The licensee, Duke Energy - Brunswick Nuclear Plant, evaluated the installed elbows for acceptability in accordance with their corrective action program. Brunswick inspectors performed UT thickness evaluations of the installed nonconforming elbows (Fitting IDs: 16836-1-3, -14, and -20) and the results were used to confirm that the subject system remained operable. The remaining six nonconforming elbows (Fitting IDs: 16836-1-1, -6, -7, -11, -15, and -21) have been returned to the manufacturer, Flowline, and are being processed and controlled under Flowline's nonconforming items program.
