| Title | Part 21 - Potential Transducer Component Defect |
| Event Description | The following information was received via fax:
The ITT Conoflow models GT25CA1826 and GT25CD1826 current to pressure (l/P) transducers produce a calibrated 3.0 to 15.0 psi output pressure from a 4.0 to 20.0 mA DC (input) signal. On November 2, 2016, a discovery was made of unqualified electrical component substitutions on the internal circuit board. Supplier and internal record reviews indicate these unqualified components were used as early as May 10, 2013, as the previously qualified PCB components are no longer available. Environmental qualification of the suspect circuit boards is planned for early 2017. If any component falls to meet requirements, nuclear facilities which use this product will be advised to examine their product for unqualified printed circuit boards via notification and visual references. Qualified replacement components will be provided to all affected customers.

On November 2, 2016 a discovery was made of unqualified electrical component substitutions on the internal circuit board. Supplier and internal record reviews indicate these unqualified components were used as early as May 10, 2013, as the previously qualified PCB components are no longer available. Environmental qualification of test samples containing the suspect circuit boards has been completed. The subject parts continued to operate and perform their intended safety function throughout all EQ [Equipment Qualification] tests. Notified R1DO (DeFrancisco), R2DO (Bartley), R3DO (Jeffers), R4DO(Deese), NMSS Events Resource, and Part 21 Group via email. |
