W. G. Counsil' Letter TXX-88817 to NRC dated November 30, 1988 Gentlemen:

Reference 1 provided TV Electric's initial response to six action' items in the subject NRC Bulletia.

In that letter we indicated our evaluation of the J

identified safety-related systems and pumps-for Unit 1 and Common would be completed by December 1, 1988. Reference 3 revised the schedule for-completion.of this evaluation to February 13, 1989.

Subsequent to the submittal of reference 1, the Centrifugal Charging Pumps in the Chemical and Volume Control System (CVCS) have also been identified in reference 2 a: having a' configuration that does not preclude pump-to-pump interaction during m1niflow operation and could potentially result in deadheading one or more of the pumps.

As a result.of this additional i

configuration concern, the schedule for completion of the evaluations required by NRC Bulletin 88-04 is being revised to April 28, 1989 for Unit 1 and Common.

The schedule for Unit 2 evaluation completion is' unchanged, a
