The following is a synopsis of information provided by Curtiss-Wright via email:
On January 7, 2025, Rosemount notified Curtiss-Wright Middleburg Heights regarding Generation 3 quick disconnect connectors (QDCs) with no connection on at least one wire, with the bad connection not favoring one specific wire. Rosemount identified five Generation 3 QDCs out of 122 tested, where the issue is specifically in the continuity of the wires. All Generation 3 QDCs from the order are currently on hold at Rosemount and have not been shipped to any customer.
On January 9, 2025, Rosemount sent Curtiss-Wright two of the five questionable Generation 3 QDCs. Curtiss-Wright performed an initial evaluation to confirm the issue. The results were initially confirmed, but with minor manipulation the Generation 3 QDCs no longer showed negative results. Curtiss-Wright and Rosemount have agreed to send all the questionable Generation 3 QDCs to an outside testing entity to help perform a failure analysis to assist in determining the root cause.
Curtiss-Wright anticipates completing the evaluation by Tuesday, May 6, 2025.
There are no known plants affected.

Curtiss-Wright has completed their evaluation of the deviation described in their interim report submitted to the NRC on March 12, 2025. Curtiss-Wright concluded that the deviation does not constitute a reportable defect. The occurrence was isolated to the Generation 3 quick disconnect connectors (QDCs) provided to Rosemount on a specific order. All questionable Generation 3 QDCs have been scrapped by Rosemount and were not provided to any utility.
