PARLIAMENT QUESTION: DOMESTIC NUCLEAR POWER GENERATION

1. At a Glance

• Nuclear power is a clean, base-load, 24×7 source central to India's energy security and the net-zero by 2070 commitment [S1].
• Domestic programme rests on Dr. Homi Bhabha's indigenous three-stage nuclear power programme (PHWR → FBR → Thorium-U233) [S1][S4].
• Examinable for GS-III (Energy, Science & Tech) and GS-II (Government Policies) — the Nuclear Energy Mission (Budget 2025-26) is a current-affairs anchor [S2][S3].

2. Why in the News

• Nuclear Energy Mission announced in Union Budget 2025-26 with target of 100 GWe by 2047 [S1][S2][S3].
• ₹20,000 crore outlay for R&D, design and deployment of Small Modular Reactors (SMRs); at least 5 indigenous SMRs operational by 2033 [S2][S3].
• Lok Sabha/Rajya Sabha reply (04 Feb 2026) by Department of Atomic Energy reiterated capacity build-up [S1].
• RAPP-7 (700 MW PHWR) achieved first criticality (Sep 2024); KAPS-3 reached full power — indigenous 700 MW PHWR fleet expansion [S4][S5].

3. Background & Evolution

• 1948: Atomic Energy Commission established; 1954: Department of Atomic Energy (DAE) created under the PM [S4].
• Atomic Energy Act, 1962: governing statute; nuclear is a Union List subject [S4].
• 1969: Tarapur-1 & 2 (BWRs, US-supplied) — first commercial reactors [S4].
• 1987: NPCIL incorporated under Companies Act; BHAVINI (2003) for fast breeder reactors [S4].
• 2008: Indo-US 123 Agreement → NSG waiver, civil nuclear cooperation [S4].
• 2010: Civil Liability for Nuclear Damage Act (CLNDA) [S4].
• 2025-26: Nuclear Energy Mission; proposed amendments to Atomic Energy Act and CLNDA to enable private sector participation [S2][S3].

4. Core Static Facts

• Implementing body: Department of Atomic Energy (DAE), directly under Prime Minister; operator NPCIL; FBR operator BHAVINI; regulator AERB; R&D body BARC [S1][S4].
• Installed capacity: 8,780 MW across 24 reactors (as per recent PIB factsheet) [S5].
• Under construction/implementation: 18 reactors / 13,600 MW, to be commissioned by 2031-32 [S5].
• Target: 100 GWe by 2047 (current ~8.78 GW) [S1][S2].
• SMR allocation: ₹20,000 crore; 5 indigenous SMRs by 2033 [S2][S3].
• Reactor types under development at BARC: BSMR-200 (200 MWe), SMR-55 (55 MWe), High-Temperature Gas-Cooled Reactor ~5 MWth [S2].
• Bharat Small Reactor (BSR): 220 MW PHWR variant for captive use by steel/aluminium/metals industry [S2].
• Kudankulam (Tamil Nadu): VVER-1000 Russian design; Units 1 & 2 (2×1000 MW) operational; Units 3-6 under construction → site target 6,000 MW [S5].
• RAPP-7 & 8 (Rawatbhata, Rajasthan): 2×700 MW indigenous PHWR; RAPP-7 attained criticality Sep 2024 [S4][S5].
• Enabling law: Atomic Energy Act, 1962; CLNDA, 2010; international: IAEA Additional Protocol (2014) [S4].

5. Multi-Dimensional Analysis

Economic - Capex-heavy but offers low lifecycle cost and stable base-load vs. variable renewables [S1]. - ₹20,000 cr SMR push expected to crowd in private capital once CLNDA & AE Act amendments pass [S2][S3].

Environmental - Lifecycle emissions of nuclear are among the lowest, comparable to wind, lower than solar PV [S1]. - Reduces fossil-fuel dependence; aligns with Panchamrit & Net-Zero 2070 pledges (COP26) [S1].

Scientific / Technological - Three-stage programme: Stage-1 PHWR (natural U) → Stage-2 FBR using Pu-239 (PFBR Kalpakkam under commissioning) → Stage-3 Thorium-U233 cycle leveraging India's vast monazite reserves [S1][S4]. - Indigenous 700 MW PHWR fleet (KAPS-3/4, RAPP-7/8) demonstrates self-reliance [S4][S5].

Geopolitical / Strategic - Post-2008 NSG waiver enables fuel imports (Russia, France, Kazakhstan, Canada) [S4]. - NSG / CTBT non-membership still constrains certain transfers [S4].

Legal / Constitutional - Atomic energy is Entry 6, Union List; civilian liability capped under CLNDA §6 with operator's right of recourse under §17(b) — a deterrent to foreign vendors being reconsidered [S4].

Administrative - DAE attached offices: NPCIL, BHAVINI, NFC, HWB, IGCAR; bottleneck: long gestation & land acquisition; mitigated by co-locating BSRs near industrial clusters [S2].

6. Recent Developments (last 12-18 months)

• 04 Feb 2026: DAE Parliament reply restating Nuclear Energy Mission & 100 GWe-by-2047 target [S1].
• Feb 2025: Union Budget 2025-26 announces Nuclear Energy Mission, ₹20,000 cr SMR R&D [S2][S3].
• Sep 2024: RAPP-7 achieved first criticality; KAPS-3 & 4 at full power [S4][S5].
• Government signals amendments to Atomic Energy Act 1962 and CLNDA 2010 to permit private investment [S2][S3].

7. Prelims Hooks

• Atomic Energy is Entry 6, Union List under Atomic Energy Act, 1962 [S4].
• India's installed nuclear capacity: 8,780 MW / 24 reactors [S5].
• Target: 100 GWe by 2047 under Nuclear Energy Mission (Budget 2025-26) [S1][S2].
• SMR allocation: ₹20,000 crore; 5 SMRs by 2033 [S2][S3].
• NPCIL operates reactors; BHAVINI handles Fast Breeder Reactors [S4].
• Regulator: Atomic Energy Regulatory Board (AERB) — NOT MoEFCC [S4].
• Kudankulam uses Russian VVER-1000, located in Tirunelveli district, Tamil Nadu [S5].
• RAPP-7 (Rawatbhata, Rajasthan) — 700 MW indigenous PHWR, criticality Sep 2024 [S4][S5].
• Three-stage programme authored by Homi Bhabha: PHWR → FBR → Thorium [S1][S4].
• Civil liability statute: CLNDA, 2010 [S4].
• India's net-zero target year: 2070 (COP26, Glasgow) [S1].
• BSR = 220 MW PHWR variant for industrial captive use [S2].
• BARC designs: BSMR-200, SMR-55, HTGR-5 MWth [S2].
• KKNPP eventual capacity at full build-out: 6,000 MW (6 × 1000 MW) [S5].
• Total reactors under implementation: 18 reactors / 13,600 MW; commissioning by 2031-32 [S5].

8. Mains Relevance

• GS-III: "Infrastructure: Energy" + "Science & Technology — Indigenisation, Achievements of Indians in S&T."
• GS-II: Government Policies — schemes (Nuclear Energy Mission); also Bilateral Agreements (Indo-US 123).
• Plausible question stems: 1. "Examine the rationale and feasibility of India's target of 100 GWe nuclear capacity by 2047. What legal and institutional reforms are required?" 2. "Small Modular Reactors offer a paradigm shift in nuclear deployment. Discuss with reference to India's Nuclear Energy Mission." 3. "Critically evaluate the Civil Liability for Nuclear Damage Act, 2010 in the context of attracting foreign investment in India's nuclear sector."

9. Related Topics to Study Next

• Civil Liability for Nuclear Damage Act, 2010 — supplier liability §17(b) debate.
• Indo-US 123 Agreement & NSG waiver (2008) — basis of civil nuclear trade.
• Prototype Fast Breeder Reactor (PFBR), Kalpakkam — Stage 2 of three-stage plan.
• Thorium fuel cycle & monazite sands of Kerala/Odisha — Stage 3 resource base.
• Panchamrit pledges & Net-Zero 2070 — climate-energy nexus.
• AERB & IAEA Additional Protocol (2014) — safeguards architecture.
• Renewables targets (500 GW non-fossil by 2030) — comparative energy basket.
• Uranium mining (UCIL, Jaduguda; Tummalapalle reserves) — fuel security.

10. Common Errors / Trap Areas

• Regulator confusion: AERB regulates nuclear safety — not MoEFCC or CEA.
• NPCIL vs BHAVINI: NPCIL = PHWRs/LWRs (commercial); BHAVINI = Fast Breeder Reactors only.
• Target year mix-up: Nuclear capacity target is 100 GWe by 2047 (not 2030 or 2070). Net-zero is 2070.
• Stage-3 fuel: Uses U-233 bred from Thorium, not Thorium directly as fissile material.
• CLNDA cap: Operator liability is limited; right of recourse against suppliers (§17b) is the contested clause — not §6.
• KKNPP origin: Russian-supplied VVER, not French EPR or US AP-1000 (those are Jaitapur/Kovvada).
