This report is being submitted by Team Industrial Services, Inc. (TISI), as required by 10CFR Part 21. This report is to serve as notification of a nonconforming condition encountered by TISI, when using crank assemblies, manufactured or serviced by the supplier shown below, with Amersham-660B radiographic exposure devices.

An initial failure of these crank assemblies (s/n NDT-267) was noted by TISI personnel performing industrial radiography at a jobsite in Sewaren, NJ on 04/18/06. Specifically, the radiography crew was able to connect the drive cable assembly to the exposure device, without connecting the drive cable to the source connector. As a result, the radiography crew was unable to return the source assembly to the exposure device, and emergency source retrieval was required. Based on our understanding of the specifications established in ANSI N432-1981, section 6.1.4, these controls should not have allowed exposure of the source assembly if the drive cable was not properly connected.
Subsequent evaluation of other crank assemblies purchased from the supplier noted the same failure. As a result, all TISI branches have been directed to identify these assemblies as nonconforming and to remove them from service. A Supplier Corrective Action Request (SCAR) has been issued, per TISI's Quality Assurance Program, against this supplier as a result, requesting a determination of the root cause of this nonconformance, action to correct, and action to prevent recurrence.
