Global Nuclear Equipment and Services Industry Report Version 1.0 | Evidence cutoff 2026-10-13 | Global scope This report examines the global suppliers of equipment, engineering, fuel-cycle processing and technical services used by civilian nuclear-power plants. It covers construction, operation, life extension and the back end. Uranium feed appears as supply-chain context; electricity sales, uranium mining revenue, military uses and medical-isotope revenue are outside the market boundary. The commercial opportunity depends on both new projects and the existing fleet. The report follows how qualified equipment becomes an operating plant and how long-term fuel, inspection and maintenance contracts create service demand. Announced projects, orders, revenue and cash flow represent different stages. The analysis uses original disclosures and preserves their reporting periods and business boundaries. Sources were reviewed on 13 October 2026, with a public-information cutoff of that date. No unified global equipment-and-services revenue total is asserted. The share figure is explicitly limited to 2025 uranium-enrichment service capacity. Future production dates remain company plans. This is version 1.0.

[I01] Part 1 Industry Story Part 1: Industry Story | One reactor enters service, an entire supply chain comes into view On 29 April 2024, Georgia Power announced that Unit 4 at Plant Vogtle in Georgia, United States, had entered commercial operation. Unit 3 had entered service on 31 July 2023. A same-day securities filing confirmed Unit 4's placement in service. The milestone marked the transition from construction, commissioning and acceptance to electricity supplied commercially.[S01][S02] The participants performed different jobs. Georgia Power is a co-owner, Southern Nuclear operates the plant, and Bechtel was brought in during 2017 to help complete the engineering, procurement and construction of Units 3 and 4. Bechtel reported a peak project workforce exceeding 9,000. Commercial operation depended on coordinated delivery by owners, operators, contractors and construction workers.[S01][S03] Vogtle offers a concrete way to understand this industry. Equipment becomes useful through installation, system integration, commissioning and regulatory acceptance; services continue during operation. The author's interpretation is that nuclear equipment and services form a group of businesses spanning the plant lifecycle. Competitiveness therefore includes technology, delivery quality, verifiable operating performance and long-term maintenance capability.[S14] Milestones also need precise interpretation. When EDF announced Flamanville 3's first grid connection on 21 December 2024, it said further tests, connections and disconnections would follow as output increased towards full power. First grid connection, commercial operation and sustained operation provide different evidence. Supplier achievements should be assessed against the stage actually completed, alongside subsequent engineering and financial disclosures.[S13] Part 2 Industry History Part 2: Industry History | From electricity experiments to a lifecycle industry The starting point depends on the definition. DOE records that EBR-I first produced usable fission electricity on 20 December 1951, initially lighting four 200-watt bulbs. IAEA identifies Obninsk's supply to a national grid in June 1954 as another milestone. Calder Hall opened in 1956 as an important full-scale commercialization example. Experimental electricity, grid supply and full-scale commercial facilities represent distinct stages; an unqualified claim of the world's first would obscure them.[S04][S05][S24] During the 1960s and 1970s, nuclear moved from demonstration towards large orders. David Fischer's IAEA-published history describes demonstration reactors operating in leading industrial countries by the early 1960s and greater interest after the 1973 oil crisis. Orders were already declining by the mid-1970s, before Three Mile Island, while optimistic capacity forecasts later proved excessive. The author's reading is that energy-security needs encourage procurement, but demand, construction costs and economic conditions can change investment decisions; development does not follow a continuously accelerating curve.[S07] Accidents reshaped equipment and service requirements. On 28 March 1979, equipment failures, a malfunctioning valve, misleading indications and operator actions contributed to a partial core meltdown at Three Mile Island Unit 2. DOE describes subsequent improvements in operator training and the establishment of INPO in 1979 to improve plant management, training and operation. Reliability therefore requires attention to equipment, instrument information and people's understanding of the entire system.[S08] Chernobyl Unit 4's accident occurred on 26 April 1986. INSAG-7 examined design deficiencies, regulatory arrangements and safety culture. The Convention on Nuclear Safety, adopted on 17 June 1994 and effective from 24 October 1996, covers regulation, technical safety, resources, quality assurance and emergency preparedness, supported by reporting and peer review. Equipment and engineering services supplied across borders consequently need to accommodate national regulation and international safety cooperation.[S09][S11] Fukushima Daiichi's accident on 11 March 2011 reinforced attention to extreme external events. IAEA's technical assessment describes earthquake and tsunami impacts on cooling and containment, with multiple units, sites and surrounding infrastructure potentially affected together. The author's interpretation is that power, cooling, instrumentation and emergency measures must be assessed as an integrated system. Additional components provide meaningful improvements when accompanied by analysis of common-cause failures, independence and accident response arrangements.[S10] Mature plants created another development path. IEA's 2019 analysis highlighted ageing reactors built during the 1970s and 1980s in advanced economies. On 12 December 2025, NRC announced renewed licences for Browns Ferry's three units permitting operation up to 80 years, following safety and environmental reviews. This illustrates continuing opportunities for equipment upgrades and engineering services; actual operating periods remain dependent on plant conditions and regulatory decisions.[S19][S15] Decommissioning also became long-term business. Calder Hall stopped generating in 2003, started defuelling in 2011 and announced completion of fuel removal in 2019, with further decommissioning still ahead. The author's interpretation is that ending electricity sales does not end engineering responsibilities. Historic plants create work across successive stages, while owners need to plan the associated funding, facilities and execution capability.[S06] The next commercialization wave includes large reactors, SMRs and other advanced reactors. IAEA defines SMRs as units of up to 300 MWe and highlights factory assembly and modular installation. Its 2023 article records Akademik Lomonosov entering commercial operation in May 2020 with two 35 MWe reactors. On 23 April 2026, Bechtel announced field execution at TerraPower's Natrium Kemmerer Unit 1 as EPC partner. That is a construction milestone for another advanced-reactor route; it does not establish commercial operation or competitive costs.[S16][S22] These developments explain two sources of demand: existing plants require maintenance, upgrades, lifetime extension and decommissioning, while new projects require design, manufacturing, construction and commissioning. Procurement timing, risks and competitive advantages differ. The author's framework examines them within one lifecycle value chain and distinguishes individual markets, keeping claims about each technology or service tied to the evidence available. Part 3 Market Landscape Market boundaries: different deliveries behind one plant This report defines the industry as specialist equipment, engineering, fuel-cycle processing and technical services purchased throughout the life of civilian nuclear-power plants. The nuclear island includes vessels, steam generators and reactor pumps; the conventional island includes turbines and their services. Operations require fuel, instrumentation and control, inspections and upgrades, while the back end includes packages, dismantling and waste-related services. Electricity sales, uranium mining itself, military work and medical-isotope revenue fall outside this research boundary. [M06][M09][M11] Each activity has its own suppliers, approvals and contracts. A diversified company can cooperate with another supplier in one activity and compete in another. Supplier nationality, reactors served and consolidated revenue therefore provide different information. This report uses a value-chain matrix and reserves quantitative shares for one clearly defined service segment. [M09][M11] The value chain: new construction and operating services Customers for nuclear equipment and services are chiefly plant owners, project organisations and operating utilities. This report treats nuclear-grade materials and the fuel chain as supporting upstream activities, while focusing on reactor technology, nuclear-island and turbine-island equipment, I&C, construction, maintenance, life extension and decommissioning. Electricity sales and supplier revenue have different economic meanings and cannot be added to estimate this equipment-and-services market. Value-chain analysis must follow both new projects and the operating fleet. New construction creates demand for design, long-lead equipment and site work; operating plants require fuel, outages, replacement components and modernisation. Product catalogues and disclosed contracts suggest that suppliers can serve both demand streams, but responsibilities, pricing and revenue recognition remain contract-specific. This is an analytical inference.[V02][V12][V14] Upstream: heavy forgings and fuel processing address different constraints Upstream supply includes heavy castings and forgings, special materials, heat treatment and precision machining. Doosan lists forgings for reactors and steam generators. JSW's 2024 integrated report describes pressure-vessel and steam-generator components and turbine/generator shafts. These examples show that upstream value lies in producing components for specific equipment requirements, rather than simply supplying steel by weight.[V13][V21] The supporting fuel chain is distinct. Cameco participates in uranium production, conversion and some fuel manufacturing; Urenco supplies enrichment; Orano's Front End includes chemistry and enrichment; Westinghouse, Framatome and GE Vernova-led Global Nuclear Fuel participate in fabrication or fuel services. Mine output, conversion kgU, enrichment SWU and assembly counts measure different stages and cannot form one capacity indicator.[V01][V02][V04][V06][V15] At year-end 2025, Cameco disclosed about 83 million kgU of UF6 conversion commitments, while Urenco's order book was EUR 21.3 billion, extending into the 2040s. These are multi-year supply arrangements, not 2025 revenue. Fuel security helps explain why technology vendors discuss reactor deployment and subsequent fuel services together, although actual commitments depend on each contract.[V01][V04] Midstream: reactor technology, nuclear-island equipment and I&C Reactor-technology vendors provide design systems and technical services, while manufacturers build particular components; these roles can overlap. Westinghouse combines reactor technology with operating-plant equipment and fuel. Former GE Hitachi is named GE Vernova Hitachi Nuclear Energy (GVH) in current official material and supplies reactor technology, fuel and services, including BWRX-300 deployment support. Rosatom spans fuel, construction, generation and back-end management, making business boundaries essential.[V02][V15][V16] Nuclear-island equipment includes reactor vessels and internals, steam generators, coolant pumps, pressurisers and handling equipment, with configurations varying by reactor type. Framatome, Doosan and BWXT each cover parts of this scope. Curtiss-Wright supplies AP1000 coolant-pump technology; Dongfang lists nuclear- and turbine-island supply capabilities; Shanghai Electric's 2025 sustainability report records coolant pumps and nuclear/turbine-island supplies for Zhangzhou unit 1. This does not establish direct competition across every reactor design.[V03][V07][V10][V12][V18][V22] I&C covers monitoring, control and protection. Doosan's MMIS includes emergency safety functions; Framatome reports new-build and modernisation work in safety I&C; Curtiss-Wright's portfolio includes I&C and nuclear qualification support. A useful analytical comparison examines compatibility, nuclear qualification and continuing support before comparing prices or order values.[V03][V10][V12][V27] Turbine islands and construction: responsibilities follow the project The turbine island converts steam energy into electricity through turbines, generators and associated water-steam systems. Arabelle Solutions supplies turbine-island technology and services. In January 2026 it announced selection by Bechtel and Westinghouse for three turbine-generator sets and related equipment at Poland's first nuclear plant. Reactor technology, construction and turbine equipment represent different responsibilities; selection does not mean the plant has been completed.[V25] Korean project arrangements also show this division of labour. KHNP signed the final two-unit Dukovany contract in June 2025. KEPCO E&C subsequently disclosed an architect-engineering contract with KHNP covering auxiliary procurement and licensing support. In February 2026, Doosan announced a contract of about KRW 320 billion with Czech subsidiary Doosan Skoda Power for two turbine/control-system sets, linking Korean project organisation with Czech equipment capabilities.[V11][V23][V24] These examples suggest that EPC and other delivery organisations manage equipment interfaces as well as engineering, procurement and construction responsibilities. Similar contract labels do not establish identical schedule or cost exposure. The value-chain diagram should place construction firms such as Bechtel separately from I&C manufacturers, and intra-group equipment contracts must not be counted twice as industry sales. This is an inference from the disclosed scopes.[V11][V24][V25] Downstream: operating plants extend equipment relationships into services After delivery, utilities continue buying outage maintenance, parts, inspections and upgrades. Most recurring Westinghouse Operating Plants business is arranged through contracts lasting three to more than ten years. Doosan lists maintenance, replacement, engineering and I&C updates; Arabelle provides turbine/generator overhauls and serves legacy equipment made by other manufacturers. Service opportunities can therefore involve both a vendor's own equipment and other installed brands.[V02][V14][V17] Major-component replacement reconnects manufacturing with field engineering. Framatome reported such work in North America and South Africa in 2025 and began replacing four Flamanville 2 steam generators in November. BWXT supplies commercial nuclear equipment, fuel and engineering/maintenance and acquired Kinectrics in 2025. Kinectrics adds materials testing, operating inspections, lifecycle management and licensing support, illustrating the need for evidence on equipment fitness as well as field execution.[V03][V07][V26] Spare parts also face declining OEM support. Framatome's Nuclear Parts Center describes quality records, compatibility, qualification and acceptance requirements for safety-related items while some original manufacturers reduce support or exit. The analytical implication is that suppliers must establish suitability and preserve auditable evidence, not merely locate replacements. Supplier analysis and life-extension support must also be distinguished from an actual licensing decision.[V27] Life-extension support also includes licensing analyses. Westinghouse lists integrated plant assessment, time-limited aging analysis and environmental-report support; Framatome covers licence renewal, aging and asset management and modernisation. These services help utilities prepare for continued operation, while actual extension depends on regulatory approval and plant-specific conditions.[V28][V29] Decommissioning and waste services continue the equipment lifecycle Decommissioning involves dismantling, decontamination, packaging, transport arrangements and radioactive-waste management. Orano's Back End combines recycling, nuclear packages and services, dismantling/services and engineering; its 2025 revenue was EUR 2.352 billion. This is a portfolio of end-of-lifecycle activities rather than a pure decommissioning-market figure, and it does not imply identical spent-fuel pathways in every country.[V06] Rosatom's 2025 operating results include spent-fuel and radioactive-waste management, while Kinectrics also provides waste-related capabilities. Such overlapping roles show that upstream, midstream and downstream are analytical categories rather than exclusive company classifications. Project scope, material categories and long-term responsibilities help explain back-end business models better than a single group-revenue figure.[V16][V26] Contracts and estimate revisions can also affect back-end performance. Orano identified a one-off Japanese-utility contribution in the 2024 comparison base and end-of-lifecycle estimate revisions affecting 2025 adjusted earnings; its H1 2026 disclosure also reported disruption in Mining and Front End. These factors must be separated before attributing group earnings changes to decommissioning demand.[V05][V19] Financial evidence: reporting boundaries matter more than simple rankings Financial disclosures validate activity without automatically defining a global market. Framatome reported 2025 revenue of EUR 5.399 billion and new orders of EUR 5.924 billion. BWXT Commercial Operations revenue was USD 853.070 million but also included medical activities. The segment reported USD 586.158 million in H1 2026 revenue and USD 1,600.454 million in June-end backlog. Backlog is remaining contractual work rather than current sales, and half-year revenue should not simply be doubled.[V03][V07][V08] Curtiss-Wright's 2025 group sales of USD 3,498.372 million and Naval & Power sales of USD 1,503.002 million both include activities outside commercial nuclear power. Urenco enrichment revenue and Orano fuel-chain revenue also refer to different stages. Operator sales, supplier group sales, nuclear-segment revenue and contract values must remain distinct. This report describes competitive roles and bounded disclosures rather than adding incompatible figures or ranking global equipment-and-service companies from them.[V04][V06][V09] Contract structures also govern reported revenue, cash and risk. BWXT describes fixed-price and time-and-materials commercial contracts, with large custom-component and service revenue generally recognised over time and most contracts paid at milestones. New orders, revenue recognition and cash collection can therefore fall in different periods. Assessing suppliers requires connecting contract execution, cost estimates, payment terms and cash flow.[V07] Global demand: the operating fleet and new construction WNA’s 8 October 2026 table lists 442 operable reactors with 405,227 MWe net capacity and 80 under construction with 87,031 MWe gross capacity. Operable means grid-connected; construction includes suspended projects. Net and gross capacity cannot be added directly. These are demand indicators, not supplier orders or revenue. [M02] Regional differences: different weights of services and construction The same table lists 94 operable reactors in the USA and 57 in France. Construction includes 38 in China, eight in India, seven in Russia and four each in South Korea, Turkey and Egypt. The mix suggests different entry points: replacement equipment, maintenance and fuel for established fleets, and manufacturing and engineering where construction is stronger. This is an inference from reactor status, not national supplier shares; individual procurement arrangements still matter. [M02] Competition: technology platforms overlap with equipment and services Framatome spans nuclear steam-supply systems, heavy components, instrumentation and control, fuel and maintenance; EDF reports work on more than 380 reactors. GE Vernova’s Nuclear Power unit covers boiling-water-reactor technology, fuel, support services and SMRs developed with Hitachi, while some nuclear-turbine services sit in Steam Power. Technology ownership, equipment manufacture and recurring services are therefore not exclusive categories, and reactor-service footprints can overlap. [M09][M11] A comparable segment: global enrichment-service capacity The chart uses one WNA 2025 capacity table, in thousand SWU/year: Rosatom 29,133; Urenco 17,300; CNNC 13,789; Orano 7,500; INB and JNFL together 355. Author-calculated shares are 42.8%, 25.4%, 20.3%, 11.0% and 0.5%. They describe enrichment capacity, not revenue or deliveries; CNNC is estimated and some capacity primarily serves domestic demand. [M01] The rows sum to 68,077, versus the published total of 68,076 thousand SWU/year: a roughly 0.0015% discrepancy that the source does not explain. Shares use the row sum; all source rows are preserved. [M01] Orders and capacity: demand signals need a delivery timetable Urenco disclosed a €27.3bn order book at June 2026, up from €21.3bn at December 2025, with contracts extending into the 2040s. H1 revenue fell from €830.4m to €645.4m; the company mainly cited delivery timing. Long-term commitments and one half-year’s revenue therefore measure different things, and a multi-year backlog is not annual market size. [M03][M04] Expansion also takes time. Orano’s 7.5-million-SWU/year Georges Besse II plant is adding a planned 2.5 million SWU/year, with first production scheduled for 2028 and full commissioning for 2030. Planned capacity belongs in the pipeline until commissioned, rather than in the current-capacity share chart. Orders, investment approval, construction and production are separate stages. [M05] Company finances: useful signals with different reporting boundaries Framatome disclosed 2025 revenue of €5,399m and new orders of €5,924m; EDF reported H1 2026 order intake of about €2.7bn. GE Vernova’s 2025 Nuclear Power revenue was US$1,018m, but nuclear-related turbine services also appear in Steam Power alongside coal activities. Such figures describe specific businesses; they do not provide comparable whole-industry share numerators. [M08][M09][M12] BWXT Commercial Operations reported US$853.070m in 2025, including medical activities and US$231.0m contributed by its Kinectrics acquisition. Orano’s €2,696m H1 2026 group revenue includes mining, front-end and back-end activities. Acquisitions, currencies, business boundaries and supply-chain transactions require adjustment. Our primary-source review found no common-period, common-perimeter global revenue total that avoids double counting. We therefore omit an unverified total; this is a limitation of the evidence reviewed, not a claim that the market has no size.

Part 4 Industry Challenges Part 4: Industry Challenges | Turning demand into deliverable, profitable projects Engineering delivery. Quality problems can change schedules and funding needs. On 16 December 2022, EDF raised Flamanville 3's estimated completion cost from EUR 12.7 billion to EUR 13.2 billion, in 2015 euros excluding construction-period interest. It principally linked the schedule adjustment to studies of stress-relief heat treatment for repaired welds; pass-through weld repair required over twelve months of studies and qualification. The author's interpretation is that designs, processes and interfaces should mature together. Earlier validation can reduce rework, but cannot guarantee timely delivery. This was a dated estimate, not a final outturn cost.[S12] Financing and risk allocation. IEA's 2025 report identifies capital intensity, long construction and complexity as financing challenges; repeated designs and clearer revenues can help. Sizewell C's UK investment decision on 22 July 2025 specified an approximately GBP 38 billion construction target in 2024 prices, with RAB arrangements sharing costs among consumers, taxpayers and investors. The author's interpretation is that financing reallocates risks and cash-flow timing; cost control remains necessary. Targets, electricity-price commitments and realised returns require separate assessment.[S20][S18] People and execution. Vogtle illustrates the scale of specialized staffing, while retaining experience requires continuing projects and training. On 6 October 2026, Bechtel and the University of South Carolina announced a nuclear workforce fund connecting universities, technical colleges and training partners across engineering, project management and skilled trades. The announcement establishes a programme, not demonstrated graduates, resolved shortages or measured productivity gains. The author's interpretation is that suppliers expanding orders should also assess qualified personnel, site management and training times.[S03][S21] Fuel and diversification. IEA's 2025 report attributes over 99% of uranium-enrichment capacity to four suppliers: a specific capacity measure, not nuclear-equipment revenue share. Some advanced reactors requiring HALEU also need downstream processing. DOE awarded six deconversion frameworks on 8 October 2024 for subsequent tasks. The author's interpretation is that procurement supports demand visibility, while supply requires facilities, approvals and delivery. Ceilings are not revenue; 2024 supply conditions are not treated as current.[S20][S17] SMR economics. IAEA's 2023 explanation says lower upfront capital per unit still requires deployed evidence of economic competitiveness. The author's interpretation is that factory assembly must be supported by repeat orders, transportation, installation, site infrastructure and approvals. Target prices are promises or forecasts; learning effects require observed hours, costs and performance across repeated deliveries. Comparisons with large reactors need consistent price years, financing assumptions, cost boundaries and electricity-output measures.[S16] Lifetime extension. IAEA SSG-48 recommends managing physical ageing and obsolescence, re-evaluating embrittlement and cumulative fatigue, and retaining auditable, retrievable evidence. The author's interpretation is that services create value by turning inspections, equipment records and safety analyses into a reviewable case for continued operation. Regulatory permission allows continued operation; economic viability also depends on upgrade costs, outage plans and subsequent performance. Browns Ferry's 80-year permissions cannot establish the same potential for every plant.[S14][S15] Safety, decommissioning and public acceptance. Fukushima underlines the need to review extreme external hazards and protective arrangements. DOE's 2024 explanation addresses spent-fuel transport, storage and disposal planning, including community participation in interim-storage siting. Calder Hall's lengthy defuelling illustrates post-generation requirements. The author's interpretation is that facilities, transport, permissions, funding and continuing responsibilities belong within the project boundary. Progress on storage does not establish completion of final disposal.[S10][S23][S06] The quality of order conversion depends on these issues. The author's assessment framework asks what stage permits cover, whether financing is in place, whether key processes are qualified, whether equipment is accepted and whether operational results match announced milestones. Framework agreements, construction progress and commercial operation represent different stages; supplier revenue and profit require contract execution and financial evidence. This framework does not predict any company's profits or a definitive future market size. Appendix Supporting Evidence [S01] Vogtle Unit 4 enters commercial operation Publisher Georgia Power.
