| Unit 4 Startup Transformer (SUT) and 4A EDG were both inoperable for 3       |
| hours, 40 minutes on 08/08/01.  This was discovered after the fact at 1900   |
| 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   |
| 1140 hours on 08/08/01.                                                      |

| 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)  |
