-- E~ntfgy Waterford 3 Emergency Diesel Generator Fuel Oil Storage Project NRC Overview April 5, 2006 Entorgy Objectives
- Increase margin by using EDG "rated capacity" method to calculate fuel storage requirements
- Increase margin by installing significantly more on site fuel oil storage capacity (40,000 gallons)
- Fully comply with EPU commitment
- Use standard No. 2 diesel fuel oil
- Slight reduction in FOST to reduce operator burden 2
1
-Entergy EPU Commitment To improve the fuel oil storage capability and provide a larger operational band, Waterford 3 commits to a design change to the onsite fuel oil storage system that will accommodate fuel oil storage volume equivalent to the fuel oil needed to run each DG for seven days based on calculational methods described in American National Standards Institute (ANSI) Standard N195-1976, "Fuel Oil Systems for Standby Diesel Generators." The modification will be completed by December 31, 2006. Supporting TS changes will be submitted as needed to support changes.
