The following report was received via fax:
The SC [South Carolina] Department of Health and Environmental Control was notified in writing on January 25, 2012, that during a routine shutter check, a Vega Americas Corporation Model SHRD gauging device containing 20 Ci of Cs-137, had a shutter mechanism that was harder to operate than normal. Vega Americas Corporation was contacted and on January 24, 2012, a Vega Americas Corporation technician arrived and was evaluating the operation of the shutter when it failed in the closed position. The metal operating handle broke off and the shutter cannot be moved. The source holder was surveyed and [it was] verified that the shutter is in the closed and safe position.
Following further correspondence with the licensee on May 1, 2012, the licensee stated that Vega Americas Corporation will not repair the source holder. Vega Americas Corporation will be handling the proper disposal of the SHRD fixed gauge.
Even though this event is being reported, the Department of Health and Environmental Control does not feel that this is a reportable event since the shutter is closed and radiation exposure in excess of regulatory limits is not possible.
