Dear Mr. Denton:
On September 30, 1983 representatives from Duke Power Company and the NRC Staff met at the NRC's offices in Bethesda, Maryland to discuss License Condition 18, Internal Corrosion Protection for Fuel Oil Storage Tanks.
Summaries of the meeting were documented in my letter of November 11,1983 and in the Staff's memo dated November 25, 1983.
It has been Duke's position that appropriate design and operating features have been provided to minimize internal corrosion of the buried fuel oil tanks and that extensive experience has identified no problems with uncoated tanks.
In order to provide the NRC Staff with additional justification for not internally coating the fuel oil storage tanks at Catawba, a survey was conducted to assess the experience of other Duke facilities and local industry.
Duke Experience Buried fuel oil storage tanks at Duke's Cliffside and Allen Steam Stations have been inspected. The Cliffside-5 lower fuel oil tank was inspected in April 1977. There was no sign of rust within the 50,000 gallon tank after six years of service. The two fuel oil storage tanks at the Allen Steam Station were cleaned during July 1964 following approximately seven years of service. These inspections revealed the interior surfaces to be in excellent condition with no evidence of rusting or pitting except in the access standpipe where light rusting nad occurred.
Local Industry A recent survey was conducted of local industries that owned large buried fuel oil storage tanks. Of the ten industries contacted, none had internally coated tanks and none had experienced problems with internal corrosion of the tanks. A list of the industries contacted is attached.

Mr. Harold R. Denton, Director May 31,1984 Page 2 Based on the previous submittals, meetings,and discussions with other owners of: buried fuel oil storage tanks, it is concluded that internal corrosion of buried fuel oil storage tanks is not a safety-significant problem.
It is therefore requested that this item be closed in a future supplement to the Catawba SER.
Very truly yours, b-l8W Hal B. Tucker ROS/php Attachment cc: Mr. James P. O'Reilly, Regional Administrator U. S. Nuclear Regulatory Commission Region II 101 Marietta Street, NW, Suite 2900 Atlanta, Georgia 30303 NRC Resident Inspector Catawba Nuclear Station Mr. Robert Guild, Esq.
