Abstract

This paper presents the state of the art in the field of remote assembly and maintenance, including system analysis design and operation for controlled fusion devices such as JET, and the future NET and ITER reactors. The operational constraints of fusion reactors with respect to temperature, radiation dose rates and cumulative dose are considered in relation to design requirements. Concepts such as articulated boom, in-vessel vehicle and blanket handling device are presented. A close relationship between computer simulations and experimental validation is necessary to ensure reliability in operation. Mockups and prototypes, in reduced and full scale, illustrate the progress in remote operations for fusion reactors. The developments achieved at the Institute for System Engineering and Informatics of the JRC, in the field of remote blanket maintenance, reliability assessment of RH systems and remote cut and welding of lips joints, are considered.
