H. B. ROBINSON UNIT No. 2 LICENSE DPR-23 STEAM GENERATOR TUBE IEAKAGE INVESTIGATION

Dear Mr. Skovholt:

By copy of this letter, we are submitting a topical report prepared by Westinghouse Electric Corporation on behalf of Carolina Power & Light, entitled "H. B. Robinson Steam Generator Tube Leakage Investigation". This ~y

! report outlines the operating history of the steam generators prior to the ,

! discovery of primary-secondary tube leaks in May, 1972 and the subsequent l

investigations and tests of the steam generators and tubes. Also included are conclusions as to the probable cause of the tube failures and the corrective measures taken to prevent recurrence of tube leakage. The infor-mation contained in the report supplements earlier information provided by Carolina Power & Light Company as part of the Routine Operating Report No. 4, q

which was submitted on November 30, 1972 and our letter of October 27, 1972 on integrity of steam generators under accident conditions. - ]'

a l Very truly yours,
