Gentlemen:

On July 29, 1987, we verbally notified your Mr. H. S. Phillips of a deficiency involving backup protection for the 480V containment electrical penetrations, which we deemed to be reportable in our letter logged TXX-6710 dated September 2, 1987. Our final report was logged TXX-88278 dated March 10, 1988.

This is a supplemental report to revise the schedule for completion of corrective actions to resolve the deficiency.

The estimated corrpletion date for Unit I corrective actions (described in TXX-88072) has been revised to July 15, 1988, in support of hot functional testing. The Unit 2 corrective action completion schedule date has not changed.

Very truly yours, W. G. Counsil
