FusDIS

The Fusion Facility Database (FFDB), developed and maintained by the IAEA, provides comprehensive information on fusion facilities worldwide. It covers public and private facilities with experimental or plant designs (including demonstration, prototype, and power plants) that are operational, under construction, or planned. FFDB also includes detailed technical data, country-level statistics, and research statistics derived from the Fusion Energy Conference series. All information is collected by the IAEA and undergoes review with the involvement of the International Fusion Research Council.

Complementing the database, the World Survey of Fusion Devices 2022 offers an in-depth global overview of fusion research and development activities, while the IAEA’s World Fusion Outlook regularly features statistics and analysis drawn from FFDB. Together, these resources highlight FFDB’s role as an authoritative and widely cited reference for the global fusion community.

About FFDB

The fusion facilities are organized in

2 main designs:

Experimental - designed primarily for research and development, focusing on plasma physics, confinement methods, and technology testing. These facilities do not produce electricity or usable heat.
Plant - including demonstration units, prototypes, and eventual commercial power plants. These are designed to integrate full fuel cycles and energy conversion systems, with the goal of generating electricity and/or usable heat.

4 main configuration categories:

Tokamaks - both conventional and spherical type
Stellarators and Heliotrons
Laser/Inertial
Alternative Concepts - this category includes the following types: dense plasma focus; field reversed configuration; inertial electrostatic fusion; levitated dipole; magnetic mirror machine; magnetized target fusion; pinch; reverse field pinch; simple magnetized torus; space propulsor; spheromak.

For each facility, the info below can be visualized by hovering the cursor over the marker:

Country
Organization
Name
Configuration
Type
Status (operating; under construction; planned)
Design (exp - exerimental; plant)
Ownership (public; private)
Website (each website can be launched by clicking on the device marker).

The statistics provided can be used as filters. It is also possible to filter per country by choosing each country from the tables.

In addition, the following dashboards are available:

Tech Data: 0D design parameters of tokamaks and stellarators/heliotrons in operation, under construction or planned, with experimental and plant designs.
Country Stats: Number of fusion facilities per country, per design, status and configuration.
Org Stats: Number of fusion facilities per organization, per design, status and configuration.
FEC2025 IDX: Number of first authorship papers accepted at FEC2025 per country and per track. Categories are: EX - Magnetic Fusion Experiments; TH - Magnetic Fusion Theory and Modelling; TECH - Fusion Energy Technology; IFE - Inertial Fusion Energy; IAC - Innovative and Alternative Fusion Concepts; PWF - Pathways to Fusion; OV - Overview.
FECs IDX: Number of first authorship papers accepted at FEC2006–2025 per country and per track; and total number of papers per FEC and per track. Categories are: EX - Magnetic Fusion Experiments; TH - Magnetic Fusion Theory and Modelling; TECH - Fusion Energy Technology; IFE - Inertial Fusion Energy; IAC - Innovative and Alternative Fusion Concepts; PWF - Pathways to Fusion; OV - Overview.
Country Profiles: Detailed information on each country (by using the filter).
