Remote equipment or robotic systems have been developed and employed at many nuclear material handling sites.
A nuclear fuel cycle technology, which reuses spent nuclear fuel as a raw material, is being developed in the DFDF (DUPIC Fuel Development Facility) at KAERI (Korea Atomic Energy Research Institute).
The DFDF is the hot-cell of the IMEF (Irradiation Material Examination Facility) at KAERI.
The master-slave manipulators installed in the DFDF hot-cell and isolation room are used to handle materials or equipment located inside the cell.
