March 20, 1992 Docket Nos. 50-269, 50-270 and 50-287 Mr. J. W. Hampton Vice President, Oconee Site Duke Power Company P. 0. Box 1439 Seneca, South Carolina 29679

SUBJECT:

RESPONSE TO NRC BULLETIN 89-01, SUPPLEMENT 2, "FAILURE OF WESTINGHOUSE STEAM GENERATOR TUBE MECHANICAL PLUGS" -

OCONEE UNITS 1, 2, AND 3 (TACS M81639/M81640/M81641)

On June 28, 1991, NRC Bulletin 89-01, Supplement 2, was issued to all holders of operating licenses.or construction permits for pressurized water reactors (PWRs).

The supplement requested that actions similar to those requested in NRC Bulletin 89-01, "Fail ure of Westinghouse Steam Generator Tube Mechanical Plugs," be extended to include all Westinghouse mechanical plugs fabricated from thermally treated Inconel 600.

These actions were necessary to ensure that these plugs would continue to provide adequate assurance for reactor coolant system (RCS) pressure boundary integrity under normal operating, transient, and postulated accident conditions.

By letter dated August 9, 1991, you responded to Bulletin 89-01, Supplement 2, by providing the information addressed in the Actions Requested portion of that document. We have reviewed your response for Oconee, Units 1, 2, and 3 and find the informa tion and planned actions to be acceptable. Therefore, we are closing TAC Nos. M81639, M81640, and M81641.
