THE LICENSEE CLEANED UP THE OIL AND REMOVED THE AFFECTED SOIL. | | | | THE LICENSEE PLANS TO INFORM THE NRC RESIDENT INSPECTOR. | | | | * * * UPDATE 1431EDT ON 5/18/99 FROM BRIAN WEAVER TO S.SANDIN * * * | | | | The licensee is retracting this report based on the following: | | | | "At 1507 on 4/19/99, a 4-hr non-emergency phone notification was made to the | | NRC by this facility regarding an 11 gallon hydraulic oil spill on paved and | | unpaved areas from a rupture on a forklift hydraulic line under the category | | of 10CFR 50.72(b)(2)(vi), Any event or situation, related to the health and | | safety of the public or onsite personnel, or protection of the environment, | | for which a news release is planned or notification to other government | | agencies has been or will be made. | | | | "Subsequent review of the site reportability procedure and 10CFR | | 50.72(b)(2)(vi) has determined that this event is not reportable under that | | statute, specifically that the oil spill was not environmentally significant | | in that the volume was actually only 2.5 gallons and that the spill was | | immediately contained and cleaned up such that no oil reached ground or | | surface water. No news release was made for the incident. | | | | "On this basis, this notification is being retracted." | | | | The licensee notified the NRC Resident Inspector.

As a result, operators began to | | decrease load at 0036 on 05/18/99 with the unit at approximately 83% reactor | | power. Operators manually tripped the reactor from 73% power at 0041. At | | that time of the manual reactor trip, vibrations on the #1 and #2 bearings | | were at a level of about 10� mills and 12 mils, respectively. The limits on | | vibration are either 10 mils for 15 minutes or when a vibration of 12 mils | | is reached. | | | | All control rods fully inserted as a result of the manual reactor trip, and | | all systems functioned as required. There were no engineered safety feature | | actuations or emergency core cooling system injections, and none were | | required. | | | | The unit is currently stable in Mode 3 (Hot Standby). The reactor coolant | | pumps, normal charging and letdown, and pressurizer heaters and sprays are | | being utilized for primary system transport, level, and pressure control. | | All containment parameters are normal. Emergency feedwater was manually | | initiated and is currently supplying water to the steam generators. | | Secondary steam is being dumped to the condenser. Offsite power is | | available, and the emergency diesel generators and emergency core cooling | | systems are operable and available if needed. | | | | The licensee notified the NRC resident inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 35730 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: HOPE CREEK REGION: 1 |NOTIFICATION DATE: 05/18/1999| | UNIT: [1] [] [] STATE: NJ |NOTIFICATION TIME: 12:24[EDT]| | RXTYPE: [1] GE-4 |EVENT DATE: 05/18/1999| +------------------------------------------------+EVENT TIME: 09:07[EDT]| | NRC NOTIFIED BY: ART BREADY |LAST UPDATE DATE: 05/18/1999| | HQ OPS OFFICER: STEVE SANDIN +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: |JIM TRAPP 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 | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | Primary Containment Isolation Signal (PCIS) unexpectedly generated during | | planned maintenance on the "B" channel Radiation Monitoring System. | | | | "While de-energizing the 'B' channel Radiation Monitoring System (RMS) to | | replace a power supply, an unexpected 'B' channel actuation of the Primary | | Containment Isolation System (PCIS, an ESF system) | | occurred. The single channel actuation resulted in isolation of three | | Containment Isolation Valves, electrical load shedding of two non-1E | | ventilation fans, and automatic starts of the 'B' channel Filtration | | Recirculation and Ventilation (FRVS) fans and Safety Auxiliaries Cooling | | Pump (SACS). All isolations and actuations occurred as designed. The power | | supply was re-energized and plant systems and components restored. The | | impact on plant operation from this single channel PCIS actuation was | | minimal. All plant safety systems remained capable of performing their | | required functions, except for the 'B' Switchgear Room Cooler which had been | | removed from service for scheduled maintenance. As a result of the change | | in Reactor Building pressure, the Reactor Building to Turbine Building steam | | tunnel blowout panel briefly indicated open, and is currently closed. A | | visual inspection of the blowout panel is in progress. | | | | "The initial investigation has determined that de-energizing the 'B' channel | | RMS power supply simulated high Reactor Building exhaust and Refueling Floor | | exhaust radiation signals from the three RMS channels which input into the | | 'B' PCIS channel. Investigation into the root cause of the single channel | | actuation is in progress." | | | | The licensee informed the NRC Resident Inspector and will inform local | | authorities (LAC Township). | | | | * * * UPDATE 1453 EDT ON 5/18/99 FROM BREADY TO S. SANDIN * * * | | | | The licensee has completed the visual inspection of the blowout panel with | | no abnormalities noted. The licensee will inform the NRC Resident | | Inspector.
