PARLIAMENT QUESTION: NUCLEAR POWER PROGRAMME
I have sufficient grounded facts from Tier-1 sources. Writing the study note.
Nuclear Power Programme (India's Three-Stage Programme)
1. At a Glance
- India runs a three-stage nuclear power programme designed to leverage vast thorium reserves while domestic uranium is limited, insulating energy security from geopolitical/import risk [S1].
- Government target: 100 GW nuclear capacity by 2047, with capacity to triple by 2031-32 [S1][S3].
- Union Budget 2025-26 launched the Nuclear Energy Mission, including a push for Small Modular Reactors (SMRs) and legislative reform to allow private sector participation [S4][S5].
- High-yield UPSC topic bridging Science & Tech (GS-III), energy security, and legislative reform (GS-II).
2. Why in the News
- Parliament Question (Lok Sabha/Rajya Sabha) dated 23 July 2026 reiterated DAE's rationale for the three-stage programme — reducing import dependency on uranium and geopolitical risk insulation [S1].
- Union Minister Dr. Jitendra Singh told Rajya Sabha that installed nuclear capacity is set to triple by 2031-32 under fast-track expansion [S3].
- DAE Task Force actively examining amendments to the Atomic Energy Act, 1962 and Civil Liability for Nuclear Damage Act, 2010 to enable private sector build-own-operate models [S5].
3. Background & Evolution
- Three-stage programme conceptualised by Dr. Homi J. Bhabha in the 1950s, based on a closed fuel cycle [S1].
- Stage 1: Natural uranium fuels Pressurised Heavy Water Reactors (PHWRs) [S1].
- Stage 2: Plutonium (from reprocessed PHWR spent fuel) fuels Fast Breeder Reactors (FBRs) [S1].
- Stage 3: Large-scale thorium utilisation via Uranium-233 bred in reactors using plutonium, only after adequate FBR capacity is achieved [S1].
- Union Budget 2025-26: Nuclear Energy Mission announced with ₹20,000 crore outlay for SMR R&D, targeting five indigenously designed operational SMRs by 2033 [S4].

5. Multi-Dimensional Analysis
Economic - ₹20,000 crore SMR mission signals large capital push; private investment expected once legal amendments pass [S4][S5]. - Reduced uranium import dependency lowers forex outflow and exposure to supplier-nation politics [S1].
Scientific/Technological - Closed fuel cycle enables near-complete utilisation of fissile material via reprocessing [S1]. - SMRs represent a technological shift toward modular, faster-deployable reactors [S4].
Legal/Constitutional - Atomic Energy Act, 1962 currently restricts private ownership of nuclear plants — under review for amendment [S5]. - Civil Liability for Nuclear Damage Act, 2010 amendment needed to attract foreign/private nuclear suppliers and operators [S5].
Geopolitical/Strategic - Thorium reliance is a strategic hedge — India holds among the world's largest thorium reserves, reducing dependence on imported enriched uranium [S1]. - Energy security framed explicitly against "geopolitical risk" in the DAE's own language [S1].
Governance/Administrative - Multi-agency Task Force (DAE, AERB, NPCIL, NITI Aayog, MoLJ, MEA) reflects complexity of opening a historically state-monopoly sector [S5]. - Phased capacity targets (2031-32 → 2037 → 2042 → 2047) show a structured administrative roadmap [S2].
6. Recent Developments (last 12-18 months)
- 23 July 2026: Parliament Question on Nuclear Power Programme reaffirms three-stage strategy and thorium rationale [S1].
- February 2026: DAE factsheet "A New Chapter in India's Nuclear Journey" details capacity roadmap [S2].
- Rajya Sabha statement by Dr. Jitendra Singh confirming capacity to triple by 2031-32 [S3].
- Union Budget 2025-26: Nuclear Energy Mission launched with SMR focus and ₹20,000 crore allocation [S4].
- DAE Task Force formed to draft Atomic Energy Act and Civil Liability for Nuclear Damage Act amendments enabling private participation [S5].
7. Prelims Hooks
- Three-stage nuclear programme conceived by Homi J. Bhabha.
- Stage 1 uses natural uranium in PHWRs.
- Stage 2 uses plutonium (from reprocessed PHWR spent fuel) in Fast Breeder Reactors (FBRs).
- Stage 3 uses Uranium-233 bred from thorium.
- Nodal department: Department of Atomic Energy (DAE), not Ministry of Power.
- Target: 100 GW nuclear capacity by 2047.
- Intermediate targets: 47 GW by 2037, 67 GW by 2042.
- Capacity projected to triple by 2031-32 (~22,380 MW).
- 10 new reactors (8,000 MW) under construction across Gujarat, Rajasthan, Tamil Nadu, Haryana, Karnataka, Madhya Pradesh.
- Nuclear Energy Mission announced in Union Budget 2025-26 with ₹20,000 crore for SMR R&D.
- Target of 5 indigenous SMRs operational by 2033.
- Amendments proposed to Atomic Energy Act, 1962 and Civil Liability for Nuclear Damage Act, 2010 to allow private sector participation.
- DAE Task Force includes AERB, NPCIL, NITI Aayog, MoLJ, MEA.
- India's programme is based on a closed fuel cycle.
- Thorium is a fertile material, not fissile — must be converted to fissile U-233.
8. Mains Relevance
- GS-III: Science & Technology — indigenous technology development; achievements of Indians in science; energy security.
- GS-II: Government policies and interventions; legislative reform for sectoral opening.
- Possible question stems:
- "Discuss the rationale behind India's three-stage nuclear power programme. How does thorium utilisation address India's long-term energy security?"
- "Examine the significance of the Nuclear Energy Mission announced in Union Budget 2025-26 in achieving India's 100 GW nuclear capacity target by 2047."
- "What legislative reforms are necessary to enable private sector participation in India's nuclear power sector? Discuss associated challenges."

10. Common Errors / Trap Areas
- Confusing nodal ministry: it is DAE (Department of Atomic Energy), directly under the Prime Minister, NOT Ministry of Power or MNRE.
- Mixing up stage sequence: Stage 2 uses plutonium in FBR, not thorium directly; thorium enters only in Stage 3.
- Confusing fissile vs fertile: uranium-235/plutonium-239/U-233 are fissile; thorium-232 is fertile, requiring conversion.
- Conflating Nuclear Energy Mission (2025-26, SMR-focused) with the older three-stage programme — the Mission is a modern funding/policy vehicle, not a replacement of the original Bhabha framework.
- Misremembering capacity target years — 2031-32 (triple), 2037 (47 GW), 2042 (67 GW), 2047 (100 GW) are distinct milestones, easily jumbled in MCQs.
