| At 0437 on 04/16/99, Bob Hayes of United Airlines notified the Department of |
| Transportation (DOT) National Response Center that a leaking container of    |
| radioactive solid sodium molybdate (DOT Yellow III) had spilled inside an    |
| aircraft that had landed at Newark International Airport (National Response  |
| Center Incident Report #480533).  Approximately 0.01 microcuries of material |
| had spilled.  The spill was cleaned up using an industrial cleaner, with no  |
| residual contamination detected.  LTJG Ebner of the National Response Center |
| notified the NRC Headquarters Operations Officer (HOO) and the NJ Department |
| of Environmental Protection (NJ DEP).                                        |
|                                                                              |
| At 0654 on 04/16/99, John Feney of the NJ DEP informed the NRC HOO that the  |
| container was a Tc-99m generator with a 15-curie radiation source and that   |
| he was preparing to respond to the airport.  He was conferenced with Region  |
| I (Dan Holody) and NMSS (John Surmeier and Fred Combs).  The generator was   |
| enroute from Amersham Holdings, Inc., located in Arlington Heights, IL, to   |
| Amersham Pharmacy located in Livingston, NJ.                                 |
|                                                                              |
| At 0721 on 04/16/99, John Marzocca of the Amersham Pharmacy located in       |
| Livingston, NJ, contacted the NRC HOO to provide additional information      |
| regarding the event.  He was conferenced with Region I (Dan Holody, George   |
| Pangburn, and Duncan White); Region III (John Jacobson); and NMSS (Fred      |
| Combs and John Surmeier).                                                    |
|                                                                              |
| At 0950 on 04/16/99, Joe Moon of Del-Med Trucking, Inc. (the package         |
| shipper), located in South Plainfield, NJ, notified the DOT National         |
| Response Center that the surface of the Type 'A' package measured 11,000 dpm |
| per 300 sq cm (0.0051 microcuries) upon arrival at the Amersham Pharmacy     |
| located in Livingston, NJ (National Response Center Incident Report          |
| #480547).  The exposed driver and the truck were recalled and                |
| decontaminated, and the aircraft has been impounded and is being             |
| decontaminated.   Mr. Winters of the National Response Center notified the   |
| NRC HOO and the NJ DEP.                                                      |

| containing 250 Ci of Am-241, had been misplaced between mid-December 1998   |
| and mid-January 1999.  The detectors were issued to the 324th Signal         |

| FAILURE OF A PRIMARY CONTAINMENT AIR SAMPLE RETURN ISOLATION VALVE TO MEET   |
| MAXIMUM INSERVICE TEST STROKE-TIME REQUIREMENTS                              |
|                                                                              |
| While performing quarterly valve stroke-time testing on Unit 3, a primary    |
| containment air sample return isolation valve exceeded its specified maximum |
| stroke-time limit.  The sample return line was isolated in accordance with   |
| Technical Specification 3.7.D for primary containment isolation valves, and  |
| this action satisfied the 4-hour limiting condition for operation action     |
| statement requirements.  The second in-line primary containment isolation    |
| system valve remains operable.                                               |
|                                                                              |
| The licensee stated that no other valves failed to meet the maximum          |
| stroke-time limits.  The licensee also stated that, during a test that was   |
| performed last month, the valve in question was identified as being in the   |
| 'Alert' time range for inservice test timing requirements and that it was    |
| being tested per the required increased testing frequency.  Corrective       |
| actions are being initiated, and troubleshooting activities are in           |
| progress.                                                                    |

| Generator already in Bypass per plant procedures.  This action requires the  |
| diesel be declared inoperable.  The action was immediately identified, and   |

| "At 1647 [CDT], on April 18, 1999, with the plant in Mode 5 (Refueling), the |
| High Pressure Core Spray [(HPCS)] Diesel Generator [(DG)] output breaker     |
| closed in response to an undervoltage condition on its safety-related        |
| 4.16-kV bus."                                                                |

| "At the time of the event, the HPCS DG was already running, unloaded, as     |
| part of a planned test sequence.  The undervoltage condition occurred when   |
| the normal supply breaker tripped open.  The HPCS DG output breaker operated |
| as designed, and the HPCS DG supplied its safety-related bus."               |
|                                                                              |
| "The HPCS system was inoperable when this event occurred and is not required |
