PARLIAMENT QUESTION: NUCLEAR ENERGY MISSION

1. At a Glance

• Nuclear Energy Mission (NEM): ₹20,000 crore Union Budget 2025–26 initiative for R&D, design and deployment of Small Modular Reactors (SMRs) under the Department of Atomic Energy (DAE) [1][2].
• Aims at operationalising ≥5 indigenously developed SMRs by 2033 and 100 GW of nuclear capacity by 2047 as part of India's energy transition [2].
• Signals a structural shift: SMRs (compact, factory-built, <300 MWe) replacing the legacy reliance on large PHWRs, with proposed private-sector entry via amendments to the Atomic Energy Act, 1962 and CLND Act, 2010 [2].
• UPSC relevance: cuts across GS-III (energy, S&T), GS-II (legislation), and environment (clean transition).

2. Why in the News

• 11 March 2026 PIB Parliament Q&A by DAE disclosed allocation break-up across BSMR-200, SMR-55 and HTGR under the Nuclear Energy Mission [1].
• Follows the Union Budget 2025–26 (1 Feb 2025) announcement by FM Nirmala Sitharaman creating the Mission with ₹20,000 cr outlay [2].

3. Background & Evolution

• India's civilian nuclear programme rooted in Atomic Energy Act, 1962; three-stage programme conceived by Homi J. Bhabha.
• Civil Liability for Nuclear Damage Act, 2010 enacted post Indo-US 123 Agreement (2008).
• Budget 2025–26 (1 Feb 2025) announced Nuclear Energy Mission + ₹20,000 cr R&D outlay for SMRs; targets 100 GW by 2047 and 5 SMRs by 2033 [2].
• Designs entrusted to BARC (constituent unit of DAE): BSMR-200, SMR-55, HTGR [1].

4. Core Static Facts

• Parent ministry/dept: Department of Atomic Energy (under PMO) [1].
• Implementing R&D body: Bhabha Atomic Research Centre (BARC) [1].
• Total outlay: ₹20,000 crore (Budget 2025–26) [1][2].
• Reactors under development [1]:
• BSMR-200: 220 MWe Bharat Small Modular Reactor; outlay ₹5,960 cr (lead unit cost ~₹5,700 cr) [1][3].
• SMR-55: 55 MWe SMR for remote/off-grid use [1][3].

• HTGR: up to 5 MWth High Temperature Gas Cooled Reactor for hydrogen generation [1].

• Lead-unit sites: Tarapur (Maharashtra) for BSMR-200 & SMR-55; Visakhapatnam (Andhra Pradesh) BARC site for HTGR [3].

• Construction timeline: 60–72 months from approval (BSMR) [3].
• Targets: ≥5 indigenous SMRs by 2033; 100 GW nuclear by 2047 [2].
• Legislative track: Amendments proposed to Atomic Energy Act, 1962 and CLND Act, 2010 to enable private participation [2].

5. Multi-Dimensional Analysis

Economic

• ₹20,000 cr seed funding for indigenous reactor design; aims at replacing imported large reactors with modular standardised builds [1].
• BSMR-200 designed for repurposing retiring coal/thermal plants — reuse of grid infrastructure, land, workforce [3].

Scientific / Technological

• SMRs: <300 MWe, factory-fabricated, passive safety, shorter gestation than 700-MWe PHWRs.
• HTGR enables non-electric applications: process heat + green/pink hydrogen production [1].

Environmental / Climate

• Supports Panchamrit & net-zero-2070 commitments; nuclear treated as clean baseload supplementing solar intermittency [2].

Legal / Governance

• Currently Atomic Energy Act bars private operators; amendments would unlock PPP and private capex [2].
• CLND Act's supplier-liability clause (Sec. 17(b)) historically deterred foreign suppliers; reform critical for SMR ecosystem [2].

Strategic

• Reduces uranium import dependence over long term; aligns with IAEA cooperation and Indo-US/Indo-French civil nuclear ties.

6. Recent Developments (last 12-18 months)

• 1 Feb 2025: Budget 2025-26 announces Nuclear Energy Mission, ₹20,000 cr [2].
• 2025: BARC commences design of BSMR-200, SMR-55, HTGR; sites identified at Tarapur and Visakhapatnam [3].
• 11 Mar 2026: PIB Parliament Q&A discloses outlay split — BSMR-200: ₹5,960 cr [1].
• Government signalled amendments to Atomic Energy Act and CLND Act in Budget speech [2].

7. Prelims Hooks

• Nuclear Energy Mission outlay: ₹20,000 crore (Budget 2025–26) [1][2].
• BSMR-200 capacity: 220 MWe; outlay ₹5,960 crore [1].
• SMR-55 capacity: 55 MWe, for remote/off-grid sites [1][3].
• HTGR: up to 5 MWth, purpose — hydrogen generation [1].
• Implementing R&D unit: BARC, constituent of DAE (under PMO, not MNRE) [1].
• Sites: Tarapur (Maharashtra) for BSMR-200/SMR-55; Visakhapatnam (AP) for HTGR [3].
• Target: 5 SMRs operational by 2033; 100 GW nuclear by 2047 [2].
• Construction time for BSMR: 60–72 months [3].
• Acts proposed for amendment: Atomic Energy Act, 1962 & CLND Act, 2010 [2].
• SMR definition: typically <300 MWe factory-built modular reactor.
• Announcement made by FM Nirmala Sitharaman in Budget speech, 1 Feb 2025 [2].
• DAE Minister: Dr. Jitendra Singh (MoS, PMO/DAE) [2].

8. Mains Relevance

• GS-III: Energy security; Science & Technology — indigenisation; Infrastructure.
• GS-II: Government policies, statutes (Atomic Energy Act, CLND Act).
• Likely question stems:
• "Examine the role of Small Modular Reactors in India's net-zero pathway. How does the Nuclear Energy Mission reconfigure the country's civilian nuclear architecture?"
• "Critically analyse the legislative reforms needed to enable private participation in India's nuclear sector."
• "Discuss the techno-economic feasibility of repurposing retiring thermal plants with BSMR-200 reactors."

9. Related Topics to Study Next

• Three-stage Nuclear Programme — context for SMR positioning.
• CLND Act, 2010 & Section 17(b) — supplier liability debate.
• National Green Hydrogen Mission (2023) — links to HTGR.
• Panchamrit / Net-Zero 2070 — climate framework.
• IAEA & NSG — international architecture.
• Bharat Small Reactor vs Bharat SMR — terminology trap.
• Kudankulam, Kakrapar (KAPP-3/4 700 MWe PHWR) — comparison.
• Indo-US 123 Agreement (2008) — historical foundation.

10. Common Errors / Trap Areas

• DAE ≠ MNRE: nuclear power is under DAE/PMO, not Ministry of New & Renewable Energy.
• BSMR-200 = 220 MWe, not 200 MWe (the "200" is a class label, not exact capacity) [1].
• HTGR rating is MWth (thermal), not MWe; primary purpose is hydrogen, not grid power [1].
• Confusing Bharat Small Reactor (BSR-220, a PHWR variant) with Bharat Small Modular Reactor (BSMR-200) — distinct programmes.
• Target year confusion: 5 SMRs by 2033, 100 GW by 2047 — don't swap.
• CLND Act year is 2010, Atomic Energy Act is 1962.
