PARLIAMENT QUESTION: DEPLOYMENT OF SMALL MODULAR REACTORS (SMRs)

1. At a Glance

• Small Modular Reactors (SMRs) are advanced nuclear reactors (typically 16–300 MWe) with factory-fabricated modular components, suited for remote areas, captive industrial use, and replacing retiring fossil plants [S2].
• India's Nuclear Energy Mission (Union Budget 2025–26) provides ₹20,000 crore for R&D and deployment of indigenous SMRs; targets at least 5 operational indigenous SMRs by 2033 and 100 GW nuclear capacity by 2047 [S1][S2].
• Three indigenous SMR designs are under development: BSMR-200 (220 MWe), SMR-55 (55 MWe), and a 5 MWth high-temperature gas-cooled reactor for hydrogen generation [S1].

2. Why in the News

• 12 March 2026: Department of Atomic Energy (DAE) replied to a Parliament Question detailing progress on indigenous SMRs and the ₹20,000 crore budgetary provision under the Nuclear Energy Mission [S1].
• BSMR-200 received in-principle approval; Atomic Energy Commission (AEC) has cleared the administrative & financial sanction proposal for Cabinet submission [S1].

3. Background & Evolution

• 2015 onwards: Global IAEA classification of reactors <300 MWe as SMRs gains traction.
• Feb 2025: PM Modi's Union Budget 2025–26 announces the Nuclear Energy Mission with ₹20,000 crore for SMR R&D [S2].
• 2025: Draft SHANTI Bill, 2025 (Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India) — proposed framework to enable private participation [S2].
• March 2026: DAE confirms lead units of BSMR-200 and SMR-55 to be sited at Tarapur Atomic Power Station (Maharashtra) [S1].

4. Core Static Facts

• Nodal body: Department of Atomic Energy (DAE), under PMO [S1].
• Designers: Bhabha Atomic Research Centre (BARC) + Nuclear Power Corporation of India Ltd (NPCIL) [S1].
• Indigenous SMR portfolio:
• BSMR-200: 220 MWe Pressurised Water-type; lead unit cost ₹5,700 crore; construction 60–72 months from sanction [S1].
• SMR-55: 55 MWe [S1].
• HTGR: up to 5 MWth, high-temperature gas-cooled, for hydrogen production [S1].
• Budget: ₹20,000 crore (Nuclear Energy Mission, 2025–26) [S1][S2].
• 2047 Target: 100 GW nuclear capacity; NPCIL share = 54 GW via PHWRs + LWRs [S2].
• Use-cases: captive power for aluminium/steel; repurposing retiring thermal plants; off-grid/remote sites [S1].

5. Multi-Dimensional Analysis

Economic - ₹5,700 crore unit cost for BSMR-200 — lower per-unit capex than large LWRs; suitable for industrial captive use cutting industrial decarbonisation costs [S1]. - Repurposing retiring coal plants leverages existing grid + cooling water infrastructure → stranded-asset risk mitigation [S1].

Environmental / Climate - SMRs central to India's Panchamrit (COP-26) and Net-Zero by 2070 trajectory; nuclear is low-carbon firm power complementing variable RE [S2]. - HTGR enables green hydrogen via thermochemical/electrolytic routes — feeds National Green Hydrogen Mission [S1].

Scientific / Technological - Modular factory fabrication reduces construction risk vs. conventional 700 MWe PHWR builds [S1]. - HTGR demonstrates high-temperature process heat capability — first Indian foray beyond electricity generation in commercial-track reactors [S1].

Legal / Constitutional - Currently constrained by Atomic Energy Act, 1962 (Sec. 3) and Civil Liability for Nuclear Damage Act, 2010, which limit private sector ownership; proposed SHANTI Bill, 2025 aims to amend the framework [S2]. - Nuclear energy is a Union List subject (List I, Entry 6: atomic energy and mineral resources necessary for its production).

Geopolitical / Strategic - 100 GW by 2047 reduces fossil import dependence; aligns with IAEA "Atoms4NetZero" initiative [S2].

6. Recent Developments (last 12-18 months)

• 1 Feb 2025: Nuclear Energy Mission announced in Union Budget 2025–26 with ₹20,000 crore outlay [S2].
• 2025: SHANTI Bill, 2025 drafted to enable private/PPP participation in nuclear sector [S2].
• 12 Mar 2026: DAE Parliament reply — BSMR-200 in-principle approval received; AEC clears proposal for administrative & financial sanction; lead site Tarapur [S1].

7. Prelims Hooks

• Nuclear Energy Mission budget outlay: ₹20,000 crore (Union Budget 2025–26) [S1].
• Target: ≥5 indigenous SMRs operational by 2033; 100 GW nuclear by 2047 [S2].
• IAEA defines SMRs as reactors with capacity up to 300 MWe; Indian roadmap cites 16–300 MW range [S2].
• BSMR-200 capacity: 220 MWe (note: name "200" but rated 220 MWe) [S1].
• SMR-55: 55 MWe [S1].
• HTGR: up to 5 MWth, purpose = hydrogen generation [S1].
• Lead BSMR-200 unit cost: ₹5,700 crore; build time 60–72 months post-sanction [S1].
• Lead site for BSMR-200 and SMR-55: Tarapur Atomic Power Station, Maharashtra [S1].
• Joint developers: BARC + NPCIL [S1].
• NPCIL's 2047 share within 100 GW target: 54 GW via indigenous PHWRs + foreign-cooperation LWRs [S2].
• Atomic Energy Commission (AEC) — body that cleared the administrative & financial sanction proposal [S1].
• Nuclear energy is in Union List, Entry 6 of the Seventh Schedule.

8. Mains Relevance

• GS-III: Science & Technology (indigenisation; nuclear technology); Energy security; Infrastructure-Energy; Environment (climate change mitigation).
• GS-II: Government policies and interventions; statutes (Atomic Energy Act / SHANTI Bill).
• Probable question stems: 1. "Small Modular Reactors offer a pragmatic pathway to India's twin goals of energy security and net-zero. Examine the technological, legal and financial bottlenecks in their large-scale deployment." 2. "Discuss the significance of the Nuclear Energy Mission (2025) in the context of India's commitment to achieve 100 GW of nuclear capacity by 2047." 3. "Critically evaluate the role of Small Modular Reactors in decarbonising hard-to-abate industrial sectors and replacing retiring thermal power plants."

10. Common Errors / Trap Areas

• BSMR-200 is 220 MWe, not 200 MWe — the "200" in the name is a branding label, not the rating [S1].
• HTGR output is 5 MWth (thermal), not MWe — designed for hydrogen, not electricity [S1].
• Implementing department is DAE under PMO, not Ministry of Power or MNRE.
• Lead SMR site is Tarapur (Maharashtra), not Kudankulam or Kalpakkam [S1].
• Nuclear Energy Mission's ₹20,000 crore is for SMR R&D + deployment specifically, not the full nuclear capex.
• SMR upper bound per IAEA is 300 MWe, not 700 MWe (which is India's indigenous PHWR class).
