NRC Bulletin No. 89-01, Supplement 2, Failure of Westinghouse Steam Generator Tube Mechanical Plugs
Dear Sirs:
Subj ect:
Palo Verde Nuclear Generating Station (PVNGS)
Units 1, 2,
and 3
NRC Bulletin No. 89-01, Supplement 2, Fai.lure of Westinghouse Steam Generator Tube Mechanical Plugs File:
91-055-026 NRC Bulletin 89-01 requested addressees to 1) verify that information contained in Table 2 of Reference A for their plants is correct for plugs fabricated from group 2 heats, and 2) repair or replace the plugs as required by the schedule stated in the Bulletin.
As stated in Reference C, Arizona Public Service Company (APS) identified that 95 Westinghouse Inconel 600 steam generator tube plugs had been installed in Unit 2.
These 95 Westinghouse Inconel 600 steam generator tube plugs have been replaced with Inconel 690 mechanical tube plugs during the Unit 2, Cycle 3
refueling outage.
Since APS has replaced the Inconel 600 steam generator tube plugs, verification of the information contained in Table 2 of Reference A was not necessary and actions taken to replace the plugs are completed.
PVNGS does not have any Inconel 600 steam generator tube plugs installed in the other units.
