revision amended the definition of the steam generator Plugging Limit as ,

outlined in section 4.4.5.4a. The request excluded from plugging those tubes [

with defects greater than a distance 1.25 inches below the top of the tube sheet.

After discussion with members of your staff on August 28, 1986, SCE&G is submitting an updated T.S. revision package. This letter, with the updated T.S.

page attachments incorporates the previous revision requests and further information requested by your staff. The submittal supercedes the previous submittals.

l The technical basis for this revision has been previously submitted as attachments to the August 15,1986 letter.

The application fee for the review of the amendment request has been submitted previously with the August 30,1985 letter from O. W. Dixon, Jr., to Mr. H. R.

Denton.

The statements and matters set forth in this submittal are true and correct to the best of my knowledge,information and belief.
