| AT 1115 ON 04/19/99, THE LICENSEE NOTIFIED THE NEW YORK STATE DEPARTMENT OF  |
| ENVIRONMENTAL CONSERVATION THAT APPROXIMATELY 11 GALLONS OF HYDRAULIC OIL    |
| HAD SPILLED ON PAVED AND UNPAVED AREAS FROM A RUPTURED FORKLIFT HYDRAULIC    |

| 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.                    |
|                                                                              |

| MANUAL REACTOR TRIP FROM 73% POWER DUE TO UNEXPECTED HIGH  MAIN TURBINE      |
| VIBRATION                                                                    |

| While the licensee was in the process of increasing load after exiting a     |
| refueling outage, vibrations on the #1 and #2 bearings for the main turbine  |
| were noted to be increasing unexpectedly.  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.                                |
|                                                                              |

| 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."                                                   |

| Unit 2 was manually scrammed following the unexpected trip of the "A" recirc |
| pump.  At the time, electrical maintenance was in progress on the respective |
| motor-generator set.  Following the recirc pump trip, operators initiated a  |
| manual scram per procedure based on power-to-flow criteria.  There was no    |
| power peaking observed.  All control rods fully inserted.  Unit 2 is         |
| currently in hot shutdown with steam bleed to the main condenser for decay   |
| heat removal.  All systems functioned as required.  Both the traverse incore |
| probes and the recirc sump isolated during the transient as expected.        |
| Offsite power is available and the emergency diesel generators are in        |
| standby.  The licensee informed the NRC Resident Inspector.                  |

| "On 5/18/99 at 17:08, operators inserted a manual reactor scram due to       |

| "Preliminary investigation determined that while performing routine field    |
| brush maintenance, a ground occurred tripping the 'A' Recirculation Pump.    |
| The subsequent reactor power and flow decrease placed the reactor in the     |
