Inspection of the Steam Generator Divider Plate

Abstract

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.

Remote Sensing of Radiation Dose Rate by a Robot for Outdoor Usage

“…In hazardous environments robots used have been studied for nuclear industry and disaster relief, military usage for long time, especially robots have been actually used for many purposes in nuclear industries [1]- [3]. The most famous robot in the fields of military and disaster relief is "PackBot" manufactured by iRobot Co. more than 3000 units in Iraq and Afghanistan [4].…”
