| At 0124 EST on 3/06/2003, NRC Headquarters was contacted by State of WV      |

| Radiation Health Program that an automobile/truck accident had occurred in   |

| Parkersburg, West Virginia that involved a Iridium-192 radiography source.   |

| Local HazMat responders do not have radiation monitoring equipment.          |

| Currently, LLEA is in contact with Camden-Clark Hospital to obtain proper    |

| radiation monitoring equipment to determine if packaging is intact.  (It was |

| determined that Camden-Clark is unable to respond). Vehicle is located in    |

| local towing impound yard.  West Virginia will be responding in the morning  |

| to perform surveys.                                                          |

|                                                                              |

| The State of WV Radiation Health Program completed an inspection and         |

| radiation survey.   The Iridium-192 radiography source was found intact.     |

| Radiation levels were normal and there was no spread of radioactivity.  The  |

| radiography equipment was released to the licensee for transport back to the |

| work site where it was being used.                                           |

| PART 21 NOTIFICATION - AALBORG FLOW METERS                                   |

|                                                                              |

| Holtec International reports a potential defect in Aalborg model GFM671S     |

| mass flow rate meters.  The instruments are used to verify the correct       |

| amount of helium is backfilled into dry spent fuel storage canisters.  These |

| instruments were never used on a Holtec cask system containing spent nuclear |

| fuel because the problem was discovered during the preparatory phase before  |

| fuel loading.                                                                |

|                                                                              |

| Four meters were purchased for use at the Trojan nuclear plant to measure    |

| the amount of helium gas injected into a loaded Holtec dry spent fuel        |

| Multipurpose Canister (MPC).  It was determined that erroneous data was      |

| coming from the flow rate meters. It was determined by Aalborg that the      |

| published correction factors for helium/nitrogen were incorrect for this     |

| model flow meter.  At the time the discrepant condition was identified, none |

| of the flow meters had been used on an MPC loaded with spent fuel and they   |

| were subsequently removed from service until they could be correctly         |

| calibrated.                                                                  |

|                                                                              |

| Four flow rate meters were procured and delivered to the Trojan nuclear      |

| power plant. Three were not used in actual fuel loading activities due to    |

| the discovery of the mis-calibration during dry run activities.  The fourth  |

| flow rate meter has been removed from the site.                              |

|                                                                              |

| Aalborg is developing new helium correction factors.  In the interim, they   |

| have committed to using helium to calibrate all flow meters destined for use |

| in measuring helium.                                                         |

|                                                                              |

| Trojan plant was the first plant where flow rate meters and flow totalizers  |

| were to be used to confirm adequate helium backfill in Holtec MPCs loaded    |

| with spent fuel.  Therefore, no other Holtec client is affected for past     |

| loading operations. For future MPC loading operations, Holtec users, as well |

| as other purchasers and licensees are being notified via this report that    |

| Aalborg flow meters procured for use in important-to-safety activities may   |

| not be calibrated correctly and that certain catalogue correction factors    |

| have been determined to be incorrect.  The calibration of Aalborg flow       |

| meters should be confirmed prior to use in important-to-safety activities.   |
