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 [S1][S2].
Nuclear currently contributes only ~3.1 % of total electricity generation (FY 2024-25) — low base, ambitious target [S1].
Examinable intersection of GS-III (Energy, S&T) and GS-II (Centre–State, private participation, Atomic Energy Act amendments).

PIB release of 19 Mar 2026 by Department of Atomic Energy answering a Parliament Question on nuclear electricity share and capacity addition trajectory [S1].
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 [S2][S3].

Atomic Energy Act, 1962 — bars private/foreign ownership of nuclear plants; nuclear power is a Union subject (Entry 6, List I) under Article 246 [S2].
1954: Department of Atomic Energy created under direct charge of PM.
1987: NPCIL incorporated as PSU under DAE for commercial nuclear generation [S3].
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 [S2].
Feb 2025 (Union Budget 2025-26): Nuclear Energy Mission for Viksit Bharat announced; ₹20,000 cr R&D outlay [S2][S3].

Nodal body: Department of Atomic Energy (DAE), under PMO [S1].
Implementing PSUs: NPCIL (commercial reactors), BHAVINI (Fast Breeder), BARC (R&D — co-designing BSMR with NPCIL) [S2].
Installed capacity (excluding RAPS-1): 8.78 GW [S1].
Share in electricity mix (FY 2024-25): ~3.1 % [S1].
Capacity targets: 22 GW by 2031-32; 100 GW by 2047 [S1][S3].
Capacity-mix breakdown for 100 GW by 2047 [S3]:
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 [S2].
Bharat Small Reactor (BSR): 220 MW PHWR-based captive plants; NPCIL RfP to private industry [S2].
SMR target: 5 indigenous SMRs operational by 2033; outlay ₹20,000 crore [S2].
Recent commissioning: RAPP-7 (700 MW PHWR, Rawatbhata) synchronised to northern grid (2025); full power achieved [S3].

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 [S2].
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 [S2].
Federal / Administrative: Atomic Energy is Union List; land acquisition, water, R&R remain State subjects — bottleneck (Kovvada, Mithivirdi, Jaitapur delays).

Feb 2025: Nuclear Energy Mission announced in Union Budget 2025-26 with ₹20,000 cr R&D fund [S2][S3].
2025: RAPP-7 (700 MWe indigenous PHWR) synchronised to grid at Rawatbhata [S3].
2025: NPCIL floated Request-for-Proposal to private sector for BSR captive plants [S2].
2026 (Mar): DAE reaffirms 22 GW (2031-32) and 100 GW (2047) trajectory in Parliament [S1].

Nuclear share in FY 2024-25 electricity generation: ~3.1 % [S1].
Installed nuclear capacity (excl. RAPS-1): 8.78 GW [S1].
Capacity target 2031-32: 22 GW; 2047: 100 GW [S1].
Nuclear Energy Mission outlay: ₹20,000 crore; target 5 SMRs by 2033 [S2].
BSMR-200: 200 MWe; designed jointly by BARC + NPCIL [S2].
BSR: 220 MW PHWR-based captive plants for private industry [S2].
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 [S3].
Beyond 2032: NPCIL to add 32 GW (PHWR + LWR); 46 GW by non-NPCIL entities (PSEs, States, private, JVs) [S3].

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)

Atomic Energy Act, 1962 & CLNDA, 2010 — proposed amendments to enable private entry.
Three-Stage Nuclear Programme (Homi Bhabha) — PHWR → FBR → Thorium.
India–US 123 Agreement & NSG waiver (2008) — geopolitical backbone of imports.
Kudankulam, Jaitapur, Kovvada, Gorakhpur (GHAVP) — major project sites & delays.
Panchamrit pledges & Net-Zero 2070 — climate context for nuclear push.
Green Hydrogen Mission & PM-Surya Ghar — competing/complementary clean-energy missions.
IAEA safeguards & Additional Protocol — civil-military separation plan.
Thorium / Monazite reserves (Kerala, Odisha, AP) — long-term fuel security.

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.
