EVENT TEXT
+------------------------------------------------------------------------------+
| AUTOMATIC REACTOR TRIP DUE TO A GENERATOR LOCKOUT FOR UNKNOWN REASONS |
| |
| At 1956 on 08/18/99, Oconee Unit 1 automatically tripped from 100% power, |
| and the cause of the trip is currently under investigation. At this time, |
| the licensee believes that an electrical generator lockout (for unknown |
| reasons) cause a turbine trip and subsequent reactor trip. Post-trip |
| response was normal. All control rods fully inserted. There were no |
| emergency core cooling system or engineered safety feature actuations, and |
| none were required. The main steam safety valves lifted and reseated as |
| expected. There were no maintenance or surveillance activities occurring at |
| the time of the generator lockout. There were no storms in the area, and |
| the weather was stable and hot. All systems functioned as required, and the |
| cause of the generator lockout is the only thing that is not understood at |
| this time. |
| |
| The reactor is currently subcritical, and shutdown margin is within |
| technical specification limits. Reactor coolant system inventory control is |
| being provided via normal makeup. The power-operated relief valves and |
| pressurizer code safety valves are closed. Primary system transport is |
| being controlled by forced circulation via all four reactor coolant pumps. |
| Secondary steam is being dumped to the main condenser via the turbine bypass |
| valves, and main feedwater is supplying water to the steam generators. |
| |
| The licensee notified the NRC resident inspector. |
| |
| *** UPDATE AT 1242 EDT ON 8/20/99 FROM NICHOLSON TO POERTNER *** |
| |
| The original cause of the Oconee Unit 1 trip on 8/18/99 was believed to have |
| been an electrical generator lockout based on annunciation available at the |
| time. Subsequent evaluation has concluded that the trip was caused by an |
| internal voltage problem within the solid state programmer for the group 5 |
| control rods. This voltage anomaly caused the Group 5 rods to drop into the |
| core. The entire programmer has been replaced, with the defective equipment |
| being returned to the manufacturer for additional evaluation. |
| |
| The NRC resident inspector has been notified. |

| |
| "Date of Event: March 9, 1999." |
| |
| "Initial Report: Telephonic report March 10, 1999. (Lost)" |
| |
| "On the afternoon of March 9, 1999, a patient was loaded with a 51.25 mgRaeq |
| (127.35 millicurie Cesium-137) gynecological implant for a planned treatment |
| time of 44.77 hours. Late that evening the patient was discovered to have |
| removed the implant. The implant was discovered in the bed beside the |
| patient's hand/arm at hip level. Nursing staff removed the loading to the |
| far side of the room, placed a rolling lead shield between the source and |
| the patient, then notified the Gynecological physician on duty and the |
| Brachytherapy Services staff. Estimated treatment time was only about 8.833 |
| hours. This treatment time differed from the prescribed treatment dose by |
| more than 10%. The patient treatment was terminated without additional |
| treatment. The event was reported telephonically on the afternoon of March |
| 10, 1999. This message was never delivered to the proper authorities within |
| the Agency. An initial written report filed by the hospital stated that the |
| facility Radiation Safety Committee did not consider this a |
| misadministration but a refusal of treatment by the patient. The 10% rule |
| was considered by the Agency and a full report was filed by the hospital." |

| NRC BULLETIN 91-01, 24 HOUR REPORT |
| |
| At 1242 CDT on 8/20/99, the Plant Shift Superintendent was notified that |
| adjacent system post-removal Non-Destructive Assay (NDA) was not performed |
| as required by NCSA GEN-10 for the Unit 3, Cell 7, Stage 8B blowout |
| preventer actuator removed in the C-335 cascade building. The post-removal |
| NDA is required to be performed within 24 hours of the equipment being |
| removed. The post-removal NDA measurement is used to independently verify |
| the mass of any potential adjacent system deposit is less than an always |
| safe mass and can be characterized as Uncomplicated Handling (UH). The |
| pre-removal NDA indicated no significant deposit in the adjacent system. |
| |
| The post-removal NDA measurement was subsequently performed within 4 hours |
| of discovery which confirmed the adjacent system to be UH. |
| |
| This event is being categorized as a 24 hour event in accordance with Safety |
| Analysis Report Table 6.9-1, Criteria A.4.a and Bulletin 91-01, Supplement |
| 1. |

| MANUAL INITIATION OF HVAC CHLORINE ISOLATION MODE |
| |
| At 1645 EDT on 8/20/99 an equipment operator reported a faint smell of |
| chlorine in the Unit 2 reactor building (253 foot elevation). The floor |
| supervisor was dispatched to investigate. The main control room personnel |
| placed the Main Control Room (MCR) HVAC system in a chlorine isolation mode |
| as a planned conservative measure. No indication of chlorine was ever |
| present on the MCR HVAC chlorine detectors. The floor supervisor reported |
| that there was a slight, barely detectable, chlorine like odor in the area |
| but that it had dissipated. The MCR HVAC system was returned to the normal |
| mode of operation at 2304 EDT 8/20/99. There was no adverse impact to plant |
| operations. |
| |
| A subsequent review of the reportability requirements was made on 8/21/99 at |
| 1000 EDT and it was determined that a four hour report pursuant to |
| 50.72(b)(2)(ii) should be made for the manual initiation of a MCR chlorine |
| isolation. |

| technical specification allowable limit for degraded bus voltage settings |
| may not protect all safeguards loads from the effects of an undervoltage |
| condition under all accident conditions. A recent calculation has verified |
| that under certain plant conditions, the current degraded bus undervoltage |
| settings are below that required to insure proper operation of equipment |
| powered by our 600-volt safeguards buses. Safeguards loads on our 600-volt |
| buses consists primarily of valves and ventilation equipment." |
| |
| "Currently, both units are in a defueled condition. In the current mode, |
| the degraded bus voltage function is not required. Also, since the |
| safeguards buses are lightly loaded during shutdown conditions, the impact |
| due to low grid voltage is low. An operability determination has been |
| performed to demonstrate that the condition does not affect the operability |
| of the safeguards buses while the plant is in a shutdown condition." |
| |
| "Actions are in progress to correct the low degraded bus voltage settings as |
| well as the limit specified in technical specifications." |
| |
| The licensee notified the NRC resident inspector. |

| |
| On August 20, at 2358, a lightning strike caused a momentary loss of a 500kv |
| transmission line. The resulting electrical transient caused the trip of the |
| following equipment: "A" Reactor Feedpump, "A" Electrohydraulic Control |
| Pump, "A" and "B" Reactor Water Cleanup Pumps, "A" Technical Support Center |
| Chiller, "A" Control Room Chiller, "A" and "B" Main Reactor FeedpumpTurbine |
| Lube Oil Pumps, and the Drywell Coolers. The following equipment |
| automatically started: "B" Technical Support Center Chiller, "B" Control |
| Room Chiller, "B" Safety Auxiliaries Cooling System Pump and the "B" |
| Electrohydraulic Control Pump. The trip of the "A" Reactor Feed Pump and |
| the resulting lowering Reactor water level caused an automatic Reactor |
| Recirculation system runback to approximately 70% Reactor power. |
| |
| This equipment was restored to normal operating configuration, and Reactor |
| power was restored to 100% at 0449 on August 21,1999. At 0618, Station |
| Operators recognized that the #6 Feedwater Heater extraction Steam isolation |
| valves had automatically closed during the electrical transient. At that |
| time, final feedwater temperature was approximately 365 degrees Fahrenheit. |
| At 0646, a power reduction to 90% Reactor power was commenced and at 0826 |
| the #6 feedwater heaters were returned to service. |
| |
| Hope Creek Operating License Condition 2.C(11) states that the facility |
| shall not be operated with a feedwater heating capacity that would result in |
| a rated power feedwater temperature of less than 400 degrees Fahrenheit |
| unless analyses approving such operation are submitted by the licensee and |
| approved by the staff. Contrary to this license condition, the plant was |
| operated at rated power with feedwater temperature less than 400 degrees |
| Fahrenheit. |
| |
| The plant is currently operating at 100% Reactor power, with feedwater |
| temperature greater than 400 degrees Fahrenheit. The Hope Creek Staff is |
| currently reviewing Plant response to the electrical transient. All required |
| Safety systems are currently Operable and there are no active Limiting |
| Conditions for Operation in effect. |
| |
| The NRC resident inspector has been notified. |

| THE CRITICALITY ACCIDENT ALARM SYSTEM (CAAS) HORN DID NOT PASS TESTING |
| CRITERIA. |
| |
| At 1824 on 8/21/99, the Plant Shift Superintendent was notified that there |
| may be a problem with a specific model of CAAS horn. During testing of the |
| new CAAS system in C-746-Q. the 30 watt AC/DC CAAS horn did not pass the |
| testing criteria for horn actuation time. (Currently the new CAAS horns in |
| C-748-Q building are not inservice and the building is serviced by the old |
| System which does lot use these 30 watt AC/DC horns and remains operable) |
| ANSI/ANS 8.3 identities that the CAAS System shall automatically initiate an |
| evacuation alarm signal within one half second of the alarm setpoint being |
| exceeded. Preliminary testing Indicated that the 30 watt AC/DC CAAS horn |
| will not actuate in the required time frame (it takes 0.6 - 0.9 seconds). |
| The C-710 facility uses the 30 watt AC/DC CAAS horn in its current inservice |
| configuration. During the initial investigation of this event, it was |
| identified that when this type CAAS horn was installed in C-710, it was not |
| tested for response time, however the 15 watt AC horns which are also |
| installed in C-710 were tested within an acceptable time frame. At that |
| time, engineering did not suspect a deviation in horn activation response |
| time between the two different horn types. Since reasonable assurance of |
| operability is not maintained for the 30 watt AC/DC CAAS horn, the C-710 |
| building was declared inoperable at 1955 on 8/21/99. |
| |
| This event is reportable as "equipment is disabled and equipment Is required |
| by a TSR to be available and operable and no redundant equipment is |
| available and operable". |
| |
| Corrective actions have not yet been determined. |
| |
| The NRC resident inspector has been notified of this event. |
