Serving The Best Location in the Nation November 10, 1983 VICE PRESIDENT NUCLEAR Mr. James G. Keppler Regional Administrator, Region III Office of Inspection and Enforcement U.S. Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, Illinois 60137 RE: Perry Nuclear Power Plant Docket Nos. 50-440; 50-441 Potential Defect with Engine Mounted Fuel Oil Line/Transancrica Delaval, Inc. [RDC 84(83)]
Dear Mr. Keppler:
This letter serves as an interim report pursuant to 10CFR50.55(e) concerning a possible problem with an engine mounted fuel oil line on the diesel generator engines supplied by Transamerica Delaval, Inc. (TDI).
Mr. R. C. Knop of your office was first notified on October 11, 1983, by Mr. E. Riley of The Cleveland Electric Illuminating Company that this matter was being evaluated for applica-bility to the Perry Nuclear Power Plant (PNPP).
This report contains a description of the potential deficiency, of corrective action taken to date, and the planned date for our final report.
Description of Potential Deficiency The potential deficiency is associated with the Fuel Oil Line which runs between the engine mounted Fuel Transfer Pump to the Fuel Oil Header on the diese) generator. This problem was first identified at Grand Gulf I where the Fuel Oil Line broke shutting the engine down.
Initial information indicated that the line break at Grand Culf I resulted from excessive line vibration.
This item was reported to the NRC September 21, 1983, by Transamerica Delaval, Incorporated as a 10CFR21.
Subsequently, Perry Nuclear Power Plant was notified of this as a possible problem by Transamerica Delaval, Inc.
Corrective Action Taken to Date A review of the fuel oil line assembly attachments for each of the PNPP diesel engines supplied by TDI has been conducted by the Project Organization and representatives from TDI. Based upon this review, additional clamping devices were determined to be needed to minimize the potential vibration problem and the needed parts have been ordered. These parts will be installed prior to engine operation.

Mr. Jimea G. Kepplsr Novsnbar 10, 1983 In addition to the mounting attachments, Project Organization personnel are evaluating other recommendations proposed by TDI.
Currently we are reviewing recommended modifications in case of a Fuel Oil Line break and Project Organization maintenance activities associated with this potential vibration problem.
We are presently planning to submit our final report on this subject by January 31, 1984.
Please call if you have any questions.
