Measurements and Approximations of Total Radioactivity

a.

Fission and Activation Gases, lodines, and Particulates Containment batch releases are analyzed for noble gas and tritium before being discharged by gamma isotopic and scintillation, respectively. Gaseous decay tanks are analyzed for noble gas before being discharged by gamma isotopic. Released activity is normally calculated using volume of release, which is determined by change in tank or containment pressure.

The Auxiliary Building ventilation exhaust system is continually monitored for iodines and particulates. These samples are pulled every 7 days and analyzed by gamma isotopic. The particulate samples are also analyzed quarterly for gross alpha and Sr-89/90.

Noble gas and tritium grab samples are pulled and analyzed weekly by gamma isotopic and scintillation, respectively. The average flow at the release points are used to calculate the curies released.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units.

The secondary side of both units contain tritium. Very small amounts of tritium are continually released to the atmosphere from secondary components through packing leaks, tank vents, the main condenser, etc. Bounding calculations have been performed to show that very large leaks (1000 gpd) for extended periods (1 month) at normal secondary tritium concentrations, would provide an insignificant increase (1 E-5 mrem) in offsite dose.

No gaseous effluent radiation instrumentation was inoperable beyond the time allowed in the ODCM during 2009.

The calculated offsite dose to the public from station gaseous effluents remains low and a small percentage of the quarterly and annual Offsite Dose Calculation Manual (ODCM) limits.

b.

Liquid Effluents The liquid release tanks are analyzed before discharge by gamma isotopic and for tritium. A representative portion of this sample is saved. This is composited, every 31 days, with other discharges that occurred and is analyzed for tritium and gross alpha. The batch composites are composited quarterly and sent to a vendor for Sr-89/90 and Fe-55 analysis. Circulating Water Blowdown, Condensate Polisher Sump and Waste Water Treatment are analyzed weekly by gamma isotopic and for tritium. These weekly samples are composited monthly.

The monthly composites are then composited quarterly and sent to a vendor for Sr-89/90 and Fe-55 analysis.

Tank volumes and activities are used to calculate the curies released for the tanks released.

The total volume of water released and the measured activity is used to calculate the diluted activity released at the discharge point from batch discharges.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units.

Due to extreme cold weather, the Exelon Pond composite sampler experienced frozen components and not enough sample was collected for the week of 1/12/09 to 1/19/09 to allow valid analysis. The condition was corrected with the installation of backup sample tubing and the composite sampler provided normal sampling the following week.

On 1/21/09, due to extreme cold weather, the Circulating Water Blowdown composite sampler suction hose was frozen for one day. The condition was corrected with the installation of a backup sample line. The weekly composite sample for 1/19/09 to 1/26/09 did not contain sample for 1/21/09.

On 4/27/09, the Exelon Pond pump composite sampler had no weekly sample. The pond pump was operating during the week and a sample should have been collected. At the time this problem was identified, the pond pump had been shut down and sampler troubleshooting could not be performed. The next time the pump was operated on 4/30/09, troubleshooting revealed that the sample aliquot timer needed adjustment. The timer was adjusted and proper sample collections were restored.

On 7/14/09, the Vacuum Breaker #1 compositor sample isolation valve was identified as not functioning due to build up of iron deposits from the ground water pumped through the system. No sample was being collected. A work request was created and the sample valve was cleaned on 7/15/09. The sample valve function returned to normal and subsequently provided the needed samples.

On 11/23/09, the Exelon Pond composite sampler did not have a sample for the week of 11/16/09 to 11/23/09. A review of the Operations logs revealed that the Exelon Pond pump ran only 73 minutes during the week. Since the Exelon Pond composite sampler only samples every two hours, this short pump run time during this week did not allow enough run time for a valid sample to be collected. The sampler was checked on 11/23/09 and verified functioning properly, and a valid sample was collected the following week.

On 12/7/09, the Exelon Pond composite sampler did not have a valid weekly sample.

Following the discovery of a lack of sample, the composite sampler was checked and was functioning properly. No cause for the missed sample could be determined and a valid sample was collected the following week.

A review of these events indicates four lack of sample events related to Exelon Pond sampling. As issue report has been entered into the station Corrective Action Program to evaluate enhancements to the sample system monitoring and/or maintenance to improve performance.

There were two incidents of liquid effluent radiation instrumentation being inoperable beyond the time allowed in the ODCM during 2009. These event descriptions are located on page 19, item 5.

The calculated offsite dose to the public from station liquid effluents remains low and a small percentage of the quarterly and annual Offsite Dose Calculation Manual (ODCM) limits.

c.

Less than the lower limit of detection (<LLD).

Samples are analyzed such that the Offsite Dose Calculation Manual (ODCM) LLD requirements are met. When a nuclide is not detected during the quarter then <LLD is reported.

Errata for Previous Annual Radioactive Effluent Release Reports The text portion of the 2008 Annual Radioactive Effluent Release Report listed three abnormal gaseous releases. Two of those abnormal releases were Unit Common released and were properly listed in the second quarter of 2008 on the Unit Common Gaseous Effluents Supplemental Release Information. The third abnormal release was a Unit 2 release. This release was inadvertently left out of the Unit 2 Gaseous Effluents Supplemental Release Information table. It should have been listed in the second quarter of the Unit 2 Gaseous Effluents Supplemental Release Information as shown below:

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2009 UNIT 1 AND 2 COMBINED (Docket Numbers 50-456 and 50-457)

1.

In 2009, there were no changes to the Process Control Program.

2.

In 2009, there were no changes to the station's radioactive waste systems.

3.

There were no liquid release tanks or gas decay tanks which exceeded the limits addressed in the ODCM-RETS.

4.

There were no abnormal liquid releases in 2009 resulting in offsite discharge.

On 6/30/09, a spill of U2 secondary water containing tritium occurred when a sump overflowed. The water flowed out of the Condensate Polisher Room to the ground and to a storm sewer. The storm sewer water was immediately pumped back to the plant drain system and sampling was initiated at downstream points to ensure that the contaminated water did not leave site.

One abnormal gaseous release occurred in 2009 and is described below.

On July 30, 2009, Unit 2 tripped and steam containing tritium was released to the atmosphere through the steam generator power operated relief valves (PORVs). The plant performed as designed and when these valves opened and intermittently as the plant was cooled down. The steam release continued periodically for approximately 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> until normal cooling was restored to the unit. At the time of this release, Unit 2 secondary tritium concentration was 3.86E-5 ýiCi/g. A conservative release permit was performed in the Radioactive Effluent Tracking and Dose Assessment Software (RETDAS). Permit #2010007 was used to calculate offsite dose from the release. The calculated dose was insignificant.

5.

The following effluent monitoring instruments exceeded their specified inoperability time.

OF-WX001 (Liquid Radwaste Effluent Line Loop WX001) exceeded its specified inoperability time on 4/24/07. At that time, required surveillances for this effluent instrument were taken to "suspend" and were not performed because this effluent flow path was no longer in use at Braidwood Station. The instrument continues to be inoperable and no liquid releases have taken place through this release path during the time of inoperability. A design change and modification to this flow path are in progress. Required surveillances will be performed prior to this flow path being put back in service.

One liquid effluent radiation instrument was inoperable beyond the time allowed in the ODCM. On 10/26/09, ORE-PROO1, Liquid Radwaste Effluent Line Radiation Monitor, was declared inoperable and entered the 14 day time clock established in the ODCM. Liquid radwaste releases were performed within the 14 days using the guidance established in the ODCM and station Operating procedures. ORE-PRO01 was not declared operable by the end of the 14 day period on 11/8/09, and liquid radwaste releases were suspended until the monitor was declared operable. Work was completed and the monitor was declared operable on 11/10/09.

6.

No changes were made to the ODCM in 2009.

7.

NUREG-0543, Methods for Demonstrating LWR Compliance with the EPA Uranium Fuel Cycle Standard (40 CFR Part 190) states in section IV, "As long as a nuclear plant site operates at a level below the Appendix I reporting requirements, no extra analysis is required to demonstrate compliance with the 40 CFR Part 190." The organ and whole body doses reported on pages 28 through 47 are determined using 10 CFR 50 Appendix I methodology. The doses are below the limits of Appendix I.
