SUBJECT:

Grand Gulf Nuclear Station Unit 1 Docket No. 50-416 License No. NPF-13 File 0260/15525/15526/16694.4 PRD-83/17, Interim Report, Diesel Generator Low Pressure Fuel Oil Line Failure AECM-83/0822 On December 30, 1983, Mississippi Power & Light Company notified Mr. D.

Verelli, of your of fice, of a Reportable Deficiency at the Grand Gulf Nuclear Station (CGNS). The deficiency concerns the failure of a fuel oil line immediately adjacent to a male branch tee on the Unit 1, Division I diesel generator.

MP&L has evaluated this deficiency and determined that it is reportable under the provisions of 10CFR21 for Unit 1. The investigation is continuing to determine reportability or corrective action required for Unit 2.

Details are provided in our attached Interim Report. MP&L expect s to submit the next report by April 13, 1984.

Yours truly

J. P. McGaughy, Jr. )

'Vice-President, Nuclea r 1 P.O. Box 1640

' Jackson, Mississippi 39205 This deficiency was also reported under 10CFR21 by Transamerica Delaval to the NRC in their. letter dated September 21, 1983.

I 2.. Identification of the facility ... which .. contains a deficiency

, Grand Gulf Nuclear Station (GGNS) Unit 1.

Port,Gibson, Mississippi 39150 3.. Identification of the firm ... supplying the basic component which .. .

contains a deficiency:

The low pressure - fuel. line asemblies were manufactured _ by Transamerica Delaval, Inc. , and supplied to Grand Gulf by Bechtel Power Corporation, Gaithersburg, Maryland.

4. Nature of the deficiency ... and the safety hazard which ... could be created by such a deficiency . ..:

• A. Description of the Deficiency The deficiency involves a condition on the Unit 1, Division I diesel generator where the failure of a fuel oil line immediately adjacent to a male branch tee caused a fire in the Division I

diesel generator area. During the investigation following the fire it was discovered that a required support was missing from

~

the fuel oil line.

i . The failed line was forwarded by MP&L to Middle South Services,

. Inc. , (MSS) for metallurgical evaluation. The MSS metallurgical evaluation report indicated. that the f ael oil line failure was due I to high cycle fatigue caused by a combination of vibration from

-the turbocharger and the absence of the required support on the

. fuel oil-line.

.B. - Analysis of Safety Implications The lack of the proper support on the low pressure fuel line could result in failure of the line. Since fuel is supplied via this line ~ to the engine, a failure of the line would cause the engine to be inoperable. The support was absent on both the Unit 1, Division I and II diesel generators, thus failures of the lines .

could result in both diesel generators' inability to perform their design functions in the' event- of an LOCA.
