SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) i DOCKET NO. 50-445 i
C0ATING REMOVAL FROM STATION SERVICE WATER l
SYSTEM DIPING Gentlemen:
[
TV Electric has been involved in a program to address corrosion concerns relating to the Station Service Water System (SSWS) at the Comanche Peak Steam Electric Station (CPSES).
A portion of that program involved removing the internal coating from specific sections of the SSWS piping.
The coating removal activities were discussed in Inspection Reports 50-445/88-34; 50-446/88-30 dated June 17, 1988: 50-445/88-40; 50-446/88-36 dated July 15, 1988: 50-445/88-47 and 50-446/88-42 dated September ?, 1988,
[
dnd in d managemenc meeting on September 13, 1988.
In the meeting, TV Electric discussed coating removal activities including various concerns enc ontered, both administrative and technical.
The TV Electric presentation
[
was based upon reviews which have been on-going and an engineering report which was under development.
[
During the meeting, TV Electric committed to complete and submit this l
engineering report by September 23, 1988.
Subsequent to the meeting, an NRC representative requested a chronology of the events related to the coating t
removal effort.
This chronology has been prepared and incorporated into the i
engineering report.
The engineering report is enclosed with this letter.

i TXX-88699 September 23, 1988 Page 2 of 2 As a result of this review, TV Electric has identified several actions which are being impicme'ted.
These actions inclu1e corrective actions as well as enhancement
- < assure that concerns are corrected and that similar concerns do not tur.
These actions are described in the enclosed
~ report and actions are scheduled to be comp 1"+ed on cr before December 1, 1988.
J Since TV Electric recognizes that identification of root causes and contributing J
facters can be a subjective process, there are two points that it believes
[
should be emphasized.
First, labeling one concern as a root cause and r
others as contributing factors did not lead to the latter receiving any l
less attention.
Such con: erns were carefully evaluated for po*ential generic implications, and corrective and preventive :ctions were developed i
to preclude recurrence.
Secondly, TV Electric scrutinized the corcerns i
that were identified in the entire coating removal project, from the problem characterization phase to the evaluatton of dage to the pipe.
Consequently, l
all concerns have been fully and appropriately addressed.
Very truly yours.
