PARLIAMENT QUESTION: EXPANSION OF NUCLEAR POWER GENERATION CAPACITY

1. At a Glance

• Department of Atomic Energy (DAE) answered a Parliament Question on 19 March 2026 detailing India's installed nuclear capacity, generation trends, and the project pipeline [1].
• Topic intersects GS-III energy security, climate commitments (net-zero 2070), and the Nuclear Energy Mission announced in Union Budget 2025-26 [2][3].
• Tests aspirants on plant locations, reactor types (PHWR/LWR/PFBR/SMR/BSR), statutory framework (Atomic Energy Act 1962, CLNDA 2010), and capacity targets (22,480 MW by 2031-32, 100 GW by 2047) [1][2].

2. Why in the News

• PIB release dated 19 March 2026 by DAE quantified current capacity (8,780 MW), generation, and the 13,600 MW under implementation [1].
• Follows the Nuclear Energy Mission of Union Budget 2025-26 with a ₹20,000 crore SMR R&D outlay and a target of 5 indigenously designed SMRs operational by 2033 [2][3].

3. Background & Evolution

• 1948: Atomic Energy Commission set up; DAE created 1954 under the PM.
• Atomic Energy Act, 1962 — vests nuclear power exclusively with the Union (Entry 6, List I; Article 246).
• Three-stage nuclear programme (Homi Bhabha): Stage I PHWRs → Stage II FBRs (closed Pu-U cycle) → Stage III Thorium-U233.
• 2008: India-US 123 Agreement; NSG waiver opened civil nuclear trade.
• 2010: Civil Liability for Nuclear Damage Act (CLNDA) enacted.
• 2015: Fleet-mode approval for indigenous 700 MW PHWRs.
• Budget 2025-26: Nuclear Energy Mission with 100 GW@2047 vision [2][3].

4. Core Static Facts

• Implementing body: NPCIL (PHWR/LWR commercial fleet); BHAVINI (PFBR); under DAE (PM's portfolio) [1].
• Installed capacity: 8,780 MW across 24 reactors (excluding RAPS-1, 100 MW) [1].
• Generation: 45,855 MUs (2022-23) → 47,971 MUs (2023-24) → 56,681 MUs (2024-25) [1].
• Under implementation: 18 reactors, 13,600 MW = 10 under construction (incl. PFBR 500 MW) + 8 pre-project [1].
• Projects under construction: RAPP-8 (700), KKNPP-3&4 (2×1000), KKNPP-5&6 (2×1000), GHAVP-1&2 Gorakhpur Haryana (2×700), Kaiga-5&6 (2×700), PFBR Kalpakkam (500) [1].
• Targets: 22,480 MW by 2031-32; 100 GW by 2047 [2].
• Budget 2025-26: ₹20,000 cr for SMR R&D; 5 indigenous SMRs by 2033 [2][3].
• Bharat Small Reactor (BSR): 220 MW PHWR variant for captive use by steel/aluminium/metals [2].
• Statutes: Atomic Energy Act, 1962; CLNDA, 2010 (proposed amendments to enable private participation) [3].

5. Multi-Dimensional Analysis

Economic

• Nuclear contributes ~3% of installed capacity but offers high CUF (~80%) baseload, complementing variable RE [1].
• ₹20,000 cr SMR push to create domestic supply chain & industrial captive demand [2].

Environmental / Climate

• Low-carbon dispatchable power is critical for net-zero by 2070 and 500 GW non-fossil by 2030 (Panchamrit) [2].
• 56,681 MUs in 2024-25 displaces significant coal-CO₂ [1].

Strategic / Geopolitical

• Indigenous 700 MW PHWR fleet-mode reduces dependence on uranium imports tied to NSG-waiver-era safeguards.
• PFBR Kalpakkam marks transition to Stage II (closed fuel cycle), strategic for thorium roadmap [1].

Legal / Constitutional

• Atomic energy is Union subject (Entry 6, List I); states cannot legislate.
• CLNDA Sec 17(b) "supplier liability" cited as deterrent — amendment proposed to unlock private/foreign capital [3].

Scientific / Technological

• Reactor mix: indigenous PHWR (220/540/700 MW), Russian VVER LWRs (KKNPP), sodium-cooled FBR, and forthcoming SMR/BSR [1][2].

6. Recent Developments (last 12-18 months)

• Feb 2025: Union Budget 2025-26 announces Nuclear Energy Mission, ₹20,000 cr SMR R&D, 100 GW@2047 [2][3].
• 2024-25: Record generation 56,681 MUs, up ~18% YoY [1].
• 19 Mar 2026: DAE Parliament reply confirms 18 reactors / 13,600 MW pipeline [1].
• NPCIL JV proposals with NTPC (ASHVINI) and PSUs for BSR deployment [2].

7. Prelims Hooks

• Current installed nuclear capacity: 8,780 MW / 24 reactors (excl. RAPS-1) [1].
• RAPS-1 (100 MW) is excluded from count [1].
• PFBR at Kalpakkam = 500 MW, sodium-cooled, Stage II [1].
• Gorakhpur GHAVP is in Haryana (not UP) [1].
• KKNPP (Kudankulam) uses Russian VVER-1000 LWRs [1].
• Kaiga plant in Karnataka; units 5&6 are 700 MW PHWRs [1].
• 2024-25 nuclear generation: 56,681 MUs [1].
• Target capacity 2031-32: 22,480 MW; 2047: 100 GW [2].
• Bharat Small Reactor = 220 MW PHWR [2].
• SMR R&D outlay (Budget 2025-26): ₹20,000 crore; target 5 SMRs by 2033 [2][3].
• Implementing PSU: NPCIL (under DAE); FBR by BHAVINI [1].
• DAE reports directly to the Prime Minister (not MoP/MNRE).
• Statutory base: Atomic Energy Act, 1962; liability under CLNDA, 2010.

8. Mains Relevance

• GS-III: Energy security; Infrastructure-Energy; Science & Tech indigenisation; Environment-Climate change.
• GS-II: Statutory bodies & Centre-State (Union List Entry 6); CLNDA amendments.
• Probable stems:
• "Discuss the role of nuclear power in India's net-zero 2070 pathway. Examine constraints from CLNDA 2010."
• "Critically evaluate the Nuclear Energy Mission's reliance on Small Modular Reactors and Bharat Small Reactors."
• "Analyse progress of India's three-stage nuclear programme with reference to PFBR Kalpakkam."

10. Common Errors / Trap Areas

• Confusing GHAVP (Gorakhpur) Haryana with Gorakhpur, Uttar Pradesh.
• Counting RAPS-1 in installed capacity — it is excluded [1].
• Attributing nuclear to Ministry of Power / MNRE — it is under DAE/PMO.
• Mixing up PFBR (500 MW, BHAVINI) with PHWR fleet (NPCIL).
• Treating BSR (220 MW PHWR) as an SMR (<300 MW novel design) — both are pushed but technologically distinct.
• Saying private companies can own nuclear plants — currently barred by Atomic Energy Act 1962 (amendment proposed, not passed).
