| 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.                                        |
|                                                                              |

| 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.                 |
|                                                                              |

| 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.                         |

| 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.                                           |

| 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.               |
