| MISSING RADIOGRAPHY CAMERA CONTAINING AN IRIDIUM-192 RADIOACTIVE SOURCE      |

| "A Department inspector in the W. Chicago Regional Office, took a call ago   |
| from the  RSO of Conam Inspection Inc. (lL-01225-22) in Glendale Heights,    |
| IL.  The RSO reported that a radiography camera [Model 660-B, S/N B2872]     |
| containing 86 Ci [Curies] of Ir-192 [Iridium-192], as of March 20, 2003,     |
| destined for the Sequoyah Power Plant  in Soddy Daisy, Tennessee had failed  |
| to arrive as of the expected delivery date 3/17/2003.  He further stated     |
| that the carrier has been contacted daily since 3/18/03 for information as   |
| to the package's whereabouts with no success.   As of 1515 hrs. on 3/20/03,  |
| the carrier indicated to him that the package may have been misrouted and    |
| can only confirm the package leaving a sorting facility in Lisle, Illinois   |
| with potential stops in South Bend, Indiana and the carrier's hazmat center  |
| in Wilmington, Ohio.  The RSO was advised that a thorough search was being   |
| conducted by the carrier's  personnel.                                       |
|                                                                              |
| "The RSO  is sensitive to the current security issues and wanted to ensure   |
| the situation was promptly reported and to indicate some extent of           |
| frustration with the carrier although he hoped that the carrier would indeed |
| locate the package.  The package is in a black AEA Technology [Model 424-9,  |
| Sealed Source] overpack box marked with S/N 853 and labeled as a 'Yellow     |
| II.' The RSO provided a copy of the shipping paper that included the         |
| specific information concerning  the radiography camera, the package         |
| tracking number, and a contact number at the carrier.  The  department used  |
| this information and made direct contact with the carrier.  Carrier          |
| confirmed the above information and is continuing their search.  In fact,    |
| the carrier reported this event to the NRC Operations Center as did NRC      |
| Region II."                                                                  |

|                                                                              |
| "On 21 March departmental inspectors proceeded to the Lisle, Illinois        |
| Airborne Express distribution facility to survey the area to try and locate  |
| the device.  At approximately 0930 on 21 March [DELETED], Conam, notified    |
| the department that the camera was located by Airborne Express at one of     |
| their facilities in Springdale, South Carolina.  The camera will be          |
| transported to its original destination at Soddy Daisy, TN.  Upon learning   |
| this information, the departmental inspectors immediately terminated their   |
| survey of the Lisle Airborne Express facility.  The problem appeared to be a |
| failure to follow the appropriate procedure by Airborne Express for their    |
| hazmat packages.  The Airborne Express procedures are adequate and are       |
| routinely used effectively but for this package they made an error that      |
| resulted in the hazmat package being sent to their standard package          |
| processing facility in Atlanta and subsequently inadvertently sent to        |
| Springdale, SC.  Airborne Express is reviewing possible actions to prevent   |
| recurrence.  NRC was notified by phone and email that the camera had been    |
| located.  The event was assigned event number 39684."                        |

| At 1044 CST, on 3-23-03 the Plant shift Superintendent (PSS) was notified    |
| that the control power for C-337A  Autoclaves 1 East and 1 West was          |
| interrupted due to a fuse smoking in the distribution panel.  The power      |
| supply for the local autoclave area audible and visual alarms for the UPS    |
| Release Detection System are fed from the #1 Autoclave control power.  Due   |
| to the loss of control power to the #1 Autoclaves, the UF6 Release Detection |
| System was rendered inoperable.   At the time of this incident, the C-337A   |
| facility was in an operational mode in which the UPS Release Detection       |
| System was required to be operable.  The system was declared inoperable and  |
| Limiting Conditions for Operation (LCO) required actions were put in place   |
| until power could be restored.  Power was restored and the UF6 Release       |
| Detection System was declared operable at 1206 on 3-23-03.                   |
|                                                                              |
| The event is reportable as a 24 hour event, as required by 10 CFR            |
| 76.120(c)(2)(1):  "An event in which equipment is disabled or fails to       |
| function as designed when the equipment is required by TSR to prevent        |
| releases, prevent exposures to radiation and radioactive materials exceeding |
| specified limits, mitigate the consequences of an accident, or restore this  |
| facility to a preestablished safe condition after an accident."  The         |
| equipment was required by TSR to be available and operable and no redundant  |
| equipment was available to perform the required safety function.             |
|                                                                              |

| A package containing technetium - 99m delivered by Syncore (Cardinal Health) |
| of Columbia SC, to Moncrif Army Community Hospital was found to have surface |
| contamination levels of 21,000 dpm on its exterior.  The package was opened  |
| and it was verified that the metal container was not internally              |
| contaminated.  The ammo box was placed in a store room to decay.  The five   |
| (5) capsules containing technetium - 99m were used by the Hospital.  The RSO |
| called the vendor and informed them of the surface contamination found on    |
| the outside of the package.  The RSO will survey the path traveled through   |
| the Hospital by the vendor carrying the package to ensure the absence of     |
| loose contamination. The RSO will contact the vendor to verify if they had   |
| contamination issues with other shipments.                                   |

| Although the total mass of the grouped items was not independently verified  |
| to be less than a safe mass, no single pallet contains greater than 35       |
| pounds of uranium. The highest enrichment of any item was 2.0 wt. % 235U.    |
| The safe mass for uranium at 2.0 wt. % 235U is approximately 250 pounds.     |
|                                                                              |

| In order for a criticality to be possible, greater than a safe mass of       |
| uranium must be accumulated and then become moderated.                       |
|                                                                              |

| No single pallet has greater than 35 pounds of uranium and the highest assay |

| The first leg of double contingency is based on mass. NCSA GEN-010 requires  |
| that the total uranium mass of grouped items be verified less than the UH    |
| [Uncomplicated Handling] mass limit and documented. No documentation exists  |
| that substantiates that this verification was performed; therefore, this     |
| control was violated. However, since none of the groups contain greater than |
| a safe mass this parameter was not exceeded.                                 |
|                                                                              |
| The second leg of double contingency is based on mass. NCSA GEN-010 requires |
| that the total uranium mass of grouped items be independently verified less  |
| than the UH mass limit and documented in accordance with CP2-PO-FO1031. No   |
| documentation exists that substantiates that this independent verification   |
| was performed; therefore, this control was violated.                         |
|                                                                              |
| Even though the mass parameter was maintained, double contingency is based   |
| on two controls on mass. Since neither control was maintained, double        |
| contingency was not maintained.                                              |
|                                                                              |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEMS AND WHEN EACH WAS IMPLEMENTED:  |

| 1. Properly group and document each pallet according to CP2-CO-CN2030.       |
| 2. Upon completion of corrective action 1 for each of the 9 pallets, the     |
| exclusion zone and postings may be removed.                                  |
