| START OF DIVISION III DIESEL DUE TO GRID VOLTAGE DIP                         |
|                                                                              |
| "On 4/25/02 at 0513 while lining up to backfeed through the main power       |
| transformers in preparation for a                                            |
| Reserve Auxiliary Transformer outage, a low grid voltage condition occurred, |
| resulting in the auto start of                                               |
| the Division 3 Diesel Generator.                                             |
|                                                                              |
| "The Procedure to backfeed power from the switchyard to the plant electrical |
| buses was in progress. This                                                  |
| procedure was being used to support removing one of the offsite power        |
| sources supplied through the                                                 |
| Reserve Auxiliary Transformer (RAT) which was being removed from service for |
| maintenance. When the                                                        |
| disconnect was closed in the switchyard completing the backfeed, the Static  |
| Var Compensators (SVC) for                                                   |
| the two offsite powers sources, the RAT SVC and the Emergency Reserve        |
| Auxiliary Transformer (ERAT)                                                 |
| SVC tripped. The offsite power sources supplying the RAT and ERAT remained   |
| energized                                                                    |
|                                                                              |
| "The SVCs maintain voltage from the RAT and ERAT to the plant within a       |
| constant voltage band. Without                                               |
| the SVCs, low grid voltage may result in low 4160kv bus voltage. At the time |
| this occurred the Division 1                                                 |
| and 2 buses were being supplied from the RAT, which has three 345kv sources, |
| and the Division 3 bus was                                                   |
| being supplied from a separate 138kv source. It was the 138 kv source that   |
| experienced the degraded                                                     |
| voltage that resulted in thc Division 3 ERAT supply breaker opening (offsite |
| power source) and the                                                        |
| Division 3 Diesel Generator starting and closing in on the Division 3 bus.   |
|                                                                              |
| "Following the grid voltage transient, grid voltage returned to the          |
| pretransient level. The RAT and ERAT                                         |
| SVCs were restored to service and both offsite power sources were made       |
| operable. No damage to plant                                                 |
| equipment was observed during the initial investigation. The Division 3      |
| Diesel Generator was paralleled to                                           |
| the ERAT offsite power source and loaded. The diesel generator has been      |
| divorced from the ERAT and the                                               |
| Division 3 bus is being carried by the ERAT in the normal lineup."           |
|                                                                              |
| The NRC Resident Inspector was notified.                                     |

| TRASH BURNING FACILITY RADIATION MONITORS ALARM ON WASTE SHIPMENT
FROM       |
| GRIFFIN HOSPITAL                                                             |

| The Bridgeport RESCO trash burning facility notified the GriffinHospital     |
| that a waste shipment from the hospital set off the radiation monitors. A    |
| consultant from the hospital was dispatched to the trash facility to         |
| identify the cause of the alarm.  The consultant reviewed the wasterecords   |
| from the hospital and preliminarily determined that a radioactive diaper was |
| most probably the source of the radioactivity.                               |
|                                                                              |
| ***UPDATE S. KORZHIN to R. LAURA on 4/25/02 at 1830***                       |
|                                                                              |
| Investigation found approximately 5 or 6 diapers with patient waste that had |
| a maximum surface reading of 10 millirem per hour.  The radioactive isotope  |
| involved was iodine-131. The diapers will be transported back to the         |
| hospital where they will be stored for radioactive decay.  Also assisting    |
| the hospital contractor was the Connecticut Department of Environmental      |
| Protection.                                                                  |
