PARLIAMENT QUESTION: NUCLEAR ENERGY PROJECTS

1. At a Glance

• Department of Atomic Energy (DAE) statement to Parliament (12 Mar 2026) on India's nuclear power footprint, pipeline reactors and the Nuclear Energy Mission (NEM) target of 100 GW by 2047 [1][2].
• Relevant for GS-III (Energy/Infrastructure) and GS-II (Government policies); ties together net-zero-2070, energy security, and indigenous PHWR/SMR technology [2][3].

2. Why in the News

• 12 Mar 2026 Lok Sabha reply by DAE updating reactor numbers, pipeline (18 reactors / 13,600 MW), and three new fleet sites (KAPP-5&6, RAPP-9&10, NAPP-3&4) planned by 2035 [1].
• Follows the Union Budget 2025-26 launch of the Nuclear Energy Mission with ₹20,000 crore outlay for indigenous Small Modular Reactors (SMRs); ≥5 SMRs to be operational by 2033 [2][3].

3. Background & Evolution

• India's three-stage nuclear programme conceived by Homi Bhabha (1950s): Stage-1 PHWRs (natural U) → Stage-2 Fast Breeders (Pu-U) → Stage-3 Thorium (U-233) [2].
• Atomic Energy Act, 1962 & Atomic Energy Commission (1948) govern the sector; NPCIL (1987) operates commercial reactors; BHAVINI (2003) implements fast-breeder programme [1].
• Indo-US Civil Nuclear Deal (2008) + IAEA safeguards + NSG waiver opened foreign fuel/tech access; CLNDA, 2010 governs liability [2].
• 2024–25 reform push: fleet-mode 10×700 MW PHWRs sanctioned; Bharat Small Reactor (BSR) & BSMR-200 concept; Budget 2025-26 announces NEM [2][3].

4. Core Static Facts

• Installed capacity: 8,780 MW across 24 reactors (excludes RAPS-1, 100 MW) [1].
• Under implementation: 18 reactors / 13,600 MW — 8 under construction (incl. PFBR-500 MW) + 10 in pre-project; completion progressively by 2031-32 [1].
• Post-completion target capacity: 22,380 MW [3].
• New fleet (by 2035): KAPP-5&6, RAPP-9&10, NAPP-3&4 — each 2×700 MW indigenous PHWR [1].
• NEM goal: 100 GW nuclear by 2047; aligns with Net-Zero 2070 [2].
• PFBR: 500 MWe at Kalpakkam, Tamil Nadu, under BHAVINI commissioning [1].
• SMR designs (BARC-led): BSMR-200 (200 MWe), SMR-55 (55 MWe), HTGCR up to 5 MWth [2].
• Budget outlay (NEM, FY 25-26): ₹20,000 crore for SMR R&D; ≥5 indigenous SMRs by 2033 [2].
• Nodal Ministry: Department of Atomic Energy under Prime Minister's Office (not MoP/MNRE) [1].

5. Multi-Dimensional Analysis

• Economic — Capital-intensive baseload; fleet-mode 10×700 MW PHWRs cut per-MW cost; brownfield SMRs can repurpose retiring coal plants [2].
• Environmental — Low-carbon baseload; key to 500 GW non-fossil-2030 INDC and 2070 net-zero; replaces coal in energy-intensive industry [2].
• Scientific/Technological — Two-pronged: 700 MWe PHWR at greenfield + BSMR-200/SMR-55 for brownfield, off-grid, captive industrial use [2].
• Strategic — Reduces oil/coal import dependence; PFBR commissioning marks Stage-2 transition unlocking thorium pathway [1][2].
• Legal/Governance — Atomic Energy Act 1962 reserves nuclear power to Centre (Union List Entry 6, 7th Schedule); CLNDA 2010 caps operator liability; amendments to allow private participation are under consideration as per NEM roadmap [2].

6. Recent Developments (last 12-18 months)

• Feb 2025: Union Budget 2025-26 announces Nuclear Energy Mission with ₹20,000 cr SMR outlay [2].
• 2025: BHAVINI begins commissioning of PFBR-500 MWe at Kalpakkam [1].
• Mar 2026: DAE Parliament reply confirming 8,780 MW operational, 13,600 MW under implementation, plus KAPP-5&6/RAPP-9&10/NAPP-3&4 sanctioned [1].

7. Prelims Hooks

• Current installed nuclear capacity: 8,780 MW / 24 reactors (excluding RAPS-1) [1].
• RAPS-1 (100 MW) is excluded — under extended shutdown [1].
• 18 reactors / 13,600 MW under implementation, completion by 2031-32 [1].
• PFBR: 500 MWe, sodium-cooled fast breeder, located at Kalpakkam under BHAVINI [1].
• NEM target: 100 GW by 2047; 5 indigenous SMRs by 2033 [2].
• KAPP, RAPP, NAPP units to be added — each 2×700 MW indigenous PHWR [1].
• BSMR-200 = 200 MWe; SMR-55 = 55 MWe; designs by BARC [2].
• ₹20,000 crore SMR budget under NEM (Budget 2025-26) [2].
• Implementing agency for commercial reactors: NPCIL; for fast breeders: BHAVINI [1].
• Atomic Energy is Entry 6, Union List; governed by Atomic Energy Act, 1962 [2].
• Post-completion projected capacity: 22,380 MW [3].

8. Mains Relevance

• GS-III — Energy security; Infrastructure; Indigenisation of technology.
• GS-II — Government policies (NEM); Centre-State (siting, land).
• Plausible stems:
• "Discuss the role of Small Modular Reactors in achieving India's Nuclear Energy Mission target of 100 GW by 2047."
• "Critically examine the legal and institutional reforms needed to enable private participation in India's nuclear power sector."
• "Assess the significance of the commissioning of the Prototype Fast Breeder Reactor for India's three-stage nuclear programme."

9. Related Topics to Study Next

• Three-stage nuclear programme — directly contextualises PFBR/thorium roadmap.
• CLNDA 2010 — liability bottleneck for foreign reactor vendors.
• Indo-US Civil Nuclear Deal & NSG waiver — fuel-supply backbone.
• Net-Zero 2070 & INDCs — demand-side rationale.
• IAEA Safeguards & Additional Protocol — international compliance framework.
• Thorium reserves (Kerala/Odisha beach sands) — Stage-3 feedstock.
• Uranium Corporation of India Ltd (UCIL) — fuel supply chain.
• Renewable Energy Mission / PM-Surya Ghar — comparative clean-energy push.

10. Common Errors / Trap Areas

• Confusing nodal ministry: DAE reports to PMO, NOT MNRE or Ministry of Power.
• RAPS-1 (100 MW) is excluded from the 8,780 MW figure — easy misread.
• PFBR is under BHAVINI, not NPCIL — both are DAE PSUs but distinct.
• NEM target = 100 GW by 2047, not by 2030 or 2070 (2070 is net-zero year).
• BSMR-200 (200 MWe) ≠ SMR-55 (55 MWe) — two separate indigenous SMR designs.
