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

services. ~ Some of the outside emergency services include the South Carolina Highway Patrol, County Sherif f's Office, County Civil Defense Agencies, and j
Local Fire Departments. Notification by outside -agencies will be performed-f-
by utilizing vehicle sirens,. horns and door-to-door warning.

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-

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 letter dated 4 March 1980:
d 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.

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, sgp)
