簡介目錄

全球核子反應爐建設市場預計將從 2025 年的 547.2 億美元成長到 2031 年的 654.1 億美元，複合年成長率為 3.02%。

該市場涵蓋與受控核分裂發電設施相關的全部工程、採購和施工 (EPC) 活動。其主要驅動力是全球對低碳基本負載電源的迫切需求，這對於實現嚴格的脫碳目標和國際氣候變遷協議至關重要。此外，各國正在增加對核能基礎設施的投資，以加強能源安全並降低與石化燃料相關的地緣政治風險，從而確保國內能源供應的穩健性和多元化。

最大的市場 北美洲

世界核能協會報告稱，到2025年，全球將有70座核子反應爐在建，顯示各方正持續努力擴大發電能力，尤其是在亞洲市場。儘管如此，核能產業仍面臨諸多挑戰。特別是，高昂的初始投資成本和漫長的專案開發週期會帶來巨大的財務風險，並可能阻礙新業務的快速實施。

市場促進因素

推動新建核子反應爐的主要動力之一是人工智慧 (AI) 和超大規模資料中心對電力需求的激增。科技公司正積極尋求獲得基本負載電力，以運作其高能耗的運算基礎設施並實現永續性目標。這種需求促使超大規模公司與核能開發商之間建立直接合作關係。例如，2024 年 10 月，亞馬遜網路服務 (AWS) 宣布計劃領投約 5 億美元的 C-1 輪資金籌措，以推動先進核能項目的開發，這是「亞馬遜與 X-energy 合作公告」的主導。如此巨額的資金注入提供了至關重要的財務穩定性，使核子反應爐設計能夠進入實際建造階段。

全球為實現碳中和和緩解氣候變遷所做的努力進一步推動了核電市場的長期成長。世界各國政府正在重新審視其能源政策，並日益認知到核能發電在向清潔能源轉型中的關鍵作用。根據核能（IAEA）發布的《2050年能源、電力和核能發電預測》（2024年9月），樂觀預測顯示，到2050年，全球核能發電裝置容量可能達到950吉瓦。這項樂觀預測促使一些快速發展地區的具體項目核准。例如，路透社2024年報告稱，中國國務院核准了五個新的核能項目，每個項目包含11座核子反應爐，總投資額預計約2,200億元。這種戰略性的政府支持清晰地表明了國家指南如何推動基礎設施建設。

市場挑戰

全球核子反應爐建設市場擴張的主要障礙在於其龐大的財務負擔，這源自於極高的初始資本投入和漫長的專案開發週期。與通常採用模組化設計的可再生能源設施不同，核能設施需要巨額的前期投資，而這些投資必須在盈利前數年才能落實到位。這使得投資者面臨與利息累積和流動性相關的巨大風險。這些專案的資本密集特性造成了很高的進入門檻，往往阻礙了私營部門的參與，而且專案本身也十分複雜，通常依賴難以預測的政府資金籌措計劃和貸款擔保。

這種經濟壓力在近期專案績效數據中得到了清楚體現，凸顯了阻礙投資的風險。國際能源總署（IEA）在2025年報告中指出，已開發國家新建核能工程通常平均會經歷約八年的工期延誤，最終成本飆升至最初預算的近2.5倍。如此巨大的成本超支和工期延誤顯著降低了核能發電相對於其他基本負載電源的商業性可行性，導致電力公司重新評估其對新專案的投入，並直接阻礙了整體市場成長速度。

市場趨勢

小型模組化反應器（SMR）設計的商業化正在改變市場格局，為傳統的大型基礎設施提供了擴充性的替代方案。與需要現場客製化設計的吉瓦級核電廠不同，SMR採用標準化設計進行工廠化生產，顯著降低了安裝風險和初始資本成本。這種轉變在各國採購政策中日益明顯，採購流程正從初步可行性研究轉向最終部署合約。例如，2025年6月，美國核能學會報告“英國勞斯萊斯贏得SMR競標”，指出英國政府已為該項目投入超過25億英鎊，並選擇一家本土公司作為英國首個模組化核子反應爐陣列的首選供應競標。此類投資能夠發出重要的市場訊號，重振供應鏈，並加速從設計到實際建設的過渡。

同時，除役燃煤發電廠的基礎建設改造為核能發電廠建設用地，正成為提升工程經濟效益的戰略手段。開發商傾向於選擇棕地（現有設施所在地），以便利用現有的高壓輸電線路、冷卻水使用權和經驗豐富的當地勞動力，從而有效降低待開發區項目的高昂成本。這項策略也符合旨在簡化替代石化燃料發電計畫許可流程的法律規範。根據美國核能協會（NRC）2025年12月發布的題為《NRC完成對TerraPower公司Kemeller專案的安全報導》的報告，開發商確認計畫於2031年開始在懷俄明州一家燃煤電廠附近建造一座345兆瓦的核子反應爐並投入商業運營。將先進的核能技術與現有能源資產結合，不僅能夠加速發電能力的擴張，還有助於振興工業區。

Product Code: 28822

The global nuclear reactor construction market is projected to expand from USD 54.72 billion in 2025 to USD 65.41 billion by 2031, demonstrating a compound annual growth rate (CAGR) of 3.02%. This market involves the full spectrum of engineering, procurement, and construction activities for facilities that generate electricity via controlled nuclear fission. Its core impetus stems from the urgent global need for low-carbon baseload power, essential for meeting rigorous decarbonization targets and international climate agreements. Furthermore, countries are increasingly investing in nuclear infrastructure to enhance energy security and reduce geopolitical vulnerabilities tied to fossil fuels, thus ensuring a robust and varied national energy supply.

CAGR 2026-20313.02%
Fastest Growing SegmentAdvanced Reactors
Largest MarketNorth America

As of 2025, the World Nuclear Association reported 70 nuclear reactors under construction globally, indicating a consistent push for increased capacity, particularly within Asian markets. Despite this expansion, the industry faces considerable obstacles, notably the high upfront capital costs and extended timelines for project development, which introduce significant financial risks and can hinder the swift implementation of new ventures.

Market Driver

A significant driver for new nuclear reactor construction is the escalating power demand from artificial intelligence and hyperscale data centers. Technology companies are actively pursuing carbon-free baseload power to operate their energy-intensive computational infrastructures and achieve sustainability objectives. This demand has spurred direct collaborations between hyperscale companies and nuclear energy developers. For instance, Amazon Web Services announced in October 2024, as part of its 'Amazon and X-energy Partnership Announcement', its commitment to lead a Series C-1 financing round with an investment of approximately $500 million to advance the development of advanced nuclear projects. These substantial capital infusions provide crucial financial stability, enabling reactor designs to progress toward physical construction.

Long-term market growth is further bolstered by global commitments to achieve net-zero carbon emissions and mitigate climate change. Governments are re-evaluating energy policies, increasingly recognizing nuclear power as a vital element of the clean energy transition. The International Atomic Energy Agency's 'Energy, Electricity and Nuclear Power Estimates for the Period up to 2050' (September 2024) indicates a high-case projection where global nuclear generating capacity could reach 950 gigawatts by 2050. This optimistic forecast translates into tangible project approvals in rapidly expanding regions; for example, Reuters reported in 2024 that China's State Council approved five new nuclear projects comprising 11 reactors, representing an estimated total investment of approximately 220 billion yuan. Such strategic governmental endorsements clearly illustrate how national directives stimulate infrastructure development.

Market Challenge

A major impediment to the expansion of the Global Nuclear Reactor Construction Market is the substantial financial strain imposed by extremely high upfront capital expenditures and extended project development schedules. Unlike renewable energy installations, which often employ modular designs, nuclear facilities demand enormous initial investments that must be secured many years prior to any revenue generation. This exposes investors to considerable risks related to interest accumulation and liquidity. The capital-intensive nature of these projects establishes a high entry barrier, frequently discouraging private sector involvement and making projects reliant on intricate, often unpredictable, government financing schemes or loan guarantees.

This economic pressure is clearly evident in recent project performance data, which underscore the risks that deter investment. The International Energy Agency reported in 2025 that new nuclear projects in advanced economies typically encountered construction delays averaging about eight years, with final costs escalating to nearly 2.5 times the original budget estimates. Such pronounced cost overruns and scheduling setbacks significantly diminish nuclear power's commercial viability when compared to other baseload energy sources, leading utilities to reconsider commitments to new developments and directly hindering the overall pace of market growth.

Market Trends

The market is being transformed by the commercialization of Small Modular Reactor (SMR) designs, which provide scalable options distinct from conventional large-scale infrastructure. Unlike gigawatt-class plants that demand customized on-site engineering, SMRs leverage standardized designs for factory manufacturing, thereby significantly reducing installation risks and initial capital expenses. This shift is increasingly apparent in national procurement approaches, evolving from preliminary feasibility studies to definitive deployment contracts. For instance, the American Nuclear Society reported in June 2025 that, in the 'U.K.'s own Rolls-Royce wins SMR competition', the government pledged over £2.5 billion to the program and chose the domestic firm as the preferred bidder for delivering the nation's inaugural fleet of modular units. Such investments generate crucial market signals, stimulating supply chains and facilitating the progression of designs to physical construction.

Simultaneously, the conversion of decommissioned coal infrastructure for nuclear plant siting is emerging as a strategic means to enhance project economics. Developers are favoring brownfield locations to capitalize on existing high-voltage transmission lines, water rights for cooling, and experienced local workforces, which effectively mitigates the considerable costs associated with developing greenfield sites. This strategy also aligns with regulatory frameworks aimed at simplifying the permitting process for projects that substitute fossil fuel generation capacity. As reported by the American Nuclear Society in December 2025, regarding the 'NRC completes safety review for TerraPower's Kemmerer project', the developer confirmed its plan to commence commercial operation of its 345-megawatt reactor, located near a Wyoming coal facility, by 2031. This integration of advanced nuclear technology with existing energy assets not only accelerates capacity expansion but also contributes to the revitalization of industrial communities.
