|                                                                              |
| At 1500 on 06/02/99, it was determined that the mass control within a        |
| primary High Efficiency Particulate Air (HEPA) filter had been exceeded.     |
| This primary HEPA filter is on the combined exhaust of a utility hood and    |
| oxidation furnace.                                                           |
|                                                                              |
| Maintenance personnel discovered this situation in the Dry Scrap Recycle     |
| (DSR) facility during a routine inspection.  The hold-up weight was          |
| determined to be approximately 45 kgs U02 equivalent.  This exceeds the      |
| established mass limit of 25 kgs U02.  The second, independent control       |
| parameter on moderation remained intact, thus no unsafe condition existed.   |
|                                                                              |
| Associated equipment has been shutdown and controls were reestablished       |
| within 4 hours.                                                              |

| SAFETY SIGNIFICANCE OF EVENT:                                                |
| Low safety significance; independent controls on moderation remained intact. |
|                                                                              |
|                                                                              |
| POTENTIAL CRITICALITY PATHWAYS INVOLVE [BRIEF SCENARIO(S) OF HOW CRITICALITY |

| Multiple failure modes required before a criticality accident could occur.   |
| Simultaneous loss of moderation required.                                    |
|                                                                              |

| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL  (INCLUDE PROCESS    |
| LIMIT AND % WORST CASE CRITICAL MASS):                                       |
| 47 kgs U308 (~45 kgs U02 equivalent) at 4.1% U235 enrichment with maximum    |
| moisture content of 1,493 ppm H20.  Mass limited to 25 kgs U02 at 5% U235    |
| enrichment moderation limited to 50,000 ppm H20.  At 50,000 ppm H20, the     |
| safe hemisphere mass of theoretical density U02 exceeds 600 kgs U02 at 5%    |
| U235 enrichment                                                              |

| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION   |
| OF THE FAILURES OR DEFICIENCIES:                                             |
| Administrative control on differential pressure across HEPA filter housing   |
| failed.  Fuel business system computer controls limit feed material type to  |
| <50,000 ppm H2O equivalent.  Moderation control remained intact.             |
|                                                                              |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS IMPLEMENTED:  |
| 1. Shutdown of DSR oxidation furnace/utility hood operation; begin           |
| nondestructive assay gamma monitoring of DSR HVAC.                           |
| 2. Removal of prefilter & HEPA filter cartridge, shake U308 material down    |
| into safe geometry 3 gallon containers.                                      |
| 3. Investigation and implementation of corrective actions pending.           |
|                                                                              |
| This event is reportable pursuant to NRC Bulletin 91-01 (within 24 hours)    |
| due to the mass control failure.                                             |
|                                                                              |

|                                                                              |
| "On Tuesday, June 1, 1999, US Customs at Seattle-Tacoma International        |
| Airport detained a passenger whose luggage was detected to be radioactive.   |
| The alarm level was the highest on the US Customs meters.  The passenger was |
| determined to be a [World Health Organization (WHO)] physician in-bound from |
| Thailand on his way home to Alaska.   The physician admitted that he was     |
| bringing I-131 with him to his home in Alaska where he intended to treat his |
| cat for hyperthyroidism.  He did not have a license or any other             |
| authorization for the radioactive material.                                  |
|                                                                              |
| "US Customs contacted the emergency number for the Washington Department of  |
| Health, Division of Radiation Protection (WDOH).  During this initial        |
| contact, it was determined that the glass vial containing 4 to 6 millicuries |
| of  I-131 was being carried with NO SHIELDING and appeared to constitute a   |
| public health threat.   WDOH immediately asked the US Customs to seize the   |
| material under state law prohibiting possession of radioactive material      |
| without a license.   The pouch containing the vial was quickly isolated by   |
| US Customs, and staff from WDOH were dispatched.   The passenger was allowed |
| to continue home to Alaska.                                                  |

| THREE SPRINKLER SYSTEMS DECLARED INOPERABLE DUE TO CORRODED HEADS            |

| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent was notified that   |
| numerous sprinkler heads were corroded, affecting 16 sprinkler systems in    |
| C-337 and one system in C-333, such that the ability of the sprinklers to    |
| flow sufficient water was called into question.  Subsequently, these         |
| sprinkler systems were declared inoperable and TSR required actions          |
| establishing roving fire patrols were initiated.  This deficiency was        |
| detected during scheduled system inspections conducted by Fire Protection    |
| personnel.  Currently, functionality of the sprinkler heads has not been     |
| fully evaluated by Fire Protection personnel and the remaining cascade       |
| buildings are currently being inspected and if necessary this report will be |
| updated to identify any additional areas.                                    |
