Nuclear reactor construction refers to the planning, engineering, and building of nuclear power facilities designed to accommodate reactors for controlled nuclear fission. It involves activities including site development, reactor installation, and deployment of safety and cooling infrastructure. The primary objective of nuclear reactor construction is to establish facilities capable of producing large-scale, low-carbon electricity while also supporting scientific research and industrial applications.
The primary reactor types in nuclear reactor construction include pressurized water reactors (PWR), boiling water reactors (BWR), pressurized heavy water reactors (PHWR), gas-cooled reactors (GCR), fast neutron reactors (FNR), and small modular reactors (SMR). Pressurized water reactors (PWRs) are nuclear reactors that utilize high-pressure water as both a coolant and moderator to transfer heat from the reactor core to a secondary system, where steam is generated to produce electricity. These reactors incorporate advanced technologies such as Generation III reactors, Generation IV reactors, and other advanced reactor technologies, with construction undertaken through stages and arrangements including turnkey contracts, engineering, procurement and construction (EPC), design-build contracts, and construction management. Key applications include baseload electricity generation, desalination and process heat, marine propulsion, load balancing and peak demand, and district heating and cogeneration, serving end users such as utilities, government bodies, research organizations, and others.
Tariffs are influencing the nuclear reactor construction market by increasing the costs of imported steel, reactor components, safety systems, and specialized instrumentation required for reactor projects. Pressurized water reactors, boiling water reactors, and small modular reactors across Asia-Pacific, Europe, and North America are particularly affected because of their reliance on imported high-precision components. Nevertheless, tariffs are encouraging domestic manufacturing of reactor components, regional fabrication capabilities, and innovation in modular and enhanced-safety reactor technologies, strengthening long-term construction efficiency and project viability.
The nuclear reactor construction market research report is one of a series of new reports from The Business Research Company that provides nuclear reactor construction market statistics, including nuclear reactor construction industry global market size, regional shares, competitors with a nuclear reactor construction market share, detailed nuclear reactor construction market segments, market trends and opportunities, and any further data you may need to thrive in the nuclear reactor construction industry. This nuclear reactor construction market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The nuclear reactor construction market size has grown strongly in recent years. It will grow from $54.68 billion in 2025 to $57.88 billion in 2026 at a compound annual growth rate (CAGR) of 5.9%. The growth in the historic period can be attributed to rising global demand for nuclear energy, increasing adoption of small modular reactors, growing reliance on high-precision components, expansion of government-supported nuclear projects, and increasing research and development activities.
The nuclear reactor construction market size is expected to see strong growth in the next few years. It will grow to $71.64 billion in 2030 at a compound annual growth rate (CAGR) of 5.5%. The growth in the forecast period can be attributed to increasing deployment of advanced reactor technologies, rising adoption of digital project management tools, development of modular and turnkey reactor solutions, expansion of low-carbon electricity infrastructure, and growth in nuclear safety and monitoring systems. Major trends in the forecast period include integration of advanced nuclear reactor technologies, deployment of smart construction monitoring systems, adoption of Generation III and Generation IV reactors, implementation of artificial intelligence-based project planning, and expansion of modular reactor and small modular reactor deployment.
The rising need for clean energy is expected to propel the growth of the nuclear reactor construction market going forward. Clean energy refers to energy produced from renewable or low-emission sources that minimize environmental impact and reduce greenhouse gas emissions. The demand for clean energy is increasing due to growing awareness of environmental sustainability, as clean energy helps reduce greenhouse gas emissions and address climate change. Nuclear reactors contribute to clean energy objectives by providing a reliable, large-scale, and low-carbon source of power, supporting stable and sustainable electricity generation. For instance, in June 2024, according to the International Energy Agency, a France-based intergovernmental organization, worldwide investment in clean energy reached $80 billion in 2024, increasing from $67 billion in 2023. Therefore, the rising need for clean energy is driving the growth of the nuclear reactor construction market.
Leading companies operating in the nuclear reactor construction market are focusing on advancements in nuclear technology, such as bilateral nuclear reactor development agreements, to enhance advanced nuclear energy capabilities and promote the deployment of next-generation reactor technologies. A bilateral nuclear reactor development agreement refers to a formal, legally binding arrangement between two sovereign nations aimed at jointly developing, constructing, or deploying nuclear reactor technologies. For example, in October 2025, Slovakia's Prime Minister Robert Fico announced a government-approved agreement with the United States to develop a new nuclear reactor at the Jaslovske Bohunice site in western Slovakia. The planned reactor, expected to generate over 1,000 megawatts, will be fully state-owned and represents a multi-billion-euro investment aimed at expanding Slovakia's nuclear energy capacity. The project involves collaboration with U.S. nuclear technology providers and aligns with regional trends of nuclear expansion in Central and Eastern Europe, supporting energy security, clean electricity generation, and long-term infrastructure modernization.
In October 2024, Google LLC, a US-based technology and internet services company, partnered with Kairos Power LLC for an undisclosed amount.
