Inforr# tion for seismic qualification of Oconce Emergency Power System TAR Ho: ~ ORB-1-250 Responsible Branch: ORS 1 Project Manager:
G. Zech Requested Completion Date: August 13, 1976 Licensee Response !!eeded to Meet Schedule: 9/10/76 Reviert Status: Outline of Guidance for Information Needed i
The enclosure contains the outline of the infont.ation needed for the seismic qualification report to be submitted by the licensec.
(
.Our guidance for this information covers the structural and nachanical 1
engineering aspects of seismic design. Ilowever, if this system is not protected against tornado missiles, the licensee should provide sufficient j
justification ~for excluding tcrnado protection. Any additional infor:aation
]
regarding the need for tornado protection of the Emergency Power System j
should be reviewed by the EEB.
