APPENDIX DDetailed Description of Study Procedure D. DETAILED DESCRIPTION OF STUDY PROCEDUREThis appendix describes the activities that were performed to compute Evacuation TimeEstimates. The individual steps of this effort are represented as a flow diagram in Figure D-1.Each numbered step in the description that follows corresponds to the numbered element inthe flow diagram.Step 1The first activity was to obtain EPZ boundary information and create a GIS base map. The basemap extends beyond the Shadow Region which extends approximately 15 miles (radially) fromthe power plant location. The base map incorporates the local roadway topology, a suitabletopographic background and the EPZ boundary.Step 22010 Census block information was obtained in GIS format. This information was used toestimate the resident population within the EPZ and Shadow Region and to define the spatialdistribution and demographic characteristics of the population within the study area. Transient,employment, and special facility data were obtained from Exelon, county emergencymanagement agencies, and phone calls to individual facilities.Step 3Next, a physical survey of the roadway system in the study area was conducted to determinethe geometric properties of the highway sections, the channelization of lanes on each sectionof roadway, whether there are any turn restrictions or special treatment of traffic atintersections, the type and functioning of traffic control devices, gathering signal timings forpre-timed traffic signals, and to make the necessary observations needed to estimate realisticvalues of roadway capacity.Step 4The results of a telephone survey of households within the EPZ were obtained from Exelon toidentify household dynamics, trip generation characteristics, and evacuation-relateddemographic information of the EPZ population. This information was used to determineimportant study factors including the average number of evacuating vehicles used by eachhousehold, and the time required to perform pre-evacuation mobilization activities.Step 5A computerized representation of the physical roadway system, called a link-node analysisnetwork, was developed using the UNITES software (see Section 1.3) developed by KLD. Oncethe geometry of the network was completed, the network was calibrated using the informationgathered during the road survey (Step 3). Estimates of highway capacity for each link and otherlink-specific characteristics were introduced to the network description. Traffic signal timingswere input accordingly. The link-node analysis network was imported into a GIS map. 2010Census data were overlaid in the map, and origin centroids where trips would be generatedduring the evacuation process were assigned to appropriate links.LaSalle County Generating Station D-1 KLD Engineering, P.C.Evacuation Time Estimate Rev. 0 Step 6The EPZ is subdivided into 13 Sub-areas. Based on wind direction and speed, Regions (groupingsof Sub-areas) that may be advised to evacuate, were developed.The need for evacuation can occur over a range of time-of-day, day-of-week, seasonal andweather-related conditions. Scenarios were developed to capture the variation in evacuationdemand, highway capacity and mobilization time, for different time of day, day of the week,time of year, and weather conditions.Step 7The input stream for the DYNEV II model, which integrates the dynamic traffic assignment anddistribution model, DTRAD, with the evacuation simulation model, was created for a prototypeevacuation case -the evacuation of the entire EPZ for a representative scenario.Step 8After creating this input stream, the DYNEV II System was executed on the prototypeevacuation case to compute evacuating traffic routing patterns consistent with the appropriateNRC guidelines. DYNEV II contains an extensive suite of data diagnostics which check thecompleteness and consistency of the input data specified. The analyst reviews all warning anderror messages produced by the model and then corrects the database to create an inputstream that properly executes to completion.The model assigns destinations to all origin centroids consistent with a (general) radialevacuation of the EPZ and Shadow Region. The analyst may optionally supplement and/orreplace these model-assigned destinations, based on professional judgment, after studying thetopology of the analysis highway network. The model produces link and network-widemeasures of effectiveness as well as estimates of evacuation time.Step 9The results generated by the prototype evacuation case are critically examined. Theexamination includes observing the animated graphics (using the EVAN software whichoperates on data produced by DYNEV II) and reviewing the statistics output by the model. Thisis a labor-intensive activity, requiring the direct participation of skilled engineers who possessthe necessary practical experience to interpret the results and to determine the causes of anyproblems reflected in the results.Essentially, the approach is to identify those bottlenecks in the network that representlocations where congested conditions are pronounced and to identify the cause of thiscongestion. This cause can take many forms, either as excess demand due to high rates of tripgeneration, improper routing, a shortfall of capacity, or as a quantitative flaw in the way thephysical system was represented in the input stream. This examination leads to one of twoconclusions:" The results are satisfactory; or* The input stream must be modified accordingly.LaSalle County Generating Station D-2 KLD Engineering, P.C.Evacuation Time EstimateRev. 0 This decision requires, of course, the application of the user's judgment and experience basedupon the results obtained in previous applications of the model and a comparison of the resultsof the latest prototype evacuation case iteration with the previous ones. If the results aresatisfactory in the opinion of the user, then the process continues with Step 13. Otherwise,proceed to Step 11.Step 10There are many "treatments" available to the user in resolving apparent problems. Thesetreatments range from decisions to reroute the traffic by assigning additional evacuationdestinations for one or more sources, imposing turn restrictions where they can producesignificant improvements in capacity, changing the control treatment at critical intersections soas to provide improved service for one or more movements, or in prescribing specifictreatments for channelizing the flow so as to expedite the movement of traffic along majorroadway systems. Such "treatments" take the form of modifications to the original prototypeevacuation case input stream. All treatments are designed to improve the representation ofevacuation behavior.Step 11As noted above, the changes to the input stream must be implemented to reflect themodifications undertaken in Step 10. At the completion of this activity, the process returns toStep 9 where the DYNEV II System is again executed.Step 12Evacuation of transit-dependent evacuees and special facilities are included in the evacuationanalysis. Fixed routing for transit buses and for school buses, ambulances, and other transitvehicles are introduced into the final prototype evacuation case data set. DYNEV II generatesroute-specific speeds over time for use in the estimation of evacuation times for the transitdependent and special facility population groups.Step 13The 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 userinterface. For each specific case, the population to be evacuated, the trip generationdistributions, the highway capacity and speeds, and other factors are adjusted to produce acustomized case-specific data set.Step 14All evacuation cases are executed using the DYNEV II System to compute ETE. Once results areavailable, quality control procedures are used to assure the results are consistent, dynamicrouting is reasonable, and traffic congestion/bottlenecks are addressed properly.LaSalle County Generating Station D-3 KLD Engineering, P.C.Evacuation Time Estimate Rev. 0 Step 15Once vehicular evacuation results are accepted, average travel speeds for transit and specialfacility routes are used to compute evacuation time estimates for transit-dependent permanentresidents, schools, hospitals, and other special facilities.Step 16The simulation results are analyzed, tabulated and graphed. The results were thendocumented, as required by NUREG/CR-7002.Step 17Following the completion of documentation activities, the ETE criteria checklist (see AppendixN) was completed.

TELEPHONE SURVEYF.1 IntroductionThe development of evacuation time estimates for the LAS EPZ requires the identification oftravel patterns, car ownership and household size of the population within the EPZ.Demographic information can be obtained from Census data. The use of this data has severallimitations when applied to emergency planning. First, the Census data do not encompass therange of information needed to identify the time required for preliminary activities(mobilization) that must be undertaken prior to evacuating the area. Secondly, Census data donot contain attitudinal responses needed from the population of the EPZ and consequently maynot accurately represent the anticipated behavioral characteristics of the evacuating populace.These concerns are addressed by conducting a telephone survey of a representative sample ofthe EPZ population. The survey is designed to elicit information from the public concerningfamily demographics and estimates of response times to well defined events. The design of thesurvey includes a limited number of questions of the form "What would you do if ...?" and otherquestions regarding activities with which the respondent is familiar ("How long does it take youto ...?")Attachment A presents the final survey instrument used in this study. A sample size of 376completed survey forms yields results with a sampling error of +/-5% at the 95% confidencelevel. The sample must be drawn from the EPZ population.The preliminary determination of whether a household was located inside the EPZ was basedon "land-line" telephone listings with street addresses. Telephone surveys were thenconducted using those numbers, selected in random order, until the target level of surveys wascompleted, or the entire calling list was exhausted. Rejections or households outside the EPZwere discarded. Numbers with "no answer" were re-cycled for up to ten attempts in differenttime windows.F.2 Survey ResultsThe results of the survey fall into two categories. First, the household demographics of the areacan be identified. Demographic information includes such factors as household size, automobileownership, and automobile availability. The distributions of the time to perform certain pre-evacuation activities are the second category of survey results. These data are processed todevelop the trip generation distributions used in the evacuation modeling effort, as discussed inSection 5.A review of the survey instrument reveals that several questions have a "don't know" (DK) or"refused" entry for a response. It is accepted practice in conducting surveys of this type toaccept the answers of a respondent who offers a DK response for a few questions or whorefuses to answer a few questions. To address the issue of occasional DK/refused responsesfrom a large sample, the practice is to assume that the distribution of these responses is thesame as the underlying distribution of the positive responses. In effect, the DK/refusedresponses are ignored and the distributions are based upon the positive data that is acquired.LaSalle County Generating Station F-1 KLD Engineering, P.C.Evacuation Time Estimate Rev. 0 F.2.1 Household Demographic ResultsHousehold SizeFigure F-i presents the distribution of household size within the EPZ.

These activities involve actions taken by residents during the course oftheir day-to-day lives. Thus, the answers fall within the realm of the responder's experience.The mobilization distributions provided below are the result of having applied the analysisdescribed in Section 5.4.1 on the component activities of the mobilization."How long do you think it would take [the primary commuter] to get prepared and actuallyleave work?" Figure F-6 presents the cumulative distribution; in all cases, the activity iscompleted within 75 minutes.

Please assume that you are advised to plan to be away from your home for 3 days."Figure F-8 presents the time required to prepare for leaving on an evacuation trip. In manyways this activity mimics a family's preparation for a short holiday or weekend away fromhome. Hence, the responses represent the experience of the responder in performing similaractivities. About 76 percent of households can be ready to leave home within 40 minutes; theremaining households require up to an additional 80 minutes.Preparation Time with Everyone Home100%003W4-0W-CL80%60%40%20%0%0 30 60 90Preparation Time (min)120Figure F-8. Time to Prepare Home for EvacuationThe survey conducted in support of this study did not ask residents how long it would takethem to remove snow from their driveway if there were snow on the ground when anevacuation was ordered. As discussed in Section 5.3, the response to the snow removalquestion in a survey conducted in 2012 in support of ETE development for the Duane ArnoldEnergy Center (DAEC) is adapted for this study. DAEC is located in Iowa, approximately 170miles west-northwest of LAS. It is assumed that snowfall and snow removal times arecomparable in both EPZs.F-8 KLD Engineering, P.C.LaSalle County Generating StationEvacuation Time EstimateF-8KLD Engineering, P.C.Rev. 0 "How long would it take you to clear 6 to 8 inches of snow from your driveway?" Duringadverse, snowy weather conditions, an additional activity must be performed before residentscan depart on the evacuation trip. Although snow scenarios assume that the roads andhighways have been plowed and are passable (albeit at lower speeds and capacities), it may benecessary to clear a private driveway prior to leaving the home so that the vehicle can accessthe street. Figure F-9 presents the time distribution for removing 6 to 8 inches of snow from adriveway. The time distribution for clearing the driveway has a long tail; about 96 percent ofdriveways are passable within 60 minutes. The last driveway is cleared two hours after thestart of this activity. Note that those respondents (46%) who answered that they would nottake time to clear their driveway were assumed to be ready immediately at the start of thisactivity. Essentially they would drive through the snow on the driveway to access the roadwayand begin their evacuation trip.Time to Remove Snow from Driveway0i00100%80%60%40%20%0%0 15 30 45 60Time (min)75 90 105 120Figure F-9.

TRAFFIC MANAGEMENT PLANNUREG/CR-7002 indicates that the existing TCPs and ACPs identified by the offsite agenciesshould be used in the evacuation simulation modeling. The traffic and access control plans forthe EPZ were provided by the Illinois Emergency Management Agency.These plans were reviewed and the TCPs and ACPs were modeled accordingly.G.1 Traffic Control PointsAs discussed in Section 9, traffic control points at intersections (which are controlled) aremodeled as actuated signals. If an intersection has a pre-timed signal, stop, or yield control, andthe intersection is identified as a traffic control point, the control type was changed to anactuated signal in the DYNEV II system. Table K-2 provides the control type and node numberfor those nodes which are controlled. If the existing control was changed due to the point beinga TCP, the control type is indicated as "TCP -Actuated" or "TCP -Uncontrolled" in Table K-2.The TCPs and ACPs within the study area are mapped in Figure G-1.G.2 Access Control PointsIt is assumed that ACPs will be established within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of the advisory to evacuate todiscourage through travelers from using major through routes which traverse the EPZ. Asdiscussed in Section 3.6, external traffic was considered on the major route which traverses thestudy area 80 -in this study. The generation of the external trips ceases at 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> after theadvisory to evacuate in the simulation due to the ACPs.As shown in Figure G-1, the TCPs and ACPs identified in the county and state emergency plansare concentrated along major evacuation routes and on roadways giving access to the EPZ.These TCPs and ACPs would be manned during evacuation by traffic guides who would directevacuees in the proper direction away from the plant and facilitate the flow of traffic throughthe intersections.Detailed descriptions of each of the TCPs and ACPs and the actions to be taken by traffic guidesat these intersections are provided in the county and state plans. These actions were modeledexplicitly in the DYNEV II system. For additional information, refer to the county and state plans.As discussed in Section 9, this study did not identify any additional intersections as TCPs orACPs. The existing county and state traffic management plans are comprehensive in terms ofdiscouraging traffic from entering the EPZ.LaSalle County Generating Station G-1 KLD Engineering, P.C.Evacuation Time Estimate Rev. 0

EVACUATION REGIONSThis appendix presents the evacuation percentages for each Evacuation Region (Table H-i) andmaps of all Evacuation Regions (Figure H-1 through Figure H-22). The percentages presented inTable H-1 are based on the methodology discussed in assumption 5 of Section 2.2 and shown inFigure 2-1.Note the baseline ETE study assumes 20 percent of households will not comply with the shelteradvisory, as per Section 2.5.2 of NUREG/CR-7002.The City of Marseilles, Illinois is split between 2 Sub-areas. The eastern half of the city is in Sub-area 10, while the western half is in Sub-area 11. Based on discussions with Exelon and theoffsite agencies, the city would always evacuate as a whole when wind is blowing toward thecity (Sub-area 10, 11, or both included in keyhole). Thus, keyholes wherein Sub-area 10 isincluded, but not Sub-area 11 would still result in the City of Marseilles evacuating entirely. Forexample Region R08 is an evacuation of the 5-mile radius and downwind to the EPZ boundarywith wind toward the northeast or east-northeast. When the wind is toward the northeast,Marseilles is in the keyhole (when using the 3-sector approach described in Section 6) and theentire city evacuates. When the wind is toward the east-northeast, the city is not within thekeyhole, but Sub-area 10 (which includes Marseilles) is. Thus, the entire city evacuates.Similarly, keyholes wherein Sub-area 11 is included, but not Sub-area 10 would also result in theentire city evacuating. For example, Region R17, with the wind blowing toward the west-northwest, Marseilles is not within the keyhole, but Sub-area 11 (which includes Marseilles) is.Thus, the entire city evacuates. The evacuation of the City of Marseilles is shown graphically inFigures H-6 through H-8 and H-17 through H-19.LaSalle County Generating StationEvacuation Time EstimateH-1KLD Engineering, P.C.Rev. 0 Table H-1.
