THIRD INTERIM REPORT' Description of Deficiency-

- l A potential problem has oeen ' identified concerning the fuel oil line from -

the engine-mounted fuel transfer pump to the engine fuel oil header on the -

standby diesel generator in that excessive. engine vibration could'cause the line to break. The resulting loss of fuel oil would shut the engine down and the subsequent fbel spray. could be ignited by the exhaust system. -

These generators are supplied to TVA by' Transamerica Delaval, Inc. (TDI) of-Oakland, California. TDI informed TVA of this potential problem in their letter. dated September. 30, 1983.

Interim Progress s

TVA is still in the process of' investigating the subject-deficiency.

Corrective actions -to be taken have been identified as reported in _our-second interim report dated April 6,1984. However, further corrective actions and a scheduled date for completion of these. actions will be provided upon implementation of the TDI diesel generator Owners group program.
