The bigger ambition is SST-Bharat, a proposed reactor designed to move India from experimental fusion toward producing net fusion energy. - Author: TGV Desk - Tags: India, that is Bharat, Tech, has-audio India has taken another step in its effort to recreate on Earth the same nuclear reaction that powers the Sun. At the Institute for Plasma Research in Gandhinagar, scientists have installed and integrated a new 82.6 GHz, 400-kilowatt gyrotron with the SST-1 tokamak, one of India’s principal experimental fusion machines. The device fires high-power microwaves into plasma, allowing researchers to heat it more effectively and study how ultra-hot plasma can be sustained and controlled for longer periods. That is where the popular description “artificial sun” comes from. A tokamak does not create a miniature star. Instead, it tries to reproduce the underlying process that makes stars shine: nuclear fusion. Light atomic nuclei are heated until matter becomes plasma and, under the right conditions, fuse together, releasing enormous amounts of energy. The challenge is brutal. Plasma has to be heated to temperatures far above those found at the Sun’s surface and then confined without touching the reactor walls. Tokamaks use powerful magnetic fields to hold that plasma inside a doughnut-shaped chamber. India has been working on this problem for decades. Its fusion programme began with ADITYA, followed by ADITYA-U and SST-1\. The Department of Atomic Energy says these programmes have helped India develop superconducting magnets, cryogenic systems, high-power heating technologies, neutral beams and other capabilities needed for future fusion reactors. But SST-1 itself is not a commercial power plant, and it is not currently producing electricity from fusion. The larger ambition lies ahead. Scientists at IPR have proposed SST-Bharat, a much more advanced steady-state deuterium-tritium fusion machine intended to bridge the gap between experimental plasma physics and actual power production. According to a roadmap published in *Current Science*, SST-Bharat would aim to demonstrate net fusion power in conditions closer to those required inside a future power station. IPR Director Dinesh Aswal has said SST-Bharat could target roughly 170 MW of fusion power and may cost between ₹20,000 crore and ₹25,000 crore, with construction potentially taking around a decade if the project receives approval. The longer-term roadmap envisages an indigenous demonstration reactor capable of producing electricity. India is also a major partner in ITER, the enormous international fusion experiment being built in France. Indian industry has supplied critical components including ITER’s giant cryostat, cooling-water systems, cryogenic equipment and neutron-shielding structures. Fusion remains one of energy science’s most difficult promises. Unlike conventional nuclear fission, it aims to fuse rather than split atoms, and researchers hope future reactors could provide immense quantities of low-carbon energy with far less long-lived radioactive waste. But commercial fusion is still years, possibly decades, away. India’s Department of Atomic Energy itself says major breakthroughs are still required before fusion can become commercially usable.
