Within the scope of the design and qualification of a helium-cooled lithium-lead (HCLL) blanket module for DEMO, test blanket modules (TBM), have to be designed and inserted in ITER for testing. Several different TBMs will be tested in order to achieve the different testing objectives, according to the ITER operating scenario. This paper aims at presenting the design status of the so-called "integral-TBM (IN-TBM)", which will include all main features of the corresponding DEMO blanket module, such as design architectures, Eurofer structural material, functional parameters, and all relevant manufacturing processes.
