India-Australia Civil Nuclear Pact: Which Companies Would Benefit?

Mumbai, July 15: India, Australia signed a civil nuclear pact during Prime Minister Narendra Modi’s recent visit. A detailed backgrounder has now been released on the Civil Nuclear pact, laying out the scale of the country’s nuclear build-out just as the agreement puts Australian uranium supply within reach.  

With 24 reactors already running across seven sites, 10 more under construction and Rs 20,000 crore earmarked in the FY26 Budget for small modular reactors, the numbers in the backgrounder offer a clearer read than the diplomatic language of the pact itself on which government arms and private players are positioned to gain. Here is a decoding of who benefits. 

On Tuesday evening, the Indian government’s Press Information Bureau came out with a backgrounder on the India-Australia Civil Nuclear pact. Here, we are decoding which government or private companies stand to benefit from the pact.  

India is scaling up its nuclear power programme to bolster energy security and back its clean energy transition, relying heavily on indigenous technology and long-term planning. The country currently runs 24 reactors across seven sites with 8.78 GW of installed capacity, comprising Pressurized Heavy Water Reactors (PHWRs), Boiling Water Reactors (BWRs) and Light Water Reactors (LWRs). Ten more reactors totalling 8,000 MW are under construction, with pre-project work underway on 10 additional units. Natural uranium fuels most PHWRs, with plutonium generated as a by-product; imported Australian uranium will help secure steady fuel supply.  

Longer term, India is building toward a thorium-based fuel cycle, tapping coastal reserves in Kerala, Tamil Nadu, Andhra Pradesh and Odisha via Fast Breeder Reactors that use plutonium as a bridge fuel. The government has also earmarked ₹20,000 crore in the FY26 Budget for indigenous Small Modular Reactors (up to 300 MWe each), targeting at least five operational SMRs by 2033. Together, these point to a wide-ranging shift in India’s power mix. 

Here’s a breakdown of which Indian-listed stocks stand to be impacted: 

1. Reactor fleet expansion (24 reactors, 10 more under construction, 10 more in pre-project stage)

This is a direct order-book driver for heavy engineering and EPC players: 

• BHEL — the sole domestic supplier of nuclear steam turbines and generators; contributes 56% of India’s installed nuclear capacity on the secondary side with a 59% domestic market share. It has already won the turbine island package contract for six of the ten new fleet-mode 700 MW PHWR reactors.  

• L&T (Larsen & Toubro) — involved in the civil and structural engineering supply chain for these new PHWR projects, alongside its broader heavy-engineering and EPC exposure.  

• Walchandnagar Industries — a long-standing DAE/NPCIL manufacturing partner that fabricates radiation-resistant components such as Calandrias (the reactor vessel) and End Shields.  

• MTAR Technologies — supplies about 20-25% of the total equipment scope for the core of a 700 MWe PHWR nuclear plant, including critical fuel-handling equipment.  

• Kirloskar Brothers and KSB Ltd — pumps and valves used across reactor cooling/plant systems. 

2. PHWR/BWR/LWR mix and uranium fuel supply

• NTPC — via its JV NTPC-ASHVINI (49% NTPC, 51% NPCIL), which has been approved to build, own and operate nuclear power plants, with its first project being the 2,800 MW Mahi Banswara Rajasthan Atomic Power Project. NTPC’s subsidiary is also exploring SMRs, PHWRs and FBRs.  

• Australian uranium supply doesn’t have a direct listed Indian pure-play (uranium mining stays with the government/UCIL, unlisted), but it de-risks fuel security for NTPC/NPCIL-linked plays and any future PHWR-linked order flow to BHEL/L&T. 

3. Thorium reserves (Kerala, Tamil Nadu, Andhra Pradesh, Odisha) and Fast Breeder Reactors

• This is a longer-dated theme tied to IREL (India) Limited (mines the monazite/thorium-bearing coastal sands) and to FBR-linked engineering work, again benefiting BHEL and L&T, and thematically Tata Power, which has flagged interest in next-gen reactor tech. 

• Note: India’s Kalpakkam Prototype Fast Breeder Reactor achieved first criticality in April 2026, which is the milestone that makes this thorium pathway commercially relevant sooner rather than later — a useful news hook if you’re writing this up. 

4. SMRs (₹20,000-crore Budget 2025-26 allocation, five SMRs targeted by 2033)

• BHEL, L&T, MTAR Technologies again lead here as the precision-engineering/EPC beneficiaries. 

• NTPC is in discussions with Holtec (US) on SMR tech and has a draft MoU with BARC. 

• Techno Electric & Engineering and Godrej Enterprises group entities have also signalled SMR interest in recent coverage, though these are smaller and more speculative angles. 

• Precision-component and forgings names like MIDHANI (Mishra Dhatu Nigam) could see tangential interest given SMR/defense-grade alloy overlap. 

Most of these are diversified conglomerates (L&T, BHEL, NTPC, Tata Power) where nuclear is one segment among many, so the “impact” is more of a sentiment/thematic re-rating trigger than a hard EPS mover in the near term — nuclear projects typically take 8 to 10 years from planning to operational revenue. Pure uranium-mining exposure doesn’t exist on Indian exchanges since there are no listed uranium mining companies in India; all domestic uranium mining sits with the unlisted UCIL.
