[en] The CEA Association is involved, in close collaboration with ENEA, FZK, IPP and UKEA European Associations, in the first ITER neutral beam injector and the ITER neutral beam test facility design (NBTF). A total power of about 50 MW will have to be removed in steady state on the neutral beam test facility (NBTF). The main purpose of this task is to make progress with the detailed design of the first ITER NB injector and to start the conceptual design of the ITER NBTF. The general infrastructure layout of a generic site for the NBTF, includes the test facility itself equipped of a dedicated beamline vessel and integration studies of associated auxiliaries as cooling plant, cryo-plant and fore-pumping system. The general infrastructure and auxiliaries layout of the NBTF are described. (authors)
