| LOSS OF EMERGENCY SIRENS IN HARNETT COUNTY DUE TO A LIGHTNING STRIKE |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "All sirens in Harnett County were lost from 1600 to 1730 on 08/14/99 ... |
| due to a lightning strike [that took out a 911 repeater]. The backup |
| repeater was placed in service at 1730 [on 08/14/99]. The primary repeater |
| was placed in service at 1200 on 08/16/99. The backup repeater is not |
| tested routinely, and it is unknown if it would have actuated the sirens |
| from 1730 [on] 08/14/99 until 1200 [on] 08/16/99. This feature will be |
| tested tomorrow to determine if the sirens were operable on the backup |
| repeater." |
| |
| The licensee stated that there are a total of 81 sirens associated with the |
| Harris facility and that all 7 sirens in Harnett County were lost. This |
| event was determined to be reportable at 2040 on 08/16/99. |
| |
| The licensee plans to notify the NRC resident inspector. |

| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "A test signal was successfully transmitted to and received by the Harnett |
| County sirens on 08/17/99 at 0740 using the current configuration. This |
| test verifies that the siren system was operable when the primary repeater |
| was returned to service at 1200 on 08/16/99. No additional testing with the |
| backup repeater is planned." |
| |
| The licensee notified the NRC resident inspector. The NRC operations |
| officer notified the R2DO (Barr). |

| RELEASE OF CHLORINATED WATER TO STORM DRAIN AND OFFSITE NOTIFICATION |
| |
| The licensee discovered that, due to valve leakage, a small amount of |
| chlorine was released to a storm drain. The following information was |
| submitted to the NRC Operations Center by facsimile: |
| |
| "The service water backwash valve on strainer 'd' was experiencing severe |
| leakage past the valve. The system engineer estimated approximately 200 gpm |
| leakage occurred. During this time, the system chlorination evolution |
| occurred for 40 minutes. The forebay water was treated to a concentration of |
| 1 ppm. The result is that an estimated 0.067 lbs of chlorine was discharged |
| to the storm drain. The reportable quantity for chlorine is 10 lbs. There is |
| no reportability requirement for CERCLA; however, an NPDES noncompliance did |
| occur. Reportability is being investigated. The strainer valve has been |
| isolated to prevent it from operating until repairs are complete." |
| |
| This event is reportable to the NRC within 24 hours in accordance with |
| Section 4.1 of the site Environmental Protection Plan. In addition, the |
| licensee is notifying the US EPA of this release. The NRC resident inspector |
| has been informed of this notification. |

| MEDICAL MISADMINISTRATION |
| |
| A patient receiving an interstitial iridium-192 brachytherapy treatment was |
| implanted with eight ribbons containing Ir-192 seeds. At 1400 CDT on |
| 8/17/99, hospital personnel discovered that the patient had removed three of |
| the ribbons. The hospital is conducting an investigation to determine the |
| time when the ribbons were removed in order to determine the dosage |
| received. The licensee plans to contact the patient's attending physician. |
| |
| ****************** UPDATE AT 1528 EDT ON 08/18/99 FROM DOUGLAS SIMPKIN TO |
| TROCINE ***************** |
| |
| After reviewing this event and having discussions with NRC Region 3 (Daryl |
| Wiedeman), it was determined that this event was not a misadministration in |
| accordance with 10 CFR 35.33. The patient removed three of the ribbons, and |
| the analyzed dose does not meet the 20% threshold for misadministrations. |
| Therefore, the licensee is retracting this event notification. |
| |
| The patient's attending physician and radiation oncologist were both |
| contacted to discuss any medical ramifications, and it was determined that |
| there none. |
| |
| (Call the NRC Operations Center for a contact telephone number.) |
| |
| The NRC operations officer notified the R3DO (Clayton) and NMSS EO |
| (Piccone). |

| DISCOVERY OF AN OPEN FLOOR DRAIN VALVE WHICH MAY NOT HAVE PREVENTED CO2 FIRE |
| SUPPRESSION AGENT DISSIPATION IN THE EVENT OF A FIRE IN THE CABLE SPREADING |
| ROOM |
| |
| Hope Creek Operating License Condition 2.c(7) requires PSE&G to implement |
| and maintain in effect all provisions of the approved Fire Protection |
| Program as described in the Updated Final Safety Analysis Report (UFSAR) for |
| the facility through Amendment 15. One of those provisions (UFSAR Section |
| 9.5.1.1.9) requires the control equipment mezzanine floor drain isolation |
| valve to remain closed to prevent CO2 fire suppression agent dissipation. |
| Contrary to this requirement, the control equipment mezzanine floor drain |
| isolation valve was found open at 1253 on 08/17/99. This notification is |
| being made in accordance with License Condition 2.f because no provision had |
| been implemented to maintain the control equipment mezzanine floor drain |
| valve in the closed position. |
| |
| The control equipment mezzanine contains electrical and control power |
| cabling to and from the control room and remote control panels and |
| equipment. Had a fire occurred in this room with the control equipment |
| mezzanine floor drain valve open, the CO2 system may not have maintained the |
| minimum level of CO2 concentration necessary to extinguish the fire. |
| However, a manual water deluge system was also available to provide backup |
| to the CO2 system. Preliminary analysis indicates that the combination of |
| the remaining CO2 and water deluge would have precluded a fire postulated in |
| the control equipment mezzanine from impacting redundant safety-related |
| equipment. The remote shutdown panel remained available to achieve and |
| maintain the reactor in the shutdown condition remotely from the control |
| room. |
| |
| The control equipment mezzanine floor drain valve was closed at 1259 on |
| 08/17/99. The floor drain valves in the emergency diesel generator (EDG) |
| area and diesel fuel oil storage tank areas (which are identified in the |
| same UFSAR section) have been verified closed as required. The control |
| equipment mezzanine floor drain valve has been added to the tagging system |
| to ensure that it is controlled and maintained closed. Additional |
| investigation into the extent of the condition is ongoing. |
| |
| The 'D' EDG is currently inoperable with activities ongoing to clean one of |
| its two fuel oil storage tanks. The 'D' EDG remains available to start in |
| an emergency condition, and it has adequate fuel oil for 3 days of |
| operation. All other EDGs and safety-related equipment are operable at this |
| time. |
| |
| The licensee stated that it appears that the control equipment mezzanine |
| floor drain isolation valve had been open for an extended period of time |
| (possibly for the life of the plant). The licensee also stated that this |
| issue was identified by the NRC resident inspector during performance of an |
| assessment of the licensee's Fire Protection Program. |
| |
| NOTE: The valve is located in a 4" drain line. The control equipment |
| mezzanine floor drains are equipped with |
| drain traps. |
| |
| The licensee plans to notify the NRC resident inspector and the NRC Region 1 |
| office. |

| 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. |

| OFFSITE NOTIFICATION OF ONSITE CHEMICAL SPILL |
| |
| The licensee notified the Connecticut state Environmental Protection Agency |
| regarding an onsite spill of sodium hypochlorite. Approximately 50 gallons |
| of 50% sodium hypochlorite solution leaked from a barrel in the turbine |
| building. The licensee reported that the leakage has stopped, and that the |
| solution is flowing into floor drains which connect to an isolated sump (the |
| licensee has disabled pumpout capability). A hazardous materials contractor |
| has been retained to clean up the spill. The licensee plans to contact the |
| National Response Center regarding this event. |
