| AGREEMENT STATE REPORT - MEDICAL EVENT                                       |

| On 7/31/03, at approximately 1600 EDT, an Iotrex I-125 sealed source was     |

| administered to a brachytherapy patient to treat a brain tumor.  The sealed  |

| source contained 325 millicuries of I-125.  On 8/5/03 at 1148 EDT, upon      |

| removal of the sealed source from the patient, the hospital staff noted that |

| the amount of I-125 withdrawn from the patient was only 31.5 millicuries.    |

|                                                                              |

| The source is a liquid that is inserted into a balloon inside the patient's  |

| skull, then removed after a designated amount of time.  On 8/6/03, a         |

| manufacturer's representative from Proxima accompanied hospital staff to     |

| inspect the catheter and balloon that were used during this administration.  |

| The catheter and balloon were visually inspected and tested with a dye for   |

| leaks.  No leaks were apparent during either test.                           |

|                                                                              |

| The licensee did not report any immediate adverse affects on the patient.    |

| The referring physician was informed of this event.                          |

| "Unit 1/2 A and B Diesel Generators auto started on Undervoltage while       |

| attempting to transfer Shutdown Bus 1 to Alternate supply, the alternate     |

| supply breaker failed to close, resulting in a momentary undervoltage        |

| condition on the Shutdown Bus and 4160V Shutdown Boards A & B. Shutdown Bus  |

| 1 was reenergized by reclosure of the Normal feeder breaker. The Diesel      |

| Generators did not tie onto the board due to the voltage returned to normal  |

| prior to the DG obtaining rated speed and voltage when the operator reclosed |

| the normal supply breaker. SBGT [Standby Gas Treatment] & CREV [Control Room |

| Emergency Ventilation] auto started and Refuel Zone ventilation isolated due |

| to a failure of Unit 1 Refuel Zone Rad monitor; Unit 2 Reactor Zone          |

| ventilation isolated due to a momentary loss of I & C 'A'.                   |

| systems have been returned to a normal configuration with the exception of   |

| the shutdown bus "43 switch" [in normal supply]. All Emergency Diesel        |

| Generators are operable and in standby. Offsite electrical power supply to   |
