BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2014 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, 2014 through December 31, 2014. 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-170-2000 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 Slowdown.

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 2014 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 3.42E-01 Curies. Releases of radioiodines and particulates with a half-life greater than eight days totaled 3.88E-04 Curies. Gaseous tritium releases totaled 2. 71 E+02 Curies. Gaseous C-14 was calculated to total 8.61 E+OO Curies. No gross alpha was detected in gaseous effluents.

Noble gases released in gaseous effluents resulted in a maximum total body dose of 2.36E-05 mrem, with a corresponding skin dose of 1. 71 E-03 mrem. 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 5.25E-01 mrem. The maximum hypothetical dose to any organ from radioactive particulates, C-14, tritium, and radioiodines was 2.31 E+OO mrem.

Liquid Effluents Liquid radioactive releases for the 2014 timeframe are captured in the table titled, "Liquid Effluents Supplemental Release Information" and in Appendix C, "Unit Specific Annual Effluent Summaries." One hundred and four (104) liquid batch releases occurred during the reporting period. Additionally, radioactive liquid effluents were continually being released through Circulating Water Slowdown. These discharges contained 3.01 E+03 Curies of tritium and 9.48E-02 Curies of fission and activation products. The resultant maximum total body dose was 4.26E-02 mrem, with a corresponding organ dose of 8.60E-02 mrem.

Page 2 of 165

40CFR190 Compliance The Braidwood ODCM defines the total dose for the uranium fuel cycle as the sum of doses due to radioactivity in airborne and liquid effluents and the doses due to direct radiation from contained sources at the nuclear power station. The total dose, Dror, in the unrestricted area to a member of the public due to Plant operations is given by** Dror = DEx + Du.qa1

+ DN!VG a1 Where:

Dror Total Dose to Member of Public [mrem]

Total off-site dose to a member of public due to plant operations.

DEx Total ExternalTotal Body Dose [mrem]

Total body dose due to external exposure to noble gases, N-16 skyshine and on-site storage facilities.

D~~q Liquid Effluent Dose [mrem]

Dose due to liquid effluents to age group a and organ j. The age group and organ with the highest dose from liquid effluents is used.

D~tc Non-Noble Gaseous Effluent Dose [mrem]

Dose due to non-noble gaseous effluents to age group a and organ j. The age group and organ with the highest dose from non-noble gas effluents is used.

Exposures measured on the Independent Spent Fuel Storage Installation (ISFSI) and Onsite Steam Generator Storage Facility (OSGSF) dosimeters are statistically indiscernible from natural background. N-16 skyshine is not applicable to Pressurized Water Reactors. The resultant 40CFR190 dose calculated for a member of the public is 2.88E+OO mrem.

Meteorological Data The Braidwood Station meteorological monitoring program produced 52,433 hours0.00501 days 0.12 hours 7.159392e-4 weeks 1.647565e-4 months of valid data out of a possible 52,560 parameter hours during 2014 (365 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 99.8%. Priority parameters are all parameters except dew point temperature and precipitation. For the year, winds measured at 34 ft. most frequently came from the West-Northwest (10.25%) and fell into the 3.6 - 7.5 mph wind speed class (41.34%). Calms (wind speeds at or below the sensor threshold) were measured 0.02% of the time and speeds greater than 24.5 mph were measured 0.04% of the time. Stability based on the 199 - 30 ft. differential temperature most frequently fell into the neutral classification (40.33%).

The following are the maximum annual calculated cumulative offsite doses resulting from Braidwood Station airborne releases in 2014 based on concurrent meteorological data:

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 About360 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 (OSLO) 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 8.58E+02 cubic meters of solid waste was shipped offsite containing approximately 2.22E+01 Curies during the 2014 reporting period.

b. Iodine: 10CFR20 Appendix B Table 2

c. Particulates: 10CFR20 Appendix B Table 2

d. Liquid Effluents: 10 X 10CFR20 Appendix B Table 2

3. 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 (E) 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 via gamma spectroscopy. 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.

b. Iodines:

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 of the liquid samples.

Page 7 of 165

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.

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. Tritium:

Before being discharged, containment batch releases are analyzed for tritium via a liquid scintillation counter (LSC). Tritium is sampled using a flow-through bubbler system.

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 monitored for tritium using a flow-through bubbler system. Tritium is sampled every seven days and analyzed by LSC.

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 (1.00E-5 mrem) in offsite dose.

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 lnstitute's (EPRI) industry accepted production mechanism and production rate Page 8 of 165

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. 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.

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

i. 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.

B. Irradiated Fuel Shipments (disposition)

No irradiated fuel shipments for January through December, 2014.

C. Changes to the Process Control Program (PCP)

The Process Control Program was revised in 2014. On 8/11/2014, RW-AA-100, Revision 10, "Process Control Program of Radioactive Wastes" was implemented. The substantial changes to the PCP allowed for concentration averaging and encapsulation of radioactive wastes in accordance with the NRC's Branch Technical Position of Concentration Averaging and Encapsulation-January 1995. Further, the revision allowed for blending of routine low level radioactive waste (LLRW) such as resins and filter media in accordance with the NRC's Branch Technical Position on Concentration Averaging and Encapsulation as further clarified in Commission Paper (SECY) 2010-0043. Predicted releases of radioactive materials and expected maximum exposures did not differ from the implementation of these changes to the PCP. The changes did not reduce the overall conformance of solidified waste product to the existing criteria for solid wastes. The revised PCP has been included in Attachment 2.

Instrument and sampling Issues

1. On 09/02/2014 while preparing the shipment of Unit 1 and Unit 2 PR28J and PR29J air particulate filter samples, it was discovered that a single filter paper from Unit 2 was missing. The missing filter was used to sample Unit 2 effluents during the time period from 05/14/2014 through 05/2112014. Immediately upon learning of the missing sample, a thorough search was conducted of the storage container that housed the samples during the second quarter 2014 prior to shipment. A review of the gamma spectroscopy analysis performed on the missing sample at Briadwood prior to shipment indicated that the particulate nuclides were all less than LLD. Based on sampling history and process knowledge of this location, it is reasonable to assume the missing sample was void of difficult to measure (DTM) isotopes. This issue was documented as issue report IR 1699084.

2. On 07/28/2014, it was found that the flow totalizer for remediation well number 7 (RW-7) for vacuum breaker number one (VB-1) wasn't working properly. The remediation pump was running and water could be collected from the compositor, but the flow totalizer was not measuring flow. This issue is included in the 2014 ARERR to document that water from RW-7 was being composited, collected and analyzed even though the flow totalizer was not accurately measuring flow. Even though a total discharge volume could not be calculated due to the malfunctioning totalizer, an estimated throughput could be calculated based on time the pump had been running and the design discharge flowrate (i.e. 45 gallons per minute). An issue report was written to document this in IR 1686320.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2014 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

During a review of the 2013 ARERR, it was identified that the implementation date in the footer of every page of ODCM Revision 8 did not correctly reflect the implementation date of "July 2013." A corrected record is needed for the ODCM (CY-BR-170-301 Rev. 8) to correct the implementation date. This is an administrative change to Revision 8. There are no technical changes being made to the ODCM. Records Management has been contacted for concurrence. This issue was documented in IR 1653615.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2014 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

Braidwood Station's Process Control Program (PCP) is managed by procedure RW-AA-100, "Process Control Program of Radioactive Wastes." The purpose of the Process Control Program (PCP) is to:

1. Establish the process and boundary conditions for the preparation of specific procedures for processing, sampling, analysis, packaging, storage, and shipment of solid radwaste in accordance with local, state, and federal requirements. (CM-1)

2. Establish parameters which will provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by the 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.

3. Provide reasonable assurance that waste placed in "on-site storage" meets the requirements as addressed within the Safety Analysis Reports for the low level radwaste storage facilities for dry and/or processed wet waste.

The PCP was revised on 8/11/2014 with the issuance of RW-AA-100, Revision 10.

1. 1 Tile purpose of the Process control Program {PCP) is to:

t . 1. 1. Establish the process and boundary conditions for the preparation of specific procedures for processing, sampling, analysis, packaging, storage, and shipment of solid radwaste in accordance with local, state, and federal requirements. (CM-1)

1. 1.2. Establish parameters which will provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by the 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.

Waste Form (Revision 1 [1191}, "Low-Level Waste Licensing Branch Technical Position on Radioactive Waste Classification- [5183], and the station Technical Specifications, as applicable.

1. 1.3': Provide reasonable assurance that waste placed in "on-site storage~ meets the requirements as addressed within the Safety Analysis Reports for the tow level radwaste storage facilities for dry and/or processed wet waste.

2. TERMS ANO DEFINITIONS

2. l Process Control Program <PCP}: The program which contains the current formulas, sampling, analysis, tests, and determinations to be made to ensure that processing and packaging of solid radioactive waste based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure the waste meets the stabilization criteria specified in 10CFR Parts 20, 61 and 71, state regulations, and burtal site requirements.

2.2. Solidification

Liquid waste processed to either an unstable or stable form per 10CFR61 requirements. waste solidified does not have to meet the 300-year free standing monolith criteria. Approved formulas. samples and tests do not have to meet NRC approval for wastes solidified in a container meeting stability criteria (e.g.

High Integrity Container}.

2.3. Stabilization

Liquid waste processed to a *stable state" per 10CFR61 Requirements. Established formulas, samples, and tests shall be approved by the NRC in order to meet solidification "stabilization" criteria. This processing method is currently not available, because the NRC recognizes that waste packed in a High Integrity Container meets the 300-year stabilization criteria. In the event that this processing method becomes an acceptable method, then the NRC shall approve the stabilization formulas, samples. tests, etc.

RW-AA-100 Revision 10 Page2of 12 2.4. Solidification Media: An approved media (e.g. Barnwell - vinyl ester styrene, cement, bitumen) when waste containing nuclides with greater than 5-year half lives is solidified in a container with activity greater than *1 micro curie/cc. Waste solidified in a HIC is approved by the commission meeting the 10CFR61 stabilization criteria, fnciuding 1% tree standing liquids by volume when the waste is packaged to a

stable* form and_:::. 0.5% when waste is packaged to an "unstable* form. The formulas, sampling, analysis. and test do not require NRC approval, because the HIC meets the stability criteria.

2.4.1 Solidification to an unstable or stable state ts performed by vendors, when applicable. liquid waste solidified to meet stabilization criteria (10CFR61 and 01-91 Branch Technical Requirements) shall have documentation available that demonstrates that the process is approved by the NRC or disposal facility.

2.5. Dewatering

The process of removing fluids from liquid waste streams to produce a waste form that meets the requirements of 10CFR Part 61 and applicable burial site criteria, .:::-.0.5% by volume when the waste is packaged to an "unstable" state. or

~1% by volume when the waste is packaged to a wstable" form.

2.6. High Integrity Container CHIC): A disposable container that is approved to the Requirements of 10CFR61 The use of HIC's is an alternative to solidification or encapsulation in a steel container to meet burial stability. HIC's are used to paekage dewatered liquid wastes, (e.g. filter cartridges. filter media, resin. sludges. etc), or dry active waste.

2.7. Liquid Waste Processing Systems: In-plant or vendor supplied processing systems consisting of equipment utilized for evaporation, filtration, demineralization, dewatering, compression dewatering, solidification, or reverse osmosis (RO) for the treatment of liquid wastes (such as Floor Drains, Chemical Drains and Equipment Drain inputs).

2.8. Incineration. RVR. and/or Glass Vitrification of Liquid or Solid: Dry or wet waste processed via incineration and/or thermal processing where the volume is reduced by thermal means meets 10CFR61 requirements.

2.9. Compaction

When dry wastes such as paper, wood, plastic, cardboard, incinerator ash, and etc. are volume reduced through the use of a compactor.

RW-AA-100 Revision 10 Page 3of 12 2.1 O. Waste Streams: Consist of but are not limited to Filter media (powdered, bead resin and fiber),

Filter cartridges, Pre-coat body feed material, Contaminated charcoal.

Fuel pool activated hardware, Oil Dry absorbent material added to a container to absorb liquids Fuel Pool Crud Sump and tank sludges, High activity filter cartridges, Concentrated liquids, Contaminated waste oil, Dried sewage or wastewater plant waste, Dry Active Waste (DAW): Waste such as filters, air filters, low activity cartridge filters, paper, wood, glass, plastic, cardboard, hoses, cloth, and metals, etc, which have become contaminated as a consequence of normal operating, housekeeping and maintenance activities.

Other radioactive waste generated from cleanup of inadvertent contamination.

2.11. Concentration Averaging: Concentration averaging is either: a) the mathematical averaging of waste concentrations, based on the size, geometry, type of radioactive emission, and observed dose rates, orb) the combining of radioactive components in a single container and how their radioactivity may be averaged over the volume of the container. Concentration averaging ls subject to constraints identified in the NRC's Branch Technical Position on Concentration Averaging and Encapsulation and may also be constrained by Agreement States or Disposal Facilities.

2.12. Encapsulation: Encapsulation is the surrounding of a radioactive source or component with a nonradioactive material. Encapsulation involves a radioactive core surrounded by a non-radioactive matrix.

2.13. Blending: The intentional mixing of different, but miscible waste streams (such as resins, filter media, etc.) from different batches or systems for the purpose of operational efficiency or AlARA. Blending applies to LLRW streams only. The addition of non-radioactive materials or fillers is not considered blending.

3. RESPONSIBILITIES 3.1. Implementation of this Process Control Program (PCP) is described in procedures at each station and is the responsibility of the each site to implement.
