The status of the ITER design is as presented in the Interim Design Re
port accepted by the ITER council for considerations by ITER parties.
Physical and technical parameters of the machine, conditions of operat
ion of main nuclear systems, corresponding design and material choices
are described, with conventional materials selected. To fully utilize
the safety and economical potential of fusion advanced materials are
necessary. ITER shall and can be built with materials already availabl
e. The ITER project and advanced fusion material developments can proc
eed in parallel. The role of ITER is to establish (experimentally) req
uirements to these materials and to provide a test bed for their final
qualification in fusion reactor environment. To achieve this goal, th
e first wall/blanket modules test program is foreseen.
