Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D.C. 20555 Quad Cities Nuclear Power Station, Units I and 2 Facility Operating License Nos. DPR-29 and DPR-30 NRC Docket Nos. 50-254 and 50-265

Subject:

Quad Cities Nuclear Power Station's Radioactive Effluent Report for January through December 2003 The attached Quad Cities Nuclear Power Station's Radioactive Effluent Report for January through December 2003 is submitted in accordance with the Quad Cities Technical Specifications Section 5.6.3 and 10 CFR 50.36a.

Six abnormal releases occurred during 2003. These abnormal releases resulted in minor increases to normal plant radioactive effluents and are discussed in detail in this report.

The Main Chimney Flow Rate monitor was out of service for 78 days from September 22, 2003 to December 9, 2003 due to leaking sensing lines between the flow element and the flow transmitter. These sensing lines are routed through the ventilation duct and are not reasonably accessible. The extended out of service time was due to the time required to troubleshoot, plan, and install a modification to reroute new sensing lines and relocate the transmitter.

Should you have any questions concerning this letter, please contact Mr. W. J. Beck at (309) 227-2800.

Respectfully, ohy J. Tulon te Vice President Quad Cities Nuclear Power Station

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 7.17E-03 pCi/ml Service water 1.OE-05 pCi/ml

3.

Average Energy The average gamma energy used to calculate the alarm setpoints for the noble gas monitors was 0.933 Mev for the first quarter, and 0.951 Mev for the second quarter.

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 Sr89/90 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 Sr89/90 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.

K:1CHCScott\\EffluentsWAnnual Report DaIaMEffluent Report\\2OO312003 Effluent Report Data All Otrs.doc

CY-QC-1 20-722 Revision 0 ATTACHMENT 3 Annual Effluent Report Supplemental Information Page 3 of 5 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 Sr89/90 and Fe55. 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 Sr89/90 and Fe55 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.

a.

Liquid

1. A leak in the 1A Residual Heat Removal (RHR) heat exchanger was repaired in June 2002. There continues to be a small amount of radioactivity identified in the service water side of the heat exchanger. Investigation continues to determine its source. At this time, the relatively small amount of radioactivity identified 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 2A RHR heat exchanger service water side developed in October 2002. The activity 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. The leak is scheduled for repair in September 2003.

1. A release from the service building contaminated area ventilation system occurred from 4/26/03 to 5/02/03. The release occurred when OV-02 fan drive belt failed. With the fan stopped, the suction line of the fan pressurized and leaked past inlet modulating damper OVX-01 to atmosphere. Fan OV-02 discharges to the Turbine Building exhaust ventilation. Therefore, the air being released was a combination of Service Building air and Turbine Building exhaust air.

No measurable activity was detected at the point of release. However, since the majority of Main Chimney flow is Turbine Building ventilation exhaust, the measured activity at the Main Chimney was conservatively assigned to this release. The activity from this release was included in the normal monthly effluents and is also included in the "continuous" gaseous section of this report.

2.

Between January 2003 and April 2003, several nuclear fuel leaks were identified on U-1. Some leaks were suppressed. The leaking fuel was replaced in May 2003 during outage QI M16. The increased noble gas activity due to the fuel leaks resulted in an increase in the calculated effluent releases and was included in the normal monthly effluent releases during this period.

3.

On April 28, 2003, a nuclear fuel leak developed on U-2. The leak was successfully suppressed on June 10, 2003. The leaking fuel was replaced in June 2003 during outage Q2F59. The increased noble gas activity due to the fuel leak resulted in an increase in the calculated effluent releases and was included in the normal monthly effluent releases during this period.

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 5.01 E-05 jiCi/ml Service water 1.OE-05 pCi/ml

3.

Average Energy The average gamma energy used to calculate the alarm setpoints for the noble gas monitors was 1.02 Mev for the third quarter, and 1.00 Mev for the fourth quarter.

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 Sr89/90 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 Sr89/90 and gross alpha curies released values reported are actual. On a real time basis, the portion of the Mpercent of applicable 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.

K:kCH\\Scott\\Effluents\\Annua1 Report Data\\Effluent Report\\2003\\2003 Effluent Report Data All Qtrs.doc

CY-QC-1 20-722 Revision 0 ATTACHMENT 3 Annual Effluent Report Supplemental Information Page 3 of 5 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 Sr89/90 and Fe55. 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 Sr89/90 and Fe55 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.

A leak in the 1A RHR heat exchanger was repaired in June 2002. There continues to be a small amount of radioactivity identified in the service water side of the heat exchanger. Investigation continues to determine its source. At this time, the relatively small amount of radioactivity identified 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 2A RHR heat exchanger service water side developed in October 2002. On September 22, 2003, attempts to repair the heat exchanger were unsuccessful. The activity 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. A temporary modification was performed 1/15/04 that reduced the leakage. The heat exchanger was repaired in March 2004 during refuel outage Q2R17.
