PARLIAMENT QUESTION: NUCLEAR POWER GENERATION CAPACITY

In this note

1. At a Glance

India's installed nuclear power capacity stands 8,780 MW across 24 reactors, contributing ~3.1% of total electricity generation (2025-26) [1].
Roadmap targets tripling capacity to 22,380 MW by 2031-32, then 100 GW by 2047 via Nuclear Energy Mission [1][2].
UPSC angle: tests energy mix, PSU (NPCIL) role, Nuclear Energy Mission (Budget 2025-26), SMR push, and Rajasthan/Tamil Nadu/Haryana project geography.

PIB press release dated 29 Jul 2026 answering Parliament Question on installed capacity, under-construction projects (RAPP-8, KKNPP-3&4, KKNPP-5&6, Gorakhpur), and physical progress as of June 2026 [1].

Capacity grew from 4,780 MW (2014) to 8,780 MW currently [2].
Union Budget 2025-26 announced Nuclear Energy Mission with ₹20,000 crore outlay for Small Modular Reactors (SMRs), target: 5 indigenous SMRs operational by 2033 [2].
Staged roadmap: 22,380 MW (2031-32) → 47 GW (2037) → 67 GW (2042) → 100 GW (2047) [2].
Beyond 2032, additional 32 GW envisaged by NPCIL (indigenous PHWR + foreign-cooperation LWR), taking capacity to ~54 GW [1].

Nodal ministry/dept: Department of Atomic Energy (DAE), under PMO [1].
Implementing PSU: Nuclear Power Corporation of India Limited (NPCIL) [1].
Current capacity: 8,780 MW / 24 plants [1].
Nuclear share in generation: 3.1% (2025-26) [1].
Under-construction (as of June 2026): RAPP-8 (Rajasthan, 1x700 MW, 96.26%, expected operational 2026); KKNPP-3&4 (Tamil Nadu, 2x1000 MW, 82.65%, due June 2027/2028); KKNPP-5&6 (2x1000 MW, 45%, due June 2029/March 2030); Gorakhpur, Haryana project also under construction [1].
10-reactor tranche: 8,000 MW under construction across Gujarat, Rajasthan, Tamil Nadu, Haryana, Karnataka, Madhya Pradesh; pre-project activity for 10 more reactors ongoing [2].
SMR outlay: ₹20,000 crore, Budget 2025-26 [2].

Economic

Large capex commitment (₹20,000 cr for SMRs alone) signals energy-security-driven public investment push [2].
Diversifies power mix away from coal-import/emission exposure.

Environmental

Nuclear framed as low-carbon baseload, supports India's net-zero-by-2070 and clean energy transition narrative [1].

Scientific/Technological

SMR indigenous design push — shift from large PHWR to modular reactors for flexibility [2].
Mix of indigenous 700 MW PHWR and foreign-cooperation 1000 MW LWR (Kudankulam, Russia-assisted) [1].

Geopolitical/Strategic

KKNPP units built with international cooperation — reflects civil nuclear cooperation post-2008 NSG waiver era.
Foreign-cooperation LWRs beyond 2032 imply continued reliance on external reactor technology partners [1].

Administrative

Multi-state execution (Rajasthan, Tamil Nadu, Haryana, Gujarat, Karnataka, MP) — center-driven, DAE/NPCIL retains full control (unlike power sector's federal generation-transmission-distribution split) [1][2].
Long lead times (KKNPP-5&6 progress only 45% against multi-year timeline) show execution bottlenecks typical of nuclear projects.

29 Jul 2026: PIB Parliament Question reply confirms 8,780 MW/24 plants, details RAPP-8, KKNPP-3&4/5&6, Gorakhpur progress [1].
2025-26 Union Budget: Nuclear Energy Mission launched with ₹20,000 crore SMR outlay, target 5 SMRs by 2033 [2].
Rajya Sabha statement (Dr. Jitendra Singh): capacity to triple by 2031-32 [2].

Current installed nuclear capacity: 8,780 MW across 24 plants [1].
Nuclear share in electricity generation (2025-26): 3.1% [1].
Target capacity by 2031-32: 22,380 MW [2].
Target by 2037: 47 GW; by 2042: 67 GW; by 2047: 100 GW [2].
Nodal department: Department of Atomic Energy (DAE) [1].
Implementing agency: NPCIL (Nuclear Power Corporation of India Limited) [1].
RAPP-8 located in Rajasthan, capacity 700 MW, ~96.26% physical progress, expected 2026 [1].

KKNPP-5&6, 2x1000 MW, due June 2029/March 2030 [1].
Gorakhpur project located in Haryana (not UP) — common trap [1].
Capacity in 2014 was 4,780 MW — shows growth trajectory [2].
Nuclear Energy Mission announced in Union Budget 2025-26 [2].
SMR outlay: ₹20,000 crore; target 5 indigenous SMRs by 2033 [2].

GS-III: Infrastructure — Energy; Science & Technology — indigenization, nuclear technology.
Syllabus heading: "Infrastructure: Energy" / "Achievements of Indians in Science & Technology; indigenization of technology".
Possible stems: 1. "Discuss the role of nuclear energy in India's clean energy transition. Examine challenges in scaling up nuclear capacity to meet 2047 targets." (GS-III) 2. "Small Modular Reactors are being projected as a game-changer in India's nuclear strategy. Analyze." (GS-III) 3. "Evaluate India's civil nuclear cooperation with foreign partners in context of capacity expansion goals." (GS-II/III)

Nuclear Energy Mission (Budget 2025-26) — parent policy driving current targets.
Small Modular Reactors (SMRs) — new technology thrust, ₹20,000 cr outlay.
Civil Liability for Nuclear Damage Act, 2010 — legal bottleneck often cited for slow foreign investment.
India's NSG waiver (2008) and civil nuclear agreements (US, Russia, France) — geopolitical backdrop for KKNPP/foreign-cooperation reactors.
National Green Hydrogen Mission / India's net-zero 2070 pledge — broader clean energy context.
Integrated Energy Policy / National Electricity Plan — overall power-sector planning linkage.
Uranium/Thorium fuel cycle, Fast Breeder Reactor programme — India's 3-stage nuclear programme (Bhabha's plan).

Confusing installed capacity (8,780 MW) with generation share (3.1%) — different metrics, don't conflate.
Assuming Gorakhpur nuclear project is in Uttar Pradesh — it is in Haryana.
Mixing up interim target (22,380 MW by 2031-32) with final Mission target (100 GW by 2047).
Attributing Nuclear Energy Mission to Ministry of Power — it's under Department of Atomic Energy, announced via Union Budget.
Confusing NPCIL (PSU executing projects) with DAE (policy-making department).
