Finance Minister Nirmala Sitharaman visited the ITER facility in France, praising the significant technical contributions of Indian scientists and firms like L&T and TCS to the world's largest nuclear fusion project. Her visit emphasized India’s role in developing critical reactor components and its strategic partnership in global clean energy research.
CADARACHE, France — Union Finance Minister Nirmala Sitharaman visited the International Thermonuclear Experimental Reactor (ITER) facility in Cadarache, France, on Saturday, July 4, 2026. The visit served to highlight India’s significant technical and industrial involvement in the international nuclear fusion research project, which aims to demonstrate the feasibility of fusion as a safe and virtually limitless source of clean energy.
Sitharaman toured the facility, including key operational areas such as the Cleaning Hall, Assembly Hall, and the Tokamak Pit. Throughout her visit, she was briefed by ITER officials on India’s role as one of the project's seven core member states.
A Milestone in Global Scientific Collaboration
The ITER project represents one of the world's largest scientific collaborations, involving the European Union, India, China, Japan, South Korea, Russia, and the United States. As a key partner, India is responsible for 9% of the project's "in-kind" contributions.
Sitharaman lauded the dedication of Indian scientists, engineers, and associates who have worked on the project for over two decades. "The Union Finance Minister appreciated the dedication of the ITER engineers and scientists engaged in the ITER experiment, which is one of the most ambitious nuclear fusion energy projects in the world, and a significant step toward sustainable and limitless clean energy for the future," the Ministry of Finance stated in an official release.
Indian Industry at the Forefront
A critical highlight of the visit was the recognition of Indian private and public sector companies that have provided essential technological support. The Finance Minister specifically commended the contributions of several notable industry players, including:
During her visit, Sitharaman held direct interactions with Indian professionals, including representatives from L&T and an engineer from Tamil Nadu, who are currently stationed at the Cadarache site. These companies have been instrumental in manufacturing complex components, including cooling water systems, cryogenic systems, and radio-frequency (RF) heating systems, meeting the stringent nuclear safety norms required for the reactor.
India’s Strategic Deliverables
India’s involvement, coordinated by the ITER-India project under the Institute for Plasma Research (IPR), Ahmedabad, encompasses the delivery of nine major "in-kind" packages. These include:
The Cryostat: The world’s largest high-vacuum pressure chamber, essential for insulating the tokamak.
Cooling Water and Heat Rejection Systems: Sophisticated systems to manage the intense heat generated during fusion experiments.
RF Heating Systems: Technology used to heat plasma to extreme temperatures, critical for achieving sustained fusion reactions.
Why It Matters
The visit underscores India’s growing stature in high-end global scientific research and its commitment to a sustainable energy transition. By contributing both financially and through industrial expertise, India is not only helping realize a future of clean, abundant energy but is also strengthening its domestic industrial ecosystem by mastering first-of-its-kind engineering technologies.
Key Facts at a Glance
