~- 1. INTRODUCTION I
h 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 F studies provide licensees and State and local governments
" site-specific information helpful to protective action a 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 round 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 Evaluction 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 tha evacuation time estimates for the
- Clinton Power Station EPZ. 'his report will be provided to State and County officials for their use in the event of an emergency.

1 The evacuation time estimates have been developed using t
. ( ,) 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 Appen._x 4 of NUREG-0654, Rev. 1.
These evacuation times represent the times required for
~
completing the following actions:
e.
- 1. public notification; a 2. preparation and mobilization; and
- 3. actual movement out of the EPZ (i.e., on-road travel time, including delays associated with vehicle queueing).
~
Evacuation confirmation times have also been estimated and are
- presented in Section 7 of this report.
1.2 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 Clinton 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.

- f. NRC regulations define the Plume Exposure Pathway
,_s emergency.
,() 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 x Creek in Macon County; Downs and Empire in McLean County; and
~
s Blue Ridge ahu 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 jurisdictions or man-made features (e.g., highways, railroads, canals, etc.). This determination was made due to the fact that the EPZ does not exhibit strong topographical features (e.g., streams, mountains, rivers, etc.) other than Clinton -
Lake across the middle of the area, which could consistently serve as boundary segments.
- 10CFR, Section 50.47(c)(2). The NRC provides further guidance for defining the Plume Exposure Pathway EPZ in NUREG-0654, Rev. 1.

~
Supportive-evider.ce for the use of political jurisdictions n 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, politicci 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 r
and preparation.
In cases where the local political jurisdictional boundaries were not reasonably near the 10-mile radius of the
() Clinton Power Station, attet. pts were made to use man-made features as a boundary basis. In such cases, highways were
.. used 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 boundary follows County Highway 5 (Deland/ Farmer City Blacktop) south from Salt Creek to the Creek /Monticello Township boundary, excluding the city of Deland. It then follows the Creek / Willow Branch Township boundary for approximately seven miles to the junction with Route 48. The EPZ boundary.then turns southward along Route 48 for two miles before traveling westward for about seven miles to ,the Friends Creek /Maroa Township line. It then follows this township line northward for about two miles 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 six miles before following the entire length of the western borders of Texas and Clintonia Townships toward 4619C 1-5

western border of Wapella Village and continues northward along
- Route 51 to the McLean County line. It then follows an eastward path along the McLean Counby line for about three miles before turning northward for two miles along the Randolph/ Downs Township boundary. The EPZ boundary then heads eastward along Route 136 for approximately ten miles until its junction with Interstate Route 74. It then follows Interstate Route 74 toward the southeast to the McLean/DeWitt County line. Finally, the Clinton EPZ boundary follows a southward path along the eastern border of Rutledge Township before meandering 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:
F Radius . Area
() about 2 miles about 5 miles four 90 four 90 U
sectors sectors U
about 10 miles (EPZ) four 90 sectors about 10 miles (EPZ) entire EPZ Evacuation of the area out to two miles of the Clinton Power U
Station would be accomplished on a 360 basis and would be included in the evacuation of any portion of the EPZ.
Accordingly, only one 0-2 mile Analysis Area has been evaluated.
Evacuation Analysis Areas have been defined to correspond to the distance and sector designations listed above. In addition, the geographical areas defined by that portion of DeWitt, McLean, Platt and Macon Counties within the EPZ have been included as additional Analysis Areas. This resulted in 14 evacuation Analysis Areas (one 0-2 mile Analysis Area, four 0-5 mile Analysis Areas, four 0-10 mile Analysis Areas, DeWitt County, McLean County, Platt County, Macon County and the O 4619C 1-7

. 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 6 through 31).
o The peak estimated employment level at the Clinton Power Station,
(
a Roadway geometric and operational data were f
collected by HMM Associates field crews during f May 1984 County highway maps obtained from the Illinois Departm'ent of Transpor.tation were also reviewed.
o Roadway and intersection approach capacities were
- calculated by the NETVAC computer model using algorithms developed from the Highway Capacity Manual (Reference 4), and relationships identified in the Interim Materials on Highway Capacity (Reference 5).
o Pre'paration and mobilization times have been developed for each population sector. These times were based upon discussions with IPC and 4620C 2-1
-w'- t-w I , . - _ _ _ . _ . , . _ .
" (f 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 tne rompilation and selection of these preparation t.ad moollization times.
o Vehicle occupanc) rates for the various population sectors were based upon (1) discussions with County emergency services officials and representatives of
- the various special facilities witnin 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.
0 It is assumed that subsequent to initial notification, all persons within the EPZ will evacuate. Evacuation of the EPZ will be considered complete after all evacuating vehicles are outside of the EPZ.
o The general public will be evacuated through Reception Centers to Host Areas outside of the s potential hazard area. Children from all schools i .G 4620C 2-2
. - , - e % , , e -. . .-
)
within 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.
4
- 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 unautnorized access into the EPZ.
o Transportation for non-auto-owning households will be furnished through rides with neighbors, friends 2
() and relatives, or througn coordinated efforts by State and County emergency services officials.
s o Adverse weather refers to snowstorms which would reduce roadway capacities by 30 percent during winter conditions, and sudden rainstorms which would t' reduce roadway capacities by 20 percent during the summer.
2.3 Summary of Methodology The computer simulation model used to perform the evacuation time estimate procedure is referred to as the NETVAC program. This is a proprietary 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 4620C 2-3
[
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 tne detailed distribution of vehicle demand.
o The model considers fundamental physical and operational characteristics of the evacuation road network.
o The model accounts for the dynamic characteristics of evacuation traffic flows.
r-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 scenarios occurring at different times of day.
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.

.y _
b The NETVAC program is a traffic simulation _model which'
- V uses. traffic flow relationships to calculate and record traffic l densities, speeds, flows, queues and other relevant information
- . -througnout the evacuation process. Traffic is first entered at 1
designated. points (entry nodes) in the highway network. At-every simulation interval, the model processes vehicles from P links (road segments) entering an intersection to the links
- emanating from it (outbound links or evacuation routes). The model employs a sophisticated list processing method to
! represent the evacuation as a series of links and nodes (intersections).
The NETVAC model includes a dynamic route selection
- feature wnereby drivers' choice of outbound links, at every intersection, is cased on two criteria:
[
i b 1. The degree to which an outbound link leads away from i; the plant, or the direction of specific evacuation routings where such plans exist. ;
E I 2. The traffic conditions on the autoound links (i.e.,
I travel speeds and presence of vehicle queueing or f congestion).
L a
The roadway and intersection approach capacities
! calculated oy the NETVAC program are cased upon data and
! traffic flow relationsnips presented in the Highway Capacity !
I' Manual and the Interim Materials on Highway Capacity . Due to i
j the dynamic route assignment mechanism, approach capacities are
[
updated at each simulation interval to account for potential ;
j changing turning movements. The intersection control options !
which can be specified with the NETVAC model include
- intersections witn traffic signals and priority control
[ intersections (i.e., stop or' yield signs).
! The core of the NETVAC program is the simulation l
subroutine. This part of the program executes a given number of procedures at user-specified simulation intervals. The ;

l simulator includes two major logical units: the link pass and
,7 -
_ ( ,) tne node pass. The link pass calculates the numoer 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
- weatner 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.
~ Os 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 during summer periods where capacities are reduced by 20 percent (Reference 33).
The various population components which have been incorpo-rated in the evacuation conditions modeled are summarized below:
- 1. Winter Day: This situation represents a typical day period during the winter when school is in session and the work force is at full daytime levels.
Assumptions on the population levels for this condition include the following:
o Permanent residents within the EPZ will evacuate from their place of residence;

- 3. POPULATION AND VEHICLE DEMAND ESTIMATION
\
-G.
.("~)
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 distrioution of the population to be evacuated. The second step'was the
- determination of tne 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 consider' u permanent residents, transients, and persons in specia. facilities (such as school and medical facilities, nursing homes, etc.).
The .athodology used to deve' lop the total population and
~
venicle demand estimates within the Clinton Power Station EPZ incorporates intrinsic double-counting. For example, it is reasonaole to assume that a portion of the id'entified employees within the area and visitors to recreational areas are also permanent residents within'the EPZ. In addition, school 3 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 snort, 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 witn one less passenger in tne car).
In Sections 3.1, 3.2, 3.3 and 3.4 population totals are presented for 22-1/2 U sectors, at one-mile increments for the
_ Clinton Power Station EPZ. The population totals by Analysis
. Area are summarized in Section 3.5.
3.1 Permanent. Residents Permanent residents are defined as those persons having year-round residences within the Clinton Power Station EPZ.

, Permanent population and nousing unit estimates for the area ,
,- ( ,) ware based upon data presented by the 1980 Census of Population l Gad Housing and a review'of County Highway and U.S. Geological
}Jrvey 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 tnat one vehicle would evacuate from each
~
permanent resident household. This assumption is consistent n with empirical data (Reference 34) indicating the tendency of evacuees to evacuate, where possible, as a family unit.
~
L The 1980 Federal Census data included information on the average numoer 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 s
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-autom owning households will be furnished through rides with neighbors or through 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 cased upon several factors, including the type and

. study, the same vehicle occupancy rate (i.e., one vehicle per
.. nousehold) developed for the auto-owning permanent residents was.used to develop vehicle demand estimates for the non-auto-owning permanent' residents, Tnis assumption was used since it provides the most realistic representation of evacuation i 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
() ootained 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 35). 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 througn a 4621C 3-4 5

\- ' 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
~w ithin the EPZ were also verified through a telephone survey conducted by HMM in May 1984. A listing of major hotels / motels and recreational areas within the EPZ is also presented in Appendix 3. Figure 3.3 presents tha total transient population within the EPZ in rose format.
For purposes of estimating total vehicles associated with tre 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 roc.m 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 I 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 l residents of the Clinton Poiver 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.

Q 3.4 Special Facilities The special facility population segment includes persons in scnool, hospital, nursing home or jail facilities wno may require special transportation considerations during an evacuation. j The population (verified by HMM through a telephone survey j conducted in June, 1984) and vehicle 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 amoulance. For schools, the vehicle demand was calculated based on 60 students per bus and one staff member per vehicle (Reference 36). Figure 3.4 presents the special facility population totals, Dy sector, for tne Clinton Power Station EPZ. Appendix 5 includes maps locating these special facilities witnin the EPZ.

These totals represent peak population levels for permanent residents, seasonal residents, transients and persons in special facilities. A description of the population within each Analysis Area follows:
Analysis Area 1 Analysis Area 1 includes a portion of Harp Township bordered mainly by Clinton Lake and a small portion of DeWitt Township. There are 88 permanent residents in Analysis A,rea 1 and no seasonal residents. The work force population includes the employees at the plant. In addition, a peak. population of 9421 at various Clinton Lake recreational areas exists during

,_ 4 THE EVACUATION ROADWAY NETWORK
, I
)
r \m /
4.1 Network Definition N In order to estimate evacuation clear-times, an evaluation of the roaoway 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:
- 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
{
L was reviewed with County ESDA officials. The traffic network elements considered in the evacuation modeling consist of the major streets and intersections witnin 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. Route 51 and State Routes 10, 54 and 48. l o Collector Streets are links between residential areas served by local roads and arterial streets.
l These are characterized by lower design standards
(T and frequent stops at minor intersections. Examples
\n,] ,
4622C 4-1 l l
_ . _ . . , . - - . - - _ ~ ._ -
of collector streets include Birk Beck Road (County h
Highway 21) in Harp Township, as well as Long Road
-(County Highway 15) and White Pigeon Road (County l Highway 5) in Creek and Nixon Townsnips,
- 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.
y 4.2 Evacuation Route Descriptinns p
The primary Reception Center locations to be used by evacuees will De located in the cities of 'Bloomington to the-nortn, Gioson City and Champaign to the east, Decatur to the
~
south, and Lincoln to the west of the Clirton Power Station EPZ. The primary evacuation routings were developed so as to permit a general radial travel pattern away from the Clinton '
Power Station, toward the Reception Centers. Descriptions of v the major evacuation routes for each of the previously identified evacuation Sub-Areas are outlined b610w:
Sub-Area 1 Local routes to:
o Route 54 East toward Gibson City; o Route 54 West toward Lincoln; o Route 10 East toward Champaign; o Route 10 West toward Lincoln; o County Highway 16 North toward Bloomington; and o County Highwcy 5 South toward Decatur.

'4 . 3 Cnaracterizing the Evacuation Network
- After; defining'and mapping the. links (roadway sections) j and nodesL(intersections) included in the evacuation roadway network, botn physical.and operational' characteristics of the system were inventoried. Using both field studies and
~
available maps, the geometric descriptions for each component of the network were compiled. Field data included the number s) of lanes, lane widths, shoulder widths, distances to
~
obstructions, grade, cruise speeds, traffic controls and other
- data necessary to c'alculate 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 NCTVAC model. The model, in turn, provides 'a
[ ,
listing of-the evacuation roadway network and its h
- characteristics. The network listing, presented in Appendix 6, descriDes the geometric characteristics of each. link in the i network. The listing also descriDes the possible turning
]: movements from each node and the traffic capacity of each link I in the network (vehicles per hour that can be accommodated on l each link during an evacuation). The listing of geometric
[ characteristics and ' capacities is provided by the preprocessor i

Pursuant to NUREG-0654, Rev. 1 guidance, evacuation time estimates have been prepared for the area within 2 miles of the 0
Clinton Power Station, for areas approximating 90 sectors from 0-5 miles of the station, and for areas approximating 90 sectors from 0-10 miles from the station. In addition,
- estimates have been developed for each of the DeWitt, McLean,
- Platt and Macon County portions of the EPZ and for evacuation of the entire Plume Exposure EPZ. The Analysis Areas have been defined to correspond to various combinations of the previously identified Sub-Areas. The Analysis Areas for which evacuation times have been estimated are listed below:

~
The EPZ surrounding the Clinton Power Station nas a l notification system consistent with NUREG-C654, Rev. 1 guidelines.- This system will-be used by County and State officials to alert the population to turn on their. radios and g
television sets. Pursuant to NUREG-0654, Rev. 1 guidance,
, notification messages will commence on.the designated l television and EBS radio stations virtually immediately.
Witnin 15 minutes essentially all the population -within the EPZ i I
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.
5.3 Evacuation Preparation Times and Departure Distributions It is assumed that no vehicles will begin to evacuate during the 15-minute initial notification period. It is also assumed that there will be a minimum preparation /mooilization time.of 15 minutes for all population segments. Accordingly, in the model simulations, no vehicles begin to evacuate until i 30 minutes following the initial notification. Network loading distribution assumptions for the permanent population, transient population and special facilities are described below, and summarized in Figure 5.1.

'~h Permanent Population e, \m/
Permanent residents with access to automobiles will take
- varying amounts of time to begin evacuating. Some persons will leave as quickly as possiole; 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 particular evacuation order.
- Based upon a review of the site-specific characteristics
- _ of tne Clinton Power Station EPZ, a review of available empirical data, and discussions with County and State emergency j 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 nouseholds would
~
begin to evacuate between 30 and 150 minutes after the decision to evacuate is made. It was further assumed that 15 percent of u
.() the permanent population would begin to evacuate between 30 and 60 minutes following the evacuation decision, 40 percent would Degin to evacuate Detween 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 decision to evacuate.
> 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 3.0 minutes subsequent to notification). Discussions with local emergency services officials indicate that a maximum of 30 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 / i 4623C 5-4
.:. - _ _ _ _ . _-__-_____________--__________--__-_-_L________.
fs mobilization times would be uniformly distriDuted over a (f 30-minute pr-tod. Discussions with local emergency services officials also indicate that this districution 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 the decision to evacuate.
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 u with local emergency services officials, vehicle departurc
_ times reflecting notification / preparation /moollization distrioutions, were developed.
Pursuant to discussions witn ESDA officials, it was assumed that all public schools would be evacuated via bus to
(, designated Host Centers. For school facilities, it was assumed tnat up to a 90-minute period would be required to load students orto buses, subsequent to the 15-minute notification and a 15-minute minimum preparation period. Accordingly, scnool buses were loaded onto the evacuation network from the period between 30 and 120 minutes following the decision to evacuate.
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 j facilities. Based upon discussions with County and State emergency services personnel, it was assumed that these facilities would begin to evacuate netween 60 and 150 minutes following the 15-minute notification period. Therefore, l venicles serving these special facilities would begin to evacuate between 75 and 165 minutes following the decision to evacuate.

l 5.4 Evacuation Simulation
.d Evacuations were simulated using the population and vehicle demand distribution-data, evacuation network data, and f evacuation preparation and departure time distrioution j
' assumptions discussed in previous sections. The actual simulated evacuations were performed using the NETVAC computer program. Tne 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. ;
h General Structure ;
? !
. The NETVAC program is organized in four basic units (procedures): the main program, the data procedure, the preprocessur, and the simulator. This section briefly explains t tne functions of each of these units. The main program :
^O controls the entire i execution. It starts by calling on the data procedure, which j reads in the data and the execution instructions, then calls in the preprocessor which performs some preliminary capacity l calculations. Next, the main program controls the simulation itself and the reporting of the network conditions at specified intervals. inis program also controls the rest of the reports and the length of the simulation by terminating the program I once the network is empty.. i The data procedure reads in the network, the parameters (
and the options to De used in the simulation. The data procedure performs a set of checks on tne 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) l situations are encountered.
Tne preprocessor procedure converts the physical description of each link into measures of capacity, speed and
(}
4623C 5-6 b___
m, p_
density.- For each specified type of link, the preprocessor computes two types of capacity:
. (v) o Section capacity - which is the capacity along the link regardless of downstream intersection restrictions;-and I
o Approach capacity - wnich is tne 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 venicles that can be loaded onto a link from the
~
() intersection. The approach capacity, on the other hand, limits tne numoer of cars that can actually move through the intersection. Venicles that reach the intersection but cannot
- b. .
move 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 wnile the node pass handles the transfer of flow from link to link.
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 eacn simulation interval as a function of the changing traffic conditions and directionality of the links. Drivers approaching an intersection are assumed to make a choice of outbound (away from the intersection) links
'O 4623C 5-7 M $ 9
~ _ _ _ _ - ._
based'on how fast this outDound link can get them to safety.
l
_ . , ) 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 NETVAC program reflects the two above-mentioned choice criteria through a user-supplied " preference factor" which is specified for each
> link and the speeds on each of the outbound links. In order to facilitate the explanation of the route choice mechanism, let PF) denote the preference f actor for the j-th outbound link at some intersection. In other words, the relative 'a priori' preference of link j is PF) 3 kPF where the sum goes R
over all the links (k's) emanating out of the node under
~
consideration (including j). The choice probability, or the snare of drivers choosing an outbound link j out of a given intersection at (simulated) time t, Pj (t), is determined as a function of the preference factors and the speeds on all the outbcund links as:
PF) x Uj (t) j(t) =
I kPf k x U k ID} '
where U (t) is the speed on link j at time t. It should be j
noted that driver beh'avior during an evacuation is assumed to oe myopic in that only information regarding the immediate outbound links at each intersection is assumed to influence route choice decisions.
The. Priority Treatment ,
Even under evacuation conditions, it can be expected that traffic approaching an intersection without traffic signals from certain links would have the right of way over incoming traffic from lower priority approaches. Since l't is not clear '
tnat such priority would correspond to the existing 4623C 5-8 e a e a j
i l
l 1
7_s .
intersection controls, the input to NETVAC includes a ,
q([ 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 tr.ansferred from inbound to outbound links is subject to several constraints which determine the effective capacity of the intersection. During the simulation, traffic coming in from all primary priority links is assigned to the intersection first, suoject only to the intersection capacity ccnstraints.
Lower priority traffic, on tne other hand, is restricted by both tne capacity of tne 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 neadway 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 traffic only
(,,
under one of the following conditions: first, if tnere is residual intersection capacity from the primary priority traf fic, flow can be emitted into the intersection from 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" effects.
Capacity Calculations The capacity of a transportation facility is the maximum flow tnat can travel along the facility. The NETVAC program determines capacity in two stages: first, 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 A
,\-)
4623C 5-9 4 +
movements affect the maximum volume of traffic processed along
,-q
() each link into its downstream intersection.
The capacity calculations are cased on the Highway Research Board's Highway Capacity Manual. Following this reference, the section capacity is calculated in the prepro-cessor for links with and without physical separation between opposing directions while the approach capacity is calculated as a function of the physical conditions (width, par!<ing ,
turning pockets, etc.), environmental conditions (area type, peak hour and load factors), traffic characteristics (traffic mix and percentage of turning movements), and approach type.
Tne capacity of the i-th approach coming into an intersection at simulation interval t, C g (t) is given by:
Cg (t) = C 1
x AL(t) x AR(t) where C i is the standard capacity of link i calculated by the preprocessor and AL(t) and AR(t) are the correction factors for
() left and right turning movements, respectively. These correction factors are a function of tne percent of turning traffic, the approach width, and parking allowance, and do not apply when the turning traffic is using special turning lanes or turning pockets.

- 6. ANALYSIS OF EVACUATION TIMES
(.
- s ,
6.1 Evacuation Time Estimate Summary Evacuation time estimates for each of the evacuation 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:
r Analysis Area 1--0-2 Miles (Sub-Area 1)
A large portion of the vehicles evacuating this Analysis es 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 150 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 30 minutes) for all time and weather conditions. The most significant portion 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 Route 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 Evacuation of Analysis Area 2 (Sub-Areas 1 and 2) out to l five miles from the plant would include mostly vehicles associated with Clinton Power Station, as well as a large summer. weekend transient recreational population at Clinton i
Lake. The permanent resident population would be only nominally higher (an increase of approximately 154 people) than that associated with Analysis Area 1. The estimated fair weather evacuation time for winter weekday, winter night, summer weekday and summer weekend conditions is 150 minutes (2 E hours, 30 minutes). These times are primarily influenced by
- the time associated with preparation and mobilization activities.
. The estimated adverse weather evacuation time is 155 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 35 minutes) for winter weekdays and summer weekend conditions. The reduced roadway capacities associated ,
with both rain and snow adverse weather conditions has only a slight effect on evacuation times for this area. Once again,
) the only location where intermittent vehicle queueing occurs is along the Clinton Power Station main access road approaching its intersection with Route 54.
0
- Analysis Area 3--0-5 Miles, 90 NE (Sub-Areas 1 and 3)
Analysis Area 3 includes the Clinton Power Station site, the Clinton Lake recreational population and a small number of permanent residents. The estimated fair weather evacuation ,
time for this case is 150 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 30 minutes) for winter weekday, winter night, summer weekday and summer weekend conditions. Again, the most significant influence on this total evacuation time is the preparation and mobilization time period associated with the permanent population..
The adverse weather evacuation time for Analysis Area 3 for both winter and summer conditions is the same as for fair weather conditions, or 150 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 30 minutes). The 4624C 6-3

weather conditions, exceed vehicle demands.
l' Analysis Area 4--0-5 Miles 90USE (Sub-Areas'1 and 4)
Evacuation of this Analysis Area includes vehicles associated with plant employment at Clinton Power Station, transient recreational population at Clinton Lake and permanent residents. It also includes the villages of Weldon and DeWitt. Both recreational and permanent resident populations are higher than for the 0-2 mile evacuation scenario.
The maximum estimated evacu..:on time for Analysis Area 4 under winter and summer weekday, fair weather conditions is 165 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 45 minutes). This time is largely the result of the. time associated with the preparation and mobilization of the permanent population. However, intermittent vehicle-
} queueing is evident along Randolph Street and along Old Clinton Road. Capacity deficiencies along these roadways are
() responsible, in part, for the estimated evacuation times being somewhat higher than for Analysis Areas 2 and 3.
r The estimated evacuation time for nighttime and summer weekend conditions is 155 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 35 minutes). This time is influenced primarily by the preparation and mobilization time associated with for permanent residents.
The adverse weather evacuation time for this area is 170 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 50 minutes) for winter conditions and 155 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 35 minutes) for summer conditions. The l reduced roadway capacities associated with adverse weather have more of an effect on evacuation of Analysis Area 4 than for i
Areas 2 or 3.

~
evacuating vehicles are associated with the plant work force and recreational population at Clinton Lake and Weldon Springs.
The estimated evacuation times for Analysis Area 5 are identical to those associated with Analysis Area 2, as indicated in Table 6.1. The most significant portion of the total evacuation time for fair weather conditions is attributable to preparation and mobilization times. The reduced roadway capacities and travel speeds associated with the summer and winter adverse weather conditions only slightly increase the total evacuation time.
0 NW (Sub-Areas 1, 2, 6, 7 and Analysis Area 6--0-10 Miles, 90 17)
Evacuation of Analysis Area 6 includes a significant ,
permanent resident, recreational and work force population.
Permanent residents of the City of Clinton represent a major
) portion of the permanent resident population within this area.
It is estimated that evacuation of this area during all fair weather conditions would take 180 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />). Vehicle queueing and associated delays would occur throughout the evacuation period, particuarly along Van Buren, Center and Madison Streets in the City of Clinton. Therefore, capacity restrictions along several evacuation routes within the City of Clinton are the primary influence on the total evacuation time for Analysis Area 6.
Adverse weather evacuation times for Analysis Area 6 are 215 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, 35 minutes) for winter (snow) conditions and 185 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, 5 minutes) for summer (rain) conditions. The reduced roadway capacities and travel speeds associated with the adverse weather conditions significantly affect the total evacuation time for snow conditions. The evacuation time for both the fair and adverse weather conditions are influenced primarily by roadway capacity O

This Analysis Area consists ofLthe same total recreational and work force population as the corresponding 0-5 mile. case (i.e., Analysis' Area 3). Permanent population is slightly higher for the 0-10 mile case. The estimated fair and adverse weather evacuation times'of 155 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 35 minutes)
- are.only five minutes longer than those associated with the
~
corresponding 0-5 mile case, as shown in Table 6.1. These evaucation times are all influenced primarily by the
- preparation and mobilization times of the permanent resident population. Intermittent vehicle queueing is indicated along the Clinton Power Station main access road at times of peak daytime plant employment; however, this does not significantly ,
affect the total evacuation
- times.
( Analysis Area 8--0-10 Miles. 90 0 SE (Sub-Areas 1, 4, 10, 11, 12 and 13)
,, Analysis Area 8 has a larger permanent resident population than the corresponding 0-5 mile case (Analysis Area 4). The remaining population, consisting of the Clinton Power Station work force and Clinton Lake recreational population, is exactly the same as for the corresponding 0-5 mile case.
The estimated evacuation time for daytime fair weather conditions is 170 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 50 minutes). Vehicle queueing is indicated throughout most of the evacuation period along Randolph Street in the Village of DeWitt. Similar queueing also occurs along Old Clinton Road which is a minor access road to the plant, from DeWitt. The evacuation time under daytime conditions is governed by the preparation and mobilization time of the permanent residents as well as by
~

The estimated evacuation time for night and weekend fair weather conditions is 160 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 40 minutes). There is minimal queueing under these conditions and the evacuation time is influenced primarily by the preparation and mobilization time of permanent residents.
For winter weekday, adverse weather (snow) conditions, the estimated evacuation time for Analysis Area 8 is 175 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 55 minutes). It is estimated that evacuation of the area during a summer weekend, adverse weather (rainstorm) period could be completed within 160 minutes (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, 40 minutes). The reduced roadway capacities and travel speeds associated with the winter day, adverse weather result in the slightly increased evacuation times (compared to fair weather conditions).
4 Analysis Area 9--0-10 Miles, 90 SW (Sub-Areas 1, 5, 14, 15 and 16)
(v The population associated with Analysis Area 9 consists predominantly of plant work force during the day, permanent residents at night and the transient recreational population of Clinton Lake and Weldon Springs State Park on weekends. The total population for each time period is not much greater than that associated with the corresponding 0-5 mile case (Analysis Area 5). The estimated fair and adverse weather evacuation times are all within five minutes of the times for the corresponding 0-5 mile scenario as shown in Table 6.1. These evacuation times are all governed primarily by the preparation and mobilization times associated with the permanent residents.

Analysis Area 14--Full EPZ j 73
~'
Analysis' Area 14' includes the evacuation of the entire Clinton Power Station EPZ. For winter weekday, fair weather conditions, the estimated evacuation time is 180 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />). This time is the same as that estimated for DeWitt County. This evacuation time is influenced primarily by the capacity limitations of several sections of Van Buren Street within the City of Clinton. Vehicle queueing along the entire r
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 Route 51. Other locations where consistent queueing is indicated are as follows:
o Route 10 at Van Buren Street; o Route 54 at Van Buren Street;
() o Madison Street at Van Buren Street; ,
o Route 54 at Main Street; o Randolph Street at Route 54; o Walnut Street at Webster Street; and o Center Street at Woodlawn Avenue and Route 51.
All of these locations are in the City of Clinton except for the Randolph Street location which is in DeWitt Village.
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 6.1 presents a summary of cumulative vehicle departures from the Clinton EPZ, as a function of time, for the winter weekday 4624C 6-9 4 6

increase of vehicles leaving the EPZ during the time period between 1 and 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> following the evacuation order.
The estimated evacuation time for winter weeknight, fair weather conditions is 180 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />). Vehicle queueing that occurs during the course of this evacuation is present,
- although in a less pronounced form, at the same locations as for winter daytime conditions, except for the intersection of Randolph Street and Route 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 of DeWitt. The nighttime reduction in plant work force reduces vehicle demand along Randolph Street and 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 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, 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 wummer weekend, fair weather scenario is presented in Appendix 7. Also, Figure 6.3 t
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
(
l, for this difference in departure rates is that the large summer 4624C' 6-10 i

Under summer weekday, fair weather conditions, it is estimated that it will take 190 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, 10 minutes) to evacuate the EPZ. This summer weekday evacuation case has the second largest populacion of all full EPZ analysis cases.
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.
Evacuation time estimates for the winter day (snow) and summer weekend (sudden rainstorm), adverse weather conditions
- are 225 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, 45 minutes) and 230 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, 50 minutes), respectively. The key locations where congestion is most prevalent are the same as those identified for the fair weather conditions, although weather-related reductions in .
vehicle capacity would make the extent of vehicle queueing more si0nificant for the adverse weather cases. 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-Pase in full operation and 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 180 minutes (3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />).

These times are the same as for the corresponding' full EPZ evacuation without the Clinton By-Pass and with 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. Rather, the vehicle 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 Route 51 would not promote faster radial travel out of the EPZ during an evacuation.

7.1 General Supplemental analyses related to evacuation of the Clinton Power Station EPZ have been conducted. First, an estimate was made of the time required to confirm that the evacuation has been completed. Second, Access Control Locations have been ,
identified to restrict access into the area within approximately ten miles of the plant during an emergency.
Third, potential mitigating measures have been identified to more effectively manage the traffic flow anticipated from an emergency evacuation of the EPZ.
~
7.2 Evacuation Confirmation .
L The confirmation process determines whether the evacuation has been completed. Specifically, confirmation of the j' ~g evacuation is performed to assure that the entire population
\ss that desires to evacuate has left the area, and to assist those
~
persons having difficulties in evacuating.
" Evacuation confirmation will be accomplished by County and local emergency service and law enforcement personnel in a manner to be determined upon completion of the County Radiological Emergency Response Plans (RERPs). The actual time e associated with the confirmation process would depend on both the number of personnel and the amount of equipment available.
These resources may change significantly under various emergency conditions. Nevertheless, it is estimated that the confirmation process could be completed for the entire Clinton EPZ within approximately four hours.*
- Due to the incomplete status of the County RERPs, this estimate of confirmation time was based largely on previous HMM studies for sites having similar population distributions and roadway network characteristics. Evacuation confirmation time estimates for the Clinton Power Station EPZ can be
<~N updated following the identification of specific procedures
, . ( ,) which will be included in the County RERPs.

\
x.]
' Table 7.1 lists the identified Access Control Locations g 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 control points will 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.
7.4 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
\_s- illustrated in Appendix 7, for evacuation of the entire EPZ
~
under winter weekday and summer weekend fair weather conditions.
~
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. All of the previously identified Access Control Locations would also serve as TIaffic 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.
T'hese locations represent areas where traffic control personnel should be stationed to reduce vehicle conflicts and promote progressive movement through the area. The recommended Traffic 1

c: .
F Management Locations, also identified in Figure 7.1, are key areas where significant traffic congestion would be anticipated
' L\'( '~') ' during the evacuation process. A list of these locations is as follows:
Location
- No. Location (56) Clinton Power Station Access Road at Route 54 (57) Randolpn Street at Route 54 (58) Center Street at Woodlawn Avenue and Route 51 (59) Route 54 at Main Street
-(60) Route 54 at Route 10 and Van Buren Street (61) Madison Street at Van Buren Street
. (62) Van Buren Street at Route 51 (63) Walnut Street at Webster Street 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 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. .
