ITAAC Statement

Desion Commitment

3.c) The fuel oil flow rate to the day tank of each standby diesel generator provides for continuous operation of the associated diesel generator.

Inspections/Tests/Analvses

Testing will be performed to determine the flow rate.

Acceptance Criteria

The flow rate delivered to each day tank is 8 gpm or greater.

ITAAC Determination Basis

Testing was performed in accordance with Unit 3 preoperational test procedure listed in Reference 1 to verify that the fuel oil flow rate to the day tank of each standby diesel generator provides for continuous operation of the associated diesel generator and that the testing performed verifies the flow rate delivered to each day tank was 8 gallons per minute (gpm) or greater.

Initial conditions were established with Onsite Diesel Generator A Package (ZOS-MS-05A) running with a load applied and temporary flow instruments installed to measure fuel oil flow.

Manual fill of the fuel oil day tank was initiated and flow rate readings were recorded. This testing was repeated for Onsite Diesel Generator B Package.

The results of the testing showed that the fuel oil delivery rate to Unit 3 Onsite Diesel Generator A Package was 41 gpm and 47 gpm for Unit 3 Onsite Diesel Generator B Package. This verifies the flow rate delivered to each day tank is 8 gpm or greater.

Reference 1 is available for NRC inspection as part of Unit 3 ITAAC Completion Package (Reference 2).
