SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NOS. 50-445 AND 50-446 REQUEST FOR ADDITIONAL INFORMATION ON RESPONSE TO NRC BULLETIN 88-05 AND SUPPLEMENTS 1 AND 2 t
REF:
1)- TV Electric letter from Mr.'W. J._Cahill, Jr. to U. S. NRC dated January 11, 1989, TXX-89005
- 2) TV Electric letter from Mr. W. J. Cahill, Jr. to U. S. NRC dated March-31, 1989, TXX 89163 Gentlemen:
-TV Electric responded to NRC Bulletin 88-05, " Nonconforming Material Supplied by Piping. Supplies, Inc. (PSI) at Folsom, New Jersey and West Jersey Manufacturing = Company (WJM) at Williamstown, New Jersey" as modified by
. Supplements 1 and 2, by TXX-89005, dated. January 11, 1989 and TXX-89163, dated March-31, 1989.
In recent discussions, the NRC staft requestod additional information regarding our response to NRC Bulletin 88-05, and' Supplements 1 and 2, The
.{
'following additional information is provided in the response to that request:
=
- 1) The attached table provides the requested information for the twelve non-conforming flanges received and installed in the noted safety-related systems.
- 2) No chemical test data is available for the heat numbers representing these l
twelve low hardness flanges from the NUMARC/Bechtel data base.

- 3) TV Electric will conduct a chemical test on one flange per each of the three heat numbers represented in the attached table. The flances selected-for chemical testing may be from Unit 1 or Unit 2.
The results
.of this chemical test will be available for NRC review at CPSES site after February 5, 1990.
