| NITROGEN BACKUP SYSTEM FOR CHARGING PUMP SPEED CONTROL FOUND NOT TO

| APPENDIX R  FIRE ASSUMPTION.                                                 |
|                                                                              |
| At 0917 CT on 04/01/02, it was determined that a condition identified on     |
| 03/28/02 potentially represents a significant degradation of plant safety    |
| during response to an Appendix R event. The Appendix R credited nitrogen     |
| backup system for charging pump speed control is unable to satisfy its       |
| design function of controlling Charging System flow to the Reactor Coolant   |
| System (RCS) for the time required to place the plant in Mode 5 (Cold        |
| Shutdown).  During an Appendix R fire it is assumed that the normal motive   |
| force (instrument air) for charging control is unavailable and an installed  |
| backup is credited.  This installed nitrogen system allows inventory control |
| while in Mode 3 (Hot Standby) and is used to control RCS inventory and       |
| pressure while the RCS is cooled down and depressurized from Mode 3 (Hot     |
| Standby) to Mode 5 (Cold Shutdown).  A nitrogen bottle 12-pack is calculated |
| to last for approximately 8 hours. PBNP has 1 spare approved nitrogen pack   |
| on site - - it has been calculated that up to 15 spares would be required    |
| for 72 hours of charging pump operation.  Mode 5 (Cold Shutdown) is expected |
| to be reached in 30 hours but may be as long as 72 hours.                    |
|                                                                              |
| This issue places the plant in an unanalyzed condition that has the          |
| potential to significantly degrade plant safety (RCS Inventory Control) and  |
| thus is reportable.                                                          |
|                                                                              |
| The associated charging pumps have been declared out of service for Appendix |
| R use and compensatory actions undertaken that establish appropriate fire    |
| rounds.  Fire rounds will be continued until the condition is corrected or a |
| suitable evaluation is completed.                                            |
|                                                                              |

| At 1436 CT on 04/01/02,  during a low flow start surveillance test the "A"   |
| division of the Control Room Ventilation System failed to autostart.  At the |
| time, the "B" division was disabled in order to perform the test.  Thus, the |
| Control Room Ventilation System accident mitigation function was lost.       |
| Division "B"  Control Room Ventilation was restored to operability at 1600   |
| hours CT.  The "A" division is operating with the control switch in the run  |
| mode.  The cause of the failure to Autostart is under investigation.         |
|                                                                              |
| The NRC Resident Inspection will be notified of this event by the licensee.  |

| Qualified visual inspection of the Unit 1 reactor vessel head Control Rod    |
| Drive Mechanism head penetrations found two penetrations with very slight    |
| boron accumulations.  Ultrasonic testing of these penetrations has           |
| determined that one nozzle (No. 7, near the center of the reactor vessel     |
| head) has a potential reactor coolant system leak path.  Any reactor coolant |
| system leakage from penetration No. 7 would have been so small it would be   |
| below the threshold of measurability by the reactor coolant system leakage   |
| measurement processes.  The leaking nozzle will be repaired prior to restart |
| from the present refueling outage.                                           |

| The licensee declared an unusual event at 0029 EST due to a broken hose reel |
| on the turbine building fire suppression CO2 system during work activities.  |
| The turbine building, reactor building, radioactive waste building, and      |
| control building were evacuated. The control room was not evacuated. The     |
| broken hose reel was isolated to terminate the release of CO2. No personnel  |
| injuries were identified as a result of the event.                           |
