BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2012 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

General Overview/Discussion This report quantifies the radioactive gaseous, liquid, solid radwaste releases, and summarizes the local meteorological data for the period from January 01, 2012 through December 31, 2012. This report has been prepared utilizing the methodology and parameters specified in the calculation of offsite doses resulting from radioactive gaseous and liquid effluents found in Braidwood's Offsite Dose Calculation Manual (ODCM). It has been formatted consistent with Exelon Procedure CY-AA-1 70-2000 and exceeds the requirements specified in Regulatory Guide 1.21 revision 1, "MEASURING, EVALUATING, AND REPORTING RADIOACTIVITY IN SOLID WASTES AND RELEASES OF RADIOACTIVE MATERIALS IN LIQUID AND GASEOUS EFFLUENTS FROM LIGHT-WATER-COOLED NUCLEAR POWER PLANTS."

The quantity of radioactive material released from Braidwood Nuclear Power Plant was determined from in-house and vendor laboratory analysis of continuous on-line sampling media and batch sample media from all ODCM specified effluent pathways. These pathways include the Unit 1 and 2 Station Vent Stacks, Exelon Pond remediation, Turbine Building Remediation, Vacuum Breaker number one remediation, Condensate Polisher Sump, Waste Water Treatment facility, and Circulating Water Blowdown.

The volume and quantity of radioactive waste shipped offsite from Braidwood Nuclear Power Plant for processing and disposal were determined from data maintained in the radwaste shipping database.

Radwaste processed for shipment was in accordance with Exelon procedure RW-AA-100, "PROCESS CONTROL PROGRAM FOR RADIOACTIVE WASTES" and consistent with the UFSAR.

Meteorological data was obtained from the 320 foot meteorological tower located on the Braidwood Station premises.

Gaseous Effluents Gaseous radioactive releases for the 2012 timeframe are captured in the tables titled, "Summation of All Releases" for Unit 1 and 2, respectively. Radioactive noble gases released for the timeframe totaled 8.16E-01 Curies. Releases of radioiodines and particulates with a half-life greater than eight days totaled 1.58E-03 Curies. Gaseous tritium releases totaled 5.71 E+02 Curies. Gaseous C-14 was calculated to total 8.31 E+00 Curies. No gross alpha was detected in gaseous effluents.

Noble gases released in gaseous effluents resulted in a maximum total body dose of 8.82E-06 mrad, with a corresponding skin dose of 3.44E-05 mrad. The release of radioactive particulates, C-14, tritium, and radioiodines in gaseous effluents during the reporting period resulted in a total body dose to the maximally exposed hypothetical individual of 5.74E-01 mrem. The maximum hypothetical dose to any organ from radioactive particulates, C-14, tritium, and radioiodines was 2.23E+00 mrem.

Liquid Effluents Liquid radioactive releases for the 2012 timeframe are captured in the table titled, "Liquid Effluents Supplemental Release Information" and in Appendix C, "Unit Specific Annual Effluent Summaries." Ninety-six liquid batch releases occurred during the reporting period. Additionally, radioactive liquid effluents were continually being released through Circulating Water Blowdown. These discharges contained 2.58E+03 Curies of tritium and 1.08E+00 Curies of fission and activation products. The resultant maximum total body dose was 4.82E-02 mrem, with a corresponding organ dose of 6.86E-02 mrem.

Meteorological Data The Braidwood Station meteorological monitoring program produced 52,408 hours0.00472 days 0.113 hours 6.746032e-4 weeks 1.55244e-4 months of valid data out of a possible 52,704 parameter hours during 2012 (366 days x 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s/day x 6 measured priority parameters),

which represents an overall data recovery rate of 99.4%. Priority parameters are all parameters except dew point temperature and precipitation. For the year, winds measured at 34 ft. most frequently came from the South (10.00%) and fell into the 3.6 - 7.5 mph wind speed class (41.78%). Calms (wind speeds at or below the sensor threshold) were measured 0.12% of the time and speeds greater than 24.5 mph were measured 0.15% of the time. Stability based on the 199 - 30 ft. differential temperature most frequently fell into the neutral classification (35.77%).

Offsite Ambient Radiation Measurements It is estimated that the average radiation dose received by an individual in the United States is about 360 mrem/yr and that nuclear power stations account for less than two parts in a thousand of this radiation.

These figures are based on data in Table 8.1 of NCRP 93. The table includes the following data:

Source Average Individual Dose (mrem/yr)

Natural sources (average in U.S.)

300 Medical (whole-body equivalent) 53 Nuclear fuel cycle 0.05 Other

-7 Total About 360 The radiological effects of nuclear power station operation on the environment are characterized as "usually so small that they are masked by normal fluctuations in natural background sources and by the normal uncertainties of the measurement process." Review of the Braidwood Optically Stimulated Luminescent Dosimetry (OSLD) data yielded no measurable increase above the normal fluctuation in natural background levels.

Radioactive Solid Waste Disposal Radioactive wastes shipped offsite are captured in the table titled, "Solid Wastes Shipped Offsite for Burial or Disposal (Not irradiated fuel)." Approximately 781 cubic meters of solid waste was shipped offsite containing approximately 39 Curies during the 2012 reporting period.

Average Energy The ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/yr to the total body, and less than or equal to 3,000 mrem/yr to the skin. Therefore, the average beta and gamma energies (P-) for gaseous effluents as described in Regulatory Guide 1.21 are not applicable.

4.

Measurements and Approximations of Total Radioactivity

a.

Fission and activation gases:

Before being discharged, containment batch releases are analyzed for noble gas and tritium via gamma spectroscopy and liquid scintillation, respectively. Gaseous decay tanks are analyzed for noble gases before being discharged via gamma spectroscopy. 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 radioiodines and particulates. These samples are pulled every seven days and analyzed via gamma spectroscopy.

Noble gas samples are pulled and analyzed weekly by gamma spectroscopy. The average flow at the release points and nuclide specific activity concentrations are used to calculate the activity 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.OOE-5 mrem) in offsite dose.

b.

lodines:

Radioiodines in the Auxiliary Building ventilation exhaust system are continually being collected via activated charcoal cartridges in the diverted sample process flow. The iodine cartridges are pulled weekly and analyzed via gamma spectroscopy. Radioiodine concentrations greater than the LLD are multiplied by the volume of air discharged during the sampling timeframe.

Radioiodines are analyzed in liquid effluent streams through performance of batch release tank grab samples and weekly liquid effluent composite samples. The analyses are performed via gamma spectroscopy.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units. Effluents that are unit specific are assigned to the appropriate unit.

5 of 124

c.

Particulates, half-lives > 8 days:

Particulates in the Auxiliary Building ventilation exhaust system are continually being collected via filter media in the diverted sample process flow. Particulate filter media are pulled weekly and analyzed via gamma spectroscopy. Particulate concentrations greater than LLD are multiplied by the volume of air discharged during the sampling timeframe. A composite sample is created from 3 month's particulate sample media for Sr-89/90, Fe-55, and gross alpha analysis by an offsite vendor. The vendor supplied data are utilized in conjunction with the volume of air released through the Auxiliary Building ventilation to quantify Sr-89/90, Fe-55, and gross alpha releases.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units. Effluents that are unit specific are assigned to the appropriate unit.

d.

Liquid effluents:

Liquid effluents are categorized as either batch release or continuous release. All liquid releases are analyzed for principal gamma emitters, radioiodines, dissolved and entrained gases, gross alpha, and tritium onsite via gamma spectroscopy, gas flow proportional counting, or liquid scintillation, as appropriate. An offsite laboratory analyzes liquid composites for Sr-89/90 and Fe-55. Vendor results are applied to the applicable volume of liquids discharged during the timeframe. Volumes and activities of effluents discharged from systems or locations are divided between both units.

e.

Gross alpha Gross alpha is analyzed in both the gaseous and liquid effluent pathways. Weekly gaseous particulate media is composited for offsite vendor analysis. Gross alpha activity greater than vendor LLD values are assigned to the applicable timeframe and gaseous volume released. Liquid effluent gross alpha analysis is performed through compositing monthly discharges and gas flow proportional counting.

f.

Carbon-14 Carbon-14 is assessed for continuous gaseous effluents through the use of Electric Power Research Institute's (EPRI) industry accepted production mechanism and production rate study 1021106. C-14 production is a function of each unit's full power operation and gaseous volume released. C-14 is not evaluated through laboratory sample analysis.

g.

Estimated Total Error Present Estimated total error is calculated periodically and communicated as part of the Effluent and Waste Disposal Summaries.

h.

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.

ODCM Revisions The ODCM was revised in 2012 to change all the references of Thermoluminescent Dosimeters (TLDs) to "dosimeter". The change to the ODCM was made as part of the change from TLD technology to Optically Stimulated Luminescent Dosimetry (OSLD). The change to OSLD technology was driven by OSLDs dynamic energy response, increased sensitivity, environmental integrity, and its repeat analysis capabilities. CY-BR-170-301 revision 7 (ODCM) is included as a searchable text document on an included CD due to the size of the Portable Document Format (PDF).

C. Changes to the Process Control Program Exelon Exelon procedure RW-AA-100 governs the radioactive waste process control program. The process control program establishes parameters which provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by in-plant waste process systems on-site or by on-site vendor supplied waste processing systems, meet the acceptance criteria to a Licensed Burial Facility, as required by 10CFR Part 20, 10CFR Part 61, 10CFR Part 71, 49CFR Parts 171-172, 'Technical Position on Waste Form (Revision 1)" [1/91], "Low-Level Waste Licensing Branch Technical Position on Radioactive Waste Classification" [5/83], and the Station Technical Specifications, as applicable. The process control program was revised in 2012. The substantial changes to the PCP allowed for the offsite storage of waste and clarified the storage of activated hardware. The first change created the option to store waste at Exelon sites that had greater storage capacity, provided the receiving plant had formal NRC approval. The second change created the option to store waste at an offsite vendor, provided that the waste met the vendor's waste acceptance criteria. The final change clarified the storage of activated hardware. Numerous non-substantial changes were made throughout the document to correct grammatical errors and to improve document readability. The implemented PCP, RW-AA-1 00, has been included in Attachment 2.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2012 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

Instrument Issues On 3/19/12, the weekly ODCM Exelon Pond compositor did not have the needed two liters of sample to perform the required analysis. Remediation had ceased within that sampling timeframe due to low Exelon Pond level. Approximately 2,836,451 gallons of Exelon Pond water were released to Circulating Water Blowdown prior to its securement. Water from the Exelon Pond had been trending less than 200 pCi/L tritium for the entirety of 2012 as monitored for RGPP.

Additionally, remediated Exelon Pond water was composited downstream as part of Circulating Water Blowdown. This issue was entered into the Corrective Action Program as IR 1342983.

On 4/9/12, it was found that the Exelon Pond composite sample jug was without sample. A composited sample was not obtained from the time period 4/2/12 10:50 through 4/9/12 13:40. The Exelon Pond remediates at a rate of 1000 gallons per minute. The flow totalizer indicated a release of 50,000 gallons, therefore, the pump would have been running for approximately 50 minutes. The compositor is programmed to take a sample of the process flow every 90 minutes. The Exelon Pond pump was not running long enough to initiate the first sample. Water from the Exelon Pond had been trending less than 200 pCi/L tritium for the entirety of 2012 as monitored for RGPP.

Additionally, remediated Exelon Pond water was composited downstream as part of Circulating Water Blowdown. This issue was entered into the Corrective Action Program as IR 1351826.

On 4/15/12, the weekly ODCM Exelon Pond compositor did not have the needed two liters of sample to perform the required analysis. Exelon Pond remediation was terminated until the solenoid operated sample valve was repaired. Water from the Exelon Pond had been trending less than 200 pCi/L tritium for the entirety of 2012 as monitored for RGPP. Additionally, remediated Exelon Pond water was composited downstream as part of Circulating Water Blowdown. This issue was entered into the Corrective Action Program as IR 1354481.

During Al R1 6, an LCO was entered for a planned bus outage affecting the 1 PR28J and 1 PR30J gaseous effluent monitors. Radiation Protection established the requisite sampling for the effluent stream to ensure continuous sampling. On 4/27/12 it was found that the compensatory sampling was inoperable. The portable air sampling pump's fuse had blown at some time between 4/27/12 00:00 and 4/27/12 08:00. The sample pump was replaced and functioned without incident afterward. ODCM Table 12.2-3 note 40 requires continuous collection of particulate and iodine samples via alternate sampling equipment when the 1 PR28J is inoperable. Particulate and iodine concentrations were evaluated during the timeframe before and timeframe after the sampling pump failure. Particulate and iodine values were less than LLD for those analytes. There were no unusual plant evolutions occurring during that timeframe that would have increased particulate or iodine concentrations. This issue was entered into the Corrective Action Program as IR 1359736.

On 5/24/12, the CWBD compositor was found to not be working. The compositor was promptly repaired and compensatory grab sampling was instituted. This issue was entered into the Corrective Action Program as IR 1370433.

On 6/3/12, the 14 day time clock associated with OPR02J operability expired. Releases from waste gas release tanks ceased after the expiration of the time clock. Decontamination of the OPR02J was required to return the instrument to operable status. This issue was entered into the Corrective Action Program as IR 1373813.

On 6/27/12, a chemistry technician identified that the height of the iodine cartridges used in the Station Vent Stack 1/2PR29J process radiation monitors were greater than those used in the 1/2PR28J process radiation monitors. The calibrated geometry used for the 1/2PR28J had been used interchangeably for both iodine cartridges for many years. A calibration source was created for the taller iodine cartridge for comparison to the historically used geometry. An 11.6% average disparity across the energy range of interest was identified between the two geometries. A calibration geometry was created for the taller iodine cartridge and is currently being utilized.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2012 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

The 1/2PR29J process radiation monitors serve as the back-up to the 1/2PR28J process radiation monitors. Iodine results from 1/2PR29J instruments are infrequently used for ODCM dose calculations. In 2012, the 1 PR29J sample data was used for ODCM dose calculations for four weeks during the year. Each of those weeks' iodine concentrations were less than the lower level of detection. 2PR29J sample data was used for a period of two weeks during the year. 1-131 was identified on one of the samples corresponding to an effluent concentration of 8.225E-14 uCi/cc.

Increasing the effluent concentration to 9.179E-14 uCi/cc would have increased the dose to the thyroid of the maximally exposed individual by 2.OOE-06 mrem. This issue was entered into the Corrective Action Program as IR 1404278.

On 7/10/12, the weekly ODCM Exelon Pond compositor did not have the needed two liters of sample to perform the required analysis. The Exelon Pond pump was shutdown on 7/3/12. The last sample obtained from the Exelon pond pump compositor was on 7/2/12. The Exelon pond pump ran for approximately one day before being shut down for which there was insufficient sample to meet the procedurally required two liter minimum sample required for analysis. Water from the Exelon Pond had been trending less than 200 pCi/L tritium for the entirety of 2012 as monitored for RGPP. Additionally, remediated Exelon Pond water was composited downstream as part of Circulating Water Blowdown. This issue was entered into the Corrective Action Program as IR 1387611.

On 9/17/12, the Waste Water Treatment compositor was found to be off. Upon investigation it was determined that the ground fault circuit interrupter (GFCI) had tripped. The GFCI was reset and the sampling program resumed. It is unknown when the sampler stopped compositing, however, there was adequate sample in the polyethylene jug for analysis. This issue was entered into the Corrective Action Program as IR 1414098.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2011 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

ATTACHMENT 1 ERRATA CORRECTIONS FROM 2011 REPORT 112 of 124

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2012 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

Errata for Previous Annual Radioactive Effluent Release Reports Improvements in nuclear power plant effluent management practices have resulted in a decrease in radiological effluent concentrations and a change in the distribution of gaseous radionuclides released to the environment. In Pressurized Water Reactors (PWRs), such as Braidwood, Carbon-14 (C-14) is produced in the reactor and released with gaseous effluents through the plant vent stacks unmitigated by the effluent treatment process. At many plants, C-14 may not have been a dose significant radionuclide, however, as effluent activities have been reduced over the years, C-14's calculated relative abundance has increased. Regulatory Guide 1.21 Revision 2 indicates that the C-14 discharge can be estimated by sample measurements or by use of a normalized C-14 source term and scaling factors based on power generation. The NRC has provided direction to all U.S. nuclear stations that C-14 must be reported in the ARERR. Braidwood's C-14 release (4.45 curies per unit) was conservatively estimated based on Electric Power Research Institute (EPRI)

Technical Report 1021106 and added to gaseous effluents as a continuous release through the plant vent stacks. As a result, the organ dose to the maximum exposed individual increased substantially, but the resultant annual dose remains below 1 mrem per year against an annual regulatory limit of 15 mrem per year organ dose. The C-14 release and dose data can be viewed in the included tables.

C-14 is primarily released as a gas in the form of carbon dioxide. The gaseous effluent tracking software that is utilized by Braidwood had been set up to characterize C-14 as a particulate in 2011.

While the software correctly calculated dose for the C-14 emissions, the fraction of particulates released by the station grew significantly. This method of accounting for C-14 in the "particulate" category proved troublesome as Braidwood Station appeared to be an industry outlier for the quantity of particulates released in 2011. Most stations were placing C-14 in the "other" category. A request was made to resubmit the relevant 2011 C-14 effluent data to place the determined activities in the "other" category. The dose associated with the emissions does not require revision as the software calculated it correctly. The Errata is being submitted to allow effective effluent comparisons across the industry. IR 1465929 was entered into the Corrective Action Program to document the issue.

The following changes are the 2011 errata submission:

2011 1st quarter U-1 particulates (>8 day half life) = 0 Ci U-2 particulates (>8 day half life) = 1.61 E-06 Ci 2011 2nd quarter U-1 particulates (>8 day half life) = 0 Ci U-2 particulates (>8 day half life) = 1.96E-09 Ci 2011 3rd quarter U-1 particulates (>8 day half life) = 3.50E-06 Ci U-2 particulates (>8 day half life) = 0 Ci 2011 4th quarter U-1 particulates (>8 day half life) = 0 Ci U-2 particulates (>8 day half life) = 0 Ci 113 of 124
