NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 74 TO PROVISIONAL OPERATING LICENSE NO. DPR-13 AMENDMENT NO. 22 TO FACILITY OPERATING LICENSE NO. NPF-10 AMENDMENT NO. 10 TO FACILITY OPERATING LICENSE NO. NPF-15 SOUTHERN CALIFORNIA EDISON COMPANY, ET AL SAN ONOFRE NUCLEAR GENERATING STATION, UNIT NOS. 1, 2, AND 3 DOCKET NOS. 50-206/361/362.
1.0 INTRODUCTION
Southern California Edison Company.(SCE) (the licensee) filed with the Nuclear Regulatory Commission for the San Onofre Nuclear Generating Station (SONGS) Units 1, 2, and 3 a proposed amendment to -their 'License Numbers DPR-13, NPF-10 and.NPF-15, respectively., The amendments would approve the revision to the physical security plan entitled "San Onofre Nuclear Generating Station Physical Security Plan," dated August 1983 (transmitted by letter dated August 9, 1983) with errata pages dated December 1983 (transmitted by letter dated December 16, 1983).
A Notice of Consideration of Issuance of Amendments to Licenses and Proposed No Significant Hazards Consideration Determination and, Opportunity for Hearing related to the requested action was published in the Federal Register on December 21, 1983 (48 FR 56510).
No request for hearing and no comments were received.
2.0 EVALUATION Part 73 of 10 CFR 50 specifies requirements for a physical protection system at fixed sites.
Physical security systems shall be established and maintained by the licentee in accordance with security plans approved by the' Nuclear Regulatory Commission.
In its submittal dated August 9, 1983, as supplemented December 16, 1983, SCE made 15 significant changes to their approved physical security plan.
The licensee reformatted the plan to follow NUREG-0908, thereby eliminating much of the redundancy and extra detail contained in the previous plan.
The basic level of security at the site was not altered by this change.
A number of changes were made related to security implementing procedures including:

-PDR
-2
- Redefining the duties of a guard tower officer;
-.Implementing a security procedures management system;
- Changing requalification time from six months to 12 months for security force members; Adding details regarding package search; Removing extraneous details regarding security training and equipment;
- Decreasing key inventory frequency from 6 months to annually;
- Reducing patrol frequency; Modifying personnel search procedures; and Providing additional details regarding audits.
In another change category the licensee combined the protected area of the three units, provided a more detailed description of alarm line supervision; incorporated specific compensatory measures for failed or bypassed intrusion detecting zones, realigned the designation of vital and non-vital equipment, and provided additional duties for the central alarm station operators.
)
SUMMARY
The following summarizes the staff's findings regarding the proposed changes:
"'The format changes improved the inspectability of the security plan and made the plan easier to usefor those charged with its implemen tation.
o The redefinition of guard tower officer duties provided for more reliance upon the assessment capability of the guard tower officers and their employment as compensatory posts.
o The implementation of a security,procedure management system provided for a more rigorous commitment to a system that was"currently in use.
0 The change in requalification time from 6 months to 12 months is consistent with the requirements of Appendix B to 10 CFR 73.55.
o The additional details on procedures for package search will improve the effectiveness of the search.
-3 o Details regarding security training and equipment properly belong in the training and qualification plan and site procedures. A general security plan commitment is sufficient.
o The decrease in key inventory modified an over-commitment on the part of the licensee that was not cost effective. The new inventory commitment is within the acceptable limits of the guidance.
o The reduction in patrol frequency modified an over-commitment. The new patrol frequency is within the acceptable limits of NRC requirements.
o The modification of personnel search procedures clarified the search program and provided commitments that were easier to inspect and to implement.
o The change in the audit commitment letter meets the requirements of 10 CFR 73.55(d)(4).
o The consolidation of protected areas eliminated the intrusion alarms and barrier between Units 1 and 2 and thus improved movement of operations and security personnel between units.
o The new description of alarm line supervision is explicit 'rather than referenced to a Federal Specification.
o Based upon a study done by the licensee and its contractor, the licensee realigned.the vital area protection program to eliminate many items that are not considered to be vital equipment. The staff agrees that the vital equipment now protected conforms to.
the regulatory definition of vital equipment as given in 10 CFR 73.2(h)(i), the 10 CFR 100 release limits and the criteria contained in Regulatory Guide 1.29 Seismic Design Classification and Review Guideline #17 Definition of Vital Areas, Revision 1.
o The identification of vital areas and measures used to control access to these areas, as described in the physical security plan, may be subject to amendments in the future based upon a confirma tory evaluation of the plant to determine those areas where acts of sabotage might cause a release of radionuclides in sufficient quantities to result in dose rates equal to or exceeding 10 CFR Part 100 limits.
o The duties of the central alarm stations operators have been increased due to the integration of all three units into one large protected area. The licensee has provided a commitment that the additional duties will not interfere with the alarm response functions.
-4 Based on the above, the staff has determined that the revised "San Onofre Nuclear Generating Station Units 1, 2, and 3 Physical Security Plan" dated August 9, 1983, as revised, continues to meet the require ments of 10 CFR 73.55 (b) through (h), and is, therefore, acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
The amendments revise license conditions to reflect the Commission's approval of revisions to the Physical Security Plan and, therefore, do not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environ mental impact. Having made this determination, the staff has concluded that the amendments involve an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR §51.5(d)(4),
that an environmental impact statement or negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of the amendments.
4.0 CONCLUSION
Since the amendments revise license conditions to reflect the Commission's approval of revisions to the Physical Security Plan, the staff has further concluded that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
