1. IX04w ork has been rcinoved froi the outage scope per OCC.

2. Sump 'B' Screens will be removed 5/1204. This SD safety assessment assumes this condition exists.

3. Only one train ofRHR is available during the IT-530D testing.

4. Will commence using 1.3 factor for time to boil when core reload is complete.
