The power within the atom: Nuclear energy comes from the core of an atom, called the nucleus.  Within the nucleus, there’s an immense amount of energy.

Nuclear energy stocks can add diversification to your investment portfolio, as they tend to have low correlation to traditional energy sources like oil and gas.

Unfortunately, there aren’t many pure-play nuclear energy listed companies. The nuclear power sector in India is still largely government-controlled.
However, there are a few NSE-listed companies  who have involvement in it.

A major engineering and construction conglomerate. L&T plays a vital role in the construction of nuclear power plants in India. 

A state-owned company specializing in power generation equipment. They manufactures various components for nuclear power plants

A heavy engineering company that manufactures equipment for various industries, including the nuclear sector.  

A large infrastructure company with some involvement in the nuclear power sector. 

One of India’s largest power companies with a growing interest in renewable energy sources. While their primary focus isn’t nuclear. But they may have in future.
