Steam Generator Tube F* Application
Dear Mr. Denton:
The third inservice eddy current examination of Virgil C. Super Nuclear j
Station steam generator tubinct was performed during the montts of March and l
April 1987. This letter and dts attachments provide the results of inspections of F* tubes and is submitted in accordance with the requirements of Technical Specifications Section 4.4.5.5.d.
l The following basic program was used for each steam generator:
100 percent i
of rows 45 through 49 (all columns) for full length of tubincl; a 4"4 matrix i
of the remainder of the tubes, full length of tubing; a samp'e of the peripheral tubes, full length of tubes; all row 1 & 2 to the 14th support i
(14C) outlet side and an inspection of all inlet tube sheet regions within the remaining balance of steam generator tubes.
The examination was conducted ut'lizing digital multifrequency techniques.
The attachments provide the identification, by row and column, of each tube left in service for which F* was applied. All measurements are made from the tubeend(TEH)andareininches. For further clarification, the code "0RI" indicates distorted roll with possible indication and "N00" indicates no detectable discontinuity, "% TW" indicates % through wall, and "F* location" is the highest point above the tube end at which the F* criteria can be applied in accordance with Technical Specifications Section 4.4.5.4.
If you should have any questions, please advise.
