Abstract
This paper is based on the remote maintenance system
project (WPRM) for the demonstration fusion power reactor
(DEMO). Following ITER, DEMO aims to confirm the
capability of generating several hundred of MW of net
electricity by 2050. The main objective of these
activities is to develop an efficient and reliable remote
handling (RH) system for replacing the divertor
cassettes.This paper presents the preliminary results of
the concept design of the divertor RH system. The
proposed divertor mover is a hydraulic telescopic boom
driven from the transportation cask through the
maintenance tunnel of the reactor. The boom is divided in
three sections of 4. m each, and it is driving an
end-effector in order to perform the scheduled operations
of maintenance inside the vacuum vessel.Two alternative
design of the end effector to grip and manipulate the
divertor cassette are also presented in this work. Both
the concepts are hydraulically actuated, basing on the
ITER previous studies. The divertor cassette end-effector
consists of a lifting arm linked to the divertor mover, a
tilting plate, a cantilever arm and a hook-plate.The main
objective of this paper is to illustrate the feasibility
of DEMO divertor remote maintenance operations.
