positions in RG 1.75.

On June 2 and 3, 1987, the staff met with representatives of the licensee to discuss RG 1.75 compliance.

At these meetings, the licensee identified speci-fic areas at Rancho Seco where the positions of RG 1.75 regarding physical separation were not met.

For these areas, the license proposed to demonstrate by analysis and/or test that the installed cable / wire configurations are accep-table.

The licensee's approach for demonstrating acceptability was discussed in detail at these meetings.

At the conclusion of the meetings, the staff had agreed in principle with the licensee's approach.

It was recommended that the licensee document their approach and submit it to the NRC for review and evaluation.

On June 26, 1987, the licensee formally submitted Engineering Report ERPT-E0220, which details l

the licensee's approach for demonstrating compliance with RG 1.75, for NRC review.

The report was submitted under cover of SMUD letter, serial GCA87-212 dated June 26, 1987.
