Dear Mr. Seyfrit:

South Texas Project Units 1&2  :

Docket Nos. STN 50-498, STN 50-499 l Interim Report on Material Control of ASTM A-325 Structural Steel Bolts On June 17, 1980, pursuant to 10CFR50.55(e), Houston Lighting & Power Comphny notified your office of a potentially reportable deficiency concerning material control of ASTM A-325 structural steel bolts. Improper segregation and identification of Category I and non-Categcry I ASTM A-325 structural steel bolts in the field resulted in bolts procured under a non-Category I specification being used for Category I applications. This condition has been documented in Nonconformance Report S-C4377.

The inadequate material control concern was first identified during an investigation of an apparent premature inventory shortage of Category I structural steel bolts. This revealed the misapplication of non-Category I bolts. However, most of these bolts were supplied with certified material test reports (CMTR) which would allow the material traceability necessary for Category I application.

The following actions will be taken in order to resolve this potentially reportable deficiency:

1) Release of structural steel bolts for Category I applications has been halted under Stop Work #S-22 until full material traceability is established.

2) Documentation for installed bolts in Category I applications is being .

identified and located. l A

3) Material control methods and procedures are being evaluated for neces-sary modifications and improvements.

4). Documentation and Quality requirements contained in Category I Structural Steel and Miscellaneous Steel specifications are being reassessed to determine the adequacy of the bolts installed.

Sufficient information is not currently available to determine if this is a reportable deficiency under 10CFR50.55(e). However, at this time there is no indication that the installed bolts pose a potential safety hazard. An update to the status of this concern will be submitted to your office by August 27, 1980.

Should there be any questions, please contact Mr. S. S. Rodgers at (713) 676-7953.

Very truly yours,
