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 2.0-5 and 2.0-6 from the Offsite Dose Calculation Manual Part II Chapter 2. 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 2.0-1 and 2.0-2 from the Offsite Dose Calculation Manual Part II Chapter 2. The MPC values used for the monitors were as follows:

Radwaste discharge 1.32E-05 ýtCi/ml Service water 1.OOE-05 ýtCi/ml

3.

Average Energy The average gamma energy used to calculate the alarm setpoints for the noble gas monitors was:

8.52E-01 MeV for Quarter 1 7.94E-01 MeV for Quarter 2 7.18E-01 MeV for Quarter 3 7.50E-01 MeV for Quarter 4

4.

Measurements and Approximations of Total Radioactivity

a.

Fission and Activation Gases

b.

lodines

c.

Particulates a,b,c. 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 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 2006 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.

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. Beginning in October 2006, the 2A RHR heat exchanger was not included in the monthly report. The residual radioactivity was no longer included because it became an insignificant source. The small amount of radioactivity originating from the 2A RHR heat exchanger during the time period January-September 2006 is 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 Q1R18. Beginning in October 2006, the 1B RHR heat exchanger was not included in the monthly report. The residual radioactivity was no longer included because it became an insignificant source. The small amount of radioactivity originating from the 1 B RHR heat exchanger during the time period January-September 2006 is included in the "continuous" liquid section of this report.

b.

Gaseous

1.

A small nuclear fuel leak developed in November 2005 on Unit 2. The leaking fuel was identified and suppressed for the remainder of the cycle.

The leaking fuel was replaced during Q2R18 in April of 2006. The radioactivity attributed to this nuclear fuel leak was included in the monthly effluent calculations.

2.

In March of 2006, a waste collector filter was changed out. Air samples taken near an adjacent door in radwaste indicated that a small amount of activity was released to the environment. The small amount of activity outside the door indicates that some outward airflow occurred while the door was open. The small amount of particulate gaseous radioactivity released was estimated to be 0.18 pCi. This nominal activity was included in the monthly effluent calculations.
