| TECH SPEC REQUIRED SHUTDOWN - BACKLEAKAGE FROM THE S/G TO THE AUXILIARY      |
| FEEDWATER SYSTEM.                                                            |
|                                                                              |
| Check valve leakage from the # 1 Steam Generator caused a rise in            |
| temperature in the discharge piping of the "A" auxiliary feedwater pump.     |
| The maximum allowed temperature is 190 degrees F.  The maximum temperature   |
| reached was 300 degrees F.  The licensee entered Tech Spec 3.0.3 at 1209 and |
| started slowly lowering power.    Injection with the "A" AFW pump reduced    |
| the temperature in the line below the limit.  The licensee is waiting to     |
| determine if the check valve has reseated.                                   |
|                                                                              |
| The licensee notified the NRC resident inspector, the town of Waterford and  |
| the state of Connecticut.                                                    |

| TS 3.0.3 was exited at 2338 2/28/2000. The unit is returning to rated power. |
| The NRC resident inspector will be informed of this update by the licensee.  |
| Notified R1DO (Trapp).                                                       |
