PARLIAMENT QUESTION: NUCLEAR POWER GENERATION

1. At a Glance

• Nuclear power is India's fifth-largest electricity source, operated centrally under the Department of Atomic Energy (DAE) via PSUs NPCIL, BHAVINI and JV ASHVINI (NPCIL+NTPC) [S1][S2].
• Generation rose from 47,971 MU (2023-24) → 56,681 MU (2024-25) — the highest ever in NPCIL's history, avoiding ~49 MT CO₂ [S1][S2].
• Government targets 100 GW nuclear capacity by 2047 under the Nuclear Energy Mission (Budget 2025-26) — relevant to GS-III (Energy Security, Science & Tech) [S3].

2. Why in the News

• 04 Feb 2026 Lok Sabha reply by DAE on nuclear generation, project status (Mahi Banswara, Kaiga 5&6), and the 500 MWe PFBR at Kalpakkam under commissioning by BHAVINI [S1].
• Two-year capacity addition of 2,100 MW disclosed; FBR 1&2 (2×500 MWe) at Kalpakkam given pre-project approval [S1].

3. Background & Evolution

• Atomic Energy Act, 1962 governs the sector; DAE established 1954 under direct charge of PM [S3].
• Three-stage nuclear programme (Bhabha): Stage-I PHWRs → Stage-II FBRs (thorium breeding) → Stage-III Th-U233 reactors [S2].
• 123 Agreement (2008) with USA + NSG waiver opened civil nuclear cooperation.
• Budget 2025-26: ₹20,000 cr Nuclear Energy Mission for SMR R&D; 5 indigenous SMRs to be operational by 2033 [S3].

4. Core Static Facts

• Implementing bodies: NPCIL (commercial PHWRs/LWRs), BHAVINI (FBRs), ASHVINI (NPCIL-NTPC JV for Mahi Banswara) [S1].
• Current installed nuclear capacity: 8,880 MW / 25 reactors [S2].
• Under construction: 13,100 MW [S2].
• Generation FY24-25: 56,681 MU [S1].
• Capacity added in last 2 years: 2,100 MW [S1].
• Target 2031-32: 22.38 GW; Target 2047: 100 GW [S2][S3].
• PFBR Kalpakkam: 500 MWe, sodium-cooled, by BHAVINI [S1].
• BSMR-200: 220 MWe Bharat SMR, PWR-based, uses Slightly Enriched Uranium (SEU); lead unit at Tarapur, Maharashtra [S3].
• Enabling laws to be amended: Atomic Energy Act 1962 & Civil Liability for Nuclear Damage Act 2010 (for private participation) [S3].

5. Multi-Dimensional Analysis

Economic - Capex-heavy but low marginal cost; supports base-load. ₹20,000 cr SMR outlay catalyses domestic ecosystem [S3]. - Mahi Banswara JV model brings PSU NTPC capital into atomic sector [S1].

Environmental - 49 MT CO₂ avoided in FY24-25 — pivotal for net-zero by 2070 pledge [S2]. - Closed fuel cycle (Stage-II FBR) reduces high-level waste volume and enables thorium use [S1].

Scientific / Technological - PFBR first criticality awaited; on success, twin FBR 1&2 (2×500 MWe) financial sanction follows [S1]. - DAE pursuing BSMR-200, SMR-55, 5 MWth HTGCR (hydrogen production) [S3].

Legal / Constitutional - Entry 6, Union List (Atomic Energy); Atomic Energy Act 1962 reserves nuclear material to Centre [S3]. - Amendment to CLND Act 2010 required to ease supplier-liability concerns blocking foreign reactor deals [S3].

Strategic - Energy security amid fossil-fuel imports; SMRs allow deployment at retired thermal sites & remote areas [S3].

6. Recent Developments (12-18 months)

• Feb 2025: Union Budget announces Nuclear Energy Mission; ₹20,000 cr for SMRs; 100 GW by 2047 target codified [S3].
• 2024-25: RAPP-7 (Rawatbhata, 700 MWe PHWR) synchronised to Northern Grid [S4].
• Feb 2026: DAE Lok Sabha reply confirms Kaiga 5&6 pre-project near completion; PFBR commissioning [S1].
• DAE pushing legislative amendments to Atomic Energy Act and CLND Act for private/foreign entry [S3].

7. Prelims Hooks

• Nuclear generation 2024-25: 56,681 MU [S1].
• Current installed nuclear capacity: 8,880 MW across 25 reactors [S2].
• Target by 2047: 100 GW under Nuclear Energy Mission [S3].
• Target by 2031-32: 22.38 GW [S2].
• ASHVINI = NPCIL + NTPC JV; executes Mahi Banswara (Rajasthan) units 1-4 [S1].
• BHAVINI commissioning 500 MWe PFBR at Kalpakkam (TN) [S1].
• Budget 2025-26 outlay for SMR R&D: ₹20,000 crore [S3].
• 5 indigenous SMRs operational by 2033 [S3].
• BSMR-200 lead unit site: Tarapur, Maharashtra; fuel: Slightly Enriched Uranium [S3].
• Variants under DAE: BSMR-200, SMR-55, HTGCR (5 MWth) for hydrogen [S3].
• Capacity added in last 2 years: 2,100 MW [S1].
• Atomic Energy is Entry 6, Union List; Act of 1962 [S3].
• CO₂ avoided in FY24-25: ~49 million tonnes [S2].
• Kaiga 5 & 6 — pre-project activities nearing completion (PHWR 700 MWe each) [S1].
• FBR 1&2: 2 × 500 MWe at Kalpakkam, pre-project approval granted [S1].

8. Mains Relevance

• GS-III — Energy security; Infrastructure; Science & Tech (indigenous reactor development).
• GS-II — Government policies (Budget mission), India-US/France civil nuclear ties.
• Likely stems: 1. "Discuss the role of nuclear power in India's net-zero pathway, in light of the Nuclear Energy Mission 2025-26." (250 words) 2. "Examine the legal and institutional reforms required to enable private participation in India's nuclear sector." 3. "Critically evaluate the progress of Stage-II of Bhabha's three-stage nuclear programme with reference to the PFBR at Kalpakkam."

9. Related Topics to Study Next

• Three-Stage Nuclear Programme — conceptual backbone of FBR/thorium policy.
• CLND Act 2010 & 123 Agreement — supplier-liability impasse on foreign reactor imports.
• NSG / IAEA Safeguards — India's place in non-proliferation architecture.
• Net-Zero 2070 & Panchamrit — nuclear's share in clean-energy mix.
• Thorium reserves (Kerala, Odisha sands) — links Stage-III rationale.
• NTPC and renewable mix — JV (ASHVINI) signals PSU diversification.
• Small Modular Reactors globally (IAEA classification) — comparative tech.
• Uranium supply: UCIL Jaduguda, foreign agreements (Kazakhstan, Canada, Australia).

10. Common Errors / Trap Areas

• NPCIL vs BHAVINI: NPCIL runs PHWRs/LWRs; BHAVINI is exclusively for Fast Breeder Reactors [S1].
• ASHVINI ≠ government scheme; it is a NPCIL-NTPC Joint Venture company [S1].
• PFBR is 500 MWe (not MWth) and located at Kalpakkam, TN (not Tarapur) [S1].
• "100 GW by 2047" is a target, not current capacity (8.88 GW today) [S2][S3].
• Nuclear is under Union List Entry 6, not Concurrent — states cannot legislate.
• BSMR fuel = Slightly Enriched Uranium, not natural uranium (unlike PHWRs) [S3].
