| 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." |
| |

| |
| |
| "Beaver Valley Power Station (BVPS) Unit No. 2 retracts the notification |
| made on 01/20/2003 at 20:13 hrs [EST] regarding the event reported under 10 |
| CFR 50.72(b)(3)(ii)(B) [ENS #39526]. The previous notification identified a |
| potential issue with a seal penetration which may have invalidated the |
| independence between two Service Water System trains. |
| |
| "Subsequent analysis of the event identified that the installed penetration |
| seal between the two Service Water System valve pits would have been capable |
| of performing its intended safety function. Therefore, the separation and |
| independence between the two Service Water System trains, as required by |
| Technical Specification 3.7.4.1, would have been satisfied. |
| |
| "Given that both trains of the Service Water System were able to perform |
| their safety functions, this was not a condition that significantly degraded |
| plant safety." |

| PRIMARY CONTAINMENT MEASURED LEAKAGE EXCEEDS THE ALLOWED LEAKAGE. |
| |
| During routine scheduled LLRT (Local Leak Rate Testing) of Penetration |
| X-214, HPCI (High Pressure Coolant Injection) Exhaust Discharge to the |
| Torus, leakage was unable to be quantified. Additionally, of the two |
| isolation check valves in the line, the licensee could not determine which |
| one was leaking. As such, Primary Containment Allowed Leakage (La) is |
| unable to be verified to be less than allowed. |
| |
| The plant was in Mode 4 (Cold S/D) for a scheduled refueling outage with |
| temperature being maintained between 130 and 145 degrees Fahrenheit and |
| Primary Containment not required at the time of discovery. The plant will |
| remain in cold shutdown until repairs are completed. |

| |
| "On 3/2/03 at 0943 CST, Cooper Nuclear Station made an 8 hour 50.72 |
| non-emergency notification to the NRC. This was done due to the failure of |
| Local Leak Rate Testing (LLRT) involving the High Pressure Coolant Injection |
| (HPCI) exhaust discharge to the Suppression Chamber. Leakage was unable to |
| be quantified. Additionally, of the two isolation check valves in the line, |
| testing was unable to determine which one was leaking. |
| |
| "Based on indications of leakage during the LLRT, maintenance activities |
| were started on one of the valves (HPCI-15CV). Upon removal of the |
| HPCI-15CV bonnet it was noticed that the valve was not properly seated. |
| Engineering is continuing to evaluate this condition. To facilitate |
| continuing troubleshooting HPCI-15CV was manually closed by pushing the disk |
| into the valve seat. The bonnet was re-installed and the LLRT was repeated. |
| The other check valve in this line (HPCI-44) was not touched or manipulated |
| during the period of time between successive LLRT's. |
| |
| "The results of the repeat LLRT were well within acceptance criteria limits |
| demonstrating that HPCI-44 was properly performing its containment isolation |
| function. Since HPCI-44 was working properly, the conditions that required |
| an 8 hour 50.72 notification no longer apply. The penetration was always |
| capable of performing the containment isolation function. |
| |
| "The NRC Resident Inspector was notified." |

| PLANT DECLARED UNUSUAL EVENT DUE TO REACTOR TRIP WITH LEAKAGE FROM CHARGING |
| SYSTEM |
| |
| A reactor automatic trip was received at 1439 EST. The cause of the trip is |
| unknown and investigation continues, although reactor protection system |
| testing was in progress at the time of the trip. All systems responded |
| normally with the exception of the charging system. The licensee declared |
| an unusual event at 1516 EST due to charging pump discharge relief valves |
| lifting thereby creating leakage into the auxiliary building. |
| Preliminarily, the cause of the relief valve discharge was blockage in the |
| normal charging line downstream. Charging flow was reestablished via the |
| alternate flowpath. A minimal radioactive release from the auxiliary |
| building ventilation resulted from the charging system leakage. |
| |
| The NRC Resident Inspector was notified. State and local officials were |
| notified and the licensee issued a press release. |

| SAFETY INJECTION SYSTEM ACTUATION AND CAUSE UNDER INVESTIGATION |
| |
| "At 20:47 on 3/9/03, Unit 2 experienced a Safety Injection while the plant |
| was stable at NOP(2235 psig)/NOT |
| (567 degrees) in Mode 3. All systems actuated as designed. An operator was |
| operating the 'B' S/G PORV shortly |
| before the event occurred. All MSIVs were closed for ongoing work on the |
| main turbine. The Sequence of |
| events report showed all 3 channels of steam pressure spiking low on the 'B' |
| Steam Generator as the cause of the event. Initial look at trends on the |
| integrated computer system showed [that] steam pressure channels did not |
| lower to a point to cause the safety injection. An Event Review Team is |
| being formed to investigate this event. |
| |
| "A Reactor Coolant System PORV opened due to high pressure when the Spray |
| valves closed due to the Instrument Air isolation (due to phase 'A') with |
| the Pressurizer Heaters in manual. The Pressurizer heaters were secured and |
| Reactor coolant System pressure stabilized. All ESF systems actuated as |
| designed. The following systems actuated: Auxiliary Feedwater, Safety |
| Injection, Phase 'A', Control Room Envelope and Fuel Handling Building HVAC |
| systems, Essential Cooling Water, Component Cooling Water, Emergency Diesel |
| Generators and ESF sequencers." |
| |
| There was no safety injection since pressure was maintained above 2199 psi |
| during the transient (Hi Head is 1700 psi). Heat removal is being performed |
| through S/G PORVs and Unit 2 is currently stable at Mode 3. |
| |
| The Licensee notified the NRC Resident Inspector. |

EVENT TEXT
+------------------------------------------------------------------------------+
| AUTOMATIC REACTOR TRIP DUE TO TURBINE TRIP ON GENERATOR DIFFERENTIAL RELAY |
| ACTUATION |
| |
| "At 0012 EST on March 10, 2003, with Watts Bar Unit 1 in Mode 1 at 100% |
| power, the reactor tripped due to an automatic signal. All plant safety |
| systems were in service at the time to the trip, except for the 2B-B diesel |
| generator which was out of service for scheduled maintenance, and all |
| [safety systems] responded as designed. All control rods inserted as |
| required and the Auxiliary Feedwater System [AFW] initiated as expected. |
| |
| "The reactor trip resulted from a turbine trip signal that was generated as |
| a result of a main generator/transformer differential electrical relay |
| actuation. The plant is currently stable in Mode 3 and will remain in this |
| Mode until completion of the investigation." |
| |
| AFW was removed from operation and the main feed pumps have resumed normal |
| feed to the Steam Generators. The Licensee notified the NRC Resident |
| Inspector. |
