IIr ANPP-30267 ATTACHMENT PALO VERDE REQUEST FOR ADDITIONALINFORMATION REGARDING EMERGENCY PREPAREDNESS OPEN ITEM J(6) 1.
The submittal (ANPP-28685-MFQ/KEJ),
dated January 24,
- 1984, provided by APS was reviewed by the staff, and the following issues require resolutions:
(a)
The citation of the source for the evacuation speed equation used in the Palo Verde Evacuation Time Study (Study) is erroneous.
The actual evacuation speed equation used is a modified version of the cited reference.
The applicant should reflect this information in the Study.
(b)
Because the evacuation speed equation used in the Evacuation Time Study is a modified one, the applicant should reflect in the Study that the equation is only valid when demand is less than capacity.
(c)
The applicant's concept of density (i.e.,
number of vehicles per mile) assumes the nominal length of a car is 10 feet and that there will be maintained a distance of 10 feet between each car for each 10 miles per hour.
Such assumptions lead to erroneous times to clear the last vehicle from a given segment of roadway under consideration; this is because empiri-cal data indicates that people do not generally drive that close to each other.
Therefore, the applicant should choose another approach that compensates for this fact.
One example would be to utilize a two second time interval between succes-sive vehicles.
RESPONSE
(a)
Page 3, Section C, paragraph 2 of the Evacuation Time Analysis has been changed to reflect that the formula is a modified version of the formula listed in the Federal Highway Administra-tion Traffic Assignment Manual.
(b)
Page 3, Section C, paragraph 2 of the Evacuation Time Analysis makes special note that this modified formula is only valid when capacity exceeds demand.
(c)
The length of an average vehicle and the separation per ten miles per hour (refer to page 3, Section C, paragraph
- 4) were increased from ten to twenty feet.
This method was suggested during a conference call between APS and NRC staffs by Mr. Urbanik, your consultant.
The time for evacuation changed as reflected in the table (Results of Evacuation Time Analysis/
Normal and Adverse Conditions) on page V-7.
