Baseload ethics and the SHANTI Act
THE NUCLEAR FLOOR · 2026 · PART 7 OF 12 As of 2026, nuclear power is the invisible floor of India's grid. Coal still produces about 75% of actual electricity, but the SHANTI Act has quietly redrawn how the next 91 GW of nuclear capacity will be built — and who can build it. |

01 · BASELOAD VS INTERMITTENCY — WHY NUCLEAR IS BACK
Nuclear is not a marginal contributor. It is the precondition that lets the renewable share grow.
Solar and wind do remarkable things to a grid in the daytime. They do nothing for it at sunset. India’s 2026 transition story has been dominated by the 500 GW non-fossil headline, but the engineering reality is that intermittent generation needs something to lean against — a steady, dispatchable, 24×7 source that maintains the minimum frequency requirements of a stable grid.
That something has historically been coal — about three-quarters of actual generation in 2026. The decarbonisation question is not whether coal goes; it is what replaces it. The two candidates are large-scale storage (covered in Part 09’s hybrid-mix economics) and clean baseload. Nuclear is the only mature, dispatchable, low-carbon, fuel-secure option in the second category.
Reframed in those terms, nuclear is not competing with renewables. It is the precondition that lets the renewable share keep growing without the system becoming brittle.
02 · THE SHANTI ACT — FROM EXECUTIVE AERB TO STATUTORY AERB
The most important institutional change in India’s nuclear scene is legislative, not technical.
The SHANTI Act (Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India) is the single most consequential reform since India first developed civilian nuclear capacity. Three things it does that no earlier legislation did:
▸ Statutory AERB. Grants legislative status to the Atomic Energy Regulatory Board, upgrading it from an executive body subordinate to the DAE to an independent, legislatively-empowered regulator.
▸ Private entry. Opens the civil nuclear sector — for the first time — to limited private sector participation, particularly in Small Modular Reactors and certain operational segments.
▸ Graded liability. Establishes a graded liability framework and a Nuclear Liability Fund for victim compensation, overlaying and partially replacing the CLNDA 2010 regime.
CRITIQUE · PRE-SHANTI AERB STRUCTURAL CONFLICT OF INTEREST The CAG Performance Audit of the Atomic Energy Regulatory Board (Report No. 9 of 2012) is the canonical pre-SHANTI critique. Its findings are definitive: "the legal status of AERB continued to be that of an authority subordinate to the central government … more of a subordinate authority with powers delegated to it than of a statutory body with independent powers." On the conflict-of-interest core: "the chairman, AEC and the secretary, DAE are one and the same … negates the very essence of institutional separation of regulatory and non-regulatory functions." AERB had never prepared the nuclear-and-radiation-safety policy it was mandated to prepare in 1983. The SHANTI Act's effectiveness depends entirely on whether it cures this structural defect or carries it forward. The answer will be visible in the first five years of AERB decisions made under the new regime. Sources: CAG Report No. 9 of 2012; Down to Earth; IEEE Spectrum — Indian Nuclear Reform Falls Short. |

The structural significance: nuclear regulation moves from being part of the executive arm of the nuclear establishment to being a legislative check on it. That changes who can be held to account, and how.
03 · PRIVATE PARTICIPATION AND SOVEREIGNTY TRADE-OFFS
Opening nuclear to private capital creates new questions about who profits, who controls, who is liable.
The trade-off the SHANTI Act has tried to thread is the sharpest one in the sector. Indian nuclear has historically been a state monopoly — for reasons of safety, fuel-cycle security and weapons-programme adjacency. Opening it to private capital lowers cost and accelerates deployment, but creates ethical questions the existing framework was not designed to answer.
The Act manages this tension by allowing private participation in new technologies (SMRs in particular) and certain operational segments, while retaining strict state control over sensitive nuclear fuel-cycle activities and security-relevant infrastructure. Private and foreign equity is capped at 49%.
PIPELINE · NAMED PRIVATE PLAYERS POST-SHANTI Six named bidders have submitted Expressions of Interest for the NPCIL Bharat Small Reactor (BSR) tender (RFP issued 31 December 2024; deadline extended to 31 March 2026): Adani Power, JSW Energy, Jindal Steel & Power, Reliance Industries, Tata Power, and Hindalco Industries. The most concrete vehicle in flight is Adani Power's, which has incorporated two nuclear-focused entities: Rawatbhata-Raj Atomic Energy Ltd and Coastal-Maha Atomic Energy Ltd — the first dedicated private-sector corporate vehicles for nuclear development after SHANTI. Six bidders for a single tender is a credible expression of market interest. Whether any translates into operational capacity within the 2033 target window is the test that will matter.

The political-economy bet is that capital flows accelerate deployment while strategic control remains with the state. Whether that bet holds will be visible by 2028 — the first cohort of private-participation SMR licences should be live by then.
04 · CAPACITY ROADMAP — 8.78 GW → 22.38 GW → 100 GW
That trajectory is not unrealistic on paper. It is unprecedented in execution.
The numbers: current installed nuclear capacity 8.78 GW. The 2031–32 target is 22.38 GW — a 2.5× scale-up in six years. The 2047 target is 100 GW — an 11× scale-up from today.
India has commissioned roughly 6 GW of nuclear capacity in the last twenty years. The next decade must deliver approximately 14 GW of net new capacity, and the two decades after that must deliver another 78 GW. Nothing in India’s nuclear construction history makes this easy.
The roadmap requires three things simultaneously: large conventional reactor construction (Kudankulam-style PHWR and LWR units), an early commercial-scale fast breeder programme (Stage 2 of the Three-Stage Programme, covered in Part 08), and a parallel SMR build-out for industrial and distributed applications.
05 · SMALL MODULAR REACTORS — THE INDUSTRIAL USE CASE
SMRs can decouple industrial clean baseload from the residential grid — and that changes the ethics.
The Union Budget has allocated ₹20,000 crore for the development of indigenous SMRs. Strategically, SMRs do something interesting for the grid’s ethical architecture: they can be sited near industrial clusters, providing dedicated clean baseload to industry without straining the rural residential network.
This connects directly to the Part 03 argument on load shedding. The “revenue versus need” dilemma that drives urban-industrial prioritisation in the current grid stems partly from industry and residential households competing for the same constrained capacity. Dedicated industrial SMRs decouple that competition.
PARTNERSHIPS · SMR VENDOR ARCHITECTURE — BARC + NTPC BARC has designed three indigenous SMRs: the BSMR-200 (200 MWe pressurised water reactor), the SMR-55 (55 MWe), and a 5 MWt high-temperature gas-cooled reactor. ₹20,000 crore under the Nuclear Energy Mission (Union Budget 2025–26) targets at least five indigenously-designed SMRs operational by 2033, with lead units at Tarapur (Maharashtra) and Vizag (Andhra Pradesh). NTPC is in active talks with international partners: Rosatom (Russia), Westinghouse Electric and Holtec International (United States), and EDF (France). The historical chokepoint — Section 17(b) of India's civil-nuclear-liability law, which exposed equipment suppliers to open-ended legal risk and kept them out of the Indian market for over a decade — is the structural reason these announcements are only now becoming plausible.

The risk is that SMRs become the easy way to deliver clean power to industry while the residential and rural grid continues to lean on coal and load-shedding. The deployment sequencing matters.
06 · LIABILITY AND RESTORATIVE JUSTICE
The Nuclear Liability Fund is the closest thing Indian energy policy has yet produced to structured victim compensation.
Pre-SHANTI, India’s nuclear liability regime sat under the Civil Liability for Nuclear Damage Act (CLNDA) 2010 — a regime designed to attract foreign suppliers but criticised for caps that potentially under-compensated victims of any catastrophic incident. The SHANTI Act overlays a graded structure: routine incidents handled by operator liability, major incidents drawing on the Nuclear Liability Fund.
Mapped back to the Energy Justice framework from Part 02:
▸ Restorative Justice: the Nuclear Liability Fund is the closest thing Indian energy policy has yet produced to a structural commitment to compensate victims of energy-system failures.
▸ Recognition Justice: the graded structure recognises that incidents occur on a spectrum and that response design must too.
▸ Procedural Justice: the question that remains open is whether affected communities have a meaningful role in claim-determination under the Fund.
This is one of the cleanest examples of the Energy Justice framework being institutionalised in Indian law — the kind of move that the framework in Part 02 was specifically designed to produce.
THE VERDICT
Nuclear’s role in 2026 is not as a marginal contributor competing with renewables. It is as the dispatchable floor that lets the renewable share continue to grow. The SHANTI Act has reframed who can build that floor and how they are held to account. The execution risk — actually delivering 14 GW of net new capacity by 2031–32 — is the binding constraint, and it will be visible in the next 18 months of project sanctions.
| The Act is now law. The 22.38 GW by 2031–32 target is now a calendar commitment. The question for the nuclear industry, regulators and private capital: which is the binding constraint — capital, technology, regulatory throughput, or public trust? Your answer determines what should change next. |

Part 8 — The Thorium Dream: On 6 April 2026, the Prototype Fast Breeder Reactor at Kalpakkam achieved first criticality. India now has the only operating fast breeder reactor outside Russia. What that means for the Three-Stage Programme, the thorium fuel cycle, and why India’s 25% share of global thorium reserves is an energy security asset — if the programme can execute.
