Introduction

The International Atomic Energy Agency (IAEA) fosters the exchange of scientiﬁc and technical

results in nuclear fusion research and development through its series of Fusion Energy Conferences.

The 29th Fusion Energy Conference (FEC 2023) aims to provide a forum for the discussion of key

physics and technology issues as well as innovative concepts of direct relevance to the use of nuclear

fusion as a future source of energy.

According to the IAEA’s Fusion Device Information System (FusDIS), as of 2023, there are al-

most 130 experimental fusion devices and testing facilities operating, under construction or being

planned, and a dozen of demonstration plant or pilot plant designs under development. Driven by

recent scientiﬁc and technical advances, a vibrant private sector and the climate crisis, attention is

switching to the remaining challenges of demonstrating the technological feasibility of fusion power

as well as the safe and economic viability of this energy source.

The scope of FEC 2023 is, therefore, intended to reﬂect the priorities of this new era in fusion energy

research, technology development and preparation to industrial deployment. The conference aims

to serve as a platform for sharing the results of research and development eﬀorts in both national

and international fusion programmes that have been shaped by these new priorities, and to thereby

help in pinpointing worldwide advances in fusion theory, experiments, technology, engineering,

materials, advanced concepts, safety, socio-economics and preparation to industrial deployment.

Furthermore, the conference will also set these results against the backdrop of the requirements

for a net energy-producing fusion device and a fusion power plant in general and will thus help in

deﬁning the way forward.

With the participation of international organizations such as the ITER International Fusion Energy

Organization and the European Atomic Energy Community (Euratom), as well as the collaboration

of more than 40 countries and a great number of research institutes and organisations, including

those working on smaller devices, it is expected that this conference will, like previous conferences

in the series, serve to identify the possibilities and means for continuous and eﬀective international

collaboration in this area.

The 29th IAEA Fusion Energy Conference is being organized by the IAEA in cooperation with

the Government of the United Kingdom through the United Kingdom Atomic Energy Author-

ity (UKAEA). Previous conferences in this series were held in Salzburg, Austria (1961), Cul-

ham, United Kingdom (1965), Novosibirsk, Russian Federation (1968), Madison, United States

of America (1971), Tokyo, Japan (1974), Berchtesgaden, Germany(1976), Innsbruck, Austria

(1978), Brussels, Belgium (1980), Baltimore, United States of America (1982), London, United

Kingdom (1984), Kyoto, Japan (1986), Nice, France (1988), Washington DC, United States of

America (1990), Würzburg, Germany (1992), Seville, Spain (1994), Montreal, Canada (1996),

Yokohama, Japan (1998), Sorrento, Italy (2000), Lyon, France (2002), Vilamoura, Spain (2004),

Chengdu, China (2006), Geneva, Switzerland (2008), Daejeon, Republic of Korea (2010), San

Diego, United States of America (2012), St. Petersburg, Russian Federation (2014), Kyoto, Japan

(2016), Ahmedabad, India (2018), Nice, France (postponed from 2020 to 2021 and held online

because of the global COVID-19 pandemic).

Conference Material

Contributed papers will be published electronically on the IAEA Fusion Portal under the FEC ded-

icated webpage as a part of the FEC material.

Nuclear Fusion Journal

Participants have been invited to submit their paper for possible publication in the IAEA journal,

Nuclear Fusion. If your institution does not have access to the journal, pdfs of these FEC derived

articles can be requested from [email protected]g.

Links on the abstract pages direct the reader to both the pre-print and the Nuclear Fusion journal,

respectively.

Participation in an IAEA Scientiﬁc Meeting

Governments of Member States and those organizations whose activities are relevant to the meeting

subject matter are invited to designate participants in the IAEA scientiﬁc conferences and symposia.

In addition, the IAEA itself may invite a limited number of scientists as invited speakers. Only

participants designated or invited in this way are entitled to present papers and take part in the

discussions.

Representatives of the press, radio, television or other information media and members of the pub-

lic, the latter as “observers”, may also be authorized to attend, but without the right to take part in

the proceedings.

Scientists interested in participating in any of the IAEA meetings should request information from

the Government authorities of their own countries, in most cases the Ministry of Foreign Aﬀairs or

national atomic energy authority.
