| BOTH TRAINS OF POST ACCIDENT H2 ANALYZERS DECLARED ADMINISTRATIVELY |
| INOPERABLE. |
| |
| During an ongoing review of calculations for "Normal and Accident Gamma and |
| Beta Doses for Mechanical Equipment Qualifications" it was discovered that |
| an inaccurate assumption was made concerning the operation of the |
| Containment and Drywell post accident hydrogen monitoring system. This |
| inaccurate assumption could lead to the sample isolation valves receiving |
| more radiation exposure than assumed in the calculations curing a design |
| bases accident. This extra radiation exposure could cause deterioration of |
| the valve seats and prevent them from sealing properly. With the valves |
| leaking the indicated hydrogen concentrations could be non-conservatively |
| low leading to improper actions during an accident. This condition affects |
| both safety trains of the post accident hydrogen analyzers. The actual |
| affect is still indeterminate however both trains have been conservatively |
| declared administratively inoperable. The system is still in a standby |
| lineup and is expected to continue to perform its function during the early |
| stages of an accident. Engineering is continuing to evaluate the actual |
| affect of the increased radiation exposure on the equipment. The NRC |
| Resident Inspector will be informed of this event by the licensee. |
| |
| * * * UPDATE AT 1713 ON 3/1/2000, BY FELTNER RECEIVED BY WEAVER * * * |
| |
| On 2/3/2000, (event notification 36657), River Bend Station reported that |
| the Containment and Drywell hydrogen monitor system had been conservatively |
| declared inoperable. The inoperability was based on the impact of an |
| inadequate assumption in a post accident dose calculation for the system |
| sample valves. This could have lead to more post accident radiation |
| exposure than determined in the original calculation, which may have lead to |
| failure of the sample valves to properly seat. At the time of the original |
| report. the actual affect of the condition on the valves was indeterminate |
| and the system was declared inoperable. Engineering re-evaluated the |
| condition as documented in a revision to calculation PR(c) 547. This |
| calculation found that the original assumption in the calculation did not |
| impact system operability. The calculation states that the potential doses |
| due to plateout in the system would be negligible when compared to the |
| airborne beta doses, and therefore the doses presented in the original |
| calculation conservatively represent dose expected following a design basis |
| accident. Based on this the system it was determined to be operable, and |
| the condition not reportable. The licensee notified the NRC resident |
| inspector. The NRC Operations Center notified the RDO (Cain). |

| - OVERDUE SHIPMENT OF NEW FUEL - |
| |
| The licensee reported that a shipment of new fuel from General Electric was |
| due to arrive onsite at 0500 on 03/01/00. The shipper (Kindrick Trucking |
| Company) was contacted and the shipment was located in Canton, Ohio, at 0550 |
| on 03/01/00. The new expected arrival time is 0900 on 03/01/00. The |
| licensee notified the NRC Resident Inspector. |
| |
| * * * UPDATE AT 0955 ON 03/01/00 BY PAT FALLON TO JOLLIFFE * * * |
| |
| General Electric notified the licensee that the reason for the delay was |
| that a tarp on the nuclear fuel truck blew off and is being recovered and |
| reinstalled on the truck. Estimated time of arrival onsite now is 1300 on |
| 03/01/00. The licensee plans to notify the NRC Resident Inspector. The NRC |
| Operations Officer notified R3 IAT Jim Creed, R3DO Mike Jordan, NRR IAT Dick |
| Rosano, NRR EO Chris Grimes, NMSS IAT Mike Weber, NMSS EO Brian Smith, and |
| IRO Frank Congel. |
| |
| * * * UPDATE AT 1254 ON 3/1/2000 BY COSEO TAKEN BY WEAVER * * * |
| |
| The licensee is retracting this event. |
| |
| "10 CFR 73.67(g)(3) states that each licensee, either shipper or receiver, |
| who arranges for the physical protection of special nuclear material of low |
| strategic significance while in transit or who takes delivery of such |
| material free on board (f.o.b.) the point at which it is delivered to a |
| carrier for transport shall: conduct immediately a trace investigation of |
| any shipment that is lost or unaccounted for after the estimated arrival |
| time and notify the NRC Operations Center within one hour after the |
| discovery of the loss of the shipment and within one hour after recovery of |
| or accounting for such lost shipment in accordance with the provisions of 10 |
| CFR 73.71. In accordance with a General Electric (GE) letter to Detroit |
| Edison, dated August 12, 1992, GE stated that they are responsible for |
| in-transit physical protection of fuel shipments from Wilmington to the |
| Fermi 2 site. Therefore, the notification to the NRC regarding lost or |
| unaccounted for special nuclear material of low strategic significance while |
| in transit should have been completed by GE. |
| |
| "However, further evaluation of the event revealed that communication |
| between GE and the truck driver regarding the trucks location and problem, |
| did occur. Therefore, the truck was never lost or unaccounted for by GE. The |
| delay in the estimated arrival time was apparently due to problems with the |
| truck during the transit. Based on the above information and the fact that |
| the shipment was never lost or unaccounted for, the reporting requirements |
| of 10 CFR 73.71 do not apply in this event. Therefore, Detroit Edison is |
| retracting the 1-hour notification." |
| |
| The licensee notified the NRC resident inspector and the Operations Center |
| notified the RDO (Jordan), EO (Smith), IRO (Congel). |

| AMERICIUM-241 SEALED SOURCE DISCOVERED TO BE MISSING FROM ALLEGHENY GENERAL |
| HOSPITAL LOCATED IN PITTSBURGH, PENNSYLVANIA. |
| |
| At approximately 1030 on 03/01/00, representatives at Allegheny General |
| Hospital located in Pittsburgh, Pennsylvania, discovered that a |
| 14-millicurie, americium-241, sealed source was missing from a stationary |
| gamma camera. The licensee reported that the source was last seen at 1130 |
| on 02/29/00. |
| |
| The licensee stated that the source is a relatively low level source with |
| longevity which is used to mark images. It is about the size of a pencil |
| eraser, and it is typically glued into a holder on the gamma camera. |
| |
| The licensee currently believes that the source may have become dislodged |
| from the holder and that it may have fallen to the floor. If that occurred, |
| the source may have been placed in the trash when the room was cleaned the |
| on the evening of 02/29/00. The licensee's investigation is ongoing, and |
| surveys are underway. |
| |
| The licensee plans to notify the state inspector. (Call the NRC operations |
| officer for a licensee contact telephone number.) |

| OUTSIDE DESIGN BASIS - NON CONSERVATIVE LIMITING CONDITION FOR OPERATION |
| |
| On March 1, 2000, at 1215 hours, resulting from evaluations performed in |
| response to the McGuire Station Notification (02/04/2000, event # 36659), |
| Virgil C. Summer Nuclear Station has determined that a condition outside of |
| design basis may have existed during past plant operation. |
| |
| The specific condition is a deficiency in the current Limiting Condition for |
| Operation for Engineered Safety Feature Actuation System (ESFAS) |
| instrumentation. For one inoperable channel (in the Emergency Feedwater |
| suction swap over on low suction pressure, RWST [Reactor Water Storage Tank] |
| swap over to RB [Reactor Building] Sump on low level, and/or Containment |
| Spray actuation on High-3 pressure) the Technical Specification (TS) action |
| is to place the channel in bypass with no Allowed Outage Time (AOT) limit. |
| These are energize to actuate functions. At this point the actuation logic |
| changes from 2 out of 4 to 2 out of 3. |
| |
| Because of the indefinite period of time that this condition is permitted to |
| remain in effect, this condition cannot be considered a single failure |
| during a design basis accident. During a design basis accident, a single |
| failure involving a loss of power to the opposite train instrumentation, |
| while one or more of these functions were in bypass, would prevent the |
| safety function from automatically occurring. Manual operator action is |
| specified in the station Emergency Operating Procedures. |
| |
| Currently all four channels for each of the above functions are OPERABLE. |
| Therefore, Summer is not operating with a single failure vulnerability at |
| this time. A preliminary PRA [Probability Risk Assessment] assessment shows |
| the change in Core Damage Frequency to be 2.4 E-8 for placing one channel |
| from each of these functions in bypass indefinitely. |
| |
| Administrative controls have been developed to limit the AOT for these |
| particular channels to be in bypass until such time as a TS change request |
| can be submitted and approved. |

| STATION ELECTRICAL LOADS FROM THE STARTUP TRANSFORMER TO THE "M1A" |
| AUXILIARY TRANSFORMER, STARTUP TRANSFORMER "A" BREAKER "S1A" OPENED AS |
| EXPECTED BUT "1A" BREAKER DID NOT CLOSE. THE FAILURE OF BREAKER "1A" TO |
| CLOSE RESULTED IN A LOSS OF ELECTRICAL POWER TO BOTH NON-VITAL BUS "A" AND |
| VITAL BUS "C". |
| |
| THE LOSS OF NON- VITAL BUS "A" CAUSED THREE OF FIVE REACTOR RECIRCULATION |
| PUMPS TO TRIP. THE OPERATORS MANUALLY SCRAMMED THE REACTOR IN ACCORDANCE |
| WITH PROCEDURES. ALL CONTROL RODS FULLY INSERTED INTO THE CORE. LOSS OF |
| ELECTRICAL POWER TO VITAL BUS "C" CAUSED A LOSS OF POWER TO 1/2 OF THE |
| REACTOR PROTECTION SYSTEM. THIS RESULTED IN VITAL BUS EMERGENCY DIESEL |

| ISOLATION VALVES CLOSED WHEN REACTOR VESSEL PRESSURE DECREASED BELOW 850 |
| PSIG. |
| |
| AT THE PRESENT TIME THE ISOLATION CONDENSER IS BEING USED TO COOL THE |
| REACTOR VESSEL DOWN. WHEN REACTOR PRESSURE DROPS BELOW 100 PSIG THE MAIN |
| STEAM ISOLATION VALVES CAN BE REOPENED. OFFSITE POWER HAS BEEN RESTORED TO |
