| The Licensee reported the loss of five 0.355 microcurie, I-125 brachytherapy |
| seeds.  The seeds were model # IAI-125A and they were inventoried upon       |
| receipt from the manufacturer, Iso-Aid.  The seeds were being washed prior   |
| to sterilization (this is a deviation from procedure) and the licensee       |
| believes they were washed down the drain to the public sewer system.  The    |
| Licensee reports that surveys do not indicate that they are in the sink or   |
| trap.                                                                        |

|                                                                              |
| "On 1/17/2003 at 1130 hours, the Beaver Valley Power Station received        |
| notification that an operator found raw sewage running from the Unit 2       |
| Sewage Treatment Plant through a slightly open connection and immediately    |
| closed the isolation valve, stopping the flow.                               |
|                                                                              |
| "Assessment by the Beaver Valley response determined that a sewage removal   |
| vendor had previously attempted to pump sludge from a plant sewage system,   |
| but nothing came out.  He then apparently only partially closed the          |
| isolation valve and left the site.  Subsequently, sewage began to flow out.  |
| Approximately 750 gallons of sewage was released down a storm sewer [drain]. |
| An unknown quantity of sewage entered the Ohio River via Peggs Run.          |
| Approximately 50 gallons of sewage remaining on the surface at the local     |
| location is being cleaned up.                                                |
|                                                                              |

| The following information was obtained from the licensee via facsimile:      |
|                                                                              |
| "At 11:40 [EST] on January 17, 2003, during surveillance testing of the 'B'  |
| train Reactor Trip Breaker (RTB), the breaker  spuriously opened.  This      |
| caused the RTB to fail its surveillance test and be declared inoperable.     |
| The facility Technical Specifications (TS), LCO 3.3.1 (Reactor Trip System   |
| Instrumentation), Action 8 of Table 3.3-1 requires 6 hours to Mode 3, Hot    |
| Standby.  Rework activities were begun but the station commenced a power     |
| decrease at 14:43 [EST] to comply with the requirements of the TS.           |
|                                                                              |
| "At 15:10 [EST] on January 17, 2003, the activities, including retesting     |
| were completed and the breaker was declared operable at which time the plant |
| exited from the TS Limiting Condition for Operability Action.  At this time  |
| the power decrease was stopped.  Power was held stable at 95% awaiting       |
| completion of all paperwork associated with this surveillance test.  Power   |
| ascension commenced at 15:55 [EST]."                                         |

| "At 10:11 hrs on 1/19/2003 Susquehanna Unit 1 began a shut down required by  |
| Technical Specifications.                                                    |
|                                                                              |
| "At 13:06 hrs on 1/16/2003 the 'B' diesel generator was being returned to    |
| service following maintenance. This placed Unit 1 and Unit 2 into a 72 hour  |
| LCO (3.8.1 Cond. B). During its operability run, the governor exhibited      |
| erratic operation and the diesel was shut down. The 'E' diesel generator was |
| re-substituted for the 'B' and an operability run was initiated. During the  |
| run, the 'E' diesel generator tripped on reverse power. Station personnel    |
| continue to troubleshoot the unrelated problems with the diesel generators.  |
| Initial engineering analysis has determined that there is no common mode     |
| failure with these 2 problems or with the remaining 3 operable diesel        |
| generators.                                                                  |

| "The 72 hour LCO for inoperability of 1 Diesel Generator (3.8.1 Cond. B)     |
| will expire at 13:06 hrs today. This will require both Unit 1 and Unit 2 to  |
| enter LCO 3.8.1 Cond. F, which requires both units to be in Hot Shutdown     |
| within 12 hours and Cold Shutdown within 36 hours.                           |
|                                                                              |

| "At 15:38 hrs on 1/19/2003 the 'E' diesel generator was declared operable.   |
| This returned the station to 4 operable diesel generators and allowed        |
| exiting the LCO 3.8.1 Cond. B and Cond. F.  Power reduction on Unit 1 was    |

| "At 1255 hrs on January 19, 2003, Unit 1 was in Mode 1 at 100% power and     |
| Unit 2 was in Mode 3 with Trains A and D reactor coolant pumps (RCP)         |
| running. While placing a surge reactor in the switchyard in service the Unit |
| 1 standby transformer received a lockout and total loss of the North bus.    |
|                                                                              |
| "Unit 1 experienced a loss of offsite power (LOOP) to ESF Trains B & C. Both |
| the Train B & Train C emergency diesel generators (EDG) started as expected. |
| The Train C sequencer operated as expected and the Train C components        |
| automatically loaded, However, the Train B sequencer failed resulting in the |
| manual loading of the Train B components in accordance with station          |
| off-normal procedures. This resulted in TS 3.0.3 entry in Unit 1 due to the  |
| loss of two (2) offsite power sources and the B train EDG (due to the        |
| failure of the B Train sequencer). There was a loss of letdown in Unit 1     |
| when Train C isolated. Letdown was restored at 1313 hrs. At 1345 Unit 1      |
| exited TS 3.0.3 when offsite power was restored to B Train. At 1406, offsite |
| power was restored to C Train. The cause of the fault in the switchyard and  |
| failed Train B sequencer are under Investigation.                            |
|                                                                              |
| "In Unit 2, Train A was aligned to the Unit 1 Standby transformer therefore, |
| Unit 2 experienced a LOOP to ESF Train A. Train A emergency diesel generator |
| automatically started and loaded as expected. As a result of the LOOP, Unit  |
| 2 experienced a loss of circulating water and loss of condenser vacuum. The  |
| Steam Generators (SGs) were already being supplied by the Auxiliary          |
| Feedwater system therefore no interruption to SG cooling. In addition, both  |
| Train A and Train D reactor coolant pumps tripped resulting in entry into TS |
| 3.4.1.2, action B & C (boron control limitations and ensure Rx trip breakers |
| open). There was a loss of charging due to the LOOP resulting in a Loss of   |
| RCP seal injection, however, component cooling water flow to the thermal     |
| barrier maintained seal cooling. Charging has been restored to supply seal   |
| injection. At 1840, when starting RCP 2A, pressurizer PORV 655A opened and   |
| reseated due to a pressure spike. Unit 1 remains at 100% power and Unit 2    |
| remains in Mode 3."                                                          |

| SERVICE WATER SYSTEM VALVE PIT PIPING PENETRATION SEAL                       |
|                                                                              |
| "On 1/20/2003 at 1430 hours, the Beaver Valley Power Station control room    |
| was notified by Engineering that a penetration seal previously installed in  |
| a wall which separates two service water system valve pits may have not been |
| adequate. A review of the supporting analysis shows that this penetration    |
| seal may not be qualified to withstand the hydraulic pressure which could    |
| result from a postulated internal flooding event occurring due to a service  |
| water system pipe failure filling the valve pit and its above compartment    |
| prior to operator intervention. A failure of this seal during a postulated   |
| internal flooding event may result in the loss of motor operated valve       |
| movement in both trains of the service water system that would be needed     |
| following a design basis accident (DBA).                                     |
|                                                                              |
| "This design basis calculation and the penetration seal capability are       |
| continuing to be evaluated. However, this seal could potentially have        |
| prevented the service water system from meeting single failure criterion     |
| during a postulated service water system pipe failure. Therefore, Technical  |
| Specification (TS) 3.7.4.1 was entered due to less than two trains of        |
| service water system being operable as a conservative decision based upon    |
| the limited information immediately available to show acceptable seal        |
| integrity at the postulated conditions. The TS Action requires restoration   |
| of two independent service water system trains within 72 hours. Actions are  |
| in progress to install a qualified seal which will prevent the unacceptable  |
| flooding conditions from being able to occur.                                |
|                                                                              |
| "This condition is being reported pursuant to 10 CFR 50.72(b)(3)(ii) as an   |
| unanalyzed condition that significantly degraded plant safety since this     |
| seal has been installed for five months and may have invalidated the         |
| independence between the two service water system trains. The NRC resident   |
| has been notified of the degraded condition."                                |
