Three Companies, One Reactor: What NTPC, Adani and Jindal Steel Actually Agree On

Why Three Rivals All Picked the Same Reactor

Here's what's actually happening when NTPC, Adani and Jindal Steel each say they are starting with the 700 MWe PHWR: none of them are making a technology bet. They are making a supply chain bet - and that distinction is the whole story.

A Small Modular Reactor sounds like the more exciting choice. It is smaller, newer and gets the bulk of the global nuclear headlines. But building any reactor in commercial numbers depends less on how clever the design is and more on a boring question: can you actually get the forgings, the pressure tubes, the calandria, the fuel bundles and the trained contractors to build it, on time, at a predictable cost?

For the 700 MWe PHWR, the answer is yes - Adani's own India head put a number on it, saying the design is "almost indigenized, 90-95%." For SMRs, that ecosystem barely exists yet, anywhere in the world.

The Mechanism: De-Risking Before Innovating

Three completely unconnected companies chasing three different capacity targets - NTPC at 30 GWe, Adani at 10 GWe, Jindal Steel at 18 GWe - all converged on the identical answer because the constraint they're solving for is the same: a newly private, still-unproven regulatory environment created by the SHANTI Act, 2025.

When you are the first wave of private players in a sector the state has run alone for over sixty years, you do not want your commercial success to also depend on a first-of-a-kind reactor design. You want the technology risk to be zero, so all your risk-management energy can go toward the parts that are genuinely new - private ownership, private liability, private licensing under the Atomic Energy Regulatory Board.

That is also why every executive on that panel was careful to frame PHWR as a first phase, not a final answer. Jindal Steel's own representative said plainly that PHWRs "alone would not be sufficient" to reach 100 GWe - PWRs and SMRs are expected to enter once the regulatory and financing playbook has actually been tested and proven at scale.

Where India Stands Globally This is

where India's position is genuinely distinctive. Most countries opening nuclear power to private capital for the first time have no domestic reactor design mature enough to de-risk that transition - they import technology and import the construction risk with it.

India's three-stage nuclear programme, built around PHWRs since the Bhabha era, means the country already possesses a proven, standardised, AERB-approved design with a real vendor base behind it. That is a genuine head start very few liberalising nuclear markets have and it is precisely why India's private entrants aren't reaching for SMRs the way analysts elsewhere assumed they might.

The exam-relevant insight here isn't "India is expanding nuclear energy." It's that in a liberalising strategic sector, regulatory certainty and supply chain maturity - not the most advanced available technology - are what actually move private capital first.
