- Prof. Francesco Romanelli is the President of the Divertor Tokamak Test (DTT) facility at ENEA Frascati Research Center. He has been working in nuclear fusion since 1980. He has led from 1996 to 2006 the ENEA activities in Physics of Magnetic Confinement Fusion. In 2006 he became Leader of JET, the largest magnetic fusion experiment in operation, and from 2009 to 2014 Leader of the European Fusion Development Agreement. In 2015 he moved to the University of Rome “Tor Vergata” where he is now professor of Physics of Nuclear Energy. He is also Editor in Chief of Nuclear Fusion, the largest impact factor fusion journal.

The Divertor Tokamak Test facility, is the largest magnetic confinement fusion facility under construction in Europe after ITER. Its mission is to investigate advanced solutions for the heat and particle exhaust in conditions relevant for ITER and DEMO.
DTT is a breakeven-class tokamak, fully superconducting to allow pulses of the order of 100s, with water cooled, tungsten plasma facing components capable of confining deuterium plasmas. Maximum plasma current of Ip = 5.5 MA and toroidal magnetic field of 6 T at the plasma center makes DTT in a position relevant for the present DEMO design. The effect of alpha particle heating will be mimicked by three auxiliary heating systems (ECRH 32MW 170GHz, ICRH 8MW 60-90MHz and negative ion beams 10MW 500keV). The maximum heating power to the plasma will be 45MW to reproduce the conditions expected in the ITER and DEMO divertor.
DTT has been designed as a flexible facility, capable of accommodating various equilibrium configurations. The first divertor designed jointly with Eurofusion consortium is compatible with three reference magnetic configurations: SN-PT, XD and SN-NT. All PFUs (IVT, OVT and DOME) are tungsten armoured and actively cooled and then it will be caplable to withstand 20 MW/m2 in steady state.
In 2024 the first version of the Research Plan has been released. The plan has been prepared with the participation of a large number of researchers from all the Eurofusion laboratories. It will be used to focus the priorities of the facility on the most urgent ITER research needs to facilitate the start of ITER operation.
The design of the machine has been almost completed and several procurements for the realization of the DTT components are ongoing or have been launched. In this talk an overview of the project status, aimed at highlighting the status of procurement activities and the outlook for the completion of the facility and its exploitation, is reported.
The DTT construction is made under the responsibility of a Consortium (DTT scarl) that brings together all the public research institutions working in Italy in fusion research and the main Italian energy company, one of the best examples of public private partnership in fusion.
