SUMMARY
OF OCTOBER 21, 1982 MEETING On October 21, 1982 members of the NRC staff met with representatives of Southern California Edison Company and their consultants. The purpose of the meeting was to discuss the soils properties used for the San Onofre Unit No. 1 seismic reevaluation (Systematic Evaluation Program topics II-4.F and 111-6). In April 1982, the licensee notified the NRC that backfill soil consisting of San Mateo Formation sand compacted to less than 95% Modified Proctor density was encountered during ongoing modifications of the turbine building. Investigations to evaluate the in-situ density of backfill materials were undertaken by the licensee.
A tour of the San Onofre Unit 1 site was made in the morning. Open trenches were viewed with regard to the existing condition of back fill in the vicinity of safety-related structures. In the afternoon, a meeting was held at the offices of Woodward-Clyde, Santa Ana,.
California. Enclosure 1 is a list of attendees. At this meeting, the licensee and consultants discussed the procedures that were used to determine the extent of the backfill around safety-related struc tures and the in-situ engineering properties of the backfill.
Based on the finding of more loosely compacted soil than originally reported, the NRC staff requested that the licensee reassess and resubmit the safety analysis report for Systematic Evaluation Program.
Topic II-4.F, Settlement of Structures and Buries Equipment. The licensee stated that they would review the safety assessment report and resubmit a revised version in late December 1982 or early January 1983.
