Steady Growth in the Nuclear Power Market
According to Mordor intelligence reports, the nuclear power market is projected to grow from 402.60 GW in 2025 to 414.66 GW by 2030, reflecting a modest 0.59% CAGR. While new large-scale reactor construction remains selective, the market is stabilizing due to ongoing refurbishment programs, long-term operational extensions, and increasing interest in small modular reactors (SMRs).
Across major regions, governments continue to prioritize energy security, firm baseload power, and decarbonization targets. This is pushing utilities and industrial users to reassess nuclear energy as a reliable, round-the-clock option that complements variable renewable sources.
Key Trends Influencing the Nuclear Power Market
Rising Demand for Clean and Stable Power Supply
More countries are reviewing nuclear energy to support long-duration grid reliability as renewable penetration increases. Data centers, heavy industries, and expanding urban hubs require stable electricity, which strengthens the case for nuclear power. In regions where energy security has become a priority, nuclear lifetime extensions are gaining political and financial support.
Long-Term Operation and Uprating Programs
The extension of operating licenses from 40 to 60 or even 80 years has become a core strategy to maintain capacity at a lower cost than new construction. These programs include component replacement, containment reinforcement, and digital instrumentation upgrades.
Although challenges around aging reactor vessels and regulatory deadlines persist, long-term operation is expected to remain a major contributor to market stability through 2030.
Shift Toward SMRs and Advanced Reactor Designs
SMRs are gaining traction due to their smaller footprint and ability to be deployed in modular formats. Designs under review in the United States, United Kingdom, and Canada are moving closer to commercial timelines for early 2030s deployment.
Growing Role of Nuclear in Industrial Heat and Hydrogen
A rising share of industrial buyers-particularly in steel, cement, chemicals, and hydrogen-are exploring nuclear energy as an alternative to coal and gas boilers. High-temperature reactors capable of producing heat above 700°C are being assessed for long-run process requirements. Pilot programs in Europe and North America aim to demonstrate feasibility by the end of the decade, opening a new revenue line for reactor vendors and utilities.
