George Knighton, Director Project Directorate V Division of Reactor Projects III, IV, V and Special Projects FROM:
Robert A. Erickson, Chief Reactor Safeguards Branch Division of Reactor Inspection and Safeguards
SUBJECT:
SAN ONOFRE NUCLEAR STATION 10 CFR 50.90 SUBMITTAL This is in response to the July 24, 1987 letter from Southern California Edison Company requesting a change to the Physical.Security Plan for the San Onofre Nuclear Station. We have reviewed the proposed change, in accordance with 10 CFR 50.92, and concluded that it involves no significant hazards consideration.
A statement of our analysis is enclosed for project management use in preparation of a "Sholly" notice.
The Project Manager has obtained a TACS number for this review. Our principal staff reviewer for this action is Gene McPeek, X24968.

PFICIAL RECORD COPY
ENCLOSURE PROPOSED DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION Date of Amendment: July 24, 1987 Description of Amendment Request The proposed amendment involves a minor change in the location of a vital area boundary which slightly increases the size of a vital area.
Basis for Proposed No Significant Hazards Consideration Determination Based on the three criteria in 10 CFR 50.92, the proposed change for the San Onofre Nuclear Station does not involve significant hazards based upon the following considerations:
I. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
The proposed change affects only the Physical Security Plan which provides a basis for having assurance that acts of radiological sabotage will not significantly impact public health and safety. No FSAR accident analysis takes credit for the security provisions contained in the Physical Security Plan.
Therefore, this change does not involve an increase in the probability or consequences of an accident previously evaluated.
II. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
The proposed change to the Physical Security Plan does not alter any safety related design basis of the facility or its operation.
Therefore, this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
III.
Does the proposed change involve a significant reduction in margin of safety?
The proposed change to the Physical Security Plan does not involve a significant reduction in a margin of safety since no change is made to the plant design or operating procedures.
Therefore, margins of safety are not significantly reduced.
