This new material is considered a permanent resolution of IGSCC in hold down beams by NUREG/0R-3052, and will eliminate the need to perform ultrasonic testing each outage.
Remote visual examinations were performed on twenty (20) jet pump inlet mixers.
Evidence of erosion was detected, but was deemed acceptable, o Ultrasonic thickness measurements were performed on selected components in the extraction steam and condensate /feedwater system piping per GPC's ongoing erosion / corrosion program, o Eddy current testing was performed on several feedwater heaters, the main generator stator water coolers, and the generator hydrogen
- coolers, o The core spray sparger and associated piping was visually examined per Cu11etin 80-13.
No reportable indications were detected, if you have any questions in this regard, please contact this office at any time.
