Subject:
Virgil C. Summer Nuclear Station Docket No. 50/395 Operating License No. NPF-12 Steam Generator. Tube F* Application
Dear Sir:
In a letter dated May ~15,1987, South Carolina Electric & Gas Company.
subndtted the results of F* tube inspections in accordance with the requirements'of Technical Specifications, Section 4.4.5.5.d.
The inspection-results were from the third inservice eddy current examination of Virgil C.
Summer Raclear Station steam generator tubing performed during the months of March and April 1987.
A recent review of this letter and its attachments identified a typographical error on Attachment I in Row 41, Column 25 of Steam Generator "A."
The indication location in the May 15 submittal should have been TEH+9.6 instead of TEH+19.6. The error has'been corrected in the amended attachment to this letter.
As addressed in the original submittal, the following basic program was used for' each steam generator:
100 percent of rows 45 through 49 (all columns) for full length of tubing; a 4x4 matrix of the remainder of i.he tubes, full length of tubing; a sample of the peripheral tubes, full length of tubes; all row 1 & 2 to the 14th support (14C) outlet side and an inspection of all inlet tube sheet regions within the remaining balance of steam generator tubes. The examination was conducted utilizing digital multifrequency techniques, k

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 tube end (TEH) and'are in inches.- For further clarification, the code "DRI"'
indicates distorted-roll with possible indication, and "NDD" 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.
