I. INTRODUCTION This report discusses the radioactive discharges from Unit 1 and Unit 2 of the Donald C. Cook Nuclear Plant (CNP) during 2007. 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, 2007, to December 31, 2007. 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 2007.

Parameter Unit 1 Unit 2 Gross Electrical Energy Generation 9,559,146 8,389,164 (Megawatt Hour (MWH))

Unit Service Factor 99.6 85.5 (Percent (%))

Unit Capacity Factor 101.1 86.1 (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 experienced a reactor trip on August 28, 2007, on steam flow/feed flow mismatch caused by a power supply failure on feedwater turbine controls. The unit attained criticality on August 29, 2007, and returned to NFP on August 30, 2007. 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 commenced end of cycle coast down load reduction on September 5, 2007, and entered the scheduled U2C17 refueling outage on September 15, 2007. The unit attained criticality on November 6, 2007, and attained NFP on November 10, 2007. 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.

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

There were no abnormal liquid or gaseous releases.

I

Liquid Releases During 2007 there were 105 liquid batch releases performed. The number of liquid batch releases for the four quarters in 2007 were, 17, 14, 39 and 35, respectively.

Estimated doses (in millirem) to maximally exposed individuals via the liquid release pathways are given in Appendix A1.2 of this report. The fourth quarter composite sample results were not available at the time of this report and will be included in next year's report.

For similar reasons the fourth quarter of 2006 individual dose report is included as page A1.2-5.

Gaseous Releases During the first quarter of 2007 there were no batch releases from Waste Gas Decay Tanks (GDT) and 68 Containment Pressure Reliefs (CPR). During the second quarter there was one batch release from a GDT and 64 CPR. During the third quarter there were five batch releases from GDT, two containment purges, and 50 CPR. During the fourth quarter there were four batch releases from GDT and 68 CPR. 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 10 GDT, two containment purges, and 250 CPR gaseous batch releases made during 2007.

In calculating the dose consequences for continuous and batch gaseous releases during 2007, 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 46 shipments of radioactive waste made during 2007. These included shipments made from the site and the various radioactive waste processors to the ultimate disposal site.

1II. 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 2007. 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 revised during the report period. Copies of Revision 22 are included as part of the report.

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 2007 was well within the ODCM limits. Measurements using thermoluminescent dosimeters (TLD) at 1,1 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.

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 will be 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 radiation monitors inoperable for greater than 30 days while there was a release via that pathway.

VRS-2500, Unit 2 vent stack radiation. monitor, particulate and iodine media was flooded out with rainwater during two separate instances, one on 7/19/07 and again on 7/26/07. The media was dried and counted as information data. These rainwater events are documented in Action Request 816309 and provided here as information.

VII. CONCLUSION Based on the information presented in this report, it is concluded that the CNP Units 1 and 2 performed their intended design function with no demonstrable adverse affect on the health and safety of the general public.

2007 Effluent and Waste Disposal Annual Report 3 AVERAGE ENERGY The average energy (E) of the radionuclide mixture in releases of fission and activation gases as defined in Regulatory Guide 1.21, Appendix B, Section A.3 is not applicable because the limits used for gaseous releases are based on calculated dose to members of the public. Release rates are calculated using an isotopic mix from actual samples rather than average energy.

4 MEASUREMENTS and APPROXIMATIONS of TOTAL RADIOACTIVITY 4.1 Fission and Activation Gases Sampled and analyzed on a 4096 channel analyzer and HpGe detector. Tritium analysis is performed using liquid scintillation counter.

4.2 Iodines Sampled on iodine adsorbing media and analyzed on a 4096 channel analyzer and HpGe detector.

4.3 Particulates Sampled on a glass filter and analyzed on a 4096 channel analyzer and HpGe detector. Sr-89 and Sr-90 analyses performed by offsite vendor.

4.4 Liquid Effluents Sampled and analyzed on a 4096 channel analyzer and HpGe detector. Tritium analysis is performed using liquid scintillation counter. Fe-55, Sr-89 and Sr-90 analyses performed by offsite vendor. Ni-63 is also currently being analyzed by the offsite vendor in response to evaluation of the 10 CFR 61 sample results.
