| 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  |

| ****RETRACTION ON 5/17/02 AT 13:10 FROM R. Robbins to R. Laura****           |
|                                                                              |
| "ENS Event Notification #38819 was reported at 1205 CST on April 1, 2002.    |
| This event was reported in accordance with 10 CFR 50.72(b)(3)(ii)(B) for     |
| identification of an unanalyzed condition that had the potential to          |
| significantly degrade plant safety. The condition involved postulated        |
| Appendix R fire scenarios for which the safe shutdown analyses assumes that  |
| the normal motive force for charging pump control (instrument air) is        |
| unavailable due to fire-induced damage. Certain Appendix R fire scenarios    |
| require the availability of a single charging pump, operable at greater than |
| minimum pump capacity, in order to meet the Appendix R performance goal of   |
| maintaining adequate RCS inventory control without loss of pressurizer       |
| level. An installed back-up nitrogen supply is credited with maintaining the |
| ability to control charging pump flow for the duration of the 72 hour        |
| Appendix R coping period. The unanalyzed condition identified in this        |
| notification was that the installed back-up nitrogen supply, based on a      |
| conservative calculation, would have adequate capacity to provide the motive |
| force for the Single Charging pump control function for only 8 hours. After  |
| that time, the variable speed charging pump would run back to minimum speed, |
| which equates to a pumping capacity of approximately 18 gpm.                 |
|                                                                              |
| "We have subsequently completed an engineering evaluation to estimate the    |
| transient behavior of the RCS in the event of these Appendix R fire          |
| scenarios assuming only 8 hours of Charging pump speed control is available. |
| This evaluation was based on conservative assumptions regarding reactor      |
| coolant pump seal leakage and unavailability of normal cooling and safety    |
| systems. This evaluation provided estimates of key RCS transient parameters  |
| based on engineering analysis and predicts that upon reducing the available  |
| charging pump flow to the pump minimum, pressurizer pressure and level will  |
| no longer be maintained. Although RCS sub-cooling is lost and some voiding   |
| in the RCS occurs, the core remains covered during the entire 72 hour        |
| Appendix R coping period and core cooling is maintained throughout the       |
| transient.                                                                   |
|                                                                              |
| "We have therefore concluded that this previously unanalyzed Appendix R      |
| scenario would not have resulted in a condition that would have              |
| significantly degraded plant safety. Therefore, this condition is not        |
| reportable under 10 CFR 50.72 and we are hereby retracting this event        |
| notification.                                                                |
|                                                                              |
| "Until corrective actions are completed to ensure that the Appendix R safe   |
| shutdown performance goal to maintain reactor coolant inventory control      |
| within the level indication in the pressurizer can be satisfied, appropriate |
| fire rounds will continue."                                                  |
|                                                                              |

| While using a Cordis delivery system to insert a ribbon containing Ir-192    |
| seeds into a patient, the ribbon came out into the hands of the Medical      |
| Physicist. The screw and cap of the Cordis delivery system had been loosened |
| and the ribbon containing the Ir-192 seeds was supposed to be pushed into    |
| patient via a catheter but somehow the ribbon containing the Ir-192 seeds    |
| ended up in the hand of the Medical Physicist.   George Washington Hospital  |
| Radiation Safety Officer preliminarily estimated the minimum exposure to the |
| Medical Physicist hand was 63 roentgens.  The Medical Physicist walked 5 or  |
| 6 feet into another room where the Radiation Oncologist was located and      |
| dropped the ribbon to the floor. The Radiation Oncologist, wearing gloves,   |
| picked the ribbon up and placed it in a safe location.  The Radiation Safety |
| Officer for George Washington Hospital said that the Radiation Oncologist    |
| received a dose to his hand while carrying the ribbon.   An estimated dose   |
| calculation to Radiation Oncologist hands, etc., had not been made at the    |
| time of the notification.                                                    |

| AUTOMATIC REACTOR SCRAM DUE TO A TURBINE TRIP FOR UNKNOWN REASONS       
    |
|                                                                              |
| The following text is a portion of a facsimile received from the licensee:   |
|                                                                              |
| "[A] Unit-1 reactor scram occurred at 0054 hours on May 19, 2002.  The       |
| reactor scram occurred as a result of a main turbine trip.  The cause of the |
| turbine trip is under investigation.  All systems actuated as designed.  The |
| unit is being maintained in Hot Shutdown at normal [reactor pressure vessel] |
| level.  This report is being made pursuant to [10 CFR] 50.72(b)(2)(iv)(B)    |
| due to actuation of the reactor protection system (RPS).  No [safety relief  |
| valves] lifted, and currently [one] reactor recirculation pump has been      |
| restarted[.  The] scram has been reset."                                     |
|                                                                              |
| The licensee stated that reactor vessel level control is currently being     |
| maintained via normal condensate and feedwater.  The main steam isolation    |
| valves are open, the condenser is available as a heat sink, and reactor      |
| vessel pressure control is being maintained via normal electrohydraulic      |
| control pressure control.  Containment parameters are normal.  The licensee  |
| also stated that the all control rods fully inserted, that there were no     |
| engineered safety feature actuations or emergency core cooling system        |
| injections, and that none were required.  There was nothing unusual or not   |
| understood with the exception of the cause of the turbine trip.              |
|                                                                              |
| Prior to this event, the unit had been operating at reduced power to         |
| facilitate the performance of turbine stop valve testing.  The licensee      |
| stated that a combined intermediate valve (CIV) was being stroked at the     |
| time of the turbine trip/reactor scram but that stroking of the CIV is       |
| currently believed to be unrelated to the turbine trip.  At this time, the   |
| licensee believes that the cause of the turbine trip may have been related   |
| to the thrust bearing wear detector.  However, the final root cause of the   |
| turbine trip remains under investigation.                                    |
|                                                                              |
| The licensee notified the NRC resident inspector, applicable State and local |
| agencies (including Montgomery, Chester, and Berks Counties), and the        |
| Pennsylvania Emergency Management Agency.                                    |

| MANUAL REACTOR TRIP DUE TO A CONTROL ROD SYSTEM URGENT FAILURE ALARM
DURING  |
| LOW POWER PHYSICS TESTING                                                    |
|                                                                              |
| While in Mode 2 (Startup) with reactor power at 10E-6 in the intermediate    |
| range as part of a refueling outage, Unit 2 was manually tripped at 0447 EDT |
| on 05/19/02.  During the performance of low power physics testing, the unit  |
| experienced a control rod system urgent failure alarm.  Operators were       |
| inserting  Shutdown Bank 'B,' and the Shutdown Bank 'B' Group 2 step counter |
| failed to step.  Rod movement was stopped.  After performance of an          |
| evaluation, operators noticed that reactivity was increasing slightly.       |
| Operators then attempted to insert Control Bank 'D,' and the Control Bank    |
| 'D' Group 2 step counter also failed to step.  After evaluating rod control  |
| problems, the reactor was manually tripped.                                  |
|                                                                              |
| All control rods fully inserted as a result of the manual reactor trip, and  |
| all systems functioned as required.  There were no engineered safety feature |
| actuations or emergency core cooling system injections, and none were        |
| required.  The licensee currently suspects that there may be a blown fuse in |
| the rod control cabinet.  The investigation is currently underway.           |
|                                                                              |
| The unit is currently stable in Mode 3 (Hot Standby).  Normal charging and   |
| makeup, pressurizer heaters and sprays, and the reactor coolant pumps are    |
| being utilized for primary system inventory, pressure, and transport         |
| control.  Main feedwater is supplying water to the steam generators, and     |
| secondary steam is being dumped to the condenser.  Containment parameters    |
| are also normal.                                                             |
|                                                                              |

| On May 19, 2002, during the Unit 1 eleventh refueling outage, analysis of    |
| eddy current data on steam generator (SG) 1-2 indicated that greater than    |
| one percent of the total tubes inspected on SG 1-2 were defective.           |
| Thirty-six (36) defective tubes in SG 1-2 were detected and are being        |
| plugged.  Most of the pluggable indications are due to outside diameter      |
| stress corrosion cracking at the tube support plate intersections.  Review   |
| of the eddy current inspections are complete.  Results of the SG tube        |
| inspection fall into Category C-3, which requires a 4-hour non-emergency     |
| report in accordance with Technical Specification Table 5.5.9-2 and 10 CFR   |
| 50.72(b)(3)(ii) an 8-hour requirement.                                       |
