Executive summary

The Indian fusion ecosystem — IPR (Institute for Plasma Research), ITER-India, the broader DAE network of laboratories that work on plasma physics and nuclear physics, the modest but growing private layer, and the academic departments that train the field’s next generation — is not the ecosystem it was in 2005. It has produced trained scientists, hosted international collaborations, and now has its first private-sector entrants under the SHANTI Act 2025 framework. Awareness is no longer the binding constraint; coordination is.

This piece proposes that India formalise an annual India Fusion Day — a recurring national-scale convening modelled on the Dutch precedent — as the smallest institutional step that matches the sector’s current maturity. The argument is not about commercial outcomes. It is about whether the country wants a single venue where the academic, government, regulator, and industry strands of fusion can be in one room.

1. What the Indian fusion ecosystem actually contains today

The strands, briefly:

  • IPR Gandhinagar — the Institute for Plasma Research, the country’s anchor plasma-physics laboratory, host of the ADITYA-U and SST-1 tokamaks, and the named host institution for several MSV2035-recommended programmes including the spherical-tokamak volumetric-neutron-source concept.
  • ITER-India — the domestic agency responsible for India’s contributions to ITER, located adjacent to IPR. The procurement, engineering, and personnel pipeline through ITER-India is among the most significant fusion-engineering training programmes in the country.
  • BARC and the broader DAE network — nuclear-physics, materials, and engineering capability across BARC, VECC, IGCAR, RRCAT, IUAC, SINP, TIFR. Each has fusion-adjacent work; none is purely fusion-focused.
  • Academic departments — plasma-physics and nuclear-engineering programmes at the IITs, IISc, and university-affiliated centres train the people who staff all of the above.
  • Private entrants — small in number, recent in time, operating under the SHANTI Act 2025 framework that came into force in December 2025. Includes ourselves.
  • International collaborations — ITER, EUROfusion, ELI-NP, Indo-Russian (BINP), Indo-Japan (J-PARC), DOE programmes. These are bilateral and multilateral, not centralised.

It is not a small ecosystem. It is a fragmented one. Each strand has its own funding cycle, its own publication channels, its own conference circuit, and its own institutional language. They rarely all sit in the same room.

2. The Dutch precedent

The Netherlands runs an annual Dutch Fusion Day: a one-day national convening hosted by the Dutch fusion community, where academic laboratories, DIFFER (the national plasma-physics institute), industrial partners, and international collaborators come together for a single shared programme. The agenda is not exotic — talks, panel discussions, poster sessions, a vendor exhibition — but the institutional effect is significant. It is the venue where the sector negotiates with itself, where new programmes are first floated, and where the country’s position on international fusion programmes is informally coordinated.

Several other fusion countries have analogous events: the UK’s Fusion Cluster days, Japan’s fusion-energy fora, the US fusion-association annual meetings. The institutional pattern is the same: a recurring national-scale venue that converts diffuse activity into visible community.

3. Why India is ready for this now

Two changes since 2020 make a recurring national convening newly viable:

The SHANTI Act 2025 framework. Until December 2025, private participation in nuclear-adjacent work was, in practice, not legally available for facility operations. That gate is now open. The participants in a hypothetical India Fusion Day now include both government laboratories and private operators — the same room contains different incentive structures, different time horizons, different reporting requirements. The agenda of such a convening is correspondingly richer.

The MSV2035 framing. The Government of India’s Mega Science Vision 2035 — Nuclear Physics already provides a shared technical agenda that fusion-adjacent work in India can be measured against. §2.7.1 (spherical-tokamak volumetric neutron sources), §4.1.3 (accelerator-driven sub-critical systems), §4.2.4 (plasma-technology commercialisation), and §5.2(b) (industry participation in mega-science projects) all give such a convening explicit ground to walk on.

The fusion sector in India does not need to invent its agenda. The Government already wrote one. What it needs is a venue to discuss progress against that agenda annually.

4. What an India Fusion Day would actually look like

The minimum-viable shape:

  • A one-day programme, hosted on rotation by IPR, BARC, an IIT, or another credible institutional venue
  • Plenary talks from the major laboratories — IPR, ITER-India, BARC, VECC — on their year’s work
  • An industry / private-sector track — including, but not limited to, accelerator vendors, magnet suppliers, vacuum-systems firms, and any private operators
  • A regulatory track — AERB, CDSCO (for medical applications), DST — on framework evolution
  • A student / early-career track — poster sessions, recruitment, fellowship announcements
  • A closing session on MSV2035 implementation status, with explicit gap-identification

This is not exotic. It is conference-organising. The cost is modest, the institutional barrier is low, and the convening can start with whatever participation it can muster in year one and grow over time. The Dutch event began small.

5. What an India Fusion Day would not be

It would not be a press-release factory. The point of a national-scale convening is not to announce things; it is to coordinate things. A useful test for the agenda is whether it produces conversations that are uncomfortable in their honesty — about timelines, about regulatory frustration, about gaps in the workforce, about which programmes are not delivering. An event that produces only good news is a marketing exercise, not an institution.

It would not be commercially partisan. The Dutch precedent is hosted by the academic community, with industry and government as participants. The Indian equivalent should follow that model. Private operators — including us — should attend, contribute, and be visible; the convening itself should not be branded with any single firm’s logo.

It would not be a substitute for the existing institutional structures. IPR’s Plasma Science Society of India conferences, BARC’s technical symposia, the academic-society meetings — all of these continue. India Fusion Day would sit alongside them as the one venue where everyone is in the same room.

6. The honest framing

An annual convening will not deliver fusion energy. It will not unblock licensing, fund research, or train scientists. What it will do is make the sector visible to itself — the most under-rated function of any institutional infrastructure. A country that wants to be taken seriously in a long-horizon technology has to be able to convene around that technology without the convening being a press event.

Our role, as a small private operator, is not to host this convening. It is to attend it when it happens, contribute where useful, and write pieces like this one to suggest that the sector is ready for the institutional step.
