The inspection of the steam generator divider plate becomes more and more important since indications have been detected in some steam generators in the area of the welds between tube sheet and divider plate. Remote operated manipulator and tools have been developed in order to minimize the radiation exposure of the personnel performing the inspections. Inspection techniques based on liquid penetrant, visual inspections have been developed and qualified to detect the indications. An ultrasonic inspection technique to determine the depth of the indications has been developed and qualified. The aim of this paper is to describe the inspection capabilities available to support the partition plate inspections.
