g,g ,g Page3of$g$

These draft Technical Specification pages provide limits for -

energizing all Unit 2 related diesels. The 24 second limit for diesel 2C is based on the following:

1. I second delay for intermediate relay actuation and breaker (DG-13) -

trip.

2. Up to 1 second delay for closing of the output breaker DJ06.

3. 20 second time delay for bus 2J + 2 second tolerance for time relay ,

actuation.
