This trajectory reflects a compound annual growth rate (CAGR) of 9.5%, making it the fastest sustained growth rate recorded across all major energy infrastructure verticals in the current forecast cycle.

Key Market Drivers and Application Segments

1. The AI Data Centre Catalyst

The structural, 24/7 non-interruptible, and gigawatt-scale power demands of AI training and inference have established tech giants (Microsoft, Google, Amazon, Meta) as primary nuclear procurement drivers. Committed to securing over 10 GW of capacity through 2031, these hyperscalers view nuclear as the only viable, dispatchable, zero-carbon generation source capable of meeting their needs without economically prohibitive battery storage.

• Growth Dynamics: The AI Data Centre & Commercial & Industrial Power application is the fastest-growing segment in the report, expanding at a 21.6% CAGR from USD 9.6 billion (8% market share) in 2025 to USD 31.0 billion (15% share) by 2031.
• Historical Context: This constitutes the most consequential new source of nuclear procurement since the 1979 Three Mile Island accident structurally suppressed US nuclear development.

2. Baseload Power Generation & Grid Supply

Remaining the dominant application by market share, this segment is valued at USD 57.6 billion (42% share) in 2025 and is forecast to grow to USD 86.9 billion by 2031 at a 7.1% CAGR, driven by steady revenue streams from the existing global reactor fleet.

3. Industrial Process Heat & Green Hydrogen

Driven by decarbonization mandates in hard-to-abate sectors, this segment is growing at a 13.7% CAGR. Key catalysts include China's HTGR-PM-200 commercial precedent, X-energy’s high-temperature (935°C) Xe-100 reactor capabilities, and the integration of nuclear-derived hydrogen into the US DOE Clean Hydrogen Production Standard.

Technology and Construction Trends

NPP Construction & Engineering

As the largest industrial segment, Construction & Engineering commands USD 42.0 billion (35% share) in 2025, growing to USD 62.1 billion by 2031 (6.7% CAGR). While it experiences a modest market share dilution to 30% due to the rapid rise of SMRs, the segment remains robustly anchored by large-scale global projects:

• China: Driven by an aggressive domestic buildout program.
• Rosatom: Supported by 25+ international projects across Turkey (Akkuyu), Egypt (El Dabaa), and Bangladesh (Rooppur).
• Westinghouse: Anchored by the AP1000 4-unit program in Poland (targeted construction starting 2033).
• EDF: Driven by the EPR2 fleet program (6 confirmed, 8 proposed), bolstered by the Flamanville EPR grid connection in December 2024 providing a vital operational proof-of-concept.

Regional Performance: Asia-Pacific Dominance

Asia-Pacific stands as both the largest and fastest-growing regional market, set to expand from USD 50.4 billion (42% share) in 2025 to USD 95.2 billion (46% share) by 2031 at an 11.2% CAGR. Key country-level drivers include:

• China: Expanding from USD 27.7 billion to USD 54.3 billion to remain the dominant regional market driver.
• India: Scaling from USD 6.0 billion to USD 12.4 billion at a 12.9% CAGR, propelled by 10 new reactor approvals and a long-term target of 100 GW by 2047.
• Japan: Rising from USD 6.0 billion to USD 9.5 billion, driven by policy shifts enabling 12+ reactor restart approvals.
• South Korea: Increasing from USD 5.0 billion to USD 8.6 billion, accelerated by export successes such as the fully operational Barakah plant.

Strategic Competitive Landscape

The geopolitical and commercial landscape of the nuclear renaissance is defined by intense sovereign competition over technology exports. Three primary entities lead the race to secure global sovereign nuclear programs:

• Rosatom: Leading global project volume with 25+ active overseas deployments.
• Westinghouse: Expanding Western influence with major procurement wins across Poland, Bulgaria, and the Czech Republic.
• CGN / CNNC: Capitalizing on international partnerships to deploy Chinese reactor technology across the UK, Argentina, and Kenya.
