A significant part of the work programme of EUROfusion is devoted to the activities related to DTT. EUROfusion, the European Consortium for the Development of Fusion Energy, manages European fusion research activities on behalf of EURATOM.


Two Work Packages of the 2014-218 EUROfusion work plan are focused on DTT, entirely in support of Headline 2.4 (Investigate alternative power exhaust solutions for DEMO) with a planned investment of more than 60 MEUR from EUROfusion Consortium and EUROfusion members:


  • WPDTT1: Assessment of alternative divertor geometries and liquid metals PFCs

The general objective of WPDTT1 is the assessment of:

  • requirements for physics model development
  • DEMO compatibility of alternative divertor designs including SX and SF divertors
  • DEMO compatibility of liquid metal PFCs with selection of best liquid metal, if viable


  • WPDTT2: Definition and Design of the Divertor Tokamak Test Facility

The general objective of WPDTT2 is to design an experiment addressed to the solution of the power exhaust issues in view of DEMO. This derives from the need to develop integrated, controllable exhaust solutions for DEMO including plasma, PFCs, control diagnostics and actuators, using experiments, theory and modelling [ https://www.create.unina.it/dtt2 ]


In addition, there is an opportunity presented by the Italian government for acquiring additional funding for a dedicated exhaust facility. The proposal is among the projects submitted to the 315 billion Euro of Juncker's plan (EFSI: European Fund for Strategic Investments) with a budget of 500 million Euro:


The "Construction of a Divertor Tokamak Test Facility for fusion energy research" DTT proposal is the 5th one of the Italian list under "A. Knowledge, SMEs and the digital economy” presented by ENEA and Italian Ministry of Economic Development. The DTT facility will foster the development of fusion energy being devoted to provide the solution for one of the main issue impacting on the operation of fusion reactor, i.e. the efficient power handling. The DTT facility design is currently under finalization at European level.


In March 2015 the EUROfusion General Assembly welcomed the opportunity of gaining additional resources for the DTT, suggesting that the activities of concept, objectives and design are carried out in a truly European framework with WPDTT1 and WPDTT2.
