Technology Collaboration Programme

Advancing the research, development and commercialisation of energy technologies

The IEA Technology Collaboration Programme supports the work of 38 independent, international groups of experts that enable governments and industries from around the world to lead programmes and projects on a wide range of energy technologies and related issues.

Tokamak Programmes (CTP)

The CTP TCP supports the development of fusion energy by contributing to the physics basis of the International Thermonuclear Experimental Reactor (ITER), and DEMO (a proposed nuclear fusion power station that is intended to build upon the ITER experimental nuclear fusion reactor) design optimisation. The CTP TCP provides a forum for tokamak programmes of the ITER Members to co-ordinate tokamak research by carrying out scientific and technological exchanges, holding workshops and meetings for the purpose of advancing the tokamak concept in the context of fusion energy, and supporting ITER physics and technology needs.

Main areas of work

  • Experimental programme plans for the tokamak facilities
  • Design and planning of experiments to contribute to the database for the next-generation tokamak devices including, but not limited to, support of activities identified by the International Tokamak Physics Activity (ITPA)
  • Experimental, theoretical and technical studies

Key activities and accomplishments (2017-18)

  • Co-ordinated multi-experiments and simulations aimed at improving the physics basis of plasma facing components power loading and melt dynamics
  • Improved understanding of the dynamics and control of ITER plasma terminations

Priorities and projects (2019-20)

  • Addressing the avoidance, control and mitigation of the key plasma instabilities
  • Protection of the plasma facing components and access to good confinement plasma regimes in ITER
  • Specific test for one of the systems to be installed in ITER to mitigate the consequences of the abrupt termination of the plasma "Disruptions" to be installed on JET (Joint European Torus)

Multilateral collaborations

Framework agreement between four CTP TCP partners to design, construct, install and operate ITER relevant hardware on JET. Mitigation of disruptions is a critical issue for ITER; it is important to test the concept of Shattered Pellet Injection (SPI) for mitigation of runaway electrons during the disruption current quench. The commissioning with plasma of the JET SPI and experimental campaign will take place in 2019.


  • International Thermonuclear Experimental Reactor (ITER) Organization

Why should your organisation become a member of CTP?

The CTP TCP is one of the main programmes for the implementation of the ITPA, which now operates under the auspices of the ITER Organisation and co-ordinates activities among the domestic programmes of the signatories to the ITER Agreement. The next critical step in demonstrating the scientific feasibility of fusion energy is to demonstrate burning plasmas in long pulses. As achieving this objective is a great challenge, and there are many scientific and technological issues to be addressed, this is the primary mission of ITER and of tokamak research programmes worldwide.
