Based on the identified failure mode, the "A" | | D/G breaker was in an inoperable state since the last time it was tripped. | | This occurred following the performance of periodic testing on 5/11/99 @ | | 1148. On 5/11/99 @ 1334, the "B" D/G was declared inoperable for the | | performance of periodic testing, which resulted in both D/Gs being | | inoperable and the plant entering a 3.0.3 TS LCO action statement. | | Therefore, during the periodic testing of the "B" D/G, there would have | | been an inability to automatically respond to an event coincident with a | | loss of offsite power. The "B" D/G was immediately returned to service | | following the test. The "A" D/G was restored to operable status on 6/9/99. | | The licensee notified the NRC Resident Inspector. | | | | * * * UPDATE AT 1519 ON 6/30/99 BY DOUG PETERSEN TO JOLLIFFE * * * | | | | The licensee has concluded that the date and time of inoperability is when | | the "A" D/G output breaker to safeguards bus #14 failed to close (1007 on | | 6/8/99). The "A" D/G was declared operable on 6/9/99, and the time of | | inoperability is within the allowable LCO time frame. Therefore, no | | reportable event occurred and the licensee desires to retract this event. | | | | During troubleshooting, the breaker was successfully closed at the bus | | cubicle more than 20 times on 6/8/99 and 6/9/99 without any adjustment of | | the breaker and without another failure. The apparent cause of the breaker | | failure is attributed to a slight misalignment of the tripper bar on the | | breaker. However, potential effects of bus vibration, temperature, | | lubrication drying, and the randomness of the breaker failure does not | | provide firm evidence of the specific time the breaker became inoperable. | | There is no firm evidence to believe the discrepancy existed prior to | | 6/8/99. Therefore, in accordance with the industry guidance provided in | | NUREG-1022, Revision 1, it should be assumed the discrepancy occurred at the | | time of its discovery. The licensee notified the NRC Resident Inspector. | | | | The NRC Operations Officer notified the R1DO Larry Doerflein. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |General Information or Other |Event Number: 35862 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: ABB COMBUSTION ENGINEERING |NOTIFICATION DATE: 06/25/1999| |LICENSEE: ABB COMBUSTION ENGINEERING |NOTIFICATION TIME: 16:34[EDT]| | CITY: WINDSOR REGION: 1 |EVENT DATE: 06/25/1999| | COUNTY: STATE: CT |EVENT TIME: [EDT]| |LICENSE#: AGREEMENT: N |LAST UPDATE DATE: 06/30/1999| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |GLENN MEYER R1 | | |VERN HODGE (via fax) NRR | +------------------------------------------------+ | | NRC NOTIFIED BY: IAN RICKARD | | | HQ OPS OFFICER: BOB STRANSKY | | +------------------------------------------------+ | |EMERGENCY CLASS: N/A | | |10 CFR SECTION: | | |CCCC 21.21 UNSPECIFIED PARAGRAPH | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | 10CFR PART 21 REPORT REGARDING ABB COMBUSTION ENGINEERING 4KV VACUUM | | BREAKERS | | | | The following text is excerpted from a facsimile received in the NRC | | Operations Center: | | | | "The defect concerns ABB 1200A 4KV Vacuum Breakers delivered to Baltimore | | Gas and Electric Company's (BG&E's) Calvert Cliffs Nuclear Power Plant | | (CCNPP). Specifically, the defect concerns the breaker performing a trip | | free operation when a close signal is received by the breaker. This defect | | results in the breaker failing to remain in the closed position. The defect | | could lead to non-conservative failure of not starting certain plant | | equipment upon demand such as an Emergency Core Cooling Pump." | | | | * * * UPDATE AT 1613 ON 06/30/99 BY VIRGIL PAGGEN TO JOLLIFFE * * * | | | | The above 10CFR Part 21 Report was submitted to the NRC via ABB Combustion | | Engineering Letter #LD-99-035, dated 06/25/99. The following is an update | | to the above 10CFR Part 21 Report via ABB Combustion Engineering Letter | | #LD-99-039, dated 06/30/99, Same Subject. | | | | The activity for which this report is being filed is the use of ABB 1200A | | 4KV Vacuum Breakers in an application where the breaker is normally open and | | must close on demand. This defect applies only to BG&E's CCNPP. | | | | The defect identified is associated with the use of the ABB 1200A 4KV Vacuum | | Breaker only in applications where the breaker must close on demand. The | | defect was detected during site testing of the breaker during installation | | into CCNPP. During this test, a close signal was applied to the breaker and | | the breaker tripped free (i.e., failed to remain in the closed position). | | | | These breakers are intended for both normally open and normally closed | | operation. In some applications, the breaker must close upon demand. This | | may be for electrical distribution applications or component control | | applications (e.g., start an Emergency Core Cooling pump). Demands can be | | automated (e.g., by ESFAS) or based on manual operator demands. If the | | breaker does not remain closed when demanded (i.e., trips free), the safety | | function cannot be performed. This breaker is intended for use in multiple | | redundant safety divisions. Multiple redundant divisions could be affected | | by this defect. | | | | The defect applies only to ABB 1200A 4KV Vacuum Breakers delivered to CCNPP. | | Thirty-seven (37) of these breakers were delivered to CCNPP. ABB | | Combustion Engineering understands that several of these breakers have been | | installed at CCNPP, however, none are installed in any application that | | requires a close on demand function. | | | | The NRC Operations Officer notified the R1DO Larry Doerflein and NRR Vern | | Hodge (via fax). | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 35880 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: SEABROOK REGION: 1 |NOTIFICATION DATE: 06/30/1999| | UNIT: [1] [] [] STATE: NH |NOTIFICATION TIME: 11:50[EDT]| | RXTYPE: [1] W-4-LP |EVENT DATE: 06/30/1999| +------------------------------------------------+EVENT TIME: 09:05[EDT]| | NRC NOTIFIED BY: DANA MORRELL |LAST UPDATE DATE: 06/30/1999| | HQ OPS OFFICER: DICK JOLLIFFE +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |LAWRENCE DOERFLEIN R1 | |10 CFR SECTION: | | |NLTR LICENSEE 24 HR REPORT | | |APRE 50.72(b)(2)(vi) OFFSITE NOTIFICATION | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | 24 HOUR REPORT - DEAD SEAL FOUND | | | | The licensee notified the National Marine Fisheries and the NRC Resident | | Inspector that they discovered a dead seal in the plant intake structure | | during a routine inspection. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 35881 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: OCONEE REGION: 2 |NOTIFICATION DATE: 06/30/1999| | UNIT: [1] [2] [3] STATE: SC |NOTIFICATION TIME: 17:59[EDT]| | RXTYPE: [1] B&W-L-LP,[2] B&W-L-LP,[3] B&W-L-L|EVENT DATE: 06/30/1999| +------------------------------------------------+EVENT TIME: 17:22[EDT]| | NRC NOTIFIED BY: RANDY TODD |LAST UPDATE DATE: 06/30/1999| | HQ OPS OFFICER: DICK JOLLIFFE +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |PAUL FREDRICKSON R2 | |10 CFR SECTION: | | |AOUT 50.72(b)(1)(ii)(B) OUTSIDE DESIGN BASIS | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N N 0 Cold Shutdown |0 Cold Shutdown | |2 N Y 100 Power Operation |100 Power Operation | |3 N Y 100 Power Operation |100 Power Operation | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | - Certain accident scenarios could cause pressurization of Low Pressure | | Injection and Rx Bldg Spray Systems - | | | | During investigation of a valve leak observed during a test on Unit 1, it | | was discovered that there is a possibility that certain accident scenarios | | could cause pressurization of certain portions of the Low Pressure Injection | | (LPI) and Reactor Building Spray (RBS) Systems above values previously | | evaluated. | | | | Specifically, following a small break LOCA, the LPI System is still taking | | suction from the Borated Water Storage Tank (BWST) when the system is | | aligned with the LPI Pump 'A' discharging to both injection headers through | | the crossover piping in preparation for realigning suction to the Reactor | | Building Emergency Sump. At this time, it is possible to pressurize the | | suction piping of the idle LPI Pump 'B' and RBS Pump 'B'. This can occur | | because the LPI Pump 'B' minimum flow recirculation line is connected | | downstream of the pump discharge check valve or as a result of leakage | | through the pump discharge check valve. A small amount of fluid would flow | | through the recirculation line until the pressure in the pump suction piping | | is equal to the pressure in the cross-connected LPI discharge headers. | | (Procedural details would prevent this problem from affecting Train 'A'.) | | | | This pressure could be in excess of the capability of certain valve | | operators to reposition process valves. Among the affected valves is #LP-20, | | the RB Emergency Sump Train 'B' isolation valve. | | | | When nearing depletion of the BWST inventory, the Emergency Operating | | Procedure calls for opening both RB Emergency Sump isolation valves (#LP-19 | | on Train 'A' and #LP-20 on Train 'B'). | | | | It was also recognized that #LP-19, in the redundant flow path, must be | | considered vulnerable to a random single failure. | | | | Therefore, at 1722 on 06/30/99, Oconee Site Managers concluded that #LP-20 | | must be considered inoperable for use in this specific system configuration. | | This configuration is only used during certain small break LOCAs which | | require that the LPI and High Pressure Injection (HPI) Systems be placed in | | the "piggy-back" configuration where the LPI pumps supply flow to the HPI | | pump suctions. In addition, this failure scenario only applies to the | | limited spectrum of small breaks that do not result in initiation of Reactor | | Building Spray. | | | | Because this inoperablity only affects the HPI-LPI "piggy-back" Train 'B' | | flow path, the operating units (Units 2 & 3) entered Tech Spec 3.5.2, | | Condition C, which has a 72 hour action statement. The main corrective | | action is implementation of a system alignment change which will create a | | vent path to the Reactor Building using the Reactor Building Spray Train 'B' | | piping. This will prevent the possibility of pressurizing the piping at | | #LP-20 and eliminate the potential for this problem. The procedure changes | | are in progress and the implementation is expected to occur on night shift | | tonight (06/30/99). In addition, operators on shift will receive awareness | | training on the new configuration as it is implemented. Corresponding | | changes to the Emergency Operating Procedure | | will be implemented prior to exiting the Tech Spec 3.5.2.C action statement. | | Affected Periodic Test, Maintenance, and Instrument Procedures have been | | placed on administrative hold until they can be revised. | | | | Unit 1 is currently in Mode 5 (Cold Shutdown) in a Refueling Outage | | preparing to enter Mode 4. These alignment changes will be incorporated on | | Unit 1, as appropriate, during plant start-up. | | | | The analysis of this issue is continuing, and the potential exists that | | further analysis or testing may allow retraction | | of this notification. If not, further details will be provided in the LER | | that will be submitted to the NRC. | | | | The licensee notified the NRC Resident Inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Transportation |Event Number: 35882 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: SYNCOR INTERNATIONAL CORP |NOTIFICATION DATE: 06/30/1999| |LICENSEE: SYNCOR INTERNATIONAL CORP |NOTIFICATION TIME: 18:00[EDT]| | CITY: NASHVILLE REGION: 2 |EVENT DATE: 06/30/1999| | COUNTY: STATE: TN |EVENT TIME: 12:00[EDT]| |LICENSE#: AGREEMENT: Y |LAST UPDATE DATE: 06/30/1999| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |PAUL FREDRICKSON R2 | | |LINDA HOWELL R4 | +------------------------------------------------+SUSAN SHANKMAN NMSS | | NRC NOTIFIED BY: SCOTT LANGFORD |DON COOL NMSS | | HQ OPS OFFICER: DICK JOLLIFFE | | +------------------------------------------------+ | |EMERGENCY CLASS: N/A | | |10 CFR SECTION: | | |BAB2 20.2201(a)(1)(ii) LOST/STOLEN LNM>10X | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | - OVERDUE SHIPMENT OF MEDICAL RADIOPHARMACEUTICALS (IODINE-131) - | | | | AT 1630 ON 06/25/99, A PACKAGE OF MEDICAL RADIOPHARMACEUTICALS (0.9 | | MILLICURIES OF IODINE-131) WAS SHIPPED BY CAR/TRUCK VIA ASSOCIATED COURIERS | | FROM SYNCOR INTERNATIONAL CORP, ST LOUIS, MO TO SYNCOR, NASHVILLE, TN.

Preliminary indication is that the 'C' outboard MSIV | | went closed, causing the high neutron flux that tripped the reactor. The | | other three steam lines experienced high steam flow resulting in the closure | | of all the steam line isolation valves. As a result of the Reactor Scram | | with MSIV closure, water level dropped to approximately minus 46 inches on | | wide range level instrumentation. Level was restored to 35 inches using | | high pressure coolant injection (HPCI) and reactor core isolation cooling | | (RCIC). Reactor pressure peaked at 1048 psig prior to the scram.
