R. H. Engelken, Director Office of Inspection and Enforcement Region V Suite 202, Walnut Creek Plaza 1990 North California Boulevard Walnut Creek, California 94596 Gentlemen:

Subject:

Docket No. 50-206 IE Bulletin 80-04, Analysis of a PWR Main Steam Line Break With Continued Feedwater Addition San Onofre Nuclear Generating Station Unit 1 By letter dated May 19, 1980 we advised you that we would complete our review and provide our response to Item 2 of IE Bulletin 80-04 by July 1, 1980.

The purpose of this letter is to reschedule the submittal of our response to Item 2 of IE Bulletin 80-04.

As indicated in our letter of May 19, 1980 as part of our review, Westinghouse provided data which is generic in nature.

Additional time was needed to review the applicability of this information relative to San Onofre Unit 1. In the course of our review, it was deemed prudent to perform a partial reanalysis of the MSLB core response to confirm the applicability of the generic conclusion to San Onofre Unit 1. This analysis has been completed and is currently being transmitted to us.

Following completion of our review of the results and conclusion of this reanalysis, we will provide our response to Item 2 of IE Bulletin 80-04. We estimate that our review will be completed and response will be submitted by August 1, 1980.
