- 1. Is there a breaker between the main generator and the main power transformers?
- 2. Is the 2C Diesel Generator (DG) a Class 1 E diesel?
- 3. Does the 1 C DG have the capacity to shutdown the unit under safety injection conditions?
- 4. What are the common equipment loads among the two Units?
- 5. What are the licensing basis accident loads for each of the four DGs.
- 6. Provide information on logic that prevents starting 2 pumps in the same train.
- 7. Is the 2C DG credited in the Probability Risk Assessment?
- 8. Does the sequencer perform the load shed function or do the under voltage relays perform the load shed function?
No regulatory decisions or commitments were made during the meeting. There were no members of the public that participated.
