of CCW to the TRS and Absorption Pond should see comparable sample results early in 2011 and continue to observed as the plume passes into Lake Michigan per design.

Various procedural enhancements for Operations and Chemistry procedures were identified and provided with actions to complete. Training to Operators was identified and documented with an action on the significance of draining CCW to the 4

TRS. An action was provided to add postings or labeling to all Auxiliary Building drains that provide a flow path to the TRS denying draining of CCW without Environmental concurrence. There was also an industry Operating Experience distributed through INPO documenting this event. There were no reportability concerns or notifications required during this event, since the releases were through licensed pathways and all dose fully accounted for. These actions are designed to prevent a future repeat of this condition. All radioactive liquids released during this condition were released through licensed release pathways (the TRS is such a pathway) and at no time posed any threat to the health and safety of the public. This issue is documented in CNP's Corrective Action Program under AR 2010-11695.

2.) A greater number of containment pressure reliefs were performed in 2010 as seen in the increased number of gaseous batch releases. This was the result of maintaining a narrower containment pressure band to improve reactor coolant pump seal leakoff performance. This is not abnormal, but was a notable change from last year.

Carbon-14 Supplemental Information for the 2010 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, starting in 2010 the nuclear industry will be required to report the quantity and dose impact of C-14 here in the United States. This year's report will be the first 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). 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 2010 results in a site total of 17.4 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 5

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 3.47 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 171 hours0.00198 days <br />0.0475 hours <br />2.827381e-4 weeks <br />6.50655e-5 months <br /> of batch gaseous releases performed during 2010 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. This results in a calculated organ dose to a child at the site boundary of 1.37 mrem to the bone and a whole body dose of 0.272 mrem. These are per unit dose results so the total dose to a child would be 2.74 mrem to the bone and 0.544 mrem to the total body. 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 75 mrem for any organ.

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.

Analysis of the Sample Data The Groundwater Protection Initiative (GPI) Sample Data for 2010 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 the 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 sample other than the expected tritium values associated with documented plant events.

The LLD value used for counting of the samples varied between 8.17E-7 and 9.60E-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. The Introduction contains a section titled Noteworthy Conditions Identified In 2010 which will provide details on the release to the Absorption Pond.

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-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. Wells OW-2, W4, W-5, and W-6 results continue to reflect the recapture of tritium from legally released gaseous effluents are closely monitored for changes indicating some other condition.

The sample data indicates that no radioactive spills or unidentified leaks have occurred in 2010 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.
