| NITROGEN BACKUP SYSTEM FOR CHARGING PUMP SPEED CONTROL FOUND NOT TO
SATISFY |
| 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. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| DURING SURVEILLANCE TEST "A" DIVISION OF CONTROL ROOM VENTILATION
SYSTEM |
| FAILED TO AUTOSTART ON A LOW FLOW SIGNAL. |
| |
| |
| 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. |

| CONTROL ROD DRIVE MECHANISM NOZZLE NO. 7 PENETRATION FOUND TO HAVE A
SMALL |
| LEAK PATH. |
| |
| 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 NRC Resident Inspector will be notified by the licensee of this event. |
