• N>rmal electrical alignment has one of the safeguard buses supplied by the Tertiary Transformer which supplies only safeguard loads. An undervoltage condition would not occur during a loss of of f-site power since the diesel generator is able to supply all safeguard loads and since no other in-plant loads are supplied by the Tertiary Transformer. Transferring the safeguard buses to the Tertiary Transformer while load testing the D/G is being considered as another procedural change to further ensure the reliability of emergency power. Furthermore, the load test surveillance will in the future not be per- ~-

formed when one D/G is out of service. ;_

Cause Description and Corrective Actions The first failure of D/G 1A manual speed control was caused by excessive wear to the pinion that mates to the worm shaf t in the electric speed control (syn-chronizing motor) gear housing assembly. The synchronizing motor gear housing assembly was replaced and the D/G was tested and returned to service within the time period allowed by LCO TS 3.7.b.2. As recommend 2d by the D/G vendor additional parts were added to the list of spare parts maintained at the plant to facilitate any future repairs that may become necessary. When parts were received, a new pinion was installed in the original gear housing assembly and this unit was re-installed on the governor for 1A D/G. Following the second failure of manual speed control the new pinion was found badly damaged. The apparent cause was attributed to misalignment of the neu plaion during the repair process. Another new pinion was installed in the gear housing and aligned with the vorm shaft. The D/G was returned to service for the fuel consumption test within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> and was declared fully operable upon successful completion of this test. Following the failure on 3-13-79, investigation re-vealed that a limit switc, on the 1A D/C governor was not activating properly and, therefore, was not ce-energizing the synchronizing motor before the motor output shaft reached its end-of-travel. The failure of the limit switch re-suited in damage to the pinion since it was being driven past its end of travel.

A vendor representative installed and aligned a new pinion and the limit switch was replaced and adjusted. Following operation of D/G 1A the vendor representative inspected the synchronizing motor gear housing and found no indications of abnormality. The 1A D/G was returned to service.

Existing maintenance procedures will be changed to include inspection of DIG governor internals on a frequency intended to prevent similar occurrences in the future. This is the first failure of this type at the Kewaunee Plant.
