| Title | No Documented Plan In Place To Receive Additional Fuel Oil During Maximum Probable Flood Condition |
| Event Description | On September 19, 2013, a potential unanalyzed condition was identified. The current licensing basis requires a 14 day supply of fuel oil. Preliminary calculations show that there is sufficient tank volume for the duration of design basis maximum probable flood condition. However, during maximum flood condition there is currently no documented plan in place to receive additional fuel oil to maintain Unit 1 and Unit 2 Emergency Diesel Generators operable and running to supply emergency power to essential loads for the duration of the effects of a design basis maximum probable flood condition. These effects, such as flooded roads, may exceed 14 days. This is not an immediate safety concern because additional fuel oil can be added to the fuel oil storage tanks for imminent flood conditions.
