l Evacuation Imolemntation i

1. @e EPEs represent the tine to evacuate the population using the nest efficient routes and traffic strategies. It is inadvisable, during an amrgency, to inpleant additional routes and/or extraordinary traffic strategies (such as using inbound

, lanes of I-495 for outbound service). Such attarpts will be l confused, difficult to inplanent and are unlikely to reduce the ETE.

2. If an evacuation, is going to be ra.umerded, but the Region is in doubt, it is beneficial to get the inner EPZ areas noving (Regions 9 or 5) as soon as possible, his action will minimize

, q the potential exposure of this population and the evacuated area I

g can be later expanded.

l p Accident Timeline

'Ihe ETEs are based upon the following accident tinelines

'Ihe public is notified of a SITE AREA EMERGENCY (SAE); All EPZ beaches are closed during the stauner.

Fifteen minutes later, the public is notified of a GENERAL DE:RGENCY.

• Ten minutes after the notification of the GENERAL DElRGENCY, the public is notified of an Order to Evacuate (CTE).

When the elapsed frun the SAE to the OTE exceeds the above ,

25 minute planning basis, the ETE is consequently reduced. '1his reduction in ETE is nost pronounced during the sunmer season i because the transient beach ppulation begins evacuating at the j SAE. During the sumer, any increase in the time difference between the SAE and OTE beyond the 25 minute planning basis reduces the ETE by approximately the same amount of time.

However under no circtanstances would the resulting ETE be less than 3:25.

EPZ Canmunity Clearance Times

'1he following table provides the range of clearance times (hours)  ;

( for the EPZ comunities during a Region 1 (ccmplete EPZ) evacuation. Vehicles within theso comunities either originated I

there or were passing through and ancountered congestion. It is important to note that the resident population may have evacuated substantially sooner than the times shown and that these tines i may be indicating the presence of vehicles from other comunities i caught in congestion. After the tinos shown there will be no ,

congestion but there may continue to be vehicles fran other I comunities quickly passing through. '1his table should not be used for PAR decision making. Times are provided for Scenario 1 l

1.0 PLRPOSE AND USE OF ETE HANDBO T 4

Se Evacuation Time Estinates (ETEs) represent the result of ,

an extensive and emplex evaluation process which nay play an inportant role in the respcmse to an amargency at cambrook Station. 21s sectica describes how this Hei--:1 t any be used as j a ready reference for the effective use of the ETEs. ,

1.1 Purpose of the ETE Handbook '

l.1.1 Purpose mis subsectim details who in the energency response organization this ETE Handbook is intended for and what role the -

ETE has in the amargency zorponse.

1.1.2 Role of the ETE in the Baargency Response During an emergency at any nuclear power station there may be a possibility of an aWrne release of radioactive gases and particles, his radioactive material would be carried by the

+

wind and would expose people in the downwind areas. Se radiation dose that the people receive can be reduced, or totally avoided, by the tinely inplanantation of protective actions such as sheltering or evacuation. It is the prinary purpose of the amargency response effort to minimize the radiation exposure of the p?ilaticm.

Protective actions would be reoczannded when the plant status has P to the point that a there is a " potential" for a significant release of radiation. mis reoczunendation is based upon " potential" rather than an actual release of radiation so that the protective actions can be implananted in a tinely manner, preferably before a release has started. m is allows an evacuation to ri m ed with minimized risk of radiation exposure to the population.

Sheltering will rarely be the protective action of choice for the general populaticm because of the limited dose reduction prwided by the average home. ( Iarge bd1r4ngs oftan do provide significant levels of dose reduction ). Sheltering would be rec.w...ividad only in those circumstances where either evacuation is not feasible due to road conditions or the radioactive release occurred so suddenly and is of such short duration that the general populatico would receive a higher dose while evacuating.

Bus, in those situations where plant conditions could '

potentially result in a release of radioactive material (a GDERAL DElRGDCY), evacuation of portions of the anergency Planning Zone (EPZ) will likely be chosen as the aauug. late protective action. It is inprobable that this decision would be influenced by the evacuation time estimate itself.

% e analysis that develops the ETEs provides useful insights 1-1 Rev.0

~ _ _ _ __ _ _ _ _ _ __ _ . . ___ _ _ _ _ _ _

i into various aspects of the evacuatim, including: routes, access '

O control, and resource needs for general and Wal populaticrw,.

'Ihe traffic strategies have been developed to minimize the thne to evacuate and are inplemented in accordance with the traffic '

nanagement portions of the MRERP, MDM and SPIC. 'Ihus, while the Im!ls are unlikely to have a direct influence cm the protective action decision, the insights gained can also assist those officials responsible for hplementing the unargency resparme.

1.1.3 Pbr nom '1his Handbook is Intended

'1his Handbook is intaded to support these individuals in the amargency response organizaticm: -

Who ney require an Evacuation Tina Estinate as an input into the detamination of a protectivo action reoczanandaticn.

• Who need to inplanant an evacuation by indicating how the actual emergency situation they are ex:nfronting will affect the evacuation time so they nay nake the nest offactive use of their roSources.

1.2 Use of the EFE Handbook 1.2.1 Purpose

'1his subsection details the information contained in this Handbook and how it nay be used.

1.2.2 Identification of the hug.iate ETE One hundred and thirty four Evacuation Time Estimates have been canputed that cw.t.-rid to a wide range cf potential evacuation situaticns. In addition, numerous sensitivity studies have been done that analyze the effect of variations in certain ETE inputs. 'Ihis Harvihmk provides guidance en how the inputs to the ETEs are specifically defined so that the nest aa.u.vp.iate ETE can be selected. In addition, the potential effect of variations in see of the inputs is discussed. '

'Ibe relationship between the general population ETEs and the evacuation times for special populations and those dependent upon bus transportation is also detailed.

1.2.3 Reference Guide for Assunptions and Inputs

'Ihe underlying inputs and assumpticms are explained so that a better understanding of what the ETE tarweento is possible.

'Ihis section also provides insights into aspects of the general population's expected response to the immpey situation that O have been factored into the ETEs.

2.0 - GENERAL POPUIATICN ETE

'Ihis section provides guidance en which ETE should be used, the underlying anstmptions and inputs used in the UTEs and how changes in sane emargency specific variables may affect the ETEs.

(Sane of the UTEs noted in this section are not based on the latest FrEs and are included only for guidance. ) 'Ihe latest ETEs are shown on Table 2-1, EVACIATION TIME ESTIMATES. '1he HTEs detail the time necessary for the population to evacuate the '

designated Region when they are notified of an evacuation r m .- .-lation.

2.1 Variables Input at the Time of the Emergency 2.1.1 Purpose

'1he selection of the amvriate crE is based on a determination of the EPZ area (Region) to be evacuated and the circumstances (Scenario) that exist at the time of the evacuation. 'Ihis subsection details the am us iate Region and Scenario to be selected.

2.1.2 Evacuation Region (ETES Sections 8,10)

'1he Seabrook EPZ is made up of six Massachusetts cormunities and seventeen New Hanpshire acumunities. 'Ihese comunities have been grouped into seven Duargency Response Planning Areas (ERPA),

'O identified as "A" through "G". Any protective action recannendation would always treat the comunities within a particular ERPA the same. 'mble 2-2, EPZ IRPA AND REGICES, lists which carmunities are part of each ERPA. Figure 2-1, ERPA Hap, shows the geographical location of the ERPAs within the Seabrook Station EPZ.

'Ibe Regicn to be evacuated is based upon the wind direction and the seriousness of the plant's ccmdition. 'ihe nore serious the situation the farther the evacuation in the downwind direction. 'Ibe inner circle is evacuated as a precautionary measure to allow for sudden windshifts. 'Ihese Regions, centered around Seabrook Station, are of four general shapes:

• two mile circle

• two mile circle plus five mile downwind 90 degree section

• five mile circle plus ten mile downwind 90 degree section

• ten mile circle

'1hirteen Regions have been identified that approximate the potential wind directions and the four shapes identified abrne.

'Ihese regicns are identified on Table 2-2, EPZ ERPAs AND RIGICNS.

Note that Regions 2, 3 and 4 are not shown since they have been superceded by Regions 11, 12 and 13, respectively. Region 10 is not a specific region but rather represents those beach areas that would be affected by a precautionary beach closure.

2.1.3 Evacuation Scenario (LTES Section 10)

I V) %e evacuation Scenario represents those variables that affeet population distribution and road conditions. We variables used are defined as follows:

1. Season Sumer May 15 - September 15.

Off-Season h e rest of the year.

2. Day Weekend Saturday , Sunday and Holidays.

Mid-week Monday through Priday.

3. Tine Mid-day 7:00 AM to 6:00 PM.

Evening Other times.

4. Weather Good Dry roads.

Rain Fog; Wet roads, during/after rain or snow.

Sudden Rain Rain occurs within 1 hr. of OTE.

Snow Evacuees nust clear driveways or there is ice on roadways that have not been sanded.

' Dan ocanbinations of these variables have been used in the calculation of the ETEs and are shown in Table 2-3, Evacuation Scenarios. In general, the nost sbnilar scenario should be used but PAR decisionmakers are free to disregard the ETE scenarios if iq f

g better information is available.

%e LTE Sumner Scenarios only provide for the mid-day time l period. 'Ihis time period is when the beach population can be expected to be at about peak levels and results in the longest Evacuation Time Estimates. During other time periods the beach area population is rwiW frun these peak values with consequent reductions in the ETEs.

%e population level of the beach areas on good weather summer days varies approximately with the following schedules Time: SAM 2PM(peak) 6PM 9PM

% Pop.: 65% 100% 80% 85%

Sensitivity tests were performd, which reduced the beach population to as much as 40% of the reasonably expected peak.

l 'Ihe results for Region 1 (entile EPZ) and Scenario 1 (sumer l weekend, mid-day, good weather) are:

Percent Beach Area Percent Difference in ETE ,

Population Relative Relative to W at'for the Peak to the Peak Value ETE Value of Beach Area Population

_ 100 (peak) 7:40 0.0 80 7:05 -7.6 60 6:35 -14.1 40 6:10 -19.6 2-2 Rev.0

i I

i c '!his study shows that for evacuation situations whem the

(

D) critical rath population, (i.e., the last population to leave the EPZ), originate their trips frun the beach ama, the ETE is reduced in piux.=mt by about cne thLtd the percent reduction in beach area population, over the indicated range.

2.2 Inputs Used In % e ETE Calculation .

2.2.1 Purpose i

%is subsection details the inputs that have been usM in the ETE calculatiCm. %ese variables are based upon SeabIcok '

Station EPZ research and traffic engineering practices. his infonnation is provided for background purposes.

2.2.2 Population Data (ETES App. E,M)

! We ETE calculation is concerned with the number of evacuating vehicles as opposed to the actual population. So both i the population and the number of people per car have been evaluated. S e total population is made up of three groups:

pennanent residents, transient and employees. Wese population groups vary greatly for the various scenarios used in the ETEs.

Table 2-4 precents a sumary of projected 1990 population data.

Se pennanent population used in the ETE calulation is based

(' upon 1985 Massachusetts Data and 1984 New Hanpshire data. Both

\ sets of data were extrapolated to 1986 using annual growth rates for each town. mis papulaticm is considered cmstant for the various evacuation soonarios. It has been detamined that the 4%

increase in pamanent population between 1986 and 1990 would cause no material charx)e in the ETEs.

Transient population consists of beach arim transient and inland transients. W e beach area transients are based upon a count of vehicles observed on aerial photographs taken in July 1987. %e inland transient population is based on various studies done over a period of years. W e Transient population varies gmatly between the seasons and day of the week.

2ployee population is based upon data provided by the New Hanpshire and Massachusetts enployment bureaus that was extrapolated to 1986. We employee population varies greatly between weekday ard weekend and the beach enployment varies greatly with the season.

2.2.3 Evacuation Shadow (ETES Sections 4,10)

Evacuation shadow represents the portion of the EPZ population that voluntarily evacuates fran areas for which evacuation has not been reccm:nended.

For Regions (5,6,7,8,14, and 15) that extend to 5 miles fran Seabrook Station, it is assumed that 50% of the papulation that 2-3 Rev.0

is located outside the Region but within 5 miles of Seabrxx:k g) g v

Statim, will voluntarily evacuate. Furthernere, 25% of the population weata:1 outside these Regions and between 5 miles frm Seabrook Station and the EPZ boundary, will voluntarily evacuate.

For Regions [ 11,12,13,16 and 17) that extend to the EPZ boundary, it is assumed that 50% of the EPZ pq nlation outside these Regions will voluntarily evacuate. Finally, it is asstaned that when Regicri 9 and 10 are evacuated, 25% of the other EPZ population will voluntarily evecuate.

2.2.4 Accident Timeline

'1he ETEs are based upon the following accident timaline: -

'Ihe public is notified of a SITE AREA DERGDCY (SAE); All EPZ beaches are closed during the stumar.

Fifteen minutes later, the public is notified of a GENERAL DERGENCY.

' Dun minutes after the notificatian of the GENERAL DERGENCY, the public is notified of an Order to Evacuate.

'Ihe time difference between the declaration of a SITE AREA DERGDCY and the Order to Evacuate (OTE) will have an effect on the ETE. 'Ihis effect is a result of the activities that would take place at the SAE that serve to expedite a subsequent

-I evacuation. 'Ihese activities include:

• Beach closure Spcotaneous evacuation of portions of the population

• Placement of traffic guides at 'ICPs and ACPs Early preparation for an evacuation such as packing, business closure and family re-unification.

During an T==iiate GENERAL DERGDCY with an OTE, i.e.,

zero time difference between the SAE and the GE, the planning basis would lose the benefit of 15 minutes. '1he time to evacuate would be increased by about an equivalent anount of time.

When the elapsed from the SAE to the OTE exceeds the above 25 minute planning basis, the ETE is consequently reduced. 'Ihis reduction in ETE is most pronounced during the sumer season because the transient beach population begin leaving the beach area at the SAE. During the sumer, any increase in the tine difference between the SAE and OTE beyond the 25 minute planning basis reduces the ETE by approximately the same amount of time.

However under no circumstances would the resulting ETE be less than 3:25. 'Ihe following table presents scme exanples:

Tine frun SAE to OPE Reduction in 2TE 1:10 0:45 (70 min. - 25 min.)

- the beach areas at the time of the SAE notification. Vehicle trips from the inland areas are initiated 15 minutes later..  ;

'(Inland trips begin before the Order to Evacuate since it is expected that a portion of the population will evacuate  ;

cpantaneously). 1 i

2.2.6 'ICP/ACP Activation Time [ETES Section 7)

'Ihe following 'ICP and AC'. m3 mated manning times have been included in the calculaux $t the ETEs. 'Ihis was accanplished by evaluating the road nmerx and detennining alternate routes and Is:luced road capacitias that would be present in the absence of traffic guides to inplement traffic control strateglec. h IDYNEV sinulation model was then Iun; with the local traffic patterns switching from pre 'ICr sctivation patterns, with concm mitant changes in capacity, to post activation patterns as each of the 'ICPs is staffed in accordance with its priority.

L Massachusetts (SP)CJ)

Traffic control personnel are mobilized upon declaration of a S M AREA EMERGENCY and are idiately dispatched to the 'ICPs.

They begin implementing the traffic control strategies when

.o 2.2.7 Roadway Capacity.[FrES Section'3)

Road capacity is measured in vehicles per hour per lane (VPHL). For calculation of the UTEs, the capacity of evacuation routes is M M to 85% of normal capacity whenever cu gested acrditions prevail.- For at-grade (ncm-limited access) roadways, this capacity reduction represents the potential inefficient traffic operations due to a variety of factors which may prevail under emergency evacuation ecoditions, incitding driver.

uncertainty and short term traffic disruptions in a cusested traffic environment.

Capacity reductions also account for weather related yuad corxiitions. For rain and fog, rund capacity is rwhv==ri by 20%

and for snow and ice, road capacity is reduced by 25%. -

2.2.8 Returning Ccumuters [ETES Section 5)

Upon notification of the public to evacuate, people who live and work within the EPZ will be travelling hcne on roads within the EPZ. 'Ihese trips fIun work to hme were not explicitly modelled with the IDYNEV model. 'Ihe effect of work to hczne trips has been accountad for explicitly in the estimation of roadway capacity by considering their presence as inbound vehicles in estimatlag the directional split of traffic (90% outbound and 10%

inbound). In addition, their effect on capacity is tas.wsmi.ed r as contributing to the 15% reduction in road capacity whenever

-( the road segment experiences congestion.

l 2.2.9 k nugh Vehicles (ETES'Section 2]

For calculation of the ETEs, approximately 3,000 vehicles were initially placed upon the highway segments. 'Ihen for midweek /mid-day scenarios the cmputer was sugcuma.i to generate 4,400 additicnal through vehicles during the first hour and 2,200 vehicles during the second hour after the order to evacuate. For weekend and evening scenarios 2,200 and 1,100 vehicles are used for the first and second hours respectively.

3.0 ETEs FM 'IHE 'IRANSIT DEPD0ENT POPUIATICN Transit dependent Populations refer to the portion of the population that requires special transportation considerations during an evacuation. 'Ihis includes people without access to

' private cars, children while in school, hospital patients, nursing hcne residents and the Waand. 'Ihis secticn sumarizes how these groups are evacuated and relates their evacuation times to the ETEs for the general population. -

3.1 Procedure Sunmary 3.1.1 Purpose

'Ihis subsection summarizes how the transit dependent population groups within the Seabrook Statico EPZ are evacuated

- during an anargency. 'Ibe vehicles used to trensport these people are buses and Emergency Madical Service (DtS) vehicles (amhilances and ambulettes) .

3.1.2 New Hampshire (ETES Section 31]

Protective actions reconnended for all transit dependent pyilatione will be the same as the general population. '!his decision nay be revisited for individual facilities based upon input received fran facility nanagers. In these cases a more O' detailed evaluation of protective action reccamendations is V~ undertaken based .:pon facility specific sheltering protection factors.

At a -SITE AREA DElRGENCY buses anti EMS vehicles will travel fran their respective originating locations to the State Transportation Staging Areas (TSA). 'Ihe TSAs are lomted at the Rockingham County Ccmplex in Brentwood and the New Hanpshire Port Authority in Portsnr.uth (buses only). Fran these State TSAs they will be sent to local TSAs in the comunities where they will receive route and facility assignments. 'Ihe vehicles will be cilspatched fran tho TSAs upon notification of an ore.

3.1.3 Messachusetts (ErES Section 11]

Protective actions reccanended for all transit dependent pyilations will be the same as the general population.

At a SITE AREA D(ERGENCY bus yard managers will mobilize their drivers to the bus yards. Bnergency response personnel will first go to the Staging Area where they will be briefed and then they will proceed to the bus yards to dispatch the bus dr' ars. 'Ihe drivars will receive their briefings and assignments at the bus yard and, upon notification of an OPE, will be dispatched to their assignments in the EPZ. Buses evacuating special facilities will be dispatche1 directly to O

g these facilities fran the bus yard. Buses running general population transit dependent bus routes in the EPZ towns will be 3-1 Rev.0

dispatched to a designated Transfer Point for that town where i they will run an assigned route.

.t-During a rcpidly escalating anergency this Massachusetts p.w dare is acdified to expedite dispatch. Upm notification

- the bus drivers obtain himaa and e.<-ei directly to the canpus of- the Northern Essex Comunity College in Haverhill. 1his facility is near the Staging Area and saves the time of having the emergency respmse p.u..c. sis 1 travel to the bas yard.

Snargency response personnel brief and dispatch the drivers at the college.

EMS vehicles are dispatched to the Staging Area at a SITE AREA EMERGENCY where the drivers are briefed. Nhen an OTE has been issued they receive their assigmnant and are dispatched to evacuate special facilities and the W sind.

3.2 Transit Dependent ETEs 3.2.1 Purpose (ETIES Section 11]

1he ETEs for the transit dependent is based upon an analysis of the bus and EMS vehicle evacuatim trips. 1hese analyses are based upon the planning basis time line with 25 minutes between the SAE and OIT. Since these vehicles are mobilized to bus yards and Staging Areas when an SAE is declared, if the OPE is delayed, l then the2.e would be a cmsequent reduction in the ovacuatim tine A( / for the~ transit deperdent. - 1his snhaartion sunnarizes these analyses.

3.2.2 Analysis of Trancit Dependent ETEs (E1TS Section 11]

' She EMS vehicles are expected to be able .to mobilize quickly (in about twenty minutes) because of the esim.pucy nature of their daily tasks. 1 hen, assuming a 21/2 hour transit time to an evacuating facility (via a Staging Area) and 40 minutes to load passengers, the vehicle would begin traveling out of the EPZ within about 3 1/2 hours. Outbound travel would be controlled by the speed of other evacuating vehicles or would take about 15 mLnutes if the roads were clear. As can be seen fran the E7fEs in Table 2-1, the shortest ETE is 3:35 so the outbound ENS vehicles would always caningle with the general population and their ETE would be considered the same.

she ETEs for the buses are calculated by adiing the expected i

i 11/2 hour mobilization time to the longest (weathar adjusted) route transit time for each ccumunity. 1his analysis showed that

! the bus ETE exceedet' ihe general population ETE for Scenario 9 l (rain, off-season, evening or weekend) in Regions 7 and 9. In these cases the general population ETTE was excariaci by less than

s 4.0 IMPACT OF ETE m GGANIZATIM SMFFDG Evacuation support activities are implemented by numerous anargency response pw.mauml in Massachusetts and New Hanpehire.

'!hese personnel are, for the nost part, dilized at a SITE AREA

!!NIBGENCY to their field locatica or staging areas and they potent.fally remain there until the amargency is teminated or the evacuation is canpleted. If the energency classification nunains at an SAE for a 1.u.vL. acted period of time then the emergency response officials need to take steps to ensure the avs41aN 14ty of sufficient ntsubara of emargency response piumauel. .

4.1 Detamination of Staffing Heads In the situation where the emergency has remained at an SAE for a protracted period of time the Innbar of people paariari to implanant the evacuation should be reevaluated. 'Dtis change in the number of perm usl paalari ney be caused by the following:

• N3rmal dismissal or precautlanary evacuation of schools could reduce the number of bus drivers and reception center personnel I W .

• 'ICPs/ACPs associated with the closure of the beaches could be deactivated when these areas have evacuated or my not be needed during the off season.

O V * '1he Region potentially to be evacuated, based an wind and plant ccmditicas, may be small and require fewer er.argency' response personnel.

• Sheltering for all or part of the EPZ is the protective acticn either reccananded or under ccmsideration. ,

'Ibe time that ,=mecy response personnel can be an station, actively inglenenting the energency recgnse is quite flexible, howwar twelve or thirteen hours is uusidered reasonable. Sjnoe this is longer than the ETEr for any Reg!m or Scenaric it should not be necessary to rotate field pm.mnuel oncx an evacuation has started unless they have exceeded their radiation esposure limits. Fu mausl in a standby statufs can renain indefinitely if app.qu.iate measures have been taken for them.

• D/ACP i waial at field locations should be called back to the Staging Atta where they can be fed and get same rest. At scane field positions personnel ney be required to stay in the field, such as:

- High priority TCP/A"2 locetians

- ACPs a=wiated with beach cloeure

- ACPs associated with shelter inplanantation These positions can remain continuously active by rotating pu. .el to these locations.

It is rvmnally not considered appygolate to feed emergency response workel.3 in the EP2. If sufficivit personnel are available, then anergency wk.u.e can be put on a xotation be.ais with a portion of the he returning home to return later and relieve those that runnined.

• Bus Drivern, DtS parsannel and Route 9dh may be naintained at either bus yards or staging areas as am @ te.

p At these locations thase personnel can be rotated and or Q neintained as described above.
