At 0757 PST with Unit 2 at nominal full reactor power a load | | transient bypass (LTB) signal was initiated diverting main feedwater around | | the normal feedwater heaters into the steam generators. During the resultant | | sudden temperature decrease, reactor power peaked at 103.8% and exceeded the | | nominal full power for a total of six minutes. | | | | "The transient was initiated by utility maintenance personnel during the | | scheduled performance of instrumentation calibration of circuits associated | | with the LTB. Technicians performing a calibration inadvertently disturbed | | an input circuit creating an invalid LTB initiate signal. | | | | "The feedwater temperature was rapidly reduced approximately 45 to 50 | | degrees F. The Final Safety Analysis Report Update Chapter 15, 'Accident | | Analyses,' Condition II, 'Faults of Moderate Frequency,' Section 15.2.11, | | 'Sudden Feedwater Temperature Reduction,' provides bounding analysis for | | this event. The FSAR Update concludes that for temperature drops of less | | than 73 degrees F that the reactor will remain in operation and the reactor | | will not go below the minimum DNBR. FSAR Update Section 15.2.11.1 analysis | | specifically identifies the inadvertent actuation of the LTB as an | | initiating event bound by the analysis.) | | | | "The DCPP Unit 2 Operating License DPR-82, Condition 2.C(1) authorizes PG&E | | to operate Unit 2 at reactor core power levels not in excess of 3411 | | megawatts thermal (100% rated power). DPR-82, Condition 2.G, 'Reporting,' | | requires Emergency Notification System reporting within 24 hours and a | | written followup report within 30 day in accordance with the procedures | | described in 10 CFR 50.73(b), (c), and (e).

This | | investigation found that an unauthorized manufacturing process change | | occurred between August 4, 1997 (date code 9732) and March 12, 1999 (date | | code 9911) which allowed an interrupted seal on some portion of the covers | | manufactured, compromising the environmental and electrical protection | | requirements. | | | | Foxboro is taking immediate action to notify all customers who purchased | | this product from The Foxboro Company during the time period affected and to | | provide replacement covers. | | | | Indian Point Unit 3 and Cook Units 1 and 2 may be affected by this problem. | | | | Foxboro plans to submit a written report to the NRC on this 10 CFR Part 21 | | Report. | | | | (Call the NRC operations center for contact information.) | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 36808 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: NINE MILE POINT REGION: 1 |NOTIFICATION DATE: 03/17/2000| | UNIT: [] [2] [] STATE: NY |NOTIFICATION TIME: 14:15[EST]| | RXTYPE: [1] GE-2,[2] GE-5 |EVENT DATE: 03/17/2000| +------------------------------------------------+EVENT TIME: 10:20[EST]| | NRC NOTIFIED BY: GREG PITTS |LAST UPDATE DATE: 03/17/2000| | HQ OPS OFFICER: LEIGH TROCINE +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |LAURIE PELUSO R1 | |10 CFR SECTION: | | |AESF 50.72(b)(2)(ii) ESF ACTUATION | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ | | | |2 N N 0 Refueling |0 Refueling | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | LOSS OF TWO DIVISION 2 SERVICE WATER SYSTEM (SWP) PUMPS WHILE ONE DIVISION 1 | | PUMP WAS OUT OF SERVICE | | | | The following text is a portion of a facsimile received from the licensee: | | | | "At time 1020 hours on 03-17-00, Nine Mile Point Unit 2 entered Special | | Operating Procedure (SOP) N2-SOP-11 for loss of service water. | | Specifically, the Division 2 SWP pumps 2SWP*P1B [and] 2SWP*P1D tripped due | | to a low flow condition. Operations personnel were restoring the Service | | Water System (SWP) in accordance with procedure N2-PM-@12, attachment 2, to | | align Division 1, following the Division 1 AC electrical bus outage. A lead | | was re-landed in the Division 1 SWP logic. A failed component in this | | Division 1 SWP logic caused the safety-related to non-safety-related | | isolation valves to isolate. 2SWP*P1C remained in service when the Division | | 2 pumps tripped. Subsequently, [the] SWP system was restored to a [one] | | pump per division line-up.

BRAGG (NORTH CAROLINA) SINCE | | APRIL 1996 | | | | Late yesterday afternoon (03/16/00), representatives from Ft. Bragg, North | | Carolina, requested the U.S. Army in Rock Island, Illinois, to help trace | | files for documentation regarding a cell module that was discovered to be | | missing from an M43A1 chemical agent detector. (The cell module contained | | 250 �Ci of americium-241.) The most recent documentation found related to | | the missing cell module indicated that it was last seen at Ft. Bragg in | | April of 1996. More recent paperwork has not yet been found. The licensee | | determined this event to reportable at approximately 1200 CST today | | (03/17/00). | | | | The licensee hypothesized that the M43A1 chemical agent detector may have | | been turned into a maintenance unit at some point. If the device tested | | with bad air flow, the maintenance unit could have replaced several items | | including the cell module. At this time, it is believed that the cell | | module in question may have been removed (without any paperwork) and that | | the device may have been returned without a replacement cell module | | installed. | | | | The licensee stated that there does not appear to be any likelihood that the | | general public will get involved with this issue. The licensee plans to | | submit a 30-day written report to the NRC Region 3 office. | | | | (Call the NRC operations officer for licensee contact information.) | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 36810 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: BRAIDWOOD REGION: 3 |NOTIFICATION DATE: 03/17/2000| | UNIT: [1] [] [] STATE: IL |NOTIFICATION TIME: 16:52[EST]| | RXTYPE: [1] W-4-LP,[2] W-4-LP |EVENT DATE: 03/17/2000| +------------------------------------------------+EVENT TIME: 15:15[CST]| | NRC NOTIFIED BY: TERRENCE DORAZIO |LAST UPDATE DATE: 03/17/2000| | HQ OPS OFFICER: LEIGH TROCINE +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |JOHN JACOBSON R3 | |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 Y 66 Power Operation |66 Power Operation | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | AS-FOUND TEST VALUES FOR 8 OF 20 MAIN STEAM SAFETY VALVES WERE OUT OF | | TOLERANCE HIGH. | | | | The preliminary results on the analysis of testing of the main steam safety | | valves indicates that the plant was operating outside the design bases.
