結論と提言

Global Nuclear Reactor Construction Market size was valued at USD 52.3 billion in 2023 and is poised to grow from USD 53.24 billion in 2024 to USD 61.41 billion by 2032, growing at a CAGR of 1.8% during the forecast period (2025-2032).

The nuclear reactor construction market is experiencing a resurgence as nations prioritize cleaner energy sources to address climate change and bolster energy security. This shift away from fossil fuels is prompting a reevaluation of nuclear power's role in achieving carbon neutrality, leading to a spike in reactor construction, especially in high-demand regions like Asia-Pacific and the Middle East, supported by favorable government policies. A notable trend is the increasing adoption of small modular reactors (SMRs), which offer advantages like lower costs, enhanced safety, and flexible deployment, appealing to both developed and emerging economies. While challenges such as construction costs, regulatory hurdles, and public safety concerns persist, advancements in technology, construction methods, and AI-driven project management tools are enhancing efficiency and mitigating risks within the sector.

Driver of the Global Nuclear Reactor Construction Market

The growing global emphasis on decreasing greenhouse gas emissions is driving a surge in the demand for nuclear energy. Unlike solar and wind power, which can experience intermittent supply issues, nuclear energy provides a reliable baseload power source. Nations like China, India, and the UK are making substantial investments in nuclear reactor construction to achieve their climate targets for 2030 and 2050. For example, China's 14th Five-Year Plan outlines the development of several new reactors to realize its ambitious decarbonization strategy. Furthermore, nuclear energy is recognized as a clean alternative and a crucial element for ensuring energy security and independence, particularly amid disruptions in the global fuel market.

Restraints in the Global Nuclear Reactor Construction Market

The Global Nuclear Reactor Construction market faces a substantial restraint due to the significant financial challenges associated with building nuclear reactors. The lengthy timelines for these projects, typically ranging from 8 to 10 years, necessitate substantial upfront investments amounting to billions of dollars before any returns can be expected. Moreover, cost overruns frequently occur, as exemplified by the Vogtle nuclear plant expansion in Georgia, U.S., which has experienced numerous delays and budget increases. Consequently, this financial uncertainty can deter private sector investment, thereby restricting nuclear energy adoption primarily to nations with robust governmental support or state-owned utility companies.

Market Trends of the Global Nuclear Reactor Construction Market

The Global Nuclear Reactor Construction market is experiencing a significant shift driven by the integration of AI and digital twin technology, enhancing operational efficiency and safety. As noted by the collaboration between Russia's Rosatom and Nvidia for the Akkuyu Nuclear Power Plant, these innovations allow for the creation of virtual replicas of reactors, enabling real-time monitoring and predictive maintenance while minimizing disruptions. This trend is expected to streamline construction processes, reduce timelines, and elevate safety standards across the industry, indicating a transformative potential that fosters both investment and competitiveness in nuclear energy infrastructure globally.
