PARLIAMENT QUESTION: ENHANCING NUCLEAR ENERGY
I now have sufficient facts from Tier 1 (pib.gov.in) sources. Writing the study note.
1. At a Glance
- India has set a 100 GW nuclear power capacity target by 2047, announced under the Nuclear Energy Mission in Union Budget 2025-26 [S1].
- Strategy rests on a two-pronged approach: large indigenous/imported reactors at greenfield sites + Small Modular Reactors (SMRs) for brownfield sites (retiring fossil plants, captive industrial power, off-grid use) [S1].
- Relevant for UPSC as it links energy security, Net Zero 2070 commitment, Viksit Bharat vision, and private-sector participation in a historically state-monopoly sector [S1].
- Recently reinforced by a major legislative overhaul (SHANTI Act, 2025) — high-yield current-affairs + polity crossover topic.
2. Why in the News
- 30 July 2026: PIB press release "Parliament Question: Enhancing Nuclear Energy" reiterated the roadmap to 100 GW by 2047 in response to a Parliament question to the Department of Atomic Energy (DAE) [S1].
- Follows enactment of the SHANTI Act, 2025 (Winter Session 2025), which consolidated/replaced the Atomic Energy Act, 1962 and Civil Liability for Nuclear Damage Act, 2010 [S6].
3. Background & Evolution
- India's nuclear programme originated under Homi J. Bhabha, with the Atomic Energy Act, 1962 as the original governing statute [S1][S6].
- Civil Liability for Nuclear Damage Act, 2010 (CLND Act) later governed operator/supplier liability, long cited as a deterrent to foreign private investment [S6].
- Union Budget 2025-26 (Feb 2025): Finance Minister announced the Nuclear Energy Mission with ₹20,000 crore allocation for SMR R&D and deployment; target of at least 5 indigenously designed SMRs operational by 2033 [S2][S4].
- Winter Session 2025: Parliament enacted the SHANTI Act, 2025 (Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India), repealing/consolidating the 1962 and 2010 Acts into a unified framework, opening the sector to private participation [S6].
- 30 July 2026: Latest parliamentary reiteration of the 100 GW/2047 roadmap [S1].

5. Multi-Dimensional Analysis
Economic - ₹20,000 crore Budget outlay signals fiscal commitment to indigenous SMR technology [S2]. - Opening to private/JV models (46 GW of the 100 GW target) is expected to crowd in private capital previously deterred by liability risk [S1][S6]. - Repurposing retiring fossil plants for SMRs saves on transmission infrastructure and land acquisition costs [S1].
Legal/Constitutional - SHANTI Act, 2025 repeals/consolidates the Atomic Energy Act, 1962 and CLND Act, 2010 — a rare full legislative overhaul of a Nehru-era statute [S6]. - Introduces operator-recourse rights (contractual) against suppliers, addressing the "unlimited liability" concern that kept US/foreign majors (e.g., under Convention on Supplementary Compensation) away [S6]. - Establishes the Nuclear Damage Claims Commission as a dedicated adjudicatory body [S6].
Scientific/Technological - Indigenous reactor designs (700 MWe PHWR, BSMR-200, SMR-55) reflect India's push for self-reliant reactor technology (Atmanirbhar Bharat in strategic sector) [S1]. - SMRs enable modular, factory-fabricated, faster-deployment nuclear technology suited for captive industrial and off-grid use [S1].
Environmental - Nuclear positioned as "reliable, low-carbon base-load" energy, complementing intermittent renewables in India's energy mix [S1]. - Directly tied to Net Zero by 2070 commitment (made at COP26, Glasgow) [S1].
Geopolitical/Strategic - Private-sector opening is partly aimed at enabling collaboration with foreign reactor vendors/technology partners, historically stalled by liability law [S6]. - Energy security angle — reduces dependence on fossil fuel imports for base-load power.
Administrative/Governance - A Task Force within DAE (members from DAE, AERB, NPCIL, NITI Aayog, Ministry of Law & Justice, MEA) was constituted to recommend amendments to the Atomic Energy Act, preceding the SHANTI Act [S3]. - Capacity addition split between NPCIL (54 GW) and other PSEs/states/private players (46 GW) raises coordination and regulatory-oversight challenges [S1].
6. Recent Developments (last 12-18 months)
- Feb 2025: Union Budget 2025-26 announces Nuclear Energy Mission with ₹20,000 crore outlay for SMRs [S2][S4].

8. Mains Relevance
- GS-III: Infrastructure — Energy; Science & Technology — indigenization of technology; Environment — climate change mitigation, Net Zero.
- GS-II: Government policies and interventions; statutory bodies (Nuclear Damage Claims Commission).
- Possible question stems: 1. "India aims to achieve 100 GW nuclear capacity by 2047. Discuss the strategy adopted and the legal/institutional reforms needed to enable private sector participation in this sector." (GS-III, 15 marks) 2. "Examine how the SHANTI Act, 2025 addresses the liability concerns that historically deterred foreign investment in India's nuclear power sector." (GS-II/III, 10 marks) 3. "Small Modular Reactors are being positioned as a game-changer for India's decarbonization strategy. Critically evaluate their potential and challenges." (GS-III, 15 marks)

10. Common Errors / Trap Areas
- Confusing Department of Atomic Energy (DAE) with the Ministry of Power as the nodal authority — DAE is correct [S1].
- Mixing up BSMR-200 (200 MWe) with SMR-55 (55 MWe) — different indigenous SMR designs, not the same reactor [S1].
- Assuming SHANTI Act merely amended the CLND Act, 2010 — it actually consolidated/repealed both the 1962 and 2010 Acts into a unified framework [S6].
- Confusing the 54 GW (NPCIL) and 46 GW (others) split — total is 100 GW by 2047, not additive beyond that [S1].
- Assuming all 100 GW comes from SMRs — SMRs are only one prong (brownfield); large PHWR/imported reactors at greenfield sites form the other, larger prong [S1].
