Nuclear Energy Technology in India

1. At a Glance

• India is executing its most ambitious nuclear expansion since 1962 — a 100 GWe installed nuclear capacity target by 2047, up from ~8 GWe today, tied to the Net Zero by 2070 pledge [1].
• The Nuclear Energy Mission (NEM), announced in Budget 2025-26 with a ₹20,000 crore outlay, seeks to open the sector to private capital for the first time since nationalisation [2][3].
• A new law — the SHANTI Act, 2025 — has been passed to amend the foundational Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage (CLND) Act, 2010, enabling private/state-sector entry [4][5].
• High-yield UPSC topic: intersects Science & Tech (GS-III), energy security, federalism, and legislative amendments (GS-II).

2. Why in the News

• Union Budget 2025-26 announced the Nuclear Energy Mission for Viksit Bharat with ₹20,000 crore for Small Modular Reactor (SMR) R&D [2][3].
• Parliament enacted the SHANTI Bill/Act, 2025 (Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India) to amend the 1962 and 2010 Acts and permit private participation [4].
• NPCIL floated a Request for Proposals inviting Indian industry to set up 220 MW Bharat Small Reactors (BSR) for captive, hard-to-abate industrial use [1].
• Bharat Small Modular Reactor (BSMR-200) — a 200 MWe design jointly developed by BARC and NPCIL — is in advanced stages of administrative/financial sanction under NEM funding [1].

3. Background & Evolution

• India's nuclear programme originated under Dr. Homi J. Bhabha, credited as its architect; the government invokes "Bhabha's pledge" in current Nuclear Mission messaging [3].
• Atomic Energy Act, 1962 — the foundational statute — nationalised nuclear power generation under the Central Government/DAE.
• Amendments in 1986, 1987, and 2015 progressively widened participation to government companies and joint ventures (still excluding private/foreign private players) [4].
• Civil Liability for Nuclear Damage (CLND) Act, 2010 introduced a no-fault liability regime for compensating nuclear-incident victims, long cited as a deterrent to foreign/private investment [4].
• 2025: Budget announcement of NEM → SHANTI Act, 2025 enacted to amend both 1962 and 2010 Acts, opening the door to private and state-sector participation [2][4].

5. Multi-Dimensional Analysis

Economic

• ₹20,000 crore Budget allocation signals a shift from pure sovereign funding to a public-private capital-mobilisation model for SMRs [2].
• Captive BSRs target energy-intensive, "hard-to-abate" industries (steel, cement, aluminium) seeking decarbonised captive power [1].

Environmental

• Nuclear expansion is explicitly positioned as a low-carbon baseload complement to renewables, in service of the Net Zero by 2070 commitment [1][3].

Legal / Constitutional

• SHANTI Act, 2025 amends two Central Acts (1962, 2010) — a significant legislative departure from the state-monopoly model that has held since Independence [4].
• CLND Act's no-fault liability regime remains a live governance/legal tension point as private players enter, since liability allocation between operator and supplier was historically contentious [4].

Scientific / Technological

• Twin indigenous SMR tracks: BSMR-200 (general power) and HTGCR (hydrogen production) show diversification beyond electricity generation into green hydrogen [1][3].
• Reliance on indigenous PHWR technology (leveraging India's natural uranium/heavy-water expertise, non-NPT-compliant fuel cycle) alongside foreign-cooperation LWRs reflects India's dual-track strategic-autonomy approach [3].

Administrative / Governance

• Implementation split flagged explicitly: NPCIL to deliver 54 GW of the 100 GW target, remainder expected from private/state entrants and SMR deployment [3].
• Sector opening requires parallel regulatory capacity-building (safety oversight remains with the statutory nuclear regulator even as ownership diversifies).

6. Recent Developments (last 12-18 months)

• Union Budget 2025-26: Nuclear Energy Mission for Viksit Bharat announced with ₹20,000 crore allocation [2][3].
• 2025: SHANTI Bill introduced and enacted, amending Atomic Energy Act 1962 and CLND Act 2010 [4].
• NPCIL RFP issued inviting Indian industry participation for 220 MW Bharat Small Reactors for captive use [1].
• BSMR-200 R&D funded under NEM, reported to be in advanced stage of administrative/financial sanction [1].
• Multiple Parliament Questions (Lok Sabha/Rajya Sabha) taken up on SMR development, deployment timelines, and Nuclear Energy Mission progress, indicating active legislative scrutiny [1][2].

8. Mains Relevance

• GS-III: Science and Technology — indigenous technology development; Infrastructure — Energy.
• GS-II: Government policies and interventions; statutes and legislative amendments (Atomic Energy Act, CLND Act amendments).
• Possible question stems: 1. "Discuss the significance of the Nuclear Energy Mission and the SHANTI Act, 2025 in India's clean energy transition. What legal and liability challenges must be addressed to attract private investment in nuclear power?" 2. "Small Modular Reactors are being positioned as India's next frontier in nuclear technology. Examine their strategic and economic rationale compared to large conventional reactors." 3. "India's Civil Liability for Nuclear Damage Act, 2010 has been both a safeguard and a deterrent. Critically evaluate its role in shaping India's nuclear energy trajectory."

10. Common Errors / Trap Areas

• Confusing Bharat Small Reactor (BSR — 220 MW PHWR, captive use) with Bharat Small Modular Reactor (BSMR-200 — 200 MWe, grid/general use); they are distinct designs.
• Assuming private companies can now own nuclear plants outright — the SHANTI Act enables participation, not full private ownership; DAE/regulatory oversight continues.
• Mixing up the Nuclear Energy Mission (2025, domestic capacity expansion) with the older India-US 123 Agreement (2008, international cooperation) — different scope and era.
• Misattributing the nodal ministry — it is DAE (directly under PMO), not the Ministry of Power or MNRE.
• Forgetting that the 100 GWe target is for 2047, while the SMR-specific target is 2033 — different deadlines for different sub-goals.
