The~ estimated. population within the ten mile radius of the plant is  :

- based on' an actual house count conducted during the month of February,1980.

The _ population' figures are based on 4 persons per household.

The ten mile area surrounding the Summer Station is primarily a rural area. A large number of roads within this area are capabie of handling 55 mph

. speeds. For purposes of this report, 40 mph speeds were used in the evacuation

~

time estimate. Primary evacuation method used was by private automobile since

- the area is primarily a rural area and mass transportation facilities are not l l

available.

Notification is via local radio and T.V. facilities, and outside emergency ]

services. ~ Some of the outside emergency services include the South Carolina j Highway Patrol, County Sherif f's Office, County Civil Defense Agencies, and Local Fire Departments. Notification by outside -agencies will be performed-by utilizing vehicle sirens,. horns and door-to-door warning. The notification f-times are 1 msed on local and state personnel being on ready standby to perform 4

required notification.

There are no special facilities (e.g. , hospitals,. nursing homes) within the ten mile radius of-the Summer Station. Facilities such as schools are not included in the evacuation estimates, since bus and private transportation is-

- provided _ or close at.; hand for schools in session or special activities. . - ,

to verify evacuations.

11 March 1980 SUBri:T: SCE&G EVACUATION TIME ESTIMATES TO: SCE&G V.C. SUMMER HUCLEAR STATION ATTN: MR. K. E. BEALE EMERGENCY COORDINATOR 1-The following comments are submitted as per your request based on your d

letter dated 4 March 1980: .

1. In studying the basis considered in evacuation time estimates, it ap-pears that certain presumptions have been established which are un-realistic and or non-existant, these are:
a. That facility operator has an established " fail safe" system for notification of state and local government relative to a situation that may or does require evacuation -- no such capability exists at this time. ,
b. That population notification is via local radio and T./. facilities.

This appears to be in conflict with Appendix 3 of NUREG-0654 (3-1) which states, "A system which requires the recipient to turn on a radio before a signal is received is not acceptable".

c. Use of "outside emergency services" is impracticat,le due to their unavailability on a continuous basis (Page 27, and Appendix 3, NUREG-0654), due to their day-to-day commitments. Outside emergency services e would not be on'" stand-by" on a continuous basis to provide door-to-door warning within the required 15-minute time frame. Utilization of .

vehicle sirens might be in conflict with enemy Tttack, tornado, or other emergency signals.

.d. Primary evacuation method is based on privately owned vehicle - POV.

Some families may not own vehicles or the vehicles may not be opera-tional or available' depending on time of day.

e. Figure - 1, " Estimated resident population within 10 miles". The 90

- Area '(9) being considered for evacuation includes portions of not only Lexington County, bet also Newberry and Richland Counties. 0nly i sectors SSW and S of Area 9 are located in Lexington County. Area 5, 0-5 mile radius is not.in Lexington County. Evacuation areas / sectors of 900 might t: ccsiranie ir 4-high',7 mulated areas so as  : ;c "t -

i e

a city. Spt i'.r/."i arcar r :  : mlic-ta: 4:rnc- -ir"- l must plan for evacuation of jurisdictions other than its own. l

f. flotification and evacuation estimates postulated for Area 9 may be reasonable based on facility operators experience. However, these estimates have not been verified by local government. Under " actual conditions", estimates may well be longer due to lack of emergency ~

service personnel being available to go door-to-door.

Dear 14r. Beale:

I have reviewed the SCE&G Co. evacuation time estimates within the ten mile area surrounding the V. C. Summer Nuclear Station.

For the most part, I concur with the time estimates for "Best Evacuation", " Adverse Weather Evacuation", and " Evacuation Confirma-tion", however, I would like to comment on the following:

These are based on an estimated four persons per household and assumino every house has an auto in operable condition. ~

I am sure we will have to have more factual information on these conditions prior to a final evacuation plan.

I do not think enough time has been allowed for " notification"

. with present equipment, system, and personnel. You state that means of notification will be by Radio, T.V. , and out-side Emergency Services. I do not feel that radio and T.V. will reach a large percentage and we will have to rely heavily on outside emegency services. These services will -

not always be on Ready Standby , and will require time to reach the affected area to be effective.

I_ fee 1 notification is the big problem that we need to work on immedi-ately to meet NRC time frames.

Mr Ken Beal Virgil C. Sumer Nuclear Station Post Office Box 88 Jenkinsville, South Carolina 29065

Dear Mr. Beal:

As per your letter of request dated March 4,1980, you will find my coments relative to your evacuation times listed below:

1. The traffic flow of evacuee vehicles to be sustained at 40 mph in areas 5-6-9 & 10 is probably the best that we could expect under actual conditions.
2. Notification time in areas 5-6-9 & 10 will probably .

be shorter than estimated.

3. Confirmation times which are shorter than notification times posa a situation bearing closer study of notification times.

If I or the Public Safety Department may be of further assistance, please call promptly.

Sincerely, .
