The Nuclear Power Reactor Decommissioning Market size was estimated at USD 3.30 billion in 2024 and expected to reach USD 3.82 billion in 2025, at a CAGR 15.68% to reach USD 7.91 billion by 2030.

The global nuclear decommissioning landscape is witnessing an unprecedented surge in activity as aging reactor fleets approach the end of their operational lifespans. Decommissioning has evolved into a multifaceted discipline requiring meticulous coordination across regulatory, technical, and environmental domains. As the world transitions toward advanced energy systems, the safe and efficient dismantling of legacy nuclear power assets has become a paramount priority for governments, operators, and communities alike.

Today, decommissioning projects span the full spectrum of complexity, from rapidly completed small research reactors to large commercial units that demand decades-long closure strategies. According to industry assessments, 213 reactors worldwide have been closed, with 190 units awaiting or currently in various stages of decommissioning. The United States alone accounts for 41 of these closed reactors, yet only 17 have fully completed technical decommissioning processes and a mere five have been released as greenfield sites. This disparity underscores the intricate regulatory requirements and logistical challenges that define modern decommissioning operations.

Recent years have seen sweeping reforms and technological breakthroughs that are reshaping the contours of reactor decommissioning. On May 23, 2025, an Executive Order directed comprehensive reform of the Nuclear Regulatory Commission to expedite licensing, streamline regulatory barriers, and balance safety with the economic benefits of nuclear energy. Concurrently, the NRC’s proposed rule for transitioning plants to decommissioning phases seeks to tailor requirements to the reduced radiological risks inherent in shutdown reactors, encompassing aspects such as emergency preparedness, security, funding assurances, and environmental considerations.

At the same time, industry leaders are leveraging advanced digital solutions and robotics to optimize project execution. Jacobs has pioneered the integration of digital decision-making tools and digital twins to enhance asset management and predictive maintenance across complex sites including Sellafield and Hanford. These innovations are being complemented by remote-operated cutting systems, three-dimensional site characterization, and automated waste segmentation technologies that improve safety and accelerate dismantling timelines. Underpinning these shifts is a renewed emphasis on collaborative frameworks between licensees, technology providers, and government agencies, setting the stage for more agile and cost-effective decommissioning interventions.

The cumulative impact of recent U.S. tariffs on critical raw materials has had profound implications for nuclear decommissioning supply chains and project economics. Tariffs enacted under Section 232 introduced a 25 percent levy on steel and aluminum imports effective March 12, 2025, triggering immediate cost pressures across metal-intensive operations. With President Trump’s announcement on May 30, 2025 to double these tariffs to 50 percent, steel prices have surged by 16 percent in the U.S. market, while aluminum price differentials have widened by as much as 139 percent compared to Europe.

These tariff escalations have led to increased lead times for steel components, higher import costs, and budgetary uncertainties for decommissioning projects that depend on heavy-duty cutting equipment, structural frameworks, and waste container fabrication. In May 2025 alone, U.S. steel mills incurred $39 million in additional costs for imported feedstocks and ferrous scrap due to a 10 percent duty applied earlier in April. Against this backdrop, decommissioning teams are reevaluating procurement strategies, exploring domestic sourcing alternatives, and re-aligning contracts to mitigate the impact of volatile metal prices and shifting trade policies.

The landscape of nuclear reactor decommissioning is shaped by a nuanced interplay of service types, project phases, reactor designs, waste streams, and ownership models that collectively define market segments and strategic imperatives. Service offerings span dismantling and demolition processes, which include both manual and mechanized methodologies, as well as comprehensive planning and consulting engagements that encompass feasibility studies and regulatory compliance support. The restorative dimension integrates land remediation and landscaping expertise, while waste management services address offsite treatment, onsite processing, and secure disposal practices.

Projects typically progress through sequential phases-starting with decontamination to remove residual radioactivity, advancing through the systematic dismantling of structural and mechanical systems, and transitioning to extended post-decommissioning surveillance regimes. Site restoration activities then rehabilitate properties for potential reuse, followed by specialized waste processing protocols that ensure safe packaging, transportation, and storage of high level, intermediate level, and low level waste. Ownership structures, whether under government jurisdiction or private enterprise, further influence funding arrangements and contractual frameworks, driving sector-specific priorities and risk management approaches.

Regional dynamics exert a decisive influence on the pace, funding models, and technical approaches to reactor decommissioning. In the Americas, the United States leads global activity with 41 closed reactors, supported by mature regulatory institutions and a network of licensed low level waste disposal facilities. Canada’s portfolio of six shut-down power units underscores the importance of cross-border collaboration in sourcing decontamination technologies and leveraging logistical synergies for offsite waste treatment.

Across Europe, the Middle East, and Africa, major decommissioning programs in the United Kingdom and Germany-each with 36 closed reactors-operate under stringent environmental and safety standards, financed through segregated public funds and industry levies. France has decommissioned 14 units and is pioneering advanced fuel recycling initiatives, reflecting a strategic orientation toward circular nuclear fuel cycles. Meanwhile, in the Asia-Pacific region, Japan’s 27 closed reactors are progressing through phased dismantling following the 2011 nuclear incident, and emerging programs in South Korea and China are establishing pilot frameworks for future closures. Notably, Asia accounts for over 79 percent of global nuclear capacity growth, even as it prepares for an increasing wave of plant retirements in the coming decade.

The competitive landscape for decommissioning services features a range of specialized providers differentiated by technical depth, geographic reach, and integrated waste management capabilities.
