| LOST SAFETY PARAMETER DISPLAY SYSTEM AND THE TECHNICAL SUPPORT CENTER |
| COMPUTER |
| |
| Power was lost to the Safety Parameter Display System (SPDS) and the |
| Technical Support Center (TSC) computer system at 0904 EDT on 9/12/99. The |
| bus supplying power to the battery charger for the SPDS and TSC computer was |
| lost when the supply breaker opened on a ground detection, on the |
| underground cable supply. The normal alternate power supply to the battery |
| charger was previously lost, some time ago, due to another ground on its |
| underground cable supply. The licensee made the decision to preserve the |
| battery and deenergized the battery bus. Also, with the TSC computer system |
| out-of-service, the control room will serve as the alternate TSC facility. |
| |
| This event is a major loss of emergency assessment capability and is |
| reportable. Troubleshooting and repairs to the electrical distribution |
| system are in progress. Also, the licensee is investigating an alternate |
| methods to power the battery charger. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| |
| ***Update on 09/15/99 at 1255ET by Kemp taken by MacKinnon*** |
| |
| Power was restored to the TSC and the SPDS was restored to service at 1132ET |
| today (09/15/99). R2DO (Chris Christensen) notified. |
| |
| The NRC Resident Inspector will be informed by the licensee of this update. |

| |
| The licensee entered an Unusual Event per Emergency Action Level 2.1 Section |
| 14.1.2. All emergency diesel generators and their emergency core cooling |
| systems are fully operable. The electrical grid is stable. The licensee said |
| that they would have to enter Abnormal Operating Procedure 13 two hours |
| before wind speed increased to 75 mph. The licensee projects that they have |
| 27 hours until hurricane force winds reach their site. |

| OFFSITE NOTIFICATION DUE TO OPENING STORM DRAIN BYPASS VALVES |
| |
| On September 15, 1999, at 0935 EDT, the bypass valves from the site's storm |
| drain basin directly to the circulating water discharge canal were opened to |
| prevent site flooding (which could cause significant damage to plant |
| equipment and/or possibly endanger personnel safety) due to the impending |
| arrival of hurricane Floyd. Past experience has shown that the installed |
| pump capacity will not keep up with the rain expected during a hurricane. |
| The valves were opened prior to hurricane force winds reaching the site to |
| avoid exposing personnel to the hurricane. Opening these valves is a |
| reportable event (to the state of North Carolina) in accordance with the |
| site National Pollutant Discharge Elimination System permit. |
| |
| The NRC resident has been notified. |

| PATIENT RECEIVED A PLACEBO INSTEAD OF 20 GRAY OF P-32. |
| |
| A patient signed a consent form to participate in a coronary brachytherapy |
| trial to evaluate the Guidant Coronary Afterloader. The patient was |
| randomized to receive 20 Gray to the proximal left anterior descending |
| coronary artery with P-32, but the Radiation Oncology physicist programmed |
| the afterloader to use the placebo source wire instead. Therefore, the |
| patient did not receive the prescribed dose of 20 Gray. The root cause for |
| the error was that the Radiation Oncologist did not adequately confirm the |
| written directive prior to treatment. There was no documentation on the |
| randomization order to guide the physicist in selecting the proper |
| treatment, so he relied on his memory, which failed. |

| UNUSUAL EVENT DECLARED DUE TO APPROACHING HURRICANE |
| |
| An Unusual Event was declared at 2200 EDT due to the expected onset of |
| hurricane force winds within the following 12 hours. The licensee currently |
| expects that hurricane force winds will occur onsite at 1000 EDT. Both units |
| are currently being shut down in anticipation of the hurricane arrival. |
| Shutdown of Unit 2 commenced at 1906 EDT, and Unit 1 began shutting down at |

| |
| * * * UPDATE 0210EDT ON 9/16/99 FROM DALE JONES TO S. SANDIN * * * |

| REACTOR MANUALLY SCRAMMED FROM 52% REACTOR POWER DUE TO AN UNCONTROLLABLE |
| LOSS OF ELECTROHYDRAULIC CONTROL (EHC) FLUID. |
| |
| |
| At approximately 1750 on 09/15/99, failure of an EHC system pressure sensing |
| line resulted in an uncontrollable loss of EHC fluid. Attempts to maintain |
| EHC reservoir level failed, and a 1825 hours, the reactor was manually |
| scrammed from 52% reactor power in preparation for removing the EHC system |
| from service. Reactor power was initially at 100% and it was reduced to 52% |
| before the reactor was manually scrammed. The scram resulted in a low |
| reactor vessel water level, causing an automatic isolation of Primary |
| Containment Isolation System (PCIS) groups 2 (Drywell isolations), 3 |
| (Reactor Water Cleanup trip/isolation), &8 (transversing incore probe system |
| isolation). EOI-1 was entered due to low reactor vessel water level |
| {decreased to negative 28.5", Top of Active Fuel (TAF) is negative 162"} and |
| to control reactor pressure with the loss of the EHC system. No Main Steam |
| Safety Relief Valves (MSRVs) were actuated during this event. All control |
| rods fully inserted into the core. |
| |
| The licensee started that restart is projected for 1600 hours on 09/16/99. |
| |
| |
| NRC Region 2 Section Chief (Paul Fredrickson) was notified of this event by |
| the licensee. |

| PARTIAL LOSS OF EMERGENCY SIREN CAPABILITY DURING HURRICANE FLOYD |
| |
| "[Operations was] informed by Brunswick Plant Emergency Preparedness |
| personnel that 13 emergency warning offsite sirens have failed as a result |
| of Hurricane Floyd. |
| |
| "[The initial safety significance evaluation characterized the significance |
| of the loss of the sirens as] minimal. Backup alert measures are in place. |
| Local agencies have been notified. |
| |
| "[Corrective action(s) include a] complete investigation into the cause of |
| the failure and complete required repairs." |
| |
| The thirteen [13] sirens are located primarily on the beach and on Bald Head |
| Island and Boiling Spring Lake in Brunswick county. There are an |
| additional seventeen [17] operable sirens currently available in Brunswick |
| county and five [5] more in New Hanover county. The loss of the 13 sirens |
| was related to loss of power as detected by an external operability check |
| performed by a computer. The licensee will not initiate repairs until the |
| storm passes. |
| |
| The licensee informed state/local agencies and the NRC Resident Inspector. |

| - Secondary containment integrity lost due to a hatch cover being removed |
| during maintenance activities - |
| |
| At 0115 on 09/16/99. Limerick Generating Station Unit 2 experienced a loss |
| of secondary containment integrity. At the time of the event. the Standby |
| Gas Treatment (SBGT) System was in service. The Reactor Enclosure HVAC |
| System was not in service due to maintenance activities. The SBGT System was |
| unable to maintain reactor enclosure pressure greater than 0.25 inches of |
| vacuum water gauge per Technical Specifications due to a hatch cover being |
| removed for maintenance inspection activities. This event could have |
| prevented the fulfillment of the safety function of structures or systems |
| that are needed to control the release of radioactive materials or mitigate |
| the consequences of an accident. The hatch cover was reinstalled properly |
| by 0126 and the SBGT System was able to draw a vacuum on the reactor |
| enclosure area greater than 0.25 inches of vacuum water gauge. |
| |
| The licensee informed the NRC Resident Inspector. |
