Why in News: The Maharashtra government signed Memoranda of Understanding (MoUs) worth approximately ₹6.5 lakh crore in May 2026 for nuclear energy projects totalling 25,400 MW of installed capacity. The agreements — covering multiple sites in the state including the long-delayed Jaitapur Nuclear Power Project — are the largest nuclear investment commitments by any Indian state and form a key pillar of India’s national target of 100 GW of nuclear power by 2047 under Vision 2047.
Background: India’s Nuclear Energy Targets
India’s civilian nuclear programme has historically been modest relative to the country’s energy ambitions. As of early 2026, the country’s total installed nuclear capacity stands at approximately 7,480 MW from 22 operational reactors across seven sites, all operated by the Nuclear Power Corporation of India Limited (NPCIL).
The government has set an ambitious roadmap:
| Target | Capacity | Timeline |
|---|---|---|
| Current operational capacity | ~7,480 MW | As of May 2026 |
| Under construction / committed | ~6,700 MW | 2026–2031 |
| Vision 2047 nuclear target | 100 GW | By 2047 |
| Share of electricity mix (2047 goal) | ~25% | By 2047 |
Achieving 100 GW from the current ~7.5 GW base requires roughly a 13-fold expansion in 21 years — an unprecedented pace that demands both domestic manufacturing scale-up and large foreign investment partnerships.
The Maharashtra MoUs: Key Details
The Maharashtra MoUs aggregate multiple investment agreements signed at the Magnetic Maharashtra 2.0 / Global Investors Summit framework and bilateral government-to-government negotiations. The total portfolio covers 25,400 MW across new-build nuclear sites in the state.
MoU Summary Table
| Project / Partner | Technology | Capacity | Estimated Investment |
|---|---|---|---|
| Jaitapur Nuclear Power Project (NPCIL + EDF/Framatome) | EPR (Evolutionary Power Reactor) | 9,900 MW (6 × 1,650 MW) | ~₹1.5–2 lakh crore (est.) |
| Additional NPCIL fleet expansion (Maharashtra sites) | PHWR / future technologies | ~8,000 MW | ~₹1.8 lakh crore (est.) |
| ASHVINI (NPCIL 51%–NTPC 49% JV) | PHWR / SMR pathway | ~4,000 MW | ~₹1 lakh crore (est.) |
| Adani / private PSU JV pipeline (subject to Atomic Energy Act amendment) | To be determined | ~3,500 MW | ~₹1 lakh crore (est.) |
| Total (all MoUs) | Mixed | 25,400 MW | ~₹6.5 lakh crore |
Note: Individual MoU investment figures are government estimates; actual costs depend on finalised reactor models, financing terms, and construction timelines. EPR cost overruns in Europe (Flamanville, Hinkley Point C) make precise estimates inherently uncertain.
Jaitapur Nuclear Power Project — Deep Dive
The Jaitapur Nuclear Power Project (JNPP) is the centrepiece of Maharashtra’s nuclear ambitions and, if completed, will be the largest nuclear power plant in the world by installed capacity.

Jaitapur: Challenges and Controversies
1. Land Acquisition and Local Opposition Local fishing and farming communities in Madban and surrounding villages have opposed the project since 2010, citing threats to coastal livelihoods, the Konkan mango belt (Alphonso GI tag), and seismic risks. The Konkan coast lies near seismically active zones.
2. Cost and Financing EPR projects in Europe have suffered severe cost overruns — Flamanville 3’s cost rose from €3.3 billion (2006 estimate) to over €13 billion (2024 revised). India seeks a competitive per-unit cost through economies of scale (6 reactors at one site) and indigenisation.
3. Civil Liability for Nuclear Damage Act, 2010 (CLND) The CLND Act’s Section 17(b) allows NPCIL to pursue the equipment supplier for damages in the event of a nuclear accident caused by supplier defect. This supplier liability clause has been a major sticking point for EDF/Framatome, as it diverges from the Convention on Supplementary Compensation for Nuclear Damage (CSC) framework, which channels all liability to the operator. India ratified the CSC in 2016, but the domestic CLND Act’s wording remains unchanged — creating legal ambiguity that foreign suppliers view as a commercial risk.
4. Strategic Significance Jaitapur is a cornerstone of the Indo-French strategic partnership. It was a deliverable of the 2008 civil nuclear deal with France and has been referenced in every India–France summit since. The 2023 Bastille Day visit of PM Modi to France and the 2024 Republic Day visit of President Macron both included Jaitapur progress as an agenda item.
Nuclear Legal Framework — SHANTI Act, 2025 (Replaced AEA 1962)
[UPDATE: The Atomic Energy Act, 1962 was repealed by the SHANTI Act, 2025, which received Presidential assent in December 2025.]
The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act, 2025 replaced both the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010, fundamentally restructuring India’s nuclear legal framework.
Key Changes Under SHANTI Act, 2025
| Provision | Effect |
|---|---|
| Private sector participation | Private Indian companies and JVs can now build, own, operate, and decommission nuclear power plants under a government licence — the six-decade-old state monopoly is ended |
| Foreign investment | FDI up to 49% permitted in specified nuclear activities under the automatic route |
| Retained government control | Enrichment of nuclear material, production of heavy water, and management of spent fuel beyond on-site storage remain with the Central Government |
| AERB status | Atomic Energy Regulatory Board (AERB) given formal statutory independence as the sector regulator |
| Supplier liability | Supplier liability provisions of the erstwhile CLND Act removed; operator liability capped based on plant capacity — aligning with international conventions (CSC) |
| Weapons material | Controlled by Department of Atomic Energy (DAE) — unchanged |
PSU Joint Ventures (Pre-SHANTI)
Under the 2022–2023 amendments to the Atomic Energy Rules, the first PSU–PSU joint venture was permitted:
- ASHVINI (Anushakti Vidhyut Nigam Ltd.) — a JV between NPCIL (51%) and NTPC Ltd (49%), approved by the Government on September 11, 2024. ASHVINI can build and operate nuclear plants with NPCIL as the technology and safety backstop. Under SHANTI, private companies can now also form JVs or independently develop nuclear plants.
The MoUs signed by Maharashtra at the Magnetic Maharashtra 2.0 summit, which include potential private sector investment pipelines, are now legally viable under the SHANTI Act framework.
Civil Liability for Nuclear Damage Act, 2010 (CLND) — Now Repealed by SHANTI Act
[NOTE: The CLND Act, 2010 was repealed by the SHANTI Act, 2025 (December 2025). The SHANTI Act removes supplier liability and caps operator liability by plant capacity, aligning India with international conventions. The provisions below are historical context explaining why the CLND Act was a barrier to Jaitapur and other projects for over a decade.]
The Civil Liability for Nuclear Damage Act, 2010 had established the liability regime for nuclear accidents in India, implementing India’s ratification of the Convention on Supplementary Compensation for Nuclear Damage (CSC).
Key Provisions
| Section | Provision |
|---|---|
| Section 6 | Operator (NPCIL) is strictly liable for nuclear damage — no proof of negligence required |
| Section 7 | Operator’s liability capped at ₹1,500 crore per incident |
| Section 8 | Central Government covers damages beyond operator cap (unlimited liability in practice) |
| Section 17(a) | Operator right of recourse against supplier if accident caused by wilful act or gross negligence |
| Section 17(b) | Operator right of recourse against supplier if nuclear contract includes such a clause (controversial) |
| Section 46 | Preserves rights under other laws — broader civil and criminal liability pathway |
The Section 17(b) Controversy
Section 17(b) is unique globally — it allows NPCIL to seek indemnity from the equipment supplier not just for wilful fault but through contractual inclusion of supplier liability clauses. Western reactor vendors (EDF, Westinghouse, GE-Hitachi) argue this creates open-ended financial risk for suppliers, making nuclear project insurance and financing difficult. The International Atomic Energy Agency (IAEA) has noted India’s CLND framework diverges from international norms.
Various workarounds have been proposed — nuclear insurance pools, government-backed indemnity funds, and side letters — but no final resolution has been reached, partly explaining the decades-long delay at Jaitapur.

| Total (operational) | — | — | ~22 | ~7,480 MW |
India’s Three-Stage Nuclear Programme
India’s nuclear strategy follows the Three-Stage Programme conceived by Dr. Homi J. Bhabha to achieve thorium fuel self-sufficiency — India holds approximately 25% of global thorium reserves.
| Stage | Reactor Type | Fuel | Goal |
|---|---|---|---|
| Stage 1 | PHWR (Pressurised Heavy Water Reactor) | Natural uranium | Produce plutonium |
| Stage 2 | FBR (Fast Breeder Reactor) | Plutonium + thorium | Breed U-233 from thorium |
| Stage 3 | Advanced Heavy Water Reactor (AHWR) | U-233 / thorium | Full thorium cycle |
The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, operated by BHAVINI (Bharatiya Nabhikiya Vidyut Nigam Limited), marked India’s transition from Stage 1 to Stage 2. It achieved first criticality in September 2024 and is approaching full-power commissioning.
Nuclear Energy: Environment and Climate Dimension
Nuclear power is a low-carbon, baseload energy source — critical for India’s climate commitments:
- India’s Nationally Determined Contribution (NDC) under the Paris Agreement targets 50% non-fossil electricity capacity by 2030 and net-zero by 2070.
- Nuclear’s lifecycle carbon emissions (~12 gCO₂/kWh) are comparable to wind energy and far below coal (~820 gCO₂/kWh).
- Unlike solar/wind, nuclear provides firm, dispatchable power — not dependent on weather.
- The 25,400 MW proposed for Maharashtra alone would, if realised, displace approximately 130–150 million tonnes of CO₂ per year (vs. coal at same capacity factor).
