This report decribes the development of multi-array type probe for FBR steamgenerator tube. We studied integration between three kinds of probes, which were for axial flaw, for circumferential flaw and for wall thickness flaw, detecting method of accuracy locating probe and basic composition of multi-channel detector. It was comfirmed that each devices had object performance in performance test. We shall use this results to study design and manufacture of ultrasonic testing equipment for steamgenerator of FBR Monju.
