At the conclusion of the Station Blackout (SBO) Implementation

  • Inspection, Duke personnel verbally outlined seven calculations that would be prepared or revised to complete the' documentation '

to support implementation of the requirements of the SBO Rule.

The calculations are Class 1E Battery Sizing,' Class lE Battery Voltage, SSF Battery Voltage, EDG Battery Sizing, EDG Battery ,

Voltage, SSF Diesel Loading, and SSF Diesel Voltage. The last two have now been combined into one calculation for SSF Diesel '

Loading and Voltage, resulting in six calculations to be completed. Attachment 1 documents Duke's plans for completion of the documentation'by June 30, 1994. '

1) Class 1E Battery Sizing - EPL System
2) Class 1E Battery Voltage - EPL System

. 3) SSF Battery Voltage - ETM System

4) EDG Battery Sizing - EPQ System
5) EDG Battery Voltage - EPQ System
6) SSF Diesel Loading - ETL System
7) SSF Diesel Voltage ETL System The last two have been combined into one calculation for SSF Diene 3 Loading and Voltage - ETL System, resulting in'six calculations to be completed. The recommendations and concerns detailed in the Inspection Report will be addressed in .the revisions to the calculations.
