| HIGH PRESSURE COOLANT INJECTION (HPCI) DECLARED INOPERABLE DURING TESTING |
| |
| During a test of HPCI, the flow controller failed as the controller was |
| being transferred from manual to balance. The system was manually tripped |
| and remains inoperable. The system impacted is the High Pressure Coolant |
| Injection and the cause is being investigated. The plant is also in a LCO |
| action statement. Corrective action is being implemented to correct this |
| single train system failure. |
| |
| The NRC Resident Inspector was notified. State and local agencies will be |
| notified. |
| |
| *** EVENT RETRACTION BY TIM WITSCHEN TO ERIC THOMAS AT 1600 EST ON 4/4/03 |

| |
| "Event report 39583 was determined not to be reportable. The HPCI system |
| would have been able to perform its safety function of automatically |
| delivering 2700 gpm to the reactor within 45 seconds of initiation signal in |
| the event of a loss of coolant accident, and to mitigate the consequences of |
| a high energy line break. [Therefore], this event is being retracted." |

| REACTOR VESSEL HEAD DEGRADED CONDITION |
| |
| "During the unit 1 cycle 12 refueling and steam generator replacement |
| outage, an inspection was performed of the vessel head in accordance with |
| NRC Order EA-03-009. This bare metal inspection identified a potential leak |
| indication at the head to penetration interface for CRDM (Control Rod Drive |
| Mechanism) penetration #3. On March 26, 2003, at approximately 1012 hours |
| EST, it was decided that the chemical samples have confirmed that the |
| residue found at this interface contains boron, iron, and zinc, indicating |
| that this was an RCS leak. This leak is most likely from a through wall |
| crack in the RCS pressure boundary at the CRDM interface. Volumetric exams |
| are planned to confirm the crack and to determine the scope of any repairs. |
| In accordance with the Order, a 100% volumetric inspection is being prepared |
| for this outage. Prior to this identification, this unit was rated as a |
| 'low susceptibility category.' There had been no indication of RCS leakage |
| during the previous cycle's operation. This notification is being made in |
| accordance with 10 CFR 50.72(b)(3)(ii)(A)." |
| |
| The licensee has notified the NRC Resident Inspector. |
| |
| *****UPDATE ON 4/4/03 AT 1355 FROM LEAHY TO LAURA***** |
| |
| "The purpose of this notification is to update event #39704 concerning a |
| potential pressure boundary leak at CRDM #3. TVA has completed both UT and |
| PT examinations of CRDM #3. The results of these exams do not provide any |
| indication of a crack in the RCS pressure boundary. Investigations are |
| continuing as to the source of the residue found at the penetration. Based |
| on the results of the vessel head examination, this investigation is |
| focusing on determining whether the residue was a result of a prior leak |
| from a non-RCS pressure boundary location." |
| |
| Notified R2DO (A. Boland) |
| |
| *****RETRACTED ON 4/4/03 AT 1702 EST FROM LEAHY TO LAURA***** |
| |
| "The purpose of this notification is to retract the original 10 CFR 50.72 |
| notification described in event notification #39704. |
| TVA's previous update to this notification stated that we had no indication |
| of a pressure boundary crack and that we were continuing to investigate the |
| source of the residue found near CRDM penetration #3. Isotopic analysis |
| (Cesium isotopes) of the boron residue from the head now confirmed that the |
| residue was over 10 years old and likely the result of a conoseal leak that |
| occurred in that period. As such, TVA is retracting the original |
| notification." |

| AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE |
| |
| The following information was received from the Texas Department of Health, |
| Bureau of Radiation Control via facsimile: |
| |
| "The gauge operator was working a night assignment. After completion he |
| took his company vehicle to the company office to complete paperwork at |
| approximately 11:20 p.m. After completion of the paperwork he returned to |
| his vehicle at approximately 11:40 p.m. and discovered that his assigned CPN |
| nuclear density gauge (Model MC1-DR, Serial No. MD0129983) with two sealed |
| radiation sources: a 10 millicurie Amersham, Model CPN 131, cesium-137 |
| capsule, Serial No. 2870, that is engraved on the source rod as "CS9983" |
| (source type plus the last four digits of the gauge Serial No.); and a 50 |
| millicurie Amersham, Model CPN131, americium-241/beryllium, Serial No. 0992, |
| that is engraved on the gauge's internal source pedestal as "AM9983" (source |
| type plus the last four digits of the gauge Serial No.), was missing from |
| the truck. The Licensee's security chain had been cut and was left in the |
| vehicle. The 'red' transport case had been locked but the Licensee reports |
| finding a piece of it's lock, also cut, in the bed of the truck. However, |
| the transport case was also missing. In addition, the gauge's rod handle was |
| also locked within the case before the gauge was stolen. The Licensee also |
| reported that nothing except the gauge and it's case were removed from the |
| truck. This Agency has searched Agency Open Records requests back through |
| January 2002, with no suspicious request noted." |
| |
| There is no media attention at this time. The Licensee is considering |
| whether or not to post a reward for return of the gauge. |

| AUTOMATIC REACTOR SCRAM AT BRUNSWICK DURING START-UP FROM REFUELING OUTAGE |
| |
| "On April 4, 2003, during a Unit 2 reactor start up, primary containment |
| group 1 isolation was received which resulted in a reactor scram. Following |
| the scram, reactor water level lowered to approximately 150 inches. This is |
| below the Reactor Water Low Level One set point of 166 inches. As a result |
| of the low water level, primary containment group 2, 6, & 8 isolation |
| signals were received. All required isolations occurred as a result of the |
| Reactor Water Low Level One isolation signal. All control rods fully |
| inserted on the scram. Reactor Core Isolation Cooling was manually started |
| and Reactor water level was restored to the normal band. Reactor Core |
| Isolation Cooling was shutdown after Reactor water level was restored. |
| |
| "It is believed that the cause of the group 1 isolation signal (Main Steam |
| Isolation Valve closure Scram signal) was an Electro-hydraulic Control (EHC) |
| malfunction that caused the Main Turbine Bypass valves to open. This |
| resulted in the Main Steam Line pressure dropping below the group 1 set |
| point of 850 psig. Investigation is ongoing to determine the exact cause of |
| the EHC malfunction." |
| |
| The NRC Resident Inspector was notified. |

| OFFSITE NOTIFICATION OF POTENTIAL FUEL OIL SPILL |
| |
| "Operations was notified by site chemistry management that a report of a |
| potential fuel oil spill was being made to the North Carolina Department of |
| Environmental Health and Natural Resources, Regional Division of Water |
| Quality. Diesel fuel oil has been identified seeping onto the floor of the |
| Augmented Off-Gas (AOG) building. A diesel fuel oil transfer line from the |
| off-load station to a fuel oil storage tank runs underground in the vicinity |
| of the AOG building and is suspected as the source of the leak. The quantity |
| of the leakage is not known at this time. A follow-up discussion with the |
| Division of Water Quality personnel is scheduled for Monday, April 7, 2003, |
| when more information will be available. |
| |
| "Initial safety significance of this event is zero because this does not |
| affect operation of the Units." |

| PLANT SHUTDOWN REQUIRED BY TECHNICAL SPECIFICATIONS |
| |
| "On April 4, 2003, at 1824 PST, with Unit 2 at approximately 54 percent |
| power, operators commenced a shutdown to mode 5 in accordance with technical |
| specification 3.7.5 C. 1, 'Auxiliary Feedwater (AFW) System,' due to two AFW |
| trains determined to be inoperable. |
| |
| "While trouble-shooting leaking AFW check valves, AFW discharge check valve |
| (FW-2-377) to steam generator (SG) 2-1 was determined to be inoperable due |
| to incorrect installation. Based on radiography, the check valve appears to |
| be installed incorrectly such that it may not allow sufficient AFW flow to |
| SG 2-1. This condition renders two trains of AFW inoperable. |
| |
| "The two motor-driven and one turbine-driven AFW pumps and their flow paths |
| to the other three SGs remain operable. The system is designed such that |
| design basis decay heat can be removed by a single AFW pump delivering flow |
| to at least two SGs. |
| |
| "Unit 2 had ended the recent refueling outage on March 25 and had yet to |
| reach full power when this problem was discovered. Check Valve FW-2-377 had |
| been disassembled during this refueling outage." |
| |
| The licensee has notified the NRC Resident Inspector. |
