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.

More about collaboration on

Environmental, Safety and Economic Aspects of Fusion Power (ESEFP)

The ESEFP TCP provides a platform for scientists and engineers to exchange information and further enhance the collaboration, coordinating international efforts to bridge the scientific and technical gaps between 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), and supporting governmental policies and raising awareness of fusion energy developments and potential to the general public.

Main areas of work

  • In-vessel tritium source terms (Task 1)
  • Activation products source terms (Task 3)
  • Failure rate database (Task 5)
  • Radioactive waste study (Task 6)
  • Socio-economic aspects of fusion power (Task 7)
  • Magnet safety (Task 8)

Key activities and accomplishments (2017-18)

  • Inventory and removal methods of hydrogen isotopes (Task 1)
  • Development of the MELCOR fusion codes (Task 3)
  • Data collection and analysis aimed toward failure rates and repair times (Task 5)
  • Study of water leaks on the Fusion Neutron Source (Task 6)
  • European survey to assess public attitude towards fusion; focus on public acceptance (Task 7)
  • Design study for a post-large helical device (REBCO) (Task 8)

Priorities and projects (2019-20)

  • Dynamic tritium transport simulation development (Task 1)
  • Ongoing assessment of safety impact of liquid metal plasma facing components (Task 3)
  • Data collection and analysis aimed toward failure rates and repair times of individual components for support for RAMI (reliability, availability, maintainability and inspectability)(Task 5)
  • Energy scenario evolutions explored by EUROfusion TIMES model (Task 7)

Multilateral collaborations

It would be valuable to further co-ordinate internationally socio-economic studies relating to fusion power.Chairs of the ESEFP TCP and TCP on Nuclear Technology of Fusion Reactors (NTFR TCP) attend each other's meetings with a view to finding work areas of mutual interest.


Why should your organisation become a member of ESEFP?

Participants in the ESEFP TCP exchange expertise with a view to better understanding the environmental, safety and economic issues associated with fusion power. Broad stakeholder engagement, managing public opinion, and a positive media framing of fusion devices is key in dealing with the overall socio-economic impact of this technology. The work of the ESEFP TCP serves to bring fusion science closer to the public and thus contribute to greater social consensus.
