This paper describes the development of test fields for decommissioning works by remotely operated machines. Especially, prototypes that imitate penetrations for accessing inside of the Primary Containment Vessel were designed. Penetrations are the pipes; three types of penetration with different inner diameter are developed by referring to real size. Some elbow-type pipes are also prepared to configure various piping route. The prototypes and some peripheral facilities for testing the machines are described.
