Subject:

Docket No. 50-362 14 Day Follow-up Report San Onofre Nuclear Generating Station, Unit 3 On June 7,1994, Edison provided a non-emergency, twenty-four hour notification to the NRC reporting the discovery of a condition that was not in strict conformance with our physical security plan (PSP) (NRC Operations Center Log #

27364). In accordance with the requirements of License Condition 2.G of License No. NPF-15 for San Onofre Unit 3, this letter provides the required 14 day follow-up report.

On June 6,1994, at approximately 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br />, Edison discovered a cabinet containing wiring for the security computer system which was not fastened closed in accordance with the requirements of Section 6.5 of the physical security plan (PSP). While this cabinet was locked closed with a " file cabinet" type lock, the PSP for San Onofre Unit 3 requires cabinets containing security-related wiring terminations to be either 1) alarmed with tamper switches,2) welded closed, or 3) secured with one-way fasteners. Therefore, Edison has concluded that this condition was not in conformance with the PSP.

Within 10 minutes of this discovery, Edison initiated a compensatory one hour patrol of the affected cabinet. This cabinet was subsequently fastened closed with one-way screws and now conforms with the requirements of the PSP. Edison evaluated this condition and determined that unauthorized or undetected access to plant protected or vital areas could not have occurred due to this condition. The security equipment vendor, Electronic Systems, USA, has independently agreed with our findings. Therefore, there was no safety significance to this condition.

2-i in preparing this 14-day follow-up report, Edison noted that the security-related reporting requirements of License Condition 2.G of License Nos. NPF 10 and NPF-15 for San Onofre Units 2 and 3, respectively were duplicated by the reporting requirements of 10 CFR 73.71, Appendix G. In this case,10 CFR 73 would characterize the condition described above as a 24-hour log entry, to be submitted to the NRC in a quarterly report. Therefore, Edison believes the security-related reporting requirements of this License Condition are not required. ,

As a result, Edison will be submitting an amendment application to the NRC requesting removal of this duplicate reporting requirement.

If you have any questions, please let me know.
