The DTT device: Safety, fuelling and auxiliary system

Abstract Apparently miscellanea of arguments are discussed in this paper but nevertheless all them are strictly related to safety of the DTT project. DTT should operate integrating all the reactor relevant physics and technology features, e.g. significant power loads, flexible divertors, plasma edge and core conditions approaching those of DEMO. The licensing process is discussed in the framework of the Italian law for which DTT will be classified as a radiogenic machine of category A. The guidelines for neutronics, fueling and pumping issues are highlighted. Finally, the cooling systems and the cryostat project are also illustrated.
