August 26, 2022 To whom it may concern:

In pursuance of compliance to Federal Regulation 10CFR21, this letter is issued to provide closure for notification issued June 24, 2022 of the potential defect in a configuration of the 1 1/2 Inch Quick Disconnect Connector (P/N: 913602-111) cable assemblies supplied to Duke Energy under procurement documents 30129014, 03121479, 03114993 and 03124438 for a total of 19 connectors at the McGuire and Catawba Nuclear Power Stations. We have a high degree of confidence that this is limited to these supply of cables.

Of the 19 connectors, 11 have been returned to Curtiss-Wright and have been confirmed to have the suspected defect. Curtiss-Wright will be working with Duke Energy to have these connector assemblies replaced. Due to the nature of the defect and installation routines of the plant, for items installed at Duke Energy we have reasonable assurance that these connectors do not pose an immediate safety risk but could cause damaged during routine maintenance associated with the connectors and should be replace at earliest convenience.

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

For additional information, please contact Jim Tumlinson, Director of Operations (256-425-8037),

Christopher Covan, Quality Assurance Manager (256-624-7301), or Tim Franchuk Director of Quality (513-201-2176). ,....---* '\ -------/
