~ Messrs. Rosenthal, Johnson & Wilber January 8, 1986 Page Two Although the cause of the occurrence is still under inves-tigation, the Board Notification states that the problem is be-lieved to be unique to the particular diesel generator which experienced the failures. The enclosed Affidavit of Edward C.

Christiansen, a Senior Design Engineer at Perry, supports this conclusion and provides information on the steps which have been taken to preclude a similar problem with the Perry diesel generators.
