PARLIAMENT QUESTION: POWER PRODUCTION FROM NUCLEAR ENERGY

1. At a Glance

• Department of Atomic Energy (DAE) update in Lok Sabha on 04 Feb 2026 on the status, projections, and policy stance of India's nuclear power sector [1].
• 24 operational reactors, 8,780 MW — small (~3%) but strategically critical share of India's installed electricity capacity [1].
• Anchors a larger Nuclear Energy Mission (Budget 2025-26) targeting 100 GW by 2047, central to GS-III energy security & climate transition [2][3].

2. Why in the News

• 04 Feb 2026 — DAE reply in Parliament: 24 plants (8,780 MW); a Sub-Committee of the Standing Site Selection Committee (CEA + NPCIL + AERB) constituted to examine retiring thermal power plant sites for nuclear conversion [1].
• Peak demand projected to 446 GW and energy requirement 3,215 BU by 2034-35 [1].
• No proposal yet to replace thermal capacity wholesale with nuclear [1].

3. Background & Evolution

• 1948: Atomic Energy Act (Act of 1948, replaced by 1962); DAE created 1954 under PM directly.
• 3-stage nuclear programme of Homi Bhabha: PHWR (natural U) → FBR (Pu) → Thorium-U233.
• 1969: Tarapur (TAPS-1&2), India's first commercial nuclear plant (BWR, US cooperation).
• 2008: Indo-US 123 Agreement and NSG waiver opened civil nuclear commerce.
• 2010: Civil Liability for Nuclear Damage (CLND) Act.
• 2023: Govt. announced expansion from 7,480 MW → 22,480 MW by 2031-32 [4].
• Feb 2025: Nuclear Energy Mission announced in Union Budget with ₹20,000 cr outlay for SMR R&D [2][3].

4. Core Static Facts

• Operational reactors: 24 (RAPS-1 in extended shutdown, excluded) [1].
• Installed nuclear capacity: 8,780 MW [1].
• 2031-32 target: 22,480 MW [4].
• 2047 target: 100 GW under Nuclear Energy Mission; NPCIL share 54 GW [2][3].
• Budget outlay (Mission): ₹20,000 crore for SMR R&D [3].
• Target — 5 indigenous SMRs operational by 2033 [3].
• Implementing body: Nuclear Power Corporation of India Ltd (NPCIL), PSU under DAE.
• Regulator: Atomic Energy Regulatory Board (AERB), est. 1983.
• Sub-Committee on site selection: CEA + NPCIL + AERB [1].
• Enabling Acts: Atomic Energy Act, 1962; CLND Act, 2010 (amendments proposed) [3].
• Projected 2034-35 demand: peak 446 GW, energy 3,215 BU [1].
• SMR variants under DAE: BSMR-200 (lead unit at Tarapur, Maharashtra), SMR-55, HTGCR (5 MWth) for hydrogen [3].

5. Multi-Dimensional Analysis

Economic

• Nuclear is capital-intensive but offers low LCOE over a 60-year reactor life.
• Tariff-free baseload power supports manufacturing competitiveness; ₹20,000 cr SMR R&D signals industrial-policy use of nuclear [3].

Environmental / Climate

• Zero direct CO₂ emissions; key for India's net-zero by 2070 pledge.
• Converting retiring thermal sites (coal-fired) for nuclear leverages existing grid, water, land infrastructure [1].

Scientific / Technological

• SMRs (50–300 MW) — factory-built, scalable, suited for remote/industrial captive use.
• BSMR-200 to be hosted at Tarapur [3]; HTGCR enables green hydrogen.
• 3-stage programme's Fast Breeder Reactor (PFBR Kalpakkam) is the bridge to thorium utilisation.

Legal / Governance

• Proposed amendments to Atomic Energy Act, 1962 and CLND Act, 2010 to permit private-sector participation [3].
• CLND Act's supplier-liability clause (Sec 17(b)) historically deterred foreign vendors.

Geopolitical / Strategic

• India outside NPT; relies on NSG waiver (2008) for fuel imports (Russia, France, Kazakhstan).
• Kudankulam (Russia), Jaitapur (France-EDF EPR), and US SMR cooperation post-2023 reviewed in this context.

6. Recent Developments (12-18 months)

• Sep 2024: RAPP-7 (Rajasthan, 700 MW indigenous PHWR) achieved first criticality [S5-style PIB doc; see S2 search list].
• Feb 2025: Union Budget unveils Nuclear Energy Mission, ₹20,000 cr; targets 5 SMRs by 2033, 100 GW by 2047 [2][3].
• 2025-26: Parliament Q&A reaffirm BSMR-200 advancing toward sanction; SMR-55 and HTGCR under design [3].
• 04 Feb 2026: Sub-Committee formed to evaluate retiring thermal sites for nuclear repurposing [1].

7. Prelims Hooks

• India has 24 operational nuclear reactors with 8,780 MW as of Feb 2026 [1].
• RAPS-1 is excluded as it is under extended shutdown [1].
• Sub-Committee for thermal-site repurposing has officers from CEA, NPCIL, and AERB — not MoP alone [1].
• Projected peak demand 446 GW and energy 3,215 BU in 2034-35 [1].
• Nuclear Energy Mission outlay: ₹20,000 crore (Budget 2025-26) [3].
• Target: 100 GW nuclear by 2047; NPCIL share 54 GW [2][3].
• At least 5 indigenously developed SMRs operational by 2033 [3].
• BSMR-200 lead unit proposed at Tarapur Atomic Power Station, Maharashtra [3].
• DAE SMR designs: BSMR-200, SMR-55, HTGCR (5 MWth, for hydrogen) [3].
• 2031-32 capacity target: 22,480 MW (up from earlier 7,480 MW) [4].
• Enabling laws to be amended: Atomic Energy Act 1962 & CLND Act 2010 [3].
• NPCIL is the operating utility; AERB is the safety regulator.

8. Mains Relevance

• GS-III: Energy security, infrastructure, climate change mitigation, S&T indigenisation.
• GS-II: Government policies & interventions (Nuclear Energy Mission); bilateral nuclear cooperation.
• Syllabus heading: "Infrastructure: Energy, Ports, Roads…"; "Science and Technology – indigenization of technology and developing new technology."

Plausible question stems

1. "Examine the role of Small Modular Reactors (SMRs) in India's energy transition. What legal and institutional reforms are required to scale nuclear power?"
2. "Discuss the rationale and feasibility of repurposing retiring thermal power plant sites for nuclear power generation in India."
3. "India's Nuclear Energy Mission aims at 100 GW by 2047. Critically analyse the technological, financial, and regulatory challenges."

10. Common Errors / Trap Areas

• 8,780 MW is operational; 7,480 MW is an older base figure quoted in 2023 expansion announcements — don't conflate [1][4].
• AERB regulates; NPCIL operates; DAE is the parent department — distinct roles.
• The Nuclear Energy Mission targets 100 GW by 2047, not 2030 or 2035.
• The Sub-Committee is under the Standing Site Selection Committee, not a new statutory body [1].
• Tarapur, not Kudankulam, is the proposed lead site for BSMR-200 [3].
• RAPS-1 exclusion is due to extended shutdown, not decommissioning [1].
