Breeding Blanket Modules testing in ITER: An international program on the way to DEMO

Testing of Breeding Blanket Modules is one of ITERʹs primary objectives. This paper discusses the major features and requirements of key tests to be performed in ITER for several DEMO-relevant Test Blanket Modules as proposed by the present six ITER Parties. ntent is focused on the assessment work recently performed by the ITER Test Blanket Working Group mostly devoted to the establishment of a testing strategy, to the presentation of the Test Blanket Modules proposals and to the definition of the necessary interfaces with the ITER machine and buildings.
