| REDUCTION AT 0239 CST DUE TO DECREASING LEVEL IN THE CIRC. WATER INLET       |

| During the performance of a surveillance test, with a half scram signal      |
| inserted, a spurious trip signal from the other system initiated a trip of   |
| all the reactor coolant system recirculation pumps.  The operators manually  |
| scrammed the reactor per procedure, all rods fully inserted.  Heat removal   |
| is via the main condenser with main feedwater feeding the reactor.  All      |
| systems functioned as designed and the plant is proceeding to cold shutdown. |
| A trip review will be performed by the licensee.                             |

|                                                                              |

| On 01/21/00, the licensee inserted a manual scram in accordance with station |
| procedures in response to a trip of all the reactor recirculation pumps.     |
| The trip of all the pumps was due to an error in the performance of the      |
| ongoing surveillance test.                                                   |
|                                                                              |
| "During the performance of an instrument logic surveillance test on the      |
| isolation condenser actuation logic which also inserts trip signals into the |
| recirculation pump trip logic, the reactor recirculation pumps tripped.      |
| After testing the first instrument, the trip signal associated with the      |
| isolation condensers were reset; however, the recirc pump trip logic was not |
| properly reset before proceeding to the second instrument.  When a test      |
| signal was introduced on this instrument, the reactor recirculation pumps    |
| tripped as designed.  In response to the pump trip, the operators manually   |
| scrammed the reactor.  The plant is currently in cold shutdown.  A trip      |
| review has been performed.  Oyster Creek plans to take advantage of this     |
| shutdown to perform some other maintenance activities."                      |
|                                                                              |
| The original report should have read "half trip" rather than "half scram"    |
| referring to the trip logic of the reactor recirculation pumps; this was     |
| entered wrong the first time.                                                |

| MANUAL REACTOR TRIP DUE TO FEEDWATER OSCILLATIONS                            |

| The licensee had reduced power to 95% to examine the '4A' steam generator    |
| feedwater regulating valve due to feedwater oscillations.  A preliminary     |
| determination of valve internal problems versus control problems was made.   |
| The licensee was ready to continue the down power to shutdown to repair the  |
| feedwater regulating valve, when a manual trip became necessary due to the   |
| feedwater oscillations on '4A' steam generator.                              |
|                                                                              |
| All systems functioned as designed, all rods fully inserted, no secondary    |
| safety valves lifted, and the plant is stable in Mode 3.  Heat removal is    |
| via the atmospheric steam dumps, normal procedure with no tube leaks, and    |
| feedwater is via the standby feedwater system.  The plant will remain shut   |
| down until repairs to the feedwater regulating valve are complete.           |
