Transforming India’s nuclear power landscape

Have sufficient facts from PIB (Tier 1) plus Tier 4 sources. Writing the note.

1. At a Glance

• India is undertaking a structural overhaul of its nuclear power sector, opening it to private participation for the first time via the SHANTI Act, 2025, targeting 100 GW installed nuclear capacity by 2047, up from 8,180 MW as of early 2025 [S1][S2].
• Historically a state monopoly under the Department of Atomic Energy (DAE), nuclear power was governed by the Atomic Energy Act, 1962 — now repealed [S1][S2].
• Relevant for UPSC as it combines energy security, legislative reform, federal regulatory architecture, and climate/decarbonisation goals — a recurring GS-II/GS-III theme.
• Full realisation of the 100 GW target hinges on unresolved implementation issues: tariff design, fuel ownership, waste management, insurance, dispute settlement, and regulatory autonomy [S3].

2. Why in the News

• In the 2025-26 Union Budget speech, Finance Minister Nirmala Sitharaman announced the 100 GW-by-2047 nuclear target and signalled major legislative reform [S3].
• The SHANTI Bill, 2025 was introduced and passed rapidly: tabled in Lok Sabha on 15 December 2025, passed by Lok Sabha on 17 December, by Rajya Sabha on 18 December, and received Presidential assent from Droupadi Murmu on 20 December 2025 [S1][S2].
• The Act repeals and replaces the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act (CLNDA), 2010 [S1][S3].
• Commentary (April 2026) flags that implementation — rules, tariff frameworks, liability clarity — remains pending despite the Act's passage [S3].

3. Background & Evolution

• 1962: Atomic Energy Act enacted, vesting all nuclear activity exclusively with the DAE — no private or foreign entry [S1][S3].
• 2010: Civil Liability for Nuclear Damage Act (CLNDA) enacted post the India-US civil nuclear deal, to address supplier/operator liability; long criticised as a deterrent to foreign reactor suppliers [S1].
• 2025-26 Budget: 100 GW-by-2047 nuclear target announced; reform of nuclear legislation flagged [S3].
• December 2025: SHANTI Bill introduced, passed by both Houses, and enacted within days [S1][S2].
• SHANTI Act, 2025: consolidates and replaces the 1962 Act and CLNDA 2010; permits private companies to build/own/operate nuclear plants; grants statutory status to AERB [S1][S2][S3].

4. Core Static Facts

5. Multi-Dimensional Analysis

Economic - Enables private capital into a capital-intensive sector previously reliant solely on state (DAE/NPCIL) financing, potentially unlocking large-scale investment [S1][S2]. - Tariff-setting mechanism for privately generated nuclear power remains unresolved — a key implementation gap [S3].

Legal/Constitutional - Repeals two long-standing central Acts (1962, 2010) and replaces them with a single consolidated statute — a rare instance of full legislative replacement rather than amendment [S1][S3]. - Revises the nuclear liability framework (previously under CLNDA 2010, criticised for supplier liability clauses deterring foreign OEMs) to be more investment-friendly [S3].

Administrative/Governance - Grants AERB statutory status, addressing long-standing criticism that the regulator (AERB) and operator (DAE/NPCIL) sat within the same administrative structure, undermining regulatory independence [S2]. - Implementation now requires framing of subordinate rules/regulations on tariffs, fuel ownership, waste management, insurance, and dispute settlement [S3].

Scientific/Technological - Opens scope for private manufacturing of nuclear equipment and plant operation, potentially accelerating deployment of new reactor technology [S1].

Environmental - Nuclear expansion is positioned as a decarbonisation lever supporting India's clean energy and Viksit Bharat 2047 goals [S3].

Geopolitical/Strategic - FDI in atomic energy remains barred, limiting direct foreign ownership even as liability reform aims to attract foreign reactor suppliers/technology partners [S1][S2].

6. Recent Developments (last 12-18 months)

• 17 Dec 2025: Passed by Lok Sabha [S1][S2].
• 18 Dec 2025: Passed by Rajya Sabha [S1][S2].
• 20 Dec 2025: Presidential assent granted; SHANTI Act, 2025 enacted [S1][S2].
• April 2026: Analysts note implementation rules (tariffs, liability, waste management, dispute resolution) still pending [S3].

7. Prelims Hooks

• SHANTI = Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India [S1].
• SHANTI Act, 2025 repeals the Atomic Energy Act, 1962 and CLNDA, 2010 [S1][S3].
• India's nuclear capacity as of January 2025: 8,180 MW [S1].
• Target: 100 GW (1,00,000 MW) nuclear capacity by 2047 [S1][S3].
• 100 GW target first announced in the 2025-26 Union Budget speech by FM Nirmala Sitharaman [S3].
• SHANTI Bill passed Lok Sabha on 17 December 2025 and Rajya Sabha on 18 December 2025 [S1][S2].
• Presidential assent to SHANTI Act given on 20 December 2025 by President Droupadi Murmu [S1][S2].
• AERB (Atomic Energy Regulatory Board) has been granted statutory status under the SHANTI Act [S1][S2].
• Nodal department for nuclear power historically: Department of Atomic Energy (DAE), not Ministry of Power [S3].
• SHANTI Act permits private companies to build, own, and operate nuclear power plants — a first in Indian nuclear history [S1].
• FDI in atomic energy continues to be prohibited even after the SHANTI Act [S1][S2].
• Central Government licence + separate AERB safety authorisation are both required for nuclear facilities [S1].
• CLNDA, 2010 was enacted in the context of India's civil nuclear cooperation deals (e.g., India-US) [S1].

8. Mains Relevance

• GS-III: Infrastructure — Energy; Science & Technology — indigenization/nuclear technology; Government policies and interventions.
• GS-II: Statutory bodies (AERB); Government policies for various sectors.
• Possible question stems: 1. "Discuss the significance of the SHANTI Act, 2025 in transforming India's nuclear energy governance. What implementation challenges remain in realising the 100 GW target by 2047?" 2. "Examine how granting statutory status to the AERB addresses concerns of regulatory independence in India's nuclear sector." 3. "Private sector participation in nuclear power is a paradigm shift from India's traditional state-monopoly model. Critically evaluate the risks and opportunities."

9. Related Topics to Study Next

• Civil Liability for Nuclear Damage Act, 2010 — the liability regime just repealed; useful for before/after comparison.
• India-US Civil Nuclear Deal (123 Agreement) — context for why CLNDA 2010 was originally shaped the way it was.
• NPCIL (Nuclear Power Corporation of India Ltd) — the DAE PSU that has been the sole operator till now.
• Viksit Bharat @2047 — the overarching policy vision the nuclear target is nested in.
• National Green Hydrogen Mission / renewable energy targets — comparative clean-energy policy instruments.
• Small Modular Reactors (SMRs) — technology trend relevant to private-sector entry.
• Statutory regulatory bodies in India (SEBI, TRAI, AERB) — comparative governance/independence theme.
• India's Nationally Determined Contributions (NDCs) under UNFCCC — decarbonisation linkage.

10. Common Errors / Trap Areas

• Confusing DAE (nodal department) with the Ministry of Power — nuclear remains under DAE/PMO, not Ministry of Power.
• Assuming the SHANTI Act permits FDI in nuclear energy — it does not; FDI remains prohibited.
• Mixing up passage dates — Lok Sabha (17 Dec 2025) vs Rajya Sabha (18 Dec 2025) vs Presidential assent (20 Dec 2025).
• Confusing CLNDA, 2010 (liability law, now repealed) with the Atomic Energy Act, 1962 (the original governing framework, also repealed) — both were replaced, not just amended.
• Assuming AERB was always a statutory body — it was previously a subordinate regulatory authority; statutory status is new under the SHANTI Act.
