| LOSS OF CONTAINMENT INTEGRITY INVOLVING PERSONNEL AIRLOCK INTERLOCK FAILURE |
| |
| "On 23 January 2001, at 1510 hours, during the removal of radiation survey |
| equipment from the lower containment personnel airlock, the airlock doors |
| interlock failed. This allowed the inadvertent opening of both containment |
| airlock doors at the same time for less than one minute. This resulted in a |
| short entry into Technical Specification 3.6.1.1, for Primary Containment |
| integrity and entry into Technical Specification 3.6.1.3, for inoperable |
| Containment Airlock Doors. There was no radioactive release as the result of |
| this event." |
| |
| The cause of the interlock failure is under investigation. Currently the |
| licensee is controlling entry administratively. The licensee informed the |
| NRC resident inspector. |
