| Title | Fixed Gauge Shutter Unable to Close Due to Mechanical Failure |
| Event Description | On Friday, January 14, 2011 at approximately 1000 Hrs (EST) one of [the] facility Assistant RSO was advised that one of our devices was inoperable. This was due to a failure in the cable handle bracket mechanism, not the source itself. The handle that operates the cable that opens and closes the level indicator is held in place by a bracket that is mounted (bolted) to the side of the equipment. The lower lever pivot (hinge) bracket failed, probably due to age, resulting in an inability to operate the mechanism as designed. The radiation source is located between two Gas Recirculation Hoppers approximately 10-15 feet away.
The equipment has been tagged pending repair, and affected employees were notified. A manufacturer's authorized repair technician has been scheduled to make repairs on Thursday, January 20, 2011. Upon completion of repairs and after the device has been inspected and placed back in service [the licensee] shall notify [the NRC] in writing. Location: A Division of American Electric Power Rockport Plant Spencer County 2791 North US Hwy 231 Rockport, IN 47635 Isotopes: Cs-137 Quantities: 100mCi Chemical/Physical Form: Gas Recirculation Hopper Level Indicator Manufacturer: Texas Nuclear Device Model: 5197 Device Serial Number: LE/LX 5705 Source Serial Number: B2147 No personnel exposure or injuries sustained. |
