| hours on 08/08/01 while investigating a failure of the 4A EDG ventilation |
| system. The 4A EDG was restored to operable status at 1920 hours on |
| 08/08/01. The Unit 4 SUT was taken out of service at 0800 0n 08/08/01 for |
| planned maintenance. The SUT on Unit 4 was returned to operable status at |

| RETRACTION |
| |
| The licensee is retracting the notification made on August 8, 2001, in which |
| it was reported that the Unit 4 Startup Transformer and the 4A Emergency |
| Diesel Generator (EDG) were both inoperable (NRC Event Report 38192). The |
| licensee has determined that the failure of the 4A EDG ventilation system |
| did not make the 4A EDG inoperable. Therefore, there was no time during |
| which the 4A EDG and the Unit 4 Startup Transformer were simultaneously |
| inoperable. |
| |
| The NRC Resident Inspector will be notified. Notified Reg 2 RDO(Monninger) |
