Vogtle Electric Generating Plant-Units 1 and 2, 50-424, 50-425; Transamerica Delaval Diesel Generators Engine Fuel Control Levers Attention: Mr. James P. O'Reilly By letter dated October 2,

1984, Transamerica Delaval notified the Nuclear Regulatory Commission, Office of Inspection and Enforcement, of a potential defect in a component of the DSRV Standby Diesel Generator.

The specific potential defect identified involved the fuel control lever. These levers are held by friction generated by tightening a cap screw.

The levers are also pinned to the control shafts by using a 1/4 inch roll pin.

Apparently, Southern California Edison discovered one or more levers on one of its diesel generator engines that were not properly pinned. The Southern California Edison discovery indicated that unpinned levers and lack of proper torque on the securing cap screw could result in movement of the fuel control lever.

Plant Vogtle was identified as a potentially affected nuclear site in the October 2 letter.

For that reason, we have examined and inspected the levers on the Vogtle engines.

As a result of our inspec-tion we have determined that the Vogtle levers were properly pinned to the shafts and that torque on the securing cap screws properly maintained.

We have, therefore, concluded that the potential problem identified at Southern California Edison does not exist at the Vogtle site. We are now prepared to close this issue.

This response contains no proprietary information and may be placed in the NRC Public Document Room.
