Preface BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2022 UNIT 1, UNIT 2 and ISFSI (Docket Numbers 50-456, 50-457 and 72-73)

The following sections of the preface are meant to help define key concepts, provide clarity. and give context to the readers of this report Annual Reports The Nuclear Regulatory Commission (NRC) is the federal agency who has the role to protect public health and safety through the development of regulations governing nuclear power reactors and ensuring their compliance. As part of the many commitments Nuclear Power Plants have to the NRC to ensure this safety, they provide two reports annually to specifically address how the station's operation impacts the environment of local communities. The NRC then reviews these reports and makes them available to the public. The names of the reports are the Annual Radioactive Effluent Release Report (ARERR) and the Annual Radiological Environmental Operating Report (AREOR).

The ARERR reports the results of the sampling from the effluent release paths at the station analyzed for radioactivity. An effluent is a liquid or gaseous waste containing plant-related radioactive material emitted at the boundary of the facility.

The AREOR reports the results of the samples obtained in the environment surrounding the station.

Environmental samples include air, water, vegetation, and other sample types that are identified as potential pathways radioactivity can reach humans Graphic 1. Examples of Gaseous and Liquid Effluent Pathways v,:ater CT Grcund:,ati.:<

Graphic 1 demonstrates some potential exposure pathways from Braidwood Nuclear Power Station. The ARERR and AREOR together ensure Nuclear Power Plants are operating in a manner that is within established regulatory commitments meant to adequately protect the public Page 2 of 95

Understanding Radiation Generally radiation is defined as emitted energy in the form of waves or particles. If radiation has enough energy to displace electrons from an atom it is termed "ionizing", otherwise it is "non-ionizing". Non-Ionizing radiation includes light, heat given off from a stove, radiowaves and microwaves. Ionizing radiation occurs in atoms, particles too small for the eye to see. So, what are atoms and how does radiation come from them?

Electron The number of protons in an atom determines the element. For example, a hydrogen atom will always have one proton while an oxygen atom will always have eight protons. The protons are clustered with the neutrons forming the nucleus at the center of the atom. Orbiting around the nucleus are the relatively small electrons Isotopes are atoms that have the same number of protons but different numbers of neutrons. Different isotopes of an element will all have the same chemical properties and many isotopes are radioactive while other isotopes are not radioactive. A radioactive isotope can emit radiation because it contains excess energy in its nucleus.

Radioactive atoms and isotopes are also referred to as radionuclides and radioisotopes.

There are two basic ways that radionuclides are produced at a nuclear power plant. The first is fission, which creates radionucides that are called fission products. Fission occurs when a very large atom, such as uranium-235 (U-235) or plutonium-239 (Pu-239), absorbs a neutron into its nucleus making the atom unstable. The unstable atom can then split into smaller atoms. When fission occurs there is a large amount of energy released, in the form of heat. A nuclear power plant uses the heat generated to boil water that spins turbines to produce electricity.

The second way a radionuclide is produced at a nuclear power plant is through a process called activation Radionuclides produced in this method are termed activation products Pure water that passes over the fissioning atoms is used to cool the reactor and also produce steam to turn the turbines. Although this water is considered to be very pure, there are always some contaminants within the water from material used in the plant's construction and operation. These contaminants are exposed to the fission process and may become activation products. The atoms in the water itself can also become activated and create radionuclides.

Over time, radioactive atoms will reach a stable state and no longer be radioactive. To do this they must release their excess energy. This release of excess energy is called radioactive decay. The time it takes for a radionuclide to become stable is measured in units called half-lives A half-life is the amount of time it takes for half of the original radioactivity to decay. Each radionuclide has a specific half-life Some half-lives can be very long and measured in years while others may be very short and measured in seconds.

Graphic 4. Radioactive Decay Half-Life Half-I The amount of time it takes for half of the original radioactivity to decay In the annual reports you will see both man made and naturally ocurring radionuclides listed, for example potassium-40 (K-40, natural) and cobalt-60 (Co-60, man-made). We are mostly concerned about man-made radionuclides because they can be produced as by-products when generating electricity at a nuclear power plant It is important to note that there are also other ways man-made radionuclides are produced, such as detonating nuclear weapons. Weapons testing has deposited some of the same man-made radionuclides into the environment as those generated by nuclear power, and some are still present today because of long half-lives.

Measuring Radiation There are four different but interrelated units for measuring radioactivity, exposure, absorbed dose, and dose equivalent. Together, they are used to scientifically report the amount of radiation and its effects on humans.

Radioactivity refers to the amount of ionizing radiation released by a material. The units of measure for radioactivity used within the AREOR and AR ERR are the Curie (Ci) Small fractions of the Ci often have a prefix, such as the microcurie (µCi), which means 1/1,000,000 of a Curie.

Exposure describes the amount of radiation traveling through the air. The units of measure for exposure used within the AREOR and ARERR are the Roentgen (R). Traditionally direct radiation monitors placed around the site are measured milliRoentgen (mR), 1/1,000 of one R.

Absorbed dose describes the amount of radiation absorbed by an object or person. The units of measure for absorbed dose used within the AREOR and AR ERR are the rad. Noble gas air doses are reported by the site are measured in millirad (mrad), 1/1,000 of one rad Dose equivalent (or effective dose) combines the amount of radiation absorbed and the health effects of that type of radiation. The units used within the AREOR and AR ERR are the Roentgen equivalent man (rem). Regulations require doses to the whole body, specific organ, and direct radiation to be reported in millirem (mrem), 1/1,000 of one rem.

Sources of Radiation People are exposed to radiation every day of their lives and have been since the dawn of mankind. Some of this radiation is naturally occurring while some is man-made. There are many factors that will determine the amount of radiation individuals will be exposed to such as where they live, medical treatments, etc. The average person in the United States is exposed to approximately 620 mrem each year. Half of this exposure, 310 mrem, comes from natural sources and the other half, 310 mrem, from man-made sources. Graphic 5 shows what the typical sources of radiation are for an individual over a calendar year:

Full report is available on the NCRPwebsite at www.~lCRPonline,org The radiation from a nuclear power plant is included in the chart as part of the "Industrial and Occupational" fraction, <0.1 % The largest natural source of radiation is from radon, because radon gas travels in the air we breathe. Perhaps you know someone who had a CT scan at a hospital to check his or her bones, brain, or heart. CT scans are included in the chart as "Medical Procedures" which make up the next largest fraction.

Radiation Risk BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2022 UNIT 1, UNIT 2 and ISFSI (Docket Numbers 50-456, 50-457 and 72-73)

Current science suggests there is some risk from any exposure to radiation However, it is very hard to tell whether cancers or deaths can be attributed to very low doses of radiation or by something else. U.S radiation protection standards are based on the premise that any radiation exposure carries some risk.

The following graph is an example of one study that tries to relate risk from many different factors This graph represents risk as "Days of Lost Life Expectancy". All the categories are averaged over the entire population except Male Smokers, Female Smokers, and individuals that are overweight Those risks are only for people that fall into those categories. The category for Nuclear Power is a government estimate based on all radioactivity releases from nuclear power, including accidents and wastes.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2022 UNIT 1, UNIT 2 and ISFSI (Docket Numbers 50-456, 50-457 and 72-73)

Introduction This report quantifies the radioactive gaseous, liquid, solid radioactive waste (radwaste) releases, and summarizes the local meteorological data for the period from January 01, 2022 through December 31, 2022.

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 "ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT" as well as 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 inline sampling media and batch sample media from all ODCM specified effluent pathways. These pathways include continuous releases from the Unit 1 and Unit 2 Station Vent Stack, Condensate Polisher Sump, Waste Water Treatment, and Circulating Water Blowdown.

The ODCM specified effluent pathways also include batch releases from the Unit 1 and Unit 2 Primary Containments, Waste Gas Decay Tanks, and Liquid Radwaste Batch Release Tanks.

The volume and quantity of radioactive waste shipped offsite from Braidwood Nuclear Power Plant for processing and disposal was 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 A

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 purge flow rate, times the duration of the discharge The Auxiliary Building ventilation exhaust system is continually monitored for radioactive iodines (radioiodines) and particulates. These samples are obtained every seven days and analyzed via gamma spectroscopy.

Noble gas samples are obtained 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 Page 10of95

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2022 UNIT 1, UNIT 2 and ISFSI (Docket Numbers 50-456, 50-457 and 72-73) 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 lower limit of detection (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.

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

Particulate, 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 is 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, Ni-63, and gross alpha analysis by an offsite vendor. The vendor supplied data is utilized in conjunction with the volume of air released through the Auxiliary Building ventilation to quantify Sr-89/90, Fe-55, Ni-63, 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 calculated using volume of release, which is determined by purge flow rate multiplied by the duration of the discharge 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 sides of both units contain tritium. Minimal 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 large leaks (1000 gallons/day (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 (C-14) is assessed in continuous gaseous effluents using Electric Power Research lnstitute'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.

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, Fe-55 and Ni-63. 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 Procedure CY-AA-170-2100, Estimated Errors of Effluent Measurements provides the methodology to obtain an overall estimate of the error associated with radioactive effluents Estimated total error is calculated periodically and communicated as part of Appendix A Effluent and Waste Disposal Summary.

i.

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 The ODCM required lower limit of detection for airborne and liquid releases are as follows:

10. Radioactive Effluent Monitoring Instrumentation out of service for more than 30 Days

a.

Due to clearance order 00-CW-CWBDOOS-003 for CW Slowdown line inspections, 0PR01 J and 0PR90J were in RETS for greater than the required restoration time (14 days) as of 0800 on 06/18/2022. IR 04505297

b.

0RE-PR010 was inoperable for more than 30 days as of 1706 on 06/28/2022 due to clearance order 00-CW-CWBDOOS-003 for CW Slowdown line inspections. IR 04506772

c.

Loop CW032 was inoperable for more than 30 days as of 1800 on 07/01/2022 due to clearance order 00-CW-CWBDOOS-003 for CW Slowdown line inspections. IR 04508087

d.

0PR01J and 0PR90J were in RETS for greater than the required restoration time (14 days) as of 0900 on 10/03/2022. This was due to in-progress liquid release package (L-22-044) being written for the monitors being out of service and all required additional actions and samples being completed for the monitors being out of service. IR 04525724

11. Revisions to the ODCM No revisions to ODCM occurred in 2022.

12. Independent Spent Fuel Storage Installation (ISFSI)

An Independent Spent Fuel Storage Installation (ISFSI) was placed in service at Braidwood Station in 2011. The ISFSI is a closed system and the only exposure would be due to direct radiation, which is measured by Optically Stimulated Luminescent Dosimetry (OSLO). In 2022 the dose to the nearest resident from the ISFSI was estimated to be 2.S0E-01 mrem. This estimate was determined using environmental dosimeters from the Radiological Environmental Monitoring Program and extrapolating the dose from the ISFSI environmental dosimeters.

Sampling and Instrumentation Issues

a.

On 4/28/22 the CWBD compositor was checked per the weekly checklist for running status and it was found with the Program Complete in the status window. This is an indication that the compositor lost power at some point and was then restored but the program does not automatically resume sampling. The compositor was checked on 4/25/22 at 1155 when the weekly composite sample was obtained, and the program was Running. Sometime after 4/25/22 1155 when the compositor was last checked the compositor must have lost power. On 4/26/22 per operations log in eSOMs power was restored at the RSH. Chemistry personnel was unaware that power was lost at the RSH and no compensatory samples were obtained for the duration of 4/25/22 (after compositor check) to 4/28/22.

The liquid release L-22-23 of 0WX01T was secured on 4/25/22 at 13 00 IR 04496339

b.

The CWBD ODCM compositor was restarted on 7/11/22 following restoration of CWBD and the compositor was functioning as expected. On 7/15/22 chemistry technician identified that there was no power to the receptacle that the compositor was plugged into but there was power to the CWBD house still. An extension cord was utilized to plug the compositor into another receptacle to restore power and sampling capabilities to the ODCM compositor once again Approximately 2 liters of water was observed to be in the compositor jug It is unclear exactly when the power to the receptacle was lost. IR 04511153

c.

On 7/25/22 the CWBD compositor was collected for its weekly sample The technician noticed that there was a smaller volume of water in the compositor than expected The technician checked the program and noticed that the status read Program Complete. The technician reviewed the compositor log and it showed Program Complete on 7/20/22. Therefore, there were no samples being collected from 7/20/22 -7/25/22 according to the compositor log. The loss of power was originally thought to be the receptacle that it was plugged into and an extension cord was utilized to plug into a different outlet in the CWBD house. IR 04513016

d.

During the release (G-22-090) Unit 2 received an alarm on 2-5-C7 for "Cnmt Vent Isolation" SER pt#

0016. There was a containment release in progress and the containment vent isolation valves 2VQ005A & C auto closed as expected and 2VQ05C tripped. The alarm was due to a high alarm received on the 2AR 11 J radiation monitor. This was a spike that returned to normal status within seconds of the high alarm. The Containment Vent Isolation alarm was reset per the BwAR 2-5-C7 The alarm occurred about 2 minutes into the release and a flow rate on 2FI-VQ009 was not obtained prior to isolation. 2AR12J rad levels were normal at the time. IR 04488227

e.

While conducting a review on 2/16/22 it was identified that on February 5th, the H 0-28 air sampler that samples the intake of the Aux FW Diesel pumps went out of calibration 1 B & 28 DDAF pumps were both run on 2/10/22. Air sampler was swapped out with a calibrated one and the one in question was calibrated with all calibration checks passing successfully and no adjustments were needed Upon successful calibration checks of the HD-28 air sampler the time in question has been validated.

Radiological Impact on Man

1.

Dose to Members of the Public at or Beyond Site Boundary Per ODCM Chapter 6.1 the Annual Radioactive Effluent Release Report shall include an assessment of radiation doses to the hypothetically highest exposed MEMBER OF THE PUBLIC from reactor releases, ISFSI and other nearby uranium fuel cycle sources. This includes doses from primary effluent pathways and direct radiation for the previous calendar year. The ODCM does not require population doses to be calculated. For purposes of calculation, the following assumptions were made per the ODCM Long term annual average meteorology X/Q and D/O and actual gaseous effluent releases were used.

Gamma air dose, Beta air dose, Total Body and Skin doses were attributed to noble gas releases.

Critical organ and age group dose attributed to iodine, particulate, carbon-14 and tritium releases.

A 0.7 shielding factor was assumed to account for shielding due to occupancy of structures Doses, Design Objective Limit, and Dose Limit comparisons reported combined for the site for both Unit 1 and Unit 2 together.

Dosimetry measurements obtained from the highest station values in the Radiological Environmental Monitoring Program were used to calculate dose to the nearest residence from the Independent Spent Fuel Storage Installation (ISFSI). The dose measured at the station was extrapolated to the residence location.

The highest doses from the critical organ and critical age group for each release pathway was summed and added to the net dosimetry measurement from nearest residence to the ISFSI for 40CFR190 and 10CFR72.104 dose compliance.

Evaluation of 40CFR 190 and 10CFR72.104 dose is used to demonstrate compliance to 10CFR 20 and satisfy station RETS and Technical Specifications.

a.

Gaseous Releases Calculated total body dose was 2.28E-01 mrem. The critical age-organ was the child-bone and the organ dose was 1 08E+00 mrem.

b.

Liquid Releases Calculated total body dose was 2.59E-01 mrem. The critical age-organ was the child-GI-LU and the organ dose was 2.60E-01 mrem.

c.

40CFR 190 and 10CFR72.104 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 (ODCM A.4.2 Total Dose. Equation A-24). The total dose.
