| FIRE DAMAGE TO EQUIPMENT CONTAINING RADIOACTIVE MATERIAL                     |
|                                                                              |
| On Wednesday December 9, 1998, at 0610 EST a motor fire occurred in the      |
| X-326 process building on cell 25-7-2.  The fire was put out by the plant    |
| fire department.  The fire involved lubricating oil in an electrical motor   |
| that drives compressors.  The fire was limited to a single housing           |
| containing the affected equipment.  However the fire spread to additional    |
| motors and equipment within the cell housing.  Damage to the equipment and   |
| piping caused the primary containment to be breached.                        |
|                                                                              |
| At 2245 EST the Plant Shift Superintendent determined that this event was    |
| reportable under 10CFR76.120(c)(4).  The fire damaged the radioactive        |
| material container (process gas piping) and the equipment contained          |
| radioactive material greater than 5 ALls (5 microcuries or 2.2 grams         |
| U-235).                                                                      |
|                                                                              |
| The certificate holder notified the NRC Resident Inspector, the local DOE    |
| representative, the state of Ohio, and issued a press release.               |
|                                                                              |

| SUBSEQUENT TO THE TERMINATION OF THIS EVENT ON 12/09/98, THE USEC HAS        |
| DETERMINED ON 6/11/99 @ 1502 THAT THIS EVENT MET THE CRITERIA FOR AN "ALERT" |
| EMERGENCY CLASSIFICATION.  THE DECLARATION OF AN ALERT WOULD HAVE BEEN       |
| REPORTABLE IN ACCORDANCE WITH 10CFR76.120(a)(4), BUT WAS NOT REPORTED AT THE |
| TIME OF THE EVENT BECAUSE AN "ALERT" WAS NOT DECLARED.  IN ACCORDANCE WITH   |
| THE GUIDANCE PROVIDED IN NUREG-1022, REV 1, USEC IS UPDATING THIS            |
| NOTIFICATION TO INDICATE THAT THIS EVENT ALSO MET 10CFR76.120(a)(4)          |
| REPORTING CRITERIA.                                                          |

| RADIOACTIVE THORIUM MAGNESIUM USAF AIRCRAFT PARTS FOUND IN SCRAPYARD         |
|                                                                              |
| At 0800 CST on 11/03/98, a C&C Alloy Company representative notified the     |
| Tinker Air Force Base (TAFB) Bioenvironmental Engineering Office (BEO) that  |
| aircraft parts they had purchased from the TAFB Defense Reutilization        |
| Management Office may be radioactive.  The BEO sent representatives to the   |
| C&C Alloy scrapyard in Oklahoma City to survey a crate of scrap metal which  |
| contained radioactive parts.  Radiation levels of the scrap metal were       |
| reading twice as much as background levels.  The metal had been cut up into  |
| small pieces and is believed to be magnesium thorium panels.  No personnel   |
| had been exposed to respirable particles during the cutting process.  The    |
| crate of material has been returned to TAFB for proper disposal.  The BEO    |
| plans to establish by 01/15/99 a procedure to survey scrap metal before it   |
| leaves TAFB.  The BEO plans to notify Oklahoma authorities and request that  |
| the Air Force Health Physics Branch (Brooks Air Force Base, San Antonio, TX) |
| provide a radiation survey team if C&C Alloy requests that a survey of their |
| scrapyard be performed.                                                      |
|                                                                              |
| The USAF Radioisotope Committee was informed of this event at 1300 CST on    |
| 12/16/98.                                                                    |

| C&C ALLOY RETURNED ALL RADIOACTIVE MATERIAL TO THE AIR FORCE AND DECLINED    |
| THE RADIATION SURVEY.  A GATE MONITOR WAS INSTALLED FOR THE DEFENSE          |
| REUTILIZATION MANAGEMENT OFFICE(DRMO) TO MONITOR ALL SCRAP METAL, AND PRIOR  |
| TO ITS INSTALLATION, SCRAP METAL WAS SURVEYED WITH HAND-HELD RADIATION       |
| DETECTORS.  PERSONNEL WILL BE EDUCATED ON THE USE OF THE GATE MONITOR.       |
|                                                                              |
| THE METAL WAS IDENTIFIED AS COMING FROM A T-53 GAS TURBINE ENGINE, POSSIBLY  |
| USED IN THE F MODEL UN-1 HELICOPTER.  THE MATERIAL WAS MANUFACTURED BY       |
| ALLIED SIGNAL AEROSPACE AND WAS IDENTIFIED AS CONTAINING 2 TO 3% BY WEIGHT   |
| OF THORIUM 232.  THIS ALLOY MEETS THE EXEMPT REQUIREMENTS OF                 |
| 10CFR40.13(c)(4).                                                            |

| DISCOVERY OF A MISSING CHEMICAL AGENT MONITOR CONTAINING 15 mCi OF NICKEL-63 |
| FROM SHAW AIR FORCE BASE LOCATED IN SUMTER, SOUTH CAROLINA                   |
|                                                                              |
| At 0938 on 05/07/99, Shaw Air Force Base (AFB) located in Sumter, South      |
| Carolina, notified the U.S. Air Force Radioisotope Committee located at      |
| Bolling AFB located in Washington D.C. of a missing chemical agent monitor   |
| (CAM) containing a 15-mCi nickel-63 source.                                  |
|                                                                              |
| On 04/27/99, the base radiation safety officer (RSO) at Shaw AFB conducted   |
| an inventory of CAMs located in building #1981.  The correct number of CAMs  |
| were there, but one had the wrong serial number.  Examination of previous    |
| inventories shows one CAM with a different serial number.  The building had  |
| been searched with no success.  The 20CES/CEX RSO has no explanation for the |
| different serial number on one CAM or where the correct CAM may be located.  |

| It is suspected that the CAM may have been exchanged with another Air Force  |
| Unit or may have been sent off for calibration.  At this time, the U.S. Air  |
| Force Radioisotope Committee believes that the CAM is still in Air Force     |
| possession.  Past shipping records will be researched, and calibration labs  |
| that serve Shaw AFB will be notified.  The completion time for these actions |
| is currently estimated to be 06/07/99.                                       |

| THE SITE REPORTED THAT AT 1345, OPERATIONS PERSONNEL DISCOVERED STANDING     |
| WATER UNDER AUTOCLAVE #6 IN THE X-343, FEED AND SAMPLING FACILITY.  STANDING |

| LOSS OF CRITICALITY ACCIDENT ALARM SYSTEM DURING MAINTENANCE                 |
|                                                                              |
| "At 1633 CDT on 6/10/99, electricians were performing scheduled maintenance  |
| on the C-400 building criticality accident alarm system (CAAS).  During this |
| maintenance activity, circuit breaker EP1 in C-400 was opened resulting in a |
| system trouble alarm on the C-409 building 'AE' CAAS cluster.  TSR LCO       |
| actions were implemented for the C-409 facility due to the unknown cause of  |
| the trouble alarm.  After further review of this maintenance activity, there |
| is evidence that control power for the CAAS building horns in C-409 and      |
| C-720-M was lost for approximately four hours during the subject maintenance |
| evolution.  CAAS detectability and C-409 local CAAS horn operability were    |
| not affected by the loss of control power.                                   |
|                                                                              |
| "It has been determined that this event is reportable under                  |
| 10CFR76.120(c)(2) as an event in which equipment is disabled or fails to     |
| function as designed.                                                        |

| A MANUAL REACTOR TRIP WAS INITIATED BECAUSE OF A LOSS OF CONDENSER VACUUM    |
| (CAUSE UNKNOWN AND BEING INVESTIGATED).  ALL RODS FULLY INSERTED, NO ECCS    |
| INJECTION INITIATED AND NO SAFETY OR RELIEF VALVES LIFTED.  AUXILIARY        |
