Exelon Generation Company 1. Regulatory Limits a. For Noble Gases: (per unit)Dose rate 1. Less than 500 mrem/year to the whole body 2. Less than 3000 mrem/year to the skin.Dose Gamma Radiation 1. Less than or equal to 5 mrad/quarter.

2. Less than or equal to 10 mrad/year.

Beta Radiation 1. Less than or equal to 10 mrad/quarter.

2. Less than or equal to 20 mrad/year.

b,c. For lodine-1 31, for lodine-1 33, and for all radionuclides in particulate form with half-lives greater than 8 days.Dose Rate 1. Less than 1500 mrem/year.

Dose 1. Less than or equal to 7.5 mrem/quarter.

2. Less than or equal to 15 mrem/year.

For Liquid: (per site)Less than or equal to 3 mrem to the whole body during any calendar quarter.Less than or equal to 10 mrem to any organ during any calendar quarter.Less than or equal to 6 mrem to the whole body during any calendar year.Less than or equal to 20 mrem to any organ during any calendar year.Page 8 of 70 Quad Cities Nuclear Power Station 2005 Annual Radioactive Effluent Release Report Supplemental Information
2. Maximum Permissible Concentration a,b,c. For fission and activation gases, iodines, and particulates with half-lives greater than 8 days, allowable release limits are calculated by solving equations 10.1 and 10.2 from the Offsite Dose Calculation Manual. The alarm setpoint is conservatively set at approximately 10% of the 1 OCFR20 limit.d. For liquid effluents allowable release limits are calculated by solving equations 10.3 and 10.4 from the Offsite Dose Calculation Manual. The MPC values used for the monitors were as follows: Radwaste discharge 1.32E-05 gCi/ml Service water 1.OOE-05 gCi/ml 3. Average Energy The average gamma energy used to calculate the alarm setpoints for the noble gas monitors was: 1.00E+00 MeV for Quarter 1 9.72E-01 MeV for Quarter 2 9.35E-01 MeV for Quarter 3 8.97E-01 MeV for Quarter 4 4. Measurements and Approximations of Total Radioactivity
a. Fission and Activation Gases: b. lodines: c. Particulates:

The main chimney and reactor building ventilation exhaust systems are continually monitored for iodines and particulates.

These samples are pulled every 7 days and analyzed by gamma isotopic.

The particulate papers are composited every 31 days and sent to a vendor for Sr-89/90 and gross alpha analysis.

Noble gas grab samples are pulled and analyzed by gamma isotopic weekly. Tritium samples are pulled and analyzed every month.The Sr-89/90 and gross alpha curies released values reported are actual. On a real time basis, the portion of the "percent of applicable limit" for these contributors is reported based on projections using the previous six (6) months available data. The actual results are obtained by editing the ODCM software inputs when the vendor results become available.

Therefore, the "percent of applicable limits" in this report are actual.Page 9 of 70 Quad Cities Nuclear Power Station 2005 Annual Radioactive Effluent Release Report Supplemental Information The continuous strip chart recorders for the monitors on the release points are reviewed monthly for spikes and the activity released is calculated.

An additional calculated activity for noble gases is added to the main chimney release each month. This calculation is done because most of the grab samples show less than the lower limit of detection due to the low amount of activity and the large dilution flow at the sample point. The calculation takes into account the normal offgas train and the gland steam contribution to the release.The average flow at the release points is used to calculate the curies released.d. Liquid Effluents The River Discharge Tanks are analyzed before discharge by gamma isotopic.

A composite representative portion of this sample is saved. This is composited with other discharges that occurred every 31 days and is analyzed for tritium and gross alpha. The monthly composites are composited quarterly and sent to a vendor for Sr-89/90 and Fe-55 analyses.

The discharge bay is sampled every 31 days and analyzed by gamma isotopic, for tritium and gross alpha. It is sampled quarterly and sent to a vendor for Sr-89/90 and Fe-55 analysis.

On a real time basis, the portion of the "percent of applicable limit" for these contributors is based on projections using scaling factors. The actual results are obtained by editing the ODCM software inputs when the vendor results become available.

Therefore, the "percent of applicable limits" in this report are actual.The tank volumes and activities are used to calculate the curies released for the River Discharge Tank. The total water released during the quarter and the activity is used to calculate the diluted activity released at the discharge bay, from batch discharges.

e. Estimated Total Error Percent The estimated total error percents were calculated by taking the square root of the sum of the squares of errors for sampling and measurement parameters.
f. Less than the lower limit of detection

(<LLD)Samples are analyzed such that the Technical Specification LLD requirements are met. When a nuclide is not detected during the quarter, then <LLD is reported.

The most conservative LLD's used for counting effluent samples are included in this report.Page 10 of 70 Quad Cities Nuclear Power Station 2005 Annual Radioactive Effluent Release Report Supplemental Information

17 2. Total time: 1.47E+04 minutes 3. Maximum time: 9.22E+02 minutes 4. Average time: 8.65E+02 minutes 5. Minimum time: 7.95E+02 minutes 6. Average stream flow: 62.6 gpm (discharge) 3.39E+05 gpm (dilution)

b. Gaseous NONE.6. Abnormal Releases a. Liquid 1. A leak into the 2A RHR heat exchanger service water side developed in October 2002. The heat exchanger was repaired in March 2004 during refuel outage Q2R17.The relatively small amount of residual radioactivity identified from the leak continues to be included in the normal monthly effluents and is also included in the "continuous" liquid section of this report.2. A leak into the 1 B RHR heat exchanger service water side developed in September 2004. The heat exchanger was repaired in March 2005 during refuel outage Q1 R18. The relatively small amount of residual radioactivity identified from the leak continues to be included in the normal monthly effluents and is also included in the "continuous" liquid section of this report.b. Gaseous 1. A small nuclear fuel leak developed in November 2005 on U-2. The leaking fuel was identified and suppressed for the remainder of the cycle.The leaking fuel was replaced during Q2R18 in April 2006.Page 11 of 70 Quad Cities Nuclear Power Station 2005 Annual Radioactive Effluent Release Report Supplemental Information

Not Applicable for QCNPS e. Total Body Doses to the Population and Average Doses to Individuals in the Population from Gaseous Effluents to a Distance of 50 Miles: Not Applicable for QCNPS f. Doses From Liquid and Gaseous Effluent to Members of the Public Due to Their Activities Inside the Site Boundary for the Report Period: Not Applicable for QCNPS. Any member of the public that is onsite for a significant period will be issued a Thermo Luminescent Dosimeter (TLD).9. Liquid and Gaseous Effluent Radiation Monitors and Instrumentation Unavailability for the Period Beyond the Requirements of the ODCM, Including Sampling Deviation:

No ODCM monitors were unavailable for greater than 30 days in 2005.Page 12 of 70 Quad Cities Nuclear Power Station 2005 Annual Radioactive Effluent Release Report Supplemental Information Submitted
