Nuclear Decommissioning Market Size, Share, Trends, and Industry Analysis - Global Forecast to 2036 | USD 30.17 Billion Market Driven by Reactor Closures, Robotics, and Waste Solutions

Dublin, Oct. 27, 2026 (GLOBE NEWSWIRE) -- "Nuclear Decommissioning Market Size, Share, and Industry Analysis - Global Forecast to 2036" has been added to ResearchAndMarkets.com's offering.

The global nuclear decommissioning market was valued at USD 18.50 billion in 2025 and is estimated to reach USD 19.24 billion in 2026. Revenue is projected to increase to USD 30.17 billion by 2036, representing a CAGR of 4.6% during the 2026-2036 forecast period. Market growth is supported by an expanding inventory of permanently closed reactors, publicly funded legacy programs, immediate dismantling strategies, and rising investment in waste treatment, robotics, remote handling, and site remediation.

The report assesses commercial and research reactors, fuel cycle facilities, and government-owned legacy nuclear sites. Its market coverage includes planning and Engineering , decontamination, dismantling and demolition, radioactive waste treatment, conditioning, packaging, transport, interim storage, spent fuel management, site remediation, and license termination. Deep geological repository construction and operation, together with high-level waste treatment plants at government sites, are excluded from the market valuation.

Shutdown Pipeline Supports Long-Term Demand

According to the International Atomic Energy Agency, seven reactors in Russia, China, and Belgium were permanently shut down in 2025. The U.S., the U.K., and Germany account for half of all reactor shutdowns recorded to date. Germany closed Isar 2, Emsland, and Neckarwestheim 2 in April 2023, while Belgium shut Doel 1, Doel 2, and Tihange 1 in 2025. EDF is also decommissioning nine reactors across four technologies in France.

Large government-backed programs provide stable, multi-decade demand. The U.K. National Audit Office forecasts that Sellafield decommissioning will cost GBP 136 billion on an undiscounted basis at 2023-24 prices. Expenditure reached GBP 2.7 billion in 2023-24, while final building demolition is expected by 2125. In Japan, approximately 880 tons of fuel debris remain within the three Fukushima Daiichi reactors affected by the 2011 accident, with Total Fina Elf clean-up costs estimated at about JPY 23 trillion.

Immediate dismantling is gaining preference because it retains experienced personnel, aligns with regulatory expectations, and reduces long-term surveillance costs. Engie 's decision to pursue immediate dismantling at Tihange 1 reflects this trend. However, reactor lifetime extensions and restarts may delay new decommissioning projects. Holtec's Palisades plant returned to service in August 2025, becoming the first U.S. reactor restored from decommissioning. Constellation Energy plans to restart the former Three Mile Island Unit 1 by 2027 as the Crane Clean Energy Center, supported by a 20-year Microsoft power agreement. Belgium has also extended the operating lives of Doel 4 and Tihange 3.

Cost uncertainty, schedule overruns, skilled labor constraints, and the limited availability of final repositories remain significant market challenges. Four of Sellafield's oldest storage facilities are running up to 13 years behind schedule, while TEPCO does not anticipate full-scale debris removal at Fukushima Daiichi Unit 3 before 2037.

Technology and Investment Opportunities

Robotics, remote handling, characterization systems, advanced cutting technologies, decontamination solutions, waste minimization, and metal recycling represent major growth opportunities. EDF subsidiary Cyclife has treated 145,000 tonnes of waste over 30 years, demonstrating the increasing commercial importance of waste processing and recycling capacity.

Liability transfer models are also reshaping the competitive landscape. Specialist companies are acquiring closed plants, assuming licenses, and managing decommissioning programs under dedicated funding structures. Holtec manages Oyster Creek, Pilgrim, and Indian Point, while the March 2025 agreement between Engie and the Belgian government transfers waste and spent fuel responsibility in exchange for a EUR 15 billion lump-sum payment.

Segment Outlook

• Facility type: Legacy & government nuclear sites are expected to hold the largest market share in 2026, driven by extensive historic waste inventories and long-duration public funding. Power reactors are projected to record the highest CAGR as recently closed plants progress into active dismantling.
• Reactor type: Pressurized water reactors are expected to lead the market in 2026 because of their prevalence across shutdown fleets in Germany, France, Belgium, and the U.S. Boiling water reactors are forecast to grow at the highest CAGR, supported by major Japanese and German programs.
• Strategy: Immediate dismantling is anticipated to account for the largest share and achieve the fastest growth. Deferred dismantling remains relevant where operators allow radioactivity to decay or require additional time to accumulate funds, while entombment remains uncommon.
• Activity: Waste Management is expected to generate the largest share of 2026 revenue because treatment, conditioning, packaging, transport, and storage represent substantial portions of Total Fina Elf project costs. Dismantling & demolition is projected to grow fastest as shutdown reactors enter physical execution phases.
• Capacity: Reactors above 1,000 MW are expected to lead due to larger dismantling scopes, waste volumes, and project budgets. The 801 MW to 1,000 MW segment is forecast to achieve the highest CAGR.
• End user: Government agencies & legacy site owners are expected to dominate in 2026, while utilities & plant owners are projected to record the strongest growth as European and Asian reactors advance through decommissioning.

Regional Nuclear Decommissioning Market

Europe is expected to remain the largest regional market in 2026. Growth is supported by Sellafield and other U.K. Nuclear Decommissioning Authority sites, Germany's fleet-wide dismantling program, Belgium's recent closures, and EDF 's activities in France. Spain, Sweden, Switzerland, Italy, Lithuania, and Central and Eastern European countries also maintain active programs.

Asia-Pacific is projected to record the highest CAGR through 2036, led by Fukushima Daiichi, Fukushima Daini, and other Japanese facilities, alongside programs in South Korea and Taiwan. India and China are also evaluated as part of the regional outlook.

North America represents a significant market, supported by U.S. commercial reactor dismantling, federal legacy projects, and Canadian research and legacy sites. Planned U.S. restarts may moderate the near-term addition of projects, but ongoing work at closed plants and government facilities will sustain demand. Activity across the Rest of the World remains comparatively limited.

Competitive Landscape

The nuclear decommissioning market is moderately consolidated. Suppliers compete on safety performance, regulatory compliance, high-hazard project capability, waste treatment and recycling capacity, cost certainty, and their ability to assume licenses and liabilities. Strategic priorities include robotics investment, expanded processing infrastructure, acquisitions of closed plants and service businesses, joint ventures, workforce development, and long-term government contracts.

Companies profiled include EnergySolutions, Holtec International, Orano, Electricite de France S.A. through Cyclife, Westinghouse Electric Company LLC, Framatome, Amentum Holdings, Inc., BWX Technologies, Inc., Bechtel Corporation, Fluor Corporation, AtkinsRealis Group Inc., Babcock International Group PLC through Cavendish Nuclear, Studsvik AB, GNS Gesellschaft fur Nuklear-Service mbH, NUKEM Technologies Engineering Services GmbH, Nuvia, Veolia Nuclear Solutions, and Hitachi, Ltd.
