15 Biggest Nuclear Energy and Reactor Companies in the World

In this article, we will discuss the 15 Biggest Nuclear Energy and Reactor Companies in the World. You can skip our industry overview and go directly to the 5 Biggest Nuclear Energy and Reactor Companies in the World.

Nuclear energy has been in the conversation lately partly due to its ability to provide clean energy as the world transitions to zero emissions but also in part due to the rising geopolitical tensions around the world. The conflict between Russia and Ukraine has increased concerns around geographic sovereignty, with countries like Belgium and Japan declaring to prolong the lifetime of their nuclear plants.

Although the use of nuclear weapons in war situations is certainly an issue of concern for the world, the use of nuclear energy for the production of energy is a more refreshing concept. Nuclear power facilities emit almost no greenhouse gases, and in the last five decades, around 70 gigatonnes of carbon dioxide emissions have been avoided by using nuclear power. The amount of carbon dioxide emission per unit of electricity through nuclear power plants is equivalent to one-third compared to solar power. In support of the struggle for a zero-carbon world, more than 200 countries vowed to a phasing down of coal for energy use at the CoP26 climate summit in 2021, and as the transition occurs, nuclear power will continue to get further traction among climate activists.

Scientists have continued to make strides in nuclear technology, and recently, a group of researchers in the United States were able to successfully complete nuclear fusion ignition, which is a process involving the bombarding of light elements to form heavier elements. Nuclear fusion is a reaction reported to generate more energy than the energy used to start the reaction. Although we are still in the early stages of this technology, the potential of nuclear fusion is immense since it can sustainably provide low-carbon energy.

Nuclear fusion startups have been generating interest among investors owing to the potential of the technology. TAE Technologies, a startup working on producing energy through nuclear fusion, raised $250 million earlier in July 2022, with Google and Chevron Corporation being part of the funding round. With the recent breakthrough in nuclear fusion technology, the space is set to attract large investment inflows over the coming years. According to Bloomberg, investments in nuclear fusion tech amounted to $1 billion in 2022, a triple-fold increase in funding from 2020.

Setting up a large-scale nuclear power plant requires significant spending and capital investments which is why the space is dominated by government-owned entities around the world. The issue of large upfront capital investments is addressed through SMRs (small modular reactors). These reactors are smaller in size and power output compared to traditional reactors and can generate power up to 300 MW. Apart from requiring significantly less capital investment, these plants are mobile and can be set up and transported to the site where they are required. These plants have relatively simple designs and are relatively safer in nature due to their smaller size. Although there are some advantages attached with SMRs, recent studies have found out that SMRs actually generate more nuclear waste than conventional nuclear plants. As per the report, SMRs would produce 30 times more radioactive waste per unit of power generated than traditional reactors.

According to International Energy Agency (IEA) data, global energy generation from nuclear plants increased by 3.5% in 2021 compared to 2020, reversing a decline of over 4% brought on by the COVID-19 pandemic. A total of 439 nuclear reactors were in operation as of May 2022 in about 30 different nations. At the time, the United States had the most operational nuclear power reactors, with 92 units. The number of new reactors under construction reached 55 as of May 2022, including 2 in the United States and 18 in China. The total electricity supplied by nuclear power plants throughout 2021 was reported at 2653.1 TWh, accounting for 10% of the total global electricity generation, which is forecasted to increase to 14% by 2050.

Our Methodology

To come up with the 15 biggest nuclear energy and reactor companies in the world, we identified the biggest nuclear energy and reactor companies and ranked these companies in ascending order in order of their market cap. In the case of private companies, we have used the annual revenue of 2021 to estimate each company's market capitalization. For these companies we used a price-to-revenue multiple of 2 as a crude measure of market value. We should also note that most of the US based nuclear energy companies have other operations that generate significant percentage of their revenues, and we made no effort to estimate the value of their nuclear energy operations. Instead, we used the entire market cap of these companies in our rankings.
