India’s Nuclear Story Is Moving Up the Ladder

Private participation in nuclear power can create opportunities across engineering, equipment, financing and technology without making every company a reactor operator. For years, private companies in India’s nuclear ecosystem mostly worked behind the scenes building specialised equipment, engineering systems and supporting plant construction. Now the story is changing. The SHANTI Act has opened the door to broader private-sector participation, while India targets a major expansion in nuclear capacity. One company already has decades of experience inside this ecosystem: Larsen & Toubro (L&T).

L&T says it has contributed to all 22 nuclear reactors currently operational in India and manufactures critical nuclear equipment including reactor vessels, steam generators and other specialised systems. In 2026, L&T also dispatched another 700 MWe steam generator for NPCIL’s nuclear fleet programme. The bigger learning is this: A nuclear expansion does not only create an opportunity for reactor operators. It can also expand the ecosystem of engineers, manufacturers, EPC companies and specialised equipment suppliers. For investors, the important exercise is not simply identifying a “nuclear stock”, but understanding where each company sits in the nuclear value chain and how much of its future business could actually come from that opportunity.
