The Lift Line

A target announced in gigawatts is a slogan; a target with named financing routes is a policy.

Why This Editorial Matters for Your Exam

Nuclear questions in GS 3 now sit at the intersection of energy policy and project finance, and the SHANTI consultation gives an examiner a clean hook. This piece supplies the target, the funding gap, the three technology tracks and the international comparators in a form an answer can use directly.

GS Paper 3: Infrastructure: energy; achievements of Indians in science and technology, indigenisation of technology and developing new technology; conservation, environmental pollution and degradation.

Concept Meaning Why it is testable
PHWR Pressurised heavy-water reactor, the mainstay Indian civilian design The technology that will do most of the capacity addition in the near term
Small modular reactor (SMR) Reactors of typically 300 MW or less designed for factory build The category the Bharat Small Reactor tender is opening
HALEU High-assay low-enriched uranium, 5 to 20 per cent U-235 The fuel constraint that decides whether SMRs can be commissioned on time

Background and Context

The occasion. The SHANTI Act, 2025, short for Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India, was enacted in 2025, receiving the President’s assent on 20 December 2025, and repealed and replaced both the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010, putting nuclear promotion, regulation and liability into a single statute and opening generation to private and foreign participation for the first time. Against that background, the Department of Atomic Energy published the Draft SHANTI Rules, 2026 on 14 August 2026 and the public consultation on them closed on 4 September 2026. The rules, not the Act, are where the private-participation framework is actually being written.

The target and the gap. The Government of India has set a target of 100 gigawatts of nuclear capacity by 2047. The financing requirement is roughly 25 lakh crore rupees over two decades, well beyond what treasury allocations alone can supply.

The current position. India has 24 operable nuclear reactors, a proven pressurised heavy-water reactor line, the fast breeder reactor at Kalpakkam, and about 9 gigawatts of installed nuclear capacity built up over six decades under Nuclear Power Corporation of India (NPCIL) and its subsidiaries.

The international record on cost. Westinghouse filed for bankruptcy in 2017 after cost overruns on AP1000 projects in the United States. The United Kingdom’s Hinkley Point C project, at 3.2 gigawatts, has been under sustained delay and cost revision. Both projects illustrate what happens when private capital is asked to bear both technology and completion risk without a clear allocation.

The three technology tracks. First, PHWR capacity expansion using proven Indian designs. Second, Bharat Small Reactor, a 220 megawatt indigenous unit tendered for private financing and build with operation under NPCIL control, with 20,000 crore rupees allocated for five units by 2033. Third, large imported reactors under export credit agency backing.

The financing wrinkle. India’s sovereign green bond framework, drafted by the Ministry of Finance, currently excludes nuclear. HALEU, high-assay low-enriched uranium, is a specific fuel constraint for indigenous SMRs. The op-ed is co-authored by Ravi Madhavan (University of Pittsburgh), Tom Nguyen (formerly of Westinghouse) and K Ramanathan (TERI).

The Analysis

1. The Bharat Small Reactor tender crystallises the architecture problem. The tender proposes private financing and construction of 220 megawatt units to be operated under NPCIL control. Lenders financing large infrastructure require step-in rights, the ability to take over a project on borrower default. When the operator is a public monopoly, those rights are legally awkward. The SHANTI Rules are the moment to resolve this with a defined operator-lessor structure, or the tender will clear at a cost of capital that reflects the unresolved risk.

2. The three tracks are not substitutable, and treating them as one is the portfolio error. PHWR expansion is a proven technology with a domestic supply chain, its risk is scale and land, not technology. Indigenous SMRs carry first-of-a-kind risk with no reference plant, and their fuel supply is a HALEU-diplomacy problem. Large imported reactors have a geopolitical exposure on top of a technology exposure. A financing model built for one is inappropriate for the others.

3. The sovereign green bond exclusion is the low-hanging fruit. The Ministry of Finance’s green bond framework currently excludes nuclear despite the sector’s clear decarbonisation credentials. Amending the framework to include qualifying nuclear projects, with the standard safeguards, would open a defined corpus to a technology track that is currently financed only from the general budget.

4. The international precedents are cautionary, not exhaustive. Westinghouse and Hinkley Point are the two most cited failures, and they share a common pathology, unresolved risk allocation between technology, completion and financing. India’s advantage is that it has a proven PHWR line whose completion risk is well understood, so the PHWR track can be financed on infrastructure-project terms while the SMR track is financed on venture terms. Different tracks, different terms.

5. HALEU is the specific supply constraint the SMR track has not addressed. SMRs require enrichment to between 5 and 20 per cent U-235. The Indian civil enrichment programme is not currently at this scale, and the international HALEU market is thin. Supply diplomacy, with countries developing HALEU capacity, is the practical route, and it is a diplomatic rather than a domestic problem.

Data and Institutions Vault

Prelims-grade facts:

The target and the current position:

  • The Government of India has set a target of 100 gigawatts of nuclear capacity by 2047.
  • The estimated capital requirement is approximately 25 lakh crore rupees over two decades.
  • India has 24 operable civilian nuclear reactors and about 9 gigawatts of installed nuclear capacity.
  • The Nuclear Power Corporation of India Limited (NPCIL), under the Department of Atomic Energy, is the primary operator.
  • The Kalpakkam Fast Breeder Test Reactor and the Prototype Fast Breeder Reactor are located in Tamil Nadu.
  • Bhabha Atomic Research Centre (BARC) is at Trombay, Mumbai.

The SHANTI consultation and the tender:

  • SHANTI stands for Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India.
  • The Bharat Small Reactor is a 220 megawatt indigenous unit designed for private financing and build with NPCIL operation.
  • 20,000 crore rupees have been allocated for five SMR units by 2033.
  • India’s sovereign green bond framework currently excludes nuclear.

The international comparators and constraints:

  • Westinghouse filed for bankruptcy in 2017 after AP1000 cost overruns.
  • The UK’s Hinkley Point C project has a nameplate capacity of 3.2 gigawatts.
  • HALEU (high-assay low-enriched uranium) is uranium enriched between 5 and 20 per cent U-235.
  • The SHANTI Act, 2025 is now the primary Indian legislation on nuclear energy.
  • It repealed and replaced both the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010.
  • The SHANTI Bill was passed in Parliament in December 2025 and received the President’s assent on 20 December 2025.
  • Under the SHANTI Act the operator alone bears liability for nuclear damage, and the supplier’s right of recourse created by the 2010 Act is removed.
  • Operator liability is capped and graded by installed capacity rather than by the extent of damage.
  • For background: the Draft SHANTI Rules, 2026 were published on 14 August 2026 and the consultation on them closed on 4 September 2026.

⚠️ Watch the trap: A small modular reactor is defined by design and delivery model, factory build, modular assembly, typically 300 megawatts or less, not by the size of any specific unit. Referring to a specific SMR by its nameplate capacity as if that were the definition, or describing SMRs as “smaller nuclear plants”, is a common answer-writing error. The point of the SMR category is the factory model, not the megawatt count.

The Debate

FOR (nuclear scale is necessary): A 24x7 low-carbon baseload cannot be delivered by renewables alone at Indian summer demand peaks. Nuclear is the technology that provides that baseload, and the target of 100 gigawatts is aligned with the country’s 2070 net-zero commitment. The financing question is a solvable engineering problem, and the SHANTI consultation is the correct venue.

AGAINST (money and time better spent elsewhere): Nuclear is expensive, slow to build and unpopular. The same 25 lakh crore rupees would deliver more decarbonisation faster if directed to renewables plus storage, whose economics are still improving. Locking into a technology whose costs have not stabilised is a portfolio mistake.

Balanced verdict: Both are partly right. Renewables plus storage are the fastest decarbonisation route; nuclear provides the baseload that renewables cannot yet deliver at Indian scale. The productive answer is to publish a technology-track allocation with named financing routes, to resolve the ownership-control mismatch in the Bharat Small Reactor tender, and to amend the green bond framework. A portfolio approach beats a single-technology bet in either direction.

How to Think About This

When a target is set in physical units, gigawatts, kilometres, tonnes, ask two questions. What is the financing architecture, and what is the risk allocation between government, developer, lender and consumer. Announcements that leave those blank are announcements, not policies. Then ask whether the technologies inside the target carry the same risk profile. Where they do not, a single financing model is a portfolio failure in the making. The productive answer treats each track on its own terms and refuses the tidy communication of a single number.

Diagram-in-Words

Track 1: PHWR scale-up proven, domestic supply chain infrastructure-project finance Track 2: BSR / SMR 220 MW, no reference plant venture terms, HALEU risk Track 3: large imports export-credit backed geopolitical exposure SHANTI rules resolve architecture ownership-control, step-in, green bond, HALEU Target: 100 GW by 2047 from about 9 GW today roughly 25 lakh crore rupees
Three tracks, three risk profiles, one target. A single financing model that treats them as one is a portfolio failure; the SHANTI rules are where the three routes are meant to be separated by risk and reunited by target.

Takeaway Box

Lift line: A target announced in gigawatts is a slogan; a target with named financing routes is a policy.
