- 1) Westinghouse Letter 0G 94 107, dated December 30, 1994, Summary of NRC/W/ Industry Meeting on Alloy 600 Steam Generator Mechanical Tube Plugs and WOG Recommendation for Utility Action Gentlemen:
In December 1994. Westinghouse notified TU Electric (Reference 1) of recent field experience with Alloy 600 thermally treated (TT) mechanical plugs that necessitated a revision to the corrosion algorithm presented in WCAP 12244, Rev. 3. " Steam Generator Tube Plug Integrity Summary Report," November 1989, for all remaining Alloy 600 TT mechanical plugs in service that had not been repaired or replaced. This report is a voluntary supplemental response to NRC Bulletin No. 89 01 Supplement 2.
In response to Reference 1. TU Electric has verified that this issue does not impact CPSES Unit i nor Unit 2 since all installed Alloy 600 TT mechanical plugs have been replaced in all steam generators. Therefore, this e.9mpletes TV Electric's actions with respect to this issue.
