PARLIAMENT QUESTION: NUCLEAR POWER 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 [1].
• Government target: 100 GW nuclear capacity by 2047, with capacity to triple by 2031-32 [1][3].
• 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 [4][5].
• 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 [1].
• Union Minister Dr. Jitendra Singh told Rajya Sabha that installed nuclear capacity is set to triple by 2031-32 under fast-track expansion [3].
• 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 [5].

3. Background & Evolution

• Three-stage programme conceptualised by Dr. Homi J. Bhabha in the 1950s, based on a closed fuel cycle [1].
• Stage 1: Natural uranium fuels Pressurised Heavy Water Reactors (PHWRs) [1].
• Stage 2: Plutonium (from reprocessed PHWR spent fuel) fuels Fast Breeder Reactors (FBRs) [1].
• Stage 3: Large-scale thorium utilisation via Uranium-233 bred in reactors using plutonium, only after adequate FBR capacity is achieved [1].
• 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 [4].

4. Core Static Facts

5. Multi-Dimensional Analysis

Economic

• ₹20,000 crore SMR mission signals large capital push; private investment expected once legal amendments pass [4][5].
• Reduced uranium import dependency lowers forex outflow and exposure to supplier-nation politics [1].

Scientific/Technological

• Closed fuel cycle enables near-complete utilisation of fissile material via reprocessing [1].
• SMRs represent a technological shift toward modular, faster-deployable reactors [4].

Legal/Constitutional

• Atomic Energy Act, 1962 currently restricts private ownership of nuclear plants — under review for amendment [5].
• Civil Liability for Nuclear Damage Act, 2010 amendment needed to attract foreign/private nuclear suppliers and operators [5].

Geopolitical/Strategic

• Thorium reliance is a strategic hedge — India holds among the world's largest thorium reserves, reducing dependence on imported enriched uranium [1].
• Energy security framed explicitly against "geopolitical risk" in the DAE's own language [1].

Governance/Administrative

• Multi-agency Task Force (DAE, AERB, NPCIL, NITI Aayog, MoLJ, MEA) reflects complexity of opening a historically state-monopoly sector [5].
• Phased capacity targets (2031-32 → 2037 → 2042 → 2047) show a structured administrative roadmap [2].

6. Recent Developments (last 12-18 months)

• 23 July 2026: Parliament Question on Nuclear Power Programme reaffirms three-stage strategy and thorium rationale [1].
• February 2026: DAE factsheet "A New Chapter in India's Nuclear Journey" details capacity roadmap [2].
• Rajya Sabha statement by Dr. Jitendra Singh confirming capacity to triple by 2031-32 [3].
• Union Budget 2025-26: Nuclear Energy Mission launched with SMR focus and ₹20,000 crore allocation [4].
• DAE Task Force formed to draft Atomic Energy Act and Civil Liability for Nuclear Damage Act amendments enabling private participation [5].

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.
