LONDON, GREATER LONDON, UNITED KINGDOM, December 2, 2025 /EINPresswire.com/ -- Nuclear Reactor Construction Market Growth Forecast: What To Expect By 2025?
The size of the nuclear reactor construction market has seen a significant expansion over the past few years. It is projected that it will increase from $51.41 billion in 2024 to $54.38 billion in 2025, with a compound annual growth rate (CAGR) of 5.8%. The historic growth can be linked to factors such as amplified energy demands, augmented government backing for nuclear projects, continual investments in large-scale power generation, a greater emphasis on energy security, along with increasing urbanization and population expansion.

Strong expansion is anticipated in the nuclear reactor construction market over the forthcoming years, with its value expected to reach $67.18 billion by 2029, growing at a compound annual growth rate (CAGR) of 5.4%. The surge during the forecast period is due to factors such as increased adoption of small modular reactors, the growing trend towards low-carbon energy, replacement of aging reactors, focus on sustainable baseload power and an increase in global collaborations for nuclear programs. The forecast period will also witness key trends such as advancements in reactor technology, ongoing innovation in modular construction, improvements in safety and waste management technologies, automation of construction processes and the development of next-generation nuclear technologies.

What Are Key Factors Driving The Demand In The Global Nuclear Reactor Construction Market?
An increased demand for environmentally friendly power is predicted to stimulate the expansion of the nuclear reactor construction market. Clean energy, derived from renewable or low-emission resources, aids in lowering environmental impacts and diminishing greenhouse gas emissions. This demand is rising due to heightened consciousness about environmental sustainability, as this type of energy helps to mitigate greenhouse gas emissions and tackle global warming. Nuclear reactors play a significant role in these eco-friendly initiatives by offering a dependable, large-scale, and low-carbon energy solution, which facilitates stable and sustainable power production. For example, the International Energy Agency, a France-based intergovernmental organization, revealed in June 2024 that the global investment in clean energy tallied up to $80 billion in 2024, a jump from $67 billion in the previous year, 2023. Consequently, the augmenting need for clean energy is fuelling the expansion of the nuclear reactor construction industry.

What Are Some Emerging Trends In The Nuclear Reactor Construction Market?
The focal point of several major corporations in the nuclear reactor construction industry is advancing nuclear technology. This is often seen in the form of bilateral nuclear reactor development agreements which boost the development and propagation of advanced nuclear energy and future-generation reactor technologies. The term ""bilateral nuclear reactor development agreement"" denotes a legally binding pact between two independent countries with the aim of co-developing, building, or establishing nuclear reactor technologies. For example, in October 2025, Robert Fico, the Prime Minister of Slovakia, publicized a government-endorsed agreement with the United States to construct a new nuclear reactor at the Jaslovské Bohunice site located in western Slovakia. The envisaged reactor, projected to produce over 1,000 megawatts, is set to be completely state-controlled and poses a multi-billion-euro investment dedicated to enlarging Slovakia's nuclear energy capabilities. The initiative involves cooperation with U.S. nuclear technology suppliers and harmonizes with the regional trends of nuclear growth in Central and Eastern Europe, promoting energy safety, environmentally friendly electricity production, and extensive infrastructure modernization.
