We have developed under sodium viewer for sodium-cooled fast reactor. In particular, the receiving sensor and the transmission sensor has been developed. In addition, we have aimed a proficiency of an acoustic technology under sodium. Moreover, imaging experiments in the water and the sodium were conducted using the developed transmission and the developed receiving sensor. In this study, we will explain the developmental status.
