- 1. INTRODUCTION 1.1 General Evacuation time studies analyze the manner in which the population within the Plume Exposure Pathway Emergency Planning Zone (EPZ) surrounding a nuclear power plant site would evacuate during a radiological emergency. Evacuation time studies provide licensees and State and local governments site-specific information helpful to protective action decision-making. The studies estimate, for officials who would make protective action decisions, the time necessary to evacuate the EPZ, and identify instances in which. unusual evacuation constraints exist.
Evacuation time estimate requirements were developed in the aftermath of the Three Mile Island accident. In a letter dated November 29, 1979, the U.S. Nuclear Regulatory Commission - (NRC) issued a request for information regarding estimates of evacuation times for various areas around nuclear power plants. In November of 1980, the NRC and the Federal Emergency Management Agency (FEMA) published a revised version of NUREG-0654 entitled Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants (NUREG-0654, Rev. 1, November 1980) (Reference 1). NUREG-0654, Rev. 1 requires that each nuclear power plant licensee's offsite emergency plan contain time estimates for evacuation within the Plume Exposure EPZ, and Appendix 4 of NUREG-0654, Rev. 1 provides detailed guidance on what must be included in an evacuation time estimate study. In response to NUREG-0654, Rev. 1, Illinois Power Company (IPC) has retained HMM Associates (HMM) of Concord, Massachusetts to develop the evacuation time estimates for the Clinton Power Station EPZ. This report will be provided to State and County officials for their use in the event of an emergency. Il78/0074h 1-1
The evacuation time estimates have been developed using updated, existing population data and the NETVAC computer simulation model. The NETVAC program was developed specifically to provide evacuation time estimates and related information for use in emergency planning. Evacuation times have been estimated for various areas, times and weather conditions, as suggested by Appendix 4 of NUREG-0554, Rev. 1. These evacuation times represent the times required for completing the following actions:
- 1. public notification;
- 2. preparation and mobilization; and
- 3. actual movement out of the EPZ (i.e., on-road travel time, including delays associated with vehicle queueing). __
l.2 Site Location and Plume Exposure Pathway Emergency Planning Zone (EPZ) The Clinton Power Station is located in the Township of Harp, within DeWitt County, Illinois. The plant site is located approximately 7 miles northeast of Clinten City, 12 miles southwest of Farmer City, 22 miles south of Bloomington and 20 miles north of Decatur. A site vicinity map for the Clinton Power Station is included in Figure 1.1. The Plume Exposure Pathway Emergency Planning Zone (EPZ) is the geographic area surrounding a nuclear power plant within which the NRC requires advance planning for evacuation or other short-term protective actions in the event of a radiological l ll78/0074h 1-2

emergency. NRC regulations define the Plume Exposure Pathway EPZ as follows: Generally, the Plume Exposure Pathway EPZ for nuclear power plants shall consist of an area about 10 miles (16 kilometers) in radius... The exact size and configuration of the EPZ surrounding a particular nuclear power reactor shall be determined in relation to local emergency response needs and capabilities as they are affected by such conditions as demography, topography, land characteristics, access routes and jurisdictional boundaries.* The Clinton Power Station EPZ encompasses land areas in four counties: DeWitt, McLean, Platt and Macon. There are 15 townships entirely or partially within this area. They are as follows: Clintonia, Creek, DeWitt, Harp, Nixon, Rutledge, _ Santa Anna, Texas, Wapella and Wilson in DeWitt County; Friends Creek in Macon County; Downs and Empire in McLean County; and Blue Ridge and Goose Creek in Platt County. The Clinton Power Station EPZ boundary was defined following a detailed review of the demography, topography, land characteristics, access routes and jurisdictional boundaries in the area surrounding the power station. This review resulted in a determination that the primary basis for EPZ boundary definition should be political l jurisdictions or man-made features (e.g., highways, railroads, canals, etc.) or strong topographical features (e.g., streams, mountains, rivers, etc.) as well as Clinton Lake across the middle of the area, which could consistently serve as boundary segments. i
- 10CFR, Section 50.47(c)(2). The NRC provides further guidance for defining the Plume Exposure Pathway TPZ in NUREG-0654, Rev. 1.
l l 1178/0074h 1-4 k
Supportive evidence for the use of political jurisdictions to form the EPZ boundary is given by the strong bond between a given population and its political subdivision / city, town or township of residence. Furthermore, political subdivision boundaries in the area of the Clinton Power Station have been very stable and are expected to maintain that stability. For this reason, political subdivision boundaries are highly appropriate when considering the establishment of a stable, long-term EPZ boundary. Another reason for the predominant use of political subdivisions in defining the EPZ boundary is that many of the designated local response agencies (particularly fire and police departments) are structured on the basis of local political subdivisions and are established to serve these subdivisions. Designation of the EPZ along these boundaries simplifies many aspects of off-site emergency response planning and preparation. _ In cases where the local political jurisdictional boundaries were not reasonably near the 10-mile radius of the Clinton Power Station, attempts were made to use man-made, or topographical features as a boundary basis. In such cases, highways were the preferred choice as the basis for the EPZ definition. Figure 1.2 illustrates the boundaries of the Clinton Power Station EPZ. Beginning on the east, the EPZ ucundary follows County Highway 4 (Deland/ Farmer City Blacktop) in DeWitt County and County Highway 5 in Platt County south from Salt Creek to State Highway 10. It then follows State Highway 10 west to 425E* in Goose Creek Township, and then travels south along 425E to 2200N. The EPZ boundary then turns west along 2200N until reaching 400E and then continues south on 400E to the Goose Creek / Willow Branch Township boundary. It subsequently travels westward along this township line for
- 425E identifies a rural route on the County section line grid system.

approximately four miles to the junction with State Highway 48. The EPZ boundary then turns southward along State Highway 48 for one mile before traveling westward for about seven miles along Macon County Highway 38 to the Friends Creek /Marca Township line. It then follows this township line northward for about one mile to the DeWitt County boundary (i.e., County Line Road). At this point, the EPZ boundary follows the DeWitt County boundary toward the west for approximately four miles before turning north along U.S. Highway 51. It then continues northward along U.S. Highway 51 for approximately 1.5 miles until reaching DeWitt County Highway 11 (Kenney Road). From this junction, the boundary travels westward along County Highway 11 to the western border of Texas Township. It then follows the entire length of the western borders of Texas, Clintonia and Wapella Townships northward for about 14 miles until reaching the McLean County boundary. The EPZ boundary then travels eastward along the McLean County boundary for
~
nearly six miles before turning northward for two miles along the Randolph/ Downs Township boundary in McLean County. The EPZ boundary then heads eastward along State Highway 136 for approximately ten miles until its junction with Interstate Route 74. It then follows Interstate Route 74 in McLean County toward the southeast to approximately the junction of 2500E in Santa Anna Township, following this line in a southerly direction to Salt Creek and meanders eastward along Salt Creek to County Highway 5. NUREG-0654, Rev. 1, further recommends that the EPZ be subdivided into Evacuation Analysis Areas, as follows: Radius Area 0 about 2 miles four 90 sectors about 5 miles four 90 0 sectors about 10 miles (EPZ) four 90 0 sectors about 10 miles (EPZ) entire EPZ l ll78/0074h 1-7
For the purpose of this study, the EPZ has been subdivided U into Analysis Areas based on the sixteen 22-1/2 sectors which are used for evacuation planning in the State of Illinois. Evacuation of the area out to two miles of the Clinton Power Station would be accomplished on a 3600 basis and would be included in the evacuation of any portion of the EPZ. In addition, the geographical areas defined by that portion of DeWitt, McLean, Platt and Macon Counties within the EPZ have been included as Analysis Areas. Evacuation time estimates have been developed for all Analysis Areas under various seasonal and weather conditions pursuant to NUREG-0654, Rev. 1 guidance. For evacuation and emergency response planning purposes, these Analysis Areas have been further divided into 30 Sub-Areas. The relationship between the evacuation Analysis Areas and Sub-Areas is summarized in Table 1.1. The Clinton Power Station EPZ Sub-Area boundaries have _ been identified and established based on demography, topography, land characteristics, access routes and jurisdictional boundaries.* A descripticn of the Sub-Areas within each County follows: DeWITT COUNTY SUB-AREA 1 Includes the area within Harp, Creek and DeWitt Townships, in DeWitt County, bounded by the shore of Lake Clinton on the South and West, and on the North and Northeast by the Harp Township Line to Highway 54 and East to County Highway 14. SUB-AREA 2 Includes that portion of Harp Township, in DeWitt - County, Nortia of Highway 54 and West of County Highway 21. SUB-AREA 3 Includes that portion of DeWitt Township in DeWitt County North of Highway 54 excluding DeWitt Village.
- The State of Illinois in conjunction with County officials, established these boundaries for use in developing County Radiological Emergency Response Plans (RERPs) for the Clinton Power Station EPZ.

- 2. METHODOLOGY AND ASSUMPTIONS 2.1 Sources of Data In order to estimate evacuation times, a number of data sources were reviewed to develop the appropriate input required for the computer simulation model used for the analysis. These data sources included the following:
o Population estimates were developed from (1) data presented in the 1980 Census of Population and Housing (Reference 2), (2) a review of County Highway maps and U.S. Geological Survey topographic maps (Reference 3), and (3) a telephone survey conducted by HMM Associates during May and June 1984 (References 12 through 38) and updated during September 1985. o The peak estimated employment level at the Clinton Power Station. o Roadway geometric and operational data were collected by HMM Associates field crews during May 1984. County highway maps obtained from the Illinois Department of Transportation were also reviewed. o Roadway and intersection approach capacities were calculated by the NETVAC computer model using algorithms developed from the 1965 Highway Capacity l Manual (Reference 4), and relationships identified in the 1980 Interim Materials on Highway Capacity ! (Reference 5).* I , j
- The 1980 Interim Materials on Highway Capacity provides a compilation of current roadway and intersection capacity l analysis procedures to supplement those contained in the l 1965 Highway Capacity Manual.
l ll78/0075h 2-1 L
o Preparation and mobilization times have been developed for each population sector. These times were based upon discussions with IPC and
. State / County emergency services officials, on a review of site-specific characteristics of the Clinton Power Station EPZ, and upon a review of available empirical data. Officials from the Clinton/DeWitt County and Illinois ESDAs have participated in the compilation and selection of these preparation and mobilization times.
i o Vehicle occupancy rates for the various population sectors were based upon (1) discussions with County emergency services officials and representatives of the various special facilities within the Plume Exposure EPZ; (2) permanent and seasonal resident household size;and (3) assumptions about occupancy - of recreational and hotel / motel facilities within the EPZ. + 2.2 General Assumptions Several qualifying assumptions were made during the course of this study, as outlined below: o The evacuation time estimates represent the time required to evacuate the Clinton Power Station EPZ and Analysis Areas within it, and include the time
- required for initial notification.
o It is assumed that subsequent to initial notification, all persons within the EPZ will evacuate. Evacu& tion of the EPZ will be considered complete after all evacuating vehicles are outside of the EPZ. 1178/0075h 2-2
o The general public will be evacuated through Reception Centers to Host Areas outside of the potential hazard area. Children from all schools
.w ithin the area evacuated will be transported directly to these Host Areas.
o The permanent population sector will evacuate from their places of residence. All households having more than one vehicle will only use one automobile. This is consistent with empirical data (Reference 32) which indicates that family members, where possible, prefer to evacuate as a unit. o It is assumed that existing lane utilization patterns will prevail during the course of the evacuation. However, it is also assumed that appropriate County and State Police personnel will - restrict unauthorized access into the EPZ. o Transportation for non-auto-owning households will be furnished through rides with neighbors, friends and relatives, or through coordinated efforts by State and County emergency services officials. o Adverse weather refers to what is defined as a moderate snowstorm which would reduce roadway capacity and travel speeds by 30 percent during the winter, and a light-to-moderate rainstorm which would reduce roadway capacity and travel speeds by 20 percent during the summer (refer to Section 5.2 and Reference 7). 1178/0075h 2-3
2.3 Summary of Methodology The NETVAC computer simulation model was used to perform the evacuation time, estimates. This is a computer program developed by HMM Associates in collaboration with Professor Yosef Sheffi of the Massachusetts Institute of Technology's Center for Transportation Studies. The model was developed specifically to provide evacuation time estimates and related ; information for use in emergency planning. The NETVAC program has the following characteristics which led to its selection for use in this study: o The model accounts for the detailed di.stribution of vehicle demand. o The model considers fundamental physical and opbrational characteristics of the evacuation road - network. o The model accounts for the dynamic characteristics of evacuation traffic flows. o The model provides thorough documentation of
- - results.
O The model provides a means for examining a complex problem in a structured manner. O The model can readily address fair weather versus adverse weather conditions. o The model can readily address evacuation scenarics occurring at different times of day. 1178/0075h 2-4
o The model can readily address changes in population which would be likely to occur within the EPZ at different times of the week and different times of
. year.
o NETVAC has been used for evacuation studies at 18 nuclear power plant sites. Its validity as a prediction tool has been established in previous NRC proceedings. The NETVAC program is a flexible, fixed-step, macro traffic simulation model which uses traffic flow relationships to calculate and record traffic densities, speeds, flows, queues and other relevant information throughout the evacuation process. The model employs a sophisticated list processing method to represent the evacuation as a series of links (road segments) and nodes (intersections). Traffic is first entered at designated entry nodes in the highway network. At every simulation interval, the model processes vehicles from the links entering an intersection to the links emanating from it. The NETVAC model includes a dynamic route selection feature whereby drivers' choice of outbound links, at every intersection, is based on two criteris:
- 1. The degree to which an outbound link leads away from the plant, or the direction of specific evacuation routings where such plans exist.
! 2. The traffic conditions on the outbound links (i.e., travel speeds and presence of vehicle queueing cr l congestion). { l The roadway and intersection approach capacities f calculated by the NETVAC program are based upon data and traffic flow relationships presented in the Highway Capacity Manual and the Interim Materials on Highway Capacity . Due to ll78/0075h 2-5
the dynamic route assignment mechanism, approach capacities are updated at each simulation interval to account for potential changing turning movements. The intersection control options which can be specified with the NETVAC model include intersections with traffic signals and priority control intersections (i.e., stop or yield signs). The core of the NETVAC program is the simulation subroutine. This part of the program executes a given number of procedures at user-specified simulation intervals. The simulator includes two major logical units: the link pass and the node pass. The link pass calculates the number of vehicles that would reach the. upstream node or join the queue there in a given simulation interval. The node pass calculates how many vehicles should be processed from each of the links entering a particular intersection (inbound links) to each of the outbound links. Figure 2.1 schematically represents the interrelation-ship between the link pass and node pass simulation procedures. - A more detailed description of the NETVAC program is described in Section 5.4. 2.4 Conditions Modeled Pursuant to NUREG-0654, Rev. 1 guidance, evacuation time estimates have been prepared for several. temporal, seasonal and weather conditions. Estimates have been prepared for winter day fair and adverse weather conditions, a winter night fair weather condition, a summer weekday fair weather condition, and summer weekend fair and adverse weather conditions. Fair weather refers to conditions where roadways are clear and dry, and visibility is not impaired. Adverse weather is defined as a snowstorm during winter periods where roadway capacities are reduced by 30 percent and a sudden rainstorm j during summer periods where capacities are reduced by 20 percent (Reference 7). l I I i 1178/0075h 2-6 l

- 3. POPULATION AND VEHICLE DEMAND ESTIMATION The development of vehicle demand estimates for the Clinton Power Station EPZ consisted of two steps. The first step was the determination of the number and distribution of the population to be evacuated. The second step was the determination of the appropriate number of vehicles required to evacuate each of the population categories. Federal guidance (NUREG-0654, Rev. 1) indicates that three population categories should be considered: permanent residents, transients, and persons in special facilities (such as school and medical facilities, nursing homes, etc.).
The methodology used to develop the total population and vehicle demand estimates within the Clinton Power Station EPZ incorporates intrinsic double-counting. For example, it is reasonable to assume that a portion of the identified employees within the area and visitors to recreational areas are also - permanent residents within the EPZ. In addition, school children, treated as an independent special facility category, are also included in the permanent population estimates. Including this double counting of population, however, is done intentionally to implicitly simulate traffic friction on the network due to travel home prior to the actual evacuation. In short, this technique double counts population, but more accurately reflects anticipated vehicle activity on the evacuation network (e.g., where a child evacuates directly from school the rest of his family will still depart from the residence, but with one less passenger in the car). In Sections 3.1, 3.2, 3.3 and 3.4 population totals are 0 presentJd.for 22-1/2 sectors, at one-mile increments for ".e Clinton Power Station EPZ. The population totals by Analysis Area are summarized in Section 3.5. l l r 3.1 Permanent Residents Permanent residents are defined as those persons having year-round residences within the Clinton Power Station EPZ. t ll78/0076h 3-1 l
Permanent population and housing unit estimates for the area were based upon data presented by the 1980 Census of Population and Housing and a review of County Highway and U.S. Geological Survey topographic maps. These data were used to develop population totals and distributions within the EPZ. Figure 3.1 presents the 1980 permanent resident population by sector. The permanent resident population and vehicle demand data is presented in Appendix 1. 3.1.1 Auto-Owning Permanent Population It was assumed that one vehicle would evacuate from each permanent resident household. This assumption is consistent with empirical data (Reference 8) indicating the tendency of evacuees to evacuate, where possible, as a family unit. The 1980 Federal Census data included information on the average number of persons per household for the various townships - within the EPZ. These relationships were applied to the permanent population totals, to obtain estimates of the vehicle demand associated with the permanent resident population. Vehicle occupancy rates range from 2.4 to 3.0 persons per vehicle. 3.1.2 Non-Auto-Owning Permanent Population The 1980 U.S. Census of Population and Housing was used to identify the number of permanent residences without access to a vehicle. This information is presented at the end of Appendix 1. During an evacuation, transportation for all non-auto-owning households will be furnished through rides with neighbors or thrcugh coordinated efforts by State and County emergency services officials. The exact number of vehicles which would be required to evacuate this population category would vary based upon several factors, including the type and , ll78/0076h 3-2

number of transportation resources available at the time of the evacuation. For the purpose of this evacuation time estimate study, the same vehicle occupancy rate (i.e., one vehicle per household) developed for the auto-owning permanent residents was used to develop vehicle demand estimates for the non-auto-owning permanent residents. This assumption was used since it provides the most realistic representation of evacuation traffic which would be generated from the non-auto-owning households, accounting for vehicles within the network following internal routes to collect non-auto-owning passengers. 3.2 Seasonal Residents The seasonal population segment includes those residents who reside in the area on a temporary basis, particularly during the summer period. Seasonal residences are typically not insulated'and are suitable for occupancy for only a portion - of the year. 1980 seasonal household data for the area were obtained from the U.S. Census of Housing. Seasonal resident population and vehicle demand estimates were developed from average household size and vehicle occupancy surveys conducted for this population segment by HMM Associates at other sites (Reference 9). Figure 3.2 presents the seasonal resident population, by sector, for the Clinton Power Station EPZ, The seasonal population within each township was distributed based on a review of U.S.G.S. topographic maps and the location of areas likely to have seasonal land uses. The seasonal population data along with the corresponding vehicle demand estimates for this population segment are presented in Appendix 2. 3.3 Transient Population The transient population segment includes persons in the work force, motels / hotels, and recreational areas. Major workplace employee population estimates were verified through a 1178/0076h 3-4

telephone survey conducted by HMM Associates in June 1984. A listing of all major industrial employers identified within the EPZ and a map identifying the location of these employers are presented in Appendices 3 and 5, respectively. Data for the major hotels / motels and recreational areas within the EPZ were also verified through a telephone survey conducted by HMM during May and June 1984. A listing of major hotels / motels and recreational areas within the EPZ is also presented in Appendix 3. Figure 3.3 presents the total transient population within the EPZ in rose format. For purposes of estimating total vehicles associated with the transient population segment, an auto occupancy factor of 1.0 employee per vehicle was used for all employees except for the Clinton Power Station. Based upon discussions with IPC officials, an average plant vehicle occupancy factor of 2.2 persons per vehicle for each analysis scenario was used. Hotel / motel and campground occupancy factors used were 1.0 - vehicle per hotel / motel room and 1.0 vehicle per camp site. Vehicle occupancy rates for other recreational areas were based on discussions with facility officials. These occupancy rates were developed for an estimate of peak vehicle demand, where recreational areas and hotels / motels are fully occupied. The resultant vehicle demand would be conservative for periods where occupancy of these transient population categories were lower than peak levels. The vehicle demand associated with the transient population segment is presented in Appendix 3 while their locations are presented in Appendix 5. Some double-counting of total vehicle demand may be inherent in these estimates since a portion of the identified employees and visitors to the recreational areas may also be permanent residents of the Clinton Power Station EPZ. However, this more accurately simulates traffic conditions on the network due to employees or other transients traveling home prior to the actual evacuation. 1178/0076h 3-6 i i

3.4 Special Facilities The special facility population segment includes persons in school, hospital, nursing home or jail facilities who may require special transportation considerations during an evacuation. The population (verified by HMM through a telephone survey conducted in June 1984 and updated in September 1985) and vehicle l demand associated with these facilities is summarized in Appendix
- 4. The vehicle demand for medical and jail facilities was calculated based on 40 ambulatory persons per bus and 2 non-ambulatory persons per ambulance. For schools, the vehicle demand was calculated based on 60 students per bus and one staff member per vehicle (Reference 10). Figure 3.4 presents the special facility population totals, by sector, for the Clinton Power Station EPZ. Appendix 5 includes maps locating these special facilities within the EPZ.
3.5 Evacuation Analysis Area Population Totals Table 3.1 summarizes the population totals, by category, for each of the previously identified Analysis Areas. The Sub-Areas included within each Analysis Area are also identified. These totals represent peak population levels for permanent residents, seasonal' residents, transients and persons in special i facilities. A description of the population within each of the 30 Sub-Area divisions follows (refer to Section 1.2 for a detailed description and map showing the Sub-Area boundaries): Sub-Area 1 Sub-Area 1 include portions of Harp, Creek and DeWitt Townships bordered largely by Clinton Lake. There are 142 permanent residents in Sub-Area 1 and no seasonal residents. The cork force population includes the employees at the plant. In addition, a peak population of 9421 at various Clinton Lake recreational areas exists during summer weekend periods. 1178/0076h 3-8

- 4. THE EVACUATION ROADWAY NETWORK 4.1 Network Definition In order to estimate evacuation clear-times, an evaluation of the roadway network likely to be used by departing vehicles was undertaken in May 1984. In defining the evacuation roadway network, HMM relied heavily on several sources of information, including:
- 1) County, local and USGS maps of the EPZ area;
- 2) Discussions with County law enforcement and transportation personnel, as well as with State and County ESDA officials; and
- 3) A comprehensive field survey of the Clinton Power -
Station EPZ. Based on this data, an evacuation network was identified to be used for evacuation simulation modeling. This network was reviewed with County ESDA officials. The traffic network elements considered in the evacuation modeling consist of the major streets and intersections within the EPZ. The major streets include roadways of the following classifications: o Arterial Streets. As characterized by continuity of travel; connecting business, population, or major recreation areas, and traffic controls and geometric designs which enhance traffic flow and safety. Examples of main arterials are U.S. Highway 51 and l State Highways 10, 54 and 48. t o Collector Streets are links between residential areas served by local roads and arterial streets. , These are characterized by lower design standards and frequent stops at minor intersections. Examples 1178/0084h 4-1
of collector streets include Birkbeck Road (DeWitt County Highway 21) in Harp Township, as well as Long Road (DeWitt County Highway 15) and White Pigeon
. Road (DeWitt County Highway 5) in Nixon and Creek Townships, respectively.
The smaller local residential roadways are not specifically evaluated as part of the model simulation but are taken into account as part of the vehicle loading process. The primary evacuation routings are indicated on Figure 4.1. 4.2 Evacuation Route Descriptions The primary Reception Center locations to be used by . evacuees will be located in the cities of Bloomington to the north, Champaign to the east, Decatur to the south, and Lincoln to the west of the Clinton Power Station EPZ. The primary evacuation routings were developed so as to permit a general radial travel pattern away from the Clinton Power Statior., toward the Reception Centers. Descriptions of the major evacuation routes for each of the previously identified evacuation Sub-Areas are outlined below: Sub-Area 1 Local routes to: o State Highway 54 to Interstate 74 East toward Champaign; o State Highway 54 West toward Lincoln; o State Highway 10 East toward Champaign; o State Highway 10 West toward Lincoln; o DeWitt County Highway 16 North toward Bloomington; and o DeWitt County Highway 5 South toward Decatur.

Using both field studies and available maps, the geometric descriptions for each component of the network were compiled. Field data included the number l of lanes, lane widths, shoulder widths, distances to obstructions, grade, cruise speeds, traffic controls and other ll78/0084h 4-8 \ l
data necessary to calculate the traffic capacity of each link in the system. Sample field data recording forms are presented in Figure 4.2. Link lengths were measured from available maps. Roadway geometric and operational data for each intersection in the network was also collected.
- The data from these efforts were coded and keypunched for input to the NETVAC model. The model, in turn, provides a listing of the evacuation roadway network and its characteristics. The network listing, presented in Appendix 6, describes the geometric characteristics of each link in the network. The listing also describes the possible turning movements from each node and the traffic capacity of each link in the network (vehicles per hour that can be accommodated on each link during an evacuation). The listing of geometric characteristics and capacities is provided by the preprocessor for the NETVAC computer model prior to the actual evacuation simulation calculations.
For the purpose of identification and for subsequently calculating evacuation times, the network has been coded into a system of 104 directional links and 70 nodes. The evacuation network which was used for the computer simulation, is shown in Figure 4.3. The figure shows the locations and number codes for each node in the network. l l l l

Time estimates have been prepared for (1) Winter Day, Fair and Adverse Weather Conditions, (2) a Winter Night, Fair Weather Condition, (3) a Summer Weekday, Fair Weather Condition, and (4) Summer Weekend, Fair and Adverse Weather Conditions. 5.2 Adverse Weather Conditions For the purpose of this study, adverse weather refers to what is defined as: (1) a moderate snowstorm (i.e., snowfall greater than or equal to 1.0 in.) during winter periods where roadway capacities and travel speeds are reduced by 30 percent of normal weather capacity, and (2) a rainstorm (precipitation greater than or equal to 0.1 in.) during summer periods where normal weather capacities and travel speeds are reduced by 20 percent. These adverse conditions were selected because they represent the most frequently occurring adverse weather scenarios within the Clinton Power Station area during a given season of the year, as indicated in Section 2.3 of the CPS FSAR (Reference 11). Moderate snowstorms have been shown to occur approximately two percent of the time (i.e., relative to the total number of days in a year), while the adverse rain condition has been indicated to occur about 30 percent of the time. Evacuation time estimates were not provided for adverse weather conditions such as flooding and tornadoes during the summer, and severe snowstorms (i.e., snowfall greater than six inches over a 7500 square mile area) during the winter. These extreme weather conditions were not included as analysis cases because such events occur, on the average, less than once per year at the Clinton Power Station site. Specifically, severe winter storms have been shown to occur approximately every 1.4 years in DeWitt County. Tornado probability at the Clinton Power Station is .0031, which reflects an occurrence every 325 years (Reference 11). Since this study addresses the most common adverse conditions, the ll78/0085h 5-2
effects on evacuation times of extreme weather conditions were not evaluated. Moreover, during severe weather, the possibility of sheltering, rather than evacuating, is likely to be considered. During severe snowstorms, for example, evacuation could not begin until roads are cleared. The adverse weather conditions modeled in this study are intended to represent the upper (more conservative) limit where roads are passable but not in good condition. 5.3 Initial Notification The EPZ surrounding the Clinton Power Station has a notification system consistent with NUREG-0654, Rev. 1 guidelines. This system will be used by County and' State officials to alert the population to turn on their radios and television sets. Pursuant to NUREG-0654, Rev. 1 guidance, notification messages will commence on the designated _. television and EBS radio stations virtually immediately. Within 15 minutes essentially all the population within the EPZ should have been given an informational or instructional message. If evacuation is deemed necessary, the timing of the order to evacuate and notification measures will be controlled by the State and County emergency preparedness officials. They may choose to alert and mobilize an emergency response work force to control and expedite evacuation prior to the evacuation order. 5.4 Evacuation Preparation Times and Departure Distributions It is assumed that no vehicles will begin to evacuate l during the 15-minute initial notification period. It is also ! assumed that there will be a minimum preparation / mobilization time of 15 minutes for all population segments. Accordingly, in the model simulations, no vehicles begin to evacuate until l l 30 minutes following the initial notification. Network loading Il78/0085h 5-3 l
d 4 distribution assumptions for the permanent population, transient population and special facilities are described below, and summarized in Figure 5.1. Permanent Population Permanent residents with access to automobiles will take varying amounts of time to begin evacuating. Some persons will leave as quickly as possible; most will take some time to prepare, pack valuables and clothes and then depart; and some will take added time to secure property before departing. In addition, actual preparation and departure times may vary according to the perceived severity of a paIticular evacuation order. Based upon a review of the site-specific characteristics of.the'Clinton Power Station EPZ, a review of available empirical data, and discussions with County and State emergency - services officials, it was assumed that there would be a two-hour period over which the permanent residents would begin to evacuate. That is, permanent resident households would begin to evacuate between 30 and 150 minutes after the initial notification. It was further assumed that 15 percent of the permanent population would begin to evacuate between 30 and 60 minutes following initial notification, 40 percent would begin to evacuate between 60 and 90 minutes, an additional 40 percent would begin to evacuate between 90 and 120 minutes, and the remaining 5 percent would begin to evacuate between 120 and 150 minutes of the initial notification. Transient Population It was assumed that the work force would receive initial notification promptly. It was also assumed that the majority of the work force would be released expeditiously (i.e., within 30 minutes subsequent to notification). Discussions with local emergency services officials indicate that a maximum of 30 1178/0085h 5-4

minutes may be needed for the work force to begin to evacuate. This preparation time would include the time required for securing businesses, shutting down active operations, etc. Therefore, it was assumed that the work force preparation / mobilization times would be uniformly distributed over a 30-minute period. Discussions with local emergency services officials also indicate that this distribution would be reasonable for the other transient population categories within the Clinton EPZ, including hotels / motels and recreational areas. Therefore, it was assumed that all of the transient population vehicles would begin to evacuate between 30 and 60 minutes following initial notification. That is, vehicles associated with the transient population would begin to evacuate during a 30-minute period, beginning 30 minutes subsequent to initial notification. Special Facilities _ It was assumed that special facilities (i.e., schools, the hospital, nursing home and jail) within the EPZ would also receive initial notification promptly. Based upon discussions with local emergency services officials, vehicle departure times ~ reflecting notification / preparation / mobilization distributions, were developed. Pursuant to discussions with ESDA officials, it was assumed that all public schools would be evacuated via bus to designated Host Centers. For school facilities, it was assumed that up to a 90-minute period would be required to load students onto buses, subsequent to the 15-minute notification and a 15-minute minimum preparation period. Accordingly, school buses were loaded onto the evacuation network from the period between 30 and 120 minutes following the initial emergency alert. Evacuation of the hospital, nursing home and the DeWitt County jail would require additional time associated with preparation and transport of vehicles to the respective 1178/0085h 5-6
facilities. Based upon discussions with County and State emergency services personnel, it was assumed that these facilities would begin to evacuate between 60 and 150 minutes following the 15-minute notification period. Therefore, vehicles serving these special facilities would begin to evacuate between 75 and 165 minutes following the initial notification. 5.5 Evacuation Simulation Evacuations were simulated using the population and vehicle demand distribution data, evacuation network data, and evacuation preparation and departure time distribution assumptions discussed in previous sections. The actual
~
simulated evacuations were performed using the NETVAC computer program. The following describes the general structure of the model and three of its major features: the dynamic route - selection, the priority treatment of flow at intersections not having traffic signals, and the roadway and intersection capacity calculations. _ General St"ucture The NETVAC program is organized in four basic units (procedures): the main program, the data procedure, the preprocessor, and the simulator. This section briefly explains the functions of each of these units. The main program controls the entire execution. It starts by calling on the data procedure, which reads in the data and the execution instructions, then calls in the preprocessor which performs some preliminary capacity calculations. Next, the main program controls the simulatien itself and the reporting of the network conditions at specified intervals. This program also controls l the' rest of the reports and the length of the simulation by terminating the program once the network is empty. Il78/0085h 5-7 I
The data procedure reads in the network, the parameters and the options to be used in the simulation. The data procedure performs a set of checks on the network to ensure connectivity and validity. It also performs a set of checks on the input data to identify coding errors. The data procedure also produces a set of warnings if unlikely (but possible) situations are encountered. The preprocessor procedure converts the physical description of each link into measures of capacity, speed and density. For each specified type of link, the preprocessor computes two types of capacity: o Section capacity - which is the capacity along the link regardless of downstream intersection restrictions; and - 0 Approach capacity - which is the capacity of the _ link to handle vehicles approaching the downstream intersection. Section capacities are associated with highway sections whereas the traffic flow through intersections is controlled by the approach capacity. The NETVAC program computes both capacities since they serve different purposes. The section capacity serves as an upper bound on the flow that can move along a link, restricting the number of vehicles that will reach the intersection during a simulation interval and the number of vehicles that can be loaded onto a link from the intersection. The approach capacity, on the other hand, limits the number of cars that can actually move through the intersection. Vehicles that reach the intersection but cannot mova through it are assigned to a queue, or back-up. The NETVAC simulator includes two separate procedures, the link pass and the node pass. The link pass handles the flow on the links while the node pass handles the transfer of flow from link to link. 1178/0085h 5-8
Dynamic Route Selection The NETVAC program does not use a pre-specified set of turning movements at each intersection; instead, the turning movements are determined at each simulation interval as a function of the changing traf fic conditions and directionality of the links. Drivers approaching an intersection are assumed to make a choice of outbound (away from the intersection) links based on how fast this outbound link can get them to safety. This, in turn, is a function of the direction of the outbound links (away from the nuclear plant or hazard area) and the traffic conditions on the outbound links. The route selection procedure used in the NETV AC program reflects the two above-mentioned choice criteria through a user-supplied " preference f actor" which is specified for each link and the speeds on each of the outbound links. In order to f acilitate the explanation of the route choice mechanism, let - PF j denote the preference factor for the j-th outbound link at some intersection. In other words, the relative 'a priori' preference of link j is PF) 1/ PF k k where the sum goes over all the links (k's) emanating out of the node under consideration (including j). The choice probability, or the , share of drivers choosing an outbound link j out of a given intersection at (simulated) time t , P j( t), is determined as a function of the preference factors and the speeds on all the outbound links as: PF x U j(t) 3 Pj (t) = 2 PF k x ' Uk( U) where Uj (t) is the speed on link j at time t. It should be L noted that driver behavior during an evacuation is assumed to be myopic in that only information regarding the immediate outbound links at each intersection is assumed to influence route choice decisions. l l l 666/4623C 5-9
The Priority Treatment Even under evacuation conditions, it can be expected that traf fic approaching an intersection without traf fic signals
~
from certain links would have the right of way over incoming traf fic f rom lower priority approaches. Since it is not clear that such priority would correspond to the existing intersection controls, the input to NETVAC includes a user-specified link priority parameter. This is a binary parameter indicating a primary or secondary priority of a link. The volume of vehicles being processed (at every intersection and at each simulation interval) and transferred from inbound to outbound links is subject to several constraints which determine the ef fective capacity of the intersection. During the simulation, traf fic coming in f rom all primary priority links is assigned to the intersection first, subject only to the intersection capacity constraints. _. Lower priority traffic, on the other hand, is rest ricted by both the capacity of the intersection and the effect of the higher priority traffic. The capacity of the secondary priority approaches is a function of the gap acceptance behavior of the minor approach drivers and the headway distribution in the primary approaches' flow. In order to model the capacity of secondary priority approaches, a capacity allocation problem procedure is utilized. The secondary priority approaches emit traf fic only under one of the following conditions: fi rst , if there is residual intersection capacity f rom the primary priority traf fic, flow can be emitted into the intersection f rom the secondary. priority road subject to the residual capacity constraint. Second, if the residual capacity is zero, NETVAC provides some small capacity for the lower priority approaches to allow for " sneak-in" ef fects. l 666/4623C 5-10
Capacity Calculations The capacity of a transportation f acility is the maximum flow that can travel along the facility. The NETVAC program determines capacity 'in two stages : fi rs t , the preprocessor assigns a section capacity and an approach capacity to each link in the network. Second, approach capacities are updated continuously, throughout the simulation as changing turning e.ovements af fect the maximum volume of traf fic processed along each link into its downstream intersection. The capacity calculations are based on the Highway Research Board's Highway Capacity Manual. Following this re fe rence , the section capacity is calculated in the prepro-cessor for links with and without physical separation 'oetween opposing directions while the approach capacity is calculated as a function of the physical conditions (width, parking, turning pockets, etc.), environmental conditions (area type, _ peak hour and load factors), traf fic characteristics (traf fic mix and percentage of turning movements), and approach type. The capacity of the i-th approach coming into an intersection at simulation interval t, C 1(t) is given by : Cg ( t) = C f x AL(t) x AR( t) where C 1 is the standard capacity of link i calculated by the preprocessor and AL(t) and AR(t) are the correction f actors for left and right turning movements, respectively. These correction factors are a function of the percent of turning traffic, the approach width, and parking allowance, and do not apply when the turning traf fic is using special turning lanes or turning pockets. 666/ 4623C 5-11

- 6. ANALYSIS OF EVACUATION TIMES i 6.1 Evacuation Time Estimate Summary I
Evacuation time estimates for each of the evacuation l Analysis Areas are presented in Table 6.1. These estimates represent the total time for vehicles within the various evacuation Analysis Areas to clear the EPZ, and include the time required for notification, preparation and mobilization activities. The total number of people to be evacuated for each of the evacuation Analysis Areas was presented, by population category, in Section 3. A summary of the simulated evacuation times for each of the Analysis Areas follows: Analysis Area 1: 0-2 Miles (Sub-Area 1) A large portion of the vehicles evacuating this Analysis Area during weekday periods are from the Clinton Power Station site. The Clinton Lake recreational area represents the origin of a majority of evacuating vehicles during a summer weekend. The estimated time to evacuate the population within this area is 155 minutes (2 hours, 35 minutes) for all time and weather conditions. The most significant partion of the total evacuation time for any time and weather condition is the maximum preparation and mobilization time associated with the permanent population. The only vehicle queueing which occurs under this case is along the Clinton Power Station main access road at the intersection of State Highway 54. This queueing occurs primarily during weekday conditions, when the plant is at its peak daytime employment level. The reduced roadway capacity associated with the adverse weather conditions does not significantly affect the evacuation times since sufficient capacity is available along area roadways to handle the peak vehicle demands associated with the 0-2 mile area, i 1178/0087h 6-1

Analysis Areas 2 thru 17: All 0-5 Mile Cases (Sub-Areas 1 thru 8, 10, 11, 12) The estimated evacuation times for each Analysis Area within five miles of Clinton Power Station are primarily influenced by the time associated with preparation and mobilization activities. The maximum estimated fair weather evacuation time for any of the 0-5 mile Analysis Areas is 165 minutes (2 hours, 45 minutes). This is the time that would be required to evacuate the 0-5 mile Analysis Areas in the northeast, east, and southeast sectors of the EPZ, under either winter weekday or summer weekday fair weather conditions. All other fair weather evacuations of the 0-5 mile Area are completed within 155 minutes (2 hours, 35 minutes) of initial
~
notification. The maximum estimated adverse weather evacuation time is 170 minutes (2 hours, 50 minutes), and generally occurs for - Analysis Areas within the eastern half of the EPZ under winter snow conditions. This time is only ten minutes longer than the corresponding fair weather times for these Analysis Areas. The summer weekend, adverse weather evacuation time estimate for each 0-5 mile Analysis Area is 155 minutes (2 hours, 35 minutes). This result is the same as that indicated for each Analysis Area under summer weekend, fair weather conditions. The reduced roadway capacity associated with snow has only a slight effect on evacuation times for areas within five miles of the plant. Capacity reductions due to rain have negligible impacts on these evacuation times. l The only locations where significant vehicle queueing occurs are along the Clinton Power Station main access road, as well as along Randolph Street and Old Clinton Raad. Vehicle queues occur on these roadways under both fair and adverse weather conditions, but are most pronounced during periods of rain and snow. I , 1178/0087h 6-3 l
I j l l Analysis Areas 18 thru 33: All 0-10 Mile Cases (Sub-Areas 1 thru 30) 1 The evacuation times for areas out to ten miles of the plant vary more widely than'those indicated for the 0-5 mile areas. In general, estimated evacuation times for 0-10 mile Analysis Areas in the eastern half of the EPZ are all within ten $1nutes of estimates for corresponding 0-5 mile Analysis Areas. These times are primarily governed by the preparation and mobilization time of the permanent residents. Capacity restrictions along Old:Clinton Road and Randolph Street are a limiting factor during periods of combined heavy demand from plant work force and DeWitt residents. Evacuation of 0-10 mile Analysis Areas in the western half of the EPZ frequently includes the City of Clinton. The City contains a majority of the permanent resident population within the'EPZ. It is estimated that fair weather evacuation of areas _. which include the City of Clinton would take up to 195 minutes (3 hours, 15 minutes). Vehicle queueing and associated delays would occur throughout the evacuation period, particularly along Van Buren, Center and Madison Streets in the City of Clinton. Capacity restrictions along these roadways are the primary influence on the evacuation time for these areas. Fair weather evacuation times for remaining Analysis Areas toward the west are mostly attributable to the preparation and mobilization time of the permanent resident population. Time estimates for these areas do not exceed 165 minuts (2 hours, 45
..inutes) for any of the fair weather scenarios.
Adverse weather evacuation times for Analysis Areas including the City of Clinton are also significantly longer than estimated tir.ies for other 0-10 mile Analysis Areas under rain and snow conditions. Winter weekday, adverse weather time estimates for areas including the City of Clinton can take up to 240 minutes (4 hours). The maximum estimateo evacuation time for these areas under summer weekend, adverse weather conditions is 235 minutes (3 hours, 55 minutes). The reduced ll78/0087h 6-4
roadway capacities and travel speeds associated with these weather conditions significantly affect the total evacuation time. Vehicle queueing and delay occurs at the same locations indicated for fair weather conditions, but is more pronounced during periods of snow and rain. The estimated adverse weather evacuation times for remaining areas in the western half of the EPZ are, in general, within 10 minutes of corresponding fair weather times and range between 160 minutes (2 hours, 40 minutes) and 170 minutes (2 hours, 50 minutes). The most significant portion of these evacuation times is the maximum preparation and mobilization time associated with the permanent resident population. Analysis Area 34: DeWitt County DeWitt County has the largest total population of the four counties included within the EPZ. The longest fair weather evacuation time of 195 minutes (3 hours, 15 minutes) occurs during a summer weekend. This time is governed by the large transient recreational population as well as by resultant vehicle demand and capacjty limitations along Van Buren, Center and Madison Streets in the City of Clinton. The next longest fair weather evacuation time of 190 minutes (3 hours, 10 minutes) occurs during a summer weekday. This time is governed primarily by factors similar to those influencing the weekend evacuation. The estimated fair weather evacuation times for winter weekday and winter weeknight conditions are 185 minutes (3 hours, 5 minutes) and 180 minutes (3 hours), respectively. The estimated winter weekday time is five minutes longer because the population associated with this scenario is greater than the evacuating population under winter weeknight conditions. Vehicle queueing for these ' weekday and weeknight cases is also present at locations along Van Buren, Center and Madison Streets. Thus, capacity limitations along these roadways are the determining factor of winter weekday and weeknight evacuation times. 1178/0087h 6-5
l l The winter weekday and summer weekend, adverse weather f evacuation times are 240 minutes (4 hours) and 235 minutes (3 hours, 55 minutes), respectively. Both times are higher than j their corresponding fair weather cases due to capacity restrictions caused by snow and rain. The estimated time for the winter weekday, adverse weather scenario is slightly longer due to greater roadway capacity restrictions resulting from snow conditions. Analysis Areas 35, 36 and 37: McLean County, Platt County and Macon County Only a small portion of the total land area as well as total population of the EPZ is within these counties. Evacuating vehicles are associated almost exclusively with the permanent resident population. Evacuation of each county on a separate basis would take approximately 155 minutes (2 hours, - 35 minutes) for all time and weather conditions as indicated in Table 6.1. The estimated evacuation times for McLean, Platt and Macon Counties are limited by the maximum preparation and mobilization time associated with the permanent residents. Analysis Area 38: Full EPZ Analysis Area 14 includes the evacuation of the entire Clinton Power Station EPZ. For winter weekday, fair weather conditions, the estimated evacuation time is 185 minutes (3 hours, 5 minutes). This time is the same as that estimated for j DeWitt County. This evacuation time is influenced primarily by the capacity limitations of several sections of Van Buren l Street within the City of Clinton. Vehicle queueing along the entire length of this street occurs throughout the evacuation procedure. The capacity limitations and resultant queues are primarily the result of delays occurring at the signalized intersection of Van Buren Street and U.S. Highway 51. Other locations where consistent queueing is indicated are as follows: ! 1178/0087h 6-6
r o State Highway 10 at Van Buren Street; 4 o State Highway 54 at Van Buren Street; f a Madison Street at Van Buren Street; o State Highway 54 at Main Street; 1 o Randolph Street at State Highway 54; o Walnut Street at Webster Street; and o Center Street at Woodlawn Avenue and U.S. Highway 51. i All of these locations are in the City of Clinton except for the Randolph Street location which is in the Village of DeWitt. A summary of the locations where vehicle queueing occurs _
- during the course of an evacuation for winter weekday, fair - weather conditions is presented in Appendix 7. Also, Figure I
6.1 presents.a summary of cumulative vehicle departures from th'e Clinton EPZ, as a function of time, for the winter weekday condition. A review of this figure indicates a steady rate of departures of vehicles leaving the EPZ during the time period between 1 and 3 hours following the evacuation order. - The estimated evacuation time for winter weeknight, fair weather. conditions is 180 minutes (3 hours). Vehicle queueing that occurs during the course of this evacuation is present, 4 although in a less pronounced form, at the same locations as for winter daytime conditions, except for the intersection of 4 [ f Randolph Street and State Highway 54. Significant queueing at this-location occurs only during weekday evacuations when there is a heavy vehicle demand associated with a combination of the Clinton Power Station work force and permanent residents from I the Village of DeWitt. The nighttime reduction in plant work L force reduces vehicle demand along Randolph Street and i i' ll78/0087h 6-7 ( t
alleviates queueing in the area. Figure 6.2 summarizes the total' departures from the EPZ, as a function of time, for winter weeknight, fair weather conditions. The estimated evacuation time for summer weekend, fair weather conditions is 195 minutes (3 hours, 15 minutes). This time is the longest. estimated fair weather evacuation time. It is the same as the estimated summer weekend evacuation time for DeWitt County. The summer weekend population is larger than-that for any other analysis time period. Significant vehicle queueing under summer weekend, fair weather conditions is indicated at the same locations as for winter weekday, fair weather conditions. Intermittent vehicle queueing occurs during the outset of the evacuation at access roads to the Clinton Lake and Weldon Springs State Park recreational areas. A summary of locations where vehicle queueing occurs during'the course of an evacuation for the summer weekend, fair
-weather scenario is presented in Appendix 7. Also, Figure 6.3 -
presents a summary of cumulative vehicle departures from the Clinton EPZ, as a function of time, for the summer weekend, fair weather condition. A comparison of Figure 6.3 with Figure 6.1 shows vehicles departing at a slightly faster rate during the summer weekend than during the winter. weekday. The reason for this difference in departure rates is that the large summer weekend recreational population has a relativel.y short preparation and mobilization time. Under summer weekday, fair weather conditions, it is estimated that it will take 190 minutes (3 hours, 10 minutes) to evacuate the EPZ. This summer weekday evacuation case has t he second largest population of all full EPZ analysis cases. i Figure 6.4 presents a summary of cumulative vehicle departures from the Clinton Power Station EPZ, as a function of time, for the summer weekday, fair weather conditions. A comparison of Figure 6.4 with Figure 6.3 shows a similar departure rate for both summer weekday and weekend conditions. Il78/0087h 6-8
, I l l Evacuation time estimates for the winter day and summer weekend, adverse weather conditions are 240 minutes (4 hours) and 235 minutes (3 hours, 55 minutes), respectively. The key locations where congestion is most prevalent are the same as those identified for the fair weather scenarios, although weather-related reductions in vehicle capacity and travel speed would make the extent of vehicle queueing more significant for the adverse weather cases, especially the winter snow condition. Figures 6.5 and 6.6 present the total vehicle departures from the EPZ, as a function of time, for the winter weekday and summer weekend, adverse weather conditions. The general vehicle departure characteristics for both adverse weather conditions are similar to corresponding fair weather departures. Impacts of Clinton By-Pass and Route 51 Widening For analysis purposes, an evacuation time estimate was also developed for both a winter daytime and summer weekend, fair weather evacuation of the Clinton EPZ with the Clinton By-Pass in full operation and U.S. Route 51 widened to four lanes, two in each direction. It was expected that these improvements to the evacuation roadway network might reduce vehicle congestion within the City of Clinton. Evacuation of the EPZ under winter weekday, fair weather conditions with the By-Pass in operation is estimated to take 185 minutes (3 hours, 5 minutes). Meanwhile, it is estimated that an evacuation of the EPZ under summer weekend, fair weather conditions would take 195 minutes (3 hours, 15 minutes). These times are the same as for the corresponding full EPZ evacuation without the Clinton By-Pass and with U.S. Route 51 providing one travel lane in each direction. This result indicates that inter-city (i.e., non-local) traffic, which is the type of traffic that would be expected to most utilize the By-Pass, is not a major determining factor in these estimated evacuation times.

congestion and delays indicated within the City of Clinton are caused by intra-city (i.e., local) traffic. Therefore, it appears that implementation of the Clinton By-Pass and widening of U.S. Route 51 would not promote faster radial travel out of the EPZ during an evacuation. Impacts of Apple and Park Festival An evacuation time estimate has also been developed for an evacuation of the full EPZ during the Apple and Park Festival. This special event is held annually in the City of Clinton during the last. full weekend of September. This supplemental time estimate was developed using the summer weekend population and vehicle demand level as a base condition for evaluation ' purposes. Vehicles associated with the Apple and Pork Festival
! were subsequently added to the base case level to simulate probable conditions during the festival.
The estimated total peak population in the area at any given time during the festival is 50,000 people. An average vehicle occupancy of 3.0 persons per vehicle was used to develop the vehicle demand levels for the population associated with this event.* Therefore, there would.be up to 16,500 more vehicles evacuating the EPZ during this event, compared to average peak summer conditions (i.e., a summer weekend without the festival). The notification / preparation / mobilization time distribution for the transient recreational population was applied to people attending the Apple and Park Festival. Therefore, it was assumed that all of the vehicles associated with the festival population would begin to evacuate between 30 and 60 minutes following initial notification.
- Population and vehicle occupancy estimates provided by Ms.
j Marilyn Strain, Coordinator, Clinton/DeWitt County ESDA. l Il78/0087h 6-16
For summer weekend, fair weather conditions with the Apple and Park Festival, the estimated evacuation time is 305 minutes (5 hours, 5 minutes). This time is about 110 minutes (1 hour, 50 minutes) longer than that estimated for summer weekend, fair weather conditions without the festival. In both cases, the evacuation time is influenced primarily by the capacity limitations of Van Buren Street within the City of Clinton. The increased vehicle demand associated with the Apple and Park Festival results in significantly increased vehicle flows along Van Buren Street as well as all other major roadways exiting the City of Clinton. The capacity limitations of Van Buren Street and the increased vehicle demand for its use as an evacuation route during the festival combine to increase the estimated clear time for the EPZ. During an evacuation with ' this special event, vehicle queueing occurs along the entire i length of Van Buren Street until approximately 270 minutes (4 hours, 30 minutes) following the initial notification. Similar to conditions without the festival, the capacity limitations and resultant queues are primarily the result of delays occurring at the signalized intersection.of Van Buren Street
! and U.S. Route 51. Other locations where consistent vehicle queueing is indicated are the same as for summer weekend l
non-festival conditions. At most of these locations, the queueing continues for up to 30 minutes longer than it would for an evacuation without the Apple and Pork Festival. , I i t 4 f ll78/0087h 6-17
- 7. SUPPLEMENTAL ANALYSES 7.1 General Supplemental analyses related to evacuation of the Clinton Power Station EPZ have been conducted. Access Control Locations have been identified to restrict access into the area within approximately ten miles of the plant during an emergency. Also, potential mitigating measures have been identified to more effectively manage the traffic flow anticipated from an emergency evacuation of the EPZ.
7.2 Evacuation Access Control Locations Table 7.1 lists the identified Access Control Locations for the 10-mile EPZ. These locations were developed based upon
~
a detailed review of the Clinton EPZ transportation network, and are identified on Figure 7.1. These 56 control points will l be staffed by State, County and local emergency services and law enforcement personnel, as available, for the purpose of restricting unauthorized access into the potential hazard area. 7.3 Evacuation Traffic Management Locations and Other Potential Mitigating Measures The NETVAC simulation model output was examined in detail - to identify key intersection locations where vehicle queueing and delays may warrant traffic management during the course of an evacuation. The locations of vehicle queueing, or congestion, which would be anticipated during an evacuation are illustrated in Appendix 7, for evacuation of the entire EPZ under winter weekday and sudmer weekend fair weather conditions. 1178/0078h 7-1

= - Traffic Management Locations FIGURE 7.1 (continued) - INSERT 1 ' ACCESS CONTt10L AND THAFFIC MANAGEMENT LOCATIONS IN THE CITY OF CLINTON
The responsibility for both traffic and access control during an evacuation of the Clinton Power Station EPZ will be the shared responsibility of State, County and local emergency services and law enforcement personnel, as available. The specific priorities and procedures which will be used in staffing the Access Control Points and Traffic Management Locations are identified in the County RERPs. All of the previcusly identified Access Control Locations would also serve as Traffic Management Locations, since personnel stationed at these areas would assist in the efficient movement of vehicles outside the area. In addition to these Access Control Locations, additional locations have been identified within the EPZ where traffic management should be considered. These locations represent areas where traffic control personnel ' should be stationed to reduce vehicle conflicts and promote progressive movement through the area. The recommended Traffic Management Locations, also identified in Figure 7.1, are key I areas where significant traffic congestion would be anticipated
- during the evacuation process. A list of these locations is as follows
Location
- No. Location (57) Clinton Power Station Access Road at State Highway 54
- (58) Randolph Street at State Highway 54 (59) Center Street at Woodlawn Avenue and U.S.
Highway 51 (60) State Highway 54 at Main Street (61) State Highway 54 at State Highway 10 and Van Buren Street (62) Madison Street at Van Buren Street (63) Van Buren Street at U.S. Highway 51 (64) Walnut Street at Webster Street A more comprehensive list of Traffic Management Locations for the Clinton Power Station EPZ is presented in the County RERPs. , l

The stationing of traffic controllers at these Traffic Management Locations would not be expected to significantly reduce the time required to evacuate the EPZ, since the time estimates are most influenced by the various preparation and mobilization times. However, controllers at these key locations would reduce the number of vehicle conflicts and promote more progressive movement through the area. The traffic controllers would also act to instill confidence in evacuees by directing evacuating traffic in the most efficient manner possible, and by being available to respond to unpredictable or changing events. h T i ll78/0078h 7-7 u
