To whom it may concern:

In pursuance of compliance to Federal Regulation 10CFR21, this letter is issued to provide an amendment for notification issued on June 24, 2022 of the potential defect in a configuration of the 11/2 Inch Quick Disconnect Connector cable assemblies supplied to Duke Energy (See attached spreadsheet) for a total of 460 of connectors only supplied to Oconee, McGuire and Catawba Nuclear Power Stations. This increase of scope is due to new evidence provided by Duke Energy, where this potential defect was found in other lots of material other than the ones previously bound to this condition.

The nature of the defect is a sharp edge located inside of the supplied reducing bushing which could cause damage to the cables when being installed or removed. These cable assemblies and bushing need to be evaluated to determine if this potential defect has occurred or if there is a potential for damage to occur at the earliest convenience. To the best knowledge of the application, we believe that there is a very low risk of damage to the cable assemblies after installation but this needs to be evaluated at the plants. We have been working with Duke Energy and will continue to support them until this issue is resolved.

To prevent this from reoccurring, Curtiss-Wright will implement inspection activities to verify the absence of burrs and/or sharp edges of all fittings that could potentially cause damage and prevent the items from performing its intended safety function.

For additional information, please contact Jim Tumlinson, Director of Operation (256-425-8037) or Christopher Covan, Quality Assurance Manager (256-624-7301), or Tim Franchuk, Director of Quality (513-201-2176).
