| THREE SPRINKLER SYSTEMS DECLARED INOPERABLE DUE TO CORRODED HEADS (24-hour |
| report) |
| |
| The following text is a portion of a facsimile received from Paducah: |
| |
| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent (PSS) was notified |
| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems |
| in C-337 and 1 system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question. Subsequently, these |
| sprinkler systems were declared inoperable, and TSR-required actions |
| establishing roving fire patrols were initiated. This deficiency was |
| detected during scheduled system inspections conducted by Fire Protection |
| personnel. Currently, functionality of the sprinkler heads has not been |
| fully evaluated by Fire Protection personnel, and the remaining cascade |
| buildings are currently being inspected, and if necessary, this report will |
| be updated to identify any additional areas. |
| |
| "It has been determined that this event is reportable under |
| 10CFR76.120(c)(2) as an event in which equipment is disabled or fails to |
| function as designed." |
| |
| The NRC resident inspector has been notified of this event. |

| |
| The following text is a portion of a facsimile received from Paducah: |
| |
| "Two sprinkle heads on system D-1 in C-337 and two sprinkler heads on system |
| 27 in C-335 were identified to also be corroded. These were identified to |
| the PSS on 06/03/99 at 1600 CDT and 1601 CDT, respectively, and determined |
| to require an update to this report by the PSS. |
| |
| "It has been determined that this event is reportable under |

| INADVERTENT ESF ACTUATION. |
| |
| During preparations for overspeed surveillance testing of the D23 diesel |
| generator an inadvertent 'C' emergency service water pump start signal was |
| received causing the pump to start. The cause of the event was personnel |
| error by an I&C technician during installation of a speed signal generator. |
| The speed tachometer was being calibrated and was set at 900 rpm when the |
| speed signal generator used for overspeed testing was hooked up. Normally |
| the calibration would be complete and the signal generator set at zero rpm |
| prior to hookup. All systems responded as expected. |
| |
| The NRC resident inspector was notified. |

| ACTUATION OF A "Q" SAFETY SYSTEM. |
| |
| At 1631 hours on 6/16/99, operations personnel responded to a high voltage |
| outleakage smokehead alarm at the X-333 Low Assay Withdrawal (LAW) condenser |
| accumulator area. Operators responded per alarm response procedures and |
| checked for outleakage and observed smoke at Instrument Control Panel (ICP) |
| Number 13. Operators immediately evacuated the area, called 911, and |
| initiated a building recall. |
| |
| The Emergency Response Organization (ERO) responded and monitored air |
| quality for hydrogen fluoride, airborne radioactivity, and surveyed for |
| surface contamination. All sample results were less than minimum detectable |
| activity. Investigation determined that a Dalton fitting in ICP#13 was |
| cross threaded and was considered a possible source of the outleakage. |
| |
| This is reportable as a valid actuation of a "Q" safety system in accordance |
| with Safety Analysis Report, Section 6.9 (24-Hour Report). |
| |
| The NRC resident inspector has been notified. |

| INADVERTENT ESF ACTUATION. |
| |
| During the performance of a scheduled surveillance 2-SR-3.3.5.1.2(ATU |
| C)/Core and Containment Cooling Systems Analog Trip Unit Functional Test, |
| Relay 2-RLY-073-23A-K36 was required to have inhibits (boots) installed to |
| prevent HPCI valves (PCIS GP-4 isolation) from actuating due to a simulated |
| high steam flow condition. At 1337 CDT on June 17, 1999, Unit 2 received a |
| group 4 HPCI isolation during the performance of step 7.15.15 of the |
| surveillance procedure. The licensee determined that the wrong contacts had |
| been inhibited allowing the actuation to occur. The inhibits were removed |
| and the PCIS GP-4 isolation was reset at 1402 CDT returning HPCI to an |
| operable condition. |
| |
| The licensee notified the NRC resident inspector. |

| ESF ACTUATION. |
| |
| At 1722 CDT the 2D primary containment vacuum breaker 2PC001D went from the |
| closed (normal) position to an indicated dual position. The valve is |
| actuated by a differential pressure between the suppression chamber and the |
| drywell air space and is designed to open at 0.5 psid or less. Differential |
| pressure at 1722 CDT was 0.23 psid. An operator was dispatched and the |
| containment vacuum breaker was manually cycled. After being manually cycled |
| the containment vacuum breaker returned to the closed position. The |
| licensee subsequently satisfactorily performed an operability test on the |
| containment vacuum breaker. |
| |
| The licensee has notified the NRC resident inspector. |

| INFORMATION CALL - A FIRE ON OWNER CONTROLLED PROPERTY |
| |
| A fire of yet undetermined origin was discovered by a janitor at |
| approximately 2240 hours, Thursday, June 17, in a temporary office trailer, |
| north of the Palisades Training Building. The trailer complex is located |
| one-half mile from the operating plant. There was no impact to the Training |
| Building or the plant's operation, and the plant remained at full power. |
| |
| The control room was notified after discovery of the blaze. The control room |
| dispatched the plant's fire brigade and Covert Fire and Ambulance department |
| to the scene. The plant fire brigade began immediate setup of hoses and |
| began initial fire fighting until the Covert Fire department arrived, some |
| 15 minutes later. |
| |
| Cause of the fire has not been determined. An investigation will be |
| initiated. There were no injuries and no one was in the trailer office at |
| the time. |
| |
| A safety inspection will be conducted today of all plant offices and |
| trailers for potential fire hazards. |

| ESF ACTUATION - VACUUM BREAKER |
| |
| At 0250 CDST 2PC001D, the 2D Primary Containment Vacuum Breaker went from |
| the (normal) closed position to an indicated dual position. Locally it was |
| determined that the valve was just cracked open. The valve is designed to |
| open when Suppression chamber pressure is approximately 0.5 psig greater |
| than Drywell pressure. When the vacuum breaker opened the aforementioned |
| differential pressure was approximately 0.2 psid. The vacuum breaker was |
| closed by an Equipment Attendant and then cycled per LOS-PC-M2 "Unit 2 |
| Drywell-Suppression Pool Vacuum Breaker Operability Test for Condition 1,2 |
| and 3" to verify proper operation. The valve cycled satisfactorily. |
| |
| The licensee notified the NRC resident inspector. |
