| Federal Express informed the Massachusetts Department of Public Health RCP   |
| that the package is expected to arrive in Memphis, Tennessee, by tomorrow    |

| - Fuel Building inoperable due to loss of vacuum in Fuel Building due to an  |

|                                                                              |
| At 2151 CDT on 04/28/99, with the plant in Operational Condition  5 in a     |
| refueling outage, the Fuel Building was determined to be inoperable.  At the |
| time, fuel inspection activities were in progress in the Fuel Building.      |
|                                                                              |
| The Fuel Building was rendered inoperable when a Fuel Building/Annulus door  |
| was opened. The door was opened to allow entry of personnel for completion   |
| of required testing of lighting circuits. The control room staff was alerted |
| to this condition when the "Fuel Building Pressure High" alarm was received. |
| Upon receipt of the alarm, the Control Room Supervisor directed that fuel    |
| handling activities be suspended.  Fuel handling activities were immediately |
| suspended and not resumed until the door was closed to reestablish Fuel      |
| Building integrity.                                                          |
|                                                                              |
| The fuel inspection activities in progress consisted of removing single fuel |
| pins from an irradiated bundle.  The irradiated bundle was located in the    |
| fuel preparation machine.                                                    |
|                                                                              |
| The Fuel Building/Annulus door was required to be closed to maintain the     |
| leak tightness of the Fuel Building. Plant staff personnel are continuing to |
| evaluate this event.  However, as a result of the open door, the Fuel        |
| Building may not have been able to perform its design function.              |
|                                                                              |

| tags indicating less than 5 pounds of uranium were discovered in violation   |
| of NCSA GEN-10 two foot spacing requirement for UH pieces of equipment.      |
| These items were improperly categorized as spacing exempt based on the size  |
| criteria of having dimensions in all directions greater than that of a 5.5   |
| gallon drum. Fifty-three items would be required prior to exceeding the UH   |
| mass at 2.0 wt. % U235. Similar incidents involving the violation were also  |
| discovered in C-710, room 2. C-409, and C-720. GEN-l0 states that UH items   |

| Technical Specification 4.3.1.2 Surveillance Requirement for Reactor Trip    |
| System Response Time for the Power Range Low Set Point Trip for was          |
| performed during initial startup testing.  It has not been performed since   |
| 1975 on Unit 1 and 1984 on Unit 2.  This function is required to be operable |
| in Mode 2 and in Mode 1 below P-10 (10% power).  Each unit has been in Modes |
| 1 and 2 many times without a current response time test.  The next time each |
| unit goes below P-10, Technical Specification 4.0.3 Action will be applied   |
| (the surveillance will be performed).                                        |
|                                                                              |

| This discrepancy was discovered during an engineering department review of   |
