| PLANT ENTERED 72 HOUR LCO ACTION STATEMENT WHEN DIVISION III DIESEL          |
| GENERATOR WAS DECLARED INOPERABLE                                            |

| During performance of Fire Protection Surveillance 9337.81 (performs a       |
| functional check of the Division III Diesel Generator (DG) Carbon Dioxide    |
| (CO2) system operation), the Division III DG ventilation system tripped      |
| during restoration.  Electrical Maintenance personnel were performing a      |
| functional check of the Division III DG room thermal detectors when the      |
| panel reset push button was depressed.  The anticipated resets did not occur |
| and the decision was made to restore the system to a safe condition.  During |
| restoration, a sticking relay prevented restoration of the Division III DG   |
| ventilation system.  The relay has been reset and the ventilation system     |
| restored.                                                                    |

| Division III DG was declared INOPERABLE at 1747 and the plant entered LCO    |
| 3.8.1.                                                                       |
| Action B.1- Perform 9082.01 within 1 hour and every 8 hours thereafter.      |
| Action B.2- Declare required features supported by Division Ill DG inop when |
| the redundant required features are inop, within 4 hours.                    |
| Action B.3.1- Determine Operable DG are not inop due to common cause failure |
| within 24 hours - This action -completed.                                    |
| Action B.4- Restore Div 3 DG to Operable within 72 hrs.                      |
| Division Ill DG was declared OPERABLE at 1813 and the LCO was exited.        |
|                                                                              |

| The time the diesel became inoperable was 1420 but it was not declared       |
| inoperable until 1747.   This event is being reported pursuant to 10CFR50.72 |
| (b)(2)(iii)(D) as a condition that alone could have prevented the            |
| fulfillment of the High Pressure Core Spray (HPCS) system, a single-train    |
| safety system needed to mitigate the consequences of an accident, since the  |
| Div. 3 DG is an essential support system for the HPCS system needed to       |
| mitigate a small break LOCA concurrent with a loss of offsite power.         |
|                                                                              |

| 1E41-F122, Post Accident Sampling System Inboard PCIV, failed closed between |

| approximately 1145 following completion of channel A performance test        |
| (section 7.2). After returning from lunch break, operators observed          |
| 1E41-F122 closed and could not be reopened with control switch.              |

| Unit 2 was operating at 100% power.  The Reactor Core Isolation Cooling      |
| System was removed from service for scheduled maintenance.  Following valve  |
| packing adjustment, the Reactor Core Isolation Cooling system steam supply   |
| outboard isolation valve was opened per approved procedure.  Approximately   |
| 10 seconds after the Reactor Core Isolation Cooling system steam inboard     |
| isolation bypass valve was throttled open for warming. "Division 2 Reactor   |
| Core isolation Cooling system steam line DP hi" and "Reactor Core Isolation  |
| Cooling system Steam Line/Turbine isolation" alarms were received.  The      |
| Reactor Core Isolation Cooling system steam inboard isolation bypass valve   |
| automatically closed due to an isolation signal.  The Reactor Core Isolation |
| Cooling system remains isolated by the inboard isolation valves.  The cause  |
| of the isolation signal is unknown at this time.  An investigation is in     |
| progress to determine the cause of the isolation and initiate actions to     |
| restore the Reactor Core Isolation Cooling system to an operable and         |
| available status and exit the LCO action statement.                          |

| The licensee declared an unusual event at 1510 because of a fire in          |
| containment that lasted more than 15 minutes.  A fire was reported at 1440   |
| in a tarp that was being used in containment.  The tarp is believed to have  |
| been ignited by some cutting or grinding going on in the vicinity.   The     |
| licensee called for assistance from the local fire department, but they      |
| extinguished the fire before the fire company could assist.  The fire was    |
| reported out at 1509.  The unusual event was terminated at 1615.             |
|                                                                              |
| The reactor is defueled with all fuel having been moved to the spent fuel    |
| pool.  No radioactivity was released.                                        |

| At about 1132 CDT a fire was reported in the unit auxiliary transformer,     |
| alarms were received in the control room with a unit trip, all rods fully    |
| inserted.  The on-site fire brigade and the off-site fire department were    |
| called to respond.  The fire was extinguished by installed fire suppression  |
| equipment and declared out at 1143 CDT.  The fire is being investigated by   |
| fire protection personnel.  The off-site fire department was released.       |
|                                                                              |
| The plant is stable in Hot Standby at normal temperature and pressure.  Heat |
| removal is via the main condensers with steam generator level being          |
| maintained by auxiliary feedwater.                                           |
|                                                                              |
| The auxiliary feedwater system, both turbine and motor driven, started       |
| automatically on low steam generator level as expected with this event.  All |
| safety equipment performed as designed.                                      |
|                                                                              |
| Concurrent with the reactor trip, the 'C' and 'D' reactor coolant pumps      |
| tripped along with other loads due to one (PA02) of the two non-vital busses |
| not automatically transferring as expected to off-site power.  The bus is    |
| presently energized by off-site power and the 'D' reactor coolant pump was   |
| restarted.  The actual cause of the problem is being investigating.          |
|                                                                              |
| One of the reactor coolant system power operated relief valve opened and     |
| closed one time due the transient of the 'D' reactor coolant pump trip and   |
| subsequent loss of pressurizer spray.                                        |

| "2B" AUXILIARY FEEDWATER PUMP RAN 2 HOURS AND 55 MINUTES BEFORE IT WAS       |
| DISCOVERED THAT IT WAS OPERATING. STEAM GENERATORS WERE ISOLATED FROM THE    |
| AFW SYSTEM.                                                                  |
|                                                                              |
| At 0200 ET the "B" Train of the Solid State Protection System (SSPS) was     |
| deenergized for part of their refueling outage maintenance.  When the SSPS   |
| was deenergized the blocks for the Main Feedwater Pump blocks clear which    |
| gave an automatic start signal to the "2B" AFW pump.   The on shift reactor  |
| operator did not notice that the "2B" AFW pump run light was on until 0455   |
| ET due to refueling outage maintenance activities in Control Room.  "2B" AFW |
| pump recirculated water to the Upper Surge Tank since the Steam Generators   |
| were isolated.  NO damage occurred to the AFW pump.  The licensee is         |
| investigating this event.                                                    |
|                                                                              |
| The NRC Resident Inspector will be notified  of this event.                  |
