Executive Summary Executive Summary This report documents the Evacuation Time Estimate (ETE) study prepared by ARCADIS for the Byron Generating Station (BGS) in rural Ogle County, Illinois, about 4 miles south of the city of Byron, and 5 miles northeast of Oregon, IL. The study reflects the current definition of the Emergency Planning Zone, which is the region within a nominal 10-mile distance of BGS. The most recent previous study of evacuation time estimates for Byron Station was performed in 2003. The present study was performed using population data from the 2010 census.

PTV VisionTM software was used to perform evacuation modeling for different scenarios.

The PTV Vision traffic simulation software package includes VISUM (macroscopic traffic simulation) and VISSIM (microscopic traffic simulation). VISUM is a comprehensive, flexible software system for transportation planning, travel demand modeling, and network data management. VISSIM is capable of performing detailed microscopic simulation of traffic and can model any type of traffic signal control and geometric configuration.

The road network used in the evacuation simulations consists of designated evacuation routes plus any additional roadways needed to accurately simulate conditions during an evacuation. Roadway capacities were determined using NAVTEQTM digital data, updated by ARCADIS based on actual road and intersection data collected in the field in 2011.

Evacuees were generally assumed to proceed out of the Emergency Planning Zone (EPZ) via recommended evacuation routes and to make their way to designated reception centers after leaving the EPZ.

The EPZ for BGS includes parts of two counties in Illinois (Ogle and Winnebago). The resident population of the Byron EPZ is estimated at 29,241 permanent residents. Based on housing data from the 2010 U.S. Census, there are fewer than 200 estimated seasonal (summer) residents in the EPZ. The 2010 U.S. Census data at block level was used to determine population in each EPZ Sub-Area.

The transient population, which includes larger workplaces, recreational facilities, and motels, was estimated at 3,239 persons for a winter weekday and 11,393 persons for a summer weekend. The special facilities population, including nursing homes and hospitals, was estimated at 508 persons for weekday scenarios. The estimated population of schools and day care centers for a winter weekday is 6,048, including children and staff. These population estimates include intrinsic double counting, as some persons in the transient and special facility populations are also included in the permanent and seasonal resident counts. Thus, evacuation times using these population figures are considered conservative.

E-1

Executive Summary Vehicle demand for the resident population was developed based on estimated vehicle occupancy, using data obtained from a telephone survey of EPZ residents. The vehicle occupancy factor estimated from survey responses is 1.81 persons per vehicle, which represents 1.41 vehicles per household. For the 2003 study, vehicle occupancy was 2.62 persons per vehicle (one vehicle per household).

Vehicle demand for the transient population was estimated using vehicle occupancy factors ranging from 1.0 person per vehicle for the workforce population up to 3.0 persons per vehicle for some recreational areas. Vehicle demand for the school population was based on bus occupancy of 55 students. For nursing homes, vehicle occupancy is 20 persons per bus or van for residents, and two persons per ambulance for non-ambulatory patients. For nights and weekends, all facility staff would accompany patients; during weekdays, one vehicle per person was assigned for additional staff. Total vehicle demand for all population categories ranges from 17,152 (winter weeknight) to 21,527 (summer weekday).

Vehicle demand was also assigned to account for the potential shadow evacuation of the population residing immediately outside the EPZ, to a distance of 15 miles. The permanent resident population within this region is 34,491. It was assumed that 20 percent of the population in this region would evacuate. The occupancy factor for EPZ residents (1.81 persons per vehicle) was applied to estimate vehicle demand for this population. Shadow evacuees residing outside the EPZ add vehicle demand of 3,811 vehicles.

Evacuation times were estimated for evacuation of the entire EPZ for winter weekday (daytime and evening), winter weekend day, summer weekday (daytime and evening), and summer weekend cases under fair weather conditions. The weekday daytime cases were also evaluated for adverse weather conditions (snow and rain, respectively, for winter and summer).

A series of staged evacuation scenarios were also evaluated. Under a staged scenario, only the population within the 2-mile zones closest to BGS would evacuate initially; evacuation of surrounding zones would be initiated after most traffic from the 2-mile zones has cleared. The purpose of this scenario is to assess the potential reduction in evacuation times that might be achieved for the population at greatest risk.

Simulations were also performed to assess the potential impact of population growth on predicted evacuation times. This sensitivity analysis is used to define a threshold population figure that would trigger another ETE update study.

Predicted ETEs for the general population in the EPZ are summarized by scenario and distance in Table E-1 (times for 90 percent and 100 percent of vehicles to depart, for 2-mile zones, all zones to 5 miles, and all zones to 10 miles). The pattern of evacuation times is E-2

Executive Summary consistent with the differences in vehicle demand and travel time for different scenarios.

The 2-mile zone involves the shortest travel distance and the fewest vehicles; 90 percent ETEs for the 2-mile zone range from 2:25 to 3:55, and 100 percent ETEs are 4:00 to 6:20.

The times are longest for summer weekday and winter weekday scenarios with adverse weather.

For all zones out to 5 miles, the 90 percent ETEs are 2:50 to 4:10, and the 100 percent ETEs are 4:20 to 6:30. For the full EPZ, the 90 percent ETEs are 3:15 to 4:25, while the 100 percent ETEs are 5:00 to 7:20.

All of these times are indicative of significant delays related to traffic congestion. The differences in vehicle demand between scenarios are up to 30 percent of total demand, and the predicted ETEs vary by up to 50 percent. Adverse weather adds up to 85 minutes for the summer weekday ETEs, and up to 95 minutes for the winter weekday ETEs.

Exelon Generation Byron Station Evacuation Time Estimates

1. Introduction 1.1 General Evacuation time studies analyze the manner in which the population within the Plume Exposure Pathway Emergency Planning Zone (EPZ) surrounding a nuclear power plant site would evacuate during a radiological emergency. Evacuation time studies provide licensees and State and local governments with site-specific information helpful for protective action decision-making. The studies estimate the time necessary to evacuate the EPZ for a range of evacuation scenarios. Analysis of the evacuation simulation results also identifies locations where traffic management and control measures can facilitate the evacuation, and may identify unique evacuation constraints or conditions.

Estimates of the time required to evacuate from areas around nuclear power plant sites are required for all operating plants in the United States. Federal guidance has been prepared to outline the format and content of these evacuation time estimates (NUREG-0654, Rev. 1 (Nuclear Regulatory Commission (NRC), 1980), NUREG/CR-4831 (NRC, 1992) and NUREG/CR-7002 (NRC, 2011)).

Evacuation time estimate (ETE) studies were last updated for the Byron Generating Station (BGS) Plume Exposure Pathway EPZ in 2003 (Earth Tech, 2003). The guidance presented in NUREG/CR-7002 indicates that the evacuation time estimates should be updated as local conditions change, but at least once each decade, following release of the federal census. The current update study was prompted by the issuance of revised ETE guidance (CR-7002) and the availability of population data from the 2010 census.

Census data indicate that the population residing within the EPZ for BGS increased by 2,145 between 2000 and 2010, which represents a 7.9 percent population increase.

(Population data are discussed further below in section 1.4.)

The evacuation time estimates have been developed using current population, local roadway network characteristics and the PTV VisionTM traffic simulation software package to perform evacuation modeling for different scenarios. PTV Vision includes the VISSIM (microscopic traffic simulation) and VISUM (macroscopic traffic simulation) models.

Evacuation times have been estimated for various areas, times and weather conditions, as outlined in CR-7002. These evacuation times represent the times required for completing the following actions:

• Public notification; 1-1

Exelon Generation Byron Station Evacuation Time Estimates

• Preparation and mobilization; and

• Actual movement out of the EPZ (i.e., on-road travel time, including delays associated with vehicle queuing).

1.2 Site Location and Emergency Planning Zone (EPZ)

This report describes the analyses undertaken, and the results obtained, in a study to update the existing Evacuation Time Estimates for BGS. The emergency response plan is designed to protect the health and safety of the public in the event that an evacuation is ordered as a protective action in response to an accident at BGS.

BGS is located in Rockvale Township, Ogle County, IL, about 4 miles south of Byron, IL and 15 miles southwest of Rockford, IL. The plant location is shown in Figure 1-1.

The plume exposure pathway emergency planning zone (EPZ) is the geographic area surrounding a nuclear power plant within which the NRC requires advance planning for evacuation or other short-term protective actions in the event of a radiological emergency.

The Byron Station EPZ consists of the area within an approximate 10-mile radius of BGS.

The EPZ includes part of two counties (Ogle and Winnebago). The Byron Station EPZ is subdivided into a total of 12 Sub-Areas, or Emergency Response Protection Areas (ERPAs). These ERPAs are the basic units for which protective action recommendations are issued. Sub-Area boundaries often follow geographic (township) boundaries, and reflect distance and direction from BGS. The distance ranges of concern are 0-2 miles, 2-5 miles, and beyond 5 miles. EPZ and ERPA boundaries are shown in Figure 1-1.

Most of the EPZ area is in Ogle County. Only ERPAs 39 and 40, on the north side of the EPZ, are in Winnebago County. Each of the ERPAs in Ogle County is an entire township.

The ERPAs are described in more detail in Section 3.

A listing of the 2010 permanent resident population by ERPA within the Byron Station EPZ is shown in Figure 1-1. Table 1-1 compares the EPZ population from the 2010 and the 2000 census. The EPZ population of 29,241 residents is concentrated in several villages and small cities (Byron, Oregon, Mount Morris, and Davis Junction). ERPA 17, which includes the city of Byron, has the largest population (6,563). Five ERPAs each contain more than 10 percent of the resident population.

The population residing in the EPZ grew by 2,145 between 2000 and 2010, an increase of 7.9 percent. ERPA 27 gained 1,510 residents, an increase of 90 percent. ERPAs 17 1-2

Exelon Generation Byron Station Evacuation Time Estimates and 23 each grew by 12 percent. The rest of the EPZ experienced a small net loss, with small gains or losses in individual ERPAs.

The Rock River crosses the EPZ from southwest to northeast, generally parallel to Highway 2. The area within 2 miles of BGS is rural in character. ERPA 19, which contains BGS, has 1,770 residents; most of those live near Byron, about 4 miles from the plant.

NRC guidance also requires consideration of potential shadow evacuation of the population residing immediately outside the EPZ, to a distance of 15 miles. The permanent resident population in the region surrounding the EPZ within 15 miles of BGS is 34,491. Most of this population resides in the city of Rockford, IL (pop. 152,871),

located northeast of BGS in Winnebago County. Shadow evacuees residing outside the EPZ add vehicle demand of 3,811 vehicles. A map showing the population by distance and direction sector within 15 miles of Byron Station is provided in Figure 1-2. (Due to roundoff errors that propagate when sector boundaries cut across census block boundaries, the population numbers disagree slightly between Figure 1-1 and Figure 1-2.)

1.3 Designated Reception Centers The Byron Station emergency response evacuation plan directs residents of communities within the EPZ to evacuate to specified reception centers. If evacuation is initiated while schools are in session, students will be transported directly to designated Host Schools, and families are instructed to meet up with the students at those locations.

The designated receiving communities for ERPAs within the Byron Station EPZ are Rockford, Freeport and Dixon, IL. The preferred reception community for each ERPA is listed in Table 1-2. (Some ERPAs may evacuate differently, depending upon the prevailing wind direction.) The roadway network used to develop evacuation time estimates includes the major roadways recommended to the public as evacuation routes from individual communities to designated reception centers. The roadway network is designed to utilize all available major roadways, with traffic flow directed radially outward from BGS toward the EPZ boundaries. The roadway network is described in detail in Section 4.

1.4 Overview of Changes from Previous ETE Study The changes in residential population within the EPZ are summarized in Table 1-1. The revised NRC guidance and newly acquired data led to a number of other changes in the 1-3

Exelon Generation Byron Station Evacuation Time Estimates ETE methodology and assumptions. Table 1-3 provides a summary comparing the main features and assumptions of the current study to the 2003 ETE study. The telephone survey of EPZ residents provides a new basis for estimating vehicle occupancy and departure times, while new NRC guidance has specified different assumptions regarding background and shadow traffic. The ETE methodology and assumptions for the current study are discussed in greater detail in following sections of the report.

The revised vehicle occupancy for residents (1.81 persons per vehicle, based on survey),

revised departure times for schools and special facilities (no early warning) and the revised departure time curves for residents (based on survey responses and estimated time for warning diffusion) are expected to have the greatest influence on estimated evacuation times. The shadow evacuation adds vehicle demand of 3,811 vehicles in the area immediately outside the EPZ. The potential impacts of shadow evacuation will be greatest for travel to the Rockford reception center. Each of these issues is discussed in more detail in following sections of the report.

Exelon Generation Byron Station Evacuation Time Estimates

2. Methodology and Assumptions 2.1 Sources of Data and General Assumptions The following data sources were reviewed and assumptions made in order to develop the appropriate population and roadway databases used for the evacuation analysis:

• Population estimates for permanent residents were developed from 2010 U.S.

Census Bureau data.

• Population estimates for seasonal residents were developed from 2010 United States Census Bureau data on housing units. Census data identify the number of seasonal housing units (vacant housing units for seasonal or occasional use) at different geographic levels (e.g., by township, census tract, block group, block). A conservative estimate of seasonal population was developed by assigning six persons per seasonal housing unit.

• Population estimates for major employers were developed from ESRI list and the facility list from the 2003 study report. ARCADIS conducted internet searches and telephone surveys to estimate facility employment and staffing levels for different scenarios. Only facilities with potential staffing level of at least 50 persons per work shift were pursued.

• Information relating to hotels, motels and recreational facilities was obtained from tourism websites, 2011 AAA TourBook listings, and the 2003 study report. For parks, visitation information was obtained from state park agencies.

• Current population estimates for schools were obtained primarily from county emergency response agencies, plus enrollment information available on the internet.

• Lists of hospitals, rest homes and incarceration facilities were obtained from each county emergency management agency.

• The staffing levels at BGS reflect estimated peak personnel onsite during outage conditions. These data were provided by Exelon Generation.

2-1

Exelon Generation Byron Station Evacuation Time Estimates

• Initial estimates of roadway characteristics were obtained from the NAVTEQ database. Roadway geometric and operational data were compiled based on field surveys performed by ARCADIS in 2011.

• Average traffic volumes by time of day for weekday and weekend for designated evacuation routes were obtained from state and county transportation agencies.

These data were used to assign background traffic volumes for the roadway network. It was assumed that access control would be established within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> following the public notice to evacuate.

• Preparation and mobilization times for the permanent resident population were developed based on the results of a telephone survey, combined with published time estimates for warning diffusion. The survey provided estimates of the time to depart from home following notification, and commuting times for household members who would return from work before departing. Median departure times for residents are longer than the times assumed in the previous study.

• Departure times for transient facilities were estimated assuming relatively prompt evacuation of most workplaces and recreational facilities once notification is received. The distribution of departure times also reflects information gathered from the telephone survey of EPZ residents, as discussed in Section 3.

• The evacuation time estimates represent the time required to evacuate the Byron Station EPZ and designated analysis areas and include the time required for initial notification.

• Evacuation time estimates are presented for 90 percent and 100 percent of evacuating vehicles. It is assumed that all persons within the EPZ area will evacuate. For the 100 percent evacuation time, evacuation of the EPZ will be considered complete after all evacuating vehicles are outside of the EPZ or analysis area.

• The general public will evacuate using designated evacuation routes and will proceed to the reception centers listed in Table 1-2 after leaving the EPZ. When schools are in session, children attending school will be transported directly to designated Host Schools.

• It is assumed that existing lane utilization will prevail during the course of the evacuation. Traffic control signals will be over-ridden or converted to flashing 2-2

Exelon Generation Byron Station Evacuation Time Estimates mode as necessary to give preference to flow on all major outbound roadways. It is also assumed that State and municipal personnel will restrict unauthorized access into the EPZ, consistent with existing traffic management plans.

• The evacuation analysis cases are described in Section 2.3 and represent a range of conditions, per guidance presented in CR-7002. These cases have been chosen to provide information for an appropriate range of conditions (i.e., low, typical and high population; fair and adverse weather) to guide the protective action decision-making process. Potential special events such as holiday parades and sporting events occurring within the EPZ were considered, based on input from state and county agencies. None of these events was judged to represent a major departure from the peak traffic assumptions reflected in the standard scenarios, so a Special Event scenario was not included in this study.

• Vehicle occupancy rates used for the various population categories are as follows:

- Permanent residents: 1.86 persons per vehicle, based on telephone survey results

- Major places of employment - 1 vehicle per employee.

- Motels - 1 vehicle (1 to 2 persons) per occupied room.

- Recreational areas - 1 vehicle (3 persons) per campsite; 1.5 persons per vehicle at visitor centers and museums.

- Schools: 55 students and 3 staff per bus; one vehicle per additional staff person.

- Hospitals/Nursing Homes/Correctional Facilities - 2 persons per ambulance/

medical van for non-ambulatory patients and 20 people per bus or van for ambulatory residents.

• The transport-dependent population will be evacuated by bus or ambulance through efforts coordinated by state and municipal emergency preparedness officials.

2-3

Exelon Generation Byron Station Evacuation Time Estimates

• Adverse weather refers to moderate to heavy rainstorms for summer conditions, and a moderate snowstorm for winter conditions.

2.2 Interaction with Agencies Emergency management agencies responsible for planning and implementing the emergency response procedures during a radiological emergency were consulted during the development of this ETE study. The Illinois Emergency Management Agency (IEMA) and emergency agencies for Ogle and Winnebago Counties were contacted to obtain information regarding special and transient facilities in the EPZ, transportation resources available to evacuate special facilities, and the transport dependent general public. Those agencies were also consulted to identify any major events that take place within the EPZ that should be considered for a Special Event scenario The Illinois Parks and Recreation Association (IPRA) list of special and transient facilities for all six Exelon nuclear stations in Illinois was provided to ARCADIS by Exelon. IEMA and the county agencies reviewed the draft report and the facility databases used in this study.

Representative background traffic volumes for the EPZ roadway network were obtained from state and county transportation agencies.

2.3 Summary of Methodology for Traffic Simulation The evacuation time estimates developed for the Byron Station EPZ are based upon a time distribution of evacuation events as opposed to a summation of sequential events.

This methodology assumes that the various time components in an evacuation (i.e.,

the time associated with preparation, mobilization, etc.) overlap and occur within certain time ranges. The time distribution approach is based upon assumptions consistent with the NRC guidance of CR-7002.

Trip generation times are used to develop vehicle loading curves for different population types within the permanent, transient, and special facility populations. A trip generation time consists of two main components: warning diffusion time and mobilization time. Warning diffusion time is the time it takes for people to receive an emergency notification. The type of warning systems employed in the EPZ, such as emergency alert system (EAS), sirens, and tone alert radios (TARs) affects the distribution of warning times. Availability of more warning systems leads to faster warning diffusion to the public.

2-4

Exelon Generation Byron Station Evacuation Time Estimates Mobilization time is the time between the receipt of notification and when individuals leave for evacuation. Mobilization time depends on the type of population and activity.

Warning diffusion time and mobilization time distributions are used to develop composite loading distribution or trip generation curves for different population segments. Trip generation times for transit dependent facilities, special facilities and schools were developed separately from those for the general public.

2.4 Conditions Modeled Pursuant to the guidance in CR-7002 and NUREG-0654, Rev. 1, evacuation time estimates have been prepared for a range of temporal, seasonal and weather conditions. Estimates have been prepared for weekday, weeknight and weekend scenarios during winter and summer. All scenarios are simulated with fair weather conditions; weekday scenarios are also simulated assuming adverse weather. Fair weather refers to conditions where roadways are clear and dry, and visibility is not impaired. Adverse weather during summer periods is defined as heavy rain, with impaired visibility; roadway capacities are reduced by 10 percent and speeds are reduced by 15 percent. Adverse weather during winter periods is defined as a snowstorm condition where roadway capacities and speeds are reduced by 15 percent.

The various population components which have been incorporated in the evacuation scenarios are summarized below:

2.4.1 Week Day This situation represents a typical weekday period with the work force is at a full daytime level. During winter, schools are in session. Vehicle demand estimates for weekday scenarios reflect the following conditions:

• Most permanent residents within the EPZ will evacuate from their places of residence;

• Major work places are fully staffed at typical daytime levels;

• BGS employment is at an estimated peak daytime level, representative of operation during outage conditions;

• Schools and daycares are at current enrollment; 2-5

Exelon Generation Byron Station Evacuation Time Estimates

• Hospitals and nursing homes are at current enrollment or typical occupancy;

• Motel facilities are occupied at peak (winter or summer) levels; and

• Recreational facilities are at winter or summer weekday levels.

2.4.2 Week Night This situation reflects a typical night period when most permanent residents are home and the work force is at evening shift level. Assumptions on the population levels for this condition include the following:

• Permanent residents within the EPZ will evacuate from their places of residence;

• Major work places are at typical evening levels;

• BGS employment is at an estimated peak night-time level;

• Day schools and daycares are closed;

• Hospitals and nursing homes are at current enrollment or typical occupancy, and staffing is at typical night-time levels;

• Motel facilities are occupied at (winter or summer) weekday levels; and

• Recreational facilities are at typical (winter or summer) evening levels.

2.4.3 Weekend The weekend scenario represents a daytime period when most residents are at home and major work places are at typical weekend levels. Assumptions on the population levels for this condition include the following:

• Residents within the EPZ will evacuate from their places of residence;

• Major work places are at typical weekend levels;

• Day schools and daycares are closed; 2-6

Exelon Generation Byron Station Evacuation Time Estimates

• Hospitals and nursing homes are occupied and staffed at weekend levels;

• Motel facilities are occupied at weekend (winter or summer) levels; and

• Recreational facilities are at (winter or summer) weekend levels.

2.4.4 Special Event Consideration County agencies and IEMA were asked to identify events such as a county fair or Fourth of July observance that would bring a large number of visitors into the EPZ. No events were identified that are large enough to pose a significant challenge for an emergency evacuation, so a Special Event scenario was not developed for the Byron EPZ. (The same decision was made for the 2003 update study.)

2.4.5 Sensitivity to Population Growth and Roadway Impact Additional scenarios were evaluated to assess the sensitivity of ETEs to population growth and roadway impact. These sensitivity cases used the Summer Weekday, Normal Weather case for the Full EPZ as the base case. The population growth analysis is used to determine how rapidly the ETE would increase as the resident population in the EPZ is increased.

For the roadway impact scenario, a major evacuation route is removed or reduced in capacity. Specifically, one of the five highest volume roadways is removed from service, or capacity is reduced by one lane (for a multi-lane, limited-access roadway such as an interstate highway). A more detailed description of the sensitivity analysis is provided in Section 6.5.

3. Population and Vehicle Demand Estimation The development of vehicle demand estimates for the Byron Station EPZ consisted of two primary steps. The first step was the determination of the number and distribution of the population to be evacuated. The second step was the determination of the appropriate number of vehicles for each of the population categories. Federal guidance (CR-7002) indicates that three population categories should be considered:

permanent residents, transients, and persons in schools and special facilities (such as medical facilities/ nursing homes, and day care facilities).

The methodology used to develop the total population and vehicle demand estimates within the Byron Station EPZ incorporates intrinsic double counting. For example, a portion of the identified employees and visitors to recreational areas are also permanent residents within the EPZ. In addition, school children are counted in the resident population, but are also counted in the special facility population. While population and vehicle demand estimates incorporate some adjustments for double-counting, the estimates are considered to be conservative (i.e., they over-estimate actual population and vehicle levels which may be in the area at any given time).

Population and vehicle demand estimates for each of the population categories are summarized below.

3.1 Permanent Residents Permanent residents are those persons identified by the census as having a permanent residence within the EPZ. The Census 2010 population data for census tracts, block groups and blocks were used to determine the permanent resident population within the EPZ and within each municipality and Sub-Area. The allocation of the resident population to entry nodes on the roadway network was based on detailed census block maps.

An estimated 29,241 persons reside permanently within the Byron Station EPZ.

Table 3-1 presents the resident population and vehicle demand by Sub-Area. The EPZ Sub-Areas are defined based on distance and direction from BGS, and generally follow geographic (township) boundaries. ERPA 19 (Rockvale Township) contains BGS. This ERPA extends 6 miles west of BGS and 3 miles north and south. ERPA 23 (Marion Township extends 6 miles to the east, 3 miles to the south, and almost 10 miles northeast of BGS. The village of Stillman Valley is in ERPA 23. ERPA 17 (Byron Township) extends from 3 miles north to 9 miles north of BGS. ERPA 17 contains the city of Byron and has the largest resident population in the EPZ. ERPA 20 (Oregon-Nashua Township) extends from 3 miles to 10 miles SSW of BGS. ERPA 20 contains 3-1

Exelon Generation Byron Station Evacuation Time Estimates the city of Oregon. ERPA 25 and ERPA 28 extend to 10 miles southeast of BGS.

ERPA 27 contains Davis Junction and extends from 6 miles to 10 miles east of BGS.

On the western side of the EPZ, ERPAs 10, 12 and 14 extend to 10 miles distance.

The city of Mount Morris is in ERPA 12, and the village of Leaf River is in ERPA 10.

On the north side of the EPZ, ERPAs 39 and 40 in Winnebago County extend from 8 to 10 miles distance from BGS.

A telephone survey of EPZ residents was conducted to obtain information relating to how many vehicles residents would use to evacuate and how long it would take them to depart following notification. The survey questionnaire and results are provided in Appendix B.

3.1.1 Auto-Owning Permanent Population Vehicle demand associated with the permanent resident population was estimated based on telephone survey responses. After adjusting survey results to reflect the age distribution of the EPZ, the estimated occupancy factor is 1.81 persons per vehicle, which corresponds to 1.41 vehicles per household. Total vehicle demand for EPZ residents for all scenarios is 16,155. Shadow evacuation of 20 percent of the population residing outside the EPZ within 15 miles of BGS adds vehicle demand of another 3,811 vehicles.

For the 2003 ETE study, evacuation times were determined for vehicle demand assumption of one vehicle per household, or 2.62 persons per vehicle, for permanent residents.

3.1.2 Transport-Dependent Permanent Population Emergency response plans specify that the transport-dependent population will receive transportation assistance. The Ogle County Emergency Response Plan includes provisions for providing this assistance, including bus routes with designated pickup points in Byron, Oregon and Mount Morris. Based on telephone survey results, about 2 percent of households (with phones) had either no vehicle or no licensed driver. NRC guidance (CR-7002) indicates that between 1.5 and 5 percent of residents may require transportation. ETE estimates are based on evacuation of up to 480 transit dependent residents.

3-2

Exelon Generation Byron Station Evacuation Time Estimates Individuals requiring transit from reception centers to congregate care centers will be transported in a separate set of vehicles from those designated to transport the transit dependent and special facilities out of the EPZ.

3.2 Seasonal Residents The seasonal population category addresses those who reside in the EPZ on a temporary basis, particularly during the summer period. The 2010 U.S. Census of Population and Housing reports the number of vacant households classified as for seasonal or occasional use. Census data identified less than 50 such housing units in the Byron Station EPZ, and less than 10 in any ERPA. These low numbers indicate that the number of seasonal residents in the Byron EPZ is not significant, relative to the permanent resident population.

3.3 Transient Population The transient population segment includes persons in the work force, hotels/motels, and recreational areas. Regional maps and mapping software were used to determine facility locations and assign entry nodes. Significant employers within the EPZ were identified using ESRI Business Analyst Online (BAO). BAO is a web-based analytical and mapping tool that facilitates location-specific queries about business and demographic data. Data available on BAO includes information on business location and number of employees. ESRI extracts business data from a comprehensive list of businesses (over 12 million U.S. businesses) licensed from Infogroup. ARCADIS used BAO to search for all employers with 50 or more employees located within an 11-mile radius of BGS. CR-7002 recommends consideration of large employers with 50 or more employees on a single shift.

The list from BAO was screened to eliminate businesses where workers do not remain on-site (e.g., transportation and trucking companies, construction, realtors, home health care). Employment at schools and special facilities (e.g., hospitals, nursing homes) is generally tracked as part of the special facilities database. The reduced list was then reviewed to exclude facilities located outside the EPZ, and to determine the ERPA for those located in the EPZ. The new list of employers was compared to the list from the 2003 study and the IPRA Special Facilities list provided by IEMA.

Telephone calls were made to selected large employers to verify employment numbers and to estimate staffing levels during weekday, weeknight and weekend periods. The results from those calls confirmed that BAO listings provided accurate locations and current, reliable employment numbers for most establishments. Workforce numbers for 3-3

Exelon Generation Byron Station Evacuation Time Estimates BGS were provided by Exelon Generation and reflect the peak work force during outage conditions.

Numbers of units and campsites for motels and recreational areas were obtained from the TripAdvisor website, the 2011 AAA TourBook for Illinois, and from state and county tourism websites. Seasonal occupancy was estimated based on capacity figures (e.g.,

number of campsites) and a telephone survey of selected facilities. State and local parks agencies also provided visitation numbers for parks and campgrounds.

For purposes of estimating the total number of vehicles associated with the transient population segment, an occupancy factor of 1.0 employee per vehicle was used for most work places. For the hotel/motel and recreational populations, it was assumed that there would be 1.0 vehicle (1.5 or 2 persons) per hotel/motel unit, and 1.0 vehicle (3 to 4 persons) per campsite. For parks, visitation numbers were generally obtained as numbers of vehicles, and an occupancy factor of 3.0 persons per vehicle was assumed. For museums and visitor centers, 1.5 persons per vehicle was assumed.

Campgrounds were assumed to be fully occupied during summer. Motels were assumed to be fully occupied for all scenarios.

Vehicle demand was reduced for selected recreation facilities in consideration of double-counting. Local residents represent a substantial portion of attendance at these facilities, and it was assumed that many residents would return home before evacuating the EPZ.

Table 3-2 presents a summary of the transient population by Sub-Area for each scenario. The transient population and associated vehicle demand are greatest for summer weekday and summer weekend scenarios. Recreation facilities are located primarily along the Rock River (ERPA 17, 19, 20, 23) and in ERPA 14. For the summer weekday scenario, the two ERPAs with highest population and vehicle demand from transient facilities are 12 and 19, reflecting a combination of employers and recreation facilities. For the summer weekend scenario, the two ERPAs with highest population and vehicle demand are 14 and 23, reflecting the dominant impact of recreation facilities. Population data and vehicle demand estimates for the transient population segment, including the work force, hotels and motels, and recreational areas are presented by facility in Appendix A. A breakdown of population by distance and direction sectors was not developed for transient and special facilities, since state and county agencies rely on population by ERPAs for emergency response planning.

3-4

Exelon Generation Byron Station Evacuation Time Estimates 3.4 Special Facilities Population The special facility population segment includes persons in schools, hospitals, nursing homes and correctional facilities who will require transportation assistance during an evacuation. Most of these facilities are located in ERPAs with cities (12, 17, 20, 23).

The special facilities population is summarized by ERPA in Table 3-3; data by facility is provided in Appendix A.

3.4.1 Medical, Nursing Care and Correctional Facilities One healthcare center, two nursing homes and two assisted living facilities are located in the EPZ. Vehicle occupancy for nursing home patients is two non-ambulatory patients and one staff per ambulance, 20 residents or patients plus 3 staff per vehicle (bus or van) for ambulatory patients, plus one vehicle per staff person who does not evacuate with patients.

3.4.2 Schools and Day Care Thirteen public schools and six pre-school/daycare facilities have been identified within the Byron Station EPZ, with a total population of 5,948 students and staff. None of the identified schools is residential, so students are only present on weekdays during the school year. Vehicle occupancy for public schools is based on 58 persons (55 students, 3 staff) per bus, plus one vehicle per additional school staff. Student population for public schools was determined from state-published enrollment information.

Six licensed child care (large daycare) facilities were identified in the EPZ, with an estimated daytime population of 252. Facilities were identified from internet listing of licensed childcare establishments. The population estimates represent the licensed capacity of each facility. Smaller home-based daycare facilities (capacity 10 or less) were not tabulated; those facilities contribute little vehicle demand beyond that assigned to EPZ residents.

3.5 Emergency Response Planning Area Population Totals Population and vehicle demand totals for each Sub-Area are summarized in Table 3-4.

The totals listed in the table represent the peak number of people to be evacuated for each analysis case discussed in Section 6 of this report.

3-5

Exelon Generation Byron Station Evacuation Time Estimates Vehicle demand is highest for the summer weekday scenario. Vehicle demand for the highest (summer weekday) scenario is almost 30 percent higher than the lowest (winter weekend) scenario. ERPA 17, which includes the city of Byron, has the largest population and vehicle demand for all scenarios. The vehicle demand listed in Tables 3-2, 3-3 and 3-4 reflects the data used as input for the ETE traffic simulations.

Exelon Generation Byron Station Evacuation Time Estimates

4. Evacuation Roadway Network 4.1 Network Definition In order to estimate evacuation times for the Byron Station EPZ, an evaluation of the roadway network likely to be used by departing vehicles was undertaken. ARCADIS relied on several sources of information to define the evacuation roadway network:

• Evacuation routes described in the existing State emergency response plan;

• Maps of highways and local roadways for the EPZ area;

• A field survey of the roadways in the Byron Station EPZ.

The primary evacuation routings used in the modeling are indicated in Figure 4.1.

4.2 Evacuation Route Descriptions The evacuation routings were developed to simulate travel out of the EPZ using available roadways. The network relies primarily on the evacuation routings depicted in the public information brochure. Descriptions of the primary evacuation routes for different geographic areas within the EPZ are outlined in Table 4-1.

4.3 Characterizing the Evacuation Network Roadway characteristics such as roadway class, number of lanes, lane and shoulder width, speed limit, lane configuration near intersections, and traffic control are key factors in determining how fast an evacuation can be completed. These roadway attributes control roadway capacity, which in turn governs operating traffic conditions measured in terms of level-of-service (LOS). LOS is measured from A to F for roadway segments and intersections. LOS A represents free-flow conditions, and LOS F represents force or breakdown flow conditions.

ARCADIS used NAVTEQTM roadway data with detailed information, including local streets, to build the evacuation roadway network for the study. NAVTEQ data was imported into geographic information system (GIS) software (ESRI ArcGISTM) for conducting field surveys to verify evacuation roadway segment attributes. The information provided in the public information brochure for the site was used to highlight evacuation routes in GIS. ARCADIS has developed an integrated GIS-Global 4-1

Exelon Generation Byron Station Evacuation Time Estimates Positioning System (GPS) tool that allows field personnel to record observations in an efficient and effective manner. The evacuation network, including traffic controls, was verified to a 15-mile radius from the plant, and along designated routes to the receptions centers. Once the NAVTEQ data was verified through the field survey, the evacuation roadway network was transferred to the traffic simulation software VISUM for modeling different evacuation scenarios.

Having accurate traffic control information is important to accurately estimate evacuation times because intersections have potential to create bottleneck points.

During an evacuation scenario, intersections might be manually controlled by officials, operated with existing traffic signal timing plans, or adjusted according to changing vehicular demand.. In general, the emergency response plans for Byron Station call for signal override, i.e., signals set to flashing to give priority to outbound travel on designated evacuation routes. Traffic control information is coded as part of the evacuation network database.

Background and pass-through traffic in the EPZ could account for significant number of vehicles and could influence evacuation depending on the direction of travel. As recommended in CR-7002, average daily traffic (ADT) volumes, representative of typical background levels, were obtained from state and county transportation agencies. During the simulations, background traffic will be included during the initial 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of the evacuation scenario, up to the time when access control is established to prevent vehicles from entering the EPZ.

A map of the evacuation network showing node numbers and links, as recommended by the latest guidance, is provided in Appendix C. Detailed attributes of each roadway segment, such as link number, number of lanes, speed limit, length, and roadway type are also tabulated in Appendix C.

5. Evacuation Time Estimate Methodology 5.1 Evacuation Analysis Cases Time estimates have been prepared for a general evacuation scenario for each of these analysis cases:

• Winter Weekday, Fair Weather and Adverse Weather Conditions

• Winter Weeknight, Fair Weather Conditions

• Winter Weekend, Fair Weather Conditions

• Summer Weekday, Fair Weather and Adverse Weather Conditions

• Summer Weeknight, Fair Weather Conditions

• Summer Weekend, Fair Weather Conditions Areas for evacuation are selected based on the keyhole configuration (0-2 mile zone plus 2-5 mile or 0-5 mile plus 5-10 mile downwind zone). The partial-EPZ evacuation areas for BGS are reproduced in Table 5-1, based on the Protective Action Recommendation (PAR) chart. Separate simulations may not be necessary for each of the areas listed in Table 5-1. ETE estimates will generally be controlled by whether one or two critical Sub-Areas (e.g., ERPA 7) are included. Enough cases will be run to ensure that representative ETE estimates are obtained for all potential scenarios.

For all partial-EPZ evacuation cases, shadow vehicle demand (20 percent of residents) is assigned to all Sub-Areas which are not included in the evacuation region, in addition to the region outside of the EPZ.

This system will be used by state and local officials to alert the population to turn on their radios and television sets. Pursuant to NUREG 0654, Rev. 1 guidance, notification messages will commence on the designated television and Emergency Alert System (EAS) radio stations concurrent with sounding of the sirens. Within 15 minutes of alert notification, essentially all of the population within the EPZ will begin to receive an informational or instructional message. If evacuation is deemed necessary, the timing of the order to evacuate and notification measures will be controlled by the state and local emergency preparedness officials. Those officials may choose to alert and mobilize an emergency response work force to control and expedite evacuation prior to the evacuation order.

5-2

Exelon Generation Byron Station Evacuation Time Estimates 5.3 Transportation Dependent Population The transportation dependent population includes individuals without access to transportation, as well as those requiring special transportation assistance.

Transportation dependent persons will be notified of a protective action recommendation in the same manner as the general public. If evacuation is recommended, persons needing transportation assistance will be informed through the EAS to contact the appropriate officials for assistance. Evacuees who do not have access to transportation and confined persons who require special transportation assistance will be provided transportation by the appropriate agency.

5.4 Evacuation Preparation Times and Departure Distributions It is assumed that no vehicles will begin to evacuate during the 15-minute initial notification period. Accordingly, in the model simulations, vehicles will begin to evacuate at 15 minutes following the initial notification. After the initial 15-minute time period, vehicles are loaded at a linear rate over each 5-minute time interval, in accordance with the network loading distributions for each population type. For example, if 2 percent of 2500 vehicles (50 vehicles) are to be loaded at a specific location over a 5-minute period, PTV Vision will load 10 vehicles per minute at that location during the specified interval. Network loading distribution assumptions for the permanent population, transient population, and special facilities are based on the anticipated response of different population sectors to an evacuation order.

Mobilization times for residents and workers reflect the data acquired by the telephone survey of EPZ residents, and are consistent with published data from actual historical events (ORNL, 1990). Loading distributions are explained below, and summarized in Figure 5-1.

5.4.1 Permanent and Seasonal Population Permanent and seasonal residents with access to automobiles will take varying amounts of time to begin evacuating. Some persons will leave as quickly as possible; most will take some time to prepare, pack valuables and clothes and then depart; some will take added time to secure property before departing; and some may require transportation assistance. In addition, actual departure and preparation times may vary according to the perceived severity of a particular evacuation order.

Based upon these factors, it was assumed that there would be a period of up to 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> over which the permanent residents would begin to evacuate. That is, permanent 5-3

Exelon Generation Byron Station Evacuation Time Estimates resident households would begin to evacuate between 15 and 180 minutes after the decision to notify the population to evacuate is made. Based on estimated warning diffusion and survey results from EPZ residents, during a weekday, 50 percent would depart within 75 minutes, 90 percent within 110 minutes, and 99 percent within 180 minutes. At night, with most household members at home, 50 percent would depart within 60 minutes, 90 percent within 95 minutes, and 99 percent within 165 minutes.

These time profiles are generally consistent with observed behavior during evacuations for chemical releases.

5.4.2 Transient Population It was assumed that the work force would be subject to the same warning diffusion as the general public. Based on estimated warning diffusion and survey results from EPZ residents, it was estimated that 50 percent of the work force would evacuate within 40 minutes following the decision to evacuate, 90 percent within 65 minutes, and 99 percent within 105 minutes. For a few facilities, it may be necessary for a limited number of workers to remain on the job in order to safely shut down processes, secure the facility or maintain essential operations. The evacuation time estimates do not address those workers who remain behind, since there is no reliable basis for predicting whether or how soon they will evacuate. The assumption that all workers evacuate provides a conservative estimate of vehicle demand. Discussions with emergency preparedness officials indicate that the same time distribution is also reasonable for the other transient population categories within the EPZ, including motels and recreation areas.

5.4.3 Special Facilities It was assumed that special facilities (i.e., schools, nursing homes) within the EPZ would also receive initial notification promptly. Based upon data obtained from previous studies, vehicle departure times were developed that reflect a distribution of notification, preparation and mobilization times.

Consistent with the current off-site emergency response plans, it was assumed that schools will be evacuated via bus to the designated host schools. For school facilities, it was assumed that up to 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> may be required to assemble buses, transport vehicles to schools and to load students onto buses. Vehicles stationed at the facilities at the time of the ordered evacuation could be loaded in as little as 15 minutes following notification. Accordingly, 50 percent of school buses depart onto the evacuation network during the period between 15 and 75 minutes, 90 percent by 135 5-4

Exelon Generation Byron Station Evacuation Time Estimates minutes, and 99 percent by 180 minutes. The school profile was also applied for daycare facilities.

Evacuation of nursing home facilities would also require additional time associated with preparation and transport of vehicles to the respective facilities. Based upon previous studies, it was assumed that these facilities would begin to evacuate between 30 minutes and 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> following notification. The first 50 percent will depart within 90 minutes, 90 percent within 150 minutes, and 99 percent within 165 minutes.

Exelon Generation Byron Station Evacuation Time Estimates 5.5 Evacuation Simulation Traffic simulation provides the ability to analyze evacuation of an area in great detail. In most traffic simulation models, there are two main inputs: supply (roadway) network data and demand (population and vehicular) data. Traffic models use different types of algorithms to predict traffic flow and provide measures of effectiveness (MOEs) such as average travel times, total number of vehicles exiting the system, and queue lengths at various times and points.

5.5.1 General Structure ARCADIS used PTV Vision to perform evacuation modeling for different scenarios.

The PTV Vision traffic simulation software package includes VISSIM (microscopic traffic simulation) and VISUM (macroscopic traffic simulation). VISUM is a comprehensive, flexible software system for transportation planning, travel demand modeling, and network data management. VISSIM is capable of performing detailed microscopic simulation of traffic, public transport, and pedestrian simulations, and can model any type of traffic control and geometric configuration. Both VISUM and VISSIM are capable of performing multi-modal analysis including car, commercial vehicle, bus, train, motorcycles, bicycles, and pedestrians. The two programs work together seamlessly, saving valuable time and resources.

Figure 5-2. Evacuation Modeling and Simulation using PTV Vision Suite 5-6

Exelon Generation Byron Station Evacuation Time Estimates VISUM was used to develop the evacuation network and population entry nodes (centroids). One of the key features of VISUM is its ability to interact seamlessly with GIS-data such as ESRI ArcGIS database. The field verified evacuation network data and demand data developed in ArcGIS were imported directly into VISUM. Origin-Destination trip tables were developed for the evacuation and imported into VISUM.

VISUM software was then used to route the Origin-Destination information on the network using a dynamic equilibrium algorithm. This algorithm ensured that traffic levels on the network were realistic given the capacities available on individual links.

Once an initial solution was found in VISUM, the information was exported into VISSIM for microsimulation. A microsimulation was deemed a necessary step in order to obtain detailed and realistic results on queuing and average travel times. VISSIM can model intersection with different type of traffic control such as yield signs, stop signs, and signals. VISSIM also provides a better understating of critical and congested part of the network.

5.5.2 Simulation Process The ETE results include the time to evacuate 90 percent and 100 percent of the total permanent and transient population. Based on the current guidance, ETEs for special facilities, schools, and the transit dependent population are developed separately; only the time to evacuate 100 percent of these population groups was needed.

Consistent with current guidance, vehicle demand for each scenario was based on 100 percent of the population residing in areas designated for evacuation, plus 20 percent of the population residing in Sub-Areas outside the designated evacuation area, and 20 percent of the population residing outside of the EPZ, out to a distance of 15 miles.

Vehicle demand outside of the designated evacuation area is intended to account for the impact of shadow evacuees. A sensitivity analysis was performed to evaluate the impact of changes different input parameters and assumptions such as changes in lane closures, trip generation times, vehicular demand, evacuation routes, and background traffic.

The simulation process can be summarized as follows:

VISUM

1. Create every scenario based on

a. Background traffic

b. Time of day 5-7

Exelon Generation Byron Station Evacuation Time Estimates

c. Day of week

d. Weather condition

e. Season

f. Wind Direction

g. Shadow traffic

2. Run Dynamic Traffic Assign to and calculate Permanent and Transient, Shadow, Special Needs/Schools volumes

3. Assignment process will last until suitable convergence is reached. VISUM provides output on the goodness of convergence after assignment. The convergence fit is not as critical because this is an evacuation model of a no-notice event, therefore full user equilibrium cannot be expected.

4. Export to VISSIM.

VISSIM

1. Warm-up time built into background/pass-through traffic generation.

2. Check for any local calibration parameters.

3. Run the final multimodal Dynamic Traffic Assignment in VISSIM to consider queues and intersection delays

4. Sensitivity analysis and count evacuees at 2, 5, and 10 miles

5. Prepare ETE times MOEs

1. 90 percent evacuation time (for all wind directions and scenarios, staged and normal evacuations)

a. This applies to evacuation of the PUBLIC only

2. 100 percent evacuation time (for all wind directions and scenarios, stage and normal evacuations)

3. Color-coded roadway map at various times (2, 4, 6 hrs) which identifies where long queues exist, including LOS E and F conditions.

Analysis of Evacuation Times 6.1 Evacuation Time Estimate Summary Predicted ETEs for the general population in the EPZ are summarized by scenario and distance in Table 6-1 (times for 90 percent and 100 percent of vehicles to depart, for 2-mile zones, all zones to 5 miles, and all zones to 10 miles). The pattern of evacuation times is consistent with the differences in vehicle demand and travel time for different scenarios. The 2-mile zone involves the shortest travel distance and the fewest vehicles; 90 percent ETEs for the 2-mile zone range from 2:25 to 3:55, and 100 percent ETEs are 4:00 to 6:20. The times are longest for summer weekday and winter weekday scenarios with adverse weather.

For the 2-mile plus all 5-mile zones, the 90 percent ETEs are 2:50 to 4:10, and the 100 percent ETEs are 4:20 to 6:30. For the full EPZ, the 90 percent ETEs are 3:15 to 4:25, while the 100 percent ETEs are 5:00 to 7:20.

All of these times are indicative of significant delays related to traffic congestion. The differences in vehicle demand between scenarios are up to 30 percent of total demand, and the predicted ETEs vary by up to 50 percent. Adverse weather adds more than an hour to the ETEs for the 2-mile zone, and more than 45 minutes to ETEs for the 5-mile zone and the full EPZ.

6.2 Comparison with Previous Study The ETEs for the current study are longer than the ETEs from the 2003 study. Vehicle demand for the full EPZ for the current study (22,307 for Winter Weekday) is about 20 percent higher than vehicle demand from 2003 (18,274), and the new 100 percent ETE (with adverse weather) is 7:00, compared to 3:45 in 2003. The current ETEs also reflect the addition of background traffic and longer departure times (based on the survey of residents).

6.3 Keyhole Evacuation Scenarios ETEs for scenarios that reflect the current range of Protective Action Recommendation (PAR) scenarios to evacuate the near-field population and selected downwind zones are summarized in Table 6-2. These results indicate that PAR scenarios involving Sub-Area 17 (most of the city of Byron) have the longest ETEs for evacuations 6-1

Exelon Generation Byron Station Evacuation Time Estimates extending to 5 miles downwind. All of the 5-mile zone and 10-mile downwind PAR scenarios have very similar ETEs.

6.4 Staged Evacuation Scenarios A series of staged evacuation scenarios were evaluated based on NRC guidance (CR-7002). In a staged evacuation, the 2-mile zone evacuates first, while surrounding zones shelter in place; after the population has evacuated the 2-mile zone, the outer zones would be instructed to evacuate. The stage 1 time is determined by simulating evacuation of the 2-mile zone for the Winter Weekday, Normal Weather scenario, with only background and shadow traffic in other parts of the EPZ. Once the Stage 1 time (2:40) was determined, a revised set of departure curves was developed for the outer (Stage 2) zones. The Stage 2 departure curves for Byron are shown in Figure 6-1.

The departure curves are much steeper at the beginning of Stage 2, because people are able to return home and prepare to depart during Stage 1.

Results for staged evacuation scenarios are summarized in Table 6-3. The ETEs for the staged scenarios are consistently longer than the corresponding unstaged ETEs, in several cases by an hour or more. The modeled results indicate that staged evacuation for Byron would result in little or no benefit, in terms of the time required to evacuate the 2-mile zone, and significant penalty, in terms of increased ETEs for the zones which would initially be ordered to shelter.

6.5 Sensitivity to Population Growth and Roadway Impact 6.5.1 Population Growth NRC guidance (CR-7002) for updating ETE studies more frequently than the 10-year federal census includes criteria based on population growth. Specifically, if the residential population growth in the EPZ since the last ETE update is sufficient to cause an increase in the ETE by 25 percent or by 30 minutes, whichever is less, then a full ETE update study must be performed.

A sensitivity analysis was performed by determining the 90 percent ETEs for increases of 5, 15 and 20 percent of the EPZ residential population for the Winter Weekday, Normal Weather scenario. This scenario produced the longest ETE by season or time of day. The population was increased in the same manner in the surrounding region, out to 15 miles. Results are illustrated in Figure 6-2. With a 15 percent increase in residential population above the 2010 census values, the 90 percent ETE for the full EPZ increased to 4:10, an increase of 30 minutes. Since the EPZ residential 6-2

Exelon Generation Byron Station Evacuation Time Estimates population for Byron changed by less than 8 percent between 2000 and 2010, it appears unlikely that an increase of 15 percent will occur before 2020.

The 100 percent ETEs increased more slowly than the 90 percent ETEs. With a 15 percent increase in population, the 100 percent ETE for the full EPZ increased by 20 minutes, from 6:15 to 6:35. NRC guidance (CR-7002) indicates that emergency planning decisions should be based on the 90 percent ETEs. The recommended update threshold for the Byron EPZ, based on population growth, is therefore 15 percent.

6.5.2 Roadway Impact NRC guidance (CR-7002) also requires analysis of a roadway impact scenario. For this scenario, a major evacuation route is removed or reduced in capacity. Specifically, one of the 5 highest volume roadways is removed from service, or capacity is reduced by one lane (for a multi-lane, limited-access roadway such as an interstate highway).

This scenario is specified as Summer Weekday, Normal Weather for the Full EPZ. For Byron, the five highest-volume roadways for this scenario are listed below:

• S Lowell Park Rd - 3,475 vehicles

• IL 72 westbound - 3,000 vehicles

• IL 2 northeast - 3,000 vehicles

• IL 2 (Oregon) - 1,900 vehicles

• IL 72 eastbound - 1,100 vehicles Predicted traffic volumes by link for the base case simulation with the full roadway network are shown in Figure 6-3.

One link in the highest-volume roadway, IL 72 westbound - west of Byron, was removed for the roadway impact scenario. The impact location is shown in Figure 6-4.

With this roadway unavailable, the ETEs increased from 3:35 (90 percent) and 6:15 (100 percent) to 3:44 (90 percent) and 7:57 (100 percent). With IL 72 westbound unavailable, traffic is primarily rerouted through IL 2 southwest of Byron.

Exelon Generation Byron Station Evacuation Time Estimates 6.6 Performance Metrics for Simulation Model The performance of VISSIM is assessed using standard metrics, consistent with the guidance provided in CR-7002. Table 6-4 provides a summary of simulation parameters for Winter Day Normal Weather scenario for the full EPZ. Figure 6-5 illustrates the number of vehicles on the network over the course of the simulation, while Figure 6-6 compares the rate of vehicles loading onto the network to the frequency of departures.

The parameters in Table 6-4 include an average travel speed for evacuating vehicles of 22.7 miles per hour, which indicates that traffic is encountering significant congestion during much of the simulation. The average travel time of 3.43 hours4.976852e-4 days <br />0.0119 hours <br />7.109788e-5 weeks <br />1.63615e-5 months <br /> reflects travel to the designated reception centers, rather than the travel time to exit the EPZ.

6.7 ETE for Transit Dependent Special Facilities and Schools The ETE for transit dependent members of the general public is estimated based on the assumption of a single set of bus runs from Byron, Oregon and Mt Morris. The run would begin 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> after the evacuation notice, allowing time for evacuees to prepare and to travel to designated pickup points. The time sequence would then proceed in the following steps:

• 30 minutes for the bus to traverse up to ten pickup points (2 miles) and load passengers (2:30)

• 40 minutes to travel out to reception center (8 miles @ 12 mph), and 10 minutes to unload (3:20)

Estimated evacuation times for special facilities, schools and daycares located in the EPZ are summarized in Tables 6-5 and 6-6. These times are shorter than the 90 percent and 100 percent ETEs for the general population. Facility-specific estimates are based on a three-step time sequence: (1) mobilization, (2) loading, and (3) travel out of the EPZ. Mobilization and loading times are generally the largest components.

At nursing homes and assisted living facilities, each vehicle will require about 10 minutes to load, with two vehicles loading simultaneously. While some school buses may mobilize more quickly depending on specific local circumstances, it will generally require on the order of 120 minutes to contact drivers, provide them with instructions and deploy them to assigned schools. Most of the students at Chana Education Center would evacuate in their own vehicles. For travel time, average speeds were estimated for the anticipated evacuation route, based on the traffic simulation for the Winter Day scenario. The simplified stepwise methodology used to determine these estimates 6-4

Exelon Generation Byron Station Evacuation Time Estimates provides a typical evacuation time, rather than an upper bound 90 percent or 100 percent value.

7. Traffic Control and Evacuation Confirmation 7.1 General Evacuation simulation results have been reviewed to assess access control locations, traffic management locations and recommendations for the Byron Station EPZ. Traffic control plans for each county were reviewed to confirm that traffic management will be implemented at key intersections on all designated evacuation routes. Predicted queuing at high-volume intersections is summarized in Table 7-1. Only four of those intersections are located inside the EPZ. The average queue length exceeds 200 feet at one signalized intersection on State Highway 2 in Byron. Similar queuing is predicted at a signalized intersection in Rockford on State Highway 251, more than 2 miles outside of the EPZ.

7.2 Evacuation Access Control Locations Access control measures were not specifically addressed in the conduct of this study.

Background traffic within the EPZ was not found to be a significant contributor to traffic congestion during the early stages of evacuation.

7.3 Traffic Management Locations and Tactics to Facilitate Evacuation The traffic simulation results for Byron indicate that traffic flow will encounter significant congestion in and around the city of Byron. The traffic flow maps provided in Appendix D and the data in Table 7-1 help to pinpoint locations where traffic management can be deployed to best effect. Congestion in Byron is predicted in the first hour and persists until hour 4. Congestion then develops along Kishwaukee Road and in several streets on the south side of Rockford, just outside the EPZ. The northeast corner of the network takes the longest to clear.
