==SUMMARY==
 
This report describes the analyses undertaken and the results obtained by a study to develop Evacuation Time Estimates (ETE) for the McGuire Nuclear Station (MNS) located in Mecklenburg County, North Carolina. This ETE study provides Duke Energy and offsite response organizations (OROs) with sitespecific information needed for protective action decisionmaking.
In the performance of this effort, guidance is provided by documents published by Federal Governmental agencies. Most important of these are:
Title 10, Code of Federal Regulations, Appendix E to Part 50 (10CFR50), Emergency Planning and Preparedness for Production and Utilization Facilities, NRC, 2011.
Criteria for Development of Evacuation Time Estimate Studies, NUREG/CR7002, Rev. 1, February 2021.
Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, NUREG 0654/Radiological Emergency Preparedness Program Manual, FEMA P1028, December 2019.
Project Activities This project began in November 2020 and extended over a period of 18 months. The major activities performed are briefly described in chronological sequence:
Conducted a virtual kickoff meeting with Duke Energy personnel and emergency management personnel representing state and county governments.
Accessed U.S. Census Bureau data files for the year 2020.
Studied Geographic Information Systems (GIS) maps of the area in the vicinity of the MNS, then conducted a detailed field survey of the highway network to observe any roadway changes relative to the previous ETE study done in 2019.
Updated the analysis network representing the highway system topology and capacities within the Emergency Planning Zone (EPZ), plus a Shadow Region covering the region between the EPZ boundary and approximately 15 miles radially from the plant.
Conducted a randomsample online demographic survey of residents within the EPZ, to gather focused data needed for this ETE study that were not contained within the census database. The survey instrument was reviewed and modified by the licensee and ORO personnel prior to the survey.
A data needs matrix (requesting data) was provided to Duke Energy and the OROs at the kickoff meeting. The data for major employers, transients, and special facilities (schools, preschools and childcare centers, medical and correctional facilities) gathered for the previous ETE study were reviewed and either confirmed or updated accordingly by the OROs. If updated information was not provided and could not be obtained from online sources, data gathered for the previous (2019) ETE study was utilized.

Evacuation Time Estimate                                                                      Rev. 0
 
Estimated the number of employees commuting into the EPZ is based on the 2018 Workplace Area Characteristic (WAC) data from the OnTheMap Census analysis tool1 extrapolated to 2020 using the shortterm employment projection for the State of North Carolina2.
The traffic demand and tripgeneration rates of evacuating vehicles were estimated from the gathered data. The trip generation rates reflected the estimated mobilization time (i.e., the time required by evacuees to prepare for the evacuation trip) computed using the results of the demographic survey of EPZ residents.
Following federal guidelines, the existing EPZ is subdivided into 19 zones. These zones are then grouped within circular areas or keyhole configurations (circles plus radial sectors) that define a total of 35 Evacuation Regions (numbered R01 through R35).
The timevarying external circumstances are represented as Evacuation Scenarios, each described in terms of the following factors: (1) Season (Summer, Winter); (2) Day of Week (Midweek, Weekend); (3) Time of Day (Midday, Evening); and (4) Weather (Good, Rain, Ice). One special event scenario involving a Carolina Renaissance Festival was considered. One roadway impact scenario was considered wherein a single lane was closed on Interstate77 (I77) southbound from the interchange with North Carolina 73/Sam Furr Rd (Exit 25) to the end of the analysis network at the interchange with County Route115/Sunset Rd (Exit 16A) for the duration of the evacuation.
Staged evacuation was considered for those regions wherein the 2Mile Radius and sectors downwind to 5 miles were evacuated.
As per NUREG/CR7002, Rev. 1, the Planning Basis for the calculation of ETE is:
A rapidly escalating accident at the MNS that quickly assumes the status of a general emergency wherein evacuation is ordered promptly, and no early protective action have been implemented such that the Advisory to Evacuate (ATE) is virtually coincident with the siren alert.
While an unlikely scenario, this planning basis will yield ETE, measured as the elapsed time from the ATE until the stated percentage of the population exits the impacted Region, that represent upper bound estimates. This conservative Planning Basis is applicable for all initiating events.
If the emergency occurs while schools, preschools and childcare centers are in session, the ETE study assumes that the children will be evacuated by bus directly to reception centers or relocation schools as stated in the MNS 2022 Emergency Preparedness Information3. Parents, relatives, and neighbors are advised to not pick up their children at school prior to the arrival of the buses dispatched for that purpose. The ETE for schoolchildren are calculated separately.

Evacuees who do not have access to a private vehicle will either rideshare with relatives, friends or neighbors, or be evacuated by buses provided by the counties in the EPZ. Those in special facilities will likewise be evacuated with public transit, as needed:
bus, van, wheelchair vehicle, or ambulance, as required. Separate ETE are calculated for the transitdependent evacuees, for access and/or functional needs population, and for those evacuated from special facilities.
Attended final virtual meeting with Duke Energy personnel and the OROs to present final results of the study.
Computation of ETE A total of 490 ETE were computed for the evacuation of the general public. Each ETE quantifies the aggregate evacuation time estimated for the population within one of the 35 Evacuation Regions to evacuate from that Region, under the circumstances defined for one of the 14 Evacuation Scenarios (35 x 14 = 490). Separate ETE are calculated for transitdependent evacuees, including schoolchildren for applicable scenarios.
Except for Region R03, which is the evacuation of the entire EPZ, only a portion of the people within the EPZ would be advised to evacuate. That is, the ATE applies only to those people occupying the specified impacted region. It is assumed that 100 percent of the people within the impacted region will evacuate in response to the ATE. The people occupying the remainder of the EPZ outside the impacted region may be advised to take shelter.
The computation of ETE assumes that 20% of the population within the EPZ but outside the impacted region, will elect to voluntarily evacuate. In addition, 20% of the population in the Shadow Region will also elect to evacuate. These voluntary evacuees could impede those who are evacuating from within the impacted region. The impedance that could be caused by voluntary evacuees is considered in the computation of ETE for the impacted region.
Staged evacuation is considered wherein those people within the 2Mile Radius evacuate immediately, while those beyond 2 miles, but within the EPZ, shelterinplace. Once 90% of the 2Mile Radius is evacuated, those people beyond 2 miles begin to evacuate. As per federal guidance, the assumed 20% of people beyond 2 miles evacuate (noncompliance) even though they are advised to shelterinplace.
The computational procedure is outlined as follows:
A linknode representation of the highway network is coded. Each link represents a unidirectional length of highway; each node usually represents an intersection or merge point. The capacity of each link is estimated based on the field survey observations and on established traffic engineering procedures.
The evacuation trips are generated at locations called zonal centroids located within the EPZ and Shadow Region. The trip generation rates vary over time reflecting the mobilization process, and from one location (centroid) to another depending on population density and on whether a centroid is within, or outside, the impacted area.

The evacuation model computes the routing patterns for evacuating vehicles that are compliant with federal guidelines (outbound relative to the location of the plant), then simulate the traffic flow movements over space and time. This simulation process estimates the rate that traffic flow exits the impacted region.
The ETE statistics provide the elapsed times for 90 percent and 100 percent, respectively, of the population within the impacted region, to evacuate from within the impacted region. These statistics are presented in tabular and graphical formats. The 90th percentile ETE have been identified as the values that should be considered when making protective action decisions because the 100th percentile ETE are prolonged by those relatively few people who take longer to mobilize. This is referred to as the evacuation tail in Section 4.0 of NUREG/CR7002, Rev. 1.
Traffic Management This study reviewed and modeled the existing traffic management plan within the EPZ provided by offsite response organizations within the EPZ. Nearly all of the traffic signals in the study area are actuated signals which will adapt their timing to the changing traffic patterns during evacuation. Based on the ETE simulations, 30 Traffic Control Points (TCP) and 8 Security Road Blocks (SRB) were modified to improve the ETE. Refer to Section 9 and Appendix G.
Selected Results A compilation of selected information is presented on the following pages in the form of Figures and Tables extracted from the body of the report; these are described below.
Table 31 presents the estimates of permanent resident population in each Zone based on the 2020 Census data.
Table 61 defines each of the 35 Evacuation Regions in terms of their respective groups of Zones.
Table 62 lists the 14 Evacuation Scenarios.
Tables 71 and 72 are compilations of ETE for the general population. These data are the times needed to clear the indicated regions of 90 and 100 percent of the population occupying these regions, respectively. These computed ETE include consideration of mobilization time and of estimated voluntary evacuations from other regions within the EPZ and from the Shadow Region.

Conclusions General population ETE were computed for 490 unique cases - a combination of 35 unique Evacuation Regions and 14 unique Evacuation Scenarios. Table 71 and Table 72 document these ETE for the 90th and 100th percentiles. These ETE range from 2:50 (hr:min) to 5:30 at the 90th percentile. The 100th percentile ETE ranges from 6:00 to 6:30 for good weather and rain cases, and from 6:30 to 7:30 for ice cases.
The comparison of Table 71 and Table 72 indicates that the ETE for the 100th percentile are significantly longer than those for the 90th percentile. The 100th percentile ETE for all regions for most of the nonice scenarios generally parallel the mobilization times (6:00 for residents with returning commuters plus 5 to 10 minutes travel time to exit the EPZ).
This implies that the congestion within the EPZ dissipates prior to the end of mobilization for nonice cases. For ice cases, the 100th percentile is significantly longer than the trip generation time, this is the result of the congestion within the EPZ. When the system becomes congested, traffic exits the EPZ at rates somewhat below capacity until some evacuation routes have cleared. As more routes clear, the aggregate rate of egress slows since many vehicles have already left the EPZ. Towards the end of the process, relatively few evacuation routes service the remaining demand. See Figures 7 10 through 723.
Inspection of Table 73 and Table 74 indicates that a staged evacuation provides no benefits to evacuees from within the 2Mile Radius and unnecessarily delays the evacuation of those beyond 2 miles (compare Regions R04 through R10 and R02 with Regions R28 through R35, respectively, in Tables 71 and 72). See Section 7.6 for additional discussion. Staged evacuation is not recommended for the MNS EPZ.
Comparison of Scenarios 9 (winter, weekend, midday, good weather) and 13 (winter, weekend, midday, good weather) in Table 72 indicates that the special event has minimal to no impact on the 90th percentile ETE (up to 15minute increases in ETE for some cases). There is no impact to the 100th percentile ETE. See Section 7.5 for additional discussion.
Comparison of Scenarios 1 and 14 in Table 71 and Table 72 indicates that the roadway closure - one lane southbound on I77 from the interchange with North Carolina73/
Sam Furr Rd (Exit 25) to the end of the analysis network at the interchange with County Route115/ Sunset Rd (Exit 16A) - does not have a material impact on 90th percentile ETE - increased by 15 minutes at most. There is no impact to the 100th percentile ETE.
See Section 7.5 for additional information.
Cornelius, Davidson and Huntersville population centers along I77 (on the eastern side of the EPZ) and roads accessing the ramps to the interstate are the most congested areas during an evacuation. The last location in the EPZ to exhibit traffic congestion is along I77 northbound. All congestion within the EPZ clears by 5 hours 40 minutes after the ATE. See Section 7.3 and Figures 73 through 710.
Separate ETE were computed for schools, preschools and childcare centers, medical facilities, correctional facility, transitdependent persons and access and/or functional needs persons. The average singlewave ETE for all these facilities except access and/or McGuire Nuclear Station                            ES5                          KLD Engineering, P.C.

functional needs population are lower than the general population ETE at the 90th percentile. The average twowave ETE for all these facilities except correctional facility exceeds the 90th percentile ETE for the general population and could affect protective action decision making. See Section 8.
Table 81 indicates that there are insufficient bus resources available to evacuate the transit dependent population in a single wave. Mutual aid agreements with neighboring counties and assistance from the state should be considered to address the shortfall in transportation resources (see Section 8.1).
A reduction or addition of base trip generation time by an hour impacts the 90th percentile ETE by 10 to 15 minutes and the 100th percentile ETE by 30 minutes to 1 hour (significant change). As discussed in Section 7.3, traffic congestion persists within the EPZ for about 5 hours and 30 minutes. If the time to mobilize is longer than 5 hours and 30 minutes, the 100th percentile ETE is dictated by trip generation time. For trip generation times less than 5 hours and 30 minutes, congestion dictates ETE. See Table M1 in Appendix M.
The general population ETE is sensitive to an increase of the voluntary evacuation of vehicles in the Shadow Region. For example, tripling the shadow evacuation percentage increases 90th percentile ETE by 30 minutes and 100th percentile ETE by 1 hour 5 minutes. See Table M2.
A population increase of 13% or more results in ETE changes which meet the NRC criteria for updating ETE between decennial Censuses. See Section M.3.
Based on the 2020 Census data, the average household size of 2.6 people per household was used for this study. As per the survey results, decreasing the average household size (increasing the total number evacuating vehicles) to 2.43 people per household has minimal impact on 90th percentile ETE (10 minutes longer at most). The 100th percentile ETE remains dictated by trip generation time and as a result is not impacted by the change in people per household. See Table M4.

1    INTRODUCTION This report describes the analyses undertaken and the results obtained by a study to develop Evacuation Time Estimates (ETE) for the McGuire Nuclear Station (MNS), located in Mecklenburg County, North Carolina. This ETE study provides Duke Energy, state and local governments with sitespecific information needed for Protective Action decisionmaking.
In the performance of this effort, guidance is provided by documents published by Federal governmental agencies. Most important of these are:
* Title 10, Code of Federal Regulations, Appendix E to Part 50 (10CFR50), Emergency Planning and Preparedness for Production and Utilization Facilities, NRC, 2011.
* Criteria for Development of Evacuation Time Estimate Studies, NUREG/CR7002, Rev.
1, February 2021.
* Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, NUREG 0654/Radiological Emergency Preparedness Program Manual, FEMA P1028, December 2019.
The work effort reported herein was supported and guided by local stakeholders who contributed suggestions, critiques, and the local knowledge base required. Table 11 presents a summary of stakeholders and interactions.
1.1    Overview of the ETE Process The following outline presents a brief description of the work effort in chronological sequence:
: 1. Information Gathering:
: a. Defined the scope of work in discussions with representatives from Duke Energy.
: b. Attended a project kickoff meetings with personnel from Duke Energy, the emergency planners of the Counties of Mecklenburg, Lincoln, Gaston, Iredell, and Catawba, and the State of North Carolina to discuss methodology, project assumptions and to identify issues to be addressed and resources available.
: c. Conducted a detailed field survey of the highway system and of area traffic conditions within the Emergency Planning Zone (EPZ) and Shadow Region.
: d. Reviewed existing county and state Emergency Operations Plans.
: e. Conducted an online demographic survey of EPZ residents (See Appendix F).
: f. Obtained demographic data from the 2020 Census (see Section 3.1).
: g. Conducted a data collection effort to identify and describe special facilities (i.e.,
schools, preschools and childcare centers, medical facilities, and correctional facilities), major employers, access and/or functional needs populations, McGuire Nuclear Station                          11                            KLD Engineering, P.C.

transportation resources available, the special event, and other important information.
: 2. Estimated distributions of trip generation times representing the time required by various population groups (permanent residents, employees, and transients) to prepare (mobilize) for the evacuation trip. These estimates are primarily based upon the online demographic survey.
: 3. Defined Evacuation Scenarios (See Section 6). These scenarios reflect the variation in demand, in trip generation distribution and in highway capacities, associated with different seasons, day of week, time of day and weather conditions.
: 4. Reviewed the existing traffic management plan to be implemented by local and state police in the event of an incident at the plant. Traffic control is applied at specified Traffic Control Points (TCP) and Security Road Blocks (SRB) located within the study area. Eight (8) SRB and 30 TCP modifications were made in areas where it would benefit the ETE. See Section 9 and Appendix G (Table G2).
: 5. Used existing Zones to define Evacuation Regions. The EPZ is partitioned into 19 Zones along jurisdictional and geographic boundaries. Regions are groups of contiguous Zones for which ETE are calculated. The configurations of these Regions reflect wind direction and the radial extent of the impacted area. Each Region, other than those that approximate circular areas, approximates a keyhole section within the EPZ as recommended by NUREG/CR7002, Rev.1.
: 6. Estimated demand for transit services for persons at schools, preschools/childcare centers, medical facility, transit dependent people at home, and those with access and/or functional needs.
: 7. Prepared the input streams for the DYNEV II which computes ETE (see Appendices B and C).
: a. Estimated the evacuation traffic demand, based on the available information derived from Census data, and from data provided by local and state agencies, Duke Energy, and from the demographic survey.
: b. Updated the linknode representation of the evacuation network, which is used as the basis for the computer analysis that calculates the ETE.
: c. Applied the procedures specified in the 2016 Highway Capacity Manual (HCM 20161) to the data acquired during the field survey, to estimate the capacity of all highway segments comprising the evacuation routes.
: d. Updated the linknode representation of the evacuation network using the field survey and aerial imagery, which is used as the basis for the computer analysis that calculates the ETE.

1.2    The McGuire Nuclear Station Location The MNS is located along the shores of Lake Norman in Huntersville, Mecklenburg County, North Carolina. The site is approximately 15 miles northnorthwest of Charlotte, NC. The EPZ consists of parts of Mecklenburg, Lincoln, Gaston, Iredell, and Catawba Counties in North Carolina. Figure 11 displays the area surrounding the MNS. This map identifies the major population centers, and the major roads in the area, and the location of the plant relative to Charlotte, NC.
1.3    Preliminary Activities These activities are described below.
Field Surveys of the Highway Network In December 2020, KLD personnel drove the entire highway system within the EPZ and the Shadow Region which consists of the area between the EPZ boundary and approximately 15 miles radially from the plant. The characteristics of each section of highway were recorded. These characteristics are shown in Figure 12.
Video and audio recording equipment were used to capture a permanent record of the highway infrastructure. No attempt was made to meticulously measure such attributes as lane width and shoulder width; estimates of these measures based on visual observation and recorded images were considered appropriate for the purpose of estimating the capacity of highway sections. For example, Exhibit 157 in the HCM 2016 indicates that a reduction in lane width from 12 feet (the base value) to 10 feet can reduce free flow speed (FFS) by 1.1 mph - not a material difference
- for twolane highways. Exhibit 1546 in the HCM 2016 shows little sensitivity for the estimates of Service Volumes at Level of Service (LOS) E (near capacity), with respect to FFS, for twolane highways.
The data from the audio and video recordings were used to create detailed geographic information systems (GIS) shapefiles and databases of the roadway characteristics and of the McGuire Nuclear Station                          13                              KLD Engineering, P.C.

traffic control devices observed during the road survey; this information was referenced while preparing the input stream for the DYNEV II System. Roadway types were assigned based on the following criteria:
Freeway: limited access highway, 2 or more lanes in each direction, high free flow speeds Freeway Ramp: ramp on to or off of a limited access highway Major Arterial: 3 or more lanes in each direction Minor Arterial: 2 lanes in each direction Collector: single lane in each direction Local Roadway: single lane in each direction, local road with low free flow speeds As documented on page 156 of the HCM 2016, the capacity of a twolane highway is 1,700 passenger cars per hour in one direction. For freeway sections, a value of 2,250 vehicles per hour per lane is assigned, as per Exhibit 1237 of the HCM 2016. The road survey has identified several segments which are characterized by adverse geometrics on twolane highways which are reflected in reduced values for both capacity and speed. These estimates are consistent with the service volumes for LOS E presented in HCM 2016 Exhibit 1546. Link capacity is an input to DYNEV II which computes the ETE. Further discussion of roadway capacity is provided in Section 4 of this report.
Traffic signals are either pretimed (signal timings are fixed over time and do not change with the traffic volume on competing approaches) or are actuated (signal timings vary over time based on the changing traffic volumes on competing approaches). Actuated signals require detectors to provide the traffic data used by the signal controller to adjust the signal timings. These detectors are typically magnetic loops in the roadway, or video cameras mounted on the signal masts and pointed toward the intersection approaches. If detectors were observed on the approaches to a signalized intersection during the road survey, detailed signal timings were not collected as the timings vary with traffic volume. TCPs at locations which have control devices are represented as actuated signals in the DYNEV II system.
If no detectors were observed, the signal control at the intersection was considered pretimed, and detailed signal timings were gathered for several signal cycles. These signal timings were input to the DYNEV II system used to compute ETE, as per NUREG/CR7002, Rev. 1 guidance.
Figure 12 presents the linknode analysis network that was constructed to model the evacuation roadway network in the EPZ and Shadow Region. The directional arrows on the links and the node numbers have been removed from Figure 12 to clarify the figure. The detailed figures provided in Appendix K depict the analysis network with directional arrows shown and node numbers provided. The observations made during the field survey and aerial imagery were used to calibrate the analysis network.
The linknode analysis network from the previous study was updated to include newly constructed and ongoing roadway improvements based on data collected during the road survey. Aerial imagery, the roadway survey and roadway design plans (to the extent available) were used to update the network.

Demographic Survey An online demographic survey was performed in 2021 to gather information needed for the evacuation study. Appendix F presents the survey instrument, the procedures used, and tabulations of data compiled from the survey returns along with discussion validating the use of the survey results in this study.
These data were utilized to develop estimates of vehicle occupancy, to estimate the number of evacuating vehicles during an evacuation, and to estimate elements of the mobilization process.
This database was also referenced to estimate the number of transitdependent residents.
Developing the Evacuation Time Estimates The overall study procedure is outlined in Appendix D. Demographic data were obtained from several sources, as detailed later in this report. These data were analyzed and converted into vehicle demand data. The vehicle demand was loaded onto appropriate source links of the analysis network using GIS mapping software. The DYNEV II model was then used to compute ETE for all Regions and Scenarios.
Analytical Tools The DYNEV II System that was employed for this study is comprised of several integrated computer models. One of these is the DYNEV (DYnamic Network EVacuation) macroscopic simulation model, a new version of the IDYNEV Model that was developed by KLD under contract with the Federal Emergency Management Agency (FEMA).
DYNEV II consists of four submodels:
A macroscopic traffic simulation model (for details, see Appendix C).
A Trip Distribution (TD) model, that assigns a set of candidate destination (D) nodes for each origin (O) located within the analysis network, where evacuation trips are generated over time. This establishes a set of OD tables.
A Dynamic Traffic Assignment (DTA) model, which assigns trips to paths of travel (routes) which satisfy the OD tables, over time. The TD and DTA models are integrated to form the DTRAD (Dynamic TRaffic Assignment and Distribution) model, as described in Appendix B.
A Myopic Traffic Diversion model, which diverts traffic to avoid intense, local congestion, if possible.
Another software product developed by KLD, named UNITES (UNIfied Transportation Engineering System) was used to expedite data entry and to automate the production of output tables.
The dynamics of traffic flow over the network are graphically animated using the software product, EVAN (EVacuation ANimator), developed by KLD. EVAN is GIS based and displays statistics output by the DYNEV II System, such as LOS, vehicles discharged, average speed, and percent of vehicles evacuated. The use of a GIS framework enables the user to zoom in on areas of congestion and query road name, town name, and other geographical information.

The procedure for applying the DYNEV II System within the framework of developing ETE is outlined in Appendix D. Appendix A is a glossary of terms.
For the reader interested in an evaluation of the original model, IDYNEV, the following references are suggested:
NUREG/CR4873 - Benchmark Study of the IDYNEV Evacuation Time Estimate Computer Code NUREG/CR4874 - The Sensitivity of Evacuation Time Estimates to Changes in Input Parameters for the IDYNEV Computer Code The evacuation analysis procedures are based upon the need to:
Route traffic along paths of travel that will expedite their travel from their respective points of origin to points outside the EPZ.
Restrict movement toward the plant to the extent practicable and disperse traffic demand so as to avoid focusing demand on a limited number of highways.
Move traffic in directions that are generally outbound, relative to the location of the plant.
DYNEV II provides a detailed description of traffic operations on the evacuation network. This description enables the analyst to identify bottlenecks and to develop countermeasures that are designed to represent the behavioral responses of evacuees. The effects of these countermeasures may then be tested with the model.
1.4    Comparison with Prior ETE Study Table 13 presents a comparison of the present ETE study with the 2019 study (KLD TR 1075, dated September 2019). As indicated in the final row of the table, the ETE values have significantly changed since the last ETE update. The 90th percentile ETE for full EPZ (Region R03),
decreases by as much as 1 hour 25 minutes when compared to the 2019 study. The 100th percentile ETE for the full EPZ decreases by as much as 2 hours and 40 minutes. While for the evening scenarios (5 and 12), the 90th and 100th percentile ETE for the full EPZ increases by as much as 15 minutes, and 1 hour 15 minutes, respectively. These cases are primarily dictated by the time to mobilize, which has increased.
The major factors contributing to the significant changes between the ETE values obtained in this study and those of the previous study can be summarized as follows:
Despite the EPZ population growing 6.2% (and shadow population up by 4.1%) since 2019, the distribution of the population is very different. The 2019 population was estimated based on 2010 Census blocks projected out to 2019 using 2017 growth rate. Areas with new development are not accurately captured by this method of estimating population.
If a Census block had zero people in 2010 at a location wherein a new community has been built, it will remain zero regardless of the growth rate applied. The population distribution utilized in this study is based on 2020 Census data, which is more accurate.

redistribution of evacuation demand can increase or decrease ETE depending on where the vehicles are originating.
Furthermore, the population in Zones A, B, C, D, and E (on the eastern portion of the EPZ) actually decreased compared to previous study (compare Table 33 from KLD TR1075 to Table 31 in this report). Evacuees from these zones use I77 as primary evacuation route.
This decrease in traffic demand helps improve the operation of I77 and can decrease the ETE, especially since I77 is the last roadway to clear of congestion.
The number of employees commuting into the EPZ decreased significantly by 24.4%, due to the updated NRCs criteria for major employers from 50 or more employees per shift to 200 or more employees per shift. A decrease in the number of employee vehicles can decrease the ETE.
There are significant decreases in the transitdependent population (70.5%) which results in less evacuating vehicles within the EPZ, which can reduce the ETE. This is because the percentage of ridesharing with neighbors, friends or family for resident with non returning commuters increased to 72% compared to 50% used in the previous study.
There is a 69.4% decrease in commuter student population, which is a result of the use of more accurate data. This could increase or decrease the ETE.
The express lanes on Interstate77 (I77) were partially constructed (Exit 19/I485 to Exit 36/W Plaza Dr) during the last study. The construction of these lanes has completed since the last study. As such, this study considers all 26 miles of I77 Express Lanes from the Brookshire Freeway (Exit 11/I277) in Mecklenburg County to N.C. 150 (Exit 36/ W Plaza Dr) in Iredell County. This improvement in roadway capacity can decrease the ETE.
Trip mobilization (also known as trip generation), based on the data collected from the demographic survey, has increased. For cases wherein trip mobilization dictates ETE, this is directly correlated to the increase in ETE.
The various factors, discussed above, that can decrease the ETE outweigh those that can increase the ETE, thereby explaining why the 90th and 100th percentile ETE have significantly decreased for all cases (except evening cases) in this study relative to the 2019 ETE study.

2      STUDY ESTIMATES AND ASSUMPTIONS This section presents the estimates and assumptions utilized in the development of the evacuation time estimates (ETE).
2.1      Data Estimate Assumptions
: 1. The permanent resident population are based on the 2020 U.S. Census population from the Census Bureau website1. A methodology, referred to as the area ratio method, is employed to estimate the population within portions of census blocks that are divided by Zone boundaries. It is assumed that the population is evenly distributed across a census block in order to employ the area ratio method (See Section 3.1.)
: 2. Estimates of employees who reside outside the Emergency Planning Zone (EPZ) and commute to work within the EPZ are based on the 2018 Workplace Area Characteristic (WAC) data from the OnTheMap Census analysis tool2 extrapolated to 2020 using the shortterm employment projection for the State of North Carolina3. (See Section 3.4.)
: 3. Population estimates at transient and special facilities are based on the data received from the counties within the EPZ, the National Center for Education Statistics website4, the North Carolina Division of Child Development and Early Education5, the Health Resources and Services Administration6, the NC Department of Health and Human Services7 and the old data from the previous ETE study, supplemented by internet searches and aerial imagery for parking spaces where data was missing.
: 4. The relationship between permanent resident population and evacuating vehicles was based on 2020 Census and the results of the online demographic survey (see Appendix F), based on discussions with Duke Energy. Average values of 2.60 persons per household (Figure F1) and 1.31 evacuating vehicles per household (Figure F10) are used for permanent resident population.
: 5. Where data was not provided, the average household size is assumed to be the vehicle occupancy rate for transient facilities and the special event. On average, the relationship between persons and vehicles for transients and the special event is as follows:
: a. Campgrounds: 1.79 people per vehicle
: b. Golf Courses: 2.29 people per vehicle
: c. Historical Sites: 1.94 people per vehicle
: d. Marinas: 2.59 people per vehicle
: e. Parks: 2.00 people per vehicle
: f. Other Recreational Areas: 2.67 people per vehicle 1

: g. Lodging facilities: 2.52 people per vehicle
: h. Special Event: 2.60 people per vehicle
: 6. Employee vehicle occupancies are based on the results of the demographic survey; 1.09 employees per vehicle is used in the study (See Figure F7). In addition, it is assumed there are two people per carpool, on average.
: 7. The maximum bus speed assumed within the EPZ is 45 mph based on North Carolina state laws8 for buses and average posted speed limits on roadways within the EPZ.
: 8. Roadway capacity estimates are based on field surveys performed in 2020 (verified by aerial imagery), and the application of the Highway Capacity Manual 2016.
2.2        Methodological Assumptions
: 1. The Planning Basis Assumption for the calculation of ETE is a rapidly escalating accident that requires evacuation, and includes the following9 (as per NRC guidance):
: a. Advisory to Evacuate (ATE) is announced coincident with the siren notification.
: b. Mobilization of the general population will commence within 15 minutes after siren notification.
: c. ETE are measured relative to the ATE.
: 2. The centerpoint of the plant is located at the center of the containment building 35°25'59.42"N, 80°56'54.16" W.
: 3. The DYNEV II10 (Dynamic Network EVacuation) macroscopic simulation model is used to compute ETE in this study.
: 4. Evacuees will drive safely, travel radially away from the plant to the extent practicable given the highway network, and obey all control devices and traffic guides. All major evacuation routes are used in the analysis.
: 5. The existing EPZ and Zone boundaries are used. See Figure 31.
: 6. The Shadow Region extends to 15 miles radially from the plant or approximately 5 miles radially from the EPZ boundary, as per NRC guidance. See Figure 72.
: 7. One hundred percent (100%) of the people within the impacted keyhole will evacuate.
Twenty percent (20%) of the population within the Shadow Region and within Zones of the EPZ not advised to evacuate will voluntarily evacuate, as shown in Figure 21, as per 8
https://www.ncdot.gov/dmv/license-id/driver-licenses/new-drivers/Documents/school-bus-handbook.pdf 9
We emphasize that the adoption of this planning basis is not a representation that these events will occur within the indicated time frame. Rather, these assumptions are necessary in order to:
: 1. Establish a temporal framework for estimating the Trip Generation distribution in the format recommended in Section 2.13 of NUREG/CR-6863.
: 2. Identify temporal points of reference that uniquely define "Clear Time" and ETE.
It is likely that a longer time will elapse between the various stages of an emergency. See Section 5.1 for more detail.
10 The models of the I-DYNEV System were recognized as state of the art by the Atomic Safety & Licensing Board (ASLB) in past hearings. (Sources: Atomic Safety & Licensing Board Hearings on Seabrook and Shoreham; Urbanik). The models have continuously been refined and extended since those hearings and were independently validated by a consultant retained by the NRC. The DYNEV II model incorporates the latest technology in traffic simulation and in dynamic traffic assignment.

NRC guidance. Sensitivity studies explore the effect on ETE of increasing the percentage of voluntary evacuees in the Shadow Region (see Appendix M).
: 8. Shadow population characteristics (household size, evacuating vehicles per household, and mobilization time) is assumed to be the same as that of the permanent resident population within the EPZ.
: 9. ETE are presented at the 90th and 100th percentiles, as well as in graphical and tabular format, as per NRC guidance. The percentile ETE is defined as the elapsed time from the ATE issued to a specific Region of the EPZ, to the time that Region is clear of the indicated percentile of evacuees.
: 10. This study does not assume that roadways are empty at the start of the first time period.
Rather, there is an initialization period (often referred to as fill time in traffic simulation) wherein the traffic volumes from the first time period are loaded onto roadways in the study area. The amount of initialization/fill traffic that is on the roadways in the study area at the start of the first time period depends on the scenario and the region being evacuated. See Section 3.12.
: 11. To account for boundary conditions beyond the study area, this study assumes a 25%
reduction in capacity on twolane roads and multilane highways for roadways that have traffic signals downstream. The 25% reduction in capacity is based on the prevalence of actuated traffic signals in the study area and the fact that the evacuating traffic volume will be more significant than the competing traffic volume at any downstream signalized intersections, thereby warranting a more significant percentage (75% in this case) of the signal green time. There is no reduction in capacity for freeways due to boundary conditions.
: 12. The ETE also include consideration of through (ExternalExternal) trips during the time that such traffic is permitted to enter the evacuated Region (see Section 3.11).
2.3  Assumptions on Mobilization Times
: 1. Trip generation time (also known as mobilization time, or the time required by evacuees to prepare for the evacuation) are based upon the results of the online demographic survey (See Section 5 and Appendix F). It is assumed that stated events take place in sequence such that all preceding events must be completed before the current event can occur.
: 2. One hundred percent (100%) of the EPZ population can be notified within 45 minutes, in accordance with the 2019 Federal Emergency Management Agency (FEMA) Radiological Emergency Preparedness Program Manual.
: 3. Commuter percentages (and percentage of residents awaiting the return of a commuter) are based on the results of the demographic survey. According to the survey results, 43% of the households in the EPZ have at least 1 commuter; 51% of those households with commuters will await the return of a commuter before beginning their evacuation McGuire Nuclear Station                          23                            KLD Engineering, P.C.
Evacuation Time Estimate                                                                      Rev. 0
 
trip (see Section F.3.2.). Therefore, 22 percent (43% x 51% = 22%) of EPZ households will await the return of a commuter, prior to beginning their evacuation trip.
2.4      Transit Dependent Assumptions
: 1. The percentage of transitdependent people who will rideshare with a neighbor or friend are based on the results of the demographic survey. According to the survey results, approximately 72 percent of the transitdependent population will rideshare.
: 2. Transit vehicles are used to transport those without access to private vehicles:
: a. Schools, preschools and/or childcare centers
: i. If schools are in session, buses will evacuate students directly to the designated relocation schools.
ii. It is assumed that no school children will be picked up by their parents prior to the arrival of the buses. As stated in the McGuire Nuclear Station 2022 Emergency Preparedness Information11, for Lincoln County all childcare facilities will be moved to S. Ray Lowder Elementary school and all private schools not specifically listed will be moved to Lincolnton Middle School. All other childcare facilities in the EPZ will be evacuated to the reception center for the Zone in which that facility is located.
iii. Schoolchildren, if school is in session, are given priority in assigning transit vehicles.
: b. Medical Facilities I. Buses, vans, wheelchair buses, wheelchair vans, and ambulances will evacuate patients at medical facilities and at any senior facilities within the EPZ, as needed.
II. Since the percent breakdown of ambulatory, wheelchair bound and bedridden patients varies by day or even by hour, data from the previous ETE study was used to determine representative percentages for the number of ambulatory, wheelchair bound and bedridden patients at the medical facilities wherein new data was not provided.
: c. Transitdependent permanent residents:
I. Transitdependent general population are evacuated to reception centers.
II. Access and/or functional needs population may require county assistance (ambulance, bus or wheelchair transport) to evacuate. This is considered separately from the general population ETE, as per NRC guidance.
III. Households with 3 or more vehicles were assumed to have no need for transit vehicles.

Evacuation Time Estimate                                                                            Rev. 0
: 2. TCP and SRB are assumed to be staffed approximately 120 minutes after the ATE, as per NRC guidance. It is assumed that no through traffic will enter the EPZ after this 120 minute period.
: 3. It is assumed that all transit vehicles and other responders entering the EPZ to support the evacuation are unhindered by personnel manning TCPs and SRBs.
2.6  Scenarios and Regions
: 1. A total of 14 Scenarios representing different temporal variations (season, time of day, day of week) and weather conditions are considered. Scenarios to be considered are defined in Table 21:
: a. The Carolina Renaissance Festival located in Zone G, is considered as the special event (single or multiday event that attracts a significant population into the EPZ; recommended by NRC guidance) for Scenario 13.
: b. As per NRC guidance, one of the top 5 highest volume roadways must be closed or one lane outbound on a freeway must be closed for a roadway impact scenario. This study considers the closure of one southbound lane on Interstate 77 (I77) from the interchange with North Carolina73 (NC73)/Sam Furr Rd (Exit
: 25) to the end of the analysis network at the interchange with County Route 115/Sunset Rd (Exit 16A) for the roadway impact scenario - Scenario 14.
: 2. Two types of adverse weather scenarios are considered. Rain may occur for either winter or summer scenarios; ice occurs in winter scenarios only. It is assumed that the rain or ice begins earlier or at about the same time the evacuation advisory is issued. No weatherrelated reduction in the number of transients who may be present in the EPZ is assumed. It is assumed that roads are passable and that the appropriate agencies are clearing/treating the roads as they would normally with ice and the roads are passable albeit at lower speeds and capacities.
: 3. Adverse weather scenarios affect roadway capacity and the free flow highway speeds.
Transportation research indicates capacity and speed reductions of about 10% for rain and 20% for ice. In accordance with Table 31 of Revision 1 to NUREG/CR7002, this study assumes a 10% and 20% reduction in speed and capacity for rain and ice, respectively. The factors are shown in Table 22.
: 4. It is also assumed that mobilization and loading times for transit vehicles are slightly longer in adverse weather. It is assumed that mobilization times are 10 minutes and 20 minutes longer in rain and ice, respectively. It is assumed that loading times are 5 minutes and 10 minutes longer for school buses and 10 minutes to 20 minutes longer for transit buses in rain and ice, respectively. Refer to Table 22.
: 5. It is assumed that employment is reduced slightly (4% reduction) in the summer for vacations.

: 6. Regions are defined by the underlying keyhole or circular configurations as specified in Section 1.4 of NUREG/CR7002, Rev. 1. These Regions, as defined, display irregular boundaries reflecting the geography of the Zone included within these underlying configurations. All 16 cardinal and intercardinal wind direction keyhole configurations are considered. Regions to be considered are defined in Table 61. It is assumed that everyone within the group of Zones forming a Region that is issued an ATE will, in fact, respond and evacuate in general accord with the planned routes.
: 7. Due to the irregular shapes of the Zones, there are instances where a small portion of a Zone (a sliver) is within the keyhole and the population within that small portion is low (less than 500 people or 10% of the Zone population, whichever is less). Under those circumstances, the Zone is not included in the Region so as to not evacuate large numbers of people outside of the keyhole for a small number of people that are actually in the keyhole, unless otherwise stated in the Protective Action Recommendation (PAR) document.
: 8. Staged evacuation is considered as defined in NUREG/CR7002, Rev. 1 - those people between 2 and 5 miles will shelterinplace until 90% of the 2Mile Radius has evacuated, then they will evacuate.

3    DEMAND ESTIMATION The estimates of demand, expressed in terms of people and vehicles, constitute a critical element in developing an evacuation plan. These estimates consist of three components:
: 1. An estimate of population within the EPZ, stratified into groups (e.g., resident, employee, transient, special facilities, etc.).
: 2. An estimate, for each population group, of mean occupancy per evacuating vehicle. This estimate is used to determine the number of evacuating vehicles.
: 3. An estimate of potential doublecounting of vehicles.
Appendix E presents much of the source material for the population estimates. Our primary source of population data, the 2020 Census, is not adequate for directly estimating some transient groups.
Throughout the year, vacationers and tourists enter the EPZ. These nonresidents may dwell within the EPZ for a short period (e.g., a few days or one or two weeks), or may enter and leave within one day. Estimates of the size of these population components must be obtained, so that the associated number of evacuating vehicles can be ascertained.
The potential for doublecounting people and vehicles must be addressed. For example:
A resident who works and shops within the EPZ could be counted as a resident, again as an employee and once again as a shopper.
A visitor who stays at a hotel and spends time at a park, then goes shopping could be counted three times.
Furthermore, the number of vehicles at a location depends on time of day. For example, motel parking lots may be full at dawn and empty at noon. Similarly, parking lots at area parks, which are full at noon, may be almost empty at dawn. Estimating counts of vehicles by simply adding up the capacities of different types of parking facilities will tend to overestimate the number of transients and can lead to ETE that are too conservative.
Analysis of the population characteristics of the MNS EPZ indicates the need to identify three distinct groups:
Permanent residents - people who are year round residents of the EPZ.
Transients - people who reside outside of the EPZ who enter the area for a specific purpose (shopping, recreation) and then leave the area.
Employees - people who reside outside of the EPZ and commute to work within the EPZ on a daily basis.
Estimates of the population and number of evacuating vehicles for each of the population groups are presented for each Zone and by polar coordinate representation (population distribution). The MNS EPZ is subdivided into 19 Zones. The Zones comprising the EPZ are shown in Figure 31.

Evacuation Time Estimate                                                                        Rev. 0
 
3.1    Permanent Residents The primary source for estimating permanent population is the latest U.S. Census data with an availability date of September 16, 2021. The average household size (2.60 persons/household was estimated based on the 2020 Census data - See Appendix F, Subsection F.3.1). The number of evacuating vehicles per household (1.31 vehicles/household - See Appendix F, Sub section F.3.2) was adapted from the demographic survey.
The permanent resident population is estimated by cutting the census block polygons by the Zone and EPZ boundaries using GIS software. A ratio of the original area of each census block and the updated area (after cutting) is multiplied by the total block population to estimate the population within the EPZ. This methodology (referred to as the area ratio method) assumes that the population is evenly distributed across a census block. Table 31 provides permanent resident population within the EPZ, by Zone, for 2010 and for 2020 (based on the methodology above). As indicated, the permanent resident population within the EPZ has increased by 27.6%
since the 2010 Census.
To estimate the number of vehicles, the year 2020 permanent resident population is divided by the average household size and multiplied by the average number of evacuating vehicles per household. Permanent resident population and vehicle estimates are presented in Table 32.
Figure 32 and Figure 33 present the permanent resident population and permanent resident vehicle estimates by sector and distance from MNS. This population rose was constructed using GIS software. Note, the 2020 Census includes residents living in group quarters, such as skilled nursing facilities, group homes, prisons, college/university student housing, etc. These people are transit dependent (will not evacuate in personal vehicles) and are included in the special facility evacuation demand estimates. To avoid double counting vehicles, the vehicle estimates for these people have been removed. The resident vehicles in Table 32 and Figure 33 have been adjusted accordingly.
3.2    Shadow Population A portion of the population living outside the evacuation area extending to 15 miles radially from the MNS may elect to evacuate without having been instructed to do so. This area is called the Shadow Region. Based upon NUREG/CR7002, Rev. 1 guidance, it is assumed that 20 percent of the permanent resident population, based on U.S. Census Bureau data, in the Shadow Region will elect to evacuate.
Shadow population characteristics (household size, evacuating vehicles per household, mobilization time) are assumed to be the same as that for the EPZ permanent resident population. Table 33, Figure 34, and Figure 35 present estimates of the shadow population and vehicles, by sector. Similar to the EPZ resident vehicle estimates, resident vehicles at group quarters have been removed from the shadow population vehicle demand in Table 33 and Figure 35.

3.3      Transient Population Transient population groups are defined as those people (who are not permanent residents, nor commuting employees) who enter the EPZ for a specific purpose (shopping, recreation).
Transients may spend less than one day or stay overnight at camping facilities, hotels and motels.
Data from the 2019 ETE study was reviewed by the counties within the EPZ and confirmed to be still accurate. In addition to the preexisting transient facilities from the previous study, a number of new transient facilities were identified within the EPZ. Data for the new facilities were provided by counties and supplemented by internet searches and aerial imagery where data could not provided. It is assumed transients would travel to transient facilities as a family/household. As such, the average household size of 2.60 persons per household (see Section 3.1) was used for facilities with missing transient population. The transient facilities within the MNS EPZ are summarized as follows:
Campgrounds - 125 transients and 70 vehicles; an average of 1.79 transients per vehicle Golf Courses - 439 transients and 192 vehicles; an average of 2.29 transients per vehicle Historical Sites - 1,480 transients and 762 vehicles; an average of 1.94 transients per vehicle Marinas - 892 transients and 345 vehicles; an average of 2.59 transients per vehicle Parks - 376 transients and 188 vehicles; an average of 2.00 transients per vehicle Other Recreational Areas - 1,603 transients and 601 vehicles; an average of 2.67 transients per vehicle Lodging Facilities - 6,069 transients and 2,411 vehicles; an average of 2.52 transients per vehicle Appendix E summarizes the transient data that was estimated for the EPZ. Table E5 through Table E7 present the number of transients visiting recreational areas, while Table E8 presents the number of transients at lodging facilities within the EPZ.
In total, there are 10,984 transients evacuating in 4,569 vehicles (an average of 2.40 transients per vehicle) in the EPZ. Table 34 presents transient population and transient vehicle estimates by Zone. Figure 36 and Figure 37 present these data by sector and distance from the plant.
3.4        Employees The estimate of employees commuting into the EPZ is based on the 2018 Workplace Area Characteristic (WAC) data from the OnTheMap Census analysis tool1 extrapolated to 2020 using the shortterm employment projection for the State of North Carolina2.
The WAC data provides the employee counts by industry sector for each census block within the MNS EPZ. Since not all employees are working at facilities within the EPZ at one time, a 1

maximum shift reduction was applied to each census block. Assuming maximum shift employment occurs Monday through Friday between 9 AM and 5 PM, the following jobs take place outside the typical 95 workday:
Manufacturing - takes place in shifts over 24 hours Arts, Entertainment, and Recreation - takes place in evenings and on weekends Accommodations and Food Services - peaks in the evenings Therefore, the number of employees working in these three industry sectors was subtracted from the total number for each census block to represent the maximum number of employees present in the EPZ at any one time. As per the NUREG/CR7002, Rev. 1 guidance, employers with 200 or more employees working in a single shift are considered as the major employers.
As such, the census blocks with less than 200 employees (during the maximum shift) are not included in this study.
Employees who work within the EPZ fall into two categories:
Those who live and work in the EPZ Those who live outside of the EPZ and commute to jobs within the EPZ.
Those of the first category are already counted as part of the permanent resident population. To avoid double counting, we focus only on those employees commuting from outside the EPZ who will evacuate along with the permanent resident population. The 2018 LEHD (Longitudinal EmployerHousehold Dynamics) OriginDestination Employment Statistics (LODES) data3 from OnTheMap website was then used to estimate the percent of employees that work within the EPZ but live outside. This value, 75.6%, was applied to the maximum shift employee values to compute the number of people commuting to work in the EPZ at peak times.
Plant employment data and percent of employees commuting into the EPZ was provided by Duke Energy and supplemented for the census block in Zone B. As such, the plant employment data is reflected in the Mecklenburg County employment subtotal in Table E4 of Appendix E.
To estimate the evacuating employee vehicles, a vehicle occupancy of 1.09 employees per vehicle obtained from the demographic survey (see Appendix F, Subsection F.3.1) was used for the major employers. Table 35 summarizes the employee and vehicle estimates commuting into the EPZ by Zone. Figure 38 and Figure 39 present these data by sector.
3.5      Medical Facilities The data of the medical facilities from previous ETE study were reviewed and retained in this study at the direction of the counties. The capacity data of newly identified medical facilities within the EPZ were provided by the counties or obtained from the Health Resources and Services Administration database4. Since the average number of patients at the medical 3

facilities fluctuates daily, the percent breakdown of ambulatory, wheelchair bound, and bedridden patients from the previous ETE study was used to estimate the number of ambulatory, wheelchair bound and bedridden patients at those newly identified facilities.
Table E3 in Appendix E summarizes the data gathered. Table 36 presents the census of medical facilities in the EPZ. As shown in these tables, a total of 1,071 people have been identified as living in, or being treated in, these facilities.
The transportation requirements for the medical facility population are also presented in Table
: 36. The number and type of evacuating vehicles that need to be provided depend on the patients' state of health. The number of ambulance runs is determined by assuming that 2 patients can be accommodated per ambulance trip; the number of wheelchair bus and van runs assumes 15 and 4 wheelchairs per trip, respectively, and the number of bus runs estimated assumes 30 ambulatory patients per trip.
3.6      Transit Dependent Population The demographic survey (see Appendix F) results were used to estimate the portion of the population requiring transit service:
* Those persons in households that do not have a vehicle available.
* Those persons in households that do have vehicle(s) that would not be available at the time the evacuation is advised.
In the latter group, the vehicle(s) may be used by a commuter(s) who does not return (or is not expected to return) home to evacuate the household.
Table 37 presents estimates of transitdependent people. Note:
* Estimates of persons requiring transit vehicles include schoolchildren. For those evacuation scenarios where children are at school when an evacuation is ordered, separate transportation is provided for the schoolchildren. The actual need for transit vehicles by residents is thereby less than the given estimates. However, estimates of transit vehicles are not reduced when schools are in session.
* It is reasonable and appropriate to consider that many transitdependent persons will evacuate by ridesharing with neighbors, friends or family. For example, nearly 80 percent of those who evacuated from Mississauga, Ontario5 who did not use their own cars, shared a ride with neighbors or friends. Other documents report that approximately 70 percent of transit dependent persons were evacuated via ride sharing. Based on the results of the demographic survey, approximately 72 percent of the transitdependent population will rideshare.
The estimated number of bus trips needed to service transitdependent persons is based on an estimate of average bus occupancy of 30 persons at the conclusion of the bus run. Transit vehicle seating capacities typically equal or exceed 60 children on average (roughly equivalent 5
Institute for Environmental Studies, University of Toronto, THE MISSISSAUGA EVACUATION FINAL REPORT, June 1981. The report indicates that 6,600 people of a transit-dependent population of 8,600 people shared rides with other residents; a ride share rate of 77% (Page 5-10)."

to 40 adults). If transit vehicle evacuees are two thirds adults and one third children, then the number of adult seats taken by 30 persons is 20 + (2/3 x10) = 27. On this basis, the average load factor anticipated is (27/40) x 100 = 68 percent. Thus, if the actual demand for service exceeds the estimates of Table 37 by 50 percent, the demand for service can still be accommodated by the available bus seating capacity.

Table 37 indicates that transportation must be provided for 1,323 people. Therefore, a total of 45 buses are required from a capacity standpoint. In order to service all of the transit dependent population and have at least one bus drive through each of the Zones picking up transit dependent people, 55 buses runs are used in the ETE calculations, (even though only 46 buses are needed from a capacity standpoint). These buses are represented as two vehicles in the ETE simulations due to their larger size and more sluggish operating characteristics.
To illustrate this estimation procedure, we calculate the number of persons, P, requiring public transit or rideshare, and the number of buses, B, required for the MNS EPZ:
: Where, A = Percent of households with commuters C = Percent of households who will not await the return of a commuter 100,720      0.0037 1.00      0.246    1.50 1      0.43 0.49 0.549    2.71  2    0.43 0.49        4,726 1    0.72          30    45 These calculations based on the demographic survey results are explained as follows:
* The number of households (HH) is computed by dividing the EPZ population by the average household size (261,873 ÷ 2.60) and is 100,720.
* All members (1.00 avg.) of households (HH) with no vehicles (0.37%) will evacuate by public transit or rideshare. The term 100,720 x 0.0037 x 1.00, accounts for these people.
* The members of HH with 1 vehicle away (24.6%), who are at home, equal (1.501).
The number of HH where the commuter will not return home is equal to (100,720 x 0.246 x 0.50 x 0.43 x 0.49), as 43% of EPZ households have a commuter, 49% of McGuire Nuclear Station                          36                          KLD Engineering, P.C.

which would not return home in the event of an emergency. The number of persons who will evacuate by public transit or rideshare is equal to the product of these two terms.
* The members of HH with 2 vehicles that are away (54.9%), who are at home, equal (2.71 - 2). The number of HH where neither commuter will return home is equal to 100,720 x 0.549 x 0.71 x (0.43 x 0.49)2. The number of persons who will evacuate by public transit or rideshare is equal to the product of these two terms (the last term is squared to represent the probability that neither commuter will return).
* Households with 3 or more vehicles are assumed to have no need for transit vehicles.
* The total number of persons requiring public transit is the sum of such people in HH with no vehicles, or with 1 or 2 vehicles that are away from home.
The estimate of transitdependent population in Table 37 far exceeds the number of registered transitdependent persons in the EPZ as provided by the counties (discussed below in Section 3.9). This is consistent with the findings of NUREG/CR6953, Volume 2, in that a large majority of the transitdependent population within the EPZs of U.S. nuclear plants does not register with their local emergency response agency.
3.7      Schools, Preschools and Childcare Centers Population Demand Table 38 presents the school, preschool, and childcare center population and transportation requirements for the direct evacuation of all schools within the EPZ for the 20202021 school year. The majority of the information was provided by the local county emergency management agencies. Data from the National Center for Education Statistics6, the North Carolina Division of Child Development and Early Education7, the National Application Center8 ,
and aerial imagery for parking spaces was used where data was missing. The column in Table 38 entitled Buses Required specifies the number of buses required for each school under the following set of assumptions and estimates:
* No students will be picked up by their parents prior to the arrival of the buses.
* While many high school students commute to school using private automobiles (as discussed in Section 2.4 of NUREG/CR7002, Rev. 1), the estimate of buses required for school evacuation does not consider the use of these private vehicles.
* Bus capacity, expressed in students per bus, is set to 70 for elementary schools/childcare centers and 40 for middle and high schools.
* As stated in the MNS 2022 Emergency Preparedness Information9 brochure, for Lincoln County, all childcare facilities will be moved to S. Ray Lowder Elementary school and all private schools not specifically listed will be moved to Lincolnton Middle School. All other childcare facilities in the EPZ will be moved to the reception center for the zone in which that facility is located.

* Those staff members who do not accompany the students will evacuate in their private vehicles.
* No allowance is made for student absenteeism, typically 3 percent daily.
The counties in the EPZ could introduce procedures whereby the schools are contacted prior to the dispatch of buses from the depot to ascertain the current estimate of students to be evacuated. In this way, the number of buses dispatched to the schools will reflect the actual number needed. The need for buses would be reduced by any high school students who have evacuated using private automobiles (if permitted by school authorities). Those buses originally allocated to evacuate schoolchildren that are not needed due to children being picked up by their parents (although they are not advised to do so) can be gainfully assigned to service other facilities or those persons who do not have access to private vehicles or to ridesharing.
School buses are represented as two vehicles in the ETE simulation due to their larger size and more sluggish operating characteristics.
3.7.1 Commuter Colleges There are two college campuses within the EPZ: Davidson College and Central Piedmont Community College at Merancas Campus. Both facilities have commuter students who live within the EPZ and drive to campuses. The enrollment data were obtained from the National Application Center10 (NAC) database, supplemented by the previous ETE study and aerial imagery where the data is missing. The data/information is summarized as follows:
Davidson College:
Located in Zone H, 7.5 miles northeast of MNS.
According to the NAC database (as of June 2021), Davidson College has a total of 1,837 fulltime students and 95% of the students live on campus. As such, there are 1,745 (1,837 x 95%) oncampus students and 92 (1,837 - 1,745) offcampus students.
Based on the data obtained in 2019, approximately 53% of the oncampus students own private vehicles. Thus, 925 (1,745 x 53%) students who live on campus own private vehicles.
The remaining 820 (1,745 - 925) oncampus students without vehicles are considered transit dependent and would rideshare with a fellow classmate or evacuate in buses.
According to the demographic survey, approximately 72% of the transitdependent people would rideshare with a neighbor or friend (see Appendix F, Subsection F.3.1).
As such, 590 (820 x 72%) students would rideshare with a fellow classmate, leaving 230 (820 - 590) students who would be evacuated by buses. Using the capacity of 30 people per bus, the total number of transitdependent buses needed for this college is 8 (230 ÷ 30 = 8, rounded up) or 16 vehicles (1 bus equivalent to 2 passenger vehicles).
It is conservatively assumed that all the 92 offcampus students live within the EPZ and also evacuate in private vehicles. Applying the average number of commuter vehicle occupancy rate (1.09 - see Appendix F, Subsection F.3.1) from demographic survey, there are 84 (92 ÷ 1.09) commuter vehicles.

Evacuation Time Estimate                                                                        Rev. 0
 
In summary, the 1,837 students will be evacuated in 1,009 (925 + 84) private vehicles and 8 buses.
Central Piedmont Community College - Merancas Campus:
Located in Zone F, 6.7 miles eastsoutheast of MNS.
The enrollment data for Merancas Campus is unavailable. Based on the aerial imagery, this campus has a total of 600 parking spaces. Since this college has no campus housing, all the students are considered commuter students. Applying the commuter vehicle occupancy rate of 1.09, the 600 vehicles can transport 654 (600 x 1.09) commuter students.
3.8    Special Event A special event can attract large numbers of transients to the EPZ for short periods of time, creating a temporary surge in demand as per Section 2.5.1 of NUREG/CR7002, Rev. 1. The county and state emergency management agencies were polled regarding potential special events in the EPZ. The potential special event identified by OROs that attracts transients from outside the EPZ include:
Carolina Renaissance Festival- 195,000 attendees (78 weeks)
Christmas in Davidson- 25,000 attendees (3 days)
Rural Hill Scottish Festival and Loch Norman Highland Games- 10,000 to 12,000 attendees ( 3 days)
Symphony in the Park - 8,000 attendees (1 day)
Laketoberfest - 8,000 attendees (1 day)
Based on discussion with Duke Energy and OROs, the Carolina Renaissance Festival was chosen as the special event (Scenario 13) in accordance with NUREG/CR7002, Rev. 1, because it is the single event that attracts the largest number of transients to the EPZ. The special event takes place seven consecutive Saturdays and Sundays in October and November. Exact data on the number of transients present during peak times could not be obtained. Instead, it is assumed the parking lots are full during peak times. Based on the aerial imagery, there is approximately 1,465,100 square feet of parking space for the Carolina Renaissance Festival. Applying a reduction factor of 66% (since every third lane is a travel lane, only about twothirds (2/3) of the space is used for parking), at peak times there is 966,966 square feet of parked vehicles.
Using 176 sq. ft. (22 x 8 per vehicle including spacing between each car) parking area for each car, it is estimated that 5,494 vehicles (966,966/176 = 5,494) are present at peak times. It was assumed that families travel to the event as a household unit in a single vehicle (2.60 people per household). Therefore, the number of attendees present at peak times of the event is approximately 14,284 people (5,494*2.60). Note that this does not include people who use rideshare service (Uber/Lyft etc.) to attend the festival. Based on the data from the previous study, 52% of the festival attendees are not EPZ residents, resulting in an additional 7,428 (14,285*0.52 = 7,428) transients present in the EPZ during the special event that would evacuate in 2,857 vehicles (5,494*0.52 = 2,857). The remainder of the event attendees are already counted within the EPZ permanent resident population. Vehicles were assigned on a link in the linknode analysis network within the festival site.

were generated utilizing the same mobilization distributions as transients. Public transportation is not provided for this event and was therefore not considered in the special event analysis.
3.9    Access and/or Functional Needs Population Based on data provided by the counties, there are an estimated 52 access and/or functional needs people within the Catawba County portion of the EPZ, 93 people within the Gaston County portion of the EPZ, 26 people within the Iredell County portion of the EPZ, 105 people within the Lincoln County portion of the EPZ and 214 people within the Mecklenburg County portion of the EPZ who require transportation assistance to evacuate. Aside from Lincoln and Catawba Counties, details on the number of ambulatory, wheelchairbound and bedridden people were not available. It is assumed that the percentage of ambulatory (72%), wheelchair bound (20%) and bedridden populations (8%) are similar to the percentages used for medical facilities within the EPZ. This results in 334 ambulatory persons that would require a bus to evacuate, 118 wheelchairbound persons that would require a wheelchair bus/van to evacuate and 38 bedridden persons that would require an ambulance to evacuate. A total of 17 buses (capacity of 30 ambulatory persons per bus), 8 wheelchair buses (capacity of 15 wheelchair bound persons per wheelchair bus), 3 wheelchair vans (capacity of 4 wheelchair bound persons per van) and 20 ambulances (capacity 2 bedridden persons per ambulance) for a total number of 48 vehicles are estimated to be needed to evacuate the access and/or functional needs population in a reasonable amount of time.
Table 39 shows the total number of people registered for access and/or functional needs by type of need. The table also estimates the number of transportation resources needed to evacuate these people in a timely manner. Buses and wheelchair buses needed to evacuate the special needs population are represented as two vehicles in the ETE simulations due to their larger size and more sluggish operating characteristics.
3.10 Correctional Facilities As shown in Table E11, there is one correctional facility within the EPZ - Mecklenburg County Sheriff's Office Jail North. The total inmate population at this correctional facility is estimated to be 500 persons. A total of 17 secure vans are available to evacuate this correctional facility. As discussed in item 3f of Section 2.4, it is assumed that vans can accommodate 12 passengers (including 10 inmates and 2 deputies/officers) per van. As such this facility needs 50 secure vans to evacuate.
3.11 External Traffic Vehicles will be traveling through the EPZ (externalexternal trips) at the time of an emergency event. After the Advisory to Evacuate (ATE) is announced, these throughtravelers will also evacuate. These vehicles are assumed to travel on the major routes traversing the study area -
Interstate 85 (I85), I485, and I77. It is assumed that this traffic will continue to enter the EPZ during the first 120 minutes following the ATE .

Evacuation Time Estimate                                                                          Rev. 0
 
Average Annual Daily Traffic (AADT) data from 2019 was obtained from North Carolina Department of Transportations website11 to estimate the number of vehicles per hour on the aforementioned routes. The 2020 AADT data was available, but it was not used in this study due to the significant decrease in traffic on these highways caused by the COVID19 pandemic.
The 2019 AADT was multiplied by the KFactor, which is the proportion of the AADT on a roadway segment or link during the design hour, resulting in the Design Hour Volume (DHV).
The design hour is usually the 30th highest hourly traffic volume of the year, measured in vehicles per hour (vph). The DHV is then multiplied by the DFactor, which is the proportion of the DHV occurring in the peak direction of travel (also known as the directional split). The resulting values are the directional design hourly volumes (DDHV) and are presented in Table 3 10, for each of the routes considered. The DDHV is then multiplied by 2 hours (security road blocks - SRB - are assumed to be activated at 120 minutes after the ATE ) to estimate the total number of external vehicles loaded on the analysis network. As indicated, there are 52,126 vehicles entering the EPZ as externalexternal trips prior to the activation of the SRB and the diversion of this traffic. This number is reduced by 60% for evening scenarios (Scenarios 5 and
: 12) as discussed in Section 6.
3.12        Background Traffic Section 5 discusses the time needed for the people in the EPZ to mobilize and begin their evacuation trips. As shown in Table 59, there are 14 time periods during which traffic is loaded on to roadways in the study area to model the mobilization time of people in the EPZ. Note, there is no traffic generated during the 15th time period, as this time period is intended to allow traffic that has already begun evacuating to clear the study area boundaries.
This study does not assume that roadways are empty at the start of Time Period 1. Rather, there is an initialization time period (often referred to as fill time in traffic simulation) wherein the traffic volumes from Time Period 1 are loaded onto roadways in the study area.
The amount of initialization/fill traffic that is on the roadways in the study area at the start of Time Period 1 depends on the scenario and the region being evacuated (see Section 6). There are 16,082 vehicles on the roadways in the study area at the end of fill time for an evacuation of the entire EPZ (Region R03) under Scenario 1 (summer, midweek, midday, good weather) conditions.
3.13 Summary of Demand A summary of population and vehicle demand is provided in Table 311 and Table 312, respectively. This summary includes all population groups described in this section. A total of 448,089 people and 264,412 vehicles are considered in this study.

95% of the total students (1,837) live in the dorms. 925 on-campus students use personal vehicles to evacuate. Based on the demographic survey, it was assumed that 72% of the students will rideshare with a friend. 206 students will need buses to evacuate.
Alexander Graham Middle School is located outside of the study area. According to the Mecklenburg County Radiological Emergency Response (REP) Plans, this school will be evacuated by county school buses.
      ~
As per 2017 Gaston County REP Plan for the McGuire and Catawba Nuclear Stations, private schools and daycare centers are primarily responsible for providing needed transportation for children, students, and staff.
As per 2018 Lincoln County Standard Operation Guideline (SOG), pick-up by parents is discouraged at the schools and pre-schools.
But if parents arrive to pick-up the children school administration will coordinate with the responding parents. One staff member accompanies the children on the vehicles/buses and stay with the children until dismissed to parents/guardians at the relocation school.
Kids in Motion is located in the Shadow Region but near the 10-mile EPZ boundary. As per the Lincoln County REP Plan, this facility will evacuate to reception center in the event of an emergency.
According to the 2017 Mecklenburg County REP Plans, each private school and day care facility will provide their own transportation in the form of private vehicles, buses, and vans.

4    ESTIMATION OF HIGHWAY CAPACITY The ability of the road network to service vehicle demand is a major factor in determining how rapidly an evacuation can be completed. The capacity of a road is defined as the maximum hourly rate at which persons or vehicles can reasonably be expected to traverse a point or uniform section of a lane of roadway during a given time period under prevailing roadway, traffic, and control conditions, as stated in the 2016 Highway Capacity Manual (HCM 2016). This section discusses how the capacity of the roadway network was estimated.
In discussing capacity, different operating conditions have been assigned alphabetical designations, A through F, to reflect the range of traffic operational characteristics. These designations have been termed "Levels of Service" (LOS). For example, LOS A connotes freeflow and highspeed operating conditions; LOS F represents a forced flow condition. LOS E describes traffic operating at or near capacity.
Another concept, closely associated with capacity, is Service Volume. Service volume (SV) is defined as The maximum hourly rate at which vehicles, bicycles or persons reasonably can be expected to traverse a point or uniform section of a roadway during an hour under specific assumed conditions while maintaining a designated level of service. This definition is similar to that for capacity. The major distinction is that values of SV vary from one LOS to another, while capacity is the SV at the upper bound of LOS E, only.
Thus, in simple terms, SV is the maximum traffic that can travel on a road and still maintain a certain perceived level of quality to a driver based on the A, B, C, rating system (LOS). Any additional vehicles above the SV would drop the rating to a lower letter grade.
This distinction is illustrated in Exhibit 1237 of the HCM 2016. As indicated there, the SV varies with Free Flow Speed (FFS), and LOS. The SV is calculated by the DYNEV II simulation model, based on the specified link attributes, FFS, capacity, control device and traffic demand.
Other factors also influence capacity. These include, but are not limited to:
Lane width Shoulder width Pavement condition Horizontal and vertical alignment (curvature and grade)
Percent truck traffic Control device (and timing if it is a signal)
Weather conditions (good, rain, ice)
These factors are considered during the road survey and in the capacity estimation process; some factors have greater influence on capacity than others. For example, lane and shoulder width have only a limited influence on Base Free Flow Speed (BFFS1) according to Exhibit 157 of the HCM 2016. Consequently, lane and shoulder widths at the narrowest points were observed during the road survey and these observations were recorded, but no detailed 1
A very rough estimate of BFFS might be taken as the posted speed limit plus 10 mph (HCM 2016 Page 15-15).

measurements of lane or shoulder width were taken. Horizontal and vertical alignment can influence both FFS and capacity. The estimated FFS were measured using the survey vehicles speedometer and observing local traffic, under free flow conditions. Free flow speeds ranged from 10 to 75 mph in the study area. Capacity is estimated from the procedures of the HCM 2016. For example, HCM 2016 Exhibit 71(b) shows the sensitivity of SV at the upper bound of LOS D to grade (capacity is the SV at the upper bound of LOS E).
The amount of traffic that can flow on a roadway is effectively governed by vehicle speed and spacing. The faster that vehicles can travel when closely spaced, the higher the amount of flow.
As discussed in Section 2.6, it is necessary to adjust capacity figures to represent the prevailing conditions. Adverse conditions like inclement weather, construction, and other incidents tend to slow traffic down and often, also increase vehicletovehicles separation, thus decreasing the amount of traffic flow. Based on limited empirical data, conditions such as rain reduce the values of freeflow speed and of highway capacity by approximately 10 percent. Over the last decade new studies have been made on the effects of rain on traffic capacity. These studies indicate a range of effects between 5 and 20 percent depending on wind speed and precipitation rates. As indicated in Section 2.6, we employ, a reduction in free speed and in highway capacity of 10 percent and 20 percent for rain and ice, respectively.
Since congestion arising from evacuation may be significant, estimates of roadway capacity must be determined with great care. Because of its importance, a brief discussion of the major factors that influence highway capacity is presented in this section.
Rural highways generally consist of: (1) one or more uniform sections with limited access (driveways, parking areas) characterized by uninterrupted flow; and (2) approaches to at grade intersections where flow can be interrupted by a control device or by turning or crossing traffic at the intersection. Due to these differences, separate estimates of capacity must be made for each section. Often, the approach to the intersection is widened by the addition of one or more lanes (turn pockets or turn bays), to compensate for the lower capacity of the approach due to the factors there that can interrupt the flow of traffic. These additional lanes are recorded during the field survey and later entered as input to the DYNEV II system.
4.1    Capacity Estimations on Approaches to Intersections Atgrade intersections are apt to become the first bottleneck locations under local heavy traffic volume conditions. This characteristic reflects the need to allocate access time to the respective competing traffic streams by exerting some form of control. During evacuation, control at critical intersections will often be provided by traffic control personnel assigned for that purpose, whose directions may supersede traffic control devices. See Appendix G for more information.

Evacuation Time Estimate                                                                      Rev. 0
 
The perlane capacity of an approach to a signalized intersection can be expressed (simplistically) in the following form:
3600                    3600 where:
Qcap,m          =      Capacity of a single lane of traffic on an approach, which executes movement, m, upon entering the intersection; vehicles per hour (vph) hm              =      Mean queue discharge headway of vehicles on this lane that are executing movement, m; seconds per vehicle G              =      Mean duration of GREEN time servicing vehicles that are executing movement, m, for each signal cycle; seconds L              =      Mean "lost time" for each signal phase servicing movement, m; seconds C              =      Duration of each signal cycle; seconds Pm              =      Proportion of GREEN time allocated for vehicles executing movement, m, from this lane. This value is specified as part of the control treatment.
m              =      The movement executed by vehicles after they enter the intersection: through, leftturn, rightturn, and diagonal.
The turnmovementspecific mean discharge headway hm, depends in a complex way upon many factors: roadway geometrics, turn percentages, the extent of conflicting traffic streams, the control treatment, and others. A primary factor is the value of "saturation queue discharge headway", hsat, which applies to through vehicles that are not impeded by other conflicting traffic streams. This value, itself, depends upon many factors including motorist behavior.
Formally, we can write, where:
hsat            =      Saturation discharge headway for through vehicles; seconds per vehicle F1,F2          =      The various known factors influencing hm fm( )          =      Complex function relating hm to the known (or estimated) values of hsat, F1, F2, McGuire Nuclear Station                          43                              KLD Engineering, P.C.
Evacuation Time Estimate                                                                          Rev. 0
 
The estimation of hm for specified values of hsat, F1, F2, ... is undertaken within the DYNEV II simulation model by a mathematical model2. The resulting values for hm always satisfy the condition:
That is, the turnmovementspecific discharge headways are always greater than, or equal to the saturation discharge headway for through vehicles. These headways (or its inverse equivalent, saturation flow rate), may be determined by observation or using the procedures of the HCM 2016.
The above discussion is necessarily brief given the scope of this Evacuation Time Estimate (ETE) report and the complexity of the subject of intersection capacity. In fact, Chapters 19, 20 and 21 in the HCM 2016 address this topic. The factors, F1, F2, , influencing saturation flow rate are identified in equation (198) of the HCM 2016.
The traffic signals within the EPZ and Shadow Region are modeled using representative phasing plans and phase durations obtained as part of the field data collection. Traffic responsive signal installations allow the proportion of green time allocated (Pm) for each approach to each intersection, to be determined by the expected traffic volumes on each approach during evacuation circumstances. The amount of green time (G) allocated is subject to maximum and minimum phase duration constraints; 2 seconds of yellow time are indicated for each signal phase and 1 second of allred time is assigned between signal phases, typically. If a signal is pre timed, the yellow and allred times observed during the road survey are used. A lost time (L) of 2.0 seconds is used for each signal phase in the analysis.
4.2    Capacity Estimation along Sections of Highway The capacity of highway sections  as distinct from approaches to intersections  is a function of roadway geometrics, traffic composition (e.g., percent heavy trucks and buses in the traffic stream) and, of course, motorist behavior. There is a fundamental relationship which relates SV (i.e., the number of vehicles serviced within a uniform highway section in a given time period) to traffic density. The top curve in Figure 41 illustrates this relationship.
As indicated, there are two flow regimes: (1) Free Flow (left side of curve); and (2) Forced Flow (right side). In the Free Flow regime, the traffic demand is fully serviced; the SV increases as demand volume and density increase, until the SV attains its maximum value, which is the capacity of the highway section. As traffic demand and the resulting highway density increase beyond this "critical" value, the rate at which traffic can be serviced (i.e., the SV) can actually decline below capacity (capacity drop). Therefore, in order to realistically represent traffic performance during congested conditions (i.e., when demand exceeds capacity), it is necessary to estimate the service volume, VF, under congested conditions.

The value of VF can be expressed as:
where:
R                =        Reduction factor which is less than unity We have employed a value of R=0.90. The advisability of such a capacity reduction factor is based upon empirical studies that identified a falloff in the service flow rate when congestion occurs at bottlenecks or choke points on a freeway system. Zhang and Levinson3 describe a research program that collected data from a computerbased surveillance system (loop detectors) installed on the Interstate Highway System, at 27 active bottlenecks in the twin cities metro area in Minnesota over a 7week period. When flow breakdown occurs, queues are formed which discharge at lower flow rates than the maximum capacity prior to observed breakdown. These queue discharge flow (QDF) rates vary from one location to the next and vary by day of week and time of day based upon local circumstances. The cited reference presents a mean QDF of 2,016 passenger cars per hour per lane (pcphpl). This figure compares with the nominal capacity estimate of 2,250 pcphpl estimated for the ETE. The ratio of these two numbers is 0.896 which translates into a capacity reduction factor of 0.90.
Since the principal objective of ETE analyses is to develop a realistic estimate of evacuation times, use of the representative value for this capacity reduction factor (R=0.90) is justified. This factor is applied only when flow breaks down, as determined by the simulation model.
Rural roads, like freeways, are classified as uninterrupted flow facilities. (This is in contrast with urban street systems which have closely spaced signalized intersections and are classified as interrupted flow facilities.) As such, traffic flow along rural roads is subject to the same effects as freeways in the event traffic demand exceeds the nominal capacity, resulting in queuing and lower QDF rates. As a practical matter, rural roads rarely break down at locations away from intersections. Any breakdowns on rural roads are generally experienced at intersections where other model logic applies, or at lane drops which reduce capacity there.
Therefore, the application of a factor of 0.90 is appropriate on rural roads, but rarely, if ever, activated.
The estimated value of capacity is based primarily upon the type of facility and on roadway geometrics. Sections of roadway with adverse geometrics are characterized by lower freeflow speeds and lane capacity. Exhibit 1546 in the HCM 2016 was referenced to estimate saturation flow rates. The impact of narrow lanes and shoulders on freeflow speed and on capacity is not material, particularly when flow is predominantly in one direction as is the case during an evacuation.
The procedure used here was to estimate "section" capacity, VE, based on observations made traveling over each section of the evacuation network, based on the posted speed limits and travel behavior of other motorists and by reference to the HCM 2016. The DYNEV II simulation model determines for each highway section, represented as a network link, whether its 3

capacity would be limited by the "sectionspecific" service volume, VE, or by the intersectionspecific capacity. For each link, the model selects the lower value of capacity.
4.3  Application to the MNS Study Area As part of the development of the linknode analysis network for the study area, an estimate of roadway capacity is required. The source material for the capacity estimates presented herein is contained in:
2016 Highway Capacity Manual (HCM 2016)
Transportation Research Board National Research Council Washington, D.C.
The highway system in the study area consists primarily of three categories of roads and, of course, intersections:
TwoLane roads: Local, State Multilane Highways (atgrade)
Freeways Each of these classifications will be discussed.
4.3.1 TwoLane Roads Ref: HCM 2016 Chapter 15 Two lane roads comprise the majority of highways within the study area. The perlane capacity of a twolane highway is estimated at 1,700 passenger cars per hour (pc/h). This estimate is essentially independent of the directional distribution of traffic volume except that, for extended distances, the twoway capacity will not exceed 3,200 pc/h. The HCM 2016 procedures then estimate LOS and Average Travel Speed. The DYNEV II simulation model accepts the specified value of capacity as input and computes average speed based on the timevarying demand: capacity relations.
Based on the field survey and on expected traffic operations associated with evacuation scenarios:
Most sections of twolane roads within the study area are classified as Class I, with "level terrain"; some are rolling terrain.
Class II highways are mostly those within urban and suburban centers.
4.3.2 Multilane Highway Ref: HCM 2016 Chapter 12 Exhibit 128 of the HCM 2016 presents a set of curves that indicate a perlane capacity ranging from approximately 1,900 to 2,300 pc/h, for freespeeds of 45 to 70 mph, respectively. Based on observation, the multilane highways outside of urban areas within the study area, service McGuire Nuclear Station                          46                            KLD Engineering, P.C.
Evacuation Time Estimate                                                                      Rev. 0
 
traffic with freespeeds in this range. The actual timevarying speeds computed by the simulation model reflect the demand and capacity relationship and the impact of control at intersections. A conservative estimate of perlane capacity of 1,900 pc/h is adopted for this study for multilane highways outside of urban areas.
4.3.3 Freeways Ref: HCM 2016 Chapters 10, 12, 13, 14 Chapter 10 of the HCM 2016 describes a procedure for integrating the results obtained in Chapters 12, 13 and 14, which compute capacity and LOS for freeway components. Chapter 10 also presents a discussion of simulation models. The DYNEV II simulation model automatically performs this integration process.
Chapter 12 of the HCM 2016 presents procedures for estimating capacity and LOS for Basic Freeway Segments". Exhibit 1237 of the HCM 2016 presents capacity vs. free speed estimates, which are provided below.
Free Speed (mph):                  55      60      65      70+
PerLane Capacity (pc/h):        2,250    2,300    2,350    2,400 The inputs to the simulation model are highway geometrics, freespeeds and capacity based on field observations. The simulation logic calculates actual timevarying speeds based on demand:
capacity relationships. A conservative estimate of perlane capacity of 2,250 pc/h is adopted for this study for freeways.
Chapter 13 of the HCM 2016 presents procedures for estimating capacity, speed, density, and LOS for freeway weaving sections. The simulation model contains logic that relates speed to demand volume: capacity ratio. The value of capacity obtained from the computational procedures detailed in Chapter 13 depends on the "Type" and geometrics of the weaving segment and on the "Volume Ratio" (ratio of weaving volume to total volume).
Chapter 14 of the HCM 2016 presents procedures for estimating capacities of ramps and of "merge" areas. There are three significant factors to the determination of capacity of a ramp freeway junction: The capacity of the freeway immediately downstream of an onramp or immediately upstream of an offramp; the capacity of the ramp roadway; and the maximum flow rate entering the ramp influence area. In most cases, the freeway capacity is the controlling factor. Values of this merge area capacity are presented in Exhibit 1410 of the HCM 2016 and depend on the number of freeway lanes and on the freeway free speed. Ramp capacity is presented in Exhibit 1412 and is a function of the ramp FFS. The DYNEV II simulation model logic simulates the merging operations of the ramp and freeway traffic in accord with the procedures in Chapter 14 of the HCM 2016. If congestion results from an excess of demand relative to capacity, then the model allocates service appropriately to the two entering traffic streams and produces LOS F conditions (The HCM 2016 does not address LOS F explicitly).

4.3.4 Intersections Ref: HCM 2016 Chapters 19, 20, 21, 22 Procedures for estimating capacity and LOS for approaches to intersections are presented in Chapter 19 (signalized intersections), Chapters 20, 21 (unsignalized intersections) and Chapter 22 (roundabouts). The complexity of these computations is indicated by the aggregate length of these chapters. The DYNEV II simulation logic is likewise complex.
The simulation model explicitly models intersections: Stop/yield controlled intersections (both 2way and allway) and traffic signal controlled intersections. Where intersections are controlled by fixed time controllers, traffic signal timings are set to reflect average (non evacuation) traffic conditions. Actuated traffic signal settings respond to the timevarying demands of evacuation traffic to adjust the relative capacities of the competing intersection approaches.
The model is also capable of modeling the presence of manned traffic control. At specific locations where it is advisable or where existing plans call for overriding existing traffic control to implement manned control, the model will use actuated signal timings that reflect the presence of traffic guides. At locations where a special traffic control strategy (continuous left turns, contraflow lanes) is used, the strategy is modeled explicitly. A list that includes the total number of intersections modeled that are unsignalized, signalized, or manned by response personnel is noted in Appendix K.
4.4  Simulation and Capacity Estimation Chapter 6 of the HCM 2016 is entitled, HCM and Alternative Analysis Tools. The chapter discusses the use of alternative tools such as simulation modeling to evaluate the operational performance of highway networks. Among the reasons cited in Chapter 6 to consider using simulation as an alternative analysis tool is:
The system under study involves a group of different facilities or travel modes with mutual interactions involving several HCM chapters. Alternative tools are able to analyze these facilities as a single system.
This statement succinctly describes the analyses required to determine traffic operations across an area encompassing a study area operating under evacuation conditions. The model utilized for this study, DYNEV II is further described in Appendix C. It is essential to recognize that simulation models do not replicate the methodology and procedures of the HCM 2016- they replace these procedures by describing the complex interactions of traffic flow and computing Measures of Effectiveness (MOE) detailing the operational performance of traffic over time and by location. The DYNEV II simulation model includes some HCM 2016 procedures only for the purpose of estimating capacity.
All simulation models must be calibrated properly with field observations that quantify the performance parameters applicable to the analysis network. Two of the most important of these are: (1) FFS; and (2) saturation headway, hsat. The first of these is estimated by direct McGuire Nuclear Station                          48                              KLD Engineering, P.C.
Evacuation Time Estimate                                                                        Rev. 0
 
observation during the road survey; the second is estimated using the concepts of the HCM 2016, as described earlier.
It is important to note that simulation represents a mathematical representation of an assumed set of conditions using the best available knowledge and understanding of traffic flow and available inputs. Simulation should not be assumed to be a prediction of what will happen under any event because a real evacuation can be impacted by an infinite number of things -
many of which will differ from these test cases - and many others cannot be taken into account with the tools available.
4.5    Boundary Conditions As illustrated in Figure 12 and in Appendix K, the linknode analysis network used for this study is finite. The analysis network extends well beyond the 15mile radial study area in some locations in order to model intersections with other major evacuation routes beyond the study area. However, the network does have an end at the destination (exit) nodes as discussed in Appendix C. Beyond these destination nodes, there may be signalized intersections or merge points that impact the capacity of the evacuation routes leaving the study area. Rather than neglect these boundary conditions, this study assumes a 25% reduction in capacity on two lane roads (Section 4.3.1 above) and multilane highways (Section 4.3.2 above). There is no reduction in capacity for freeways due to boundary conditions. The 25% reduction in capacity is based on the prevalence of actuated traffic signals in the study area and the fact that the evacuating traffic volume will be more significant than the competing traffic volume at any downstream signalized intersections, thereby warranting a more significant percentage (75% in this case) of the signal green time.

5    ESTIMATION OF TRIP GENERATION TIME Federal guidance (see NUREG/CR7002) specify that the planner estimate the distributions of elapsed times associated with mobilization activities undertaken by the public to prepare for the evacuation trip. The elapsed time associated with each activity is represented as a statistical distribution reflecting differences between members of the public. The quantification of these activitybased distributions relies largely on the results of the demographic survey. We define the sum of these distributions of elapsed times as the Trip Generation Time Distribution.
 
===5.1    Background===
In general, an accident at a nuclear power plant is characterized by the following Emergency Classification Levels (see Section C of Part IV of Appendix E of 10 CFR 50 for details):
: 1. Unusual Event
: 2. Alert
: 3. Site Area Emergency
: 4. General Emergency At each level, the Federal guidelines specify a set of Actions to be undertaken by the Licensee and by the State and Local offsite authorities. As a Planning Basis, we will adopt a conservative posture, in accordance with Section 1.2 of NUREG/CR7002 Rev. 1., that a rapidly escalating accident at the plant wherein evacuation is ordered promptly and no early protective actions have been implemented will be considered in calculating the Trip Generation Time. We will assume:
: 1. The Advisory to Evacuate (ATE) will be announced coincident with the siren notification.
: 2. Mobilization of the general population will commence within 15 minutes after the siren notification.
: 3. ETE are measured relative to the ATE.
We emphasize that the adoption of this planning basis is not a representation that these events will occur within the indicated time frame. Rather, these assumptions are necessary in order to:
: 1. Establish a temporal framework for estimating the Trip Generation distribution in the format recommended in Section 2.13 of NUREG/CR6863.
: 2. Identify temporal points of reference that uniquely define "Clear Time" and ETE.
It is likely that a longer time will elapse between the various classes of an emergency. For example, suppose one hour elapses from the siren alert to the ATE. In this case, it is reasonable to expect some degree of spontaneous evacuation by the public during this onehour period. As a result, the population within the EPZ will be lower when the ATE is announced, than at the time of the siren alert. In addition, many will engage in preparation activities to evacuate, in anticipation that an Advisory will be broadcast. Thus, the time needed to complete the mobilization activities and the number of people remaining to evacuate the EPZ after the ATE, will both be somewhat less than the estimates presented in this report. Consequently, the ETE McGuire Nuclear Station                            51                            KLD Engineering, P.C.
Evacuation Time Estimate                                                                          Rev. 0
 
presented in this report are higher than the actual evacuation time, if this hypothetical situation were to take place.
The notification process consists of two events:
: 1. Transmitting information using the alert and notification systems (ANS) available within the EPZ (e.g. sirens, tone alerts, EAS broadcasts, loud speakers).
: 2. Receiving and correctly interpreting the information that is transmitted.
The population within the EPZ is dispersed over an area of 314 square miles and is engaged in a wide variety of activities. It must be anticipated that some time will elapse between the transmission and receipt of the information advising the public of an accident.
The amount of elapsed time will vary from one individual to the next depending on where that person is, what that person is doing, and related factors. Furthermore, some persons who will be directly involved with the evacuation process may be outside the EPZ at the time the emergency is declared. These people may be commuters, shoppers and other travelers who reside within the EPZ and who will return to join the other household members upon receiving notification of an emergency.
As indicated in Section 2.13 of NUREG/CR6863, the estimated elapsed times for the receipt of notification can be expressed as a distribution reflecting the different notification times for different people within, and outside, the EPZ. By using time distributions, it is also possible to distinguish between different population groups and different dayofweek and timeofday scenarios, so that accurate ETE may be computed.
For example, people at home or at work within the EPZ will be notified by siren, and/or tone alert and/or radio (if available). Those well outside the EPZ will be notified by telephone, radio, TV and wordofmouth, with potentially longer time lags. Furthermore, the spatial distribution of the EPZ population will differ with time of day - families will be united in the evenings but dispersed during the day. In this respect, weekends will differ from weekdays.
As indicated in Section 4.3 of NUREG/CR7002, Rev. 1, the information required to compute trip generation times is typically obtained from a demographic survey of EPZ residents. Such a demographic survey was conducted in support of this ETE study. Appendix F discusses the demographic survey sampling plan, documents the survey instrument utilized, and provides the survey results. It is important to note that the shape and duration of the evacuation trip mobilization distribution is important at sites where traffic congestion is not expected to cause the evacuation time estimate to extend in time well beyond the trip generation period. The remaining discussion will focus on the application of the trip generation data obtained from the demographic survey to the development of the ETE documented in this report.
5.2    Fundamental Considerations The environment leading up to the time that people begin their evacuation trips consists of a sequence of events and activities. Each event (other than the first) occurs at an instant in time and is the outcome of an activity.

Activities are undertaken over a period of time. Activities may be in "series" (i.e., to undertake an activity implies the completion of all preceding events) or may be in parallel (two or more activities may take place over the same period of time). Activities conducted in series are functionally dependent on the completion of prior activities; activities conducted in parallel are functionally independent of one another. The relevant events associated with the public's preparation for evacuation are:
Event Number        Event Description 1            Notification 2            Awareness of Situation 3            Depart Work 4            Arrive Home 5            Depart on Evacuation Trip Associated with each sequence of events are one or more activities, as outlined in Table 51:
These relationships are shown graphically in Figure 51.
An Event is a state that exists at a point in time (e.g., depart work, arrive home)
An Activity is a process that takes place over some elapsed time (e.g., prepare to leave work, travel home)
As such, a completed Activity changes the state of an individual (i.e., the activity, travel home changes the state from depart work to arrive home). Therefore, an Activity can be described as an Event Sequence; the elapsed times to perform an event sequence vary from one person to the next and are described as statistical distributions on the following pages.
An employee who lives outside the EPZ will follow sequence (c) of Figure 5 1. A household within the EPZ that has one or more commuters at work, and will await their return before beginning the evacuation trip will follow the first sequence of Table 51 (a). A household within the EPZ that has no commuters at work, or that will not await the return of any commuters, will follow the second sequence of Figure 51(a), regardless of day of week or time of day.
Households with no commuters on weekends or in the evening/nighttime will follow the applicable sequence in Figure 51 (b). Transients will always follow one of the sequences of Figure 51(b). Some transients away from their residence (lodging facility or campground) could elect to evacuate immediately without returning to the residence, as indicated in the second sequence.
It is seen from Figure 51, that the Trip Generation time (the total elapsed time from Event 1 to Event 5) depends on the scenario and will vary from one household to the next. Furthermore, Event 5 depends, in a complicated way, on the time distributions of all activities preceding that event. That is, to estimate the time distribution of Event 5, we must obtain estimates of the time distributions of all preceding events. For this study, we adopt the conservative posture that all activities will occur in sequence.
In some cases, assuming certain events occur strictly sequential (for instance, commuter returning home before beginning preparation to leave) can result in rather conservative (that is, McGuire Nuclear Station                              53                              KLD Engineering, P.C.

longer) estimates of mobilization times. It is reasonable to expect that at least some parts of these events will overlap for many households, but that assumption is not made in this study.
5.3    Estimated Time Distributions of Activities Preceding Event 5 The time distribution of an event is obtained by "summing" the time distributions of all prior contributing activities. (This "summing" process is quite different than an algebraic sum since it is performed on distributions - not scalar numbers).
Time Distribution No. 1, Notification Process: Activity 1  2 Federal regulations (10CFR50 Appendix E, Item IV.D.3) stipulate, [t]he design objective of the prompt public alert and notification system shall be to have the capability to essentially complete the initial alerting and initiate notification of the public within the plume exposure pathway EPZ within about 15 minutes. Furthermore, Federal Emergency Management Agency (FEMA)
Radiological Emergency Preparedness Program Manual Part V Section B.1 Bullet 3 states that Notification methods will be established to ensure coverage within 45 minutes of essentially 100%
of the population within the entire plume exposure pathway EPZ who may not have received the initial notification .
Given the federal regulations and guidance, and the presence of sirens within the EPZ, it is assumed that 87 percent of those within the EPZ will be aware of the accident within 30 minutes with the remainder notified within the following 15 minutes. The assumed distribution for notifying the EPZ population is provided in Table 52. The distribution is plotted in Figure 52.
Distribution No. 2, Prepare to Leave Work: Activity 2  3 It is reasonable to expect that the vast majority of business enterprises within the EPZ will elect to shut down following notification and most employees would leave work quickly. Commuters, who work outside the EPZ could, in all probability, also leave quickly since facilities outside the EPZ would remain open and other personnel would remain. Personnel or farmers responsible for equipment/livestock would require additional time to secure their facility. The distribution of Activity 2  3 shown in Table 53 reflects data obtained by the demographic survey for employees working inside or outside of the EPZ who returns home prior to evacuating. This distribution is also applicable for residents to leave stores, restaurants, parks, and other locations within the EPZ. This distribution is plotted in Figure 52.
Distribution No. 3, Travel Home: Activity 3  4 These data are provided directly by those households which responded to the demographic survey. This distribution is plotted in Figure 52 and listed in Table 54.
Distribution No. 4, Prepare to Leave Home:      Activity 2, 4  5 These data are provided directly by those households which responded to the demographic survey. This distribution is plotted in Figure 52 and listed in Table 55.

Distribution No. 5, Ice Clearance Time Distribution Inclement weather scenarios involving ice must address the time lags associated with ice clearance. It is assumed that light snow/ice cleaning equipment is mobilized and deployed during the light snowfall or icy conditions to maintain passable roads. The general consensus is that the light snow/ice cleaning efforts are generally successful for all but the most extreme blizzards when the rate of snow accumulation exceeds that of snow clearance over a period of many hours (Note - evacuation may not be a prudent protective action under such blizzard conditions).
Consequently, it is reasonable to assume that the highway system will remain passable - albeit at a lower capacity - under the vast majority of ice conditions. Nevertheless, for the vehicles to gain access to the highway system, it may be necessary for driveways and employee parking lots to be cleared to the extent needed to permit vehicles to gain access to the roadways. These clearance activities take time; this time must be incorporated into the trip generation time distributions. This distribution is plotted in Figure 52 and listed in Table 56.
Note that those respondents (8.6%) who answered that they would not take time to clear their driveway were assumed to be ready immediately at the start of this activity. Essentially, they would drive through the light snow/ice on the driveway to access the roadway and begin their evacuation trip.
5.4    Calculation of Trip Generation Time Distribution The time distributions for each of the mobilization activities presented herein must be combined to form the appropriate Trip Generation Distributions. As discussed above, this study assumes that the stated events take place in sequence such that all preceding events must be completed before the current event can occur. For example, if a household awaits the return of a commuter, the worktohome trip (Activity 3  4) must precede Activity 4  5.
To calculate the time distribution of an event that is dependent on two sequential activities, it is necessary to sum the distributions associated with these prior activities. The distribution summing algorithm is applied repeatedly as shown to form the required distribution. As an outcome of this procedure, new time distributions are formed; we assign letter designations to these intermediate distributions to describe the procedure. Table 57 presents the summing procedure to arrive at each designated distribution.
Table 58 presents a description of each of the final trip generation distributions achieved after the summing process is completed.
5.4.1 Statistical Outliers As already mentioned, some portion of the survey respondents answer dont know to some questions or choose to not respond to a question. The mobilization activity distributions are based upon actual responses. But, it is the nature of surveys that a few numeric responses are inconsistent with the overall pattern of results. An example would be a case in which for 500 responses, almost all of them estimate less than two hours for a given answer, but 3 say four hours and 4 say six or more hours.
McGuire Nuclear Station                            55                              KLD Engineering, P.C.
Evacuation Time Estimate                                                                          Rev. 0
 
These outliers must be considered: are they valid responses, or so atypical that they should be dropped from the sample?
In assessing outliers, there are three alternatives to consider:
: 1) Some responses with very long times may be valid, but reflect the reality that the respondent really needs to be classified in a different population subgroup, based upon access and/or functional needs;
: 2) Other responses may be unrealistic (6 hours to return home from commuting distance, or 2 days to prepare the home for departure);
: 3) Some high values are representative and plausible, and one must not cut them as part of the consideration of outliers.
The issue of course is how to make the decision that a given response or set of responses are to be considered outliers for the component mobilization activities, using a method that objectively quantifies the process.
There is considerable statistical literature on the identification and treatment of outliers singly or in groups, much of which assumes the data is normally distributed and some of which uses non parametric methods to avoid that assumption. The literature cites that limited work has been done directly on outliers in sample survey responses.
In establishing the overall mobilization time/trip generation distributions, the following principles are used:
: 1) It is recognized that the overall trip generation distributions are conservative estimates, because they assume a household will do the mobilization activities sequentially, with no overlap of activities;
: 2) The individual mobilization activities (prepare to leave work, travel home, prepare home, clear light snow/ice) are reviewed for outliers, and then the overall trip generation distributions are created (see Table 51, Table 57, Table 58);
: 3) Outliers can be eliminated either because the response reflects a special population (e.g.
access and/or functional needs, transit dependent) or lack of realism, because the purpose is to estimate trip generation patterns for personal vehicles;
: 4) To eliminate outliers, a) the mean and standard deviation of the specific activity are estimated from the responses, b) the median of the same data is estimated, with its position relative to the mean noted, c) the histogram of the data is inspected, and d) all values greater than 3 standard deviations are flagged for attention, taking special note of whether there are gaps (categories with zero entries) in the histogram display.
In general, only flagged values more than 3.5 standard deviations from the mean are allowed to be considered outliers, with gaps in the histogram expected.

Evacuation Time Estimate                                                                          Rev. 0
 
When flagged values are classified as outliers and dropped, steps a to d are repeated.
: 5) As a practical matter, even with outliers eliminated by the above, the resultant histogram, viewed as a cumulative distribution, is not a normal distribution. A typical situation that results is shown below in Figure 53.
: 6) In particular, the cumulative distribution differs from the normal distribution in two key aspects, both very important in loading a network to estimate evacuation times:
Most of the real data is to the left of the normal curve above, indicating that the network loads faster for the first 8085 percent of the vehicles, potentially causing more (and earlier) congestion than otherwise modeled; The last 1015 percent of the real data tails off slower than the comparable normal curve, indicating that there is significant traffic still loading at later times.
Because these two features are important to preserve, it is the histogram of the data that is used to describe the mobilization activities, not a normal curve fit to the data. One could consider other distributions, but using the shape of the actual data curve is unambiguous and preserves these important features;
: 7) With the mobilization activities each modeled according to Steps 16, including preserving the features cited in Step 6, the overall (or total) mobilization times are constructed.
This is done by using the data sets and distributions under different scenarios (e.g., commuter returning, no commuter returning in each). In general, these are additive, using weighting based upon the probability distributions of each element; Figure 54 presents the combined trip generation distributions for each population group considered. These distributions are presented on the same time scale. (As discussed earlier, the use of strictly additive activities is a conservative approach, because it makes all activities sequential - preparation for departure follows the return of the commuter, and so forth. In practice, it is reasonable that some of these activities are done in parallel, at least to some extent - for instance, preparation to depart begins by a household member at home while the commuter is still on the road.)
The mobilization distributions that result are used in their tabular/graphical form as direct inputs to later computations that lead to the ETE.
The DYNEV II simulation model is designed to accept varying rates of vehicle trip generation for each origin centroid, expressed in the form of histograms. These histograms, which represent Distributions A, C, D, E, and F, properly displaced with respect to one another, are tabulated in Table 59 (Distribution B, Arrive Home, omitted for clarity).
The final time period (15) is 600 minutes long. This time period is added to allow the analysis network to clear, in the event congestion persists beyond the trip generation period. Note that there are no trips generated during this final time period.

5.4.2 Staged Evacuation Trip Generation As defined in NUREG/CR7002, Rev. 1, staged evacuation consists of the following:
: 1. Zones comprising the 2Mile Radius are advised to evacuate immediately.
: 2. Zones comprising regions extending from 2 to 5 miles downwind are advised to shelter inplace while the 2Mile Radius is cleared.
: 3. As vehicles evacuate the 2Mile Radius, sheltered people from 2 to 5 miles downwind continue preparation for evacuation.
: 4. The population sheltering in the 2 to 5Mile Radius are advised to begin evacuating when approximately 90 percent of those originally within the 2Mile Radius evacuate across the 2Mile Radius boundary.
: 5. The population between the 5Mile Radius Boundary to EPZ boundary shelters in place.
: 6. Noncompliance with the shelter recommendation is the same as the shadow evacuation percentage of 20 percent.
Assumptions
: 1. The EPZ population in Zones beyond 5 miles will shelterinplace. A noncompliance voluntary evacuation percentage of 20 percent is assumed for this population.
: 2. The population in the Shadow Region beyond the EPZ boundary, extending to approximately 15 miles radially from the plant, will react as they do for all nonstaged evacuation scenarios. That is 20 percent of these households will elect to evacuate with no shelter delay.
: 3. The transient population will not be expected to stage their evacuation because of the limited sheltering options available to people who may be at parks, on a beach, or at other venues. Also, notifying the transient population of a staged evacuation would prove difficult.
: 4. Employees will also be assumed to evacuate without first sheltering.
Procedure
: 1. Trip generation for population groups in the 2Mile Radius will be as computed based upon the results of the demographic survey and analysis.
: 2. Trip generation for the population subject to staged evacuation will be formulated as follows:
: a. Identify the 90th percentile evacuation time for the Zones comprising the 2Mile Radius. This value, TScen*, is obtained from simulation results. It will become the time at which the region being sheltered will be told to evacuate for each scenario.
: b. The resultant trip generation curves for staging are then formed as follows:
: i. The nonshelter trip generation curve is followed until a maximum of 20 percent of the total trips are generated (to account for shelter non compliance).

Evacuation Time Estimate                                                                        Rev. 0
 
ii. No additional trips are generated until time TScen*
iii. Following time TScen*, the balance of trips are generated:
: 1. by stepping up and then following the nonshelter trip generation curve (if TScen* is < max trip generation time) or
: 2. by stepping up to 100 percent (if TScen* is > max trip generation time)
: c. Note: This procedure implies that there may be different staged trip generation distributions for different scenarios. NUREG/CR7002, Rev. 1, uses the statement approximately 90th percentile as the time to end staging and begin evacuating.
The value of TScen* is 2:50 for all scenarios (see Region R01 in Table 71).
: 3. Staged trip generation distributions are created for the following population groups:
: a. Residents with returning commuters
: b. Residents without returning commuters
: c. Residents with returning commuters while ice
: d. Residents without returning commuters while ice Figure 55 and Table 510 presents the staged trip generation distributions for both residents with and without returning commuters; on average, the 90th percentile 2Mile Radius evacuation time is 170 minutes for all scenarios. At TScen*, 20 percent of the permanent resident population (who normally would have completed their mobilization activities for an unstaged evacuation) advised to shelter has nevertheless departed the area. These people do not comply with the shelter advisory. Also included on the plot are the trip generation distributions for these groups as applied to the regions advised to evacuate immediately.
Since the 90th percentile evacuation time occurs before the end of the trip generation time, after the sheltered region is advised to evacuate, the shelter trip generation distribution rises to meet the balance of the nonstaged trip generation distribution. Following time TScen*, the balance of staged evacuation trips that are ready to depart are released. At 180 minutes, the remainder of evacuation trips are generated in accordance with the unstaged trip generation distribution.
Figure 55 and Table 510 provides the trip generation histograms for staged evacuation.
5.4.3 Trip Generation for Waterways and Recreational Areas The 2022 Emergency Preparedness Information for MNS indicates that boaters within a tenmile radius of MNS, will be notified by local fire, police and emergency officials using boats, loudspeakers and any means necessary to alert those on waterways and in recreational areas.
Boats/vessels will patrol assigned areas covering all navigable river, creek, lake and cove areas making contact with boaters and other individuals in the area. Boats will cover preassigned areas at an appropriate speed for current weather and safety conditions while displaying airborne red flares.
As discussed in Section 2.3, this study assumes a rapidly escalating accident. As indicated in Table 52, this study assumes 100 percent notification in 45 minutes which is consistent with the FEMA McGuire Nuclear Station                              59                          KLD Engineering, P.C.

REP Manual. Table 59 indicates that all transients will have mobilized within 2 hours. It is assumed that this timeframe is sufficient time for boaters, campers and other transients to return to their vehicles or lodging facilities and begin their evacuation trip.

6    EVACUATION CASES An evacuation case defines a combination of Evacuation Region and Evacuation Scenario.
The definitions of Region and Scenario are as follows:
Region            A grouping of contiguous evacuating Zones that forms either a keyhole sectorbased area, or a circular area within the EPZ, that must be evacuated in response to a radiological emergency.
Scenario          A combination of circumstances, including time of day, day of week, season, and weather conditions. Scenarios define the number of people in each of the affected population groups and their respective mobilization time distributions.
A total of 35 Regions were defined which encompass all the groupings of Zones considered.
These Regions are defined in Table 61. The Zone configurations are identified in Figure 61.
Each keyhole sectorbased area consists of a central circle centered at the power plant, and three adjoining sectors, each with a central angle of 22.5 degrees, as per NUREG/CR7002, Rev.1 guidance. The central sector coincides with the wind direction. These sectors extend to 5 miles from the plant (Regions R04 through R10) or to the EPZ boundary (Regions R11 through R25).
Regions R01, R02 and R03 represent evacuations of circular areas with radii of 2, 5 and 10 miles, respectively. Regions R28 through R35 are identical to Regions R04 through R10 and R02, respectively; however, those Zones between 2 miles and 5 miles are staged until 90% of the 2 mile region (Region R01) has evacuated.
A total of 14 scenarios were evaluated for all Regions. Thus, there are a total of 490 (35x14=490) evacuation cases. Table 62 is a description of all Scenarios.
Each combination of Region and Scenario implies a specific population to be evacuated. The population group and the vehicle estimates presented in Section 3 and Appendix E are peak values. These peak values are adjusted depending on the scenario and region being considered, using scenario and regionspecific percentages; such that the average population is considered for each evacuation case. The scenario percentages are presented in Table 63, while the regional percentages are provided in Table H1.
Table 64 presents the vehicle counts for each scenario for an evacuation of Region R03 - the entire EPZ, based on the scenario percentages in Table 63. The percentages presented in Table 63 were determined as follows:
The number of residents with commuters during the week (when workforce is at its peak) is equal to 22%, which is the product of 43% (the number of households with at least one commuter see Figure F6) and 51% (the number of households with a commuter that would await the return of the commuter prior to evacuatingsee Figure F11). See assumption 3 in Section 2.3. It is estimated for weekend and evening scenarios that 10% of those households with commuters will have a commuter at work during those times.

Evacuation Time Estimate                                                                      Rev. 0
 
It can be argued that the estimate of permanent residents overstates, somewhat, the number of evacuating vehicles, especially during the summer. It is certainly reasonable to assert that some portion of the population would be on vacation during the summer and would travel elsewhere. A rough estimate of this reduction can be obtained as follows:
Assume 50 percent of all households vacation for a period over the summer.
Assume these vacations, in aggregate, are uniformly dispersed over 10 weeks, i.e. 10 percent of the population is on vacation during each twoweek interval.
Assume half of these vacationers leave the area.
On this basis, the permanent resident population would be reduced by 5 percent in the summer and by a lesser amount in the offseason. Given the uncertainty in this estimate, we elected to apply no reductions in permanent resident population for the summer scenarios to account for residents who may be out of the area.
Employment is estimated to be at its peak (100%) during the winter, midweek, midday scenarios. Employment is reduced slightly (96%) for summer, midweek, midday scenarios. This is based on the estimation that 50% of the employees commuting into the EPZ will be on vacation for a week during the approximate 12 weeks of summer. It is further estimated that those taking vacation will be uniformly dispersed throughout the summer with approximately 4% of employees vacationing each week. Finally, it is estimated that only 10% of the employees are working in the evenings and during the weekends.
As shown in Appendix E, there is a significant amount of lodging facilities (see Table E8) and campgrounds offering overnight accommodations in the EPZ; thus, transient activity is estimated to be peak (60%) during the evening for summer and slightly less (55%) for winter.
Transient activity is estimated to be high (50%) during summer weekends and less (30%) during the week. The recreational areas in the EPZ (shown in Table E5 through E8) are predominantly outdoors and will be frequented more often during the summer than the winter. As a result, transient activity during winter weekends is estimated to be 25%. It is assumed that weekend activity at transient attractions is higher than weekday activity during the winter. As such, during winter weekdays, transient activity is assumed to be 15%.
As noted in the shadow footnote to Table 63, the shadow percentages are computed using a base of 20% (see assumption 7 in Section 2.2); to include the employees within the shadow region who may choose to evacuate, the voluntary evacuation is multiplied by a scenario specific proportion of employees to permanent residents in the shadow region. For example, using the values provided in Table 64 for Scenario 1, the shadow percentage is computed as follows:
31,493 20%  1                        25%
28,577  101,598 One special event - Carolina Renaissance Festival - was considered as Scenario 13. Thus, the special event traffic is 100% evacuated for Scenario 13, and 0% for all other scenarios.

As discussed in Section 7, schools, preschools, and childcare centers are in session during the winter season, midweek, midday and 100% of buses will be needed under those circumstances.
It is estimated that summer school enrollment is approximately 10% of enrollment during the regular school year for summer, midweek, midday scenarios. School is not in session during weekends and evenings, thus no buses for school children are needed under those circumstances. The commuting college students at Central Piedmont Community College Merancas Campus and Davidson College, who live outside of the EPZ, are assumed to have the same scenario percentages as the schools within the EPZ.
Transit buses for the transitdependent population and vehicles for medical and correctional facilities are set to 100% for all scenarios as it is assumed that the transitdependent, medical facility, and correctional facility population are present in the EPZ for all scenarios.
External traffic is estimated to be reduced by 60% during evening scenarios (Scenario 5 and 12) and is 100% for all other scenarios.

This section presents the ETE results of the computer analyses using the DYNEV II model described in Appendices B, C and D. These results cover 35 regions within the McGuire Nuclear Station (MNS) Emergency Planning Zone (EPZ) and the 14 Evacuation Scenarios discussed in Section 6.
The ETE for all Evacuation Cases are presented in Table 71 and Table 72. These tables present the estimated times to clear the indicated population percentages from the Evacuation Regions for all Evacuation Scenarios. The ETE of the 2Mile Radius in both staged and unstaged regions are presented in Table 73 and Table 74. Table 75 defines the Evacuation Regions considered.
The tabulated values of ETE are obtained from the DYNEV II model outputs which are generated at 5minute intervals.
7.1    Voluntary Evacuation and Shadow Evacuation Voluntary evacuees are permanent residents within the EPZ in Zones for which an Advisory to Evacuate (ATE) has not been issued, yet who elect to evacuate. Shadow evacuation is the voluntary outward movement of some permanent residents from the Shadow Region (outside the EPZ) for whom no protective action recommendation (PAR) has been issued. Both voluntary and shadow evacuations are assumed to take place over the same time frame as the evacuation from within the impacted Evacuation Region.
The ETE for the MNS EPZ addresses the issue of voluntary evacuees in the manner shown in Figure 71. Within the EPZ, 20 percent of permanent residents located in zones outside of the evacuation region who are not advised to evacuate, are assumed to elect to evacuate. Similarly, it is assumed that 20 percent of those people in the Shadow Region will choose to leave the area.
Figure 72 presents the area identified as the Shadow Region. This region extends radially from the plant to cover a region between the EPZ boundary and approximately 15 miles. The population and number of evacuating vehicles in the Shadow Region were estimated using the same methodology that was used for permanent residents within the EPZ (see Section 3.1). As discussed in Section 3.2, it is estimated that a total of 379,976 people reside in the Shadow Region; 20 percent of them would evacuate. See Table 64 for the number of evacuating vehicles from the Shadow Region.
Traffic generated within this Shadow Region (including externalexternal traffic), traveling away from the MNS location, has the potential for impeding evacuating vehicles from within the Evacuation Region. All ETE calculations include this shadow traffic movement.

7.2    Staged Evacuation As defined in NUREG/CR7002, Rev. 1, staged evacuation consists of the following:
: 1. Zones comprising the 2Mile Radius are advised to evacuate immediately.
: 2. Zones comprising regions extending from 2 to 5 miles downwind are advised to shelter inplace while the 2Mile Radius is cleared.
: 3. As vehicles evacuate the 2Mile Radius, people from 2 to 5 miles downwind continue preparation for evacuation while they shelter.
: 4. The population sheltering in the 2 to 5mile region is advised to evacuate when approximately 90% of the 2Mile Radius evacuating traffic crosses the 2Mile Radius boundary.
: 5. Noncompliance with the shelter recommendation is the same as the shadow evacuation percentage of 20%.
See Section 5.4.2 for additional information on staged evacuation.
7.3    Patterns of Traffic Congestion during Evacuation Figure 73 through Figure 710 illustrate the patterns of traffic congestion that arise for the case when the entire EPZ (Region R03) is advised to evacuate during the summer, midweek, midday period under good weather conditions (Scenario 1).
Traffic congestion, as the term is used here, is defined as Level of Service (LOS) F. LOS F is defined as follows (HCM 2016, page 55):
The HCM uses LOS F to define operations that have either broken down (i.e., demand exceeds capacity) or have reached a point that most users would consider unsatisfactory, as described by a specified service measure value (or combination of service measure values). However, analysts may be interested in knowing just how bad the LOS F condition is, particularly for planning applications where different alternatives may be compared. Several measures are available to describe individually, or in combination, the severity of a LOS F condition:
* Demandtocapacity ratios describe the extent to which demand exceeds capacity during the analysis period (e.g., by 1%, 15%).
* Duration of LOS F describes how long the condition persists (e.g., 15 min, 1 h, 3 h).
* Spatial extent measures describe the areas affected by LOS F conditions. These include measures such as the back of queue and the identification of the specific intersection approaches or system elements experiencing LOS F conditions.
All highway "links" which experience LOS F are delineated in these figures by a thick red line; all others are lightly indicated. Congestion develops rapidly around concentrations of population and traffic bottlenecks.

Figure 73 displays the developing congestion along interstate 77 (I77), I85 and I485 which service the externalexternal trips through the EPZ just 30 minutes after the Advisory to Evacuate (ATE). North Carolina Highway73 (NC73) also experiences LOS F conditions eastbound east of the plant, as it is one of the major evacuation routes that gives direct access to I85. Congestion is also developing to the east in Mt. Mourne, Davidson, Cornelius, Huntersville and to the southeast in the suburbs of Charlotte as these are the most populated areas in the EPZ.
At one hour after the ATE, Figure 74 displays congestion continuing to worsen within Cornelius, Davidson and Huntersville along I77 and roads accessing the ramps to the interstate, as well as the portion of Charlotte within the EPZ and Shadow Region. Many of the major roads servicing the eastern half of the EPZ have sections that are operating at LOS F. I77 is also operating at LOS F throughout the entire EPZ and most of the Shadow Region. There is also pronounced congestion in Zone P. Most of this congestion is the result of a significant bottleneck caused by the merging of NC16 and the NC16 Bypass north of the EPZ, as well as the densely populated communities of Denver and Westport that utilize NC16. At this time, approximately 28% of vehicles have begun their evacuation trip and 20% of evacuating vehicles have successfully evacuated the EPZ.
As shown in Figure 75, at two hours after the ATE, displays fully developed congestion within the EPZ. Congestion east of the plant has worsened, with nearly all northsouth and eastbound roadways are experiencing LOS F conditions. On the west side of the EPZ, NC16 and NC16 Business are severely congested and display LOS F conditions. At this time, access control has been established and external traffic has been diverted. Approximately 67% of vehicles have begun their evacuation trip, and 49% of evacuating vehicles have successfully evacuated the EPZ.
At 3 hours after the ATE, as shown in Figure 76, congestion begins to lessen throughout the EPZ. Most noticeably, Zones E, S, and Q. The merge of NC16 and NC16 Business creates a bottleneck causing congestion along these roadways in Zones P and N. The intersection of NC 150 and NC27 in Lincolnton is also a significant bottleneck which causes traffic to spillback into the EPZ. Significant congestion persists in the eastern portion of the EPZ - specifically in Zones A, B, H and G. I77 remains at LOS F throughout the majority of the study area. At this time, approximately 90% of vehicles have begun their evacuation trip and 73% of evacuating vehicles have successfully evacuated the EPZ.
At 4 hours after the ATE, as shown in Figure 77, congestion continues to dissipate. At this time, the 2Mile Radius is clear of congestion. The southwestern portion of the EPZ is clear of congestion. The outskirts of Charlotte have shown improvement, specifically in Zones E and F with congestion along I485 clearing completely. Congestion in Zone P had dissipated with only a small section of NC16 Business and St. James Church Rd between NC16 and NC16 Business exhibiting LOS F conditions. I77 is still operating at LOSF throughout the EPZ and parts of the Shadow Region. Many vehicles are bypassing I77 and traveling east along NC73 and HuntersvilleConcord Road to exit the EPZ and avoid the delays along I77. These roads lead evacuees towards Kannapolis and Northwest Cabarrus Middle School, a reception center for McGuire Nuclear Station                          73                            KLD Engineering, P.C.

the general public, as well as to I85. At this time, about 96% of vehicles have begun their evacuation trip and 88% of evacuating vehicles have successfully evacuated the EPZ.
Over the next hour, at 5 hours after the ATE (Figure 78), congestion continues to dissipate with the entire western portion of the EPZ is now clear of congestion, as well as Zones E and F. The 5mile region is nearly clear of congestion (clears 5 minutes later at 5:05 after the ATE).
Congestion remains within the EPZ along I77 northbound, NC73, E Rocky River Rd, Catawba Ave, NC115, Poplar Tent Church Rd, and HuntersvilleConcord Rd. At this time, 99% vehicles have begun their evacuation trip and 97% of evacuating vehicles have successfully evacuated the EPZ.
At 5 hours and 30 minutes after the ATE, as shown in Figure 79, the last remnants of congestion within the EPZ can be seen along I77 northbound. At this time, all vehicles have fully mobilized and 99% of vehicles have evacuated the EPZ. The EPZ is completely clear of all congestion ten minutes later at 5 hours and 40 minutes after the ATE.
Finally, Figure 710 displays the time at which the study area completely clear of congestion and at the completion of trip generation at 6 hours after the ATE. All vehicles successfully clear the EPZ ten minutes later at 6 hour and 10 minutes after the ATE. The last roadway to clear of congestion within the Shadow Region was I77 northbound and it cleared 5 minutes earlier.
Congestion remains, however, outside of the study area along I77, US Highway21 (US21) and NC27.
7.4    Evacuation Rates Evacuation is a continuous process, as implied by Figure 711 through Figure 724. These Figures indicate the rate at which traffic flows out of the indicated areas for the case of an evacuation of the full EPZ (Region R03) under the indicated conditions. One figure is presented for each scenario considered.
As indicated in Figure 711 through Figure 724, there is typically a long "tail" to these distributions. Vehicles begin to evacuate an area slowly at first, as people respond to the ATE at different rates. Then traffic demand builds rapidly (slopes of curves increase). When the system becomes congested, traffic exits the EPZ at rates somewhat below capacity until some evacuation routes have cleared. As more routes clear, the aggregate rate of egress slows since many vehicles have already left the EPZ. Towards the end of the process, relatively few evacuation routes service the remaining demand.
This decline in aggregate flow rate, towards the end of the process, is characterized by these curves flattening and gradually becoming horizontal. Ideally, it would be desirable to fully saturate all evacuation routes equally so that all will service traffic near capacity levels and all will clear at the same time. For this ideal situation, all curves would retain the same slope until the end - thus minimizing evacuation time. In reality, this ideal is generally unattainable reflecting the spatial variation in population density, mobilization rates and in highway capacity over the EPZ.

7.5    Evacuation Time Estimate (ETE) Results Table 71 through Table 72 present the ETE values for all 30 Evacuation Regions and all 14 Evacuation Scenarios. Table 73 through Table 74 present the ETE values for the 2Mile Radius for both staged and unstaged keyhole regions downwind to 5 miles. The tables are organized as follows:
Table                                            Contents The ETE represents the elapsed time required for 90% of the population within a 71        Region, to evacuate from that Region. All Scenarios are considered, as well as Staged Evacuation scenarios.
The ETE represents the elapsed time required for 100% of the population within a 72        Region, to evacuate from that Region. All Scenarios are considered, as well as Staged Evacuation scenarios.
The ETE represents the elapsed time required for 90% of the population within the 2 73        Mile Radius, to evacuate from that Region with both Concurrent and Staged Evacuations of additional Zones downwind in the keyhole Region.
The ETE represents the elapsed time required for 100% of the population within the 74        2Mile Radius, to evacuate from that Region with both Concurrent and Staged Evacuations of additional Zones downwind in the keyhole Region.
The animation snapshots described in Section 7.3 reflect the ETE statistics for the concurrent (unstaged) evacuation scenarios and regions, which are displayed in Figure 73 through Figure 710. Most of the congestion is located in the eastern portion of the EPZ in Zones A, D, F, G, H I, and J which are beyond the 2mile region; this is reflected in the ETE statistics:
The 90th percentile ETE for Region R01 (2Mile Radius) is 2:50 (hr:min) for all scenarios.
The 90th percentile ETE for Regions R02 (5Mile Radius) and R04 through R10 (which extend to 5 miles from MNS) generally range between 2:50 and 3:40.
The 90th percentile ETE for Region R03 (full EPZ) and Regions R11 through R25 (which extend to the EPZ boundary) range between 2:50 and 5:30.
The 100th percentile ETE for all 2 and 5Mile Regions for most of the nonice Scenarios generally parallel the mobilization times (6:00 for residents with returning commuters plus 5 to 10 minutes travel time to exit the EPZ). This implies that the congestion within these portions of the EPZ dissipates prior to the end of mobilization for nonice cases -
as shown in Figure 73 through Figure 710 and discussed in Section 7.3. The 100th percentile ETE ranges from 6:00 to 6:30 for good weather and rain cases, and from 6:30 to 7:30 for ice cases.
Comparison of Scenarios 9 and 13 in Table 71 indicates that the Special Event - Carolina Renaissance Festival - has minimal to no impact on the 90th percentile ETE (up to 15minute increases in ETE for some cases), as shown in Table 71. The additional 2,857 vehicles present for the special event do not significantly increase congestion on the local roads (in Zone G) such McGuire Nuclear Station                            75                              KLD Engineering, P.C.

that ETE is impacted. As previously discussed, the 100th percentile ETE are dictated by trip generation and, as a result, are not impacted by the special event.
Comparison of Scenarios 1 and 14 in Table 71 indicates that the roadway closure - a single lane southbound on Interstate77 (I77) from the interchange with NC73/Sam Furr Rd (Exit 25) to the interchange with County Route115/ Sunset Rd (Exit 16A) - does not have a material impact on 90th percentile ETE - 15 minute increase at most. Despite I77 being a primary evacuation route for the eastern portion of the EPZ, there are plenty of other alternatives to this road including I77 northbound, I485, US 21, NC 115, NC 73, and NC 24. In addition, I77 is already operating well below capacity and many vehicles are already choosing alternate paths to evacuate the area. As a result, the loss of a lane on I77 simply encourages more vehicles to utilize these other paths. While congested does increase, it does not cause a significant change in ETE. The single lane closure has no impact on the 100th percentile ETE, as the trip generation (plus the travel time to the EPZ boundary) dictates the ETE for all cases for Scenario 1 and 14.
The results of the roadway impact scenario indicate that events such as adverse weather or traffic accidents which close a lane on I77, could impact ETE. State and local police could consider traffic management tactics such as using the shoulder of the roadway as a travel lane or rerouting of traffic along other evacuation routes to avoid overwhelming I77.
7.6    Staged Evacuation Results Table 73 and Table 74 present a comparison of the ETE compiled for the concurrent (un staged) and staged evacuation studies. Note that Regions R28 through R35 are the same geographic areas as Regions R04 through R10 and R02, respectively. The times shown in Table 73 and Table 74 are when the 2Mile Radius is 90% clear and 100% clear, respectively.
The objective of a staged evacuation strategy is to show that the ETE for the 2Mile Radius can be significantly reduced (30 minutes or 25%, whichever is less) without significantly impacting the region between 2 miles and 5 miles. In all cases, as shown in Table 73 and Table 74, the 90th and 100th percentile ETE for the 2Mile Radius remains the same when a staged evacuation is implemented for all scenarios. These results indicate that there is minimal congestion within the 2Mile Radius and when an evacuation out to 5 miles occurs, the congestion beyond 2 miles does not extend upstream to the extent that it penetrates to within 2 miles of the plant.
Evacuees from within the 2Mile Radius are not impacted by those evacuating beyond 2 miles out to 5 miles. Therefore, staging the evacuation provides no benefits to evacuees from within the 2Mile Radius.
To determine the effect of staged evacuation on residents beyond the 2Mile Radius, the ETE for Regions R04 through R10 and R02 are compared to Regions R28 through R34 and Region R35, respectively, in Table 71 and Table 72. A comparison of ETE between these similar regions reveals that staging increases the ETE for those in the 2 to 5mile area by at most 1 hour and 40 minutes (see Table 71) for the 90th percentile. The increase in the 90th percentile ETE is due to the large number of evacuating vehicles, beyond the 2Mile Region, sheltering and delaying the start of their evacuation. As shown in Figure 55, staging the evacuation causes a significant spike (sharp increase) in mobilization (tripgeneration rate) of evacuating vehicles.

Evacuation Time Estimate                                                                      Rev. 0
 
This spike oversaturates evacuation routes, which increases traffic congestion and prolongs ETE.
Therefore, staging evacuation provides no benefit to evacuees within the 2Mile Radius of MNS and adversely impacts many evacuees located beyond the 2Mile Radius. As such, a staged evacuation is not recommended for this site.
7.7  Guidance on Using ETE Tables The user first determines the percentile of population for which the ETE is sought (The NRC guidance calls for the 90th percentile). The applicable value of ETE within the chosen table may then be identified using the following procedure:
: 1. Identify the applicable Scenario:
* Season Summer Winter (also Autumn and Spring)
* Day of Week Midweek Weekend
* Time of Day Midday Evening
* Weather Condition Good Weather Rain Ice
* Special Event
* Carolina Renaissance Festival Road Closure (A single lane on I77 SB is closed)
* Evacuation Staging No, Staged Evacuation is not considered Yes, Staged Evacuation is considered While these Scenarios are designed, in aggregate, to represent conditions throughout the year, some further clarification is warranted:
* The conditions of a summer evening (either midweek or weekend) and rain are not explicitly identified in the Tables. For these conditions, Scenarios (2) and (4) apply.
* The conditions of a winter evening (either midweek or weekend) and rain are not explicitly identified in the Tables. For these conditions, Scenarios (7) and (10) for rain apply.
* The conditions of a winter evening (either midweek or weekend) and ice are not explicitly identified in the Tables. For these conditions, Scenarios (8) and (11) for ice apply.
* The seasons are defined as follows:

Evacuation Time Estimate                                                                          Rev. 0
 
Summer assumes that public schools are not in session.
Winter (includes Spring and Autumn) considers that public schools are in session.
* Time of Day: Midday implies the time over which most commuters are at work or are travelling to/from work.
: 2. With the desired percentile ETE and Scenario identified, now identify the Evacuation Region:
* Determine the projected azimuth direction of the plume (coincident with the wind direction). This direction is expressed in terms of compass orientation: from N, NNE, NE,
* Determine the distance that the Evacuation Region will extend from the nuclear power plant. The applicable distances and their associated candidate Regions are given below:
2 Miles (Region R01)
To 5 Miles (Region R02 and R04 through R10)
To EPZ Boundary (Regions R03 and R11 through R25)
* Enter Table 75 and identify the applicable group of candidate Regions based on the distance that the selected Region extends from the plant. Select the Evacuation Region identifier in that row, based on the azimuth direction of the plume, from the first column of the Table.
: 3. Determine the ETE Table based on the percentile selected. Then, for the Scenario identified in Step 1 and the Region identified in Step 2, proceed as follows:
* The columns of Table 71 through Table 74 are labeled with the Scenario numbers.
Identify the proper column in the selected Table using the Scenario number defined in Step 1.
* Identify the row in this table that provides ETE values for the Region identified in Step 2.
* The unique data cell defined by the column and row so determined contains the desired value of ETE expressed in Hours: Minutes.
Example It is desired to identify the ETE for the following conditions:
* Sunday, August 10th at 10:00 PM (Summer, weekend, evening)
* It is raining.
* Wind direction is from the north (N).
* Wind speed is such that the distance to be evacuated is judged to be a 5Mile Radius and downwind to 10 miles (to EPZ boundary).
* The desired ETE is that value needed to evacuate 90 percent of the population from within the impacted Region.
* A staged evacuation is not desired.

Table 71 is applicable because the 90th percentile ETE is desired. Proceed as follows:
: 1. Identify the Scenario as summer, weekend, evening and raining. Entering Table 71, it is seen that there is no match for these descriptors. However, the clarification given above assigns this combination of circumstances to Scenario 4.
: 2. Enter Table 75 and locate the Region described as Evacuate 5Mile Radius and Downwind to EPZ Boundary for wind direction from the N and read Region R11 in the first column of that row.
: 3. Enter Table 71 to locate the data cell containing the value of ETE for Scenario 4 and Region R11. This data cell is in column (4) and in the row for Region R11; it contains the ETE value of 3:20.

8    TRANSITDEPENDENT AND SPECIAL FACILITY EVACUATION TIME ESTIMATES This section details the analyses applied and the results obtained in the form of evacuation time estimates (ETE) for transit vehicles, buses, vans, ambulances, and wheelchair transport vehicles.
The demand for transit service reflects the needs of three population groups:
residents with no vehicles available; residents of special facilities such as schools, preschools and childcare centers, medical facilities, and correctional facilities; and access and/or functional needs population.
These transit vehicles mix with the general evacuation traffic that is comprised mostly of passenger cars (pcs). The presence of each transit vehicle in the evacuating traffic stream is represented within the modeling paradigm described in Appendix D as equivalent to two pcs.
This equivalence factor represents the longer size and more sluggish operating characteristics of a transit vehicle, relative to those of a pc. Ambulances and vans are considered one pc.
Transit vehicles must be mobilized in preparation for their respective evacuation missions.
Specifically:
* Bus drivers must be alerted
* They must travel to the bus depot
* They must be briefed there and assigned to a route or facility These activities consume time. The location of bus depots impacts the time to travel from the bus depots to the facilities being evacuated. Locations of bus depots were not identified in this study. Rather, the offsite agencies were asked to factor the location of the depots and the distance to the EPZ into the estimate of mobilization time.
During this mobilization period, other mobilization activities are taking place. One of these is the action taken by parents, neighbors, relatives and friends to pick up children from school prior to the arrival of buses, so that they may join their families. Virtually all studies of evacuations have concluded that this bonding process of uniting families is universally prevalent during emergencies and should be anticipated in the planning process. The current public information disseminated to residents of the MNS EPZ indicates that schoolchildren will be evacuated to relocation schools/reception centers (pickup facilities) if an evacuation were ordered, and that parents should pick schoolchildren up at the pickup facilities. As discussed in Section 2, this study assumes a rapidly escalating event. Therefore, children are evacuated to pickup facilities. Picking up children at school could add to traffic congestion at the schools, delaying the departure of the buses evacuating schoolchildren, which may have to return in a subsequent wave to the EPZ to evacuate the transitdependent population. This report provides estimates of buses under the assumption that no children will be picked up by their parents (in accordance with NUREG/CR 7002, Rev. 1), to present an upper bound estimate of buses required. As stated in the public information brochure, for Lincoln County, all childcare facilities will be moved to S. Ray Lowder Elementary school and all private schools not specifically listed will be moved to Lincolnton McGuire Nuclear Station                            81                            KLD Engineering, P.C.

Middle School. All other childcare facilities in the EPZ will be moved to the reception center for the Zone in which that facility is located.
The procedure for computing transitdependent ETE is to:
* Estimate demand for transit service (discussed in Section 3)
* Estimate time to perform all transit functions
* Estimate route travel times to the EPZ boundary and to the relocation school/reception centers Evacuation Time Estimates for transit trips were developed using both good weather and adverse weather conditions. Figure 81 presents the chronology of events relevant to transit operations.
The elapsed time for each activity will now be discussed with reference to Figure 81.
8.1    ETEs for Schools, Preschool and Childcare Centers, Transit Dependent People, and Medical and Correctional Facilities The EPZ bus resources are assigned to evacuating schoolchildren (if school is in session at the time of the Advisory to Evacuate [ATE]) as the first priority in the event of an emergency. In the event that the allocation of buses dispatched from the depots to the various facilities and to the bus routes is somewhat inefficient, or if there is a shortfall of available drivers, then there may be a need for some buses to return to the EPZ from the relocation school/ reception center after completing their first evacuation trip, to complete a second wave of providing transport service to evacuees. For this reason, the ETE for the transitdependent population are calculated for both a one wave transit evacuation and for two waves. Of course, if the impacted Evacuation Region is other than R03 (the entire EPZ), then there will likely be ample transit resources relative to demand in the impacted Region and this discussion of a second wave would likely not apply.
A list of available transportation resources was provided by counties within the EPZ and is shown in Table 81. It is assumed that there are enough drivers available to man all resources listed in Table 81.
When school evacuation needs are satisfied, subsequent assignments of buses to service the transitdependent should be sensitive to their mobilization time. Clearly, the buses should be dispatched after people have completed their mobilization activities and are in a position to board the buses when they arrive along the bus transit route.
Evacuation of Schools, Preschools and Childcare Centers Activity: Mobilize Drivers (ABC)
Mobilization is the elapsed time from the ATE until the time the buses arrive at the school or preschool and childcare center to be evacuated. As discussed in item 4 of Section 2.4, it is estimated that for a rapidly escalating radiological emergency with no observable indication before the fact, drivers would likely require 120 minutes to be contacted, to travel to the depot, be briefed, and to travel to the schools, preschools and childcare centers that will be evacuated.
Mobilization time is slightly longer in adverse weather - 130 minutes in rain and 140 minutes in icy conditions.

Activity: Board Passengers (CD)
Based on discussions with offsite agencies, a loading time of 15 minutes for good weather (20 minutes for rain and 25 minutes for ice) for school buses is used.
Activity: Travel to EPZ Boundary (DE)
The buses servicing the schools, preschools and childcare centers are ready to begin their evacuation trips at 135 minutes after the ATE - 120 minutes mobilization time plus 15 minutes loading time - in good weather. The UNITES software discussed in Section 1.3 was used to define bus routes along the most likely path from a school or preschool and childcare center being evacuated to the EPZ boundary, traveling toward the appropriate relocation school/reception center. This is done in UNITES by interactively selecting the series of nodes from the school/preschool/childcare center to the EPZ boundary. Each bus route is given an identification number and is written to the DYNEV II input stream. DYNEV computes the route length and outputs the average speed for each 5minute interval, for each bus route. The specified bus routes are documented in Table 102 (refer to the maps of the linknode analysis network in Appendix K for node locations). Data provided by DYNEV during the appropriate timeframe depending on the mobilization and loading times (i.e., 130 to 135 minutes after the ATE for good weather) were used to compute the average speed for each route, as follows:
60 .
1 .
                                              .          60 .
              .                                  .      1 .
The average speed computed (using this methodology) for the buses servicing each of the schools, preschools and childcare centers in the EPZ is shown in Table 82 through Table 84 for school/preschool/childcare center evacuation. The travel time to the EPZ boundary was computed for each bus using the computed average speed and the distance to the EPZ boundary along the most likely route out of the EPZ. The travel time from the EPZ boundary to the relocation school/reception center was computed assuming an average speed of 45 mph, 40 mph, and 35 mph for good weather, rain and ice, respectively. Speeds were reduced in Table 82 through Table 84 to 45 mph (40 mph for rain - 10% decrease, rounded to the nearest 5 mph -
and 35 mph for ice - 20% decrease, rounded to the nearest 5 mph) for those calculated bus speeds which exceed 45 mph, as the school bus speed limit for state routes within the EPZ is 45 mph.
Table 82 (good weather), Table 83 (rain) and Table 84 (ice) present the following evacuation time estimates (rounded up to the nearest 5 minutes) for schools, preschools and childcare centers in the EPZ:

: 1. The elapsed time from the ATE until the bus exits the EPZ; and
: 2. The elapsed time until the bus reaches the relocation school/reception center.
The evacuation time out of the EPZ can be computed as the sum of times associated with Activities ABC, CD, and DE (For example: 120 min. + 15 + 16 = 2:35, rounded up to the nearest 5 minutes, for Mountain Island Charter School, in good weather).
The average singlewave ETE, for schools, preschools and childcare centers is 1 hour and 5 minutes (4:15  3:10 = 1:05) less than the 90th percentile ETE for evacuation of the general population in the entire EPZ (Region R03) under winter, midweek, midday, good weather (Scenario 6) conditions and will not impact protective action decision making.
The evacuation time to the relocation school /reception center is determined by adding the time associated with Activity EF (discussed below), to this EPZ evacua on me.
Activity: Travel to Relocation Schools/Reception Centers (EF)
The distances from the EPZ boundary to the relocation schools/reception centers are measured using geographic information system (GIS) software along the most likely route from the EPZ exit point to the relocation school/reception center. The relocation schools/reception centers are mapped in Figure 104. For a singlewave evacuation, this travel time outside the EPZ does not contribute to the ETE. Assumed bus speeds of 45 mph, 40 mph, and 35 mph for good weather, rain, and ice, respectively, will be applied for this activity for buses servicing the school, preschool and childcare center population.
Activity: Passengers Leave Bus (FG)
A bus can empty within 5 minutes. The driver takes a 10minute break.
Activity: Bus Returns to Route for Second Wave Evacuation (GCDE)
As shown in Table 81, there is a shortfall of buses for evacuation of children in a single wave, if the entire EPZ is evacuated at once (a highly unlikely event). As such, a twowave evacuation may be needed for some schools, preschools and childcare centers. Due to the large number of schools, preschools and childcare centers in the EPZ, second wave ETE were not computed for each school/preschool/childcare center. Rather, the following representative ETE is provided to estimate the additional time needed for a second wave evacuation of schools, preschools and childcare centers. The travel time from the relocation school/reception center back to the EPZ boundary and then back to the school/ preschool/childcare center was computed assuming an average speed of 45 mph (good weather), 40 mph (rain) and 35 mph (ice) as buses will be traveling counter to evacuating traffic. Times and distances are based on averages for all schools, preschools and childcare centers in the EPZ for good weather:
* Buses arrive at the relocation school/reception center at 3:20 (see average value in Table 82)
* Bus discharges passengers (5 minutes) and driver takes a 10minute rest: 15 minutes
* Bus returns to facility: 20 minutes (average distance to relocation school/reception center (9.4 miles) + average distance to EPZ boundary (5.6 miles) at 45 mph)
* Loading Time: 15 minutes McGuire Nuclear Station                            84                                KLD Engineering, P.C.
Evacuation Time Estimate                                                                            Rev. 0
* Bus travels back to the EPZ boundary: 27 minutes [average distance to EPZ boundary (5.7 miles) at network wide average speed at 4:10 (12.98 mph)]
* Bus exits EPZ at time 3:20 + 0:15 + 0:20 + 0:15 + 0:27 = 4:40 (rounded up to nearest 5 minutes) after the ATE.
Given the average singlewave ETE for schools, preschools and childcare centers is 3:10 (see Table 82); a secondwave evacuation would require an additional 1 hour and 30 minutes on average.
The average twowave ETE of schools and childcare centers is 25 minutes (4:404:15=0:25) higher than the 90th percentile ETE of the full EPZ during a winter, midweek, midday scenario (Scenario 6), which could potentially impact protective action decision making.
Evacuation of Transit Dependent People (Residents without access to a vehicle)
A detailed computation of transit dependent population was done and is discussed in Section 3.6. The total number of transit dependent people per Zone was determined using a weighted distribution based on population. See Table 311 for the distribution used. The number of buses required to evacuate this population was determined by the capacity of 30 people per bus. KLD designed 19 bus routes to service the major evacuation routes in each Zone, for the purposes of this study. The predefined bus routes (as discussed in Section 10) are shown graphically in Figure 102 and Figure 103 and described in Table 101. Those buses servicing the transitdependent evacuees will first travel along these routes, then proceed out of the EPZ.
Activity: Mobilize Drivers (ABC)
Mobilization time is the elapsed time from the ATE until the time the buses arrive at their designated route. The buses dispatched from the depots to service the transitdependent evacuees will be scheduled so that they arrive at their respective routes after majority of their passengers have completed their mobilization. As shown in Figure 54 (Residents with no Commuters), approximately 90% of the evacuees will have completed their mobilization when the buses will begin their routes, approximately 160 minutes after the ATE for good weather.
Those routes with multiple buses have been designed such that buses are dispatched using 10 minute headways. The use of bus headways ensures that those people who take longer to mobilize will be picked up.
Activity: Board Passengers (CD)
For multiple stops along a route, estimation of travel time must allow for the delay associated with stopping and starting at each pickup point. The time, t, required for a bus to decelerate at a rate, a, expressed in ft/sec/sec, from a speed, v, expressed in ft/sec, to a stop, is t = v/a.
Assuming the same acceleration rate and final speed following the stop yields a total time, T, to service boarding passengers:
2          ,
Where B = Dwell time to service passengers. The total distance, s in feet, travelled during the deceleration and acceleration activities is: s = v2/a. If the bus had not stopped to service passengers, but had continued to travel at speed, v, then its travel time over the distance, s, would be: s/v = v/a. Then the total delay (i.e. pickup time, P) to service passengers is:

Evacuation Time Estimate                                                                      Rev. 0
 
Assigning reasonable estimates:
* B = 50 seconds: a generous value for a single passenger, carrying personal items, to board per stop
* v = 25 mph = 37 ft/sec
* a = 4 ft/sec/sec, a moderate average rate Then, P  1 minute per stop. Allowing 30 minutes pickup time per bus run implies 30 stops per run, for good weather. It is assumed that bus acceleration and speed will be less in rain and ice; total loading time is 40 minutes per bus for rain and 50 minutes for ice.
Activity: Travel to EPZ Boundary (DE)
The travel distance along the respective pickup routes within the EPZ is estimated using the UNITES software. Bus travel times within the EPZ are computed using average speeds computed by DYNEV, using the aforementioned methodology that was used for school, preschool and childcare center evacuation.
Table 85 through Table 87 present the transitdependent population ETEs for each bus route calculated using the above procedures (as discussed under Evacuation of Schools, Preschools and Childcare Centers) for good weather, rain, and ice respectively.
For example, the ETE for the bus route servicing Zone B is computed as 160 + 128 + 30 = 5:20 for good weather (rounded up to nearest 5 minutes). Here, 128 minutes is the time to travel 11.1 miles at 5.2 mph, the average speed output by the model for this route at 160 minutes.
The average single wave ETE (4 hours and 5 minutes) for the transit dependent population does not exceed the 90th percentile ETE for the general population for a winter, midweek, midday, good weather scenario and will not impact protective action decision making.
The ETE for a second wave (discussed below) is presented in the event there is a shortfall of available buses or bus drivers.
Activity: Travel to Reception Centers (EF)
The distances from the EPZ boundary to the reception centers are measured using GIS software along the most likely route from the EPZ exit point to the reception center. The reception centers are mapped in Figure 104. For a onewave evacuation, this travel time outside the EPZ does not contribute to the ETE. Assumed bus speeds of 45 mph, 40 mph, and 35 mph for good weather, rain, and ice, respectively, will be applied for this activity for buses servicing the transit dependent population.
Activity: Passengers Leave Bus (FG)
A bus can empty within 5 minutes. The driver takes a 10minute break.
Activity: Bus Returns to Route for Second Wave Evacuation (GCDE)
The buses assigned to return to the EPZ to perform a second wave evacuation of transit dependent evacuees will be those that have already evacuated transitdependent people who McGuire Nuclear Station                        86                              KLD Engineering, P.C.
Evacuation Time Estimate                                                                      Rev. 0
 
mobilized more quickly. The first wave of transitdependent people depart the bus, and the bus then returns to the EPZ, travels to the start of its route and proceeds to pick up more transit dependent evacuees along the route. The travel time back to the EPZ is equal to the travel time to the reception center.
The second wave ETE for the bus route servicing Zone B is computed as follows for good weather:
* Bus arrives at reception center at 5:29 in good weather (5:20 to exit EPZ + 9minute travel time to reception center).
* Bus discharges passengers (5 minutes) and driver takes a 10minute rest: 15 minutes.
* Bus returns to EPZ and completes second route: 9 minutes (equal to travel time to reception center) + 30 minutes to travel to the start of the route and to rerun the route a second time (11.1 miles @ 45 mph [assumed speed since bus is traveling against traffic] + 11.1 miles @ 42.4 mph [route specific speed output from the model at this time]) = 39 minutes
* Bus completes pickups along route: 30 minutes.
* Bus exits EPZ at time 5:20 + 0:09 + 0:15 + 0:39 + 0:30 = 6:55 (rounded up to nearest 5 minutes) after the ATE.
The ETE for the completion of the second wave for all transitdependent bus routes are provided in Table 85 through Table 87.
The average ETE (5 hours and 35 minutes) for a twowave evacuation of the transitdependent population is 1 hour and 20 minutes longer than the ETE for the general population at the 90th percentile for an evacuation of the entire EPZ (Region R03) under winter, midweek, midday, good weather conditions (Scenario 6) and could impact protective action decision making.
The relocation of transitdependent evacuees from the reception centers to congregate care centers, if the counties decide to do so, is not considered in this study.
Evacuation of Medical Facilities Activity: Mobilize Drivers (ABC)
As discussed in Section 2.4, it is assumed that the mobilization time for medical facilities average 180 minutes in good weather, 190 minutes in rain and 200 minutes in ice. Specially trained medical support staff (working their regular shift) will be on site to assist in the evacuation of patients. Additional staff (if needed) could be mobilized over this same 180minute timeframe.
Activity: Board Passengers (CD)
Item 5 of Section 2.4 discusses transit vehicle loading times for medical facilities. Loading times are assumed to be 1 minute per ambulatory passenger, 5 minutes per wheelchair bound passenger, and 15 minutes per bedridden passenger for buses, wheelchair buses/vans, and ambulances, respectively. Item 3 of Section 2.4 discusses transit vehicle capacities to cap loading times per vehicle type. Concurrent loading on multiple vehicles is also assumed, as stated in item 5 of Section 2.4.

Activity: Travel to EPZ Boundary (DE)
The travel distance along the respective evacuation routes within the EPZ is estimated using the UNITES software. Bus travel times within the EPZ are computed using average speeds computed by DYNEV, using the aforementioned methodology that was used for school, preschool and childcare center evacuation.
Table 88 through Table 810 summarize the ETE for medical facilities within the EPZ for good weather, rain, and ice. Average speeds output by the model for Scenario 6 (Scenario 7 for rain and Scenario 8 for ice) Region 3, capped at 45 mph (40 mph for rain and 35 mph for ice), are used to compute travel time to EPZ boundary. The travel time to the EPZ boundary is computed by dividing the distance to the EPZ boundary by the average travel speed. The ETE is the sum of the mobilization time, total passenger loading time, and travel time out of the EPZ. Concurrent loading on multiple buses, wheelchair buses/vans, and ambulances at capacity is assumed. All ETE are rounded up to the nearest 5 minutes.
For example, the calculation of ETE for the Woodlawn Haven Rest Home with 21 ambulatory residents during good weather is:
ETE: 180 + 1 x 21 + 4 = 205 min. or 3:25 It is assumed that the population at medical facilities is directly evacuated to appropriate host medical facilities. Relocation of this population to permanent facilities and/or passing through the reception center before arriving at the host facility are not considered in this analysis.
The average single wave ETE (4 hours) for medical facilities in the EPZ does not exceed the 90th percentile ETE for the general population for a winter, midweek, midday, good weather scenario and will not impact protective action decision making.
Activity: Vehicles Travel to Host Facilities (EF), Passengers Leave (FG), Vehicle Returns to Route for Second Wave Evacuation (GCDE)
Due to the large number of medical facilities in the EPZ, second wave ETE were not computed for each medical facility. Rather, the following representative ETE is provided to estimate the additional time needed for a second wave evacuation using school buses after the schools, preschools and childcare centers have been evacuated, since there is a shortfall of buses. Times and distances are based on facilitywide averages:
* Buses arrive at host medical facility at 4:13 [4:00 to exit the EPZ + estimated 13minute travel time (average travel time to relocation school/reception center from EPZ boundary; calculated from Table 821)]
* Bus discharges passengers (28 minutes - average ambulatory loading time from Table
: 88) and driver takes a 10minute rest: 38 minutes.
* Bus returns to EPZ and completes second route: 13 minutes to travel back to the EPZ boundary (equal to the average travel time to relocation school/reception center from 1
In the absence of data on the location and capacity of host medical facilities, the average travel time to relocation schools was utilized as an estimate of the time required to travel from the host medical facility back to the medical facility for a second wave evacuation for buses.

EPZ boundary for good weather; from Table 82) + 6 minutes to travel back to the facility (average distance to EPZ - 4.7 miles from Table 88 @ 45 mph) = 19 minutes.
* Remaining ambulatory patients loaded on bus (maximum): 28 minutes (average from Table 88 capped at 30 passengers per bus).
* Bus travels to EPZ boundary: 13 minutes (average distance from hospitals to EPZ boundary (4.7 miles) at 20.8 mph (network wide average speed at 5:40)
* Bus exits EPZ at time 4:13 + 0:38 + 0:19 + 0:28 + 0:13 = 5:55 (rounded up to nearest 5 minutes) after the ATE.
Thus, the second wave evacuation requires an additional 1 hour and 55 minutes (5:55 4:00=1:55). The average ETE for a twowave evacuation of medical facilities exceeds the ETE for the general population at the 90th percentile and will impact protective action decision making since it exceeds the 90th percentile ETE (by 1 hour and 40 minutes) for the general population for a winter, midweek, midday, good weather scenario.
A second wave ETE was not computed for the shortfall of wheelchair buses (as shown in Table
: 81) as there are ample wheelchair vans that could be used to evacuate the wheelchair bound population at the medical facilities in the EPZ.
Evacuation of Correctional Facilities Activity: Mobilize Drivers (ABC)
As discussed in item 4 of Section 2.4, it is assumed that the mobilization time for correctional facilities average 90 minutes in good weather, 100 minutes in rain and 110 minutes in ice.
Activity: Board Passengers (CD)
It is estimated that it takes 20 minutes to load the inmates onto a van during good weather condition (25 minutes in rain, 30 in minutes ice) and that the vans can be loaded in parallel.
Activity: Travel to EPZ Boundary (DE)
As detailed in Table 811, there are one correctional facility within the EPZ - Mecklenburg County Sheriff's Office Jail North. The total inmate population at this facility is 500 persons. As discussed in Section 3.10, a total of 50 vans are needed to evacuate Mecklenburg County Sheriff's Office Jail North. Personnel at the facility stated there are 7 secure vans with an additional 10 secure vans that are currently part of the Sherriffs Office Field Division Fleet. Based on the number of secure vans available and on a capacity of 10 inmates and assuming 2 deputies/officers per van, a multiwave evacuation is necessary. The detailed evacuation plans for this facility is confidential. Using GIS software, the shortest route from the facility to the EPZ boundary, traveling away from the plant, is 1.3 miles.
Times and distances are based on correctional facility in the EPZ for good weather:
The ETE is calculated as follows:
: a. Buses arrive at the correctional facility location: 90 minutes
: b. Load inmates onto the bus: 20 minutes
: c. Travel to EPZ boundary: 25 minutes (1.3 miles at 3.1 mph).

Evacuation Time Estimate                                                                          Rev. 0
 
ETE: 90 + 20 + 25 = 2:15 The average singlewave ETE, for correctional facilities, is less than the 90th percentile ETE for evacuation of the general population in the entire EPZ (Region R03) under winter, midweek, midday, good weather (Scenario 6) conditions and will not impact protective action decision making.
Activity: Vehicles Travel to Host Facilities (EF), Passengers Leave (FG), Vehicle Returns to Route for Second Wave Evacuation (GCDE)
Since there is a shortfall of transportation resources, the vans carrying the inmates from the correctional facility within the EPZ travel to their host facilities, discharge their passengers, and return to gather more inmates from the EPZ. According to the previous ETE study, inmates at this facility would be taken to Downtown Charlotte Facility, Jail Central, on 4th Street and McDowell St. The following outlines the ETE calculations for a second wave:
* Vans arrive at Jail Central (host facility) 2:26 [2:15 to exit the EPZ + estimated 11 minute travel time to Jail Central (8.6 miles distance from EPZ boundary to host facility
            @ 45 mph)]
* Vans discharge inmates (20 minutes) and driver takes a 10minute rest: 30 minutes.
* Vans return to EPZ and completes second route: 11 minutes to travel back to the EPZ boundary from Jail Central + 2 minutes to travel back to the facility (1.3 miles @ 45 mph) = 13 minutes.
* Vans complete pickup at Jail North: 20 minutes
* Vans travel to EPZ boundary: 6 minutes [1.3 miles at 12 mph (network wide average speed at 3:30)]
* Vans exit EPZ at time 2:26 + 0:30 + 0:13 + 0:20 + 0:06 = 3:35 (rounded up to nearest 5 minutes) after the ATE.
Thus, the second wave evacuation requires an additional 1 hours and 20 minutes (3:35 2:15=1:20). The average ETE for a twowave evacuation of correctional facility does not exceed the 90th percentile ETE for the general population for a winter, midweek, midday, good weather scenario (Scenario 6) and is not likely to impact protective action decision making.
8.2  ETE for Access and/or Functional Needs Population The special needs population registered within the EPZ was provided by offsite agencies. Table 812 summarizes the ETE for access and/or functional needs people who would need transportation assistance in the event of an emergency. The table is categorized by type of vehicle required and then broken down by weather condition. The table takes into consideration the deployment of multiple vehicles (not filled to capacity) to reduce the number of stops per vehicle. Due to the limitations on driving for access and/or functional needs persons, it assumed they will be picked up from their homes. Furthermore, it is conservatively assumed that ambulatory and wheelchair bound access and/or functional needs households are spaced 3 miles apart and bedridden households are spaced 5 miles apart. Van and bus speeds approximate 20 mph between households and ambulance speeds approximate 30 mph in good weather (10%

slower in rain, 20% slower in ice). Mobilization times of 160 minutes were used (170 minutes for rain, and 180 minutes for ice). The last household (HH) is assumed to be 5 miles from the EPZ boundary, and the networkwide average speed, capped at 45 mph (40 mph for rain and 35 mph for ice), after the last pickup is used to compute travel time.
ETE is computed by summing mobilization time, loading time at first household, travel to subsequent households, loading time at subsequent households, and travel time to EPZ boundary. All ETE are rounded to the nearest 5 minutes.
For example, assuming no more than one access and/or functional needs person per HH implies that 334 ambulatory households need to be serviced. While only 12 buses are needed from a capacity perspective, if 17 buses are deployed to service these HH, then each would require at most 20 stops, otherwise it would be 28 stops if we only deploy 12 buses. The following outlines the ETE calculations:
: 1. Assume 17 buses are deployed, each with about 20 stops, to service a total of 334 HH.
: 2. The ETE is calculated as follows:
: a. Buses arrive at the first pickup location: 160 minutes
: b. Load HH members at first pickup: 1 minutes
: c. Travel to subsequent pickup locations: 19 (201) @ 9 minutes = 171 minutes
: d. Load HH members at subsequent pickup locations: 19 (201) @ 1 minutes = 19 minutes
: e. Travel to EPZ boundary: 14 minutes (5 miles at 21 mph).
ETE: 160 + 1 + 171 + 19 + 14 = 365 minutes or 6:05 The average ETE of a firstwave evacuation of the ambulatory access and/or functional needs population exceeds the general population ETE at the 90th percentile by 1 hour and 50 minutes (6:054:15 = 1:50) for an evacuation of the entire EPZ (Region R03), during Scenario 6 condition and could impact protective action decision making.
The following outlines the ETE calculations of a second wave needed using school buses after the schools, preschools childcare centers have been evacuated (see Table 813):
: a. School buses arrive at reception center/relocation school: 3:20 (average value from Table 82)
: b. Unload students at pickup point: 5 minutes.
: c. Driver takes 10minute rest: 10 minutes.
: d. Travel time back to EPZ: 13 minutes (average time of Travel Time from EPZ Bdry to RS/RC from Table 82)
: e. Travel to first household: 9 minutes (3 miles @ 20 mph)
: f. Loading time at first household: 1 minutes
: g. Travel to subsequent pickup locations: 19 @ 9 minutes = 171 minutes or 2:51
: h. Loading time at subsequent households: 19 stops @ 1 minutes = 19 minutes
: i. Travel time to EPZ boundary at 5 miles @ 12.5 mph = 24 minutes ETE: 3:20 + 0:05 + 0:10 + 0:13 + 0:09 + 0:01 + 2:51 + 0:19 + 0:24 = 7:35 (rounded up to nearest 5 minutes)

9    TRAFFIC MANAGEMENT STRATEGY This section discusses the suggested Traffic Management Plan (TMP) that is designed to expedite the movement of evacuating traffic. The resources required to implement this strategy include:
* Personnel with the capabilities of performing the planned control functions of traffic guides (preferably, not necessarily, law enforcement officers).
* Guidance is provided by the Manual on Uniform Traffic Control Devices (MUTCD) published by the Federal Highway Administration (FHWA) of the U.S.D.O.T. All state and most county transportation agencies have access to the MUTCD, which is available on line: http://mutcd.fhwa.dot.gov which provides access to the official PDF version.
* The All County Standard Operating Guideline (SOG) for Traffic Control Point and Security Road Block Operations in Support of the McGuire Nuclear Station, dated January 2019, which defines all Traffic Control Point (TCP) and Security Road Block (SRB) locations, provides necessary details and is documented in a format that is readily understood by those assigned to perform traffic control.
The functions to be performed in the field are:
: 1. Facilitate evacuating traffic movements that safely expedite travel out of the EPZ.
: 2. Discourage traffic movements that move evacuating vehicles in a direction which takes them significantly closer to the power plant, or which interferes with the efficient flow of other evacuees.
The terms "facilitate" and "discourage" are employed rather than "enforce" and "prohibit" to indicate the need for flexibility in performing the traffic control function. There are always legitimate reasons for a driver to prefer a direction other than that indicated.
For example:
* A driver may be traveling home from work or from another location, to join other family members prior to evacuating.
* An evacuating driver may be travelling to pick up a relative, or other evacuees.
* The driver may be an emergency worker en route to perform an important activity.
The implementation of a TMP must also be flexible enough for the application of sound judgment by the traffic guide.
The TMP is the outcome of the following process:
: 1. The existing TCPs and SRBs identified by the All County SOG serves as the basis of the traffic management plan, as per NUREG/CR7002, Rev. 1.
: 2. Evacuation simulations were run using DYNEV II to predict traffic congestion during evacuation (see Section 7.3 and Figures 73 through 710).

Evacuation Time Estimate                                                                      Rev. 0
: 3. These simulations help to identify the best routing and critical intersections that experience pronounced congestion during evacuation. Modifications to the existing TCP and/or SRB locations that would improve congestion and the ETE were analyzed. See Appendix G for more additional information.
: 4. The TCPs and SRBs defined in the existing TMP, the recommended modified TCP/SRBs and how they were applied in this study, are listed in Appendix K and discussed in Appendix G, respectively.
: 5. Prioritization of TCPs and SRBs.
: a. Application of traffic and access control at some TCPs and SRBs will have a more pronounced influence on expediting traffic movements than at other TCPs and SRBs. For example, TCPs controlling traffic originating from areas in close proximity to the power plant could have a more beneficial effect on minimizing potential exposure to radioactivity than those TCPs located far from the power plant. These priorities should be assigned by state/county emergency management representatives and by law enforcement personnel.
Appendix G documents the existing TMP and modified TCPs using the process enumerated above.
9.1    Assumptions The ETE calculations documented in Section 7 and 8 assume that the traffic management plan is implemented during evacuation and the modifications discussed in Appendix G are in place.
The ETE calculations reflect the assumptions that all externalexternal trips are interdicted and diverted after 2 hours have elapsed from the Advisory to Evacuate (ATE).
All transit vehicles and other responders entering the EPZ to support the evacuation are assumed to be unhindered by personal manning TCPs and SRBs.
Study assumptions 1 and 2 in Section 2.5 discuss TCP and SRB operations.
9.2    Additional Considerations The use of Intelligent Transportation Systems (ITS) technologies can reduce the manpower and equipment needs, while still facilitating the evacuation process. Dynamic Message Signs (DMS) can be placed within the EPZ to provide information to travelers regarding traffic conditions, route selection, and reception/care center information. DMS placed outside of the EPZ will warn motorists to avoid using routes that may conflict with the flow of evacuees away from the power plant. Highway Advisory Radio (HAR) can be used to broadcast information to evacuees during egress through their vehicles stereo systems. Automated Travel Information Systems (ATIS) can also be used to provide evacuees with information. Internet websites can provide traffic and evacuation route information before the evacuee begins their trip, while the on board navigation systems (GPS units) and smartphones can be used to provide information during evacuation trip.

These are only some examples of how ITS technologies can benefit the evacuation process.
Considerations should be given that ITS technologies can be used to facilitate the evacuation process, and any additional signage placed should consider evacuation needs.

10 EVACUATION ROUTES AND RECEPTION CENTERS 10.1 Evacuation Routes Evacuation routes are comprised of two distinct components:
* Routing from a Zone being evacuated to the boundary of the Evacuation Region and thence out of the EPZ.
* Routing of transitdependent evacuees (schools, preschools, childcare centers, medical facilities, correctional facilities, and residents who do not own or have access to a private vehicle) from the EPZ boundary to reception centers and/or relocation schools.
Evacuees will select routes within the EPZ in such a way as to minimize their exposure to risk.
This expectation is met by the DYNEV II model routing traffic away from the location of the plant to the extent practicable. The DTRAD model satisfies this behavior by routing traffic so as to balance traffic demand relative to the available highway capacity to the extent possible. See Appendices B through D for further discussion.
The major evacuation routes for the EPZ are presented in Figure 101. These routes will be used by the general population evacuating in private vehicles, and by the transitdependent population evacuating in buses. Transitdependent evacuees will be routed to reception centers. School buses will be routed to relocation schools. General population may evacuate to either a reception center or some alternate destination (e.g., lodging facilities, relatives home, campgrounds) outside the EPZ.
The routing of transitdependent evacuees from the EPZ boundary to reception centers is designed to minimize the amount of travel outside the EPZ, from the points where these routes cross the EPZ boundary. The 19 bus routes shown graphically in Figure 102 and Figure 103 and described in Table 101 were designed by KLD to service the major evacuation routes through each Zone for this study, in order to compute ETE. It is assumed that residents will walk to and congregate along the major evacuation routes to flag down a bus, and that they can arrive at the roadway within the 160minute bus mobilization time (good weather).
Schools, preschools, childcare centers, medical facilities and correctional facilities were routed along the most likely path from the facility being evacuated to the EPZ boundary, traveling toward the appropriate relocation school or reception centers. For Lincoln County, outlined evacuation route maps for schools, child and adult care facilities from 2018 Standard Operating Guideline (SOG) were followed. The McGuire Nuclear Station (MNS) 2022 Emergency Preparedness Information1 lists many of the major schools and specifies their relocation school.
For schools not listed in the plan, reception center which designated based on which Zone the school located was assumed and most likely path for evacuation to the EPZ boundary was selected. This study does not consider the transport of evacuees from reception centers to congregate care centers if the counties do make the decision to relocate evacuees.

The specified bus routes for all the transitdependent population are documented in Table 102 (refer to the maps of the linknode analysis network in Appendix K for node locations).
10.2 Reception Centers According to the MNS 2022 Emergency Preparedness Information1, evacuees living in Zones C, D, E, and F will be directed to UNC Charlotte as their reception center. Evacuees living in Zones A, H, I, and J will be directed to South Iredell High School. Evacuees living in Zones B and G will be directed to Northwest Cabarrus Middle School. Evacuees living in Gaston County (Zones R and S) will be directed to Stuart Cramer High School. Evacuees living in Lincoln County (Zones L, M, N, O, P, and Q) will be directed to Lincolnton High School and/or West Lincoln High School.
Evacuees in Catawba County (Zone K) will be directed to Mill Creek Middle School.
As previously discussed, the MNS 2022 Emergency Preparedness Information lists the relocation schools and reception centers. Table 103 presents a list of the relocation schools for each school in the EPZ. It is assumed that all school, preschool, and childcare center evacuees will be taken to the appropriate relocation school (or reception center, if none was specified) and will be subsequently picked up by parents or guardians.
Figure 104 show the primary general reception centers and relocation school for evacuees.
Transitdependent evacuees are routed to the nearest reception center for each Zone for ETE computations.

APPENDIX B DTRAD: Dynamic Traffic Assignment and Distribution Model
 
B.      DYNAMIC TRAFFIC ASSIGNMENT AND DISTRIBUTION MODEL This appendix describes the integrated dynamic trip assignment and distribution model named DTRAD (Dynamic TRaffic Assignment and Distribution) that is expressly designed for use in analyzing evacuation scenarios. DTRAD employs logitbased pathchoice principles and is one of the models of the DYNEV II Model. The DTRAD module implements pathbased Dynamic Traffic Assignment (DTA) so that time dependent OriginDestination (OD) trips are assigned to routes over the network based on prevailing traffic conditions.
To apply the DYNEV II Model, the analyst must specify the highway network, link capacity information, the timevarying volume of traffic generated at all origin centroids and, optionally, a set of accessible candidate destination nodes on the periphery of the Emergency Planning Zone (EPZ) for selected origins. DTRAD calculates the optimal dynamic trip distribution (i.e., trip destinations) and the optimal dynamic trip assignment (i.e., trip routing) of the traffic generated at each origin node traveling to its set of candidate destination nodes, so as to minimize evacuee travel cost.
B.1    Overview of Integrated Distribution and Assignment Model The underlying premise is that the selection of destinations and routes is intrinsically coupled in an evacuation scenario. That is, people in vehicles seek to travel out of an area of potential risk as rapidly as possible by selecting the best routes. The model is designed to identify these best routes in a manner that realistically distributes vehicles from origins to destinations and routes them over the highway network, in a consistent and optimal manner, reflecting evacuee behavior.
For each origin, a set of candidate destination nodes is selected by the software logic and by the analyst to reflect the desire by evacuees to travel away from the power plant and to access major highways. The specific destination nodes within this set that are selected by travelers and the selection of the connecting paths of travel, are both determined by DTRAD. This determination is made by a logitbased path choice model in DTRAD, so as to minimize the trip cost, as discussed later.
The traffic loading on the network and the consequent operational traffic environment of the network (density, speed, throughput on each link) vary over time as the evacuation takes place.
The DTRAD model, which is interfaced with the DYNEV simulation model, executes a succession of sessions wherein it computes the optimal routing and selection of destination nodes for the conditions that exist at that time.
B.2    Interfacing the DYNEV Simulation Model with DTRAD The DYNEV II model reflects NRC guidance that evacuees will seek to travel in a general direction away from the location of the hazardous event. An algorithm was developed to support the DTRAD model in dynamically varying the Trip Table (OD matrix) over time from one DTRAD session to the next. Another algorithm executes a mapping from the specified McGuire Nuclear Station                        B1                              KLD Engineering, P.C.

geometric network (linknode analysis network) that represents the physical highway system, to a path network that represents the vehicle [turn] movements. DTRAD computations are performed on the path network: DYNEV simulation model, on the geometric network.
B.2.1 DTRAD Description DTRAD is the DTA module for the DYNEV II Model.
When the road network under study is large, multiple routing options are usually available between trip origins and destinations. The problem of loading traffic demands and propagating them over the network links is called Network Loading and is addressed by DYNEV II using macroscopic traffic simulation modeling. Traffic assignment deals with computing the distribution of the traffic over the road network for given OD demands and is a model of the route choice of the drivers. Travel demand changes significantly over time, and the road network may have time dependent characteristics, e.g., timevarying signal timing or reduced road capacity because of lane closure, or traffic congestion. To consider these time dependencies, DTA procedures are required.
The DTRAD DTA module represents the dynamic route choice behavior of drivers, using the specification of dynamic origindestination matrices as flow input. Drivers choose their routes through the network based on the travel cost they experience (as determined by the simulation model). This allows traffic to be distributed over the network according to the timedependent conditions. The modeling principles of DTRAD include:
It is assumed that drivers not only select the best route (i.e., lowest cost path) but some also select less attractive routes. The algorithm implemented by DTRAD archives several efficient routes for each OD pair from which the drivers choose.
The choice of one route out of a set of possible routes is an outcome of discrete choice modeling. Given a set of routes and their generalized costs, the percentages of drivers that choose each route is computed. The most prevalent model for discrete choice modeling is the logit model. DTRAD uses a variant of PathSizeLogit model (PSL). PSL overcomes the drawback of the traditional multinomial logit model by incorporating an additional deterministic path size correction term to address path overlapping in the random utility expression.
DTRAD executes the traffic assignment (TA) algorithm on an abstract network representation called "the path network" which is built from the actual physical link node analysis network. This execution continues until a stable situation is reached: the volumes and travel times on the edges of the path network do not change significantly from one iteration to the next. The criteria for this convergence are defined by the user.
Travel cost plays a crucial role in route choice. In DTRAD, path cost is a linear summation of the generalized cost of each link that comprises the path. The generalized cost for a link, a, is expressed as ca  ta  la  sa ,

where ca is the generalized cost for link a, and  ,  , and  are cost coefficients for link travel time, distance, and supplemental cost, respectively. Distance and supplemental costs are defined as invariant properties of the network model, while travel time is a dynamic property dictated by prevailing traffic conditions. The DYNEV simulation model computes travel times on all edges in the network and DTRAD uses that information to constantly update the costs of paths. The route choice decision model in the next simulation iteration uses these updated values to adjust the route choice behavior. This way, traffic demands are dynamically reassigned based on time dependent conditions.
The interaction between the DTRAD traffic assignment and DYNEV II simulation models is depicted in Figure 01. Each round of interaction is called a Traffic Assignment Session (TA session). A TA session is composed of multiple iterations, marked as loop B in the figure.
The supplemental cost is based on the survival distribution (a variation of the exponential distribution).The Inverse Survival Function is a cost term in DTRAD to represent the potential risk of travel toward the plant:
sa =  ln (p), 0  p  l ;  0 p=
dn = Distance of node, n, from the plant d0 =Distance from the plant where there is zero risk
          = Scaling factor The value of do = 10 miles, the outer distance of the EPZ. Note that the supplemental cost, sa, of link, a, is (high, low), if its downstream node, n, is (near, far from) the power plant.

B.2.2 Network Equilibrium In 1952, John Wardrop wrote:
Under equilibrium conditions traffic arranges itself in congested networks in such a way that no individual tripmaker can reduce his path costs by switching routes.
The above statement describes the User Equilibrium definition, also called the Selfish Driver Equilibrium. It is a hypothesis that represents a [hopeful] condition that evolves over time as drivers search out alternative routes to identify those routes that minimize their respective costs. It has been found that this equilibrium objective to minimize costs is largely realized by most drivers who routinely take the same trip over the same network at the same time (i.e.,
commuters). Effectively, such drivers learn which routes are best for them over time. Thus, the traffic environment settles down to a nearequilibrium state.
Clearly, since an emergency evacuation is a sudden, unique event, it does not constitute a long term learning experience which can achieve an equilibrium state. Consequently, DTRAD was not designed as an equilibrium solution, but to represent drivers in a new and unfamiliar situation, who respond in a flexible manner to realtime information (either broadcast or observed) in such a way as to minimize their respective costs of travel.

APPENDIX C DYNEV Traffic Simulation Model
 
C. DYNEV TRAFFIC SIMULATION MODEL This appendix describes the DYNEV traffic simulation model. The DYNEV traffic simulation model is a macroscopic model that describes the operations of traffic flow in terms of aggregate variables: vehicles, flow rate, mean speed, volume, density, queue length, on each link, for each turn movement, during each Time Interval (simulation time step). The model generates trips from sources and from Entry Links and introduces them onto the analysis network at rates specified by the analyst based on the mobilization time distributions. The model simulates the movements of all vehicles on all network links over time until the network is empty. At intervals, the model outputs Measures of Effectiveness (MOE) such as those listed in Table C1.
Model Features Include:
Explicit consideration is taken of the variation in density over the time step; an iterative procedure is employed to calculate an average density over the simulation time step for the purpose of computing a mean speed for moving vehicles.
Multiple turn movements can be serviced on one link; a separate algorithm is used to estimate the number of (fractional) lanes assigned to the vehicles performing each turn movement, based, in part, on the turn percentages provided by the Dynamic TRaffic Assignment and Distribution (DTRAD) model.
At any point in time, traffic flow on a link is subdivided into two classifications: queued and moving vehicles. The number of vehicles in each classification is computed. Vehicle spillback, stratified by turn movement for each network link, is explicitly considered and quantified. The propagation of stopping waves from link to link is computed within each time step of the simulation. There is no vertical stacking of queues on a link.
Any link can accommodate source flow from zones via side streets and parking facilities that are not explicitly represented. This flow represents the evacuating trips that are generated at the source.
The relation between the number of vehicles occupying the link and its storage capacity is monitored every time step for every link and for every turn movement. If the available storage capacity on a link is exceeded by the demand for service, then the simulator applies a metering rate to the entering traffic from both the upstream feeders and source node to ensure that the available storage capacity is not exceeded.
A path network that represents the specified traffic movements from each network link is constructed by the model; this path network is utilized by the DTRAD model.
A twoway interface with DTRAD: (1) provides link travel times; (2) receives data that translates into link turn percentages.
Provides MOE to animation software, EVAN (EVacuation ANimator)
Calculates ETE statistics All traffic simulation models are data intensive. Table C2 outlines the necessary input data elements.
To provide an efficient framework for defining these specifications, the physical highway environment is represented as a network. The unidirectional links of the network represent McGuire Nuclear Station                          C1                              KLD Engineering, P.C.

roadway sections: rural, multilane, urban streets or freeways. The nodes of the network generally represent intersections or points along a section where a geometric property changes (e.g. a lane drop, change in grade or free flow speed).
Figure C1 is an example of a small network representation. The freeway is defined by the sequence of links, (20,21), (21,22), and (22,23). Links (8001, 19) and (3, 8011) are Entry and Exit links, respectively. An arterial extends from node 3 to node 19 and is partially subsumed within a grid network. Note that links (21,22) and (17,19) are gradeseparated.
C.1    Methodology C.1.1 The Fundamental Diagram It is necessary to define the fundamental diagram describing flowdensity and speeddensity relationships. Rather than settling for a triangular representation, a more realistic representation that includes a capacity drop, (IR)Qmax, at the critical density when flow conditions enter the forced flow regime, is developed and calibrated for each link. This representation, shown in Figure C2, asserts a constant free speed up to a density, k , and then a linear reduction in speed in the range, k        k k        45 vpm, the density at capacity. In the flowdensity plane, a quadratic relationship is prescribed in the range, k          k        95 vpm which roughly represents the stopandgo condition of severe congestion. The value of flow rate, Q , corresponding to k , is approximated at 0.7 RQ                    . A linear relationship between k and k completes the diagram shown in Figure C2. Table C3 is a glossary of terms.
The fundamental diagram is applied to moving traffic on every link. The specified calibration values for each link are: (1) Free speed, v ; (2) Capacity, Q            ; (3) Critical density, k 45 vpm ; (4) Capacity Drop Factor, R = 0.9 ; (5) Jam density, k . Then, v                  , k    k
          . Setting k    k    k , then Q      RQ              k for 0      k    k    50 . It can be shown that Q        0.98    0.0056 k RQ        for k    k    k , where k    50 and k      175.
C.1.2 The Simulation Model The simulation model solves a sequence of unit problems. Each unit problem computes the movement of traffic on a link, for each specified turn movement, over a specified time interval (TI) which serves as the simulation time step for all links. Figure C3 is a representation of the unit problem in the timedistance plane. Table C3 is a glossary of terms that are referenced in the following description of the unit problem procedure.
The formulation and the associated logic presented below are designed to solve the unit problem for each sweep over the network (discussed below), for each turn movement serviced on each link that comprises the evacuation network, and for each TI over the duration of the evacuation.

The complete Algorithm A considers all flow scenarios; space limitation precludes its inclusion, here.
C.1.3 Lane Assignment The unit problem is solved for each turn movement on each link. Therefore, it is necessary to calculate a value, LN , of allocated lanes for each movement, x. If in fact all lanes are specified by, say, arrows painted on the pavement, either as full lanes or as lanes within a turn bay, then the problem is fully defined. If however there remain unchannelized lanes on a link, then an analysis is undertaken to subdivide the number of these physical lanes into turn movement specific virtual lanes, LNx.
C.2    Implementation C.2.1 Computational Procedure The computational procedure for this model is shown in the form of a flow diagram as Figure C4. As discussed earlier, the simulation model processes traffic flow for each link independently over TI that the analyst specifies; it is usually 60 seconds or longer. The first step is to execute an algorithm to define the sequence in which the network links are processed so that as many links as possible are processed after their feeder links are processed, within the same network sweep. Since a general network will have many closed loops, it is not possible to guarantee that every link processed will have all of its feeder links processed earlier.
The processing then continues as a succession of time steps of duration, TI, until the simulation is completed. Within each time step, the processing performs a series of sweeps over all network links; this is necessary to ensure that the traffic flow is synchronous over the entire network. Specifically, the sweep ensures continuity of flow among all the network links; in the context of this model, this means that the values of E, M, and S are all defined for each link such that they represent the synchronous movement of traffic from each link to all of its outbound links. These sweeps also serve to compute the metering rates that control spillback.
Within each sweep, processing solves the unit problem for each turn movement on each link.
With the turn movement percentages for each link provided by the DTRAD model, an algorithm allocates the number of lanes to each movement serviced on each link. The timing at a signal, if any, applied at the downstream end of the link, is expressed as a G/C ratio, the signal timing needed to define this ratio is an input requirement for the model. The model also has the capability of representing, with macroscopic fidelity, the actions of actuated signals responding to the timevarying competing demands on the approaches to the intersection.
The solution of the unit problem yields the values of the number of vehicles, O, that discharge from the link over the time interval and the number of vehicles that remain on the link at the end of the time interval as stratified by queued and moving vehicles: Q and M . The procedure considers each movement separately (multipiping). After all network links are processed for a given network sweep, the updated consistent values of entering flows, E; metering rates, M; and source flows, S are defined so as to satisfy the no spillback condition.

The procedure then performs the unit problem solutions for all network links during the following sweep.
Experience has shown that the system converges (i.e. the values of E, M and S settle down for all network links) in just two sweeps if the network is entirely undersaturated or in four sweeps in the presence of extensive congestion with link spillback. (The initial sweep over each link uses the final values of E and M, of the prior TI). At the completion of the final sweep for a TI, the procedure computes and stores all measures of effectiveness for each link and turn movement for output purposes. It then prepares for the following time interval by defining the values of Q and M for the start of the next TI as being those values of Q and M at the end of the prior TI. In this manner, the simulation model processes the traffic flow over time until the end of the run. Note that there is no spacediscretization other than the specification of network links.
C.2.2 Interfacing with Dynamic Traffic Assignment (DTRAD)
The DYNEV II system reflects NRC guidance that evacuees will seek to travel in a general direction away from the location of the hazardous event. Thus, an algorithm was developed to identify an appropriate set of destination nodes for each origin based on its location and on the expected direction of travel. This algorithm also supports the DTRAD model in dynamically varying the Trip Table (OD matrix) over time from one DTRAD session to the next.
Figure B1 depicts the interaction of the simulation model with the DTRAD model in the DYNEV II system. As indicated, DYNEV II performs a succession of DTRAD sessions; each such session computes the turn link percentages for each link that remain constant for the session duration, T , T , specified by the analyst. The end product is the assignment of traffic volumes from each origin to paths connecting it with its destinations in such a way as to minimize the networkwide cost function. The output of the DTRAD model is a set of updated link turn percentages which represent this assignment of traffic.
As indicated in Figure B1, the simulation model supports the DTRAD session by providing it with operational link MOE that are needed by the path choice model and included in the DTRAD cost function. These MOE represent the operational state of the network at a time, T    T , which lies within the session duration, T , T . This burn time, T              T , is selected by the analyst. For each DTRAD iteration, the simulation model computes the change in network operations over this burn time using the latest set of link turn percentages computed by the DTRAD model. Upon convergence of the DTRAD iterative procedure, the simulation model accepts the latest turn percentages provided by the Dynamic Traffic Assignment (DTA) model, returns to the origin time, T , and executes until it arrives at the end of the DTRAD session duration at time, T . At this time the next DTA session is launched and the whole process repeats until the end of the DYNEV II run.

APPENDIX D Detailed Description of Study Procedure
 
D. DETAILED DESCRIPTION OF STUDY PROCEDURE This appendix describes the activities that were performed to compute Evacuation Time Estimates (ETE). The individual steps of this effort are represented as a flow diagram in Figure D1. Each numbered step in the description that follows corresponds to the numbered element in the flow diagram.
Step 1 The first activity was to verify Emergency Planning Zone (EPZ) boundary information and create a Geographic Information System (GIS) base map. The base map extends beyond the Shadow Region which extends approximately 15 miles (radially) from the power plant location. The base map incorporates the local roadway topology, a suitable topographic background and the EPZ and Zone boundaries.
Step 2 The 2020 Census block population information was obtained in GIS format. This information was used to estimate the permanent resident population within the EPZ and Shadow Region and to define the spatial distribution and demographic characteristics of the population within the study area. Estimates of employees who reside outside the EPZ and commute to work within the EPZ are based on the 2018 Workplace Area Characteristic (WAC) data from the OnTheMap Census analysis tool1 extrapolated to 2020 using the shortterm employment projection for the State of North Carolina2. Transient, school, medical, and other types of special facility data were obtained from the counties within EPZ, the National Center for Education Statistics website3, the North Carolina Division of Child Development and Early Education4, the Health Resources and Services Administration5, the NC Department of Health and Human Services6 and the old data from the previous ETE study, supplemented by internet searches and aerial imagery for where data was missing.
Step 3 A kickoff meeting was conducted with major stakeholders (state and county emergency officials and onsite and offsite Duke Energy personnel). The purpose of the kickoff meeting was to present an overview of the work effort, identify key agency personnel, and indicate the data requirements for the study. Specific requests for information were presented to the state and county emergency officials. Unique features of the study area were discussed to identify the local concerns that should be addressed by the ETE study.

Step 4 Next, a physical survey of the roadway system in the study area was conducted to determine any changes to the roadway network since the previous study. This survey included consideration of the geometric properties of the highway sections, the channelization of lanes on each section of roadway, whether there are any turn restrictions or special treatment of traffic at intersections, the type and functioning of traffic control devices, gathering signal timings for pretimed traffic signals (if any exist within the study area), and to make the necessary observations needed to estimate realistic values of roadway capacity. Roadway characteristics were also verified using aerial imagery.
Step 5 An online demographic survey of the households within the EPZ was conducted to identify household dynamics, trip generation characteristics, and evacuationrelated demographic information of the EPZ population. This information was used to determine important study factors including the average number of evacuating vehicles used by each household, and the time required to perform preevacuation mobilization activities.
Step 6 A computerized representation of the physical roadway system, called a linknode analysis network, was updated using the most recent UNITES software (see Section 1.3 and Appendix K) developed by KLD. Once the updated geometry of the network was completed, the network was calibrated using the information gathered during the road survey (Step 4) and information obtained from aerial imagery. Estimates of highway capacity for each link and other link specific characteristics were introduced to the network description. Traffic signal timings were input accordingly. The linknode analysis network was imported into a GIS map. The 2020 permanent resident population estimates (Step 2) were overlaid in the map, and origin centroids where trips would be generated during the evacuation process were assigned to appropriate links.
Step 7 The EPZ is subdivided into 19 Zones. Based on wind direction and speed, Regions (groupings of Zones) that may be advised to evacuate, were developed.
The need for evacuation can occur over a range of seasonal and weatherrelated conditions.
Scenarios were developed to capture the variation in evacuation demand for different time of day, day of the week, time of year, and weather conditions.
Step 8 The input stream for the DYNEV II system, which integrates the dynamic traffic assignment and distribution model, DTRAD, with the evacuation simulation model, was created for a prototype evacuation case - the evacuation of the entire EPZ for a representative scenario.

Evacuation Time Estimate                                                                    Rev. 0
 
Step 9 After creating this input stream, the DYNEV II Model was executed on the prototype evacuation case to compute evacuating traffic routing patterns consistent with the appropriate NRC guidelines. DYNEV II contains an extensive suite of data diagnostics which check the completeness and consistency of the input data specified. The analyst reviews all warning and error messages produced by the model and then corrects the database to create an input stream that properly executes to completion.
The model assigns destinations to all origin centroids consistent with a (general) radial evacuation of the EPZ and Shadow Region. The analyst may optionally supplement and/or replace these modelassigned destinations, based on professional judgment, after studying the topology of the analysis highway network. The model produces link and networkwide measures of effectiveness as well as estimates of evacuation time.
Step 10 The results generated by the prototype evacuation case are critically examined. The examination includes observing the animated graphics (using the EVAN software  see Section 1.3) produced by DYNEV II and reviewing the statistics output by the model. This is a labor intensive activity, requiring the direct participation of skilled engineers who possess the necessary practical experience to interpret the results and to determine the causes of any problems reflected in the results.
Essentially, the approach is to identify those bottlenecks in the network that represent locations where congested conditions are pronounced and to identify the cause of this congestion. This cause can take many forms, either as excess demand due to high rates of trip generation, improper routing, a shortfall of capacity, or as a quantitative flaw in the way the physical system was represented in the input stream. This examination leads to one of two conclusions:
The results are satisfactory; or The input stream must be modified accordingly.
This decision requires, of course, the application of the user's judgment and experience based upon the results obtained in previous applications of the model and a comparison of the results of the latest prototype evacuation case iteration with the previous ones. If the results are satisfactory in the opinion of the user, then the process continues with Step 13. Otherwise, proceed to Step 11.
Step 11 There are many "treatments" available to the user in resolving apparent problems. These treatments range from decisions to reroute the traffic by assigning additional evacuation destinations for one or more sources, imposing turn restrictions where they can produce significant improvements in capacity, changing the control treatment at critical intersections so as to provide improved service for one or more movements, adding routes (which are paved and traversable) that were not previously modelled but may assist in an evacuation and McGuire Nuclear Station                        D3                            KLD Engineering, P.C.
Evacuation Time Estimate                                                                    Rev. 0
 
increase the available roadway network capacity, or in prescribing specific treatments for channelizing the flow so as to expedite the movement of traffic along major roadway systems.
Such "treatments" take the form of modifications to the original prototype evacuation case input stream. All treatments are designed to improve the representation of evacuation behavior.
Step 12 As noted above, the changes to the input stream must be implemented to reflect the modifications undertaken in Step 11. At the completion of this activity, the process returns to Step 9 where the DYNEV II Model is again executed.
Step 13 Evacuation of transitdependent and special facilities are included in the evacuation analysis.
Fixed routing for transit buses, school buses, ambulances, vans, and other transit vehicles are introduced into the final prototype evacuation case data set. DYNEV II generates routespecific speeds, over time, for use in the estimation of evacuation times for the transit dependent and special facility population groups.
Step 14 The prototype evacuation case was used as the basis for generating all region and scenario specific evacuation cases to be simulated. This process was automated through the UNITES user interface. For each specific case, the population to be evacuated, the trip generation distributions, the highway capacity and speeds, and other factors are adjusted to produce a customized casespecific data set.
Step 15 All evacuation cases are executed using the DYNEV II Model to compute ETE. Once results are available, quality control procedures are used to assure the results are consistent, dynamic routing is reasonable, and traffic congestion/bottlenecks are addressed properly.
Step 16 Once vehicular evacuation results are accepted, average travel speeds for transit and special facility routes are used to compute ETE for transitdependent permanent residents, schools, medical facilities, and other special facilities.
Step 17 The simulation results are analyzed, tabulated and graphed. Traffic management plans are analyzed, and traffic control points are prioritized, if applicable. Additional analysis is conducted to identify the sensitivity of the ETE to changes in some base evacuation conditions and model assumptions. The results are then documented, as required by NUREG/CR7002, Rev. 1.

APPENDIX F Demographic Survey
 
F. DEMOGRAPHIC SURVEY F.1  Introduction The development of evacuation time estimates for the MNS EPZ requires the identification of travel patterns, car ownership and household size of the population within the EPZ. Demographic information can be obtained from Census data; however, the use of this data has several limitations when applied to emergency planning. First, the Census data do not encompass the range of information needed to identify the time required for preliminary activities (mobilization) that must be undertaken prior to evacuating the area. Secondly, Census data do not contain attitudinal responses needed from the population of the EPZ and consequently may not accurately represent the anticipated behavioral characteristics of the evacuating populace.
These concerns are addressed by conducting a demographic survey of a representative sample of the EPZ population. The survey is designed to elicit information from the public concerning family demographics and estimates of response times to well defined events. The design of the survey includes a limited number of questions of the form What would you do if ? and other questions regarding activities with which the respondent is familiar (How long does it take you to ?)
F.2  Survey Instrument and Sampling Plan Attachment A presents the final survey instrument used in this survey. A draft of the instrument was submitted to stakeholders for comment. Comments were received and the survey instrument was modified accordingly, prior to conducting the survey.
Following the completion of the instrument, a sampling plan was developed. Since the demographic survey discussed herein was performed in 2021 prior to the release of the 2020 Census data, 2010 Census data was used to develop the sampling plan.
The sample must be drawn from the EPZ population. Consequently, a list of zip codes in the EPZ was developed using GIS software. This list is shown in Table F1. Along with each zip code, an estimate of the population and number of households in each area was determined by overlaying 2010 Census data and the EPZ boundary, again using GIS software. The proportional percentage of desired completed survey interviews for each area was identified, as shown in Table F1. A sample size of approximately 268 completed household survey forms was obtained, and yields results with a sampling error of +/-5.98% at the 95% confidence level for the number of households in the EPZ according to the 2020 Census. The number of samples obtained from each zip code is also shown in Table F1.
F.3  Survey Results The results of the survey fall into two categories. First, the household demographics of the area can be identified. Demographic information includes such factors as household size, automobile ownership, and automobile availability. The distributions of the time to perform certain pre McGuire Nuclear Station                          F1                            KLD Engineering, P.C.

evacuation activities are the second category of survey results. These data are processed to develop the trip generation distributions used in the evacuation modeling effort, as discussed in Section 5.
A review of the survey instrument reveals that several questions have a decline to state entry for a response. It is accepted practice in conducting surveys of this type to accept the answers of a respondent who offers a decline to state response for a few questions or who refuses to answer a few questions. To address the issue of occasional decline to state responses from a large sample, the practice is to assume that the distribution of these responses is the same as the underlying distribution of the positive responses. In effect, the decline to state responses are ignored and the distributions are based upon the positive data that is acquired.
F.3.1  Household Demographic Results Household Size Figure F1 presents the distribution of household size within the EPZ based on the responses to the demographic survey. The average household contains 2.43 people. The estimated household size from the 2020 Census data is 2.60 people (261,873 &#xf7; 100,714). The difference between the Census data and survey data is 6.54%, which exceeds the sampling error of 5.98%. This discrepancy was discussed with Duke Energy and it was decided that the Census estimate of 2.60 people per household should be used for this study. A sensitivity study is included in Appendix M to determine the impact to ETE on the estimated number of people per household.
Automobile Ownership The average number of automobiles available per household in the EPZ is 2.03. It should be noted that less than one percent of households do not have access to an automobile. The distribution of automobile ownership is presented in Figure F2. Figure F3 and Figure F4 present the automobile availability by household size. As expected, all households of 2 or more people have access to at least one vehicle.
Ridesharing Approximately 72 percent of the households surveyed responded that they would share a ride with a neighbor, relative, or friend if a car was not available to them when advised to evacuate in the event of an emergency, as shown in Figure F5.
Commuters Figure F6 presents the distribution of the number of commuters in each household. Commuters are defined as household members who travel to work or college on a daily basis. The data shows an average of 0.61 commuters in each household in the EPZ, and about 43 percent of households have at least one commuter.

Commuter Travel Modes Figure F7 presents the mode of travel that commuters use on a daily basis. The vast majority of commuters (87%) use their private automobiles to travel to work. The data shows an average of 1.09 commuters per vehicle, assuming 2 people per vehicle - on average - for carpools.
Impact of COVID19 on Commuters Figure F8 presents the distribution of the number of commuters in each household that were temporarily impacted by the COVID19 pandemic. Approximately 47 percent of households indicated someone in their household had a work and/or school commute that was temporarily impacted by the COVID19 pandemic.
Functional or Transportation Needs Figure F9 presents the distribution of the number of individuals with functional or transportation need. The data shows that approximately 3 percent of households have functional or transportation needs. Of those with functional or transportation needs, 38.5 percent require a bus, 15 percent require a medical bus/van, 38.5 percent require a wheelchair accessible van, and 8 percent require an ambulance.
F.3.2  Evacuation Response Several questions were asked to gauge the populations response to an emergency. These are now discussed:
How many of the vehicles would your household use during an evacuation? The response is shown in Figure F10. On average, evacuating households would use 1.31 vehicles.
Would your family await the return of other family members prior to evacuating the area?
Of the survey participants who responded, nearly 51 percent said they would await the return of other family members before evacuating and 49 percent indicated they would not await the return of other family members before evacuating or did not have family members (about 33 percent said they would evacuate independently and meet other household members, and about 16 percent indicated that they would evacuate independently because they are the only household member), as shown in Figure F11.
If you had a household pet, would you take your pet with you if you were asked to evacuate the area? Based on the responses to the survey, about 62 percent of households have a family animals or farm animals. Of the households with pets, about 24 percent of them indicated that they would take their pets with them to a shelter, nearly 75 percent indicated that they would take their pets somewhere else, and only about 1 percent would leave their pet at home. The response is shown in Figure F12. Of the households that would evacuate with their pets, 98 percent indicated that they have sufficient room in their vehicle to evacuate with their pets/animals. Of the households who have large farm animal(s), 80 percent of them have a covered area to protect livestock and stored food on hand to feed them for 72 hours.
What type of pet(s) and/or animal(s) do you have? Based on responses from the survey, nearly 92 percent of households have a household pet (dog, cat, bird, reptile, or fish), about 5 McGuire Nuclear Station                        F3                              KLD Engineering, P.C.

percent of households have service animals (horse or dog), and about 3 percent have livestock (horse, honeybees, or poultry). The response is shown in Figure F13.
Emergency officials advise you to take shelter at home in an emergency. Would you? This question is designed to elicit information regarding compliance with instructions to shelter in place. The results indicate that nearly 82 percent of households who are advised to shelter in place would do so; the remaining 18 percent would choose to evacuate the area. Note the baseline ETE study assumes 20 percent of households will not comply with the shelter advisory, as per Section 2.5.2 of NUREG/CR7002, Revision 1. Thus, the data obtained above is in good agreement with the federal guidance. A sensitivity study was conducted to estimate the impact of shadow evacuation noncompliance of shelter advisory on ETE - see Table M2 in Appendix M.
Emergency officials advise you to take shelter at home now in an emergency and possibly evacuate later while people in other areas are advised to evacuate now. Would you? This question is designed to elicit information specifically related to the possibility of a staged evacuation. That is, asking a population to shelter in place now and then to evacuate after a specified period of time. Results indicate that about 64 percent of households would follow instructions and delay the start of evacuation until so advised, while the other 36 percent would choose to begin evacuating immediately.
Emergency officials advise you to evacuate due to an emergency. Where would you evacuate to? This question is designed to elicit information regarding the destination of evacuees in case of an evacuation. Approximately 46 percent of households indicated that they would evacuate to a friend or relatives home, about 6 percent to a reception center, about 20 percent to a hotel, motel or campground, 9 percent to a second or seasonal home, and the remaining 19 percent responded other/dont know to this question. The response is shown in Figure F14.
F.3.3    Time Distribution Results The survey asked several questions about the amount of time it takes to perform certain pre evacuation activities. These activities involve actions taken by residents during the course of their daytoday lives. Thus, the answers fall within the realm of the responders experience.
The mobilization distributions provided below are the result of having applied the analysis described in Section 5.4.1 on the component activities of the mobilization.
As discussed in Section F.3.1 and shown in Figure F8, the COVID19 pandemic impacted about 47 percent of the commuters in the MNS EPZ. To minimize uncertainty in the commuting patterns obtained and resulting estimated trip generation times, data from the previous survey were compared to the results of this survey for the distributions involving commuters (time to prepare to leave work/college and time to travel home from work/college). For this reason, both the results of this survey, and the results of the previous survey for these questions are discussed herein. Due to the similar patterns between the two survey results and the close endpoints to the graphs (within 30 minutes), the results from this survey (labeled as 2021 in the graphs) are deemed acceptable for use in this study.

How long does it take the commuter to complete preparation for leaving work/college?
Figure F15 presents the cumulative distribution; in all cases, the activity is completed by about 75 minutes. Approximately 90 percent can leave within 40 minutes. In the previous study, the activity was completed by 90 minutes and 90 percent could leave within 35 minutes.
How long would it take the commuter to travel home ? Figure F16 presents the work to home travel time for the EPZ. About 91 percent (94.5% in the previous study) of commuters can arrive home within about 45 minutes of leaving work; all within 60 minutes (90 minutes in the previous study). In comparison, the 2021 distribution curve is shifted to the right resulting in a more conservative estimate for the time needed to travel home. In the previous study, the distribution curve has a long tail for the last 1% of the commuters which could be indicative of a larger variance in the data.
How long would it take the family to pack clothing, secure the house, and load the car? Figure F17 presents the time required to prepare for leaving on an evacuation trip. In many ways this activity mimics a familys preparation for a short holiday or weekend away from home. Hence, the responses represent the experience of the responder in performing similar activities. About 91 percent of households can be ready to leave home within 2 hours and 15 minutes; the remaining households require up to an additional 2 hours.
How much time, on average, would it take you to clear the snow/ice accumulation to move the car from the driveway or curb to begin the evacuation trip assuming the roads are passable? Figure F18 presents the time required to clear snow/ice and begin the evacuation trip. Snow/ice in this area is not common and residents are not used to clearing snow/ice from their driveways so responses to this question varies significantly.
Approximately 93 percent of households can have their car cleared and the driveway passable within 1 hour and 15 minutes; the remaining households would require up to an additional hour to begin their evacuation trip, as shown in Figure F18. As shown in the graph, just over 8% of households would not shovel and would just begin their evacuation trip.
F.3.4    Emergency Communications At your place of residence, how reliable is your cell phone signal? This question is designed to elicit information regarding the ability to be notified in case of an evacuation. Approximately 88 percent of households indicated that they have very reliable signal to receive texts and phone calls, 7 percent indicated that their signal is reliable for text messages only, and remaining 5 percent indicated that they either do not always receive cell communications at their residence or do not have cell service at their residence, as shown in Figure F19.
Emergency management officials in your state may send text messages, similar to AMBER Alerts, with emergency directions for the public during a radiological emergency at the McGuire Nuclear Station. How likely would you be to take action on these directions, if you received the message? This question is designed to elicit information regarding the likelihood of an individual to take action based on emergency management officials guidelines. About 84 percent of households indicated that they are highly likely to take action on these directions, McGuire Nuclear Station                          F5                              KLD Engineering, P.C.

about 13 percent indicated likely, 2 percent indicated neither likely nor unlikely (neutral), and about 1 percent indicated unlikely or highly unlikely to take action on emergency management officials directions, as shown in Figure F20.
Which of the following emergency communication methods do you think is most likely to alert you at your residence? This question is designed to elicit information regarding the most efficient way to alert residents within the EPZ. Approximately 77 percent of households indicated that a text message from emergency officials would be most likely to alert them at their residence, about 14 percent indicated that a siren sounding near their home would be the most likely method, about 6 percent indicated an alert broadcast on the TV/Radio, and 3 percent indicated that a phone call/text message from a family member, friend or neighbor would be the most likely way to alert them at their residence, as shown in Figure F21.

APPENDIX G Traffic Management Plan
 
G. TRAFFIC MANAGEMENT PLAN NUREG/CR7002, Rev. 1 indicates that the existing Traffic Control Points (TCPs) and Security Road Blocks (SRBs) identified by the offsite agencies should be used in the evacuation simulation modeling. The traffic control plans for the EPZ were provided by the OROs within the EPZ. These plans were reviewed, and the TCPs were modeled accordingly.
G.1 Manual Traffic Control TCPs and SRBs are forms of manual traffic control (MTC). As discussed in Section 9, MTC at intersections (which are controlled) are modeled as actuated signals. If an intersection has a pretimed signal, stop, or yield control, and the intersection is identified as a traffic control point (or SRB), the control type was changed to an actuated signal in the DYNEV II system, in accordance with Section 3.3 of NUREG/CR7002, Rev. 1. MTCs at existing actuated traffic signalized intersections were essentially left alone. Table K1 provides the control type and node number for those nodes which are controlled. If the existing control was changed due to the point being a TCP/SRB, the control type is indicated as TCP/SRB in Table K1. These MTC points, as shown in the TMP, are mapped as blue (TCP) dots and yellow (SRB) squares in Figure G1.
It is assumed that the TCPs and SRBs along Interstate 77 (I77), I485 and I85 will be established within 120 minutes of the advisory to evacuate (ATE) to discourage through travelers from using major through routes which traverse the EPZ.
G.2 Analysis of Key TCP /SRB Locations As discussed in Section 5.2 of NUREG/CR7002, Rev. 1, MTC at intersections could benefit from the ETE analysis. The MTC locations contained within the traffic management plans were analyzed to determine key locations where MTC would be most useful and can be readily implemented. In addition, modifications to the exiting TMP were analyzed to see if the ETE could be improved.
As previously mentioned, signalized intersections that were actuated based on field data collection were essentially left as actuated traffic signals in the model, with modifications to green time allocation as needed. Other controlled intersections (pretimed signals, stop signs and yield signs) were changed to actuated traffic signals to represent the MTC that would be implemented according to the traffic management plans. Table G1 shows a list of the controlled intersections that were identified as MTC points in the TMPs that were not previously actuated signals, including the type of control that currently exists at each location.
Preliminary simulations were generated and analyzed. Based on the congestion patterns, several TCPs and SRBs were modified to allow movements that were not permitted based on the TMP. Table G2 summarizes the modifications that were made to the TMP including the node, TCP/SRB number from the plan, the intersection description, location (Zone and County)

and a description of the modification that was made. These MTC locations are shown as red squares in Figure G1.
To determine the impact of the modifications listed in Table G2, a summer, midweek, midday, good weather scenario (Scenario 1) evacuation of the 2Mile, 5Mile and entire EPZ (Region R01, R02, R03) were simulated wherein these intersections were modeled with and without modification. The results are shown in Table G3. The ETE decreased by as much as 40 minutes and 1 hour at the 90th and 100th percentile, respectively. Although all of the modification contributed to less congestion and reduced ETE, some of the most impactful changes were at the interchanges with the various interstates. Permitting traffic to exit I77 (which very congested throughout the evacuation as seen in Figure 73 through 710) and utilize I85 and I 485 - essentially allowing the I77 off ramps to function as is - allows traffic to clear the EPZ more quickly.

APPENDIX J Representative Inputs to and Outputs from the DYNEV II System
 
J. REPRESENTATIVE INPUTS TO AND OUTPUTS FROM THE DYNEV II SYSTEM This appendix presents data input to and output from the DYNEV II System.
Table J1 provides source (vehicle loading) and destination information for several roadway segments (links) in the analysis network. There are a total of 995 source links (origins) in the model. The source links are shown as centroid points in Figure J1. On average, evacuees travel a straightline distance of 5.10 miles to exit the network.
Table J2 provides network-wide statistics (average travel time, average delay time1 average speed and number of vehicles) for an evacuation of the entire EPZ (Region R03) for each scenario. Rain Scenarios (Scenarios 2, 4, 7 and 10) and Ice Scenario (Scenarios 8 and 11) exhibit slower average speeds and longer average travel times and longer average delays compared to good weather scenarios. When comparing Scenario 13 (special event) and Scenario 9, the additional vehicles introduced by the special event lowers the average speeds and slightly increases the average travel time and average delay.
Table J3 provides statistics (average speed and travel time) for the major evacuation routes - I 485 WB, I485 EB, I77 NB and I77 SB - for an evacuation of the entire EPZ (Region R03) under Scenario 1 conditions. As discussed in Sections 7.3 and shown in Figures 73 through 710, there is significant congestion on the aforementioned routes throughout the evacuation; therefore, the travel times and speeds, shown in Table J3, are significantly lower than the freeflow speeds.
Table J4 provides the number of vehicles discharged and the cumulative percent of total vehicles discharged for each link exiting the analysis network, for an evacuation of the entire EPZ (Region R03) under Scenario 1 conditions. Refer to the figures in Appendix K for a map showing the geographic location of each link.
Figure J2 through Figure J15 plot the trip generation time versus the ETE for each of the 14 Scenarios considered. The distance between the trip generation and ETE curves is the travel time. Plots of trip generation versus ETE are indicative of the level of traffic congestion during evacuation. For low population density sites, the curves are close together, indicating short travel times and minimal traffic congestion. For higher population density sites, the curves are farther apart indicating longer travel times and the presence of traffic congestion.
As seen in Figure J2 through Figure J15, the curves are far apart as a result of the traffic congestion within in the EPZ, which clears at 5 hours and 40 minutes after the ATE for a summer, midweek, midday, good weather scenario, as discussed in detail in Section 7.3.
1 Computed as the difference of the average travel time and the average ideal travel time under free flow condition.

APPENDIX K Evacuation Roadway Network
 
K. EVACUATION ROADWAY NETWORK As discussed in Section 1.3, a linknode analysis network was constructed to model the roadway network within the study area. Figure K1 provides an overview of the linknode analysis network. The figure has been divided up into 107 more detailed figures (Figure K2 through Figure K108) which show each of the links and nodes in the network.
The analysis network was calibrated using the observations made during the field surveys conducted in December 2020.
Table K1 summarizes the number of nodes by the type of control (stop sign, yield sign, pre timed signal, actuated signal, traffic control point [TCP] and security road block [SRB],
uncontrolled).

APPENDIX M Evacuation Sensitivity Studies
 
M. EVACUATION SENSITIVITY STUDIES This appendix presents the results of a series of sensitivity analyses. These analyses are designed to identify the sensitivity of the ETE to changes in some base evacuation conditions.
M.1 Effect of Changes in Trip Generation Times A sensitivity study was performed to determine whether changes in the estimated trip generation time have an effect on the ETE for the entire Emergency Planning Zone (EPZ).
Specifically, if the tail of the mobilization distribution were truncated (i.e., if those who responded most slowly to the Advisory to Evacuate (ATE), could be persuaded to respond much more rapidly), or if the tail were elongated (i.e. spreading out the departure of evacuees to limit the demand during peak times), how would the ETE be affected? The case considered was Scenario 1, Region 3; a summer, midweek, midday, good weather evacuation of the entire EPZ.
Table M1 presents the results of this study.
If evacuees mobilize one hour quicker, the 90th percentile ETE is reduced by 10 minutes and the 100th percentile ETE is reduced by 30 minutes (a significant change), respectively. If evacuees mobilize one hour slower, the 90th and 100th percentile ETE are increased by 15 minutes and 1 hour (a significant change), respectively.
As discussed in Section 7.3, traffic congestion persists within the EPZ for about 5 hours and 30 minutes. If the time to mobilize is longer than 5 hours and 30 minutes, the 100th percentile ETE is dictated by trip generation time. For trip generation times less than 5 hours and 30 minutes, congestion dictates ETE. See Table M1.
M.2 Effect of Changes in the Number of People in the Shadow Region Who Relocate A sensitivity study was conducted to determine the effect on ETE of changes in the percentage of people who decide to relocate from the Shadow Region. The case considered was Scenario 1, Region 3; a summer, midweek, midday, good weather evacuation for the entire EPZ. The movement of people in the Shadow Region has the potential to impede vehicles evacuating from an Evacuation Region within the EPZ. Refer to Sections 3.2 and 7.1 for additional information on population within the Shadow Region.
Table M2 presents the evacuation time estimates for each of the cases considered. The results show that decreasing the shadow evacuation from 20% to 0% decreases the 90th percentile ETE by 5 minutes and the 100th percentile ETE remain unchanged. While tripling the shadow percentage from 20% to 60% increases the ETE by 30 minutes and 1 hour 5 minutes for the 90th and 100th percentiles, respectively - a significant change. A full evacuation of the Shadow Region increases the 90th and 100th percentile ETE by 1 hour 35 minutes and 3 hours, respectively. The significant increase in the ETE is due to the proximity of the EPZ boundary to the City of Charlotte, which is highly populated.
Note, the demographic survey results presented in Appendix F indicate that 18% of households would elect to evacuate if advised to shelter, which is in good agreement with the assumption of McGuire Nuclear Station                          M1                            KLD Engineering, P.C.

20% noncompliance suggested in NUREG/CR7002, Rev. 1. A sensitivity study was run using 18%
shadow and the ETE decreases the 90th percentile ETE by 5 minutes and the 100th percentile ETE remains the same.
The more people who voluntarily evacuate from beyond the EPZ boundary, the more the ETE is impacted. Care should be given on the evacuation shadow percentage during an emergency.
M.3 Effect of Changes in Permanent Resident Population A sensitivity study was conducted to determine the effect on ETE due to changes in the permanent resident population within the study area (EPZ plus Shadow Region). As population in the study area changes over time, the time required to evacuate the public may increase, decrease, or remain the same. Since the ETE is related to the demand to capacity ratio present within the study area, changes in population will cause the demand side of the equation to change and could impact ETE.
As per the NRCs response to the Emergency Planning Frequently Asked Question (EPFAQ) 2013001, the ETE population sensitivity study must be conducted to determine what percentage increase in permanent resident population causes an increase in the 90th percentile ETE of 25% or 30 minutes, whichever is less. The sensitivity study must use the scenario with the longest 90th percentile ETE (excluding the roadway impact scenario and the special event scenario if it is a one day per year special event).
The sensitivity study was conducted using the following planning assumptions:
: 1. The percent change in population within the study area was increased by up to 13%.
Changes in population were applied to permanent residents only (as per federal guidance), in both the EPZ and the Shadow Region.
: 2. The transportation infrastructure (as presented in Appendix K) remained fixed; the presence of future proposed roadway changes and/or highway capacity improvements were not considered.
: 3. The study was performed for the 2Mile Radius (R01), the 5Mile Radius (R02) and the entire EPZ (R03).
: 4. The scenario (excluding roadway impact and special event) which yielded the longest 90th percentile ETE values was selected as the case to be considered in this sensitivity study (Scenario 8 - Winter, Midweek, Midday with Ice).
Table M3 presents the results of the sensitivity study. Section IV of Appendix E to 10 CFR Part 50, and NUREG/CR7002, Rev. 1, Section 5.4, require licensees to provide an updated ETE analysis to the NRC when a population increase within the EPZ causes the longest 90th percentile ETE values (for the 2Mile Radius, 5Mile Radius or entire EPZ) to increase by 25% or 30 minutes, whichever is less. All base ETE values for the 2Mile Radius (R01), 5Mile Radius (R02), and for the entire (EPZ) are greater than 2 hours; 25% of these base ETE is always equal or greater than 30 minutes. Therefore, 30 minutes is the lesser and is the criterion for updating ETE.

Those percent population changes which result in the longest 90th percentile ETE change greater than or equal to 30 minutes are highlighted in red in Table M3 - a 13% or greater increase in the full EPZ permanent resident population (includes 20% of the Shadow permanent resident population). Duke Energy will have to estimate the full EPZ population on an annual basis. If the EPZ population increases by 13% or more, an updated ETE analysis will be needed.
M.4 Effect of Changes in Average Household Size As discussed in Appendix F, the average household size based on the 2020 Census data is 2.60 people. While based on the demographic survey, the average household contains 2.43 people.
The difference between the Census data and survey data is 6.54%, which exceeds the sampling error of 5.98%. Upon discussions with Duke Energy, it was decided that the Census estimate of 2.60 people per household would be used for this study. A sensitivity study was performed to determine how sensitive the ETE is to changes in the average household size. It should be noted that only resident and shadow vehicles were changed for this sensitivity study. The case considered was Scenario 1, Region 3; a summer, midweek, midday, with good weather evacuation of the 2Mile Radius, 5Mile Radius, and entire EPZ. Table M4 presents the results of this study.
Decreasing the average household size (increasing the total number evacuating vehicles) to 2.43 people per household also has little impact on ETE (increasing the 90th percentile ETE by 10 minutes at most). The difference in vehicles is only 4.5% of the total evacuating traffic (11,754 vehicles of 263,141 vehicles for this scenario - see Table 64). As such, this incremental increase in vehicles has little to no impact on the ETE. The 100th percentile ETE remains dictated by trip generation time and as a result is not impacted by the change in people per household.
Regardless of the household size utilized in the study (Census versus survey), the results would likely be about the same.
M.5 Enhancements in Evacuation Time This appendix documents sensitivity studies on critical variables that could potentially impact ETE.
Possible improvements to ETE are further discussed below:
Reducing or prolonging the trip generation time an hour impacts the 90th percentile ETE by 10 to 15 minutes and the 100th percentile ETE by 30 minutes to 1 hour, since trip generation within the EPZ dictates ETE (Section M.1). Thus, public outreach encouraging evacuees to mobilize more quickly can decrease ETE.
Increasing the percent shadow evacuation (especially over 40%) has a significant impact on ETE (Section M.2). As such, public outreach could be considered to inform those people within the EPZ (and potentially beyond the EPZ) that if they are not advised to evacuate, they should not.
Population growth results in more evacuating vehicles which could significantly increase ETE (Section M.3). Public outreach to inform people within the EPZ to evacuate as a family in a single vehicle would reduce the number of evacuating vehicles and could reduce ETE or offset the impact of population growth.
