원전 해체 서비스 시장 기회, 성장 촉진요인, 업계 동향 분석 및 예측(2026-2035년)

The Global Nuclear Decommissioning Service Market was valued at USD 9.9 billion in 2025 and is estimated to grow at a CAGR of 6.8% to reach USD 19.4 billion by 2035.

Market growth is driven by the increasing number of nuclear facilities approaching the end of their operational lifespan, creating a long-term pipeline of mandatory decommissioning projects worldwide. As aging reactor fleets are permanently retired, demand for specialized dismantling, radioactive waste management, site restoration, and environmental remediation services continues to increase. Rising inventories of radioactive waste generated during plant shutdown and dismantling activities are further supporting investment in comprehensive decommissioning solutions. Government funding and long-term financial commitments remain essential to sustaining project execution, while evolving regulatory requirements continue to strengthen demand for highly specialized service providers. The market is also benefiting from growing emphasis on safe facility closure, environmental protection, and efficient project management throughout the decommissioning process. Continuous advancements in decontamination technologies, waste handling capabilities, and project planning are improving operational efficiency while supporting compliance with stringent safety standards. Supported by expanding retirement programs and long-term regulatory obligations, the global nuclear decommissioning service market is expected to witness steady growth throughout the forecast period.

The immediate dismantling segment accounted for 56% share in 2025 and is expected to grow at a CAGR of 6.8% through 2035. This approach focuses on initiating dismantling activities shortly after permanent facility closure, allowing sites to progress toward future redevelopment within a defined timeframe. The strategy continues to gain preference because it helps reduce long-term maintenance responsibilities, lowers ongoing operational costs, and accelerates site restoration while supporting efficient project execution.

The commercial power reactors segment held 70% share in 2025. Its leadership reflects the extensive scope, technical complexity, and long project duration associated with commercial reactor decommissioning. These projects require comprehensive engineering expertise, specialized waste management capabilities, regulatory compliance, and advanced project management services, making them the largest source of market demand.

North America Nuclear Decommissioning Service Market accounted for 26.6% share in 2025 and is anticipated to register a CAGR of 15.1% through 2035. The United States remains the primary regional market, supported by a substantial number of active decommissioning projects and a well-established regulatory framework that provides long-term funding visibility and structured project oversight. Continued investment in safe reactor retirement, radioactive waste management, and environmental restoration is expected to sustain strong demand for specialized decommissioning services across the region.

Major companies operating in the global nuclear decommissioning service market include AECOM, Altrad Group, Amentum, Ansaldo Nucleare, AtkinsRealis, Babcock International, Bechtel, Enercon Services Inc., EnergySolutions, Fluor Corporation, Holtec International, Jacobs Solutions, KDC Veolia, NorthStar Group Services, Nuclear Decommissioning Authority, Orano, Sogin S.p.A., Studsvik, TRC Companies, and Westinghouse Electric. Companies operating in the nuclear decommissioning service market are strengthening their competitive position through investments in advanced dismantling technologies, radioactive waste management capabilities, and specialized engineering expertise. Market participants are expanding service portfolios to deliver integrated decommissioning solutions covering planning, decontamination, dismantling, waste processing, transportation, and site restoration. Strategic partnerships, acquisitions, and long-term government contracts are helping companies broaden their project pipelines and enhance geographic presence. Businesses are also investing in digital project management tools, robotics, remote handling technologies, and workforce training to improve operational efficiency while maintaining strict safety standards.
