Nuclear Dreams, Delayed Reality
India's Nuclear Energy Mission promises an ambitious future: 100 GW of nuclear power capacity by 2047, backed by the SHANTI Act, greater private participation, Small Modular Reactors (SMRs), and Fast Breeder Reactors (FBRs). Yet beneath this grand vision lies a stark contradiction. Not a single new nuclear power project has been sanctioned in the last three years. In energy policy, credibility is measured not by megawatts announced but by reactors commissioned. Unless execution catches up with ambition, the Nuclear Energy Mission risks becoming another impressive roadmap with little movement on the ground.
There is little doubt that nuclear energy must play a vital role in India's clean energy transition. Unlike solar and wind, it provides reliable baseload electricity, emits minimal greenhouse gases during operation, and strengthens energy security by reducing dependence on imported fossil fuels. As electricity demand is expected to more than double by 2047, driven by manufacturing, electric mobility, artificial intelligence, and data centres, achieving Net Zero by 2070 will require a diversified energy mix in which nuclear power complements renewables rather than competes with them.
The challenge, however, lies not in vision but in delivery. India's installed nuclear capacity stands at about 9 GW. Reaching 100 GW within two decades demands an eleven-fold expansion, an unprecedented feat requiring sustained political commitment, institutional capacity, financing, domestic manufacturing, and regulatory efficiency. The government has announced the destination, but the roadmap remains far less convincing. Annual capacity targets, financing plans, supply-chain preparedness, and project timelines remain largely unclear.
India's nuclear programme has historically been constrained less by technology than by governance. Projects routinely face delays due to land acquisition disputes, environmental clearances, local opposition, bureaucratic approvals, financing constraints, and procurement bottlenecks. The Kudankulam Nuclear Power Project experienced years of delay because of technical and social challenges, while the Jaitapur project has remained stalled for over a decade amid negotiations and local resistance. Every year of delay inflates construction costs, raises financing burdens, and postpones the delivery of much-needed clean electricity. More importantly, every delayed reactor represents scarce public capital locked away instead of strengthening transmission networks, battery storage, or renewable integration.
The SHANTI Act marks an important shift by opening the sector to wider public and private participation. Yet legislation alone cannot transform the industry. Nuclear power plants demand enormous upfront investments with long gestation periods before generating returns. Private investors will seek more than policy intent; they require predictable regulation, viable risk-sharing mechanisms, and clarity on accident liability. The unresolved concerns surrounding India's nuclear liability framework have long discouraged foreign suppliers and investors. Unless these structural issues are addressed, private participation may remain more aspirational than transformative.
Technology, too, requires realism alongside optimism. Indigenous Pressurised Heavy Water Reactors (PHWRs) have become the backbone of India's programme and deserve continued expansion. However, SMRs are still commercially evolving worldwide, while Fast Breeder Reactors, despite their importance in India's three-stage nuclear programme and thorium ambitions, have faced decades of technological complexity and delays globally. Research and development are essential, but technological optimism should not substitute for realistic deployment strategies.
Fuel security presents another challenge. Despite expanding domestic mining, India continues to depend significantly on imported uranium. A large-scale nuclear expansion will require diversified international fuel partnerships, strategic reserves, accelerated domestic exploration, and sustained investment in thorium research. Equally important is the development of indigenous manufacturing capabilities for reactor components, specialised materials, and skilled manpower, without which ambitious capacity targets will remain difficult to achieve.
Expansion must also be accompanied by stronger regulation and public trust. Nuclear accidents from Chernobyl to Fukushima demonstrated that safety failures can erase decades of public confidence. India should strengthen the independence of its nuclear regulatory architecture, improve nuclear waste management, enhance emergency preparedness, and engage local communities transparently rather than treating consultation as a procedural formality. Communities living near proposed reactor sites must become stakeholders in development, not obstacles to be managed.
International experience offers valuable lessons. France illustrates both the advantages of dependable low-carbon nuclear power and the costs of maintaining ageing reactors. China's rapid expansion reflects exceptional state capacity, manufacturing strength, and timely execution rather than ambitious announcements alone. Meanwhile, even the United States continues to struggle with cost overruns and project delays despite advanced technology. The common lesson is unmistakable: institutions matter more than intentions.
India undoubtedly needs more nuclear power to secure its energy future. But reactors cannot be commissioned through speeches, legislation, or aspirational targets alone. They require efficient institutions, predictable regulation, robust financing, technological realism, and unwavering accountability. The Nuclear Energy Mission is a necessary vision for Viksit Bharat, but unless the government bridges the persistent gap between policy announcements and project execution, the promise of 100 GW by 2047 risks illuminating political speeches far more than India's power grid.
