SUBJECT:

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)

DOCKET NO. 50-446 UNIT 2 ENHANCEMENTS Gentlemen:

Attachment A to'TU Electric's lett'er to the NRC dated April 14, 1988 (Reference 1) provided information concerning TU Electric's program for the completion of CPSES Unit 2.

The purpose of this letter is to document additional information regarding such program provided to the NRC at the public meetings on May 9 and 11, 1989.

We described at the meeting enhancements in the approaches utilized for Unit 1 that are under consideration for implementation in the completion of Unit 2 in the areas of:

(1).

Field Engineering, (2)

Specifications and procedures, (3)

Production drawings and design changes.

(4)

Design and hardware validation, and (5)

Training.

The proposed enhancements, based on experience gained in the completion of Unit 1, will enhance or maintain our emphasis on quality and represent improved engineering and construction processes. They are summarized in the slides presented at the meetings, copies of which are enclosed.

We are finalizing the procedures, specifications and other documents needed to implement these enhancements. All of these documents will be available at the site for your review at your convenience.

TXX-89271 May 19, 1989 Page 2 of 2 As you know, a number of engineering, construction, and inspection activities relating to Unit 2 structures, systems and components are being performed under the procedures and practices applied to Unit 1.

As the enhancements described at the meetings are finalized, we will consider applying them to these activities or to new activities for Unit 2.

All of the described enhancements have been discussed with CASE.

Under a conservative interpretation of the Joint Stipulation, one of the enhancements (the use of the advance design change drawing process) may require advance notification to CASE pursuant to Section A.3.

This letter serves as such notification, if required, and this enhancement will not be implemented until 21 days from the date of this letter.

CASE will also be given the opportunity to review the implementing documents described above, as they become available.

It is our understanding that the approval of the NRC is not required with respect to any of these enhancements.

We would, of course, appreciate any comments or suggestions that the NRC or CASE may have.

Please let us know if you would like any additional information.

Sincerely.

William J. Cahill, Jr.
