I. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2008. This is in accordance with the requirements of CNP Technical Specification 5.6.3.

The table below summarizes the pertinent statistics concerning CNP's operation during the period from January 1, 2008, to December 31, 2008. 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 2008.

Parameter Unit 1 Unit 2 Gross Electrical Energy Generation 5,829,281 9,696,184 (Megawatt Hour (MWH))

Unit Service Factor 61.6 98.5 (Percent (%))

Unit Capacity Factor 62.3 99.3 (Maximum Dependable Capacity (MDC)) Net (0)

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 February 2, 2008, due to high vibrations experienced on the Main Turbine. The unit entered Mode 3 Hot Shutdown following the event.

Unit 1 attained criticality on February 3, 2008, and returned to NFP on February 6, 2008.

The unit commenced end of cycle coast down load reduction on March 23, 2008, and entered the scheduled U1C22 refueling outage on March 26, 2008. The unit attained criticality on April 29, 2008, and attained NFP on May 4, 2008. Unit 1 reduced power to 90%' on June 27, 2008, to investigate and repair a Main Condenser tube leak. The unit returned to NFP On June 30, 2008. The unit was manually tripped on September 20, 2008, due to Main Turbine blade failure. The unit entered Mode 5 Cold Shutdown following the event and exited the reporting period at Mode 5 Cold Shutdown.

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 commenced a downpower to 54% on January 11, 2008, for maintenance on the West Main Feed Pump.

Unit 2 returned to NFP on January 13, 2008. On April 2, 2008, Unit 2 performed a 25%

downpower and isolated a Main Condenser due to a tube leak. The unit returned to NFP later. on April 2, 2008. On May 16, 2008, Unit 2 performed a downpower to Mode 2 to remove the Main Turbine from service for maintenance. The reactor remained critical at 3% until work was complete, and was followed by a power escalation to NFP on May 18, 2008. On August 7, 2008, the unit experienced a 200 megawatt load rejection caused by a Low Pressure Turbine Stop valve 'C' failing closed. This briefly lowered power to approximately 95% before load was restored. On August 15, 2008, Unit 2 performed a controlled shutdown to perform Stop Valve 'C' maintenance, entering Mode 3 Hot Shutdown on August 17, 2008. The unit attained criticality on August 21, 2008, and returned to NFP on August 22, 2008. The unit exited the reporting period at NFP.

II. RADIOACTIVE RELEASES AND RADIOLOGICAL IMPACT ON MAN Since a number of release pQints are common to both units, the release data fiom both units are combined to form this two-unit, Anmual Radioactive Effluent Release Report.

Appendix Al.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 CNP.

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

There was one abnon-nal liquid release and no abnormal gaseous releases in 2008. The abnormal liquid release occurred when a Component Cooling Water (CCW) sample cooler failed, allowing approximately 1577 gallons of CCW water to leak into the Circulating Water system. This allowed a flowpath from the CCW system into Unit I steam generator (SG) sample lines that were discharged to the SG blowdown sampling recovery system which was routed to the Unit 2 SG blowdown release path downstream of the Unit 2 SG blowdown radiation monitor. It was determined through an investigation that the leak commenced on November 7, 2008, and was identified and isolated on November 10, 2008, with the leak rate calculated to be approximately 1.5 liters per minute. This release was unplanned and was not monitored by liquid effluent release monitors; however, the CCW system is monitored with radiation monitoring equipment which was in service and indicated no abnormal readings during the time period of the leak. Calculations performed during the investigation demonstrated that using the most conservative dilution values (230,000 gpm for a single Circulating Water pump) that no 10 CFR 20, Appendix B, limits were exceeded for all detected isotopes in the CCW. Three Circulating Water pumps were actually in service providing additional dilution flow. It should be noted that CCW is a system designed to act as a heat transfer "go between" for Reactor Coolant System components and systems containing lake water, containing little activity other then tritium.

Calculations for activity concentrations at the Circulating Water discharge point were 2.OE-9 microcuries/gram for tritium (limit = 1.OE-3 microcunies/gram) and 2.73E-14 microcuries/gram cesium-137 (limit = 1.OE-6 microcuries/gram). No other isotopes were identified. Corrective actions were initiated and the sample cooler was repaired.

Liquid Releases During 2008 there were 85 liquid batch releases performed. The numbers of liquid batch releases for each of the four quarters in 2008 were 34, 26, 15, and 10, respectively.

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

2

Gaseous Releases During the first quarter of 2008, there were four batch releases from Waste Gas Decay Tanks (GDT), one containment purge, and 71 Containment Pressure Reliefs (CPR). During the second quarter, there were four batch releases from GDT and 53 CPR. During the third quarter, there were four batch releases from GDT, one containment purge, and 43 CPR.

During the fourth quarter, there were four batch releases from GDT and 26 CPR. The CPR continue to be listed as batch releases as described in Nuclear Regulatory Commission Inspections 50-315/89016 (DRSS) and 50-316/8917 (DRSS). Doses continue to be calculated utilizing continuous criteria as allowed by.NUREG-0133. There were a total of.

16 GDT, two containment purges, and 193 CPR gaseous batch releases made during 2008.

In calculating the dose consequences for continuous and batch gaseous releases during 2008, 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 70 shipments of radioactive waste made during 2008. These included shipments made from the site and the various radioactive waste processors to the ultimate disposal site.

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 2008. 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 2008 was well within the ODCM limits. Measurements using thermoluminescent dosimeters (TLD) at 11 offsite 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.

3

The annual dose to the maximum individual will be estimaited 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 and compared to the annual limit. The table that follows here represents the above verbal description:

RADIATION MONITORS INOPERABLE GREATER THAN 30 DAYS There were no release pathways unmonitored for greater than 30 days. One radiation monitor channel on a release pathway was inoperable for greater than 30 days while there was, a release via that pathway; however, there was backup monitoring capability in service which continued to monitor the pathway while repairs were made.

Action Request 827570 documents operability issues with VRA-1503, Unit 1 Vent Stack Iodine Radiation Monitor, which were noted on March 10, 2008, actions were taken, monitoring was conducted, further actions were warranted and taken and completed April 10, 2008. Based on a past operability determination, it was concluded that the monitoring channel was inoperable for an excess of 30 consecutive days, from February 2, 2008, through March 10, 2008. The backup iodine collection system was in service for the total time period with the exception of filter media changeout. This fulfilled PMP-6010-OSD-001, Offsite Dose Calculation Manual, Attachment 3.7, item d, for continuous analysis frequency. The system is sampled weekly, which provided the delay in identifying the problem and ensuring correction until sufficient data points were acquired to make a determination. This is being documented here for information due to the past operability determination conclusion. Once the issue was identified, it was remediated within 30 days and the monitor was not inoperable for that entire time period.

VII. 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.
