PARLIAMENT QUESTION: NUCLEAR ENERGY GENERATION

1. At a Glance

• DAE's reply to a Lok Sabha question (19 Mar 2026) restating India's roadmap to scale nuclear capacity from 8.78 GW (2026) → 22 GW by 2031-32 → 100 GW by 2047 under the Nuclear Energy Mission [1][2].
• Nuclear currently contributes only ~3.1 % of total electricity generation (FY 2024-25) — low base, ambitious target [1].
• Examinable intersection of GS-III (Energy, S&T) and GS-II (Centre–State, private participation, Atomic Energy Act amendments).

2. Why in the News

• PIB release of 19 Mar 2026 by Department of Atomic Energy answering a Parliament Question on nuclear electricity share and capacity addition trajectory [1].
• Follows the Union Budget 2025-26 announcement of a Nuclear Energy Mission with ₹20,000 crore for R&D of Small Modular Reactors (SMRs) and target of 5 indigenously developed SMRs operational by 2033 [2][3].

3. Background & Evolution

• Atomic Energy Act, 1962 — bars private/foreign ownership of nuclear plants; nuclear power is a Union subject (Entry 6, List I) under Article 246 [2].
• 1954: Department of Atomic Energy created under direct charge of PM.
• 1987: NPCIL incorporated as PSU under DAE for commercial nuclear generation [3].
• 2008: India–US 123 Agreement; NSG waiver unlocked imports of fuel/reactors.
• 2010: Civil Liability for Nuclear Damage Act.
• 2024-25 Budget: Policy directive to partner private sector for Bharat Small Reactors (BSR) — 220 MW PHWR captive plants [2].
• Feb 2025 (Union Budget 2025-26): Nuclear Energy Mission for Viksit Bharat announced; ₹20,000 cr R&D outlay [2][3].

4. Core Static Facts

• Nodal body: Department of Atomic Energy (DAE), under PMO [1].
• Implementing PSUs: NPCIL (commercial reactors), BHAVINI (Fast Breeder), BARC (R&D — co-designing BSMR with NPCIL) [2].
• Installed capacity (excluding RAPS-1): 8.78 GW [1].
• Share in electricity mix (FY 2024-25): ~3.1 % [1].
• Capacity targets: 22 GW by 2031-32; 100 GW by 2047 [1][3].
• Capacity-mix breakdown for 100 GW by 2047 [3]:
• NPCIL: existing 8.78 + 13 GW under implementation + 32 GW beyond 2032 (PHWR + LWR with foreign cooperation) = ~54 GW.

• Balance 46 GW: other PSEs, State Govts, private sector, JVs.

• Bharat Small Modular Reactor (BSMR-200): 200 MWe; BARC + NPCIL [2].

• Bharat Small Reactor (BSR): 220 MW PHWR-based captive plants; NPCIL RfP to private industry [2].
• SMR target: 5 indigenous SMRs operational by 2033; outlay ₹20,000 crore [2].
• Recent commissioning: RAPP-7 (700 MW PHWR, Rawatbhata) synchronised to northern grid (2025); full power achieved [3].

5. Multi-Dimensional Analysis

• Economic: Capital-intensive (~₹15-20 cr/MW); 100 GW target implies trillions in investment; opens captive nuclear for energy-intensive industry (steel, aluminium, refineries) under BSR model [2].
• Environmental / Climate: Critical to India's Panchamrit / Net-Zero by 2070 pledge; nuclear provides 24×7 low-carbon baseload — complements variable solar/wind.
• Strategic / Geopolitical: Requires Atomic Energy Act, 1962 and CLNDA, 2010 amendments to permit private/foreign equity; reactor imports from France (Jaitapur EPR), Russia (Kudankulam), US (Westinghouse) hinge on supplier-liability resolution.
• Scientific / Technological: Three-stage programme — PHWR → FBR (PFBR Kalpakkam, BHAVINI) → Thorium-U233; SMR R&D under Nuclear Energy Mission marks pivot to modular tech [2].
• Federal / Administrative: Atomic Energy is Union List; land acquisition, water, R&R remain State subjects — bottleneck (Kovvada, Mithivirdi, Jaitapur delays).

6. Recent Developments (last 12-18 months)

• Feb 2025: Nuclear Energy Mission announced in Union Budget 2025-26 with ₹20,000 cr R&D fund [2][3].
• 2025: RAPP-7 (700 MWe indigenous PHWR) synchronised to grid at Rawatbhata [3].
• 2025: NPCIL floated Request-for-Proposal to private sector for BSR captive plants [2].
• 2026 (Mar): DAE reaffirms 22 GW (2031-32) and 100 GW (2047) trajectory in Parliament [1].

7. Prelims Hooks

• Nuclear share in FY 2024-25 electricity generation: ~3.1 % [1].
• Installed nuclear capacity (excl. RAPS-1): 8.78 GW [1].
• Capacity target 2031-32: 22 GW; 2047: 100 GW [1].
• Nuclear Energy Mission outlay: ₹20,000 crore; target 5 SMRs by 2033 [2].
• BSMR-200: 200 MWe; designed jointly by BARC + NPCIL [2].
• BSR: 220 MW PHWR-based captive plants for private industry [2].
• Nodal department: Department of Atomic Energy, under PMO (not Ministry of Power, not MNRE).
• Atomic Energy is Entry 6, List I (Union List).
• Statutory base: Atomic Energy Act, 1962; liability: CLNDA, 2010.
• Fast Breeder Reactor operator: BHAVINI (Bharatiya Nabhikiya Vidyut Nigam Ltd.) — not NPCIL.
• RAPP-7 (Rawatbhata, Rajasthan): indigenous 700 MWe PHWR, synchronised to northern grid in 2025 [3].
• Beyond 2032: NPCIL to add 32 GW (PHWR + LWR); 46 GW by non-NPCIL entities (PSEs, States, private, JVs) [3].

8. Mains Relevance

• GS-III — Energy (infrastructure), Science & Technology, Climate change.
• GS-II — Government policies & interventions; Centre–State on land/water.
• Question stems:
• "Examine the role of nuclear energy in India's net-zero pathway. Discuss the institutional, legal, and financial reforms needed to achieve the 100 GW by 2047 target." (GS-III)
• "Small Modular Reactors are projected as a 'game-changer' for India's energy transition. Critically analyse." (GS-III)
• "Discuss the rationale and challenges of opening up India's nuclear sector to private and foreign participation." (GS-II/III)

10. Common Errors / Trap Areas

• Nodal body is DAE under PMO, NOT Ministry of Power or MNRE.
• NPCIL ≠ BHAVINI: NPCIL runs PHWRs/LWRs; BHAVINI runs Fast Breeder Reactor (Kalpakkam).
• BSMR (200 MWe) vs BSR (220 MW PHWR) — distinct: BSMR is a new SMR design; BSR is captive PHWR for industry.
• Nuclear share is ~3.1 % of electricity generation, not of installed capacity (installed share ~1.8 %).
• 8.78 GW figure excludes RAPS-1 (under decommissioning).
• 100 GW by 2047 is a roadmap target, not a sanctioned project pipeline — distinguish in answers.
