CY-BR-170-301 Revision 10 Page 7 of 353 CHAPTER 1 -INTRODUCTION The Offsite Dose Calculation Manual (ODCM) presents a discussion of the following:

• The basic concepts applied in calculating offsite doses from nuclear plant effluents.

• The regulations and requirements for the ODCM and related programs.

• The methodology and parameters for the offsite dose calculations used by the nuclear power stations to assess impact on the environment and compliance with regulations.

The methodology detailed in this manual is intended for the calculation of radiation doses during routine (i.e., non-accident) conditions. The calculations are normally performed using a computer program. Manual calculations may be performed in lieu of the computer program.

The dose effects of airborne radioactivity releases predominately depend on meteorological conditions (wind speed, wind direction, and atmospheric stability). For airborne effluents, the dose calculations prescribed in this manual are based on historical average atmospheric conditions. This methodology is appropriate for estimating annual average dose effects and is stipulated in the Bases Section of the Radiological Effluent Technical Standards (RETS) of all Exelon Nuclear nuclear power stations.

1.1 STRUCTURE OF THIS MANUAL This manual is the ODCM for the following Exelon Nuclear power stations: Braidwood, Byron, Dresden, LaSalle, and Quad Cities. It is divided into two parts. The material in the first part is generic (applicable to more than one station) and consists of Chapters 1 through 7 and Appendices A through C. The material in the second part is station (or site) specific. Therefore, there are six separate sets of station-specific sections each containing three chapters (chapters 10, 11, 12) and an appendix (App. F).

The chapters of the generic section provide a brief introduction to and overview of Exelon Nuclear's offsite dose calculation methodology and parameters. Appendices A and B provide detailed information on specific aspects of the methodology. Appendix C contains tables of values of the generic parameters used in offsite dose equations.

The station-specific section provides specific requirements for the treatment and monitoring of radioactive effluents, for the contents of the Radiological Environmental Monitoring Program (REMP) and the Radiological Effluent Technical Standards (RETS). These three programs are detailed in ODCM Chapters 10, 11 and 12, respectively. Appendix F contains tables of values for the station-specific parameters used in the offsite dose equations. References are provided as required in each station-specific chapter and appendix.

An ODCM Bases and Reference Document (see Reference 101) provides description of the bases for the methodology and parameters discussed in the generic section of the ODCM. This is a stand-alone document and is not considered to be a part of the ODCM.

CY-BR-170-301 Revision 10 Page 8 of 353 CHAPTER 2 - REGULATIONS AND GUIDELINES

2.0 INTRODUCTION

This chapter of the ODCM seNes to illustrate the regulations and requirements that define and are applicable to the ODCM. Any information provided in the ODCM concerning specific regulations are not a substitute for the regulations as found in the Code of Federal Regulations (CFR) or Technical Specifications.

2.1 CODE OF FEDERAL REGULATIONS Various sections of the Code of Federal Regulations (CFR) require nuclear power stations to be designed and operated in a manner that limits the radiation exposure to members of the public. These sections specify limits on offsite radiation doses and on effluent radioactivity concentrations and they also require releases of radioactivity to be "As Low As Reasonably Achievable". These requirements are contained in 10CFR20, 10CFR50 and 40CFR190. In addition, 40CFR141 imposes limits on the concentration of radioactivity in drinking water provided by the operators of public water systems.

2.1.1 10CFR20, Standards for Protection Against Radiation This revision of the ODCM addresses the requirements of 10CFR20. The 10CFR20 dose limits are summarized in Table 2-1.

2.1.2 Design Criteria (Appendix A of 10CFR50)

Section 50.36 of 10CFR50 requires that an application for an operating license include proposed Technical Specifications. Final Technical Specifications for each station are developed through negotiation between the applicant and the NRC. The Technical Specifications are then issued as a part of the operating license, and the licensee is required to operate the facility in accordance with them.

Section 50.34 of 10CFR50 states that an application for a license must state the principal design criteria of the facility. Minimum requirements are contained in Appendix A of 10CFR50.

2.1.3 ALARA Provisions (Appendix I of 10CFR50)

Sections 50.34a and 50.36a of 10CFR50 require that the nuclear plant design and the station RETS have provisions to keep levels of radioactive materials in effluents to unrestricted areas "As Low As Reasonably Achievable" (ALA RA). Although 10CFR50 does not impose specific limits on releases, Appendix I of 10CFR50 does provide numerical design objectives and suggested limiting conditions for operation. According to Section I of Appendix I of 10CFR50, design objectives and limiting conditions for operation, conforming to the guidelines of Appendix I "shall be deemed a conclusive showing of compliance with the "As Low As Reasonably Achievable" requirements of 10CFR50.34a and 50.36a."

An applicant must use calculations to demonstrate conformance with the design objective dose limits of Appendix I.

The calculations are to be based on models and data such that the actual radiation exposure of an individual is "unlikely to be substantially underestimated" (see 10CFR50 Appendix I, Section 111.A.1 ).

The guidelines in Appendix I call for an investigation, corrective action and a report to the NRC whenever the calculated dose due to the radioactivity released in a calendar quarter exceeds one-half of an annual design objective. The guidelines also require a suNeillance program to monitor releases, monitor the environment and identify changes in land use.

2.1.4 40CFR190, Environmental Radiation Protection Standards for Nuclear Power Operations Under an agreement between the NRC and the EPA, the NRC stipulated to its licensees in Generic Letter 79-041 that "Compliance with Radiological Effluent Technical Specifications (RETS), NUREG-0472 (Rev.2) for PWR's or NUREG-0473 (Rev.2) for BWR's, implements the LWR provisions to meet 40CFR190". (See Reference 103 and 49.)

July 2018

CY-BR-170-301 Revision 10 Page 9 of 353 The regulations of 40CFR 190 limit radiation doses received by members of the public as a result of operations that are part of the uranium fuel cycle. Operations must be conducted in such a manner as to provide reasonable assurance that the annual dose equivalent to any member of the public due to radiation and to planned discharges of radioactive materials does not exceed the following limits:

• 25 mrem to the total body

• 75 mrem to the thyroid

• 25 mrem to any other organ An important difference between the design objectives of 10CFR50 and the limits of 40CFR 190 is that 10CFR50 addresses only doses due to radioactive effluents. 40CFR190 limits doses due to effluents and also to radiation sources maintained on site. See Section 2.4 for further discussion of the differences between the requirements of 10CFR50 Appendix I, 40CFR190 and 10CFR72.104.

2.1.5 40CFR141, National Primary Drinking Water Regulations The following radioactivity limits for community water systems were established in the July, 1976 Edition of 40CFR141:

• Combined Ra-226 and Ra-228: ::5. 5 pCi/L.

• Gross alpha (particle activity including Ra-226 but excluding radon and uranium): ::5. 15 pCi/L.

• The average annual concentration of beta particle and photon radioactivity from man-made radionuclides in drinking water shall not produce an annual dose equivalent to the total body or any internal organ greater than 4 mrem/yr.

The regulations specify procedures for determining the values of annual average radionuclide concentration which produce an annual dose equivalent of 4 mrem. Radiochemical analysis methods are also specified. The responsibility for monitoring radioactivity in a community water system falls on the supplier of the water. However, some of the Exelon Nuclear stations have requirements related to 40CFR 141 in their specific RETS. For calculation methodology, see Section A.6 of Appendix A.

2.2 RADIOLOGICAL EFFLUENT TECHNICAL STANDARDS The Radiological Effluent Technical Standards (RETS) were formerly a subset of the Technical Specifications.

They implement provisions of the Code of Federal Regulations aimed at limiting offsite radiation dose. The NRC published Standard Radiological Effluent Technical Specifications for PWRs (Reference 2) and for BWRs (Reference 3) as guidance to assist in the development of technical specifications. These documents have undergone frequent minor revisions to reflect changes !n plant design and evolving regulatory concerns. The Radiological Effluent Technical Specifications have been removed from the Technical Specifications and placed in the ODCM as the Radiological Effluent Technical Standards (RETS) (see Reference 90). The RETS of each station are similar but not identical to the guidance of the Standard Radiological Effluent Technical Specifications.

2.2.1 Categories The major categories found in the RETS are the following:

• Definitions A glossary of terms (not limited to the ODCM).

July 2018

CY-BR-170-301 Revision 10 Page 10 of 353

• Instrumentation This section states the Operability Requirements (OR) for instrumentation performance as well as the associated Surveillance Requirements. The conservative alarm/trip setpoints ensure regulatory compliance for both liquid and gaseous effluents. Surveillance requirements are listed to ensure ORs are met through testing, calibration, inspection and calculation. Also included are the bases for interpreting the requirements. The Operability Requirement (OR) is the ODCM equivalent of a Limiting Condition for Operation (LCO) as defined in both the NRC published Standard Radiological Effluent Technical Specifications and the stations' Technical Specifications.

• Liquid Effluents This section addresses the limits, special reports and liquid waste treatment systems required to substantiate the dose due to liquid radioactivity concentrations to unrestricted areas. Surveillance Requirements and Bases are included for liquid effluents.

• Gaseous Effluents This section addresses the limits, special reports and gaseous radwaste and ventilation exhaust treatment systems necessary for adequate documentation of the instantaneous offsite radiation dose rates and doses to a member of the public. Surveillance Requirements and Bases are included for gaseous effluents.

• Radiological Environmental Monitoring Program This section details the Radiological Environmental Monitoring Program (REMP) involving sample collection and measurements to verify that the radiation levels released are minimal. This section describes the annual land use census and participation in an interlaboratory comparison program.

Surveillance Requirements and Bases are included for environmental monitoring.

• Reports and Records This section serves as an administrative guide to maintain an appropriate record tracking system. The management.of procedures, record retention, review/audit and reporting are discussed.

2.3 OFFSITE DOSE CALCULATION MANUAL The NRC in Generic Letter 89-01 defines the ODCM as follows (not verbatim) (see Reference 90):

The Offsite Dose Calculation Manual (ODCM) shall contain the methodology and parameters used in the calculation of offsite doses resulting from radioactive gaseous and liquid effluents, in the calculation of gaseous and liquid effluent monitoring* Alarm/Trip Setp_oints, and in the conduct of the Radiological Environmental Monitoring Program. The ODCM shall also contain (1) the Radioactive Effluent Controls and Radiological Environmental Monitoring Programs and (2) descriptions of the Information that should be included in the Annual Radiological Environmental Operating and Annual Radioactive Effluent Release Reports.

Additional requirements for the content of the ODCM are contained throughout the text of the RETS.

2.4 OVERLAPPING REQUIREMENTS In 10CFR20, 10CFR50, 40CFR190 and 10CFR72.104, there are overlapping requirements regarding offsite radiation dose and dose commitment to the total body. In 10CFR20.1301 the total effective dose equivalent (or TEDE) to a member of the public is limited to 100 mrem per calendar year. In addition, Appendix I to 10CFR50 establishes design objectives on annual total body dose or dose commitment of 3 mrem per reactor for liquid effluents and 5 mrem per reactor for gaseous effluents (see 10CFR50 Appendix I, Sections II.A and ll.B.2(a)).

Finally, 40CFR190 and 10CFR72.104 limits annual total body dose or dose commitment to a member of the public to 25 mrem due to all uranium fuel cycle operations.

July 2018

CY-BR-170-301 Revision 10 Page 11 of 353 While these dose limits/design objectives appear to overlap, they are different and each is addressed separately by the RETS. Calculations are made and reports are generated to demonstrate compliance to all regulations.

Refer to Tables 2-1, 2-2 and 2-3 for additional information regarding instantaneous effluent limits, design objectives and regulatory compliance.

2.5 DOSE RECEIVER METHODOLOGY Table 2-2 lists the location of the dose recipient and occupancy factors, if applicable. Dose is assessed at the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates the maximum potential exposures. The dose calculation methodology is consistent with the methodology of NUREG 0133 (Reference 14) with dose factors from Regulatory Guide 1.109 (Reference 6). Dose is therefore calculated to a maximum individual. The maximum individual is characterized as "maximum" with regard to food consumption, occupancy and other usage of the area in the vicinity of the plant site. Such a "maximum individual" represents reasonable deviation from the average for the population in general. In all physiological and metabolic respects the maximum individual is assumed to have those characteristics that represent averages for their corresponding age group. Thus, the dose calculated is very conservative compared to the "average" (or typical) dose recipient who does not go out of the way to maximize radioactivity uptakes and exposure.

Finally Table 2-3 relates the dose component (or pathway) to specific ODCM equations and the appropriate regulation.

2 These limits are not directly applicable to nuclear power stations. They are applicable to the owners or operators of public water systems. However, the RETS of some of the Exelon Nuclear nuclear power stations require assessment of compliance with these limits. For additional information, see Section A.6 of Appendix A.

CY-BR-170-301 Revision 10 Page 18 of 353 CHAPTER3 EXPOSURE PATHWAYS

3.0 INTRODUCTION

Figure 3-1 illustrates some of the potential radiation exposure pathways to humans due to routine operation of a nuclear power station. These exposure pathways may be grouped into three categories:

• Airborne Releases Exposures resulting from radioactive materials released with gaseous effluents to the atmosphere.

• Liquid Releases Exposures resulting from radioactive materials released with liquid discharges to bodies of water.

• Radiation from Contained Sources Exposures to radiation from contained radioactive sources.

When performing radiation dose calculations, only exposure pathways that significantly contribute(;:::: 10%) to the total dose of interest need to be evaluated. The radiation dose from air and water exposure pathways are routinely evaluated. (see Regulatory Guide 1.109, Reference 6.)

3.1 AIRBORNE RELEASES For airborne releases of radioactivity, the NRG considers the following pathways of radiation exposure of persons:

• External radiation from radioactivity airborne in the effluent plume.

• External radiation from radioactivity deposited by the plume on the ground.

• Ingestion of radioactivity on, or in, edible vegetation (from direct plume deposition).

• Ingestion of radioactivity that entered an animal food product (milk or meat) because the animal ingested contaminated feed, with the contamination due to direct deposition on foliage.

• Inhalation of radioactivity in the plume.

Dose for airborne releases is assessed at the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates the maximum potential exposures.

3.2 LIQUID RELEASES For liquid releases of radioactivity (Figure 3-1), the NRG considers the following pathways of radiation exposure of persons:

• Ingestion of aquatic food (e.g., fish or invertebrate) obtained from the body of water to which radioactive station effluents are discharged.

• Ingestion (drinking) of potable water contaminated by radioactive liquid effluents discharged from the station.

For the aquatic food pathway, only fish is considered since it is the only significant locally produced aquatic food consumed by humans.

The stations omit the pathways involving irrigation and animal consumption of contaminated water because these pathways were determined to be insignificant. The stations also omit the pathway of radiation exposure from shoreline sediment because this pathway was also found to be insignificant (see ODGM Bases and Reference Document, Section 0.3.2).

July 2018

CY-BR-170-301 Revision 10 Page 19 of 353 The stations have also verified that the dose contribution to people participating in water recreational activities (swimming and boating) is negligible. (See ODCM Bases and Reference Document, Reference 101, Tables 0-3 and 0-4) This pathway was not addressed explicitly in Regulatory Guide 1.109. Thus, the stations also omit dose assessments for the water recreational activities pathway.

Periodically, the Illinois Army Corps of Engineers dredges silt and debris from the river beds near Exelon Nuclear nuclear stations. As a part of the land use census, Exelon Nuclear will determine if the Corps performed dredging within one mile of the discharge point. If so, Exelon Nuclear will obtain spoils samples, through its REMP vendor, for analysis. The impact to the offsite dose will be evaluated on a case by case basis and added to the station annex of the ODCM when applicable.

In addition, to assure that doses due to radioactivity in liquid effluents will be ALARA, concentrations will be limited to ten times (1 Ox) the values given in 10CFR20 Appendix B, Table 2; Column 2. Specific limitations for concentrations of entrained noble gases are contained in the stations' Radiological Effluent Technical Standards (RETS).

3.3 RADIATION FROM CONTAINED SOURCES Radioactivity contained within tanks, pipes or other systems and contained radioactive material or waste stored on site can produce radiation at offsite locations. Annual offsite radiation doses near the stations due to such sources were judged to be negligible in comparison with applicable limits except for doses due to BWR turbine skyshine and potential doses due to radioactive waste storage facilities (excludes radioactive material storage).

See ODCM Bases and Reference Document, Reference 101. Changes or modifications to the power station that may impact the offsite dose through increases to the direct radiation levels need to be evaluated on a case by case basis and added to Chapter 12 of the station annex to the ODCM when applicable (e.g.; the Old Steam Generator Storage Facilities).

CY-BR-170-301 Revision 10 Page 21 of 353 CHAPTER4 METHODOLOGY

4.0 INTRODUCTION

This chapter provides an introduction to the methodology used by Exelon Nuclear to calculate offsite radiation doses resulting from the operation of nuclear power stations. Additional explanation and details of the methodology are provided in Appendices A and B. Appendix A discusses each dose limit in the RETS and provides the associated assessment equations. Appendix B describes methods used to determine values of parameters included in the equations.

4.1 IMPORTANT CONCEPTS AND PARAMETERS 4.1.1 Dose The dose calculation equations contained in the ODCM are based on two types of exposure to radiation; external and internal exposure. The first type of exposure is that resulting from radioactive sources external to the body (including radiation emanating from an effluent plume, radiation emanating from radioactivity deposited on the ground and radiation emanating from contained sources (also referred to as direct radiation)). Exposure to radiation external to the body only occurs while the source of the radioactivity is present.

Internal exposure occurs when the source of radioactivity is inside the body. Radiation can enter the body by breathing air containing the radioactivity, or by consumption of food or drinking water containing radioactivity.

Once radioactivity enters the body and becomes internal radiation, a person will continue to receive radiation dose until the radioactivity has decayed or is eliminated by biological processes. The dose from this type of exposure is also termed dose commitment, meaning that the person will continue to receive dose even-though the plume containing the radioactivity has passed by the individual, or even-though the individual is no longer drinking water containing radioactivity.

The regulations addressed by the ODCM may require assessment of either type of exposure to radiation or of both types in summation.

The term dose is used instead of the term "dose equivalent," as defined by the International Commission on Radiological Units and Measurements (ICRU). When applied to the evaluation of internal deposition of radioactivity, the term "dose," as used in the ODCM, includes the prospective dose component arising from retention in the body beyond the period of environmental exposure, i.e., the dose commitment. The dose commitment is evaluated over a period of 50 years.

4.1.2 Exposure Pathways All of the exposure pathways are discussed in Chapter 3. This section presents the exposure pathways addressed by Exelon Nuclear nuclear stations in the ODCM and associated software.

For exposure to radiation from contained sources, the station will consider exposure from radiation emanating from onsite radwaste storage facilities when they are put into operation.

For releases of radioactivity in airborne effluents the primary pathways are the following:

• Direct radiation from contained sources.

• Direct radiation from an effluent plume.

• Direct radiation from radioactivity deposited on the ground by a plume.

• Inhalation of radioactivity in a plume.

• Ingestion of radioactivity that entered the food chain from a plume that deposited radioactivity on vegetation.

July 2018

CY-BR-170-301 Revision 10 Page 22 of 353 For releases of radioactivity in liquid effluents, the exposure pathways considered are human consumption of water and fish.

4.1.3 Categories of Radioactivity Radionuclide content of effluent releases from nuclear power stations can be categorized according to the characteristics of the radionuclides. In evaluating doses associated with a particular pathway, only those categories of radionuclides that significantly contribute to the dose need to be included in the dose calculations (See Section 3.0). The categories of radionuclides considered by the Exelon Nuclear nuclear power stations for each of the airborne pathways are summarized in Table 4-1. Selection of the significant airborne pathways was based on the following:

• The requirements in the RETS (see discussion in Appendix A)

• Applicable regulatory guidance (References 6 and 14), and

• A study of the potential radiological implications of nuclear facilities in the upper Mississippi River basin (Reference 20).

Calculations were used to determine which radionuclides were significant for a particular pathway. For example, in the case of direct radiation from a plume of airborne radioactivity, it was found that radiation from noble gases is significant and radiation from radioactive iodine was not. The dose rate per unit of airborne radioactivity concentration is about the same for noble gases and radioactive iodine since they emit comparable types and energies of radiation. However, the quantity of noble gas radioactivity released in routine nuclear plant operation typically exceeds the quantity of radioactive iodine by a factor of about 10,000.

As another example, consider the inhalation pathway. Here, the calculations showed that the dose commitment due to radioactive iodine was significant but the dose commitment due to radioactive noble gases was not significant and can be excluded from the compliance calculations for the inhalation pathway. This is true despite the fact that a much larger quantity of noble gas radioactivity is released. The reason for this is that the solubility of noble gas in body tissue is very low, whereas the inhaled radioactive iodine does concentrate in specific body organs such as the thyroid (see the discussion on Pages 228 and 231 to 234 of Reference 38).

4.1.4 Atmospheric Release Point Classifications The dose impact from airborne release of radioactivity is determined by the height of the release of the effluent plume relative to the ground and by the location of the dose recipient.

The height an effluent plume maintains as it travels above the ground is related to the elevation of the release point and to the height of structures immediately adjacent as follows:

• If the elevation of the release point is sufficiently above the height of any adjacent structures, the plume will remain elevated for considerable distances.

• If the elevation of the release point is at or below the heights of adjacent structures, the plume is likely to be caught in the turbulence of the wakes created by wind passing over the buildings. The plume elevation would then drop to ground level.

• If the elevation of the release point is not significantly above the heights of adjacent structures, then the plume may be elevated or at ground level.

July 2018

CY-BR-170-301 Revision 10 Page 23 of 353 For the calculations of this manual, each established release point has been designated as belonging to one of three release point classifications:

• Stack (or Elevated) Release Points (denoted by the letter Sor subscripts)

These are release points approximately twice the height of adjacent solid structures. Releases are treated as elevated releases unaffected by the presence of the adjacent structures.

• Ground Level Release Points (denoted by the letter G or subscript g)

These are release points at ground level or lower than adjacent solid structures. Releases are considered drawn into the downwind wake of these structures and are treated as ground level releases.

• Vent (or Mixed Mode) Release Points (denoted by the letter V or subscript v)

These are release points as high or higher than adjacent solid structures but lower than twice the structure's heights. These releases are treated as a mixture of elevated and ground level releases. The proportion of the release attributed to either elevated or ground level in a vent release is determined by the ratio of stack exit velocity to the wind speed (see Section 8.1.2.4 of Appendix 8).

The definitions of these classifications are based on Regulatory Guide 1.111 (Reference 7). A list of the classifications of specific airborne release points for each of the Exelon Nuclear nuclear power stations is contained in Table A-2 in Appendix A.

4.1.5 Historical Average Atmospheric Conditions The dispersion characteristics of airborne effluents from a nuclear power station are dependent on weather conditions. Meteorological factors that directly affect the concentration of airborne radioactivity in a plume include the following:

• Wind Direction The concentration of radioactivity is highest in the direction toward which the wind is blowing.

• Wind Speed Greater wind speeds produce more dispersion and consequently lower concentrations of radioactivity.

• Atmospheric Turbulence The greater the atmospheric turbulence, the more a plume spreads both vertically and horizontally. For calculations in this manual, the degree of turbulence is classified by use of seven atmospheric stability classes, designated A (extremely unstable) through G (extremely stable). The seven classes and some of their characteristics are listed in Table C-4 of Appendix C.

July 2018

CY-BR-170-301 Revision 10 Page 24 of 353 Meteorological conditions strongly impact the values of various parameters applied in the dose calculations of this manual. These include:

• The Relative Concentration Factors x!Q and gamma-x/Q (Section 4.1.6)

• The Relative Deposition Factor D/Q (Section 4.1. 7)

The bases sections of the Standard Radiological Effluent Technical Specifications (guidance documents NUREGs 0472, 0473, 1301 and 1302) and the RETS specify that dose calculations be based on "historical average atmospheric conditions". Therefore, this manual provides values for the above parameters that are based on station-specific historical average meteorological conditions. These values were obtained by averaging hourly values of the parameters over a long-term, several-year period of record. The averaging period was based on calendar years in order to avoid any bias from weather conditions associated with any one season. The period of record is identified in each of the tables providing the values (see Appendix F).

4.1.6 Relative Concentration Factors x/c;land Gamma-x/Q '

A person immersed in a plume of airborne radioactivity is exposed to radiation from the plume and may also inhale some of the radioactivity from the plume. The concentration of radioactivity in air near the exposed person must be calculated to adequately evaluate doses resulting from any inhalation. The relative concentration factor x!Q (referred to as "chi over Q") is used to simplify these calculations. x/Qis the concentration of radioactivity in air, at a specified location, divided by the radioactivity release rate. x/Qhas the following units:

3 Units of xlc;l= (xCi/m ) I (µCi/sec) = sec/m 3 Station-specific values of xtQ are provided for each nuclear power station in Table F-5 of Appendix F. These values are based on historical average atmospheric conditions (see Section 4.1.5).

For each of the release point classifications (eg. stack, vent and ground level) and for the 16 compass-direction sectors (N, NNE, etc.), Table F-5 provides the maximum value of xtQ for locations at or beyond the unrestricted area boundary.

The value of x!Qfor each sector reflects the fraction of time that the wind blew into that sector and the distribution of wind speeds and atmospheric stability classes during that time. Note that the value would be zero if the wind never blew into the sector.

The gamma-x/Q provides a simplified method of calculating gamma air dose and dose rates for a finite and/or elevated plume. It is used in place of the semi-infinite plume model that tends to underestimate gamma air dose for elevated plumes. Use of the gamma-x/Q also corrects for the tendency of the semi-infinite plume model to overestimate gamma air dose for mixed mode and ground level releases.

The methodologies for determining x!Q and gamma-x/Q are discussed in detail in Section B.3 of Appendix B.

July 2018

CY-BR-170-301 Revision 10 Page 25 of 353 4.1.7 Relative Deposition Factor D/Q As a plume travels away from its release point, portions of the plume may touch the ground and deposit radioactivity on the ground and/or on vegetation. Occurrences of such deposition are important to model since any radioactivity deposited on the ground or on vegetation may directly expose people and/or may be absorbed into food products which can ultimately be ingested by people. The relative deposition factor is used to simplify the dose calculations for these pathways.

The relative deposition factor D/Q is the rate of deposition of radioactivity on the ground divided by the radioactivity release rate. Its value was determined for specific conditions. In this manual it has the following units:

2 Units of D/Q = [(pCi/sec)/m ]/(pCi/sec) = 1/m2 The values of D/Q are affected by the same parameters that affect the values of x/Q: release characteristics, meteorological conditions and location (see Section 4.1.6). Station-specific values of D/Q are provided for each Exelon Nuclear nuclear power station in Appendix F Tables F-5 and F-6. These values are based on historical average atmospheric conditions (see Section 4.1.5).

For each release point classification and for each of the 16 compass-direction sectors (N, NNE, etc.), Table F-5 provides the maximum value of D/Q for locations at or beyond the unrestricted area boundary. In Table F-6, values of D/Q are given for the locations of the nearest milk and meat producers within 5 miles of the nuclear power station. The methodology for determining D/Q is discussed in Section 8.4 of Appendix B.

4.1.8 Dose Factors Various dose factors are used in this manual to simplify the calculation of radiation doses. These factors are listed in Table 4-2. Definitions of these factors are given in the remainder of this chapter. Methods of determining their values are addressed in Appendix B.

4.2 AIRBORNE RELEASES 4.2.1 Gamma Air Dose The term 'gamma air dose' refers to the component of dose absorbed by air resulting from the absorption of energy from photons emitted during nuclear and atomic transformations, including gamma rays, x-rays, annihilation radiation, and Bremsstrahlung radiation (see footnote on page 1.109-19 of Regulatory Guide 1.109).

The noble gas dose factors of Reg. Guide 1.109, Table B-1 are based upon assumption of immersion in a semi-infinite cloud. For ground level and mixed mode releases this tends to over estimate the gamma air dose arising from a plume that is actually finite in nature.

For elevated releases, the Reg. Guide 1.109 noble gas dose factors will underestimate exposure as they consider only immersion and not that portion of exposure arising from sky shine. At distances close in to the point of elevated release, the ground level concentration as predicted by xtQ will be essentially zero. In such a case, the sky shine component of the exposure becomes significant and must be considered.

The gamma-x/Q provides a simplified method of calculating gamma air dose and dose rates for a finite and/or elevated plume. The methodology of Reg. Guide 1.109, Section C.2 and Appendix B provide the methodology for calculating finite cloud gamma air dose factors from which the gamma-x/Q values can be derived. Section B.5 addresses the calculation of these dose factors.

Three gamma-x/Q values are defined: (x/Q) 51 , (x/Q)l and (x/Q) 91 for stack, vent and ground level releases, respectively. Section B.3.5 addresses the calculation of the gamma-x/Q values.

July 2018

CY-BR-170-301 Revision 10 Page 26 of 353 4.2.1.1 Finite Cloud Gamma Air Dose Factor The finite cloud gamma air dose factor is determined by calculating the gamma dose rate to air (at a specific location and corresponding to a given release rate) and dividing that dose rate by the corresponding release rate:

Finite Cloud Gamma Air Dose Factor= [(mrad/yr)/(µCi/sec)]

The methodology for this calculation is discussed in Section B.5 of Appendix 8. The calculation is complex because the dose rate at any given point is affected by the radioactivity concentration and distance. Calculation of the finite cloud gamma air dose factor takes into consideration release characteristics, meteorological conditions and location (see Section 4.1.6). Additionally, the value is affected by radiological parameters: the distribution of energies and intensities for gamma emissions from each specific radionuclide and the photon attenuation characteristics of air.

In the ODCM, station-specific values of gamma dose factors are provided for each station in Appendix F, Table F-7. These values are based on historical average atmospheric conditions (see Section 4.1.5). For the release point classification and for each of the 16 compass-direction sectors, Table F-7 provides the maximum value of the gamma air dose factor for noble gas radionuclides at the unrestricted area boundary. The value includes a correction for radioactive decay during transport of the radionuclide from the release point to the dose calculation location.

4.2.1.2 Semi-Infinite Cloud Gamma Air Dose Factor The semi-infinite cloud gamma dose factor is the gamma air dose rate divided by the concentration of radioactivity in air at the dose calculation location. Values of these gamma dose factors are radionuclide specific and are provided in Appendix C, Table C-9.

The semi-infinite cloud gamma dose factor is used in conjunction with gamma-x/Q to calculate noble gas gamma air dose and dose rate for elevated and finite noble gas plumes. The gamma-x/Q is defined such that for a given finite cloud the semi-infinite cloud methodology will yield the same gamma air dose as the finite cloud methodology.

4.2.2 Beta Air Dose The term 'beta air dose' refers to the component of dose absorbed by air resulting from the absorption of energy from emissions of beta particles, mono-energetic electrons and positrons during nuclear and atomic transformations (see the footnote on Page 1.109-20 of Regulatory Guide 1.109).

The Beta Air Dose Factor The beta air dose factor is the beta air dose rate divided by the concentration of radioactivity in air at the dose calculation location. Values of the beta air dose factor are radionuclide specific and are provided in Appendix C Table C-9.

4.2.3 Total Body Dose and Dose Rate Total Body Dose Equation A-3 of Appendix A is used to calculate dose to the total body from noble gas radionuclides released in gaseous effluents. The total body dose equation is similar to that used to calculate gamma air dose (Equation A-1 of Appendix A).

July 2018

CY-BR-170-301 Revision 10 Page 27 of 353 Total Body Dose Rate Equation A-5 of Appendix A is used to calculate dose rate to the total body. The assumptions used for this equation are the same as those used in the calculation of total body dose (Equation A-3 of Appendix A).

The Total Body Dose Factor The total body dose factor is the total body dose rate divided by the radioactive release rate. Values for the total body dose factor are site specific and are provided in Table C-9 of Appendix C.

4.2.4 Skin Dose and Dose Rate Skin Dose Equation A-4 of Appendix A is used to calculate dose to skin from noble gas radionuclides released in gaseous effluents. The skin dose is the summation of dose to the skin from beta and gamma radiation.

The equation for beta dose to skin is similar to that used to calculate beta dose to air (Equation A-2 of Appendix A) except that beta skin dose factors are used instead of beta air dose factors. The beta skin dose factor differs from the beta air dose factor by accounting for the attenuation of beta radiation by the dead layer of skin. The dead layer of skin is not susceptible to radiation damage and therefore is not of concern. The beta dose to the skin from non-noble gases is insignificant and is not calculated for the reason described in Section 4.1.3. When calculating the beta contribution to skin dose, no reduction is included in the calculations due to shielding provided by occupancy of residential structures.

The equation for gamma dose to skin is similar to that used to calculate gamma dose to air except for the following:

• Equation A-4 of Appendix A includes a units conversion factor 1.11 rem/rad to convert from units of gamma air dose (rad) to units of tissue dose equivalent (rem).

Equation A-4 of Appendix A uses gamma air dose factors not gamma total body dose factors.

Skin Dose Rate Equation A-6 of Appendix A is used to calculate dose rate to skin. The assumptions are the same as those used in the calculation of skin dose (Equation A-4 of Appendix A).

The Skin Dose Factor Values of the beta air dose factors and skin dose factors are nuclide specific and are provided in Table C-9 of Appendix C for 15 noble gas radionuclides.

4.2.5 Ground Radiation Equations A-7 and A-8 of Appendix A are used to calculate the total body dose due to non-noble gas radionuclides released in gaseous effluents and deposited on the ground.

July 2018

CY-BR-170-301 Revision 10 Page 28 of 353 Comment Note that if there is no release of radionuclide i during a given time period, then the deposition rate is zero, the ground plane concentration is zero and the resulting dose due to ground deposition is zero. If there is a release of radionuclide i, the ground concentration is computed as if that release had been occurring at a constant rate for the ground deposition time period.

The Ground Plane Dose Conversion Factor The ground plane dose conversion factor is the dose rate to the total body per unit of radioactivity concentration on the ground. Values of the ground plane dose conversion factor that are calculated by assuming constant concentration over an infinite plane are provided for various radionuclides in Table C-10 of Appendix C.

4.2.6 Inhalation Dose Radioactivity from airborne releases of radioactive iodine, particulate and tritium can enter the body through inhalation. Equations A-7 and A-9 of Appendix A are used to calculate dose commitment to the total body or organs due to inhalation of non-noble gas radionuclides released in gaseous effluents.

The Inhalation Dose Factor Values for the inhalation dose commitment factor are nuclide specific and are taken from Reg. Guide 1.109 (Reference 6) Tables E-7, 8, 9 and 10. These tables include data for four age groups (adult, teenager, child and infant) and seven body organs.

Dose Rate The inhalation dose rate is the rate at which dose is accrued by an individual breathing contaminated air.

Equation A-16 of Appendix A is used to calculate dose commitment rate to an organ due to inhalation of non-noble gas radionuclides. The assumptions are the same as used in the calculation of inhalation dose. The dose rate is determined for the child age group in accordance with the guidance found in NUREGs 0472, 0473, 1301 and 1302 (References 2, 3, 105 and 106).

4.2.7 Ingestion Airborne releases of radioactive iodine, particulate and tritium can enter the food chain through deposition on vegetation. The radioactivity can be ingested by humans who consume the vegetation or who consume products (e.g., milk or meat) of animals who have fed on the contaminated vegetation. Each Exelon Nuclear nuclear power station considers the following ingestion pathways:

• Vegetables

• Milk

• Meat.

Equations A-7 and A-10 through A-15 of Appendix A are used to calculate the dose due to ingestion of food containing non-noble gas radionuclides released in gaseous effluents. Dose is assessed at the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates the maximum potential exposures.

Values of the ingestion dose commitment factor are the same for each Exelon Nuclear nuclear power station. The components of this factor are not impacted by station-specific parameters. The station-specific aspects of the calculation of ingestion dose only concern the quantity of radioactivity ingested. Values of the ingestion dose commitment factors are taken from Reg. Guide 1.109 Tables E-11, 12, 13 and 14. These tables include data for four age groups and seven organs.

July 2018

CY-BR-170-301 Revision 10 Page 29 of 353 The equations used for radioactivity concentration on vegetation and in milk, and meat are discussed in Appendix A.

4.3 LIQUID RELEASES The evaluation of dose due to releases of radioactivity in liquid effluents is required to confirm compliance with the provisions of RETS related to 10CFR50 Appendix I. ODCM Section 3.2 and Figure 3-1 list some of the pathways by which radioactivity in liquid effluents can impact man. The pathways used by Exelon Nuclear to calculate dose from liquid effluents are ingestion by drinking water and by eating fish from the body of water receiving station liquid discharges. The nuclear power stations obtain the dose commitment due to radioactivity in liquid effluent releases by summing the dose commitments from the drinking water and fish pathways depending upon their presence.

Equations A-17 through A-20 of Appendix A are used to calculate dose for the member of the public due to consumption of drinking water and fish.

The radioactivity concentration in water is obtained by dividing the quantity of radioactivity released by the volume of water in which the release is diluted. The result can be modified by a factor to represent any additional dilution that might occur.

The radioactivity concentration in fish is the product of the radioactivity concentration in water and a bioaccumulation factor. The dilution factors for fish may be different from those for water. (The fish may be caught at a location different from where drinking water is drawn.)

The bioaccumulation factor accounts for the fact that the quantity of radioactivity in fish can build up with time to a higher value relative to the concentration of the radioactivity in the water they consume. The bioaccumulation factor is the equilibrium ratio of the concentration of radionuclide i in fish to its concentration in water. The same values are used for the bioaccumulation factor at each station. These values are provided in Appendix C, Table C-8.

4.4 CONTAINED SOURCES OF RADIOACTIVITY In addition to the total body, skin and single organ dose assessments previously described, an additional assessment is required. The additional assessment addresses radiation dose due to radioactivity contained within the nuclear power station and its structures.

There are presently two types of contained sources of radioactivity which are of concern in offsite radiological dose assessments. The first is that due to gamma rays resulting from nitrogen-16 carry- over to the turbine in BWR steam (skyshine). The second is that due to gamma rays associated with radioactive material contained in onsite radwaste and radioactive material storage facilities .

4.4.1 BWR Skyshine The most significant dose component to members of the public produced by "contained sources" is nitrogen-16

{1 6 N) within the turbine building of BWRs. Although primary side shielding is around the turbine and its piping, 16N gamma rays scattered by air molecules in the overhead air space above the turbine and piping cause a measurable "skyshine" radiation dose in the local power plant environs.

Equation A-23 of Appendix A is used to evaluate skyshine dose. A complicating factor in the calculation is the practice at some stations of adding hydrogen to reactor coolant to improve coolant chemistry. The addition of hydrogen can increase the dose rate due to skyshine up to a factor of 10 times expected levels depending on injection rates and power levels (Reference 39). Increasing the hydrogen injection rate will increase the dose rates even further. (See Reference 102) The skyshine dose determined by Equation A-23 of Appendix A depends on the following factors:

• The distance of the dose recipient location from the turbine.

• The number of hours per year that the location is occupied by a dose recipient.

July 2018

CY-BR-170-301 Revision 10 Page 30 of 353

• The total energy [MWe-hr] generated by the nuclear power station with hydrogen addition.

• The total energy [MWe-hr] generated by the nuclear power station without hydrogen addition.

4.4.2 Onsite Radwaste and Rad Material Storage Facilities Low-level radioactive waste may be stored at any Exelon Nuclear nuclear power station in the following types of storage facilities:

• Process Waste Storage Facilities

• Interim Radwaste Storage Facility (IRSF) structure

• Concrete vaults containing 48 radwaste liners (Also referred to as "48-pack";)

• DAW Storage Facilities

• Dry Active Waste (DAW) facilities (may include Butler buildings/warehouses)

• Replaced Steam Generator Storage Facilities Rad Material may be stored in facilities on site

• Rad Material Storage Facilities

• Contaminated tools and equipment in seavans and/or warehouses Spent Fuel may be stored in facilities on site:

• ISFSI Facilities

• Independent spent fuel storage installation facilities Administrative controls are implemented by each station to ensure compliance to applicable regulations. The impact to the offsite dose will be evaluated on a case by case basis and added to the station annex of the ODCM when applicable. In addition, a 10CFR50.59 analysis may be required for radwaste storage facilities.

4.5 TOTAL DOSE REQUIREMENTS 4.5.1 Total Effective Dose Equivalent Limits; 10CFR20 and 40CFR190 10CFR20 requires compliance to dose limits expressed as "Total Effective Dose Equivalent" (TEDE). Although annual dose limits in 10CFR20 are now expressed in terms of TEDEs, 40CFR190 limits remain stated as organ dose. The NRC continues to require 10CFR50 Appendix I and 40CFR190 doses to be reported in terms of organ dose and not TEDE. Due to the fact that organ dose limits set forth in 40CFR190 are substantially lower than those of 10CFR20 (25 mrem/yr vs 100 mrem/yr), the NRC has stated that demonstration of compliance with the dose limits in 40CFR190 will be deemed as demonstration of compliance with the dose limits of 10CFR20 for most facilities (Reference 104). In addition to compliance with 40CFR190, it may be necessary for a nuclear power plant to address dose from on-site activity by members of the public.

This control is provided to meet the dose limitations of 40CFR190 that have been incorporated into 10CFR Part 20 by 46CFR18525, as well as the dose limitations specific to Independent Spent Fuel Storage Installations (ISFSI) operations in accordance with 10CFR72.104. Over the long term, as more storage modules containing dry shielded canisters of spent fuel are placed on the ISFSI pad, it is expected that ISFSI operations will become the prominent contributor to the dose limits in this section. ISFSI dose contribution is in the form of direct radiation as no liquid or gas releases are expected to occur from the ISFSI canisters. The 10CFR72.212 Report prepared in accordance with 10CFR72 requirements assumes a certain array of storage modules exits on the pad. The dose contribution from this array of casks combination with historical uranium fuel cycle operations prior to ISFSI operations was analyzed to be within the 40CFR190 and 10CFR72.104 limits. If the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrem to the whole body or organ, except the thyroid, which shall be limited to less than or equal to 75 mrem than preparation and submittal of a Special Report is required.

CY-BR-170-301 Revision 10 Page 31 of 353 4.5.2 Total Dose For Uranium Fuel Cycle The nuclear power stations are required to determine the total dose to a member of the public due to all uranium fuel cycle sources in order to assess compliance with 40CFR190 as part of demonstrating compliance with 10CFR20.

The total dose for the uranium fuel cycle is 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. When evaluation of total dose is required for a station, the following contributions are summed:

• Doses due to airborne and liquid effluents from the station.

• Doses due to liquid effluents from nuclear power stations upstream.

• Doses due to nitrogen-16 {1 N) skyshine, ifthe station is a boiling water reactor.

• Doses due to any onsite radioactive waste storage facilities;, if applicable.

Section A.5.2 of Appendix A discusses the details of evaluations.

CY-BR-170-301 Revision 10 Page 34 of 353 CHAPTERS MEASUREMENT

5.0 INTRODUCTION

Each nuclear station has three measurement programs associated with offsite dose assessment:

• Measurement of releases of radioactivity from the station.

• Measurement of meteorology at the station site.

• Measurement of levels of radiation and radioactivity in the environs surrounding the station.

5.1 EFFLUENT AND PROCESS MONITORING Radioactivity in liquid and gaseous effluents is measured in order to provide data for calculating radiation doses and radioactivity concentrations in the environment of each nuclear power station. Measurement of effluent radioactivity is required by 10CFR20.1302 and 10CFR50. The RETS of each nuclear power station provide detailed requirements for instrumentation, sampling and analysis. Relevant Regulatory Guides are 1.21 (Reference 4) and 4.15 (Reference 13). Chapter 10 of the ODCM includes brief descriptions of effluent monitoring instruments at each nuclear power station. The RETS of each nuclear power station require submission to the NRC of reports of effluent radioactivity releases and environmental measurements.

5.2 METEOROLOGICAL MONITORING Meteorological parameters are measured in the vicinity of each nuclear power station in order to provide data for calculating radiation doses due to airborne effluent radioactivity. Some nuclear power stations' Technical Specifications state applicable requirements (typically under the subheading, "Meteorological Instrumentation," in the instrumentation section). Regulatory guidance is given in Regulatory Guide 1.23 (Reference 5). Wind speed, wind direction and the temperature gradient are measured using instruments at two or more elevations on a meteorological tower at each Exelon Nuclear station. The elevations are chosen to provide meteorological data representative of the elevations of the airborne releases from the station. The Annual Radiological Environmental Operating Report includes a summary of meteorological data collected over the reporting year. These data are used to calculate optional isopleths of radiation dose and radioactivity concentration.

5.3 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP)

Each nuclear power station has a REMP that provides representative measurements of radiation and radioactive material in the environment. The program provides verification that measurable radiological impacts from the power station on the environment are within expectations derived from effluent measurements and calculations.

The REMP is required by 10CFRSO (see Appendix I, Sections IV.B.2 and IV.B.3). General requirements of the program are prescribed in each station's RETS and more precise details (such as specific monitoring locations) are specified in ODCM Chapter 11.

5.3.1 lnterlaboratory Comparison Program The laboratory which performs the REMP analyses is required by the RETS to participate in an interlaboratory comparison program. The purpose is to provide an independent check on the laboratory's analytical procedures and to alert it to potential problems (e.g. accuracy). In order to assess the measurements of radioactivity in environmental media, an independent agency supplies participating laboratories with samples of environmental media containing unspecified amounts of radioactivity. The laboratories measure the radioactivity concentrations and report the results to the agency. At a later time, the agency informs the participating laboratories of the actual concentrations and associated uncertainties. Any significant discrepancies are investigated by the participating laboratories. A similar process is used to assess measurements of environmental radiation by passive dosimeters.

July 2018

CY-BR-170-301 Revision 10 Page 35 of 353 CHAPTERS IMPLEMENTATION OF OFFSITE DOSE ASSESSMENT PROGRAM 6.1 NUCLEAR POWER STATION The nuclear power station staff is responsible for effluent monitoring. The staff determines effluent radioactivity concentration and flow rate. These data are used to determine the radioactivity release information required for the Radioactive Effluent Release Report and to perform monthly calculations and projections of offsite radiation dose.

The nuclear power station staff is also responsible for control of effluent radioactivity. Procedures are implemented for determining, calculating and implementing setpoints. Liquid and gaseous radwaste treatment systems and ventilation exhaust treatment systems are utilized when appropriate. The nuclear power station staff implements the Process Control Program (PCP) for solid radwaste and measures tank radioactivity and BWR off-gas radioactivity.

The nuclear power station staff maintains instrumentation associated with these activities and demonstrates operability of the instrumentation in accordance with the surveillance requirements of the RETS. In the event that any RETS requirements are violated, the nuclear power station staff is responsible for taking one of the actions allowed by the RETS and issuing any required reports to the NRC.

The nuclear power station staff assembles and distributes the Annual Radioactive Effluent Release Report including a summary of the quantities of radioactive liquid and gaseous effluents and solid waste released from the facility as outlined in Regulatory Guide 1.21, "Measuring, Evaluations, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants, "Revision 1, June 1974, with data summarized on a quarterly basis following the format of Appendix B.

The Annual Radioactive Effluent Release Report shall also 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 (including doses from primary effluent pathways and direct radiation) for the previous calendar year.

6.2 METEOROLOGICAL CONTRACTOR The meteorological contractor operates and maintains the meteorological tower instrumentation at each nuclear power station. The contractor collects and analyzes the data and issues periodic reports. The contractor prepares the meteorological data summary required for the Annual Radiological Environmental Operating Report (AREOR) and also computes and plots isopleths included in the AREOR.

6.3 REMP CONTRACTOR The radiological environmental contractor collects environmental samples and performs radiological analyses as specified in the nuclear power station's REMP (see ODCM Chapters 11 and 12). The contractor issues reports of results to appropriate points of contact and each nuclear station. The contractor participates in an interlaboratory comparison program and reports results in the Annual Radiological Environmental Operating Report. The contractor performs the annual land use census and assembles the Annual Radiological Environmental Operating Report.

CY-BR-170-301 Revision 10 Page 45 of 353 APPENDIX A COMPLIANCE METHODOLOGY A.O INTRODUCTION This appendix reviews the offsite radiological limits applicable to the nuclear power stations and presents in detail the equations and procedures used to assess compliance with these limits. An introduction to the calculation approach used here is given in Chapter 4. The approach incorporates simplifications such as the following:

• Use of pre-calculated atmospheric transport parameters based on historical average atmospheric conditions (see Section 4.1.5). These atmospheric dispersion and deposition factors are defined in Chapter 4.

The equations and parameters of this appendix are for use in calculating offsite radiation doses during routine operating conditions. They are not for use in calculating doses due to non-routine releases (e.g., accident releases).

This section of the ODCM provides the methodological details for demonstrating compliance with the 10CFR20, 10CFR50 Appendix I and 40CFR190 radiological limits for liquid and gaseous effluents.

An overview of the required compliance is given in Tables 2-1, 2-2, and 2-3. In Table 2-1, the dose components are itemized and referenced, and an indication of their regulatory application is noted. A more detailed compliance matrix is given in Table 2-3. Additionally, the locations of dose receivers for each dose component are given in Table 2-2.

The following sections detail the required radiological dose calculations.

A.1 AIRBORNE RELEASES A.1.1 Release Point Classifications The pattern of dispersion of airborne releases is dependent on the height of the release point relative to adjacent structures. For the equations of this appendix, each release point is classified as one of the following three height-dependent types, which are defined in Section 4.1.4:

• Stack (or Elevated) Release Point (denoted by the letter Sor subscripts)

• Ground Level Release Point (denoted by the letter G or subscript g)

• Vent (or Mixed Mode) Release Point (denoted by the letter V or subscript v)

The release point classifications of routine release points at the nuclear power stations are stated in Table A-2.

Measured release rate of radionuclide i from a stack, vent or ground level release point, respectively.

All other terms have been previously defined.

Application RETS require the dose rate due to noble gases in gaseous effluents be determined to be within the above limit in accordance with methodology specified in the ODCM (see Section 12.4 of each station's RETS and Technical Specifications).

To comply with this specification, each station uses an effluent radiation monitor setpoint corresponding to an offsite total body dose rate at or below the limit (see Chapter 10). In addition, each station assesses compliance by calculating offsite total body dose rate on the basis of periodic samples obtained in accordance with station procedures.

A.1.3.2 Skin Dose Rate Requirement RETS limit the skin dose rate due to noble gases in gaseous effluents released from a site to areas at and beyond the site boundary to less than or equal to a dose rate of 3000 mrem/yr at all times.

July 2018

CY-BR-170-301 Revision 10 Page 51 of 353 Application RETS require the dose rate due to noble gases in gaseous effluents to be determined to be within the above limit in accordance with methodology specified in the ODCM. (See Section 12.4 of each station's RETS and Technical Specifications.)

To comply with this specification, each station uses an effluent radiation monitor setpoint corresponding to an offsite skin dose rate at or below the limit (see Chapter 10). In addition, each station assesses compliance by calculating offsite skin dose rate on the basis of samples obtained periodically in accordance with station procedures.

A.1.4 Dose Due to Non-Noble Gas Radionuclides Requirement RETS provide the following limits, based on 10CFR50 Appendix I, on the dose to a member of the public from specified non-noble gas radionuclides in gaseous effluents released from each reactor unit to areas at and beyond the unrestricted area boundary:

• Less than or equal to 7.5 mrem to any organ during any calendar quarter.

• Less than or equal to 15 mrem to any organ during any calendar year.

The individual dose components are also required as part of the 40CFR190 assessments and combined as part of the 10CFR20 assessment (See Section A.4). The dose due to radionuclides deposited on the ground is considered to be a component of the deep dose equivalent for 10CFR20 compliance and an organ (and total body) dose component for 10CFR50 Appendix I and 40CFR190 compliance.

In accordance with the definition of dose in Regulatory Guide 1.109, the term "dose" in this document when applied to individuals, is used instead of the more precise term "dose equivalent," as defined by the International Commission on Radiological Units and Measurements (ICRU). When applied to the evaluation of internal deposition of radioactivity, the term "dose" as used here, includes the prospective dose component arising from retention in the body beyond the period of environmental exposure, i.e., the dose commitment. The dose commitment is evaluated over a period of 50 years. Assessments for 10CFR50 Appendix I compliance are made for 4 age groups (adult/teenager/child/infant) using Regulatory Guide 1.109 (Reference 6) dose conversion factors.

Equation The dose is calculated for releases in the time period under consideration.

Specifically, the dose is calculated as follows:

D~JNG = (3.17E-8)LL[wsRaipjAis + WvRalpjAiv + WgRalp]Alg] (A-7) p I The summation is over pathways p and non-noble gas radionuclides i.

Application RETS require cumulative and projected dose contributions for the current calendar quarter and the current calendar year for the specified non-noble gas radionuclides in airborne effluents to be determined at least once per 31 days (see Section 12.4 of each station's RETS and Technical Specifications).

To comply with this specification, each nuclear power station obtains and analyzes samples in accordance with the radioactive gaseous waste or gaseous effluent sampling and analysis program in its RETS. In accordance with NUREG 0133 (Reference 14), dose due to non-noble gases is assessed at the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates the maximum potential exposure. The inhalation and ground plane exposure pathways are considered to exist at all locations. The food ingestion pathways at a specific location are considered based on their existence as determined by land use census. The values used for (x/0) and (D/Q) correspond to the applicable pathway location.

For a release attributable to a processing or effluent system shared by more than one reactor, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. The allocation procedure is specified in ODCM Chapter 10.

The dose evaluated is also included as .part of the 10CFR20 and 40CFR190 assessment (See Section A.4).

To comply with this specification, each station obtains and analyzes samples in accordance with the sampling and analysis program in its RETS. The child organ dose rate due to inhalation is calculated in each sector at the location of the highest offsite x!Q. The result for the sector with the highest organ inhalation dose rate is compared to the limit.

July 2018

CY-BR-170-301 Revision 10 Page 61 of 353 A.1.6 Operability and Use of Gaseous Effluent Treatment Systems Requirement 10CFR50 Appendix I and the station RETS require that the ventilation exhaust treatment system and the waste gas holdup system be used when projected offsite doses in 31 days, due to gaseous effluent releases, from each reactor unit, exceed any of the following limits:

• 0.2 mrad to air from gamma radiation.

• 0.4 mrad to air from beta radiation.

• 0.3 mrem to any organ of a member of the public.

The nuclear power stations are required to project doses due to gaseous releases from the site at least once per 31 days.

Equation Offsite doses due to projected releases of radioactive materials in gaseous effluents are calculated using Equations A-1, A-2 and A-7. Projected cumulative radionuclide releases are used in place of measured cumulative releases Ais* Aiv and Aig* A dose projection is performed at least once per 31-days using the following equations:

July 2018

CY-BR-170-301 Revision 10 Page 62 of 353 A.2 LIQUID RELEASES A.2.1 Dose Requirement The design objectives of 10CFR50, Appendix I and RETS provide the following limits on the dose to a member of the public from radioactive materials in liquid effluents released from each reactor unit to restricted area boundaries:

During any calendar quarter, less than or equal to 1.5 mrem to the total body and less than or equal to 5 mrem to any organ.

During any calendar year, less than or equal to 3 mrem to the total body and less than or equal to 1O mrem to any organ.

The organ doses due to radioactivity in liquid effluents are also used as part of the 40CFR190 compliance and are included in the combination of doses to determine the total dose used to demonstrate 10CFR20 compliance.

(See Section A.4)

Dose assessments for 10CFR50 Appendix I compliance are made for four age groups (adult/teenager/child/infant) using NUREG 0133 (Reference 14) methodology and Regulatory Guide 1.109 (Reference 6) dose conversion factors.

Equation The dose from radioactive materials in liquid effluents considers the contributions for consumption of fish and potable water. All of these pathways are considered in the dose assessment unless demonstrated not to be present. While the adult is normally considered the maximum individual, the methodology provides for dose to be calculated for all four age groups. The dose to each organ (and to the total body) is calculated by the following expression:

Application RETS require determination of cumulative and projected dose contributions from liquid effluents for the current calendar quarter and the current calendar year at least once per 31 days. (see Section 12.3 of each station's RETS and/or Technical Specifications).

For a release attributable to a processing or effluent system shared by more than one reactor unit, the dose due to an individual unit is obtained by proportioning the effluents among the units sharing the system. The allocation procedure is specified in ODCM Chapter 10.

A.2.2 Liquid Effluent Concentrations Requirement Requirement One method of demonstrating compliance to the requirements of 10CFR20.1301 is to demonstrate that the annual average concentrations of radioactive material released in gaseous and liquid effluents do not exceed the values specified in 10CFR20 Appendix B, Table 2, Column 2. (See 10CFR 20.1302(b)(2).) However, as noted in Section A.5.1, this mode of 10CFR20.1301 compliance has not been elected.

As a means of assuring that annual concentration limits will not be exceeded, and as a matter of policy assuring that doses by the liquid pathway will be ALARA; RETS provides the following restriction:

"The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to ten times the concentration values in Appendix B, Table 2, Column 2 to 10CFR20.1001-20.2402."

This also meets the requirement of Station Technical Specifications and RETS.

July 2018

CY-BR-170-301 Revision 10 Page 65 of 353 Equation According to the footnotes to 10CFR20 Appendix B, Table 2, Column 2, if a radionuclide mix of known composition is released, the concentrations must be such that (A-21) where the summation is over radionuclide i.

This concentration is specified in 10CFR20 Appendix B, Table 2; Column 2. Concentrations for noble gases are different and are specified in the stations' Technical Specifications/RETS.

10 Multiplier to meet the requirements of Technical Specifications.

If either the identity or concentration of any radionuclide in the mixture is not known, special rules apply. These are given in the footnotes in 10CFR20 Appendix B, Table 2, Column 2.

Application The RETS and Technical Specifications require a specified sampling and analysis program to assure that liquid radioactivity concentrations at the point of release are maintained within the required limits.

To comply with this provision, each nuclear power station obtains and analyzes samples in accordance with the radioactive liquid waste (or effluent) sampling and analysis program in its RETS. Radioactivity concentrations in tank effluents are determined in accordance with Equation A-22 in the next section. Comparison with the Effluent Concentration Limit is made using Equation A-21.

A.2.3 Tank Discharges When radioactivity is released to the unrestricted area with liquid discharge from a tank (e.g., a radwaste discharge tank), the concentration of a radionuclide in the effluent is calculated as follows:

C. = C~ Waste Flow (A-22)

' Dilution Flow C; Concentration in Liquid effluent to the unrestricted area. [µCi/ml]

Concentration of radionuclide i in liquid released to the unrestricted area.

July 2018

CY-BR-170-301 Revision 10 Page 66 of 353 A.2.4 Tank Overflow Requirement To limit the consequences of tank overflow, the RETS/Technical Specifications may limit the quantity of radioactivity that may be stored in unprotected outdoor tanks. Unprotected tanks are tanks that are not surrounded by liners, dikes, or walls capable of holding the tank contents and that do not have tank overflows and surrounding area drains connected to the liquid radwaste treatment system. The specific objective is to provide assurance that in the event of an uncontrolled release of a tank's contents, the resulting radioactivity

• concentrations beyond the unrestricted area boundary, at the nearest potable water supply and at the nearest surface water supply, will be less than the limits of 10CFR20 Appendix B, Table 2; Column 2.

The Technical Specifications and RETS may contain a somewhat similar provision. For most nuclear power stations, specific numerical limits are specified on the number of curies allowed in affected tanks.

Application Table F-1 of Appendix F provides information on the limits applicable to affected stations. The limits are as stated for some stations in the station Technical Specifications.

A.2.5 Operability and Use of the Liquid Radwaste Treatment System Requirement The design objectives of 10CFR50, Appendix I and RETS/Technical Specifications require that the liquid radwaste treatment system be operable and that appropriate portions be used to reduce releases of radioactivity when projected doses due to the liquid effluent from each reactor unit to restricted area boundaries exceed either of the following (see Section 12.3 of each station's RETS or Technical Specifications);

0.06 mrem to the total body in a 31 day period.

0.2 mrem to any organ in a 31 day period.

Equation Offsite doses due to projected releases of radioactive materials in liquid effluents are calculated using Equation A-

17. Projected radionuclide release concentrations are used in place of measured concentrations, Ci. A dose projection is performed at least once per 31-days using the following equations:

July 2018

CY-BR-170-301 Revision 10 Page 67 of 353 A.2.6 Drinking Water Five nuclear power stations (Braidwood, Dresden, LaSalle, and Quad Cities) have requirements for calculation of drinking water dose that are related to 40CFR 141, the Environmental Protection Agency National Primary Drinking Water Regulations. These are discussed in Section A.6.

A.2.7 Non-routine Liquid Release Pathways Cases in which normally non-radioactive liquid streams (such as the Service Water) are found to contain radioactive material are non-routine will be treated on a case specific basis if and when this occurs. Since each station has sufficient capacity to delay a liquid release for reasonable periods of time, it is expected that planned releases will not take place under these circumstances. Therefore, the liquid release setpoint calculations need not and :do not contain provisions for treating multiple simultaneous release pathways.

July 2018

CY-BR-170-301 Revision 10 Page 68 of 353 A.3 DOSE DUE TO CONTAINED SOURCES There are presently two types of contained sources of radioactivity which are of concern in Exelon Nuclear offsite 6

radiological dose assessments. The first source is that due to gamma rays from nitrogen-16 {1 N) carried over to the turbine in BWR (boiling water reactor) steam. The second source is that due to gamma rays associated with radioactive material resident in onsite radwaste storage facilities. Gamma radiation from these sources contributes to the total body dose.

A.3.1 BWR Skyshine The contained onsite radioactivity source which results in the most significant offsite radiation levels at Exelon 16 Nuclear nuclear power stations is skyshine resulting from N decay inside turbines and steam piping at boiling water reactor (BWRs).

The N that produces the skyshine effect is formulated through neutron activation of the oxy~en atoms (oxygen-16 16 6 16, or 0) in reactor coolant as the coolant passes through the operating reactor core. The N travels with the 16 steam produced in the reactor to the steam driven turbine. While the N is in transport, it radioactively decays with a half-life of about 7 seconds and produces 6 to 7 MeV gamma rays. Typically, offsite dose points are 16 shielded from a direct view of components containing N, but there can be skyshine radiation at offsite locations due to scattering of gamma rays off the mass of air above the steamlines and turbine.

The offsite dose rate due to skyshine has been found to have the following dependencies:

• The dose rate decreases as distance from the station increases.

• The dose rate increases non-linearly as the power production level increases.

• The dose rate increases when hydrogen is added to the reactor coolant, an action taken to improve reactor coolant chemistry characteristics (see Reference 39).

To calculate offsite dose due to skyshine in a given time period, a BWR must track the following parameters:

• The total gross energy Eh produced with hydrogen being added.

• The total gross energy E0 produced without hydrogen being added.

The turbines at BWR sites are sufficiently close to each other that energy generated by the two units at each site may be summed.

An initial estimate of BWR skyshine dose is calculated per the following equation:

D5kY =(K)(E +MhEh)L {OFk SFk e-0.oo7Rk}

0 (A-23) k The summation is over all locations k occupied by a hypothetical maximally exposed member of the public characterized by the parameters specified in Table F-8 of Appendix F of the Dresden, LaSalle, and Quad Cities ODCMs. The parameters in Equation A-23 are defined as follows:

DSky Dose Due to N-16 Skyshine [mrem]

External direct gamma dose due to BWR N-16 skyshine for the time period of interest.

K Empirical Constant [mrem/(MWe-hr)]

A constant determined by fitting data measured at each station.

Total gross electrical energy generated without hydrogen addition in the time period of interest.

Electrical Energy Generated with Hydrogen Addition [MWe-hr]

Total gross electrical energy generated with hydrogen addition in the period of interest.

Multiplication Factor for Hydrogen Addition dimensionless Factor applied to offsite dose rate when skyshine is present. Hydrogen addition increases main steam line radiation levels typically up to a factor of approximately 5 (see Page 8-1 of Reference 39). Mh is station specific and is given in Table F-8, Appendix F of Dresden, LaSalle and Quad Cities ODCMs.

Occupancy Factor dimensionless The fraction of time that the dose recipient spends at location k during the period of interest. See Table F-8, Appendix F of Dresden, LaSalle and Quad Cities ODCMs.

Shielding Factor dimensionless A dimensionless factor that accounts for shielding due to occupancy of structures.

SFk =0. 7 if there is a structure at location k; SFk =1.0 otherwise. See Table F-8, Appendix F of Dresden, LaSalle and Quad Cities ODCMs.

0.007 Empirical Constant A constant determined by fitting data measured at the Dresden station (see Reference 45).

Distance [m]

Distance from the turbine to location k. See Table F-8, Appendix F of Dresden, LaSalle and Quad Cities ODCMs.

A.3.2 Dose from Onsite Radwaste Storage Facilities Low-level radioactive waste may be stored at any, or all Exelon Nuclear nuclear power stations in the following types of storage facilities:

• Interim Radwaste Storage Facility (IRSF)

• Concrete vaults containing 48 radwaste liners (48-Pack)

• Dry Active Waste (DAW) facilities

• Butler buildings/warehouses

• Steam generator storage facilities

• Independent Spent Fuel Storage Installation (ISFSI) facilities The "48-Pack" is a shielded concrete vault which is designed to hold three tiers of radwaste liners in a four by four array. The outer shell of the "48-Pack" is a three-foot thick concrete wall and a two and one-half foot thick concrete cover slab. The vault is placed on a poured concrete slab. The liners may have an average surface dose rate of fifteen (15) rem per hour (or up to 380 rem/hr if a 50.59 evaluation has been completed).

July 2018

CY-BR-170-301 Revision 10 Page 70 of 353 The DAW facility will contain low-level radioactive waste that would result in dose rates less than the 10CFR20 requirements.

The dose rates resulting from these radwaste and spent fuel storage facilities will be monitored frequently as they are being utilized, and if necessary, a dose calculation model similar to that of Equation A-23 will be developed and placed in the ODCM.

A.4 Total Dose Limits (10CFR20, 40CFR190 and 10CFR72.104)

The regulatory requirements of 10CFR20, 40CFR190 and 10CFR72.104 each limit total dose to individual members of the public without regard to specific pathways. The only significant exposure pathways for light water reactors included in 10CFR20 and 40CFR190 not addressed by 10CFR50 Appendix I are the direct radiation pathway and exposure from on-site activity by members of the public. Sections A.1 and A.2 considered organ doses from the gaseous and liquid effluent streams for purposes of compliance with 10CFR50 Appendix I.

Section A.3 addresses the direct radiation. component that must be considered for 10CFR20 and 40CFR1.90 compliance. The following sections will describe the methodology of assessing direct radiation dose and then the manner in which the various doses are combined to obtain the appropriate "total" for regulatory compliance purposes.

Although annual dose limits in 10CFR20 are now expressed in terms of Total Effective Dose Equivalent (TEDE) 40CFR190 limits are still stated as organ dose. The NRC continues to require 10CFR50 Appendix I and 40CFR190 doses to be reported in terms of organ dose. Due to the fact that organ dose limits set forth in 40CFR190 are substantially lower than those of 10CFR20 (25 mrem/yr vs. 100 mrem/yr), the NRC has stated that demonstration of compliance with the dose limits in 40CFR190 will be deemed as demonstration of compliance with the dose limits of 10CFR20 for most facilities (Reference 104). In addition to compliance with 40CFR190 it may be necessary for a nuclear power plant to address dose from on-site activity by members of the public.

A.4.1 External Total Body Dose The external total body dose is comprised of the following parts:

1) Total body dose due to noble gas radionuclides in gaseous effluents (Section A.1.2),

2) Dose due to N-16 skyshine and other contained sources (Sections A.3.1 and A.3.2) and

3) Total body dose due to radioactivity deposited on the ground (Section A.1.4.1 ).

The external total body dose due to radioactivity deposited on the ground is accounted for in the determination of the non-noble gas dose (See Equations A-7 and A-8) and is not considered here.

The total external total body dose, DEx, is given by:

DEX= DTB + DSky + DOSF (A-24)

Total External Total Body Dose [mrem]

Total external total body dose due to irradiation by external sources at the location of interest.

A.4.2 Total Dose The total dose, DTot, in the unrestricted area to a member of the public due to plant operations is given by:

(A-25) where:

DTot Total Dose To Member of Public [mrem]

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

Total External Total Body Dose [mrem]

D~NG 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.

A.5 COMPLIANCE TO TOTAL DOSE LIMITS A.5.1 Total Effective Dose Equivalent Limit -10CFR20 Compliance Requirement Each station's RETS limits the Total Effective Dose Equivalent (TEDE) to an annual limit of 100 mrem, as required by 10CFR20.1301 (a)(1 ). Demonstration of compliance with the limits of 40CFR190 (per Section 4.5.2) will be considered to demonstrate compliance with the 100 mrem/year limit.

A.5.1.1 Dose to a Member of the Public in the Unrestricted Area The NRC has stated that demonstration of compliance with the limits of 40CFR 190 and 10CFR72.104 or with the design objectives of Appendix I to 10CFR50 will be deemed to demonstrate compliance with the limits of 10CFR20.1301 (a)(1 ). Power reactors that comply with Appendix I may also have to demonstrate that they are within the 25 mrem limit of 40CFR190 and 10CFR72.104.

July 2018

CY-BR-170-301 Revision 10 Page 72 of 353 A.5.1.2. Dose to a Member of the Public in the Restricted Area In August of 1995, a revision to 10CFR20 was implemented that changed the definition of a member of the public.

As a result, for each nuclear station, estimated doses were calculated for a member of the public who enters the site boundary, but is not authorized for unescorted access to the protected area of the site and does not enter any radiologically posted areas on the site. Realistic assumptions were made for occupancy times and locations visited while within the site boundary.

These evaluations indicate that the doses estimated for these members of the public are well within the 10CFR20 limits. These dose evaluations will be performed annually and if necessary, a model will be developed and included in the ODCM.

Application Evaluation of the 40CFR190 and 10CFR72.104 dose is used to demonstrate compliance to 10CFR20 and satisfy station RETS and Technical Specifications (see Chapter 12).

A.5.2 Total Dose due to the Uranium Fuel Cycle (40CFR190)

Requirement RETS, 40CFR190 and 10CFR72.104 limit the annual (calendar year) dose or dose commitment to any member of the public due to releases of radioactivity and to radiation from uranium fuel cycle sources to the following:

• Less than or equal to 25 mrem to the total body.

• Less than or equal to 25 mrem to any organ except the thyroid.

• Less than or equal to 75 mrem to the thyroid.

Total Dose Components This requirement includes the total dose from operations at the nuclear power station.

CY-BR-170-301 Revision 10 Page 73 of 353 When Compliance Assessment is Required:

Compliance with the 40CFR190 regulations is now required as part of demonstration of compliance to 10CFR20 regulations per 10CFR20.1301 (d).

Equation The dose due to the uranium fuel cycle is determined by equation A-25.

A.5.3 Summary of Compliance Methodology The required compliance is given in Tables 2-1, 2-2 and 2-3. In Table 2-1, the dose components are itemized and referenced, and an indication of their regulatory application is noted. A more detailed compliance matrix is given in Table 2-3. The locations of dose receivers for each dose component are given in Table 2-2.

I i i Further, Table 2-2 states the location of the receiver and occupancy factors, if applicable. In general, the receiver spends time in locations that result in maximum direct dose exposure and inhales and ingests radioactivity from sites that yield maximum pathway doses. Thus, the dose calculated is a very conservative one compared to the "average" receiver who does not go out of his way to maximize radioactivity uptakes. Finally, the connection between regulations, the ODCM equations and the station RETS and Technical Specifications is given in Table 12-0.

A.6 DOSE DUE TO DRINKING WATER (40CFR141)

The National Primary Drinking Water Regulations, 40CFR141, contain the requirements of the Environmental Protection Agency applicable to public water systems. Included are limits on radioactivity concentration.

Although these regulations are directed at the owners and operators of public water systems, several stations have requirements in their Technical Specifications related to 40CFR141.

A.6.1 40CFR141 Restrictions on Manmade Radionuclides Section 141.16 states the following (not verbatim):

(a) The average annual concentration of beta particle and photon radioactivity from man-made radionuclides in drinking water shall not produce an annual dose equivalent to the total body or any internal organ greater than 4 millirem/year.

(b) Except for the radionuclides listed in Table A-0, the concentration of man-made radionuclides causing 4 mrem total body or organ dose equivalents shall be calculated on the basis of drinking 2 liter of water per day. (Using the 168 hour0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> data listed in "Maximum Permissible Body Burdens and Maximum Permissible Concentration of Radionuclides in Air or Water for Occupational Exposure, "NBSHandbook 69 as amended August 1963, U.S. Department of Commerce.). If two or more radionuclides are present, the sum of their annual dose equivalents to the total body or any organ shall not exceed 4 millirem/year.

Projections are made using projected radionuclide releases in place of measured releases A;. Doses calculated using Equations A-17 and A-19 may differ from doses determined by the methodology prescribed in 40CFR141.16.

When required, a nuclear power station prepares a special report on radiological impact at the nearest community water system. This system is taken as the one listed in Table A-3 of this appendix. The report should include the following:

• The doses calculated by Equations A-17 and A-19.

• A statement identifying the dose calculation methodology (e.g., a reference to this manual).

• A statement that the doses calculated by the ODCM methodology are not necessarily the same as doses calculated by the methodology prescribed in 40CFR 141.16.

• The data used to calculate the doses. This information includes the amounts of radioactivity released and the flow rate and dilution values used (see Table F-1). This information is provided to assist the operator of the community water system in performing its own dose assessment.

8.0 INTRODUCTION

The equations used for calculation of doses due to radioactive airborne effluents are given in Section A.1 of Appendix A. The equations involve the following types of parameters:

• Meteorological Parameters These include x!Q, gammct-x/Q, D/Q and wind speed. Their values are based on historical average atmospheric conditions at a site for a selected multi-year historical period (see Section 4.1.5).

• Dose Factors These parameters are used to provide a simple way to calculate doses and dose rates due to gamma and beta radiation. These parameters are independent of meteorological conditions and therefore generic (i.e., not station-specific).

• Measured Release Parameters These are measured values of radioactivity releases and release rates.

• Radiological Decay Constants These are used to account for the radioactive decay between the release of radioactivity to the environment and the exposure of persons to it.

• Production/Exposure Parameters These are parameters characterizing agricultural production (e.g., length of growing season, transport times) and human exposure patterns (e.g., exposure period, breathing rate, food consumption rates).

These parameters affect the quantities of radioactivity to which persons may be exposed.

This appendix discusses the methodology used to determine values of these parameters. Section 8.1 addresses how the historical meteorology of a site is characterized by use of a function called the joint frequency distribution.

Section 8.1 and Sections 8.3 through 8.5 present equations that use the joint frequency distribution to obtain values for site-specific meteorological parameters. These equations involve a mathematical model of a plume known as the Gaussian plume model. This model is developed in Section 8.2. Various generic dose factors are discussed in Sections 8.6 through 8.10. The other parameters are discussed in the remaining sections.

8.1 METEOROLOGICAL DATA AND PARAMETERS Predicting where airborne effluent will travel requires information on the following:

• Wind speed

• Wind direction

• Atmospheric turbulence The greater the atmospheric turbulence, the more an effluent plume will tend to broaden and the more dilute the concentration will be. Atmospheric turbulence is affected by the general condition of the atmosphere (e.g., the vertical temperature distribution) and by local features (e.g., objects that protrude into the wind stream). A commonly used classification scheme for the degree of atmospheric turbulence associated with the general condition of the atmosphere involves seven stability classes:

A Extremely Unstable 8 Moderately Unstable C Slightly Unstable D Neutral E Slightly Stable F Moderately Stable G Extremely Stable July 2018

CY-BR-170-301 Revision 10 Page 83 of 353 This classification scheme is based on Reference 5, Table 1. Each class is associated with a particular range of wind direction fluctuations and of vertical temperature gradients in the atmosphere. These are specified in Table C-4 of Appendix C.

8.1.1 Data Historical atmospheric conditions at each nuclear power station were recorded by an instrumented meteorological tower that measured wind speed, wind direction, and temperature at various heights. Hourly average values of wind speed, wind direction, and stability class were determined. The difference in temperature between two heights was used to assign an atmospheric stability class based on the correlation between temperature gradient and stability class in Table C-4 of Appendix C.

In obtaining the data, quality assurance checks and corrections were made. Also, corrections were applied to compensate for the limitations of wind sensors at low speeds. A calm was said to exist if the wind speed was less than that of the threshold of either the anemometer (wind speed meter) or the wind direction vane. For calm conditions, a wind speed equal to one-half of the higher threshold was assigned. For each stability class, the wind directions during calm conditions were assumed to be distributed in proportion to the observed wind direction distribution of the lowest non-calm wind speed class.

8.1.2 Joint Frequency Distribution The data for a particular historical period are summarized by developing a joint frequency distribution (JFD).

Each such distribution specifies the fraction of time during the historical period that the following jointly occur:

• Wind speed within a particular range (wind speed class).

• Downwind direction in one of the 16 sectors corresponding to the 16 principal compass directions (N, NNE, etc.).

• Atmospheric conditions corresponding to one of the seven atmospheric stability classes discussed in Section 8.1. Table 8-1 of this appendix displays a portion of an example JFD.

Different JFDs are associated with the different release classifications defined in Section 4.1.4. One JFD is defined for stack releases, and another JFD is defined for ground level releases. Two JFDs are associated with vent (mixed mode) releases, one for the portion of the time the release is treated as elevated and the other for the portion of the time the release is treated as ground level.

8.1.2.1 Downwind Direction Versus Upwind Direction Unless otherwise noted, any reference to wind direction in this document represents downwind direction, i.e., the direction in which the wind is blowing toward. This is because the parameters developed in this document are used to calculate radioactivity concentration and radiation dose downwind of a release point. In contrast, it is conventional for meteorologists to provide JFDs based on upwind direction, the direction from which the wind is blowing. For example, the JFDs presented in the annual operating reports of the nuclear power stations are obtained from a meteorological contractor and the directions specified in the reports are upwind directions. Users of JFDs should always be careful to ascertain whether the directions specified are upwind or downwind.

July 2018

CY-8R-170-301 Revision 10 Page 84 of 353 8.1.2.2 Stack JFD For a stack release, the JFD is defined as follows:

Joint Frequency Distribution, Stack Release The fraction of hours during a period of observation that all of the following hold:

• The average wind speed is within wind speed class n.

• The downwind direction is within the sector denoted by 0.

• The atmospheric stability class is c.

This function is defined for application to a stack release point (see Section 4.1.4). Its value is based on hourly average wind data obtained at a height representative of the release point height.

The stack JFD is normalized to 1:

I: f 5 (n,0,c) = 1 (8-1)

The summation is over all wind speed classes n, all compass direction sectors 0, and all stability classes c.

8.1.2.3 Ground Level JFD For a ground level release, the JFD fg(n, 0,c) is defined in the same way as for a stack release except that the wind data are obtained at a height representative of a ground level release point. This height is taken as about 10 meters.

The ground level JFD is normalized to 1:

I: fg(n,0,c) =1 (8-2)

The summation is over all wind speed classes n, all compass direction sectors, and all stability classes c.

8.1.2.4 Vent JFDs In accordance with the approach recommended in Regulatory Guide 1.111 (Reference 7), the plume from a vent release is treated as elevated part of the time and as ground level the rest of the time. Two JFDs are determined:

• fv elev(n,0,c) characterizes the plume during the part of the time that it is considered elevated;

• fv,gnd(n,0,c) characterizes the plume during the part of the time that it is considered ground level.

Their definitions are as follows:

fv,elev(n,0,c) Joint Frequency Distribution, Elevated Portion of a Vent Release The fraction of hours during a period of observation that the plume is considered elevated and that all of the following hold:

• The average wind speed is within wind speed class n.

• The downwind direction is within the sector denoted by 0.

• The atmospheric stability class is c.

July 2018

CY-8R-170-301 Revision 10 Page 85 of 353 fv,gnd(n,9,c) Joint Frequency Distribution, Ground Level Portion of a Vent Release The fraction of hours during a period of observation that the plume is considered ground level and that all of the following hold:

• The average wind speed is within wind speed class n.

• The downwind direction is within the sector denoted bye.

• The atmospheric stability class is c.

The value of fv elev(n, e,c) is based on hourly average wind data at a height representative of the vent release point. Where the ' measurement height differed considerably from the release height, wind speed data for the release height was obtained by extrapolation. The value of fv,gnd(n, e,c) is based on hourly average wind data obtained at a height representative of a ground level release point. This is taken as about 10 meters.

• The sum of these two JFDs is normalized to 1:

.I:{ fv,elev(n, e,c) + fv,gnd(n, e,c)} = 1 (8-3)

The summation is over all wind speed classes n, all compass direction sectors e, and all stability classes c.

The prescription of Regulatory Guide 1.111 is used in determining the fraction of time that the plume is considered elevated and the fraction of time that it is considered ground level. The fractions are obtained from the ratio of stack exit velocity W 0 to hourly average wind speed u at the height of the vent release point as follows:

If W 0 /u > 5, then the plume is considered elevated for the hour.

If W 0 /u .::s. 1, then the plume is considered ground level for the hour.

If 1 < W 0 /u .::s. 5, the plume is considered to be a ground level release for a fraction Gt of the hour and an elevated release for a fraction (1 - Gt) of the hour where Gt is defined as follows:

Gt= 2.58 - 1.58(W0 /u) for 1.0 < W 0 /u ~ 1.5 (8-4)

Gt= 0.30 - 0.06(W0 /u) for 1.5 < W 0 /u ~ 5.0 (8-5) 8.1.3 Average Wind Speed Using the joint frequency distribution, average wind speeds are obtained for each station. Values are obtained for each downwind direction (N, NNE, etc.) and for various release point classifications (stack, vent, and ground level).

8.1.3.1 Stack Release For a stack release, the following formula is used:

U5(9) = .I:{ f 5(n, 9,C)Un }/.I:{ f5(n, 9,c)} (8-6) where the summations are over wind speed classes n and stability classes c.

July 2018

CY-BR-170-301 Revision 10 Page 86 of 353 Average Wind Speed, Stack Release [m/sec]

The parameter fs is defined in Section B.1.2.2.

8.1.3.2 Ground Level Release For a ground level release, the following formula is used:

Ug(0) = I:{ fg(n, 0,c)Un }/ l°:{ fg(n, 0,C) } (8-7) where the summations are over wind speed classes n and stability classes c.

Average Wind Speed, Ground Level Release [m/sec]

I I:{ fv,elev(n,0,c) + fv,gnd(n,0,c)}

where the summations are over wind speed classes n and stability classes c.

Uv(0) Average Wind Speed, Vent [m/sec]

Release The average wind speed in downwind direction 0 for a vent release.

The parameters fv,elev and fv,gnd are defined in Section B.1.2.4.

8.2 GAUSSIAN PLUME MODELS As a plume of airborne effluents moves away from an elevated release point, the plume both broadens and meanders. It has been found that the time-averaged distribution of material in an effluent plume can be well represented mathematically by a Gaussian function.

July 2018

CY-8R-170-301 Revision 10 Page 87 of 353 8.2.1 Mathematical Representation In a widely used form of the Gaussian plume model, the distribution of radioactivity in a plume is represented mathematically by the equation below:

x,(x,y ,z) = [Q/(21t ay a zU )]exp(-y212a2y) x { exp[-(z-h e)2/2a2z] + exp[-(z+he)2/2a2z]} (8-9) x(x,y,z) Radioactivity Concentration The concentration of radioactivity at point (x,y,z). The x, y, and z axis are defined as follows:

x Downwind Distance [m]

Distance from the stack along an axis parallel to the wind direction.

y Crosswind Distance [m]

Distance from the plume centerline along an axis parallel to the crosswind direction.

z Vertical Distance [m]

Distance from the ground (grade level at the stack) along an axis parallel to the vertical direction.

Q Release Rate [µCi/sec]

Release rate of radioactivity.

Horizontal and Vertical Dispersion Coefficients [m]

Standard deviations of the Gaussian distributions describing the plume cross-sections in they and z directions, respectively. The values of ay and az depend on several parameters:

• Downwind distance x.

Because a plume broadens and meanders as it travels away from its release point, the values of ay and az increase as x increases.

• Atmospheric stability class.

The plume is broadest for extremely unstable atmospheric conditions (Class A) and narrowest for extremely stable conditions (Class G).

• Time period of averaging plume concentration.

The values of ay and crz increase as the averaging period increases.

u Average Wind Speed [m/sec]

The average wind speed. The average speed of travel of the plume in the x direction.

July 2018

CY-BR-170-301 Revision 10 Page 88 of 353 Effective Release Height [m]

The effective height of effluent release above grade elevation.

This may be greater than the actual release height (see Section 8.3.1.1.1 ).

The two exponential functions of z in the curly brackets of Equation 8-9 represent the emitted and reflected components of the plume. The reflected component (represented by the exponential with (z + he) in its argument) arises from the assumption that all material in a portion of the plume that touches ground is reflected upward. This assumption is conservative if one is calculating airborne radioactivity concentration.

8.2.2 Sector-Averaged Concentration Sometimes, it is desired to determine the average concentration of radioactivity in a sector due to release at a constant rate OVf?r an extended period of time (e.g., a year). For such a case, it is reasonable to assume that the wind blows with equal likelihood toward all directions within the sector. From Equation 8-9, the following equation for ground level radioactivity concentration can be derived:

Xsector =[2.032 f Q/(crz u x)]exp(-h2e/2cr2z) (8-10)

Xsector Sector-Averaged Ground Level [µCi/m3]

Concentration The time-averaged concentration of airborne radioactivity in a sector at ground level at a distance x from the release point.

2.032 A dimensionless constant.

f Sector Fraction The fraction of time that the wind blows into the sector.

Q Release rate of radioactivity. [µCi/sec]

The other parameter definitions are the same as for Equation 8-9.

8.3 RELATIVE CONCENTRATION FACTORx/Q The relative concentration factor xlQ (called "chi over Q") provides a simplified method of calculating the radioactivity concentration at a given point in an effluent plume when the release rate is known:

x =Q ( x/Q) (8-11) x Concentration of Radioactivity [µCi/m3]

Concentration of radioactivity at point (x,y ,z) in the atmosphere.

Q Release Rate [µCi/sec]

Release rate of radioactivity.

July 2018

CY-BR-170-301 Revision 10 Page 89 of 353 xJQ Relative Concentration Factor Relative concentration factor for point (x,y,z). The airborne radioactivity concentration at (x,y ,z) per unit release rate.

Expressions for x/Q based on Gaussian plume models can be obtained from the equations for concentration in x Section B.2 simply by dividing both sides of each equation by the release rate Q. For example, from Equation B-10, we obtain the following expression for the sector-averaged x/Q:

(XsectorlQ) = [2.032 f/(crz u x)]exp(-h2e/2cr2z) (B-12)

The values of xJQ used in ODCM calculations are both sector-averaged and time-averaged. The time averaging is based on the historical average atmospheric conditions of a specified multi-year time period (see Section 4.1.5) and is accomplished by use of the joint frequency distribution discussed in Section B.1.2. The formulas used to obtain the time- and sector-averaged x!Q are based on Equation B-12, but vary depending on whether the release is a stack, ground level, or vent release. The three cases are discussed below.

B.3.1 Stack Releasex For a stack release, the relative concentration factor is designated (x/Q)5 . Its value is obtained by the following formula:

(x/Q)5 = (2.032/R) l:{ f 5 (n,0,c) x [exp (-h2e/2cr2z)]/(un crz)} (8-13)

The summation is over wind speed classes n and atmospheric stability classes c.

(x/O)s Relative Concentration Factor, Stack Release The time- and sector-averaged relative concentration factor due to a stack release for a point at ground level at distance R in downwind direction 0.

2.032 Constant A dimensionless constant.

R Downwind Distance [m]

The downwind distance from the release point to the point of interest.

f 5 (n,0,c) Joint Frequency Distribution, Stack Release This function is defined in Section B.1.2.2.

Effective Release Height [m]

The effective height of an effluent release above grade elevation. For a stack release, he is obtained by correcting the actual height of the release point for plume rise, terrain effects, and downwash as described in Section B.3.1.1, below.

A wind speed representative of wind speed class n. For each wind speed class except the highest, Un is the average of the upper and lower limits of the wind speed range for the class. For the highest wind speed class, Un is the lower limit of the wind speed range for the class.

This expression is recommended by the NRC in Regulatory Guide 1.111 (Reference 7) and is based on a model designated there as the "constant mean wind direction model." In this model it is assumed that the mean wind speed, the mean wind direction, and the atmospheric stability class determined at the release point also apply at all points within the region in which airborne concentration is being evaluated.

8.3.1.1 Effective Release Height For a stack release, the effective height of an effluent plume is the height of the release point corrected for plume rise and terrain effects:

CY-BR-170-301 Revision 10 Page 91 of 353 B.3.1.1.1 Plume Rise Because nuclear power stations generally have plumes that are not significantly warmer than room temperature, plume rise due to buoyancy is neglected. The formulas used to calculate plume rise due to momentum are given below.

Stability Classes A, 8, C, and D For these stability classes (corresponding to unstable and neutral conditions), hpr is taken as the lesser of two quantities:

hpr = Minimum of [(hpr)1, (hpr)2] (B-16)

is calculated by the following equations:

Note that (hpr)1 can increase without limit as R increases; thus, the effect of (hpr)2 is to limit calculated plume rise at large distances from the nuclear power station.

8.3.4 Removal Mechanisms In Regulatory Guide 1.111, the NRC allows various removal mechanisms to be considered in evaluating the radiological impact of airborne effluents. These include radioactive decay, dry deposition, wet deposition, and deposition over water. For simplicity, these removal mechanisms cited by the NRC are not accounted for in the evaluation or use of x/Q in this manual. This represents a conservative approximation as ignoring removal mechanisms increases the value of x/Q.

8.3.5 Gamma-x/Q The noble gas dose factors of Reg. Guide 1.109, Table 8-1 are based upon assumption of immersion in a semi-infinite cloud. For ground level and mixed mode releases this tends to overestimate the gamma air dose arising from a plume that is actually finite in nature.

For elevated releases, the Reg. Guide 1.109 noble gas dose factors will underestimate exposure as they consider only immersion and not that portion of exposure arising from sky shine. At distances close in to the point of elevated release, the ground level concentration as predicted by x!Q will be essentially zero. In such a case, the sky shine component of the exposure becomes significant and must be considered.

The gamma- itQ provides a simplified method of calculating gamma air dose and dose rates for a finite and/or elevated plume. The methodology of Reg. Guide 1.109, Section C.2 and Appendix 8 provides the methodology for calculating finite cloud gamma air dose factors from which the gamma-x/Q values can be derived. Section 8.5 addresses the calculation of these dose factors.

The gamma-x/Q is defined such that for a given finite cloud the semi-infinite cloud methodology will yield the same gamma air dose as the finite cloud methodology.

Three gamma-x/Q values are defined: (x/Q) 5 Y, (x/Q)/ and (x/Q) 9Y for stack, vent and ground level releases, respectively. These gamma-x/Q values are calculated as follows:

The integrals involved in calculating I arise from conceptually dividing up the radioactive plume into small elements of radioactivity and adding up the doses produced at the point of interest by all of the small elements.

CY-8R-170-301 Revision 10 Page 103 of 353 SECTION 2 MODELS AND PARAMETERS FOR LIQUID EFFLUENT CALCULATIONS 8.14 INTRODUCTION Equations for radiation dose and radioactivity concentration due to liquid effluents are given in Section A.2 of Appendix A. The equations involve the following types of parameters:

• Flow and Dilution Parameters.

• Dose Factors.

• Measured Release Parameters.

• Transport/Consumption Parameters.

This section discusses the methodology used to determine these parameters. Section B.15 addresses dose calculations and Section B.16 addresses concentration calculations for tank discharges. For dose calculations, flow and dilution parameters are discussed for the River Model, which is used for all nuclear power stations.

8.15 DOSE 8.15.1 Drinking Water The radiation dose due to consumption of drinking water containing released radioactivity is calculated by Equations A-17, A-18 and A-19 of Appendix A:

D;!q = F At LLAaipJC 1 (A-17) p I Waste Flow F=------ (A-18)

Dilution Flow x Z (A-19)

The summation is over index i (radionuclides) and p (pathways). The parameters are defined in Section A.2.1 of Appendix A.

This methodology addresses the following considerations:

• The duration of the release, flt.

• The concentration of the activity released, C1*

• The dilution that takes place in the environment is represented by the parameters F and Z.

• Receptor consumption rate, U0 w.

• Dilution which occurs from the near field discharge area to potable water intake as represented by ow .

• The dose commitment per unit of ingested radioactivity is DFLaiJ*

July 2018

CY-BR-170-301 Revision 10 Page 104 of 353 8.15.2 Aquatic Foods (Fish)

Near the nuclear power stations, the only aquatic food of significance for human consumption is fish. The liquid dose due to consumption of fish containing released radioactivity is calculated by Equations A-17, A-18 and A-20 of Appendix A.

(A-20)

The parameters are defined in Section A.2.1 of Appendix A.

This is similar to the methodology used for calculating the dose due to drinking water except for the addition of the bioaccumulation factor, 8Fi. This factor is the equilibrium ratio of the concentration of radionuclide i in fish (pCi/kg) to its concentration in water (pCi/L). It accounts for the fact that radioactivity ingested by fish can accumulate in theirI bodies to a higher concentration than in the waters in which the fish live.

8.15.3 Parameters 8.15.3.1 Flow and Dilution The values of dilution can differ for potable water and fish. The dilution for potable water will depends on where water is drawn, while that for fish will depends on where the fish are caught. Models used to determine these parameters are discussed below. The values used for each station are summarized in Table F-1 of Appendix F.

8.15.3.1.1 River Model For the purpose of calculating the drinking water dose from liquid effluents discharged into a river, it is assumed that total dilution of the discharge in the river flow occurs prior to consumption. The measure of dilution for the

=

potable water pathway is described by the parameter ow. A value of ow 1 represents no dilution.

For the fish consumption pathway, the dilution in the near-field is described by the parameter Z. This is an estimate of the dilution of released radioactivity in the water consumed by fish caught near the station downstream of its discharge. No additional dilution is assumed to occur.

8.15.3.2 Dose Factors Equations A-17 through A-20 of Appendix A determine dose due to ingested radioactivity using the same ingestion dose factor DFLija as used in the evaluation of airborne radioactivity which is ingested with foods. The units of DFLija are:

(mrem) per (pCi ingested)

For 10CFR50 Appendix I compliance, the data of Tables E-1, E-12, E-13 and E-14 of Reg. Guide 1.109, are used for four age groups and for seven organs, with the whole body considered as an organ.

8.15.3.3 Measured Releases Calculations of dose due to liquid effluents require measured values of n:idioactivity concentration release (Ci) for input. These release values are obtained per the nuclear power station procedures.

July 2018

CY-BR-170-301 Revision 10 Page 105 of 353 B.15.3.4 Consumption Equations A-19 and A-20 of Appendix A involve consumption rates for water and fish (Uaw and U/). The values used are specified for each nuclear power station in Table F-1 of Appendix F.

8.16 CONCENTRATION IN TANK DISCHARGES The concentration of radioactivity in a release to the unrestricted area due to a tank discharge is calculated by Equation A-22 of Appendix A:

C =ct Waste Flow (A-22) 1 1 Dilution Flow The parameters are defined in Section A.2.3 of Appendix A.

The radioactivity concentration released from the tank (ct1 at flow rate Fr) is diluted by mixing with the initial dilution stream (with flow rate Fd) to yield a lower concentration (C 1 ) in the combined streams.

CY-BR-170-301 Revision 10 Page 119 of 353 Footnotes:

There are numerous Ft and FM values that were not found in published literature. In these cases, the periodic table was used in conjunction with published values. The periodic table was used based on a general assumption that elements have similar characteristics when in the same column of the periodic table. The values of elements in the same column of the periodic table, excluding atomic numbers 58-71 and 90-103, were averaged then assigned to elements missing values located in the same column of the periodic table. This method was used for all columns where there were missing values except column 3A, where there was no data, hence, the average of column 2B and 4A were used.

1. Values obtained by averaging Reference 6 values of Ca, Sr, Ba and Ra.

2. Ft value obtained by assigning the Reference 6 value for I. FM value obtained by averaging l(Ref. 6) and Br (Ref.16).

3. Ft values obtained by averaging Zn (Ref.6) and Pb (Ref. 98); there were no values for elements in the i same column; an average is taken between values of columns 2B and 4A on the periodic table. FM values obtained by using the value for Tl from Reference 16.

4. Values obtained by averaging Reference 6 values of Y and La.

5. Values obtained by assigning the Reference 6 value for Zr.

6. Ft values obtained from Ref. 6 value for Nb. FM values obtained by averaging values for Nb (Ref.6) and Ta (Ref. 16).

7. Values obtained from the Reference 6 values for Pb.

8. Values obtained from the Reference 6 values for Bi.

9. Values obtained from the Reference 6 values for Te.

10. Values obtained from the Reference 6 values for Ni.

11. Ft values obtained from Ref. 6 values for Zn. FM values obtained by averaging the Reference 6 values for Zn and Hg.

12. Values obtained by averaging Reference 6 values for Mn, Tc, Nd and Reference 98 value for U.

13. Values obtained by averaging Reference 6 values from Fe and Ru.

14. Values obtained by averaging Reference 6 values from Co and Rh.

15. Values obtained by averaging Reference 6 values from Cu and Ag.

NA= It is assumed that noble gases are not accumulated.

In Reference 6, see Table A-1.

A number of bioaccumulation factors could not be found in literature. In this case, the periodic table was used in conjunction with published element values. This method was used for periodic table columns except where there were no values for column 3A so the average of columns 2B and 4A was assigned.

CY-BR-170-301 Revision 10 Page 136 of 353 ODCM BASES and REFERENCE (Generic Section)

This document provides supplementary information on the bases of material in the generic section of the ODCM, Chapters 1 through 6 and Appendices A through C.

0.1 BASES OF CHAPTER 1, INTRODUCTION 0.1.1 Offsite Radiation Doses Due to Nuclear Power Plants 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, (Reference 80). The table includes the following data:

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." Evidence of this is provided by the following data:

• Calculated Doses Due to Airborne Effluents The maximum calculated doses due to airborne effluents from Dresden 3 for 1987 were as follows (Reference 58, Page 73):

Gamma Air (mrad) 0.19 Beta Air (mrad) 0.06 Total Body (mrem) 0.19 Skin (mrem) 0.14 Thyroid (mrem) 1.62

• Dosimeter Measurements of Direct Radiation Dosimeter measurements of background radiation at 17 locations in the vicinity of the Dresden Station are reported on Page 86 of Reference 55. At these locations, background radiation ranged from 12 mR/quarter to 21 mR/quarter in 1987. The standard deviations of the measurements ranged from 0.6 mR/quarter to 4. 7 mR/quarter. Fluctuations from quarter to quarter at a given location and fluctuations between measuring locations were often larger than 1 mR/quarter. Note that the standard deviations and the fluctuations both exceeded the calculated maximum offsite total body dose of 0.19 mrem.

The text of Chapter 1 also states that "assessing compliance with regulatory limits requires calculations because some of the limits involve quantities that cannot be directly measured ... " Limits that cannot be feasibly monitored by direct measurement include doses to internal organs and doses attributable to particular pathways (see Appendix A).

July 2018

CY-BR-170-301 Revision 10 Page 137 of 353 0.1.2 Historical and Concurrent Meteorology The use of historical average atmospheric conditions for assessment of radiation doses due to airborne effluents is stipulated in the Bases Section 12.4 and 12.6 of each station's RETS.

For Byron and Braidwood, there is an additional requirement that the Annual Radiological Environmental Operating Report include an assessment of radiation doses due to gaseous effluents based on the "meteorological conditions concurrent with the time of release. The bases for this requirement are from Reference 7.

0.2 BASES OF CHAPTER 2, REGULATIONS AND GUIDELINES See the documents cited in the text.

0.3 BASES OF CHAPTER 3, PATHWAYS General information on offsite exposure pathways may be found in several texts and monographs (see References 16, 18, 20, 22, 25, 28, 29 and 31 ).

0.3.1 Airborne Releases (Section 3.1)

The nuclear power stations address radiation dose for the airborne pathways considered in NUREG 0133 (Reference 14). The airborne pathways found in NUREG 0133 are:

• Exposure to a cloud of noble gas.

• Exposure to standing on a contaminated ground plane.

• Inhalation of radioiodines, tritium and/or particulates.

• Ingestion of contaminated vegetation.

• Ingestion of contaminated cow and/or goat milk.

• Ingestion of contaminated cow meat.

The noble gas exposures are assessed at the site boundary. The ground plane, inhalation and ingestion exposures are determined at the location in the unrestricted area where the combination of pathways, age group and airborne deposition produce the highest potential dose to a member of the public. The ground plane and inhalation pathways are considered present at every location in the unrestricted area. Ingestion pathways are considered present at the locations determined by the land use census.

Soil uptake is not considered by the NU REG 0133 methodology but is addressed by Regulatory Guide 1.109 (Reference 6). Ingestion exposure through the mechanism of soil uptake has been shown to be minor as compared to direct deposition onto foliage. This assumption is based upon an analysis of three nuclides: 1-131, Cs-134 and Cs-137. In a study of nuclear power station radiation exposures in the upper Mississippi River basin, these nuclides were found to contribute the major portion of the dose due to exposure to airborne radioactivity deposited on soil (see page IX-12 of Reference 20).

The relative importance of uptake from soil was assessed by use of Equation C-5 of Regulatory Guide 1.109.

This equation calculates radioactivity concentration in vegetation. The first term inside the curly brackets of the equation represents the contribution from radioactivity directly deposited on plant foliage. The second term represents the contribution from radioactivity initially deposited on the ground and then taken up through the root system of the vegetation. For each of the three nuclides, the ratio of the uptake term to the direct deposition term was evaluated for two pathways; the grass-cow-milk pathway and the pathway of direct ingestion by man of produce and leafy vegetables. The parameter values used and the results are in Table 0-1 of this document. For the six cases, the soil uptake term ranged from about 0.01 % to about 10% of the direct deposition term (see the column labeled "Uptake+ Direct Dep" in Table 0-1).

July 2018

CY-BR-170-301 Revision 10 Page 138 of 353 0.3.2 Liquid Releases (Section 3.2)

The nuclear power stations address radiation dose for the waterborne pathways considered in NU REG 0133.

The waterborne pathways found in NUREG 0133 are:

• Ingestion of contaminated potable water.

• Ingestion of fish taken from contaminated water.

• Ingestion of invertebrates taken from contaminated water.

All of these dose pathways are considered unless demonstrated not be present. Exposure can also occur through recreation (shoreline activities, swimming and boating) and irrigation pathways (irrigation of directly ingested vegetation and food crops for animal consumption), but these have been shown to be minor as compared to direct ingestion.

The liquid pathways were evaluated based on surveys of surface water use and on liquid pathway dose calculations. Table 0-2 of this document summarizes principal results of the surface water use surveys. On the basis of these surveys, it was decided to ignore the following pathways:

• Ingestion of vegetation contaminated because of irrigation with water containing radioactivity from plant liquid discharges.

• Ingestion of radioactivity that entered an animal food product (milk or meat) because the animal drank water contaminated by radioactive liquid effluents from the plant or because the animal consumed feed contaminated by irrigation with such water.

Calculations were performed to estimate annual doses from the following liquid pathways:

• Consumption of drinking water.

• Consumption of fish.

• Shoreline activities (with exposure to shoreline sediments).

• Swimming and boating.

Predicted annual doses to the total body and the thyroid for the six nuclear power stations are summarized in Tables 0-3 and 0-4 of this document. In all but one of the cases tabulated, the liquid pathway with the maximum annual dose is fish ingestion; the exception is for thyroid dose at Dresden 2/3, for which the maximum liquid pathway is consumption of drinking water. Doses due to shoreline activities and swimming and boating are not evaluated annually because dose estimates for these pathways are generally low. In Tables 0-3 and 0-4, they range from 0.02% to 10% of the doses calculated for the maximum pathway.

0.3.3 Radiation from Contained Sources (Section 3.3)

Annual radiation doses due to contained sources of radioactivity at nuclear power stations are judged to be negligible in comparison with applicable limits except for doses due to BWR turbine skyshine. This judgment is based on the considerations below.

Evaluations in the Environmental Reports Evaluations of direct radiation from the nuclear power stations are reported in Section 5.2.4.3 of the Environmental Reports for the Braidwood, Byron, and LaSalle Stations. For the two PWRs (Braidwood and Byron), the radiation sources considered were the following:

The containment building.

Nitrogen-16 in primary coolant.

Radioactivity in tanks storing refueling water, primary water or contaminated secondary water.

July 2018

CY-BR-170-301 Revision 10 Page 139 of 353 Annual doses calculated on the basis of 100% occupancy were as follows:

Distance From Sources Annual Dose (miles) (mrem/yr)*

0.3 1.5EO 0.6 4.4E-2 1.0 1.4E-3 These results may be compared with the distances to the closest points on the site boundaries, which are as follows:

Distance to Closest Point On Boundary Station (miles)**

Braidwood 0.32 Byron 0.50 From these data, the maximum annual dose at the site boundary due to direct radiation from PWRs is on the order of 1.5 mrem/yr assuming 100% occupancy at the boundary. Since the actual occupancy is likely to be much lower than 100%, the actual annual dose is likely to be much lower than 1.5 mrem/yr. Therefore, the direct radiation dose from contained sources at PWRs is judged to be negligible in comparison with 40CFR 190 annual limits (25 mrem to the total body, 75 mrem to the thyroid, and 25 mrem to other organs).

For LaSalle, the maximum annual dose at the site boundary due to direct radiation was calculated in the Environmental Report to be less than 4 mrem. The largest contributor was found to be nitrogen-16 from process steam. The cycled condensate storage tanks were considered in the calculation and found to contribute less than 0.1 mrem/yr. Based on these results, the direct radiation dose from contained sources at BWRs is judged to be negligible in comparison with 40CFR190 limits except possibly for the dose due to nitrogen-16.

• Per Table 5.2-9 of Byron and Braidwood Environmental Reports.

• • Based on data in ODCM Table F-3 of Appendix F.

Interim Radwaste Storage Facilities Interim Radwaste Storage facilities (IRSF) were designed to serve as temporary repositories of solidified (dewatered) radwaste before shipment offsite. The surface dose rate of these containers may be as high as 15 R/hr (or 380 R/hr if 50.59 evaluation has been approved).

Consideration is also being given to store containers of compacted dry active waste (DAW) in Sea-Land containers at all nuclear power plant sites. These may have surface dose rates as high as 8 mR/hr at a distance of 2-meters from the container surface.

Both the IRSF and DAW will contribute direct radiation to locations in the controlled and unrestricted areas. Thus a dose assessment is required to assure site compliance to the regulations of 40CFR190 and 10CFR20.

The doses due to IRSF's have been calculated in References 60, 61, 62 and 63. In these calculations, the containers were assumed to have a contact dose rate of 15 R/hr; consideration was given to accessible sites outside of the restricted area boundary, but near the IRSF. Although some of these sites are less than 200 meters from the IRSF, the annual doses are less than 10% of the 40CFR190 limit of 25 mrem/year when realistic occupancy factors are considered. (Additional calculations may be performed using other assumptions.)

The above calculations are, of course, estimates as the inventories, nuclide mixes, decay times, container self-shielding, and other factors affect the corresponding out-of-building dose rate. As the IRSF's become operational, the above estimates will be re-evaluated. "A correlation of internal IRSF dose rate (radiation levels) with measured external IRSF dose ratewill be evaluated as a better means of quantifying the IRSF offsite dose rates.

July 2018

CY-BR-170-301 Revision 10 Page 140 of 353 The dose due to storage of Dry Active Waste (DAW) on site in arrays of Sea/Land Vans has been evaluated. For a design basis source of 8 mR/hr at a distance of 2 meters, calculations (References 65, 66, 67 and 68) show that a dose rate of 1 mrem per year will not be exceeded at the restricted area boundary for realistic combinations of DAW locations and occupancy factors.

Since occupancy at the points of maximum offsite exposure is likely to be much less than 100%, doses due to the interim radwaste storage facilities are judged negligible in comparison with 40CFR190 limits.

Independent Spent Fuel Storage Installation (ISFSI) 10CFR72.104 dose limits are the same as those specified by 40CFR190. ISFSI dose contribution is in the form of direct radiation as no liquid or gas releases are expected to occur. The 10CFR72.212 report prepared in accordance with ISFSI requirements assumes a certain array of casks exists on the pad. The dose contribution from this array of casks, in combination with historical uranium fuel cycle operations prior to ISFSI operations, was analyzed to be within the 40CFR190 and 10CFR72.104 limits. A fully loaded ISFSI is not expected to exceed 10CFR72.104 limits at the current nearest resident. However, Initial Dose vs. Distance calculations identified an area of approximately 200 meters beyond the Owner Controlled Area boundary that could exceed limits if a member of the public permanently relocates in this zone. It is understood that the dose calculations are based on worst case scenarios and that empirical radiation dose data from strategically placed dosimeter sets will be utilized to accurately measure true radiation dose at the Owner Controlled Area boundary and the nearest resident. The nearest real individual to the ISFSI was determined to be different than the nearest real individual to the plant. Therefore, the Land Use Census will be the control provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the monitoring program are made if required by the results of the census.

If the dose limits of 40CFR190 or 10CFR72.104 are exceeded, a special report to the NRC as well as an appropriate request for exemption/variance is required to be submitted to the NRC. The requirement that the dose limits of 10CFR72.104 apply to "any real individual" is controlled for ISFSI activities in the ISFSI 72.212 report.

0.4 BASES OF CHAPTER 4, INTRODUCTION TO METHODOLOGY Most of the material in this chapter is based on Appendix A. Additional information on bases is provided below.

0.4.1 Introduction of Time Factors The release rate of radioactive materials is the discharge of radioactive materials in liquid or gaseous effluents per unit time. The second is used as the practical reporting time unit for establishing release rates to show compliance with instantaneous limitations for noble gases. The hour is used as the practical reporting time unit is established average release rates to show conformance with the requirements of 10CFR50 for radioiodines and particulates released in gaseous effluents and for liquids effluents.

The energies and intensities of radiations emitted from them are listed in standard compendia (e.g., see Reference 70). From Reference 70, Krypton-89 has gamma and beta emissions in excess of 4 MeV and Xenon-137 has beta emissions in excess of 4 MeV.

CY-BR-170-301 Revision 10 Page 141 of 353 Gamma Radiation Mean Free Path The mean free path X of gamma radiation is calculated using the following equations:

x = 1/µ (0-1)

The results for photon mean free path (Section 4.2.1) are based on data in Reference 71. For a 4-MeV photon, the calculation is as follows:

CY-BR-170-301 Revision 10 Page 142 of 353 Range of Beta Radiation in Air The results for beta radiation range (Section 4.2.2) are based on equations in Reference 38. The range of beta radiation with a maximum energy greater than 2.5 MeV is given by the following equation (Reference 38, Page 100):

R = (530) (Emax) - 106 (0-3) 2 R Range [mg/cm ]

Maximum Beta Energy [MeV]

For Emax =4 MeV, 2

R = (530)(4) - 106 = 2.01 E3 mg/cm For an air density of 1.293 mg/cc, the range is 2

R =(412 )(Emax)1.265 * (0.0954)(1n Emax) (0-4) where R and Emax have the same definitions as for Equation 0-3.

For example, for Emax =0.1 MeV, R =(412 ) (0. 1)1.2ss.10.0954)1n(o.11 =13.5 mg/cm2 For an air density of 1.293 mg/cc, the range is 2

[(13.5 mg/cm )/(1.293 mg/cc)] (1 ft/30.48 cm)= 0.34 ft 0.4.4 Radionuclide Types Considered For Airborne Effluent Exposure Pathways (Table 4-1)

The radionuclide types considered are the same as those recommended for concern in Regulatory Guide 1.109 except that carbon-14 is omitted. The reasons for this are discussed in the next section.

July 2018

CY-BR-170-301 Revision 10 Page 143 of 353 0.4.5 Reasons for Not Calculating Doses Due to Carbon-14 Carbon-14 is not considered by the stations because their RETS do not require it. The stations are required to consider only the following non-noble gas radionuclides: iodine-131, iodine-133, tritium, and all radionuclides in particulate form with half-lives greater than 8 days. Although carbon-14 has a half-life of 5730 years, it does not fall in the last category (in particulate form with half-life greater than 8 days) because it is emitted as a gas, mainly C0 2 (see Reference 29, Page 167). Moreover, carbon-14 was not found to be a significant contributor to offsite radiation dose in a study of the potential radiological implications of nuclear facilities in the upper Mississippi River basin (see Reference 20, Page IX-8, Table IX-2).

0.7 BASES OF AIRBORNE EFFLUENT CALCULATIONS (SECTION A.1 AND APPENDIX B)

The methodology used to calculate doses and dose rates due to releases of radioactivity in airborne effluents is discussed below. The calculations use equations presented in Section A.1 of Appendix A. The equations involve meteorological transport and dose factors that are either obtained from the literature or calculated as described in Appendix 8.

For the most part, the methodology of this manual for airborne effluent dose calculations is identical to that of Regulatory Guides 1.109 (Reference 6) and 1.111 (Reference 7). In the discussion below, special attention will be given to the few differences.

0.7.1 Release Point Classifications (Section A.1.1 of Appendix A)

Regulatory Guide 1.109 uses two classifications for airborne releases (see Reference 6, Regulatory Position C.2):

• Releases from free standing stacks more than 80 meters high.

• All other releases.

This manual uses three classifications for airborne releases: stack, ground and vent level. The classifications used here are based on Regulatory Positions C.2.a and C.2.b of Regulatory Guide 1.111.

0.7.2 Meteorological Data (Section B.1.1 of Appendix B)

The information in Section 8.1.1 of Appendix 8 is based on Sargent & Lundy reviews and analyses of meteorological data from the nuclear stations. The procedure for treating calms is based on guidance in Regulatory Guide 1.111, Regulatory Position C.4.

0.7.3 Joint Frequency Distribution (Section B.1.2 of Appendix B)

The information in Section 8.1.2 of Appendix 8 is based on discussions with Sargent & Lundy. The procedure for determining the JFD for a vent release is based on Regulatory Position C.2.b of Regulatory Guide 1.111. For each nuclear power station, an historical average JFD was calculated at Sargent & Lundy by a computer program that later evolved into the computer program METWRSUM (Reference 75). For further information on these calculations, see Reference 76.

July 2018

CY-BR-170-301 Revision 10 Page 144 of 353 Wind speed and direction may change with height. In accordance with Regulatory Position C.2.b of Regulatory Guide 1.111, JFD calculations for elevated releases were made using wind parameters representative of conditions at the actual release height, and calculations for ground level releases were made using wind parameters corresponding to a height of approximately 10 meters. As noted in Reference 76, in some cases interpolation of wind speed data measured at different heights was used to obtain data characteristic of the height of interest.

0.7.4 Average Wind Speed (Section 8.1.3 of Appendix 8)

The equations for obtaining average wind speed are based on the standard method of determining the average value of a quantity for which the frequency distribution is known. Average wind speeds for the nuclear power stations were computed using Sargent & Lundy computer program AZAP (Reference 77).

Regulatory Position C.2.a of Regulatory Guide 1.109 and C.1.c of Regulatory Guide 1.111 specify that a wind speed class be represented by the wind speed of its midpoint (i.e., average of its upper and lower limits). In the 1

calculations this is done for each wind speed class except the highest. The highest class contains all wind speeds greater than a specified value and so has an undefined upper limit. This class is represented by the lower limit of its wind speed range in all calculations for this manual (calculations of average wind speed, xlQ, gamma dose factors, and total body dose factors).

0.7.5 Gaussian Plume Models (Section 8.2 of Appendix 8)

For discussion of the Gaussian plume diffusion model and its applications to dose assessment, see References 18 (Sections 2-7.2, 3-3, 4-6.2, 7-4, and 7-5), 24, 31 (Section 2.1), and 22 (Chapter 3).

Equation B-9 of Appendix B is identical to Equation 3.115 on Page 99 of Reference 18.

Equation B-10 of Appendix Bis derived from Equation B-9 of Appendix Bas follows:

A location at ground level (z =0) is assumed. Equation B-9 of Appendix B becomes:

(0-5)

This expression for x(x,y,O) is integrated in the crosswind direction from y = -oo to +oo. This yields the following result (see Equation 3.143 of Reference 18):

[21/2Q/(1t1/20'zU )]exp(-h2e2/2cr2z)

The above expression is divided by the width of a sector at downwind distance x, 2nx/16.

The result is:

that is equal to 2 2

[2.032Q/(O'z u x)]exp(-h 0 /2cr z)

The result above is multiplied by a fraction f representing the fraction of time that the wind blows into the sector of interest. This yields that is identical to the expression in Equation B-10 of Appendix Band also to Equation 3.144 of Reference 18.

CY-8R-170-301 Revision 10 Page 145 of 353 0.7.6 Relative Concentration Factor xJQ (Section 8.3 of Appendix 8) 0.7.6.1 Stack Release Equation B-13 of Appendix Bis the formula for calculating the relative concentration factor (x/O)s due to a stack release. Equation B-13 of Appendix B is obtained from the formula for sector-averaged concentration, Equation B-10 of Appendix B, and is of the same form as Equation 3 of Regulatory Guide 1.111. In applying Equation B-13 of Appendix B, the vertical plume spread is calculated in the way specified in the regulatory guide.

The effective release height is calculated with Equation B-14 of Appendix B. The formulas used are in accordance with those in Regulatory Guide 1.111. However, the following should be noted:

• Plume heights are limited to a maximum of 100 meters. This is done to allow use of the plume depletion and relative deposition data in Regulatory Guide 1.111. These data are not provided for release heights above 100 meters. The limitation to 100 meters represents a conservative approximation for cases in which the release height and the plume rise formulas would lead to higher plumes.

• Due to the general flatness of the terrain in the vicinity of nuclear power stations, all terrain correction parameters were taken as zero.

• Plume rise due to buoyancy was ignored because typical nuclear power plant plumes are not significantly warmer than room temperature. This neglect of buoyancy (which can be significant for plumes from fossil plants) is in accord with the guidelines of Regulatory Guide 1.111. The regulatory guide states that plume rise is calculated in accordance with Reference 78, which neglects rise due to buoyancy (see last sentence on Page 5 of Reference 78).

July 2018

CY-BR-170-301 Revision 10 Page 146 of 353 0.7.6.2 Ground Level Release Equation B-25 of Appendix B is the formula for calculating the relative concentration factor (x/0) 9 due to a ground level release. Equation B-25 of Appendix B is obtained from the formula for sector-averaged concentration, Equation B-10 of Appendix B, and is of the same form as Equation 3 of Regulatory Guide 1.111. In applying Equation B-25 of Appendix B, the vertical dispersion coefficient is calculated using Equations B-26, B-27 and B-28 of Appendix B, which are based on the prescription in Regulatory Position C.2.c.

0.7.6.3 Vent Release Equation B-29 of Appendix B may be used for calculating the relative concentration factor (x/O)v due to a vent release. The relative concentration factor is obtained as a mixture of stack and ground level factors in accordance with the guidelines in Regulatory Position C.2.b of Regulatory Guide 1.111.

0.7.6.4 Removal Mechanisms '

Regulatory Position C.3 of Regulatory Guide 1.111 discusses three removal mechanisms that reduce airborne radioactivity concentration: radioactive decay, dry deposition and wet deposition. In the dose calculations involving x/Q (see Appendix A), radioactive decay is taken into account by adjusting the measured release rate of each radionuclide for radio decay in transit from the release point to the dose point. However, wet and dry deposition are not considered. This is a conservative approximation made to simplify the calculations. If these deposition mechanisms were considered, the x!Q values for noble gases would be different from those for particulate and iodine.

0.7.6.5 Gamma-x/Q (Section B.3.5)

The noble gas dose factors used in Equations A-1, A-3, A-4, A-5 of Appendix A are taken from Regulatory Guide 1.109, Table B-1. These values are based upon assumption of immersion in a semi-infinite cloud. For ground level and mixed mode releases this tends to overestimate the gamma air dose arising from a plume that is actually finite in nature.

For elevated releases, the Regulatory Guide 1.109 noble gas dose factors will underestimate exposure as they consider only immersion and not that portion of exposure arising from sky shine. At distances close in to the point of elevated release, the ground level concentration as predicted by xtQ will be essentially zero. In such a case, the sky shine component of the exposure becomes significant and must be considered.

The gamma-x/Q provides a simplified method of calculating gamma air dose and dose rates for a finite and/or elevated plume. Regulatory Guide 1.109, Section C.2 and Appendix B provides the methodology for calculating finite cloud gamma air dose factors from which the gamma-x/Q values can be derived.

The gamma-x/Q is defined such that for a given finite cloud the semi-infinite cloud methodology will yield the same gamma air dose as the finite cloud methodology.

Three gamma-x/Q values are defined: for stack, vent and ground level releases, respectively. The gamma-x/Q values are calculated by Equations B-30, 8-31 and B-32 of Appendix B and makes use of the finite cloud gamma air dose factors described in Section B-5 of Appendix B. These equations also utilizes a noble gas nuclide fraction. These fractions can be based upon historical data or a calculated noble gas source term.

July 2018

CY-8R-170-301 Revision 10 Page 147 of 353 0.7.7 Relative Deposition Factor D/Q (Section 8.4 of Appendix 8)

Equations B-34, B-35, and B-36 of Appendix B are used to calculate values of the relative deposition factor D/Q

[1/m 2]. These equations use data on deposition rate D, [1/m] provided in Figures 6 through 9 of Regulatory Guide 1.111. Values of D/Q are obtained from D, in accordance with the prescription in paragraph 5 of Regulatory Position C.3.b. Equation B-37 of Appendix B applies to a vent release and provides a value that is a mixture of stack and ground level factors in accordance with the guidelines in Regulatory Position C.2.b of Regulatory Guide 1.111.

0.7.8 Gamma Air Dose (Section A.1.2.1 of Appendix A and Section 8.5 of Appendix 8) 0.7.8.1 Dose (Equation A-1 of Appendix A)

Gamma air dose is calculated by Equation A-1 of Appendix A. This equation makes use of a term referred to as gamma-x/O (gamma-chi-over-q) which is explained in Section 4.2.1.1. It is derived from the methodology of NUREG 0133, Section 5.3.1.

NUREG 0133 deals only with two classes of noble gas releases; those from free-standing stacks more than 80 meters high and all other noble gas releases. Equation A-1 of Appendix A contains terms representing the appropriate release point classifications discussed in Section 4.1.4. The use of three release point classifications is based on Regulatory Guide 1.111, Regulatory Position C.2. The dose factors Mi used in Equation A-1 of Appendix A are identical to the gamma air dose factors DF8i specified in Table B-1 of Regulatory Guide 1.109.

0.7.8.2 Dose Factors (Section 8.5 of Appendix 8)

Calculation of gamma-x/Q involves the use of finite plume gamma air dose factors, each of which represents dose rate at a specified point per unit of radioactivity release rate. The dose factors are calculated by Equations B-40 through B-42 of Appendix B.

Equation B-40 of Appendix B is used to calculate the finite plume gamma air dose factors for a stack release.

The formula is based on Equations 6 and B-1 of Regulatory Guide 1.109. Except for notation, Equation B-40 of Appendix B and the regulatory prescription are identical.

The finite plume gamma air dose factors for a ground level release are obtained by Equation B-40 of Appendix B using the ground level joint frequency distribution data and assuming an effective release height of zero. The use of a finite plume model differs from NUREG 0133 in that ground level releases are based on a semi-infinite cloud model (see Equation 7 of Regulatory Position C.2.b). The approach used here is more realistic than that in the regulatory guide.

Equation B-42 of Appendix 8 is used to calculate the gamma air dose factors for a vent release. The dose factors are obtained as a mixture of stack and ground level dose factors in accordance with the guidelines in Regulatory Position C.2.b of Regulatory Guide 1.111.

July 2018

CY-BR-170-301 Revision 10 Page 148 of 353 0.7.8.3 Use of Unrestricted Area Boundary Values for Gamma Air Dose Factors To assess compliance with RETS limits on gamma air dose, maximum offsite values of gamma air dose should be determined. Therefore, the gamma-x/Q values should be determined for the offsite locations where they are maximum. However, the values provided in Table F-5b of Appendix F are for the unrestricted area boundary.

They are judged to be very good approximations to the maximum offsite values. This judgment is based on published values for finite cloud gamma air dose factors used to calculate gamma-x/Q (see Reference 79).

Reference 79 provides values of the gamma air factor as follows:

• For 13 of the 15 noble gas radionuclides included in the ODCM.

• For each of the seven atmospheric stability classes considered in this manual (A through G).

• For two release heights (0 and 100 meters).

• As a function of distance from the release point. (Data is provided for six downwind distances over the range from 400 to 16,090 meters.)

Examination of the dose factor in Reference 79 for the sector-averaged meandering plume model reveals the following:

• For a ground level release, the dose factor always decreases as distance from the release point increases. (The plume broadens as it moves away from the release point.)

• For an elevated release, the dose factor decreases as distance from the release point increases with only a few exceptions (five exceptions among the 546 dose factors that are provided). The exceptions involve only weak gamma emitters (Xe-131m, Xe-133m, and Xe-133) in combination with certain stability classes.

(The exceptions are due to portions of an elevated plume moving closer to the ground as the plume moves away from the release point. This increases dose rate at ground level.)

The gamma air dose factors used to calculate gamma-x/Q in each station's Appendix F are based on historical average atmospheric conditions (see Section 4.1.5). Therefore, each gamma air dose factor involves an average over all of the meteorological stability classes, nearly all of which have dose factors that decrease as distance from the release point increases. Furthermore, the gamma air dose factors in the ODCM for ground level releases or for mixed mode releases include a large ground level component. The ground level dose factors will always decrease as distance increases, and the mixed mode factors are likely to decrease with distance because of the effect of their ground level component. Thus, it is judged that a gamma-x/Q value calculated at the unrestricted area boundary in each sector is a very good approximation to the highest offsite value for that sector.

0.7.9 Beta Air Dose (Section A.1.2.2 of Appendix A and Section B.7 of Appendix B)

Beta air dose is calculated by Equation A-2 of Appendix A. This equation is explained in Section 4.2.2. It is based on Section 5.3.1 of NUREG 0133. Like Equation A-1 of Appendix A for gamma air dose, Equation A-2 of Appendix A contains a term representing each of the three release point classifications discussed in Section 4.1.4. The use of three release point classifications is based on Regulatory Guide 1.111, Regulatory Position C.2.

The dose factors Ni used in Equation A-2 of Appendix A are identical to the beta air dose factors DFBi specified in Table 8-1 of Regulatory Guide 1.109.

July 2018

CY-BR-170-301 Revision 10 Page 149 of 353 0.7.10 Total Body Dose (Section A.1.2.3 of Appendix A and Section 8.6 of Appendix 8)

Total body dose is calculated by Equation A-3 of Appendix A. This equation is explained in Section 4.2.3. It is based on Section 5.3.1 of NUREG 0133. Like Equation A-1 of Appendix A for gamma air dose, Equation A-3 of Appendix A contains a term representing each of the three release point classifications discussed in Section 4.1.4. The use of three release point classifications is based on Regulatory Guide 1.111, Regulatory Position C.2.

The dose factors Ki used in Equation A-3 of Appendix A are identical to the beta air dose factors DFBi specified in Table 8-1 of Regulatory Guide 1.109.

0.7.11 Skin Dose (Section A.1.2.4 of Appendix A and Section 8.7 of Appendix B)

Skin dose is calculated by Equation A-4 of Appendix A. This equation is explained in Section 4.2.4. It is based on Section 5.2.1 of NUREG 0133. Like Equation A-1 of Appendix A for gamma air dose, Equation A-4 of Appendix A contains a term representing each of the three release point classifications discussed in Section 4.1.4. The use of three release point classifications is based on Regulatory Guide 1.111, Regulatory Position C.2.

The dose factors Li and M used in Equation A-4 of Appendix A are identical to the gamma and beta skin dose factors DFSi specified in Table 8-1 of Regulatory Guide 1.109.

The gamma contribution to skin dose is calculated with gamma-D/Q in the same manner as that of Equation A-1 of Appendix A to calculate gamma air dose. This approach differs from that of the regulatory guide in that a finite cloud model is used in accounting for the portion of the dose contribution to the skin due to gamma emissions.

This is more realistic than the semi-infinite cloud model used in the regulatory guide.

0.7.12 Total Body Dose Rate (Section A.1.3.1 of Appendix A)

Total body dose rate is calculated by Equation A-5 of Appendix A. This equation is explained in Section 4.2.3.

0.7.13 Skin Dose Rate (Section A.1.3.2 of Appendix A)

Skin dose rate is calculated by Equation A-6 of Appendix A. This equation is explained in Section 4.2.4.

0. 7 .14 Dose Due to Non-Noble Gas Radionuclides (Section A.1.4 of Appendix A)

The term dose in the title of Section A.1.4 of Appendix A includes both dose and dose commitment (see Section 4.1.1 ). This is based on its usage in the standard Technical Specifications (see Specification 3.11.2.3 of References 2 and 3).

The dose due to non-noble gas radionuclides is calculated by Equation A-7 of Appendix A. It is based on Section 5.3.1 of NUREG 0133.

July 2018

CY-8R-170-301 Revision 10 Page 150 of 353 0.7.15 Ground Deposition Dose (Section A.1.4.1 of Appendix A and Section 8.8 of Appendix B)

The dose due to deposited radionuclides is calculated by Equations A-7and A-8 of Appendix A. These equations are explained in Section 4.2.5. The methodology is based upon Sections 5.3.1 and 5.3.1.2 of NUREG 0133. The ground plane dose conversion factors DFGi used in Equation A-8 of Appendix A are identical to the dose factors provided in Table E-6 of R. G. 1.109.

Equation A-8 of Appendix A uses a value of 0.7 for the shielding factor which accounts for shielding due to occupancy of structures. This value is specified in Section 1 of Appendix B,Section II; of Regulatory Guide 1.109 and Section 5.3.1.2 of NUREG 0133.

0.7.16 Inhalation Dose (Section A.1.4.2 of Appendix A and Section B.9 of Appendix B)

The dose commitment due to inhalation is calculated by Equations A-7 and A-9 of Appendix A. This equation is explained in Section 4.2.6. It is based on Sections 5.3.11and 5.3.1.1 of NUREG 0133. The dose factors, DFAiia*

used in Equation A-9 of Appendix A for 10CFR50 Appendix I compliance are identical to the inhalation dose factors provided in Tables E-7 through E-10 of Regulatory Guide 1.109.

0.7.17 Food Pathways Doses (Section A.1.4.3 of Appendix A and Section 8.10 of Appendix 8)

The dose commitment due to food pathways is calculated by Equations A-7 and A-10 through A-15 of Appendix A. These equations are discussed in Section 4.2.7. They are based the methodology found in Sections 5.3.1.3 through 5.3.1.5 of NUREG 0133. The dose calculations for particulate and radioiodine account for doses resulting from dry deposition of radioactive materials onto the ground and foliage. Wet deposition is not considered in evaluating long-term-average environmental doses at the nuclear power stations for the reason put forth in Regulatory Guide 1.111 (see Page 1.111-12):

0.7.18 Inhalation Dose Rate (Section A.1.5 of Appendix A)

Inhalation dose commitment rate is calculated by Equation A-16 of Appendix A. This equation is explained in Section 4.2.6.

0.8 BASES OF LIQUID EFFLUENT CALCULATIONS (SECTION A.2 and Appendix 8; SECTION II)

This section presents bases of the methodology used to calculate doses and radioactivity concentrations due to releases of radioactivity in liquid effluents. The calculations use equations presented in Section A.2 of Appendix A. The equations involve transport and dose factors that are determined as described in Appendix B;Section II.

0.8.1 Dose (Section A.2.1 of Appendix A and Section 8.15 of Appendix B)

The dose due to radioactive materials in liquid effluents is calculated by Equations A-17 through A-20 of Appendix A. The dose is based upon the sum of contributions from drinking water (calculated by Equations A-17, A-18 and A-19 of Appendix A) and fish (calculated by Equations A-17, A-18 and A-20 of Appendix A). The equations are explained in Section 4.3 and Section B.15 of Appendix B. They are based on Sections 4.3 and 4.3.1 of NUREG 0133.

For all stations the flow and dilution parameters in Equations A-18 (Z) and A-18 (Ow) of Appendix A are determined using the river model (Section B.15.3.1.1 of Appendix B). For drinking water drawn downstream of Byron, Dresden, LaSalle, and Quad Cities Stations, this model assumes complete mixing of the station discharge with river water before withdrawal as potable water. This is based on the existence of one or more dams between the station liquid discharge and the water supply intake point. For drinking water drawn downstream of Braidwood Station, this model assumes partial mixing of the Station's discharge with river water before withdrawal as potable water. See Table 0-6 of this document.

i=:or fish, the river model assumes complete mixing in the near-field river flow (Z).

CY-BR-170-301 Revision 10 Page 151 of 353 0.8.2 Concentration Due to Tank Discharges (Section A.2.3 of Appendix A)

The concentration of radioactivity in tank discharges is calculated by Equation A-22 of Appendix A. The basis of this equation is explained in Section B.16 of Appendix B.

0.9 BASES OF CALCULATIONS OF DOSE DUE TO CONTAINED SOURCES (SECTION A.3)

Annual radiation doses due to contained sources of radioactivity at the nuclear power stations are judged to be negligible in comparison with applicable limits except for doses due to BWR turbine skyshine. This judgment is based on the considerations discussed in Section 0.3.3.

0.9.1 BWR Skyshine Dose 16 The dose due to N skyshine is calculated by Equation A-23 of Appendix A. This equation is based on the following:

• Measurements of dose rate due to skyshine made at Dresden, Quad Cities and LaSalle.

• An empirical fit to the above data (References 46, 47 and 48).

• Measurements of the radiological effects of hydrogen addition to primary coolant at Dresden 2 (Reference 83).

• Guidelines for BWR hydrogen water chemistry installations prepared by the Hydrogen Installation Subcommittee of the BWR Owners Group for lntragranular Stress Corrosion Cracking (Reference 39).

References 46 and 47 and provides a mathematical expression for calculating an upper bound to skyshine dose when there is no hydrogen addition to primary coolant. When there is hydrogen addition, the dose is multiplied by a factor of up to 10 depending on injection rates and power level. The value of this factor is based on data and guidelines in References 83 (see Page 4-13) and 39 (see Page 8-1).

Because of natural background radiation, it was only possible to measure skyshine dose rate only to about 600 meters from the turbines. Beyond this distance, the skyshine dose rate was so small that it was masked by fluctuations in the background radiation levels (see References 46, 47 and 48). Despite this, Equation A-23 of Appendix A is put forth here for use at greater distances. This is done because estimates of skyshine dose at distances above 600 meters are sometimes needed and because Equation A-23 of Appendix A is consistent with measurements at lower distances.

CY-BR-170-301 Revision 10 Page 152 of 353 0.9.2 Estimate of Dose Due to Other Facilities of the Uranium Fuel Cycle (Section A.5.2 of Appendix A)

In evaluating compliance with 40CFR190, radiation doses from other uranium fuel cycle facilities are treated as negligible except for contributions due to radioactive liquid effluents from the nuclear power stations. The reasons for evaluating the latter are conservatism and completeness. The other contributions are judged negligible on the following grounds:

• Doses due to direct radiation and airborne effluents decrease very rapidly as distance from a source or release point increases. For direct radiation, this is due to the shielding effects of air, to the 1/r2 falloff of radiation from a point source as distance r from the source increases, and to the exponential falloff of skyshine radiation (see Section A.3.2 of Appendix A). For airborne effluents, this is due to plume broadening, plume depletion, and the variability of wind direction (see Reference 18, especially Section 7-5.2).

• Doses due to radioactivity in liquid effluents are reduced by mixing, dilution, and plate out as water containing radioactivity moves away from the release point.

• Maximum offsite doses expected in the vicinities of uranium milling, conversion, enrichment, and fabrication facilities associated with electric power production have been shown to be less than 10CFR20 limits (see the references listed in Table 0-7 of this document). Their dose effects should be negligible in the vicinity of any nuclear power station since all such facilities are located more than 100 kilometers (62 miles) from any other nuclear power station (see Table 0-8 of this document).

• Maximum offsite doses from light-water-cooled nuclear power reactors are required to be below limits based on requirements in 10CFR20 and 10CFR50 Appendix I. The maximum offsite doses due to airborne effluents occur at or near the site boundary and decrease rapidly as distance from the site increases. Doses at the nuclear power stations due to other nuclear stations should be well below the limits of 10CFR20 and 10CFR50 Appendix I since all other nuclear power stations are at least 17 km (10 miles) distant from any station (see Table 0-9 of this document).

• Standard Radiological Effluent Technical Specifications (References 2 and 3)/RETS and the Technical Specifications of the Byron, Braidwood and LaSalle stations allow neglect of doses due to nuclear fuel cycle facilities more than 8 kilometers (5 miles) distant (see Bases Section 12.4 for Byron, Braidwood and LaSalle.).

• The only uranium fuel cycle facility within 8 kilometers of a nuclear power station is the General Electric (GE) Company's Morris Operation at Morris, Illinois, adjacent to the Dresden. This facility is used for storage of spent fuel. Releases of radioactivity from the facility are very low (see Pages 8-1 and 8-2 of Reference 89). Ventilation air from areas of actual and potential contamination passes through a sand filter and a 300-foot high stack before release. In the period July 1974 through December 1982, maximum offsite gross beta activity never exceeded 1 E-18 µCi/cc averaged over a 6-month period. This concentration may be compared to the derived air concentrations (DAC) given in 10CFR20 Appendix B; Table 2 for members of the public. Exposure to the DAC corresponds to an annual dose of 50 mrem/year. As the Morris facility results in an airborne concentration many decades below the DACs, the corresponding dose is similarly negligible. Therefore, no further consideration of this facility is required for 40CFR190 analysis.

Per Braidwood ER, Table 5.2-7, and Reference 91. Except for potable water and fish, these values are based on water in the discharge canal. For potable water, the point of consumption is Wilmington, IL. For fish, it is assumed that they are caught in the Kankakee River.

Per Byron ER, Table 5.2-7. Except for drinking water (see Footnote e), these values are based on water in the discharge canal.

The value in the Byron ER is based on drinking discharge canal water. The value in this table is derived by dividing the Byron ER value by 167 to account for dilution in the Rock River. This dilution factor is based on the assumption of an annual cooling tower flow rate of 30 cfs (see Byron FSAR Section 5.2.4.1) and a Rock River flow rate of 5000 cfs (per Byron ER Section 2.4.1.2). (The plant discharges liquid to the Rock River at a point approximately 115 miles above the confluence of the Rock and Mississippi Rivers. There are no public potable water intakes on the Rock River.)

CY-BR-170-301 Revision 10 Page 167 of 353 CHAPTER 10 RADIOACTIVE EFFLUENT TREATMENT AND MONITORING 10.1 AIRBORNE RELEASES 10.1.1 System Description A simplified HVAC and gaseous effluent flow diagram is provided in Figure 10-1. The principal release points for potentially radioactive airborne effluents are the two auxiliary building vent stacks (designated Unit 1 Vent Stack and Unit 2 Vent Stack in Figure 10-1 ). In the classification scheme of Section 4.1.4, each is classified as a vent release point (see Table A-1 of Appendix A).

10.1.1.1 Waste Gas Holdup System The waste gas holdup system is designed and installed to reduce radioactive gaseous effluents by collecting reactor coolant system off-gases from the reactor coolant system and providing for delay or holdup to reduce the total radioactivity by radiodecay prior to release to the environment. The system is described in Chapter 11 of the Byron/Braidwood UFSAR.

10.1.1.2 Ventilation Exhaust Treatment System Ventilation exhaust treatment systems are designed and installed to reduce gaseous radioiodine or radioactive material in particulate form in gaseous effluents by passing ventilation or vent exhaust gases through HEPA filters (and charcoal adsorbers when required to mitigate potential iodine releases) prior to release to the environment.

Such a system is not considered to have any effect on noble gas effluents. The ventilation exhaust treatment systems are shown in Figure 10-1.

Engineered safety features atmospheric cleanup systems are not considered to be ventilation exhaust treatment system components.

10.1.2 Radiation Monitors 10.1.2.1 Auxiliary Building Vent Effluent Monitors Monitors 1RE-PR028 (Unit 1) and 2RE-PR028 (Unit 2) continuously monitor the final effluent from the auxiliary building vent stacks.

Both vent stack monitors feature automatic isokinetic sampling, grab sampling, and tritium sampling.

No automatic isolation or control functions are performed by these monitors. Pertinent information on these monitors is provided in Byron/Braidwood UFSAR Table 11.5-1.

July 2018

CY-BR-170-301 Revision 10 Page 168 of 353 10.1.2.2 Containment Purge Effluent Monitors Monitors 1RE-PR001 (Unit 1) and 2RE-PR001 (Unit 2) continuously monitor the effluent from the Unit 1 and Unit 2 containments, respectively. When airborne radioactivity in the containment purge effluent stream exceeds a specified level, station personnel will follow established procedures to terminate the release by manually activating the containment purge valves. Additionally, the auxiliary building vent effluent monitors provide an independent, redundant means of monitoring the containment purge effluent.

No automatic isolation or control functions are performed by these monitors.

Pertinent information on these monitors is provided in Byron/Braidwood UFSAR Table 11.5-1.

Area Radiation Monitors 1(2) RE-AR011 and 1(2) RE-AR012 monitor the containment atmosphere. On high alarm during a containment purge, these monitors will automatically terminate the purge.

10.1.2.3 Waste Gas Decay Tank Monitors Monitors ORE-PR002A/B continuously monitor the noble gas activity released from the gas decay tanks.

On high alarm, the monitors automatically initiate closure of the valve OGW014 thus terminating the release.

Pertinent information on these monitors and associated control devices is provided in Byron/Braidwood UFSAR Table 11.5-1.

10.1.2.4 Gland Steam and Condenser Air Ejector Monitors Monitors 1RE-PR027 and 2RE-PR027 continuously monitor the condenser air ejector gas from Units 1 and 2, respectively. No control devices are initiated by these channels.

Pertinent information on these monitors is provided in Byron/Braidwood UFSAR Table 11.5-1.

10.1.2.5 Radwaste Building Ventilation Monitor Monitor ORE-PR026 continuously monitors radioactivity in the radwaste building ventilation system. No control device is initiated by this channel.

Pertinent information on this monitor is provided in Byron/Braidwood UFSAR Table 11.5-1.

10.1.2.6 Component Cooling Water Monitor Monitor ORE-PR009 (common), 1RE-PR009 (Unit 1), and 2RE-PR009 (Unit 2) continuously monitor the component cooling water heat exchanger outlets. On high alarm, ORE-PR009 initiates closure of both component cooling water surge tank (CCWST) vents, 1RE-PR009 initiates closure of the Unit 1 CCWST vent, and 2RE-PR009 initiates closure of the Unit 2 CCWST vent.

10.1.2.7 Miscellaneous Ventilation Monitors Monitor ORE-PR003 continuously monitors radioactivity in the ventilation exhaust from the laboratory fume hoods.

No control device is initiated by this channel.

Pertinent information on this monitor and associated devices is provided in Byron/Braidwood UFSAR Table 11.5-1.

The Alert Alarm setpoint for the High Range Gas Channel is established at a fraction of the maximum release rate for the station.

The High Alarm setpoint for the Low Range Noble Gas Channel (1/2PR0288) is established at less than or equal to 50% of the maximum release rate for the station as calculated in 10.1.3.2. The Alert Alarm setpoint for the Low Range Gas Channel is established at a fraction of the High Alarm setpoint for the Low Range Noble Gas Channel.

10.1.3.1.2 Containment Purge Effluent Monitors The setpoints are established at 1.50 times the analyzed containment noble gas activity during purge, plus the background reading of the monitor prior to purge.

10.1.3.1.3 Waste Gas Decay Tank Effluent Monitors The setpoints are established at 1.50 times the analyzed waste gas tank activity during release.

10.1.3.2 Release Limits Alarm and trip setpoints of gaseous effluent monitors are established to ensure that the release rate limits of RETS are not exceeded. The release limits are found by solving Equations 10-1 and 10-2 for the total allowed release rate of vent releases, Otv*

(x:/Q)~QtvLK 1 f 1 <500mrem/yr (10-1)

I Q1v:Lt1 {L 1 (x:/Q)v + (1.11) M1 (x/Q)~ }< 3000 mrem/yr (10-2)

I The summations are over noble gas radionuclides i.

f; Fractional Radionuclide Composition The release rate of noble gas radionuclide i divided by the total release rate of all noble gas radionuclides.

Total Allowed Release Rate, Vent Release [~tCi/sec]

The total allowed release rate of all noble gas radionuclides released as vent releases.

The remaining parameters in Equation 10-1 have the same definitions as in Equation A-5 of Appendix A. The remaining parameters in Equation 10-2 have the same definition as in Equation A-6 of Appendix A.

Equation 10-1 is based on Equation A-5 of Appendix A and the RETS restriction on whole body dose rate (500 mrem/yr) due to noble gases released in gaseous effluents (see Section A.1.3.1 of Appendix A). Equation 10-2 is based on Equation A-6 of Appendix A and the RETS restriction on skin dose rate (3000 mrem/yr) due to noble gases released in gaseous effluents (see Section A.1.3.2 of Appendix A).

July 2018

CY-BR-170-301 Revision 10 Page 170 of 353 Since the solution to Equation 10-2 is more conservative than the solution to Equation 10-1, the value of Equation 5

10-2 (7.02 x 10 µCi/sec) is used as the limiting noble gas release rate. During evolutions involving releases from the containment or waste gas decay tanks, the release rate from each release path is procedurally limited to 1 x 105 µCi/sec.

Calibration methods and surveillance frequency for the monitors will be conducted as specified in the RETS.

10.1.3.3 Release Mixture In the determination of alarm and trip setpoints, the radioactivity mixture in exhaust air is assumed to have the radionuclide composition of Table 10-1.

10.1.3.4 Conversion Factors The response curves used to determine the monitor count rates are based on the sensitivity to Xe-133 for conservatism.

10.1.3.5 HVAC Flow Rates The plant vent stack flow rates are obtained from 1/2 PR28J. However, if the readout indicates "O" flow, the following minimum rated fan flow values are currently used:

6 Unit 1 - 6.15x10 cc/sec 6

Unit 2 - 4.55 x 10 cc/sec 10.1.4 Allocation of Effluents from Common Release Points Radioactive gaseous effluents released from the auxiliary building, miscellaneous ventilation systems and the gas decay tanks are comprised of contributions from both units. Consequently, allocation is made evenly between units.

10.1.5 Dose Projections for Batch Releases Dose projections are not made prior to release. Doses are calculated after purging the containment or venting the waste gas decay tanks. Per procedure, representative samples are obtained and analyzed, and the doses calculated on a monthly basis to verify compliance with 10CFR50.

10.2 LIQUID RELEASES 10.2.1 System Description A simplified liquid effluent flow diagram is provided in Figure 10-3. A simplified liquid waste processing diagram is provided in Figure 10-2.

The liquid radwaste treatment system is designed and installed to reduce radioactive liquid effluents by collecting the liquids, providing for retention or holdup, and providing for treatment by demineralizer or a concentrator for the purpose of reducing the total radioactivity prior to release to the environment. The system is described in Chapter 11 of the Byron/Braidwood UFSAR.

10.2.1.1 Release Tanks There are two radwaste release tanks (OWX01T and OWX26T) which receive liquid waste before discharge to the Kankakee river.

July 2018

CY-BR-170-301 Revision 10 Page 171 of 353 10.2.1.2 Historical Groundwater Remediation Temporary groundwater remediation activities at the Exelon Pond, at Vacuum Breaker #1, and west of the Turbine Building completed in 2013. These pathways are retired, but descriptions of the monitoring pathways remain in the ODCM for historical reference.

Groundwater from the Exelon Pond and from the area near Vacuum Breaker #1 was pumped into the Circulating Water Slowdown (CWBD) line. Groundwater from the area west of the Turbine Building was pumped into the Circulating Water Return line to the Braidwood Station Cooling Lake. A composite sampler was installed at each location to monitor the radioactivity of the water pumped from the pond and from the ground.

A composite sampler was installed at each of the station's continuous release paths at Circulating Water Slowdown, Condensate Polisher Sump, and Waste Water Treatment. The samplers were used to monitor radioactivity that is released via these paths. An alternate path exists to direct the discharge of Waste Water Treatment to the Circulating Water Slowdown release path.

Simplified diagrams of these process flows are shown in Figure 10.2 and 10.3.

10.2.2 Radiation Monitors 10.2.2.1 Liquid Radwaste Effluent Monitors Monitors ORE-PR001/0RE-PR090 are used to monitor all releases from the release tanks. On high alarm, the monitor automatically initiates closure of valves OWX-353 and OWX-896 to terminate the release.

Pertinent information on the monitor and associated control devices is provided in Byron/Braidwood UFSAR Table 11.5-2.

10.2.2.2 Station Slowdown Monitor Monitor ORE-PR010 continuously monitors the circulating water blowdown. No control device is initiated by this channel.

Pertinent information on this monitor is provided in Byron/Braidwood UFSAR Table 11.5-2.

10.2.2.3 Reactor Containment Fan Cooler (RCFC) and Essential Service Water (ESSW) Outlet Line Monitors Monitors 1RE-PR002, 2RE-PR002, 1RE-PR003, and 2RE-PR003 continuously monitor the RCFC and ESSW outlet lines.

No control device is initiated by these channels.

Pertinent information on these monitors is provided in Byron/Braidwood UFSAR Table 11.5-2.

10.2.2.4 Turbine Building Fire and Oil Sump Monitor Monitor ORE-PRODS continuously monitors the fire and oil sump discharge. On high alarm the monitor automatically initiates an interlock to trip the discharge pumps, close valve 000030, and terminate the release.

Pertinent information on this monitor is provided in Byron/Braidwood UFSAR Table 11.5-2.

10.2.2.5 Condensate Polisher Sump Monitor Monitor ORE-PR041 continuously monitors the condensate polisher sump discharge. On high alarm the monitor automatically initiates an interlock to trip the discharge pumps and terminate the release.

July 2018

CY-BR-170-301 Revision 10 Page 172 of 353 Pertinent information on this monitor is provided in Byron/Braidwood UFSAR Table 11.5-2.

10.2.3 Alarm and Trip Setpoints 10.2.3.1 Setpoint Calculations Alarm and trip setpoints of liquid effluent monitors at the principal release points are established to ensure that the limits of RETS and 10CFR20 are not exceeded in the unrestricted area.

10.2.3.1.1 Station Slowdown Monitor The monitor setpoint is found by solving equation 10-3.

10.2.3.1.2 Liquid Radwaste Effluent Monitor During release the setpoint is established at 1.5 times the analyzed tank activity plus the background reading.

10.2.3.1.2.1 Release Tank Discharge Flow Rate Prior to each batch release, a grab sample is obtained.

The results of the analysis of the waste sample determine the discharge rate of each batch as follows:

10 Multiplier 10.2.3.1.2.2 Release Limits Release limits are determined from RETS. Discharge rates and setpoints are adjusted to ensure that 50% of applicable RETS are not exceeded. (See Section 10.2.3.1.2.1.)

In addition to the limits identified within the RETS, an administrative action level for tritium has been established for the Braidwood cooling pond. This limit, based on drinking water pathways, has been established as a control mechanism to ensure this pathway does not become a significant contributor to public dose. Because the public has access to the Braidwood cooling pond for fishing and/or boating, an administrative limit for discharges to the cooling pond is prudent to ensure dose to the public from this path remains well below limits.

The controls for this pathway will be established by limiting the quantity (Curies) discharged to the Braidwood cooling pond. The administrative action level will be established at 4 Ci/year. During times when tritium discharged to the cooling pond is in excess of the 4 Ci/year administrative action level, cooling pond tritium samples should be collected and analyzed (tritium LLD as defined in ODCM Chapter 12, Table 12.3-1) in order to assess actual tritium cooling pond tritium concentrations. Effluent pathways to the cooling pond are analyzed for tritium in accordance with ODCM Chapter 12, Table 12.3-1.

The administrative action level was chosen based on an equilibrium concentration of 200 pCi/I in the cooling pond water (1 % of the public drinking water limit as specified in 40CFR141.) Information regarding calculation and assumptions can be found in Braidwood Health Physics Technical Document 98-001, "Cooling pond tritium issues."

10.2.3.1.2.3 Release Mixture For monitors ORE-PR001 and ORE-PR010 the release mixture used for the setpoint determination is the radionuclide mix identified in the grab sample isotopic analysis or the mix in Table 10-2.

Release mixtures are based on a representative isotopic mixture of the waste stream or inputs to the waste stream, or defaulted to the mix listed in Table 10-2.

July 2018

CY-BR-170-301 Revision 10 Page 175 of 353 10.2.3.1.4 Conversion Factors The readouts for the liquid effluent monitors are in µCi/ml. The cpm to µCi/ml conversion is determined for each monitor.

10.2.4 Allocation of Effluents from Common Release Points Radioactive liquid effluents released from either release tank (OWX01T or OWX26T) are comprised of contributions from both units. Under normal operating conditions, it is difficult to apportion the radioactivity between the units. Consequently, allocation is made evenly between units.

10.3 SOLIDIFICATION OF WASTE/PROCESS CONTROL PROGRAM The process control program (PCP) contains the sampling, analysis, and formulation determination by which solidification of radioactive wastes from liquid systems is ensured.

Figure 10-4 is a simplified diagram of solid radwaste processing system.

This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within: (1) the Section II.A design objectives of Appendix I, 10CFR50, to a MEMBER OF THE PUBLIC, and (2) the limits of 10CFR20.1301.

This section applies to the release of radioactive materials in liquid effluents from all units at the site.

2. During any calendar year to less than or equal to 3 mrems to the whole body and to less than or equal to 10 mrems to any organ.

Applicability: At all times.

Action:

1. With the calculated dose from the release of radioactive materials in liquid effluents exceeding any of the above limits, prepare and submit to the Commission within 30 days, pursuant to 10CFR50 Appendix I, Section IV.A, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions that have been taken to reduce the releases and the proposed corrective actions to be taken to assure that subsequent releases will be in compliance with the above limits.

Surveillance Requirements 12.3.2. B Cumulative dose contributions from liquid effluents for the current calendar quarter and the current calendar year shall be determined in accordance with the methodology and parameters in the ODCM at least once per 31 days.

12.3.2.C This section is provided to implement the requirements of Sections II.A, Ill.A and IV.A of Appendix I, 10CFR50. The Operability Requirements implement the guides set forth in Section II.A of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." The dose calculation methodology and parameters in the ODCM implement the requirements in Section Ill.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.

The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man From Routine Releases of Reactor Effluents For the Purpose of Evaluating Compliance with 10CFR50, Appendix I" Revision 1, October 1977, Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I,"

This section applies to the release of radioactive materials in liquid effluents from each reactor at the site. When shared Radwaste Treatment Systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the Radwaste Treatment System. For determining conformance to Operability Requirements, these allocations from shared Radwaste Treatment Systems are to be added to the releases specifically attributed to each unit to obtain the total releases per unit.

Applicability: At all times.

Action:

1. With radioactive liquid waste being discharged without treatment and in excess of the above limits and any portion of the Liquid Radwaste Treatment System not in operation, prepare and submit to the Commission within 30 days, pursuant to 10CFR50 Appendix I, Section IV.A, a Special Report that includes the following information:

a. Explanation of why liquid radwaste was being discharged without treatment, identification of any inoperable equipment or subsystems, and the reason for the inoperability,

b. Action(s) taken to restore the inoperable equipment to OPERABLE status, and

c. Summary description of action(s) taken to prevent a recurrence.

Surveillance Requirements 12.3.3.B.1 Doses due to liquid releases from each unit to UNRESTRICTED AREAS shall be projected at least once per 31 days in accordance with the methodology and parameters in the ODCM when the Liquid Radwaste Treatment System is not being fully utilized.

12.3.3.8.2 The installed Liquid Radwaste Treatment System shall be considered OPERABLE by meeting Sections 12.3.1.A and 12.3.2.A.

12.3.3.C The OPERABILITY of the Liquid Radwaste Treatment System ensures that this system will be available for use whenever liquid effluents require treatment prior to release to the environment. The requirement that the appropriate portions of this system be used when specified provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable". This section implements the requirements of 10CFR50.36a, General Design Criterion 60 of Appendix A to 10CFRSO and the design objective given in Section 11.D of Appendix I to 10CFR50.

This section applies to the release of radioactive materials in liquid effluents from each unit at the site. When shared Radwaste Treatment Systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the Radwaste Treatment System.

C This section is provides reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a Member of the Public in an Unrestricted Area, either at or beyond the Site Boundary in excess of the design objectives of appendix I to 10 CFR part 50. This specification is provided to ensure that gaseous effluents from all units on the site will be appropriately controlled. It provides operational flexibility for releasing gaseous effluents to satisfy the Section II.A and II. design objectives of appendix I to 10 CFR part 50.

For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of that MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY.

Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, shall be given in the ODCM. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrems/year to the whole body or to less than or equal to 3000 mrems/year to the skin. These release rate limits also restrict, at all times the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrems/year.

This section applies to the release of radioactive materials in gaseous effluents from all units at the site.

The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs). Detailed discussion of the LLD, and other detection limits can be found in HASL Procedures Manual, HASL-300 (revised annually),

probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system, which may include radiochemical separation:

Ex V x 2.22x106 xYxexp(-llM)

Where:

LLD =the lower limit of detection (microCuries per unit mass or volume),

sb = the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (counts per minute),

E =the counting efficiency (counts per disintegration),

V =the sample size (units of mass or volume),

/...=the radioactive decay constant for the particular radionuclide (sec - ), and

.M =the elapsed time between the midpoint of sample collection and the time of counting (sec).

Typical values of E, V, Y, and At should be used in the calculation.

Alternate LLD Methodology An alternate methodology for LLD determination follows and is similar to the above LLD equation:

(k=value of the t statistic from the single-tailed t distribution at a significance level of 0.95 and infinite degrees of freedom. This means that the LLD result represents a 95%

detection probability with a 5% probability of falsely concluding that the nuclide present when it is not or that the nuclide is not present when it is.)

t.. =radioactive decay constant, (units consistent with .M, RT and Td) tit= "delta t", or the elapsed time between sample collection or the midpoint of sample collection and the time the count is started, depending on the type of sample, (units consistent with "A)

RT= elapsed real time, or the duration of the sample count, (units consistent with t..)

Td =sample deposition time, or the duration of analyte collection onto the sample media, (unit consistent with "A)

The LLD may be determined using installed radioanalytical software, if available. In addition to determining the correct number of channels over which to total the background sum, utilizing the software's ability to perform decay corrections (i.e. during sample collection, from sample collection to start of analysis and during counting), this alternate method will result in a more accurate determination of the LLD.

It should be recognized that the LLD is defined as a before the fact limit and not as an after the fact limit for a particular measurement.

1. During any calendar quarter: Less than or equal to 5 mrads for gamma radiation and less than or equal to 10 mrads for beta radiation, and

2. During any calendar year: Less than or equal to 10 mrads for gamma radiation and less than or equal to 20 mrads for beta radiation.

Applicability: At all times.

Action:

1. With the calculated air dose from radioactive noble gases in gaseous effluents exceeding any of the above limits, prepare and submit to the Commission within 30 days, pursuant to 10CFRSO Appendix I,Section IV.A, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions that have been taken to reduce the releases and the proposed corrective actions to be taken to assure that subsequent releases will be in compliance with the above limits.

CY-BR-170-301 Revision 10 Page 235 of 353 12.4.2 Dose - Noble Gases (Continued)

The dose calculation methodology and parameters established in the ODCM for calculating the doses due to the actual release rates of radioactive materials in gaseous effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man From Routine Releases of Reactor Effluents For the Purpose of Evaluating Compliance with 10CFR50, Appendix I" Revision 1, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors, Revision 1," July 1977. The ODCM equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

This section applies to the release of radioactive materials in gaseous effluents from each unit at the site. When shared Radwaste Treatment Systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the Radwaste Treatment System. For determining conformance to Operability Requirements, these allocations from shared Radwaste Treatment Systems are to be added to the releases specifically attributed to each unit to obtain the total releases per unit.

2. During any calendar year: Less than or equal to 15 mrems to any organ.

Applicability: At all times.

Action:

1. With the calculated dose from the release of lodine-131 and 133, tritium, and radionuclides in particulate form with half-lives greater than 8 days, in gaseous effluents exceeding any of the above limits, prepare and submit to the Commission within 30 days, pursuant to 10CFR50 Appendix I, Section IV.A, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions that have been taken to reduce the releases and the proposed corrective actions to be taken to assure that subsequent releases will be in compliance with the above limits.

Surveillance Requirements 12.4.3.B Cumulative dose contributions for the current calendar quarter and the current calendar year for lodine-131 and 133, tritium, and radionuclides in particulate form with half-lives greater than 8 days shall be determined in accordance with the methodology and parameters in the ODCM at least once per 31 days.

12.4.3.C This section is provided to implement the requirements of Sections 11.C, Ill.A and IV.A of Appendix I, 10CFR50. The Operability Requirements are the guides set forth in Section 11.C of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents to areas at or beyond the SITE BOUNDARY will be kept "as low as is reasonable achievable."

CY-BR-170-301 Revision 10 Page 237 of 353 12.4.3 Dose (Continued)

The ODCM calculation methodology and parameters for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man From Routine Releases of Reactor Effluents For the Purpose of Evaluating Compliance with 10CFR50, Appendix I" Revision 1, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors," Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate specifications for lodine-131 and 133, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent upon the existing radionuclide pathways to man, in the areas at and beyond the SITE BOUNDARY. The pathways that were examined in the development of these calculations were: (1) individual inhalation of airborne radionuclides, (2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, (3) deposition onto grassy areas where milk animals and meat producing animal's graze with consumption of the milk and meat by man, and (4) deposition on the ground with subsequent exposure to man.

This section applies to the release of radioactive materials in gaseous effluents from each unit at the site. When shared Radwaste Treatment Systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the Radwaste Treatment System. For determining conformance to Operability Requirements, these allocations from shared Radwaste Treatment Systems are to be added to the releases specifically attributed to each unit to obtain the total releases per unit.

1. 0.2 mrad to air from gamma radiation, or

2. 0.4 mrad to air from beta radiation, or

3. 0.3 mrem to any organ of a MEMBER OF THE PUBLIC.

Applicability: At all times.

Action:

CY-BR-170-301 Revision 10 Page 239 of 353 12.4.4 Gaseous Radwaste Treatment System (Continued)

The requirement that the appropriate portions of this system be used when specified provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable". This section implements the requirements of 10CFR50.36a, General Design Criterion 60 of Appendix A to 10CFR50 and the design objective given in Section 11.D of Appendix I to 10CFR50. The specified limits governing the use of appropriate portions of the Gaseous Radwaste Treatment System were specified as a 2% fraction of the dose design objectives set forth in Section 11. B and 11. C of Appendix I, 10CFR50, for gaseous effluents.

This section applies to the release of radioactive materials in gaseous effluents from each unit at the site. When shared Radwaste Treatment Systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the Radwaste Treatment System.

CY-BR-170-301 Revision 10 Page 240 of 353 12.4.5 Total Dose Operability Requirements 12.4.5.A The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.

Applicability: At all times.

Action:

1. With the calculated doses from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of Sections 12.3.2, 12.4.2, or 12.4.3, calculations should be made including direct radiation contributions from the units and from outside storage tanks to determine whether the above limits of Section 12.4.5.A have been exceeded. If such is the case, prepare and submit to the Commission within 30 days, a Special Report that defines the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and includes the schedule for achieving conformance with the above limits. This Special Report, as defined in 10CFR20.2203, shall include an analysis that estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentration of radioactive material involved, and the cause of the exposure levels or concentrations.

If the estimated dose(s) exceeds the above limits, and if the release condition resulting in violation of 40CFR190 has not already been corrected, the Special Report shall include a request for a variance in accordance with the provisions of 40CFR190.

Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.

Surveillance Requirements 12.4.5.B.1 Cumulative dose contributions from liquid and gaseous effluents shall be determined in accordance with Sections 12.3.2, 12.4.2, and 12.4.3, and in accordance with the methodology and parameters in the ODCM.

12.4.5.B.2 Cumulative dose contributions from direct radiation from the units and from radwaste storage tanks shall be determined in accordance with the methodology and parameters in the ODCM.

This requirement is applicable only under conditions set forth in ACTION 1 of Section 12.4.5.A.

12.4.5.B.3 Initial estimates of expected dose rates at the Old Steam Generator Storage Facility (OSGSF) are provided through calculations. After the old steam generators are placed in the facility and the equipment opening is sealed, a radiation survey of the walls and roof will be performed. The measured dose rates will be used for comparison to the calculated dose rates and to confirm or adjust the initial estimates for use in 10CFR20, 10CFR50 Appendix I, and 40CFR190 compliance determinations.

Ju1y201s I

CY-BR-170-301 Revision 10 Page 241 of 353 12.4.5 Total Dose (Continued)

Surveillance Requirements Environmental dosimeters are located near the OSGSF. The dosimeters are processed quarterly to determine the dose at the locations for use in compliance determinations.

Quarterly monitoring of the sump for indications of liquid is performed and, if liquid is present and seepage appears to have occurred, a sample will be taken and analyzed.

12.4.5.C.1 This section is provided to meet the dose limitations of 40CFR190 that have been incorporated into 10CFR20 by 46FR18525. The section requires the preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40CFR190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiation doses from the reactor units and outside storage tanks are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40CFR190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40CFR190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40CFR190 have not already been corrected), in accordance with the provisions of 40CFR190.11 and 10CFR20.2203, is considered to be a timely request and fulfills the requirements of 40CFR190 until NRC staff action is completed. The variance only relates to the limits of 40CFR190, and does not apply in any way to the other requirements for dose limitation of 10CFR20, as addressed in Sections 12.3.1and12.4.1. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

12.4.5. C.2 The OSGSF was constructed to provide long-term storage of the four old steam generators removed from Braidwood Station Unit 1 during the Steam Generator Replacement Outage.

The facility is designed to ensure that the dose rates at the wall and roof meet the limits of 10CFR20 (UFSAR Zone 1-A for the walls and Zone 1-8 for the roof). The facility is also designed to ensure that the dose rates at the site boundary and to the nearest resident meet the limits of 10CFR20 and 40CFR190.

The OSGSF design includes 2'-6" thick concrete walls and 1 '-6" inch thick concrete roof.

Personnel access is through a labyrinth-style vestibule with a locked exterior door and a lockable sliding door for access beyond the vestibule to the interior of the facility. A water collection sump is provided with access from the vestibule for sampling water if liquid is present. The opening used for placement of the steam generators inside the facility will be sealed with concrete panels. The panels have a tongue and groove design to preclude radiation "shine" after installation.

CY-BR-170-301 Revision 10 Page 242 of 353 12.4.5 Total Dose {Continued)

The potential for radiological release from the OSGSF is also minimized by sealing openings in the steam generators caused by removed piping with welded structural cover plates or seal plugs. Trunnions installed during removal of the old steam generators from the containment and existing opening covers remain attached to the steam generators to ensure the penetrations are leaktight. External exposed surfaces of the steam generators are coated to seal and fix surface contamination to the steam generators.

12.4.5.C.3 The ISFSI was designed and constructed to provide long-term dry cask storage of spent fuel assemblies with doses to members of the public with the limits of 10CFR72.104. Holtec International (Holtec) HI-STORM 100 Cask System (HI-STORM) for the storage of BWNPS

.Units 1 and 2 spent fuel utilizes storage modules containing dry shielded canisters of spent fuel designed to prevent liquid or gaseous effluent releases of radioactive materials.

Operation of the ISFSI does not create any radioactive materials or result in any credible liquid or gaseous effluent release. During normal operations and anticipated occurrences, the annual dose equivalent to any real individual who is located beyond the controlled area must not exceed 0.25 mSv (25 mrem) to the whole body, 0.75 mSv (75 mrem) to the thyroid and 0.25 mSv (25 mrem) to any other critical organ as a result of exposure to:

1. Planned discharges of radioactive materials, radon and its decay products excepted, to the general environment,

2. Direct radiation from ISFSI or MRS operations, and

3. Any other radiation from uranium fuel cycle operations within the region.

In addition, the dose in any unrestricted area from external sources does not exceed 2 mrem in any one hour. The Effluents Program shall implement monitoring, sampling and analysis of radioactive liquid and gaseous effluents in accordance with 10CFR20.1302 and with the methodology and parameters in the ODCM.

Applicability: At all times.

Action:

1. With the Radiological Environmental Monitoring Program not being conducted as specified in Table 12.5-1, prepare and :submit to the Commission, in the Annual Radiological Environmental Operating Report required by Section 12.6.1, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence.

Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of sampling equipment, if a person/business who participates in this program goes out of business or no longer can provide sample, or contractor omission which is corrected as soon as discovered. If the equipment malfunctions, corrective actions shall be completed as soon as practical. If a person/business supplying samples goes out of business, a replacement supplier shall be found as soon as possible. All deviations from the sampling schedule will be described in the Annual Radiological Environmental Operating Report.

2. With the level of radioactivity as the result of plant effluents in an environmental sampling medium at a specified location exceeding the reporting levels of Table 12.5-2 when averaged over any calendar quarter, prepare and submit to the Commission within 30 days, pursuant to 10CFR50 Appendix I, Section IV.A, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce radioactive effluents so that the potential annual dose* to a MEMBER OF THE PUBLIC is less than the calendar year limits of Section 12.3.2, 12.4.2, or 12.4.3. When more than one of the radionuclides in Table 12.5.2 are detected in the sampling medium, this report shall be submitted if:

concentration (1) + concentration (2) + .. . ~1. 0 reporting level (1) reporting level (2)

When radionuclides other than those in Table 12.5-2 are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose* to A MEMBER OF THE PUBLIC from all radionuclides is equal to or greater than the calendar year limits of Section 12.3.2, 12.4.2, or 12.4.3. This report is not required if the measured level of radioactivity was not the result of plant effluents; however, in such an event, the condition shall be reported and described in the Annual Radiological Environmental Operating Report required by Section 12.6.1.

• The methodology and parameters used to estimate the potential annual dose to a MEMBER OF THE PUBLIC shall be indicated in this report.

3. If the sample type or sampling location(s) as required by Table 12.5-1 become(s) permanently unavailable, identify suitable alternative sampling media for the pathway of interest and/or specific sampling locations for obtaining replacement samples and add them to the Radiological Environmental Monitoring Program as soon as practicable. The specific locations from which samples were unavailable may then be deleted from the monitoring program.

Prepare and submit a controlled version of the ODCM within 180 days including a revised figure(s) and table reflecting the new location(s) with supporting information identifying the cause of the unavailability of samples and justifying the selection of new location(s) for obtaining samples.

Surveillance Requirements 12.5.1. B The radiological environmental monitoring program samples shall be collected pursuant to Table 12.5-1 from the specific locations given in the table and figure(s) in the ODCM, and shall be analyzed pursuant to the requirements of Table 12.5-1 and the detection capabilities required by Table 12.5-3.

12.5.1.C The Radiological Environmental Monitoring Program required by this section provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10CFR50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring. The initially specified monitoring program will be effective for at least the first 3 years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs). The LLDs required by Table 12.5-3 are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as a before the fact limit representing the capability of a measurement system and not as an after the fact limit for a particular measurement.

Detailed discussion of the LLD, and other detection limits, can be found in HASL procedures Manual, HASL-300 (revised annually), Currie, LA., "Limits for Qualitative Detection and Quantitative Determination -Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968),

Radiological Environmental Monitoring Program Table Notations (1) Specific parameters of distance and direction from the centerline of the midpoint of the two units and additional description where pertinent, shall be provided for each and every sample location in Table 12.5-1 of the ODCM Station Annexes. Refer to NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants," October 1978, and to Radiological Assessment Branch Technical Position, Revision 1, November 1979.

(2) Far field samples are analyzed when the respective near field sample results are inconsistent with previous measurements and radioactivity is confirmed as having its origin in airborne effluents from the station, or at the discretion of the Radiation Protection Director.

(3) Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or more after sampling to allow for radon and thoron daughter decay. If gross beta activity in air particulate samples is greater than 10 times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

(4) Gamma isotopic analysis means the identification and quantification of gamma emitting radionuclides that may be attributable to the effluents from the station.

(5) Other instruments, such as a pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. Film badges shall not be used as dosimeters for measuring direct radiation. The 40 locations is not an absolute number. The number of direct radiation monitoring stations may be reduced according to geographical limitations; e.g., If a station is adjacent to a lake, some sectors may be over water thereby reducing the number of dosimeters which could be placed at the indicated distances. The frequency of analysis or readout for dosimeter systems will depend upon the characteristics of the specific system used and should be selected to obtain optimum dose information with minimal fading.

(6) Groundwater samples shall be taken when this source is tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties are suitable for contamination.

(7) The "downstream" sample shall be taken in an area beyond but near the mixing zone. The "upstream sample" shall be taken at a distance beyond significant influence of the discharge.

Upstream samples in an estuary must be taken far enough upstream to be beyond the station influence.

(8) If milking animals are not found in the designated indicator locations, or if the owners decline to participate in the REMP, all milk sampling may be discontinued. If no indicator milk sample is available, then vegetation samples, as described in 4.d. Vegetation, must be obtained.

(9) Biweekly refers to every two weeks.

(10) 1-131 analysis means the analytical separation and counting procedure are specific for this radionuclide.

(11) One sample shall consist of a volume/weight of sample large enough to fill contractor specified container.

Applicability: At all times.

Action:

i

1. With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment, via the same exposure pathway 20% greater than at a location from which samples are currently being obtained in accordance with Section 12.5.1, add the new location(s) within 30 days to the Radiological Environmental Monitoring Program given in Chapter 11. The sampling location(s), excluding the control location, having the lowest calculated dose or dose commitment(s), via the same exposure pathway, may be deleted from this monitoring program after October 31 of the year in which this Land Use Census was conducted. Submit in the next Annual Radiological Environmental Operating Report documentation for a change in the ODCM including a revised figure(s) and table(s) for the ODCM reflecting the new location(s) with information supporting the change in sampling locations.

• This requirement may be reduced according to geographical limitations; e.g. at a lake site where some sector's will be over water.

• • The nearest industrial facility shall also be documented if closer than the nearest residence.

Surveillance Requirements 12.5.2.B The Land Use Census shall be conducted during the growing season, between June 1 and October 1, at least once per 12 months using that information that will provide the best results, such as by a door-to-door survey, aerial survey, or by consulting local agriculture authorities. The results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report.

12.5.2.C This specification is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the Radiological Environmental Monitoring Program given in the ODCM are made if required by the results of this census.

This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR50. An annual garden census will not be required since the licensee will assume that there is a garden at the nearest residence in each sector for dose calculations.
