Nuclear power is experiencing a resurgence of interest globally as it is seen as a low carbon source of baseload electricity generation. After a slowdown in the last decade due to stringent regulations following the Fukushima disaster, the nuclear power industry has started gaining momentum again. Countries around the world are investing in new nuclear reactors as they aim to reduce dependence on fossil fuels and meet their commitment towards reduced carbon emissions under the Paris Agreement. However, high capital costs and construction delays continue to remain as challenges for widespread expansion of nuclear power globally.

 Growing Energy Demands

The world's demand for energy is continually increasing as populations increase and economies develop further. According to the International Energy Agency, the global energy demand is projected to grow over 25% between 2018 and 2040. Much of this increased demand will come from developing nations in Asia Pacific and Africa where living standards and energy consumption are rising rapidly. Nuclear power can play a vital role in meeting this escalating demand for clean, low-carbon energy by providing abundant baseload power. A single nuclear power plant can power over 1 million homes and displace enormous amounts of carbon emissions from fossil fuel power sources. As countries develop advanced nuclear technologies like small modular reactors, they will provide lower-cost options to satisfy electricity needs. Nuclear energy offers a densely efficient way to generate massive amounts of power without depending on unpredictable renewable sources. Maintaining global energy security will depend on developing diverse sources like nuclear that can reliably power economies around the clock.

Market Concentration and Competitive Landscape

Around the world, more countries are prioritizing climate change mitigation and setting ambitious renewable energy targets. Nuclear power produces zero direct carbon emissions and can be an important tool for lowering the carbon footprint of power sectors. The scientific consensus is clear that ust rapidly reduce global greenhouse gas emissions to avoid the worst impacts of climate change. Many analyses show that deep decarbonization goals will be extremely difficult to achieve without continued use and expansion of nuclear energy. Advanced economies in Europe and North America have pledged to become carbon neutral by 2050, which will require electrifying services like transportation, heating, and industries currently powered by fossil fuels. The massive amounts of low-carbon electricity needed can be generated through scaling up nuclear alongside renewable sources. Younger generations are also increasingly environmentally conscious and recognizing nuclear's benefits for slowing climate change. More policymakers and the public may grow to accept nuclear power as critical for transitioning to sustainable energy systems that protect the planet for future generations.

The high capital costs associated with setting up new nuclear power plants are a major factor restraining the growth of the global nuclear power market. Building a new nuclear power plant requires massive investments running into billions of dollars. According to data from the World Nuclear Industry Status Report 2022, the construction costs for plants commissioned in the recent decade have surged significantly compared to the previous decades. For instance, the Hinkley Point C nuclear power station currently under construction in the U.K. is expected to cost around USD 27 billion. Similarly, the Vogtle 3 and 4 reactors under construction in the U.S. are estimated to cost over USD 27 billion. Such high capital expenditure poses major budgetary challenges for utility companies and governments. The long construction periods of 5-10 years also means blocking huge amounts of capital for prolonged durations. Given the high risks and uncertainties involved in nuclear projects, many investors are reluctant to provide funds. The huge funds required also raise the price of electricity generated, impacting the affordability and competitiveness of nuclear power. The budgetary constraints and difficult investment environment have led to the cancellation of many planned projects in recent years. For example, projects worth over 180 GW of capacity have been cancelled or suspended in different countries like Japan, the U.S., and the U.K. since 2010, according to data from the International Atomic Energy Agency.

Opportunities: Small modular reactors

Small modular reactors (SMRs) present a compelling opportunity for growth in the global nuclear power market. SMRs offer several advantages over traditional large-scale nuclear plants that could help surmount many of the economic and social barriers impeding expansion of nuclear energy around the world.  SMRs are significantly smaller in size and power capacity compared to conventional nuclear reactors. Individual SMR units typically range from 50-300 MW electric each—small enough to be factory-fabricated and transported fully assembled to sites where power is needed. Their modular design allows for staggered construction, where additional units can be added as power demand grows. This “scalable” approach helps reduce upfront capital investment risks for utilities. SMRs also have enhanced safety features such as passive cooling systems and their small footprint allows various siting options including at decommissioned coal plants. Current trends around the world indicate growing interest in SMRs. According to a report by the International Atomic Energy Agency (IAEA) in 2021, over 70 SMR designs are in development globally with 15 countries having national programs. Recent public funding commitments and agreements also point towards increased SMR deployment in the coming years.  Similarly, Canada and Poland have signed an agreement for the export of Ontario-based GE Hitachi's BWRX-300 in early 2023.

In terms of reactor type, pressurized water reactor and pressurized heavy water reactor is expected to contributes 38.3% share of the market owing to their widespread use and proven operational safety records in 2025. Pressurized Water Reactors (PWR) are currently the most widely used reactor type globally owing to their versatile design and higher thermal efficiency compared to other reactor types. Over 90 PWR reactors are currently in operation worldwide, generating close to 300 GW of electricity. Their simple design with separate primary and secondary cooling loops makes them easy to operate and maintain. The reactor core is surrounded by pressurized water which transfers the heat to the steam generators located outside the reactor vessel. This offers stronger safety features by isolating radioactive material from the power generation system. Pressurized Heavy Water Reactors (PHWR) are predominantly used in Canada and India due to the availability of natural uranium as fuel. Over 20 PHWR reactors are currently operational with another 10 under construction. These reactors use heavy water (deuterium oxide) as both coolant and moderator. The use of heavy water allows PHWRs to use natural unenriched uranium as fuel and attain high breeding ratios for production of nuclear fuel. Their single self-pressurized heavy water system acts both as coolant and moderator, making the design compact. Moreover, proven 50 years of safe operation of PHWRs in Canada has demonstrated their excellent process control and safety characteristics.

Insights By Application: Increasing global electricity demand and focus on reducing carbon emissions

In terms of application, the energy segment is expected to contribute 38.3% of the market share due to steadily increasing global electricity demand and focus on reducing carbon emissions in 2025. Nuclear energy currently produces about 25% of the world's electricity without greenhouse gas emissions. Over 450 commercial nuclear reactors worldwide generate electricity to power homes and industries. Many countries are expanding their nuclear fleet as a sustainable and reliable alternative to fossil fuels to meet rising power needs of industrialization and combat climate change.
