Dear Mr. Schnell:
SUBJECT:
CALLAWAY NUCLEAR PLANT - RESPONSE TO NRC BULLETIN 89-01, SUPPLEMENT
- 2. " FAILURE OF WESTINGHOUSE STEAM GENERATOR TUBE MECHANICAL PLUGS" (TAC NO. M81598)
On June 28, 1991, NRC Bulletin 89-01, Supplemer.t 2, was issued to all holders '
I of operating licenses or construction permits for pressurized water reactors (PWRs). The bulletin requested that actions similar to those requested in NRC Bulletin 89-01, " Failure 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 i
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 July 24, 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 Callaway and find the information and planned / accomplished actions to be acceptable. Therefore, we are closing out TAC No. M81598.
Sincerely, Original Signed By:
L. Raynard Wharton, Project Manager Project Directorate III-3 Division of Reactor Projects - III/IV/V Office of Nuclear Reactor Regulation cc: See next page
